Interstitial lung disease is a difficult respiratory disease published by WHO, which involves more than 200 diseases. Its etiology and pathogenesis are very complicated. The clinical manifestations are cough and progressive dyspnea. There are few modern treatment methods. The medical team of Department of Respiration has established a "Big Beijing" pulmonary interstitial disease qualified expert clinical, imaging, pathology consultation platform according to the multi-disciplinary "MDT" diagnosis and treatment paradigm in the international respiratory field. Inheriting the academic experiences in the treatment of "lung impotence" and "lung paralysis" of famous traditional Chinese medicine physicians in our hospital such as Xu Gongyan, Cao Xiping and Lin Jiehao, we can not only make a clear diagnosis in the early stage, but also make a comprehensive treatment plan of individualized "integrated internal and external treatment" combining with traditional Chinese and Western medicine for patients.
