目的 :通过西宁市 (海拔 2 2 6 0m)与平原南京市 (海拔 1 5m) 5 0岁～ 6 0岁老年人胸部X线征像改变 (肺纹理、右下肺动脉、肺动脉段与心胸比率测量 )找出X线征像的差异点 ,以提高老年人胸部X线诊断水平 ;方法 :用居住在高海拔地区 1 0年以上无胸部疾患的5 0岁～ 6 0岁 1 0 0例老年人正常胸片与平原地区 (南京市 ) 1 0 0例同龄正常老年人的胸片对照分析 ;结果 :高海拔地区老年人的胸部肺纹理、右下肺动脉、肺动脉段和心胸比率测量较平原地区老人有较大的X线差异 ;结论 :高原缺氧、寒冷、干燥和冬季长等特点可造成高海拔地区老年人胸部有明显的X线形态改变
OBJECTIVE: To investigate the change of chest X-ray findings in 50 years old and 60 years old in Xining (elevation 2260m) and Nanjing plain (Nanjing elevation 1 5m) ) To find out the difference of X-ray signs in order to improve the diagnostic value of chest X-ray in the elderly.METHODS: A total of 100 elderly people aged 50 to 60 years with no chest disease who lived in high altitude area for more than 10 years The chest radiographs of the normal chest radiographs were compared with the normal chest radiographs of 100 normal aged people in plain areas (Nanjing). Results: The chest lung texture, right lower pulmonary artery, pulmonary artery segments and cardiothoracic ratio in the elderly were higher than those in the plain There is a big difference in X-ray; Conclusion: Plateau hypoxia, cold, dry and winter long and other characteristics can cause high altitude chest X-ray obvious changes in the shape
