| 1 | CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19. | Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 9 |

| 3 | Visfatin Protects Rat Pancreatic β-cells against IFN-γ-Induced Apoptosis through AMPK and ERK1/2 Signaling Pathways显示文摘Objective Interferon-γ(IFN-γ) plays an important role in apoptosis and was shown to increase the risk of diabetes. Visfatin, an adipokine, has anti-diabetic, anti-tumor, and regulating inflammatory properties. In this study we investigated the effect of visfatin on IFN-γ-induced apoptosis in rat pancreatic β-cells. Methods The RINm5F(rat insulinoma cell line) cells exposed to IFN-γ were treated with or without visfatin. The viability and apoptosis of the cells were assessed by using MTT and flow cytometry. The expressions of m RNA and protein were detected by using real-time PCR and western blot analysis. Results The exposure of RINm5 F cells to IFN-γ for 48 h led to increased apoptosis percentage of the cells. Visfatin pretreatment significantly increased the cell viability and reduced the cell apoptosis induced by IFN-γ. IFN-γ-induced increase in expression of p53 m RNA and cytochrome c protein, decrease in m RNA and protein levels of anti-apoptotic protein Bcl-2 were attenuated by visfatin pretreatment. Visfatin also increased AMPK and ERK1/2 phosphorylation and the anti-apoptotic action of visfatin was attenuated by the AMPK and ERK1/2 inhibitor. Conclusion These results suggested that visfatin protected pancreatic islet cells against IFN-γ-induced apoptosis via mitochondria-dependent apoptotic pathway. The anti-apoptotic action of visfatin is mediated by activation of AMPK and ERK1/2 signaling molecules. | XIANG Ruo Lan MEI Mei SU Yun Chao LI Li WANG Jin Yu WU Li Ling | 2015 | Biomedical and Environmental Sciences2015，28，3： | 7 |
| 4 | CD147 antibody specifically and effectively inhibits infection and cytokine storm of SARS-CoV-2 and its variants delta,alpha,beta,and gamma显示文摘SARS-CoV-2 mutations contribute to increased viral transmissibility and immune escape,compromising the effectiveness of existing vaccines and neutralizing antibodies.An in-depth investigation on COVID-19 pathogenesis is urgently needed to develop a strategy against SARS-CoV-2 variants.Here,we identified CD147 as a universal receptor for SARS-CoV-2 and its variants.Meanwhile,Meplazeumab,a humanized anti-CD147 antibody,could block cellular entry of SARS-CoV-2 and its variants-alpha,beta,gamma,and delta,with inhibition rates of 68.7,75.7,52.1,52.1,and 62.3%at 60μg/ml,respectively.Furthermore,humanized CD147 transgenic mice were susceptible to SARS-CoV-2 and its two variants,alpha and beta.When infected,these mice developed exudative alveolar pneumonia,featured by immune responses involving alveoli-infiltrated macrophages,neutrophils,and lymphocytes and activation of IL-17 signaling pathway.Mechanistically,we proposed that severe COVID-19-related cytokine storm is induced by a'spike protein-CD147-CyPA signaling axis':Infection of SARS-CoV-2 through CD147 initiated the JAK-STAT pathway,which further induced expression of cyclophilin A(CyPA);CyPA reciprocally bound to CD147 and triggered MAPK pathway.Consequently,the MAPK pathway regulated the expression of cytokines and chemokines,which promoted the development of cytokine storm.Importantly,Meplazumab could effectively inhibit viral entry and inflammation caused by SARS-CoV-2 and its variants.Therefore,our findings provided a new perspective for severe COVID-19-related pathogenesis.Furthermore,the validated universal receptor for SARS-CoV-2 and its variants can be targeted for COVID-19 treatment. | Jiejie Geng Liang Chen Yufeng Yuan Ke Wang Youchun Wang Chuan Qin Guizhen Wu Ruo Chen Zheng Zhang Ding Wei Peng Du Jun Zhang Peng Lin Kui Zhang Yongqiang Deng Ke Xu Jiangning Liu Xiuxuan Sun Ting Guo Xu Yang Jiao Wu Jianli Jiang Ling Li Kun Zhang Zhe Wang Jing Zhang Qingguo Yan Hua Zhu Zhaohui Zheng Jinlin Miao Xianghui Fu Fengfan Yang Xiaochun Chen Hao Tang Yang Zhang Ying Shi Yumeng Zhu Zhuo Pei Fei Huo Xue Liang Yatao Wang Qingyi Wang Wen Xie Yirong Li Mingyan Shi Huijie Bian Ping Zhu Zhi-Nan Chen | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |

| 6 | Formation of ZrB2in MgO-C Composite Materials Using In-Situ Synthesis Method显示文摘ZrB2 in MgO-C composite materials obtained by both microwave sintering synthesis and in-situ reaction at lower temperature was investigated. The test result shows that 66.67% of reactant changed into ZrB2, and the other form Al2O3, which could optimize the properties of carbon-containing materials. Therefore, the method of in-situ synthesizing ZrB2 acting as antioxidant in carbon-containing materials is considered as one of best ways to reduce the cost and ZrB2 as refractories is used on a large-scale. | LI Lin HONG Yan ruo SUN Jia-lin HE Zhi-yong PENG Xiao-yan | 2006 | Journal of Iron and Steel Research(International)2006，13，1： | 3 |
| 7 | Novel guanidinium-based ionic liquids as stationary phases for capillary gas chromatography显示文摘The present study describes guanidinium-based ionic liquids(GBILs) as stationary phases for capillary gas chromatography (CGC) and to the best of our knowledge,no related reports are available up to now.In this study,a hexaalkylguanidinium ionic liquid(DOTMG-NTf_2) was synthesized and coated statically onto capillary columns.Selectivity of the stationary phase was evaluated by separating Grob test mixture,test mixture,alcohols mixture,and fatty acid methyl esters mixture,and thermal stability was investigated as well.The present study demonstrates that GBILs as CGC stationary phases exhibit satisfactory selectivity and thermal stability and have a great potential as new candidates for CGC stationary phases. | Li Zhen Qiao Kai Lu Mei Ling Qi Ruo Nong Fu | 2010 | Chinese Chemical Letters2010，21，9： | 3 |
| 8 | Amperometric Determination of lndole-3-acetic Acid Based on Platinum Nanowires and Carbon Nanotubes显示文摘Platinum nanowire (PtNW) can be grown by electrodeposition in polycarbonate membrane, with the average diameter of the nanowires about 250 nm. The PtNW and multiwalled carbon nanotubes (CNT) are then dispersed into chitosan (CHIT) solution. The resulting PtNW-CNT-CHIT material brings new capabilities for electrochemical devices by using the synergistic action of the electrocatalytic activity of PtNW and CNT. By dropping the PtNW-CNT-CHIT film onto the glassy carbon (GC) electrode surface, and after evaporation an amperometric sensor for the determination of indole-3-acetic acid (IAA) was developed. The oxidation current of IAA increased significantly at the PtNW-CNT-CHIT film coated GC electrode, in contrast to that at the CNT-CHIT modified GC. The linear response of the sensor is from 50 ng/ml to 50 μg/ml with a detection limit of 25 ng/mL. | Ruo Zhong WANG Lang Tao XIAO Ming Hui YANG Jun Hui DING Feng Li QU Guo Li-SHEN | 2006 | Chinese Chemical Letters2006，17，12： | 3 |

| 10 | Safety and efficacy of meplazumab in healthy volunteers and COVID-19 patients: a randomized phase 1 and an exploratory phase 2 trial显示文摘Recent evidence suggests that CD147 serves as a novel receptor for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection.Blocking CD147 via anti-CD147 antibody could suppress the in vitro SARS-CoV-2 replication.Meplazumab is a humanized anti-CD147 IgG_(2) monoclonal antibody,which may effectively prevent SARS-CoV-2 infection in coronavirus disease 2019(COVID-19)patients.Here,we conducted a randomized,double-blinded,placebo-controlled phase 1 trial to evaluate the safety,tolerability,and pharmacokinetics of meplazumab in healthy subjects,and an open-labeled,concurrent controlled add-on exploratory phase 2 study to determine the efficacy in COVID-19 patients.In phase 1 study,59 subjects were enrolled and assigned to eight cohorts,and no serious treatment-emergent adverse event(TEAE)or TEAE grade≥3 was observed.The serum and peripheral blood Cmax and area under the curve showed non-linear pharmacokinetic characteristics.No obvious relation between the incidence or titer of positive anti-drug antibody and dosage was observed in each cohort.The biodistribution study indicated that meplazumab reached lung tissue and maintained>14 days stable with the lung tissue/cardiac blood-pool ratio ranging from 0.41 to 0.32.In the exploratory phase 2 study,17 COVID-19 patients were enrolled,and 11 hospitalized patients were involved as concurrent control.The meplazumab treatment significantly improved the discharged(P=0.005)and case severity(P=0.021),and reduced the time to virus negative(P=0.045)in comparison to the control group.These results show a sound safety and tolerance of meplazumab in healthy volunteers and suggest that meplazumab could accelerate the recovery of patients from COVID-19 pneumonia with a favorable safety profile. | Huijie Bian Zhao-Hui Zheng Ding Wei Aidong Wen Zheng Zhang Jian-Qi Lian Wen-Zhen Kang Chun-Qiu Hao Jing Wang Rong-Hua Xie Ke Dong Jie-Lai Xia Jin-Lin Miao Wen Kang Guoquan Li Di Zhang Mingru Zhang Xiu-Xuan Sun Likun Ding Kui Zhang Junfeng Jia Jin Ding Zhiqin Li Yanyan Jia Lin-Na Liu Zhe Zhang Zhao-Wei Gao Hong Du Na Yao Qing Wang Ke Wang Jie-Jie Geng Bin Wang Ting Guo Ruo Chen Yu-Meng Zhu Li-Juan Wang Qian He Rui-Rui Yao Ying Shi Xiang-Min Yang Jian-Sheng Zhou Yi-Nan Ma Ya-Tao Wang Xue Liang Fei Huo Zhe Wang Yang Zhang Xu Yang Ye Zhang Lu-Hua Gao Ling Wang Xiao-Chun Chen Hao Tang Shuang-Shuang Liu Qing-Yi Wang Zhi-Nan Chen Ping Zhu | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 2 |

| 16 | Mechanism of Learning and Memory Impairment in Rats Exposed to Arsenic and/or Fluoride Based on Microbiome and Metabolome显示文摘Objective Arsenic(As) and fluoride(F) are two of the most common elements contaminating groundwater resources. A growing number of studies have found that As and F can cause neurotoxicity in infants and children, leading to cognitive, learning, and memory impairments. However, early biomarkers of learning and memory impairment induced by As and/or F remain unclear. In the present study, the mechanisms by which As and/or F cause learning memory impairment are explored at the multi-omics level(microbiome and metabolome).Methods We stablished an SD rats model exposed to arsenic and/or fluoride from intrauterine to adult period.Results Arsenic and/fluoride exposed groups showed reduced neurobehavioral performance and lesions in the hippocampal CA1 region. 16S rRNA gene sequencing revealed that As and/or F exposure significantly altered the composition and diversity of the gut microbiome, featuring the Lachnospiraceae_NK4A136_group, Ruminococcus_1, Prevotellaceae_NK3B31_group, [Eubacterium]_xylanophilum_group. Metabolome analysis showed that As and/or F-induced learning and memory impairment may be related to tryptophan, lipoic acid, glutamate, gamma-aminobutyric acidergic(GABAergic) synapse, and arachidonic acid(AA) metabolism. The gut microbiota, metabolites, and learning memory indicators were significantly correlated.Conclusion Learning memory impairment triggered by As and/or F exposure may be mediated by different gut microbes and their associated metabolites. | ZHANG Xiao Li YU Sheng Nan QU Ruo Di ZHAO Qiu Yi PAN Wei Zhe CHEN Xu Shen ZHANG Qian LIU Yan LI Jia GAO Yi LYU Yi YAN Xiao Yan LI Ben REN Xue Feng QIU Yu Lan | 2023 | Biomedical and Environmental Sciences2023，36，3： | 2 |
