Abstract： 目的:检测克罗恩病(CD)和溃疡性结肠炎(UC)肠黏膜组织中IL-27 p28 mRNATL其蛋白、IL-27受体mRNA的表达,探讨其在CD和UC中的发病意义.方法:应用反转录-聚合酶链反应(RT-PCR)和蛋白质免疫印迹(Western blot)方法检测炎症性肠病患者炎症肠黏膜组织中IL-27 p28基因及蛋白、IL-27受体基因的表达,并与健康者作对照.结果:IL-27 p28 mRNA在CD患者中的阳性率和灰度分析表达较UC患者明显增高(X2=6.64,P<0.05;t=11.01,P<0.01),IL-27受体阳性率和灰度分析在CD患者较UC患者和健康对照者明显增高(阳性率:X2=10.91,P<0.016,X2=18.84,P<0.016).IL-27蛋白阳性率和灰度分析在CD患者中表达明显高于UC患者(X2=5.24,P<0.05;t=3.37,P<0.05),并且IL-27mRNA的表达与蛋白质表达密切相关.结论:IL-27 p28及其受体的上调,可能有助于CD患者炎症发展过程.
