职业性肺部疾病是最常见的一类职业病,如何进行有效的防治是职业医学的一项重要课题。本文就职业性肺部疾病研究的若干进展,加以综述,以供参考。 煤工尘肺 煤工尘肺患者的类风湿因子(RF)高于正常人,特别是伴发Caplan综合征者约占70％,伴发进行性大块纤维化(PMF)者约35％的患者RF可以是阳性。调查证明RF与X线尘肺改变无相关性。RF的存在与否並不影响PMF的进展快慢。 Occupational lung disease is the most common type of occupational diseases, and how to carry out effective prevention and control is an important issue in occupational medicine. This article on the progress of occupational lung disease research, to be reviewed for reference. Patients with pneumoconiosis have a higher rheumatoid factor (RF) than their normal counterparts, particularly about 70% of those with Caplan syndrome and about 35% of patients with progressive massive fibrosis (PMF) Can be positive. Survey showed no correlation between RF and X-ray pneumoconiosis. The existence of RF does not affect the progress of PMF.
