Abstract: Cough-variant asthma(CVA) is a common and frequently occurring respiratory disease in children.In recent years,with the aggravation of air pollution,the change in living habits and the increase in social pressure,the number of CVA cases in children is increasing year by year,which has a great impact on the physical and mental development of children and their social activities.Modern medicine is effective in treating CVA,but the treatment course is long and the compliance of children is low,which significantly increases the side effects.Traditional Chinese medicine treatment has the obvious advantages of definite curative effect and few side effects.Professor Qin Yanhong believes that the occurrence of CVA is the result of internal and external causes:the external evil is dominated by wind evil,and the internal cause is often the deficiency of lung and spleen in children.The key pathogenesis is the internal accumulation of wind sputum and the upward reversal of lung qi,and the pathological factors are mainly wind,sputum and qi,so the treatment emphasizes on dispersing wind,eliminating phlegm and regulating qi,and the self-designed "Zhike decoction" with modification is used to treat the disease.Due to the long course of CVA disease,and because the pathological focus of different periods is different,the treatment by stage is emphasized in clinical practice,the main treatment is to remove the evil during the attack period and to reinforce the deficiency and remove the evil during the recovery period.The effect is significant,and it is well recognized by parents.
