| 1 | A Novel Coronavirus Genome Identified in a Cluster of Pneumonia Cases--Wuhan,China 2019−2020显示文摘Emerging and re-emerging pathogens are great challenges to the public health(1).A cluster of pneumonia cases with an unknown cause occurred in Wuhan starting on December 21,2019.As of January 20,2020,a total of 201 cases of pneumonia in China have been confirmed.A team of professionals from the National Health Commission and China CDC conducted epidemiological and etiological investigations.On January 3,2020,the first complete genome of the novelβgenus coronaviruses(2019-nCoVs)was identified in samples of bronchoalveolar lavage fluid(BALF)from a patient from Wuhan by scientists of the National Institute of Viral Disease Control and Prevention(IVDC)through a combination of Sanger sequencing,Illumina sequencing,and nanopore sequencing.Three distinct strains have been identified,the virus has been designated as 2019-nCoV,and the disease has been subsequently named novel coronavirus-infected pneumonia(NCIP). | Wenjie Tan Xiang Zhao Xuejun Ma Wenling Wang Peihua Niu Wenbo Xu George F.Gao Guizhen Wu | 2020 | China CDC weekly2020，2，4： | 95 |
| 2 | Petawatt and exawatt class lasers worldwide显示文摘In the 2015 review paper‘Petawatt Class Lasers Worldwide’a comprehensive overview of the current status of highpower facilities of>200 TW was presented.This was largely based on facility specifications,with some description of their uses,for instance in fundamental ultra-high-intensity interactions,secondary source generation,and inertial confinement fusion(ICF).With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification(CPA),which made these lasers possible,we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed.We are now in the era of multi-petawatt facilities coming online,with 100 PW lasers being proposed and even under construction.In addition to this there is a pull towards development of industrial and multi-disciplinary applications,which demands much higher repetition rates,delivering high-average powers with higher efficiencies and the use of alternative wavelengths:mid-IR facilities.So apart from a comprehensive update of the current global status,we want to look at what technologies are to be deployed to get to these new regimes,and some of the critical issues facing their development. | Colin N.Danson Constantin Haefner Jake Bromage Thomas Butcher Jean-Christophe FChanteloup Enam A.Chowdhury Almantas Galvanauskas Leonida A.Gizzi Joachim Hein David I.Hillier Nicholas W.Hopps Yoshiaki Kato Efim A.Khazanov Ryosuke Kodama Georg Korn Ruxin Li Yutong Li Jens Limpert Jingui Ma Chang Hee Nam David Neely Dimitrios Papadopoulos Rory R.Penman Liejia Qian Jorge J.Rocca andrey A.Shaykin Craig W.Siders Christopher Spindloe Sándor Szatmári Raoul M.G.M.Trines Jianqiang Zhu Ping Zhu Jonathan D.Zuegel | 2019 | High Power Laser Science and Engineering2019，7，3： | 33 |
| 3 | GDNF-Enhanced Axonal Regeneration and Myelination Following Spinal Cord Injury is Mediated by Primary Effects on Neurons显示文摘我们先前研究表明胶质细胞源性神经营养因子(GDNF)联合施万细胞移植能促进脊髓损伤后轴突再生和髓鞘形成。然而,GDNF介导这一过程的细胞靶点尚不清楚。在此,我们报道了GDNF可增加在体再生轴突的数目和直径,并促进体外背根神经节神经元的轴突向外生长,提示GDNF对神经元有直接作用。在施万细胞-背根神经节神经元共培养下,GDNF显著增加施万细胞生成的髓鞘数目;GDNF处理对孤立培养的施万细胞增殖无作用,但可促进已与神经轴突有突触联系的施万细胞增殖;GDNF可增加孤立施万细胞中分子量为140kDa的神经细胞黏附分子(NCAM)的表达,但对黏附分子L1表达或神经营养因子NGF、NT3及BDNF分泌没有影响。总之,这些结果支持假设:GDNF提高轴突再生和施万细胞髓鞘形成主要是通过GDNF对神经元的直接作用介导的,并且提示GDNF联合施万细胞移植可能是促进脊髓损伤后轴突再生和髓鞘形成的有效策略之一。 | LIQUN ZHANG ZHENGWEN MA GEORGE M.

| 4 | COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented. | Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu | 2021 | China CDC weekly2021，3，21： | 16 |
| 5 | Long Distance Transmission of SARS-CoV-2 from Contaminated Cold Chain Products to Humans——Qingdao City,Shandong Province,China,September 2020显示文摘Summary What is already known about this topic?Though coronavirus disease 2019(COVID-19)has largely been controlled in China,several outbreaks of COVID-19 have occurred from importation of cases or of suspected virus-contaminated products.Though several outbreaks have been traced to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)isolated on the outer packaging of cold chain products,live virus has not been obtained. | Huilai Ma Zhaoguo Wang Xiang Zhao Jun Han Yong Zhang Hong Wang Cao Chen Ji Wang Fachun Jiang Jie Lei Jingdong Song Shaofeng Jiang Shuangli Zhu Huihui Liu Dongyan Wang Yao Meng Naiying Mao Yanhai Wang Zhen Zhu Zhixiao Chen Bingling Wang Qinqin Song Haijun Du Qun Yuan Dong Xia Zhiqiang Xia Peipei Liu Yuchao Wu Zijian Feng Ruqin Gao George F.Gao Wenbo Xu | 2021 | China CDC weekly2021，3，30： | 13 |
| 6 | Electrolytic reduction of mixed solid oxides in molten salts for energy efficient production of the TiNi alloy显示文摘Direct electrochemical reduction of mixed TiO2 and NiO powders to TiNi alloy has been successfully demonstrated in molten CaCl2 at 900℃ by constant voltage electrolysis. The electrolysis en- ergy consumption was as low as 23.4 kWh/kg-TiNi, although the current efficiency was 20.5% in the pre- liminary experiments. During the process, NiO was first reduced to Ni at high speed, accompanied by TiO2 being perovskitized to CaTiO3?x which was gradually reduced to Ni3Ti and TiNi, assisted by the depolarization of the preformed Ni. The cell voltage for preparation of the TiNi alloy was lower than that for Ti. Adjusting the cell voltage not only affected the reduction speed, but also offered a convenient ac- cess to the preparation of the nickel/perovskite composite. | ZHU Yong MA Meng WANG Dihua JIANG Kai HU Xiaohong JIN Xianbo George Z.

| 8 | Paddy System with a Hybrid Rice Enhances Cyanobacteria Nostoc and Increases N2 Fixation显示文摘Biological nitrogen (N) fixation (BNF) plays a significant role in maintaining soil fertility in paddy field ecosystems. Rice variety influences BNF, but how different rice varieties regulate BNF and associated diazotroph communities has not been quantified. Airtight, field-based 15N2-labelling grow th chamber experiments were used to assess the BNF capac 辻 y of different rice varie ties. In addition, both the 16S rRNA and nifH genes were sequenced to assess the influence of different rice varieties on bacterial and diazotrophic communities in paddy soils. After subjecting a rice-soil system to 74 d of continuous airtight, field-based 15N2 labelling in pots in a growth chamber, the amounts of fixed N were 22.3 and 38.9 kg ha^-1 in inbred japonica (W23) and hybrid indica (IIY) rice cultivars plan ted in the rice-soil systems, respectively, and only 1%—2.5% of the fixed N was allocated to the rice plants and weeds. A greater abundance of diazotrophs was found in the surface soil (0-1 cm) under IIY than under W23. Sequencing of the 16S rRNA gene showed significantly greater abundances of the cyanobacterial genera Nostoc, Anabaena, and Cylindrospermum under IIY than under W23. Sequencing of the nifH gene also showed a significantly greater abundance of Nostoc under IIY than under W23. These results indicate that the hybrid rice cultivar (IIY) promoted BNF to a greater extent than the inbred rice cultivar (W23) and that the increase in BNF might have been due to the enhanced heterocystous cyanobacteria Nostoc. | MA Jing BEI Qicheng WANG Xiaojie LIU Gang Georg CADISCH LIN Xingwu ZHU Jianguo SUN Xiaoli XIE Zubin | 2019 | Pedosphere2019，29，3： | 7 |

| 11 | The temporal dynamics of antimicrobial-resistant Salmonella enterica and predominant serovars in China显示文摘Salmonella enterica is one of the most common bacterial pathogens in humans and animals.Systematic studies on the trends and geographical distribution of antimicrobial-resistant Salmonella and dominant serovars have been well studied in European and American countries while not in China.Here,taking the One-Health strategy,we used>35000 Salmonella enterica isolates to explore the temporal and spatial dynamics of dominant serovars in China.We found that Salmonella Typhimurium was the dominant serovar causing human infection in China,which was consistent with Australia but inconsistent with North American and European countries.The proportion of Salmonella serovars Typhimurium,London,Rissen,Corvallis,Meleagridis,Kentucky,and Goldcoast showed an increasing trend during 2006-2019.We randomly selected 1962 isolates for comparative genomics and antimicrobial resistance studies and found that the number of antibiotic resistance genes(ARGs)per isolate increased 1.84 and 2.69 times of human and non-human origins,respectively,spanning 14 years.The proportion of antimicrobial-resistant Salmonella isolates had an increasing trend during 2006-2019,especially beta-lactam,quinolone,tetracycline,and rifampicin resistance.Moreover,we found that higher diversity of sequence types(STs)in S.Typhimurium than in other serovars,ST34 from pig and ST 19 from chicken origin,were mainly associated with isolates causing child and adult gastro-infection,respectively.Our results fill in the data gap on the trends of dominant serovars and antimicrobial resistance of Salmonella enterica in China.These data provide useful information for public health decision-makers prioritizing interventions for foodborne diseases and food safety. | Yanan Wang Yue Liu Na Lyu Zhiyuan Li Sufang Ma Demin Cao Yuanlong Pan Yongfei Hu Hua Huang George F.Gao Xuebin Xu Baoli Zhu | 2023 | National Science Review2023，10，3： | 4 |

| 13 | Identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge, Guyana显示文摘Here,we report the identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge,Guyana.In March 2019,14 employees of Chongqing Bosai Mining Company,China,working in a manganese mining of Guyana,had unexplained fever,and two of them died.We obtained lung and brain tissues as well as the blood samples from the two deceased cases(patient No.1 and 2),and bronchoscopy lavages and cerebrospinal fluid samples from one severe case(patient No.3),respectively.All samples were tested by pathological examination,high-throughput sequencing,and real-time PCR.Pathological detection showed the presence of spore-like structures in the lung tissue of patient No.1,indicating a fungal infection in this patient.Nanopore sequencing identified the existing of H.capsulatum in the lung tissue sample within 13 h.Next-generation sequencing identified specific fragments of H.capsulatum in all of the samples tested(lung,brain and blood serum from the deceased cases,and plasma from the severe case).Real-time PCR assays did not reveal any viral infection related to transmission from bat feces.We conclude that H.capsulatum was the causative pathogen of this disease cluster based on epidemiologic,clinical,pathological and nucleic acid evidence. | Ji Wang Weimin Zhou Hua Ling Xiaoping Dong Yi Zhang Jiandong Li Yong Zhang Jingdong Song William J.Liu Yang Li Ruiqing Zhang Wei Zhen Kun Cai Shuangli Zhu Dongyan Wang Jinbo Xiao Yigang Tong Wenli Liu Lihua Song Wei Wu Yang Liu Xiang Zhao Ruihuan Wang Sheng Ye Jing Wang Roujian Lu Baoying Huang Fei Ye Wenwen Lei Rongbao Gao Qi Shi Cao Chen Jun Han Wenbo Xu George F.Gao Xuejun Ma Guizhen Wu | 2019 | Biosafety and Health2019，1，3： | 3 |

| 19 | Crystal structure of histidine-containing phosphocarrier protein from Thermoanaerobacter tengcongensis MB4 and the implications for thermostability显示文摘Protein thermostability is an inherent characteristic of proteins from thermophilic microorganisms,and therefore enables these organisms to survive at extreme temperatures.Although it is well-known that thermostable proteins are critical for the growth of thermophilic organisms,the structural basis of protein thermostability is not yet fully understood.The histidine-containing phosphocarrier (HPr) protein,a phosphate shuttle protein in the phosphoenolpyruvate-dependent sugar transport system (PTS) of bacterial species,is an ideal model for investigating protein thermostability with respect to its small size and deficiency in disulphide bonds or cofactors.In this study,the HPr protein from Thermoanaerobacter tengcongensis (TtHPr) is cloned and purified.Crystal structure with good quality has been determined at 2.3 resolution,which provides a firm foundation for exploring the thermostable mechanism.However,it shows that the crystal structure is conserved and no clue can be obtained from this single structure.Furthermore,detailed comparison of sequence and structure with the homologs from mesoor thermophilic bacteria shows no obvious rule for thermostability,but the extra salt-bridge existing only in thermophilic bacteria might be a better explanation for thermostability of HPr.Thus,mutations are performed to interrupt the salt-bridge in HPrs in thermophilic bacteria.Using site-directed mutations and the circular dichroism method,thermostability is evaluated,and the mutational variations are shown to have a faster denaturing rate than for wild-type viruses,indicating that mutations cause instability in the HPrs.Understanding the higher-temperature resistance of thermophilic and hyperthermophilic proteins is essential to studies on protein folding and stability,and is critical in engineering efficient enzymes that can work at a high temperature. | FENG ChunYan GAO Feng LIU YiWei WANG GuiHua PENG Hao MA YanHe YAN JingHua GAO George Fu | 2011 | Science China(Life Sciences)2011，54，6： | 2 |
