摘要 目的探讨Toll样受体4(TLR4)蛋白在胃癌发生、发展中的作用及机制。方法采用免疫组化法检测52份胃癌组织及30份正常胃组织标本中TLR4蛋白表达;采用CD34抗体标记微血管内皮细胞,计算微血管密度(MVD)。分析TLR4蛋白表达、MVD与胃癌主要临床病理参数的关系。结果胃癌组织TLR4蛋白阳性率和MVD分别为76.9%和32.5±8.3,均显著高于正常胃黏膜(P<0.01);有淋巴结转移者TLR4阳性率显著高于无淋巴结转移者(P<0.05);TNM分期为Ⅲ+Ⅳ期者TLR4蛋白表达率明显高于Ⅰ+Ⅱ期者(P<0.05)。MVD与肿瘤TNM分期、淋巴结转移及分化程度密切相关(P<0.01,P<0.05)。Spearman等级相关分析表明,TLR4蛋白表达与MVD呈显著正相关(P<0.01)。结论 TLR4蛋白表达与胃癌的发生发展密切相关,其机制可能为促进肿瘤血管生成。
