Polycystic ovarian syndrome （PCOS） is a common endocrine and metabolic disease mainly occurring among women of childbearing age. Its main symptoms include menstrual disorders， acne， hirsutism， infertility， oily skin， acanthosis nigricans， and obesity. Currently， the etiology and pathogenesis of PCOS remain unclear. Classical formulas， which have rigorous compatibility， concise composition， precise alignment with syndromes， and definitive therapeutic effects， demonstrate unique practical and scientific value in the treatment of PCOS. These formulas exhibit significant clinical efficacy， mild adverse effects， and sustained therapeutic outcomes. To explore the current status and mechanisms of classical formulas in treating PCOS， on the basis of Zhang Zhongjing's academic thoughts on gynecological diseases， this paper reviewed the relevant literature on the treatment of PCOS with classical formulas in recent years. The findings reveal that the pathogenesis of PCOS predominantly involves a combination of internal deficiency and superficial excess， closely related to dysfunction of the liver， spleen， and kidney. The root cause lies in deficiency， and on this basis， there are also symptoms of qi stagnation， blood stasis， phlegm obstruction， and dampness encumbrance. Commonly used classical formulas for treating this disease include Guizhi Fuling pills， Danggui Shaoyao powder， Wenjing decoction， and Jingui Shenqi pills. These classical formulas have good clinical efficacy in treating PCOS. Their mechanisms of action may be related to improving serum levels of sex hormones， increasing the dominant follicle diameter and endometrial thickness， alleviating insulin resistance， lowering glucose and lipid metabolism， inhibiting oxidative and inflammatory reactions in the ovarian tissue， regulating the intestinal flora， correcting the flora disorder， protecting the intestinal barrier function， and regulating the phosphatidylinositol 3-kinase/protein kinase B signaling pathway. The above research results can help doctors use classical formulas flexibly， broaden diagnostic and therapeutic approaches for PCOS and provide ideas for improving the traditional Chinese medicine diagnosis and treatment plan for PCOS.

OBJECTIVE To explore the clinical efficacy of the Yushen Yangluan Formula in treating diminished ovarian reserve(DOR)with kidney essence deficiency based on mitochondrial energy metabolism and oxidative stress.METHODS A total of 70 pa-tients diagnosed with DOR due to kidney essence deficiency,who visited the gynecology department of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine from September 2023 to June 2024,were selected.The patients were randomly divided into two groups according to the random number table method.The treatment group(35 cases)received the Yushen Yangluan Formula,while the control group(35 cases)received a Chinese herbal placebo,with treatment lasting for 3 months,and during the treatment pe-riod,one case dropped out from each group.Antral follicle count(AFC),traditional Chinese medicine(TCM)syndrome scores,and serum levels of anti-Mullerian hormone(AMH),follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),re-active oxygen species(ROS),and adenosine triphosphate(ATP)levels were compared between the two groups.RESULTS After treatment,the TCM syndrome scores for kidney deficiency in both groups decreased compared to before treatment(P<0.05,P<0.01),with the experimental group showing greater improvement than the control group(P<0.01).Following treatment,the FSH levels in the experimental group decreased compared to before treatment(P<0.05),while AMH levels increased(P<0.05),and the antral follicle count(AFC)also increased significantly(P<0.01),with the experimental group outperforming the control group(P<0.05,P<0.01).After treatment,serum ROS levels in the experimental group decreased(P<0.01),and ATP levels increased(P<0.01),with the experimental group showing superior results compared to the control group(P<0.01).CONCLUSION Yushen Yangluan Formu-la can improve the ovarian function and TCM syndrome score of patients with DOR of kidney essence deficiency type,which may be re-lated to improving mitochondrial energy metabolism and reducing oxidative stress.
