Clinical efficacy of acupuncture combined with modified Xiangfu Decoction in treatment of menopausal insomnia cause by liver Qi stagnation

Abstract

To evaluate the efficacy and safety of acupuncture combined with modified Xiangfu Decoction in the treatment of menopausal insomnia case by liver Qi stagnation. Totally 120 cases were randomly divided into the control group(60 cases) and the treatment group(60 cases). Estazolam and acupuncture combined with modified Xiangfu Decoction were given for 16 weeks. Before and after treatment, Epworth sleepiness scale(ESS), Pittsburgh sleep quality index(PSQI), Hamilton anxiety scale(HAMA) and traditional Chinese medicine(TCM) syndrome score were compared between the two groups. Polysomnography monitor was used to monitor sleep progress and sleep structure. Serum LH, FSH and E_2 were determined. The clinical efficacy and incidence of adverse reactions were observed. Four cases were lost during the study. The total effective rate in the treatment group was 91.5%, which was higher than that in the control group 75.4%(P<0.05). After treatment, the scores of clinical symptoms(ESS, PSQI, HAMA, TCM symptoms) in the treatment group were significantly reduced(P<0.05), and lower than that in the control group(P<0.05). TST, SE in the treatment group were increased(P<0.05), while AWT, SL, AT in the treatment group were decreased(P<0.05), and the improvement was more significant than that in the control group(P<0.05). S_1 in the treatment group was decreased(P<0.05), whereas S_2, S_(3+4), REM in the treatment group were increased(P<0.05), and the improvement was more significant than that in the control group(P<0.05). The contents of LH and FSH in the treatment group were significantly reduced(P<0.05), while the content of E_2 was significantly increased(P<0.05), and the changes were more significant than those in the control group(P<0.05). The incidence of adverse reactions in the control group was 8.8%, which was higher than 1.7% in the treatment group(P<0.05). Acupuncture combined with modified Xiangfu Decoction could significantly improve the sleep status of menopausal insomnia cases caused by liver Qi stagnation, with a lower incidence of adverse reactions, and so is worthy of clinical promotion and application.
