| 1 | 42,573 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 | 2018 | Science China(Life Sciences)2018，61，6： | 39 |
| 2 | Craniocerebral injury promotes the repair of peripheral nerve injury显示文摘The increase in neurotrophic factors after craniocerebral injury has been shown to promote fracture healing. Moreover, neurotrophic factors play a key role in the regeneration and repair of peripheral nerve. However, whether craniocerebral injury alters the repair of peripheral nerve injuries remains poorly understood. Rat injury models were established by transecting the left sciatic nerve and using a free-fall device to induce craniocerebral injury. Compared with sciatic nerve injury alone after 6–12 weeks, rats with combined sciatic and craniocerebral injuries showed decreased sciatic functional index, increased recovery of gastrocnemius muscle wet weight, recovery of sciatic nerve ganglia and corresponding spinal cord segment neuron morphologies, and increased numbers of horseradish peroxidase-labeled cells. These results indicate that craniocerebral injury promotes the repair of peripheral nerve injury. | Wei Wang Jun Gao Lei Na Hongtao Jiang Jingfeng Xue Zhenjun Yang Pei Wang | 2014 | Neural Regeneration Research2014，9，18： | 15 |
| 3 | Enhanced mechanical properties and degradation rate of Mg-Ni-Y alloy by introducing LPSO phase for degradable fracturing ball applications显示文摘In this work,as-cast Mg-Ni-Y alloys were proposed to develop a feasible material for fracturing balls,and their mechanical performance and corrosion behavior were systematically investigated.Long period stacking order(LPSO)phase was firstly introduced to improve both the mechanical properties and degradation rate of magnesium alloys.With the increase of LPSO phase,the compressive strength was improved significantly,while the elongation of the alloys decreased owing to the relatively brittle nature of LPSO phase.Due to the higher corrosion potential of LPSO phase,the LPSO phase can accelerate the corrosion process by providing more micro-couples.However,the LPSO phase would serve as the corrosion barrier between the corrosion medium and the matrix when the contents of LPSO phase are too high in Mg92.5Ni3Y4.5 and Mg87.5Ni5Y7.5 alloys.As-cast Mg97.5Ni1Y1.5 alloy with satisfactory mechanical properties and rapid degradation rate was successfully developed,exhibiting a high degradation rate of 6675 mm/a(93℃)in 3 wt.%KCl solution and a favorable ultimate compressive strength of 410 MPa.The degradation rate of Mg97.5Ni1Y1.5 alloy is 2-5 times of the current commercial magnesium alloy fracturing materials. | Jingfeng Wang Shiqing Gao Xiuying Liu Xing Peng Kui Wang Shijie Liu Weiyan Jiang Shengfeng Guo Fusheng Pan | 2020 | Journal of Magnesium and Alloys2020，8，1： | 13 |
| 4 | Antioxidation Activities of Low-Molecular-Weight Gelatin Hydrolysate Isolated from the Sea Cucumber Stichopus japonicus显示文摘Gelatin extracted from the body wall of the sea cucumber (Stichopus japonicus) was hydrolyzed with flavourzyme.Low-molecular-weight gelatin hydrolysate (LMW-GH) of 700-1700 Da was produced using an ultrafiltration membrane bioreactor system.Chemiluminescence analysis revealed that LMW-GH scavenges high free radicals in a concentration-dependent manner;IC50 value for superoxide and hydroxyl radicals was 442 and 285 μg mL-1,respectively.LMW-GH exhibited excellent inhibitory characteristics against melanin synthesis and tyrosinase activity in B16 cells.Furthermore,LMW-GH notably increased intracellular glutathione (GSH),which in turn suppressed melanogenesis.LMW-GH performs antioxidation activity,holding the potential of being used as a valuable ingredient in function foods,cosmetics and pharmaceuticals or nutriceuticals. | WANG Jingfeng WANG Yuming TANG Qingjuan WANG Yi CHANG Yaoguang ZHAO Qin XUE Changhu | 2010 | Journal of Ocean University of China2010，9，1： | 13 |
| 5 | Test Data Generation for Stateful Network Protocol Fuzzing Using a Rule-Based State Machine显示文摘To improve the efficiency and coverage of stateful network protocol fuzzing, this paper proposes a new method, using a rule-based state machine and a stateful rule tree to guide the generation of fuzz testing data. The method first builds a rule-based state machine model as a formal description of the states of a network protocol.This removes safety paths, to cut down the scale of the state space. Then it uses a stateful rule tree to describe the relationship between states and messages, and then remove useless items from it. According to the message sequence obtained by the analysis of paths using the stateful rule tree and the protocol specification, an abstract data model of test case generation is defined. The fuzz testing data is produced by various generation algorithms through filling data in the fields of the data model. Using the rule-based state machine and the stateful rule tree,the quantity of test data can be reduced. Experimental results indicate that our method can discover the same vulnerabilities as traditional approaches, using less test data, while optimizing test data generation and improving test efficiency. | Rui Ma Daguang Wang Changzhen Hu Wendong Ji Jingfeng Xue | 2016 | Tsinghua Science and Technology2016，21，3： | 13 |
| 6 | Estimating biophysical parameters of rice with remote sensing data using support vector machines显示文摘Hyperspectral reflectance (350-2500 nm) measurements were made over two experimental rice fields containing two cultivars treated with three levels of nitrogen application.Four different transformations of the reflectance data were analyzed for their capability to predict rice biophysical parameters,comprising leaf area index (LAI;m-2 green leaf area m-2 soil) and green leaf chlorophyll density (GLCD;mg chlorophyll m 2 soil),using stepwise multiple regression (SMR) models and support vector machines (SVMs).Four transformations of the rice canopy data were made,comprising reflectances (R),first-order derivative reflectances (D1),second-order derivative reflectances (D2),and logarithm transformation of reflectances (LOG).The polynomial kernel (POLY) of the SVM using R was the best model to predict rice LAI,with a root mean square error (RMSE) of 1.0496 LAI units.The analysis of variance kernel of SVM using LOG was the best model to predict rice GLCD,with an RMSE of 523.0741 mg m-2.The SVM approach was not only superior to SMR models for predicting the rice biophysical parameters,but also provided a useful exploratory and predictive tool for analyzing different transformations of reflectance data. | YANG XiaoHua HUANG JingFeng WU YaoPing WANG JianWen WANG Pei WANG XiaoMing Alfredo R.

| 7 | 最大熵增地表蒸散模型:原理及应用综述显示文摘精确估算地表蒸散一直是地球系统科学中的难点问题。经典的蒸散模型大多建立在水汽输送及能量平衡约束等基础上,相关的基础理论研究进展缓慢。最大熵增地表蒸散(E-MEP)模型是在综合借鉴贝叶斯概率论、信息熵概念、非平衡态热力学理论和大气边界层湍流相似性理论的基础上,建立的全新地表蒸散理论框架,克服了经典模型的主要缺陷,包括:离散梯度模型不满足能量守恒条件,Penman模型针对饱和土壤,Penman-Monteith模型需要率定经验参数等。E-MEP模型具有3个显著特点:①同时给出地表(包括水面、雪面和冰面)蒸散量、感热通量和介质表面热通量,且在所有时间空间尺度上满足能量平衡方程;②模型公式中没有可调经验参数,不依赖于温度梯度和水汽梯度变量,不需要输入风速和表面粗糙度;③适用于任何土壤含水量和植被覆盖条件。由于E-MEP模型建立在坚实的数学物理基础上,并具有解析表达式,简单易用,其输入变量和模型参数少于传统蒸散模型使用。地表辐射、表面温度、表面比湿等模型输入变量易于实地观测获取,且可通过遥感反演获得。检验分析表明,E-MEP模型优于Penman和Penman-Monteith等传统蒸散模型。这一全新的地表蒸散模型已被用于大尺度地表水热的遥感反演和过程监测,并用于改进气候模式的参数化方案。 | Wang Jingfeng 刘元波 张珂 | 2019 | 地球科学进展2019，34，6： | 11 |
| 8 | Effect of Cyclocarya paliurus polysaccharides on streptozotocin-induced diabetic nephropathy in rats显示文摘OBJEVTIVE:To investigate the efficacy of Cyclocarya paliurus(C.paliurus)polysaccharides on streptozotocin-induced diabetic nephropathy in rats.METHODS:Rats were divided into 6 groups,including group of normal control,group of diabetic control,group of metformin treatment,low-dose group of C.paliurus polysaccharides treatment,middle-dose group of C.paliurus polysaccharides treatment and high-dose group of C.paliurus polysaccharides treatment.Histological analysis of kidney was analyzed using hematoxilin and eosin.Levels of blood glucose,creatinine,urea,uric acid were determined by spectrophotometry.Anti-oxidative enzymes were measured by real-time polymerase chain reaction(PCR)and enzyme-linked immunosorbent assay(ELISA).Advanced glycation end products(AGEs)and transforming growth factor-β1(TGF-β1)level was measured by ELISA.RESULTS:Abnormal changes were observed in the group of diabetic control characterized by atrophy of the renal glomeruli with hypercellularity,congestion of glomerular tufts,dilation of the renal spaces,and degeneration of renal tubule.Compared with that of normal group,blood glucose,creatinine,urea,uric acid level was significantly increased in the group of diabetic control.Superoxide dismutase,catalase,glutathione peroxidase,glutathione reductase level was significantly decreased,but AGEs and TGF-β1 level was significantly increased.By contrast,administration of C.paliurus polysaccharides and metformin could reverse the above-mentioned results of the group of diabetic control,especially in the high-dose group of C.paliurus polysaccharides.CONCLUSION:Our findings suggest that C.paliurus polysaccharides may play a protecting role for nephropathy of diabetic rats by lowering glucose,creatinine,urea,uric acid level,enhancing the antioxidative ability,and reducing AGEs and TGF-β1 expression. | Xia Xichao Mao Dongxue Dai Hongmei Wu Xi Zhang Zuyuan Wang Huaying Zhou Wenwen Dong Yanmei Wang Mengqi Li Yuan Shao Xiangyang Ouyang Jingfeng | 2020 | Journal of Traditional Chinese Medicine2020，40，6： | 9 |
| 9 | Kinetics of the hydrogen absorption and desorption processes of hydrogen storage alloys: A review显示文摘High hydrogen absorption and desorption rates are two significant index parameters for the applications of hydrogen storage tanks.The analysis of the hydrogen absorption and desorption behavior using the isothermal kinetic models is an efficient way to investigate the kinetic mechanism.Multitudinous kinetic models have been developed to describe the kinetic process.However,these kinetic models were de-duced based on some assumptions and only appropriate for specific kinetic measurement methods and rate-controlling steps(RCSs),which sometimes lead to confusion during application.The kinetic analysis procedures using these kinetic models,as well as the key kinetic parameters,are unclear for many researchers who are unfamiliar with this field.These problems will prevent the kinetic models and their analysis methods from revealing the kinetic mechanism of hydrogen storage alloys.Thus,this review mainly focuses on the summarization of kinetic models based on different kinetic measurement methods and RCSs for the chemisorption,surface penetration,diffusion of hydrogen,nucleation and growth,and chemical reaction processes.The analysis procedures of kinetic experimental data are expounded,as well as the effects of temperature,hydrogen pressure,and particle radius.The applications of the kinetic models for different hydrogen storage alloys are also introduced. | Qian Li Xi Lin Qun Luo Yuʼan Chen Jingfeng Wang Bin Jiang Fusheng Pan | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 9 |
| 10 | Effects of Y on the Microstructure, Mechanical and Bio-corrosion Properties of Mg-Zn-Ca Bulk Metallic Glass显示文摘The micro-alloying effects of Y on the microstructure, mechanical properties, and bio-corrosion behavior of Mg69-xZn27Ca4Yx(x= 0, 1, 2 at.%) alloys were investigated through X-ray diffraction, compressive tests,electrochemical treatments, and immersion tests. The Mg69Zn27Ca4 alloy was found to be absolutely amorphous, and its glass-forming ability decreased with the addition of Y. The Mg68Zn27Ca4Y1 alloy exhibited an ultrahigh compressive strength above 1010 MPa as well as high capacity for plastic strain above 3.1%.Electrochemical and immersion tests revealed that these Y-doped MgeZ neC a alloys had good bio-corrosion resistance in simulated body fluid(SBF) at 37℃. The results of the cytotoxicity test showed high cell viabilities for these alloys, which means good bio-compatibility. | Jingfeng Wang Yang Li Song Huang Yiyun Wei Xingfeng Xi Kaiyong Cai Fusheng Pan | 2014 | Journal of Materials Science & Technology2014，30，12： | 8 |

| 12 | Micro-arc oxidation of magnesium alloys:A review显示文摘Magnesium(Mg)and its alloys present great potential to be extensively applied in different applications.However,the relatively poor resistance to corrosion and wear significantly restricts their applications in practice.As one of strategies of surface treatment,micro-arc oxidation(MAO)process attracts a lot of attention,since it does not use neither expensive equipment,nor complicated manipulation.This review systematically discusses MAO mechanism and some typical models,which still need to be further developed to provide a better understanding and guide for future researchers.Subsequently,main influencing factors of MAO process are analyzed in detail.Further,some popular applications of MAO coatings are respectively reviewed,including biomedical application,decoration,thermal control,corrosion and wear resistance,and industrial applications in practice.The existing issues and future perspectives are finally discussed to further accelerate extensive applications of Mg alloys. | Wenhui Yao Liang Wu Jingfeng Wang Bin Jiang Dingfei Zhang Maria Serdechnova Tatsiana Shulha Carsten Blawert Mikhail L.Zheludkevich Fusheng Pan | 2022 | Journal of Materials Science & Technology2022，，23： | 8 |
| 13 | Effect of Sn addition on the mechanical properties and bio-corrosion behavior of cytocompatible Mg-4Zn based alloys显示文摘The mechanical properties and bio-corrosion behaviors of as-extruded Mg-4Zn alloys after Sn addition were investigated,systemati-cally.A small amount of Sn addition to Mg-4Zn alloy slightly improved the mechanical properties for solid solution strengthening,and significantly controlled the bio-corrosion rates.Sn participating in the outer layer film formation as SnO/SnO_(2)resisted the bio-corrosion proceeding.Especially,Mg-4Zn-1.5Sn alloy,with a weight loss rate of 0.45 mm/y and hydrogen evolution rate of 0.099 mL/cm^(2)/day,showed cytotoxicity grade of 0 to MC3T3-E1 cells.The perfect alliance of cytocompatibility,suitable mechanical properties and low bio-corrosion rate demonstrates that this Mg-4Zn-1.5Sn alloy is a promising biodegradable magnesium alloy for orthopedic implants. | Weiyan Jiang Jingfeng Wang Weikang Zhao Qingshan Liu Dianming Jiang Shengfeng Guo | 2019 | Journal of Magnesium and Alloys2019，7，1： | 6 |
| 14 | Processes of coastal ecosystem carbon sequestration and approaches for increasing carbon sink显示文摘The oceans are the largest carbon pools on Earth, and play the role of a 'buffer' in climate change. Blue carbon, the carbon(mainly organic carbon) captured by marine ecosystems, is one of the important mechanisms of marine carbon storage.Blue carbon was initially recognized only in the form of visible coastal plant carbon sequestration. In fact, microorganisms(phytoplankton, bacteria, archaea, viruses, and protozoa), which did not receive much attention in the past, account for more than 90% of the total marine biomass and are the main contributors to blue carbon. Chinese coastal seas, equivalent to 1/3 of China's total land area, have a huge carbon sink potential needing urgently research and development. In this paper, we focus on the processes and mechanisms of coastal ocean's carbon sequestration and the approaches for increasing that sequestration. We discuss the structures of coastal ecosystems, the processes of carbon cycle, and the mechanisms of carbon sequestration. Using the evolution of coastal ocean's carbon sinks in sedimentary records over geologic times, we also discuss the possible effects of natural processes and anthropogenic activities on marine carbon sinks. Finally, we discuss the prospect of using carbon sequestration engineering for increasing coastal ocean's carbon storage capacity. | ZHANG Yao ZHAO MeiXun CUI Qiu FAN Wei QI JiaGuo CHEN Ying ZHANG YongYu GAO KunShan FAN JingFeng WANG GuangYi YAN ChongLing LU HaoLiang LUO YaWei ZHANG ZiLian ZHENG Qiang XIAO Wei JIAO NianZhi | 2017 | Science China Earth Sciences2017，60，5： | 6 |
| 15 | Experiment and simulation on the pyrite removal from the recirculating load of pulverizer with a dilute phase gas-solid fluidized bed显示文摘In order to reduce the energy consumption and subsequent air pollution of coal-fired power station, based on the analysis to size and density distribution of particles from the recirculating load of the classifier of pulverizer, the separation experiment on sampling material from power plant with a dilute phase fluidized bed to remove pyrite and other minerals and numerical simulation on the separation process were done. The results show that the minimum fluidization velocity is 1.62 cm/s. Pyrite and other minerals in the material are separated. Ash of the upper and bottom layer material account for 33.34% and 73.42% respectively and sulfur content occupy 1.12% and 8.96% respectively. Scanning electron microscopy and spectroscopy tests show that sulfur in the bottom material exist in the form of pyrite. Numerical simulation on the flow field form of the dilute phase separation bed with gas-solid two phase and particle motion verifies the experimental results. | Wang Shuai He Yaqun He Jingfeng Ge Linhan Liu Qing | 2013 | International Journal of Mining Science and Technology2013，23，2： | 6 |
| 16 | The temporal and spatial fluctuation of the groundwater level along the Tarim Desert Highway显示文摘In this work, a groundwater monitor section along the Tarim Desert Highway was set up, and the groundwater level data were recorded. The temporal and spatial fluctuations of the groundwater level were analyzed based on the groundwater level measurements, hydrologic data, the groundwater/surface water interconversion theory and the groundwater dynamics. The spatial distribution of groundwater is mostly affected by sand dune height and landform variation. The four primary temporal influence factors of groundwater level can be ordered in decreasing significance as: shelterbelt pumping > vertical leakage > river flow change > runoff replenishment. The runoff replenishment has the biggest influence range, and the shelterbelt pumping has the smallest influence range. The groundwater level fluctuates annually in a natural pattern. | FAN JingLong XU XinWen LEI JaQiang ZHAO JingFeng LI ShengYu WANG HaiFeng ZHANG JianGuo ZHOU HongWei | 2008 | Chinese Science Bulletin2008，53，S2： | 6 |
| 17 | An improved neural network model for prediction of mechanical properties of magnesium alloys显示文摘An improved neural network model was developed for prediction of mechanical properties in the de-sign and development of new types of magnesium alloys by refining the types of input variables and using a more reasonable algorithm. The results showed that the improved model apparently decreased the prediction errors, and raised the accuracy of the prediction results. Better preprocessing parame-ters were found to be [0.15, 0.90] for the tensile strength, [0.1, 0.9] for the yield strength, and [0.15, 0.90] for the elongation. When the above parameters were used, the relativity for predicition of strength was bigger than 0.95. By using improved ANN analysis, more reasonable process parameters and compo- sition could be obtained in some magnesium alloys without addition of strontoum. | TANG AiTao LIU Bin PAN FuSheng ZHANG Jing PENG Jian WANG JingFeng | 2009 | Science China(Technological Sciences)2009，52，1： | 5 |
| 18 | Strain hardening of as-extruded Mg-xZn(x=1, 2, 3 and 4 wt%) alloys显示文摘The influence of Zn on the strain hardening of as-extruded Mg-x Zn(x = 1, 2, 3 and 4 wt%) magnesium alloys was investigated using uniaxial tensile tests at 10^(-3)s^(-1) at room temperature. The strain hardening rate,the strain hardening exponent and the hardening capacity were obtained from true plastic stress-strain curves. There were almost no second phases in the as-extruded Mg-Zn magnesium alloys. Average grain sizes of the four as-extruded alloys were about 17.8 μm. With increasing Zn content from 1 to 4 wt%, the strain hardening rate increased from 2850 MPa to 6810 MPa at(б-б_(0.2)) = 60 MPa, the strain hardening exponent n increased from 0.160 to 0.203, and the hardening capacity, Hc increased from 1.17 to 2.34.The difference in strain hardening response of these Mg-Zn alloys might be mainly caused by weaker basal texture and more solute atoms in the α-Mg matrix with higher Zn content. | Chaoyue Zhao Xianhua Chen Fusheng Pan Jingfeng Wang Shangyu Gao Teng Tu Chunquan Liu Jiahao Yao Andrej Atrens | 2019 | Journal of Materials Science & Technology2019，35，1： | 4 |

| 20 | Effect of Ni on the microstructure, mechanical properties and corrosion behavior of MgGd_1Ni_(x) alloys for fracturing ball applications显示文摘The effects of Ni addition on the mechanical properties, corrosion behaviors, and corrosion mechanism of Mg Gd_1 Ni_(x) alloys have been investigated by compressive tests, weight loss, hydrogen evolution, and scanning electron microscopy. The results show that the constitution of the second phase is large dependence on Ni/Gd molar ratios, which can transform from LPSO(long-period stacking ordered)+Mg_5 Gd,LPSO to eutectic phase. In addition, with increasing Ni/Gd molar ratios, the content of second phase increases gradually, while the LPSO phase shows a parabola relationship. Furthermore, the formation of Nicontaining LPSO phase not only can improve the strength but also accelerate the degradation of Mg alloys owing to the galvanic corrosion. The optimal properties with ultimate compressive strength, degradation rate are 340 MPa, 2066 mm/y for Mg Gd1 Ni0.75, respectively, which can meet the engineering application standard of fracturing ball and can be used as candidate materials for fracturing ball. | Kai Ma Shijie Liu Chaoneng Dai Xiuying Liu Jie Ren Yuanlang Pan Yinhong Peng Chen Su Jingfeng Wang Fusheng Pan | 2021 | Journal of Materials Science & Technology2021，，32： | 4 |
