Objective: To explore the relationship between school sports environment and physical activity levels of middle school students, so as to provide theoretical and empirical support for optimizing school sports environment and enhance adolescent physical activity. Methods: Using multi-stage random cluster sampling, from September to December 2023, 1 329 junior and senior high school students from Xuancheng City of Anhui Province, Lianyungang City of Jiangsu Province, Wuhan City of Hubei Province, Qiqihar City and Suihua City of Heilongjiang Province, and Shenzhen City of Guangdong Province were selected. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) assessed students physical activity levels, and the questionnaire on the characteristics of school sports environment was developed to evaluate the factors of school sports environment. Multivariate ordered Logistic regression was performed to analyze the correlation between school sports environment factors and physical activity levels, and the analytic hierarchy process determined the weight of key influencing factors. Results: The results showed that weekly vigorous physical activity time was [60 (25, 90)] minutes, moderate physical activity time was [60 (30, 90)] minutes, light physical activity time was [105 (40, 200)] minutes, and sedentary behavior time was [ 3 300 (2 100, 4 500)] minutes, only 10.53% of the students met World Health Organization physical activity recommendations, and 89.69% of the students averaged >8 h daily sedentary time. Multivariate ordered Logistic regression showed that adequate sports equipment significantly promoted physical activity across all intensities and reduced sedentary time ( OR = 4.97, 11.54, 4.03, 0.11); diverse sports activities improved vigorous and moderate physical activity while reducing sedentary time ( OR =4.20, 14.06, 0.17); and peer encouragement was associated with increased low-intensity physical activities and decreased sedentary time ( OR =10.40, 0.15)( P <0.05). The analytic hierarchy process weighting analysis identified the top three influential factors related to physical activity among middle school students: sufficient sports equipment, varied physical education activities, frequent peer encouragement, the influence weight accounts for 23.55% , 14.18% and 11.77% of the total, respectively. Conclusion Key school sports environmental factors for adolescent physical activity level include ensuring adequate sports equipment and class availability, diversifying activity content, fostering peer support, and cultivating an active sports culture and a comprehensive approach encourage students participation in extracurricular physical activities.

Objective: To analyze the distribution and related factors of spherical equivalent(SE) anisometropia in school aged children in ethnic minority areas of Yunnan Province, so as to provide a scientific basis for the intervention and control of SE anisometropia. Methods: In October 2021,a total of 1 852 school aged children in three counties/cities(Lijiang City,Dali City,Xishuangbanna) in Yunnan Province were examined by multi stage cluster random sampling method for computer optometry visual acuity examination for non ciliary paralysis and questionnaire survey.Demographic characteristics, ocular biological parameters and SE data were obtained for SE anisometropia. Group comparisons were conducted using Mann-Whitney U test or Kruskal-Wallis H test, and Logistic regression was used to explore the related factors of anisometropia in SE. Results: The prevalence of SE anisometropia among school age children was 23.0%, and the prevalence was higher in girls (24.2%) than that in boys (21.6%). Compared with non anisometropic children, school aged children with SE anisometropia had longer axial length (AL) [24.03 (23.41, 24.76), 23.93 (23.26, 24.61) mm] and corneal curvature radius (CR) [43.42 (42.43, 44.42), 43.14 (42.23, 44.04)mm], SE[-1.75(-2.75,-1.00),-0.94(-2.63,-0.25)D], smaller spherical scope [-1.38(-2.38,-0.75),-0.75(-2.38,0)D], deeper anterior chamber depth(ACD)[3.77(3.62, 3.93), 3.72(3.55, 3.89)mm], and grater differences in AL[0.58(0.32,0.82), 0.13( 0.06 ,0.22)mm], ACD[0.05(0.02,0.08), 0.03(0.01,0.06)mm] and AL/CR[0.01(0.01,0.02), 0.01(0.00,0.01)]( Z =-22.47 to -2.41, all P <0.05). The results of Logistic regression showed that mild myopia( OR =2.74), moderate myopia( OR =3.52), and high myopia( OR =8.92) had a relatively high risk of anisometropia SE in school aged children(all P <0.05). Conclusion The prevalence of SE anisometropia in school aged children in ethnic minority areas of Yunnan Province is relatively high, and the prevalence and degree of anisometropia were closely related to myopia degree and related refractive parameters.

ObjectiveThe active ingredients， action targets， and signaling pathways of Cuscutae Semen to control premature ovarian failure were initially predicted by network pharmacology and molecular docking techniques， and an animal model of premature ovarian failure was constructed to explore the mechanism of Cuscutae Semen based on lipid and atherosclerosis signaling pathways. MethodThe effective components and corresponding targets of drugs were obtained from Traditional Chinese Medicines Systems Pharmacology Platform （TCMSP）， Swiss Target Prediction， Pharmmapper， and other databases. GeneCards database was used to collect disease-related targets. Venny2.1.0 online tool was used to screen out the intersection targets of drugs and diseases， and STRING database and Cytoscape v3.7.2 software were used to construct the network diagram of "drug-component-target" and protein-protein interaction （PPI）. The gene ontology （GO） and the Kyoto encyclopedia of genes and genomes （KEGG） enrichment analyses of the intersection targets were performed by running the R language script. The molecular docking technology was utilized to dock drug components with targets and visualize some of the docking results. The mice were randomly divided into a blank group， a model group， a Cuscutae Semen group， and an estradiol valerate group， and the ovarian premature failure model was prepared by chronic stress. The blank group and the model group were gavaged with the same amount of normal saline， and the Cuscutae Semen group was given a Cuscutae Semen decoction of 2.6 g·kg^-1·d^-1. The estradiol valerate group was given an estradiol valerate solution of 0.13 mg·kg^-1·d^-1. After four weeks， samples were collected， and hematoxylin-eosin （HE） staining was performed to observe the histopathological changes in the ovary. Serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， Muller's tube inhibitor/anti-Muller's tube hormone （AMH）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were determined by enzyme-linked immunosorbent assay （ELISA）. The expression levels of extracellular regulatory protein kinase （ERK）， nuclear transcription factor-κB p65 （NF-κB p65）， nuclear transcription factor-κB suppressor α （IκBα）， interleukin-1β （IL-1β）， IL-6， and tumor necrosis factor-α （TNF-α） were measured by Western blot. ResultA total of 171 targets of Cuscutae Semen for the prevention and treatment of premature ovarian failure were screened， mainly including tumor protein p53 （TP53）， protein kinase B1 （Akt1）， sarcoma （SRC）， tumor necrosis factor （TNF）， epidermal growth factor receptor （EGFR）， etc. KEGG pathway enrichment analysis predicts that Cuscutae Semen is mainly involved in lipid and atherosclerosis， TNF signaling pathway， and TP53 signaling pathway to control premature ovarian failure. The animal experiments show that compared with the premature ovarian failure model group， the Cuscutae Semen group can significantly upregulate AMH， E₂， and HDL-C （P<0.05， P<0.01）， significantly downregulate LH， TC， and LDL-C （P<0.01）， greatly reduce IL-1β， IL-6， and TNF-α protein levels， as well as ERK， NF-κB p65， and their phosphorylation levels （P<0.01）. ConclusionCuscutae Semen can regulate hormone levels and improve ovarian function through a multi-component， multi-target， and multi-pathway approach， and the mechanism may be related to the regulation of lipid and atherosclerosis signaling pathways.

Elemene, derived from Curcuma wenyujin, one of the "8 famous genuine medicinal materials of Zhejiang province," exhibits remarkable antitumor activity. It has gained wide recognition in clinical practice for effectiveness on tumors. Dr. XIE Tian, introduced the innovative concept of "molecular compatibility theory" by combining Chinese medicine principles, specifically the "monarch, minister, assistant, and envoy" theory, with modern biomedical technology. This groundbreaking approach, along with a systematic analysis of Chinese medicine and modern biomedical knowledge, led to the development of elemene nanoliposome formulations. These novel formulations offer numerous advantages, including low toxicity, well-defined composition, synergistic effects on multiple targets, and excellent biocompatibility. Following the principles of the "molecular compatibility theory", further exploration of cancer treatment strategies and methods based on elemene was undertaken. This comprehensive review consolidates the current understanding of elemene's potential antitumor mechanisms, recent clinical investigations, advancements in drug delivery systems, and structural modifications. The ultimate goal of this review is to establish a solid theoretical foundation for researchers, empowering them to develop more effective antitumor drugs based on the principles of "molecular compatibility theory".
