1The mechanism and risk factors for immune checkpoint inhibitor pneumonitis in non-small cell lung cancer patients显示文摘Immune checkpoint inhibitors(ICIs)are new and promising therapeutic agents for non-small cell lung cancer(NSCLC).However,along with demonstrating remarkable efficacy,ICIs can also trigger immune-related adverse events.Checkpoint inhibitor pneumonitis(CIP)has been reported to have a morbidity rate of 3%to 5%and a mortality rate of 10%to 17%.Moreover,the incidence of CIP in NSCLC is higher than that in other tumor types,reaching 7%to 13%.With the increased use of ICIs in NSCLC,CIP has drawn extensive attention from oncologists and cancer researchers.Identifying high risk factors for CIP and the potential mechanism of CIP are key points in preventing and monitoring serious adverse events.In this review,the results of our analysis and summary of previous studies suggested that the risk factors for CIP may include previous lung disease,prior thoracic irradiation,and combinations with other drugs.Our review also explored potential mechanisms closely related toCIP,including increasedT cell activity against associated antigens in tumor and normal tissues,preexisting autoantibodies,and inflammatory cytokines.Xiaoyang Zhai Jian Zhang Yaru Tian Ji Li Wang Jing Hongbo Guo Hui Zhu 2020Cancer Biology & Medicine2020,17,3:25
2Recombinant Newcastle disease virus expressing African swine fever virus protein 72 is safe and immunogenic in mice显示文摘African swine fever(ASF) is a lethal hemorrhagic disease that affects wild and domestic swine. The etiological agent of ASF is African swine fever virus(ASFV). Since the first case was described in Kenya in 1921, the disease has spread to many other countries. No commercial vaccines are available to prevent ASF. In this study, we generated a recombinant Newcastle disease virus(r NDV) expressing ASFV protein 72(p72) by reverse genetics and evaluated its humoral and cellular immunogenicity in a mouse model. The recombinant virus, r NDV/p72, replicated well in embryonated chicken eggs and was safe to use in chicks and mice. The p72 gene in r NDV/p72 was stably maintained through ten passages. Mice immunized with r NDV/p72 developed high titers of ASFV p72 specific Ig G antibody, and had higher levels of Ig G1 than IgG2 a. Immunization also elicited T-cell proliferation and secretion of IFN-γ and IL-4. Taken together, these results indicate that r NDV expressing ASFV p72 might be a potential vaccine candidate for preventing ASF.Xinxin Chen Jifei Yang Yanhong Ji Edward Okoth Bin Liu Xiaoyang Li Hong Yin Qiyun Zhu 2016Virologica Sinica2016,31,2:18
3Phase 1 clinical trial demonstrated that MUC1 positive metastatic seminal vesicle cancer can be effectively eradicated by modified Anti-MUC1 chimeric antigen receptor transduced T cells显示文摘Recent progress in chimeric antigen receptor-modified T-cell(CAR-T cell) technology in cancer therapy is extremely promising, especially in the treatment of patients with B-cell acute lymphoblastic leukemia. In contrast, due to the hostile immunosuppressive microenvironment of a solid tumor, CAR T-cell accessibility and survival continue to pose a considerable challenge, which leads to their limited therapeutic efficacy. In this study, we constructed two anti-MUC1 CAR-T cell lines. One set of CAR-T cells contained SM3 single chain variable fragment(sc Fv) sequence specifically targeting the MUC1 antigen and co-expressing interleukin(IL) 12(named SM3-CAR). The other CAR-T cell line carried the SM3 sc Fv sequence modified to improve its binding to MUC1 antigen(named p SM3-CAR) but did not co-express IL-12. When those two types of CAR-T cells were injected intratumorally into two independent metastatic lesions of the same MUC1+ seminal vesicle cancer patient as part of an interventional treatment strategy, the initial results indicated no side-effects of the MUC1 targeting CAR-T cell approach, and patient serum cytokines responses were positive. Further evaluation showed that p SM3-CAR effectively caused tumor necrosis, providing new options for improved CAR-T therapy in solid tumors.Fengtao You Licui Jiang Bozhen Zhang Qiang Lu Qiao Zhou Xiaoyang Liao Hong Wu Kaiqi Du Youcai Zhu Huimin Meng Zhishu Gong Yunhui Zong Lei Huang Man Lu Jirong Tang Yafen Li Xiaochen Zhai Xiangling Wang Sisi Ye Dan Chen Lei Yuan Lin Qi Lin Yang 2016Science China(Life Sciences)2016,59,4:16
4Whole-Genome Resequencing of a Worldwide Collection of Rapeseed Accessions Reveals the Genetic Basis of Ecotype Divergence显示文摘Rapeseed (Brassica napus),an important oilseed crop,has adapted to diverse climate zones and latitudes by forming three main ecotype groups,namely winter,semiwinter,and spring types. However,genetic variations underlying the divergence of these ecotypes are largely unknown. Here,we report the global pattern of genetic polymorphisms in rapeseed determined by resequencing a worldwide collection of 991 germplasm accessions.A total of 5.56 and 5.53 million singlenucleotide polymorphisms (SNPs)as Well as 1.86 and 1.92 million InDels were identified by mapping reads to the reference genomes of 'Darmor-bzh'and 'Tapidor,'respectively.We generated a map of allelic drift paths that shows splits and mixtures of the main populations,and revealed an asymmetric evolution of the two subgenomes of B.napus by calculating the genetic diversity and linkage disequilibrium parameters.Selective-sweep analysis revealed genetic changes in genes orthologous to those regulating various aspects of plant development and response to stresses.A genome-wide association study identified SNPs in the promoter regions of FLOWERING LOCUS T and FLOWERING LOCUS C orthologs that corresponded to the different rapeseed ecotype groups. Our study provides important insights into the genomic footprints of rapeseed evolution and flowering-time divergence among three ecotype groups,and will facilitate screening of molecular markers for accelerating rapeseed breeding.Dezhi Wu Zhe Liang Tao Yan Ying Xu Lijie Xuan Juan Tang Gang Zhou Ulrike Lohwasser Shuijin Hua Haoyi Wang Xiaoyang Chen Qian Wang Le Zhu Antony Maodzeka Nazim Hussain Zhilan Li Xuming Li Imran Haider Shamsi Ghulam Jilani Linde Wu Hongkun Zheng Guoping Zhang Boulos Chalhoub Lisha Shen Hao Yu Lixi Jiang 2019Molecular Plant2019,12,1:10
5Clinical study using mesenchymal stem cells for the treatment of patients with severe COVID-19显示文摘The coronavirus disease 2019(COVID-19)caused by SARS-CoV-2 was identified in December 2019.The symptoms include fever,cough,dyspnea,early symptom of sputum,and acute respiratory distress syndrome(ARDS).Mesenchymal stem cell(MSC)therapy is the immediate treatment used for patients with severe cases of COVID-19.Herein,we describe two confirmed cases of COVID-19 in Wuhan to explore the role of MSC in the treatment of COVID-19.MSC transplantation increases the immune indicators(including CD4 and lymphocytes)and decreases the inflammation indicators(interleukin-6 and C-reactive protein).High-flow nasal cannula can be used as an initial support strategy for patients with ARDS.With MSC transplantation,the fracrion of inspired O2(Fi02)of the two patients gradually decreased while the oxygen saturation(Sa02)and partial pressure of oxygen(P02)improved.Additionally,the patients9 chest computed tomography showed that bilateral lung exudate lesions were adsorbed after MSC infusion.Results indicated that MSC transplantation provides clinical data on the treatment of COVID-19 and may serve as an alternative method for treating COVID-19,particularly in patients with ARDS.Lingling Tang Yingan Jiang Mengfei Zhu Lijun Chen Xiaoyang Zhou Chenliang Zhou Peng Ye Xiaobei Chen Baohong Wang Zhenyu Xu Qiang Zhang Xiaowei Xu Hainv Gao Xiaojun Wu Dong Li Wanli Jiang Jingjing Qu Charlie Xiang Lanjuan Li 2020Frontiers of Medicine2020,14,5:8
6The interaction of CpEBF1 with CpMADSs is involved in cell wall degradation during papaya fruit ripening显示文摘Ethylene plays a pivotal role in climacteric fruit ripening;whereas 1-MCP,a non-toxic antagonist of ethylene,prevents ethylene-dependent responses and fruit ripening.In this study,a short-term treatment(1 h)with 400 nL L^(−1)1-MCP delayed the ripening of harvested papaya.However,long-term application of 1-MCP(400 nL L^(−1),16 h)resulted in abnormal fruit ripening,with the fruits exhibiting normal yellowing without softening,significantly higher cellulose and lignin contents,and intact cell walls(CW).Furthermore,we found that long-term treatment with 1-MCP significantly inhibited the expression of CpEBF1,an EIN3-binding F-box-1 gene.A protein interaction analysis using yeast two-hybrid,BiFC and GST pull-down assays showed that CpEBF1 interacts with the CpMADS1/3 and CpEIL1 proteins.The interaction of CpEBF1 with CpMADS1/3 further activated the activities of CW-degradation gene promoters.Subcellular localization showed that these proteins were localized in the nucleus.Additionally,the expression levels of CpMADS1/3,CpEIL1,and several CW-degradation-related genes were significantly downregulated by long-term 1-MCP treatment.Therefore,we propose that the inhibited expression of CpEBF1 and CpMADS1/3 resulted in the repressed activation of CW-degradation-related genes via their interaction,thereby resulting in fruit softening disorders.Xiaochun Ding Xiaoyang Zhu Lanlan Ye Shuangling Xiao Zhenxian Wu Weixin Chen Xueping Li 2019Horticulture Research2019,6,1:7

8Deubiquitinase JOSD2 stabilizes YAP/TAZ to promote cholangiocarcinoma progression显示文摘Cholangiocarcinoma(CCA)has emerged as an intractable cancer with scanty therapeutic regimens.The aberrant activation of Yes-associated protein(YAP)and transcriptional co-activator with PDZ-binding motif(TAZ)are reported to be common in CCA patients.However,the underpinning mechanism remains poorly understood.Deubiquitinase(DUB)is regarded as a main orchestrator in maintaining protein homeostasis.Here,we identified Josephin domain-containing protein 2(JOSD2)as an essential DUB of YAP/TAZ that sustained the protein level through cleavage of polyubiquitin chains in a deubiquitinase activity-dependent manner.The depletion of JOSD2 promoted YAP/TAZ proteasomal degradation and significantly impeded CCA proliferation in vitro and in vivo.Further analysis has highlighted the positive correlation between JOSD2 and YAP abundance in CCA patient samples.Collectively,this study uncovers the regulatory effects of JOSD2 on YAP/TAZ protein stabilities and profiles its contribution in CCA malignant progression,which may provide a potential intervention target for YAP/TAZ-related CCA patients.Meijia Qian Fangjie Yan Weihua Wang Jiamin Du Tao Yuan Ruilin Wu Chenxi Zhao Jiao Wang Jiabin Lu Bo Zhang Nengming Lin Xin Dong Xiaoyang Dai Xiaowu Dong Bo Yang Hong Zhu Qiaojun He 2021Acta Pharmaceutica Sinica B2021,11,12:5
9Pyridine-induced interfacial structural transformation of tetraphenylethylene derivatives investigated by scanning tunneling microscopy显示文摘The two-dimensional self-assembly behaviors of tetraphenylethylene (TPE)molecules are significant for further applications, but reports are rare. The self-assembled structures of two C2-symmetry TPE derivatives (H4TCPE and H4ETrC)possessing propeller structures and their stimulus responses to the additionof vinylpyridine derivatives were thoroughly studied with the assistance ofscanning tunneling microscopy (STM) technique in combination with densityfunctional theory (DFT) calculations. Although their chemical structures weresimilar, the H4TCPE and H4ETTC molecules self-assembled into closely packedlamellar and quadrilateral structures, respectivel3~ at the 1-heptanoic acid/HOPGinterface. After the addition of pyridine derivatives (DPE, PEBP-C4, andPEBP-C8), H4TCPE and H4ETTC showed different responsiveness resultingin different co-assembly structures. The results indicated that the structuresof pyridine derivatives--including backbones and substituents--affected theintermolecular interactions of both H4TCPE/pyridine and H4ETTC/pyridinesystems. The modification of the self-assembly behaviors of propeller-shapedI-hTCPE and H4ETTC would contribute to the construction of more complexmultilevel nanostructures.Xuan Peng Linxiu Cheng Xiaoyang Zhu Yanfang Geng Fengying Zhao Kandong Hu Xuan Guo Ke Deng Qingdao Zeng 2018Nano Research2018,11,11:4
10High-sensitive and temperature-self-calibrated tilted fiber grating biological sensing probe显示文摘High sensitivity biological sample measurement has been achieved by using a 10° tilted fiber Bragg grating sensing probe. Human acute leukemia cells with different intracellular densities were clearly discriminated by identifying their slight refraction index (RI) perturbations in the range from 1.3342 to 1.3344, combining with a temperature self-calibration property. We studied the relationship between the intracellular density of cells (S50 and S60) and their RIs, the experimental results provide a potential way to verify the hypothesis for 'density alteration in non-physiological cells (DANCE)'.LIU Fu GUO Tuan LIU JianGuo ZHU XiaoYang LIU Yu GUAN BaiOu ALBERT Jacques 2013Chinese Science Bulletin2013,58,21:3
11Targeting slug-mediated non-canonical activation of c-Met to overcome chemo-resistance in metastatic ovarian cancer cells显示文摘Metastasis-associated drug resistance accounts for high mortality in ovarian cancer and remains to be a major barrier for effective treatment. In this study, SKOV3/T4, a metastatic subpopulation of ovarian cancer SKOV3 cells, was enriched to explore potential interventions against metastaticassociated drug resistance. Quantitative genomic and functional analyses were performed and found that slug was significantly increased in the SKOV3/T4 subpopulation and contributed to the high resistance of SKOV3/T4. Further studies showed that slug activated c-Met in a ligand-independent manner due to elevated levels of fibronectin and provoked integrin α V function, which was confirmed by the significant correlation of slug and p-Met levels in 121 ovarian cancer patient samples. Intriguingly,c-Met inhibitor(s) exhibited greatly enhanced anti-cancer effects in slug-positive ovarian cancer models both in vitro and in vivo. Additionally, IHC analyses revealed that slug levels were highly correlated with reduced survival of ovarian cancer patients. Taken together, this study not only uncovers the critical roles of slug in drug resistance in ovarian cancer but also highlights a promising therapeutic strategy by targeting the noncanonical activation of c-Met in slug-positive ovarian cancer patients with poor prognosis.Linlin Chang Yan Hu Yingying Fu Tianyi Zhou Jun You Jiamin Du Lin Zheng Ji Cao Meidan Ying Xiaoyang Dai Dan Su Qiaojun He Hong Zhu Bo Yang 2019Acta Pharmaceutica Sinica B2019,9,3:3
12Cobalt and Titanium substituted SrFeO_(3) based perovskite as efficient symmetrical electrode for solid oxide fuel cell显示文摘One of the key tasks in solid oxide fuel cell research is to develop cost-competitive electrodes that work efficiently in wide range of air and fuel utilizations.Herein,we promote our study to a series of Cobalt and Titanium substituted La_(0.4)Sr_(0.6)Fe_(0.7)Ti_(0.3-x)Co_(x)O_(3-δ)(LSFTC,x=0,0.05,0.1,0.2)perovskite oxides.It is shown that Cobalt doping effectively improves the electrical conductivity and oxygen electrochemical reduction activity,yielding decreased cathode polarization resistance and lower dependence of pO_(2) change.For example,σ_(600℃)=81 S/cm and R_(p,C750℃)=0.1 Ω cm^(2) for LSFTC-5 are obtained in pO_(2)=0.21 atm.In anode conditions of wet H2,the LSFTC cubic perovskites are partially reduced to hybrid structure of ABO_(3)-A_(2)BO_(4)-metal with Cobalt doping amount less than 10% and are fully decomposed to A_(2)BO_(4)-metal with 20% doping.The higher Cobalt substitution generates more nano particles exsolution,which promotes anode processes at low temperatures.However,the generated AO-rich compositions are shown detrimental to anode performance in both conducting property and anode catalytic activity under low H_(2) partial pressures.In current study,the electrodes are evaluated under practical working conditions with broad pO_(2) and pH_(2),which provides guidelines for industrial-applicable SrFeO_(3) based symmetrical electrode development.Jianing Song Tenglong Zhu Xiaoyang Chen Weijie Ni Qin Zhong 2020Journal of Materiomics2020,6,2:3
13Influence of Particles on the Loading Capacity and the Temperature Rise of Water Film in Ultra-high Speed Hybrid Bearing显示文摘Ultra-high speed machining technology enables high efficiency, high precision and high integrity of machined surface. Previous researches of hybrid bearing rarely consider influences of solid particles in lubricant and ultra-high speed of hybrid bearing, which cannot be ignored under the high speed and micro-space conditions of ultra-high speed water-lubricated hybrid bearing. Considering the impact of solid particles in lubricant, turbulence and temperature viscosity effects of lubricant, the influences of particles on pressure distribution, loading capacity and the temperature rise of the lubricant film with four-step-cavity ultra-high speed water-lubricated hybrid bearing are presented in the paper. The results show that loading capacity of the hybrid bearing can be affected by changing the viscosity of the lubricant, and large particles can improve the bearing loading capacity higher. The impact of water film temperature rise produced by solid particles in lubricant is related with particle diameter and minimum film thickness. Compared with the soft particles, hard particles cause the more increasing of water film temperature rise and loading capacity. When the speed of hybrid bearing increases, the impact of solid particles on hybrid bearing becomes increasingly apparent, especially for ultra-high speed water-lubricated hybrid bearing. This research presents influences of solid particles on the loading capacity and the temperature rise of water film in ultra-high speed hybrid bearings, the research conclusions provide a new method to evaluate the influence of solid particles in lubricant of ultra-high speed water-lubricated hybrid bearing, which is important to performance calculation of ultra-high speed hybrid bearings, design of filtration system, and safe operation of ultra-high speed hybrid bearings.ZHU Aibin LI Pei ZHANG Yefan CHEN Wei YUAN Xiaoyang 2015Chinese Journal of Mechanical Engineering2015,28,3:2

15The C/EBPβ-Dependent Induction of TFDP2 Facilitates Porcine Reproductive and Respiratory Syndrome Virus Proliferation显示文摘Porcine reproductive and respiratory syndrome(PRRS) is an important infectious disease caused by porcine reproductive and respiratory syndrome virus(PRRSV), leading to significant economic losses in swine industry worldwide. Although several studies have shown that PRRSV can affect the cell cycle of infected cells, it is still unclear how it manipulates the cell cycle to facilitate its proliferation. In this study, we analyzed the mRNA expression profiles of transcription factors in PRRSV-infected 3D4/21 cells by RNA-sequencing. The result shows that the expression of transcription factor DP2(TFDP2) is remarkably upregulated in PRRSV-infected cells. Further studies show that TFDP2 contributes to PRRSV proliferation and the PRRSV nucleocapsid(N) protein induces TFDP2 expression by activating C/EBPb. TFDP2 positively regulates cyclin A expression and triggers a less proportion of cells in the S phase, which contributes to PRRSV proliferation. This study proposes a novel mechanism by which PRRSV utilizes host protein to regulate the cell cycle to favor its infection. Findings from this study will help us for a better understanding of PRRSV pathogenesis.Min Zhu Xiaoyang Li Ruiqi Sun Peidian Shi Aiping Cao Lilin Zhang Yanyu Guo Jinhai Huang 2021Virologica Sinica2021,36,6:2
16Directionality based fast fractional pel motion estimation for H.264显示文摘Motion estimation is an important and intensive task in video coding applications.Since the complexity of integer pixel search has been greatly reduced by the numerous fast ME algorithm,the computation overhead required by fractional pixel ME has become relatively significant.To reduce the complexity of the fractional pixel ME algorithm,a directionality-based fractional pixel ME algorithm is proposed.The proposed algorithm efficiently explores the neighborhood positions which with high probability to be the best matching around the minimum one and skips over other unlikely ones.Thus,the proposed algorithm can complete the search by examining only 3 points on appropriate condition instead of 17 search points in the search algorithm of reference software.The simulation results show that the proposed algorithm successfully optimizes the fractional-pixel motion search on both half and quarter-pixel accuracy and improves the processing speed with low PSNR penalty.Zhang Wei Fan Fen Wang Xiaoyang Zhu Weile 2009Journal of Systems Engineering and Electronics2009,20,3:2
17The C_(6)D_(6)detector system on the Back-n beam line of CSNS显示文摘Introduction The neutron capture cross sections are very important in the field of nuclear device design and basic physics research.Hydrogen-free liquid scintillator such as C_(6)D_(6)detectors are widely used in the neutron capture cross-sectional measurements for the low neutron sensitivity and fast time response.The Back-n white neutron source at China Spallation Neutron Source is the first spallation white neutron source in China,and it is suitable for neutron capture cross-sectional measurement.Materials and methods A C_(6)D_(6)detector system was built in the Back-n experimental station.The pulse height weighting technique was used to determine the system’s detection efficiency.The response to gamma rays of the C_(6)D_(6)detector was measured,and the energy resolution function was determined.Monte Carlo simulation with Geant4 code was carried out to get the weighting function of this C_(6)D_(6)detector system.Additionally,the systematic uncertainty of the weighting function was also determined.Conclusion According to the experimental and simulation results,this C_(6)D_(6)detector system can be used to measure neutron capture cross section.Jie Ren Xichao Ruan Jie Bao Guangyuan Luan Wei Jiang Qi An Huaiyong Bai Ping Cao Qiping Chen Yonghao Chen Pinjing Cheng Zengqi Cui Ruirui Fan Changqing Feng Minhao Gu Fengqin Guo Changcai Han Zijie Han Guozhu He Yongcheng He Yuefeng He Hanxiong Huang Weiling Huang Xiru Huang Xiaolu Ji Xuyang Ji Haoyu Jiang Hantao Jing Ling Kang Mingtao Kang Bo Li Lun Li Qiang Li Xiao Li Yang Li Yang Li Rong Liu Shubin Liu Xingyan Liu Yinglin Ma Changjun Ning Binbin Qi Zhaohui Song Hong Sun Xiaoyang Sun Zhijia Sun Zhixin Tan Hongqing Tang Jingyu Tang Pengcheng Wang Qi Wang Taofeng Wang Yanfeng Wang Zhaohui Wang Zheng Wang Jie Wen Zhongwei Wen Qingbiao Wu Xiaoguang Wu Xuan Wu Likun Xie Yiwei Yang Han Yi Li Yu Tao Yu Yongji Yu Guohui Zhang Jing Zhang Linhao Zhang Liying Zhang Qingmin Zhang Qiwei Zhang Xianpeng Zhang Yuliang Zhang Zhiyong Zhang Yingtan Zhao Liang Zhou Zuying Zhou Danyang Zhu Kejun Zhu Peng Zhu 2019Radiation Detection Technology and Methods2019,3,3:1

19Fabrication of metal oxide nanostructures based on Atomic Force Microscopy lithography显示文摘Atomic Force Microscopy (AFM) mechanical lithography is a simple but significant method for nanofabrication. In this work, we used this method to construct nanos- tructures on Pt/Cu bilayer metal electrodes under ambient conditions in air. The influence of various scratch parameters, such as the applied force, scan velocity and circle times, on the lithography patterns was investigated. The Pt-Cu-CuxO-Cu-Pt nanostructure was constructed by choosing suitable scratch parameters and oxidation at room temperature. The properties of the scratched regions were also investigated by friction force microscopy and conductive AFM (C-AFM). The I-V curves show symmetric and linear properties, and Ohmic contacts were formed. These results indicate that AFM mechanical lithography is a powerful tool for fabricating novel metal-semiconductor nanoelectronic devices.ZHU XiaoYang CHENG Gang WANG ShuJie DAI ShuXi WAN ShaoMing ZHANG XingTang DU ZuLiang 2008Science China(Physics,Mechanics & Astronomy)2008,51,10:1
