| 1 | Caspase-3 activation as a bifurcation point between plasticity and cell death显示文摘Death-mediating proteases such as caspases and caspase-3 in particular,have been implicated in neurodegenerative processes,aging and Alzheimer's disease.However,emerging evidence suggests that in addition to their classical role in cell death,caspases play a key role in modulating synaptic function.It is remarkable that active caspases-3,which can trigger widespread damage and degeneration,aggregates in structures as delicate as synapses and persists in neurons without causing acute cell death.Here,we evaluate this dichotomy,and discuss the hypothesis that caspase-3 may be a bifurcation point in cellular signaling,able to orient the neuronal response to stress down either pathological/apoptotic pathways or towards physiological cellular remodeling.We propose that temporal,spatial and other regulators of caspase activity are key determinants of the ultimate effect of caspase-3 activation in neurons.This concept has implications for differential roles of caspase-3 activation across the lifespan.Specifically,we propose that limited caspase-3 activation is critical for synaptic function in the healthy adult brain while chronic activation is involved in degenerative processes in the aging brain. | Shikha Snigdha Erica D Smith G Aleph Prieto Carl W Cotman | 2012 | Neuroscience Bulletin2012，28，1： | 91 |
| 2 | 急性缺血性卒中静脉阿替普酶溶栓治疗的纳入和排除标准的科学依据美国心脏协会/美国卒中协会对医疗卫生专业人员发布的声明(续前)显示文摘19 颅内出血史
根据最初的 FDA 标签和2013年AHA/ASA指南,颅内出血史是静脉阿替普酶治疗缺血性卒中的一项额外禁忌证或排除标准。最近修订后的标签仅将近期 ICH 列为一项警告,并且在禁忌证中删除了ICH史。与前面讨论的静脉阿替普酶治疗排除标准相似,文献回顾仅在大样本回顾性研究中发现了少量这类病例。缺乏相关数据可能是修订后的FDA 标签不再将 ICH 史作为禁忌证而仅将近期ICH 列为一项警告的原因。在这种情况下,FDA 如何定义“近期”一词尚不清楚。有趣的是,对在静脉阿替普酶治疗前通过 MRI 检测脑微出血( cerebral microbleed, CMBs)存在情况进行的研究可为这个卒中亚组患者提供更多的见解。从病理生理学角度,这种微出血的原因尚不清楚,可能反映再灌注损伤或脑血管自动调节功能破坏。因此,在静脉阿替普酶治疗后出现这些损害可能没有意义或是人为信号。 | Dawn O.

| 5 | 关于中国土壤碳库及固碳潜力研究的若干问题显示文摘土壤碳库研究及碳汇问题是近年来土壤碳循环与全球变化研究的热点领域.本文回顾了中国土壤碳库估算的研究成果,分析了我国土壤碳库在气候变化下的演变态势,并探讨了土壤有机碳矿化与温室气体的释放问题.整合已有的研究资料,可以认为中国土壤总有机碳库接近90Pg,无机碳库约为60Pg,农田土壤已有的固碳速率在20~25Tg/a水平.农田土壤固碳的理论容量可以达到2.0Pg水平,但农业技术的实施能够实现的技术潜力可能仅为理论潜力的1/3左右.因此,改善土壤管理和农田经营机制可能是提高土壤固碳技术潜力的关键.土壤固碳中有机碳积累并不表现出分解的敏感性,固碳显得有利于提高农田生产力和改善生态系统功能,一些农田综合温室气体排放的生命周期评价的案例研究反而显示有机质积累下农业生产的碳排放强度没有提高甚而降低.未来中国土壤碳库研究的重点发展方向在于:(1)以流域为尺度和地球表层系统为对象的系统固碳与碳汇研究;(2)生态系统土壤碳固定与稳定机制,特别是土壤固碳与生产力和生态服务功能的协同机理和多界面过程.中国土壤碳科学将面临多学科集成和多目标服务的新发展机遇. | 郑聚锋 程琨 潘根兴 SMITH Pete 李恋卿 张旭辉 郑金伟 韩晓君 杜彦玲 | 2011 | 科学通报2011，56，26： | 52 |
| 6 | 哪些凝血标志物可以增加传统危险因素对冠心病和缺血性中风的预测价值?Caerphilly研究显示文摘背景:目前鲜有研究证实,凝血标志物是否可以独立于传统危险因素与患冠心病和缺血性中风相关。本研究对11个反映凝血过程不同方面的标志物进行研究,以期发现在排除传统危险因素的作用之后,它们是否仍有预测价值。
方法与结果:在1984~1988年间,共2398名49~65岁男子接受检查,他们中大部分人采取了空腹血测定血脂和凝血标志物。对他们进行了平均13年的随访,记录了心血管事件(cardiovascular disease,CVD)发生情况。共发生486起心血管事件,353起新发生冠心病,133起新发生缺血性中风。经单变量分析,发现纤维蛋白原、低活化蛋白C值、D-二聚体、组织性纤溶酶原(tPA)、纤溶酶原激活物抑制物-1(PAI-1)都显著与CVD相关。将传统危险因素引入比例风险模型后,采用多变量分析方法,发现纤维蛋白原、D-二聚体、纤溶酶原激活物抑制物-1都显著与CVD相关,并且因子VIIc呈负相关(P=0.001)。在纳入传统危险因素的模型中,预先不存在CVD者,若具有预期风险构成最高3种的危险因素,则其发生CVD的风险是具有最低3位者的2.7倍。当模型包括4个凝血相关因素时,此值升至3.7倍。
结论:除传统的危险因素外,纤维蛋白原、D-二聚体、纤溶酶原激活物抑制物-1活性、因子VIIc均有预测中年男性的冠心病\缺血性中风发生的作用。 | Smith A 秦春常 | 2005 | 中国分子心脏病学杂志2005，5，6： | 43 |
| 7 | 美国临床肿瘤学会IV期非小细胞肺癌化疗的临床实践指南更新显示文摘本文旨在为IV期非小细胞肺癌患者的治疗提供更新版推荐。本文资料检索源自2002年以来公布的相关随机试验文献。此指南范围限于化疗与生物治疗。更新委员会对这些文献进行了总结并提供了推荐更新。162篇文献符合标准被纳入参考。本推荐基于可改善总生存期的治疗方法。仅改善无进展生存期的治疗方法推动了对毒性及生存质量的监测。对于体力状态评分为0分或1分患者的一线治疗,可推荐以铂类为基础的细胞毒性药物的两药联用。对铂类治疗有禁忌的患者,可采用非铂类细胞毒性两药联合。对于体力状态评分为2分的患者,单一细胞毒性药物即可。对于疾病进展或经过4个周期的治疗仍对治疗无反应的患者,应停止一线细胞毒性化疗。即使在6个周期后患者对治疗仍有反应,亦应停止两药细胞毒性化疗。对于伴有明确的表皮生长因子受体(epidermal growth factor receptor,EGFR)突变的患者,可推荐一线采用吉非替尼治疗;对于EGFR突变为阴性或不明确的患者,细胞毒性化疗更佳。除具有特定临床特征的患者外,可推荐贝伐单抗与卡铂-紫杉醇联用。对于通过免疫组化证实EGFR阳性的肿瘤患者,可推荐西妥昔单抗与顺铂-长春瑞滨联用。多西紫杉醇、厄洛替尼、吉非替尼或培美曲塞被推荐作为二线治疗。对于未曾接受过厄洛替尼或吉非替尼治疗的患者,可推荐厄洛替尼作为三线治疗。现有数据不足以推荐常规三线采用细胞毒性药物。已有的证据也不足以推荐常规应用分子标记物选择化疗。 | Christopher G.

| 10 | 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.

| 15 | Antimicrobial susceptibility testing for Helicobacter pylori in times of increasing antibiotic resistance显示文摘The gram-negative bacterium Helicobacter pylori(H.pylori)causes chronic gastritis,gastric and duodenal ulcers,gastric cancer and mucosa-associated lymphoid tissue lymphoma.Treatment is recommended in all symptomatic patients.The current treatment options for H.pylori infection are outlined in this review in light of the recent challenges in eradication success,largely due to the rapid emergence of antibiotic resistant strains of H.pylori.Antibiotic resistance is a constantly evolving process and numerous studies have shown that the prevalence of H.pylori antibiotic resistance varies significantly from country to country,and even between regions within the same country.In addition,recent data has shown that previous antibiotic use is associated with harbouring antibiotic resistant H.pylori.Local surveillance of antibiotic resistance is warranted to guide clinicians in their choice of therapy.Antimicrobial resistance is assessed by H.pylori culture and antimicrobial susceptibility testing.Recently developed molecular tests offer an attractive alternative to culture and allow for the rapid molecular genetic identification of H.pylori and resistance-associated mutations directly from biopsy samples or bacterial culture material.Accumulating evidence indicates that surveillance of antimicrobial resistance by susceptibility testing is feasible and necessary to inform clinicians in their choice of therapy for management of H.pylori infection. | Sinéad M Smith Colm O’Morain Deirdre McNamara | 2014 | World Journal of Gastroenterology2014，20，29： | 40 |

| 18 | Synthesis, properties, and applications of graphene oxide/reduced graphene oxide and their nanocomposites显示文摘Thanks to their remarkable mechanical, electrical, thermal, and barrier properties, graphene-based nanocomposites have been a hot area of research in the past decade. Because of their simple top-down synthesis, graphene oxide (GO) and reduced graphene oxide (rGO) have opened new possibilities for gas barrier, membrane separation, and stimuli-response characteristics in nanocomposites. Herein, we review the synthesis techniques most commonly used to produce these graphene derivatives, discuss how synthesis affects their key material properties, and highlight some examples of nanocomposites with unique and impressive properties. We specifically highlight their performances in separation applications, stimuli-responsive materials, anti-corrosion coatings, and energy storage. Finally, we discuss the outlook and remaining challenges in the field of practical industrial-scale production and use of graphene-derivative-based polymer nanocomposites. | Andrew T.

| 20 | Phylogenetic reconstruction of Chirita and allies (Gesneriaceae) with taxonomic treatments显示文摘Chirita D. Don, a large genus in the subfamily Cyrtandroideae of Gesneriaceae, has been the subject of much debate whether it is a natural group or not. In addition, the highly heterogeneous Chirita has also been very problematic with regard to delimitation and subdivision. Here we used the nrDNA internal transcribed spacer and cpDNA trnL-F for molecular phylogenetic analaysis, combined with morphological data. Our results suggest that Chirita is an artificial, polyphyletic genus. The most important character that defines Chirita, the dorso-ventrally oblique and bilamellar stigma, has evolved convergently in different clades of diandrous Cyrtandroideae. Chirita sensu stricto only includes the species of Chirita sect. Chirita, whereas Chirita sect. Microchirita is an independent clade located at the basal node of the phylogenetic tree. Chirita sect. Liebigia is closely related to Didymocarpus with an entire stigma unlike other species of Chirita. The species of Chirita sect. Gibbosaccus, Chiritopsis, Primulina, and Wentsaiboea form a monophyletic group that is sister to a strongly supported clade comprising four monotypic genera Paralagarosolen, Calcareoboea, Petrocodon, and Tengia. We further analyzed the morphological evolution of Chirita and identified a series of morphological synapomorphies for the monophyletic groups revealed herein, and thereby provide a taxonomic treatment in this study. | Yin-Zheng WANG Ru-Bing MAO Yan LIU Jia-Mei LI Yang DONG Zhen-Yu LI James E SMITH | 2011 | Journal of Systematics and Evolution2011，49，1： | 30 |
