| 1 | One pot synthesis, crystal structures and properties of two new MOFs with imidazole-containing tripodal ligand显示文摘Two new different Cu(Ⅱ) MOFs with the same 1,3,5-tris(1-imidazolyl) benzene(tib) ligand {[Cu(tib)2]·(H2O)2·Br2}n(1) and {[Cu2(tib)·Br·Cl]·2Br}n(2) were obtained by one pot synthesized of tib with CuBr in the presences of HCl and water. X-ray single crystal diffraction analyses indicate that both complexes 1 and 2 have two dimensional frameworks containing different building blocks. Each Cu(Ⅱ) atom in complex 1 is coordinated by four N atoms from different tib ligands. However, there are two different cryptographic Cu(Ⅱ) atoms in complex 2, one is four coordinated by two bromine atoms and two N atoms from different tib ligands, the other is six coordinated by two chloride atoms and four N atoms from different tib ligands. The thermal gravimetric analysis of complexes 1 and 2 are depicted in the paper. | TANG YunZhi YU YinMei XIONG JianBo YAO Qiong TAN YuHui GAO JiXing WEN HeRui | 2014 | Science China Chemistry2014，57，11： | 2 |

| 3 | Constructing a lithiophilic polyaniline coating via in situ polymerization for dendrite-free lithium metal anode显示文摘Metallic lithium is regarded as one of the most promising electrode materials to break through the energy density bottleneck of current commercial lithium-ion batteries.However,the practical implementation of lithium metal anode is limited by the unstable electrode interface significantly,which directly induces a low Coulombic efficiency,short cycling lifespan,and dendritic lithium growth behavior.In this study,via in situ electropolymerization,lithiophilic and conformal polyaniline layer is developed to improve the initial lithium nucleation and plating process,reducing the interface charge transfer resistance and promoting uniform lithium plating/stripping behavior.Meanwhile,the polyaniline layer exhibits good adhesion to the substrate.As a result,the Li/Cu half cell delivers a high Coulombic efficiency of 99.1%for 400 cycles at 1.0 mA·cm^(−2)with polyaniline layer.In addition,long-term stable cycling at a current density of 1.0 mA·cm^(−2)for 1300 h has been achieved for lithium metal anode.This strategy provides a new perspective for the practical lithium metal batteries. | Xiaosong Xiong Qiao Qiao Qi Zhou Xinbing Cheng Lili Liu Lijun Fu Yuhui Chen Bin Wang Xiongwei Wu Yuping Wu | 2023 | Nano Research2023，16，6： | 0 |
| 4 | Algebraic test of relative form closure grasps with its implementation显示文摘This paper presents an approach to algebraic detection of relative form closure for a multi-fingered grasp G and gives an attention to the classification of relative form closures.Whether or not a grasp G is of relative form closure has been verified by the geometric criterion 0?rintC[G](Xiong Y L,Xiong X R.Algebraic structure and geometric interpretation of rigid complex fixture system.IEEE Trans Autom Sci Eng,2007,4:252–264;Xiong Y L.Theory of point contact restraint and qualitative analysis of robot grasping.Sci China Ser A-Math,1994,37:629–640).Our aim is at transferring the geometric criterion into an algebraic formulation by a theorem that a grasp G is relative form closure,if,and only if the origin 0 can be represented as a positive convex combination of G.So we develop a constructive procedure called ri-simplex algorithm to find a positive convex combination of G when it has relative form closure.Form closure is considered as a special case of relative form closure,when the grasp G can affinely span the whole space,while partly relative form closure is referred to as form closed relative to a subset G1 of G. | XIONG YouLun XIONG Tao WANG YuHui | 2014 | Science China(Technological Sciences)2014，57，7： | 0 |
| 5 | White matter regeneration induced by aligned fibrin nanofiber hydrogel contributes to motor functional recovery in canine T12 spinal cord injury显示文摘A hierarchically aligned fibrin hydrogel(AFG)that possesses soft stiffness and aligned nanofiber structure has been successfully proven to facilitate neuroregeneration in vitro and in vivo.However,its potential in promoting nerve regeneration in large animal models that is critical for clinical translation has not been sufficiently specified.Here,the effects of AFG on directing neuroregeneration in canine hemisected T12 spinal cord injuries were explored.Histologically obvious white matter regeneration consisting of a large area of consecutive,compact and aligned nerve fibers is induced by AFG,leading to a significant motor functional restoration.The canines with AFG implantation start to stand well with their defective legs from 3 to 4 weeks postoperatively and even effortlessly climb the steps from 7 to 8 weeks.Moreover,high-resolution multi-shot diffusion tensor imaging illustrates the spatiotemporal dynamics of nerve regeneration rapidly crossing the lesion within 4 weeks in the AFG group.Our findings indicate that AFG could be a potential therapeutic vehicle for spinal cord injury by inducing rapid white matter regeneration and restoring locomotion,pointing out its promising prospect in clinic practice. | Zheng Cao Weitao Man Yuhui Xiong Yi Guo Shuhui Yang Dongkang Liu He Zhao Yongdong Yang Shenglian Yao Chuzhong Li Lingyun Zhao Xiaodan Sun Hua Guo Guihuai Wang Xiumei Wang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
| 6 | Glutamate-releasing BEST1 channel is a new target for neuroprotection against ischemic stroke with wide time window显示文摘Many efforts have been made to understand excitotoxicity and develop neuroprotectants for the therapy of ischemic stroke.The narrow treatment time window is still to be solved.Given that the ischemic core expanded over days,treatment with an extended time window is anticipated.Bestrophin1(BEST1)belongs to a bestrophin family of calcium-activated chloride channels.We revealed an increase in neuronal BEST1 expression and function within the peri-infarct from 8 to 48 h after ischemic stroke in mice.Interfering the protein expression or inhibiting the channel function of BEST1 by genetic manipulation displayed neuroprotective effects and improved motor functional deficits.Using electrophysiological recordings,we demonstrated that extrasynaptic glutamate release through BEST1 channel resulted in delayed excitotoxicity.Finally,we confirmed the therapeutic efficacy of pharmacological inhibition of BEST1 during 6—72 h post-ischemia in rodents.This delayed treatment prevented the expansion of infarct volume and the exacerbation of neurological functions.Our study identifies the glutamatereleasing BEST1 channel as a potential therapeutic target against ischemic stroke with a wide time window. | Shuai Xiong Hui Xiao Meng Sun Yunjie Liu Ling Gao Ke Xu Haiying Liang Nan Jiang Yuhui Lin Lei Chang Haiyin Wu Dongya Zhu Chunxia Luo | 2023 | Acta Pharmaceutica Sinica B2023，13，7： | 0 |
| 7 | Pyrocincholic acid 3β-O-β-D-quinovopyranosyl-28-O-β-Dglucopyranoside suppresses adipogenesis and regulates lipid metabolism in 3T3-L1 adipocytes显示文摘Obesity is crucially involved in many metabolic diseases,such as type 2 diabetes,cardiovascular disease and cancer.Regulating the number or size of adipocytes has been suggested to be a potential treatment for obesity.In this study,we investigated the effect of pyrocincholic acid 3β-O-β-D-quinovopyranosyl-28-O-β-D-glucopyranoside(PAQG),a 27-nor-oleanolic acid saponin extracted from Metadina trichotoma,on adipogenesis and lipid metabolism in 3T3-L1 adipocytes.The 3T3-L1 pre-adipocytes were incubated with vehicle or PAQG for 6 days in differentiation process.PAQG significantly reduced the adipogenesis,adiponectin secretion and the expression level of key transcription factors related to adipogenesis,such as PPARc,C/EBPb,C/EBPa,and FABP4.Moreover,PAQG increased the levels of FFA and glycerol in medium and reduced TG level in mature adipocytes.Interestingly,PAQG not only promoted the activation of AMPK and genes involved in fatty oxidation including PDK4 and CPT1a,but also inhibited those genes involved in fatty acid biosynthesis,such as SREBP1c,FAS,ACCa and SCD1.In conclusion,PAQG inhibits the differentiation and regulates lipid metabolism of 3T3-L1 cells via AMPK pathway,suggesting that PAQG may be a novel and promising natural product for the treatment of obesity and hyperlipidemia. | Li Peng Yanting Lu Yuhui Xu Jing Hu Fang Wang Yumei Zhang Wenyong Xiong | 2017 | Natural Products and Bioprospecting2017，7，3： | 0 |
