The authors made a dynamic observation of 103 cases of dust-induced bronchitis in mechanical industrial workers. There were 98 males and 4 females. Dust-over age> 10 years in 95 cases. 62 cases of castings contacted with quartz dust, 30 welders contacted with mixed dust, and 11 cases of polisher. Dynamic observation of 2 to 18 years, most in 5 years. At the beginning of observation, 86 cases were less than 50 years old; when the observation was over, 66 cases were older than 50 years old. Dynamic observation items include clinical, X-ray (chest X-ray, chest X-ray, three-phase chest radiograph, recording wave), respiratory function (breath chart, residual gas oximetry), cardiovascular system (electrocardiogram), bronchoscopy , Plasma protein, C-reactive protein.
