胃癌组织端粒酶活性与催化亚基hTERT表达的关系

研究胃癌、胃黏膜肠化生及正常黏膜组织端粒酶活性与人端粒酶催化亚基(hTERT)表达的相关性及端粒酶激活在胃癌发生中的作用.方法:通过端粒重复序列扩增(TRAP)和逆转录聚合酶链反应(RT -PCR)方法测定3种胃癌细胞株、26例胃癌、10例胃黏膜肠化生和36例正常胃黏膜组织标本端粒酶活性和hTERT表达.结果:3种胃癌细胞株、24例胃癌组织有端粒酶活性;4例肠化生端粒酶活性较弱;36例正常胃黏膜标本未测到端粒酶活性.hTERT在26例胃癌组织、5例肠化胃黏膜中表达;正常胃黏膜无表达.端粒酶活性、hTERT表达与肿瘤的分期和病理分级无关.结论:hTERT在肿瘤形成的早期阶段表达,端粒酶的激活是胃癌形成的关键步骤.

Pathogenesis of congenital pyrimidine 5′ -nucleotidase | deficiency: A study on relationship among erythrocyte morphology, enzyme protein content and activity

Objective: To further explore the mechanism of congenital pyrimidine 5'-nucleotidase I deficiency. Methods; The samples were collected from the family members of a patient with P5'N- I deficiency. The enzyme activities were measured by UMP method and the enzyme proteins were quantified by ELISA while the morphology of peripheral blood cells was observed. Results: The enzyme contents reduced as their enzyme activities decreased in the family especially in four members. There was a significant positive correlation(r =0. 955) between the activity and the content of P 5'N- I . The count of the stippling cell was varied in the family. Conclusion.- One of the reasons for congenital P5' N- I deficiency might be the deficiency in the enzyme content. The morphology of peripheral blood erythrocyte may be an assistant diagnotic index. The P5'N- I activities and contents were measured simultaneously may be a effective method in clinic diagnosis.     

Therapeutic effect of 5-FC on YCD modified murine P388 leukemia in vivo

Cytosine deaminases (CDs) in bacteria andfungi are found to deaminate prodrug 5 - FC intocytotoxic agent 5 - FU .Yeast CD (YCD) is clonedfrom Saccharomyces cerevisiae.It has been shownpreviously that YCD was more efficient inconversing5 - FC than bacterial CD(b CD) [1-3 ] .As anovel suicide gene therapy system,YCD/ 5 - Fcsystem may be promising in cancer therapy andprevention of graft versus host disease.In thepresent study,we established a P388/ DBA murineleukemia model by infusin…     

地高辛临床药物动力学参数的预测及个体化给药方案

用Bayesian一点法拟合心衰病人的DG个体药物动力学参数及个体化给药方案,用minitab对软件DG群体药物动力学数据进行统计学分析.以CrCL为固定效应变量,建立系列回归模型,预测心衰病人的DG个体药物动力学参数、个体化给药方案及其对映的(?)ss.结果显示CrCL与DG群体药物动力学参数存在高度的相关(P<0.001),相关系数分别为:CL=0.805,Vd=0.985,T_(1/2)=-0.517,K=0.525,D_(1.0)=0.714.并建立定量回归模型,预测DG个体药物动力学参数,预测参数与实测参数没有统计学差异,其中以Vd预测精度最好,有95%的预测值在实测值的95%置信限以内.与实测值相关系数为0.974,估计标准误差小于3.3%;其次是CL,有2/3的预测值在实测值95%置信限以内,与实测值相关系数为0.797,估计标准误差小于20%;T_(1/2)和K预测结果稍差.CrCL预测的个体化给药方案80%符合最佳个体化给药方案,且两者所对应的(?)ss没有显著性差异.     

冠心病患者血脂异常与胰岛素抵抗的关系

目的 :探讨冠心病患者血脂异常与胰岛素抵抗的关系。方法 :观察 68例冠心病患者与 66例对照者的血脂、血糖、胰岛素等生化指标 ,以胰岛素释放指数———空腹胰岛素 (FIns) /空腹血糖 (FBG)和胰岛素敏感指数(1 /FBG×FIns)作为胰岛素抵抗 (IR)的指标 ,与空腹血脂进行直线相关分析。结果 :冠心病组与对照组对比 ,血糖水平无明显差异 (P >0 .0 5) ,而血胰岛素、胰岛素释放指数明显较对照组增高 (P <0 .0 5) ,胰岛素敏感指数明显较对照组低 (P <0 .0 5)。冠心病组的甘油三酯 (TG)、总胆固醇 (TC)、低密度脂蛋白胆固醇 (LDL -C)明显较对照组增高 (P <0 .0 5)、高密度脂蛋白胆固醇 (HDL -C)明显较对照组低 (P <0 .0 5)。冠心病组胰岛素释放指数、胰岛素敏感指数分别与TG ,TC和LDL -C呈正相关 ,与HDL -C呈负相关。结论 :冠心病患者存在着高胰岛素血症和胰岛素抵抗 ,而且冠心病患者的胰岛素抵抗和血脂异常密切相关。
