  • 简介:那句熟悉的“吃蔬菜吧!”还没有过时。CDC最近一项报告指出,在美国,十个人中仅有一位的蔬菜摄入量达到了当前联邦膳食指南建议的摄入量,而人们的水果摄入情况也并不乐观(详见下文“你应该吃多少?”)。

  • 简介:高血压是致死、致残性疾病的重要危险因素之一,随机对照试验(RCT)证实降压能够有效改善患者的预后。美国JNC8高血压指南[1]系统回顾了RCT文献,制定出高血压管理的相关证据声明和推荐,并对降压起点、目标和药物进行了重大更新,明显不同于其他高血压指南。

  • 简介:“JNC8”给我国临床医生带来不少新的理念,但在高血压用药方面也带来一些困惑。JNC8是根据美国及欧洲RCT研究证据对JNC7中高血压用药方面进行部分修改,虽有参考价值,但不能直接搬来指导我国的临床实践,我国人群及用药特点和欧美国家有明显不同;诊治高血压仍应按我国高血压防治指南的标准进行。

  • 简介:急性大面积肺栓塞是开胸术后死亡主要原因之一,及时诊断和有效治疗可以明显减少病死率。急诊床旁心电图是术后患者最方便快捷的检查手段,认真分析心电图变化的特点对及早诊断大面积急性肺栓塞有一定的指导意义。我们对本院近4年来8例开胸术后明确诊断为急性大面积肺栓塞患者的心电图进行回顾性分析,来探讨心电图对急性大面积肺栓塞诊断的作用。

  • 简介:目的探讨冠心病患者血清炎症因子白介素-6(IL-6)、白介素-8(L-8)和肿瘤坏死因子(TNF)含量在冠心病发展过程中的意义。方法测定81例冠心病患者血清炎症因子IL-6、IL-8和TNF含量,观察冠心病患者冠脉狭窄程度与血清IL-6、IL-8及TNF含量变化的关系。结果40例冠脉重度狭窄者血清炎症因子IL-6、IL-8和TNF分别为(163.41±64.18)pg/ml、(0.41±0.11)ng/ml、(2.54±0.63)ng/ral,41例冠脉轻中度狭窄者血清炎症因子IL-6、IL-8和TNF分别为(97.05±27.29)pg/ml、(0.34±0.16)ng/ml、(1.86±0.33)ng/ml,两组间差异存在统计学意义(P〈0.05)。结论血清炎症因子IL-6、IL-8和TNF与冠心病的严重程度有关。冠脉狭窄越明显,炎症因子IL-6、IL-8及TNF含量越高。
