1、安徽医科大学硕士学位论文5.E.cadherin与beta·catenin的相关。}生及两者联检的意义E-cad与beta.cat在不同宫颈病变组织中的阳性表达具正相关性(r=0.432,P2、性程度及生物学行为。结论:1.E.cad和beta.cat的异常表达是CIN的早期信号,与CIN级别密切相关,可以作为CIN分类的一个附加标准。2.E.cad和beta.cat的异常表达与宫颈疾病的进展有关,同时参与了宫颈肿瘤由良性向恶性转变的过程。3.对E.cad和beta.cat进行联合检测,可以极大的提高对诊断的敏感性及更准确地判断宫颈疾病的生物学行为。4.E.cad、beta.cat表达水平的高低可能成为有价值的临床诊断指标以及肿瘤病理诊断和预后标志物。关键词:子宫颈癌;宫颈上皮内瘤样病变;E-钙粘附蛋白;Beta.连接素;免疫组织化学安徽医科大学硕士学位论文StudyonClini3、calSignificanceofE-cadherinandBeta-cateninExpressionsinCINandCervicalCarcinomaOBJECTIVEABSTRACTTostudyadhesionsofE—cadhefinandbeta—cateninexpressionsandtheirclinicalsignificanceincervicalintraepithelialneoplasia(C呻anduterinecervixcancer,andtoinvestigatetherelationshipofthoseindexesandthegenesis、dev4、elopment、invasionandmetastasisofcervicallesion,andthecombinationdetectionofthoseindexs,bywhichtoanalysizethevalueofdiagnosisandpredictionofuterinecervixcancerandprecancerouslesion.E-Cadherinandbeta·catemnwereinvestigatedbytheSPmethodin60c,asesofCIN(20c嬲esofCINl、20casesofCINIIand20casesofC咖II),20cas5、esofcervicalsquamouscelleardnomaand10casesofcervicaladenocarcinoma.Dataobtainedfrom20Casesofnormalcervicalepitheliatissuewereusedascontr01.Thedatawereanalyzedstatistically.RESULTS1.E-cadherinexpressionincervicaltissueInnormalcervicalepitheliatissue,E-cadherinexpressedatthemembranesInCINanduterinece6、rvixcancer,E-cadhefinmembranousexpressionweredeclinegreatly.ThepositiveexpressionratesofE-cadherininnormalcervicalepitheliatissue,CINI,CINII,CINIIIanduterinecervixcancerwere100%(20/20)、80%(16/20)、65%E安徽医科大学硕士学位论文(13/20)、45%(9/20)、23%(7/30),respectively;Tocomparetwogroupsrandomly,thedifferenceofE,-c7、adherinexpressionbetweennormalcervicalepitheliatissueandCINwasasstatisticallysignificantasthatbetweennormalcervicalepitheliatissueandinvasivecarcinomaofcervixuteri(P
