142,573 cases of hepatectomy in China: a multicenter retrospective investigation显示文摘Hepatectomy is currently routinely performed in most hospitals in China. China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma(HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients,81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein(AFP) level, and other 35% had an AFP level lower than 400 ng mL^(-1). In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was(191.7±105.6) min,the blood loss was(546.0±562.8) m L, and blood transfusion was(543.0±1,035.2) m L. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules,tumor thrombosis and high AFP level were risk factors that affect postoperative survival.Binhao Zhang Bixiang Zhang Zhiwei Zhang Zhiyong Huang Yifa Chen Minshan Chen Ping Bie Baogang Peng Liqun Wu Zhiming Wang Bo Li Jia Fan Lunxiu Qin Ping Chen Jingfeng Liu Zhe Tang Jun Niu Xinmin Yin Deyu Li Songqing He Bin Jiang Yilei Mao Weiping Zhou Xiaoping Chen 2018Science China(Life Sciences)2018,61,6:39

4WRF/CHEM modeling of impacts of weather conditions modified by urban expansion on secondary organic aerosol formation over Pearl River Delta显示文摘In this paper,the online Weather Research and Forecasting and Chemistry (WRF/CHEM) model,coupled with urban canopy (UCM) and biogenic-emission models,is used to explore impacts of urban expansion on secondary organic aerosols (SOA) formation. Two scenarios of urban maps are used in WRF/CHEM to represent early 1990s (pre-urbanization) and current urban distribution in the Pearl River Delta (PRD). Month-long simulation results using the above land-use scenarios for March 2001 show:(1) urbanization can increase monthly averaged temperatures by about 0.63 ?C,decrease monthly averaged 10-m wind speeds by 38%,increase monthly averaged boundary-layer depths by 80 m,and decrease monthly aver-aged water mixing ratio by 0.2 g/kg. (2) Changes in meteorological conditions can result in detectable concentration changes of NOx,VOC,O3 and NO3 radicals. Urbanization decreases surface NOx and VOC concentrations by a maximum of 4 ppbv and 1.5 ppbv,respectively. Surface O3 and NO3 radical concen-trations over major cities increase by about 2-4 ppbv and 4-12 pptv,respectively; areas with increasing O3 and NO3 radical concentrations generally coincide with the areas of temperature increase and wind speed reduction where NOx and VOC decrease. (3) Urbanization can induce 9% increase of SOA in Foshan,Zhongshan and west Guangzhou and 3% decrease in Shenzhen and Dongguan. Over PRD major cities,SOA from Aitken mode reduces by 30% but with more than 70% SOA from accumulate mode. Urbanization has stronger influence on SOA formation from Aitken mode. (4) Over the PRD,55-65% SOA comes from aromatics precursors. Urbanization has strongest influence on aromatics precursors to produce SOA (14% increase),while there is less influence on alkane precursors. Alkene precursors have negative contribution to SOA formation under urbanization situation.Xuemei Wang Zhiyong Wu Guixiong Liang 2009Particuology2009,7,5:25
5Clinical effects of innovative tuina manipulations on treating cervical spondylosis of vertebral artery type and changes in cerebral blood flow显示文摘OBJECTIVE:To determine the clinical effect,treatment times,and rheoencephalogram changes in vertebral artery type cervical spondylosis patients treated with innovative Tuina manipulations.METHODS:One hundred and twenty six cervical spondylosis patients(vertebral artery type) were randomly divided into test and control groups.Patients in the test group were treated with innovative Tuina manipulations,while those in the control group were treated with the routine Tuina manipulations according to the textbook of Chinese Massage for Acupuncture and Moxibustion majors.The clinical effects,treatment times,clinical symptoms,and cerebral blood flow were measured.RESULTS:The response to the treatment was 100% in the test group and 88.71% in the control group.Patients in the test group required(7 ± 4) treatments before recovery,while those in the control group required(15 ± 7) treatments before recovery(P<0.05).The clinical symptoms exhibited greater improvement in the test group compared to the control group(P<0.05).There were no differences in cerebral blood flow between the two groups.CONCLUSION:Both innovative Tuina manipulations and routine Tuina manipulations produced satisfactory therapeutic results in vertebral artery type cervical spondylosis patients.However,the innovative manipulation was more effective in improving the functional symptoms,although there were no changes in the cerebral blood flow.Quanmao Ding Mingru Yan Ji Zhou Lu Yang Jiang Guo Jun Wang Zhiyong Shi Yixi Wang Hongsheng Zhao 2012Journal of Traditional Chinese Medicine2012,32,3:24

7Dualistic 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
8Natural Variation in CCD4 Promoter Underpins Species-Specific Evolution of Red Coloration in Citrus Peel显示文摘Carotenoids and apocarotenoids act as phytohormones and volatile precursors that influence plant development and confer aesthetic and nutritional value critical to consumer preference.Citrus fruits display considerable natural variation in carotenoid and apocarotenoid pigments.In this study,using an integrated genetic approach we revealed that a 5;c/s-regulatory change at CCD4b encoding CAROTENOID CLEAVAGE DIOXYGENASE 4b is a major genetic determinant of natural variation in C3 0 apocarotenoids responsible for red coloration of citrus peel.Functional analyses demonstrated that in addition the known role in synthesizing 3-citraurin,CCD4b is also responsible for the production of another important C3 0 apocarotenoid pigment,p-citraurinene.Furthermore,analyses of the CCD4b promoter and transcripts from various citrus germplasm accessions established a tight correlation between the presence of a putative 5'c/s-regulatory enhancer within an MITE transposon and the enhanced allelic expression of CCD4b in C3 0 apocarotenoid-rich red-peeled accessions.Phylogenetic analysis provided further evidence that functional diversification of CCD4b and naturally occurring variation of the CCD4b promoter resulted in the stepwise evolution of red peels in mandarins and their hybrids.Taken together,our findings provide new insights into the genetic and evolutionary basis of apocarotenoid diversity in plants,and would facilitate breeding efforts that aim to improve the nutritional and aesthetic value of citrus and perhaps other fruit crops.Xiongjie Zheng Kaijie Zhu Quan Sun Weiyi Zhang Xia Wang Hongbo Cao Meilian Tan Zongzhou Xie Yunliu Zeng Junli Ye Lijun Chai Qiang Xu Zhiyong Pan Shunyuan Xiao Paul D.Fraser Xiuxin Deng 2019Molecular Plant2019,12,9:18
9A structural view of the conserved domain of rice stress-responsive NAC1显示文摘The importance of NAC(named as NAM,ATAF1,2,and CUC2)proteins in plant development,transcription regulation and regulatory pathways involving proteinprotein interactions has been increasingly recognized.We report here the high resolution crystal structure of SNAC1(stress-responsive NAC)NAC domain at 2.5Å.Although the structure of the SNAC1 NAC domain shares a structural similarity with the reported structure of the ANAC NAC1 domain,some key features,especially relating to two loop regions which potentially take the responsibility for DNA-binding,distinguish the SNAC1 NAC domain from other reported NAC structures.Moreover,the dimerization of the SNAC1 NAC domain is demonstrated by both soluble and crystalline conditions,suggesting this dimeric state should be conserved in this type of NAC family.Additionally,we discuss the possible NAC-DNA binding model according to the structure and reported biological evidences.Qingfeng Chen Quan Wang Lizhong Xiong Zhiyong Lou 2011Protein & Cell2011,2,1:18
10Isolation of osRACD gene encoding a small GTP-binding protein from rice显示文摘Using an improved version of mRNA differential display technology, we have obtained a differentially displayed fragment RDP-8. Homologous comparison indicated that the fragment RDP-8 has high homology with the gene encoding maize small GTP-binding protein. By screening cDNA library of the rice Nongken 58N panicle using the newly obtained fragment RDP-8 as probe, we further found the full-length cDNA of osRACD gene that encodes a rice small GTP-binding protein. As compared with maize RACD gene, the osRACD of rice shows remarkable homology in both nucleotide sequence and amino acid sequence, 88% and 97% respectively. Evidence from RT-PCR study indicates that osRACD gene is related to photoperiod fertility conversion of photoperiod sensitive genie male sterility (PSGMS) rice.Ml Zhiyong WANG Shusheng WU Naihu 2002Chinese Science Bulletin2002,47,20:17
11‘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
12A 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
13USP19 suppresses inflammation and promotes M2-like macrophage polarization by manipulating NLRP3 function via autophagy显示文摘Macrophage polarization to proinflammatory M1-like or anti-inflammatory M2-like cells is critical to mount a host defense or repair tissue.The exact molecular mechanisms controlling this process are still elusive.Here,we report that ubiquitin-specific protease 19(USP19)acts as an anti-inflammatory switch that inhibits inflammatory responses and promotes M2-like macrophage polarization.USP19 inhibited NLRP3 inflammasome activation by increasing autophagy flux and decreasing the generation of mitochondrial reactive oxygen species.In addition,USP19 inhibited the proteasomal degradation of inflammasome-independent NLRP3 by cleaving its polyubiquitin chains.USP19-stabilized NLRP3 promoted M2-like macrophage polarization by direct association with interferon regulatory factor 4,thereby preventing its p62-mediated selective autophagic degradation.Consistent with these observations,compared to wild-type mice,Usp19−/−mice had decreased M2-like macrophage polarization and increased interleukin-1βsecretion,in response to alum and chitin injections.Thus,we have uncovered an unexpected mechanism by which USP19 switches the proinflammatory function of NLRP3 into an anti-inflammatory function,and suggest that USP19 is a potential therapeutic target for inflammatory interventions.Tao Liu Liqiu Wang Puping Liang Xiaojuan Wang Yukun Liu Jing Cai Yuanchu She Dan Wang Zhi Wang Zhiyong Guo Samuel Bates Xiaojun Xia Junjiu Huang Jun Cui 2021Cellular & Molecular Immunology2021,18,10:15
14Magnolol additive as a replacer of antibiotic enhances the growth performance of Linwu ducks显示文摘Magnolol rich in Magnolia officinalis is a bioactive polyphenolic compound. The aim of this study was to examine the effects of magnolol additive(MA) on growth performance, expression levels of antioxidantrelated genes, and intestinal mucosal morphology of Linwu ducks aged from 49 to 70 days, comparing with that of an antibiotic additive(colistin sulfate [CS]). A total of 275,49-day-old ducks were assigned to5 groups with 5 cages of 11 ducks each and fed diets supplemented with 0,100, 200 and 300 mg of MA/kg and 300 mg of CS/kg for 3 weeks, respectively. The results showed that the average daily body weight gain(ADG) was increased significantly in MA-fed groups(200 and 300 mg/kg), compared with the basal diet(BD) group(P < 0.05). The mRNA levels of superoxide dismutase-1(SOD1), manganese superoxide dismutase-2(MnSOD2) and catalase(CAT) were also increased significantly in MA groups(P < 0.05). In addition, hematoxylin and eosin staining revealed that Linwu ducks fed the diets with MA had more intact intestinal mucosa than those fed the BD and CS diets. In addition, ileal villus height, ileal villus height/crypt depth ratio(V/C) and duodenal V/C were also improved significantly(P < 0.05). Taken together, these data demonstrated that MA is an effective feed additive to enhance the growth performance of the Linwu ducks by improving the antioxidant and intestinal mucosal status, suggesting that MA will be a potential additive to replace antibiotic(CS).Qian Lin Jianfei Zhao Kun Xie Yushi Wang Guili Hu Guitao Jiang Qiuzhong Dai Zhiyong Fan Jianhua He Xi He De-Xing Hou 2017Animal Nutrition2017,,2:14
15Geologic characteristics of the Chang'E-3 exploration region显示文摘We present topographic,geomorphologic and compositional characteristics of a 1°×1°(~660 km2)region centered near the landing site of Chang’E-3 using the highest spatial resolution data available.We analyze the topography and slope using Digital Terrain Model(DTM)generated from Terrain Camera(TC)images.The exploration region is overall relatively flat and the elevation difference is less than 300 m,and the slopes of 80%area are less than 5°.Impact craters in the exploration region are classified into four types based on their degradation states.We investigate the wrinkle ridges visible in the exploration region in detail using TC and Lunar Reconnaissance Orbiter(LRO)Narrow Angle Camera(NAC)images.We calculate FeO and TiO2 abundances using Multispectral Imager(MI)data,and confirm two basaltic units:the northern part belongs to Imbrian low-Ti/very-low-Ti mare basalts,and the southern part is Eratosthenian low-Ti/high-Ti mare basalts.Finally,we produce a geological map and propose the geologic evolution of the exploration region.We also suggest several rover traverses to explore interesting targets and maximize the potential scientific output.ZHAO JianNan HUANG Jun QIAO Le XIAO ZhiYong HUANG Qian WANG Jiang HE Qi XIAO Long 2014Science China(Physics,Mechanics & Astronomy)2014,57,3:14

17The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence.Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li 2023Science China(Physics,Mechanics & Astronomy)2023,66,8:14

19Selective separation of protein and saccharides by ionic liquids aqueous two-phase systems显示文摘In the present work,it was found that aqueous solution of a hydrophilic ionic liquid (IL),1-butyl-3-methylimidazolium dicyanamide ([C4mim][N(CN)2]),could be separated into an aqueous two-phase system (ATPS) by inorganic salts such as K2HPO4 and K3PO4.The top phase is IL-rich,while the bottom phase is phosphate-rich.It was shown that 82.7%-100% bovine serum albumin (BSA) could be enriched into the top phase and almost quantitative saccharides (arabinose,glucose,sucrose,raffinose or dextran) were preferentially extracted into the bottom phase in a single-step extraction by [C4mim][N(CN)2] + K2HPO4 ATPS.The extraction efficiency of BSA from the aqueous saccharide solutions was influenced by the molecular structure of saccharides.The conductivity,dynamic light scattering (DLS) and transmission electron microscopy (TEM) were combined to investigate the microstructure of the IL-rich top phase and the possible mechanism for the selective separation.It is suggested that the formation of the IL aggregate and the IL aggregate-BSA complex plays a significant role in the separation of BSA from aqueous saccharide solutions.This is the first example for the selective separation by ILs-based ATPSs.It is expected that these findings would have potential applications in bio-analysis,separation,and IL recycle.PEI YuanChao LI ZhiYong LIU Li WANG JianJi WANG HuiYong 2010Science China Chemistry2010,53,7:12
20Influence 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
