Abstract:
Objective:To compare the clinical and imaging characteristics of patients with stage I coal worker's pneumoconiosis (CWP) .Methods:All 347 cases of coal workers' pneumoconiosis diagnosed in the Third Hospital of Peking University from January 2014 to December 2018 were included in the study. According to different working posts, the subjects were divided into three categories: mining, tunneling and mixing workers. Dust exposure duration, initial dust exposure age, diagnosis age, latency, small shadow shape and lung regions distribution in X-ray chest film of different categories of CWP patients were analyzed.Results:Among the 347 patients, 216 were mining workers (62.2%) , 77 were tunneling workers (22.2%) and 54 were mixing workers (15.6%) . The dust exposure duration of mining, tunneling and mixing workers were (14.5±7.0) , (16.3±8.2) and (19.0±8.8) years, respectively. There are statistically significant differences in dust exposure duration between different categories of workers ( P<0.05) . There were no significant difference in the age of diagnosis, initial dust exposure age and the latency between different categories of workers ( P>0.05) . The X-ray films of mining, tunneling and mixing workers showed small round shadow, accounting for 50.9% (110/216) , 96.1% (74/77) and 96.3% (52/54) respectively. 48.1% (104/216) of the mining workers and 38.9% (21/54) of mixing workers, the distribution of small shadow in chest X-ray films reached middle and lower lung regions, while in the 48.1% (37/77) of the tunneling workers, the distribution of small shadow in chest X-ray films reached lower lung regions. There were differences in above indicators among workers with different categories ( P<0.05) . Conclusion:The dust exposure duration, the shape and the distribution of lung area on chest X-ray films are different in stage I CWP patients of different occupational categories.
