Analysis of Professor Xu Yanling's experience in treating pulmonary interstitial fibrosis
Pulmonary interstitial fibrosis is the end-stage change of many pulmonary diseases.Most of the diseases are chronic and progressive.Its pathogenesis is still unclear enough,and the morbidity and mortality are increasing day by day.Traditional Chinese medicine plays a unique advantage in dealing with this disease,which can not only effectively alleviate the clinical symptoms of patients,but also delay the progress of the disease to a certain extent,thus improving the quality of life of patients.Professor Xu Yanling,a famous TCM doctor in Liaoning Province,has been engaged in the diagnosis and treatment of respiratory diseases for more than 40 years and has rich clinical experience.Combining with the ancient litera-ture,Prof.Xu Yanling advocates recognizing pulmonary interstitial fibrosis from"fei bi"and"fei wei".Both deficiency of Qi and Yin in lung and kidney is the root cause of pulmonary interstitial fibrosis.The prolonged deficiency of the healthy-Qi leads to poor distribution of body fluids and generation of phlegm-fluid retention,which obstruct the Qi activity.The im-paired dispersing and descending of the lung causes the generation of phlegm and blood stasis to block the lung collaterals.The pathogenesis of"fei bi"is phlegm and blood stasis as the manifestation of the disease.Pulmonary interstitial fibrosis is caused by both deficiency of Qi and Yin in lung and kidney.Prolonged insufficiency of body fluids causes the deficiency-fire to burn the lung,and the loss of nourishment in lung collaterals,producing shriveled and weak lung lobes.Or prolonged de-ficiency of the root leads to the generation of phlegm and blood stasis,which transform into the heat-toxicity to burn the lung collaterals,finally producing shriveled and weak lung lobes.This is the pathogenesis of"fei wei"based on the root-deficiency.The pathogenesis is both deficiency of lung and kidney as the root cause and blocked lung collaterals by phlegm and blood stasis as the manifestations.The invasion of exogenous pathogens is the main cause of disease deterioration.This paper puts forward the therapeutic methods of invigorating Qi and nourishing Yin to treat its root cause,removing blood stasis and resolving phlegm to eliminate its manifestations,and strengthening the body resistance to eliminate pathogenic factors.
