本文报道了高原矿工矽肺Ｘ线胸片分析。移居高原（２５００ｍ）６３例煤矿工人连续２０年定期拍摄Ｘ线胸片，按居住年限进行自身对照，取心血管Ｘ线四项指标，并观察矽肺的Ｘ线图象演变过程。结果表明：移居高原矿工矽肺患者右肺下动脉横径、肺动脉段突度、降支与气管横径比值及心脏横径四项参数，５年后呈显著改变。移居高原矽肺患者接触粉尘时间愈久、其类型改变程度愈趋显著，症状愈重，预后愈差。
This paper reports a plateau miners silicosis X-ray analysis. In the plateau (2500m), 63 coal miners took X-ray radiographs regularly for 20 consecutive years. According to their living years, they took self-control and took cardiovascular X-ray four indexes and observed the evolution of X-ray image of silicosis. The results showed that four parameters of the diameter of right inferior pulmonary artery, the degree of pulmonary artery, the ratio of descending branch to trachea and the transverse diameter of heart were all significantly changed in silicosis patients who migrated to plateau. The longer the contact time of patients with silicosis who migrated to the plateau, the more obvious the type of change, the more severe the symptoms and the poorer the prognosis.
