Abstract:

Objective To observe the clinical efficacy of Sini powder combined with Guizhi Gancao Longgu Muli decoction in the treatment of polycystic ovary syndrome (PCOS) accompanied by circadian rhythm disorder. Methods A total of 102 patients diagnosed with PCOS and comorbid circadian rhythm disorder, who received treatment at Shanxi Bethune Hospital from March 2023 to March 2025, were randomly assigned to either an observation group or a control group using a random number table, with 51 cases in each group. The control group received Diane-35 along with lifestyle intervention, whereas the observation group was additionally treated with modified Sini powder combined with Guizhi Gancao Longgu Muli decoction. Both groups underwent treatment for three consecutive menstrual cycles. The clinical efficacy was compared between the two groups. Moreover, changes in traditional Chinese medicine syndrome scores, endocrine hormones, glucose and lipid metabolism indices, sleep quality, and circadian rhythm indicators were evaluated both before and after the treatment. Adverse reactions were also documented. Results The total effective rate in the observation group (96.08%) was significantly higher than that in the control group (80.39%) (P < 0.05). After treatment, the observation group showed lower scores of Traditional Chinese Medicine (TCM) syndromes, luteinizing hormone (LH), LH/follicle-stimulating hormone (FSH) ratio, testosterone (T), anti-Müllerian hormone (AMH), fasting blood glucose (FBG), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR), triglyceride (TG), total cholesterol (TC), cortisol (COR), and Pittsburgh Sleep Quality Index (PSQI) scores compared to the control group (P < 0.05). In contrast, the levels of follicle-stimulating hormone (FSH) and melatonin (MT) were higher in the observation group than in the control group (P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the observation group (3.92%) and the control group (5.88%) (P > 0.05). Conclusion Sini powder combined with Guizhi Gancao Longgu Muli decoction can effectively regulate sex hormone disorders, improve insulin resistance and abnormal lipid metabolism, and restore the normal sleep-wake rhythm.
