| 摘 要： | 目的 探讨血管生长因子在有血吸虫病和无血吸虫病的大肠癌患者肠组织中的mRNA和蛋白表达差异。方法 收集30例有血吸虫病及30例无血吸虫病大肠癌患者的大肠癌手术切除标本中的正常肠组织、 癌旁组织和癌组织， 采用荧光实时定量PCR和Western blot检测不同组织中血小板衍生内皮细胞生长因子 （PD?ECGF） 和血管内皮生长因子（VEGF） 的mRNA和蛋白表达水平。结果 有血吸虫病大肠癌患者正常组织、 癌旁组织及癌组织中PD?ECGF mRNA和VE? FG mRNA相对表达量是无血吸虫病患者的1.726、 1.766、 2.729倍和2.138、 1.831、 3.376倍， 有血吸虫病大肠癌患者正常组织、 癌旁组织及癌组织中PD?ECGF和VEGF蛋白表达水平均显著高于对应的无血吸虫病患者肠组织中的表达水平 （P均 < 0.05）。结论 血管生长因子PD?ECGF和VEGF在有血吸虫病大肠癌患者肠组织中的表达水平高于无血吸虫病患者， 血吸虫病可能是大肠癌发病的高危因素之一。

| Abstract: | Objective To investigate the differences of mRNA quantitation and protein expression of vascular growth factorsincluding platelet?derived endothelial cell growth factor（PD?ECGF）and vascular endothelial growth factor（VEGF）in intestinaltissues in colorectal carcinoma patients with and without schistosomiasis. Methods Thirty colorectal carcinoma patients withschistosomiasis and 30 colorectal carcinoma patients without schistosomiasis were included in this study. The mRNA quantitationand protein expression of PD?ECGF and VEGF in the normal tissue，peri?carcinoma tissue as well as carcinoma tissue obtainedfrom surgical specimens were detected by qRT?PCR and Western blot. Results The mRNA relative quantitations of PD?ECGF innormal tissue，peri ?carcinoma tissue and carcinoma tissue in the colorectal carcinoma patients with schistosomiasis were 1.726，1.766 and 2.729 times to those in the colorectal carcinoma patients without schistosomiasis，respectively. The corresponding onesof VEGF were 2.138，1.831 and 3.376 times，respectively. The protein expression levels of PD?ECGF and VEGF in normal tis?sue，peri?carcinoma tissue and carcinoma tissue were higher in the colorectal carcinoma patients with schistosomiasis than in thecolorectal carcinoma patients without schistosomiasis. Conclusions The expressions of vascular growth factors including PD?EC?GF and VEGF are higher in the colorectal carcinoma patients with schistosomiasis than in the colorectal carcinoma patients withoutschistosomiasis. Therefore，schistosomiasis may be one of the risk factors of colorectal cancer. |
