Objective: To examine the association between school sports environment and exercise habits among college students, and to test the mediating role of weight management intention in the relationship, so as to provide empirical evidence for promoting exercise habit formation of college students. Methods: A multi stage cluster sampling survey was conducted from April 15 to May 15, 2025, among 2 687 undergraduates from 8 colleges in Beijing, Shandong, Henan, Shanxi and Guangxi Zhuang Autonomous Region in China. School Sports Environment Characteristics Questionnaire, Weight Management Behavioral Intention Questionnaire and College Students Exercise Habit Scale were used for evaluation. Pearson correlation analysis was applied to examine the correlations among the three variables. A structural equation model (SEM) was constructed using AMOS 26.0, and the mediating effect was tested using the Bootstrap method. Results: The score for school sports environment was (3.72±0.57), with scores of (3.68±0.61) for physical environment and (3.74±0.59) for social environment; the scores for weight management intention and the total exercise habit were (4.21±0.46) and (3.94±0.51). School sports environment was positively correlated with weight management intention ( r =0.56) and exercise habits ( r =0.57), and weight management intention was positively correlated with exercise habits ( r =0.71) (all P <0.01). The SEM showed that school sports environment exerted positive impact on weight management intention ( β =0.50) and exercise habits ( β =0.29), weight management intention had a significant positive path to exercise habits ( β =0.52) (all P <0.01). Weight management intention of college students played a partial mediating role in the association between school sports environment and exercise habits, with an indirect effect of 0.259, accounting for 47.01% of the total effect. Conclusions The school sports environment is positively correlated with college students exercise habits, and might indirectly facilitate habit cultivation by improving weight management intention. While optimizing the physical and social environments of school sports in colleges, colleges should place a strong emphasis on stimulating college students weight management intention to promote the formation of their exercise habits.

Objective:To investigate the role of inhibitor of differentiation 2(Id2)in inducing the generation of central memory T(Tcm)cells and enhancing the anti-tumor persistence of T cells.Methods:CD8+na?ve T cells were sorted with magnetic beads and then co-cultured with carcinoembryonic antigen(CEA)-loaded dendritic cells(DCs).These cells were induced into effector T(Teff)or Tcm cells by interleukin-2(IL-2)or IL-7/15/21/23,respectively.The mRNA and protein expression of Id2 and Id3 in T cells were detected using qPCR and WB,respectively.Id2 gene in T cells was knocked down using lentivirus,and the T cell memory phenotype was analyzed by flow cytometry.The expression of PI3K/AKT pathway-related proteins was examined by WB.The extracellular acidification rate(ECAR)and oxygen consumption rate(OCR)were assessed using a Seahorse extracellular flux analyzer.A zebrafish colorectal cancer HCT116 xenograft model was employed to analyze the anti-tumor differences between Teff and Tcm cells.The effect of Id2 gene knockdown in Tcm cells(Tcm-shId2)on the growth inhibition of secondary xenografts was also observed.Results:Tcm cells exhibited high expression of Id3 mRNA(P<0.05),whereas Teff cells showed high expression of Id2 mRNA(P<0.001).Tcm cells with Id2 knockdown(Tcm-shId2)were successfully constructed,showing significantly upregulated Id3 expression.Knockdown of Id2 promoted the formation of Tcm cell(P<0.05).Tcm-shId2 cells underwent metabolic reprogramming via the PI3K/AKT pathway,which effectively suppressed the growth of colorectal cancer xenografts in zebrafish and also produced significant inhibitory effects on secondary tumor growth(P<0.01).Conclusion:Id2 gene may regulate T cell metabolism through the PI3K/AKT signaling pathway,promoting the differentiation of CD8+T cells into Tcm cells and effectively inhibiting the growth of colorectal cancer xenografts.

The experts reached a consensus on the comprehensiveness and practicability of the index system, aiming to lay a solid foundation for construction of China's schistosomiasis prevention and control early warning system.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objectives:To quantitatively evaluate the relationship between triglyceride-glucose index and stroke risk by a dose-response meta-analysis.Methods:Prospective cohort studies on the association between triglyceride-glucose(TyG)index and stroke risk were searched by computer in China National Knowledge Infrastructure(CNKI),Wanfang Data Knowledge Service Platform,VIP,China Biomedical Literature Database,PubMed,Embase and Web of Science.The retrieval time was from the self-established database to November 7,2024.Two researchers used the Newcastle-Ottawa Scale(NOS)to evaluate literature quality and then extract relevant data for the included literatures.Stata 17.0 software was used for statistical analysis.Results:A total of 17 prospective literatures were included,involving 449 210 subjects,including 28 506 patients with stroke.The results of meta-analysis showed that the TyG index was positively correlated with the risk of stroke(HR=1.60,95%CI:1.45-1.76,P<0.05).The results of dose-response meta-analysis showed that there was a positive correlation between the TyG index and the risk of stroke,and every 1 unit increase of the TyG index,the risk of stroke increased by 20.2%.According to Egger's test,the P value is 0.962,and the P value of Begg's test is 0.967,indicating that there was no publication bias in the literature included in this study.Conclusions:There is a linear dose-response relationship between TyG index and stroke risk,and higher TyG index can increase the risk of stroke.
