目的 探讨血清中性粒细胞明胶酶相关脂质运载蛋白(NGAL)、基质金属蛋白酶-28(MMP-28)在老年急性ST段抬高型心肌梗死(ASTEMI)患者中的表达及临床意义.方法 选取2017年1月至2019年1月在我科接受PCI治疗的老年ASTEMI患者150例(观察组),根据患者随访期间有无MACE发生,分为MACE发生组(n=50)和无MACE发生组(n=100).同期另选我院老年健康体检者100例(对照组).检测并比较各组血清NGAL、MMP-28水平.应用ROC曲线分析血清NGAL、MMP-28对老年ASTEMI患者预后的预测价值,并以多因素Logistic回归分析影响患者预后的危险因素.结果 观察组血清NGAL、MMP-28水平高于对照组,MACE发生组患者血清NGAL、MMP-28水平高于无MACE发生组,差异均具有统计学意义(P<0.05).Pearson相关性分析示:血清NGAL、MMP-28与LVEF呈负相关,与Gensini评分呈正相关(均P<0.05).血清NGAL、MMP-28预测老年ASTEMI患者不良预后的曲线下面积为0.837、0.872,灵敏度、特异性分别为(0.786和0.794)、(0.804和0.765).多因素Logistic回归分析显示,血清NGAL、MMP-28升高是影响老年ASTEMI患者不良预后的独立危险因素(P<0.05).结论 血清NGAL、MMP-28水平与老年ASTEMI患者PCI术后患者预后密切相关,是影响患者预后的重要危险因素,联合检测血清NGAL、MMP-28对老年ASTEMI患者预后评估的有较高预测价值.

目的:观察简化手指操对经桡动脉行冠状动脉造影术(CAG)的病人术后发生桡动脉闭塞及肢体麻木疼痛、肿胀情况的干预效果.方法:选取经桡动脉行CAG的326例病人,随机分为观察组(n=163)接受常规护理和简化手指操干预,对照组(n=163)仅接受常规护理,观察2组病人术后的手掌周径、麻木疼痛程度及术后24 h、30 d桡动脉闭塞发生率.结果:观察组病人术后术肢疼痛麻木程度及肿胀程度均低于对照组(P<0.05～P<0.01).观察组术后24 h桡动脉闭塞发生率低于对照组(P0.05).结论:简化手指操可减少经桡
