目的评价清肺润燥汤治疗风燥伤肺型感冒后咳嗽的临床疗效。方法将60例感冒后咳嗽风燥伤肺型患者随机分为治疗组和对照组各30例。治疗组给予清肺润燥汤,每日1剂,分早晚2次口服;对照组给予克咳胶囊,每次0.9g,每日2次口服。两组均治疗7天后观察中医证候疗效及咳嗽症状起效时间、消失时间,并于治疗前后记录咳嗽频度及程度、咯痰、咽痒等中医症状评分。结果治疗组治疗前后中医症状积分分别为(16.90±3.53)分、(9.00±2.77)分,对照组分别为(17.60±3.57)分、(11.37±3.49)分。两组患者治疗后中医症状积分较治疗前明显降低(P<0.05),治疗组降低程度优于对照组(P<0.05)。治疗组咳嗽症状的起效时间、消失时间均明显短于对照组,差异均有统计学意义(P<0.05)。治疗组中医证候疗效总有效率为86.7%,对照组76.7%,差异有统计学意义(P<0.05)。结论清肺润燥汤能有效改善感冒后咳嗽风燥伤肺型患者的中医症状,临床疗效确切。

Objective To evaluate the therapeutic effect of Qingfei Runzao Decoction （Lung-Clearing Dryness-Moistening Decoction） for postinfectious cough. Methods Sixty cases of postinfectious cough were randomized into the treatment group and control group, with 30 in each. The treatment group was given Qingfei Runzao Decoction one dose daily. The control group was given Keke Capsule （capsule for cough） 0.9g once and twice daily. The treatment lasted for 7 days. The TCM pattern efficacy, the onset time and disappearing time of cough were observed after treatment. The TCM symptom scores of cough frequency, expectoration and throat itching and total scores were recorded before and after treatment. Results The total scores of TCM symptoms before and after treatment were （16. 90 ± 3. 53） and （9. 00 ± 2. 77） in the treatment group and （17.60±3.57） and （11.37±3.49） in the control group. The total scores of TCM symptoms were significantly improved in both groups after treatment （P〈0.05）, especially in the treatment group （P〈0.05）. The onset time and disappearing time of cough in the treatment group were significantly shorter than those in the control group （P（0.05）. The TCM pattern efficacy in treatment group and control group was 86.7% and 76.7% respectively, with a significant difference between groups （P〈 0.05）. Conclusion Qingfei Runzao Decoction is effective for postinfectious cough and it can obviously relieve the TCM symptoms.
