[Comparison between manual acupuncture and electroacupuncture for hot flashes and sex hormone of perimenopausal syndrome].

Objective: To compare the effect and differences sex the influence of hormone levels of perimenopau-sal syndrome patients between manual acupuncture and electroacupuncture (EA).

Methods: A total of 50 cases with perimenopausal syndrome were randomly assigned into an manual acupuncture group (27 cases) and an EA group (23 cases), and 1 case dropped in the EA group. The acupoints in the two groups were Guanyuan (CV 4), Zigong (EX-CA 1), Tianshu (ST 25), and Sanyinjiao (SP 6). Acupuncture with 3-time small and even manipulation of lifting, thrusting and twirling was used in the acupuncture group, once 10 min. EA with sparse-dense wave and 10 Hz/50 Hz was applied in the EA group for 30 min. The treatments in the two groups were for continuous 8 weeks (24 times in total), once the other day, 3 times a week. The scores of 24-hour hot flashes even, menopausal rating scale (MRS) and menopause-specific quality of life questionnaire (MENQOL) were recorded before treatment and after 4-week and 8-week treatment, as well as 12 and 24 weeks after treatment. Serum sex hormone levels were tested before and after 8-week treatment as well as 12 weeks after treatment, including serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estracliol (E).

Results: Compared with those before treatment, the 24-hour hot flashes even score, MRS and MENQOL scores were significantly lower after 4-week and 8-week treatments, 12 and 24 weeks after treatment (all <0.05). All the above scores after 8-week treatment were lower than those after 4-week treatment (all <0.05); and the scores 12 and 24 weeks after treatment were lower than those after 4-week and 8-week treatments (all <0.05); all the scores after treatment were not significantly different at any time between the two groups (all >0.05). Compared with those before treatment, serum FSH and E apparently improved in the two groups after 8-week treatment and 12 weeks after treatment (all <0.05). LH levels did not significantly change in the two groups (all >0.05). All the serum sex hormone levels showed no significant difference between the two groups (all >0.05).

Conclusions: Both acupuncture and EA can improve perimenopausal symptoms and serum sex hormone. The effects are similar.
