摘要(Abstract)：

目的:分析慢性阻塞性肺疾病(COPD)合并支气管扩张试验阳性患者小气道通气功能指标,为探讨该病的发病提供依据。方法:住院治疗达到稳定期的单纯COPD患者70例(单纯COPD组),支气管扩张试验阳性COPD患者39例(扩张试验阳性组),比较两组患者性别比例、年龄、体重指数(BMI)及使用沙丁胺醇支气管舒张试验前后第1秒用力呼气量占预计值百分比(FEV 1%)、1秒率(FEV/FVC%)、最大呼气中期流量(MMEF)、50%肺活量时的最大呼气流速(FEF 50%)、25%肺活量时的最大呼气流速(FEF 25%)肺功能指标。结果:扩张试验阳性组年龄<单纯COPD组(P<0.05),吸入沙丁胺醇前扩张实验阳性COPD组MMEF、FEF50%、FEF 25%较单纯COPD组低(P<0.05);吸入沙丁胺醇后这些指标和单纯COPD组比较,差异无统计学意义(P>0.05)。结论:支气管扩张试验阳性的COPD患者发病年龄相对较小,小气道功能较单纯COPD低。
Objective: To investigate small airway function index in COPD patients with positive bronchial dilation test,in order to provide clinical data for better understanding the pathogenesis of this disease. Method: Seventy COPD patients in stable stage( single COPD group) and 39 COPD patients with positive bronchial dilation test( dilation positive group) were chosen. Sex ratio,age and BMI in both groups were analyzed. Comparing lung function indexes of FEV1%,FEV / FVC%,MMEF,FEF50% and FEF 25% before and after salbutamol bronchial dilation test. Results: The age of dilation positive group was younger than single COPD group( P < 0. 05),MMEF,FEF50% and FEF25%were lower in dilation positive group than single COPD group before inhalation of salbutamol( P < 0.05) while no difference was found in these indexes between the two growps after inhalation of salbutamol( P > 0. 05). Conclusions: COPD patients with positive bronchial dilation test are younger,their small airway function is worse than COPD group.
