隔姜灸子宫穴治疗原发性痛经的临床疗效观察（英文）

Objective： To investigate the clinical effect of ginger-partitioned moxibustion at Zigong（EX-CA 1） for primary dysmenorrhea. Methods： A total of 112 patients with primary dysmenorrhea were randomized into an observation group and a control group according to their visiting sequence, 56 cases in each group. Patients in the observation group received ginger-partitioned moxibustion at Zigong（EX-CA 1）, while patients in the control group received oral intake of analgesic. For both groups, treatment started 1 week before menstruation and lasted for 3 menstrual cycles, continued by a 3-month follow-up visit, then the clinical efficacy was evaluated. Results： By the end of treatment, symptom score in the observation group was lower than that in the control group, showing a statistical significance（P〈0.05）. After 3 months of treatment, the value of prostaglandin F2 a（PGF2α）, systolic-to-diastolic peak velocity ratio（S/D）, resistance index（RI） and pulsatility index（PI） in the observation group were significantly higher than those in the control group, showing statistical significances（all P〈0.01）.The recovery rate in the observation group was higher than that in the control group, showing a statistical significance（P〈0.05）. Conclusion： Ginger-partitioned moxibustion at Zigong（EX-CA 1） for primary dysmenorrhea is a combination of the merits of warming function of moxibustion, dissipating function of ginger and stimulation of acupoint, and is better than oral intake of analgesic.

目的:观察隔姜灸子宫穴对原发性痛经的止痛效果。方法:将符合纳入标准的112例原发性痛经患者按照入院的先后顺序随机分成观察组和对照组,每组56例。观察组接受隔姜灸子宫穴,对照组口服常规止痛药,两组均在经前1星期开始干预,共治疗3个月经周期,并随访3个月,比较两组患者的临床疗效。结果:治疗结束时,观察组患者症状积分低于对照组,组间差异有统计学意义(P<0.05)。治疗3月后,观察组患者的前列腺素F2a(PGF2α)水平及子宫动脉血流的收缩期峰流速与舒张期峰流速比(S/D)、阻力指数(RI)及搏动指数(PI)的值均优于对照组,组间差异均有统计学意义(均P<0.01)。观察组治愈率高于对照组,组间差异有统计学意义(P<0.05)。结论:隔姜灸子宫穴治疗原发性痛经,发挥了艾灸的温通、生姜的温散、腧穴的刺激等综合作用,疗效优于口服止痛药物。
