background: Hepatitis b virus(HbV) replication has been reported to be involved in many extrahepatic viral disorders; however, the mechanism by which HbV is trans-infected into extrahepatic tissues such as HbV associated myocarditis remains largely ***:In this study, we showed that human cord blood endothelial progenitor cells (EPCs), but not human umbilical vein endothelial cells (HUVECs) could be effectively infected by uptake of HbV in *** of EPCs with HbV resulted in HbV DNA and viral particles were detected in EPCs at day 3 after HbV challenge, which were peaked around day 7 and declined in 3 ***, HbV envelope surface and core antigens were first detected in EPCs at day 3 after virus challenge and were retained to be detectable for 3 weeks.

Investigation of Fuel Retention via Gas Balance on HT-7

Line-of-shower trigger method to lower energy threshold for GRb detection using LHAASO-WCDA

第18届国际真空大会

作者： b. cao, j.G. Li, j.S. Hu, q. Chen, G.H. Wu, j.H. Li, Y. Chen, Y.W. Yu Institute of Plasma Physics, Chinese Academy of Sciences, Hefei 230031, PR China

In the next fusion device, fuel retention will be a major issue, particularly for the long pulse discharges foreseen in ITER (400smin). In ITER, the tritium retention in the vessel is 350g [1] for plasma limit due to tritium recycling problem and 2000g for safe limit. The database of fuel retention in long pulse tokamaks is very important to predict the retention in ITER.

Space plasmas often possess non-Maxwellian distribution functions which have a significant effect on the plasma waves. When a laser or electron beam passes through a dense plasma, hot low density electron populations can be generated to alter the wave damping/growth rate. In this paper, we present theoretical analysis of the nonlinear Landau damping for Langmuir waves in a plasma where two electron populations are found. The results show a marked difference between the Maxwellian and non-Maxwellian instantaneous damping rates when we employ a non-Maxwellian distribution function called the generalized （r, q） distribution function, which is the generalized form of the kappa and Maxwellian distribution functions. In the limiting case of r = 0 and q→∞, it reduces to the classical Maxwellian distribution function, and when r = 0 and q→k ＋1, it reduces to the kappa distribution function.

目的:比较脐血间充质干细胞和骨髓间充质干细胞对植物血凝素诱导的淋巴细胞增殖的抑制作用。方法:实验于2005-07/2006-03在南昌大学第二附属医院血液病研究所及江西省医学分子重点实验室完成。①实验材料:脐带血9份,由南昌大学第二附属医院妇产科提供,产妇及其家属均知情同意。正常骨髓9份,由南昌大学第二附属医院血液科门诊及住院患者提供,均附有捐赠同意书。外周血9份,取自正常自愿者。本实验经医学伦理委员会批准。②实验方法:无菌条件下采集脐血、骨髓和正常人外周血,分离单个核细胞。脐血及骨髓单个核细胞以1×109 L-1接种于培养瓶中,加入含体积分数为0.1的小牛血清、1×10-3mol/L氢化可的松的IMDM培养液,7d后换液,去除悬浮细胞,以后每3～4d换液1次,待细胞90%融合后,胰蛋白酶+乙二胺四乙酸混合消化,传代培养,取第3代细胞用于实验。正常人外周血单个核细胞以1×109 L-1接种于培养瓶中,加入含体积分数为0.1的小牛血清、10mg/L植物血凝素的IMDM液,培养3d后收集细胞用于实验。③实验评估:采用流式细胞术检测脐血间充质干细胞及淋巴细胞表面分子。取第3代的脐血和骨髓间充质干细胞,体外诱导培养后以脂肪染色液鉴定其向脂肪细胞的分化情况。将不同细胞浓度的脐血和骨髓间充质干细胞分别加入到植物血凝素诱导的外周血淋巴细胞增殖体系中,比较两种不同来源的间充质干细胞对淋巴细胞增殖的调控作用。结果:①脐血间充质干细胞和骨髓间充质干细胞的培养及鉴定:第3代脐血间充质干细胞表面分子标记率CD29为85.18%,CD166为72.52%,CD54为33.70%,CD45为6.70%,CD13为1.51%,CD34为0.23%。正常人外周血单个核细胞中的CD3+T细胞为60%～70%,CD20+b细胞为3.5%～4.5%。脐血间充质干细胞诱导培养3周,可见呈桔黄色的脂肪细胞。②脐血间充质干细胞及骨髓间充质干细胞对淋巴细胞增殖的抑制:淋巴细胞:间充质干细胞为1∶1,1∶0.5,1∶0.1,1∶0.05,1∶0.02,1∶0.01时,脐血间充质干细胞对淋巴细胞增殖的抑制率分别为(49.5±4.8)%,(58.4±6.0)%,(38.1±4.0)%,(31.4±3.2)%,(24.3±3.2)%,(12.6±6.7)%,而骨髓间充质干细胞对淋巴细胞增殖的抑制率分别为(52.4±8.4)%,(65.1±9.7)%,(34.7±4.5)%,(13.0±6.4)%,(-10.7±12.6)%,(-43.9±9.4)%。后3种细胞浓度比例脐血间充质干细胞对淋巴细胞的抑制作用明显强于骨髓间充质干细胞(t=7.72,8.14,14.68,P均<0.05)。结论:脐血间充质干细胞与骨髓间充质干细胞一样,也具有抑制植物血凝素诱导淋巴细胞增殖的作用,抑制效果与间充质干细胞数量有关。低浓度的脐血间充质干细胞对淋巴细胞的抑制作用明显强于骨髓间充质干细胞。
