  目的:评价临床标本对于Beckman Unicel DxI800 Access化学发光免疫分析仪试剂盒beckman coulter access total β-HCG更新换代升级为beckman coulter access total β-HCG(5th IS)试剂盒进行比对,检测效能评估.方法:依照美国临床实验室标准化协会(CLSI) EP9-A2文件,两种试剂分别对88例血清标本进行测定,并应用SPSS19.0对结果进行配对T检验.结果:与beckman coulter access total β-HCG试剂盒相比,beckman coulter access total β-HCG(5th IS)试剂盒的检测结果显著升高(107±14 mIU/ml vs140±18mIU/ml),测定结果的差异有统计学意义(P<0.05).结论:新代试剂盒比之前老试剂盒灵敏度更高.当实验室内同一检测项目试剂盒升级后除了更换厂家提供的试剂盒参考范围值,可有效地降低试剂换代升级后对临床诊疗上的干扰.

目的:了解外周血小板计数增高对结核病患者病情的诊治价值.方法:选择2013年1月至2015年12月住院初治骨结核进展期92例、治疗后好转期47例及同期健康体检者60例.采用血常规细胞计数仪检测外周血白细胞、血小板计数、中性粒细胞比值;同日送检血红细胞沉降率(ESR)及C反应蛋白(CRP).SPSS13.0统计软件处理数据.结果:进展期ESR及CRP分别明显高于好转期组(P<0.005,P<0.00
论文目的:血小板在血栓形成和止血中起着关键的作用。论文方法:静息状态下的血小板在血管损伤时,会与细胞外基质相互作用,从而发生血小板的黏附、活化和聚集,并最终形成血栓。然而最近,有人提出新的有关血小板在血管生成中的作用机制。血小板中的α颗粒存有促进和抑制血管生成的蛋白。血小板的活化促进了它们的释放,引发一系列血管生成的反应。同时,血小板源性的磷脂和微粒也同样能在血管生成中起到协同作用。因此,血小板在
