Abstract Besides nuclear DNA,mitochondrial DNA(mt DNA) is also a genetic substance in human body and may be damaged more often than nuclear DNA.With PCR amplification,the authors analyzed the 7.436kb mtDNA deletion in fifty individiuals,an age-dependent increase of mtDNA deletion was found in myocardial cells and blood lymphocytes and multiple deletion was found within lymphocyte mtDNA.The amount of deleted mtDNA was about one tenth that of normal mtDNA.It is suggested that mitochondrial DNA deletion might be...

用聚合酶链反应(PCR)技术对50例心脏病患者及健康人线粒体DNA(mtDNA)中遗传物质缺失的研究发现,随年龄增长,发生缺失的mtDNA比例增加。淋巴细胞和心肌细胞mtDNA均存在包含有7.436kb缺失的片断,而前者有多重缺失,发生缺失的mtDNA片断约占正常mtDNA的10.3%。提示mtDNA的缺失可能在衰老和老年人心脏病的发生机制中有一定意义。

运用自然实验法探讨4—6岁幼儿在物质缺失的条件下交往策略的特点以及他们在年龄、类型、性别维度上的分布特征。结果表明:随年龄增长,幼儿交往策略的水平在不断提高,但以5岁幼儿提高最为明显;性别特征不影响幼儿发起、协调、交换等交往策略的水平;在交换的四种类型中,按人数多少的顺序,依次为A型、C型、D型、B型。

Purpose To study the relationship between mucin production by colorectal carcinoma cells and the tumor invasion and metastasis. The significance of the collagen IV expression in tumor stroma was also evaluated. Methods Four hundred and twenty four specimens of colorectal carcinomas have been clinicopathologically studied. Many variables such as tumor site, age, histologic type, grade of tumor differentiation, Dukes classification and the percentage of mucin were analyzed. The immunohistochemistry was used...

Purpose To study the relationship between mucin production by colorectal carcinoma cells and the tumor invasion and metastasis. The significance of the collagen IV expression in tumor stroma was also evaluated. Methods Four hundred and twenty four specimens of colorectal carcinomas have been clinicopathologically studied. Many variables such as tumor site, age, histologic type, grade of tumor differentiation, Dukes classification and the percentage of mucin were analyzed. The immunohistochemistry was used for testing the expression of collagen Ⅳ in 109 specimens. Results There was a correlation between the percentage of mucin and depth of invasion,nodal involvement and distant metastasis. The percentage of extracellular mucin showed no significant relation to the grade of tumor differentiation. The decreased, even absence expression of the collagen Ⅳ was found in most cases. The higher the percentage of mucin, the severer the absence of collagen Ⅳ expression. Conclusion The functional differentiation of the mucin production related to the potential of invasion and metastasis. The tumor which produce more mucin tends to follow an aggressive clinical course. The absence of the base membrane substance such as collagen IV might be the cause of the aggressive biologic behaviour in colorectal carcinomas.

目的:观察不同组织类型的大肠癌粘液分泌功能与浸润、转移的关系以及基底膜主要成分ColⅣ的表达情况。方法:对424例大肠癌进行临床病理分析及IV型胶原免疫组化标记。结果:大肠癌组织粘液含量越高,浸润越深,淋巴结及远处转移率越高;粘液含量与癌组织分化程度关系不大;癌组织中ColⅣ普遍缺失,粘液含量越高,ColⅣ缺失越明显。结论:大肠癌粘液分泌功能分化与侵袭、转移能力呈正相关,这种能力可能与ColⅣ等基底膜物质的缺失有关
