1、998TianjinMedJ,October2014,Vo1.42No.10神经纤毛蛋白1、2在大肠癌组织中的表达及意义徐卫国‘苗娜孙红刘云张世伟郝小惠【摘要】目的探讨神经纤毛蛋白(NRP)一1、2在大肠癌组织中的表达及其与微血管密度(MVD)的相关性,以揭示NRP一1、2与肿瘤血管生成的关系。方法采用免疫组织化学方法检测66例大肠癌患者的癌组织、癌旁组织及正常组织中NRP-1、2的表达情况,以CD105标记肿瘤新生血管内皮细胞,计数MVD值。结果(1)NRP一1、NRP一2在大肠癌组织、癌旁组织、正常组织中的表达阳性率分别为71.2%、25.8%、0,及80.3%、15.
2、2%、0,各组间比较差异有统计学意义(P<0.O1)。(2)MVD在大肠癌组织、癌旁组织及正常组织中的计数分别为35.682_+5.542、14.485_+3.301、6.864_+1.771,各组相比差异有统计学意义(F=986.654,P<0.O1)。(3)不同年龄、性别、肿瘤的部位及分化程度的患者NRP—l、2的表达差异无统计学意义。肿瘤>5cm的患者NRP—l阳性表达率较高,肿瘤侵及浆膜及以外、有淋巴结转移的患者NRP一1、2的阳性表达率均较高,不同的Dukes分期患者NRP一1、2阳性表达差异亦有统计学意义(P<0.05)。(4)大肠癌患者不同性别、年龄及肿瘤大小
