1Arsenic trioxide and microRNA-204 display contrary effects on regulating adipogenic and osteogenic differentiation of mesenchymal stem cells in aplastic anemia显示文摘我们的以前的研究证明了砷三氧化物(ATO ) 在与无形的贫血症(AA ) 对待病人有临床的功效。然而,机制尚待被阐明。骨头髓的重要部件造血的微型环境,骨头髓间充质的干细胞(BMSC ) ,经常在 AA 病人被改变。在这研究, AA BMSC 是容易的被导致进 adipocytes 而非造骨细胞,这被发现。ATO 治疗能部分至少恢复 AA BMSC 的区别不平衡。我们进一步在 AA BMSC 区别作为一个关键管理者识别了 miR-204。酶记者试金证明 miR-204 能直接绑在 Runx2 mRNA 的 3-untranslated 区域,调整成骨的一个关键抄写因素。而且, adipogenic 区别被支持, osteogenic 区别在 miR-204 被禁止过去表示的房间而成骨被提高, adipocyte 形成在房间被禁止,那失去了 miR-204 功能,它建议了它的内长的功能。一起我们证明 ATO 能禁止 adipogenic 区别,但是在 AA BMSC 支持 osteogenic 区别,在 AA 病人为 ATO 临床的功效提供可能的解释。MiR-204 戏在调整 BMSC 区别的一个关键角色,和下面调整的 miR-204 表示可能是新奇策略对待 AA。Junmei Zhao Chao Wang Yongping Song Baijun Fang 2014Acta Biochimica et Biophysica Sinica2014,46,10:7
2An efficient algorithm for finding the largest chain graph according to a given chain graph显示文摘Chain graph (CG) is a general model of graphical Markov models. Some different chain graphs may describe the same conditional independence structure, then we say that these CGs are Markov equivalent. In 1990 Frydenberg showed that every class of Markov equivalent CGs has a CG which is called the largest chain graph with the greatest number of lines. This paper presents an efficient algorithm for finding the largest chain graph of the corresponding Markov equivalent class of a given CG. The computational complexity of the algorithm is O(n3). It is more efficient than the complexity O(n!) of the present algorithms. Also a more intuitive graphical characterization of the largest chain graph is provided based on the algorithm in this paper.LIU Baijun,ZHENG Zhongguo & ZHAO Hui School of Mathematical Sciences, Peking University, Beijing 100871, China Department of Statistics, Central China Normal University, Wuhan 430079, China 2005Science China Mathematics2005,48,11:2

12Carboxyl-functionalized Nanocellulose Reinforced Nanocomposite Proton Exchange Membrane显示文摘Nanocellulose(NCC) was prepared through the acid hydrolysis of microcellulose(MCC) and was reacted with maleic anliydride to obtain carboxyl-functionized nanocellulose(MA-NCCs). The presence of .OH and .SO3H on the surface of rod-like MA-NCC was confirmed by Fourier transfonn infrared spectrometry(FTIR). Sulfonated poly(aryl ether ether ketone ketone)(Ph-SPEEKK) was synthesized with bis(4-fluorophenyl-methanone) and 2-phenylhydroquinone as monomer. MA-NCC/Ph-SPEEKK nanocomposite membranes with different MA-NCCs content were prepared, and their properties were characterized. Compared with Ph-SPEEKK, MA-NCC/Ph-SPEEKK nanocomposite membrane showed better mechanical and thermal properties and higher proton conductivity. The proton conductivity of the composite membrane with 4%(mass fraction) MA-NCCs under 80℃ was 0.095 S/cm. And its tensile strength reached 30.3 MPa, which was 21.2% higher than that of Ph-SPEEKK pure polymer membrane.YANG Xue WEI Yingcong CHU Xuefeng ZHAO Qi YAN Wenling DONG Chenjun LIU Baijun SUN Zhaoyan HU Wei ZHANG Niaona 2019Chemical Research in Chinese Universities2019,35,4:0

14Proton Conductivity Improvement Effect of Cellulose on SPEEKK Based PEM显示文摘The proton exchange membranes(PEMs) were prepared through the solution mixing method of sulfonated poly(etlier ether ketone ketoneXsPEEKK) and cellulose. Cellulose was dissolved by 1-ally 1-3-methylimidazolium chioride(AMIMC1) and then mixed with sPEEKK solution. sPEEKK/cellulose(SC) composite membranes were prepared by solution casting. The membranes have high flexibility and transparency, which meant the compounding in molecular level. Meanwhile, the composite membranes showed excellent mechanical properties and high proton conductivity. The mechanical property reached 29 MPa, and the proton conductivity was as high as 0.32 S/cm. Thus, as a kind of biomaterials, cellulose could be ail excellent reinforcing material for poly(aryl ether ketone)(PAEK) based PEMs.ZHAO Qi LIANG Xiaoxiao YOU Yingxue WANG Yuliang DU Xinwei LIU Baijun HU Wei 2019Chemical Research in Chinese Universities2019,35,5:0
15Pluripotent stem cells exhibiting similar characteristics can be isolated from human fetal bone marrow, heart, liver, muscle, lung, derma, kidney, and fat显示文摘Previously,we reported that a cell population derived from human fetal bone marrow(BM),termed here Flk1+CD34−postembryonic pluripotent stem cells(PPSCs)that have the characteristics of mesenchymal stem cells(MSCs),could differentiate into ectodermal,endodermal and mesodermal cell types at the single cell level in vitro,and that these cells could also differentiate into the epithelium of liver,lung,gut,as well as the hematopoietic and endothelial lineages after transplantion into irradiated non-obese diabetic/severe combined immunodeficient(NOD/SCID)mice.In this study,we further isolated pluripotent stem cells from human fetal heart,liver,muscle,lung,derma,kidney,and fat and then analyzed the characteristics and function of these stem cells.It was found that the phenotype of the culture-expanded pluripotent stem cells from different fetal tissues was similar to BM-derived Flk1^(+)CD34^(−)PPSCs,i.e.Flk1 and CD44 positive,GlyA,CD34,CD45,class I-HLA and HLA-DR negative.Morphologically,these cells were fibroblast-like and the doubling time was about 30 h.More importantly,culture-expanded pluripotent stem cells from all these fetal tissues were able to differentiate into cells with morphologic and phenotypic characteristics of adipocytes,osteocytes,neurons,glial cells and hepatocytes.These pluripotent stem cells with characteristics similar to fetal BM-derived Flk1^(+)CD34^(−)PPSCs can be selected and cultured from tissues other than the BM.This phenomenon may help explain the“stem cell plasticity”found in multiple human tissues.In addition,as fetal BM-derived Flk1^(+)CD34^(−)PPSCs,these pluripotent stem cells from different fetal tissues had the capacity for self-renewal and multi-lineage differentiation even after being expanded for more than 40 population doublings in vitro.Thus,they may be an ideal source of stem cells for treatment of inherited or degenerative diseases.FANG Baijun SONG Yongping ZHAO Chunhua SHI Mingxia LIN Quande 2007Frontiers of Medicine2007,1,2:0
