Abstract： 目的 比较Ⅱ期煤工尘肺患者与接尘工人血清蛋白质的表达差异.方法 以病例与对照尽可能齐同为原则,选择了4对Ⅱ期煤工尘肺病例和接尘对照者,采静脉血,分离血清,以固相pH梯度等电聚焦为第一向和垂直SDS聚丙烯酰胺凝胶电泳为第二向.进行蛋白分离,然后做图谱分析和质谱鉴定.结果 接尘工人和Ⅱ期煤工尘肺患者血清差异蛋白质点共有1596个,其中差异大于2倍的蛋白质点共有123个.对两组血清差异蛋白质中差异最大的16个点进行了鉴定,共鉴定出14个点的蛋白质,其中,8个蛋白质点在Ⅱ期煤工尘肺患者中是上调的,6个蛋白质点在Ⅱ期煤工尘肺患者是下调的.结论 Ⅱ煤工尘肺患者与接尘工人血清蛋白质的表达存在差异,需要进一步研究证实.
