Polycystic ovary syndrome (PCOS) is a common gynecological endocrine and reproductive disorder,with the main clinical manifestations including ovulation failure,insulin resistance,hyperandrogenism,and obesity. Its occurrence and development are closely related to cellular regulatory mechanisms such as apoptosis,autophagy,oxidative stress,and inflammatory response. Autophagy,as a clearance mechanism that maintains cellular homeostasis,plays a crucial role in maintaining the growth,development,and maturation of oocytes. Exploring the mechanism of autophagy during the occurrence and development of diseases can help develop treatment methods for PCOS by regulating autophagy. Studies have shown that autophagy plays an important role in the pathogenesis of PCOS,and it can affect the occurrence and development of PCOS through multiple pathways,levels,and targets. Traditional Chinese medicine (TCM) regulates autophagy in ovarian granulosa cells or endometrium of patients with PCOS by targeting the expression of autophagy signaling pathways,regulatory factors,and non-coding single-stranded RNA molecules,thereby alleviating inflammation,regulating metabolism disorders,and balancing hormone levels in PCOS. Accordingly,TCM can ameliorate pathological conditions such as insulin resistance,hyperandrogenism,and ovulation failure in PCOS. This article summarizes the TCM formulas and extracts for the treatment of PCOS,as well as the main autophagy pathways and regulatory factors involved,aiming to provide reference and suggestions for the future treatment of PCOS with TCM by regulating autophagy.

ObjectiveTo study the tumor inhibition and T helper cell (Th)1/Th2 balance regulation effect of modified Wenyang Sanjie prescription on lung cancer tumor-bearing mice and to elaborate its mechanism. MethodsA mouse model bearing a lung cancer tumor was established by subcutaneous injection of Lewis lung cancer cells into the armpit and was randomly divided into lung cancer model group, low-dose, medium-dose, and high-dose groups of modified Wenyang Sanjie prescription, and positive control group, with 12 mice per group. The low-dose, medium-dose, and high-dose groups of modified Wenyang Sanjie prescription were given modified Wenyang Sanjie prescription by dosing at 2.5, 5, 10 g·kg-1, once a day, respectively. The positive control group was intraperitoneally injected with cisplatin (2 mg·kg-1), once every other day, for a total of 30 days. Serum interferon (IFN)-γ, interleukin (IL)-2, IL-4, IL-6, and IL-10 were determined by enzyme-linked immunosorbent assay (ELISA), and spleen index, thymus index, and tumor growth inhibition rate were calculated. Tumor microvascular density was determined by immunohistochemistry, and tumor hypoxia inducible-factor (HIF)-1α, epidermal growth factor receptor (EGFR), and vascular endothelial growth factor (VEGF) mRNA were determined by Real-time quantitative polymerase chain reaction (PCR). The protein levels of HIF-1α, EGFR, and VEGF were determined by Western blot. ResultsCompared with lung cancer model group, IFN-γ and IL-2 were increased in the modified Wenyang Sanjie prescription groups and positive control group, while IL-4, IL-6, IL-10, spleen index, thymus index, tumor weight, and tumor microvascular density were decreased, as well as HIF-1α, EGFR, and VEGF mRNA and protein levels (P<0.05). Compared to the low-dose group of modified Wenyang Sanjie prescription, IFN-γ and IL-2 were increased in the medium-dose and high-dose groups of modified Wenyang Sanjie prescription, while IL-4, IL-6, IL-10, spleen index, thymus index, tumor weight, and tumor microvascular density were decreased, as well as HIF-1α, EGFR, and VEGF mRNA and protein levels (P<0.05). IFN-γ and IL-2 were increased in the high-dose group of modified Wenyang Sanjie prescription compared to the medium-dose group of modified Wenyang Sanjie prescription, and IL-4, IL-6, IL-10, spleen index, thymus index, tumor weight, and tumor microvascular density were decreased, as well as HIF-1α, EGFR, and VEGF mRNA and protein levels (P<0.05). ConclusionModified Wenyang Sanjie prescription can significantly inhibit microangiogenesis, regulate Th1/Th2 balance, inhibit tumor growth, and significantly inhibit the progression of lung cancer in mice.

Chinese Journal of School Health 2025;46(9):1282-1286
Objective:
To analyze the epidemiological characteristics and changing trends of non suicidal self injury (NSSI) behaviors among middle school students in Jiading District of Shanghai, from 2015 to 2023, so as to provide a basis for the development of NSSI prevention and control measures among students.
Methods:
Using a stratified cluster random sampling method, a total of five times for Shanghai Adolescent Health Risk Behavior Surveys were conducted for every two years in Jiading District of Shanghai from 2015 to 2023. A total of 5 231 middle school students from junior high schools and senior high schools were selected for questionnaire surveys. Intergroup comparisons were performed using the x 2 test or the χ 2 trend test, and the JointPoint 5.0 software was used to analyze the changing trends, with the annual percent change (APC) used for evaluation. A binary Logistic regression model was employed to analyze the related factors of NSSI behavior among middle school students.
Results:
In 2023, the reported NSSI rate among middle school students in Jiading District was 14.2%. The rate was significantly higher among junior high school students (17.1%) than that among senior high school students (11.1%), and higher among females (19.2%) than that among males (10.0%) ( χ 2=10.04, 23.21, both P <0.01). From 2015 to 2023, the overall reported NSSI rate showed an increasing trend, rising from 8.6% in 2015 to 14.2% in 2023 ( χ 2 trend =22.25), with an APC of 6.64% ( t =3.49), and the APC for girls was 9.79 % ( t =3.20) (all P <0.05). Among students reporting NSSI, the proportion experiencing ≥6 episodes increased from 10.8% in 2015 to 19.2% in 2023 ( χ 2 trend =6.57, P <0.05). Multivariate Logistic regression analysis indicated that girls, junior high school students, those with insomnia, depressive emotion and drinkers had higher risks of NSSI, compared to boys, senior high school students, those without insomnia, non depressive emotion students and non drinkers ( OR =1.71, 1.96, 3.44, 4.76, 1.77, all P < 0.05 ).
Conclusions
The reported rate of NSSI among middle school students in Jiading District of Shanghai, increased annually from 2015 to 2023, and the proportion of repeated NSSI also showed an upward trend. Early intervention measures targeting middle school students, especially junior high school students and females, should be implemented to prevent and control its occurrence and development.

OBJECTIVE:
In order to enhance the efficacy of anti-breast cancer, paclitaxel nanoparticles (PTX NPs) and polypyrrole nanoparticles (PPy NPs) were combined with photothermal therapy and chemotherapy. At the same time, the two dosage forms of PTX NPs and PTX NPs gel were compared.
METHODS:
PTX NPs were prepared by self-assembly method, and then the cytotoxicity in vitro was investigated by Methyl thiazolyl tetrazolium (MTT) and other methods, and the efficacy and side effects in vivo were further investigated.
RESULTS:
The average hydrated diameter, PDI and electric potential of PTX NPs were (210.20 ± 1.57) nm, (0.081 ± 0.003) mV and (15.80 ± 0.35) mV, respectively. MTT results showed that the IC50 value of PTX NPs on 4 T1 cells was 0.490 μg/mL, while that of PTX injection was 1.737 μg/mL. The cell inhibitory effect of PTX NPs was about 3.5 times higher than that of PTX injection. The tumor inhibition rates of PTX NPs and gel were 48.64% and 56.79%, respectively. Together with local photothermal stimulation, the tumor inhibition rate of the PTX NPs reached 91.05%, surpassing that of the gel under the same conditions (48.98%), moreover, the organ index and H&E staining results of PTX NPs showed a decrease in toxicity.
CONCLUSION
This combination therapy can significantly enhance the effect of anti-breast cancer, and the synergistic effect of chemotherapy and light and heat provides a feasible and effective strategy for the treatment of tumor.

Objective:To investigate the clinicopathological features and treatment of gastric alpha-fetoprotein (AFP)-producing adenocarcinoma with SWI/SNF complex deletion.Methods:Four cases of gastric AFP-producing adenocarcinoma with SWI/SNF complex deletion diagnosed in Zhongshan Hospital of Fudan University from January 2021 to December 2022 were collected, and their histomorphological characteristics, immunohistochemical (IHC), in situ hybridization of Epstein-Barr virus-encoded RNA (EBER), next-generation sequencing results, clinicopathological features and treatment were summarized, and literature review was conducted.Results:Among the 4 patients, there were three males and one female. They presented with abdominal pain, belching and melena. Serum AFP was significantly elevated in three patients, and endoscopy showed ulcerative lesions. Microscopically, the tumor cells showed mainly diffuse flaky or nest-like growth and typical characteristics of hepatoid adenocarcinoma. In two cases there were adenoid growth, and the tumor cells in these areas possessed clear cytoplasm, suggesting enteroblastic differentiation. The tumor cell nuclei were pleomorphic with large nucleoli and brisk mitoses. The IHC results showed that the tumor cells expressed AFP, GPC3 and SALL4, and there was retained expression of broad-spectrum keratin (CKpan) and E-cadherin. IHC detection of SWI/SNF complex subunits, namely INI1 (SMARCB1), BRG1 (SMARCA4), BRM (SMARCA2), ARID1A protein was performed. In all four cases the hepatoid adenocarcinoma region and enteroblastic differentiation region showed SMARCA2 deletion, and one case with enteroblastic differentiation also showed ARID1A deletion. SMARCB1 and SMARCA4 deletions were not seen. All the four cases were diffusely positive for p53 protein, and the Ki-67 proliferation index was 80%-90%. There were no mismatch repair deletion detected; one cases showed HER2 was strongly positive (3+), and EBER was negative. None of the four cases had mutations in the SWI/SNF complex-related subunits detected by next-generation sequencing. Among the four patients, two underwent palliative surgery due to distant metastasis at the time of surgery, two underwent radical resection. Postoperative adjuvant chemotherapy was given to three patients.Conclusions:AFP-producing adenocarcinoma is a rare subtype of gastric cancer, which can be combined with SWI/SNF complex deletion, and the pathomorphological manifestations are different from the classical SWI/SNF complex deletion of undifferentiated carcinoma with rhabdoid phenotype.

There is no unified international guidelines or consensus on seizures and epilepsy following acute stroke reperfusion therapy so far.In this review,we briefly summarize its definitions and mechanisms.Post stroke epilepsy after reperfusion treatment is defined as patients with ischemic stroke who have received intravenous thrombolysis and/or endovascular therapy,without other definitive causes or epilepsy history before stroke,have at least two epileptic seizures occurred within 7 days of stroke onset,or at least one epileptic seizures occurred within 30 days of stroke onset.The incidence rate of epilepsy after intravenous thrombolysis is about 6.4%-20.6%,and arterial thrombectomy is about 5%.The pathophysiological mechanism of post stroke epilepsy after reperfusion treatment may be related to local hyperfusion,epileptogenic properties of tPA and hemorrhagic transformation.Higher stroke severity,cortical involvement,middle cerebral artery infarction,and early post-stroke seizures may be predictive factors for post-stroke epilepsy after reperfusion therapy.Levetiracetam and lamotrigine may be effective drugs for post-stroke epilepsy after reperfusion therapy.Sustained seizures after thrombolysis may increase the risk of death.
