2Humoral immune response to circulating SARS-CoV-2 variants elicited by inactivated and RBD-subunit vaccines显示文摘SARS-CoV-2 variants could induce immune escape by mutations on the receptor-binding domain(RBD)and N-terminal domain(NTD).Here we report the humoral immune response to circulating SARS-CoV-2 variants,such as 501Y.V2(B.1.351),of the plasma and neutralizing antibodies(NAbs)elicited by CoronaVac(inactivated vaccine),ZF2001(RBD-subunit vaccine)and natural infection.Among 86 potent NAbs identified by high-throughput single-cell VDJ sequencing of peripheral blood mononuclear cells from vaccinees and convalescents,near half anti-RBD NAbs showed major neutralization reductions against the K417N/E484K/N501Y mutation combination,with E484K being the dominant cause.VH3-53/VH3-66 recurrent antibodies respond differently to RBD variants,and K417N compromises the majority of neutralizing activity through reduced polar contacts with complementarity determining regions.In contrast,the 242–244 deletion(242–244Δ)would abolish most neutralization activity of anti-NTD NAbs by interrupting the conformation of NTD antigenic supersite,indicating a much less diversity of anti-NTD NAbs than anti-RBD NAbs.Plasma of convalescents and CoronaVac vaccinees displayed comparable neutralization reductions against pseudo-and authentic 501Y.V2 variants,mainly caused by E484K/N501Y and 242–244Δ,with the effects being additive.Importantly,RBD-subunit vaccinees exhibit markedly higher tolerance to 501Y.V2 than convalescents,since the elicited anti-RBD NAbs display a high diversity and are unaffected by NTD mutations.Moreover,an extended gap between the third and second doses of ZF2001 leads to better neutralizing activity and tolerance to 501Y.V2 than the standard three-dose administration.Together,these results suggest that the deployment of RBD-vaccines,through a third-dose boost,may be ideal for combating SARS-CoV-2 variants when necessary,especially for those carrying mutations that disrupt the NTD supersite.Yunlong Cao Ayijiang Yisimayi Yali Bai Weijin Huang Xiaofeng Li Zhiying Zhang Tianjiao Yuan Ran An Jing Wang Tianhe Xiao Shuo Du Wenping Ma Liyang Song Yongzheng Li Xiang Li Weiliang Song Jiajing Wu Shuo Liu Xuemei Li Yonghong Zhang Bin Su Xianghua Guo Yangyang Wei Chuanping Gao Nana Zhang Yifei Zhang Yang Dou Xiaoyu Xu Rui Shi Bai Lu Ronghua Jin Yingmin Ma Chengfeng Qin Youchun Wang Yingmei Feng Junyu Xiao Xiaoliang Sunney Xie 2021Cell Research2021,31,7:12
3MVS-Pheno:A Portable and Low-Cost Phenotyping Platform for Maize Shoots Using Multiview Stereo 3D Reconstruction显示文摘Plant phenotyping technologies play important roles in plant research and agriculture.Detailed phenotypes of individual plants can guide the optimization of shoot architecture for plant breeding and are useful to analyze the morphological differences in response to environments for crop cultivation.Accordingly,high-throughput phenotyping technologies for individual plants grown in field conditions are urgently needed,and MVS-Pheno,a portable and low-cost phenotyping platform for individual plants,was developed.The platform is composed of four major components:a semiautomatic multiview stereo(MVS)image acquisition device,a data acquisition console,data processing and phenotype extraction software for maize shoots,and a data management system.The platform’s device is detachable and adjustable according to the size of the target shoot.Image sequences for each maize shoot can be captured within 60-120 seconds,yielding 3D point clouds of shoots are reconstructed using MVS-based commercial software,and the phenotypic traits at the organ and individual plant levels are then extracted by the software.The correlation coefficient(R^(2))between the extracted and manually measured plant height,leaf width,and leaf area values are 0.99,0.87,and 0.93,respectively.A data management system has also been developed to store and manage the acquired raw data,reconstructed point clouds,agronomic information,and resulting phenotypic traits.The platform offers an optional solution for high-throughput phenotyping of field-grown plants,which is especially useful for large populations or experiments across many different ecological regions.Sheng Wu Weiliang Wen Yongjian Wang Jiangchuan Fan Chuanyu Wang Wenbo Gou Xinyu Guo 2020Plant Phenomics2020,2,1:11
4Humoral immunogenicity and reactogenicity of CoronaVac or ZF2001 booster after two doses of inactivated vaccine显示文摘Dear Editor,COVID-19 vaccination campaigns are being conducted in countries worldwide,and 47.4% of the world population has received at least one dose of a COVID-19 vaccine.1 Although vaccination has shaped COVID-19 epidemic curves,waning antibody levels and relatively short-duration protection provided by current COVID-19 vaccines have been observed,especially against SARS-CoV-2 variants of concern(VOCs)and among older individuals.Yunlong Cao Xiaohua Hao Xi Wang Qianhui Wu Rui Song Dong Zhao Weiliang Song Yao Wang Ayijiang Yisimayi Wei Wang Juan Du Hongjie Yu Xiaoliang Sunney Xie Ronghua Jin 2022Cell Research2022,32,1:8
5Experimental study on interaction between membrane structures and wind environment显示文摘The interaction between membrane structures and their environment can be either static or dynamic. Static interaction refers to interaction with static air, while dynamic interaction refers to wind and its effects. They can be evaluated by two parameters, added mass and radiation /aerodynamic damping, which are experimentally investigated in this study. The study includes the effects of both the static and dynamic interaction on structural dynamic characteristics, and the relationship between the interaction parameters and the covered area of a membrane structure for the static interaction and the relationship between the interaction parameters and wind direction and speed for the dynamic interaction. Experimental data show that the dynamic interaction is strongly correlated with the structural modes, i.e., the interaction of the symmetric modes is much larger than the anti-symmetric modes; and the influence of the dynamic interaction is significant in wind-induced response analysis and cannot be ignored. In addition, it is concluded that the structural natural frequency is remarkably decreased by this interaction, and the frequency band is significantly broadened.Yang Qingshan Wu Yue Zhu Weiliang 2010Earthquake Engineering and Engineering Vibration2010,9,4:6

7User Association in Heterogeneous Network with Dual Connectivity and Constrained Backhaul显示文摘A novel user association model for heterogeneous network(Het Net) with dual connectivity(DC) and constrained backhaul is proposed in this paper, where not only the best combination of serving macro cell and small cell for each user to associate is selected but also the optimal traffi c split between the macro cell and small cell is determined to enhance both radio resource effi ciency and backhaul capacity utilization. To solve this optimization problem, an intuitive algorithm based on iteratively solving two sub-problems is proposed. One sub-problem is a binary integer programming problem and a corresponding greedy algorithm is proposed, while the other sub-problem is a simple linear programming problem and can be easily solved. Numerical results show that the proposed model and algorithm can achieve better radio resource effi ciency and backhaul capacity utilization compared with user association in Het Net without DC, which validate the capacity enhancement potentials of radio resource coordination in Het Net with DC.WU Zhouyun XIE Weiliang YANG Fengyi BI Qi 2016China Communications2016,13,2:5
8Targeting the PI3K/Akt/mTOR signaling pathway by pterostilbene attenuates mantle cell lymphoma progression显示文摘Dandan Yu Yong Zhang Gege Chen Yongsheng Xie Zhijian Xu Shuaikang Chang Liangning Hu Bo Li Wenxuan Bu Yingcong Wang Wenqin Xiao Xi Sun Gaomei Chang Lu Gao Sujing Qiang Xiaosong Wu Weiliang Zhu Jumei Shi 2018Acta Biochimica et Biophysica Sinica2018,50,8:4
9DCZ0801,a novel compound,induces cell apoptosis and cell cycle arrest via MAPK pathway in multiple myeloma显示文摘Multiple myeloma(MM)is a refractory malignant hematological malignancy,and many therapeutic strategies have been developed to cure patients with MM.DCZ0801 is a compound that consists of oxophenamide and pterostilbene.The role of these compounds in hematological cancers such as MM has yet to be studied.In this study,we explored the potential mechanism of DCZ0801 action,its anti-tumor activity both in vitro and in vivo on MM.This study was carried out via cell cycle proliferation assay,apoptotic analysis,western blot analysis,and examination of xenotransplantation model of tumors.The in vitro studies revealed that DCZ0801 could inhibit cell proliferation and induce apoptosis by regulating both caspase-dependent and mitogen-activated protein kinase signaling pathways,inducing S-phase arrest of the cell cycle related to downregulation of CDK2,cyclin-A2,and CDC25A protein expression.The in vivo studies showed that DCZ0801 could significantly reduce the size of the tumors in nude mice.Our results demonstrated that DCZ0801 may emerge as the new therapeutic option for the patient with MM.Ting Zhang Bo Li Qilin Feng Zhijian Xu Cheng Huang Huiqun Wu Zhangbo Chen Liangning Hu Lu Gao Peng Liu Guang Yang Hui Zhang Kang Lu Tingye Li Yi Tao Xiaosong Wu Jumei Shi Weiliang Zhu 2019Acta Biochimica et Biophysica Sinica2019,51,5:3
10SARS-CoV-2 Omicron RBD shows weaker binding affinity than the currently dominant Delta variant to human ACE2显示文摘Dear Editor,SARS-coronavirus-2(SARS-CoV-2)Omicron variant(B.1.1.529)is of great concern to the world due to its multiple mutations that may have an impact on transmissibility and immune evasion.1 Compared to the wild type(WT),Omicron carries as many as 30 single point mutations,3 deletion mutation and one insertion mutation on its spike protein.Strikingly,there are 15 mutations observed in the Omicron receptor-binding domain(RBD),10 of which are in the receptor-binding motif(RBM)that human angiotensin-converting enzyme 2(ACE2)and most monoclonal antibodies(mAbs)interact directly with.As a comparison,the currently dominant variant Delta(B.1.617.2)has only 2 mutations(L452R and T478K)in its RBM and additional K417N and E484K mutations sometimes.Therefore,Omicron variant may significantly impact the binding affinity to ACE2 and effectiveness of currently available mAbs.Consequently,Omicron mutant has aroused wide concern,many countries have taken measures on entry restrictions to prevent its rapid spread.However,the transmissibility and immune evasion risk of Omicron have not been properly evaluated.Leyun Wu Liping Zhou Mengxia Mo Tingting Liu Chengkun Wu Chunye Gong Kai Lu Likun Gong Weiliang Zhu Zhijian Xu 2022Signal Transduction and Targeted Therapy2022,7,2:2

12Bacillus velezensis JK-XZ8 prevents and controls crown gall disease on Prunus subhirtella by colonizing and inducing resistance显示文摘Crown gall of Prunus subhirtella Miq., flowering cherry, is a soil-borne bacterial disease caused by Agrobacterium tumefaciens Smith & Townsend and has caused serious damage to the species in recent years in China. In this study, the colonization of sapling roots, the biocontrol efficacy, the expression of defense-related genes and the enzyme activity in roots of P. subhirtella inoculated with the Bacillus velezensis JK-XZ8 against A. tumefaciens were determined under greenhouse conditions. The results showed that the JK-XZ8 strain colonized in the rhizosphere and root surfaces of the saplings. Sole application of the strain increased activities of polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL) without affecting superoxide dismutase (SOD). SOD and PPO activities increased in the prevention group, and the activity of PAL increased in both the prevention and cure groups. The expression of the defense-related genes PAL and PR-1 of salicylic acid pathway in roots increased in both the prevention and cure groups. Simultaneously on day 3, the expression of both COI and MYC2 genes of the jasmonic acid pathway significantly increased in the two groups. The incidence of crown gall in the prevention and the cure groups were 48.1% and 66.7%, respectively, significantly lower compared to the pathogens alone (87.5%). This study showed that the application of the JK-XZ8 strain reduced the incidence of crown gall in P. subhirtella saplings in the two groups, and the prevention group had better control efficacy. In addition, the JK-XZ8 strain protects against crown gall by developing induced systemic resistance and systemic acquired resistance in the roots of the cherry saplings.Xitang Zhang Weiliang Kong Xiaoqin Wu Jianren Ye 2022Journal of Forestry Research2022,33,3:1

16Fuzzy stochastic generalized reliability studies on embankment systems based on first-order approximation theorem显示文摘In order to address the complex uncertainties caused by interfacing between the fuzziness and randomness of the safety problem for embankment engineering projects, and to evaluate the safety of embankment engineering projects more scientifically and reasonably, this study presents the fuzzy logic modeling of the stochastic finite element method (SFEM) based on the harmonious finite element (HFE) technique using a first-order approximation theorem. Fuzzy mathematical models of safety repertories were introduced into the SFEM to analyze the stability of embankments and foundations in order to describe the fuzzy failure procedure for the random safety performance function. The fuzzy models were developed with membership functions with half depressed gamma distribution, half depressed normal distribution, and half depressed echelon distribution. The fuzzy stochastic mathematical algorithm was used to comprehensively study the local failure mechanism of the main embankment section near Jingnan in the Yangtze River in terms of numerical analysis for the probability integration of reliability on the random field affected by three fuzzy factors. The result shows that the middle region of the embankment is the principal zone of concentrated failure due to local fractures. There is also some local shear failure on the embankment crust. This study provides a referential method for solving complex multi-uncertainty problems in engineering safety analysis.Wang Yajun Zhang Wohua Jin Weiliang Wu Changyu Ren Dachun 2008Water Science and Engineering2008,1,4:1
17DCZ3301, a novel aryl-guanidino inhibitor, induces cell apoptosis and cell cycle arrest via suppressing the PI3K/AKT pathway in T-cell leukemia/lymphoma显示文摘Wenqin Xiao Bo Li Xi Sun Dandan Yu Yongsheng Xie Huiqun Wu Shuaikang Chang Yunfei Zhou Houcai Wang Xiucai Lan Zhijian Xu Jumei Shi Weiliang Zhu 2018Acta Biochimica et Biophysica Sinica2018,50,7:1
18Anti-DLBCL efficacy of DCZ0825 in vitro and in vivo:involvement of the PI3K‒AKT‒mTOR/JNK pathway显示文摘Diffuse large B-cell lymphoma(DLBCL)is the most common type of non-Hodgkin lymphoma,characterized by high heterogeneity.The poor outcome of a portion of patients who suffer relapsing or resistant to conventional treatment impels the development of novel agents for DLBCL.DCZ0825 is a novel compound derived from pterostilbene and osalmide,whose antitumor activities have drawn our attention.In this study,we found that DCZ0825 exhibited high cytotoxicity toward DLBCL cell lines in a dose-and time-dependent manner,as revealed by cell counting kit-8 assay.Flow cytometry and western blot analysis results showed that DCZ0825 also promoted cell apoptosis via both extrinsic and intrinsic apoptosis pathways mediated by caspase.In addition,DCZ0825 induced cell cycle arrest in the G2/M phase by downregulating Cdc25C,CDK1,and Cyclin B1,thus interfering with cell proliferation.Further investigation showed the involvement of the phosphatidylinositol 3-kinase(PI3K)‒AKT‒mTOR/JNK pathway in the efficacy of DCZ0825 against DLBCL.Remarkably,DCZ0825 also exerted notable cytotoxic effects in vivo as well,with low toxicity to important internal organs such as the liver and kidney.Our results suggest that DCZ0825 may have the potential to become a novel anti-DLBCL agent or to replenish the conventional therapeutic scheme of DLBCL.Ke Hu Bo Li Ruye Ma Hongfei Yi Zhijian Xu Yu Peng Dandan Yu Huiqun Wu Taofang Cheng Yumeng Lu Yong Zhang Rong Wei Guang Yang Xiaosong Wu Weiliang Zhu Jumei Shi 2021Acta Biochimica et Biophysica Sinica2021,53,5:1
