4Structures of EV71 RNA-dependent RNA polymerase in complex with substrate and analogue provide a drug target against the hand-foot-and-mouth disease pandemic in China显示文摘Enterovirus 71(EV71),one of the major causative agents for hand-foot-and-mouth disease(HFMD),has caused more than 100 deaths among Chinese children since March 2008.The EV71 genome encodes an RNAdependent RNA polymerase(RdRp),denoted 3D^(pol),which is central for viral genome replication and is a key target for the discovery of specific antiviral therapeutics.Here we report the crystal structures of EV71 RdRp(3D^(pol))and in complex with substrate guanosine-5'-triphosphate and analog 5-bromouridine-5'-triphosphate best to 2.4Åresolution.The structure of EV71 RdRp(3D^(pol))has a wider open thumb domain compared with the most closely related crystal structure of poliovirus RdRp.And the EV71 RdRp(3D^(pol))complex with GTP or Br-UTP bounded shows two distinct movements of the polymerase by substrate or analogue binding.The model of the complex with the template:primer derived by superimposition with foot-and-mouth disease virus(FMDV)3D/RNA complex reveals the likely recognition and binding of template:primer RNA by the polymerase.These results together provide a molecular basis for EV71 RNA replication and reveal a potential target for anti-EV71 drug discovery.Yang Wu Zhiyong Lou Yi Miao Yue Yu Hui Dong Wei Peng Mark Bartlam Xuemei Li Zihe Rao 2010Protein & Cell2010,1,5:30

9Anatomy of composition and nature of plate convergence: Insights for alternative thoughts for terminal India-Eurasia collision显示文摘The pattern and timing of collision between India and Eurasia have long been a major concern of the international community. However, no consensus has been reached hitherto. To explore and resolve the disagreements in the Himalayan study,in this paper we begin with the methodology and basic principles for the anatomy of composition and nature of convergent margins,then followed by an effort to conduct a similar anatomy for the India-Eurasia collision. One of the most common patterns of plate convergence involves a passive continental margin, an active continental margin and intra-oceanic basins together with accreted terranes in between. The ultimate configuration and location of the terminal suture zone are controlled by the basal surface of the accretionary wedge, which may show fairly complex morphology with Z-shape and fluctuant geometry. One plausible method to determine the terminal suture zone is to dissect the compositions and structures of active continental margins. It requires a focus on various tectonic elements belonging to the upper plate, such as accretionary wedges, high-pressure(HP)-ultra-high-pressure(UHP) metamorphic rocks, Barrovian-type metamorphic rocks and basement nappes, together with superimposed forearc basins.Such geological records can define the extreme limits and the intervening surface separating active margin from the passive one,thus offering a general sketch for the surface trace of the terminal suture zone often with a cryptic feature. Furthermore, the occurrence of the cryptic suture zone in depth may be constrained by geophysical data, which, in combination with outcrop studies of HP-UHP metamorphic rocks, enables us to outline the terminal suture zone. The southern part of the Himalayan orogen records complicated temporal and spatial features, which are hard to be fully explained by the classic 'two-plate-one-ocean' template,therefore re-anatomy of the compositions and nature for this region is necessitated. Taking advantage of the methodology and basic principles of plate convergence anatomy and synthesizing previous studies together with our recent research, we may gain new insights into the evolution of the Himalayan orogeny.(1) The Yarlung-Zangbo ophiolite is composed of multiple tectonic units rather than a single terminal suture zone, and a group of different tectonic units were juxtaposed against each other in the backstop of the Gangdese forearc.(2) The Tethyan Himalayan Sequence(THS) contains mélanges with typical block-in-matrix structures, uniform southwards paleocurrents and age spectra of detrital zircons typical of Eurasia continent. All of these facts indicate that the THS belonged to Eurasia plate before the terminal collision, emplaced in the forearc of the Gangdese arc.(3) The Greater Himalayan Crystalline Complex(GHC) and Lesser Himalayan Sequence(LHS) comprise complex components including eclogites emplaced into the GHC and the upper part of the LHS. Judging from the fact that HP-UHP metamorphic rocks are exhumed and emplaced in the upper plate, the GHC and the upper part of the LHS where eclogite occur should be assigned to the upper plate, lying above the terminal subduction zone surface. It is the very surface along which the continuous subduction of the India subcontinent occurred, therefore acting as the terminal, cryptic suture. From the suture further southward, the bulk rock associations of the LHS and Sub-Himalayan Sequence(Siwalik) show little affinity of mélange, probably belonging to the foreland system of the India plate. By the anatomy of tectonic features of all the tectonic units in the Himalayan orogen as well as the ages of the subduction-accretion related deformation, we conclude that the terminal India-Eurasia collision occurred after 14 Ma, the timing of the metamorphism of the eclogites emplaced into the upper plate. The development of rifts stretching in N-S direction in Tibet and tectonic events with the transition from sinistral to dextral movements in shear zones, such as the Ailaoshan fault in East Tibet, can coordinately reflect the scale and geodynamic influence of the India-Eurasia convergence zone.By conducting a detailed anatomy of the southern Himalayas, we propose a new model for the final collision-accretion of the Himalayan orogeny. Our study indicates that the anatomy of structures, composition, and tectonic nature is the key to a better understanding of orogenic belts, which may apply to all the orogenic belts around the world. We also point out that several important issues regarding the detailed anatomy of the structures, compositions and tectonic nature of the Himalayan orogeny in future.XIAO WenJiao AO SongJian YANG Lei HAN ChunMing WAN Bo ZHANG Ji'En ZHANG ZhiYong LI Rui CHEN ZhenYu SONG ShuaiHua 2017Science China Earth Sciences2017,60,6:20
10Dualistic water cycle pattern and its evolution in Haihe River basin显示文摘The Haihe River basin is widely recognized as an area in China which is most severely affected by human activities.The water resources utilization and recycling in the basin is very complex, and the characteristic of the dualistic water cycle is becoming more and more prominent.The ever-growing demand of water for modern industry and domestic life nearly dries up all the natu-ral runoff.Meanwhile, industrial, agricultural and domestic wastewater discharges cause severe deterioration in water quality.Consequently, many of water courses are either dried out or being heavily polluted.Modern water resources management can no longer rely on the 'monitoring-rehabilitation' model which was originally developed based on the natural water cycle.This paper analyzes the critical characteristics, water balance, and evolution of water flux process based on the theory of dualistic water cycle.Referring to the water cycle in the Haihe River basin, a schematic diagram was drawn to describe the dualistic water cycle pattern.Ten different parameters affecting mainly the evolution of water flux in the 'dualistic water cycle' are closely examined using the newly-collected data.As a result, this paper proposes several water management and control strategies to achieve healthy wa-ter status for the Haihe River basin.LIU JiaHong QIN DaYong WANG Hao WANG MingNa YANG ZhiYong 2010Chinese Science Bulletin2010,55,16:18
11Near-infrared responsive 5-fluorouracil and indocyanine green loaded MPEG-PCL nanoparticle integrated with dissolvable microneedle for skin cancer therapy显示文摘The prevalence of skin cancer is rising along with the rapid population aging in recent years.Traditional therapies,such as surgical treatment,radiotherapy,chemotherapy,photodynamic therapy,and immunotherapy,may accompany serious side effects,limiting their clinical benefits.According to the biological characteristics of skin cancer,we have already established two kinds of synergetic systems of photothermal therapy(microneedle)and chemotherapy,containing gold nanorods(GNR).Although the microneedle system exhibited great potential for skin cancer treatment,the system could be still improved further.So,we designed a near-infrared lightresponsive 5-fluorouracil(5-Fu)and indocyanine green(ICG)loaded monomethoxy-poly(ethylene glycol)-polycaprolactone(MPEG-PCL)nanoparticle(5-Fu-ICG-MPEG-PCL),and then 5-Fu-ICG-MPEG-PCL was integrated with a hyaluronic acid dissolvable microneedle system(HA MN)to get 5-Fu-ICG-MPEG-PCL loaded HA MN for treating skin cancers,including human epidermoid cancer and melanoma.In this system,hyaluronic acid,the microneedle carrier,possesses good skin penetration ability and is approved by FDA as a pharmaceutical adjuvant;5-Fu is recommended by FDA for skin cancer treatment;ICG,a photothermal agent,possesses a strong photothermal ability and is approved by FDA for its use in the human body.We hypothesized that 5-Fu-ICG-MPEG-PCL could be delivered by the dissolvable microneedle through the skin,and the release behavior of the drug in the nanoparticle could be controlled by near-infrared light for achieving a single-dose cure of skin cancer,improving the cure rate of skin cancer and providing a new idea and possibility for the clinical treatment of skin cancer.Ying Hao YuWen Chen XinLong He Fan Yang RuXia Han ChengLi Yang Wei Li ZhiYong Qian 2020Bioactive Materials2020,5,3:17
12‘Size effect’ related bending formability of thin-walled aluminum alloy tube显示文摘Aluminum alloy (Al-alloy) thin-walled (D/t > 20, diameter D, wall thickness t) bent tubes have attracted increasing applications in many industries with mass quantities and diverse specifications due to satisfying high strength to weigh ratio requirements of product manufacturing. However, due to nonlinear nature of bending with coupling effects of multiple factors, the similarity theory seems not applicable and there occurs a challenge for efficient and reliable evaluation of the bending formability of thin-walled tube with various bending specifications. Considering the unequal deformation and three major instabilities, the bending formability of thin-walled Al-alloy tube in changing tube sizes such as D and t are clarified via both the analytical and FE modeling/ simulations. The experiments of rotary draw bending are conducted to validate the theoretical models and further confirm 'size effect' related bending formability. The major results show that (1) The anti-wrinkling capability of tube decreases with the larger D and smaller t, and the effect significance of t is larger than that of D even under rigid supports; (2) The wall thinning increases with the larger D and smaller t, and this tendency becomes much more obvious under rigid supports; (3) The cross-section deformation increases with the larger D and smaller t according to the analytical model obtained intrinsic relationship, while this tendency becomes opposite due to the nonlinear role of mandrel die; (4) The size factor D/t can be used as a nondimensional index to evaluate both the bending formability regarding the wall thinning and cross-section deformation.Li Heng Yang He Zhang Zhiyong Wang Zekang 2013Chinese Journal of Aeronautics2013,26,1:16
13A structural view of the antibiotic degradation enzyme NDM-1 from a superbug显示文摘Gram-negative Enterobacteriaceae with resistance to carbapenem conferred by New Delhi metallo-β-lactamase 1(NDM-1)are a type of newly discovered antibioticresistant bacteria.The rapid pandemic spread of NDM-1 bacteria worldwide(spreading to India,Pakistan,Europe,America,and Chinese Taiwan)in less than 2 months characterizes these microbes as a potentially major global health problem.The drug resistance of NDM-1 bacteria is largely due to plasmids containing the blaNDM-1 gene shuttling through bacterial populations.The NDM-1 enzyme encoded by the blaNDM-1 gene hydrolyzes β-lactam antibiotics,allowing the bacteria to escape the action of antibiotics.Although the biological functions and structural features of NDM-1 have been proposed according to results from functional and structural investigation of its homologues,the precise molecular characteristics and mechanism of action of NDM-1 have not been clarified.Here,we report the threedimensional structure of NDM-1 with two catalytic zinc ions in its active site.Biological and mass spectroscopy results revealed that D-captopril can effectively inhibit the enzymatic activity of NDM-1 by binding to its active site with high binding affinity.The unique features concerning the primary sequence and structural conformation of the active site distinguish NDM-1 from other reported metallo-β-lactamases(MBLs)and implicate its role in wide spectrum drug resistance.We also discuss the molecular mechanism of NDM-1 action and its essential role in the pandemic of drug-resistant NDM-1 bacteria.Our results will provide helpful information for future drug discovery targeting drug resistance caused by NDM-1 and related metallo-β-lactamases.Yu Guo Jing Wang Guojun Niu Wenqing Shui Yuna Sun Honggang Zhou Yaozhou Zhang Cheng Yang Zhiyong Lou Zihe Rao 2011Protein & Cell2011,2,5:16

15Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation.Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu 2019Cancer Biology & Medicine2019,16,1:14
16Spinal Cord Stimulation for Pain Treatment After Spinal Cord Injury显示文摘In addition to restoration of bladder, bowel, and motor functions, alleviating the accompanying debilitating pain is equally important for improving the quality of life of patients with spinal cord injury(SCI). Currently,however, the treatment of chronic pain after SCI remains a largely unmet need. Electrical spinal cord stimulation(SCS) has been used to manage a variety of chronic pain conditions that are refractory to pharmacotherapy. Yet, its efficacy, benefit profiles, and mechanisms of action in SCI pain remain elusive, due to limited research, methodological weaknesses in previous clinical studies, and a lack of mechanistic exploration of SCS for SCI pain control. We aim to review recent studies and outline the therapeutic potential of different SCS paradigms for traumatic SCI pain. We begin with an overview of its manifestations,classification, potential underlying etiology, and currentchallenges for its treatment. The clinical evidence for using SCS in SCI pain is then reviewed. Finally, future perspectives of pre-clinical research and clinical study of SCS for SCI pain treatment are discussed.Qian Huang Wanru Duan Eellan Sivanesan Shuguang Liu Fei Yang Zhiyong Chen Neil C.Ford Xueming Chen Yun Guan 2019Neuroscience Bulletin2019,35,3:13
17Gold nanorods together with HSP inhibitor-VER-155008 micelles for colon cancer mild-temperature photothermal therapy显示文摘Enhancing the heat-sensitivity of tumor cells provides an alternative solution to maintaining the therapeutic outcome of photothermal therapy(PTT). In this study, we constructed a therapeutic system, which was composed of methoxy-polyethylene-glycol-coated-gold-nanorods(MPEG-AuN R) and VER-155008-micelles, to evaluate the effect of VER-155008 on the sensitivity of tumor cells to heat, and further investigate the therapeutic outcome of MPEG-AuN R mediated PTT combined with VER-155008-micelles. VER-155008-micelles downregulate the expression of heat shock proteins and attenuate the heat-resistance of tumor cell. The survival of HCT116 cells treated with VER-155008-micelles under 45 ℃ is equal to that treated with high temperature hyperthermia(55 ℃) in vitro. Furthermore, we proved either the MPEG-AuN R or VER-155008-micelles can be accumulate in the tumor site by photoacoustic imaging and fluorescent imaging. In vivo anti-cancer evaluation showed that tumor size remarkably decreased(smaller than 100 mm^3 or vanished) when treated with combing 45℃ mild PTT system, which contrasted to the tumor size when treated with individual 45℃ mild PTT(around 500nm^3) or normal saline as control(larger than 2000 nm^3). These results proved that the VER-155008-micelles can attenuate the heat-resistance of tumor cells and enhance the therapeutic outcome of mild-temperature photothermal therapy.Xichuan Tang Liwei Tan Kun Shi Jinrong Peng Yao Xiao Wenting Li Lijuan Chen Qian Yang Zhiyong Qian 2018Acta Pharmaceutica Sinica B2018,8,4:12
18Influence of refined hierarchical martensitic microstructures on yield strength and impact toughness of ultra-high strength stainless steel显示文摘The hierarchical martensitic features in ultra-high strength stainless steel(UHSSS),including the prior austenite grains,martensite packets,blocks and laths with the descending size,were refined to various extents by employing different thermomechanical processes and then carefully characterized.Their relation to yield strength and impact toughness was analyzed.We conclude that the refinement of martensitic structures could lead to the significant increase of yield strength,which follows the Hall-Petch relation with the effect grain size defined by high angle boundaries(HABs).Impact toughness of UHSSS depends on the frequency and capability for retained austenite(RA)grains at both HABs and martensite lath boundaries to trap the propagating cracks via strain-induced transformation,in which the film-like RA grains at lath boundaries appear to make the greater contribution.Haiwen Luo Xiaohui Wang Zhenbao Liu Zhiyong Yang 2020Journal of Materials Science & Technology2020,47,16:12
19Onset of Xiashu loess deposition in southern China by 0.9 Ma and its implications for regional aridification显示文摘The Xiashu loess is a typical Quaternary eolian deposit in southern China and represents an important terrestrial paleoclimate archive in this low-latitude monsoon region. However, the chronological framework of Xiashu loess deposition has yet to be established. Determining the timing of the onset of Xiashu loess deposition will allow researchers to better understand late Quaternary aridification across the Asian continent, the evolution of the East Asian monsoon and regional environmental changes in subtropical regions. Therefore, in this study, a systematic chronological study of the Xiashu loess is conducted to answer this question. For the first time, magnetostratigraphic classification reveals that the Matuyama/Brunhes(M/B) reversal is present in the Xiashu loess at two sites in Jiangsu Province, the Qingshan profile at Yizheng and the Dagang core in Zhenjiang.Based on the results of magnetostratigraphy and optically stimulated luminescence(OSL) dating, the age of the lower boundary of the Xiashu loess is estimated to be approximately 0.9 Ma. Consequently, this Xiashu loess deposit is the oldest reported to date and is comparable in age to the red soil deposit in Xuancheng, Anhui Province. The onset of Xiashu loess deposition by 0.9 Ma represents the further expansion of arid range in Asia in the late Quaternary in response to significant aridification and winter monsoon strengthening in this subtropical region. We suggest that these climate changes were primarily driven by global cooling and an increase in high-latitude ice volume in the Northern Hemisphere and that the initiation of Xiashu loess accumulation was a regional response of southern China to the 0.9 Ma global cooling event.Xusheng LI Zhiyong HAN Huayu LU Yingyong CHEN Yang LI Xiaokang YUAN Yuwen ZHOU Mengyao JIANG Cunjuan LV 2018Science China Earth Sciences2018,61,3:11
20Facile synthesis of ultrathin metal-organic framework nanosheets for Lewis acid catalysis显示文摘Ultrathin metalorganic framework (MOF) nanosheets are attracting great interest in catalysis due to their unique and intriguing two-dime nsional (2D) features. Although many progresses have been achieved, it is still highly desirable to develop novel strategies for controllable synthesis of the well-defined ultrathin MOF nanosheets. Herein we report a polyvinylpyrrolidone (PVP)-assisted route to synthesize the ultrathin Ni-MOF nanosheets characteristic of 1.5 nm in thickness, in which PVP is reacted with 2-aminoterephthalic acid (H2BDC-NH2) via formation of C=N bon d, followed by coord inatio n with Ni2+ io ns to form the ultrathi n MOF n anosheets. Impressively, when used in the Kno eve nagel condensation reactions of propane dinitrile with different aldehydes, ultrathin Ni-MOF nanosheets display the significantly enhanced catalytic activity and good stability in respect with the bulk Ni-MOF, mainly owing to the exposed active sites as well as facile mass transfer and diffusion of substrates and products.Xiaofei Zhang Lin Chang Zhongjie Yang Yanan Shi Chang Long Jianyu Han Binhao Zhang Xueying Qiu Guodong Li Zhiyong Tang 2019Nano Research2019,12,2:11
