摘要 目的检测胶质瘤中丝氨酸蛋白酶抑制剂(Mapsin)、血管内皮生长因子(VEGF)和CD31标记的微血管密度(MVD)的关系,分析其意义。方法以67例胶质瘤患者的临床资料和术后蜡块组织作为观察组,以非肿瘤性的脑组织(病理科存档)40例作为对照组。应用免疫组化方法检测两组中Mapsin、VEGF和CD31的表达。结果观察组中Mapsin表达的阳性率明显低于对照组,VEGF表达的阳性率明显高于对照组,观察组中MVD值明显高于对照组,观察组中Mapsin和VEGF的阳性率、MVD值与肿瘤的最大径、是否伴有坏死和Ki67增殖指数密切相关。相关分析显示Mapsin和VEGF、Mapsin和MVD的表达均呈负相关性,VEGF和MVD的表达呈正相关性。结论胶质瘤术后组织中Mapsin的阳性率低、VEGF的阳性率高、MVD值高,Mapsin对肿瘤血管生成可能具有抑制作用,Mapsin和VEGF共同调节着肿瘤的发生和进展。
