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

国际脑血管病杂志 2014年第5期22卷 325-364页

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.

The first search for the doubly heavyΩ^(0)_(bc)baryon and a search for the E^(0)_(bc)baryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb^(-1).The baryons are reconstructed via their decays to Λ^(+)_(c)π^(-)and E^(+)_(c)π^(-).No significant excess is fbund for invariant masses between 6700 and 7300 MeV/c^(2),in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on the ratio of the Ω^(0)_(bc)and E^(0)_(bc)production cross-section times the branching fraction to Λ^(+)_(c)π^(-)(E^(+)_(c)π^(-))relative to that of the Λ^(0)_(b)(E^(0)_(b))baryon,for different lifetime hypotheses,at 95%confidence *** upper limits range from 0.5 x 10^(-4)to 2.5 x 10^(-4)for theΩ^(0)_(bc)→Λ^(+)_(c)π^(-)(E^(0)_(bc)→Λ^(+)_(c)π^(-))decay,and from 1.4x 10^(-3)to 6.9 x 10^(-3)for theΩ^(0)_(bc)→E^(+)_(c)π^(-)(E^(0)_(bc)→E^(+)_(c)π^(-))decay,depending on the considered mass and lifetime of theΩ^(0)_(bc)(E^(0)_(bc))baryon.

A first search for the Ξ_(bc)^(+)J/ψΞ_(c)^(+) decay is performed by the LHCb experiment with a data sample of proton-proton collisions, corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7, 8, and 13 TeV. Two peaking structures are seen with a local (global) significance of 4.3(2.8) and 4.1(2.4) standard deviations at masses of 6571 and 6694 MeV/c2, respectively. Upper limits are set on the Ξ+bc baryon production cross-section times the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-mass energies of 8 and 13 TeV, in the Ξ+bc and in the B+c rapidity and transverse-momentum ranges from 2.0 to 4.5 and 0 to 20geV/c, respectively. Upper limits are presented as a function of the Ξ+bc mass and lifetime.

近日。来自麻省总医院、博德研究所及哈佛大学的研究人员通过联合研究，在单细胞水平上对脑瘤基因组进行了分析。他们发现。癌症干细胞或许能够诱发少突神经胶质瘤的发生，少突神经胶质瘤是一种缓慢发展但却非常难以治愈的脑癌，相关研究刊登于Nature杂志上。同时研究者还首次在人类脑瘤样本中鉴别出了癌症干细胞及其分化的后代细胞。
