• Lead Sponsor: Dongzhimen Hospital, Beijing

Brief Summary

The investigators plan to conduct the randomized controlled trial to evaluate the effectiveness of electro-press needle (EPN), a novel acupuncture needle combining shallow and gentle insertion with transdermal electrical stimulation, on menopause-associated hot flash in comparison with gamma-oryzanol group among women during menopausal transition and postmenopausal periods.

Detailed Description

As the most common type of menopause-associated symptoms, hot flashes affect up to 85% of women aging between 40 and 65 years . In China, women suffer from hot flushes as long as 4 to 5 years on average, some of whom may bear the symptoms for 12 years.Hormone replacement therapy (HRT) is generally recommended to relieve menopause-associated hot flashes.However, long-term usage of HRT may increase the incidence of endometrial, breast and ovarian cancer, thrombosis and strokes.Results of previous studies indicated that acupuncture might help to relieve the symptoms.There is insufficient evidence supporting its effectiveness for relieving the hot flash symptom.

Arm && Interventions

Group	Intervention	Description
Electro Press Needle	Electro Press Needle	Body acupoints of Yintang (GV29), Dazhui (GV14), Guanyuan (CV4), bilateral Zigong (EX-CA1), and bilateral Sanyinjiao (SP6) and auricular acupoints of Heart (CO15), Chuiqian (LO4) and Shenmen (TF4) will be selected for treatment. Auricular acupoints on right and left ear will be stimulated alternatively, one side on each time.The treatment will last 40mins for each session, 3 sessions a week (ideally every other day) for a succession of 6 weeks.
Gamma-Oryzanol	Gamma-Oryzanol	The patients in this group were given 10mgx100 tablets/bottle of gamma-oryzanol tablets (Tianjin Lishen Pharmaceutical), 20mg each time, three times a day, for 6 months.

Primary Outcome Measures

Name	Time	Method
The proportion of patients with a reduction of 50% or more on the mean 24-hour HF score from baseline	week 6	The mean 24-hour HF score = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/Number of days reported.

Secondary Outcome Measures

Name	Time	Method
The proportion of patients with at least a 50% reduction in the mean 24-hour HF severity from baselineHF frequency from baseline24-hour HF score from baseline	week 3,6,18,30	The mean 24-hour HF severity = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/ Number of HF reported.
The proportion of participants with a reduction of 50% or more on the mean 24-hour HF score from baseline	week 3,18,30	The mean 24-hour HF score = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/Number of days reported.
The proportion of participants with a reduction of 50% or more in the mean 24-hour HF frequency from baseline24-hour HF score from baseline	week 3,6,18,30	The mean 24-hour HF frequency = total number of HF reported/Number of days reported.
The change of Menopause rating scale (MRS) score from baseline	week 6,18 and 30	MRS is a common menopause specific subscale, including 11 items from psychological, somatic to urogenital, with 5 as minimal clinically important differences(MCID).
The change of Menopause-Specific Quality of Life Questionnaire (MENQOL) score from baseline	week 6,18 and 30	MENQOL consists of 29 items assessing four domains: VMS, physical symptoms, psychological symptoms, and urogenital/sexual symptoms,with 4 as minimal clinically important differences(MCID).
The changes in the mean 24-h HF score from baseline	week 3,6,18,30	The mean 24-hour HF score = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/Number of days reported.
Time domain analysis of 24-hour heart rate variability(HRV)	week 6,30	The indexes included total autonomic energy (SDNN) and sympathetic sensation Nerve tone (SDANN) and vagal tone (rMSSD)
Frequency domain analysis of 24-hour heart rate variability(HRV)	week 6,30	the indexes included total power spectrum (TP) reflecting the total energy of autonomic nerve, The low frequency power (LF, 0.04\~0.15Hz) reflects the sympathetic nerve activity and the high vagus nerve activity.Frequency power (HF, 0.15\~0.4Hz), LF/HF reflecting the balance between sympathetic and vagal tension.
The proportion of participants reporting "significantly reduced" or "moderately reduced" based on Global Response Assessment (GRA)	week 3,6,18,30	The response of participants to the treatments are divided into seven grades by GRA: significantly reduced, moderately reduced, slightly reduced, no change, slightly aggravated, moderately aggravated and significantly aggravated. The proportion of participants reporting "significantly reduced" or "moderately reduced" are recorded as the response rate of the overall efficacy.
