Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder among women of reproductive age. Hyperandrogenism (HA), one of its core pathological features, is closely associated with the clinical manifestations and metabolic complications of the disease. Current western medical treatments for PCOS-HA mainly include anti-androgen therapy and ovulation induction, such as short-acting oral contraceptives like Diane-35 and Yasmin. However, long-term use of these medications may result in adverse reactions like increasing the risk of liver dysfunction and exacerbating lipid metabolism disorders, with unsatisfactory long-term efficacy when used alone. Traditional Chinese medicine offers unique advantages in the treatment of PCOS-HA due to its holistic approach and multi-target regulatory mechanisms. In the view of traditional Chinese medicine, PCOS-HA is classified under the categories such as "delayed menstruation", "amenorrhea", and "infertility", with kidney deficiency as the root, as well as liver stagnation and spleen deficiency as the manifestations. Phlegm and blood stasis are considered to be intertwined throughout the disease course. Modern studies have shown that traditional Chinese medicine is significantly effective in improving the androgen levels, restoring ovulation, and improving insulin resistance in PCOS-HA patients. Representative prescriptions, such as Erxian Tang, Jiawei Xiaoyaosan, Guizhi Fulingwan, and Cangfu Daotantang, exert therapeutic effects through various mechanisms including regulation of the hypothalamic-pituitary-ovarian axis, reduction of ovarian androgen synthase activity, improvement of insulin signaling pathways, and inhibition of inflammation and oxidative stress, which demonstrates the characteristics of comprehensive treatment with traditional Chinese medicine. Based on the perspectives of etiology and pathogenesis of traditional Chinese medicine, modern medical cognition, typical prescriptions, and action mechanisms, this paper reviewed the research progress of traditional Chinese medicine in the treatment of PCOS-HA, aiming to provide a reference for in-depth research and clinical applications in this field.

ObjectiveTo investigate the therapeutic efficacy of Qizhi Tongluo granules on proteinuria in membranous nephropathy (MN) and its potential protective effects and underlying mechanism against endoplasmic reticulum stress. MethodsAfter 70 Sprague-Dawley (SD) rats were adaptively fed for one week, the MN rat model was established by injecting cationic bovine serum albumin (C-BSA) into the tail vein. Rats were divided into the normal group, model group, low-dose Qizhi Tongluo granules group (2.43 g·kg-1), medium-dose group (4.86 g·kg-1), high-dose group (9.72 g·kg-1), and benazepril group (0.01 g·kg-1), with 10 rats in each group. Treatment was administered for four weeks. The 24-hour urinary total protein (UTP) content, as well as the levels of reactive oxygen species (ROS), malondialdehyde (MDA), and glutathione peroxidase (GPX) in renal tissues, were measured. Renal pathological changes were assessed using immunoglobulin G (IgG) staining, periodic acid-silver methenamine (PASM) staining, and transmission electron microscopy (TEM). The localization and expression levels of glucose-regulated protein 78 (GRP78), phosphorylated inositol-requiring enzyme 1α (p-IRE1α), phosphorylated protein kinase R-like endoplasmic reticulum kinase (p-PERK), activating transcription factor 4 (ATF4), nuclear factor erythroid 2-related factor 2 (Nrf2), and 2'-5' oligoadenylate synthetase-like protein 1 (OASL1) in rat kidneys were detected by immunohistochemistry (IHC). The mRNA and protein expression levels of Nrf2, thioredoxin 1 (Trx1), thioredoxin-interacting protein (TXNIP), and OASL1 in rat kidneys were measured using real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot analysis. ResultsCompared with the normal group, UTP levels were significantly increased in the model rats (P<0.05), with obvious renal pathological damage. GPX content levels were significantly decreased in renal tissue (P<0.05), while ROS and MDA content levels were significantly increased (P<0.05). The expression of GRP78, p-IRE1α, p-PERK, and ATF4 proteins was significantly increased in the kidneys (P<0.05), while the mRNA and protein expression levels of Trx1 and Nrf2 were significantly decreased (P<0.05). The mRNA and protein expression levels of TXNIP and OASL1 were significantly increased (P<0.05). Compared with the model group, the UTP levels of rats in the Qizhi Tongluo granules groups and the benazepril group decreased to varying degrees (P<0.05), and renal pathological damage was significantly alleviated. The GPX content in renal tissue was significantly increased (P<0.05), while the ROS and MDA levels were significantly decreased (P<0.05). The expression of GRP78, p-IRE1α, p-PERK, and ATF4 proteins in the kidney was significantly decreased (P<0.05). The mRNA and protein expression levels of Trx1 and Nrf2 were significantly increased (P<0.05), while the mRNA and protein expression levels of TXNIP and OASL1 were significantly decreased (P<0.05). ConclusionQizhi Tongluo granules alleviates proteinuria in MN rats by modulating the Nrf2/OASL1 signaling pathway in renal tissues to reduce endoplasmic reticulum stress, which represents its underlying mechanism.

Objective:
There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression.
Methods:
This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale.
Results:
The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05).
Conclusion
EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

Objective To analyze the relationship between the expression of ferroptosis markers in the tumor microenvironment(TME)and the prognosis of transcatheter arterial chemoembolization(TACE)for hepatocellular carcinoma(HCC).Methods This prospective observational study included 100 HCC patients who received TACE treatment at Langfang Hospital of Traditional Chinese Medicine from March 2019 to June 2021 as the study subjects.The levels of 8-isoprostaglandin F2α(8-iso-PGF2α),4-hydroxy-2-nonenal(4-HNE),8-hydroxy-2'deoxyguanosine(8-OH-dG)and hepcidin in plasma were evaluated by ELISA kit at baseline(1 day before TACE),1 day after TACE and 4~8 weeks.The changes of ferroptosis related markers during TACE treatment were compared.The difference between the level of 8-iso-PGF2α,4-HNE and the baseline 1 day after TACE treatment was recorded as △8-iso-PGF2α,△4-HNE.Results Compared with the baseline,the levels of 8-iso-PGF2α and 4-HNE increased significantly and the level of hepcidin decreased significantly one day after TACE treatment,and the differences were statistically significant(t=8.03,16.29,2.92,all P<0.05).Compared with 1 day after treatment,the levels of 8-iso-PGF2α,4-HNE decreased and the level of 8-OH-dG increased at 4~8 weeks after TACE treatment,and the differences were statistically significant(t=9.12,17.17,2.63,all P<0.05).Multivariate COX analysis showed that △8-iso-PGF2α,△4-HNE and 8-iso-PGF2α 1 day after TACE treatment were independent factors affecting the overall survival after TACE(Wald χ2=5.205,13.801,6.054,all P<0.05).The survival time of patients with △4-HNE>2.01 μg/ml was significantly longer than that of patients with △4-HNE≤2.01 μg/ml(Log-rank=5.718,P=0.017),and that of patients with△8-iso-PGF2α>1.75ng/ml was sig-nificantly longer than that of patients with△8-iso-PGF2≤1.75ng/ml(Log-rank=4.163,P=0.041).Conclusion The prognosis of HCC patients who are in a state of high ferroptosis(4-HNE and 8-iso-PGF2 increased)at 1 day after TACE treatment is better,which indicate that ferroptosis mediated HCC death induced by TACE treatment.
