[目的]通过比较肺结核免疫人群和未免疫人群的肺结核和矽肺发病率 ,分析肺结核免疫和矽肺的关系。分析接尘矽肺病人的肺结核免疫力和矽肺反应时间的关系。[方法]X线摄片划分矽肺病组和对照组 ,匹配性别、年龄、工作地区。痰液抗酸染色、PCR和痰培养确认肺结核病例。肺结核皮试阳性但无肺结核病症状的是结核免疫的标准。[结果]结核未免疫组与免疫组发病率的差异有统计学意义 (P<0.05)。两组人群的其他危险因素没有显著差异。本研究发现结核免疫力有反应组和无反应组的反应时间 (反应时间即接触人年数 ,由接触时间乘接触粉尘浓度得出 )差异有统计学意义。[结论]粉尘接触人年数和接触时间均数与结核皮试结果相关。但结核皮试通常用于筛检 ,所以要获得可靠的结论 ,必须联用更精确的检测方法。
[Objective] To analyze the relationship between pulmonary tuberculosis immunity and silicosis by comparing the incidence of tuberculosis and silicosis in both immunized and non-immunized groups. To analyze the relationship between pulmonary tuberculosis immunity and silicosis reaction time in patients with dust silicosis. [Methods] X-ray film was divided into silicosis group and control group, matched gender, age and working area. Sputum acid-fast staining, PCR and sputum culture confirmed cases of pulmonary tuberculosis. Tuberculosis skin test positive but no symptoms of tuberculosis tuberculosis is the standard immunization. [Results] There was a significant difference in the incidence of tuberculosis between the unimmunized group and the immunized group (P <0.05). There were no significant differences in other risk factors between the two groups. The study found that there was a significant difference in the response time (response time, ie the number of years contacted by the contact time, by the contact time by the contact dust concentration) between TB and non-responders in TB immunity. [Conclusion] The number of years of contact with dust and the mean of exposure time are related to the results of the skin test of tuberculosis. However, the TB test is usually used for screening, so in order to obtain credible conclusions, a more accurate test method must be used.
