Objective To systematically analyze the policies on children's physical activity,sedentary behavior,obesity prevention and control,and functional and mental health issued by international organizations and China;as well as the health behavior intervention models targeting physical activity and psycho-behavioral health for overweight or obese children from the functional perspective of International Classification of Functioning,Disability and Health(ICF).Methods A total of six international policy documents and three national policies were included.Three health behavior intervention models,namely Behavioral Susceptibility Theory(BST),Family-based Behavioral Treatment(FBBT)and Healthy Lifestyles Programme(HeLP),were discussed focusing on the opportunity,motivation,and function and capability.Results International policies formed a closed loop in four domains:strategy,technology,governance and monitoring.The United Nations Children's Fund also emphasized the importance of psychosocial and equity dimensions.Chi-na's relevant policies attached great importance to the monitoring and implementation of children's physical activ-ity,as well as issues such as physical activity and mental health stressing the personalized needs of obese chil-dren and the integration of physical activity with health-related psycho-behavioral interventions.BST set up fun moderate-to-vigorous physical exercises and parent-child emotional eating education before meals,mainly target-ing children susceptible to high food responsiveness,to regulate energy balance and strengthen motivation.FBBT reshaped family environmental opportunities through behavioral control,family contracts and parental modeling,to enhance children's self-efficacy and physical activity.HeLP integrated drama therapy and peer sup-port into classroom and extracurricular activities,to create a positive atmosphere to enhance a sense of belonging and sustained participation.These intervention models improved functional and psycho-behavioral health through environmental empowerment and motivation activation.Conclusion The global policy framework has expanded from controlling body mass index to multi-dimensional health goals of improving function and psycho-behavioral health.Current international and national policies have cov-ered the four key dimensions of strategic goals,behavioral guidelines,governance measures and monitoring indi-cators.The physical activity-related health behavior intervention models,such as BST,FBBT and HeLP,may in-crease the physical activity level of obese children and promote psycho-behavioral health by expanding environ-mental opportunities,enhancing psychological motivation and improving physical function and capability.

Objective To evaluate the benefits of physical activity on the physical health,mental health and health behaviors related to physical activity in obese and overweight children and adolescents.Methods Following the PRISMA guidelines,a systematic search was conducted in Web of Science,PubMed,Scopus,PsycINFO,Cochrane Library and CNKI for systematic reviews or meta-analyses published between 2016 and 2024 in Science Citation Index Q4 or higher journals,related to physical activity or exercise for physical and mental health in obese and overweight children and adolescents.They were assessed using AMSTAR 2 tool to en-sure that the methodological quality was medium to high.Results A total of eight systematic reviews and meta-analyses involving 24 567 participants were included.Six studies were of high quality,and two were of moderate quality.In terms of physical health,combined aerobic and resis-tance exercise interventions demonstrated the most significant improvements in reducing body mass index(BMI)and body fat percentage.Moderate-to-high-intensity exercise performed three times per week,at least 60 minutes per session,over twelve weeks or longer significantly reduced BMI and body fat percentage in obese and over-weight children while improving cardiorespiratory endurance and muscular strength.In terms of mental health,physical activity was positive in reducing depression and anxiety,and improving self-esteem in children and ado-lescents.Activities such as dance,outdoor adventure programs and team sports notably enhanced social skills and emotional well-being.For neurodevelopmental disorders,low-intensity activities like aquatic walking and yoga significantly improved self-regulation and social interaction abilities.In terms of health-related behaviors,physi-cal activity interventions promoted the development of exercise habits,improved social interaction skills,in-creased physical activity participation,reduced sedentary behavior,and enhanced health and physical activity knowledge.In terms of multi-modal interventions,programs combining aerobic exercise with nutrition education or psychological counseling were more effective in improving overall health compared to single-modal interven-tions.Health-promoting schools(HPS)approach,integrating school,family and community involvement,effec-tively increased students'physical activity levels,reduced obesity rates,and improved mental health outcomes.Conclusion Physical activity is benefit in physical and mental health for obese and overweight children and adolescents.Moderate-to-high-intensity aerobic and resistance training,dance,and outdoor activities are effective interven-tions for improving body composition and mental health.Multi-modal interventions and HPS strategies can yield sustained health benefits.

Objective:To investigate the predictive factors of poor prognosis in children with acute kidney injury (AKI) treated with renal replacement therapy (RRT).Methods:In this retrospective case-control study, the clinical data were collected from 134 pediatric patients (82 male, 52 female) with AKI treated with RRT in six tertiary hospitals from May 2015 to June 2018. According to the serum creatinine level at discharge, the patients were divided into the favorable outcome group and unfavorable outcome group. The data of sex, age, primary diseases, AKI stage, time from diagnosis of AKI to start of RRT (h) and whether to start RRT within 24 hours, urine volume and complications between the two groups were compared. Continuous variables were compared by t test and Mann-Whitney U test, and percentage or proportions were compared by Chi square test. The predictive factors of adverse prognosis were analyzed by using univariate and unconditional binary logistic regression analysis. Results:The average age of the 134 AKI patients was (6±4) years. There were 114 patients (85.0%) in the favorable outcome group and 20 patients (15.0%) in the unfavorable outcome group. No statistically significant differences were found between the two groups in terms of sex (χ 2=2.596, P=0.107), age ( t=0.718, P=0.474), primary disease (χ 2=2.076, P=0.722), AKI stage (χ 2=0.004, P=0.998), time from diagnosis of AKI to start RRT (h) ( P=0.745), whether to start RRT within 24 hours (χ 2=0.016, P=0.899), urine volume (χ 2=3.118, P=0.374), fluid overload (χ 2=0.014, P=0.905), multiple organ dysfunction syndrome (MODS) (χ 2=2.972, P=0.085), acidosis (χ 2=3.204, P=0.073), hyperkalemia (χ 2=2.829, P=0.093), the level of blood urea nitrogen ( t=1.351, P=0.179) and serum creatinine ( P=0.901) at the beginning of RRT. In the unfavorable outcome group, the proportion of patients with mechanical ventilation (45.0% (9/20) vs. 12.3% (14/114), χ 2=12.811, P<0.01) and the incidence of extra organ injury (≥3) (30.0% (6/20) vs. 10.5% (12/114), χ 2=6.365, P=0.041) were higher than those in the favorable outcome group. Logistic regression analysis showed that mechanical ventilation ( OR=12.540, 95 %CI: 3.376-46.577, P<0.01) and hyperkalemia ( OR=4.611, 95 %CI: 1.265-16.805, P=0.021) were the predictive factors of poor prognosis in patients with AKI treated with RRT. Conclusion:Mechanical ventilation and hyperkalemia may predict a poor prognosis in AKI patients treated with RRT.

Objective: To evaluate the efficacy and side effects of priming regimen with pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in the treatment of initial treatment elderly patients with acute myeloid leukemia (AML). Methods: Thirty-five elderly patients with early-stage AML (non-M₃) who received pre-excitation chemotherapy in Yancheng Third People's Hospital from February 2015 to January 2019 were retrospectively analyzed. According to the different granulocyte colony-stimulating factor (G-CSF) in the chemotherapy regimen, 15 cases were in PEG-rhG-CSF group, 6 mg PEG-rhG-CSF was used alone on day 0 by subcutaneous injection; 20 cases were in recombinant human granulocyte colony-stimulating factor (rhG-CSF) group, 200 μg/m² rhG-CSF was used per day from day 0 to day 13 by subcutaneous injection, rhG-CSF was suspended or continued according to the number of white blood cells. In addition, both groups were given priming regimen with cytarabine and arubicin, or cytarabine and harringtonine. The efficacy and adverse reactions of the two groups were compared. Results: In the PEG-rhG-CSF group, there were 5 cases of complete remission, 6 cases of partial remission, 4 cases of non-remission, and 11 cases were effective. In the rhG-CSF group, there were 8 cases of complete remission, 7 cases of partial remission, 5 cases of non-remission, and 15 cases were effective. There was no significant difference in the efficacy between the two groups (χ ²= 0.012, P= 0.911). In terms of adverse reactions, the incidence of infectious fever, bone pain, duration of neutropenia, and duration of thrombocytopenia were not statistically significant (all P > 0.05). Conclusions In the pre-excitation chemotherapy for AML, the clinical efficacy and adverse effects of PEG-rhG-CSF are similar to rhG-CSF. However, the use of PEG-rhG-CSF can simplify the operation and reduce the pain and risk of local infection during chemotherapy.
