| 1 | Inhibition of SARS-CoV-2 (previously 2019-nCoV) infection by a highly potent pan-coronavirus fusion inhibitor targeting its spike protein that harbors a high capacity to mediate membrane fusion显示文摘The recent outbreak of coronavirus disease(COVID-19)caused by SARS-CoV-2 infection in Wuhan,China has posed a serious threat to global public health.To develop specific anti-coronavirus therapeutics and prophylactics,the molecular mechanism that underlies viral infection must first be defined.Therefore,we herein established a SARS-CoV-2 spike(S)protein-mediated cell-cell fusion assay and found that SARS-CoV-2 showed a superior plasma membrane fusion capacity compared to that of SARS-CoV.We solved the X-ray crystal structure of six-helical bundle(6-HB)core of the HR1 and HR2 domains in the SARS-CoV-2 S protein S2 subunit revealing that several mutated amino acid residues in the HR1 domain may be associated with enhanced interactions with the HR2 domain.We previously developed a pan-coronavirus fusion inhibitor,EK1,which targeted the HR!domain and could inhibit infection by divergent human coronaviruses tested,including SARS-CoV and MERS-CoV.Here we generated a series of lipopeptides derived from EK1 and found that EK1C4 was the most potent fusion inhibitor against SARS-CoV-2 S protein-mediated membrane fusion and pseudovirus infection with IC50s of 1.3 and 15.8 nM,about 241-and 149-fold more potent than the original EK1 peptide,respectively.EK1C4 was also highly effective against membrane fusion and infection of other human coronavirus pseudoviruses tested,including SARS-CoV and MERS-CoV,as well as SARSr-CoVs,and potently inhibited the replication of 5 live human coronaviruses examined,including SARS-CoV-2.Intranasal application of EK1C4 before or after challenge with HCoV-OC43 protected mice from infection,suggesting that EK1C4 could be used for prevention and treatment of infection by the currently circulating SARS-CoV-2 and other emerging SARSr-CoVs. | Shuai Xia Meiqin Liu Chao Wang Wei Xu Qiaoshuai Lan Siliang Feng Feifei Qi Linlin Bao Lanying Du Shuwen Liu Chuan Qin Fei Sun Zhengli Shi Yun Zhu Shibo Jiang Lu Lu | 2020 | Cell Research2020,30,4: | 81 |
| 2 | AXL is a candidate receptor for SARS-CoV-2 that promotes infection of pulmonary and bronchial epithelial cells显示文摘The current coronavirus disease 2019(COVID-19)pandemic presents a global public health challenge.The viral pathogen responsible,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),binds to the host receptor ACE2 through its spike(S)glycoprotein,which mediates membrane fusion and viral entry.Although the role of ACE2 as a receptor for SARS-CoV-2 is clear,studies have shown that ACE2 expression is extremely low in various human tissues,especially in the respiratory tract.Thus,other host receptors and/or co-receptors that promote the entry of SARS-CoV-2 into cells of the respiratory system may exist.In this study,we found that the tyrosine-protein kinase receptor UFO(AXL)specifically interacts with the N-terminal domain of SARS-CoV-2 S.Using both a SARS-CoV-2 virus pseudotype and authentic SARS-CoV-2,we found that overexpression of AXL in HEK293T cells promotes SARS-CoV-2 entry as efficiently as overexpression of ACE2,while knocking out AXL significantly reduces SARS-CoV-2 infection in HI 299 pulmonary cells and in human primary lung epithelial cells.Soluble human recombinant AXL blocks SARS-CoV-2 infection in cells expressing high levels of AXL.The AXL expression level is well correlated with SARS-CoV-2 S level in bronchoalveolar lavage fluid cells from COVID-19 patients.Taken together,our findings suggest that AXL is a novel candidate receptor for SARS-CoV-2 which may play an important role in promoting viral infection of the human respiratory system and indicate that it is a potential target for future clinical intervention strategies. | Shuai Wang Zongyang Qiu Yingnan Hou Xiya Deng Wei Xu Tingting Zheng Peihan Wu Shaofang Xie Weixiang Bian Chong Zhang Zewei Sun Kunpeng Liu Chao Shan Aifu Lin Shibo Jiang Youhua Xie Qiang Zhou Lu Lu Jing Huang Xu Li | 2021 | Cell Research2021,31,2: | 39 |

| 5 | Overview of Mechanism and Mitigation Measures on Multi-frequency Oscillation Caused by Large-scale Integration of Wind Power显示文摘In recent years,the large-scale integration of re-newable energy sources represented by wind power and the widespread application of power electronic devices in power systems have led to the emergence of multi-frequency oscillation problems covering multiple frequency segments,which seriously threaten system stability and restrict the accommodation of renewable energy.The oscillation problems related to renewable energy integration have become one of the most popular topics in the field of wind power integration and power system stability research.It has received extensive attention from both academia and industries with many promising research results achieved to date.This paper first analyzes several typical multi-frequency oscillation events caused by large-scale wind power integration in domestic and foreign projects,then studies the multi-frequency oscillation problems,including wind turbine’s shafting torsional oscillation,sub/super-synchronous oscillation and high frequency resonance.The state of the art is systematically summarized from the aspects of oscillation mechanism,analysis methods and mitigation measures,and the future research directions are explored. | Yongning Chi Bingjie Tang Jiabing Hu Xinshou Tian Haiyan Tang Yan Li Sujuan Sun Lei Shi Lei Shuai | 2019 | CSEE Journal of Power and Energy Systems2019,5,4: | 23 |

| 7 | Quality analysis of commercial samples of Ziziphi spinosae semen(suanzaoren) by means of chromatographic fingerprinting assisted by principal component analysis显示文摘Due to the scarcity of resources of Ziziphi spinosae semen(ZSS), many inferior goods and even adulterants are generally found in medicine markets. To strengthen the quality control, HPLC fingerprint common pattern established in this paper showed three main bioactive compounds in one chromatogram simultaneously. Principal component analysis based on DAD signals could discriminate adulterants and inferiorities. Principal component analysis indicated that all samples could be mainly regrouped into two main clusters according to the first principal component(PC1, redefined as Vicenin II)and the second principal component(PC2, redefined as zizyphusine). PC1 and PC2 could explain 91.42%of the variance. Content of zizyphusine fluctuated more greatly than that of spinosin, and this result was also confirmed by the HPTLC result. Samples with low content of jujubosides and two common adulterants could not be used equivalently with authenticated ones in clinic, while one reference standard extract could substitute the crude drug in pharmaceutical production. Giving special consideration to the well-known bioactive saponins but with low response by end absorption, a fast and cheap HPTLC methodfor quality control of ZSS was developed and the result obtained was commensurate well with that of HPLC analysis. Samples having similar fingerprints to HPTLC common pattern targeting at saponins could be regarded as authenticated ones. This work provided a faster and cheaper way for quality control of ZSS and laid foundation for establishing a more effective quality control method for ZSS. | Shuai Sun Hailing Liu Shunjun Xu Yuzhen Yan Peishan Xie | 2014 | Journal of Pharmaceutical Analysis2014,4,3: | 17 |

| 9 | Green coal mining technique integrating mining-dressing-gas draining-backfilling-mining显示文摘Aiming to address the following major engineering issues faced by the Pingdingshan No. 12 mine:(1) difficulty in implementing auxiliary lifting because of its depth(i.e., beyond 1000 m);(2) highly gassy main coal seam with low permeability;(3) unstable overlying coal seam without suitable conditions for implementing conventional mining techniques for protective coal seam; and(4) predominant reliance on ‘‘under three' coal resources to ensure production output. This study proposes an integrated, closed-cycle mining-dressing-gas draining-backfilling-mining(MDGBM) technique. The proposed approach involves the mining of protective coal seam, underground dressing of coal and gangue(UDCG), pressure relief and gas drainage before extraction, and backfilling and mining of the protected coal seam. A system for draining gas and mining the protective seam in the rock stratum is designed and implemented based on the geological conditions. This system helps in realizing pressure relief and gas drainage from the protective seam before extraction. Accordingly, another system, which is connected to the existing production system, is established for the UDCG based on the dense medium-shallow trough process. The mixed mining workface is designed to accommodate both solid backfill and conventional fully mechanized coal mining, thereby facilitating coal mining, USCG, and backfilling. The results show that: The mixed mining workface length for the Ji15-31010 protected seam was 220 m with coal production capacity 1.2 million tons per year, while the backfill capacity of gangue was 0.5 million tons per year. The gas pressure decreased from 1.78 to 0.35 MPa, and the total amount of safely mined coal was 1.34 million tons. The process of simultaneously exploiting coal and draining gas was found to be safe, efficient, and green.This process also yielded significant economic benefits. | Zhang Jixiong Zhang Qiang Spearing A.J.S.(Sam) Miao Xiexing Guo Shuai Sun Qiang | 2017 | International Journal of Mining Science and Technology2017,27,1: | 14 |

| 13 | Single-cell transcriptomic atlas of primate cardiopulmonary aging显示文摘Aging is a major risk factor for many diseases,especially in highly prevalent cardiopulmonary comorbidities and infectious diseases including Coronavirus Disease 2019(COVID-19).Resolving cellular and molecular mechanisms associated with aging in higher mammals is therefore urgently needed.Here,we created young and old non-human primate single-nucleus/cell transcriptomic atlases of lung,heart and artery,the top tissues targeted by SARS-CoV-2.Analysis of cell type-specific aging-associated transcriptional changes revealed increased systemic inflammation and compromised virus defense as a hallmark of cardiopulmonary aging.With age,expression of the SARS-CoV-2 receptor angiotensin-converting enzyme 2(ACE2)was increased in the pulmonary alveolar epithelial barrier,cardiomyocytes,and vascular endothelial cells.We found that interleukin 7(IL7)accumulated in aged cardiopulmonary tissues and induced ACE2 expression in human vascular endothelial cells in an NF-κB-dependent manner.Furthermore,treatment with vitamin C blocked IL7-induced ACE2 expression.Altogether,our findings depict the first transcriptomic atlas of the aged primate cardiopulmonary system and provide vital insights into age-linked susceptibility to SARS-CoV-2,suggesting that geroprotective strategies may reduce COVID-19 severity in the elderly. | Shuai Ma Shuhui Sun Jiaming Li Yanling Fan Jing Qu Liang Sun Si Wang Yiyuan Zhang Shanshan Yang Zunpeng Liu Zeming Wu Sheng Zhang Qiaoran Wang Aihua Zheng Shuguang Duo Yang Yu Juan Carlos Izpisua Belmonte Piu Chan Qi Zhou Moshi Song Weiqi Zhang Guang-Hui Liu | 2021 | Cell Research2021,31,4: | 10 |
| 14 | Plant HP1 protein ADCP1 links multivalent H3K9 methylation readout to heterochromatin formation显示文摘Heterochromatin Protein 1 (HP1) recognizes histone H3 lysine 9 methylation (H3K9me) through its conserved chromodomain and maintains heterochromatin from fission yeast to mammals. However, in Arabidopsis, Like Heterochromatin Protein 1 (LHP1) recognizes and colocalizes genome-wide with H3K27me3, and is the functional homolog of Polycomb protein. This raises the question whether genuine HP1 homologs exist in plants. Here, we report on the discovery of ADCP1, a plant-specific triple tandem Agenet protein, as a multivalent H3K9me reader in Arabidopsis, and establish that ADCP1 is essential for heterochromatin formation and transposon silencing through modulating H3K9 and DNA methylation levels. Structural studies revealed the molecular basis underlying H3K9me-specific recognition by tandem Agenet of ADCP1. Similar to human HP1α and fly HP1a, ADCP1 mediates heterochromatin phase separation. Our results demonstrate that despite its distinct domain compositions, ADCP1 convergently evolves as an HP1-equivalent protein in plants to regulate heterochromatin formation. | Shuai Zhao Lingling Cheng Yifei Gao Baichao Zhang Xiangdong Zheng Liang Wang Pilong Li Qianwen Sun Haitao Li | 2019 | Cell Research2019,29,1: | 10 |
| 15 | Science and Prediction of Heavy Rainfall over China:Research Progress since the Reform and Opening-Up of New China显示文摘This paper reviews the major progress on development of the science and prediction of heavy rainfall over China since the beginning of the reform and opening-up of new China(roughly between 1980 and 2019).The progress of research on the physical mechanisms of heavy rainfall over China is summarized from three perspectives:1)the relevant synoptic weather systems,2)heavy rainfall in major sub-regions of China,and 3)heavy rainfall induced by typhoons.The development and application of forecasting techniques for heavy rainfall are summarized in terms of numerical weather prediction techniques and objective forecasting methods.Greatly aided by the rapid progress in meteorological observing technology and substantial improvement in electronic computing,studies of heavy rainfall in China have advanced to investigating the evolution of heavy-rain-producing storms and observational analysis of the cloud microphysical features.A deeper and more systematic understanding of the synoptic systems of importance to the production of heavy rainfall has also been developed.Operational forecast of heavy rainfall in China has changed from subjective weather event forecasts to a combination of both subjective and objective quantitative precipitation forecasts,and is now advancing toward probabilistic quantitative precipitation forecasts with the provision of forecast uncertainty information. | Yali LUO Jisong SUN Ying LI Rudi XIA Yu DU Shuai YANG Yuanchun ZHANG Jing CHEN Kan DAI Xueshun SHEN Haoming CHEN Feifan ZHOU Yimin LIU Shenming FU Mengwen WU Tiangui XIAO Yangruixue CHEN Huiqi LI Mingxin LI | 2020 | Journal of Meteorological Research2020,34,3: | 10 |

| 17 | Simulated Microgravity Conditions and Carbon Ion Irradiation Induce Spermatogenic Cell Apoptosis and Sperm DNA Damage显示文摘Objective To investigate the effect of simulated microgravity and carbon ion irradiation(CIR) on spermatogenic cell apoptosis and sperm DNA damage to the testis of male Swiss Webster mice,and assess the risk associated with space environment.Methods Sperm DNA damage indicated by DNA fragmentation index(DFI) and high DNA stainability(HDS) was measured by sperm chromatin structure assay(SCSA).Apoptosis of spermatogenic cells was detected by annexin V-propidium iodide assay.Bax(the expression levels of p53) and proliferating cell nuclear antigen(PCNA) were measured by immunoblotting;p53 and PCNA were located by immunohistology.Results HDS,DFI,apoptosis index,and the expression levels of p53 and Bax were detected to be significantly higher in the experimental groups(P<0.05) compared with those in the control group;however,the PCNA expression varied to a certain degree.p53-and PCNA-positive expression were detected in each group,mainly in relation to the spermatogonic cells and spermatocytes.Conclusion The findings of the present study demonstrated that simulated microgravity and CIR can induce spermatogenic cell apoptosis and sperm DNA damage.Sperm DNA damage may be one of the underlying mechanisms behind male fertility decline under space environment.These findings may provide a scientific basis for protecting astronauts and space traveler's health and safety. | LI Hong Yan ZHANG Hong MIAO Guo Ying XIE Yi SUN Chao DI Cui Xia LIU Yang LIU Yuan Yuan ZHANG Xin MA Xiao Fei XU Shuai GAN Lu ZHOU Xin | 2013 | Biomedical and Environmental Sciences2013,26,9: | 10 |
| 18 | Allele-aware chromosome-level genome assembly of Artemisia annua reveals the correlation between ADS expansion and artemisinin yield显示文摘Artemisia annua is the major natural source of artemisinin,an anti-malarial medicine commonly used worldwide.Here,we present chromosome-level haploid maps for two A.annua strains with different artemisinin contents to explore the relationships between genomic organization and artemisinin production.High-fidelity sequencing,optical mapping,and chromatin conformation capture sequencing were used to assemble the heterogeneous and repetitive genome and resolve the haplotypes of A.annua.Approximately 5o,ooo genes were annotated for each haplotype genome,and a triplication event that occurred approximately 58.12million years ago was examined for the first time in this species.A total of 3,903,467-5,193,414 variants(SNPs,indels,and structural variants)were identified in the 1.5-Gb genome during pairwise comparison between haplotypes,consistent with the high heterozygosity of this species.Genomic analyses revealed a correlation between artemisinin concents and the copy number of amorpha-4,11-dienes ynthasegenes.This correlation was further confirmed by resequencing of 36A.annua samples with varied artemisinin contents.Circular consensus sequencing of transcripts facilitated the detection of paralog expression.Collectively,our study provides chromosome-level allele-aware genome assemblies for two A.annua strains and new insights into the biosynthesis of artemisinin and its regulation,which will contribute to conquering malaria worldwide. | Baosheng Liao Xiaofeng Shen Li Xiang Shuai Guo Shiyu Chen Ying Meng Yu Liang Dandan Ding Junqi Bai Dong Zhang Tomasz Czechowski Yi Li Hui Yao Tingyu Mai Caroline Howard Chao Sun Haitao Liu Jiushi Liu Jin Pei Jihai Gao Jigang Wang Xiaohui Qiu Zhihai Huang Hongyi Li Ling Yuan Jianhe Wei lan Graham Jiang Xu Boli Zhang Shilin Chen | 2022 | Molecular Plant2022,15,8: | 9 |
| 19 | Contrasting responses of net primary productivity to inter-annual variability and changes of climate among three forest types in northern China显示文摘Aims A lack of explicit information on differential controls on net primary productivity(NPP)across regions and ecosystem types is largely responsible for uncertainties in global trajectories of terrestrial carbon balance with changing environment.The objectives of this study were to determine how NPP of different forest types would respond to inter-annual variability of climate and to examine the responses of NPP to future climate change scenarios across contrasting forest types in northern China.Methods We investigated inter-annual variations of NPP in relation to climate variability across three forest types in northern China,including a boreal forest dominated by Larix gmelinii Rupr.,and two temperate forests dominated by Pinus tabulaeformis Carr.and Quercus wutaishanica Mayr.,respectively,and studied the responses of NPP in these forests to predicted changes in climate for the periods 2011–40,2041–70 and 2070–100 under carbon emission scenarios A2 and B2 of Intergovernmental Panel on Climate Change.We simulated the responses of NPP to predicted changes in future climate as well as inter-annual variability of the present climate with the Biome-BGC version 4.2 based on site-and species-specific parameters.The modeled forest NPP data were validated against values in literature for similar types of forests and compared with inter-annual growth variations reflected by tree-ring width index(RWI)at the study sites.Important Findings Inter-annual variations in modeled NPP during the period 1960–06 were mostly consistent with the temporal patterns in RWI.There were contrasting responses of modeled NPP among the three forest types to inter-annual variability of the present climate as well as to predicted changes in future climate.The modeled NPP was positively related to annual mean air temperature in the L.gmelinii forest(P<0.001),but negatively in the P.tabulaeformis forest(P=0.05)and the Q.wutaishanica forest(P=0.03),while the relationships of modeled NPP with annual precipitation for the three forest types were all positive.Multiple stepwise regression analyses showed that temperature was a more important constraint of NPP than precipitation in the L.gmelinii forest,whereas precipitation appeared to be a prominent factor limiting the growth in P.tabulaeformis and Q.wutaishanica.Model simulations suggest marked,but differential increases in NPP across the three forest types with predicted changes in future climate. | Shuai Ouyang Xiangping Wang Yulian Wu Osbert Jianxin Sun | 2014 | Journal of Plant Ecology2014,7,3: | 9 |
| 20 | Effects of permissive hypocaloric vs standard enteral feeding on gastrointestinal function and outcomes in sepsis显示文摘BACKGROUND Intestinal mucosal barrier injury and gastrointestinal dysfunction are important causes of sepsis.However,few studies have investigated the effects of enteral underfeeding on gastrointestinal function in sepsis.Moreover,no consensus on goal enteral caloric intake has been reached in sepsis.AIM To investigate the effects of different goal caloric requirements of enteral nutrition on the gastrointestinal function and outcomes in the acute phase of sepsis.METHODS Patients were randomly assigned to receive 30%(defined as group A),60%(group B),or 100%(group C)of goal caloric requirements of enteral nutrition in this prospective pilot clinical trial.The acute gastrointestinal injury(AGI)grades,incidence of feeding intolerance(FI),daily caloric intake,nutritional and inflammatory markers,and biomarkers of mucosal barrier function were collected during the first 7 d of enteral feeding.The clinical severity and outcome variables were also recorded.RESULTS A total of 54 septic patients were enrolled.The days to goal calorie of group C(2.55±0.82)were significantly longer than those of group A(3.50±1.51;P=0.046)or B(4.85±1.68;P<0.001).The FI incidence of group C(16.5%)was higher than that of group A(5.0%)or B(8.7%)(P=0.009).No difference in the incidence of FI symptoms was found between groups A and B.The serum levels of barrier function biomarkers of group B were significantly lower than those of group A(P<0.05)on the 7th day of feeding.The prealbumin and IL-6 levels of group A were lower than those of group B(P<0.05)on the 7th day of feeding.No significant differences in the clinical outcome variables or 28-d mortality were found among the three groups.CONCLUSION Early moderate enteral underfeeding(60%of goal requirements)could improve the intestinal barrier function and nutritional and inflammatory status without increasing the incidence of FI symptoms in sepsis.However,further large-scale prospective clinical trials and animal studies are required to test our findings.Moreover,the effects of different protein intake on gastrointestinal function and outcomes should also be investigated in future work. | Jia-Kui Sun Shuai Nie Yong-Ming Chen Jing Zhou Xiang Wang Su-Ming Zhou Xin-Wei Mu | 2021 | World Journal of Gastroenterology2021,27,29: | 9 |
