| 1 | Energy-Efficient Multi-UAV Coverage Deployment in UAV Networks:A Game-Theoretic Framework显示文摘UAV cooperative control has been applied in many complex UAV communication networks. It remains challenging to develop UAV cooperative coverage and UAV energy-efficient communication technology. In this paper, we investigate current works about UAV coverage problem and propose a multi-UAV coverage model based on energy-efficient communication. The proposed model is decomposed into two steps: coverage maximization and power control, both are proved to be exact potential games(EPG) and have Nash equilibrium(NE) points. Then the multi-UAV energy-efficient coverage deployment algorithm based on spatial adaptive play(MUECD-SAP) is adopted to perform coverage maximization and power control, which guarantees optimal energy-efficient coverage deployment. Finally, simulation results show the effectiveness of our proposed approach, and confirm the reliability of proposed model. | Lang Ruan Jinlong Wang Jin Chen Yitao Xu Yang Yang Han Jiang Yuli Zhang Yuhua Xu | 2018 | China Communications2018，15，10： | 24 |
| 2 | Endovascular stent-induced alterations in host artery mechanical environments and their roles in stent restenosis and late thrombosis显示文摘Cardiovascular stent restenosis remains a major challenge in interventional treatment of cardiovascular occlusive disease.Although the changes in arterial mechanical environment due to stent implantation are the main causes of the initiation of restenosis and thrombosis,the mechanisms that cause this initiation are still not fully understood.In this article,we reviewed the studies on the issue of stent-induced alterations in arterial mechanical environment and discussed their roles in stent restenosis and late thrombosis from three aspects:(i)the interaction of the stent with host blood vessel,involve the response of vascular wall,the mechanism of mechanical signal transmission,the process of re-endothelialization and late thrombosis;(ii)the changes of hemodynamics in the lumen of the vascular segment and(iii)the changes of mechanical microenvironment within the vascular segment wall due to stent implantation.This review has summarized and analyzed current work in order to better solve the two main problems after stent implantation,namely in stent restenosis and late thrombosis,meanwhile propose the deficiencies of current work for future reference. | Jinxuan Wang Xuepu Jin Yuhua Huang Xiaolin Ran Desha Luo Dongchuan Yang Dongyu Jia Kang Zhang Jianhua Tong Xiaoyan Deng Guixue Wang | 2018 | Regenerative Biomaterials2018，5，3： | 13 |
| 3 | Climatic variation of tropical cyclones affecting China during the past 50 years显示文摘Trends of the tropical cyclones (TCs) influence on China and its four subregions,namely the South China (SC),East China (EC),Northeast China (NEC),and China's inland area (CI),are detected by applying quantile regression to the CMA-STI tropical cyclone best track and related severe wind and precipitation observation datasets.The results indicate that in the past 50 years,the number of TCs affecting China and its four subregions has remained steady,except that the frequency in extremely active years has decreased not only in China as a whole,but also in NEC.In addition,TC activity is found to have weakened over the northwest South China Sea,Guangdong,and Shandong Peninsula.However,the most important changes in seasonality are found in the first quartiles of the number of days of TCs affecting CI.While the extreme values of sustained winds all have decreasing trends,the extreme values of wind gusts are completely different not only among different orders of extreme values,but also among different subregions.However,the trends of extreme TC rainfall,namely the maximum storm precipitation and the maximum 1-h precipitation,are not significant. | YING Ming YANG YuHua CHEN BaoDe ZHANG Wei | 2011 | Science China Earth Sciences2011，54，8： | 8 |
| 4 | DELLA and EDS1 Form a Feedback Regulatory Module to Fine-Tune Plant Growth-Defense Tradeoff in Arabidopsis显示文摘Plants maintain a dynamic balance between growth and defense,and optimize allocation of resources for survival under constant pathogen infections.However,the underlying molecular regulatory mechanisms,especially in response to biotrophic bacterial infection,remain elusive.Here,we demonstrate that DELLA proteins and EDS1,an essential resistance regulator,form a central module modulating plant growth-defense tradeoffs via direct interaction.When infected by Pst DC3000,EDS1 rapidly promotes salicylic acid(SA)biosynthesis and resistance-related gene expression to prime defense response,while pathogen infection stabilizes DELLA proteins RGA and RGL3 to restrict growth in a partially EDS1-dependent manner,which facilitates plants to develop resistance to pathogens.However,the increasingly accumulated DELLAs interact with EDS1 to suppress SA overproduction and excessive resistance response.Taken together,our findings reveal a DELLA-EDS1-mediated feedback regulatory loop by which plants maintain the subtle balance between growth and defense to avoid excessive growth or defense in response to constant biotrophic pathogen attack. | Yuge Li Yuhua Yang Yilong Hu Hailun Liu Ming He Ziyin Yang Fanjiang Kong Xu Liu Xingliang Hou | 2019 | Molecular Plant2019，12，11： | 8 |
| 5 | Efficient hepatic delivery and protein expression enabled by optimized mRNA and ionizable lipid nanoparticle显示文摘mRNA is a novel class of therapeutic modality that holds great promise in vaccination,protein replacement therapy,cancer immunotherapy,immune cell engineering etc.However,optimization of mRNA molecules and efficient in vivo delivery are quite important but challenging for its broad application.Here we present an ionizable lipid nanoparticle(iLNP)based on iBL0713 lipid for in vitro and in vivo expression of desired proteins using codon-optimized mRNAs.mRNAs encoding luciferase or erythropoietin(EPO)were prepared by in vitro transcription and formulated with proposed iLNP,to form iLP171/mRNA formulations.It was revealed that both luciferase and EPO proteins were successfully expressed by human hepatocellular carcinoma cells and hepatocytes.The maximum amount of protein expression was found at 6 h post-administration.The expression efficiency of EPO with codon-optimized mRNA was significantly higher than that of unoptimized mRNA.Moreover,no toxicity or immunogenicity was observed for these mRNA formulations.Therefore,our study provides a useful and promising platform for mRNA therapeutic development. | Tongren Yang Chunhui Li Xiaoxia Wang Deyao Zhao Mengjie Zhang Huiqing Cao Zicai Liang Haihua Xiao Xing-Jie Liang Yuhua Weng Yuanyu Huang | 2020 | Bioactive Materials2020，5，4： | 7 |
| 6 | External fixation is more suitable for intra-articular fractures of the distal radius in elderly patients显示文摘The purpose of this study was to compare the functional outcomes,psychological impact,and complication rates associated with external fixation and volar or dorsal plating in relation to the functional parameters following treatment of intra-articular fractures of the distal radius(IFDR) in patients older than 65 years.We hypothesized that using volar or dorsal plating would improve functional outcomes,but that it would be associated with more complications and equivalent functional outcomes when compared with the external fixation group.A total of 123 consecutive patients suffering from IFDR were recruited into the study.The patients were measured for clinical,radiological,and psychosocial functioning outcomes and were followed up after 1 week and 3,6 and 12 months.After 3 months,the plating group had better pronation(P=0.001),supination,(P=0.047) and extension(P=0.043) scores.These differences were somewhat attenuated by6 months and disappeared at 1 year.The plating group had a greater occurrence of wound infection(P=0.043),tendonitis,(P=0.024) and additional surgery compared with the external fixation group.The only TNO-AZL Adult Quality of Life scores in the plating group that were lower than those in the external fixation group were in the 'gross motor' category(walking upstairs,bending over,walking 500 yards; P=0.023).Internal fixation was more advantageous than external fixation in the early rehabilitation period; after 1 year the outcomes were similar.The plating group showed significantly higher levels of wound infection and tendonitis and had a greater need for additional surgeries. | Chuang Ma Qiang Deng Hongwei Pu Xinchun Cheng Yuhua Kan Jing Yang Aihemaitijiang Yusufu Li Cao | 2016 | Bone Research2016，4，1： | 7 |

| 8 | State-of-the-Art Review of High-Throughput Statistical Spatial-Mapping Characterization Technology and Its Applications显示文摘Macroscopic materials are heterogeneous,multi-elementary,and complex.No material is homogeneous or isotropic at a certain small scale.Parts of the material that differ from one another can be termed'natural chips.'At different spots on the material,the composition,structure,and properties vary slightly,and the combination of these slight differences establishes the overall material performance.This article presents a state-of-the-art review of research and applications of high-throughput statistical spatialmapping characterization technology based on the intrinsic heterogeneity within materials.Highthroughput statistical spatial-mapping uses a series of rapid characterization techniques for analysis from the macroscopic to the microscopic scale.Datasets of composition,structure,and properties at each location are obtained rapidly for practical sample sizes.Accurate positional coordinate information and references to a point-to-point correspondence are used to set up a database that contains spatialmapping lattices.Based on material research and development design requirements,dataset spatialmapping within required target intervals is selected from the database.Statistical analysis can be used to select a suitable design that better meets the targeted requirements.After repeated verification,genetic units that reflect the material properties are determined.By optimizing process parameters,the assembly of these genetic unit(s)is verified at the mesoscale,and quantitative correlations are established between the microscale,mesoscale,macroscale,practical sample,across-the-scale span composition,structure,and properties.The high-throughput statistical spatial-mapping characterization technology has been applied to numerous material systems,such as steels,superalloys,galvanization,and ferrosilicon alloys.This approach has guided the composition and the process optimization of various materials. | Haizhou Wang Lei Zhao Yunhai Jia Dongling Li Lixi Yang Yuhua Lu Guang Feng Weihao Wan | 2020 | Engineering2020，6，6： | 7 |
| 9 | Carbon Stock of Larch Plantations and Its Comparison with an Old-growth Forest in Northeast China显示文摘The overall goal of this study was to understand carbon(C) stock dynamics in four different-aged Japanese larch(Larix kaempferi) plantations in Northeast China that were established after clear-cutting old-growth Korean pine deciduous forests. Four Japanese larch plantations which were at 10, 15, 21, and 35 years old and an old-growth Korean pine deciduous forest which was 300 years old in Northeast China were selected and sampled. We compared the C pools of biomass(tree, shrub and herb), litterfall(LF), and soil organic carbon(SOC) among them. The biomass C stock of larch plantation at 10, 15, 21, and 35 years old was 26.8, 37.9, 63.6, and 83.2 Mg/ha, respectively, while the biomass C stock of the old-growth Korean pine deciduous forest was 175.1 Mg/ha. The SOC stock of these larch plantations was 172.1, 169.7, 140.3, and 136.2 Mg/ha respectively, and SOC stock of 170.4 Mg/ha in the control of old-growth forest. The biomass C stock increased with stand age of larch plantations, whereas SOC stock decreased with age, and C stock of LF did not change significantly(P > 0.05). The increase of biomass C offset the decline of SOC stock with age, making total carbon stock(TCS) of larch plantations stable from stand ages of 10–35 years. The TCS in larch plantations was much smaller than that in the old-growth forest, suggesting that the conversion of old-growth forests to young larch plantations releases substantial C into the atmosphere. | QI Guang CHEN Hua ZHOU Li WANG Xinchuang ZHOU Wangming QI Lin YANG Yuhua YANG Fengling WANG Qingli DAI Limin | 2016 | Chinese Geographical Science2016，26，1： | 6 |
| 10 | Cranial irradiation impairs intrinsic excitability and synaptic plasticity of hippocampal CA1 pyramidal neurons with implications for cognitive function显示文摘Radiation therapy is a standard treatment for head and neck tumors.However,patients often exhibit cognitive impairments following radiation therapy.Previous studies have revealed that hippocampal dysfunction,specifically abnormal hippocampal neurogenesis or neuroinflammation,plays a key role in radiation-induced cognitive impairment.However,the long-term effects of radiation with respect to the electrophysiological adaptation of hippocampal neurons remain poorly characterized.We found that mice exhibited cognitive impairment 3 months after undergoing 10 minutes of cranial irradiation at a dose rate of 3 Gy/min.Furthermore,we observed a remarkable reduction in spike firing and excitatory synaptic input,as well as greatly enhanced inhibitory inputs,in hippocampal CA1 pyramidal neurons.Corresponding to the electrophysiological adaptation,we found reduced expression of synaptic plasticity marker VGLUT1 and increased expression of VGAT.Furthermore,in irradiated mice,long-term potentiation in the hippocampus was weakened and GluR1 expression was inhibited.These findings suggest that radiation can impair intrinsic excitability and synaptic plasticity in hippocampal CA1 pyramidal neurons. | Min-Yi Wu Wen-Jun Zou Pei Yu Yuhua Yang Shao-Jian Li Qiang Liu Jiatian Xie Si-Qi Chen Wei-Jye Lin Yamei Tang | 2022 | Neural Regeneration Research2022，17，10： | 5 |

| 12 | Chinese expert consensus on the management of chimeric antigen receptor T cell therapy-associated coagulopathy显示文摘Chimeric antigen receptor T-cell(CAR-T)therapy has greatly improved the disease remission rate and long-term survival rate of patients with relapsed/refractory hematological malignancies.[1-3]Currently,several commercial CAR-T products are available in the market and numerous CAR-T clinical trials have been conducted.Attention should be paid to the safety of CAR-T therapy.The main adverse effects of CAR-T therapy are cytokine release syndrome(CRS)and immune effector cell-associated neurotoxicity syndrome(ICANS).[4] | Heng Mei Fangping Chen Yue Han Ming Hou He Huang Xiaojun Huang Yuhua Li Aibin Liang Qifa Liu Ting Niu Jun Peng Wenbin Qian Yongping Song Jianxiang Wang Ying Wang Depei Wu Kailin Xu Linhua Yang Renchi Yang Lei Zhang Liansheng Zhang Xi Zhang Xiaohui Zhang Weili Zhao Weidong Han Yu Hu | 2022 | Chinese Medical Journal2022，，14： | 4 |
| 13 | “All‐In‐One” integrated ultrathin SnS2@3D multichannel carbon matrix power high‐areal–capacity lithium battery anode显示文摘Construction of a thickness‐independent electrode with high active material mass loading is crucial for the development of high energy rechargeable lithium battery.Herein,we fabricate an all‐in‐one integrated SnS2@3D multichannel carbon matrix(SnS2@3DMCM)electrode with in‐situ growth of ultrathin SnS2 nanosheets inside the inner walls of three dimensional(3D)multichannels.The interconnected conductive carbon matrix derived from natural wood acts as an integrated porous current collector to avail the electrons transport and accommodate massive SnS2 nanosheets,while plenty of 3D aligned multichannels facilitate fast ions transport with electrode thickness‐independent even under high mass loading.As expected,the integrated SnS2@3DMCM electrode exhibits remarkable electrochemical lithium storage performance,such as exceptional high‐areal‐capacity of 6.4 mAh cm−2,high rate capability of 3 mAh cm−2 under current of 6.8 mAcm−2(10 C),and stable cycling performance of 6.8 mAcm−2 with a high mass loading of 7mg cm−2.The 3D integrated porous electrode constructing conveniently with the natural source paves new avenues towards future high‐performance lithium batteries. | Hongyi Xu Chengxin Peng Yuhua Yan Fei Dong Hao Sun Junhe Yang Shiyou Zheng | 2019 | Carbon Energy2019，1，2： | 4 |
| 14 | Opposite effects of miR-155 in the initial and later stages of lipopolysaccharide(LPS)-induced inflammatory response显示文摘Although microRNA-155(miR-155)is considered a pro-inflammatory mediator,cumulative evidence indicates that it also has anti-inflammatory effects in macrophages and dendritic cells.In this study,we identified the dramatic expression changes of more than half of potential miR-155-targeted genes upon lipopolysaccharide(LPS)stimulation;223 genes were down-regulated and 85 genes were up-regulated,including suppressor of cytokine signaling 1(SOCS1)and transforming growth factor-β-activated kinase 1-binding protein 2(TAB2),two well-known genes involved in miR-155-mediated regulation of the Toll-like receptor 4(TLR4)signaling pathway.We also found that miR-155 acted as an anti-inflammatory mediator in the initial stage of LPS-induced inflammatory response mainly through repressing TAB2 protein translation,and as a proinflammatory mediator by down-regulating SOCS1 in the later stage.Meanwhile,overexpression of TAB23'untranslated region(UTR)in macrophages promoted the development of endotoxin tolerance by competing for binding with miR-155,which resulted in an elevated expression level of SOCS1 protein.These findings provide new insights for understanding the regulatory mechanisms in fine-tuning of LPS-induced innate immune response. | Yuhua LIU Xiaopeng WAN Yuan YUAN Jingjing HUANG Yijia JIANG Kaiyue ZHAO Yan WANG Yang LIU Qingqing WANG Hongchuan JIN | 2021 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021，22，7： | 4 |
| 15 | Joining of Zirconia and Ti-6Al-4V Using a Ti-based Amorphous Filler显示文摘Polycrystalline ZrO2-3 mol.%Y2O3 was brazed to Ti-6Al-4V by using a Ti47Zr28Cu14Ni11(at.%) amorphous ribbon at 1123-1273 K in a high vacuum. The influences of brazing temperature on the microstructure and shear strength of the joints were investigated. The interfacial microstructures can be described as ZrO2/TiO+TiO2+Cu2Ti4O+Ni2Ti4O/α-Ti+(Ti,Zr)2(Cu,Ni) eutectic/acicular Widmanst¨aten structure/Ti-6Al-4V alloy. With the increase in the brazing temperature, the thickness of the TiO+TiO2+Cu2Ti4O+Ni2Ti4O layer reduced, the content of the α-Ti+(Ti,Zr)2(Cu,Ni) eutectic phase decreased, while that of the coarse α-Ti phase gradually increased. The shear strength of the joints did not show a close relationship with the thickness of the TiO+TiO2+Cu2Ti4O+Ni2Ti4O layer. However, when the coarse (Ti,Zr)2(Cu,Ni) phase was non-uniformly distributed in the α-Ti phase, or when α-Ti solely situated at the center of the joint, forming a coarse block or even connecting into a continuous strip, the shear strength greatly decreased. | Yuhua Liu Jiandong Hu Yaping Zhang Zuoxing Guo Yue Yang | 2011 | Journal of Materials Science & Technology2011，27，7： | 3 |
| 16 | A super pan-genomic landscape of rice显示文摘Pan-genomes from large natural populations can capture genetic diversity and reveal genomic complexity.Using de novo longread assembly,we generated a graph-based super pan-genome of rice consisting of a 251-accession panel comprising both cultivated and wild species of Asian and African rice.Our pan-genome reveals extensive structural variations(SVs)and gene presence/absence variations.Additionally,our pan-genome enables the accurate identification of nucleotide-binding leucine-rich repeat genes and characterization of their inter-and intraspecific diversity.Moreover,we uncovered grain weight-associated SVs which specify traits by affecting the expression of their nearby genes.We characterized genetic variants associated with submergence tolerance,seed shattering and plant architecture and found independent selection for a common set of genes that drove adaptation and domestication in Asian and African rice.This super pan-genome facilitates pinpointing of lineage-specific haplotypes for trait-associated genes and provides insights into the evolutionary events that have shaped the genomic architecture of various rice species. | Lianguang Shang Xiaoxia Li Huiying He Qiaoling Yuan Yanni Song Zhaoran Wei Hai Lin Min Hu Fengli Zhao Chao Zhang Yuhua Li Hongsheng Gao Tianyi Wang Xiangpei Liu Hong Zhang Ya Zhang Shuaimin Cao Xiaoman Yu Bintao Zhang Yong Zhang Yiqing Tan Mao Qin Cheng Ai Yingxue Yang Bin Zhang Zhiqiang Hu Hongru Wang Yang Lv Yuexing Wang Jie Ma Quan Wang Hongwei Lu Zhe Wu Shanlin Liu Zongyi Sun Hongliang Zhang Longbiao Guo Zichao Li Yongfeng Zhou Jiayang Li Zuofeng Zhu Guosheng Xiong Jue Ruan Qian Qian | 2022 | Cell Research2022，32，10： | 3 |
| 17 | The molecular determinants governing the immunogenicity of Japanese encephalitis live attenuated vaccines显示文摘In the course of isolating the attenuated Japanese encephalitis vaccine SA14-14-2,two attenuated strains SA14-9-7 and SA14-5-3 were also obtained that elicited low antibody responses in humans(o10%and 62%,respectively)and exerted much weaker immune protection in animal challenge experiments.However,the reason for these differences remains unknown.In order to understand why SA14-14-2 is superior to SA14-9-7 and SA14-5-3,we employed a reverse genetics method to identify the key mutations in the virus genome that determine the immunogenicity of live attenuated Japanese encephalitis viruses.We first sequenced the full genomic sequences of SA14-9-7 and SA14-5-3 and found mutations that changed four amino-acid base pairs when compared to the envelope gene of SA14-14-2.We mutated the genome of SA14-14-2 to generate these mutations both singly(E-177,E-264,E-279 and E-315)and in combination(E-177/264,E-279/315 and E-177/264/279/315)and tested these mutants along with parental strains SA14-14-2,SA14-9-7 and SA14-5-3 for their immunogenicity in vivo.When mice were immunized with SA14-9-7 and SA14-5-3,lower levels of neutralizing antibodies were generated compared with the immune response to SA14-14-2.Furthermore,SA14-5-3 was more immunogenic than SA14-9-7,which replicated the results previously seen in humans.Point mutations E-177,E-264,E-279 and E-315 diminished the immunogenicity of SA14-14-2 with E-264 and E-315,contributing the most to this phenotype.The mutant rJEV(E-177/E-264/E-279/E-315)containing all four point mutations exhibited the lowest immunogenicity with a seroconversion rate of 0 at an inoculation dose of 103 PFU(plaque-forming unit).We have identified the key amino acids in the envelope protein that account for the superior immunogenicity of SA14-14-2. | Yuhua Li Yin Fu Xinyu Liu Huiqiang Yang Yongxin Yu Lili Jia Xuguang Li Aaron Farnsworth Junzhi Wang | 2017 | Signal Transduction and Targeted Therapy2017，2，1： | 3 |
| 18 | 2022 Chinese expert consensus and guidelines on clinical management of toxicity in anti-CD19 chimeric antigen receptor T-cell therapy for B-cell non-Hodgkin lymphoma显示文摘Adoptive cellular immunotherapy with chimeric antigen receptor(CAR)T cells has emerged as a novel modality for treating relapsed and/or refractory B-cell non-Hodgkin lymphoma(B-NHL).With increasing approval of CAR T-cell products and advances in CAR T cell therapy,CAR T cells are expected to be used in a growing number of cases.However,CAR T-cell-associated toxicities can be severe or even fatal,thus compromising the survival benefit from this therapy.Standardizing and studying the clinical management of these toxicities are imperative.In contrast to other hematological malignancies,such as acute lymphoblastic leukemia and multiple myeloma,anti-CD19 CAR T-cell-associated toxicities in B-NHL have several distinctive features,most notably local cytokine-release syndrome(CRS).However,previously published guidelines have provided few specific recommendations for the grading and management of toxicities associated with CAR T-cell treatment for B-NHL.Consequently,we developed this consensus for the prevention,recognition,and management of these toxicities,on the basis of published literature regarding the management of anti-CD19 CAR T-cell-associated toxicities and the clinical experience of multiple Chinese institutions.This consensus refines a grading system and classification of CRS in B-NHL and corresponding measures for CRS management,and delineates comprehensive principles and exploratory recommendations for managing anti-CD19 CAR T-cell-associated toxicities in addition to CRS. | Ping Li Yang Liu Yun Liang Jian Bo Sujun Gao Yongxian Hu Yu Hu He Huang Xiaojun Huang Hongmei Jing Xiaoyan Ke Jianyong Li Yuhua Li Qifa Liu Peihua Lu Heng Mei Ting Niu Yongping Song Yuqin Song Liping Su Sanfang Tu Jianxiang Wang Depei Wu Zhao Wang Kailin Xu Zhitao Ying Qingming Yang Yajing Zhang Fengxia Shi Bin Zhang Huilai Zhang Xi Zhang Mingfeng Zhao Weili Zhao Xiangyu Zhao Liang Huang Jun Zhu Wenbin Qian Weidong Han Aibin Liang | 2023 | Cancer Biology & Medicine2023，20，2： | 3 |
| 19 | The efficacy of NP11-4-derived immunotoxin scFv-artesunate in reducing hepatic fibrosis inducedby Schistosoma japonicum in mice显示文摘Schistosomiasis is one of the most prevalent parasitic diseases in China,and hepatic fibrosis caused by schistosome infection is the principal cause of death.The aim of this study was to evaluate the efficacy of NP11-4derived immunotoxin scFv-artesunate on Schistosoma japonicum-induced hepatic fibrosis.A single-chain variable fragment (scFv) was generated from the murine anti-Schistosoma japonicum (S.japanicum) monoclonal antibody NP11-4.The scFv was expressed as a soluble protein and purified by Ni-affinity chromatography.After conjugation with artesunate,the binding ability with soluble egg antigens (SEA) was determined by an enzyme-linked immunosorbent assay (ELISA).The biological activity of purified scFv,scFv-artesunate (immunotoxin),and artesunate was detected in vivo.Image-Pro Plus software was used to analyze the size of egg granuloma and the extent of liver fibrosis.The recombinant scFv expession vector was constructed and expressed successfully.After purification by a His-trap Ni-affinity column,the scFv yield was approximately 0.8 mg/L of culture medium.ELISA results showed that chemical conjugation did not affect the binding activity of the immunotoxin.Our animal experiments indicated that the immunotoxin could significantly reduce the size of egg granuloma in the liver and inhibit hepatic fibrosis.The immunotoxin could be used as a promising candidate in the targeted therapy of S.japonicum-induced hepatic fibrosis. | Hong Li Chunyan Gu Yongya Ren Yang Dai Xiaojuan Zhu Jing Xu Yuhua Li Zhenning Qiu Jin Zhu Yinchang Zhu Xiaohong Guan Zhenqing Feng | 2011 | The Journal of Biomedical Research2011，25，2： | 3 |
| 20 | A core-shell structured COYID-19 mRNA vaccine with favorable biodistribution pattern and promising immunity显示文摘Although inoculation of COVID-19 vaccines has rolled out globally,there is still a critical need for safe and effective vaccines to ensure fair and equitable supply for all countries.Here,we report on the development of a highly efficacious mRNA vaccine,SW0123 that is composed of sequence-modified mRNA encoding the full-length SARS-CoV-2 Spike protein packaged in core-shell structured lipopolyplex(LPP)nanoparticles.SWOT 23 is easy to produce using a large-scale microfluidics-based apparatus.The unique core-shell structured nanoparticle facilitates vaccine uptake and demonstrates a high colloidal stability,and a desirable biodistribution pattern with low liver targeting effect upon intramuscular administration.Extensive evaluations in mice and nonhuman primates revealed strong immunogenicity of SW0123,represented by induction of Th1-polarized T cell responses and high levels of antibodies that were capable of neutralizing not only the wild-type SARS-CoV-2,but also a panel of variants including D614G and N501Y variants.In addition,SW0123 conferred effective protection in both mice and non-human primates upon SARS-CoV-2 challenge.Taken together,SW0123 is a promising vaccine candidate that holds prospects for further evaluation in humans. | Ren Yang Yao Deng Baoying Huang Lei Huang Ang Lin Yuhua Li Wenling Wang Jingjing Liu Shuaiyao Lu Zhenzhen Zhan Yufei Wang Ruhan A Wen Wang Peihua Niu Li Zhao Shiqiang Li Xiaopin Ma Luyao Zhang Yujian Zhang Weiguo Yao Xingjie Liang Jincun Zhao Zhongmin Liu Xiaozhong Peng Hangwen Li Wenjie Tan | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 3 |
