肺纤维化的原因（Causes of pulmonary fibrosis） Causes of pulmonary fibrosis There are many reasons for pulmonary fibrosis, we can only better understand the cause of disease. There are many pathogenic factors of pulmonary fibrosis, and they are near us. They will live in the pathogenic environment of pulmonary fibrosis. The name of the disease, pulmonary fibrosis, lung interstitial tissue by collagen, elastin and protein carbohydrate composition, when fibroblasts by chemical or physical damage, secrete collagen interstitial tissue repair, and cause lung fibrosis; lung is hurt, the body repair result. What are the causes of pulmonary fibrosis? Pulmonary fibrosis caused by many reasons, there is a common physical and chemical factors, environment, occupation, etc., such as asbestos, mineral, dust, chemotherapy, radiation injury, inhalation of harmful gases; contact with pigeon droppings, animal fur, mildew Bacillus caused by exogenous allergic pulmonary alveolar inflammation, can lead to pulmonary fibrosis; some autoimmune rheumatic diseases, such as systemic lupus erythematosus, rheumatoid arthritis, Sjogren syndrome, dermatomyositis, scleroderma, etc., can also be associated with pulmonary fibrosis, pulmonary fibrosis sometimes occurs even in. Secondary infection is the main cause of death. There is still a lack of satisfactory treatment for pulmonary fibrosis. Western medicine is mainly based on the use of adrenal cortical hormone and immunosuppressive drugs. Corticosteroids inhibit the inflammatory cells, thereby reducing collagen synthesis (Note: studies have shown that the formation of collagen synthesis, to a certain extent can lead to pulmonary fibrosis), blocking pulmonary fibrosis. But it also inhibits the production of collagenase, so the effect is not ideal, and the adverse reactions are obvious. In addition, long-term use of corticosteroids can make the body immunity decline, so that latent infection foci spread or induce new infections, and severe secondary infec
