为了探讨矽肺病人肺功能动态变化的规律,选择某铁矿职业病防治所确诊的202例男性矽肺病人为研究对象,于2007年对研究对象进行问卷调查、肺功能体检、X射线胸片检查,根据2003年的体检资料按矽肺等级将研究对象分为4组,分析矽肺病人4年前后矽肺晋级及肺功能动态变化情况。结果显示,2007年研究对象的矽肺等级较2003年平均增加了1个小级(按12小级分级),4年期间4组的用力肺活量(FVC)和第1秒用力呼气量(FEV1)均有不同程度的下降,4组下降值比较,差异有统计学意义(P<0.05),FVC、FEV1的下降程度与2003年的矽肺等级均呈正相关(r1=0.74,r2=0.68)。
In order to investigate the regularity of the dynamic changes of lung function in patients with silicosis, 202 cases of male patients with silicosis confirmed by the prevention and treatment of occupational disease in an iron mine were selected as research objects. In 2007, the subjects were investigated by questionnaire, pulmonary function examination and X-ray examination. According to the physical examination data of 2003, the subjects were divided into 4 groups according to the grade of silicosis. The silicosis promotion and pulmonary function dynamic changes of patients with silicosis were analyzed 4 years ago. The results showed that in 2007, the average grade of silicosis increased by 1 level (by 12 subscales) on average in 2003, 4 weeks’ forced vital capacity (FVC) and 1 second forced expiratory volume (FEV1) (P <0.05). The decrease of FVC and FEV1 were positively correlated with the grade of silicosis in 2003 (r1 = 0.74, r2 = 0.68).
