1激光剥蚀信号在线平滑和去汞装置:原位微区铅同位素准确分析利器显示文摘激光原位微区分析可在微观尺度上完成样品的元素定量分析或同位素组成测定,为研究成岩、成矿物质来源和追踪地壳与地幔演化历史提供了独特的观察视野。但是,激光剥蚀等离子体质谱的一些缺陷阻碍了地质样品的高精度、高空间分辨率分析,比如:剥蚀池的位置效应、低剥蚀速率下信号波动影响、激光剥蚀脉动式信号导致的光谱螺纹效应、高频激光剥蚀造成的元素分馏效应等。为此,一些学者设计了不同规格和样式的激光剥蚀信号平滑装置来克服这些问题。但是,这些信号平滑装置普遍还存在气体吹扫时间过长和降低激光剥蚀信号灵敏度等问题。因此,研制新型的信号平滑装置对改善LA—ICP—MS的数据质量具有重要的意义。Hu Z Zhang W Liu Y Gao S Li M Zong K Chen H Hu S 刘勇胜 2015矿物岩石地球化学通报2015,34,4:114
22019新型冠状病毒基因组特征和流行病学:病毒起源和受体结合的意义显示文摘研究者对来自9例新型冠状病毒肺炎住院患者的支气管肺泡灌洗液样本和培养的分离株进行了下一代测序。从这些个体中获得了严重急性呼吸综合征-冠状病毒2(severe acute respiratory syndrome-coronavirus 2,SARS-CoV-2)的完整和部分基因组序列。利用Sanger测序连接病毒重叠群以获得全长基因组,cDNA末端快速扩增确定终端区。对这些SARSCoV-2基因组和其他冠状病毒基因组进行了系统进化分析,以确定该病毒的进化史并有助于推断其可能的起源。刘青(译) 刘莉(审校) Lu R Zhao X Li J Niu P Yang B Wu H Wang W Song H Huang B Zhu N Bi Y Ma X Zhan F Wang L Hu T Zhou H Hu Z Zhou W Zhao L Chen J Meng Y Wang J Lin Y Yuan J Xie Z Ma J Liu WJ Wang D Xu W Holmes EC Gao GF Wu G Chen W Shi W Tan W 2020中华高血压杂志2020,28,3:516

4^11C-PIBPET和^18F-FDGPET显像诊断阿尔茨海默病与遗忘型轻度认知损害的临床价值显示文摘目的应用11C-PIB PET和18F-FDG PET显像研究阿尔茨海默病和遗忘型轻度认知损害患者β-淀粉样蛋白(Aβ)沉积与葡萄糖代谢之间的关系,联合载脂蛋白E(ApoE)基因型进一步探讨遗忘型轻度认知损害与阿尔茨海默病的相关性。方法利用PET显像对阿尔茨海默病(14例)、遗忘型轻度认知损害(10例)和正常对照者(5例)脑组织Aβ沉积和葡萄糖代谢变化进行分析,采用聚合酶链反应-限制性片段长度多态性方法对ApoE基因型进行分析。结果阿尔茨海默病组患者11C-PIB标准化摄取比值在下顶叶、颞叶外侧、额叶、后扣带回皮质和楔前叶、枕叶和纹状体均高于正常对照组(P<0.05);遗忘型轻度认知损害组患者脑组织11C-PIB结合水平呈双峰形。11C-PIB+aMCI亚组与阿尔茨海默病组、11C-PIB-aMCI亚组与正常对照组之间11C-PIB标准化摄取比值差异均无统计学意义(P>0.05)。18F-FDG PET显像显示,3/5例11C-PIB+aMCI亚组患者双侧顶叶、颞叶和楔前叶代谢减低,其中2例ApoEε4等位基因携带者随访期间进展至阿尔茨海默病;3/5例11C-PIB-aMCI亚组患者双侧额叶和前扣带回代谢减低。结论11C-PIB PET显像是筛查具有阿尔茨海默病病理特点的遗忘型轻度认知损害患者的有效工具。具有阿尔茨海默病病理特征的遗忘型轻度认知损害患者可伴有顶叶、颞叶外侧皮质和楔前叶代谢减低,其中ApoEε4等位基因携带者更易进展至阿尔茨海默病痴呆。Shi Zhihong Wang Ying Liu Shuai Liu Shuling Z hou Yuying Wang Jinhuan Cai Li Gao Shuo Ji Yong 2014中国现代神经疾病杂志2014,14,3:8

6Magnetic resonance evaluation of transplanted mesenchymal stem cells after myocardial infarction in swine显示文摘Objectives To trace and evaluate intracoronary transplanted mesenchymal stem cells(MSCs) labeled with superparamagnetic iron oxide(SPIO) by using magnetic resonance imaging(MRI) in a swine model of myocardial infarction (MI).Methods MSCs were transfected with a lentiviral vector carrying the gene encoding green fluorescent protein (GFP) and labeled in vitro with SPIO.Two weeks after MI, swine were randomized to intracoronary transplantation of dual -labeled MSCs(n = 10),MSCs-GFP(n = 10) and saline(n = 5).MRI examination was performed with a 1.5T clinical scanner at 24 hours,3 weeks and 8 weeks after cells transplantation. Signal intensity(SI) changes,cardiac function and MI size were measured using MRI.Correlation between MR findings and histomorphologic findings was also investigated. Results The labeling efficiency at a combination of 25μg Fe/ml SPIO and 0.8 pi/ml Lipofectamine 2000 reached 100%.SPIO labeling did not affect GFP fluorescence and dual-labeling did not affect cell proliferation(P>0.05). Multipotentiality was not affected especially for cardiomyocyte-like cells differentiation.Cardiac cell marker of a-MHC and actinin were positively expressed by immunofluorescence staining after induction.SI on T2 * WI decreased substantial- ly in the interventricular septum 24 hours after injection of MSCs.The intensity of hypo-intense signals appeared to increase throughout the later time points.Changes in SI at 24 hours,3 weeks and 8 weeks were 52.98%±10.74%,21.53%±5.40%and 6.23%±2.01%,respectively(P<0.01).DE-MRI demonstrated both dual-labeled MSCSs and MSCs-GFP could dramatically reduce the size of MI and improve cardiac function. Histological data revealed that prussian blue stain-positive cells were found mainly in the border zone which also showed green fluorescence but negative for macrophage marker(CD68).Gross pathologic examination revealed that engrafted MSCs dramatically reduce the extent of necrotic myocardium and promote the regeneration of new,contractile myocardium along the subendocardial surface of the MI. Conclusions MSCs could be efficiently and safely labeled with SPIO and GFP,and could be detected reproducibly and noninvasively in vivo using cardiac MRI.Intracoronary transplantation of dual-labeled MSCs could increase cardiac function and reduce the size of MI.KE Yang~1,PENG Chao-quan~1,XIANG Peng~1,ZHANG Cheng-xi~1, ZOU Li-yuan~1,WU Xiao~1,YA Gao~1,KANG Z huang~2,HE Ke-ke~2,LIU Jin-lai~1 (1.Department of Cardiology,The Third Affiliated Hospital, Sun Yat-sen University,Guangzhou 2.Department of Radiology, the Third Affiliated Hospital,Sun Yat-sen University, Guangzhou 5100630 3.Center for Stem Cell Biology and Tissue Engineering,Sun Yat-sen University,Guangzhou 5100120) 2011岭南心血管病杂志2011,17,S1:7

15Laser patterning for the study of MSC cardiogenic differentiation at the single-cell level显示文摘Mesenchymal stem cells(MSCs)have been cited as contributors to heart repair through cardiogenic differentiation and multiple cellular interactions,including the paracrine effect,cell fusion,and mechanical and electrical couplings.Due to heart–muscle complexity,progress in the development of knowledge concerning the role of MSCs in cardiac repair is heavily based on MSC–cardiomyocyte coculture.In conventional coculture systems,however,the in vivo cardiac muscle structure,in which rod-shaped cells are connected end-to-end,is not sustained;instead,irregularly shaped cells spread randomly,resulting in randomly distributed cell junctions.Consequently,contact-mediated cell–cell interactions(e.g.,the electrical triggering signal and the mechanical contraction wave that propagate through MSC–cardiomyocyte junctions)occur randomly.Thus,the data generated on the beneficial effects of MSCs may be irrelevant to in vivo biological processes.In this study,we explored whether cardiomyocyte alignment,the most important phenotype,is relevant to stem cell cardiogenic differentiation.Here,we report(i)the construction of a laser-patterned,biochip-based,stem cell–cardiomyocyte coculture model with controlled cell alignment;and(ii)single-cell-level data on stem cell cardiogenic differentiation under in vivo-like cardiomyocyte alignment conditions.Zhen Ma Qiuying Liu Huaxiao Yang Raymond B Runyan Carol A Eisenberg Meifeng Xu Thomas K Borg Roger Markwald Yifei Wang Bruce Z Gao 2013Light(Science & Applications)2013,2,1:2
