1、兰州医学院硕士学位论文胃癌端粒酶、VEGF、PCNA表达的临床研究姓名:赵晓宁申请学位级别:硕士专业:人体解剖与组织胚胎学指导教师:宋焱峰2003.3.1一兰型堕兰堕竺±兰竺堕苎一——胃癌端粒酶、VEGF、PCNA表达的临床研究摘要目的研究胃癌组织中的端粒酶、vascularendothelialgrowthfactor(VEGF)、proliferatingcellnuclearantigen(PCNA)的表达与临末病理因素的相关性及临床意义。方法胃癌患者癌组织标本70例,对照组为胃镜取材的正常胃组织标本,26例。
2、用PeR—ELISA法测定端粒酶的活性,免疫组化方法测定VEGF、PCNA在癌组织中的表达。结果胃癌组织中端粒酶活性表达率为88.6%(62/70),对照组为15.4%(4/26),两者比较有显著性差异(P0.05),但随着临床病理分期的增高,癌组织中端粒酶活性阳性检出率有逐渐增高的趋势;VEGF在胃癌组织中的阳性表达率为68.6%(48/70),对照组为7.7%(2/26),两者比较有显著性差异(P3、,VEGF的表达与组织分化的高低密切相关LP4、作为胃癌的特异性诊断指标:也可作为胃癌的预后判断指标。关键词端粒酶,胃癌,VEGF,PCNA,临床病理,临床意义兰州匿学院砸{’学位论文THECLINICALSTUDY0NTHEEXPRESSIONSOFTELOMERASE,VEGF’ANDPCNAINHUMANGASTRICCANCERABSTRACTObjectiveTostudytheclinicalsignificanceand"therelationshipbetweentheexpressionsoftelomerase,vascularendothel5、ialgrowthfactor(VEGF).proliferatingcellnuclearantigen(PCNA)aI】dclinicpathologicfeaturesinhumangastriccancer.Methods70specimensofhumangastriccaucerand26specimensofnormalgastrictissueswerechosenforstudyTheactiviu7oftelomerasewasdetectedbyPCR-ELISAassay.Theexpress6、ionsofVEGFandPCNAweremeasuredbySPlmmunohistochemicalmethodResultsTheexpressionrateoftelomerasewas88.6%(62/70)ingastriccancerI5.4%(4126)incontrolsIP7、emiation.tumorinvasiondepth.TNMstageorlymphnodemetastasis(P>005).ThepositiveratesoftelomeraseincreasedwiththegradesofTNM.ThepositiverateofVEGFvvas68.8%(48170)ingastriccancel'.7.7%incontrols(P8、histo—differentiation,TNMstageand13mphnodemetastasiswasobserved(P<0.05).ThepositiverateofPCNAwas72.9%(51/70)ingastriccancer,19.2%(5/26)incontrols(P<0.01),andthecorrelationbe
