2Nano-Graphene Oxide for Cellular Imaging and Drug Delivery显示文摘Two-dimensional graphene offers interesting electronic,thermal,and mechanical properties that are currently being explored for advanced electronics,membranes,and composites.Here we synthesize and explore the biological applications of nano-graphene oxide(NGO),i.e.,single-layer graphene oxide sheets down to a few nanometers in lateral width.We develop functionalization chemistry in order to impart solubility and compatibility of NGO in biological environments.We obtain size separated pegylated NGO sheets that are soluble in buffers and serum without agglomeration.The NGO sheets are found to be photoluminescent in the visible and infrared regions.The intrinsic photoluminescence(PL)of NGO is used for live cell imaging in the near-infrared(NIR)with little background.We found that simple physisorption viaπ-stacking can be used for loading doxorubicin,a widely used cancer drug onto NGO functionalized with antibody for selective killing of cancer cells in vitro.Owing to its small size,intrinsic optical properties,large specifi c surface area,low cost,and useful non-covalent interactions with aromatic drug molecules,NGO is a promising new material for biological and medical applications.Xiaoming Sun Zhuang Liu Kevin Welsher Joshua Tucker Robinson Andrew Goodwin Sasa Zaric Hongjie Dai 2008Nano Research2008,1,3:118
3Hepatocellular carcinoma: Epidemiology, risk factors and pathogenesis显示文摘Hepatocellular carcinoma (HCC) is the commonest primary malignant cancer of the liver in the world. Given that the burden of chronic liver disease is expected to rise owing to increasing rates of alcoholism, hepatitis B and C prevalence and obesity-related fatty liver disease, it is expected that the incidence of HCC will also increase in the foreseeable future. This article summarizes the international epidemiology, the risk factors and the pathogenesis of HCC, including the roles of viral hepatitis, toxins, such as alcohol and aflatoxin, and insulin resistance.Asmaa Ibrahim Gomaa Shahid A Khan Mireille B Toledano Imam Waked Simon D Taylor- Robinson 2008World Journal of Gastroenterology2008,14,27:78

5Can Chinese Medicine Be Used for Prevention of Corona Virus Disease 2019 (COVID-19)? A Review of Historical Classics, Research Evidence and Current Prevention Programs显示文摘Objective:Since December 2019,an outbreak of corona virus disease 2019(COVID-19)occurred in Wuhan,and rapidly spread to almost all parts of China.This was followed by prevention programs recommending Chinese medicine(CM)for the prevention.In order to provide evidenee for CM recommendations,we reviewed ancient classics and human studies.Methods:Historical records on prevention and treatment of infections in CM classics,clinical evidence of CM on the prevention of severe acute respiratory syndrome(SARS)and H1N1 in flue nza,and CM preve ntion programs issued by health authorities in China since the COVID-19 outbreak were retrieved from differe nt databases and websites till 12 February,2020.Research evide nee in eluded data from clinical trials,cohort or other population studies using CM for preventing contagious respiratory virus diseases.Results:The use of CM to prevent epidemics of infectious diseases was traced back to ancient Chinese practice cited in Huangdi's Internal Classic(Huang Di Nei Jing)where preventive effects were recorded.There were 3 studies using CM for prevention of SARS and 4 studies for H1N1 influenza.None of the participants who took CM contracted SARS in the 3 studies.The infection rate of H1N1 in flue nza in the CM group was significantly lower than the non-CM group(relative risk 0.36,95%confidence interval 0.24-0.52;n=4).For prevention of COVID-19,23 provinces in China issued CM programs.The main principles of CM use were to tonify qi to protect from external pathoge ns,disperse wind and discharge heat,and resolve damp ness.The most frequently used herbs in eluded Radix astragali(Huangqi),Radix glycyrrhizae(Gancao),Radix saposhnikoviae(Fangfeng),Rhizoma Atractylodis Macrocephalae(Baizhu),Lonicerae Japonicae Flos(Jinyinhua),and Fructus forsythia(Lianqiao).Conclusions:Based on historical records and human evidenee of SARS and H1N1 influenza prevention,Chinese herbal formula could be an alternative approach for prevention of COVID-19 in high-risk population.Prospective,rigorous population studies are warranted to confirm the potential preventive effect of CM.LUO Hui TANG Qiao-ling SHANG Ya-xi LIANG Shi-bing YANG Ming Nicola Robinson LIU Jian-ping 2020Chinese Journal of Integrative Medicine2020,26,4:61

7构建灾害应对护理人员培训体系的研究与实践显示文摘随着社会经济的发展和城市现代化高速发展,灾害逐渐呈现大规模、长期化的趋势,导致影响和危害人类健康和生命的因素越来越多,影响着人们的健康生活和社会的发展。一年前,中国汶川发生了震惊世界的特大地震灾害,中国急救医疗服务体系经历了前所未有的考验。社会已愈来愈清楚地认识到救援医学工作中护理人员的角色和作用。2008年在日本兵库县成立的世界灾害护理学会(World Society of Disaster Nursing,WSDN)对加强灾害护理的重要性及其发展趋势给予高度重视。在国外,灾害护理在教育、研究与实践等领域发展较快,而在国内,近几年才开始出现一些把灾害护理纳入到课程设置和教学内容中的教学改革研究,介绍SARS、四川大地震以及国外的灾害救援工作中的体验和灾害培训干预研究等文献。但是,由于灾害护理刚刚起步,缺少可借鉴的经验,为此,本刊特邀请国内外有关救援医学专家和灾害护理教育与研究专家撰写稿件,以探讨今后灾害护理的发展方向。李春玉 Courtland Robinson 2009中国护理管理2009,9,5:36
8蛇绿岩型金刚石和铬铁矿深部成因显示文摘地球上的原生金刚石主要有3种产出类型,分别来自大陆克拉通下的深部地幔金伯利岩型金刚石、板块边界深俯冲变质岩中超高压变质型金刚石,和陨石坑中的陨石撞击型金刚石。在全球5个造山带的10处蛇绿岩的地幔橄榄岩或铬铁矿中均发现金刚石和其他超高压矿物的基础上,我们提出地球上一种新的天然金刚石产出类型,命名为蛇绿岩型金刚石。认为蛇绿岩型金刚石普遍存在于大洋岩石圈的地幔橄榄岩中,并提出蛇绿岩型金刚石和铬铁矿的深部成因模式。认为早期俯冲的地壳物质到达地幔过渡带(410~660km深度)后被肢解,加入到周围的强还原流体和熔体中,当熔融物质向上运移到地幔过渡带顶部,铬铁矿和周围的地幔岩石以及流体中的金刚石等深部矿物一并结晶,之后,携带金刚石的铬铁矿和地幔岩石被上涌的地幔柱带至浅部,经历了洋盆的拉张和俯冲阶段,最终在板块边缘就位。杨经绥 徐向珍 张仲明 戎合 李源 熊发挥 梁风华 刘钊 刘飞 李金阳 李兆丽 陈松永 郭国林 Paul ROBINSON 2013地球学报2013,34,6:31

10都兰花岗岩锆石SHRIMP定年及柴北缘超高压带花岗岩年代学格架显示文摘柴北缘超高压带东端都兰地区花岗岩锆石SHRIMP U-Pb定年结果表明,野马滩东岩体的年龄为(406.6±3.5)Ma,巴立给哈滩西岩体的年龄分别为(407.3±4.3)和(397±6)Ma,水文站北岩体的年龄分别为(404.5±4.0)和(397.0±3.7)Ma,水文站南岩体的年龄为(380.5±5.0)Ma,察察公麻岩体的年龄分别为(382.5±3.6)和(372.5±2.8)Ma.从年龄上看,这些花岗岩明显地分为两期:早期的为407-397 Ma,晚期的为383-373 Ma.它们主要为准铝质-弱过铝质的石英闪长岩、花岗闪长岩和二长花岗岩.岩石地球化学研究表明,大多数样品为钙碱性系列,少数样品为钙性或碱钙性系列,其中,早期花岗岩的87Sr/86Sr比值(0.7082-0.7110)和模式年龄(T2DM=1.41-1.90 Ga)高于晚期花岗岩(0.7072-0.7091,T2DM=1.07-1.38 Ga),但晚期花岗岩的εNd(t)值(0.6- -3.0)高于早期花岗岩(-3.2- -9.3),表明早期花岗岩可能起源于早中元古代的大陆壳;而晚期花岗岩起源于晚中元古代玄武质地壳.结合区域地质构造特征,可以认为,早期花岗岩的形成与俯冲板块的断离并折返有关,而晚期花岗岩的形成与造山带岩石圈地幔拆沉作用有关.吴才来 郜源红 李兆丽 雷敏 秦海鹏 李名则 刘春花 Ronald B FROST Paul T ROBINSON Joseph L WOODEN 2014中国科学:地球科学2014,44,10:27
11Dur’ngoi Ophiolite in East Kunlun, Northeast Tibetan Plateau: Evidence for Paleo-Tethyan Suture in Northwest China显示文摘The A’nyemaqen (阿尼玛卿) ophiolite belt along the southern margin of the East Kunlun (昆仑) Mountains marks the suture formed by the closure of paleo-Tethys. The Dur’ngoi ophiolite in the eastern part of this belt consists of meta-peridotite, mafic-ultramafic cumulates, sheeted dikes and basaltic lavas. The meta-peridotites consist of dunite, harzburgite, lherzolite, feldspar-bearing lherzolite and garnet-bearing lherzolite and contain residual spinel with Cr# [100×Cr/(Cr+Al)] ranging from 30 to 57 and Mg# [100×Mg/(Mg+Fe2+)] ranging from 50 to 75, indicating an Aland Mg-rich series. The meta-peridotites have a relatively narrow range of composition with Mg# of 89.2–92.6, Al2O3 contents of (1–4) wt.% and slightly depleted chondrite normalized REE patterns, indicating that they represent relict mantle material that has undergone intermediate to low degrees of partial melting. Garnets in the lherzolite are andradite, enriched in Ca and Fe and depleted in Mg and Al (And=95–97, Pyr=0.3–5, Gro=0–3), indicating a metamorphic origin. The cumulate rocks mainly consist of dunite, wehrlite, pyroxenite and gabbro. A well-layered gabbro-pyroxenite complex is defined by modal variations in plagioclase and pyroxene. Blocks of garnet-pyroxenite or rodingite are locally present in the meta-peridotites. Garnets in the cumulate rocks are grossular (Gro=69–90, And=9–19, Br=1–12), also metamorphic origin. The diabase dikes are moderately depleted in LREE [(La/Sm)N=0.5–0.8] and HREE resulting in slightly convex chondrite-normalized patterns with slightly positive Eu anomalies (δEu=1.1–1.3). The basaltic lavas have REE patterns similar to those of MORB with (La/Sm)N ratios of 0.5–1 and small negative Eu anomalies. They appear to have been derived from a depleted mantle source and to have undergone little or no differentiation during crystallization. SHRIMP U-Pb dating of zircons from the basalts yields 206Pb/238U ages of 276–319 Ma (average 308.0±4.9 Ma). The Dur’ngoi ophiolite is interpreted as a dismembered fragment of paleo-oceanic crust emplaced during closure of the paleo-Tethyan Ocean basin. Three other suites of oceanic lavas are recognized in the area: island arc volcanic (IAV) rocks, possible back arc basin (BAB) basalts and possible post-collisional volcanic (PCV) and plutonic rocks. The distribution of these rocks suggests north-directed subduction. Opening of the A’nyemaqen oceanic basin started at least as early as Late Carboniferous (308 Ma) and the basin probably closed during the Early Triassic. The IAV formed in Late Permian (260 Ma), the BAB in Early–Middle Triassic, and the PCV in Late Triassic. Several large scale, ductile, sinistral strike-slip fault zones, extending hundreds to thousands kilometers, formed along or north of the suture during the Early–Late Triassic, e.g., they are the south margin fault zone of East Kunlun (200–220 Ma), the Altyn Tagh fault (220–230 Ma), and the North Qaidam fault zone (240–250 Ma). These strike-slip faults were probably generated by oblique subduction and closure of the paleo-Tethyan Ocean basin, possibly during exhumation of the subducted plate or uplift of the overriding plate, coincident with post-collisional magmatism.杨经绥 史仁灯 吴才来 王希斌 Paul T Robinson 2009Journal of China University of Geosciences2009,20,2:26
12非财务指标与企业财务业绩相关吗——一项基于中国国有企业的实证研究显示文摘非财务指标是否能预测企业财务业绩的增长,综合业绩指标体系是否适合我国企业,是我国理论与实务界普遍关心的问题。本文以76家国有企业为样本,系统分析了非财务指标“客户满意度”与企业财务业绩的相关关系,为我国企业建立综合业绩评价体系找到了实证依据。研究表明,客户满意度高的企业具有更高的盈利能力;从客户满意度提高带来的两方面作用来看,企业更可能是通过提高单位产品的利润率来提高盈利能力,而不是通过增加销售来提高盈利能力。张川 潘飞 John Robinson 2006中国工业经济2006,,11:24
13Zircon SHRIMP U-Pb dating of granites from Dulan and the chronological framework of the North Qaidam UHP belt, NW China显示文摘Zircon SHRIMP dating of granites from Dulan,east segment of North Qaidam UHP belt shows that they are 406.6±3.5 Ma for Yematan-E,407.3±4.3 and 397±6 Ma for Balijiehatan-W,404.5±4.0 and 397.0±3.7 Ma for Shuiwenzhan-N,380.5±5.0 Ma for Shuiwenzhan-S,382.5±3.6 and 372.5±2.8 Ma for Chachagongma.These granites from Dulan represent the products of the third and fourth periods of Paleozoic magmatism in North Qaidam.Geochemically,the granitoids with metalumious to weak peratuminous are quartz diorite,granodiorite,and granite in composition and mainly belong to calc-alkaline series,a few samples to calc or alkali-calc series.The third period of granites is a rock association of granodiorite+granite,with initial 87Sr/86Sr ratios from 0.7082 to 0.7110 and T2DM model ages from 1.41–1.90 Ga;and the fourth period of granites is a rock association of quartz diorite+granodiorite+granite,with initial 87Sr/86Sr ratios from 0.7072 to 0.7091 and T2DM model ages from 1.07–1.38 Ga.Therefore,the third period of granites has higher initial 87Sr/86Sr ratios and T2DM model ages.On the contrary,the fourth period of granites has Nd(t)values from 0.6 to-3.0,higher than that of the third granite with Nd(t)values-3.2 to-9.3.Thus,the data comparison indicates that the third granites may derive from Paleo-proterzoic continental crust with mantle material whereas the fourth granites may derive from the Meso-proterzoic basalt crust with continental material.Combined with regional geology,we thought that the third granites were formed relative to plate exhumation and the fourth granites to delamination of the lithospheric mantle.WU CaiLai GAO YuanHong LI ZhaoLi LEI Min QIN HaiPeng LI MinZe LIU ChunHua Ronald B FROST Paul T ROBINSON Joseph L WOODEN 2014Science China Earth Sciences2014,57,12:21
141997年新疆伽师强震群发展过程中发震断层间相互作用的影响显示文摘1997年发生在新疆伽师的强震群迄今仍在持续活动,从1997年1月21日震群发生至1997年10月18日,共发生5级以上地震15次.震群发生前,该地区几乎没有地震活动.根据伽师震群地震的精确定位结果及震源机制解,我们设定该震群的发震构造是一组NNW(北北西)向的雁形右旋走滑断层和一组NE(北东)向雁形正倾滑断层.并以此作为模拟该区域理论地震活动的力学模型,开展震群区域理论地震活动的模拟研究.模拟结果证实了断层间的相互作用或应力传递能产生震群活动的猜测,并对伽师震群中为何部分地震的震源机制是正断层进行了合理解释.进一步推测伽师位于地壳厚度的陡变带也可能是引起该地区地震活动丛集发生的原因.周仕勇 姜明明 Russell Robinson 2006地球物理学报2006,49,4:21
15Diamonds and Other Exotic Minerals Recovered from Peridotites of the Dangqiong Ophiolite, Western Yarlung-Zangbo Suture Zone, Tibet显示文摘Various combinations of diamond, moissanite, zircon, quartz, corundum, rutile, titanite, almandine garnet, kyanite, and andalusite have been recovered from the Dangqiong peridotites. More than 80 grains of diamond have been recovered, most of which are pale yellow to reddish-orange to colorless. The grains are all 100-200 μm in size and mostly anhedral, but with a range of morphologies including elongated, octahedral and subhedral varieties. Their identification was confirmed by a characteristic shift in the Raman spectra between 1325 cm^(-1) and 1333 cm^(-1), mostly at 1331.51 cm^(-1) or 1326.96 cm^(-1). Integration of the mineralogical, petrological and geochemical data for the Dongqiong peridotites suggests a multi-stage formation for this body and similar ophiolites in the Yarlung-Zangbo suture zone. Chromian spinel grains and perhaps small bodies of chromitite crystallized at various depths in the upper mantle, and encapsulated the UHP, highly reduced and crustal minerals. Some oceanic crustal slabs containing the chromian spinel and their inclusion were later trapped in suprasubduction zones(SSZ), where they were modified by island arc tholeiitic and boninitic magmas, thus changing the chromian spinel compositions and depositing chromitite ores in melt channels.XIONG Fahui YANG Jingsui ROBINSON Paul T.

20Distinctive melt activity and chromite mineralization in Luobusa and Purang ophiolites, southern Tibet: constraints from trace element compositions of chromite and olivine显示文摘To investigate the factors controlling the mineralization in ophiolites we systematically compared the petrology and mineral compositions of the harzburgites/lherzolites, dunites and chromitites in the Luobusa and Purang ophiolites. Generally, the petrological features and trace element compositions of chromite and olivine in peridotite and chromitite are distinctly different between the two ophiolites.In Luobusa, boninitic melts are inferred to have interacted with the harzburgites and modified the distributions of some trace elements(e.g., Ni, Mn and V) in chromite and olivine. The subsequently formed dunites and chromitites experienced significant elemental exchange. In contrast, the Purang ophiolite contains a wider range of chromitite compositions and records diverse melt activities, such as the growth of relatively abundant secondary clinopyroxene. The metasomatic melts were enriched in Al and depleted in Si, Na and highly incompatible trace elements(e.g., Nb, Zr). Such melts resemble MORBlike melts proposed in the literature but are assumed to be more hydrous than typical MORB because of presence of hydrous minerals. The parental magmas of the Purang dunites and intermediate chromitites are inferred to be compositionally intermediate between boninitic and MORB-like melts. In addition,the more refractory nature of the Luobusa harzburgites facilitated a high Cr concentration gradient with the interacting melts, making it easier to increase Cr in the melts. Crystallization of clinopyroxene and amphibole in the Purang ophiolite accommodated significant amounts of Cr and water, respectively,and negatively affected Cr concentration and chromite crystallization. The concentration of chromite to form chromitites requires the presence of focused melt channels.Benxun Su Meifu Zhou Jiejun Jing Paul T.
