Involvement of Abnormal MicroRNA Expression in the Mechanism of Drug Resistance with Acute Myeloid Leukemia [PDF]
, 2016 目的：分析miRNA-98的表达异常在急性髓系白血病化疗耐药机制的作用，通过靶向过表达miRNA-98的表达水平探讨以miRNA-98为靶点增加化疗药物敏感性的可能性并分析其可能作用的机制。评价异常表达的血清miRNA-155是否可作为急性髓系白血病的预后标志。 方法：离体实验中，采用qRT-PCR方法检测K562和其耐药株K562/A02中miR-98、E2F1基因表达情况。通过瞬时转染miR-98mimic处理耐药细胞K562/A0248h后，通过qRT-PCR法检测miR-98表达情况；通过qRT-

hs-cTnT和NT-proBNP在急性心肌梗死患者预后中的价值研究
Zhongguo shiyan zhenduanxue, 2016 目的探索hs-cTnT和NT-proBNP在急性心肌梗死患者预后中的临床价值。方法纳入2013年1月至2014年12月共347例AMI患者为研究对象,按预后分为预后良好组（272例）和预后不良组（75例）。比较两组患者hs-cTnT和NT-proBNP水平,分析预后良好组和预后不良组入院及出院hs-cTnT和NT-proBNP水平差异。结果在预后不良组中出院hs-cTnT水平为3127.0（1638.0-6054.0）ng/L,高于入院hs-cTnT的1390.0（291.7-4189.0）ng/L ...
