OBJECTIVE To investigate the improvement mechanism of Huatan tongmai decoction on rats with polycystic ovary syndrome （PCOS） by regulating autophagy through phosphatidylinositol-3-kinase（PI3K）/protein kinase B（AKT）/mammalian target of rapamycin （mTOR） pathway. METHODS A total of 40 rats were randomly divided into blank group （purified water）， model group （purified water）， traditional Chinese medicine group [Huatan tongmai decoction， 24 g/（kg·d）] and chemical drug group [metformin， 0.16 g/（kg·d）]， with 10 rats in each group. Except for blank group， other groups were given a combination of high-fat diet and intragastric administration of 1 mg/kg letrozole suspension to establish PCOS rat model. After modeling， they were given relevant medicine or water intragastrically， once a day， for 42 consecutive days. After the last administration， the pathological and ultrastructural changes of ovarian tissue were observed. The levels of follicle stimulating hormone （FSH）， testosterone （T）， estradiol （E2） ，luteinizing hormone （LH） in serum were detected，and the LH/FSH ratio was calculated. mRNA expressions of Beclin-1， p62 and microtubule-associated protein 1 light chain 3 （LC3） in ovarian tissue were detected. The expressions of related proteins of PI3K/AKT/mTOR pathway and autophagy in rat ovarian tissues were also detected. RESULTS Compared with blank group， the pathological damage and ultrastructural changes of the ovarian tissue in the model group rats were obvious， and a large number of autophagosomes could be seen in cells. The levels of T and LH and the LH/FSH ratio in serum， as well as mRNA and protein expressions of Beclin-1 and LC3， were increased significantly （P＜0.05）， while the levels of E2 and FSH in serum， as well as mRNA and protein expressions of p62 and the phosphorylation levels of PI3K， AKT and mTOR proteins in ovarian tissue， were significantly decreased （P＜0.05）. Compared with model group， the pathological damage of ovarian tissue in the administration groups was significantly reduced， the number of autophagosomes was smaller， and the expression levels of the above indicators were significantly reversed （P＜0.05）. CONCLUSIONS Huatan tongmai decoction can inhibit autophagy in ovarian granular cells by activating the PI3K/AKT/mTOR pathway， regulate the secretion of sex hormones， alleviate pathological damage in ovarian tissues， and promote normal follicular development， thereby exerting an ameliorative effect on PCOS rats.

Objective To investigate influenza awareness of community residents in Nanchang under routine epidemic management using the Knowledge-Attitude-Practice(KAP)framework.Methods A structured questionnaire,including four do-mains(disease overview,prevention,diagnosis,and treatment),was designed and administered via street and online surveys from December 2023 to February 2024.Statistical analyses,including chi-square tests and logistic regression,were performed to identify determinant factors.Results A total of 303 valid questionnaires were retrieved,with an effective rate of approximately 94.7％.Community residents in Nanchang demonstrated a certain degree of understanding of the overview,prevention,diagno-sis,and treatment of influenza,although some gaps were identified.Univariate analysis revealed statistically significant differ-ences in influenza cognition scores among urban and rural residents(P＜0.05),residents with different educational levels(P＜0.05)and exposure levels to influenza education(P＜0.05).Multivariate regression analysis identified these as influencing fac-tors for influenza awareness.Conclusion Collaborative efforts from the government,individuals,and various societal sectors are essential to enhance the public's overall ability to prevent and control influenza.
