| 4 | 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 |

| 6 | PdAg bimetallic electrocatalyst for highly selective reduction of CO2 with low COOH^* formation energy and facile CO desorption显示文摘For electrocatalytic reduction of CO2 to CO,the stabilization of intermediate COOH^* and the desorption of CO^* are two key steps.Pd can easily stabilize COOH^*,whereas the strong CO^* binding to Pd surface results in severe poisoning,thus lowering catalytic activity and stability for CO2 reduction.On Ag surface,CO^* desorbs readily,while COOH^* requires a relatively high formation energy,leading to a high overpotential.In light of the above issues,we successfully designed the PdAg bimetallic catalyst to circumvent the drawbacks of sole Pd and Ag.The PdAg catalyst with Ag-terminated surface not only shows a much lower overpotential(-0.55 V with CO current density of 1 mA/cm^2)than Ag(−0.76 V),but also delivers a CO/H2 ratio 18 times as high as that for Pd at the potential of-0.75 V vs.RHE.The issue of CO poisoning is significantly alleviated on Ag-terminated PdAg surface,with the stability well retained after 4h electrolysis at-0.75 V vs.RHE.Density functional theory(DFT)calculations reveal that the Ag-terminated PdAg surface features a lowered formation energy for COOH^* and weakened adsorption for CO^*,which both contribute to the enhanced performance for CO2 reduction. | Rui Lin Xuelu Ma Weng-Chon Cheong Chao Zhang Wei Zhu Jiajing Pei Kaiyue Zhang Bin Wang Shiyou Liang Yuxi Liu Zhongbin Zhuang Rong Yu Hai Xiao Jun Li Dingsheng Wang Qing Peng Chen Chen Yadong Li | 2019 | Nano Research2019，12，11： | 7 |

| 12 | Assessment of Interannual Sea Surface Salinity Variability and Its Effects on the Barrier Layer in the Equatorial Pacific Using BNU-ESM显示文摘As salinity stratification is necessary to form the barrier layer(BL), the quantification of its role in BL interannual variability is crucial. This study assessed salinity variability and its effect on the BL in the equatorial Pacific using outputs from Beijing Normal University Earth System Model(BNU-ESM) simulations. A comparison between observations and the BNU-ESM simulations demonstrated that BNU-ESM has good capability in reproducing most of the interannual features observed in nature. Despite some discrepancies in both magnitude and location of the interannual variability centers, the displacements of sea surface salinity(SSS), barrier layer thickness(BLT), and SST simulated by BNU-ESM in the equatorial Pacific are realistic. During El Ni n?o, for example, the modeled interannual anomalies of BLT, mixed layer depth, and isothermal layer depth, exhibit good correspondence with observations, including the development and decay of El Ni n?o in the central Pacific, whereas the intensity of the interannual variabilities is weaker relative to observations. Due to the bias in salinity simulations, the SSS front extends farther west along the equator, whereas BLT variability is weaker in the central Pacific than in observations. Further, the BNU-ESM simulations were examined to assess the relative effects of salinity and temperature variability on BLT. Consistent with previous observation-based analyses, the interannual salinity variability can make a significant contribution to BLT relative to temperature in the western-central equatorial Pacific. | Hai ZHI Rong-Hua ZHANG Fei ZHENG Pengfei LIN Lanning WANG Peng YU | 2016 | Advances in Atmospheric Sciences2016，33，3： | 2 |
| 13 | Interannual Salinity Variability in the Tropical Pacific in CMIP5 Simulations显示文摘Salinity variability and its causes in the tropical Pacific are analyzed using observations, reanalysis products and model simulations. The mixed-layer salinity(MLS) budget analyses from observations and reanalysis products indicate that its interannual evolution is closely related to ENSO and is predominantly governed by surface forcing and surface advection in the western-central equatorial Pacific. It is found that the observed MLS tendency leads Nin?o3.4 by about 12 months due to the effect of negative freshwater flux(evaporation minus precipitation). These observation-based analyses are used to evaluate the corresponding simulation using GFDL-ESM2 M. It is evident that the model can simulate the spatiotemporal variations of MLS with some discrepancies compared to observations. In the warm pool of the equatorial Pacific the MLS tendency in the model is sensitive to ocean dynamics, however model biases cause the tendency to be underestimated. In particular, the freshwater flux is overestimated while the ocean surface zonal current and vertical velocity at the base of the mixed layer are underestimated. Due to model biases in representing the related physics, the effects of surface forcing on the simulated MLS budget are overestimated and those of subsurface and surface advection are relatively weak. Due to weaker surface advection and subsurface forcing than observed, the simulated compensations for surface forcing are suppressed, and the simulated MLS tendency that leads Nin?o3.4 by 8–10 months, which is shorter than the observed lead time. These results are useful for the interpretation of observational analyses and other model simulations in the tropical Pacific. | Hai ZHI Rong-Hua ZHANG Pengfei LIN Peng YU Rong-Hua ZHANG | 2019 | Advances in Atmospheric Sciences2019，36，4： | 2 |
| 14 | Silk Fibroin‑Based Wearable All‑Fiber Multifunctional Sensor for Smart Clothing显示文摘Wearable sensing technology enables the interaction between the physical world and the digital world,as takes an irreplaceable role in development of the Internet of Things(IoT),and artificial intelligence(AI).However,increasing requirements posed by rapid development of wearable electronic information technology bring about many for wearable sensing technology,such as the demands for ultrahigh flexibility,air permeability,excellent biocompatibility,and multifunctional integration.Herein,we propose a wearable all-fiber multifunctional sensor(AFMS)based on a biocompatible material,i.e.,silk fibroin.A simple two-layer configuration of a silk fiber film and an interdigital Ag nanowires(AgNWs)electrode was designed to construct the AFMS,in which silk fibroin simultaneously serves as a fundamental supporting component and a functional sensing component.Electrospinning and spray coating technologies were introduced to process the silk fiber film and the AgNWs electrode.The all-fiber configuration allows AFMS to possess ultrahigh flexibility and good air permeability,and silk fibroin enables the AFMS to have excellent biocompatibility.More importantly,benefiting from the all-fiber structure and the environmentally sensitive dielectric property of silk fibroin,the AFMS presented multiple sensing characteristics,including pressure sensing,temperature sensing,and humidity sensing.Among them,the pressure sensing function reached a high sensitivity of 2.27 pF/kPa(7.5%/kPa)and a remarkable resolution of~26 Pa in the low pressure range.Additionally,the outstanding mechanical reliability and sensing stability of AFMS were proven by a systematic experiment.In addition,the AFMS was successfully applied for smart mask for breathing monitoring and a smart glove for bending angle recognition of finger joints.Multiple sensing characteristics combined with prominent fundamental features enable the AFMS tremendous potential in the smart sensing field,e.g.,smart clothing. | Dan‑Liang Wen Yu‑Xing Pang Peng Huang Yi‑Lin Wang Xin‑Ran Zhang Hai‑Tao Deng Xiao‑Sheng Zhang | 2022 | Advanced Fiber Materials2022，4，4： | 2 |

| 17 | First Report in China on the Identification and Drug Sensitivity of Mycobacterium elephantis Isolated from the Milk of a Cow with Mastitis显示文摘Objective In this study, milk from a cow with mastitis was analyzed to determine the presence of mycobacterial infection. Milk quality and security problems pertaining to the safe consumption of dairy products were also discussed in this study. Methods Milk was preprocessed with 4% Na OH. Then, mycobacteria were isolated from the milk sample on L-J medium. The isolate was identified using multiple loci Polymerase Chain Reaction(PCR) and multi-locus sequence analysis with 16 S r RNA, sod A, hsp65, and ITS genes. The drug sensitivity of the isolate to 27 antibiotics was tested through alamar blue assay. Results Smooth, moist, pale yellow colonies appeared on the L-J medium within a week after inoculation. Based on the results of multiple loci PCR analysis, the isolate was preliminarily identified as non-tuberculous mycobacteria. The 16 S r RNA, Sod A, hsp65, and ITS gene sequences of the isolate exhibited 99%, 99%, 99%, and 100% similarities, respectively, with those of the published reference strains of Mycobacterium elephantis(M. elephantis). The drug sensitivity results showed that the strain is resistant to isoniazid, p-aminosalicylic acid, and trimesulf but is sensitive to ofloxacin, rifampicin, amikacin, capreomycin, moxifloxacin, kanamycin, levofloxacin, cycloserine, ethambutol, streptomycin, tobramycin, rifabutin, ciprofloxacin, linezolid, cefoxitin, clarithromycin, and minocycline. Conclusion To the best of our knowledge, this study is initially to report the isolation of M. elephantis from the milk of a cow with mastitis in China. | JI Ling Yun XU Dong Lei YIN Shu Peng LIU Hai Can LI Gui Lian JIANG Yi WEI Jian Hao ZENG Hao LOU Yong Liang LYU Jian Xin WAN Kang Lin | 2017 | Biomedical and Environmental Sciences2017，30，7： | 1 |
