中文摘要：

目的：观察针药结合治疗血虚风燥型慢性荨麻疹的临床效果,并与单纯口服消风散进行疗效比较。方法：将89例血虚风燥型慢性荨麻疹患者随机分为2组,治疗组45例,对照组44例,治疗组以刺络放血疗法联合内服消风散加减方治疗,对照组单纯口服消风散加减方治疗,疗程均为4周,比较2组患者的临床疗效及复发率。结果：治疗后2组患者瘙痒、风团、心烦易怒、不易入睡等症状缓解,综合疗效治疗组均优于对照组,差异有统计学意义（P〈0.01,P〈0.05）。2个月内的复发率治疗组（37.50%）与对照组（53.85%）比较差异无统计学意义。结论：刺络放血疗法联合消风散治疗血虚风燥型慢性荨麻疹疗效确切,且优于单纯的口服消风散疗效,在防止复发方面二者差异不明显。

英文摘要：

Objective： To observe the clinical efficacy of combination of blood-letting therapy and Xiaofeng Powder in treating chronic urticaria（CU） with syndrome of wind and dryness due to blood deficiency, and compare the efficacy with that of Xiaofeng Powder alone. Methods： Eighty-nine CU patients with syndrome of wind and dryness due to blood deficiency were randomly divided into two groups, 45 patients in treatment group were treated with combination of blood-letting therapy and modified Xiaofeng Powder, and 44 patients in control group were treated with modified Xiaofeng Powder. After treating for 4 weeks, the clinical curative efficacy and recurrence rate of patients in the two groups were evaluated and compared. Results： After treatment, the comprehensive curative effect and remission of symptoms including pruritis, wheals, dysphoria, difficulty in falling asleep and so on, were superior to those of control group, and the difference between the two groups was statistically significant（P〈0.01, P〈0.05）. There was no significant difference in recurrence rate between treatment group（37.50%） and control group（53.85%） within 2 months. Conclusion： The curative effect of combination of blood-letting therapy and Xiaofeng Powder in treating CU with syndrome of wind and dryness due to blood deficiency is accurate, which is superior to that of Xiaofeng Powder alone, and yet there is no significant difference in preventing recurrence between the two therapies.
