[Therapeutic efficacy of modified zigui decoction in treatment of polycystic ovary syndrome of gan-shen yin deficiency syndrome]

Abstract

Objective: To study the therapeutic efficacy of Modified Zigui Decoction (MZD) in treatment of polycystic ovary syndrome of Gan-Shen yin deficiency syndrome.

Methods: 66 polycystic ovary syndrome patients of Gan-Shen yin deficiency syndrome were randomly assigned to the MZD group (Group A) and the Westem medicine group (Group B), 33 patients in each. Patients in Group A orally took MZD, while those in Group B orally took Diane-35. Their menstrual cycle rate, basal body temperature (BBT), the ovarian size, the number of follicles, and changes of endocrine hormones were observed before treatment, the first menstrual cycle, and the sixth menstrual cycle after treatment.

Results: (1) The normal rate of one menstrual cycle after stopping taking medicine was 57.58% in Group A and 63.64% in Group B. There was no statistical difference between the two groups (P>0.05). The normal rate of six menstrual cycles after stopping taking medicine was 45. 45% in Group A and 21.21% in Group B. The former was superior to the latter, showing statistical difference (P<0.05). (2) The biphasic BBT rates of one menstrual cycle after stopping taking medicine were somewhat elevated in the two groups, better than before treatment respectively (P<0.01). But there was no statistical difference between the two groups (P>0.05). The biphasic BBT rate of six menstrual cycles after stopping taking medicine was 45.45% in Group A and 18.18% in Group B. The former was superior to the latter, showing statistical difference (P<0.05). (3) The bilateral ovarian volume of one menstrual cycle after stopping taking medicine was obviously reduced in both groups (P<0.01). The bilateral ovarian volume of six menstrual cycles after stopping taking medicine was still more reduced than before treatment in Group A (P<0.01), while it returned to the size of before treatment in Group B (P>0.05). (4) The number of follicles of one menstrual cycle after stopping taking medicine was obviously reduced in both groups (P<0.01). The number of follicles of six menstrual cycles after stopping taking medicine was still reduced in Group A (P<0.01), while it returned to the number before treatment in Group B (P>0.05). (5) The luteinizing hormone (LH), testosterone (T), LH/FSH ratio of one menstrual cycle after stopping taking medicine were obviously reduced in both groups (P<0.01). They were still more reduced six menstrual cycles after stopping taking medicine than before treatment in Group A (P<0.01), while they returned to the levels of before treatment in Group B (P>0.05).

Conclusions: MZD could effectively treat patients with polycystic ovary syndrome of Gan-Shen yin deficiency syndrome. Besides, its long-term efficacy was more stable and lasting.
