| 1 | Exosomes: roles and therapeutic potential in osteoarthritis显示文摘Exosomes participate in many physiological and pathological processes by regulating cell–cell communication, which are involved in numerous diseases, including osteoarthritis(OA). Exosomes are detectable in the human articular cavity and were observed to change with OA progression. Several joint cells, including chondrocytes, synovial fibroblasts, osteoblasts, and tenocytes, can produce and secrete exosomes that influence the biological effects of targeted cells. In addition, exosomes from stem cells can protect the OA joint from damage by promoting cartilage repair, inhibiting synovitis, and mediating subchondral bone remodeling.This review summarizes the roles and therapeutic potential of exosomes in OA and discusses the perspectives and challenges related to exosome-based treatment for OA patients in the future. | Zhenhong Ni Siru Zhou Song Li Liang Kuang Hangang Chen Xiaoqing Luo Junjie Ouyang Mei He Xiaolan Du Lin Chen | 2020 | Bone Research2020，8，2： | 10 |
| 2 | Inhibition of aberrant Hif1αactivation delays intervertebral disc degeneration in adult mice显示文摘The intervertebral disc(IVD) is the largest avascular tissue. Hypoxia-inducible factors(HIFs) play essential roles in regulating cellular adaptation in the IVD under physiological conditions. Disc degeneration disease(DDD) is one of the leading causes of disability, and current therapies are ineffective. This study sought to explore the role of HIFs in DDD pathogenesis in mice. The findings of this study showed that among HIF family members, Hif1α was significantly upregulated in cartilaginous endplate(EP) and annulus fibrosus(AF) tissues from human DDD patients and two mouse models of DDD compared with controls. Conditional deletion of the E3 ubiquitin ligase Vhl in EP and AF tissues of adult mice resulted in upregulated Hif1α expression and age-dependent IVD degeneration. Aberrant Hif1α activation enhanced glycolytic metabolism and suppressed mitochondrial function. On the other hand, genetic ablation of the Hif1α gene delayed DDD pathogenesis in Vhl-deficient mice. Administration of 2-methoxyestradiol(2ME2), a selective Hif1α inhibitor, attenuated experimental IVD degeneration in mice. The findings of this study show that aberrant Hif1α activation in EP and AF tissues induces pathological changes in DDD, implying that inhibition of aberrant Hif1α activity is a potential therapeutic strategy for DDD. | Zuqiang Wang Hangang Chen Qiaoyan Tan Junlan Huang Siru Zhou Fengtao Luo Dali Zhang Jing Yang Can Li Bo Chen Xianding Sun Liang Kuang Wanling Jiang Zhenhong Ni Quan Wang Shuai Chen Xiaolan Du Di Chen Chuxia Deng Liangjun Yin Lin Chen Yangli Xie | 2022 | Bone Research2022，10，1： | 1 |
| 3 | Anchoring polysulfide with artificial solid electrolyte interphase for dendrite-free and low N/P ratio Li-S batteries显示文摘Lithium sulfur batteries are regarded as a promising candidate for high-energy-density energy storage devices.However,the lithium metal anode in lithium-sulfur batteries encounters the problem of lithium dendrites and lithium metal consumption caused by polysulfide corrosion.Herein we design a dualfunction PMMA/PPC/LiNO3composite as an artificial solid electrolyte interphase(PMCN-SEI)to protect Li metal anode.This SEI offers multiple sites of C=O for polysulfide anchoring to constrain corrosion of Li metal anode.The lithiated polymer group and Li3N in PMCN-SEI can homogenize lithium-ion deposition behavior to achieve a dendrite-free anode.As a result,the PMCN-SEI protected Li metal anode enables the Li||Li symmetric batteries to maintain over 300 cycles(1300 h)at a capacity of 5 m Ah cm^(-2),corresponding to a cumulative capacity of 3.25 Ah cm^(-2).Moreover,Li-S batteries assembled with 20μm of Li metal anode(N/P=1.67)still deliver an initial capacity of 1166 m A h g-1at 0.5C.Hence,introducing polycarbonate polymer/inorganic composite SEI on Li provides a new solution for achieving the high energy density of Li-S batteries. | Wei Lu Zhao Wang Guiru Sun Shumin Zhang Lina Cong Lin Lin Siru Chen Jia Liu Haiming Xie Yulong Liu | 2023 | Journal of Energy Chemistry2023，，5： | 1 |
| 4 | Nicotine and its metabolite cotinine target MD2 and inhibit TLR4 signaling显示文摘Nicotine is the principal alkaloid of tobacco often manufactured into cigarettes and belongs to a highly addictive class of drugs.Nicotine attenuates the neuroinflammation induced by microglial activation.However,the molecular target(s)underlying anti-inflammatory action of nicotine has not been fully understood.Considering the psychoactive substances morphine,cocaine,and methamphetamine act as xenobiotic-associated molecular patterns and can be specifically sensed by the innate immune receptor Toll-like receptor 4(TLR4),here we sought to delineate whether nicotine and/or its metabolite cotinine may be recognized by the innate immune system via myeloid differentiation protein 2(MD2). | Hongyuan Li Yinghua Peng Cong Lin Xiaozheng Zhang Tianshu Zhang Yibo Wang Yuanpeng Li Siru Wu Hongshuang Wang Mark RHutchinson Linda RWatkins Xiaohui Wang | 2021 | The Innovation2021，2，2： | 0 |
| 5 | 20μm Li metal modified with phosphate rich polymer-inorganic interphase applied in commercial carbonate electrolyte显示文摘Li metal batteries are supposed to reach real application in order to fulfill the high-energy density requirement of energy storage system.Unfortunately,the commonly used carbonate electrolyte react with pristine Li,which result in short lifetime of lithium metal battery.To alleviate the side reactions of Li metal with liquid electrolyte,here we propose a phosphate rich polymer-inorganic layer as an interphase.Due to the inert properties of lithium phosphate derived from LiPO_(2)F_(2)and poly-ether,the side-reaction of carbonate solvent are prevented.As a result,lithium metal anode sustains for 800 cycles in symmetrical cell test under 1 m A cm^(-2).Even under strict condition(20μm Li,capacity ratio N/P=2.3,electrolyte/active material=3μL mg^(-1)),coin cell test still runs stable for 150 cycles with high Coulombic efficiency.Furthermore,both LiFePO_(4)and LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)pouch cell under 5μL m A^(-1)h^(-1)condition also exhibit good stability at 0.5 C and 2 C rate.With this approach,high-energy and high-power Li metal batteries are approaching to real application in the near future. | Lin Lin Wei Lu Feipeng Zhao Siru Chen Jia Liu Haiming Xie Yulong Liu | 2023 | Journal of Energy Chemistry2023，，1： | 0 |
| 6 | gcCov:Linked open data for global coronavirus studies显示文摘Impact Statement We present a method of mapping data from publicly available genomics and publication resources to the Resource Description Framework(RDF)and implement a server to publish linked open data(LOD).As one of the largest and most comprehensive semantic databases about coronaviruses,the resulted gcCov database demonstrates the capability of using data in the LOD framework to promote correlations between genotypes and phenotypes.These correlations will be helpful for future research on fundamental viral mechanisms and drug and vaccine designs. | Wenyu Shi Guomei Fan Zhihong Shen Chuan Hu Juncai Ma Yuanchun Zhou Zhen Meng Songnian Hu Yuhai Bi Liang Wang Haiying Yu Siru Lin Xiuqiang Sun Xinjiao Zhang Dongmei Liu Qinlan Sun Linhuan Wu | 2022 | mLife2022，1，1： | 0 |
