Methods From April,2001 to May, 2010,41 patients underwent tricuspid valve repair to treat severe TR were studied. Twenty-one patients were done artificial ring annuloplasty alone (group R) and twenty patients were done artificial ring annuloplasty associated with edge to edge valve repair (group E) . All the展开更多

目的:观察CHFR和P53蛋白的表达与胃癌临床病理学特征的关系,探讨其在胃癌发生发展过程中的作用及相关的分子机制.方法:利用组织芯片制作仪(美国),构建成5个包括151例胃癌及101例与其配对的正常胃黏膜、肠化生或不典型增生的组织芯片蜡块...目的:观察CHFR和P53蛋白的表达与胃癌临床病理学特征的关系,探讨其在胃癌发生发展过程中的作用及相关的分子机制.方法:利用组织芯片制作仪(美国),构建成5个包括151例胃癌及101例与其配对的正常胃黏膜、肠化生或不典型增生的组织芯片蜡块.采用Envision免疫组化二步法检测151例胃癌及101例配对癌旁胃黏膜组织中CHFR蛋白和P53蛋白的表达.结果:CHFR蛋白在非癌胃黏膜组织中阳性表达率为85.25%(52/61),在胃癌组织中阳性表达率显著降低(49.67%,75/151,P<0.05);CHFR表达下调或缺失与胃癌患者的性别显著相关,女性患者胃癌组织中CHFR表达缺失率显著高于男性患者(64% vs 43.56%,P<0.05).BorrmanⅢ+Ⅳ型胃癌组织中CHFR表达缺失率显著高于BorrmanⅠ+Ⅱ型胃癌(57.14% vs 34.78%,P<0.05).虽然不同组织学类型胃癌之间CHFR的表达无统计学差异,但本研究发现胃印戒细胞癌组CHFR表达缺失率最高(71.43%).胃癌组织中CHFR蛋白的表达缺失与肿瘤浸润深度、淋巴结转移以及mP53蛋白表达未见显著相关性(P>0.05).结论:有丝分裂前期检查点CHFR基因表达下调或缺失在胃癌中是频发事件.可能参与胃癌的发生,其与女性、弥漫浸润型胃癌发生发展的关系可能更为密切.展开更多
