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.

The symptoms of allergic diseases are complex and changeable, and the pathogenesis is complex and difficult to distinguish, and the prevalence of allergic diseases has gradually increased in recent years. Due to the relative limitations of Western medical treatment, in order to further meet the clinical treatment goals, the "lung being responsible for regulating visceral activities" is now used as the theoretical basis, combined with modern medicine, to explore the pathogenesis and etiological mechanism of this disease. Based on the classics, it is proposed that allergic diseases have four characteristics: "onset of allergies, seasonality of disease onset, diversity of symptoms, and recurrence of recovery", and summarized the etiology and pathogenesis as "stagnation of incubative pathogenic factors and disharmony between the nutritive and defensive levels, imbalance of waterways and obstruction of phlegm and dampness, a dysfunction in the pivotal qi flow leading to malnourishment of the skin and hair, the intermingling of cold and heat leads to the dysfunction of the orifices, a disorder of the blood-governing organs leads to extravasation of blood", and advocated that the treatment should take into account the symptoms, syndromes, viscera, and seasons, and clarify the syndromes, which would provide a new research idea for the exploration of the TCM connotation of this disease.

OBJECTIVE To investigate the effects of ginsenosides as P-glycoprotein(P-gp)substrates in combination with paclitaxel on the proliferation and migration of colon cancer Caco-2 cells.METHODS Bio-layer interferometry(BLI)technology was used to detect the constants of ginsenosides and P-gp.Network molecular docking was adopted to predict the binding affinity energy of ginsenosides and P-gp.Caco-2 cells were divided into paclitaxel 0,6.25,12.5,25,50,100 and 200 mg·L-1 groups,ginsenoside Rg3 0,6.25,12.5,25,50,100 and 200 mg·L-1 groups,and paclitaxel 5 mg·L-1+ginsenoside Rg3 0,25,50,100 and 200 mg·L-1 groups.After 48 h of incubation,the growth inhibition rate of Caco-2 cells was detected by MTT assay,and the interaction between the two drugs was quantitatively evaluated using the"one-belt,one-line"modle.Caco-2 cells were divided into the cell control group,paclitaxel 5 mg·L-1 group,ginsenoside Rg3 50 and 100 mg·L-1 groups,and paclitaxel 5 mg·L-1+ginsenoside Rg3 50 and 100 mg·L-1 groups.After 24 h of incubation,the proliferation and migration ability of the cells were detected by colony assay and Transwell migration assay.Caco-2 cells were then divided into the cell control group,quinidine 12.5 mg·L-1 group,and ginsenoside Rg3 6.25 and 12.5 mg·L-1 groups.After 4 h of incubation,the expression levels of P-gp and total protein were detected by ELISA.RESULTS The affinity constants of ginsenoside Rb1,Rg3,Rg5 with P-gp were all less than 10-3 mol·L-1,while that of ginsenoside CK with P-gp was 10-2 mol·L-1.There was no typical binding dissociation curve between ginsenoside Re and P-gp.The absolute binding affinities of ginsenosides Rg3 and Rg5 to P-gp were determined to be 8.5 kcal·mol-1 and 7.6 kcal·mol-1,respectively.Ginsenosides mixed with PTX 5 mg·L-1 inhibited the growth of colon cancer cells through synergy and addition,and the dose range of the syner-gistic effect was[0+5,43.15+5]mg·L-1;[164.51+5,200+5]mg·L-1,the additive effect dose ranged from[43.15+5,164.51+5]mg·L-1.The combination of the two drugs could significantly reduce the proliferation and migration ability of Caco-2 cells(P<0.01).The ELISA results showed a decrease in total protein and P-gp content in both the ginsenoside and quinidine groups(P<0.05).CONCLUSION Ginsenoside bind to and inhibit the activity of P-gp,synergizing with paclitaxel to reduce the proliferative and migratory abili-ties of Caco-2 cells.The combination of ginsenosides and paclitaxel enhances the sensitivity of Caco-2 cells to paclitaxel induced inhibition.The combined use of these two substances is expected to achieve better anticancer effects compared to paclitaxel alone.

OBJECTIVE To study the mechanism of Wenshen Tongdu Recipe in promoting the recovery of motor function in rats with spinal cord injury.METHODS A total of 144 SD rats were randomly divided into sham operation group,model group,predni-sone group,low-dose Wenshen Tongdu Recipe group,medium-dose Wenshen Tongdu Recipe group,high-dose Wenshen Tongdu Recipe group,3BDO group,and 3BDO+Wenshen Tongdu Recipe group(medium dose).The rat spinal cord injury model was estab-lished by modified Allen's method.Intervention began 1 day after modeling,and the drug was administered continuously for 14 days.During the drug administration period,the motor function of the rats in each group was evaluated by Basso-Beattie-Bresnahan(BBB)score and inclined plane test.On the 3rd,7th and 14th days after modeling,the pathological changes of the spinal cord tissues of the rats in each group were observed by HE staining;the expression levels of inflammatory factors IL-1β,IL-6,IL-4 and IL-10 in the serum of the rats in each group were detected by ELISA;the expression of Beclin 1,LC3B and p62 proteins was detected by immu-nohistochemistry;the expression of CD16 and CD206 proteins was detected by immunofluorescence staining;the expression of autoph-agy-related molecules(Beclin 1,LC3B)and Akt/mTOR pathway-related proteins in the spinal cord tissues was detected by Western blot.RESULTS Compared with the model group,the BBB score and angle of the inclined board test of rats in the medium-dose Wenshen Tongdu Recipe group were increased,and the disordered arrangement of spinal cord tissue,spinal cord vacuoles and inflam-matory infiltration were significantly improved,especially on the 14th day.Compared with the sham operation group,the expression levels of serum IL-1β and IL-6 in the model group increased(P<0.01),and the expression levels of IL-4 and IL-10 decreased(P<0.05,P<0.01);compared with the model group,the levels of IL-1β and IL-6 in the Wenshen Tongdu Recipe group were signifi-cantly decreased(P<0.01),and the levels of IL-4 and IL-10 were significantly increased(P<0.05,P<0.01);compared with the Wenshen Tongdu Recipe group,the serum IL-1β and IL-6 concentrations of mice in the 3BDO group increased(P<0.01),and the level of IL-10 decreased(P<0.05).Compared with the sham operation group,the M1/M2 ratio,P62 protein expression,p-Akt/Akt and p-mTOR/mTOR ratios in the spinal cord tissue of the rats in the model group were significantly increased(P<0.05,P<0.01),and the relative protein expression of Beclin1 was decreased(P<0.01);compared with the model group,the M1/M2 ratio,p-Akt/Akt and p-p70S6K/p70S6K ratios in the Wenshen Tongdu Recipe group were significantly decreased(P<0.01).Compared with the model group,the Beclin1 protein level in the 3BDO group was decreased,and the p-Akt/Akt and p-mTOR/mTOR ratios were increased(P<0.05,P<0.01).Compared with the Wenshen Tongdu Recipe group,the M1/M2 ratio in the 3BDO group and the 3BDO+Wen-shen Tongdu Recipe group increased(P<0.01),the positive rates of Beclin1 and LC3B proteins in the 3BDO group decreased signifi-cantly(P<0.01),and the p-p70S6K/p70S6K ratio in the 3BDO+Wenshen Tongdu Recipe group increased significantly(P<0.01).CONCLUSION Wenshen Tongdu Recipe may regulate microglial polarization through Akt/mTOR signaling pathway to acti-vate autophagy,promote the secretion of anti-inflammatory factors,reduce the release of pro-inflammatory factors,alleviate neuroin-flammatory response,and thus promote spinal cord injury repair.

Osteoarthritis(OA)is a common joint disease in clinical practice,and cartilage damage is a typical pathological change.The pathogenesis of OA is complex,and various adverse factors can lead to the occurrence of OA.Mitochondria are im-portant organelles within cells and play important roles in cellular physiological and pathological activ-ities.Mitochondrial quality control is an important regulatory mechanism in the body to maintain nor-mal mitochondrial structure and function,mainly including mitochondrial biogenesis,mitochondrial dynamics,mitochondrial autophagy,mitochondrial oxidative stress,and other forms.The imbalance of mitochondrial quality control in chondrocytes is closely related to the occurrence and development of osteoarthritis,and regulating the balance of mi-tochondrial quality control is a potential therapeu-tic point for osteoarthritis.The author reviewed rel-evant research literature in recent years to provide a review of the relationship between mitochondrial quality control and the occurrence and develop-ment of osteoarthritis,in order to provide new ideas and directions for the research and diagnosis and treatment strategies of osteoarthritis.

Objective:In alignment with the practical teaching objectives of Diseases of the Locomotor System and the competency requirements for graduates of military medical universities, this study conducted a multidimensional modification of the traditional objective structured clinical examination (OSCE) to provide a novel training mode that enhances the effectiveness of practical teaching of this course.Methods:The traditional OSCE was modified from the four dimensions of integration, individuality, immersion, and intelligence. The first three stations were set as "diagnosis" and the last three stations were set as "operation" to reflect the "integration" of diagnosis and treatment. The last station of "operation" was set as "medical cares of combat and training injuries" to reflect "individuality" of military medical training. The method of situation creation was used to reflect "immersion", and the application of intelligent terminals reflected "intelligence". The study involved 50 trainees who were assigned to either a modified OSCE group or a traditional teaching group through a random drawing process. The teaching effectiveness was assessed through evaluation of theoretical knowledge, practical skills, and participant satisfaction. The statistical analysis was conducted by SPSS 22.0, with parametric data assessed by t-tests and non-parametric data assessed by chi-square tests. Results:Before entering the department, there were no statistically significant differences in theoretical ( P=0.832) and practical ( P=0.513) scores between the two groups of trainees. However, after the internship, the modified OSCE group demonstrated significantly enhanced scores compared to the traditional teaching group, both in theory assessment [(93.88±1.92) vs. (90.76±2.85), P=0.001] and skill assessment [(94.32±1.25) vs. (91.68±2.82), P=0.001]. Additionally, the self-assessment of clinical capability improvement by the modified OSCE group was markedly higher across all dimensions than the traditional teaching group ( P=0.001). Furthermore, the evaluation conducted by basic combat unit on the job competency of graduated trainees indicated that the modified OSCE group outperformed the traditional teaching group in basic clinical diagnosis and treatment [(4.72±0.46) vs. (3.44±0.71), P=0.001], emergency management of combat and training injuries [(4.72±0.46) vs. (3.52±0.71), P=0.001], application of information technology [(4.44±0.71) vs. (3.91±0.80), P=0.029], basic military qualities [(4.40±0.71) vs. (3.92±0.91), P=0.043], mental health and resilience [(4.36±0.70) vs. (3.68±0.85), P=0.003], and the capacity for continuous learning [(4.64±0.70) vs. (3.83±0.76), P=0.001]. Conclusions:The modified OSCE teaching mode can better meet the practical teaching requirements for Diseases of the Locomotor System in the military medical university and thus holds promise for further application.

Objective To investigate the mechanism of Wenhe Decoction in the treatment of febrile seizures through network pharmacology based on NLRP3/Caspase-1/GSDMD signaling pathway;To conduct experimental verification.Methods The active components and targets of Wenhe Decoction were retrieved and screened through TCMSP,BATMAN-TCM,PubChem databases and SwissADME platform.The disease targets of febrile seizures were found in GenCards,OMIM and DisGeNET databases.The intersection targets of Wenhe Decoction and the disease and the active components corresponding to the intersection targets were imported into Cytoscape 3.7.2 software to construct the Chinese materia medica-active components-targets network.The intersection targets were submitted to the STRING database to construct a protein-protein interaction network,and then the intersection targets were imported into the Metascape database for GO and KEGG pathway enrichment analysis.The febrile seizures rat model was established,and Wenhe Decoction of 4.05,8.1 and 16.2 g/kg were given respectively by gavage for 21 days.The rats were placed in batches in(45±0.5)℃constant temperature water bath to induce convulsive seizures,and the convulsive latency time and convulsive duration of rats were recorded.The behavioral differences of mice were observed.The morphology of hippocampal tissue were observed by HE and Nissl staining.The ROS content of hippocampal tissue was detected by DHE fluorescent probe technology.The serum ATP,GABA,Glu,Caspase-1,GSDMD,IL-1β and IL-18 contents were detected by ELISA,and the expression of NLRP3 inflammasome-related protein in hippocampal tissue was detected by Western blot.Results Network pharmacology analysis obtained 98 active components of Wenhe Decoction and 1 838 targets.162 targets were obtained by intersecting with disease targets,the core components for the treatment of febrile seizures were β-sitosterol,quercetin,luteolin,trans-squalene,sitosterol,saponin,etc.,and the core targets were EGFR,TNF,JUN,MTOR,etc.,and mainly through the regulation of inflammatory response,apoptosis,mitochondrial function and energy metabolism,mediating anti-inflammatory pathways such as PI3K-Akt signaling pathway and calcium signaling pathway to exert anticonvulsant effects.The experimental results showed that Wenhe Decoction could prolong the convulsive latency and shorten the duration of convulsions in febrile seizures model rats,decrease the level of convulsions,and the pathological damage of hippocampal tissue was improved and damaged neurons were repaired.The serum contents of ROS,Glu,Caspase-1,GSDMD,IL-1β and IL-18 were significantly reduced,and ATP and GABA contents significantly increased.The protein expressions of NLRP3,ASC,pro-Caspase-1,pro-IL-1β and pro-IL-18 in hippocampal tissue significantly decreased.Conclusion Wenhe Decoction may intervene in febrile seizures rats through NLRP3/Caspase-1/GSDMD signaling pathway,inhibit pyroptosis to reduce the occurrence of neuroinflammation,and then affect the balance of neurotransmitters Glu and GABA to play a role in anti-febrile seizures and prevent brain tissue damage.

Objective To investigate the predictors of chronic pain after inguinal hernia surgery.Methods A total of 400 patients with inguinal hernia surgery in our hospital from August 2018 to May 2023 were selected as the study objects.Visual analog scoring(VSA)was used to evaluate postoperative acute pain within 24 h after surgery.The patients were divided into chronic pain group and non-chronic pain group according to whether chronic pain occurred after surgery.Thirty-seven patients with postoperative pain lasting more than 3 months were in the chronic pain group,and the remaining 363 patients were in the non-chronic pain group.Lasso-Logistic regression was used to analyze the predictors of acute and chronic pain after inguinal hernia surgery.Results Univariate analysis showed that there were significant differences in age,BMI,smoking history,preoperative groin pain,intraoperative nerve tension or injury,wound infection and postoperative acute pain between the chronic pain group and the non-chronic pain group(P＜0.05).The data were regularized by Lasso regression,and three representative risk factors of chronic postoperative pain,namely preoperative groin pain,intraoperative nerve pulling or injury,and postoperative acute pain,were selected.Multivariate Logistic regression analysis showed that:Preoperative groin pain(OR=2.548,95％CI1.150-5.647),intraoperative nerve tension OR injury(OR=4.435,95％CI2.084-9.436)and postoperative acute pain(OR=2.242,95％CI1.041-4.829)was the factor of chronic pain after operation(P＜0.05).Conclusion Preoperative groin pain,intraoperative nerve pulling or injury,and postoperative acute pain are the factors affecting chronic pain after inguinal hernia.Identifying high-risk groups and taking targeted measures are helpful to prevent and treat chronic pain after inguinal hernia.

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.
