Menopausal Syndrome
Conditions
Brief summary
The primary object is to evaluate the efficacy and safety of electroacupuncture for symptoms of women during menopausal transition .
Detailed description
Menopause transition is called perimenopause in the past time. 40-80% women aged 40 to 65 have symptoms during this period. Hormone therapy is the recommended therapy for menopause and there is not enough evidence in favor of alternative medicine's effect. Our pilot trial showed that electroacupuncture had better effect for menopause transition symptoms than sham electroacupuncture. We are going to conduct a phase Ⅱ clinical trial to further evaluate the safety and effect of electroacupuncture for menopause transition symptoms.
Interventions
OTHERelectroacupuncture
Stick adhesive tapes to all points. For ST25, EX-CA1 and RN4, insert the needle vertically through the pads and the skin, and then slowly and vertically penetrate through the layer of fatty tissue, into the muscles of the abdominal wall .For RN4, manipulate the needle with an even lifting, thrusting and twisting method slightly for 3 times. Insert the needle vertically at SP6 to a depth of 1 cm. Manipulate the needle with an even lifting, thrusting and twisting method slightly for 3 times to reach de-qi. Put the electric stimulator on the pair of EX-CA1 and ST25 points with a dilatational wave, 10/50 Hz, 0.5-1.0mA. To turn on the current intensity till the abdomen shivers. The same manipulation methods for RN4 and SP6 will be given every 10 minutes (3 times in all).
OTHERsham electroacupuncture
Non-points proximate to RN4 (P1), EX-CA1(P2)，ST25 (P3) and SP6 (P4) (double sides) are used.P1 and P3 are at the sites 1 cm (outward in horizontal direction) proximate to RN4 and ST25 respectively. P2 is 2 cm (outward in horizontal direction) proximate to EX-CA1. P4 is at the middle site of the spleen meridian and the kidney meridian (backward in horizontal direction proximate to SP6). Stick adhesive tapes to all points. Blunt needles will be used to be inserted to but not piercing the skin. Even lifting, thrusting and twisting manipulation methods will be given for each non-point for 3 times. Put the sham electric stimulator on the pair of P2 and P3 with the same parameters as the acupuncture group. But there is no current intensity actually.

| Change From Baseline in Menopause Rating Scale Total Score | at baseline and week 8 | The change in menopause rating scale (MRS) total score compared with baseline at week 8 equals MRS total score at week 8 minus MRS total score at baseline. MRS is a self-report questionnaire for evaluating the severity of menopausal symptoms in women, which contains 11 items. Each of the 11 symptoms contained a scoring scale from 0 (no complaints) to 4 (very severe symptoms). The total score will be calculated as the all items ranging from 0 to 44, with higher scores indicating worse symptoms.

Change From Baseline in the Physical Domain of Menopause-Specific Quality of Life Questionnaire
The change from baseline in the physical domain of Menopause-Specific Quality of Life Questionnaire (MENQOL) at weeks 4, 8, 20 and 32 equals the physical domain of MENQOL at weeks 4, 8, 20 and 32 minus the physical domain of MENQOL at baseline, respectively. The physical domain contains 16 items (items 11-26). Each of the item scores ranges from 0 to 6. The vasomotor domain score will be calculated as the all physical items ranging from 0 to 96, with lower scores indicating a better quality of life.
