目的观察通肺络补宗气方在提高特发性肺间质纤维化患者活动耐力方面的疗效及安全性。方法将50例此类患者随机分为两组,观察组25例,对照组25例,对照组采用大剂量N-乙酰半胱氨酸治疗,观察组在此基础上加服通肺络补宗气方,疗程3个月。结果在6分钟步行距离、圣·乔治呼吸问卷、呼吸困难及咳嗽症状方面,观察组均优于对照组(P<0.05),肺功能两组之间比较无统计学意义,且两组患者均无严重不良事件出现。结论通肺络补宗气方能明显提高患者的活动耐力、改善患者生活质量及稳定肺功能,并且能够减轻患者呼吸困难及咳嗽症状。

Objective To investigate the effect of Tongfeiluo Buzongqi prescription on activity endurance of patients with Idiopathic Pulmonary Fibrosis（ IPF） and evaluate its safety. Methods 50 patients with IPF were randomly divided into two groups. The control group was treated with large dosage of N-Acetyl-L-cysteine,while the treatment group was treated with Tongfeiluo Buzongqi prescription plus large dosage of N-Acetyl-L-cysteine. The treatment period is three months. Results The treatment group was better efficacy than control group in the 6-minute walk distances,St. George’s Respiratory Questionnaire,dyspnoea score and cough score（ P 〈 0. 05）. There was no statistical significance between the two groups of lung function,and there were no serious adverse events in the two groups. Conclusion Tongleiluo Buzongqi prescription can significantly improve the activity endurance and quality of life of patients,can stabilize lung function and alleviate symptoms of dyspnea and cough.
