吸烟是慢性阻塞性肺疾病（ＣＯＰＤ）的一个高危诱因，外周气道炎症可致气道狭窄、气流受限，对此，本文研究了具有吸烟史的ＣＯＰＤ患者外周气道的炎症特征。作者收集了因患周围性肺癌而行肺部分切除术的１６例吸烟患者的外周气道标本，其中９例有慢性支气管炎和慢性气道受限 Smoking is a high-risk inducer of chronic obstructive pulmonary disease (COPD). Peripheral airway inflammation can cause airway narrowing and airflow limitation. In this paper, we studied the inflammatory features of the peripheral airway in COPD patients with a history of smoking. The authors collected peripheral airway samples from 16 smokers who underwent partial pneumonectomy for peripheral lung cancer, of whom 9 had chronic bronchitis and chronic airway restriction
