摘　　要：目的 通过分析江阴市从事开山采石农民工脱尘后的矽肺晋期病例资料,了解脱离矽尘作业后矽肺发病及其晋期规律,为预防和控制疾病提供依据。方法 选择2005—2020年江阴市“中国疾病预防控制信息系统-职业病健康危害因素监测信息系统”上报的矽肺晋期病例网络数据,对矽肺晋期病例的接尘工龄、初次确诊期别、初次确诊年龄和脱尘年限、晋期间隔年限及发病潜伏期等进行分析。结果 2005—2020年江阴市矽肺晋期病例共计87例,均为已关闭开山采石企业的脱尘农民工。脱离粉尘时间<6年初次确诊的病例41例(占47.13%),矽肺以贰期较多(49例,占56.32%),逐级晋期为主。晋期间隔年限≤10年55例(占61.11%),与>10年病例比较差异无统计学意义;晋期间隔年限≤10年病例初诊年龄较大[(59.18±9.22)岁]、发病潜伏期较长[(31.49±8.81)年],与>10年病例比较,差异均有统计学意义(均P<0.05)。66例叁期矽肺的阴影形态以大阴影居多(50例,占75.76%),16例小阴影聚集病例中小阴影形态以q为主(13例,占19.70%)。结论 江阴市从事开山采石农民工多在脱尘后6年内确诊,随着脱尘时间的延长,确诊病例有减少的特点。病例多在确诊后10年内晋期,其中以6~10年居多,发病10年后趋于稳定;该批病例初次确诊时的年龄偏大,发病潜伏期较长。Objective By analyzing the data of progressed cases of silicosis in quarry migrant workers with past dust exposure of Jiangyin City,to investigate the regularity of the occurrence and progress of silicosis after divorcing from dust exposure.Methods The network report data of progressed cases of silicosis in Jiangyin City from 2005-2020 were collected from the "China disease prevention and control information system-Occupational disease and occupational health information monitoring system,to analyze the dust exposure years,stage at initial diagnosis,initial diagnosis age and years of divorcing from dust exposure,interval years of progressed stage,and onset latency.Results There were 87 progressed cases of silicosis in Jiangyin City from 2005 to 2020,and all of these case occurred in the quarry workers of the closed mountain quarry enterprises.41 cases(47.13%) were first diagnosed within six years after divorcing from dust exposure,most of cases were silicosis stage Ⅱ(49 cases,56.32%),and the cases were mainly progressed gradually.55 cases(61.11%) had the interval of progressed stage ≤10 years,and their length of exposure to dust was not statistically significant difference as compared with the cases with the interval >10 years.The age of initial diagnosis was larger[(59.18±9.22)years] and the onset latency was longer[(31.49±8.81)years] in cases with the interval of progressed stage ≤10 years,and the differences were statistically significant as compared with the cases with the interval >10 years(both P<0.05).Cases of silicosis stage Ⅲ with large shadows were common(50 cases,75.76%),and the shadows in "q" form were the main form in 16 cases of small shadow aggregation(13 cases,19.70%).Conclusions Most of the quarrying workers in Jiangyin City are diagnosed within six years after divorcing from dust exposure,and the confirmed cases have a tendency to decrease with the extension of divorcing from dust exposure.The cases progress within 10 years after diagnosis,most are in 6-10 years,and they tends to be st
