Abstract: Pneumonia with dyspneic cough is one of the common pulmonary diseases in pediatrics,which is equivalent to pediatric pneumonia in western medicine.At present,western medicine focuses on anti-pathogenic and symptomatic support treatment,but with the continuous increase and variation of pathogens,antibiotic resistance is gradually increasing,and the toxic side effects caused by antibiotics are also worrying.The use of traditional Chinese medicine in the treatment of children with pneumonia with dyspneic cough is gaining increasing acknowledgement and favor,so it is particularly important to explore more and effective methods and means to treat pneumonia with dyspneic cough in children.Pneumonia with dyspneic cough in children is closely related to Xuanfu theory.Xuanfu is tiny and spreads all over the lungs,which is an important part of lung tissue,and the lung functions through Xuanfu.The opening of Xuanfu means the normal condition,and the closing of Xuanfu means the abnormal condition.The microscopic nature of pneumonia with dyspneic cough is the lesion of Xuanfu.Based on the Xuanfu theory and clinical experience,this paper discusses the correlation between Xuanfu theory and pneumonia with dyspneic cough in children.It points out that the closing of Xuanfu is the basic pathogenesis of pediatric pneumonia with dyspneic cough,and the basic principle of treatment for pediatric pneumonia with dyspneic cough should be the opening of Xuanfu.It is also believed that the Xuanfu-opening method should be used through the whole process of the treatment for pneumonia with dyspneic cough in children.As for the basic pathological changes of qi stagnation,phlegm obstruction,blood stasis and deficiency of qi,blood and body fluid in children with pneumonia with dyspneic cough,it is pointed out that the following methods can be used in clinical treatment according to the differentiation of disease symptoms:ventilating lung to open Xuan,clearing heat to open Xuan,resolving phlegm to open Xuan,removing blood stasis to open Xuan and tonifying deficiency to open Xuan,with the hope to provide new ideas for the clinical diagnosis and treatment of pneumonia with dyspneic cough in children.
