摘要
Objective：To focus on the asthmatic pathogenesis and clinical manifestations related to epithelial sodium channel （ENaC）/chlorine ion channel.Data Sources：The data analyzed in this review were the English articles from 1980 to 2015 from journal databases,primarily PubMed and Google Scholar.The terms used in the literature search were：（1） ENaCs;cystic fibrosis （CF） transmembrane conductance regulator （CFTR）;asthma/asthmatic,（2） ENaC/sodium salt;CF;asthma/asthmatic,（3） CFTR/chlorine ion channels;asthma/asthmatic,（4） ENaC/sodium channel/scnn1a/scnn1b/scnn1g/scnn1d/amiloride-sensitive/amiloride-inhibtable sodium channels/sodium salt;asthma/asthmatic,lung/pulmonary/respiratory/tracheal/alveolar,and （5） CFTR;CF;asthma/asthmatic （ti）.Study Selection：These studies included randomized controlled trials or studies covering asthma pathogenesis and clinical manifestations related to ENaC/chlorine ion channels within the last 25 years （from 1990 to 2015）.The data involving chronic obstructive pulmonary disease and CF obtained from individual studies were also reviewed by the authors.Results：Airway surface liquid dehydration can cause airway inflammation and obstruction.ENaC and CFTR are closely related to the airway mucociliary clearance.Ion transporters may play a critical role in pathogenesis of asthmatic exacerbations.Conclusions：Ion channels have been the center of many studies aiming to understand asthmatic pathophysiological mechanisms or to identify therapeutic targets for better control of the disease.
