摘要
目的观察皮肤损伤的煤焦油沥青职业接触工人体内生物标志物的变化。方法采用整群抽样方法,选择职业接触煤焦油沥青且出现皮肤异常的55名工人为皮损组,以职业接触煤焦油沥青且未出现皮肤异常的455名工人为对照组。采集2组人群班后尿及血样,分别进行尿中1-羟基芘、1-羟基萘、2-羟基萘的水平及尾部DNA百分含量、Olive尾矩检测。结果皮损组人群尿中1-羟基芘水平、尾部DNA百分含量、Olive尾矩均高于对照组(中位数:18.78 vs 5.75μg/g肌酐、14.6%vs 12.1%、3.25 vs 2.22μm,P<0.01)。多因素Logistic回归分析显示,尿中1-羟基芘、1-羟基萘、2-羟基萘以及尾部DNA百分含量、Olive尾矩、工龄均是皮肤损伤的影响因素(P<0.05)。结论 1-羟基芘、1-羟基萘、2-羟基萘、尾部DNA百分含量、Olive尾矩均可作为职业接触煤焦油沥青所致皮肤损伤的生物标志物。
