[Abstract]
Objective To observe the clinical efficacy of modified Cangfu Daotan Decoction in treating polycystic ovary syndrome with insulin resistance(PCOS-IR) of phlegm-damp type,and its effects on chronic low-grade inflammation, gut microbiota,and microbial metabolites. Methods A total of 104 patients were randomly divided into an observation group and a control group,with 52 cases in each group. The control group received oral Metformin Tablets (0.5 g twice daily), while the observation group was treated with modified Cangfu Daotan Decoction (one dose daily) . The treatment course lasted for 3 menstrual cycles. (1) Primary efficacy endpoint:Ovulation rates of both groups were monitored. (2) Secondary efficacy endpoints: ① Fasting insulin (FINS), fasting blood glucose (FBG), and homeostatic model assessment of insulin resistance (HOMA-IR) were measured;② ovarian volume was calculated via color Doppler ultrasound; ③ menstrual irregularity scores and phlegm-damp syndrome scores were assessed. (3) Additional endpoints: ① Serum levels of interleukin-6 (IL-6), interleukin-18 (IL-18), tumor necrosis factor-α(TNF-α),and C-reactive protein(CRP) were measured by enzyme-linked immunosorbent assay (ELISA); ② gut microbiota analysis;③ short-chain fatty acids (SCFAs) analysis;④ bile acid (BA) profiling,including cholic acid (CA), deoxycholic acid (DCA), glycocholic acid (GCA), glycodeoxycholic acid (GDCA), taurocholic acid (TCA) , tauroursodeoxycholic acid (TUDCA) , chenodeoxycholic acid (CDCA) , and glycochenodeoxycholic acid (GCDCA). Results (1) The ovulation rates in the observation group were significantly higher than those in the control group during the second and the third menstrual cycles post-treatment (P<0.05) . (2) After treatment,FINS,FBG,and HOMA-IR were significantly decreased in both groups (P<0.05),with the observation group showing lower FINS and HOMA-IR than the control group (P<0.05);bilateral ovarian volume, menstrual irregularity scores,and phlegm-damp syndrome scores decreased significantly in both groups (P<0.05), while the observation group exhibited smaller ovarian volume and lower symptom scores than the control group (P< 0.05) . (3) Post-treatment serum IL-6, IL-18, TNF- α, and CRP levels were significantly decreased in both groups (P<0.05),with the observation group showing lower levels than the control group (P<0.05). Gut microbiota abundance and Shannon-Wiener index were significantly increased (P<0.05), Lactobacillus and Bifidobacterium colonies increased (P<0.05),Enterobacteriaceae and Bacteroides colonies decreased (P<0.05),but microbiota evenness remained unchanged (P>0.05); the observation group had higher gut microbiota abundance, ShannonWiener index, and Lactobacillus/Bifidobacterium counts than the control group (P<0.05) , with lower Enterobacteriaceae and Bacteroides counts (P<0.05). SCFAs, GDCA, TUDCA, and CDCA levels significantly increased (P<0.05),while CA,DCA,GCA,TCA,and GCDCA levels decreased (P<0.05);the observation group showed higher SCFAs,GDCA,TUDCA,and CDCA levels and lower CA,DCA,GCA,TCA,and GCDCA levels than the control group (P<0.05). Conclusion Modified Cangfu Daotan Decoction alleviates PCOS-IR with phlegm-damp syndrome by modulating the gut microbiota-microbial metabolites-chronic inflammation axis,improving glucose metabolism,reducing insulin resistance,restoring menstruation,and promoting ovulation. Its clinical efficacy surpasses Metformin with better safety.
