Dysregulation of the hypothalamic\u2013pituitary\u2013ovarian (HPO) axis and inflammatory responses are key pathological mechanisms, yet there are currently no specific therapeutic drugs available. Therefore, this study investigates the ameliorative effects of total flavonoids from\n                    <jats:italic>Rubus chingii<\/jats:italic>\n                    Hu (RHF) on HPO axis function and inflammatory response in a rat model of PCOS induced by letrozole. The results demonstrated that RHF restored the disrupted estrous cycle in PCOS rats. It significantly reduced ovarian weight, index, length, width, area, and volume. Moreover, RHF treatment decreased the ovarian mRNA levels of BCL\u20102\u2010associated X protein (Bax) and aspartate specific cysteine protease (Caspase)\u20103 while increasing that of B\u2010cell lymphoma\u20102 (Bcl\u20102), collectively ameliorating ovarian pathological changes. Concurrently, RHF significantly lowered serum levels of gonadotropin\u2010releasing hormone (GnRH), luteinizing hormone (LH), and testosterone (T), while elevating follicle\u2010stimulating hormone (FSH), estradiol (E\n                    <jats:sub>2<\/jats:sub>\n                    ), and sex hormone\u2010binding globulin (SHBG), indicating its potential to mitigate hypothalamic\u2013pituitary\u2013ovarian (HPO) axis dysfunction. Furthermore, RHF reduced peripheral blood counts of white blood cells (WBC), platelets (PLT), red blood cell distribution width (RDW), the neutrophil\u2010to\u2010lymphocyte (NLR), monocyte\u2010to\u2010lymphocyte (MLR), and platelet\u2010to\u2010lymphocyte (PLR) ratios, as well as serum interleukin\u201018 (IL\u201018), IL\u20101\u03b2, tumor necrosis factor\u2010\u03b1 (TNF\u2010\u03b1), and IL\u20106. In ovarian tissue, RHF downregulated the protein and mRNA expression of NLRP3, caspase\u20101, the N\u2010terminal fragment of gasdermin D (GSDMD\u2010NT), IL\u201018, and IL\u20101\u03b2, and lowered the mRNA levels of IL\u20106 and TNF\u2010\u03b1, thereby attenuating both systemic and local ovarian inflammatory responses. Taken together, these findings demonstrate that RHF confers protective effects in PCOS rats, which are associated with the amelioration of HPO axis function and suppression of inflammatory responses.\n                  <\/jats:p>","DOI":"10.1002\/fsn3.72004","type":"journal-article","created":{"date-parts":[[2026,6,8]],"date-time":"2026-06-08T04:36:31Z","timestamp":1780893391000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Total Flavonoids From\n                    <i>Rubus chingii<\/i>\n                    Hu on the Hypothalamic\u2013Pituitary\u2013Ovarian Axis and Inflammatory Response in Polycystic Ovary Syndrome Rats"],"prefix":"10.1002","volume":"14","author":[{"given":"Mengfan","family":"Peng","sequence":"first","affiliation":[{"name":"Faculty of Medicine, HuangHuai University  Zhumadian Henan China"},{"name":"Department of Pharmacy Zhumadian Traditional Chinese Medicine Hospital  Zhumadian Henan China"},{"name":"Key Laboratory of Cardiovascular and Cerebrovascular Diseases, Tianfang Pharmaceutical Co., Ltd.
