1、浙江大学硕士论文有统计学差异(只0.05)。甲状腺乳头状癌MUCI异常表达率56.6%,正常甲状腺组织MUCI异常表达率5%,结节性甲状腺肿组织MUCI异常表达率巧%,甲状腺乳头状癌与后二者之间有显著性差异。甲状腺乳头状癌日一catenin异常表达率71.7%,正常甲状腺组织p一Catenin异常表达率20%,结节性甲状腺肿组织p一Catenin异常表达率40%,甲状腺乳头状癌与后二者之间有显著性差异。MUCI灰度值测定按有无淋巴结转移分,按肿瘤直径)1cm和2、移分,两组之间有统计学差异(只0.05)。二分Logistic回归显示,显著影响甲状腺乳头状癌发生的因素有MUCI的异常表达、p一cate垃n的异常表达、性别(女性好发)(尸<0.05);与MUCI的表达率有显著相关的因素为有无淋巴结转移、p一catenin的异常表达和性别(女性好发)(尸<0.05)。结论:MUCI的异常表达在甲状腺乳头状癌的发生、进展和转移中有重要意义,它可以作为甲状腺乳头状癌恶性行为的预测因子。MUCI的表达和p一。atenin的表达有显著相关性,提示MUCI一p一catenin途径可能是甲状腺乳头状癌发病机制的一部分3、。[关键词】甲状腺乳头状癌;MUCI粘蛋白;一p一catenin浙江大学硕士论文THEEXPRESSIONANDCLINICALSIGNIFICANCEOFMUCIANDp一CATENININPAPILLARYTHYROIDCARCINOMAPOSTGRADUATEHEFEIMENTORSLlHONGAbstraetBaekgroundandObjeetive:ToinvestigatetheexPressionsofMUCI/p一eatenininthetissuesofthePaPillarythyroidcareinoma,theno4、dulargoiterandtheeonirols,andtoexPloretherelationshiPbetweentheirexPressionsandthecareinogenesisanddeveloPmentofthePaPillaxythyroidcareinoma.BaekgroundandMethods:TheeXPressionsofMUCIandp一eateninweredeteetedbyinununohistochemiealmethodin53easesofmalignantthyroidtissues,20ea5、sesofbenignthyroidtissues,and20casesofnormalthyroidtissues,reSPeetively.53easesofthePaPillarythyroidearcinomaweredividedintosubgrouPsaeeordingtotheeliniealfeal刀ressuehasthesizeoftunlor,withmetastatielymPhnodesornot,ageandsex.ThecorrelationsoftheexPressionsofMUCI/p一eateninw6、iththeelinicalPatholQgiealParametersofthePaPillarythyroidearcinomawereanalyzed、Results:TheexPressionofMUCIinthetissuesofthePaPillarythyroidcarcinomainereasedsignifieantly(134.5士10.3,grayscale)eomParedwiththoseofthenodulargoiter(101.0士7.2,grayscale)andthecontrols(99.1士5.6,g7、rayscale)(P<0.05).The浙江大学硕士论文PositiveeXPressionratesofMUCIinthetissuesofthePaPillaryt翰roid、eareinoma,thenodulargoiterandthecontrolswere56.6%,15%,ands%,resPeetively.ThePositiveexPressionratesofp一catenininthetissuesofthePaPillarythyroidearcinoma,thenodulargoiterandtheeontrol8、swere71.7%,40%,and20%,resPectivelyandtherewasasignifieantdiffereneeinitsexPressionratebet
