Abstract This article examines the crucial role of early childhood teachers in China’s ongoing curriculum reforms by addressing two key questions: (1) how teachers interact with the curriculum reform cycle, and (2) what specific roles they play within the reforms. We synthesize literature on early childhood teachers’ involvement in China’s curriculum reforms and provide insights for future improvements in teachers’ status. Our analysis reveals that teachers contribute to establishing curricular goals, selecting content, and implementing instructional methods. However, they lack formal roles in setting educational goals and face limitations due to administrative decisions and societal expectations. Their knowledge and experience are often underutilized. Based on these findings, we propose increased teacher training to enhance their capacity and contribution, and improved policies for teacher recruitment, retention, and empowerment.

Abstract Background Previous research has revealed the potential impact of circadian rhythms on pulmonary diseases; however, the connection between circadian rhythm-associated Thyrotroph Embryonic Factor (TEF) and Pulmonary Arterial Hypertension (PAH) remains unclear. We aim to assess the genetic causal relationship between TEF and PAH by utilizing two sets of genetic instrumental variables (IV) and publicly available Pulmonary Arterial Hypertension Genome-Wide Association Studies (GWAS). Methods Total of 23 independent TEF genetic IVs from recent MR reports and PAH GWAS including 162,962 European individuals were used to perform this two-sample MR study. Gain- and loss-of-function experiments were used to demonstrate the role of TEF in PAH. Results Our analysis revealed that as TEF levels increased genetically, there was a corresponding increase in the risk of PAH, as evidenced by IVW (OR = 1.233, 95% CI: 1.054–1.441; P = 0.00871) and weighted median (OR = 1.292, 95% CI for OR: 1.064–1.568; P = 0.00964) methods. Additionally, the up-regulation of TEF expression was associated with a significantly higher likelihood of abnormal circadian rhythm (IVW: P = 0.0024733, β = 0.05239). However, we did not observe a significant positive correlation between circadian rhythm and PAH (IVW: P = 0.3454942, β = 1.4980398). In addition, our in vitro experiments demonstrated that TEF is significantly overexpressed in pulmonary artery smooth muscle cells (PASMCs). And overexpression of TEF promotes PASMC viability and migratory capacity, as well as upregulates the levels of inflammatory cytokines. Conclusion Our analysis suggests a causal relationship between genetically increased TEF levels and an elevated risk of both PAH and abnormal circadian rhythm. Consequently, higher TEF levels may represent a risk factor for individuals with PAH.

Abstract Background Acute monocytic leukemia-M5 (AML-M5) remains a challenging disease due to its high morbidity and poor prognosis. In addition to the evidence mentioned earlier, several studies have shown that programmed cell death (PCD) serves a critical function in treatment of AML-M5. However, the role and relationship between ferroptosis and necroptosis in AML-M5 remains unclear. Methods THP-1 cells were mainly treated with Erastin and IMP-366. The changes of ferroptosis and necroptosis levels were detected by CCK-8, western blot, quantitative real-time PCR, and electron microscopy. Flow cytometry was applied to detect the ROS and lipid ROS levels. MDA, 4-HNE, GSH and GSSG were assessed by ELISA kits. Intracellular distribution of FSP1 was studied by immunofluorescent staining and western blot. Results The addition of the myristoylation inhibitor IMP-366 to erastin-treated acute monocytic leukemia cell line THP-1 cell not only resulted in greater susceptibility to ferroptosis characterized by lipid peroxidation, glutathione (GSH) depletion and mitochondrial shrinkage, as the FSP1 position on membrane was inhibited, but also increased p-RIPK1 and p-MLKL protein expression, as well as a decrease in caspase-8 expression, and triggered the characteristic necroptosis phenomena, including cytoplasmic translucency, mitochondrial swelling, membranous fractures by FSP1 migration into the nucleus via binding importin α2. It is interesting to note that ferroptosis inhibitor fer-1 reversed necroptosis. Conclusion We demonstrated that inhibition of myristoylation by IMP-366 is capable of switching ferroptosis and ferroptosis-dependent necroptosis in THP-1 cells. In these findings, FSP1-mediated ferroptosis and necroptosis are described as alternative mechanisms of PCD of THP-1 cells, providing potential therapeutic strategies and targets for AML-M5.

Abstract The potential brain mechanism underlying resilience to socially transferred allodynia remains unknown. Here, we utilize a well-established socially transferred allodynia paradigm to segregate male mice into pain-susceptible and pain-resilient subgroups. Brain screening results show that ventral tegmental area glutamatergic neurons are selectively activated in pain-resilient mice as compared to control and pain-susceptible mice. Chemogenetic manipulations demonstrate that activation and inhibition of ventral tegmental area glutamatergic neurons bi-directionally regulate resilience to socially transferred allodynia. Moreover, ventral tegmental area glutamatergic neurons that project specifically to the nucleus accumbens shell and lateral habenula regulate the development and maintenance of the pain-resilient phenotype, respectively. Together, we establish an approach to explore individual variations in pain response and identify ventral tegmental area glutamatergic neurons and related downstream circuits as critical targets for resilience to socially transferred allodynia and the development of conceptually innovative analgesics.

Abstract Background Sarcopenia is a potential risk factor for adverse outcomes in haematopoietic cell transplantation (HSCT) recipients. We aimed to explore longitudinal body changes in muscle and adipose mass and their prognostic value in allogeneic HSCT‐treated severe aplastic anaemia (SAA) patients. Methods We retrospectively analysed consecutive SAA patients who underwent allogeneic HSCT between January 2017 and March 2022. Measurements of pectoral muscle and corresponding subcutaneous fat mass were obtained via chest computed tomography at baseline and at 1 month, 3 months, 6 months, and 12 months following HSCT. Sarcopenia was defined as pectoral muscle index (PMI) lower than the sex‐specific median at baseline. Changes in body composition over time were evaluated by generalized estimating equations. Cox regression models were used to investigate prognostic factors affecting overall survival (OS) and failure‐free survival (FFS). A nomogram was constructed from the Cox regression model for OS. Results We included 298 adult SAA patients (including 129 females and 169 males) with a median age of 31 years [interquartile range (IQR), 24–39 years] at baseline. Sarcopenia was present in 148 (148/298, 50%) patients at baseline, 218 (218/285, 76%) patients post‐1 month, 209 (209/262, 80%) patients post‐3 month, 169 (169/218, 78%) patients post‐6 month, and 129 (129/181, 71%) patients post‐12 month. A significant decrease in pectoral muscle mass was observed in SAA patients from the time of transplant to 1 year after HSCT, and the greatest reduction occurred in post 1–3 months (P

This study was to evaluate the effect of supplementing the diet of broilers with Neolamarckia cadamba leaf extract (NCLE) on meat quality by evaluating antioxidant parameters and the expression of genes in the p38 mitogen-activated protein kinase/nuclear factor-erythroid 2-related factor 2/antioxidant responsive element (p38 MAPK/Nrf2/ARE) signaling pathway, coupled with LC–MS-based metabolomic analysis. A total of 480 one-day-old male broilers were randomly allocated to four treatment groups—a control (CON) group, which was fed a basal diet, and three NCLE treatment groups, which were fed the basal diet supplemented with 100, 200, or 400 mg/kg NCLE (N1, N2, and N3 groups, respectively) for 42 d. Compared with the CON group, meat quality was improved in the N2 and N3 groups, as evidenced by the higher pH45min (P

Background: Hereditary hemorrhagic telangiectasia (HHT) is an uncommon autosomal dominant condition. The combination of pregnancy and HHT can exacerbate pulmonary hypertension (PH) and, in severe cases, lead to fatality. Case presentation: The case we presented is a 28-year-old multiparous woman. She developed chest tightness and dyspnea in the second trimester of pregnancy, which was not taken seriously at that time, and the symptoms worsened postpartum. Echocardiography showed elevated pulmonary artery pressure (PAP) and the computerized tomographic pulmonary angiogram revealed a significant pulmonary arteriovenous malformation. The patient's condition continued to deteriorate despite treatment to reduce pulmonary hypertension. We reviewed and updated the history of omission, recurrent epistaxis during pregnancy, and similar symptoms running in her family. Combined with the whole exon genetic testing report revealing the ACVRL1 gene mutation at chr12:52308295, the diagnosis of HHT was established. Four months later, a transcatheter closure of the pulmonary arteriovenous fistula was performed, with satisfying outcomes presenting a decrease of more than 15 mmHg in the pulmonary artery pressure. As of right now, the patient's status is stable during the outpatient follow-up. Conclusions: HHT is a rare condition that typically occurs alongside abnormal communication between pulmonary veins and arteries, leading to a high-flow state in the pulmonary circulation. A pulmonary hypertension crisis can also be triggered by the patient's pregnancy, which further increases blood volume.

Abstract The research employed network toxicology and molecular docking techniques to systematically examine the potential carcinogenic effects and mechanisms of aspartame (l-α-aspartyl-l-phenylalanine methyl ester). Aspartame, a commonly used synthetic sweetener, is widely applied in foods and beverages globally. In recent years, its safety issues, particularly the potential carcinogenic risk, have garnered widespread attention. The study first constructed an interaction network map of aspartame with gastric cancer targets using network toxicology methods and identified key targets and pathways. Preliminary validation was conducted through microarray data analysis and survival analysis, and molecular docking techniques were employed to further examine the binding affinity and modes of action of aspartame with key proteins. The findings suggest that aspartame has the potential to impact various cancer-related proteins, potentially raising the likelihood of cellular carcinogenesis by interfering with biomolecular function. Furthermore, the study found that the action patterns and pathways of aspartame-related targets are like the mechanisms of known carcinogenic pathways, further supporting the scientific hypothesis of its potential carcinogenicity. However, given the complexity of the in vivo environment, we also emphasize the necessity of validating these molecular-level findings in actual biological systems. The study introduces a fresh scientific method for evaluating the safety of food enhancers and provides a theoretical foundation for shaping public health regulations.

Abstract Aims Caregivers rate improved communication ability as one of the most desired outcomes for successful interventions for individuals with Angelman syndrome (AS). When measuring communication ability in clinical trials, the reliability of such measures is critical for detecting significant changes over time. This study examined the reliability of the Observed-Reported Communication Ability (ORCA) measure completed by caregivers of individuals with AS. Methods The ORCA measure was completed by 249 caregivers with 170 caregivers completing the ORCA measure again after 5–12 days. Generalizability theory was used to examine the following sources of measurement error in ORCA scores: concepts, subdomains, assessment points, and the interactions among those facets and the object of measurement: communication ability. Three generalizability studies were conducted to understand the reliability of the ORCA measure for different measurement designs. Decision studies were carried out to demonstrate the optimization of measurement procedures of the ORCA measure. Results G and Phi coefficients of the original measurement design exceeded the 0.80 threshold considered sufficiently reliable to make relative and absolute decisions about the communication ability of individuals with AS based on their caregivers’ observed scores. The optimization procedures indicated that increasing the number of communication concepts and/or assessment points leads to more reliable estimates of communication. Conclusion The ORCA measure was able to reliably distinguish different levels of communication ability among individuals with AS. Multiple assessment points and or more concepts would provide more precise estimates of an individual’s communication ability but at the cost of survey fatigue.

Abstract Background Social communication impairments (SCI) is a core symptom of autism spectrum disorder (ASD) and is marked by challenges in social interaction. Although physical exercise has been shown to improve SCI, this finding has not been supported by comprehensive scientific evidence. Existing research has established a strong link between the SCI in children with ASD and abnormalities in regional homogeneity (ReHo). Therefore, investigating the effects of physical exercise on SCI and Reho in patients with ASD may help to elucidate the neurological mechanisms involved. Methods The present study included 30 preschool children diagnosed with ASD, with 15 participants in each group (experimental and control). The experimental group underwent a 12-week mini-basketball training program (MBTP) based on routine behavioral rehabilitation, while the control group only received routine behavioral rehabilitation. The Social Responsiveness Scale-Second Edition (SRS-2) was employed to assess SCI in both groups. Resting-state functional magnetic resonance imaging technology was used to evaluate ReHo in both groups. Results After 12-week of MBTP, significant group × time interactions were observed between the experimental and control groups in total SRS-2 scores (F = 14.514, p < 0.001, η p 2 = 0.341), as well as in the domains of social cognition (F = 15.620, p < 0.001, η p 2 = 0.358), social communication (F = 12.460, p < 0.01, η p 2 = 0.308), and autistic mannerisms (F = 9.970, p < 0.01, η p 2 = 0.263). No statistical difference was found in the scores for the social awareness subscale and social motivation subscale in the group × time interaction (all p > 0.05). The experimental group exhibited increased ReHo in the right Cerebellum_Crus1 and right parahippocampal gyrus, coupled with decreased ReHo in the left middle frontal gyrus (orbital part), left superior frontal gyrus (dorsolateral), left postcentral gyrus, and right superior parietal gyrus. Furthermore, a decrease in ReHo in the left postcentral gyrus positively correlated with changes in social communication scores in SCI behaviors (p < 0.05). Conclusions Our study underscores the effectiveness of a 12-week MBTP in ameliorating SCI and abnormalities in ReHo among preschool children with ASD. Trial registration The trial is retrospectively registered on the Chinese Clinical Trial Registry (ChiCTR1900024973; August 5, 2019).

Abstract Little is known about the relationships between human genetics and the airway microbiome. Deeply sequenced airway metagenomics, by simultaneously characterizing the microbiome and host genetics, provide a unique opportunity to assess the microbiome-host genetic associations. Here we performed a co-profiling of microbiome and host genetics with the identification of over 5 million single nucleotide polymorphisms (SNPs) through deep metagenomic sequencing in sputum of 99 chronic obstructive pulmonary disease (COPD) and 36 healthy individuals. Host genetic variation was the most significant factor associated with the microbiome except for geography and disease status, with its top 5 principal components accounting for 12.11% of the microbiome variability. Within COPD individuals, 113 SNPs mapped to candidate genes reported as genetically associated with COPD exhibited associations with 29 microbial species and 48 functional modules (P

Background This randomised controlled study was aimed at investigating the effects of WeChat-based cognitive behavioural stress management (WB-CBSM) on the mental health of patients with early-stage cervical cancer treated with surgical resection.Methods A total of 184 patients with early-stage cervical cancer were randomised to receive either WB-CBSM (n = 92) or normal care (NC) (n = 92) for 8 weeks.Results Compared with the NC group, the WB-CBSM group exhibited reduced Hospital Anxiety and Depression Scale (HADS)–anxiety scores at months (M)1 (t = 2.022, P = 0.045), M3 (t = 2.575, P = 0.011), and M6 (t = 2.709, P = 0.007); anxiety rates at M3 (χ2 = 4.834, P = 0.028) and M6 (χ2 = 5.182, P = 0.023); HADS–depression scores at M3 (t = 2.069, P = 0.040) and M6 (t = 2.449, P = 0.015); and depression rates at M6 (χ2 = 4.268, P = 0.039). Moreover, the WB-CBSM group showed increased Functional Assessment of Chronic Illness Therapy–Spiritual Well-Being scale scores at M1 (t = −2.001, P = 0.047), M3 (t = −2.281, P = 0.024), and M6 (t = −3.501, P = 0.001); the Quality of Life Questionnaire-Core 30 (QLQ-C30) global health score at M3 (t = −2.034, P = 0.043) and M6 (t = −2.426, P = 0.016); and QLQ-C30 function score at M3 (t = −2.009, P = 0.046). However, the groups exhibited decreased EuroQol-5 dimension scores at M3 (t = 2.056, P = 0.041) and M6 ((t = 2.242, P = 0.026) and QLQ-C30 symptom scores at M1 (t = 2.026, P = 0.044) and M3 (t = 2.210, P = 0.028).Conclusion WB-CBSM reduced anxiety and depression and improved the spiritual well-being and quality of life of patients with early-stage cervical cancer treated with surgical resection.

AbstractBackground While Cardiac Rehabilitation (CR) programs have shown effectiveness in improving cardiac outcomes, there is limited understanding of how patients perceive and adapt to these interventions. Furthermore, alternative modes of delivering CR that have received positive evaluations from participants remain underexplored, yet they have the potential to enhance CR uptake.Objectives To explore the patient experience in CR programmes following Acute Myocardial Infarction (AMI) and describe their adaptive processing.Patients and Methods This qualitative study was conducted at a nationally certified centre in China between July 2021 and September 2022, encompassing three stages: in-hospital, centre-based, and home-based CR programs. Purposive sampling was used to select eligible AMI patients for in-depth semi-structured interviews. The interview outline and analytical framework were aligned with the key concepts derived from the middle-range theory of adaptation to chronic illness and the normalization process theory. The findings were reported following the Consolidated Criteria for Reporting Qualitative Research checklist.Results Forty AMI patients were recruited. Four main themes describing the process of AMI patients normalizing CR intervention were identified, including (1) experiencing CR service driving by role’s responsibilities, (2) engaging in collaborative relationship based on interpersonal trust, (3) exploring a personalized rehabilitation plan by complex integration, and (4) expecting a promised outcome to shape decision-making.Conclusion Integrated care interventions for AMI patients could benefit from a collaborative co-designed approach to ensure that CR interventions are normalized and fit into patients’ daily lives. Organizational-level CR services should align with the rehabilitation needs and expectations of patients.

Ammonium salt vanadium precipitation process has excellent performance in industrial production, but its shortcomings such as high cost and environmental impact are not conducive to sustainable development. In this paper, ethylenediamine was selected as the precipitant, and vanadate was precipitated from acidic simulated vanadium-rich solutions by the ammonium salt precipitation process. The high purity V2O5 product was obtained after calcination. Under optimal conditions, the precipitation rate of vanadium reached 94.8 %, and the purity of vanadium was as high as 99.1 %. The vanadium precipitation product was hexamethyl ammonium, and the vanadium product was V2O5. It can be derived by the differential method that the reaction order was n = 2.4, the reaction rate equation was CV-1.4=kt+a, and the apparent activation energy was 27.8097 kJ/mol, which can be classified as the diffusion-controlled reaction. This innovative process enables a savings of 5050 yuan per ton of V2O5. On this basis, a complete V2O5 production process with zero waste discharge was designed.

We assessed the psychometric properties of the “providing validation” subscale of PedCOM measures for parents of children with vascular anomalies and adult patients. A total of 139 adult patients and 78 parents completed surveys. The mean score for patients was 3.7 (standard deviation 1.0), and for parents was 4.0 (standard deviation 0.9). “Providing validation” measures demonstrated high internal consistency and good model fit to a unidimensional model for both patients and parents using confirmatory factor analysis. The measures also demonstrated convergent validity with co-administered measures. This study demonstrated the validity of “providing validation” measures for parents and adult patients with vascular anomalies.

Abstract Alzheimer’s disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia in the elderly worldwide. The exact etiology of AD, particularly its genetic mechanisms, remains incompletely understood. Traditional genome-wide association studies (GWAS), which primarily focus on single-nucleotide polymorphisms (SNPs) with main effects, provide limited explanations for the “missing heritability” of AD, while there is growing evidence supporting the important role of epistasis. In this study, we performed a genome-wide SNP–SNP interaction detection using a linear regression model and employed multiple GPUs for parallel computing, significantly enhancing the speed of whole-genome analysis. The cerebrospinal fluid (CSF) phosphorylated tau (P-tau)/amyloid- $$\beta _{42}$$ β 42 (A $$\beta _{42}$$ β 42 ) ratio was used as a quantitative trait (QT) to enhance statistical power. Age, gender, and clinical diagnosis were included as covariates to control for potential non-genetic factors influencing AD. We identified 961 pairs of statistically significant SNP–SNP interactions, explaining a high-level variance of P-tau/A $$\beta _{42}$$ β 42 level, all of which exhibited marginal main effects. Additionally, we replicated 432 previously reported AD-related genes and found 11 gene–gene interaction pairs overlapping with the protein-protein interaction (PPI) network. Our findings may contribute to partially explain the “missing heritability” of AD. The identified subnetwork may be associated with synaptic dysfunction, Wnt signaling pathway, oligodendrocytes, inflammation, hippocampus, and neuronal cells.

Abstract This cross-sectional study aims to investigate the prevalence and causes of visual impairment (VI) and blindness in Jiangsu Province, China in 2022 during the COVID-19 pandemic. Participants (n = 13,208, aged 18–93) underwent comprehensive ocular examinations. The prevalence and causes of binocular VI (presenting visual acuity [VA] ≥ 20/400 and

Abstract Diabetic nephropathy (DN), one of the more prevalent microvascular complications in patients diagnosed with diabetes mellitus, is attributed as the main cause of end-stage renal disease (ESRD). Lipotoxicity in podocytes caused by hyperglycemia has been recognised as a significant pathology change, resulting in the deterioration of the glomerular filtration barrier. Research has demonstrated how dapagliflozin, a kind of SGLT2i, exhibits a multifaceted and powerful protective effect in DN, entirely independent of the hypoglycemic effect, with the specific mechanism verified. In this present study, we found that dapagliflozin has the potential to alleviate apoptosis and restore cytoskeleton triggered by high glucose (HG) in vivo and in vitro. We also discovered that dapagliflozin could mitigate podocyte cholesterol accumulation by restoring the expression of ABCA1, which is the key pathway for cholesterol outflows. This research also mechanistically demonstrates that the protective effect of dapagliflozin can be mediated by KLF-5, which is the upstream transcription factor of ABCA1. Taken together, our data suggest that dapagliflozin offers significant potential in alleviating podocyte injury and cholesterol accumulation triggered by high glucose. In terms of the mechanism, we herein reveal that dapagliflozin could accelerate cholesterol efflux by restoring the expression of ABCA1, which is directly regulated by KLF-5.

Abstract Background The purpose of this study was to evaluate relationships between demographics, professional characteristics, and perceived challenges facing the specialty of anesthesiology among physicians who entered a fellowship and those who started independent practice immediately after finishing a U.S. anesthesiology residency. Methods Anesthesiologists in the year after their residency graduation were invited to take an online survey during the academic years of 2016–2017, 2017–2018, and 2018–2019, with questions about their personal characteristics, the nature of their professional lives, and their perceptions of the greatest challenge facing the profession of anesthesiology. Results A total of 884 fellows-in-training and 735 anesthesiologists starting independent practice right after the completion of their residency responded. Fellows were slightly younger (mean = 33.2 vs. 34.0 years old, p

Objectives: During the COVID-19 pandemic, there was a decline in vaccine coverage, and the implementation of combined vaccines and co-administration strategies emerged as potential solutions to alleviate this predicament. Our objective is to delve into the concurrent administration of the sabin-strain-based inactivated poliovirus vaccine (sIPV), the diphtheria-tetanus-acellular pertussis vaccine (DTaP), and measles-mumps-rubella vaccine (MMR), with the intention of bridging the evidentiary gap pertaining to vaccine co-administration in Chinese infants, and to ensure a safe and effective vaccination strategy, ultimately leading to an augmentation in immunization coverage. Methods: This study was a follow-up trial of the “Immunogenicity and safety of concomitant administration of the sIPV with the DTaP vaccine in children: a multicenter, randomized, non-inferiority, controlled trial.” Blood samples were collected on day 0 and day 30, and serum antibody levels were detected to measure antibody responses to each of the antigens. Local and systemic adverse events were monitored and compared among groups. This study is the first to fill the knowledge gap in China regarding the safe and effective combined vaccination of sIPV, DTaP, and MMR vaccines. Results: The geometric mean titer of the poliovirus types I, II, and III neutralizing antibodies were 1060.22 (95% CI: 865.73-1298.39), 1537.06 (95% CI: 1324.27-1784.05), and 1539.10 (95% CI: 1296.37-1827.29) in group I on day 30; geometric mean titer of antibodies against DTaP and MMR in the simultaneous vaccination group was non-inferior to those in the DTaP alone and MMR alone group. Reporting rates of local and systemic adverse reactions were similar between groups and no serious adverse events were reported throughout the clinical study period. Conclusion: Co-administration of the sIPV, DTaP, and MMR was safe and did not impact immunogenicity, which would help to mitigate administrative costs and enhance vaccine coverage rates.

This study aimed to explore the relationship between motor skill learning and executive function (EF), with an emphasis on the potential effects of football juggling learning. A randomized controlled trial involving 111 participants aged 17–19 years was conducted. Participants were randomly assigned to either the football juggling learning (FJL) group or a control group. The FJL group underwent 70 sessions of football juggling learning, while the control group engaged in their normal daily activities without any exercise intervention during the same time frame. Both groups were assessed for EF performance and underwent functional magnetic resonance imaging (fMRI) scans before and after the experiment. The executive function test included three tasks, namely, inhibition, working memory, and shifting. The results showed significant improvement in inhibition and shifting in both groups, and the FJL group showed greater improvement in these aspects of EF compared to the control group. Additionally, in comparison to the control group, the FJL group exhibited increased functional connectivity within the frontal, temporal, and cerebellar regions from the pre-test to the post-test. Notably, enhanced functional connectivity between the right superior temporal gyrus (posterior division) and left cerebellum 6 was identified in the FJL group and was associated with improved EF performance induced by football juggling learning. These findings shed light on the potential causal relationship between motor skill learning, EF, and brain plasticity. Importantly, our study provides preliminary evidence supporting the use of motor skill learning, such as football juggling, as a potential avenue for cognitive enhancement.

Based on the analytic hierarchy process, an evaluation index system consisting of 3 first-level indexes and 15 second-level indexes was established. The tracking evaluation of marine environmental impact during construction was carried out in three offshore wind farms in Zhuhai, Yangjiang and Shantou, using the evaluation method based on data analysis, which was the first application in this field. The evaluation content covered the qualitative analysis of the environmental management status of the offshore wind power project during the construction period and the implementation of environmental countermeasures as well as the quantitative evaluation of the ecological environmental impact. The comprehensive evaluation results were obtained, and the existing problems and countermeasures were clarified. At the same time, it was suggested to explore the implementation of the whole process of marine environmental impact assessment system, further reduced the impact of engineering construction on the marine environment, and jointly promoted high-quality economic development and high-level protection of ecological environment.

Aromaticity, in general, can promote a given reaction by stabilizing a transition state or a product via a mobility of π electrons in a cyclic structure. Similarly, such a promotion could be also achieved by destabilizing an antiaromatic reactant. However, both aromaticity and transition states cannot be directly measured in experiment. Thus, computational chemistry has been becoming a key tool to understand the aromaticity-driven reaction mechanisms. In this review, we will analyze the relationship between aromaticity and reaction mechanism to highlight the importance of density functional theory calculations and present it according to an approach via either aromatizing a transition state/product or destabilizing a reactant by antiaromaticity. Specifically, we will start with a particularly challenging example of dinitrogen activation followed by other small-molecule activation, CF bond activation, rearrangement, as well as metathesis reactions. In addition, antiaromaticity-promoted dihydrogen activation, CO2 capture, and oxygen reduction reactions will be also briefly discussed. Finally, caution must be cast as the magnitude of the aromaticity in the transition states is not particularly high in most cases. Thus, a proof of an adequate electron delocalization rather than a complete ring current is recommended to support the relatively weak aromaticity in these transition states.

Background: Lipid metabolism disorder appears to be one of the early features of alcoholic liver disease (ALD), which can be speculated via omics analysis including liver transcriptomics and gut microbiota. A complex consisting of the roots of Pueraria lobata and dried fruits of Prunus mume (PPC), which possesses hepatoprotective effects, could serve as a drug or functional food. The lack of non-polysaccharide compounds in PPC with their moderation effects on gut microbiota suggests the necessity for a relevant study. Methods: Six groups of Kunming mice (control, Baijiu injury, silybin, low, medium, and high) were modelled by gavage with Baijiu (for 14 days) and PPC (equivalent to a maximum dose of 9 g/kg in humans). The liver transcriptome data were analyzed to predict gene annotation, followed by the verification of gut microbiota, serum, tissue staining, immunohistochemistry, and Western blotting. Liquid chromatography-mass spectrometry was used to detect the components. Results: PPC normalized serum ALT (40 U/L), down-regulated TLR4-NF-κB signaling pathway to inhibit the release of TNF-α (90 pg/mL), improved the expression of occludin, claudin-4, and ZO-1, and restored the abundance of Muribaculaceae, Bacteroides and Streptococcus. Conclusion: PPC can alleviate ALD by regulating the gut microbiota with an anti-inflammatory and intestinal barrier, and has an application value in developing functional foods.

Overwhelming evidence points to an aberrant Wnt/β-catenin signaling as a critical factor in hepatocellular carcinoma (HCC) and cervical cancer (CC) pathogenesis. Dicerandrol C (DD-9), a dimeric tetrahydroxanthenone isolated from the endophytic fungus Phomopsis asparagi DHS-48 obtained from mangrove plant Rhizophora mangle via chemical epigenetic manipulation of the culture, has demonstrated effective anti-tumor properties, with an obscure action mechanism. The objective of the current study was to explore the efficacy of DD-9 on HepG2 and HeLa cancer cells and its functional mechanism amid the Wnt/β catenin signaling cascade. Isolation of DD-9 was carried out using various column chromatographic methods, and its structure was elucidated with 1D NMR. The cytotoxicity of DD-9 on HepG2 and HeLa cells was observed with respect to the proliferation, clonality, migration, invasion, apoptosis, cell cycle, and Wnt/β-catenin signaling cascade. We found that DD-9 treatment significantly reduced tumor cell proliferation in dose- and time-dependent manners in HepG2 and HeLa cells. The subsequent experiments in vitro implied that DD-63 could significantly suppress the tumor clonality, metastases, and induced apoptosis, and that it arrested the cell cycle at the G0/G1 phase of HepG2 and HeLa cells. Dual luciferase assay, Western blot, and immunofluorescence assay showed that DD-9 could dose-dependently attenuate the Wnt/β-catenin signaling by inhibiting β-catenin transcriptional activity and abrogating β-catenin translocated to the nucleus; down-regulating the transcription level of β-catenin-stimulated Wnt target gene and the expression of related proteins including p-GSK3-β, β-catenin, LEF1, Axin1, c-Myc, and CyclinD1; and up-regulating GSK3-β expression, which indicates that DD-9 stabilized the β-catenin degradation complex, thereby inducing β-catenin degradation and inactivation of the Wnt/β-catenin pathway. The possible interaction between DD-9 and β-catenin and GSK3-β protein was further confirmed by molecular docking studies. Collectively, DD-9 may suppress proliferation and induce apoptosis of liver and cervical cancer cells, possibly at least in part via GSK3-β-mediated crosstalk with the Wnt/β-catenin signaling axis, providing insights into the mechanism for the potency of DD-9 on hepatocellular and cervical cancer.

Abstract Background Little is known about the potential mechanisms of healthy eating and exercise change, and design interventions which aim to promote healthy eating and exercise change among individuals at risk of metabolic syndrome. This study aimed to identify key determinants of healthy eating, exercise behaviors, and health among individuals at risk of metabolic syndrome using the integrated common-sense model of illness self-regulation. Method A cross-sectional study with a multi-wave data collection strategy. A total of 275 participants at risk of metabolic syndrome based on the clinical prediction model were included in the final analysis. Path analysis was employed to explore the pattern of relationships between key variables using AMOS. Results The mediation analysis suggested that personal and treatment control, and coherence can positively affect self-reported health via intentions and health behaviors (exercise and healthy eating). Additionally, relationships between self-efficacy (exercise and healthy eating) and health outcomes can be mediated by health behaviors, and both intentions and health behaviors. Conclusions This current research used the integrated common-sense model of illness self-regulation to predict healthy eating, exercise behaviors, and self-reported health among individuals at risk of metabolic syndrome. The results suggested that self-efficacy, intention, consequences, personal control, treatment control, and coherence were the key determinants of behavior and health, which can help design interventions to encourage healthy eating and exercise changes among individuals with a high risk of MetS.

Background: Data regarding the prognosis of Eisenmenger syndrome (ES) and effect of targeted drugs are limited. This study aimed to analyze the prognosis and impact of targeted drug therapy on the survival rate of patients with ES in the Chinese population. Methods: The data of patients with ES referred to our hospital between January 2010 and December 2020 were retrospectively analyzed. Data included baseline demographics, echocardiographic parameters, and clinical diagnoses. All patients were followed up via telephone interviews in February 2022. The primary endpoint was mortality. Results: Overall, 1,021 patients with ES were included. The 1-, 3-, 5-, 7-, 10-, and 12-year survival rates were 91.6%, 84.2%, 80.7%, 73.8%, 71.4%, and 69.9%, respectively. Patients with atrial septal defects had the best prognosis than those with ventricular septal defects, patent ductus arteriosus, and complex congenital heart disease (CHD) (P

Abstract Browning is a severe problem in the juice industry, which is tremendously affected by quinone (Q) reactivity. Here, the formation rate, electrophilicity, and oxidizing ability of different quinones were investigated. LC/MS was applied to monitor the loss of polyphenols and quinones in model systems during storage. Mathematical modeling of collected LC/MS data was conducted to derive the rate constants of various reactions. Polyphenols containing catechol or pyrogallol groups are more susceptible to oxidation. Periodic acid and quinone mediated oxidation were faster than the autoxidation of polyphenols. Chlorogenic acid (CQA) and 4‐methylcatechol (4MC) only containing B ring can hardly contribute to browning. They must combine with A ring to form yellow polymers. Furthermore, the electrophilicity and oxidizing ability order of quinone is: CQA‐Q ≈ 4MC‐Q > catechin quinone (CAT‐Q) ≈ epicatechin quinone (EC‐Q) > gallic acid quinone (GA‐Q). It was possible that CAT‐Q and EC‐Q would undergo nucleophilic addition with their A rings and GA‐Q's extra hydroxyl group might contribute to the electrons, resulting in lower reactivity. This work innovatively evaluated the reactivity of diverse polyphenols and quinones, attempting to illustrate their contributions to nonenzymatic browning. These findings provide a new perspective to restrain the browning in the juice processing industry.

Abstract Background Germline gain‐of‐function (GOF) variants in the signal transducer and activator of transcription 3 (STAT3) gene lead to a rare inherited disorder characterized by early‐onset multiorgan autoimmunity. Methods We described a Chinese patient with infantile‐onset diabetes and multiorgan autoimmunity. The patient presented with early‐onset type 1 diabetes and autoimmune hypothyroidism at 7 months. During the 7.5‐year follow‐up, she developed pseudo‐celiac enteropathy at 1 year of age and showed severe growth retardation. Whole‐exome sequencing was performed and the novel variant was further assessed by in vitro functional assays. Results Whole‐exome sequencing revealed a novel variant (c.1069G>A, p.Glu357Lys) in the DNA‐binding domain of STAT3. In vitro functional studies revealed that p.Glu357Lys was a GOF variant by increasing STAT3 transcriptional activity and phosphorylation. In addition, the STAT3 Glu357Lys variant caused dysregulation of insulin gene expression by enhancing transcriptional inhibition of the insulin gene enhancer binding protein factor 1 (ISL1). Conclusion In the current study, we describe clinical manifestations and identify a novel STAT3 GOF variant (c.1069G>A) in a Chinese patient. This activating variant impairs insulin expression by increasing transcriptional inhibition of its downstream transcription factor ISL1, which could be involved in the pathogenesis of early‐onset diabetes.

Macrophages play a critical role in innate immunity, with approximately 90% of the total macrophage population in the human body residing in the liver. This population encompasses both resident and infiltrating macrophages. Recent studies highlight the pivotal role of liver macrophages in various aspects such as liver inflammation, regeneration, and immune regulation. A novel pro-inflammatory programmed cell death, pyroptosis, initially identified in macrophages, has garnered substantial attention since its discovery. Studies investigating pyroptosis and inflammation progression have particularly centered around macrophages. In liver diseases, pyroptosis plays an important role in driving the inflammatory response, facilitating the fibrotic process, and promoting tumor progression. Notably, the role of macrophage pyroptosis cannot be understated. This review primarily focuses on the role of macrophage pyroptosis in liver diseases. Additionally, it underscores the therapeutic potential inherent in targeting macrophage pyroptosis.

Equitable and effective planning of urban park green spaces (UPGSs) is an important way to promote green and healthy urban development and improve citizens' quality of life. However, under the background of rapid urbanization, linear large cities, with their unique spatial forms and high-density population agglomerations, have brought special challenges for the planning and management of urban public green spaces. This study takes Lanzhou, a typical representative of high-density linear large cities in China, as a case study. Based on the improvement of the traditional Gaussian Two-Step Floating Catchment Area method (G2SFCA), combined with the Gini coefficient and the Lorentz curve, the social equity and spatial equity of UPGS supply-demand in the central urban area of Lanzhou were evaluated at the city and district scales. Meanwhile, the areas with shortage of UPGS supply-demand were accurately identified as the key areas for future optimization. The results show that: (1) There are significant differences in the equity of UPGS supply-demand in the linear large Lanzhou at the social and spatial levels, and most UPGS resources are enjoyed by a few people; (2) The spatial accessibility of UPGSs has an obvious "string of beads" distribution Characteristics, and the areas with high accessibility are mainly concentrated along rivers; (3) The equity of UPGS supply-demand exhibits a spatial gradient effect, which is characterized by a circle distribution. From the inside to the outside, it is as follows: good supply-dense population, good supply-sparse population, supply shortage-dense population, supply shortage-sparse population. Finally, based on the concept of "progressive micro-regeneration" and the Location Allocation model (LA), the optimal sites for new UPGSs were determined, maximizing the equity of UPGS supply-demand. This provides a practical reference for relevant management departments to optimize park layouts in the future.

BackgroundThe association between body weight perception and intuitive eating among undergraduate students in China remains insufficiently understood. In the present study, we were aimed to examine the correlation between body weight perception, body image, and intuitive eating and determine whether the link between body weight perception and intuitive eating was influenced by body image.MethodsA total of 1,050 undergraduate students completed the survey. Participants provided self-reported demographic details and completed two structured scales. The Body Esteem Scale for Adolescents and Adults (BESAA) and the Intuitive Eating Scale-2 (IES-2) were employed to assess body image and intuitive eating. Analysis of the mediation model was conducted using version 4.1 of the PROCESS Macro. Results with a value of p less than 0.05 were deemed statistically significant.ResultsThe average age of the participants was 20.08 years (SD = 1.64). Among the students, 837 (79.7%) were female, and 212 (20.3%) were male. Body image (r = −0.429, p

Despite women representing most of those affected by major depression, preclinical studies have focused almost exclusively on male subjects, partially due to a lack of ideal animal paradigms. As the persistent need regarding the sex balance of neuroscience research and female-specific pathology of mental disorders surges, the establishment of natural etiology-based and systematically validated animal paradigms for depression with female subjects becomes an urgent scientific problem. This study aims to establish, characterize, and validate a “Multiple Integrated Social Stress (MISS)” model of depression in female C57BL/6J mice by manipulating and integrating daily social stressors that females are experiencing. Female C57BL/6J mice randomly experienced social competition failure in tube test, modified vicarious social defeat stress, unescapable overcrowding stress followed by social isolation on each day, for ten consecutive days. Compared with their controls, female MISS mice exhibited a relatively decreased preference for social interaction and sucrose, along with increased immobility in the tail suspension test, which could last for at least one month. These MISS mice also exhibited increased levels of blood serum corticosterone, interleukin-6 L and 1β. In the pharmacological experiment, MISS-induced dysfunctions in social interaction, sucrose preference, and tail suspension tests were amended by systematically administrating a single dose of sub-anesthetic ketamine, a rapid-onset antidepressant. Compared with controls, MISS females exhibited decreased c-Fos activation in their anterior cingulate cortex, prefrontal cortex, nucleus accumbens and some other depression-related brain regions. Furthermore, 24 h after the last exposure to the paradigm, MISS mice demonstrated a decreased center zone time in the open field test and decreased open arm time in the elevated plus-maze test, indicating anxiety-like behavioral phenotypes. Interestingly, MISS mice developed an excessive nesting ability, suggesting a likely behavioral phenotype of obsessive-compulsive disorder. These data showed that the MISS paradigm was sufficient to generate pathological profiles in female mice to mimic core symptoms, serum biochemistry and neural adaptations of depression in clinical patients. The present study offers a multiple integrated natural etiology-based animal model tool for studying female stress susceptibility.

PurposeTo examine whether body fat rate (BF%) is associated with cardiorespiratory fitness (CRF) and whether cardiorespiratory fitness (CRF) mediates the association between BF% and Executive function (EF) in young adults.MethodsIn this cross-sectional study, 226 college students were recruited from an university. Flanker, 2-back, and odder and shifting tasks were used to assess EF. The incremental cardiopulmonary exercise tests were performed, and maximal oxygen consumption was recorded during test. The body composition measuring instrument was used to evaluate the participants’ BF%.ResultsThe BF% of college students was negatively correlated with each EF, BF% was negatively correlated with CRF, and CRF was negatively correlated with EF (P< 0.001). Structural equation modeling (SEM) and simultaneous analysis of several groups were used to construct mediator model. The CRF of college students plays a partial mediating role between BF% and EF, and the mediating effect accounts for 48.8% of the total effect value. Sex has no moderate effect on the relationship between BF%, CRF, and EF.ConclusionsCollege students with high BF% can improve their CRF by strengthening physical exercise, thereby indirectly improving their EF. Therefore, college students who have a higher body fat percentage should be compensated for engaging in physical exercise in order to enhance their CRF and mitigate the detrimental effects of obesity and overweight on EF.

AbstractBackground Metabolic Syndrome (MetS) is a serious public health issue. Dietary changes form the core of MetS treatment. The adherence to dietary recommendations is critical for reducing the severity of MetS components and preventing complications. However, the adherence to dietary recommendations was not adequate among adults with MetS. This study utilizes the Behaviour Change Wheel (BCW) to develop an individualized WeChat mini program-based behavioural change intervention aimed at strengthening adherence to dietary recommendations in people with MetS.Methods The BCW theory was used to design an individualized WeChat mini program-based behavioural change intervention. A descriptive qualitative study was conducted to identify the determinants of adherence to dietary recommendations in individuals with MetS. The study was conducted at the health promotion centre of a prominent general university hospital in Zhejiang, China. Subsequently, the intervention functions (IFs) and policy categories were selected following the identified determinants. Afterwards, behaviour change techniques (BCTs) were chosen to translate into potential intervention strategies, and the delivery mode was determined.Results Our study identified fifteen barriers to improve the adherence to dietary recommendations in this population. These were linked with six IFs: education, training, persuasion, enablement, modelling, and environmental restructuring. Then, twelve BCTs were linked with the IFs and fifteen barriers. The delivery mode was a WeChat mini program. After these actions, an individualized WeChat mini program-based behavioural change intervention was developed to enhance adherence to dietary recommendations for individuals with MetS.Conclusions The BCW theory helped scientifically and systematically develop an individualized WeChat mini program-based behavioural change intervention for individuals with MetS. In the future, our research team will refine and upgrade the WeChat mini program and then test the usability and effectiveness of the individualized WeChat mini program-based behavioural change intervention program.

AbstractObjective To explore the heterogenous subtypes and the associated factors of health literacy among patients with metabolic syndrome.Methods A cross-sectional study was conducted, and 337 patients with metabolic syndrome were recruited from Sir Run Run Shaw Hospital in Zhejiang Province from December 2021 to February 2022. The Social Support Questionnaire, Short version of the Health Literacy Scale European Questionnaire (HLS-EU-Q16), and MacArthur Scale of Subjective Social Status were used for investigation. Latent class analysis (LCA) was performed to explore the heterogenous subtypes of health literacy among Metabolic syndrome patients. Univariate analysis and logistic regression were used to identify the predictors of the latent classes.Results The findings of LCA suggested that three heterogeneous subtypes of health literacy among individuals with metabolic syndrome were identified: high levels of health literacy, moderate levels of health literacy, and low levels of health literacy. The multinomial logistic regression results indicated that compared with low levels of health literacy class, the high levels of health literacy class were predicted by age (OR 0.932, 95%CI[0.900-0.966]), socio-economic status (OR 1.185, 95%CI[1.058–1.328]), and social support (OR 1.065, 95%CI[1.012–1.120]). Compared with low levels of health literacy class, the moderate levels of health literacy class were predicted by age (OR 0.964, 95%CI[0.934–0.995]), socio-economic status (OR 1.118, 95%CI[1.006–1.242]), male (OR 0.229, 95%CI[0.092–0.576]).Conclusion The levels of health literacy among patients with metabolic syndrome can be divided into three heterogenous subtypes. The results can inform policy-makers and care professionals to design targeted interventions for different subgroups among patients with metabolic syndrome who are male, at older age, have less social support, and with disadvantaged socio-economic status to improve health literacy.

BackgroundResearch on non-target organ damage of biological pesticides has attracted much attention. Rotenone exposure may be far beyond the occupational environment, and the exposureduring pregnancy may be increased through bioaccumulation, fruit or vegetable residues, and other forms of oral intake. At present, the effects of rotenone on placental development and its mechanism are still unknown. ObjectiveTo investigate the developmental damage of rat placenta and evaluate the expression levels of glycogen synthase kinase (GSK-3β) and beta catenin (β-catenin) followed by rotenone exposure through the placental barrier during pregnancy, as well as to propose possible associated mechanisms. MethodsEighteen sexually mature SD female infertile rats without specific pathogens were selected and divided into three groups: blank control group (0.9% saline), corn oil group, and rotenone group (corn oil + 2 mg·kg−1 rotenone) by random number method, six female animals in each group. Another six male rats were selected and mated to the female rats at night with a female to male ratio of 3:1 per cage. Pregnant rats were given 0.9% saline, corn oil, and 2 mg·kg−1 rotenone preparation by isovolumetric gavage once daily for the entire gestation period (19 d), and their conditions were observed after the last dose. The pregnant rats were anesthetized, and the size of the placenta and blood perfusion were detected by ultrasound the next day of the last dose of rotenone. Then, 3 pregnant rats in each group were sacrificed immediately and the placenta and umbilical cord tissues were dissected. The remaining 9 pregnant rats gave birth naturally, and the fetuses were observed for developmental evaluation and weighed. The histopathological changes of umbilical cord and placenta were observed by hematoxylin-eosin staining. The reactive oxygen species levels of placenta tissues were detected by flow cytometry. The Ca2+-ATPase activity of placenta tissues was detected by colorimetric method. The localization and levels of GSK-3β and β-catenin expression of placenta were detected by immunohistochemistry. The p-GSK-3β/GSK-3β and p-β-catenin/β-catenin protein expression in placental tissues were measured by Western blotting. ResultsNo injury or death was recorded during the pregnant rats receiving rotennon administration. Adverse pregnancy outcomes such as fetal absorption and postpartum stillbirth were found in the rotenone group, and the weight of the fetal mice decreased (P

Abstract Background The American Board of Anesthesiology piloted 3-option multiple-choice items (MCIs) for its 2020 administration of 150-item subspecialty in-training examinations for Critical Care Medicine (ITE-CCM) and Pediatric Anesthesiology (ITE-PA). The 3-option MCIs were transformed from their 4-option counterparts, which were administered in 2019, by removing the least effective distractor. The purpose of this study was to compare physician performance, response time, and item and exam characteristics between the 4-option and 3-option exams. Methods Independent-samples t-test was used to examine the differences in physician percent-correct score; paired t-test was used to examine the differences in response time and item characteristics. The Kuder and Richardson Formula 20 was used to calculate the reliability of each exam form. Both the traditional (distractor being selected by fewer than 5% of examinees and/or showing a positive correlation with total score) and sliding scale (adjusting the frequency threshold of distractor being chosen by item difficulty) methods were used to identify non-functioning distractors (NFDs). Results Physicians who took the 3-option ITE-CCM (mean = 67.7%) scored 2.1 percent correct higher than those who took the 4-option ITE-CCM (65.7%). Accordingly, 3-option ITE-CCM items were significantly easier than their 4-option counterparts. No such differences were found between the 4-option and 3-option ITE-PAs (71.8% versus 71.7%). Item discrimination (4-option ITE-CCM [an average of 0.13], 3-option ITE-CCM [0.12]; 4-option ITE-PA [0.08], 3-option ITE-PA [0.09]) and exam reliability (0.75 and 0.74 for 4- and 3-option ITE-CCMs, respectively; 0.62 and 0.67 for 4-option and 3-option ITE-PAs, respectively) were similar between these two formats for both ITEs. On average, physicians spent 3.4 (55.5 versus 58.9) and 1.3 (46.2 versus 47.5) seconds less per item on 3-option items than 4-option items for ITE-CCM and ITE-PA, respectively. Using the traditional method, the percentage of NFDs dropped from 51.3% in the 4-option ITE-CCM to 37.0% in the 3-option ITE-CCM and from 62.7% to 46.0% for the ITE-PA; using the sliding scale method, the percentage of NFDs dropped from 36.0% to 21.7% for the ITE-CCM and from 44.9% to 27.7% for the ITE-PA. Conclusions Three-option MCIs function as robustly as their 4-option counterparts. The efficiency achieved by spending less time on each item poses opportunities to increase content coverage for a fixed testing period. The results should be interpreted in the context of exam content and distribution of examinee abilities.

Background: Graves' disease (GD) among children has attracted wide attention. However, data on long-term follow-up are scarce, especially in China. This study aimed to investigate the prognosis after regular treatments of GD and to identify possible influencing factors. Methods: A total of 204 newly diagnosed GD children in the Children's Hospital of Nanjing Medical University between 2013 and 2019 were included in this study. The cases involved were divided into remission group, relapse group, and continuing treatment group according to therapy outcomes. Relationships between prognosis and possible influencing factors in remission and relapse groups were analyze d. Results: All 204 cases were treated with methimazole at presentation wi th GD. Due to severe complications, 4 (2.0%) cases changed medication to propylthiouracil. Of all the GD children included, 79 (38.7%) had remission, and 40 (50.6%) relapsed after remission. For each additional month before free thyroxine fell into the reference range with treatment, the risk of relapse increased 1.510 times (adjusted odds ratio (OR) = 2.510, 95% CI: 1.561–4.034) compared to those in the remission group. On the contrary, the risk of relapse was reduced by 0.548 times for each additional hour of sleep duration per day (adjusted OR = 0.452, 95% CI: 0.232–0.879). Conclusion: GD children have a high relapse rate after remission, and most of them occur within 1 year. Thyroid function should be reexamined regularly after drug withdrawal. The response to medication and lifestyle of GD children may affe ct the prognosis.

Abstract Background The cholinergic anti-inflammatory pathway (CAP) has been widely studied to modulate the immune response. Current stimulating strategies are invasive or imprecise. Noninvasive low-intensity pulsed ultrasound (LIPUS) has become increasingly appreciated for targeted neuronal modulation. However, its mechanisms and physiological role on myocarditis remain poorly defined. Methods The mouse model of experimental autoimmune myocarditis was established. Low-intensity pulsed ultrasound was targeted at the spleen to stimulate the spleen nerve. Under different ultrasound parameters, histological tests and molecular biology were performed to observe inflammatory lesions and changes in immune cell subsets in the spleen and heart. In addition, we evaluated the dependence of the spleen nerve and cholinergic anti-inflammatory pathway of low-intensity pulsed ultrasound in treating autoimmune myocarditis in mice through different control groups. Results The echocardiography and flow cytometry of splenic or heart infiltrating immune cells revealed that splenic ultrasound could alleviate the immune response, regulate the proportion and function of CD4+ Treg and macrophages by activating cholinergic anti-inflammatory pathway, and finally reduce heart inflammatory injury and improve cardiac remodeling, which is as effective as an acetylcholine receptor agonists GTS-21. Transcriptome sequencing showed significant differential expressed genes due to ultrasound modulation. Conclusions It is worth noting that the ultrasound therapeutic efficacy depends greatly on acoustic pressure and exposure duration, and the effective targeting organ was the spleen but not the heart. This study provides novel insight into the therapeutic potentials of LIPUS, which are essential for its future application. Graphical Abstract

Objective: Sepsis-induced cardiomyopathy is the leading cause of death in sepsis and is characterized by reversible myocardial depression. However, the specific mechanisms responsible for myocardial injury in sepsis are not known. The present study used bioinformatic analysis to explore the possible mechanisms of sepsis-induced myocardial injury and the therapeutic potential of curcumin. Methods: The GSE125042 microarray gene expression matrix was obtained from the Gene Expression Omnibus database, which includes 10 septic cardiomyocyte samples from cecum ligation perforation constructs and 10 sham-operated groups cardiomyocyte samples. Background correction and matrix data normalization were performed using the robust multiarray average algorithm. Differentially expressed genes (DEGs) screening was performed using the Limma R package expression matrix, and whole gene analysis was performed using the weighted gene co-expression network analysis R package to construct gene networks and identify modules. Enrichment analysis and gene set enrichment analysis was performed on the genes to be selected. Construct cellular and animal models of myocardial injury in sepsis were assessed and the effects of curcumin on a rat or cardiac myocytes were observed. Results: A total of 2876 DEGs were screened based on the GSE125042 chip, of which 1424 genes were upregulated and 1452 genes were down regulated. WGCNA analysis of the whole genes was also performed and a total of 20 gene modules were generated. Among them, the selected TLR1 gene was present in the most strongly correlated Brown module. Enrichment analysis of the upregulated DEGs with the Brown module showed that they were significantly enriched in biological processes related to ribosomal protein complex generation, cellular components related to phagocytic vesicles and molecular functions related to Toll-like receptor binding, affecting cardiomyocyte survival as a target for molecular intervention in septic cardiomyopathy. Animal experiments showed that curcumin reduced inflammation levels, improved cardiac function and increased survival in rats with septic myocardial injury. Cellular experiments showed that curcumin increased the survival rate of lipopolysaccharide-treated cardiomyocytes and down regulated TLR1 expression and inhibited NF-κB phosphorylation in cells in a dose-dependent manner. Molecular docking analysis revealed that curcumin interacted with TLR1 by hydrogen bonding and could be stably bound to inhibit the biological function of TLR1. Conclusion: Our study shows that curcumin attenuates myocardial injury in sepsis by inhibiting TLR1 expression, which provides a molecular theoretical basis for clinical treatment. Resumo: Objetivos: A miocardiopatia induzida por sepsis é a principal causa de morte por sepsis e é caracterizada por uma depressão reversível do miocárdio. No entanto, os mecanismos através dos quais a sepsis induz lesão do miocárdio não são conhecidos. O presente estudo utilizou uma análise bioinformática para identificar os possíveis mecanismos de lesão do miocárdio induzida por sepsis e avaliar o potencial terapêutico da curcumina. Métodos: O microarray de expressão génica GSE125042 foi obtida na base de dados Gene Expression Omnibus (GEO), que inclui 10 amostras de cardiomiócitos de animais com sepsis, induzida por perfuração e ligação do ceco (CLP), e 10 amostras de cardiomiócitos de animais controlo (Sham). A correção e a normalização dos dados da matriz foram realizadas recorrendo ao algoritmo robusto de média multiarray (RMA). A identificação dos genes diferencialmente expressos (DEGs) foi realizada usando a matriz de expressão Limma R e a análise de genes inteiros foi realizada através da análise ponderada de rede de coexpressão de genes (WGCNA) R para construir redes de genes e identificar módulos. A análise de enriquecimento e a análise de enriquecimento do conjunto genético (GSEA) foram realizadas nos genes a selecionar. Foi avaliado o efeito da curcumina na lesão miocárdica, em modelos celulares e animais de lesão sepsis. Resultados: Foram avaliados 2876 DEGs com base no chip GSE125042, dos quais 1424 genes estavam sobrerregulados e 1452 genes estavam subregulados. Foi também realizada uma análise WGCNA de todos os genes e foram gerados 20 módulos de genes. Entre eles, o gene selecionado TLR1 estava presente no módulo de Brown mais fortemente correlacionado. A análise de enrriquecimento dos DEGs sobrerregulados com o módulo Brown mostrou que estes foram significativamente enriquecidos em processos biológicos relacionados com a geração do complexo proteico ribossómico (BP), componentes celulares relacionados com vesículas fagocitárias (CC) e funções moleculares relacionadas os Toll-like receptors (MF), que podem constituir alvos moleculares envolvidos na sobrevivência dos cardiomiócitos na cardiomiopatia séptica. Experiências com animais mostraram que a curcumina reduziu os níveis de inflamação, melhorou a função cardíaca e aumentou a sobrevivência em ratos com lesão séptica do miocárdio. Experiências celulares mostraram que a curcumina aumentou a taxa de sobrevivência de cardiomiócitos tratados com LPS e a expressão de TLR1 desregulada e inibiu a fosforilação NF-κB nas células, de uma forma dependente da dose. A análise da acoplagem molecular revelou que a curcumina interagia com TLR1 através de ligação de hidrogénio, o que poderia inibir a função biológica de TLR1. Conclusão: O nosso estudo demonstrou que a curcumina atenua a lesão do miocárdio por sepsis ao inibir a expressão do TLR1, constituindo uma base teórica molecular para novas abordagens terapêuticas.

Recent studies increasingly suggest that targeting brown/beige adipose tissues to enhance energy expenditure offers a novel therapeutic approach for treating metabolic diseases. Brown/beige adipocytes exhibit elevated expression of uncoupling protein 1 (UCP1), which is a thermogenic protein that efficiently converts energy into heat, particularly in response to cold stimulation. Polyphenols possess potential anti-obesity properties, but their pharmacological effects are limited by their bioavailability and distribution within tissue. This study discovered 18a, a polyphenol compound with a favorable distribution within adipose tissues, which transcriptionally activates UCP1, thereby promoting thermogenesis and enhancing mitochondrial respiration in brown adipocytes. Furthermore, in vivo studies demonstrated that 18a prevents high-fat-diet-induced weight gain and improves insulin sensitivity. Our research provides strong mechanistic evidence that UCP1 is a complex mediator of 18a-induced thermogenesis, which is a critical process in obesity mitigation. Brown adipose thermogenesis is triggered by 18a via the AMPK-PGC-1α pathway. As a result, our research highlights a thermogenic controlled polyphenol compound 18a and clarifies its underlying mechanisms, thus offering a potential strategy for the thermogenic targeting of adipose tissue to reduce the incidence of obesity and its related metabolic problems.

Phase change material (PCM) based thermal energy storage (TES) is an important solution to the waste of heat and intermittency of new energy sources. However, the thermal conductivity of most PCMs is low, which severely affects the thermal energy storage performance. Oscillation of the tube bundles in a TES unit can intensify the convection of liquid PCM and, therefore, enhance heat transfer. However, the energy storage performance of bundled-tube TES systems in response to oscillation at different amplitudes and frequencies has not been well understood yet, and the optimum time to apply the oscillation during phase transition remains unexplored. To address this issue, this present study was carried out. First, the melting behaviour of PCM with oscillation starting at different times was investigated. Then, the influences of oscillation frequency and amplitude on the melting performance were explored. Finally, the solidification behaviour of PCM with oscillation starting at different times was examined. Results show that the oscillation can accelerate the phase transition process by enhancing convective heat transfer. Compared to the case without oscillation, the complete melting and solidification times are reduced by 8.2 and 6.7% for the case with oscillation starting at 200 s, respectively. The effect of oscillation frequency on the melting enhancement is negligible, while the oscillation amplitude has an important effect on the melting enhancement.

BackgroundMetabolic syndrome (MetS) is a common public health challenge. Health-promoting behaviors such as diet and physical activity are central to preventing and controlling MetS. However, the adoption of diet and physical activity behaviors has always been challenging. An individualized mobile health (mHealth)–based intervention using the Behavior Change Wheel is promising in promoting health behavior change and reducing atherosclerotic cardiovascular disease (ASCVD) risk. However, the effects of this intervention are not well understood among people with MetS in mainland China. ObjectiveWe aimed to evaluate the effects of the individualized mHealth-based intervention using the Behavior Change Wheel on behavior change and ASCVD risk in people with MetS. MethodsWe conducted a quasi-experimental, nonrandomized study. Individuals with MetS were recruited from the health promotion center of a tertiary hospital in Zhejiang province, China. The study involved 138 adults with MetS, comprising a control group of 69 participants and an intervention group of 69 participants. All participants received health education regarding diet and physical activity. The intervention group additionally received a 12-week individualized intervention through a WeChat mini program and a telephone follow-up in the sixth week of the intervention. Primary outcomes included diet, physical activity behaviors, and ASCVD risk. Secondary outcomes included diet self-efficacy, physical activity self-efficacy, knowledge of MetS, quality of life, and the quality and efficiency of health management services. The Mann-Whitney U test and Wilcoxon signed rank test were primarily used for data analysis. Data analysis was conducted based on the intention-to-treat principle using SPSS (version 25.0; IBM Corp). ResultsBaseline characteristics did not differ between the 2 groups.

Water stress is an important factor affecting herb quality and yield and exogenous spermidine (Spd) addition can enhance dehydration tolerance of plants. Anoectochilus roxburghii (Wall.) Lindl is a perennial herb widely used in medicine, health care, and beauty industry, yet, its dehydration resistance remains largely unknown. In this view, the current research aimed at elucidating the drought resistance mechanism of A. roxburghii under PEG-induced water stress at different levels (10%, 20%, and 30% PEG6000). In particular, the morphological, physiological, and biochemical changes occurring in leaves treated with (0.5 mM, 5 mM) or without Spd were discussed under moderate water stress (20% PEG6000). Results showed that water stress significantly inhibited the growth of A. roxburghii by decreasing the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), arginine decarboxylase (ADC), S-adenosylmethionine decarboxylase (SAMDC), and polyamine oxidase (PAO). The contents of soluble protein, soluble proline, hydrogen peroxide (H2O2), malondialdehyde (MDA), and the relative conductivity (REC) of leaves increased by 27.32%, 31.37%, 68.84%, 103.61%, and 63.64%, respectively. Under dehydration condition, foliar spraying Spd effectively improved plant growth with the contents of soluble protein and soluble proline increased, while the H2O2, REC, and MDA contents decreased. The SOD activity of 0.5 mM and 5 mM treatments were 1.13 and 1.01 times higher than only 20% PEG treatment, respectively. Similarly, the POD activity of 0.5 mM and 5 mM treatments increased by 52.82% and 34.11%, while the CAT activity of 0.5 mM and 5 mM treatments increased by 34.39 and 33.15 U/mgprot, respectively. In addition, exogenous Spd application significantly increased the key enzyme activities of polyamine metabolism (ADC, SAMDC, and PAO) under moderate water stress. In conclusion, exogenous Spd addition with low concentration (0.5 mM) improved the resistance of A. roxburghii against water stress by increasing the antioxidant enzymes activities and endogenous polyamines contents. This study helps to the understanding of dehydration resistance of A. roxburghii and provide guidelines for its cultivation under water deficit condition.

BackgroundExercise has the potential to reduce symptoms for breast cancer patients during adjuvant treatment, and high-quality systematic reviews are essential for guiding clinical practice. The objective of this umbrella review is to examine current research evidence concerning the effectiveness of exercise on symptom management in breast cancer patients undergoing adjuvant treatment.MethodsAn umbrella review was conducted. We searched for eligible systematic reviews through 11 databases until August 13rd, 2023. Two authors independently screened titles and abstracts, assessing the full-text studies based on inclusion criteria. We used AMSTAR-2 to appraise the quality of the meta-analyses. The results would be presented with narrative summaries if the replication rate of the original study for a symptom was higher than 5% (calculated via the Corrected Covered Area, CCA). The protocol was documented in the PROSPERO registry (CRD42023403990).ResultsOf the 807 systematic reviews identified, 15 met the inclusion criteria, and 7 symptoms were the main focus. The main form of exercise mentioned was aerobic combined resistance exercise. The results of the quality assessment were mostly critically low (10/15). The repetition rate calculated by CCA showed moderate to very high repetition rates (10% to 18.6%). The findings of the included reviews indicated that the effects of exercise on relieving symptoms during breast cancer adjuvant treatment were mixed.ConclusionsResearch is still needed to confirm the majority of studies’ recommendations for exercise during adjuvant treatment for breast cancer patients, as it is crucial for managing symptoms in the rehabilitation process. To increase the efficiency of exercise in symptom management, future studies may focus more on the application of bridge symptoms, symptom networks, and ecological instantaneous assessment.

Metamaterial absorbers (MA) in terahertz (THz) based bands are receiving much attention for its potential applications. However, the limited bandwidth greatly reduces the further development and wide application of terahertz absorbers. To solve this problem, achieving ultra-broadband and efficient absorption characteristics in the terahertz band, we propose a nickel-based microstructure ultra-broadband MA that operates in the THz band. The proposed MA's electromagnetic wave absorption characteristics and physical absorption mechanism are modeled and numerically simulated. The research demonstrates that MA can achieve ultra-wideband efficient absorption covering the whole THz spectrum (0.1 THz-16 THz) with an overall absorption rate of over 95%. The proposed absorber has polarization-insensitive characteristics and achieves a broad-angle incidence with a range of almost 80°.allows a range of incidence angles up to 80°. The MA consists of only three classical metal-dielectric layer-metal structures, which greatly reduces the application cost. The proposed ultra-thin geometry super-surface scheme uses a flexible absorbing material (ECCOSORB AN-72), and the results show that the overall absorption efficiency are significantly improved after the application of the flexible absorbing material. This design presents a unique and innovative idea for the development and use of ultrawideband terahertz absorbers across various industries including terahertz stealth, sensor technology, imaging, and communication, as well as optoelectronics. The potential applications of this technology are vast and can greatly benefit these industries.

Hydrogen energy has long been recognized as a clean alternative to conventional fossil fuels, which can be applied in a wide range of transportation and power generation applications. The rational design and engineering of high-performance and robust catalysts for hydrogen evolution reaction (HER) shows not a great significance but a challenge for efficient electrochemical water splitting. Herein, a new type of Ni-based Ni-ABDC precursor has been obtained, which leads to the formation of N-doped porous carbon nanomaterials uniformly coated with well-proportioned bimetallic AgNi alloys via a stepwise strategy. To their credit, all samples of AgNi/NC-X are structurally calcined from the pristine AgNi-ABDC-X by tuning the different concentration of AgNO3, which means all of them maintain the vermicelli-like morphology compared with Ni-ABDC. The series of AgNi/NC-X materials can be regarded as effective electrocatalysts for HER both in acidic and alkaline media, but an acid-leaching phenomenon is observed. Among them, the as-prepared AgNi/NC-2 exhibits a low overpotential of 103 mV at the current density of 10 mA cm−2 and decent durability with a high retention rate of 90.9% after 10 h in 1.0 mol L−1 KOH electrolyte. The compelling HER properties of AgNi/NC-2 can be attributed to the synergistic effect between the hierarchical carbon materials, partial N-doping and abundant AgNi alloys. Meanwhile, this study provides a practicable method for the development of efficient HER electrocatalysts for energy applications, which can be conveniently prepared through the reasonable introduction of active components in the crystalline inorganic-organic precursors.

Abstract Polygonum chinense Linn. (Polygonum chinense L.) is one of the main raw materials of Chinese patent medicines such as Guangdong herbal tea. The increasing antibiotic resistance of S. aureus and the biofilm poses a serious health threat to humans, and there is an urgent need to provide new antimicrobial agents. As a traditional Chinese medicine, the antibacterial effect of Polygonum chinense L. has been reported, but the antibacterial mechanism of Polygonum chinense L.aqueous extract and its effect on biofilm have not been studied in great detail, which hinders its application as an effective antibacterial agent. In this study, the mechanism of action of Polygonum chinense L.aqueous extract on Staphylococcus aureus (S. aureus) and its biofilm was mainly evaluated by morphological observation, flow cytometry and laser confocal experiments. Our findings demonstrate that Polygonum chinense L.aqueous extract has a significant bacteriostatic effect on S. aureus. The result of growth curve exhibits that Polygonum chinense L.aqueous extract presents a significant inhibitory effect against S. aureus. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) reveals that Polygonum chinense L.aqueous extract exerts a potent destruction of the cell wall of S. aureus and a significant inhibitory effect on the formation of S. aureus biofilm. In addition, flow cytometry showed the ability of Polygonum chinense L.aqueous extract to promote apoptosis by disrupting cell membranes of S. aureus. Notably, confocal laser scanning microscopy (CLSM) images illustrated the ability of Polygonum chinense L.aqueous to inhibit the formation of S. aureus biofilms in a dose-dependent manner. These results suggested that Polygonum chinense L.aqueous is a promising alternative antibacterial and anti-biofilm agent for combating infections caused by planktonic and biofilm cells of S. aureus.
