Objective: To evaluate the effects of Jianpi Bushen Huatan Recipe on sex hormone levels、 blood lipid and blood glucose levels in the treatment of obese poly-cystic ovarian syndrome(PCOS).Methods: Data bases including the CNKI、Vip 、Wanfang were searched.Studies about randomized controlled trials (RCT) of the effectiveness of Jianpi Bushen Huatan Recipe Combined with Metformin in the Treatment of obese PCOS were included.Rev Man 5.3 software was used for meta analysis. Results: A total of 11 studies were enrolled. Meta-analysis showed that Jianpi Bushen Huatan Recipe Combined with Metformin significantly improved the clinical total effective rate of patien ts(RR=1.32,95％CI(1.20,1.45),P <0.00001);reduced the body mass index(BMI)(SMD=-0.92,95％CI(-1.13,-0.72),P<0.00001),luteinizing hormone(LH)(SMD=-1.00,95％CI(-1.37,-0.62),P<0.00001),LH/FSH(SMD=-1.03,95％CI(-1.34, -0.71),P<0.00001),insulin resistant index(HOMA-IR)(SMD=-0.59,95％CI(-0.79,-0.40),P<0.00001),fasting insulin(FIN) (SMD=-0.77,95％CI(-1.19,-0.35),P=0.0003),total cholesterol (TC) (SMD=-0.63,95％CI(-0.88,-0.38),P<0.00001),triglycerides(TG) (SMD=-0.60,95％CI(-0.83,-0.36),P<0.00001),high-density lipoprotein(HDL)(SMD=-0.41,95％CI(-0.51,-0.32),P<0.00001).However, there was no statistically significant in waist-to-hip ratio(WHR),follicle stimulating hormone(FSH),fasting blood sugar(FBS)and low density lipoprotein(LDL). Conclusions: Jianpi Bushen Huatan Recipe Combined with Metformin in the treatment of obese PCOS has an advantage in improving the sex hormone level,blood lipid and blood glucose level,and is superior to metformin alone.
