Objective To investigate the status and influencing factors of overweight and obesity among primary and secondary school students in Pudong New Area of Shanghai, and to provide reference for formulating obesity-related intervention strategies for school-age children. Methods Stratified cluster random sampling method was used to conduct a questionnaire survey among primary and secondary school students in Pudong New Area. The overweight and obesity rate was calculated according to the Chinese health industry standard, and the risk factors of overweight and obesity in children and adolescents of different school age groups were analyzed by logistic regression. Results The overweight and obesity rate (25.3%) of primary and secondary school students in Pudong New Area exceeded the national average level. In primary school group, male, sleep time ≥ 8h per day, water intake ≥ 1200 mL per day, and the presence of mobile food stalls around the school were the risk factors for overweight and obesity. Daily extracurricular exercise time of 30 minutes to 2 hours was a protective factor. In junior high school group, male and electronic product use time of ≥ 2h per day were the risk factors for overweight and obesity. The daily extracurricular exercise time of 1 to 2 hours was a protective factor. In high school group, drinking water ≥1200mL per day was a risk factor for overweight and obesity. Eating breakfast every day for the past week was a protective factor. Conclusion Group intervention targeting overweight and obese school-age children, while changing corresponding unhealthy habits according to different school age groups, is crucial for weight loss in school-age children.

Pristimerin, which is one of the compounds present in Celastraceae and Hippocrateaceae, has antitumor effects. However, its mechanism of action in esophageal squamous cell carcinoma (ESCC) remains unclear. This study aims to investigate the efficacy and mechanism of pristimerin on ESCC in vitro and in vivo. The inhibitory effect of pristimerin on cell growth was assessed using trypan blue exclusion and colony formation assays. Cell apoptosis was evaluated by flow cytometry. Gene and protein expressions were analyzed through quantitative reverse transcription-polymerase chain reaction (qRT-PCR), Western blotting, and immunohistochemistry. RNA sequencing (RNA-Seq) was employed to identify significantly differentially expressed genes (DEGs). Cell transfection and RNA interference assays were utilized to examine the role of key proteins in pristimerin?s effect. Xenograft models were established to evaluate the antitumor efficiency of pristimerin in vivo. Pristimerin inhibited cell growth and induced apoptosis in ESCC cells. Upregulation of Noxa was crucial for pristimerin-induced apoptosis. Pristimerin activated the Forkhead box O3a (FoxO3a) signaling pathway and triggered FoxO3a recruitment to the Noxa promoter, leading to Noxa transcription. Blocking FoxO3a reversed pristimerin-induced Noxa upregulation and cell apoptosis. Pristimerin treatment suppressed xenograft tumors in nude mice, but these effects were largely negated in Noxa-KO tumors. Furthermore, the chemosensitization effects of pristimerin in vitro and in vivo were mediated by Noxa. This study demonstrates that pristimerin exerts an antitumor effect on ESCC by inducing AKT/FoxO3a-mediated Noxa upregulation. These findings suggest that pristimerin may serve as a potent anticancer agent for ESCC treatment.

Objective:
To investigate the association between edentulism and the risk of social isolation in middle-aged and elderly populations, provide empirical evidence for formulating social isolation prevention and intervention policies targeting edentulous middle-aged and elderly populations.
Methods:
Data were derived from the baseline survey (2011) and three follow-ups (2013, 2015, 2018) of the China Health and Retirement Longitudinal Study (CHARLS). Participants were enrolled in the follow-up from the baseline. Those identified as socially isolated in any of the follow-up surveys conducted in 2013, 2015, or 2018 were considered to have reached the endpoint; otherwise, the follow-up was continued until the end of the 2018 survey; 9 870 individuals were ultimately included. Subjects were grouped by edentulism status. Chi-square test and multivariate Cox regression analysis were performed using Stata 17.0.
Results:
During a median follow-up of 6.54 years, 1 800 cases of social isolation occurred, with an incidence rate of 18.23%(17.47%~18.99%). Multivariate Cox regression showed that edentulism was associated with an increased risk of social isolation (HR=1.21, 95% CI: 1.03-1.42) after adjusting for confounders. Subgroup analysis revealed population heterogeneity. Sensitivity analyses confirmed the stability of the results.
Conclusion
Edentulism is associated with an increased risk of social isolation in middle-aged and elderly adults.

There are certain limitations in the current clinical evaluation methods and evaluation modes of new Chinese herbal medicines for syndromes, and there is a lack of a clinical evaluation system that meets the characteristics of traditional Chinese medicine (TCM). Based on the characteristics of TCM "syndrome differentiation and treatment" and "correspondence of formulas and syndromes", the target design model, hypothesis and its scope of application are proposed on the basis of the combination of diseases and syndromes. On the basis of fully considering the dual factors of diseases and syndromes, we distinguished the "centre of the target", "middle ring" and "outer ring" through the differences of different signs and symptoms in people with same syndrome, in order to determine the degree of conformity of the syndrome. Then, the population with same syndrome could be analysed according to the "centre of the target", "middle ring" and "outer ring", so as to achieve the precise positioning of new Chinese herbal medicines for syndromes, and try to provide research ideas and methods for syndrome differentiation and treatment of TCM and precise intervention.

【Objective】 To investigate the therapeutic effect of Huaier on acute pancreatitis (AP) and its potential mechanism. 【Methods】 A mouse model of cerulean-induced AP was used to verify the therapeutic effect of Huaier in vivo. HE staining and immunohistochemical staining were used to evaluate the histopathological changes of the pancreas, and transmission electron microscopy was used to observe the pyroptosis morphology of the pancreas. In vitro, 266-6 cell line was used as the experimental carrier to verify the protective effect of Huaier on acinar cells. Electron microscopy and Western blotting were used to evaluate the pyroptosis level of acinar cells, and ROS fluorescence probe was used to detect the oxidative stress state of acinar cells. 【Results】 Huaier significantly alleviated the severity of AP in mice. HE staining of pancreas showed that necrosis and inflammatory cell infiltration were reduced, and the level of serum amylase was decreased. Immunohistochemical staining and Western blotting showed that Huaier effectively inhibited the expressions of pyroptosis-related molecules such as NLRP3 and GSDMD in pancreatic tissue. Electron microscopy showed that Huaier could reduce the pyroptosis level of pancreatic acinar cells under inflammatory state. In addition, the level of ROS in acinar cells was significantly reduced after the intervention of Huaier, and ROS-mediated pyroptosis of acinar cells could be effectively inhibited by Huaier. 【Conclusion】 Huaier can effectively reduce the severity of AP by inhibiting ROS-mediated pyroptosis of acinar cells.
