Homogeneous and polymer-anchored multimetallic catalysis has attract-ed much attention in recent years,since enhanced reacton rates,selectivitiesand new types of reaction are expected to arise from cooperative or succes-sive participation of two or more kinds of metal atom[1-3].Because of numer-ous possible combinations,bimetallic catalysts demonstrate great potentialto be tailored with respect to activity,selectivity and stability which some-times might not be achieved by a monometallic catalyst.The carbonylation

目的 探讨抑癌基因P15蛋白在脑胶质瘤发生、分化过程中的作用及其与预后的关系,以指导临床治疗方案的选择和判断患者的预后.方法采用免疫组化的方法检测68例脑胶质瘤患者病理标本中的P15蛋白,分析P15蛋白的缺失与病理分级及患者预后之间的关系.结果全组共有20例患者(29.4%)标本P15蛋白表达阴性,Ⅲ、Ⅳ级脑胶质瘤的P15蛋白的阴性率明显高于Ⅰ、Ⅱ级脑胶质瘤P15蛋白的阴性率(P<0.05).P1
