1影响卒中死亡率下降的因素美国心脏协会/美国卒中协会的科学声明显示文摘背景和目的 美国的卒中死亡率自20世纪初以来一直呈下降趋势,尽管这种“下降”很受欢迎,但其原因尚不完全清楚.由于近年来卒中死亡率呈现出更为显著的加速下降趋势,卒中已从美国的第3位死亡原因下降至第4位.这促使人们对影响卒中发病风险和死亡率变化的相关因素进行详细评估.这份声明对有关卒中死亡率下降趋势的促进因素的研究证据进行回顾,并讨论了将来如何利用这些因素在卒中这一重大公共卫生问题的干预研究中发挥作用.方法 写作组成员由委员会主席和副主席根据其以前在相关领域的研究成果提名,并通过美国心脏协会(American Heart Association,AHA)卒中委员会的科学声明监督委员会和美国心脏协会手稿监督委员会批准.作者利用系统文献综述,参考公开发表的临床和流行病学研究、发病率和死亡率报告、临床与公共卫生指南、权威声明、个人文件以及专家意见,对相关证据进行总结并指出与当前知识水平的差距.所有写作组成员均有机会评论这份声明并批准其最终版本.这份声明经过AHA内部的广泛同行评议以及卒中委员会领导阶层和科学声明监督委员会的审查,然后获得AHA科学顾问与协调委员会的批准.结果 过去数十年间,在不同性别、所有种族/民族以及各个年龄组人群中都观察到卒中死亡率的下降,这体现出人群健康的重大进展.除了卒中对于总体寿命损失的影响减少外,在65岁以下人群中观察到的卒中死亡率显著下降体现了其所致潜在寿命损失年的减少.卒中死亡率的下降要归功于卒中发病率和病死率的降低.这些卒中转归的显著改善与心血管危险因素的控制和干预相一致.虽然很难计算出具体的归因危险度估计值,但始于20世纪70年代的血压控制措施似乎已对卒中死亡率的加速下降产生了最实质性的影响.尽管实施较晚,但糖尿病和血脂异常控制以及戒烟计划,特别是联合降压治疗,似乎同样促进了卒中死亡率的下降.远程医疗和卒中医疗体系也似乎具有强烈的潜在作用,但尚需足够长的时间来证明其对卒中死亡率下降的影响.其他因素也可能产生影响,但需要更多的研究来确定它们的作用.结论 卒中死亡率的下降是真实存在的,代表着公共卫生以及临床医学的巨大成功.卒中从第3位死亡原因下降至第4位是死亡率真实下降的结果,而并非由于慢性肺病死亡率上升所致,后者是目前在美国是第3位的死亡原因.有强烈的证据表明,卒中死亡率的下降可归功于以科学发现为基础、旨在降低卒中风险而执行的联合干预措施和项目,其中最有可能的是对高血压控制的改善.因此,对正在开展的干预项目进行的研究及其成果的应用已改善了人群健康.对一些积极的循证公共卫生项目以及临床干预措施的持续应用预期会进一步降低卒中死亡率.Daniel T.Lackland Edward J.Roccella Anne F.Deutsch Myriam Fornage Mary G.George George Howard Brett M.Kissela Steven J.Kittner Judith H.Lichtman Lynda D.

2A community-derived classification for extant lycophytes and ferns显示文摘发展史长通知了蕨类植物分类。当我们推断进化的树的能力改善了,针对认出生来的组的分类变得逐渐地预兆、稳定。这里,我们为 lycophytes 和蕨纲植物提供一个现代、全面分类,在下面,利用一条基于社区的途径类水平。我们 monophyly 用作主要标准让 taxa,而且目的识别保存两个广泛地被接受的存在 taxa 和界限并且与我们蕨类植物发展史的理解一致。总共,这个分类对待一在 337 个类, 51 个家庭, 14 目,和二个班估计了 11  916 种类。这个分类没在 lycophyte 和蕨纲植物上作为最后的词被打算分类,而是当前的假设的概括陈述,源于最好的可得到的数据并且在问题由熟悉植物的那些大多数塑造了。我们希望它将在蕨类植物上为最近的文学的那些想要的参考用作一个资源发展史和分类,为指导未来调查的一个框架,和推进讲话的刺激。Eric Schuettpelz Harald Schneider Alan R.

3GDNF-Enhanced Axonal Regeneration and Myelination Following Spinal Cord Injury is Mediated by Primary Effects on Neurons显示文摘我们先前研究表明胶质细胞源性神经营养因子(GDNF)联合施万细胞移植能促进脊髓损伤后轴突再生和髓鞘形成。然而,GDNF介导这一过程的细胞靶点尚不清楚。在此,我们报道了GDNF可增加在体再生轴突的数目和直径,并促进体外背根神经节神经元的轴突向外生长,提示GDNF对神经元有直接作用。在施万细胞-背根神经节神经元共培养下,GDNF显著增加施万细胞生成的髓鞘数目;GDNF处理对孤立培养的施万细胞增殖无作用,但可促进已与神经轴突有突触联系的施万细胞增殖;GDNF可增加孤立施万细胞中分子量为140kDa的神经细胞黏附分子(NCAM)的表达,但对黏附分子L1表达或神经营养因子NGF、NT3及BDNF分泌没有影响。总之,这些结果支持假设:GDNF提高轴突再生和施万细胞髓鞘形成主要是通过GDNF对神经元的直接作用介导的,并且提示GDNF联合施万细胞移植可能是促进脊髓损伤后轴突再生和髓鞘形成的有效策略之一。LIQUN ZHANG ZHENGWEN MA GEORGE M.

4miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium.Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey 2011World Journal of Gastroenterology2011,17,8:13
5Neuronal failure in Alzheimer's disease: a view through the oxidative stress looking-glass显示文摘Considerable debate and controversy surround the cause(s) of Alzheimer's disease(AD). To date, several theories have gained notoriety, however none is universally accepted. In this review, we provide evidence for the oxidative stress-induced AD cascade that posits aged mitochondria as the critical origin of neurodegeneration in AD.David J.

10Inhibition of hepatitis C virus replication by single-stranded RNA structural mimics显示文摘AIM: To examine the effect of hepatitis C virus (HCV) structural mimics of regulatory regions of the genome on HCV replication.METHODS: HCV RNA structural mimics were constructed and tested in a HCV genotype 1b aBB7 replicon,and a Japanese fulminant hepatitis-1 (JFH-1) HCV genotype 2a infection model.All sequences were computer-predicted to adopt stem-loop structures identical to the corresponding elements in full-length viral RNA.Huh7.5 cells bearing the BB7 replicon or infected with JFH-1 virus were transfected with expression vectors generating HCV mimics and controls.Cellular HCV RNA and protein levels were quantified by real-time polymerase chain reaction and Western blotting,respectively.To evaluate possible antisense effects,complementary RNAs spanning a mimic were prepared.RESULTS: In the BB7 genotype 1b replicon system,mimics of the polymerase (NS-5B),X and BA regions inhibited replication by more than 90%,50%,and 60%,respectively.In the JFH-1 genotype 2 infection system,mimics that were only 74% and 46% identical in sequence relative to the corresponding region in JFH-1 inhibited HCV replication by 91.5% and 91.2%,respectively,as effectively as a mimic with complete identity to HCV genotype 2a.The inhibitory effects were confirmed by NS3 protein levels.Antisense RNA molecules spanning the 74% identical mimic had no significant effects.CONCLUSION: HCV RNA structural mimics can inhibit HCV RNA replication in replicon and infectious HCV systems and do so independent of close sequence identity with the target.Robert Smolic Martina Smolic John H Andorfer Catherine H Wu Robert M Smith George Y Wu 2010World Journal of Gastroenterology2010,16,17:2
