摘　　要：咳嗽是机体的自我防御机制,临床以咳嗽为唯一症状或主要症状、时间超过8周、胸部X线检查无明显异常者为不明原因的慢性咳嗽。引起慢性咳嗽的病因有多种,虽然机制还尚不清楚,但是大多数病人存在咳嗽反射过敏和敏感性增加,可能与呼吸道感染等因素导致感觉神经阈值降低有关。咳嗽一症可单独存在,也可合并存在。Cough is the defense mechanism of organism. In clinic,chronic cough has been defined as a cough lasting more than 8 weeks and having no obvious abnormality in chest X-ray examination. There are many kinds of causes of chronic cough though the chronic cough mechanism is not very clear,most of the patients have allergic cough reflex and increased sensibility,it may be related to the decrease of sensory nerve threshold caused by factors such as respiratory tract infection. Cough can exist alone or in combination as well.
