| 1 | Infection with novel coronavirus(SARS-CoV-2)causes pneumonia in Rhesus macaques显示文摘The 2019 novel coronavirus(SARS-CoV-2)outbreak is a major challenge for public health.SARS-CoV-2 infection in human has a broad clinical spectrum ranging from mild to severe cases,with a mortality rate of^6.4%worldwide(based on World Health Organization daily situation report).However,the dynamics of viral infection,replication and shedding are poorly understood.Here,we show that Rhesus macaques are susceptible to the infection by SARS-CoV-2.After intratracheal inoculation,the first peak of viral RNA was observed in oropharyngeal swabs one day post infection(1 d.p.i.),mainly from the input of the inoculation,while the second peak occurred at 5 d.p.i.,which reflected on-site replication in the respiratory tract.Histopathological observation shows that SARS-CoV-2 infection can cause interstitial pneumonia in animals,characterized by hyperemia and edema,and infiltration of monocytes and lymphocytes in alveoli.We also identified SARS-CoV-2 RNA in respiratory tract tissues,including trachea,bronchus and lung;and viruses were also re-isolated from oropharyngeal swabs,bronchus and lung,respectively.Furthermore,we demonstrated that neutralizing antibodies generated from the primary infection could protect the Rhesus macaques from a second-round challenge by SARS-CoV-2.The non-human primate model that we established here provides a valuable platform to study SARS-CoV-2 pathogenesis and to evaluate candidate vaccines and therapeutics. | Chao Shan Yan-Feng Yao Xing-Lou Yang Yi-Wu Zhou Ge Gao Yun Peng Lian Yang Xue Hu Jin Xiong Ren-Di Jiang Hua-Jun Zhang Xiao-Xiao Gao Cheng Peng Juan Min Ying Chen Hao-Rui Si Jia Wu Peng Zhou Yan-Yi Wang Hong-Ping Wei Wei Pang Zheng-Fei Hu Long-Bao Lv Yong-Tang Zheng Zheng-Li Shi Zhi-Ming Yuan | 2020 | Cell Research2020，30，8： | 19 |

| 4 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

| 6 | 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 |
| 7 | Research progresses of cathodic hydrogen evolution in advanced lead–acid batteries显示文摘Integrating high content carbon into the negative electrodes of advanced lead–acid batteries effectively eliminates the sulfation and improves the cycle life,but brings the problem of hydrogen evolution,which increases inner pressure and accelerates the water loss.In this review,the mechanism of hydrogen evolution reaction in advanced lead–acid batteries,including lead–carbon battery and ultrabattery,is briefly reviewed.The strategies on suppression hydrogen evolution via structure modifications of carbon materials and adding hydrogen evolution inhibitors are summarized as well.The review points out effective ways to inhibit hydrogen evolution and prolong the cycling life of advanced lead–acid battery,especially in high-rate partial-state-of-charge applications. | Feng Wang Chen Hu Min Zhou Kangli Wang Jiali Lian Jie Yan Shijie Cheng Kai Jiang | 2016 | Science Bulletin2016，61，6： | 8 |
| 8 | Decreased Average Albumin-to-Globulin Ratio During Radiotherapy Worsens the Prognosis of Esophageal Squamous Cell Carcinoma:Implications for Nutritional Management显示文摘Objective Malnutrition and cachexia are common in esophageal squamous cell carcinoma(ESCC)patients undergoing radiotherapy.This study evaluated how malnutrition-and cachexia-related indicators,including the albumin-to-globulin ratio(AGR),and their changes during radiotherapy predict the treatment outcomes.Methods We reviewed a total of 172 ESCC patients receiving radiotherapy(as a primary cohort)and performed a Cox regression analysis on potential prognostic factors,including the AGR,as well as the TNM stage and concomitant chemotherapy.A subsequent receiver operating characteristics(ROC)curve and Kaplan Meier survival analysis was performed for ESCC patients stratified by the average AGR cut-off point.Results In addition to the well-documented factors(i.e.TNM stage and concomitant chemotherapy),the average AGR was a significant prognostic factor for ESCC patients receiving radiotherapy.By plotting the ROC curve of the average AGR with regard to the ESCC prognosis,we obtained cut-off points for the overall patients(cut-off point:1.5,AUC:0.636),for patients with stageⅡ/Ⅲdisease(cut-off point:1.5,AUC:0.611),and for patients with stageⅣdisease(cut-off point:1.84,AUC:0.900).The ESCC patients with higher average AGR had a significantly more favorable OS compared with those with a lower average AGR.Notably,ESCC patients who had an increasingΔAGR during radiotherapy had a considerably more favorable OS compared with those with a decreasingΔAGR.All of these findings were reproducible in the validation cohort.Conclusion A lower average AGR is indicative of a poorer prognosis for ESCC patients following radiotherapy.Improving the nutritional status and preventing or ameliorating cachexia might contribute to improving the prognosis of ESCC patients. | Fen Cai Xiu Lian Zhang Xiao Ling Wu Ting Ting Zhuang Lei Huang Yi Fei Tu Yuan Yuan Lu Min Xia Jiang Qing Ying Zhang Yan Lin Chang Chun Ma | 2021 | Journal of Nutritional Oncology2021，6，2： | 8 |
| 9 | Malignant Transformation and Abnormal Expression of Eukaryotic Initiation Factor in Bronchial Epithelial Cells Induced by Cadmium Chloride显示文摘Objective To analyze the relationship between malignant transformation and abnormal expression of eukaryotic initiation factor 3 (eIF3 p36) in human bronchial epithelial (16HBE) cells induced by cadmium chloride (CdCl2). Methods 16HBE cells were treated several times with different concentrations of CdCl2. Tumorigenic potential of transformed cells was identified by assays for anchorage-independent growth in soft agar and for tumorigenicity in nude mice after the 35th passage. Total RNA was isolated from 16HBE cells induced by CdCl2, including non-transformed, Cd-transformed, and Cd-tumorigenic cell lines. Special primers for eIF3 p36 were designed and the expression of eIF3 mRNA in different cell lines was detected with fluorescent quantitative-polymerase chain reaction technique (FQ-PCR). Results The 35th passage of 16HBE cells transformed by CdCl2 exhibited overlapping growth. Compared with the non-transformed cells, colonies of transformed cell lines in soft agar showed statistically significant increases and dose-dependent effects (P<0.01). All Cd-induced transformed cell lines formed tumors in nude mice within 2 weeks of inoculation, but none of the mice injected with non-transformed cells showed tumors even after 3 weeks. All tumors were pathologically identified as poorly differentiated squamous cell carcinoma. The eIF3 p36 genes in different stages of 16HBE cells transformed by CdCl2 were elevated as compared with the non-transformed control (P<0.01), and the eIF3 expression increased with the degree of cell malignancy. Conclusion CdCl2 is capable of inducing morphological transformation in 16HBE cells and transformed cells are potentially tumorigenic. Over-expression of eIF3 p36 is positively correlated with malignant transformation of 16HBE cells induced by CdCl2 and may be one of the molecular mechanisms potentially responsible for carcinogenesis due to Cd. | YI-XIONG LEI LIAN WEI MIN WANG GEN-RONG WU MIN LI | 2008 | Biomedical and Environmental Sciences2008，21，4： | 7 |
| 10 | Short-term therapeutic outcomes of robotic-assisted laparoscopic radical prostatectomy for oligometastatic prostate cancer:a propensity score matching study显示文摘Background:The role of local treatment in oligometastatic prostate cancer(PCa)is gaining interest with the oligometastases hypothesis proposed and the improvement of various surgical methods and techniques.This study aimed to compare the short-term therapeutic outcomes of robotic-assisted laparoscopic radical prostatectomy(RALP)for oligometastatic prostate cancer(OPC)vs.localized PCa using propensity score matching.Methods:Totally 508 consecutive patients underwent RALP as a first-line treatment.The patients were divided into two groups according to oligometastatic state:the OPC group(n=41)or the localized PCa group(n=467).Oligometastatic disease was defined as the presence of two or fewer suspicious lesions.The association between the oligometastatic state and therapeutic outcomes of RALP was evaluated,including biochemical recurrence(BCR)and overall survival(OS).A Cox proportional hazards model was used to assess the possible risk factors for BCR.Results:Totally 41 pairs of patients were matched.The median operative time,the median blood loss,the overall positive surgical margin rate,the median post-operative hospital stays,and the post-operative urinary continence recovery rate between the two groups showed no statistical significance.The 4-year BCR survival rates of the OPC group and localized PCa group were 56.7%and 60.8%,respectively,without a significant difference(P=0.804).The 5-year OS rates were 96.3%and 100%,respectively(P=0.326).Additionally,the results of Cox regression showed that oligometastatic state was not an independent risk factor for BCR(P=0.682).Conclusions:Our findings supported the safety and effectiveness of RALP in OPC.Additionally,oligometastatic state and sites did not have an adverse effect on BCR independently. | Huan Chen Min Qu Bi-Jun Lian Hai-Feng Wang Yan Wang Zhen-Yang Dong Feng Zhu Zhen-Kai Shi Ze-Peng Jia Ying-Hao Sun Xu Gao | 2020 | Chinese Medical Journal2020，，2： | 7 |
| 11 | Floral traits and pollination system of Zygophyllum xanthoxylum in the managed and wild populations in an arid region of Northwest China显示文摘Zygophyllum xanthoxylum, which belongs to Sarcozygium of Zygophyllaceae, is one of the ecologically important species in Northwest China. In order to understand the pollination system of Z. xanthoxylum, we investigated the following characteristics of this species in the Urat Desert-grassland Research Station in western Inner Mongolia of China: flowering dynamics, pollen viability, pollen limitation, floral visitors and breeding system. The results showed that the flowering period and flowering peak were different between the wild and managed populations, being longer in the managed population. Z. xanthoxylum was pollen-limited, and pollen limitation was more intense in the wild population than in the managed population. Chalicodoma deserticola(Hymenoptera) was found to be the most frequent pollinator in the wild population, while Anthophora fulvitarsis(Hymenoptera) was the most frequent and effective visitor in the managed population. Out-crossing was dominant in the breeding system and self-pollination just played an assistant role to assure the reproduction of Z. xanthoxylum. | CHEN Min ZHAO Xueyong ZUO Xiao'an LIAN Jie ZHU Yangchun | 2015 | Journal of Arid Land2015，7，4： | 7 |
| 12 | Dalbavancin binds ACE2 to block its interaction with SARS-CoV-2 spike protein and is effective in inhibiting SARS-CoV-2 infection in animal models显示文摘Infection with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has caused a pandemic worldwide.Currently,however,no effective drug or vaccine is available to treat or prevent the resulting coronavirus disease 2019(COVID-19).Here,we report our discovery of a promising an ti-COVID-19 drug can didate,the lipoglycopeptide antibiotic dalbava ncin,based on virtual screening of the FDA-approved peptide drug library combined with in vitro and in vivo functional antiviral assays.Our results showed that dalbavancin directly binds to human angiotensin-converting enzyme 2(ACE2)with high affinity,thereby blocking its interaction with the SARS-CoV-2 spike protein.Furthermore,dalbavancin effectively prevents SARS-CoV-2 replication in Vero E6 cells with an EC50 of~12 nM.In both mouse and rhesus macaque models,viral replication and histopathological injuries caused by SARS-CoV-2 infection are significantly inhibited by dalbavancin administration.Given its high safety and long plasma half-life(8-10 days)shown in previous clinical trials,our data indicate that dalbavancin is a promising anti-COVID-19 drug candidate. | Gan Wang Meng-Li Yang Zi-Lei Duan Feng-Liang Liu Lin Jin Cheng-Bo Long Min Zhang Xiao-Peng Tang Ling Xu Ying-Chang Li Peter Muiruri Kamau Lian Yang Hong-Qi Liu Jing-Wen Xu Jie-Kai Chen Yong-Tang Zheng Xiao-Zhong Peng Ren Lai | 2021 | Cell Research2021，31，1： | 6 |

| 15 | Spiral Field Generation in Smith-Purcell Radiation by Helical Metagratings显示文摘Moving electrons interacting with media can give rise to electromagnetic radiations and has been emerged as a promising platform for particle detection,spectroscopies,and free-electron lasers.In this letter,we investigate the Smith-Purcell radiation from helical metagratings,chiral structures similar to deoxyribonucleic acid(DNA),in order to understand the interplay between electrons,photons,and object chirality.Spiral feld patterns can be generated while introducing a gradient azimuthal phase distribution to the induced electric dipole array at the cylindrical interface.Experimental measurements show efcient control over angular momentum of the radiated feld at microwave regime,utilizing a phased electromagnetic dipole array to mimic moving charged particles.Te angular momentum of the radiated wave is determined solely by the handedness of the helical structure,and it thus serves as a potential candidate for the detection of chiral objects.Our fndings not only pave a way for design of orbital angular momentum free-electron lasers but also provide a platform to study the interplay between swif electrons with chiral objects. | Liqiao Jing Zuojia Wang Xiao Lin Bin Zheng Su Xu Lian Shen Yihao Yang Fei Gao Min Chen Hongsheng Chen | 2019 | Research2019，，1： | 4 |

| 17 | Stable Carbon Isotopic Composition of Black Carbon in Surface Soil as a Proxy for Reconstructing Vegetation on the Northern Slope of the Qinling Mountains显示文摘Because of the unique geographical location and important ecological effect of the Qinling Mountains,reconstruction of its vegetation and climate needs comprehensive research.We need to consider a multiple-proxy approach to gain more information on recovering the paleovegetation and climate in the Qinling Mountains.Black carbon(BC)is produced by the incomplete combustion of vegetation and fossil fuels,and is a good proxy,recording paleoenvironmental information.However,in the Qinling Mountains,what are the characteristics of the BC,and whether BC stable carbon isotope(δ^(13)C_(BC))can be used as a new proxy to study ancient vegetation,still need further study.In order to establish a sound basis for studying paleoenvironmental by BC proxy in the Qinling Mountains,we carried out systematic and detailed study on modern process of BC on the northern slope of the mountains.We analyzed stable carbon isotopes and carbon concentration of organic carbon(%SOC,δ^(13)C_(SOC))and BC(%BC,δ^(13)C_(BC)),and identified the pollen assemblages from systematically sampled surface soil.The results show that the calculated ratio of C_4 plants in the vegetation(%C_4)based on theδ^(13)C_(SOC)data reflects a similar distribution of C_4 plants in the surface vegetation and the pollen assemblage.Theδ^(13)C_(BC)values have a strong positive correlation withδ^(13)C_(SOC)values,and their difference(△^(13)C_(SOC-BC))is in the low range.These data indicate thatδ^(13)C_(BC)andδ^(13)C_(SOC)have very similar characteristics.Surface soilδ^(13)C_(BC)values can indicate surface vegetation as effectively asδ^(13)C_(SOC)values,and theδ^(13)C_(BC)proxy can be used effectively in paleovegetational research in the northern slope of Qinling Mountains. | LIU Lian HUANG Min LIU Zhiqiang | 2016 | Acta Geologica Sinica(English Edition)2016，90，1： | 4 |

| 19 | Establishment of Real-Time TaqMan-Fluorescence Quantitative RT-PCR Assay for Detection and Quantification of Porcine Lipoprotein Lipase mRNA显示文摘Porcine lipoprotein lipase (LPL) cDNA was cloned as the standard for real-time quantifying LPL mRNA and the TaqMan-fluorescence quantitative PCR assay for detection was established. The total RNA extracted from Longissimus dorsi of porcine was reverse-transcribed to cDNA. LPL cDNA was ligated with pGM-T vector and transformed into Escherichia coli TOP10. Plasmid DNA extracted from positive clones was verified by PCR amplification and sequenced. LPL was amplified by real-time fluorescence quantitative PCR from the plasmid DNA. The concentration of DNA template purified was detected by analyzing absorbance in 260 nm and then the combined plasmid was diluted to series as standard for fluorescence quantitative PCR (FQ-PCR). The method of LPL mRNA real-time PCR was well established, which detected as low as 103 with the linear range 103 to 1010 copies. The standard curves showed high correlations (R2 = 0.9871). A series of standards for real-time PCR analysis have been constructed successfully, and real-time TaqMan-fluorescence quantitative RT-PCR is reliable to quantitatively evaluate FQ-PCR mRNA in L. dorsi of porcine. | LIAN Hong-xia LU De-xun GAO Min | 2009 | Agricultural Sciences in China2009，8，10： | 4 |
