1、肺癌组织缺氧诱导因子一1Q表达与肿瘤血管生成的关系硕士研究生:杨海玉导师:石小玉教授中文摘要目的:探讨肺癌组织中缺氧诱导因子一1a的表达与肿瘤血管生成的关系。方法:选取外科手术切除肺癌组织标本100例,其中男58例,女42例,年龄:39—71岁,平均65.2岁。组织学类型:鳞状细胞癌45例、腺癌38例、●●小细胞癌1l例、大细胞癌6例。淋巴结转移状况:阳性63例、阴性37例。临床分期:I期37例,II期21例,III期36例,IV期6例。采用组织芯片技术构建肺癌组织芯片(包括100例肺癌组织和20例正常肺组织),通过
2、免疫组织化学和原位分子杂交方法检测肺癌组织中HIF-1Ⅱ、HIF一1QmRNA、VEGF和VEGFmRNA的表达,用CD34单克隆抗体标记血管内皮细胞并计数微血管密度(MvD)。结果:肺癌组织中HIF-1Q、HIF-1QmRNA、VEGF、VEGFmRNA的阳性表达率均明显高于正常肺组织(P(O.01);HIF一1Q、HIF一1amRNA、VEGF、VEGFmRNA的表达与肺癌组织学类型无关(P>O.05);淋巴结转移阳性组中的HIF一1Ⅱ、HIF-1ⅡmRNA、VEGF、VEGFmRNA阳性表达率显著高于淋巴结转移
3、阴性组(PO.05);HIF~1a、HIF一1Q2mRNA与VEGF、VEGFmRNA表达之间均呈正相关(P0.05);淋巴结转移阳性组中的平均MVD值显著高于淋巴结转移阴性组
