Objective: To analyze the text structure, temporal evolution, and mechanism related shortcomings of policies related to family-school-society collaboration in promoting students physical and mental health in China, thereby providing a reference for improving collaborative mechanisms in the context of health promoting school development. Methods: The PKULAW Laws and Regulations Database was used as the data source. A total of 115 relevant policy documents issued by relevant departments from the founding of the People s Republic of China to May 7, 2026, were included. Drawing on the adolescent health policy analysis framework and adapting it to the Chinese contexts of family-school-society collaborative education, health promoting school development, and interdepartmental collaborative governance, policy text analysis was conducted. Multi label coding was applied to 629 semantic units, and fractional counting was used to calculate the weights of 6 main dimensions and 31 subdimensions and to describe the dimensional composition of the policies and its changes over time. Results: Policies related to family-school-society collaboration in promoting students physical and mental health gradually evolved from early principle based collaboration centered on the ideological and moral development of minors into institutional arrangements supported by the Healthy China initiative, the legal institutionalization of family education, collaborative education mechanisms, and health promoting school development. Among the 6 main dimensions, policy features and costs accounted for 54.8% of the total weight, followed by implementation considerations (22.9%), monitoring and evaluation (9.5%), policy appropriateness (5.6%), inclusion and coverage (4.8%), and participatory approach (2.5%). At the subdimension level, proposed interventions, target population characteristics, intersectoral linkages, consideration of adolescents social ecology, and goal setting accounted for 18.7%, 16.0%, 12.0%, 9.6%, and 9.4% of the total weight, respectively, whereas adolescent participation and the incorporation of young people s voices accounted for only 0.3% and 0.1% , respectively. These findings indicated that the policy texts focused primarily on problem identification, target population specification, and implementation arrangements, while provisions concerning students active participation, identification of differentiated needs, and support from disaggregated data remained relatively limited. Conclusions China has established a policy framework for family-school-society collaboration in promoting students physical and mental health that emphasizes goal setting, responsibility division, and organizational implementation, while gradually extending to specific health promotion tasks. Nevertheless, policy provisions concerning students active participation, the identification of differentiated needs, stratified and category specific monitoring, and the use of evaluation feedback require further specification.

BACKGROUND:The regulation of intestinal flora by exercise is closely related to human health,but intestinal flora involves many factors.Existing studies have lacked consistent evidence on the effect of exercise on the intestinal flora of college students. OBJECTIVE:To explore the effects of exercise on intestinal flora diversity and species composition of college students. METHODS:Through systematic search of PubMed,Web of Science,Embase,Medline,Cochrane Library,CNKI,WanFang Database and VIP database,eight empirical studies were selected and included,and semi-quantitative analysis was performed on them. RESULTS AND CONCLUSION:In terms of the species diversity of the intestinal flora,both high-intensity interval training and Tai Chi exercise significantly enhance the species diversity of intestinal flora in college students,while aerobic exercise does not have a significant effect on the enhancement of intestinal flora diversity in college students.In terms of the species composition of the intestinal flora,all three exercise modalities significantly alter the compositional structure of the intestinal flora in college students,which can increase the abundance of beneficial bacteria such as Ruminalococcus,Faecalis prevotelli,Blautia,and decrease the abundance of harmful bacteria such as Escherichia spp.Compared with high-intensity interval training,aerobic and Tai Chi exercise causes more elevated abundance of beneficial bacteria.In addition to changes in intestinal flora characteristics,exercise improves body composition,cardiorespiratory function,and executive function in college students,and these health benefits are closely linked to exercise-induced changes in intestinal flora that can produce health benefits for the body through metabolic regulation,barrier function,and neuromodulation.Although studies have confirmed the association between exercise and intestinal flora,the mechanism by which exercise affects intestinal flora has not yet been clarified,and at the same time,localizing the flora related to the host health is the key to targeting intestinal flora as a therapeutic target in the future,all of which are worthy of further attention and investigation.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective: To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion. Methods: Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents. Results: In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14)，and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05). Conclusions The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

BACKGROUND: The urban-rural disparities in overweight and obesity among children and adolescents are narrowing, and there is a need for long-term and updated data to explain this inequality, understand the underlying mechanisms, and identify priority groups for interventions. METHODS: We analyzed data from seven rounds of the Chinese National Survey on Students Constitution and Health (CNSSCH) conducted from 1985 to 2019, focusing on school-age children and adolescents aged 7-18 years. Joinpoint regression was used to identify inflection points (indicating a change in the trend) in the prevalence of overweight and obesity during the study period, stratified by urban/rural areas and sex. Annual percent change (APC), average annual percent change (AAPC), and 95% confidence interval (CI) were used to describe changes in the prevalence of overweight and obesity. Polynomial regression models were used to predict the prevalence of overweight and obesity among children and adolescents in 2025 and 2030, considering urban/rural areas, sex, and age groups. RESULTS: The prevalence of overweight and obesity in urban boys and girls showed an inflection point of 2000, with AAPC values of 10.09% (95% CI: 7.33-12.92%, t = 7.414, P <0.001) and 8.67% (95% CI: 6.10-11.30%, t = 6.809, P <0.001), respectively. The APC for urban boys decreased from 18.31% (95% CI: 4.72-33.67%, t = 5.926, P = 0.027) to 4.01% (95% CI: 1.33-6.75%, t = 6.486, P = 0.023), while the APC for urban girls decreased from 13.88% (95% CI: 1.82-27.38%, t = 4.994, P = 0.038) to 4.72% (95% CI: 1.43-8.12%, t = 6.215, P = 0.025). However, no inflection points were observed in the best-fit models for rural boys and girls during the period 1985-2019. The prevalence of overweight and obesity for both urban and rural boys is expected to converge at 35.76% by approximately 2027. A similar pattern is observed for urban and rural girls, with a prevalence of overweight and obesity reaching 20.86% in 2025. CONCLUSIONS The prevalence of overweight and obesity among Chinese children and adolescents has been steadily increasing from 1985 to 2019. A complete reversal in urban-rural prevalence is expected by 2027, with a higher prevalence of overweight and obesity in rural areas. Urgent action is needed to address health inequities and increase investments, particularly policies targeting rural children and adolescents.

BACKGROUND: Urolithiasis is a widespread disease with a high prevalence worldwide. This study aims to evaluate the disease burden of urolithiasis and its trends from 1990 to 2021 globally, based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 database. METHODS: The numbers and age-standardized rates (ASRs) of incidence, disability-adjusted life years (DALYs), and mortality of urolithiasis were extracted from GBD 2021 to represent the disease burden. Joinpoint regression analyses were conducted to assess the temporal trends in the burden of urolithiasis. The male-to-female ASR ratio indices were used to evaluate sex disparities. Additionally, we explored the relationship between the ASR ratio and the sociodemographic index (SDI). RESULTS: The total numbers of incidence, DALY, and mortality of urolithiasis were 105,983,780 cases (95% uncertainty interval [UI] = 88,349,356-128,645,155 cases), 693,444 cases (95% UI = 567,765-850,490 cases), and 17,672 cases (95% UI = 13,932-21,241 cases), respectively, in 2021. There is an increasing trend in the number of these measures globally, whereas the ASRs have decreased over the past 30 years. The age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) were significantly higher in males than in females in 2021. The sex disparities in the age-standardized DALY rate (ASDR) and ASMR of urolithiasis were negatively correlated with the SDI. In 2021, the ASIR of urolithiasis was 964.70 (95% UI = 801.26-1175.09) per 100,000 people in China, which is much lower than the global average (1242.84 [95% UI = 1034.94-1506.99] per 100,000 people). Compared with the global average, a more pronounced decline in ASIR was observed in China from 1793.16 (1446.0-2235.14) in 1990 to 964.70 (801.26-1175.09) per 100,000 people in 2021. CONCLUSIONS Urolithiasis poses a significant healthcare burden worldwide. More robust global and national strategies are warranted to address the prevention and treatment, especially in low SDI countries and regions.

The connection between tendons and bones is called the tendon bone connection. With the continuous improvement of national sports awareness, excessive exercises and the related intensity are prone to damage the tendon bone connection. Tendon bone healing is a complex repair and healing process involving multiple factors, and good tendon bone healing is a prerequisite for its physiological function. The complexity of tendon bone structure also poses great challenges to the repair of tendon bone injuries. In recent years, researches have found that stem cells, growth factors, macrophages, and other factors are closely related to the healing process of tendon bone injuries, among which macrophages play an important role in the healing process. The authors reviewed relevant research literature in recent years and summarized the role of macrophages in tendon bone healing, in order to provide new ideas and directions for treatment strategies to promote tendon bone healing.

Objective To analyze the clinical and immunological characteristics of a rare case of CHARGE syndrome,we summarize the genotype and phenotype in the Chinese patient population,and explore the underlying immunopathogenic mechanisms.Methods Clinical data from a pediatric patient with CHARGE syndrome were collected and analyzed.A comprehensive analysis of the Chinese patient population was conducted.Gene analysis and immunological characterization were performed using flow cytometry,deep sequencing,and quantitative PCR.Results The proband was a premature female infant whose primary clinical manifestations included congenital heart disease,recurrent respiratory infections,respiratory failure,airway dysplasia,hearing impairment,and bilateral choroidal coloboma.Whole-exome sequencing revealed a de novo heterozygous nonsense mutation in the CHD7 gene,c.5122C＞T(p.Gln1708Ter),classified as pathogenic according to ACMG criteria.Immunological studies indicated impaired thymic output of T cells,significant alterations in the number and proportion of CD8+T cell subsets,increased apoptosis,and defective activation and production of key effector cytokines such as IFN-γ by CD8+T cells.However,no significant abnormalities were observed in peripheral lymphocyte proliferation.Conclusion CHARGE syndrome is a rare autosomal dominant genetic disorder primarily caused by mutations in the CHD7 gene.The main clinical features include ocular defects,cardiac disease,choanal atresia/cleft lip and palate,growth retardation,gonadal hypoplasia,and ear anomalies.This case study suggests that CHARGE syndrome is associated with abnormalities in the development,apoptosis,and effector functions of immune cells.

Pancreatic cancer is highly aggressive and often diagnosed at an advanced stage,leaving most patients ineligible for radical resection.This study retrospectively analyzed four patients with locally advanced or advanced pancreatic cancer to evaluate the clinical efficacy and safety of high-intensity focused ultrasound(HIFU)ablation combined with chemotherapy as a neoadjuvant and conversion therapy.All cases were reviewed and individualized treatment plans were formulated through a multidisciplinary team evaluation.All patients received HIFU plus gemcitabine and nab-paclitaxel chemotherapy,with assessments of tumor volume,vascular involvement,surgical conversion,symptom relief,and adverse events.Three patients achieved marked tumor shrinkage and reduction of vascular invasion,enabling successful R0 resection without recurrence during follow-up.The remaining patient achieved disease stability,significant pain relief,and maintained good quality of life under repeated HIFU therapy.All treatments were well tolerated,and no severe adverse reactions occurred.The combination of HIFU and chemotherapy demonstrated synergistic local and systemic effects,effectively achieving tumor downstaging,improving resectability,and alleviating symptoms.As a safe,noninvasive,and repeatable therapeutic approach,this strategy offers a promising option for patients with advanced pancreatic cancer.Further large-scale prospective studies are warranted to validate its long-term efficacy and elucidate underlying mechanisms.

Background and Aims:Infected necrotizing pancreatitis(INP),particularly with diffuse distribution,is a life-threatening condition.The optimal initial intervention-minimally invasive step-up therapy vs.direct open necrosectomy-remains controversial.Moreover,the impact of necrosis morphology("wet"or"dry")and the presence of severe acute pancreatitis(SAP)on treatment selection has not been fully clarified.This study aimed to compare the efficacy and safety of these two approaches in diffuse INP and to evaluate the guiding value of CT-based necrosis type and SAP status in clinical decision-making.Methods:A retrospective analysis was conducted on 458 patients with diffuse INP admitted to the Third Xiangya Hospital of Central South University from January 2012 to March 2023.Patients were divided into a minimally invasive step-up group(n=256)and a direct open surgery group(n=202).SAP was defined according to the determinant-based classification,and necrosis was categorized as"wet"or"dry"based on CT features.The primary endpoint was a composite of death or major complications,while secondary endpoints included mortality,length of hospital stay,and incision-related complications,were compared between the two groups,with subgroup analyses performed accordingly.Results:Overall,the open surgery group had higher rates of the primary endpoint(62.4%vs.48.1%,P=0.003)and mortality(27.2%vs.16.8%,P=0.008)compared with the step-up group.Among SAP patients,the step-up approach resulted in a significantly lower primary endpoint rate(66.7%vs.97.7%,P=0.003).In non-SAP patients,the primary endpoint rates were similar,but open surgery was associated with a shorter hospital stay[(36.5±10.4)d vs.(45.6±18.6)d,P<0.001]and higher incidences of wound infection and incisional hernia(both P<0.001).Multivariate analysis identified infection onset time,effusion characteristics,gas bubbles,and necrosis location as independent predictors of prolonged hospitalization in the step-up group(all P<0.05).Patients with"wet"necrosis benefited more from the step-up approach,whereas those with"dry"necrosis experienced shorter hospitalization following open surgery.Conclusion:For diffusely distributed INP,treatment strategies should be individualized based on SAP status and necrosis liquefaction/imaging characteristics.The step-up minimally invasive approach is preferred for SAP patients and those with"wet"necrosis on CT,while direct open necrosectomy may be advantageous for"dry"necrosis(particularly with limited liquefaction)by shortening hospital stay and reducing certain major outcomes,though at the cost of increased incision infection and incision herina.CT imaging features and SAP classification can serve as valuable tools for risk stratification and guiding individualized timing and modality of intervention.
