简介：目的中国汉族人群中SCN5A基因A1673G多态与孤立阵发房颤的相关性。方法选取汉族孤立阵发房颤患者120例为观察组,以健康汉族人群120例为对照组,采用限制性片段长度多态性分析（RFLP）,对SCN5A基因A1673G的多态位点进行基因型鉴定,并随机挑选样本进行测序,检验其可靠性。结果SCN5A基因A1673G多态位点在中国汉族人群孤立阵发房颤患者和正常组比较,基因型频率符合Hardy-Weinberg平衡定律;A1673G多态的基因型频率在两组间差异有统计学意义（P〈0.05）,房颤患者G等位基因高于正常组;GG基因型对房颤患者有明显影响（P〈0.05）。结论SCN5A基因变异可能与中国汉族人群孤立阵发性房颤相关。

简介：花生作为老百姓喜爱的传统食品之一,自古以来就有＂长生果＂的美誉。民谚道＂：常吃花生能养生＂,研究发现,其具有一定的药用价值和保健功能。1、降低胆固醇花生性味甘、平,可健脾和胃、润肺化痰、益气止血,用于脾虚消瘦、食少乏力、干咳少痰、产后乳汁不足等症。李教授介绍说,花生中的脂肪可使肝内胆固醇分解为胆汁酸,促进排泄,从而降低血中胆固醇含量,用以预防动脉粥样硬化。

简介：大多时候,期刊将注意力集中在已适用于治疗心脏病患者的治疗方法上。这篇文章却不一样。主编选了5个有关心血管健康的创新型科技,他预测我们会在接下来的几年里经常听到这些科技。诊断、治疗心脏病的创新设备和手术即将来临。1.谷歌眼镜众所周知的可佩戴计算技术——谷歌眼镜,是一款头戴式眼镜。这款复杂的微型计算机可以拍照,录制视频,无线传输数据。医生可以在进行医疗手术时,使用无手操作装置,录制和传输图片，不需要操作照相机，也不会弄脏无菌外科手术环境。

简介：随着支架植入技术的进步,越来越多的多支病变及左主干病变的患者选择植入支架的治疗策略而非外科搭桥,但是对于这类患者中外科搭桥与介入治疗孰优孰劣的争议却从未停止。近日发表于JACC杂志的一项大型研究纳入了多项随机对照研究的数据,分析发现,选择介入治疗的患者5年内发生卒中的风险要远低于选择外科搭桥的患者。该研究纳入了来自11项对比PCI和外科搭桥的随机对照试验的数据,共计11518例受试者(PCI:n=5753,CABG:n=5765),平均随访时间3.8年,发生了239例卒中。
