When a large amount of dust into the lung tissue in a long time, causing pathological changes in lung tissue, often irreversible. In recent years, China uses a great deal of manpower to find drugs for the treatment of silicosis, but with little success. Due to the emphasis on treatment, ignoring the improvement of the environment, new patients continue to occur. Therefore, to do pneumoconiosis research, the key lies in:
