| 1 | Linker extension through hard-soft selective metal coordination for the construction of a non-rigid metal-organic framework显示文摘A metal-organic framework (MOF) has been obtained by using a linker extension strategy. Three di-anions of 4-(3,5-dimethyl- 1H-pyrazol-4-yl)-benzoic acid coordinate to three Cu(Ⅰ) ions forming an extended trigonal planar ligand, which links three di-copper paddlewheel units giving rise to a Pt3O4 net. | WEI ZhangWen YUAN DaQiang ZHAO XiaoLiang SUN DaoFeng ZHOU Hong-Cai | 2013 | Science China Chemistry2013，56，4： | 5 |

| 3 | Carbamylated erythropoietin regulates immune responses and promotes long-term kidney allograft survival through activation of PI3K/AKT signaling显示文摘Modulation of alloimmune responses is critical to improving transplant outcome and promoting long-term graft survival.To determine mechanisms by which a nonhematopoietic erythropoietin(EPO)derivative,carbamylated EPO(CEPO),regulates innate and adaptive immune cells and affects renal allograft survival,we utilized a rat model of fully MHC-mismatched kidney transplantation.CEPO administration markedly extended the survival time of kidney allografts compared with the transplant alone control group.This therapeutic effect was inhibited when the recipients were given LY294002,a selective inhibitor of the phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)signaling pathway or anti-EPO receptor(EPOR)antibody,in addition to CEPO.In vitro,CEPO inhibited the differentiation and function of dendritic cells and modulated their production of proinflammatory and anti-inflammatory cytokines,along with activating the PI3K/AKT signaling pathway and increasing EPOR mRNA and protein expression by these innate immune cells.Moreover,after CD4^(+)T cells were exposed to CEPO the Th1/Th2 ratio decreased and the regulatory T cell(Treg)/Th17 ratio increased.These effects were abolished by LY294002 or anti-EPOR antibody,suggesting that CEPO regulates immune responses and promotes kidney allograft survival by activating the PI3K/AKT signaling pathway in an EPOR-dependent manner.The immunomodulatory and specific signaling pathway effects of CEPO identified in this study suggest a potential therapeutic approach to promoting kidney transplant survival. | Ning Na Daqiang Zhao Jinhua Zhang Jiaqing Wu Bin Miao Heng Li Yingxun Luo Zuofu Tang Wensheng Zhang Joseph A.Bellanti Song Guo Zheng | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 4 |
| 4 | A new hybrid method—combined heat flux method with Monte-Carlo method to analyze thermal radiation显示文摘A new hybrid method, Monte-Carlo-Heat-Flux (MCHF) method, was presented to analyze the radiative heat transfer of participating medium in a three-dimensional rectangular enclosure using combined the Monte-Carlo method with the heat flux method. Its accuracy and reliability was proved by comparing the computational results with exact results from classical 'Zone Method'. | Zengwu Zhao Daqiang Cang Wenfei Wu Yike Li Baowei Li | 2006 | Journal of University of Science and Technology Beijing2006，13，1： | 2 |

| 6 | Microbial diversity in lake sediments detected by PCR-DGGE显示文摘In this study,PCR-denaturing gradient gel electrophoresis(DGGE)was applied to analyze the microbial communities in lake sediments from Lake Xuanwu,Lake Mochou in Nanjing and Lake Taihu in Wuxi.Sediment samples from seven locations in three lakes were collected and their genomic DNAs were extracted.The DNA yields of the sediments of Lake Xuanwu and Lake Mochou were high(10 mg/g),while that of sediments in Lake Taihu was relatively low.After DNA purification,the 16S rDNA genes(V3 to V5 region)were amplified and the amplified DNA fragments were separated by parallel DGGE.The DGGE profiles showed that there were five common bands in all the lake sediment samples indicating that there were similarities among the populations of microorganisms in all the lake sediments.The DGGE profiles of Lake Xuanwu and Lake Mochou were similar and about 20 types of micro-organisms were identified in the sediment samples of both lakes.These results suggest that the sediment samples of these two city lakes(Xuanwu,Mochou)have similar microbial communities.However,the DGGE profiles of sediment samples in Lake Taihu were significantly different from these two lakes.Furthermore,the DGGE profiles of sediment samples in different locations in Lake Taihu were also different,suggesting that the microbial communities in Lake Taihu are more diversified than those in Lake Xuanwu and Lake Mochou.The differences in microbial diversity may be caused by the different environmental conditions,such as redox potential,pH,and the concentrations of organic matters.Seven major bands of 16S rDNA genes fragments from the DGGE profiles of sediment samples were further reamplified and sequenced.The results of sequencing analysis indicate that five sequences shared 99%-100%homology with known sequences(Bacillus and Brevibacillus,uncultured bacteria),while the other two sequences shared 93%-96%homology with known sequences(Acinetobacter,and Bacillus).The study shows that the PCR-DGGE technique combined with sequence analysis is a feasible and efficient method for the determination of microbial communities in sediment samples. | Xinqing ZHAO Liuyan YANG Can CHEN Lin XIAO Lijuan JIANG Zhe MA Haowei ZHU Zhenyang YU Daqiang YIN | 2008 | Frontiers in Biology2008，3，3： | 0 |
