To observe the clinical effect of Bushen Huoluo decoction combined with Diane-35 in the treatment of polycystic ovarian syndrome with kidney deficiency and blood stasis syndrome.Methods:Seventy-eight patients diagnosed with polycystic ovarian syndrome were randomly divided into the treatment group and the control group.Those in the treatment group were treated by Bushen Huoluo decoction combined with Diane-35.Those in the control group were treated by Diane-35.Both groups were treated for 3 cycles.The serum sex hormones levels ［follicle-stimulating hormone (FSH),luteinizing hormone(LH),Testosterone(T),LH/FSH］ and the mean ovarian volume(MOV),mean follicle number(MFN)were compared between the two groups before treatment,after 3 cyclic treatment and at the 3th cycle after treatment.Results:The levels of relevant hormones and the indexes of B-ultrasonic were obviously improved after treatment in the two groups.However,3 cycles after treatment，these changes restored to the baseline as those before treatment in the control group,while maintained in the treatment group.Conclusion:Bushen Huoluo decoction combined with Diane-35 in treating polycystic ovarian syndrome not only shows marked short-term effect but also consolidate the curative effect.It is worth further research and promotion.
