Abstract:

目的探讨高迁移率转移族蛋白(HMGB1)和晚期糖基化终末产物受体(RAGE)在口腔扁平苔藓(OLP)中的表达及意义。方法选择经病理确诊的OLP患者和健康体检者各30例,采用免疫组化法观察HMGB1及RAGE蛋白在其口腔黏膜组织中的表达情况;运用实时荧光定量PCR技术检测HMGB1及RAGEmRNA在其外周血中的表达量。结果在扁平苔藓患者的口腔黏膜组织中,HMGB1和RAGE的蛋白表达水平均高于健康对照组(P<0.05)。HMGB1与RAGE的蛋白表达水平呈正相关性(r=0.473,P<0.05);在口腔扁平苔藓患者外周血中,HMGB1和RAGE的基因表达水平均高于健康对照组(P<0.05);HMGB1与RAGE的基因表达水平呈正相关性(r=0.922,P<0.05)。结论HMGB1和RAGE协同参与了OLP的发病过程,其机制有待于进一步研究。
