本文对移居２５００ｍ海拔２０年内６３名矿工定期连续拍摄后前住胸片，按居住年限，自身对照分析，探讨矽肺的Ｘ线演变进程及其与心血管四项指标改变之间的关系。结果表明：Ｘ线四项指标移居中度高原５年后己出现显著改变。矽肺改变表现出六种类型（细沙、粗粒、大结节、球型、碟翼及铠甲型），且随时间延长其类型改变程度愈趋显著。动态观测心肺Ｘ线及心血管各指标的改变并观察上述类型改变特征，对预测高原人体矽肺的发生，评定矽肺的发展程度及监测指导观察疗效都具有重要的临床实用价值。
In this paper, 63 migrants who lived in an altitude of 2500m for 20 years were photographed before and after continuous radiography. According to their length of life and self-control analysis, the relationship between the evolution of silicosis and the changes of the four indicators of cardiovascular disease was discussed. The results show that: X-ray four indicators moved to moderate altitude after 5 years has changed significantly. Silicosis showed six types of changes (fine sand, coarse grain, large nodules, ball, wing and armor type), and with the passage of time the type of change more and more significant. Dynamic observation of changes of cardiopulmonary X-ray and cardiovascular indexes and observation of the above-mentioned types of changes have important clinical practical value in predicting the occurrence of silicosis in the plateau, assessing the development of silicosis and monitoring and guiding the curative effect.
