目的通过调查分析大屯煤矿(姚桥矿和徐庄矿)895名井下掘进工肝脏健康状况,找出问题,为进一步改善卫生防护措施和制定健康保健策略提供科学依据。方法采用自行设计的《接尘作业人员调查表》对大屯煤矿井下作业人员进行问卷调查,B超检查由大屯煤矿医院内科医师完成,肝脏生化指标检查由医院检验科完成,对所有资料用EpiData3.1软件建立数据库、State 10.0软件对调查结果进行统计分析。结果矿工脂肪肝检出率为29.05%,丙氨酸氨基转移酶(ALT)异常率为8.49%。大屯两个煤矿比较,姚桥矿井下掘进工ALT活力、总胆红素(TBIL)、直接胆红素(DBIL)增高检出率明显高于徐庄矿,脂肪肝、肝囊肿的异常检出率也均明显高于徐庄矿(P<0.01)。经常饮酒是脂肪肝主要的独立危险因素之一。结论脂肪肝是大屯煤矿掘进工最主要的肝脏疾病之一,矿工肝生化指标异常以及脂肪肝等肝脏病变检出率高与工人生活习惯有一定的关系。
Objective To find out the problems by investigating and analyzing the liver health conditions of 895 underground tunneling workers in Datun Coal Mine (Yaoqiao Mine and Xuzhuang Mine), and provide scientific basis for further improvement of sanitary protection measures and formulation of health care strategies. Methods A questionnaire survey of miners in Datun Coal Mine was conducted by using the self-designed questionnaire of dust pick-up workers. The B-ultrasound was performed by physicians in Datun Coal Mine Hospital. The biochemical tests of liver were completed by the hospital laboratory. EpiData3.1 software to establish a database, State 10.0 software for statistical analysis of the survey results. Results The detection rate of fatty liver in miners was 29.05%, and the abnormal rate of alanine aminotransferase (ALT) was 8.49%. Compared with Datun Coal Mine, the detection rate of ALT activity, total bilirubin (TBIL) and direct bilirubin (DBIL) in underground tunneling workers of Yaoqiao Mine was significantly higher than that of Xuzhuang Mine, fatty liver and hepatic cyst The rates were also significantly higher than Xuzhuang mine (P <0.01). Regular alcohol consumption is one of the major independent risk factors for fatty liver disease. Conclusion Fatty liver is one of the most important liver diseases in Datun coal miners. The abnormal liver biochemical indexes of miners and the detection rate of liver diseases such as fatty liver have a certain relationship with the living habits of workers.
