目的:观察热敏化腧穴埋线与舒利迭对慢性持续期支气管哮喘的疗效差异。方法:将60例符合纳入标准的患者按照随机数字表分为治疗组(热敏化腧穴埋线法)和对照组(舒利迭吸入剂,各30例)。热敏化腧穴埋线,每周治疗1次;舒利迭吸入剂,每次1吸,...目的:观察热敏化腧穴埋线与舒利迭对慢性持续期支气管哮喘的疗效差异。方法:将60例符合纳入标准的患者按照随机数字表分为治疗组(热敏化腧穴埋线法)和对照组(舒利迭吸入剂,各30例)。热敏化腧穴埋线,每周治疗1次;舒利迭吸入剂,每次1吸,每日两次。分别在治疗3个月后及治疗后3个月对两组的肺功能(FEV1、PEF)、哮喘控制问卷(Asthma Control Test,ACT)进行分析比较,进行临床疗效统计。结果:治疗3个月结束时,两组肺功能、ACT评分较前明显提高(均P<0.01),组间比较差异无统计学意义(P>0.05),表明两组疗法的近期疗效基本一致;治疗结束后3个月,热敏化腧穴埋线组肺功能、ACT评分维持治疗结束时水平,而舒利迭组下降明显,且热敏化腧穴埋线组总有效率为83.3%(25/30)明显优于舒利迭组的56.7%(17/30)(P<0.05),表明热敏化腧穴埋线法疗效更持久,远期疗效更佳。结论:热敏化腧穴埋线法能有效改善慢性持续期支气管哮喘患者肺功能及临床症状,其近期疗效与舒利迭基本一致,但远期疗效优于舒利迭。展开更多

Methods Sixty-four cases were randomly divided into an acupuncture and moxibustion group （n=32） and an acupuncture group （n=32）. Conventional acupuncture at Tiānshū （天枢 ST 14）, Zúsānlǐ （足三里 ST 36）, Gōngsūn （公孙 SP 4） and other acupoints was used in the two groups, and moxibustion on heat-sensitive acupoints was added in the acupuncture and moxibustion group. The treatment frequency was 5 times a week, and 4 weeks were a course. After 2 courses, the therapeutic effect was evaluated. Results The clinical symptom scores after treatment in two groups decreased obviously than those before treatment （both P〈0.01）. The cured and markedly effective rate in the acupuncture and moxibustion group was 87.5% （28/32）, and that in the acupuncture group was 37.5% （12/32）, so the effect in the acupuncture and moxibustion group was better than that in the acupuncture group （P〈0.01）. The improvement of all kinds of symptom scores in the acupuncture and moxibustion group was all better than that in the acupuncture group （all P〈0.05）. Conclusion The clinical effect of acupuncture combined with moxibustion on heat-sensitive acupoints on IBS-D is better than that of acupuncture.展开更多
