Objective: To explore the intervention effects of different exercise modalities on executive function in school aged children, providing references for formulating exercise prescriptions to promote school aged children executive function. Methods: A systematic literature search was conducted using PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP and CBM to identify studies on the effects of exercises on executive function in school aged children. The search period spanned from the database inception to August 2025. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Network Meta analysis was performed using Stata 16.0. Results: A total of 51 studies involving 5 710 school aged children and seven modalities of exercises(control group,small ball sports,large ball sports,aerobic exercise,combined exercise,sport game,gymnastic and dance sports) were finally included. Network Meta analysis showed that, in terms of inhibitory control development of school aged children, small ball sports ( SMD =-0.98,95% CI =-1.32 to -0.64 ), large ball sports ( SMD =-0.64,95% CI =-0.91 to -0.36), and mixed sports ( SMD =-0.26,95% CI =-0.50 to -0.02]) were more effective than the control group; in terms of working memory, largeball sports ( SMD =-1.26,95% CI =-1.88 to -0.65) and small ball sports ( SMD =-0.91,95% CI =-1.64 to -0.19) were superior to the control group; in terms of improving cognitive flexibility, large ball sports ( SMD =-1.02,95% CI =-1.28 to -0.76), gymnastics and dance sports ( SMD =-0.80,95% CI =-1.21 to -0.40), and small ball sports ( SMD =-0.75,95% CI =-1.15 to -0.36) were more effective than the control group (all P <0.05). Surface under cumulative ranking curve(SUCRA) showed that small ball sports had the highest value (SUCRA=98.9%) in improving inhibitory control, while large ball sports achieved the highest score(SUCRA=92.6%) in enhancing working memory, and large ball sports also had the highest value(SUCRA=94.7%) in promoting cognitive flexibility. Conclusions For developing inhibitory control in school aged children, small ball sports are recommended as a priority. For enhancing working memory and cognitive flexibility, large ball sports are recommended.

ObjectiveTo investigate the heterogeneity and transcriptomic characteristics of T-cell subsets in the liver of mice with nonalcoholic steatohepatitis （NASH） at the single-cell level using single-cell RNA sequencing （scRNA-seq）， and to provide a reference for studying the mechanism of action of T cells in NASH. MethodsSix male C57BL/6 mice were randomly divided into control group fed with regular diet and NASH group fed with methionine-choline-deficient （MCD） diet， with three mice in each group， and liver tissue was collected for scRNA-seq after 6 weeks of modeling. Specific differentially expressed genes were analyzed between T-cell subsets， and related analyses were performed， including dimension clustering， cell type annotation， t-distributed stochastic neighbor embedding （t-SNE）， violin plot， gene ontology （GO） functional enrichment analysis， and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis. Immunofluorescent staining was used to observe the expression of the T cell marker Tcrα and the specific marker genes Tcf7 and Cxcr6 in the liver of mice in the two groups. The independent-samples t test was used for comparison of continuous data between two groups. ResultsTwo T cell subsets were identified in the liver of mice， and the percentage of cluster 6 decreased from 58.5% in the control group to 48.7% in the NASH group. The top four specific genes were Nsg2， Cd8b1， Cd8a， and Tcf7. Tcf7， a characteristic marker gene for cluster 6， was expressed in 65% of cells in cluster 6， and therefore， cluster 6 was defined as Tcf7⁺ T cells. The GO and KEGG enrichment analyses showed that the differentially expressed genes of cluster 6 were involved in T cell activation， leukocyte adhesion， binding ubiquitin-like protein ligase， and the signaling pathways for Th17， Th1， and Th2 cell differentiation. The percentage of cluster 7 increased from 41.5% in the control group to 51.3% in the NASH group. The top four specific genes of cluster 7 were Cd40lg， Tcrg-C1， Il2rα， and Cxcr6. Cxcr6 was expressed in 90% of cells in cluster 7， and therefore， cluster 7 was defined as Cxcr6⁺ T cells. The GO and KEGG enrichment analyses showed that cluster 7 was involved in T cell activation， cytokine production， the T cell receptor signaling pathway， and the Th17 cell differentiation and MAPK signaling pathway. Immunofluorescence assay showed that compared with the control group， the NASH group showed a significant reduction in the area with positive co-expression of Tcf7 protein and Tcrα protein （1.80%±0.67% vs 0.33%±0.13%， P<0.05） and a significant increase in the area with positive co-expression of Cxcr6 protein and Tcrα protein （0.50%±0.09% vs 2.66%± 0.33%， P<0.001）. ConclusionThere is a reduction in the percentage of Tcf7⁺ T cells and an increase in the percentage of Cxcr6⁺ T cells in NASH mice， revealing the characteristics and differences of T cells in the liver of NASH mice.

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.

Objective To analyze the application of flipped classroom in the practical teaching of rehabilitation assessment courses for rehabilitation therapy majors,and to explore a new teaching method for rehabilitation therapy.Methods Eighty students majoring in rehabilitation therapy from the Department of Rehabilitation Medicine of Guangzhou Xinhua University in grade 2020 were selected as the research objects.They were assigned into observation group or control group according to the random number table method,with 40 cases in each group.The observation group adopted the flip classroom teaching mode,and the rehabilitation assessment course teaching based on flipped classroom was carried out,while the control group adopted the traditional teaching mode.The students'theoretical and operational assessment results,teaching effect,and teaching model satisfaction were analyzed.Results No statistically significant differences were found in theoretical test scores between the two student groups(by gender/course).The students in the observation group had higher theoretical scores[(80.25±11.65 vs 72.50±14.28)score].The observation group showed significantly higher satisfaction scores than the control group across all three dimensions:classroom learning enthusiasm,teacher-student interaction,and overall teaching satisfaction.(P<0.05).Conclusion The application of flipped classroom in the rehabilitation therapy teaching is helpful to improve the professional theoretical level of students,and to a certain extent,it is beneficial to improve the professional level of teachers.

The four MLB1 sequences of this study had 99.1% to 99.9% nt similarities with each other and 92.2% to 99.4% with those from other regions. The VA2 sequence of this study had 96.0% to 96.3% nt similarities with those from other regions. Phylogenetic analysis based on ORF2 region showed that the local HAstV-1 sequences were most closely related to Japanese strains, and had distinct topology with phylogenies based on ORF1a and ORF1b regions. Conclusion:The complete genome sequences of 11 HAstV strains are obtained, and the VA2 complete genome is found.

The research focus of diabetes, a common chronic metabolic disease, has shifted from individual factors to environmental factors at the population level. Epidemiological studies suggest an association between exposure to environmental pollutants and the risk of diabetes. Major environmental pollutants include organochlorine pesticides, polychlorinated biphenyls, phthalates and their metabolites, and arsenics, which primarily enter the human body through the skin, respiratory tract, and digestive system. Long-term exposure to these pollutants can affect the pathology of diabetes through various mechanisms, such as promoting insulin resistance, causing insulin secretion deficiencies, inducing oxidative stress-induced glucose metabolism disorders, and affecting DNA methylation. However, the potential damaging mechanism of the impact of environmental pollutants on diabetes remain unclear. Limitations such as insufficient sample sizes, uncertainties regarding exposure time and dosage, and differences between single and co-exposures. In the future, it is necessary to focus on exploring and analyzing the mechanisms of environmental pollutant exposure on diabetes to develop effective prevention strategies, control and reduce the incidence and development of diabetes, and provide new insights into its diagnosis and treatment.

By organizing and studying on the original works of LI Wenrong， this paper aimed to explore his theories and methods for treating liver diseases. LI Wenrong believes that the liver is easily prone to physiological disturbances， difficult to pacify， and can be compared to a “chariot” that moves horizontally and vertically， acting as a “general” for both civil and military affairs. Pathologically， liver diseases tend to spread to other organs， resulting in ever-changing pathological changes， often affecting emotional health. In terms of therapeutic methods， LI Wenrong proposes ten methods including draining fire to calm the liver， nourishing water to moisten wood， clearing metal to calm the liver， calming gallbladder and harmonizing liver， subduing yang with shell-drug， treating liver diseases by supplementing spleen， soothing the liver with sweetness， astringing the liver with sourness， relieving the liver with spiciness， and draining the liver with excess-fire. These methods have great guidance and reference value for contemporary clinical practice in traditional Chinese medicine.

Objective To analyze the seroepidemiology characteristics of Epstein-Barr virus(EBV)infection in children in Shenyang.Methods From June 2022 to May 2023,serum was collected from 12 083 children at Shengjing hospital of China Medical University.Serum capsid antigen(VCA)-IgM,VCA-IgG,EBV nuclear antigen-IgG(EBNA-IgG),and early antigen-IgG(EA-IgG)antibodies were detected using the LIAISION chemiluminescence immunoassay.EBV-DNA was detected using real-time PCR.Differences in antibody positivity rates between sexes,ages,and seasons of onset were compared.Results In 12 083 patients,the positive rates of VCA-IgM,VCA-IgG,EBNA-IgG,and EA-IgG were 9.95％(1 202/12 083),50.57％(6 110/12 083),46.03％(5 562/12 083)and 4.93％(596/12 083).The positive rates of VCA-IgM and EA-IgG were lower in male patients(9.09％and 4.44％,respectively)than in female patients(11.10％,5.60％;all P＜0.05).The differences in the positive rates for VCA-IgM,VCA-IgG,EBNA-IgG,and EA-IgG antibodies in children of different ages were statistically significant(all P＜0.05).Differences in the positive rates of VCA-IgG,EBNA-IgG,and EA-IgG antibodies were statistically significant when compared between seasons(all P＜0.05).Fourteen EBV antibody-positive combinations were detected,of which the main combination was VCA-IgG and EBNA-IgG double-positive,with a total of 4 741 cases(39.24％).Of the 3 712 children who underwent EBV-DNA detection testing,3 034(81.73％)were EBV-DNA-negative and 678(18.27％)were EBV-DNA-posi-tive.VCA-IgG and EBNA-IgG double positivity was the most common in EBV-DNA-negative and EBV-DNA-positive children,accounting for 983(26.48％)and 194 cases(5.23％),respectively.Conclusion Both VCA-IgG and EBNA-IgG antibodies are main positive in children with EBV infection in Shenyang.The positive rate of EBV antibodies is lower in boys than in girls.The positive rates of EBV anti-bodies differ in children of different ages and seasons of onset.

Sepsis is a complex syndrome caused by multiple pathogens and involves multiple organ failure, particularly spleen dysfunction. In 2017, the worldwide incidence was 48.9 million sepsis cases and 11 million sepsis-related deaths were reported (Rudd et al., 2020). Inflammation, oxidative stress, and apoptosis are the most common pathologies seen in sepsis. Liensinine (LIE) is a bisbenzylisoquinoline-type alkaloid extracted from the seed embryo of Nelumbo nucifera. Lotus seed hearts have high content of LIE which mainly has antihypertensive and antiarrhythmic pharmacological effects. It can exert anti-carcinogenic activity by regulating cell, inflammation, and apoptosis signaling pathways (Manogaran et al., 2019). However, its protective effect from sepsis-induced spleen damage is unknown. In this research, we established a mouse sepsis model induced by lipopolysaccharide (LPS) and investigated the protective effects of LIE on sepsis spleen injury in terms of inflammatory response, oxidative stress, and apoptosis.
