The validity of the cut-off values was assessed using receiver operating characteristic (ROC) curves, with cycloplegic retinoscopy serving as a reference. These results were compared to the age-based 2021 AAPOS diagnostic thresholds. Additionally, this study validated previously reported referral criteria within its population.Results: The study involved 1103 children (347 below four years; 756 aged four years and above). We established optimal cut-off points for hyperopia, myopia, astigmatism, and anisometropia: +2.13D, − 2.88D, − 2.88D, and 0.88D for children under four years; +1.88D, − 1.88D, − 2.13D, and 0.88D for those four years and older, forming the “Nanjing Referral Criteria”. The Youden index for several existing referral criteria ranged from 0.08 to 0.53 in detecting ARFs & VSRE and from 0.08 to 0.48 for ARFs, VSRE, and amblyopia.Conclusion: The study proposes the “Nanjing Referral Criteria” and its modified version with enhanced specificity for the Spot Vision Screener to optimize vision screening in children. Vision screening programs can utilize this validated data to select referral criteria best suited to their local context.Keywords: AAPOS guidelines, vision screening, referral criteria, the spot vision screener

Patients were allocated into HQC and non-HQC groups. Baseline data between the two groups were matched with propensity score matching (PSM). Influencing factors for the risk of re-admission in AS patients were analyzed with the Cox proportional hazards model. The effect of HQC intervention duration on the risk of re-admission was assessed with Kaplan-Meier survival curves. The random walk model and association rule analysis were utilized to determine the correlation between HQC and improvements in immunoinflammatory markers.Results: The re-admission rate was significantly lower in the HQC group than in the non-HQC group (P < 0.01). The risk of re-admission was significantly lower in patients aged > 40 years (P < 0.01) than in patients aged < 40 years and also markedly lower in HQC users than in non-HQC users (P < 0.01), suggesting that age and the use of HQC were key factors influencing the risk of re-admission. Longer HQC intervention duration was associated with better improvements in ESR, CRP, and C4, and HQC was closely correlated with improvements in ESR, CRP, IgA, and C4.Conclusion: HQC treatment can reduce the risk of re-admission in AS patients, which may be associated with improvements in ESR, CRP, IgA, and C4. The risk decreases with prolonged HQC treatment.Keywords: Huangqin Qingre Chubi Capsule, ankylosing spondylitis, re-admission, cohort study, telephone follow-up

Building upon previous research on the immunological and inflammatory aspects of JDM, this study aims to investigate the role of pyroptosis in the pathogenesis of JDM using a comprehensive bioinformatics approach.Methods: Two microarray datasets (GSE3307 and GSE11971) were obtained from the Gene Expression Omnibus database, and a list of 62 pyroptosis-related genes was compiled. Differential gene expression analysis and machine learning analysis were performed to identity the hub pyroptosis-related differentially expressed genes (PR-DEGs). Functional enrichment analysis, immune cell infiltration analysis, gene set variation analysis (GSVA), and gene set enrichment analysis (GSEA) were performed to elucidate the potential roles of PR-DEGs in JDM pathogenesis.Results: A total of 2526 common DEGs were identified, among which 12 PR-DEGs were identified, with CASP1, IRF1, NOD2, and PYCARD identified as hub PR-DEGs. These genes were involved in cytokine production, inflammasome activity, necroptosis, NOD-like receptor signaling, and TNF signaling. Immune infiltration analysis showed increased pro-inflammatory immune cell infiltration in JDM patients, with PR-DEGs positively correlated with various immune cell types. GSVA and GSEA analyses demonstrated the involvement of PR-DEGs in multiple inflammation and immunity-related pathways, with the NOD-like receptor signaling pathway playing a central role.Conclusion: This study highlights the crucial role of pyroptosis in the pathogenesis of JDM, with the identified PR-DEGs potentially contributing to disease development and progression by regulating key inflammatory and immune-related pathways.Keywords: pyroptosis, JDM, immune infiltration analysis, machine learning, diagnostic

Studies were categorized into high (HDG), moderate (MDG), and low (LDG) dosage groups based on acupuncture characteristics: the number of acupoints, total sessions, frequency per week, and the need for “Deqi”.Results: Of the 807 citations screened, 16 studies (1240 patients) were included: 3 studies in LDG, 10 in MDG, and 3 in HDG. Acupuncture significantly reduced angina attacks compared to placebo (SMD, − 0.51; 95% CI [− 0.77, − 0.25], P = 0.0001, I2=62%), and standard care (SMD, − 1.25, 95% CI [− 1.89, − 0.61], P = 0.00001, I2=92%) without increasing adverse events. MDG showed a notable difference in reducing angina attacks (SMD, − 0.60, 95% CI [− 0.91, − 0.29], P = 0.001, I2=60%) while LDG and HDG did not. There is no difference in adverse events between groups. The evidence quality ranged from very low to moderate, and the results should be cautiously applied.Conclusion: Acupuncture therapy effectively and safely alleviates CSA symptoms. Moderate dosage demonstrated the potential for better effects in reducing symptoms, suggesting optimal dosage considerations for future treatments.Prospero Registration Number: CRD42022321547.Keywords: acupuncture, chronic stable angina, dose-related, effectiveness, meta-analysis

Pittsburgh Sleep Quality Index (PSQI) score (odds ratio (OR) = 13.476, 95% confidence interval (CI) = 1.514– 119.923, P = 0.020), absolute GLS (OR = 0.328, 95% CI = 0.210– 0.510, P < 0.001), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) (OR = 1.050, 95% CI = 1.025– 1.076, P < 0.001) were identified as independent risk factors for inducing CCM.Conclusion: In patients with CCM, a decrease in sleep quality often occurs. When cirrhotic patients also have poor sleep quality, along with a decrease in absolute Global Left Ventricular Strain (GLS) levels and an increase in NT-proBNP levels, these factors may pose a higher risk for CCM development. However, further validation of these research findings is required in larger sample sizes.Keywords: cardiomyopathy, liver cirrhosis, sleep quality, cirrhotic cardiomyopathy

Traditional Tibetan medicine has a rich history of treating HUA. This study aimed to identify novel anti-hyperuricemic herb derived from traditional Tibetan medicine.Methods: Traditional Tibetan medicine prescriptions for HUA were analyzed using data mining techniques, identifying T. chebula as a high-frequency herb. Its phytochemical composition was characterized by UPLC-QE-Orbitrap-MS. Hyperuricemic rat models were treated with T. chebula to assess its effects on serum uric acid (UA) levels, renal inflammation, intestinal barrier integrity, and gut microbiota composition. Molecular and histological analyses evaluated its impact on key biomarkers.Results: Through data mining, we identified T. chebula as a promising candidate for HUA treatment. T. chebula demonstrated dose-dependent inhibition of xanthine oxidase (XOD) in vitro and significantly reduced serum UA levels and XOD activity in vivo. It restored gut barrier function by upregulating tight junction proteins (ZO-1, Occludin, Claudin-1) and reduced pro-inflammatory cytokines (IL-6, TNF-α). T. chebula improved renal function, reducing serum creatinine (Cre) and blood urea nitrogen (BUN) levels. Gut microbiota analysis revealed a favorable shift in microbial composition, with reductions in harmful bacteria (eg, Clostridium spp.) and increases in beneficial bacteria (eg, Roseburia). These effects aligned with the modulation of the gut-kidney axis.Conclusion: This study highlights the multi-target therapeutic potential of T. chebula in HUA management. By regulating the gut-kidney axis, T. chebula alleviates systemic inflammation, enhances intestinal and renal health, and addresses critical aspects of HUA pathology. These findings underscore the value of integrating traditional medicine with modern scientific methodologies to develop innovative treatments.

Targeting the UPS is becoming a promising approach in cancer therapy. However, the role of UPS modulation in thyroid carcinoma (THCA) remains to be fully elucidated.Methods: Initially, we utilized data from The Cancer Genome Atlas (TCGA) database to employ weighted gene co-expression network analysis (WGCNA) with LASSO regression to develop a prognostic model for core UPS genes implicated in THCA. Subsequently, we stratified the THCA training set into two distinct subtypes based on ubiquitin-proteasome system prognostic model score (UPS-PMS) characteristics. Key genes within the model were then subjected to functional analysis, immunotherapy evaluation, and drug sensitivity studies.Results: We delineated a prognostic model of the UPS comprising six genes, which we subsequently demonstrated was capable of forecasting patient prognosis. Moreover, our findings indicated a substantial correlation between UPS-PMS and immune microenvironmental factors, notably a negative correlation with myeloid immune cells and a potential influence on the Th1 to Th2 cells ratio. Especially, we observed a significant association between high UPS-PMS and an immunosuppressive microenvironment. Then, we elucidated the biological distinctions among various THCA sample subtypes, highlighting that the cluster_1 subtype is associated with an unfavorable prognosis. Of note, KCNA1 was identified as a pivotal prognostic gene within the UPS-PMS framework. We constructed a three-tiered regulatory network centered on KCNA1-related competing endogenous RNA (ceRNA). Furthermore, our results suggested that KCNA1 has potential as a target for immunotherapeutic strategies. Concurrently, drug sensitivity analyses demonstrated that high KCNA1 expression promoted gemcitabine resistance in patients, while KCNA1 knockdown increased sensitivity to gemcitabine.Conclusion: In conclusion, we developed a novel UPS-based prognostic model for THCA, identified key gene KCNA1, and assessed immunotherapy and drug sensitivity, revealing new therapeutic targets.Keywords: ubiquitin-proteasome system, thyroid carcinoma, prognostic model, immune microenvironment, drug sensitivity

Traditional imaging methods, while standard, have limitations in detecting subtle fractures and distinguishing them from complex bone structures. The advent of 3D Convolutional Neural Networks (3D-CNNs) offers a promising avenue for enhancing the accuracy and reliability of ankle fracture diagnoses.Methods: In this study, we acquired 1453 high-resolution CT scans and processed them through three distinct 3D-CNN models: 3D-Mobilenet, 3D-Resnet101, and 3D-EfficientNetB7. Our approach involved meticulous preprocessing of images, including normalization and resampling, followed by a systematic comparative evaluation of the models based on accuracy, Area Under the Curve (AUC), and recall metrics. Additionally, the integration of Gradient-weighted Class Activation Mapping (Grad-CAM) provided visual interpretability of the models’ predictive focus points.Results: The 3D-EfficientNetB7 model outperformed the other models, achieving an accuracy of 0.91 and an AUC of 0.94 after 20 training epochs. It demonstrated particularly effective in the accurate detection and localization of subtle and complex fractures. Grad-CAM visualizations confirmed the model’s focus on clinically relevant areas, aligning with expert assessments and enhancing trust in automated diagnostics. Spatial localization techniques were pivotal in improving interpretability, offering clear visual guidance for pinpointing fracture sites.Conclusion: Our findings highlight the effectiveness of the 3D-EfficientNetB7 model in diagnosing ankle fractures, supported by robust performance metrics and enhanced visualization tools.Keywords: 3d convolutional neural networks, ankle fractures, diagnostic accuracy, Grad-CAM, image processing, machine learning, medical imaging, orthopedic diagnostics

Hierarchical architecture growth mimicking biomineralization has been studied using various organic molecules to template inorganic materials with controlled morphology. In our previous study, self-assembled Sr/CS/G(SrCO3-chitosan-gelatin) aggregates were fabricated using electrophoretic deposition (EPD). This study is a further step toward understanding the morphogenesis of Sr/CS/G aggregates and its biomineralization.Methods: Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) were used to investigate the biomimetic morphogenesis of Sr/CS/G composite under various EPD parameters, such as polymer concentration, time, and voltage. The Sr/CS/G aggregates were immersed in H2O, phosphate-buffered saline (PBS), and simulated body fluid (SBF) to study the bioactive apatite formation ability. In addition, biocompatibility of the composites were evaluated by Fluorescence staining, SEM in vitro. The osteogenic ability of the coatings induced by PBS were tested in vivo.Results: The CS/G weight ratio, EPD time, and voltage were found to influence the morphogenesis of Sr/CS/G aggregates. SEM and TEM results showed that the Sr/CS/G aggregates exhibited fractal growth characteristics and morphological self-similarity. XRD results confirmed the formation of SrCO3 crystals within the framework of chitosan and gelatin organic templates. Chitosan played a vital role in branching growth of the crystals, whereas gelatin guided the formation of composite spheres. The microstructural and compositional results reveal that the Sr/CS/G-induced apatite coating yielded a large quantity of apatite. These apatite coatings promote the cytocompatibility and osteogenesis of rat bone marrow mesenchymal stem cells (rBMSCs) in vitro. The coatings induced by PBS enhanced proliferation and mineralization in vitro, and enhanced angiogenesis and osteogenesis in vivo.Conclusion: Sr/CS/G composites prepared via EPD are promising organic-inorganic templates for biomineralization. These findings provide important insights into understanding the mineralization process and optimizing the design of advanced biological materials.Keywords: biomineralization, EPD parameter, Sr/CS/G aggregates, morphogenesis, hydroxyapatite

Changes in the visual analog scale (VAS), Oswestry Disability Index (ODI), and quality of life assessment scale(QOL) were evaluated regularly. Postoperative complications and target lesion tumor treatment responses were also observed.Results: The VAS and ODI in both the MWA+PO group and the PO group significantly decreased at 1 week, 1 month, and 3 months postoperatively, The VAS and ODI in the MWA+PO group were lower than those in the PO group postoperatively. The QOL in both the MWA+PO group and the PO group significantly increased at 1 week, 1 month, and 3 months postoperatively, with the QOL in the MWA+PO group being higher than that in the PO group postoperatively. According to the mRECIST criteria (target lesion tumor treatment response), the ORR in the MWA+PO group and PO group was 52.8% and 9.5%, respectively, while the DCR was 94.4% and 57.1%, respectively (P < 0.001 and< 0.001). Different degrees of bone cement extravasation were observed in both the PO group (38.1%) and MWA+PO group(19.4%)(χ²=2.38, P=0.12), but none of the patients developed clinical symptoms related to bone cement extravasation. The average cost of surgery was ¥ 10,480.43 higher in the MWA+PO group than in the PO group.Conclusion: The MWA+PO treatment is more effective in relieving patients’ local pain, improving local dysfunction, and enhancing quality of life, and can effectively improve target lesion tumor ORR and DCR, but it is also more costly.Keywords: microwave ablation, percutaneous osteoplasty, bone metastases

Furthermore, 909 (69.66%) of these institutions offered annual free physical examination services to individuals aged 65 and above. Notably, a total of 362 medical institutions, encompassing both comprehensive hospitals and grassroots hospitals, were recognized as elderly-friendly institutions, accounting for 31.4% of the surveyed sample.The highest demand for talents in medical institutions at all levels included specialized physicians/general practitioners (74.6%), traditional Chinese medicine practitioners (63.1%), rehabilitation therapists (56.1%), and specialized nurses for the elderly (41.7%). A total of 1038 medical institutions conducted popular science activities on elderly health, accounting for 79.5% of the total, focusing mainly on disease prevention (89.21%), nutritional diets (84.68%), rational medication use (79.77%), physical exercise (68.21%), and mental health (60.79%). Only 88 medical institutions provided hospice care services, accounting for 6.7% of the total.Conclusion: Guangxi medical institutions’ elderly services are inadequate. Geriatrics and rehab departments are scarce, talent is lacking, and hospice care is underdeveloped. As aging accelerates, the country and society must support elderly care. Governments should introduce talent incentives, and medical institutions should enhance services, foster a positive work environment, and advance Guangxi’s elderly health agenda.Keywords: medical institutions, elderly health services, elderly care, hospice care, current status

This study used single-cell transcriptomics technology to investigate the changes in various cell subtypes during MIRI and the regulatory network of ferroptosis-related genes and immune infiltration.Methods: Datasets GSE146285, GSE83472, GSE61592, and GSE160516 were obtained from Gene Expression Omnibus. Each cell subtype in the tissue samples was documented. The Seurat package was used for data preprocessing, standardization, and clustering. Cellphonedb was used to investigate the ligand-receptor interactions between cells. The hdWGCNA analysis was used to create a gene co-expression network. GSVA and GSEA were combined to perform functional enrichment and pathway analysis on the gene set. Furthermore, characteristic genes of the disease were identified using Lasso regression and SVM algorithms. Immune cell infiltration analysis was also performed. MIRI rat models were created, and samples were taken for RT-qPCR and Western blot validation.Results: The proportion of MIRI samples in the C2, C6, and C11 subtypes was significantly higher than that of control samples. Three genes associated with ferroptosis (CD44, Cfl1, and Zfp36) were identified as MIRI core genes. The expression of these core genes was significantly correlated with mast cells and monocyte immune infiltrating cells. The experimental validation confirmed the upregulation of Cd44 and Zfp36 expression levels in MIRI, consistent with current study trends.Conclusion: This study used single-cell transcriptomics technology to investigate the molecular mechanisms underpinning MIRI.

All participants were followed up for 9 years, with a median of 54 months (2451 person-years). The subjects were categorized into two groups: the ATDs group (n = 414) and the RAI group (n = 126). According to the free triiodothyronine (FT3) tertiles, the patients receiving RAI were further grouped as follows: low-level (≤ 4.70 pmol/L, n = 42), moderate-level (4.70– 12.98 pmol/L, n = 42), and high-level (≥ 12.98 pmol/L, n = 42). The efficacy of ATDs and RAI therapies in reducing the risk of MACEs and all-cause mortality was assessed.Results: Of the 540 participants, 163 experienced MACEs (30.19%), 25 (15.34%) of whom died. Multivariate Cox regression analyses revealed that RAI was associated with a 38.5% lower risk of MACEs (P = 0.016) and a 77.1% lower risk of all-cause mortality (P = 0.046). Stratified analyses indicated that RAI had a protective effect on MACEs in patients aged ≥ 60 years (P = 0.001, P for interaction = 0.031) and patients with a duration of diabetes mellitus ≥ 6 years (P = 0.013, P for interaction = 0.002). Kaplan‒Meier analysis revealed a lower cumulative incidence of MACEs and all-cause mortality in the RAI group (log-rank, all P < 0.05). Moreover, the ROC curve suggested an optimal FT3 cut-off value of 5.4 pmol/mL for MACE (P < 0.001).Conclusion: Our findings suggested that RAI therapy effectively reduced the risk of MACEs and all-cause mortality in elderly patients with hyperthyroidism combined with T2DM.Keywords: hyperthyroidism, type 2 diabetes mellitus, radioactive iodine-131, major adverse cardiovascular events, all-cause mortality

But the independent and combined effects of them on mental health among patients with chronic obstructive pulmonary disease (COPD) are uncertain.Methods: The independent and combined effects of education and living environment on mental health were assessed by binary logistic regression in 1064 COPD patients. Additive interaction was assessed with the relative excess risk ratio (RERI), attribution percentage (AP), and synergy index (SI).Results: Our results shown that low education level and urban living environment were independently associated with higher risks for anxiety (odds ratio [OR]: 1.56, 95% confidence interval [CI] 1.06– 2.29 and OR:2.15, 95% CI 1.51– 2.05) or depression (OR:1.62, 95% CI 1.17– 2.27 and OR: 2.01, 95% CI 1.46– 2.75) among COPD patients. The combination effect of them was also associated with higher risks for anxiety (OR: 7.90, 95% CI 3.83– 16.29, P < 0.001) or depression (OR: 11.79, 95% CI 5.77– 24.10, P < 0.001) among these patients. Furthermore, we observed strong synergistic additive interactions between them for anxiety (SI: 11.57, 95% CI 1.41– 95.27; RERI: 6.31, 95% CI 1.60– 11.01; AP: 0.8, 95% CI 0.66– 0.94) and depression (SI: 31.31, 95% CI 1.59– 617.04; RERI: 10.44, 95% CI 2.66– 18.23; AP: 0.89, 95% CI 0.8– 0.97).Conclusion: Low education levels and living in urban areas had an independent and synergistic effects on mental health among COPD patients.Keywords: anxiety, China, COPD, depression, education, living environment

However, the association of systemic inflammation levels with total and cardiovascular death among patients with HFpEF remains unknown. We aimed to investigate the prognostic impact of systemic inflammation on all-cause and cardiovascular death among patients with HFpEF.Patients and Methods: Patients with HFpEF were included in this study. Systemic inflammation response index (SIRI) is defined as the multiplication of neutrophil and monocyte divided by lymphocyte count, and patients were divided into four groups based on SIRI quartiles. Cox regression models and competing risk models were used to examine the relationships between SIRI and total and cardiovascular‑specific mortality, respectively.Results: 9,986 patients with HFpEF were included in five tertiary hospitals. During a median follow-up period of 4.4 years, a total of 2004 patients died, of which 965 were cardiovascular deaths. After fully adjusting for confounders, elevated SIRI level was significantly related to the increased risk of all-cause death (Q2, Q3, Q4: adjusted hazard ratio (aHR) [95 confidence interval (CI)%] =1.17[1.01– 1.35], 1.31[1.13– 1.52], 1.51[1.30– 1.76], respectively; P for trend < 0.001). The elevated quartile of SIRI showed higher risks of cardiovascular death, but there was no statistically significant increased risk of cardiovascular death across the lower SIRI quartile (model 3: Q2, Q3, Q4: aHR [95CI%] =1.22[0.99– 1.51], 1.50[1.20– 1.86], 1.73[1.37– 2.18], respectively; P for trend < 0.001).Conclusion: Elevated systemic inflammation level on admission was correlated with an increased risk of all-cause and cardiovascular death among patients with HFpEF. The SIRI may serve as a promising marker of risk stratification for patients with HFpEF.Keywords: heart failure with preserved ejection fraction, systemic inflammatory response index, all-cause death, cardiovascular death

The inflammatory response within the tumor microenvironment plays an important role in GC progression.Methods: We downloaded GC-related datasets and inflammation-related genes from GEO, TCGA and MSigDB databases, performed differential analysis, protein-protein interaction analysis, immunoinfiltration analysis and Lasso analysis to screen inflammation-related hub genes affecting GC progression, and carried out qRT-PCR for validation. In order to explore the role of ADH1A, we constructed overexpressed plasmids, treated GC cells with cGMP/PKG pathway agonist 8-Br-cGMP, and tested cell functions with CCK8, EdU, Transwell, scratch assay and other experiments. On this basis, GC cells were co-cultured with monocyte THP-1 to explore the effect of ADH1A on the polarization of macrophages.Results: ADH1A was significantly decreased in GC cells, and its expression trend was consistent with the results of bioinformatics analysis. Therefore, we chose ADH1A for subsequent functional validation. Overexpression of ADH1A in GC cells revealed ADH1A’s role in inhibiting the activity, proliferation, migration and invasion of GC cells, promoting apoptosis and secretion of IL-6, IFN-γ, CCL5 and CSF2, and facilitating the transformation of macrophages to a pro-inflammatory M1 phenotype. ssGSEA results demonstrated the potential involvement of ADH1A in the cGMP/PKG signaling pathway, and significant changes in the expression of proteins related to the cGMP/PKG signaling pathway. The use of the cGMP/PKG signaling pathway agonist 8-Br-cGMP in ADH1A-overexpressing GC cells substantiated ADH1A’s capacity to inhibit the cGMP/PKG signaling pathway, thereby suppressing the malignant progression of GC and promoting the transformation of macrophages to a pro-inflammatory M1 phenotype.Conclusion: ADH1A is able to influence the malignant progression of GC and the transformation of macrophages to the pro-inflammatory M1 phenotype through the cGMP/PKG signaling pathway.Keywords: gastric cancer, inflammation, immune infiltration analysis, ADH1A, cGMP/PKG signaling pathway

Don (P. capitatum), a traditional herb used in Miao medicine, is renowned for its heart-clearing properties. Davidiin, the primary bioactive component (approximately 1%), has been used to treat various conditions, including diabetes. Given its wide range of effects and the diverse biomolecular pathways involved in diabetes, there is a crucial need to study how davidiin interacts with these pathways to better understand its anti-diabetic properties.Materials and Methods: Diabetic rats were induced using a high-fat diet and streptozotocin (STZ) administered intraperitoneally at 35 mg/kg. Out of these, 24 rats with blood glucose levels ≥ 11.1 mmol/L and fasting blood glucose levels ≥ 7.0 mmol/L were selected for three experimental groups. These groups were then treated with either metformin (gavage, 140 mg/kg) or davidiin (gavage, 90 mg/kg) for four weeks. After the treatment period, we measured body weight, blood glucose levels, and conducted untargeted metabolic profiling using UPLC-QTOF-MS.Results: Davidiin has been shown to effectively treat diabetes by reducing blood glucose levels from 30.2 ± 2.6 mmol/L to 25.1 ± 2.4 mmol/L (P < 0.05). This effect appears stronger than that of metformin, which lowered glucose levels to 26.5 ± 2.6 mmol/L. The primary outcomes of serum metabolomics are significant changes in lipid and lipid-like molecular profiles. Firstly, davidiin may affect phosphatide metabolism by increasing levels of phosphatidylinositol and sphingosine-1-phosphate. Secondly, davidiin could influence cholesterol metabolism by reducing levels of glycocholic acid and glycochenodeoxycholic acid. Lastly, davidiin might impact steroid hormone metabolism by increasing hepoxilin B3 levels and decreasing prostaglandins.Conclusion: Our study demonstrates that davidiin modulates various lipid-related metabolic pathways to exert its anti-diabetic effects. These findings offer the first detailed metabolic profile of davidiin’s action mechanism, contributing valuable insights to the field of Traditional Chinese Medicine in the context of diabetes treatment.Keywords: diabetes mellitus, streptozotocin, metformin, davidiin, metabolomics

Nonetheless, its substantial cost places a significant burden on social health resources and patients. However, the cost-effectiveness (CE) of regorafenib compared to other third-line therapies is still undetermined.Objective: This study aims to assess the CE of regorafenib compared to other third-line therapies for the treatment of mCRC.Methods: We conducted a comprehensive literature search in PubMed, Medline, Scopus, Embase, Cochrane Library, as well as nine other databases to identify relevant studies published up to October 2023, focusing on patients with mCRC and examining the cost-effectiveness of regorafenib. Following the screening and extraction of pertinent data, the study quality was assessed using the Quality of Health Economic Studies (QHES) checklist.Results: The literature search yielded 751 records, and after applying the inclusion criteria, 13 studies from 7 different countries were included. Of these, 7 studies evaluated the cost-effectiveness of regorafenib compared to trifluridine/tipiracil (TAS-102), 3 studies compared regorafenib with best supportive care (BSC), and 3 studies compared regorafenib with fruquintinib, serplulimab, and regorafenib dose optimization (ReDo).The quality of the included studies was high with an average QHES scores of 85.62. Regorafenib standard dose proves to be less cost-effective than alternative third-line therapies. Implementing a dose optimization strategy could potentially rectify this disparity and enhance the cost-effectiveness of regorafenib.Conclusion: The use of the standard dose of regorafenib is generally regarded as not cost-effective when compared to other third-line therapies for patients with mCRC. However, implementing a dose-escalation strategy may enhance regorafenib’s cost-effectiveness. Consequently, significant price reductions or optimizing the dose of regorafenib are required to achieve cost-effectiveness.Keywords: regorafenib, metastatic colorectal cancer, cost-effectiveness, incremental cost-effectiveness ratios

Complex immune microenvironment of the liver is linked to the development of HCC. PVALB is a calcium-binding protein which has been described as a cancer suppressor gene in thyroid cancer and glioma. Nevertheless, the role of PVALB in HCC is unknown.Materials and Methods: We obtained data from TCGA and GSE54236 datasets. MCP-counter, WGCNA and LASSO model were applied to identify PVALB. With UALCAN, MethSurv, and other websites, we probed the expression, methylation and survival of PVALB. LinkedOmics and GSEA were adopted for functional analysis, while TIMER, TISIDB, Kaplan-Meier plotter, TIDE databases were utilized to evaluate the relevance of PVALB to the tumor immune microenvironment and predict immunotherapy efficacy. TargetScan, DIANA, LncRNASNP2 databases and relevant experiments were employed to construct ceRNA network. Finally, molecular docking and drug sensitivity of PVALB were characterized by GeneMANIA, CTD, and so on.Results: PVALB was recognized as a gene associated with HCC and NK cell. Its expression was down-regulated in HCC tissue, which lead to adverse prognosis. Besides, the hypomethylation of PVALB was related to its reduced expression. Notably, PVALB was tightly linked to immune, and its reduced expression attenuated the anticancer effect of NK cells via the Fas/FasL pathway, leading to a adverse outcome. The lnc-YY1AP1-3/hsa-miR-6735-5p/PVALB axis may regulate the PVALB expression. Finally, we found immunotherapy might be a viable treatment option.Conclusion: In a word, PVALB is a prognostic indicator, whose low expression facilitates HCC progression by impacting NK cell infiltration.Keywords: PVALB, hepatocellular carcinoma, immune, ceRNA, bioinformatics, prognostic factor

This study explores the integration of machine learning (ML) with radiomics to predict functional recovery in dyskinetic myocardial segments in CAD patients undergoing revascularization, aiming to overcome these limitations.Methods: This prospective study enrolled 55 chronic CAD patients, dividing into training (39 patients, 205 segments) and testing sets (16 patients, 68 segments). Dysfunctional myocardial segments were identified by initial wall motion scores (WMS) of ≥ 2 (hypokinesis or higher). Functional recovery was defined as a decrease of ≥ 1 grade in WMS during follow-up echocardiography. Radiomics features were extracted from dyssynergic segments in end-systolic phase MCE images across five cardiac cycles post- “flash” impulse and processed through a five-step feature selection. Four ML classifiers were trained and compared using these features and MCE parameters, to identify the optimal model for myocardial recovery prediction.Results: Functional improvement was noted in 139 out of 273 dyskinetic segments (50.9%) following revascularization. Receiver Operating Characteristic (ROC) analysis determined that myocardial blood flow (MBF) was the most precise clinical predictor of recovery, with an area under the curve (AUC) of 0.770. Approximately 1.34 million radiomics features were extracted, with nine features identified as key predictors of myocardial recovery. The random forest (RF) model, integrating MBF values and radiomics features, demonstrated superior predictive accuracy over other ML classifiers. Validation of the RF model on the testing dataset demonstrated its effectiveness, evidenced by an AUC of 0.821, along with consistent calibration and clinical utility.Conclusion: The integration of ML with radiomics from MCE effectively predicts myocardial recovery in CAD. The RF model, combining radiomics and MBF values, presents a non-invasive, precise approach, significantly enhancing CAD management.Keywords: coronary artery disease, myocardial contrast echocardiography, radiomics, machine learning, myocardial recovery prediction, random forest

Simultaneously, patients matched to the case group in terms of gender and age but excluded for HCC were enrolled at a 1:1 ratio and classified as the control group. Relevant parameters were collected from both groups for comparison.Results: Both AFP levels and ultrasound results demonstrated diagnostic value for patients with HCC (P < 0.05). Their combined use exhibited the highest diagnostic accuracy for the cancer, with an area under the curve of 0.896 (95% confidence interval [CI]: 0.876, 0.923), a sensitivity of 67.65% and a specificity of 91.22%. In terms of overall survival (OS), statistically significant differences in the OS rates were observed between the low-AFP (L-AFP) group and high-AFP (H-AFP) group as well as between the low-tumour-diameter (LTD) group and high-tumour-diameter (HTD) group (81.31% vs 52.22% and 85.11% vs 63.41%, respectively; P < 0.05). Regarding the progression-free survival (PFS), significant differences in the PFS rates were also noted between the L-AFP and H-AFP groups and between the LTD and HTD groups (81.31% vs 52.22% and 85.11% vs 63.41%, respectively; P < 0.05).Conclusion: Ultrasound and AFP display notable distinctions when used in the diagnosis of HCC. The sensitivity of ultrasound as a standalone diagnostic tool surpasses that of AFP alone. However, their combined use results in much higher specificity than the use of either test individually. In addition, both techniques hold predictive value for patients’ OS and PFS, enabling timely prognostic assessment.Keywords: alpha-fetoprotein, hepatocellular liver cancer, ultrasound, survival analysis, prognosis

Our study aims to construct an early prediction model for hospital mortality in patients with pneumonia-associated ARDS.Methods: In this single-center retrospective study, consecutive patients with pneumonia-associated ARDS admitted into intensive care units (ICUs) in West China Hospital of Sichuan University in China between January 2012 and December 2018 were enrolled. The least absolute shrinkage and selection operator (LASSO) regression and then multivariate logistic regression analysis were used to identify independent predictors which were used to develop a nomogram. We evaluated the performance of differentiation, calibration, and clinical utility of the nomogram.Results: The included patients were divided into the training cohort (442 patients) and the testing cohort (190 patients) with comparable baseline characteristics. The independent predictors for hospital mortality included age (OR: 1.04; 95% CI: 1.02, 1.05), chronic cardiovascular diseases (OR: 2.62; 95% CI: 1.54, 4.45), chronic respiratory diseases (OR: 1.87; 95% CI: 1.02, 3.43), lymphocytes (OR: 0.56; 95% CI: 0.39, 0.81), albumin (OR: 0.94; 95% CI: 0.90, 1.00), creatinine (OR: 1.00; 95% CI: 1.00, 1.01), D-dimer (OR: 1.06; 95% CI: 1.03, 1.09) and procalcitonin (OR: 1.14; 95% CI: 1.07, 1.22). A web-based dynamic nomogram (https://h1234.shinyapps.io/dynnomapp/) was constructed based on these factors. The concordance index (C index) of the nomogram was 0.798 (95% CI: 0.756, 0.840) in the training cohort and 0.808 (95% CI: 0.747, 0.870) in testing cohort. The precision–recall (PR) curves, calibration curves, decision curve analyses (DCA) and clinical impact curves showed that the nomogram has good predictive value and clinical utility.Conclusion: We developed and evaluated a convenient nomogram consisting of 8 clinical characteristics for predicting mortality in patients with pneumonia-associated ARDS.Keywords: pneumonia, acute respiratory distress syndrome, mortality, risk factors, nomogram

This metabolic reprogramming worsens inflammation and cascades into organ damage. Angiotensin-(1-7) [Ang-(1-7)], a small molecule, has demonstrated anti-inflammatory properties. This study investigates whether Ang-(1-7) mitigates inflammation in LPS-induced macrophages and septic mice by regulating the Warburg effect in immune metabolism.Methods: The study induced macrophages with LPS in vitro and measured inflammatory factors using ELISA and Western blot. Key enzymes in glycolysis, mitochondrial respiratory complexes, and citrate pathway key molecules were assessed using Western blot and qRT-PCR. Mitochondrial membrane potential (MMP), lactate, and ATP were measured using assay kits. In vivo, a mouse model of sepsis induced by LPS was used. Kidney tissues were examined for pathological and mitochondrial ultrastructural alterations. The levels of inflammatory factors in mouse serum, glycolysis and citrate pathway-related molecules in the kidney were assessed using qRT-PCR, Western blot, and immunofluorescence techniques. Additionally, MMP, lactate, and ATP in the kidney were measured using assay kits.Results: In vitro experiments demonstrated that Ang-(1-7) inhibited the levels of inflammatory factors in LPS-treated RAW264.7 cells. It also reduced the expression of key glycolytic enzymes HK2, PFKFB3, and PKM2, as well as lactate levels. Additionally, it decreased intracellular citrate accumulation, enhanced mitochondrial respiratory complexes I and III, and ATP levels. Ang-(1-7) alleviated MMP damage, modulated citrate pathway-related molecules, including SLC25A1, ACLY, and HIF-1α. In vivo experiments showed that Ang-(1-7) lowered glycolysis levels in septic mice, improved mitochondrial ultrastructure and function, mitigated inflammation and renal tissues damage in septic mice, and suppressed the expression of key molecules in the citrate pathway.Conclusion: In conclusion, Ang-(1-7) can regulate the Warburg effect through the citrate pathway, thereby alleviating inflammation in LPS-induced macrophages and septic mice.Keywords: Ang-(1-7), macrophage, sepsis, Warburg effect, glycolysis, citrate

Compared to conventional tissue regeneration methods, nano-bioactive materials have become the optimal materials with excellent physicochemical properties and biocompatibility. Dental-derived mesenchymal stem cells (DMSCs) are a particular type of mesenchymal stromal cells (MSCs) with great potential in tissue regeneration and differentiation. This paper presents a review of the application of various nano-bioactive materials for the induction of differentiation of DMSCs in oral and maxillofacial restorations in recent years, outlining the characteristics of DMSCs, detailing the biological regulatory effects of various nano-materials on stem cells and summarizing the material-induced differentiation of DMSCs into multiple types of tissue-induced regeneration strategies. Nanomaterials are different and complementary to each other. These studies are helpful for the development of new nanoscientific research technology and the clinical transformation of tissue reconstruction technology and provide a theoretical basis for the application of nanomaterial-modified dental implants. We extensively searched for papers related to tissue engineering bioactive constructs based on MSCs and nanomaterials in the databases of PubMed, Medline, and Google Scholar, using keywords such as “mesenchymal stem cells”, “nanotechnology”, “biomaterials”, “dentistry” and “tissue regeneration”. From 2013 to 2023, we selected approximately 150 articles that align with our philosophy.Keywords: nano-material, stem cell, tissue reconstruction, cell differentiation

Recently, emerging evidence has supported the therapeutic effect of magnesium administration in chronic pain. However, the role of magnesium supplementation in development of chronic pain after breast cancer surgery remains less known. The aim of this study was to evaluate therapeutic effect of magnesium supplementation on persistent pain after breast cancer procedure.Patients and Methods: This was a randomized, double-blind, placebo-controlled clinical trial. A total of 109 patients who underwent breast cancer procedure received magnesium-L-threonate (n = 48) or placebo (n = 61) for 12 weeks. Chronic pain incidence, short form of the McGill Pain Questionnaire (SF-MPQ), Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), and Telephone Interview for Cognitive Status (TICS) were evaluated at 3- and 6-month follow-up.Results: About 31% (15 out of 48) of patients reported chronic pain after magnesium supplementation, and 26% (16 out of 61) of the control group at 6-month follow-up respectively. Total scores of SF-MPQ were significantly increased in the control group 6 months after surgical intervention (mean difference, 1.475; 95% CI, − 2.730 to − 0.2211), but NOT in the magnesium treated group (mean difference, 1.250; 95% CI, − 2.775 to 0.2748). No significant differences were found between two cohorts on SF-MPQ, GAD-7, PHQ-9, PSQI, or TICS at each timepoint.Conclusion: Oral supplementation of magnesium-L-threonate did not effectively prevent the development of persistent pain in breast cancer survivors, nor provide sufficient pain relief over placebo. We did not observe improvement of pain, mood, sleep disorder, or cognitive function after 12-week magnesium supplementation. Future study may focus on magnesium combined with other effective anti-neuropathic pain treatment.Keywords: breast cancer surgery, chronic pain, magnesium-l-threonate, neuropathic pain, pain management

The value of hematological indicators in patients at high risk of Omicron infection remains unclear. We need rapid, inexpensive and widely available biomarkers to guide the early detection of people at risk of pneumonia and to provide early intervention. We aimed to assess the value of hematological indicators as risk factors for pneumonia in symptomatic COVID-19 patients infected with the SARS-CoV-2 Omicron variant.Patients and Methods: The study enrolled 144 symptomatic COVID-19 patients with Omicron infection. We collected available clinical details, including laboratory tests and CT examinations. Univariate and multivariate logistic analyses and receiver operating characteristic (ROC) curve analyses were used to assess the value of laboratory markers in predicting the development of pneumonia.Results: Among the 144 patients, 50 (34.7%) had pneumonia. The ROC analysis revealed that the areas under the ROC curve (AUC) for leukocytes, lymphocytes, neutrophils, and fibrinogen were 0.603 (95% confidence interval (CI): 0.501– 0.704, P=0.043), 0.615 (95% CI: 0.517– 0.712, P=0.024), 0.632 (95% CI: 0.534– 0.730, P=0.009) and 0.635 (95% CI: 0.539– 0.730, P=0.008), respectively. The AUC for neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), fibrinogen to lymphocyte ratio (FLR), and fibrinogen to D-dimer ratio (FDR) were 0.670 (95% CI: 0.580– 0.760, P=0.001), 0.632 (95% CI: 0.535– 0.728, P=0.009), 0.669 (95% CI: 0.575– 0.763, P=0.001) and 0.615 (95% CI: 0.510– 0.721, P=0.023), respectively. Univariate analysis showed that elevated levels of NLR (odds ratio (OR): 1.219, 95% CI: 1.046– 1.421, P=0.011), FLR (OR: 1.170, 95% CI: 1.014– 1.349, P=0.031) and FDR (OR: 1.131, 95% CI: 1.039– 1.231, P=0.005) were significantly correlated with the presence of pneumonia. Multivariate analysis indicated elevated NLR (OR: 1.248, 95% CI: 1.068– 1.459, P=0.005) and FDR (OR: 1.160, 95% CI: 1.054– 1.276, P=0.002) levels were associated with the existence of pneumonia. The AUC for the combination of NLR and FDR was 0.701 (95% CI: 0.606– 0.796, P< 0.001, sensitivity 56.0%, specificity 83.0%).Conclusion: NLR and FDR can predict the presence of pneumonia in symptomatic COVID-19 patients infected with the SARS-CoV-2 Omicron variant.Keywords: COVID-19, Omicron, pneumonia, neutrophil to lymphocyte ratio, fibrinogen, D-dimer

Through the integration of the cognitive-affective processing system and conservation of resources (COR) theory, the present study takes integrative complexity as a moderator, and explores the mechanism of LMX ambivalence on employees’ bootleg innovation.Participants and Methods: A total of 387 employees and 110 supervising managers participated in the two-wave dyadic survey. To test our hypotheses, we performed the hierarchical regression and conducted bootstrapping analyses to test our hypotheses.Results: Findings indicated that LMX ambivalence not only improves employees’ cognitive flexibility and promotes bootleg innovation, but also aggravates employees’ job anxiety and hinders bootleg innovation. In addition, integrative complexity significantly moderates the above two mediating paths. Specifically, when integrative complexity was higher, the negative mediating effect of job anxiety was attenuated, and the positive mediating effect of cognitive flexibility was enhanced.Conclusion: Contrasting with previous research, this research analyzed the triggering mechanism of bootleg innovation combined with the dynamic interaction of environmental stimulus, emotion and cognition. The findings provide novel insight into how to achieve bootleg innovation.Keywords: LMX ambivalence, bootleg innovation, cognitive flexibility, job anxiety, integrative complexity

To achieve this purpose, the authors proposed a double-chain mediation model in this study.Methods: Data with 342 questionnaires were collected for effective matching between employees and leaders at two time nodes. The hypotheses were validated by structural equation modeling and bootstrap approaches.Results: Results indicate that paradoxical leadership has a significant and positive impact on employees’ bootleg innovation. In addition, psychological capital and thriving at work play a partial mediating role between paradoxical leadership and employees’ bootlegging behaviors respectively and a chain mediating role between the two together. Moreover, there is no significant difference among the three mediating paths.Conclusion: The present research advances our understanding of bootleg innovation with a focus on the specific role of paradoxical leadership. Our findings, and especially those related to the role of psychological capital and thriving at work, reveal the influence mechanisms of paradoxical leadership on employees’ bootleg innovation. At the same time, it is useful for understanding what leadership style can effectively stimulate employees’ bootleg innovation.Keywords: paradoxical leadership, bootleg innovation, psychological capital, thriving at work

Combined with the questionnaires and animal-specific IgE levels, we analyzed the epidemiological characteristics and risk factors of furry animal sensitization in different regions and populations of Chinese Mainland.Results: Among the 2377 patients with suspected allergic diseases, 14.9% were sensitized to cat dander, 9.3% to dog dander and 5.5% to horse dander. Animal allergens mainly cause low-level sensitization (class 1– 3). There was a significant correlation between cat, dog and horse dander allergen sIgE, with correlation coefficients (rs) all greater than 0.750. The majority (46.5%) of sIgE-positive patients were sensitized to at least two animal allergens simultaneously. The prevalence of these animals all showed a trend of increasing first and then decreasing with age, and all reached the peak in young adolescence. As for the geographical factors, the sensitization rate of cats and dogs in Western was significantly higher than that in Eastern (cat: 18.4% vs 9.2%, dog: 11.6% vs 5.5%, all P < 0.001), however, no significant differences were found in horses. Aged ≤ 6 years, living in Western, and high animal allergen exposure elevated the risk of cat or dog sensitization. Living on a lower floor (aOR: 0.56) was a protective factor for horse sensitization.Conclusion: In this representative sample of Chinese patients with suspected allergic diseases, there was an apparent geographic variation in sensitization to cats and dogs. Age factor and living in Western also had a significant impact on animal allergen sensitization rate.Keywords: animal allergen, specific immunoglobulin E, cross-sectional survey, suspected allergic patient

To assess the cytotoxicity caused by the contrast agent; cells were pretreated with different concentrations of baicalin; and then the cells were exposed to iohexol again, and the relevant indicators were tested again.Results: After HK-2 cells were exposed to iohexol, the NLRP3 inflammasome pathway markers NLRP3, interleukin (IL)-1β, and IL-18 mRNA levels as well as the protein expression levels of NLRP3, ASC, Caspase-1, and GSDMD were up-regulated. In addition, the effect also significantly increased the IL-18, IL-1β, lactate dehydrogenase (LDH), superoxide dismutase (SOD), malondialdehyde (MDA) release, and cellular ROS levels. The results of Annexin V-FITC/PI flow cytometry showed that the level of apoptosis was increased. However, after the intervention of baicalin, the changes in the above indexes caused by iohexol stimulation of HK-2 cells were inhibited.Conclusion: Exposure to iohexol can induce pyroptosis of HK-2 cells through the ROS/NLRP3/Caspase-1/GSDMD signaling pathway. Baicalin ameliorated iohexol-induced pyroptosis in HK-2 cells by regulating the NLRP3 inflammasome pathway.Keywords: pyroptosis, baicalin, iohexol, ROS/NLRP3/Caspase-1/GSDMD pathway, kidney injury

Demographic and clinical information was collected, including age, gender, FH (positive or negative, types of cancers, degree of relatives, etc.), pathological diagnosis, and Fuhrman grades.Results: A positive FH of any cancer was observed in 26.5% of the RCC patients, while only 16.8% patients with benign kidney tumor were found to have a positive FH. A strong correlation was observed between FH of any cancers in first-degree relatives and RCC (odds ratio [OR]=4.60, 95% confidence interval [CI]: 1.95– 10.85, P=5.50× 10− 5) or ccRCC (OR=4.63, 95% CI: 1.95– 11.02, P=9.63× 10− 5). In subgroup analysis, FH of digestive cancers was significantly associated with RCC (OR=4.42, 95% CI: 1.35– 14.51, P=0.005) or ccRCC (OR=4.14, 95% CI: 1.25– 13.75, P=6.84× 10− 4). Similar results were found in multivariate analyses.

KRBA1 is a member of the KRAB family and participates in the regulation of gene transcription. However, no studies have focused on the role of KRBA1 in HCC.Patients and Methods: In this study, we first analyzed the expression of KRBA1 in HCC using TCGA and ICGC databases and validated by Immunohistochemistry in clinical HCC samples. The Wilcoxon rank-sum test was used to determine the relationship between KRBA1 expression and clinicopathological features. Subsequently, we used Kaplan-Meier online website analysis and Cox regression model to predict the prognostic value of KRBA1 in HCC patients. Furthermore, the functions of KRBA1 were identified by enrichment analysis. TIMER and GSCALite were used to investigate the relationship between KRBA1 expression in HCC and immune infiltration and drug targets, respectively. Finally, the relationship between KRBA1 expression and m6A modification in HCC was analyzed using the TCGA and ICGA datasets.Results: The results showed that KRBA1 was upregulated in HCC and was associated with many clinicopathological features. High KRBA1 causes poor overall survival and may be an independent risk factor for HCC. KRBA1 tends to be hypermethylated and associated with poor prognosis in HCC compared with normal tissues. Enrichment analysis indicates that KRBA1 is associated with cell cycle and immune processes, and TIMER analysis shows that KRBA1 expression is associated with infiltration levels and immune characteristics of various immune cells. Silenced KRBA1 evidently reduced three chemokine expression in HCC cells. Drug sensitivity analysis showed that KRBA1 was sensitive to 39 drug small molecules. KRBA1 showed a strong positive correlation with five m6A related genes.Conclusion: KRBA1 is a prognostic biomarker associated with HCC immunity and m6a modification, serving as an effective target for the diagnosis and treatment of HCC.Keywords: KRBA1, prognosis, biomarker, immune infiltration, hepatocellular carcinoma, m6A modification

This study evaluated the clinical and imaging features, treatment, and prognosis of patients with recurrent RB with limb bone metastases and without central nervous system involvement.Patients and Methods: The clinical data of five patients with RB with limb bone metastases who were diagnosed at the Department of Pediatrics in Beijing Tongren Hospital between January 2015 and January 2021 were analyzed retrospectively.Results: Three males and two females were included (seven eyes: four group E and one each of group D, C, and B). The most common symptom was pain. Three patients had bone marrow and lymph node metastases. Three patients had single and two had multiple skeletal lesions. The main bones that were involved were the femur, humerus, talus, and ulna. The simultaneous involvement of the bone marrow and cortex was also observed. Serum neuron-specific enolase (NSE) levels were significantly elevated in four cases and slightly elevated in one case; primary intravenous chemotherapy resulted in a decrease in NSE levels and the gradual resolution of the bone lesions. Two patients died at the time of follow-up and three were in complete remission. The results of the statistical analysis showed that anterior chamber invasion was correlated with prognosis, and there was significant difference in the decrease in the serum NSE levels after intravenous chemotherapy.Conclusion: Regular lifelong follow-up of patients with RB is warranted to identify bone metastases earlier.

Mechanical pain threshold (von Frey test) and face grooming behavior were measured in each group. Recovery of demyelination of trigeminal ganglion was observed via electron microscopy 2 weeks later, and BMSC differentiation was observed via immunofluorescence.Results: Rats in the BMSC group exhibited significant improvements in mechanical pain threshold and face grooming behavior compared with the PBS group. BMSCs could repair demyelinating changes in trigeminal ganglion in ION-CCI rats. Only cells expressing GFAP, S-100, and p75 were observed via immunofluorescence, and no PKH67-labeled BMSCs were observed in the trigeminal ganglion. No BMSC differentiation was observed in the trigeminal ganglion.Conclusion: Injection of BMSCs around the trigeminal ganglion could relieve trigeminal neuralgia effectively and repair trigeminal ganglion demyelination. No differentiation of BMSCs injected around the trigeminal ganglion into Schwann cells was observed. The mechanism of trigeminal neuralgia demyelination repair requires further investigation.Keywords: bone marrow mesenchymal stem cells, demyelination, trigeminal neuralgia, treatment

LncRNA HEIH expression in peripheral blood of included subjects was detected using RT-qPCR. According to the median expression of lncRNA HEIH, LUSC and LUAD patients were allocated into lncRNA HEIH high/low expression groups. The correlation between lncRNA HEIH and clinical indicators of patients was analyzed; Logistic multifactor regression was used to analyze the independent risk factors influencing lncRNA HEIH level. Receiver-operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of lncRNA HEIH and carcinoembryonic antigen (CEA) in LUSC/LUAD patients. MedCalc-Comparison of ROC curves was used to compare the area under ROC curve. The cumulative survival rates of lncRNA HEIH high/low expression group were analyzed by Kaplan–Meier curve. COX multivariate analysis was used to assess the independent factors affecting prognosis of NSCLC.Results: LncRNA HEIH in peripheral blood of LUSC/LUAD patients was higher than that in healthy controls, with no evident difference between LUSC and LUAD groups. In LUSC/LUAD patients, TNM stage, lymph node metastasis, distal metastasis, and CEA were independent risk factors affecting lncRNA HEIH; patients with high lncRNA HEIH expression had larger pack-years and tumor size, higher CEA level and tumor stage, and higher risk of lymph node metastasis and distal metastasis. LncRNA HEIH had higher diagnostic efficiency than CEA in NSCLC patients. High expression of lncRNA HEIH predicted poor prognosis in patients with NSCLC and was an independent risk factor for prognosis of NSCLC.Conclusion: High expression of lncRNA HEIH is helpful in the diagnosis of NSCLC and predicts poor prognosis.Keywords: non-small cell lung cancer, long non-coding RNA HEIH, prognosis, carcinoembryonic antigen, lung squamous cell carcinoma, lung adenocarcinoma, peripheral blood

Clinical features, laboratory findings, and fatal outcomes were collected from electronic medical records. Patients were randomly separated into a 70% training set (n=1,353) and a 30% testing set (n=580) for the development and validation of a prediction model. All data within 24 hours of ICU admission were compared between survivors and non-survivors. The risk factors were identified through LASSO and multivariate logistic regression analysis, and then used to develop a predicting nomogram. The nomogram for predicting hospital mortality of ICHs with severe pneumonia in the ICU was validated by C-index, AUC (area under the curve), calibration curve, and Decision Curve Analysis (DCA).Results: Eight risk factors, including age, fever, dyspnea, chronic renal disease, platelet counts, neutrophil counts, PaO2/FiO2 ratio, and the requirement for vasopressors, were adopted in a nomogram for predicting hospital mortality. The nomogram had great predicting accuracy with a C-index of 0.819 (95% CI=0.795– 0.842) in the training set, and a C-index of 0.819 (95% CI=0.783– 0.855) in the testing set for hospital mortality. Additionally, the nomogram had well-fitted calibration curves. DCA demonstrated that the nomogram was clinically beneficial.Conclusion: This study developed a novel nomogram for predicting hospital mortality of ICHs with severe pneumonia in the ICU. Validation showed good discriminatory ability and calibration, indicating that the nomogram was expected to be a superior predictive tool for doctors to identify risk factors and predict mortality, and might be generally applied in clinical practice after more external validations.Keywords: immunocompromised, severe pneumonia, ICU, risk factors, nomogram

This study investigated the influences of age, driving experience and other covariates on aggressive driving behavior.Methods: A cross-sectional survey was conducted in Yixing City, Wuxi City, Jiangsu Province, China. Regression analysis was applied to explore the influences of age and driving experience and their interactions with other covariates on aggressive driving behavior. Two analyses methodologies were used to assess the simple effect of the interactions. Firstly, the Jamovi automatic analysis classification program was used to calculate the simple slope test. Second, the SPSS macro program was also used to calculate the simple slope test also.Results: A total of 570 drivers (247 males, 282 females) participated in the survey. A negative correlation was found between age and aggressive driving behaviors, and a positive correlation was found between neuroticism and aggressive driving behaviors in the multiple regression analysis. Significant associations were also found between age, driving experience, and depression, as well as age, driving experience, and neuroticism. Simple slope tests showed that depressive symptoms could increase aggressive behaviors in the elderly and experienced drivers. When experiencing neuroticism, individuals with higher driving experience were more aggressive in driving than shorter experienced drivers.Conclusion: Age and neuroticism influenced aggressive driving behaviors. Veteran drivers could be aggressive drivers when experiencing depressive symptoms or neuroticism. Mobile intervention could be sent to the potentially risky drivers, which would be safe and broadly feasible to prevent aggressive driving behavior in the background of COVID-19.Keywords: aggressive driving behavior, age, driving experience, depressive symptoms, neuroticism

We analyzed the factors for post-remission recurrence in children with neuroblastoma through a retrospective study.Methods: A total of 179 children with neuroblastoma who achieved initial complete response were included in this study. Kaplan–Meier method and multivariate Cox regression model were used to assess the factors that may have impact on tumor recurrence after complete response.Results: The 5-year overall survival rates of the entire cohort (n = 179), recurrence group (n = 86) and non-recurrence group (n = 93) were 81.9%, 66.2%, and 98.7%, respectively. The 5-year recurrence-free survival (RFS) rates of the entire cohort and the high-risk cohort were 47.3% and 31.2%, respectively. RFSs were significantly reduced in children with age ≥ 18 months, INSS stage 4, unfavorable histology, bone marrow metastasis, osseous metastasis, serum NSE level ≥ 100 ng/mL, and serum LDH level ≥ 1400 U/L (P < 0.05). The independent risk factors for post-remission recurrence in the entire cohort were age ≥ 18 months, unfavorable histology, and serum LDH level ≥ 1400 U/L (P < 0.05). In the high-risk cohort, the independent risk factor for recurrence was serum LDH ≥ 1400 U/L (P < 0.05). Based on a new recurrence risk stratification, the 5-year RFSs of the children were 93.5%, 66.4%, and 22.5% in the low-risk, intermediate-risk, and high-risk groups, respectively. The area under the ROC curve of the new stratification was 0.773 (95% CI: 0.704− 0.842).Conclusion: Age ≥ 18 months, unfavorable histology, and serum LDH level ≥ 1400 U/L are independent risk factors for post-remission recurrence in children with neuroblastoma. A newly established recurrence risk stratification has diagnostic advantages in predicting risk of recurrence, which is especially suitable for low- and middle-income countries or regions.Keywords: age, MYCN amplification, histology, recurrence-free survival, serum lactate dehydrogenase, serum neuron-specific enolase

However, the relationship between sleep duration and the concentration of the protein klotho in the serum remains unknown in the general population of the United States. Hence, this study aimed at exploring the association between them.Methods: Participants whose data included klotho protein and sleep duration variables in the National Health and Nutrition Examination Survey data from 2007 to 2016 were utilized for this analysis.Results: Sleep duration was non-linearly associated with the level of klotho protein in the serum, with a negative association between sleep duration and serum klotho concentration after adjusting for confounding variables (β = − 7.6; 95% CI: − 11.3, − 4.0; P < 0.001). The conversion of the sleep duration from a continuous variable to a categorical variable (tertile: T1: < 5.5 hours; T2: 5.5– 7.5 hours; T3: > 7.5 hours) revealed that the serum klotho of the participants in the highest tertile (> 7.5 hours) was 21.9 pg/mL lower (95% CI: − 38.6, − 5.2; P = 0.01) than those in the lowest tertile (< 5.5 hours).Conclusion: Our results revealed that people who sleep more than 7.5 hours per night have decreased levels of the anti-aging protein klotho in their serum, thus being more at risk of aging-related syndromes.Keywords: klotho protein, sleep duration, aging, NHANES

A total of 762 children participated in this survey. To evaluate the risk factors and specific sensitization patterns of clinical AR through questionnaires and specific immunoglobulin E to 11 aeroallergens.Results: Of the 762 patients, 593 (77.8%) had at least one positive IgE level. Aged 7– 14 years (OR 1.503, (95% CI 1.058– 2.136), P = 0.023); With allergic conjunctivitis (OR 1.843, (95% CI 1.297– 2.620), P = 0.001) and living in the Eastern (OR 1.802, (95% CI 1.263– 2.573), P = 0.001) all elevated the risk of clinical AR associated with aeroallergens. The sensitization rates of D. pteronyssinus and D. farinae were higher than those of other allergens in the 0– 6 and 7– 14 years old age groups. The most common aeroallergens among self-reported children with AR in the eastern were D. farinae (74.9%) and D. pteronyssinus (74.3%), while in the western were mugwort (60.0%) and marguerite (56.6%). Majority of sIgE-positive subjects were sensitized to three or more of the tested pollen allergens in the Western (52.1%), compared with 5.7% in the Eastern.Conclusion: There was an apparent geographic variation in childhood allergies in China. Age factors also had strong impacts on the allergen sensitization rate of children, but these impacts differed across regions.Keywords: allergic rhinitis, specific immunoglobulin E, cross-sectional survey, aeroallergen, children

Therefore, a simple and easy screening method for recognizing and predicting MCI is urgently needed. The study aimed to establish machine learning models of retinal vascular features to categorize and predict MCI.Patients and Methods: Subjects enrolled underwent cognitive function assessment and were divided into a normal group, an MCI group, and a dementia group, and fundus photography was performed. MATLAB 2019b was used for fundus image preprocessing and vascular segmentation. Via the Green channel, adaptive histogram equalization (AHE), image binarization, and median filtering, we obtained the original and segmentation retinal vessel images. Afterwards, the histogram of oriented gradient (HOG) was used for image feature extraction. Support vector machine (SVM) and extreme learning machine (ELM) were selected for training models in the fundus original images and fundus vascular segmentation images, respectively. Among the three cognitive groups, sensitivity, specificity, the receiver operating characteristic (ROC) curves, and the area under the curve (AUC) were used to evaluate and compare the predictive performance of the two models in the fundus original and vascular segmentation images, respectively.Results: A total of 86 eligible subjects were enrolled in the study. After a clinical cognitive assessment, the participants were divided into the normal group (N = 38), the MCI group (N = 26), and the dementia group (N = 22). A total of 332 qualified fundus images were adopted after screening. Comparing the models among the three groups showed that the SVM model had more advantages than the ELM model in the fundus original images and vascular segmentation images. Meanwhile, we found that the original images performed better than the segmentation images in the same prediction model. Among the three groups, the SVM model of the fundus original images had the best performance.Conclusion: The establishment of a predictive model based on vascular-related feature extraction from fundus images has high recognition and prediction abilities for cognitive function and can be used as a screening method for MCI.Clinical Trial Registration: ChiCTR.org.cn (ChiCTR1900027404), Registered on Nov 12, 2019.Keywords: retinal imaging techniques, mild cognitive impairment, machine learning, support vector machine, extreme learning machine

However, the relationship between selenoprotein P (SeP), mRNA (SELENOP mRNA) and tumorigenesis remains unclear. Plasma SeP transports Se to various target tissues and has antioxidant characteristics. The present study aimed to explore the multifaceted pan-cancer properties of SELENOP in terms of its tissue-specific expression, prognostic value, immune function, and signaling pathway enrichment.Patients and Methods: The expression profile of SELENOP was determined in 33 tumor types and survival, pathway enrichment, and correlation analyses were conducted based on TCGA database. The relationship between SELENOP expression and immune infiltration and macrophage subtype gene markers was investigated using the TIMER and GEPIA.Results: SELENOP gene expression was decreased in many cancer tissues, but was upregulated in brain lower grade glioma (LGG). Furthermore, SELENOP expression was associated with a better prognosis in most cancers, but a poorer prognosis in LGG and uterine corpus endometrioid carcinoma (UCEC). Our results showed that SELENOP was correlated with infiltration level of six immune cell types, where SELENOP also showed a strong correlation with macrophages in some cancer types. However, we failed to determine macrophage polarization in 33 tumor types. SELENOP negatively regulated vascular endothelial cell proliferation in LGG and UCEC and epidermal cell differentiation in six tumor types. In contrast, upregulation was related to immune function, including T cell activation, B cell-mediated immunity, adaptive immune response and immune response regulation cell surface receptor signaling pathways in another six tumor types.Conclusion: These findings highlighted the tissue-specific expression, prognostic value and immune characteristics of SELENOP in pan-cancer, and provided insights for illustrating the role of SELENOP in tumorigenesis.Keywords: selenoprotein P, pan-cancer, immune infiltration, prognosis, tissue-specific expression
