气道炎症反应是哮喘的一个重要病理生理特征,这在成人哮喘患者中已有大量研究证实。但在儿童中因取材不便而受到限制。作者在急性哮喘患儿采用吸入生理盐水诱导痰液的方法,并分析哮喘急性发作期和缓解期痰液细胞计数的变化来评价气道炎症状态。
Airway inflammation is an important pathophysiological feature of asthma, which has been confirmed in a large number of studies in adults with asthma. But is limited in children due to inconvenience. The authors used airway aspiration induced sputum in children with acute asthma and evaluated the change of sputum cell count during acute exacerbation and remission of asthma to evaluate the status of airway inflammation.
