[Mild and moderate postpartum depression treated with acupuncture of Tiaoren Tongdu: a real world study].

OBJECTIVE To observe the clinical therapeutic effect on mild and moderate postpartum depression treated with acupuncture of Tiaoren Tongdu (regulating the conception vessel and unblocking the governor vessel) on the base of real world. METHODS A total of 116 patients with mild and moderate postpartum depression were divided into an acupuncture group (103 cases) and a non-acupuncture group (13 cases) according to treatment regimen provided. In the acupuncture group, acupuncture of Tiaoren Tongdu was applied to Baihui (GV 20), Yintang (GV 29), Zhongwan (CV 12), Qihai (CV 6), Guanyuan (CV 4), Neiguan (PC 6), Shenmen (HT 7), Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Needles were retained for 30 min each time, the treatment was given once every other day, 3 times a week. In the non-acupuncture group, psychotherapy was provided, once daily. The duration of treatment in the two groups was 8 weeks. According to the treatment times of acupuncture, the acupuncture group was subdivided into an acupuncture A group (60 cases with total treatments ≥ 6 times) and an acupuncture B group (43 cases with total treatments<6 times). Using propensity score matching method, the patients of the acupuncture A and B groups were matched each other. Finally, 31 pairs of cases were matched successfully. Before treatment, at 1st, 2nd, 4th and 8th weeks of treatment, as well as at 3-month follow-up, the scores of Hamilton depression scale (HAMD) were compared in patients among the three groups. Using Logistic regression, the impact of acupuncture frequencies on the therapeutic effect was analyzed and the clinical therapeutic effect was assessed. RESULTS The total effective rate of the acupuncture A group was 100.0% (31/31), better than 76.9% (10/13) in the non-acupuncture group and 58.1% in the acupuncture B group (18/31) (P<0.05). HAMD score at each time point after treatment was lower than that before treatment in the patients of each group (P<0.05). But HAMD score at each time point after treatment in either the acupuncture A group or the acupuncture B group was lower than that in the non-acupuncture group separately (P<0.05), HAMD scores in the acupuncture A group at the 4th and 8th weeks of treatment and at follow-up were lower than those in the acupuncture B group (P<0.05). Logistic regression analysis showed that the total times of acupuncture treatment and the persistent days of treatment had a certain relation to therapeutic effect (P<0.05). CONCLUSION Acupuncture of Tiaoren Tongdu effectively improves in mild and moderate postpartum depression and its therapeutic effect is closely related to treatment course.
