- Abstract
Introduction: In patients with frequent premature ventricular contractions (PVCs), palpitations may not always be directly caused by PVCs, and therefore, it is essential to establish symptom-rhythm correlations to determine the appropriate treatment. This study aims to analyze the palpitations and related factors in patients with frequent PVCs., Methods: The study enrolled patients with frequent PVCs who were not combined with other arrhythmias or structural heart disease. Through face-to-face consultation, patients were divided into symptomatic and asymptomatic groups. For symptomatic patients, the correlation between palpitations and PVC was further evaluated based on the temporal consistency of symptom onset and PVC occurrence. The demographic, clinical, and electrocardiogram features of the patients in each group were compared., Results: Of the 214 patients enrolled, 124(57.9%) experienced palpitations. Compared to the asymptomatic group, the symptomatic group had a higher proportion of females (63.7% vs. 47.8%; p = .020) and a higher proportion of subjects with anxiety (44.4% vs.14.4%; p = .000). Within the symptomatic patients, 72 (33.60%) who had palpitations that were clearly correlated with PVCs were classified as the PVC-relevant group. In this group, the PVC CI ratios were significantly lower (55% [52% -60%] vs. 62% [55% -67%]; p = .001) and the Post-PVC CI were longer (1170 [1027-1270] vs. 1083 [960-1180] ms; p = .018) than in the PVC-irrelevant group., Conclusion: A direct relationship between palpitations and PVCs could be established only in a minority of patients with frequent PVCs. PVCs with a relatively short PVC CI and a long post-PVC CI were more likely to cause palpitations, whereas palpitations lasting only a few seconds were more likely to be directly relevant to PVCs., (© 2024 The Author(s).

- Abstract
Enhanced external counterpulsation (EECP) is widely utilized in rehabilitating patients after percutaneous coronary intervention (PCI) and has demonstrated efficacy in promoting cardiovascular function recovery. Although the precise mechanisms of the therapeutic effects remain elusive, it is widely postulated that the improvement of biomechanical environment induced by EECP plays a critical role. This study aimed to unravel the underlying mechanism through a numerical investigation of the in-stent biomechanical environment during EECP using an advanced multi-dimensional 0/1D-3D coupled model. Physiological data, including age, height, coronary angiography images, and blood velocity profiles of five different arteries, were clinically collected from eleven volunteers both at rest and during EECP. These data contributed the development of a patient-specific 0/1D model to predict the coronary volumetric flow and a 3D stented coronary artery model to capture the detailed in-stent biomechanical features. Specifically, an immersed solid method was introduced to address the numerical challenges of generating computational cells for the 3D model. Simulations revealed that EECP significantly improved the biomechanical environment within the stented arteries, as evidenced by increased time-averaged wall shear stress (resting vs. 20 kPa vs. 30 kPa: 1.39 ± 0.4773 Pa vs. 1.82 ± 0.6856 Pa vs. 1.96 ± 0.7592 Pa, p = 0.0009) and reduced relative residence time (resting vs. 20 kPa vs. 30 kPa: 1.06 ± 0.3926 Pa
-1 vs. 0.89 ± 0.3519 Pa-1 vs. 0.87 ± 0.3764 Pa-1 , p < 0.0001). Correspondingly, low-WSS/high-RRT surfaces were obviously reduced under EECP. These findings provide deeper insights into EECP's therapeutic mechanisms, thereby offering basis to optimize EECP protocols for enhanced clinical outcomes in post-PCI patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
To combat the SARS-CoV-2 pandemic, innovative prevention strategies are needed, including reducing ACE2 expression on respiratory cells. This study screened approved drugs in China for their ability to downregulate ACE2. Daphnetin (DAP) was found to significantly reduce ACE2 mRNA and protein levels in PC9 cells. DAP exerts its inhibitory effects on ACE2 expression by targeting HIF-1α and JAK2, thereby impeding the transcription of the ACE2 gene. The SARS-CoV-2 pseudovirus infection assay confirmed that DAP-treated PC9 cells exhibited decreased susceptibility to viral infection. At therapeutic doses, DAP effectively lowers ACE2 expression in the respiratory systems of mice and humans. This suggests that DAP, already approved for other conditions, could be a new preventive measure against SARS-CoV-2, offering a cost-effective and accessible way to reduce SARS-CoV-2 spread., Competing Interests: Declarations.

- Abstract
Background: Immune checkpoint inhibitors (ICIs) are associated with an increased risk of major adverse cardiovascular events (MACE). Glucagon-like peptide-1 agonists (GLP1a), initially developed for type 2 diabetes mellitus (T2DM), have shown promising results in reducing cardiovascular events. We aimed to investigate the effect of GLP1a on cardiovascular events in patients receiving ICIs., Methods: We conducted a retrospective, propensity score-matched cohort study using the TriNetX database. We identified adults with cancer and T2DM who received ICIs between April 2013 and May 2023. The primary efficacy outcome was incident MACE, defined as a composite of myocardial infarction, need for coronary revascularization, heart failure, ischemic stroke, and cardiac arrest. The secondary efficacy outcomes were the individual components of MACE as well as myocarditis and pericarditis. Safety outcomes included the occurrence of immune-related adverse events, serious adverse events related to GLP1a use, and all-cause mortality., Results: We identified 7651 patients eligible for inclusion, among which 479 received GLP1a and 7172 received non-GLP1a diabetes medications. After matching (469 patients each), baseline characteristics were well-balanced. Over a median 12-month follow-up, the GLP1a cohort had a significantly lower MACE incidence than the non-GLP1a cohort (9.0 vs. 17.1 events per 100 patient-years) with a 54 % lower risk of MACE (Hazard ratio (HR),0.46 [95 % CI: 0.32-0.67]). There were reductions in myocardial infarction or need for coronary revascularization, heart failure, and all-cause mortality, with no differences in other cardiovascular events. GLP1a use did not increase risk of adverse events, including pancreatitis, biliary disease, bowel obstruction, gastroparesis, and immune-related adverse events., Conclusion: GLP1a use in cancer patients with T2DM receiving ICIs was associated with reduced MACE and all-cause mortality without an increased risk in serious adverse events., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr Neilan reported receipt of personal fees for consulting from Bristol Myers Squibb, Genentech, Roivant, Roche, and Sanofi, and receipt of grants from Bristol Myers Squibb, Abbott, and AstraZeneca.

- Abstract
Cytochrome P450 (CYP) epoxygenases metabolize arachidonic acid (AA) into biologically active epoxyeicosatrienoic acids (EETs), forming a pivotal metabolic pathway (AA-CYP-EETs-soluble epoxide hydrolase-dihydroxyeicosatrienoic acids) implicated in the progression of various disorders. Inflammation is a key contributor to the onset and progression of numerous systemic diseases, and EETs play a significant role in mitigating inflammation. Extensive research highlights the cardiovascular protective effects of EETs, which include vasodilation, anti-hypertensive, and anti-atherosclerotic properties. Interestingly, the relatively less-explored third metabolic pathway of AA exhibits both pro-proliferative and anti-apoptotic effects in endothelial cells and smooth muscle cells. Recent studies have shown elevated levels of EETs catalyzed by CYP epoxygenases in human tumors, promoting tumor progression and metastasis-phenomena closely related to the disease progression in pulmonary hypertension (PH). This review explores the current understanding of the regulatory functions of CYP-derived EETs in cardiovascular diseases and seeks to elucidate their potential implications in PH. Ultimately, understanding the multifaceted roles of EETs may help identify novel therapeutic targets for both cardiovascular diseases and PH., Competing Interests: Declarations.

- Abstract
The stems and leaves of submerged macrophytes usually grow below the water surface and could provide a good biological carrier for the colonization and growth of planktonic bacteria in water. Therefore, attached bacteria on the stem and leaf surfaces of submerged macrophytes are important components and play a crucial role in aquatic ecosystems. To further understand the structure characteristics and functional differences of the bacterial community attached to the stems and leaves of submerged macrophytes, the submerged macrophytes Potamogeton crispus and the overlying water and sediment were sampled and analyzed in this study. The results showed that a total of 10 320 OTUs were detected in the P. crispus samples, the overlying water samples, and the sediment samples. These OTUs included 64 phyla, 189 classes, 448 orders, 721 families, and 1 366 genera. The richness and diversity of bacterial communities in sediments were the highest, followed by the stem and leaves of P. crispus , and the alpha diversity index of planktonic bacteria in water was the lowest. Significant differences (P <0.05) were observed among the four alpha diversity indices of the three source samples. Bacterial communities with greater similarity were obtained from the same source samples, but there was more distinct community composition dissimilarity in bacteria collected from the submerged macrophytes and the overlying water and sediment samples ( P <0.05). At the level of phylum, order, and genus classification, the relative abundance of most dominant bacterial species, non-dominant species, and occasional species showed significant differences among the three source samples ( P <0.05). Proteobacteria, Actinobacteria, and Bacteroidetes were common dominant bacterial phyla for the three source samples, while Firmicutes were unique dominant phyla for attachment bacteria on the plant stem and leaves of P. crispus . There were differences in carbohydrate metabolism, energy metabolism, amino acid metabolism, cofactors, and vitamin metabolism among the three source samples ( P <0.05). The relative abundance of chemical heterotrophic and oxidative heterotrophic functional types in the stem and leaf samples of P. crispus was higher than that in the overlying water and sediment samples. In addition, higher nitrate reduction, nitrogen respiration, and nitric acid respiration functions were observed in sediment samples. To summarize, the stems and leaves have the potential to encourage bacterial colonization and create a unique bacterial community on the surface of submerged macrophytes. Submerged P. crispus macrophytes and their surroundings (water and sediment) play different roles in the biogeochemical cycling of nutrients in the freshwater ecosystem.

- Abstract
Objective: This study aims to explore the effects of Triptolide (TP) on the differentiation of Th17 cells in ankylosing spondylitis (AS)., Methods: Peripheral blood mononuclear cells (PBMCs) collected from 10 patients with active AS patients were exposed to TP, GSK-J4 or vehicle. T lymphocyte subsets were analyzed using flow cytometry. ELISA was used to assess the level of IL-17. Western blot analysis and quantitative RT-PCR were used to measure the mRNA and protein levels of RORγt, JMJD3, EZH2, JAK2 and STAT3 in the JAK2/STAT3 signaling pathway., Results: We observed a tendency toward a greater percentage of IL-17-positive CD4+ T cells in peripheral blood mononuclear cells (PBMCs) from patients with active AS than in those from healthy controls. Triptolide (TP) and GSK-J4 significantly reduced IL-17 expression. In cultured PBMCs from patients with active AS, 24 h of treatment with TP or GSK-J4 decreased the expression of RORγt ( p < 0.05), JAK2 and STAT3 (JAK2: p < 0.05; STAT3: p < 0.05). Furthermore, both triptolide and GSK-J4 increased the level of histone 3 with Lys 27 trimethylation (H3K27me3) in patient-derived PBMCs. H3K27me3 enrichment was detected at the promoters of the RORc, STAT3 and IL-17 genes. Consistent with this finding, triptolide upregulated the EZH2 gene and downregulated the JMJD3 gene., Conclusion: Triptolide inhibits Th17 cell differentiation via H3K27me3 upregulation and orchestrates changes in histone-modifying enzymes, including JMJD3 and EZH2. These findings support the clinical efficacy of triptolide for AS and may provide clues for identifying molecular targets for the development of novel treatments.

- Abstract
Background: Intracerebral hemorrhage (ICH) stands out as the most fatal subtype of stroke, currently devoid of effective therapy. Recent research underscores the significance of Axl and its ligand growth arrest-specific 6 (Gas6) in normal brain function and a spectrum of neurological disorders, including ICH. This study is designed to delve into the role of Gas6/Axl signaling in facilitating hematoma clearance and neuroinflammation resolution following ICH., Methods: Adult male C57BL/6 mice were randomly assigned to sham and ICH groups. ICH was induced by intrastriatal injection of autologous arterial blood. Recombinant mouse Gas6 (rmGas6) was administered intracerebroventricularly 30 min after ICH. Virus-induced knockdown of Axl or R428 (a selective inhibitor of Axl) treatment was administrated before ICH induction to investigate the protective mechanisms. Molecular changes were assessed using western blot, enzyme-linked immunosorbent assay and immunohistochemistry. Coronal brain slices, brain water content and neurobehavioral tests were employed to evaluate histological and neurofunctional outcomes, respectively. Primary glia cultures and erythrophagocytosis assays were applied for mechanistic studies., Results: The expression of Axl increased at 12 h after ICH, peaking on day 3. Gas6 expression did not remarkably changed until day 3 post-ICH. Early administration of rmGas6 following ICH significantly reduced hematoma volume, mitigated brain edema, and restored neurological function. Both Axl-knockdown and Axl inhibitor treatment abolished the neuroprotection of exogenous Gas6 in ICH. In vitro studies demonstrated that microglia exhibited higher capacity for phagocytosing eryptotic erythrocytes compared to normal erythrocytes, a process reversed by blocking the externalized phosphatidylserine on eryptotic erythrocytes. The erythrophagocytosis by microglia was Axl-mediated and Gas6-dependent. Augmentation of Gas6/Axl signaling attenuated neuroinflammation and drove microglia towards pro-resolving phenotype., Conclusions: This study demonstrated the beneficial effects of recombinant Gas6 on hematoma resolution, alleviation of neuroinflammation, and neurofunctional recovery in an animal model of ICH. These effects were primarily mediated by the phagocytotic role of Axl expressed on microglia., Competing Interests: Declaration of competing interest The authors declare that they have no competing interest., (Copyright © 2024 Elsevier Inc.

- Abstract
Decidual macrophages are the second-largest immune cell group at the maternal-foetal interface. They participate in apoptotic cell removal, and protect the foetus from microorganisms or pathogens. Dysfunction of decidual macrophages gives rise to pregnancy complications such as preeclampsia and recurrent spontaneous miscarriage (RSM). However, the mechanisms by which decidual macrophages are involved in the occurrence of adverse pregnancy outcomes have not been elucidated. Here we integrated DNA methylation and gene expression data from decidua macrophages to identify potential risk factors related to RSM. GPR133 was significantly hypomethylated and upregulated in decidual macrophages from RSM patients. Further demethylation analysis demonstrated that GPR133 expression in decidual macrophages was significantly increased by 5-Aza-dC treatment. In addition, the influence of GPR133 on the phagocytic ability of macrophages was explored. Phagocytosis was impaired in the decidual macrophages of RSM patients with increased GPR133 expression. Increased GPR133 expression induced by demethylation treatment in the decidual macrophages of healthy control patients led to a significant decrease in phagocytic function. Importantly, knockdown of GPR133 resulted in a significant improvement in the phagocytic function of THP-1 macrophages. In conclusion, the existing studies have shown the influence of GPR133 on the phagocytic function of decidual macrophages and pregnancy outcomes, providing new data and ideas for future research on the role of decidual macrophages in RSM.

- Abstract
The orbitofrontal cortex (ORB), a region crucial for stimulus-reward association, decision-making, and flexible behaviors, extensively connects with other brain areas. However, brain-wide inputs to projection-defined ORB neurons and the distribution of inhibitory neurons postsynaptic to neurons in specific ORB subregions remain poorly characterized. Here we mapped the inputs of five types of projection-specific ORB neurons and ORB outputs to two types of inhibitory neurons. We found that different projection-defined ORB neurons received inputs from similar cortical and thalamic regions, albeit with quantitative variations, particularly in somatomotor areas and medial groups of the dorsal thalamus. By counting parvalbumin (PV) or somatostatin (SST) interneurons innervated by neurons in specific ORB subregions, we found a higher fraction of PV neurons in sensory cortices and a higher fraction of SST neurons in subcortical regions targeted by medial ORB neurons. These results provide insights into understanding and investigating the function of specific ORB neurons., Competing Interests: Conflict of interest: The authors declare that there are no conflicts of interest., (© 2024.

- Abstract
The coordination of forelimb and orofacial movements to compose an ethological reach-to-consume behavior likely involves neural communication across brain regions. Leveraging wide-field imaging and photo-inhibition to survey across the cortex, we identified a cortical network and a high-order motor area (MOs-c), which coordinate action progression in a mouse reach-and-withdraw-to-drink (RWD) behavior. Electrophysiology and photo-inhibition across multiple projection neuron types within the MOs-c revealed differential contributions of pyramidal tract and corticothalamic (CT
MOs ) output channels to action progression and hand-mouth coordination. Notably, CTMOs display sustained firing throughout RWD sequence and selectively enhance RWD-relevant activity in postsynaptic thalamus neurons, which also contribute to action coordination. CTMOs receive converging monosynaptic inputs from forelimb and orofacial sensorimotor areas and are reciprocally connected to thalamic neurons, which project back to the cortical network. Therefore, motor cortex corticothalamic channel may selectively amplify the thalamic integration of cortical and subcortical sensorimotor streams to coordinate a skilled motor sequence., Competing Interests: DECLARATION OF INTERESTS The authors declare no competing interests.- Published

- Abstract
Background: The relationship between the dynamic changes in insulin resistance (IR) and the prognosis of septic patients remains unclear. This study aims to investigate the correlation between the clinical subphenotype of IR represented by the triglyceride-glucose (TyG) index trajectory and the mortality rate among patients with sepsis., Methods: In this retrospective cohort study, we utilized data from septic patients within the Medical Information Mart for Intensive Care (MIMIC)-IV database version 2.0 to construct trajectories of the TyG index over 72 h. Subsequently, we computed the similarity among various TyG index trajectories with the dynamic time warping (DTW) algorithm and utilized the hierarchical clustering (HC) algorithm to demarcate distinct cluster and identified subphenotypes according to the trajectory trend. Subsequently, we assessed the mortality risk between different subphenotypes using analyses such as survival analysis and validated the robustness of the results through propensity score matching (PSM) and various models., Results: A total of 2350 patients were included in the study. Two trajectory trends: TyG index decreasing (n = 926) and TyG index increasing (n = 1424) were identified, which indicated corresponding to the clinical subphenotype of increased and alleviative IR respectively. The 28-day and in-hospital mortality for the increased IR group was 28.51% and 25.49% respectively. In comparison, patients in the alleviative IR group with a 28-day mortality of 23.54% and an in-hospital mortality of 21.60%. These subphenotypes exhibited distinct prognosis, time dependent Cox model showed the increased IR group with a higher 28-day mortality [hazard ratio (HR): 1.07, 95% confidence interval (CI): 1.02-1.12, P = 0.01] and in-hospital mortality [HR: 1.05, 95% CI: 1.00-1.11, P = 0.045] compared to the alleviative IR group. Sensitivity analyses with various models further validated the robustness of our findings., Conclusion: Dynamic increase in the TyG index trajectory is associated with elevated mortality risk among patients with sepsis, which suggests that dynamic increased IR exacerbates the risk of poor outcomes in patients., (© 2024.

The BG trajectory subphenotypes were identified using the hierarchical clustering based on the dynamic time-warping algorithm. The primary outcome of the study was 28-day mortality, with secondary outcomes including 180-day and 1-year mortality., Results: We screened a total of 21,098 HF patients and finally 15,092 patients were included in the study. Our results identified three distinct BG trajectory subphenotypes: increasing (n = 3503), stabilizing (n = 6250), and decreasing (n = 5339). The increasing subphenotype was associated with the highest mortality risk at 28 days, 180 days, and 1 year. The stabilizing and decreasing subphenotypes showed significantly lower mortality risks across all time points, with hazard ratios ranging from 0.85 to 0.88 (P<0.05 for all). Sensitivity analyses confirmed the robustness of these findings after adjusting for various covariates., Conclusions: Increasing BG trajectory within 48 h of admission is significantly associated with higher mortality in patients with HF. It is necessary to devote greater attention to the early BG dynamic changes in HF patients to optimize clinical BG management and enhance patient prognosis., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

- Abstract
We elucidated the changes of soil microbial biomass and community structure in soil profiles under four typical land use types (farmland, grassland, Betula platyphylla secondary forest and Larix principis-rupprechtii plantation)and across five soil layers (0-10, 10-20, 20-30, 30-40, 40-50 cm) in the northern mountainous region of Hebei Province. We measured soil microbial biomass by phospholipid fatty acid (PLFA) method, and investigated the effects of land use and soil depth on soil microbial biomass and community structure by variance analysis, correlation analysis and redundancy analysis. The results showed that soil water content, bulk density, and organic carbon content of farmland differed significantly from other land use types. The content of PLFA in farmland was significantly lower than that in other land use types. The Gram-positive bacteria/Gram-negative bacteria (G
+ /G- ) in farmland were higher, and the nutrient stress was greater. With the increase of soil depth, soil water content, organic carbon, total nitrogen, total phosphorus and microbial biomass of the four land use types showed a decreasing trend. In grassland, secondary forest and plantation, G+ /G- was larger in deep soil than top soil. Except for grassland, the bacteria/fungi was smaller in deep soil than top soil. Correlation analysis and redundancy analysis showed that soil bulk density, natural water content and organic carbon were the main environmental factors affecting microbial communities in the four land use types. Our results would provide theoretical basis for the optimization of land use structure in the northern mountainous region of Hebei Province.- Published

- Abstract
Rifaximin and rifampicin are good broad-spectrum antimicrobials. The irrational use of antimicrobial drugs in veterinary clinics could threaten public health and food safety. It is necessary to develop a reliable detection method of the residue for enhancing the rational supervision of the use of such drugs, reducing and slowing down the generation of bacterial resistance, and promoting animal food safety and human health. So, this study developed an LC-MS/MS method for the detection of rifaximin and rifampicin residues in animal-origin foods. The residual rifaximin and rifampicin of homogenized test materials were extracted with acetonitrile-dichloromethane solution or acetonitrile in the presence of anhydrous sodium sulfate and vitamin C, purified by dispersible solid phase extraction, determined by LC-MS/MS, and quantified by the internal standard method. The specificity, sensitivity, matrix effect, accuracy, and precision of the method were investigated in the edible tissues of cattle, swine, or chicken. In addition, the stability of the standard stock solution and the standard working solution was also investigated. The method was suitable for the muscle, liver, kidney, fat, milk, and eggs of cattle, swine, or chicken, as well as fish and shrimp. The specificity of the method was good, and the detection of the analytes was not affected by different matrices. Both the LOD and LOQ of the two analytes were 5 μg/kg and 10 μg/kg, respectively. The results of matrix effects in each tissue were in the range of 80-120%; there were no significant matrix effects. The average accuracy of rifaximin and rifampicin in different foodstuffs of animal origin was between 80% and 120%, and the method precision was below 20% (RSD). The proposed method showed good performance for determination, which could be employed for the extraction, purification, and detection of residual rifaximin and rifampicin in edible animal tissues. The pretreatment procedure of tissue samples was simple and feasible. The method was highly specific, stable, reliable, and with high sensitivity, accuracy, and precision, which met the requirements of quantitative detection of veterinary drug residues.

- Abstract
Objective: We aimed to analyse the trend of incidence and mortality of stomach cancer in Shandong province from 2012 to 2022 and predict the development trend from 2023 to 2030. Methods: Data on incidence and mortality of stomach cancer in Shandong province from 2012 to 2022 were obtained from Shandong Cancer Registry. The incidence, age-specific incidence, mortality and age-specific mortality in different years, sexes and urban and rural areas were calculated, the rates were standardized based on the age composition of the Chinese standard population in 2000. The average annual percent change (AAPC) of incidence and mortality was calculated using Joinpoint software. The Bayesian age-period-cohort model was used to predict the trend of stomach cancer incidence and mortality from 2023 to 2030. Results: From 2012 to 2022, the stomach cancer age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) showed a decreasing trend. The ASIR decreased from 27.47/100 000 in 2012 to 16.06/100 000 in 2022 (AAPC=-5.10%, P <0.001), and the ASMR decreased from 17.69/100 000 to 11.09/100 000 (AAPC=-5.52%, P <0.001). The ASIR and ASMR of male, female, urban and rural population also showed downward trends. The incidence and mortality rates of men were always higher than those of women, and the difference between urban and rural areas is gradually narrowing. In 2022, the ASIR (16.09/100 000 in urban and 16.03/100 000 in rural) and the ASMR (11.10/100 000 in urban and 11.08/100 000 in rural) of stomach cancer between urban and rural areas were nearly identical. The Bayesian age-period-cohort model predicted that the ASIR of stomach cancer in Shandong would further decrease from 2023 to 2030 (AAPC=-0.51%, P =0.001), but the change tended to be smooth. The incidences in male (AAPC=-1.46%, P= 0.010) and rural areas (AAPC=-1.21%, P <0.001) were still expected to have a little room for decline. The trend of incidences in female and urban areas were not statistically significant. The trend of mortality was consistent with the incidence. Conclusions: The stomach cancer incidence and mortality in Shandong shows a decreasing trend and it is expected to decrease further by 2030. However, the trend tends to be smooth, and the disease burden should be reduced as early as possible for high-risk population and high-risk factors of stomach cancer.

- Abstract
Background: Parkinson's disease (PD) is a prevalent disorder of the central nervous system, marked by the degeneration of dopamine (DA) neurons in the ventral midbrain. In the pathogenesis of PD, inflammation hypothesis has been concerned. This study aims to investigate clinical indicators of peripheral inflammation in PD patients and to explore the diagnostic value of neutrophil-to-lymphocyte ratio (NLR), albumin-to-fibrinogen ratio (AFR), and lymphocyte-to-monocyte ratio (LMR) in assessing PD risk., Methods: This study included 186 patients with PD and 201 matched healthy controls (HC) with baseline data. Firstly, the differences of hematological indicators between PD group and healthy participants were compared and analyzed. Univariate and multivariate regression analyses were then conducted. Smooth curve fitting was applied to further validate the relationships between NLR, LMR, AFR, and PD. Subsequently, subgroup analysis was conducted in PD group according to different duration of disease and Hoehn and Yahr (H&Y) stage, comparing differences in clinical indicators. Finally, the receiver operating characteristic (ROC) curve was employed to assess the diagnostic value of NLR, LMR, and AFR in PD., Results: Compared to the HC group, the PD group showed significantly higher levels of hypertension, diabetes, neutrophil count, monocyte count, CRP, homocysteine, fibrinogen, and NLR. Conversely, levels of LMR, AFR, lymphocyte count, HDL, LDL, TG, TC, uric acid, and albumin were significantly lower. The multivariate regression model indicated that NLR (OR = 1.79, 95% CI: 1.39-2.31, p < 0.001), LMR (OR = 0.75, 95% CI: 0.66-0.85, p < 0.001), and AFR (OR = 0.79, 95% CI: 0.73-0.85, p < 0.001) were significant factors associated with PD. Smooth curve fitting revealed that NLR was positively linked to PD risk, whereas AFR and LMR were inversely associated with it. In ROC curve analysis, the AUC of AFR was 0.7290, the sensitivity was 63.98%, and the specificity was 76.00%. The AUC of NLR was 0.6200, the sensitivity was 50.54%, and the specificity was 71.50%. The AUC of LMR was 0.6253, the sensitivity was 48.39%, and the specificity was 73.00%. The AUC of the combination was 0.7498, the sensitivity was 74.19%, and the specificity was 64.00%., Conclusion: Our findings indicate that NLR, LMR, and AFR are significantly associated with Parkinson's disease and may serve as diagnostic markers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Li, Xu, Ren, Xu, Dai, Yang and Jin.)

- Abstract
Prostate cancer (PCa) is the second most prevalent malignancy among men worldwide. The aberrant activation of androgen receptor (AR) signaling has been recognized as a crucial oncogenic driver for PCa and AR antagonists are widely used in PCa therapy. To develop novel AR antagonist, a machine-learning MIEC-SVM model was established for the virtual screening and 51 candidates were selected and submitted for bioactivity evaluation. To our surprise, a new-scaffold AR antagonist C2 with comparable bioactivity with Enz was identified at the initial round of screening. C2 showed pronounced inhibition on the transcriptional function (IC
50 = 0.63 μM) and nuclear translocation of AR and significant antiproliferative and antimetastatic activity on PCa cell line of LNCaP. In addition, C2 exhibited a stronger ability to block the cell cycle of LNCaP than Enz at lower dose and superior AR specificity. Our study highlights the success of MIEC-SVM in discovering AR antagonists, and compound C2 presents a promising new scaffold for the development of AR-targeted therapeutics., (© 2024.

- Abstract
Cluster headache (CH) is a common primary headache that severely impacts patients' quality of life, characterized by recurrent, severe, unilateral headaches often centered around the eyes, temples, or forehead. Distinguishing CH from other headache disorders is challenging, and its pathogenesis remains unclear. Notably, patients with CH often experience high levels of depression and suicidal tendencies, necessitating increased clinical attention. This comprehensive assessment combines various reports and the latest scientific literature to evaluate the current state of CH research. It covers epidemiology, population characteristics, predisposing factors, and treatment strategies. Additionally, we provide strategic insights into the holistic management of CH, which involves continuous, individualized care throughout the prevention, treatment, and rehabilitation stages. Recent advances in the field have revealed new insights into the pathophysiology of CH. While these findings are still evolving, they offer a more detailed understanding of the neurobiological mechanisms underlying this disorder. This growing body of knowledge, alongside ongoing research efforts, promises to lead to the development of more targeted and effective treatments in the future., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Xu, Li, Ren, Xu, Dai, Jin and Yang.)

- Abstract
Aesthetic education, conveyed through public art courses, serves as a vital form of humanistic literacy education. It represents an effective approach to fostering innovative and creative thinking among college students. In order to effectively analyze the aesthetic education work of 46 universities, an aesthetic education index evaluation system is constructed, involving indicators including faculty strength, curriculum setting, teaching management, artistic practice, and teaching support. The secondary indicators corresponding to the five indicators are statistically analyzed, and a comprehensive evaluation analysis of the current development status of aesthetic education in 46 universities in Anhui Province is conducted by combining theoretical analysis with empirical analysis. Based on principal component analysis, an integrated evaluation model for the development of aesthetic education in universities in Anhui Province is further constructed. The model designed quantifies the influence weight of each aesthetic education index on the development of aesthetic education in Anhui Province, and forges a theoretical basis for determining the precursors of rapid development of aesthetic education in Anhui Province. Additionally, a novel approach is introduced to gauge the progression of aesthetic education within universities in Anhui Province, considering the dispersion of aesthetic education index data across the province. The comprehensive evaluation model for the development of aesthetic education in Anhui Province exhibits an overall declining trend. Hence, it is suggested to utilize the maximum value of the first derivative of the comprehensive evaluation model as an indicator of the imminent rapid development of aesthetic education in Anhui Province. On this basis, the probability equation of sustainable development of aesthetic education in Anhui Province is defined. Overall, the research results lay a theoretical foundation for the development of aesthetic education in Anhui Province., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Xu et al.

- Abstract
Background: Idiopathic pulmonary fibrosis (IPF) is classified under fibrotic interstitial pneumonia, characterized by a chronic and progressive course. The predominant clinical features of IPF include dyspnea and pulmonary dysfunction., Aim: To assess the effects of pirfenidone in the early treatment of IPF on lung function in patients., Methods: A retrospective analysis was performed on 113 patients with IPF who were treated in our hospital from November 2017 to January 2023. These patients were divided into two groups: control group ( n = 53) and observation group ( n = 60). In the control group, patients received routine therapy in combination with methylprednisolone tablets, while those in the observation group received routine therapy together with pirfenidone. After applying these distinct treatment approaches to the two groups, we assessed several parameters, including the overall effectiveness of clinical therapy, the occurrence of adverse reactions ( e.g., nausea, vomiting, and anorexia), symptom severity scores, pulmonary function index levels, inflammatory marker levels, and the 6-min walk distance before and after treatment in both groups., Results: The observation group exhibited significantly higher rates than the control group after therapy, with a clear distinction ( P < 0.05). After treatment, the observation group experienced significantly fewer adverse reactions than the control group, with a noticeable difference ( P < 0.05). When analyzing the symptom severity scores between the two groups of patients after treatment, the observation group had significantly lower scores than the control group, with a distinct difference ( P < 0.05). When comparing the pulmonary function index levels between the two groups of patients after therapy, the observation group displayed significantly higher levels than the control group, with a noticeable difference ( P < 0.05). Evaluating the inflammatory marker data (C-reactive protein, interleukin-2 [IL-2], and IL-8) between the two groups of patients after therapy, the observation group exhibited significantly lower levels than the control group, with significant disparities ( P < 0.05). Comparison of the 6-min walking distance data between the two groups of patients after treatment showed that the observation group achieved significantly greater distances than the control group, with a marked difference ( P < 0.05)., Conclusion: Prompt initiation of pirfenidone treatment in individuals diagnosed with IPF can enhance pulmonary function, elevate inflammatory factor levels, and increase the distance covered in the 6-min walk test. This intervention is conducive to effectively decreasing the occurrence of adverse reactions in patients., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest to declare., (©The Author(s) 2024.

- Abstract
Background: circRNAs have been shown to participate in diverse diseases; however, their role in oral submucous fibrosis (OSF), a potentially malignant disorder, remains obscure. Our preliminary experiments detected the expression of circRNA mitochondrial translation optimization 1 homologue (circMTO1) in OSF tissues (n = 20) and normal mucosa tissues (n = 20) collected from Hunan Xiangya Stomatological Hospital, and a significant decrease of circMTO1 expression was showed in OSF tissues. Therefore, we further explored circMTO1 expression in OSF., Methods: Target molecule expression was detected using RT-qPCR and western blotting. The migration and invasion of buccal mucosal fibroblasts (BMFs) were assessed using wound healing and Transwell assays. The interaction between miR-30c-5p, circMTO1, and SOCS3 was evaluated using dual luciferase, RNA immunoprecipitation (RIP), and RNA pull-down assays. The colocalisation of circMTO1 and miR-30c-5p was observed using fluorescence in situ hybridisation (FISH)., Results: circMTO1 and SOCS3 expression decreased, whereas miR-30c-5p expression increased in patients with OSF and arecoline-stimulated BMFs. Overexpression of circMTO1 effectively restrained the fibroblast-myofibroblast transition (FMT), as evidenced by the increase in expression of Coll I, α-SMA, Vimentin, and the weakened migration and invasion functions in BMFs. Mechanistic studies have shown that circMTO1 suppresses FMT by enhancing SOCS3 expression by sponging miR-30c-5p and subsequently inactivating the FAK/PI3K/AKT pathway. FMT induced by SOCS3 silencing was reversed by the FAK inhibitor TAE226 or the PI3K inhibitor LY294002., Conclusion: circMTO1/miR-30c-5p/SOCS3 axis regulates FMT in arecoline-treated BMFs via the FAK/PI3K/AKT pathway. Expanding the sample size and in vivo validation could further elucidate their potential as therapeutic targets for OSF., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

- Abstract
Background: The contrasted-enhanced ultrasound thyroid imaging reporting and data system (CEUS TI-RADS) is the first international risk stratification system for thyroid nodules based on conventional ultrasound (US) and CEUS. This study aimed to evaluate the diagnostic efficacy of CEUS TI-RADS for benign and malignant thyroid nodules and to assess the related interobserver agreement., Methods: The study recruited 433 patients who underwent thyroid US and CEUS between January 2019 and June 2023 at the Affiliated Hospital of Guangdong Medical University. A retrospective analysis of 467 thyroid nodules confirmed by fine-needle aspiration (FNA) and/or surgery was performed. Further, a CEUS TI-RADS classification was assigned to each thyroid nodule based on the CEUS TI-RADS scoring criteria for the US and CEUS features of the nodule. The nodules were grouped based on their sizes as follows: size ≤1 cm, group A; size >1 and ≤4 cm, group B; and size >4 cm, group C. Multivariate logistic regression was used to analyze independent risk factors for malignant thyroid nodules. Pathological assessment was the reference standard for establishing the sensitivity (SEN), specificity (SPE), accuracy (ACC), positive predictive value (PPV), and negative predictive value (NPV) of CEUS TI-RADS in diagnosing malignant thyroid nodules. The area under the curve (AUC) in the receiver operating characteristic (ROC) curve analysis was used to compare the diagnostic efficacy of the scoring system in predicting malignancy in three groups of nodules. The intragroup correlation coefficient (ICC) was adopted to assess the interobserver agreement of the CEUS TI-RADS score., Results: Out of the 467 thyroid nodules, 262 were malignant and 205 were benign. Logistic regression analysis revealed that the independent risk factors for malignant thyroid nodules included punctate echogenic foci (P<0.001), taller-than-wide shape (P=0.015), extrathyroidal invasion (P=0.020), irregular margins/lobulation (P=0.036), hypoechoicity on US (P=0.038), and hypoenhancement on CEUS (P<0.001). The AUC for the CEUS TI-RADS in diagnosing malignant thyroid nodules was 0.898 for all nodules, 0.795 for group A, 0.949 for group B, and 0.801 for group C, with the optimal cutoff values of the CEUS TI-RADS being 5 points, 6 points, 5 points, and 5 points, respectively. Among these groups of nodules, group B had the highest AUC, with the SEN, SPE, ACC, PPV, and NPV for diagnosing malignant nodules being 95.9%, 88.1%, 92.8%, 92.6%, and 93.2%, respectively. The ICC of the CEUS TI-RADS classification between senior and junior physicians was 0.862 (P<0.001)., Conclusions: In summary, CEUS TI-RADS demonstrated significant efficacy in distinguishing thyroid nodules. Nonetheless, there were variations in its capacity to detect malignant nodules across diverse sizes, and it demonstrate optimal performance in 1- to 4-cm nodules. These findings may serve as important insights for clinical diagnoses., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://qims.amegroups.com/article/view/10.21037/qims-24-457/coif).

- Abstract
Studies investigating the relationship between dietary vitamin B1 intake and risk of Hyperuricemia (HU) are scarce, the present study aimed to examine the association of dietary vitamin B1 intake and HU among adults. This cross-sectional study included 5750 adults whose data derived from National Health and Nutrition Examination Survey (NHANES) from March 2017 to March 2020. The dietary intake of vitamin B1 was assessed using 24-h dietary recall interviews. The characteristics of study participants were grouped into five levels according to the levels of vitamin B1 quintile. Multivariate logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of HU, according to the vitamin B1 intake quintile for male and female separately. The dose-response relationship was determined by the restricted cubic spline (RCS). Smoothed curve fitting was used to assess serum uric acid concentration versus dietary vitamin B1 intake in the study population. The prevalence of hyperuricemia was 18.90% (20.15% and 17.79% for males and females, respectively) in the United States from March 2017 to March 2020. Multiple logistic regression analyses showed that in the male population, the HU ratio (OR) of vitamin B1 intake in Q2 to Q5 compared with the lowest quintile (Q1) was 0.75 (95% CI 0.52, 1.09), 0.70 (95% CI 0.48, 1.02), 0.66 (95% CI 0.44, 0.99) and 0.55 (95% CI 0.34, 0.90). The P for trend was 0.028. In women, the ORs for vitamin B1 intake Q2 to Q5 were 0.87 (95% CI 0.64, 1.19), 0.97 (0.68-1.38), 1.05 (0.69-1.60) and 0.75 (0.42-1.34), respectively. The P for trend was 0.876. The RCS curve revealed a linear relationship between vitamin B1 intake and the risk of hyperuricemia in men (P nonlinear = 0.401). Smoothed curve fitting demonstrated a negative association between vitamin B1 intake and serum uric acid concentration in men, whereas there was no significant association between dietary vitamin B1 intake and the risk of hyperuricemia in women. In the US adult population, dietary vitamin B1 intake was negatively associated with hyperuricemia in males., (© 2024. The Author(s).)

- Abstract
Porous materials have attracted interest due to their high specific surface area and rich functionality. Immobilizing organocatalysts onto porous polymers not only boosts enantioselectivity but also improves the reaction rates. In this work, a series of porous polymers C-poly-3
m s with rigid polyisocyanide-carrying secondary amine pendants as building blocks were successfully prepared. And the pore size and optical activity of C-poly-3m s can be controlled by the length of the polyisocyanide blocks due to their rigid and helical backbone. C-poly-3150 demonstrated a preferred left-handed helix with a θ364 value of -8.21 × 103 . The pore size and SBET of C-poly-3150 were 17.52 nm and 7.98 m2 g-1 , respectively. The porous C-poly-3150 catalyzes the asymmetric Michael addition reaction efficiently and generates the target products in satisfactory yield and excellent enantioselectivity. For 6ab, an enantiomeric excess (ee) and a diastereomeric ratio (dr) up to 99% and 99/1 could be achieved, respectively.

- Abstract
Pulmonary infection due to Mycobacterium abscessus complex (MABC) usually occurs in children with underlying risk factors including cystic fibrosis (CF), chronic lung disease, and immunocompromised status, but rarely in immunocompetent children without underlying lung disease, especially in infants. We present a case of MABC pulmonary disease (MABC-PD) in an otherwise healthy 53-day-old male infant with one week of cough and respiratory distress. Computed tomography showed multiple masses across both lungs. Isolated mycobacteria from his bronchoalveolar lavage fluid were identified as MABC. We describe our complete evaluation, including immunodeficiency evaluation incorporating whole exome sequencing and our therapeutic process given complicated susceptibility pattern of the M. abscessus isolate, and review literature for MABC-PD in immunocompetent children. The infant was successfully treated through prolonged treatment with parenteral Amikacin, Cefoxitin, Linezolid, and Clarithromycin, combined with inhaled Amikacin., Competing Interests: Declaration of competing interest No potential conflict of interest relevant to this article was reported., (Copyright © 2024 Elsevier Inc.

- Abstract
Background: Metastatic colorectal cancer (mCRC) is a common malignancy whose treatment has been a clinical challenge. Cancer-specific survival (CSS) plays a crucial role in assessing patient prognosis and treatment outcomes. However, there is still limited research on the factors affecting CSS in mCRC patients and their correlation., Aim: To predict CSS, we developed a new nomogram model and risk grading system to classify risk levels in patients with mCRC., Methods: Data were extracted from the United States Surveillance, Epidemiology, and End Results database from 2018 to 2023. All eligible patients were randomly divided into a training cohort and a validation cohort. The Cox proportional hazards model was used to investigate the independent risk factors for CSS. A new nomogram model was developed to predict CSS and was evaluated through internal and external validation., Results: A multivariate Cox proportional risk model was used to identify independent risk factors for CSS. Then, new CSS columns were developed based on these factors. The consistency index (C-index) of the histogram was 0.718 (95%CI: 0.712-0.725), and that of the validation cohort was 0.722 (95%CI: 0.711-0.732), indicating good discrimination ability and better performance than tumor-node-metastasis staging (C-index: 0.712-0.732). For the training set, 0.533, 95%CI: 0.525-0.540; for the verification set, 0.524, 95%CI: 0.513-0.535. The calibration map and clinical decision curve showed good agreement and good potential clinical validity. The risk grading system divided all patients into three groups, and the Kaplan-Meier curve showed good stratification and differentiation of CSS between different groups. The median CSS times in the low-risk, medium-risk, and high-risk groups were 36 months (95%CI: 34.987-37.013), 18 months (95%CI: 17.273-18.727), and 5 months (95%CI: 4.503-5.497), respectively., Conclusion: Our study developed a new nomogram model to predict CSS in patients with synchronous mCRC. In addition, the risk-grading system helps to accurately assess patient prognosis and guide treatment., Competing Interests: Conflict-of-interest statement: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as potential conflicts of interest., (©The Author(s) 2024.

- Abstract
Objective: To investigate the characteristics and trends of spontaneous subarachnoid hemorrhage (SAH) in Shandong province. Methods: In this study, SAH incidence data of residents from 2012 to 2021 were collected from the chronic disease monitoring information management system of Shandong province, including the basic information of outpatient, emergency or inpatient cases and out-of-hospital deaths (name, gender, ID number, address, etc.) and disease diagnosis information (disease diagnosis, date of onset, date of diagnosis, etc.). The crude incidence rate and age-standardized incidence rate were used as indicators to describe the incidence of SAH in different gender, age groups and regions (urban and rural areas). Joinpoint regression was used to analyze the variation of incidence rate and age by year. The rate difference decomposition method was used to estimate the contribution of population aging to the increase of SAH incidence. Global and local spatial autocorrelation analysis was performed using DeoDa 1.12 software. Results: From 2012 to 2021, a total of 11 629 cases of SAH were reported from 19 provincial monitoring sites in Shandong province. Among them, 54.11% (6 293 cases) were female and 91.87% (10 684 cases) were≥45 years old. The reported crude incidence rate increased from 5.26/100 000 to 9.50/100 000, with an average annual increase of 7.75% ( Z
trend =7.30, Ptrend <0.001), and the standardized incidence rate also showed an upward trend ( Ztrend =3.92, Ptrend =0.004). The crude incidence rate of women was higher than that of men in all years (all P values<0.05), and the standardized incidence rate of women was higher than that of men in all years except in 2012 and 2021 (all P values<0.05). In 2012, the crude incidence and standardized incidence of urban residents were lower than those in rural areas ( P <0.05); from 2013 to 2017, the urban incidence was higher than that in rural areas; and after 2018, the rural incidence exceeded the urban incidence again (all P values<0.05). The median age of onset of SAH increased from 61.9 years in 2012 to 67.2 years in 2021. The age of onset of SAH in men was lower than that in women in all years (all P <0.05), and there was no significant difference between urban and rural residents in most years ( P >0.05). The incidence of SAH increased with age ( Ptrend <0.001), with a low incidence reported in residents aged<45 years and a rapid increase in residents aged≥45 years. According to the seasonal decomposition, the incidence of SAH had three small peaks in January, March to May and October to November. From 2013 to 2021, the contribution of aging population to the increase of crude incidence of SAH increased from 27.86% to 43.68%. The global spatial autocorrelation analysis showed that the incidence of SAH was in an obvious spatial aggregation distribution (Moran's I >0, P <0.05). Local spatial autocorrelation analysis showed that the counties with high incidence were mainly concentrated in Dezhou City in northwest Shandong Province and Heze city in southwest Shandong province. Conclusions: The crude incidence rate of SAH in Shandong province is increasing, with spatial clustering and seasonal clustering. Residents aged 45 years and older, female residents, and rural residents are at high risk of developing SAH, so targeted prevention and control measures should be taken for high-incidence seasons, high-risk groups, and high-incidence clustered areas.- Published

- Abstract
Background: As research on diabetes continues to advance, more complex classifications of this disease have emerged, revealing the existence of special types of diabetes, and many of these patients are prone to misdiagnosis and underdiagnosis, leading to treatment delays and increased health care costs. The purpose of this study was to identify four causes of secondary diabetes., Case Summary: Secondary diabetes can be caused by various factors, some of which are often overlooked. These factors include genetic defects, autoimmune disorders, and diabetes induced by tumours. This paper describes four types of secondary diabetes caused by Williams-Beuren syndrome, Prader-Willi syndrome, pituitary adenoma, and IgG4-related diseases. These cases deviate significantly from the typical progression of the disease due to their low incidence and rarity, often leading to their neglect in clinical practice. In comparison to regular diabetes patients, the four individuals described here exhibited distinct characteristics. Standard hypoglycaemic treatments failed to effectively control the disease. Subsequently, a series of examinations and follow-up history confirmed the diagnosis and underlying cause of diabetes. Upon addressing the primary condition, such as excising a pituitary adenoma, providing glucocorticoid supplementation, and implementing symptomatic treatments, all patients experienced a considerable decrease in blood glucose levels, which were subsequently maintained within a stable range. Furthermore, other accompanying symptoms improved., Conclusion: Rare diseases causing secondary diabetes are often not considered in the diagnosis of diabetes. Therefore, it is crucial to conduct genetic tests, antibody detection and other appropriate diagnostic measures when necessary to facilitate early diagnosis and intervention through proactive and efficient management of the underlying condition, ultimately improving patient outcomes., Competing Interests: Conflict-of-interest statement: All the authors declare no conflicts of interest for this article., (©The Author(s) 2024.

- Abstract
Objectives: To elucidate the association between the anticancer activities of piperlongumine (PL) and its potential target, transient receptor potential melastatin 7 channel (TRPM7), in oral squamous cell carcinoma (OSCC)., Methods: The expression levels and electrical characteristics of TRPM7 as well as cell viability in response to various PL treatments were investigated in the OSCC cell line Cal27., Results: PL treatment resulted in a concentration- and time-dependent reduction in TRPM7 mRNA and protein expression in Cal27 cells. Furthermore, PL treatment inhibited TRPM7-like rectifying currents in Cal27 cells; however, this inhibition was less effective than that of the TRPM7 antagonist waixenicin A. Rapid perfusion and washout experiments revealed an immediate inhibitory effect of PL on TRPM7-like currents. The antagonistic effect of PL occurred within 1 min and was not completely reversed following washout. Notably, the extracellular Ca
2+ concentration still influenced PL-induced changes in the TRPM7-like current, indicating that PL can directly but gently antagonize the TRPM7 channel. Functional changes in TRPM7 correlated with the observed antiproliferative and cytotoxic effects of PL in Cal27 cells., Conclusions: These findings suggest that PL exhibits potent inhibitory effects on TRPM7 and exerts its anti-cancer effects by downregulating TRPM7 expression and antagonizing channel currents., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Japanese Association for Oral Biology.

- Abstract
Graphene-based warm uterus acupoint paste (GWUAP) is an emerging non-drug alternative therapy for the treatment of primary dysmenorrhea (PD), but the underlying mechanism is still unclear. SD female rats were randomly divided into control group, model group and treatment group to explore the mechanism of GWUAP in the treatment of PD. Combined with 16S rDNA and fecal metabolomics, the diversity of microbiota and metabolites in each group was comprehensively evaluated. In this study, GWUAP reduced the torsion score of PD model rats, improved the pathological morphology of uterine tissue, reduced the pathological damage score of uterine tissue, and reversed the expression levels of inflammatory factors, pain factors and sex hormones. The 16 S rDNA sequencing of fecal samples showed that the abundance of Lactobacillus in the intestinal flora of the model group decreased and the abundance of Romboutsia increased, while the abundance of Lactobacillus in the intestinal flora of the treatment group increased and the abundance of Romboutsia decreased, which improved the imbalance of flora diversity in PD rats. In addition, 32 metabolites related to therapeutic effects were identified by metabolomics of fecal samples. Moreover, there is a close correlation between fecal microbiota and metabolites. Therefore, the mechanism of GWUAP in the treatment of PD remains to be further studied., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wang, Li, Cao, Zhao, Xu, Chai, Zhang, Liu and Wang.)

- Abstract
Background: Intraductal papillary neoplasm of the bile duct (IPNB) is a premalignant biliary-type epithelial neoplasm with intraductal papillary or villous growth. Currently reported local palliative therapeutic modalities, including endoscopic nasobiliary drainage, stenting and biliary curettage, endoscopic biliary polypectomy, percutaneous biliary drainage, laser ablation, argon plasma coagulation, photodynamic therapy, and radiofrequency ablation to relieve mechanical obstruction are limited with weaknesses and disadvantages. We have applied percutaneous transhepatic cholangioscopy (PTCS)-assisted biliary polypectomy (PTCS-BP) technique for the management of IPNB including mucin-hypersecreting cast-like and polypoid type tumors since 2010., Aim: To assess the technical feasibility, efficacy, and safety of PTCS-BP for local palliative treatment of IPNB., Methods: Patients with mucin-hypersecreting cast-like or polypoid type IPNB and receiving PTCS-BP between September 2010 and December 2019 were included. PTCS-BP was performed by using a half-moon type snare with a soft stainless-steel wire, and the tumor was snared and resected with electrocautery. The primary outcome was its feasibility, indicated by technical success. The secondary outcomes were efficacy, including therapeutic success, curative resection, and clinical success, and safety., Results: Five patients (four with mucin-hypersecreting cast-like type and one with polypoid type IPNB) were included. Low- and high-grade intraepithelial neoplasia (HGIN) and recurrent IPNB with invasive carcinoma were observed in one, two, and two patients, respectively. Repeated cholangitis and/or obstructive jaundice were presented in all four patients with mucin-hypersecreting cast-like type IPNB. All five patients achieved technical success of PTCS-BP. Four patients (three with mucin-hypersecreting cast-like type and one with polypoid type IPNB) obtained therapeutic success; one with mucin-hypersecreting cast-like type tumors in the intrahepatic small bile duct and HGIN had residual tumors. All four patients with mucin-hypersecreting IPNB achieved clinical success. The patient with polypoid type IPNB achieved curative resection. There were no PTCS-BP-related serious adverse events., Conclusion: PTCS-BP appears to be feasible, efficacious, and safe for local palliative treatment of both mucin-hypersecreting cast-like and polypoid type IPNB., Competing Interests: Conflict-of-interest statement: Authors declare no conflict of Interest for this article., (©The Author(s) 2024.

- Abstract
This study aims to investigate the mechanism of total saponins of Paridis Rhizoma in inducing the ferroptosis of MCF-7 cells and provide a theoretical basis for the clinical treatment of breast cancer with total saponins of Paridis Rhizoma. The methyl thiazolyl tetrazolium(MTT) assay was employed to examine the effects of different concentrations of total saponins of Paridis Rhizoma on the proliferation of MCF-7 cells. A phase contrast inverted microscope was used to observe the morphological changes of MCF-7 cells. The colony formation assay was employed to test the colony formation of MCF-7 cells. The lactate dehydrogenase(LDH) release test was conducted to determine the cell membrane integrity of MCF-7 cells. The cell scratch assay was employed to examine the migration of MCF-7 cells. After that, the level of reactive oxygen species(ROS) in MCF-7 cells was observed by an inverted fluorescence microscope, and the content of Fe~(2+) in MCF-7 cells was detected by the corresponding kit. Transmission electron microscopy was employed to observe the mitochondrial ultrastructure of MCF-7 cells. Western blot was employed to determine the expression of ferroptosis-related proteins, such as p53, solute carrier family 7 member 11(SLC7A11), glutathione peroxidase 4(GPX4), acyl-CoA synthetase long-chain family member 4(ACSL4), and transferrin receptor protein 1(TFR1) in MCF-7 cells. The results showed that 1.5, 3, 4.5, 6, 7.5, and 9 μg·mL~(-1) total saponins of Paridis Rhizoma significantly inhibited the proliferation of MCF-7 cells, with the IC_(50) of 4.12 μg·mL~(-1). Total saponins of Paridis Rhizoma significantly damaged the morphology of MCF-7 cells, leading to the formation of vacuoles and the gradual shrinkage and detachment of cells. Meanwhile, total saponins of Paridis Rhizoma inhibited the colony formation of MCF-7 cells, destroyed the cell membrane(leading to the release of LDH), and shortened the migration distance of MCF-7 cells. Total saponins of Paridis Rhizoma treatment significantly increased the content of ROS, induced oxidative damage, and led to the accumulation of Fe~(2+) in MCF-7 cells. Furthermore, total saponins of Paridis Rhizoma changed the mitochondrial structure, increased the mitochondrial membrane density, led to the decrease or even disappear of ridges, promoted the expression of p53 protein, down-regulated the expression of SLC7A11 and GPX4, and up-regulated the expression of ACSL4 and TFR1. In summary, total saponins of Paridis Rhizoma can significantly inhibit the proliferation and migration of MCF-7 cells and destroy the cell structure by inducing ferroptosis.

- Abstract
Bisboronic esters are critical compounds in various research fields, including drug discovery, chemical biology, and material sciences. Currently, the bisboronic esters with reactive functional groups are difficult to synthesize; this is partially due to the lack of a robust method to produce these products with diverse structures and various functional groups at specific locations. To overcome this issue, this study introduced a Ni-catalysis approach to produce bisboronic esters efficiently via cross-coupling and homocoupling using readily available halogenated boronic esters as the starting material under mild reaction conditions. This newly developed strategy enables Csp
2 -Csp2 , Csp3 -Csp3 , and Csp2 -Csp3 couplings, demonstrating a broad substrate scope and excellent compatibility with various functional groups.- Published

- Abstract
To cope with the damage from oxidative stress caused by hypoxia, mammals have evolved a series of physiological and biochemical traits, including antioxidant ability. Although numerous research studies about the mechanisms of hypoxia evolution have been reported, the molecular mechanisms of antioxidase-related genes in mammals living in different environments are yet to be completely understood. In this study, we constructed a dataset comprising 7 antioxidase-related genes ( CAT , SOD1 , SOD2 , SOD3 , GPX1 , GPX2 , and GPX3 ) from 43 mammalian species to implement evolutionary analysis. The results showed that six genes ( CAT , SOD1 , SOD2 , SOD3 , GPX1 , and GPX3 ) have undergone divergent evolution based on the free-ratio (M1) model. Furthermore, multi-ratio model analyses uncovered the divergent evolution between hypoxic and non-hypoxic lineages, as well as various hypoxic lineages. In addition, the branch-site model identified 9 positively selected branches in 6 genes ( CAT , SOD1 , SOD2 , SOD3 , GPX2 , and GPX3 ) that contained 35 positively selected sites, among which 31 positively selected sites were identified in hypoxia-tolerant branches, accounting for 89% of the total number of positively selected sites. Interestingly, 65 parallel/convergent sites were identified in the 7 genes. In summary, antioxidase-related genes are subjected to different selective pressures among hypoxia-tolerant species living in different habitats. This study provides a valuable insight into the molecular evolution of antioxidase-related genes in hypoxia evolution in mammals., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wang, Luo, Xu, Hu, Gai, Gong and Mu.)

- Abstract
Background: Bactrian camel is one of the important economic animals in northwest China. They live in arid desert, and their gestation period is about 13 months, which is longer than other ruminants (such as cattle and sheep). The harsh living conditions have made its unique histological characteristics a research focus. Aggregated lymphoid nodules area (ALNA) in the abomasum of Bactrian camels, as one of the most important sites for the induction of the immune response, provide a comprehensive and effective protective role for the organism, and their lack of information will affect the feeding management, reproduction and epidemic prevention of Bactrian camels. In this study, the histological characteristics of the fetal ALNA in the abomasum of Bactrian camels at different developmental gestation have been described by using light microscopy and histology ., Results: The ALNA in the abomasum of the Chinese Alashan Bactrian camel is a special immune structure that was first discovered and reported by Wen-hui Wang. To further establish the developmental characteristics of this special structure in the embryonic stage, the abomasum ALNA of 8 fetuses of Alashan Bactrian camels with different gestational ages (5~13 months) were observed and studied by anatomy and histology. The results showed that the aggregation of reticular epithelial cells (RECs) surrounded by a very small number of lymphoid cells was detected for the first time in the abomasum of fetal camel at 5 months gestation, which was presumed to be primitive ALNA. At 7 months gestation, the reticular mucosal folds region (RMFR) appeared, but the longitudinal mucosal folds region (LMFR) was not significant, and histological observations showed that there were diffusely distributed lymphocytes around the RECs. At 10months gestation, RMFR and LMFR were clearly visible, lymphoid follicles appeared in histological observation, lymphocytes proliferated vigorously. By 13 months, the volume of lymphoid follicles increased, forming the subepithelial dome (SED), and there was a primitive interfollicular area between the lymphoid follicles, which contained high endothelial vein (HEV), but no germinal center (GC) was found. In summary, ALNA of Bactrian camels is not fully mature before birth., Conclusions: Generally, the small intestine PPs of ruminants (such as cattle and sheep) is already mature before birth, while the ALNA in the abomasum of Bactrian camels is not yet mature in the fetal period. During the development of ALNA in Bactrian camel, the development of lymphoid follicles extends from submucosa to Lamina propria. Interestingly, the deformation of FAE changes with age from simple columnar epithelium at the beginning of pregnancy to Simple cuboidal epithelium, which is opposite to the FAE deformation characteristics of PPs in the small intestine of fetal cattle and sheep. These results are the basis of further research on the specificity of ALNA in the abomasum of Bactrian camels., (© 2024. The Author(s).)

- Abstract
DNA is susceptible to various factors in vitro and in vivo and experience different forms of damage,among which double-strand break(DSB)is a deleterious form.To maintain the stability of genetic information,organisms have developed multiple mechanisms to repair DNA damage.Among these mechanisms,homologous recombination(HR)is praised for the high accuracy.The MRE11-RAD50-NBS1(MRN)complex plays an important role in HR and is conserved across different species.The knowledge on the MRN complex mainly came from the previous studies in Saccharomyces cerevisiae and Caenorhabditis elegans ,while studies in the last decades have revealed the role of mammalian MRN complex in DNA repair of higher animals.In this review,we first introduces the MRN complex regarding the composition,structure,and roles in HR.In addition,we discuss the human diseases such as ataxia-telangiectasia-like disorder,Nijmegen breakage syndrome,and Nijmegen breakage syndrome-like disorder that are caused by dysfunctions in the MRN complex.Furthermore,we summarize the mouse models established to study the clinical phenotypes of the above diseases.

- Abstract
Background: Count time series (e.g., daily deaths) are a very common type of data in environmental health research. The series is generally autocorrelated, while the widely used generalized linear model is based on the assumption of independent outcomes. None of the existing methods for modelling parameter-driven count time series can obtain consistent and reliable standard error of parameter estimates, causing potential inflation of type I error rate., Methods: We proposed a new maximum significant ρ correction (MSRC) method that utilizes information of significant autocorrelation coefficient ρ estimate within 5 orders by moment estimation. A Monte Carlo simulation was conducted to evaluate and compare the finite sample performance of the MSRC and classical unbiased correction (UB-corrected) method. We demonstrated a real-data analysis for assessing the effect of drunk driving regulations on the incidence of road traffic injuries (RTIs) using MSRC in Shenzhen, China. Moreover, there is no previous paper assessing the time-varying intervention effect and considering autocorrelation based on daily data of RTIs., Results: Both methods had a small bias in the regression coefficients. The autocorrelation coefficient estimated by UB-corrected is slightly underestimated at high autocorrelation (≥ 0.6), leading to the inflation of the type I error rate. The new method well controlled the type I error rate when the sample size reached 340. Moreover, the power of MSRC increased with increasing sample size and effect size and decreasing nuisance parameters, and it approached UB-corrected when ρ was small (≤ 0.4), but became more reliable as autocorrelation increased further. The daily data of RTIs exhibited significant autocorrelation after controlling for potential confounding, and therefore the MSRC was preferable to the UB-corrected. The intervention contributed to a decrease in the incidence of RTIs by 8.34% (95% CI, -5.69-20.51%), 45.07% (95% CI, 25.86-59.30%) and 42.94% (95% CI, 9.56-64.00%) at 1, 3 and 5 years after the implementation of the intervention, respectively., Conclusions: The proposed MSRC method provides a reliable and consistent approach for modelling parameter-driven time series with autocorrelated count data. It offers improved estimation compared to existing methods. The strict drunk driving regulations can reduce the risk of RTIs., (© 2024. The Author(s).)

- Abstract
Background: Venous thromboembolism significantly contributes to patient deterioration and mortality. Management of its etiology and anticoagulation treatment is intricate, necessitating a comprehensive consideration of various factors, including the bleeding risk, dosage, specific anticoagulant medications, and duration of therapy. Herein, a case of lower extremity thrombosis with multiple primary malignant tumors and high risk of bleeding was reviewed to summarize the shortcomings of treatment and prudent anticoagulation experience., Case Summary: An 83-year-old female patient was admitted to the hospital due to a 2-wk history of left lower extremity edema that had worsened over 2 d. Considering her medical history and relevant post-admission investigations, it was determined that the development of left lower extremity venous thrombosis and pulmonary embolism in this case could be attributed to a combination of factors, including multiple primary malignant tumors, iliac venous compression syndrome, previous novel coronavirus infection, and inadequate treatment for prior thrombotic events. However, the selection of appropriate anticoagulant medications, determination of optimal drug dosages, and establishment of an appropriate duration of anticoagulation therapy were important because of concurrent thrombocytopenia, decreased quantitative fibrinogen levels, and renal insufficiency., Conclusion: Anticoagulant prophylaxis should be promptly initiated in cases of high-risk thrombosis. Individualized anticoagulation therapy is required for complex thrombosis., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

- Abstract
Purpose: Plastic bronchitis (PB), a rare complication of respiratory infection characterized by the formation of casts in the tracheobronchial tree, can lead to airway obstruction and severe condition. Adenovirus is one of the common pathogens of PB caused by infection. This study aimed to evaluate the clinical features and risk factors for PB in children with severe adenovirus pneumonia., Methods: A retrospective study of children with severe adenovirus pneumonia with bronchoscopy results at Guangzhou Women and Children's Hospital between January 2018 and January 2020 was performed. Based on bronchoscopy, we divided children with severe adenovirus pneumonia into two groups: PB and non-PB. Binary logistic regression analysis was used to identify independent risk factors for PB in patients with severe adenovirus pneumonia after univariate analysis., Results: Our study examined 156 patients with severe adenovirus pneumonia with bronchoscopy results in hospital. Among them, 18 developed PB and 138 did not. On multivariate analysis, the independent risk factors of PB in children with severe adenovirus pneumonia were history of allergies (OR 10.147, 95% CI 1.727-59.612; P =0.010), diminished breath sounds (OR 12.856, 95% CI 3.259-50.713; P =0.001), and increased proportion of neutrophils (>70%; OR 8.074, 95% CI 1.991-32.735; P =0.003)., Conclusion: Children with severe adenovirus pneumonia with a history of allergies, diminished breath sounds, and increased the proportion of neutrophils >70% may show higher risk of PB., Competing Interests: The authors report no conflicts of interest in this work., (© 2024 Xu et al.)

- Abstract
Enhanced external counterpulsation (EECP) is a treatment and rehabilitation approach for ischemic diseases, including coronary artery disease. Its therapeutic benefits are primarily attributed to the improved blood circulation achieved through sequential mechanical compression of the lower extremities. However, despite the crucial role that hemodynamic effects in the lower extremity arteries play in determining the effectiveness of EECP treatment, most studies have focused on the diastole phase and ignored the systolic phase. In the present study, a novel siphon model (SM) was developed to investigate the interdependence of several hemodynamic parameters, including pulse wave velocity, femoral flow rate, the operation pressure of cuffs, and the mean blood flow changes in the femoral artery throughout EECP therapy. To verify the accuracy of the SM, we coupled the predicted afterload in the lower extremity arteries during deflation using SM with the 0D-1D patient-specific model. Finally, the simulation results were compared with clinical measurements obtained during EECP therapy to verify the applicability and accuracy of the SM, as well as the coupling method. The precision and reliability of the previously developed personalized approach were further affirmed in this study. The average waveform similarity coefficient between the simulation results and the clinical measurements during the rest state exceeded 90%. This work has the potential to enhance our understanding of the hemodynamic mechanisms involved in EECP treatment and provide valuable insights for clinical decision-making., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Because of their various reactivities, propargyl acetates are refined chemical intermediates that are extensively applied in pharmaceutical synthesis. Currently, reactions between propargyl acetates and chlorosilanes may be the most effective method for synthesizing silylallenes. Nevertheless, owing to the adaptability and selectivity of substrates, transition metal catalysis is difficult to achieve. Herein, nickel-catalyzed reductive cross-coupling reactions between propargyl acetates and substituted vinyl chlorosilanes for the synthesis of tetrasubstituted silylallenes are described. Therein, metallic zinc is a crucial reductant that effectively enables two electrophilic reagents to selectively construct C(sp
2 )-Si bonds. Additionally, a Ni-catalyzed reductive mechanism involving a radical process is proposed on the basis of deuteration-labeled experiments.- Published

- Abstract
Background: The high prevalence of hepatitis A delivered a blow to public health decades ago. The World Health Organization (WHO) set a goal to eliminate viral hepatitis including hepatitis A by 2030. In 2008, hepatitis A vaccines were integrated into the Expanded Program on Immunization (EPI) in China to alleviate the burden of hepatitis A, although the effectiveness of the EPI has not been well investigated., Objective: We aimed to evaluate the intervention effect at both provincial and national levels on the incidence of hepatitis A in the Chinese mainland from 2005 to 2019., Methods: Based on the monthly reported number of hepatitis A cases from 2005 to 2019 in each provincial-level administrative division, we adopted generalized additive models with an interrupted time-series design to estimate province-specific effects of the EPI on the incidence of hepatitis A among the target population (children aged 2-9 years) from 2005 to 2019. We then pooled province-specific effect estimates using random-effects meta-analyses. We also assessed the effect among the nontarget population and the whole population., Results: A total of 98,275 hepatitis A cases among children aged 2-9 years were reported in the Chinese mainland from 2005 to 2019, with an average annual incidence of 5.33 cases per 100,000 persons. Nationally, the EPI decreased the hepatitis A incidence by 80.77% (excess risk [ER] -80.77%, 95% CI -85.86% to -72.92%) during the study period, guarding an annual average of 28.52 (95% empirical CI [eCI] 27.37-29.00) cases per 100,000 persons among the target children against hepatitis A. Western China saw a more significant effect of the EPI on the decrease in the incidence of hepatitis A among the target children. A greater number of target children were protected from onset in Northwest and Southwest China, with an excess incidence rate of -129.72 (95% eCI -135.67 to -117.86) and -66.61 (95% eCI -67.63 to -64.22) cases per 100,000 persons on average, respectively. Intervention effects among nontarget (ER -32.88%, 95% CI -39.76% to -25.21%) and whole populations (ER -31.97%, 95% CI -39.61% to -23.37%) were relatively small., Conclusions: The EPI has presented a lasting positive effect on the containment of hepatitis A in the target population in China. The EPI's effect on the target children also provided a degree of indirect protection for unvaccinated individuals. The continuous surveillance of hepatitis A and the maintenance of mass vaccination should shore up the accomplishment in the decline of hepatitis A incidence to ultimately achieve the goal set by the WHO., (©Bo-Wen Ming, Li Li, Hao-Neng Huang, Jia-Jun Ma, Chen Shi, Xiao-Han Xu, Zhou Yang, Chun-Quan Ou.

- Abstract
Background: Giant congenital biliary dilation (CBD) is a rare condition observed in clinical practice. Infants born with this condition often experience a poor overall health status, and the disease progresses rapidly, leading to severe biliary obstruction, infections, pressure exerted by the enlarged CBD on abdominal organs, disturbances in the internal environment, and multiple organ dysfunction. The treatment of giant CBD using laparoscopy is challenging due to the high degree of variation in the shape of the bile duct and other organs, making it difficult to separate the bile duct wall from adjacent tissues or to control bleeding., Case Summary: Herein, we present the details of an 11-d-old male newborn who was diagnosed with giant CBD. The patient was admitted to the neonatal surgery department of our hospital due to a history of common bile duct cyst that was detected more than 3 mo ago, and also because the patient had been experiencing yellowish skin for the past 9 d. The abnormal echo in the fetal abdomen was first noticed by the patient's mother during a routine ultrasound examination at a local hospital, when the patient was at 24 wk + 6 d of pregnancy. This finding raised concerns about the possibility of congenital biliary dilatation (22 mm × 21 mm). Subsequent ultrasound examinations at different hospitals consistently confirmed the presence of a congenital biliary dilatation. No specific treatment was administered for biliary dilatation during this period. A computed tomography scan conducted during the hospitalization revealed a large cystic mass in the right upper quadrant and pelvis, measuring approximately 9.2 cm × 7.4 cm × 11.3 cm. Based on the scan, it was classified as a type I biliary dilatation., Conclusion: The analysis reveals that prenatal imaging techniques, such as ultrasound and magnetic resonance imaging, play a crucial role in the early diagnosis, fetal prognosis, and treatment plan for giant CBD. Laparoscopic surgery for giant CBD presents certain challenges, including difficulties in separating the cyst wall, anastomosis, and hemostasis, as well as severe biliary system infection and ulceration. Consequently, there is a high likelihood of converting to laparotomy. The choice between surgical methods like hepaticojejunostomy (HJ) or hepaticoduodenostomy has not been standardized yet. However, we have achieved favorable outcomes using HJ. Preoperative management of inflammation, biliary drainage, liver function protection, and supportive treatment are particularly vital in improving children's prognosis. After discharge, it is essential to conduct timely reexamination and close follow-up to identify potential complications., Competing Interests: Conflict-of-interest statement: All the authors report having no relevant conflicts of interest for this article., (©The Author(s) 2024.
