Zhongguo shiyan zhenduanxue, 2015 急性心肌梗死（AMI）是临床常见的急、危、重病,诊断依赖于临床胸痛症状,心电图的改变和心肌损伤标志物升高,本文通过实验证实心肌肌钙蛋白I和肌钙蛋白T在AMI的早期诊断中具有较高灵敏度和较强特异性。可取代CK-MB作为心肌损伤新的"金标准",较好地用于AMI的早期诊断与鉴别,促进患者的康复。我们收集临床心肌梗死患者68例,并检测血清肌钙蛋白和肌酸激酶同工酶水平,探讨其在急性心肌梗死患者诊断中的临床价值。

Zhongguo shiyan zhenduanxue, 2012 目的研究微小RNA（microRNA,简称miRNA）与心肌细胞氧化应激的关系,作为探讨缺血再灌注损伤分子病理生理的基础。方法培养中的H9c2（2-1）心肌细胞以过氧化氢处理产生氧化应激,然后收集心肌细胞提取miRNA。选取miR-210和miR-24进行逆转录,再进行定量实时聚合酶链式反应。结果心肌细胞以过氧化氢处理2h后,与对照相比,miR-210显著降低至对照水平的47.07%（P=0.013）,而miR-24的水平则大幅升高,达到了对照水平的344.48%（P=0.002）。结论 ...
