摘要 目的研究煤工尘肺患者血清高迁移率族蛋白B-1(HMGB1)与肺功能的关系,为煤矽肺的早期防治提供理论依据。方法选择某矿务局体检机构的不同期别煤工尘肺患者作为人群试验采集对象,共1 126例,其中0+期624例,Ⅰ期324例,Ⅱ期120例,Ⅲ期58例。采集患者血清,采用酶联免疫吸附的方法测量HMGB1的表达,采用肺功能仪HI-801进行肺功能测定。均数的两两比较采用bonferroni法,对应的检验水准调整为α=0.008;相关分析采用Spearman秩相关,检验水准α=0.05。结果 (1)Ⅱ期煤工尘肺患者血清HMGB1浓度与其他3期相比较均有统计学差异(P均<0.008)。(2)随着尘肺期别增加,患者血清中HMGB1浓度逐渐升高(P<0.008)。(3)煤工尘肺患者血清HMGB1浓度与反映肺功能的3个指标VC、FVC、FEV1均呈负相关,相关系数分别为-0.734、-0.912、-0.893(P均<0.05)。提示随血清HMGB1浓度的升高,VC、FVC、FEV1均降低。结论煤工尘肺患者血清HMGB1浓度的升高可反映肺功能的损伤。
