1极高强度他汀治疗对冠状动脉粥样硬化消退的影响——ASTEROID试验显示文摘背景:以前的血管内超声(intravascular ultrasound,IVUS)试验证实,他汀治疗可减缓或阻止动脉粥样硬化的进展,但是迄今尚无应用动脉粥样斑块体积百分比(percent atheroma volume,PAV)证实粥样硬化消退的确切证据。PAV是最严格的评价病变进展和消退的IVUS测量指标。 目标:评价极高强度他汀治疗是否能逆转IVUS确定的冠状动脉粥样硬化。 设计和地点:于美国、加拿大、欧洲和澳大利亚53个社区和3级保健中心进行前瞻性开标盲法终点试验(A Study to Evaluate the Effect of Rosuvastatin on Intravascular Ultrasound-Derived Coronary Atheroma Burden,ASTEROID)。应用马达驱动回撤IVUS评价基线和治疗24个月时冠状动脉粥样斑块负荷。每对基线和随访IVUS测量结果均进行盲法分析。 病例:从2002年11月到2003年10月,507例患者有基线IVUS检查结果,并接受至少1个剂量的研究药物。在24个月后,349例患者具有可用于评估的系列IVUS检查结果。 干预:所有患者均接受瑞舒伐他汀40ms/d强化治疗。 主要观测指标:预先设定了两个一级疗效指标:PAV变化和基线最严重病变10min节段动脉粥样斑块体积变化。二级疗效指标为整个动脉标准化总斑块体积的变化。结果:平均(SD)LDL—C水平由基线时的130.4(34.3)ms/dL降至60.8(20.0)ms/扎,平均下降了53.2%(P〈0.001)。平均(SD)HDL-C水平从基线时的43.1(11.1)ms/dL升至49.0(12.6)ms/dL,平均增加了14.7%(P〈0.001)。整个血管PAV平均(SD)变化为-0.98%(3.15%),中位数为-0.79%(97.5%CI,-1.21%~-0.53%)(与基线比较,P〈0.001)。最严重病变10min节段斑块体积平均(SD)变化为-6.1(10.1)mm^3,中位数为-5.6mm^3(97.5%CI,-6.8~-4.0mm^3)(与基线比较,P〈0.001)。总斑块体积变化中位数降低了6.8%,平均减少了-14.7(25.7)mm^3,中位数为-12.5mm^3(95%CI,-15.1~-10.5mm^3)(与基线比较,P〈0.001)。不良事件少见,与其他他汀试验相似。 结论:应用瑞舒伐他汀40ms/d进行极高强度他汀治疗可使LDL-C平均水平达到60.8ms/dL,使HDL—C增加14.7%。这导致所有3个预先设定的IVUS斑块负荷指标均显示动脉粥样硬化消退。因此,将LDL-C降至低于目前指南规定的水平,同时显著提高HDL-C,可以使冠心病患者动脉粥样硬化斑块消退。这些变化对临床预后的影响尚需进一步研究确定。Steven E.

7印度支那地块第三纪构造滑移与青藏高原岩石圈构造演化显示文摘印度支那地块于早第三纪至中新世发生大规模地向东南方向走滑,同时伴随着15°顺时针旋转。青藏高原及邻区晚自垩世以来的古地磁古构造及地质年代学研究新成果,说明青藏高原岩石圈的构造演化过程,即古新世初印度板块与欧亚大陆的南缘拉萨地块碰撞,至49 Ma左右印度与拉萨地块发生全面拼合,随着印度板块进一步向北挤压,从碰撞期至16 Ma,印度支那地块沿红河大型走滑断裂发生侧向滑移;印度与“欧亚大陆”之间的构造缩短通过岩右圈板块沿着大型走滑断裂系的挤出以及板块间的消减得到调整。青藏高原大规模的岩石圈构造缩短很可能始于中新世27 Ma左右沿着早期陆块间的接合带发生。一些事实还说明青藏高原的总体隆起很可能是通过10 Ma前后和3 Ma以后多期非均匀隆升形成的。杨振宇 Jean Besse 孙知明 赵越 1998地质学报1998,72,2:39
8一种飞机图像目标多特征信息融合识别方法显示文摘提出了一种基于概率神经网络(Probabilistic neural networks,PNN)和DSmT推理(Dezert-Smarandache theory)的飞机图像目标多特征融合识别算法.针对提取的多个图像特征量,利用数据融合的思想对来自图像目标各个特征量提供的信息进行融合处理.首先,对图像进行二值化预处理,并提取Hu矩、归一化转动惯量、仿射不变矩、轮廓离散化参数和奇异值特征5个特征量;其次,针对DSmT理论中信度赋值构造困难的问题,利用PNN网络,构造目标识别率矩阵,通过目标识别率矩阵对证据源进行信度赋值;然后,用DSmT组合规则在决策级层进行融合,从而完成对飞机目标的识别;最后,在目标图像小畸变情形下,将本文提出的图像多特征信息融合方法和单一特征方法进行了对比测试实验,结果表明本文方法在同等条件下正确识别率得到了很大提高,同时达到实时性要求,而且具有有效拒判能力和目标图像尺寸不敏感性.即使在大畸变情况下,识别率也能达到89.3%.李新德 杨伟东 DEZERT Jean 2012自动化学报2012,38,8:32
9有限元分析法确定Johson-Cook本构方程材料参数显示文摘采用反演法确定了马氏体不锈钢410的Johnson-Cook本构方程材料参数.剪切实验采用的剪切速率为1~5000s-1,温度为20~1000℃.有限元模拟在Abaqus软件平台上进行.采用Johnson-Cook模型,施加与实验相同的初始条件.通过Matlab非线性最小二乘法优化程序来调整有限元模型材料参数,找到合适值,使得模拟得到的力-位移曲线与实验得到曲线相吻合.结果表明,所得参数都能很好地代表不锈钢410在高温高变形速度下的流动特性,Johnson-Cook模型不能描述材料破坏阶段的行为特征.董菲 Guenael Germain Jean Lou Lebrun 李铸国 2011上海交通大学学报2011,45,11:30

12A Comparison of Carlin-type Gold Deposits:Guizhou Province,Golden Triangle,Southwest China,and Northern Nevada,USA显示文摘Several Au deposits in Guizhou Province,southwest China,described as being similar to the highly productive Carlin-type gold deposits in northern Nevada.USA,were examined to identify similarities and differences between the two districts.Samples were collected along transects from lowto high-grade rock,where possible,and fram stockpiles at the Shuiyindong,Zimudang,Taipingdong,Yata and Jinfeng(formerly Lannigou)deposits.Methods used to examine ore and alteration minerals included hand-sample description:reflectance spectroscopy using an ASD Terraspec spectrometer;analyses of hand samples by carbonate staining with Alizaren red and potassium ferricyanide;transmitted and reflected light petrography;chemical analyses,mineral identification,and imaging using a JEOL.JSM-5610 scanning electron microscope:and quantitative chemical analyses using a JEOL JXA-8900 electron probe microanalyzer.Geochemical analyses of hand samples for 52 elements were done by ALS Chemex.Results indicate both similarities and differences between the two districts.Both districts have similar geologic histories.and deposits at both locations appear to have formed as a result of similar tectonic events.though the district in southwest China lacks evidence of eoeval felsic igneous activity;however,the ore-stage minerals and the fluids that produced the minerals and deposits have some significant differences.The Nevada deposits were dominated by fluid-rock reaction in which host rock Fe was sulfidized to form Au-bearing pyrite.Although ore fluids sulfidized host rock Fe in the Cuizhou deposits.the timing of Fe metasomatism is unknown,so whether the deposits formed in response to sulfidation or pyritization is unclear.Fluid-rock reaction between an acidic,aqueous fluid and highly reactive calcareous rocks in Nevada caused extensive decarbonatization of host rocks,jasperoid replacemerit of carbonate minerals,and alteration of silty rock components to illite and kaolinite.In Guizhou,CO2-bearing ore fluids with temperatures and pressures approaching 100℃ and 500 bars greater than temperatures and pressures detemained for ore fluids in the Nevada deposits,deposited Aubearing pyrite.In examined Guizhou deposits these fluids carbonatized host rocks and farmed both replacement and open-space-filling ore.The fluids,which may have been immiscible,were sufficiently overpressured to fracture wall rocks and to create significant open space filled by vein quartz.While deposit architecture,tectonic setting,and host rocks in Guizhou are quite similar to northern Nevada,ore and alteration minerals suggest that ore-forming processes in examined Guizhou deposits have important similarities to processes associated with formation of orogenic Au systems.The Guizhou deposits display characteristics of both Carlin-type and orogenic systems,perhaps indicating formation at conditions somewhat intermediate to conditions for Carlin-type deposits and orogenic systems.Jean S.CLlNE John L.MUNTEAN Xuexiang GU Yong XIA 2013地学前缘2013,20,1:23
13Advances in immunotherapy for treatment of lung cancer显示文摘Different approaches for treating lung cancer have been developed over time, including chemotherapy, radiotherapy and targeted therapies against activating mutations. Lately, better understanding of the role of the immunological system in tumor control has opened multiple doors to implement different strategies to enhance immune response against cancer cells. It is known that tumor cells elude immune response by several mechanisms. The development of monoclonal antibodies against the checkpoint inhibitor programmed cell death protein 1(PD-1) and its ligand(PD-L1), on T cells, has led to high activity in cancer patients with long lasting responses. Nivolumab, an anti PD-1 inhibitor, has been recently approved for the treatment of squamous cell lung cancer patients, given the survival advantage demonstrated in a phase III trial. Pembrolizumab, another anti PD-1 antibody, has received FDA breakthrough therapy designation for treatment of non-small cell lung cancer(NSCLC), supported by data from a phase I trial. Clinical trials with anti PD-1/PD-L1 antibodies in NSCLC have demonstrated very good tolerability and activity, with response rates around 20% and a median duration of response of 18 months.Jean G.Bustamante Alvarez María González-Cao Niki Karachaliou Mariacarmela Santarpia Santiago Viteri Cristina Teixidó Rafael Rosell 2015Cancer Biology & Medicine2015,12,3:22
14Stagnant lids and mantle overturns:Implications for Archaean tectonics, magmagenesis,crustal growth, mantle evolution, and the start of plate tectonics显示文摘The lower plate is the dominant agent in modern convergent margins characterized by active subduction,as negatively buoyant oceanic lithosphere sinks into the asthenosphere under its own weight.This is a strong plate-driving force because the slab-pull force is transmitted through the stiff sub-oceanic lithospheric mantle.As geological and geochemical data seem inconsistent with the existence of modernstyle ridges and arcs in the Archaean,a periodically-destabilized stagnant-lid crust system is proposed instead.Stagnant-lid intervals may correspond to periods of layered mantle convection where efficient cooling was restricted to the upper mantle,perturbing Earth's heat generation/loss balance,eventually triggering mantle overturns.Archaean basalts were derived from fertile mantle in overturn upwelling zones(OUZOs),which were larger and longer-lived than post-Archaean plumes.Early cratons/continents probably formed above OUZOs as large volumes of basalt and komatiite were delivered for protracted periods,allowing basal crustal cannibalism,garnetiferous crustal restite delamination,and coupled development of continental crust and sub-continental lithospheric mantle.Periodic mixing and rehomogenization during overturns retarded development of isotopically depleted MORB(mid-ocean ridge basalt)mantle.Only after the start of true subduction did sequestration of subducted slabs at the coremantle boundary lead to the development of the depleted MORB mantle source.During Archaean mantle overturns,pre-existing continents located above OUZOs would be strongly reworked;whereas OUZOdistal continents would drift in response to mantle currents.The leading edge of drifting Archaean continents would be convergent margins characterized by terrane accretion,imbrication,subcretion and anatexis of unsubductable oceanic lithosphere.As Earth cooled and the background oceanic lithosphere became denser and stiffer,there would be an increasing probability that oceanic crustal segments could founder in an organized way,producing a gradual evolution of pre-subduction convergent margins into modern-style active subduction systems around 2.5 Ga.Plate tectonics today is constituted of:(1)a continental drift system that started in the Early Archaean,driven by deep mantle currents pressing against the Archaean-age sub-continental lithospheric mantle keels that underlie Archaean cratons;(2)a subduction-driven system that started near the end of the Archaean.Jean H.Bédard 2018Geoscience Frontiers2018,9,1:21
15Comparison between endoscopic sclerotherapy and band ligation for hemostasis of acute variceal bleeding显示文摘AIM:To compare band ligation(BL) with endoscopic sclerotherapy(SCL) in patients admitted to an emergency unit for esophageal variceal rupture. METHODS:A prospective,randomized,single-center study without crossover was conducted.After endoscopic diagnosis of esophageal variceal rupture,patients were randomized into groups for SCL or BL treatment.Sclerotherapy was performed by ethanolamine oleate intravascular injection both above and below the rupture point,with a maximum volume of 20 mL.For BL patients,banding at the rupture point was attempted,followed by ligation of all variceal tissue of the distal esophagus.Primary outcomes for both groups were initial failure of bleeding control(5 d) ,early re-bleeding(5 d to 6 wk),and complications,including mortality.From May 2005 to May 2007,100 patients with variceal bleeding were enrolled in thestudy:50 SCL and 50 BL patients.No differences between groups were observed across gender,age,ChildPugh status,presence of shock at admission,mean hemoglobin levels,and variceal size. RESULTS:No differences were found between groups for bleeding control,early re-bleeding rates,complications,or mortality.After 6 wk,36(80%) SCL and 33(77 %) EBL patients were alive and free of bleeding.A statistically significant association between Child-Pugh status and mortality was found,with 16%mortality in Child A and B patients and 84%mortality in Child C patients(P<0.001) . CONCLUSION:Despite the limited number of patients included,our results suggest that SCL and BL are equally efficient for the control of acute variceal bleeding.Gustavo Oliveira Luz Fauze Maluf-Filho Sérgio Eiji Matuguma Fábio Yuji Hondo Edson Ide Jeane Martins Melo Spencer Cheng Paulo Sakai 2011World Journal of Gastrointestinal Endoscopy2011,3,5:20

18Need of surveillance response systems to combat Ebola outbreaks and other emerging infectious diseases in African countries显示文摘There is growing concern in Sub-Saharan Africa about the spread of the Ebola virus disease(EVD),formerly known as Ebola haemorrhagic fever,and the public health burden that it ensues.Since 1976,there have been 885,343 suspected and laboratory confirmed cases of EVD and the disease has claimed 2,512 cases and 932 fatality in West Africa.There are certain requirements that must be met when responding to EVD outbreaks and this process could incur certain challenges.For the purposes of this paper,five have been identified:(i)the deficiency in the development and implementation of surveillance response systems against Ebola and others infectious disease outbreaks in Africa;(ii)the lack of education and knowledge resulting in an EVD outbreak triggering panic,anxiety,psychosocial trauma,isolation and dignity impounding,stigmatisation,community ostracism and resistance to associated socio-ecological and public health consequences;(iii)limited financial resources,human technical capacity and weak community and national health system operational plans for prevention and control responses,practices and management;(iv)inadequate leadership and coordination;and(v)the lack of development of new strategies,tools and approaches,such as improved diagnostics and novel therapies including vaccines which can assist in preventing,controlling and containing Ebola outbreaks as well as the spread of the disease.Hence,there is an urgent need to develop and implement an active early warning alert and surveillance response system for outbreak response and control of emerging infectious diseases.Understanding the unending risks of transmission dynamics and resurgence is essential in implementing rapid effective response interventions tailored to specific local settings and contexts.Therefore,the following actions are recommended:(i)national and regional inter-sectorial and trans-disciplinary surveillance response systems that include early warnings,as well as critical human resources development,must be quickly adopted by allied ministries and organisations in African countries in epidemic and pandemic responses;(ii)harnessing all stakeholders commitment and advocacy in sustained funding,collaboration,communication and networking including community participation to enhance a coordinated responses,as well as tracking and prompt case management to combat challenges;(iii)more research and development in new drug discovery and vaccines;and(iv)understanding the involvement of global health to promote the establishment of public health surveillance response systems with functions of early warning,as well as monitoring and evaluation in upholding research-action programmes and innovative interventions.Ernest Tambo Emmanuel Chidiebere Ugwu Jeane Yonkeu Ngogang 2014Infectious Diseases of Poverty2014,3,1:20
