| 1 | Human monoclonal antibodies block the binding of SARS-CoV-2 spike protein to angiotensin converting enzyme 2 receptor显示文摘According to the World Health Organization(WHO)newly updated situation report on March 18th,2020,the coronavirus disease 2019(COVID-19)pandemic has confirmed 191,127 cases and claimed 7807 deaths worldwide.1 The etiological agent of COVID-19 has been identified as a novel coronavirus,the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),belonging to Sarbecovirus subgenus(genus Betacoronavirus,family Coronaviridae)and showing 79.6 and 96.2%sequence identity in nucleotide to SARS-CoV and a bat coronavirus(BatCoV RaTG13),respectively.2–4 Like SARS-CoV infection,a substantial fraction of COVID-19 patients exhibits severe respiratory symptoms and has to be hospitalized in intensive care unit.5–8 Although the mortality rate of COVID-19 is significantly lower than that of SARS-CoV infection,SARS-CoV-2 shows much higher human-to-human transmission rate,rapidly leading to a global pandemic declared by WHO on March 11th,2020. | Xiangyu Chen Ren Li Zhiwei Pan Chunfang Qian Yang Yang Renrong You Jing Zhao Pinghuang Liu Leiqiong Gao Zhirong Li Qizhao Huang Lifan Xu Jianfang Tang Qin Tian Wei Yao Li Hu Xiaofeng Yan Xinyuan Zhou Yuzhang Wu Kai Deng Zheng Zhang Zhaohui Qian Yaokai Chen Lilin Ye | 2020 | Cellular & Molecular Immunology2020，17，6： | 17 |
| 2 | The rare two-dimensional materials with Dirac cones显示文摘Inspired by the great development of graphene, more and more research has been conducted to seek new two-dimensional(2D) materials with Dirac cones. Although 2D Dirac materials possess many novel properties and physics, they are rare compared with the numerous 2D materials. To provide explanation for the rarity of 2D Dirac materials as well as clues in searching for new Dirac systems, here we review the recent theoretical aspects of various 2D Dirac materials, including graphene, silicene, germanene,graphynes, several boron and carbon sheets, transition-metal oxides(VO2)n/(TiO2)m and(CrO2)n/(TiO2)m, organic and organometallic crystals, so-MoS2, and artiicial latices(electron gases and ultracold atoms). heir structural and electronic properties are summarized. We also investigate how Dirac points emerge, move, and merge in these systems. he von Neumann–Wigner theorem is used to explain the scarcity of Dirac cones in 2D systems, which leads to rigorous requirements on the symmetry,parameters, Fermi level, and band overlap of materials to achieve Dirac cones. Connections between existence of Dirac cones and the structural features are also discussed. | Jinying Wang Shibin Deng Zhongfan Liu Zhirong Liu | 2015 | National Science Review2015，2，1： | 10 |
| 3 | Strain Effects in Graphene and Graphene Nanoribbons:The Underlying Mechanism显示文摘A tight-binding analytic framework is combined with first-principles calculations to reveal the mechanism underlying the strain effects on electronic structures of graphene and graphene nanoribbons(GNRs).It provides a unified and precise formulation of the strain effects under various circumstances-including the shift of the Fermi(Dirac)points,the change in band gap of armchair GNRs with uniaxial strain in a zigzag pattern and its insensitivity to shear strain,and the variation of the k-range of edge states in zigzag GNRs under uniaxial and shear strains which determine the gap behavior via the spin polarization interaction. | Yang Li Xiaowei Jiang Zhongfan Liu Zhirong Liu | 2010 | Nano Research2010，3，8： | 8 |

| 5 | Multifunctional polymeric micelle-based chemo-immunotherapy with immune checkpoint blockade for efficient treatment of orthotopic and metastatic breast cancer显示文摘Immunotherapy has become a highly promising paradigm for cancer treatment. Herein, a chemo-immunotherapy was developed by encapsulating chemotherapeutic drug doxorubicin(DOX) and Toll-like receptor 7 agonist imiquimod(IMQ) in low molecular weight heparin(LMWH)-D-α-tocopheryl succinate(TOS) micelles(LT). In this process, LMWH and TOS were conjugated by ester bond and they were not only served as the hydrophilic and hydrophobic segments of the carrier, but also exhibited strong anti-metastasis effect. The direct killing of tumor cells mediated by DOX-loaded micelles(LT-DOX)generated tumor-associated antigens, initiating tumor-specific immune responses in combination with IMQ-loaded micelles(LT-IMQ). Furthermore, the blockade of immune checkpoint with programmed cell death ligand 1(PD-L1) antibody further elevated the immune responses by up-regulating the maturation of DCs as well as the ratios of CD8+ CTLs/Treg and CD4+ Teff/Treg. Therefore, such a multifunctional strategy exhibited great potential for inhibiting the growth of orthotopic and metastatic breast cancer. | Jiaojie Wei Yang Long Rong Guo Xinlei Liu Xian Tang Jingdong Rao Sheng Yin Zhirong Zhang Man Li Qin He | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 8 |
| 6 | Rhizosphere and bulk soil enzyme activities in a Nothotsuga longibracteata forest in the Tianbaoyan National Nature Reserve,Fujian Province,China显示文摘The rhizosphere, distinct from bulk soil, is defined as the volume of soil around living roots and influenced by root activities. We investigated protease,invertase, cellulase, urease, and acid phosphatase activities in rhizosphere and bulk soils of six Nothotsuga longibracteata forest communities within Tianbaoyan National Nature Reserve, including N. longibracteata + either Phyllostachys pubescens, Schima superba, Rhododendron simiarum, Cunninghamia lanceolata, or Cyclobalanopsis glauca, and N. longibracteata pure forest. Rhizosphere soils possessed higher protease, invertase, cellulase, urease,and acid phosphatase activities than bulk soils. The highest invertase, urease, and acid phosphatase activities were observed in rhizosphere samples of N. longibracteata+ S.superba. Protease was highest in the N. longibracteata + R. simiarum rhizosphere, while cellulase was highest in the pure N. longibracteata forest rhizosphere.All samples exhibited obvious rhizosphere effects on enzyme activities with a significant linear correlation between acid phosphatase and cellulase activities(p \ 0.05) in rhizosphere soils and between protease and acid phosphatase activities(p \ 0.05) in bulk soils. A principal component analysis, correlating 13 soil chemical properties indices relevant to enzyme activities, showed that protease, invertase, acid phosphatase, total N, and cellulase were the most important variables impacting rhizosphere soil quality. | Shihong Xiao Huiming You Weibin You Jinshan Liu Changtang Cai Jianqin Wu Zhirong Ji Shihua Zhan Zhesen Hu Zhongrui Zhang Dongjin He | 2017 | Journal of Forestry Research2017，28，3： | 7 |
| 7 | Mapping the Nuclear Fertility Restorer Gene in Rice with Simple Sequence Length Polymorphism (SSLP)显示文摘Bulked segregant analysis (BSA) of a F2 population derived from D62A/Ruby B was used to map the nuclear fertility restorer gene for wild abortive (WA) cytoplasmic male sterility. Three hundred and ninety-seven microsatellite primer pairs which distributed on 12 chromosomes were screened for polymorphisms between the parents and between two bulks representing fertile and sterile plants. One microsatellite marker RM182 located on chromosome 7 produced polymorphic products. The nuclear fertility restorer gene for WA cytoplasmic male sterility was mapped on chromosome 7, 7.4cM from RM182. | 朱建清 Zhang Hanyao Liu Zhu Liao Jinhua LI Shujin Ye Xiaoying Wang Lihua Zhao Jian Yang Zhirong | 2004 | High Technology Letters2004，10，4： | 5 |
| 8 | The histone methyltransferase EZH2 primes the early differentiation of follicular helper T cells during acute viral infection显示文摘Epigenetic modifications to histones dictate the differentiation of naïve CD4^(+) T cells into different subsets of effector T helper(TH)cells.The histone methyltransferase enhancer of zeste homolog 2(EZH2)has been implicated in the mechanism regulating the differentiation of TH1,TH2 and regulatory T(Treg)cells.However,whether and how EZH2 regulates follicular helper T(TFH)cell differentiation remain unknown.Using a mouse model of acute lymphocytic choriomeningitis virus(LCMV)infection,we observed abundant EZH2 expression and associated H3K27me3 modifications preferentially in the early committed virus-specific TFH cells compared to those in TH1 cells.Ablation of EZH2 in LCMV-specific CD4^(+) T cells leads to a selective impairment of early TFH cell fate commitment,but not late TFH differentiation or memory TFH maintenance.Mechanistically,EZH2 specifically stabilizes the chromatin accessibility of a cluster of genes that are important for TFH fate commitment,particularly B cell lymphoma 6(Bcl6),and thus directs TFH cell commitment.Therefore,we identified the chromatin-modifying enzyme EZH2 as a novel regulator of early TFH differentiation during acute viral infection. | Xiangyu Chen Guoshuai Cao Jialin Wu Xinxin Wang Zhiwei Pan Jianbao Gao Qin Tian Lifan Xu Zhirong Li Yaxing Hao Qizhao Huang Pengcheng Wang Minglu Xiao Luoyingzi Xie Shupei Tang Zhenyu Liu Li Hu Jianfang Tang Ran He Li Wang Xinyuan Zhou Yuzhang Wu Mengjie Chen Beicheng Sun Bo Zhu Jun Huang Lilin Ye | 2020 | Cellular & Molecular Immunology2020，17，3： | 4 |
| 9 | Influences of multi factors on thermal runaway induced by overcharging of lithium-ion battery显示文摘Thermal runaway caused by overcharging results in catastrophic disasters. The influences of charging rate, ambient temperature and aging on thermal runaway caused by overcharging are studied qualitatively and quantitatively in this manuscript. The results of overcharging tests indicate that high charging rate and ambient temperature increase thermal runaway risk. Aging in 40 ℃ decreases thermal runaway risk. The risk increase of battery with high overcharging rate and in high ambient temperature is due to fast lithium plating reaction and accelerated SEI decomposition, respectively. The risk decrease of aged battery is due to the occurrence of SEI before overcharging tests. SEI suppresses the side reactions between lithium plating and electrolyte. The results of orthogonal tests indicate that the rank of effect is: discharging rate > ambient temperature > aging. The heat generation is calculated based on the results of overcharging tests. The calculation results indicate that heat generated by side reactions contributes more to the total heat generation. Although thermal runaway does not occur during overcharging with low current, the heat dissipation of the lithium-ion battery is the most and deserves focus. The results are important to the design of battery management system and thermal management system to prevent thermal runaway induced by overcharging in total lifespan of battery. | Jialong Liu Zhirong Wang Jinlong Bai | 2022 | Journal of Energy Chemistry2022，31，7： | 4 |
| 10 | Influence of Metallic Modification on Ethylbenzene Dealkylation over ZSM-5 Zeolites显示文摘A series of metal-modified HZSM-5 catalysts were prepared by impregnation and were used for ethylbenzene dealkylation of the mixed C8 aromatics(ethylbenzene,m-xylene and o-xylene).The effects of different supported metals(Pt,Pd,Ni,Mo)on catalytic performance,including reaction conditions,were investigated.The physicochemical properties of catalysts were characterized by means of XRD,BET,TEM and NH_(3)-TPD.Experimental results showed that metallic modification obviously increased the ethylbenzene conversion and reduced the coke deposition,greatly improving the catalyst stability.The distinction of ethylbenzene conversion depended on the interaction between hydrogenation reactivity and acidic cracking of bifunctional metal-modified zeolites.Compared with Pt and Ni,Pd and Mo were easier to disperse into HZSM-5 micropores during loading metals.The acidic density of different metal-modified HZSM-5 declined in the following order:HZSM-5>Pt/HZSM-5>Pd/HZSM-5>Ni/HZSM-5>Mo/HZSM-5.The activity of ethylene hydrogenation decreased with Pt/HZSM-5>Pd/HZSM-5>Ni/HZSM-5>Mo/HZSM-5.In comparison,Pd/HZSM-5 showed the best catalytic performance with both high activity and high selectivity,with less cracking loss of m-xylene and o-xylene.Moreover,the following reaction conditions were found to be preferable for ethylbenzene dealkylation over Pd/HZSM-5:340℃,1.5 MPa H2,WHSV 4 h^(−1),H_(2)/C84 mol/mol. | Chao Hu Junhui Li Wenzhi Jia Min Liu Zhixian Hao Zhirong Zhu | 2015 | Chinese Journal of Chemistry2015，33，2： | 3 |
| 11 | Phosphonate-Decorated Covalent Organic Frameworks for Actinide Extraction: A Breakthrough Under Highly Acidic Conditions显示文摘Although solid-phase extraction is a useful approach for metal ion separation from aqueous solutions,existing sorbents suffer from low extraction effici-encies and/or instability when in contact with strong acidic media.We report here the first study on rational design and fabrication of phosphonate-decorated covalent organic frameworks,COF-IHEP1 and COF-IHEP2,for efficient and selective extraction of of uranium(VI)[U(VI)]and plutonium(IV)[Pu(IV)]from highly acidic solutions. | Jipan Yu Liyong Yuan Shuai Wang Jianhui Lan Lirong Zheng Chao Xu Jing Chen Lin Wang Zhiwei Huang Wuqing Tao Zhirong Liu Zhifang Chai John K.Gibson Weiqun Shi | 2019 | CCS Chemistry2019，1，3： | 3 |

| 13 | Advances in photosensitizer-related design for photodynamic therapy显示文摘Photodynamic therapy(PDT)is highly effective in treating tumors located near body surface,offering strong tumor suppression and low damage to normal tissue nearby.PDT is also effective for treating a number of other conditions.PDT not only provide a precise and selective method for the treatment of various diseases by itself,it can also be used in combination with other traditional therapies.Because PDT uses light as the unique targeting mechanism,it has simpler and more direct targeting capability than traditional therapies.The core material of a PDT system is the photosensitizer which converts light energy to therapeutic factors/substances.Different photosensitizers have their distinct characteristics,leading to different advantages and disadvantages.These could be enhanced or compensated by using proper PDT system.Therefore,the selected type of photosensitizer would heavily influence the overall design of a PDT system.In this article,we evaluated major types of inorganic and organic PDT photosensitizers,and discussed future research directions in the field. | Zhaojie Zhou Ling Zhang Zhirong Zhang Zhenmi Liu | 2021 | Asian Journal of Pharmaceutical Sciences2021，16，6： | 2 |
| 14 | The dichotomous and incomplete adaptive immunity in COVID-19 patients with different disease severity显示文摘The adaptive immunity that protects patients from coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),is not well characterized.In particular,the asymptomatic patients have been found to induce weak and transient SARS-CoV-2 antibody responses,but the underlying mechanisms remain unknown;meanwhile,the protective immunity that guide the recovery of these asymptomatic patients is elusive.Here,we characterized SARS-CoV-2-specific B-cell and T-cell responses in 10 asymptomatic patients and 64 patients with other disease severity(mild,n=10,moderate,n=32,severe,n=12)and found that asymptomatic or mild symptomatic patients failed to mount virus-specific germinal center(GC)B cell responses that result in robust and prolonged humoral immunity,assessed by GC response indicators including follicular helper T(TFH)cell and memory B cell responses as well as serum CXCL13 levels.Alternatively,these patients mounted potent virus-specific TH1 and CD8+T cell responses.In sharp contrast,patients of moderate or severe disease induced vigorous virus-specific GC B cell responses and associated TFH responses;however,the virus-specific TH1 and CD8+T cells were minimally induced in these patients.These results,therefore,uncovered the protective immunity in asymptomatic patients and also revealed the strikingly dichotomous and incomplete humoral and cellular immune responses in COVID-19 patients with different disease severity,providing important insights into rational design of effective COVID-19 vaccines. | Leiqiong Gao Jing Zhou Sen Yang Lisha Wang Xiangyu Chen Yang Yang Ren Li Zhiwei Pan Jing Zhao Zhirong Li Qizhao Huang Jianfang Tang Li Hu Pinghuang Liu Guozhong Zhang Yaokai Chen Lilin Ye | 2021 | Signal Transduction and Targeted Therapy2021，6，4： | 2 |

| 16 | Asymptomatic patients and asymptomatic phases of Coronavirus Disease 2019(COVID-19):a population-based surveillance study显示文摘In this population-based study,we identified 307 confirmed COVID-19 cases from massive surveillance,including 129551 individuals screened at fever clinics or returning from Hubei and 3710 close contacts of confirmed COVID-19 patients.Among them,17 patients were asymptomatic at initial clinical assessment.These asymptomatic patients on admission accounted for a small proportion of all patients(5.54%)with relatively weak transmissibility,and the detection rate was 0.35 per 100 close contacts.Moreover,the dynamics of symptoms of the 307 patients showed that the interval from symptom remission to the final negativity of viral nucleic acid was 5.0 days(interquartile range 2.0 to 11.0 days),with 14 patients(4.56%)having re-detectable viral RNA after discharge.Overall;our findings suggested asymptomatic carriers and presymptomatic patients only accounted for a small proportion of COVID-19 patients.Also,the asymptomatic phase during recovery from COVID-19 implied that negativity in viral RNA is necessary as a de-isolation criterion and follow-up is recommended. | Xueying Zheng Sihui Luo Yong Sun Mingfeng Han Jian Liu Liangye Sun Liangming Zhang Ping Ling Yu Ding Tengchuan Jin Zhirong Liu Jianping Weng | 2020 | National Science Review2020，7，10： | 2 |
| 17 | Biodegradation Kinetics for Pre-treatment of Klebsiella pneumoniae Waste with Autothermal Thermophilic Aerobic Digestion显示文摘Biodegradation parameters and kinetic characteristics for pre-treating waste strains of Klebsiella pneu-moniae were studied in laboratory scale with an insulated reactor by an innovative technique,autothermal thermo-philic aerobic digestion(ATAD) . Based on an Arrhenius-type equation,an empirical model was developed to corre-late the removal of total suspended solid(TSS) with the initial TSS concentration,influent reaction temperature,aeration rate and stirring rate. The reaction temperatures of the ATAD system could be raised from the ambient temperatures of 25 °C to a maximum temperature of 65 °C. The exponentials for the initial TSS concentration,aeration rate and stirring rate were 1.579,-0.8175 and-0.6549,respectively,and the apparent activation energy was 6.8774 kJ·mol-1. The correlation coefficient for the pre-exponential factor was 0.9223. The TSS removal effi-ciency predicted by the model was validated with an actual test,showing a maximum relative deviation of 10.79%. The new model has a good practicability. | LIU Jingming SUN Dongdong LIU Hui NIE Yingbin ZHU Zhirong | 2010 | Chinese Journal of Chemical Engineering2010，18，6： | 2 |
| 18 | Bioinformatical study on the proteomics and evolution of SARS-CoV显示文摘A novel coronavirus has been identified as the causative agent of the severe acute respiratory syndrome(SARS). For all the SARS-CoV associated proteins derivatedfrom the SARS-CoV genome, the physiochemical propertiessuch as the molecular weight, isoelectric point and extinction coefficient of each protein were calculated. Thetransmembrane segments and subcellular localization(SubLocation) prediction and conserved protein motifssearch against database were employed to analyze thefunction of SARS-CoV proteins. Also, the homology protein sequence alignment and evolutionary distance matrixcalculation between SARS-CoV associated proteins and the corresponding proteins of other coronaviruses wereemployed to identify the classification and phylogeneticrelationship between SARS-CoV and other coronaviruses.The results showed that SARS-CoV is a novel coronavirus which is different from any of the three previously knowngroups of coronviruses, but it is closer to BoCoV and MHV than to other coronaviruses. This study is in aid ofexperimental determination of SARS-CoV proteomics andthe development of antiviral vaccine. | LIU Shuqun*, GUO Tao*, JI Xinglai & SUN Zhirong Institute of Bioinformatics, Department of Biological Sciences andBiotechnology, Tsinghua University, Beijing 100084, China * The two authors contributed equally to this work.

| 20 | Recent Progress in Nanoscale Covalent Organic Frameworks for Cancer Diagnosis and Therapy显示文摘Covalent organic frameworks(COFs)as a type of porous and crystalline covalent organic polymer are built up from covalently linked and periodically arranged organic molecules.Their precise assembly,welldefined coordination network,and tunable porosity endow COFs with diverse characteristics such as low density,high crystallinity,porous structure,and large specific-surface area,as well as versatile functions and active sites that can be tuned at molecular and atomic level.These unique properties make them excellent candidate materials for biomedical applications,such as drug delivery,diagnostic imaging,and disease therapy.To realize these functions,the components,dimensions,and guest molecule loading into COFs have a great influence on their performance in various applications.In this review,we first introduce the influence of dimensions,building blocks,and synthetic conditions on the chemical stability,pore structure,and chemical interaction with guest molecules of COFs.Next,the applications of COFs in cancer diagnosis and therapy are summarized.Finally,some challenges for COFs in cancer therapy are noted and the problems to be solved in the future are proposed. | Shuncheng Yao Zhirong Liu Linlin Li | 2021 | Nano-Micro Letters2021，13，11： | 1 |
