| 1 | Seafloor hydrothermal activity and polymetallic sulfide exploration on the southwest Indian ridge显示文摘Polymetallic sulfides have attracted more attentions,which are regarded as one of the potential seabed mineral resources for their high grade of precious metal elements such as Cu,Zn,Pb,Au,and Ag.Since2007,there are four China dayang cruises(CDCs)with eight legs totally,which have been carried out to investigate polymetallic sulfides on the southwest Indian ridge(SWIR),and eight hydrothermal vents have been found.In2011,the China Ocean Mineral Resources Research and Development Association(COMRA)and International Seabed Authority(ISA)signed a 15-year contract for exploration for polymetallic sulfides located on the SWIR between 46°S and 53°S.The area allocated to the COMRA is approximately 10,000 km2.In this paper,we review the recent research advances about hydrothermal activity of the SWIR by the CDCs.As for the sulfides exploration in the future,some aspects should be emphasized,such as the controlling factors of sulfide mineralization on the SWIR,prospecting methods of inactive and buried sulfide deposits,sulfides resources assessment method,and the nearbottom sulfides exploration technology systems. | Chunhui Tao Huaiming Li Xiaobing Jin Jianping Zhou Tao Wu Yonghua He Xianming Deng Chunhua Gu Guoyin Zhang Weiyong Liu | 2014 | Chinese Science Bulletin2014，59，19： | 25 |
| 2 | Substance P-modified human serum albumin nanoparticles loaded with paclitaxel for targeted therapy of glioma显示文摘The blood–brain barrier(BBB) and the poor ability of many drugs to cross that barrier greatly limits the efficacy of chemotherapies for glioblastoma multiforme(GBM). The present study exploits albumin as drug delivery vehicle to promote the chemotherapeutic efficacy of paclitaxel(PTX) by improving the stability and targeting efficiency of PTX/albumin nanoparticles(NPs). Here we characterize PTX-loaded human serum albumin(HSA) NPs stabilized with intramolecular disulfide bonds and modified with substance P(SP) peptide as the targeting ligand. The fabricated SP-HSA-PTX NPs exhibited satisfactory drug-loading content(7.89%) and entrapment efficiency(85.7%) with a spherical structure(about 150 nm) and zeta potential of -12.0 mV. The in vitro drug release from SP-HSA-PTX NPs occurred in a redox-responsive manner. Due to the targeting effect of the SP peptide, cellular uptake of SP-HSA-PTX NPs into brain capillary endothelial cells(BCECs) and U87 cells was greatly improved.The low IC_(50), prolonged survival period and the obvious pro-apoptotic effect shown by TUNEL analysis all demonstrated that the fabricated SP-HSA-PTX NPs showed a satisfactory anti-tumor effect and could serve as a novel strategy for GBM treatment. | Chunhui Ruan Lisha Liu Yifei Lu Yu Zhang Xi He Xinli Chen Yujie Zhang Qinjun Chen Qin Guo Tao Sun Chen Jiang | 2018 | Acta Pharmaceutica Sinica B2018，8，1： | 19 |
| 3 | Effects of melatonin implantation on cashmere yield,fibre characteristics,duration of cashmere growth as well as growth and reproductive performance of Inner Mongolian cashmere goats显示文摘Background:Exogenous melatonin could induce cashmere growth.However,induced growth of cashmere fleece by melatonin implants cannot be combined with the typical growth,resulting in earlier shedding followed by another cycle of cashmere growth.To address this issue,we examine the effects on the cashmere yield,fibre characteristics,and the growth and reproductive performance of cashmere goats of planned administration of melatonin.Methods:Eighteen half-sib,female goats were assigned to two treatments(n = 9) including a control and a treatment where melatonin(2 mg/kg BW) was implanted at the end of April and end of June.Cashmere growth and shedding were observed for approximately 1 year following implantation.Fibre samples were collected monthly to determine cumulative cashmere length.Initiation and cessation dates for cashmere growth as well as the rate of cashmere growth were calculated.Cashmere yield,weight gain of dam,kidding date,litter size,and birth weight were also recorded.Results:Melatonin implantation increased cashmere yield by 34.5%(control 553.7 g vs.melatonin 745.0 g;P< 0.01),cashmere length by 21.3%(control 95.2 mm vs.melatonin 115.4 mm;P < 0.01),and decreased fibre diameter by 4.4%(control 14.6 μm vs.melatonin 14.0 μm;P < 0.03).In melatonin-treated goats,the average initiation date was earlier than in control goats(May 18,2013 vs.July 2,2013;P< 0.01) but there was a similar cessation date(March 22,2014 vs.March 27,2014).Consequently,the duration of cashmere growth was longer in melatonin-treated goats than in control goats(307 vs.270 days;P< 0.01).The final BW,average daily gain,kidding date,litter size,and birth weight were not influenced by melatonin implantation.Conclusions:These data indicate that melatonin implantation(2 mg/kg BW) on two occasions(late April and June)increased cashmere yield by combining the induced growth of cashmere fleece with the typical growth and decreased the fibre diameter without changing dam growth rate or reproductive performance. | Chunhui Duan Jianhai Xu Changmian Sun Zhihai Jia Wei Zhang | 2015 | Journal of Animal Science and Biotechnology2015，6，4： | 18 |

| 5 | The HuangZaoSi Maize Genome Provides Insights into Genomic Variation and Improvement History of Maize显示文摘Maize is a globally important crop that was a classic model plant for genetic studies. Here, we report a 2.2 Gb draft genome sequence of an elite maize line, HuangZaoSi (HZS). Hybrids bred from HZS-improved lines (HILs) are planted in more than 60% of maize fields in China. Proteome clustering of six completed sequeneed maize genomes show that 638 proteins fall into 264 HZS-specific gene families with the majority of contributions from tandem duplication events. Resequencing and comparative analysis of 40 HZSrelated lines reveals the breeding history of HILs. More than 60% of identified selective sweeps were clustered in identity.by.descent conserved regions, and yield-related genes/QTLs were enriched in HZS characteristic selected regions. Furthermore, we dem on strated that HZS-specific family genes were not uniformly distributed in the genome but enriched in improvement/function.related genomic regions. This study provides an important and novel resource for maize genome research and expands our knowledge on the breadth of genomic variation and improvement history of maize. | Chunhui Li Wei Song Yingfeng Luo Shenghan Gao Ruyang Zhang Zi Shi Xiaqing Wang Ronghuan Wang Fengge Wang Jidong Wang Yanxin Zhao Aiguo Su Shuai Wang Xin Li Meijie Luo Shuaishuai Wang Yunxia Zhang Jianrong Ge Xinyu Tan Ye Yuan Xiaochun Bi Hang He Jianbing Yan Yuandong Wang Songnian Hu Jiuran Zhao | 2019 | Molecular Plant2019，12，3： | 15 |
| 6 | Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development. | Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding | 2020 | Science China Chemistry2020，63，6： | 15 |
| 7 | MCP-1-induced ERK/GSK-3β/Snail signaling facilitates the epithelial-mesenchymal transition and promotes the migration of MCF-7 human breast carcinoma cells显示文摘Monocyte chemoattractant protein-1(MCP-1)is a chemotactic cytokine that can bind to its receptor cysteine-cysteine chemokine receptor 2(CCR2)and plays an important role in breast cancer cell metastasis.However,the molecular mechanisms underlying MCP-1-induced alterations in cellular functions during tumor progression are poorly understood.Here,we showed that MCP-1 stimulated the epithelial-mesenchymal transition(EMT)and induced the tumorigenesis of breast cancer cells by downregulating E-cadherin,upregulating vimentin and fibronectin,activating matrix metallopeptidase-2(MMP-2),and promoting migration and invasion.Moreover,MCP-1 treatment reduced glycogen synthase kinase-3β(GSK-3β)activity via the MEK/ERK-mediated phosphorylation of serine-9 in MCF-7 cells.The inhibition of MEK/ERK by U0126 attenuated the MCP-1-induced phosphorylation of GSK-3βand decreased the expression of Snail,an EMT-related transcription factor,leading to the inhibition of MCF-7 cell migration and invasion.Inactivation of GSK-3βby LiCl(lithium chloride)treatment notably increased MMP-2 activity,vascular endothelial growth factor expression and EMT of MCF-7 cells.These findings revealed that MCP-1-induced EMT and migration are mediated by the ERK/GSK-3β/Snail pathway,and identified a potential novel target for therapeutic intervention in breast cancer. | Shun Li Juan Lu Yu Chen Niya Xiong Li Li Jing Zhang Hong Yang Chunhui Wu Hongjuan Zeng Yiyao Liu | 2017 | Cellular & Molecular Immunology2017，14，7： | 14 |

| 10 | Social Network Information Propagation Model Based on Individual Behavior显示文摘In this paper, we discuss building an information dissemination model based on individual behavior. We analyze the individual behavior related to information dissemination and the factors that affect the sharing behavior of individuals, and we define and quantify these factors. We consider these factors as characteristic attributes and use a Bayesian classifier to classify individuals. Considering the forwarding delay characteristics of information dissemination, we present a random time generation method that simulates the delay of information dissemination. Given time and other constraints, a user might not look at all the information that his/her friends published. Therefore, this paper proposes an algorithm to predict information visibility, i.e., it estimates the probability that an individual will see the information. Based on the classification of individual behavior and combined with our random time generation and information visibility prediction method, we propose an information dissemination model based on individual behavior. The model can be used to predict the scale and speed of information propagation. We use data sets from Sina Weibo to validate and analyze the prediction methods of the individual behavior and information dissemination model based on individual behavior. A previously proposedinformation dissemination model provides the foundation for a subsequent study on the evolution of the network and social network analysis. Predicting the scale and speed of information dissemination can also be used for public opinion monitoring. | Lejun Zhang Hongjie Li Chunhui Zhao Xiaoying Lei | 2017 | China Communications2017，14，7： | 9 |
| 11 | Non-Resonant Structure Design of Catenary Transformer in Ultrasonic Gear Honing显示文摘To solve the design problem of transformer composed of non-resonant structure in ultrasonic gear-honing, force coupling conditions for moderately thick annular plate (MTAP) and catenary horn are proposed, and the frequency equations of the transformer, which consist of an MTAP and a catenary horn, are derived based on Mindlin's theory. The design parameters of the transformer were obtained by solving the frequency equations with the help of MATLAB, and its mode and frequency were deduced by the modal analysis of finite element method (FEM), which are consistent with the theoretical design demands. The transformer design can be extended from system with thin annular plate to that with MTAP as the theoretical method by the simulation analysis of various ratios of the thickness to radius. | LI Xiangpeng ZHANG Chunhui WANG Shiying | 2012 | Wuhan University Journal of Natural Sciences2012，17，1： | 8 |
| 12 | Efficient hepatic delivery and protein expression enabled by optimized mRNA and ionizable lipid nanoparticle显示文摘mRNA is a novel class of therapeutic modality that holds great promise in vaccination,protein replacement therapy,cancer immunotherapy,immune cell engineering etc.However,optimization of mRNA molecules and efficient in vivo delivery are quite important but challenging for its broad application.Here we present an ionizable lipid nanoparticle(iLNP)based on iBL0713 lipid for in vitro and in vivo expression of desired proteins using codon-optimized mRNAs.mRNAs encoding luciferase or erythropoietin(EPO)were prepared by in vitro transcription and formulated with proposed iLNP,to form iLP171/mRNA formulations.It was revealed that both luciferase and EPO proteins were successfully expressed by human hepatocellular carcinoma cells and hepatocytes.The maximum amount of protein expression was found at 6 h post-administration.The expression efficiency of EPO with codon-optimized mRNA was significantly higher than that of unoptimized mRNA.Moreover,no toxicity or immunogenicity was observed for these mRNA formulations.Therefore,our study provides a useful and promising platform for mRNA therapeutic development. | Tongren Yang Chunhui Li Xiaoxia Wang Deyao Zhao Mengjie Zhang Huiqing Cao Zicai Liang Haihua Xiao Xing-Jie Liang Yuhua Weng Yuanyu Huang | 2020 | Bioactive Materials2020，5，4： | 7 |
| 13 | Spatial-temporal Evolution and Determinants of the Belt and Road Initiative: A Maximum Entropy Gravity Model Approach显示文摘The spatial interaction model is an effective way to explore the geographical disparities inherent in the Belt and Road Initiative(BRI) by simulating spatial flows. The traditional gravity model implies the hypothesis of equilibrium points without any reference to when or how to achieve it. In this paper, a dynamic gravity model was established based on the Maximum Entropy(MaxEnt) theory to estimate and monitor the interconnection intensity and dynamic characters of bilateral relations. In order to detect the determinants of interconnection intensity, a Geodetector method was applied to identify and evaluate the determinants of spatial networks in five dimensions. The empirical study clearly demonstrates a heterogeneous and non-circular spatial structure. The main driving forces of spatial-temporal evolution are foreign direct investment, tourism and railway infrastructure construction, while determinants in different sub-regions show obvious spatial differentiation. Southeast Asian countries are typically multi-island area where aviation infrastructure plays a more important role. North and Central Asian countries regard oil as a pillar industry where power and port facilities have a greater impact on the interconnection. While Western Asian countries are mostly influenced by the railway infrastructure, Eastern European countries already have relatively robust infrastructure where tariff policies provide a greater impetus. | HUANG Qinshi ZHU Xigang LIU Chunhui WU Wei LIU Fengbao ZHANG Xinyi | 2020 | Chinese Geographical Science2020，30，5： | 7 |
| 14 | Mesenteric lymph reperfusion may exacerbate brain injury in a rat model of superior mesenteric artery occlusion shock显示文摘BACKGROUND:The intestinal lymphatic pathway and intestinal ischemia/reperfusion are mainly involved in mesenteric lymph duct ligation or drainage;moreover,intervention by reducing the lymph liquid reflux might relieve lung and other organ dysfunction induced by intestinal ischemia/reperfusion;however,research addressing mesenteric lymph reperfusion (MLR) and brain injury has not yet to be reported.OBJECTIVE:To observe the effect of MLR on brain tissue in a rat model of superior mesenteric artery occlusion (SMAO) shock,and to explore the molecular mechanism of MLR.DESIGN,TIME AND SETTING:A randomized,controlled,animal experiment at a neuro-pathophysiology level was performed at the Institute of Microcirculation,Hebei North University;Department of Pathophysiology,Basic Medical College;Department of Pathology,the First Hospital of Hebei North University between December 2007 and March 2009.MATERIALS:Adenosine triphosphate (ATP) standard was provided by the National Institute for the Control of Pharmaceutical and Biological Products;lactic acid (LA),superoxide dismutase (SOD),malonaldehyde (MDA),nitrogen monoxidum (NO),nitric oxide synthase (NOS),myeloperoxidase (MPO) and ATPase assay kits were provided by Nanjing Jiancheng Bioengineering Institute,China.METHODS:A total of 24 male Wistar rats were randomly divided into four groups.In the sham-surgery group (n=6),both the mesenteric lymph duct and the superior mesenteric artery were not blocked;in the MLR group (n=6),the mesenteric lymph duct was occluded for 1 hour followed by 2-hour reperfusion;in the SMAO group (n=6),the superior mesenteric artery was occluded for 1 hour followed by 2-hour reperfusion;in the MLR + SMAO group (n=6),both the mesenteric lymph duct and superior mesenteric artery were occluded for 1 hour followed by 2-hour reperfusion.MAIN OUTCOME MEASURES:Mean arterial blood pressure prior to and following ischemia/reperfusion;brain tissue morphology levels of LA,MDA,SOD,NO,NOS,MPO,ATPase and ATP following reperfusion.RESULTS:MLR did not cause changes in mean arterial blood pressure,brain tissue morphology,LA,MDA,NO,ATP,SOD,NOS,MPO and ATPase.However,SMAO caused a rapid decrease and gradual increase of mean arterial blood pressure.Neuronal necrosis,degeneration and swelling were observed in brain tissue.Contents of MDA,NO,LA and ATP as well as activities of NOS and MPO were significantly increased (P < 0.05),but activities of SOD and Na+-K+-ATPase were significantly decreased (P < 0.05).MLR aggravated neuronal damage in a rat model of SMAO shock.Following MLR,mean arterial blood pressure was significantly decreased (P < 0.05),contents of MDA and NO as well as activities of NOS and MPO were significantly increased (P < 0.05),but activities of Ca2+-ATPase,Mg2+-ATPase and Ca2+-Mg2+-ATPase as well as ATP content were significantly decreased (P < 0.05).CONCLUSION:MLR aggravates brain injury in a rat model of SMAO shock,which correlates with oxygen-derived free radical injury,NO synthesis and release,sequestration of neutrophilic granulocytes,decreasing activity of cell membrane pumps and energy metabolism dysfunction.Pathogenesis of the intestinal lymphatic pathway should be thoroughly investigated to prevent ischemia/reperfusion injury. | Zigang Zhao Chunyu Niu Aimin Shang Jiaming Tian Rui Han Chunhui Zhang Yuping Zhang Jing Zhang | 2010 | Neural Regeneration Research2010，5，9： | 7 |
| 15 | Influence of lactic acid bacteria on physicochemical indexes,sensory and flavor characteristics of fermented sea buckthorn juice显示文摘Sea buckthorn has been proved to be a good substrate for lactic acid bacteria(LAB),but the research on the fermentation of sea buckthorn juice(SBJ)by LAB is still rare.This study was designed to determine the performance of fermented SBJ(FSBJ)in four LAB and investigate the sensory aspects of FSBJ.The results showed that the utilization rates of reducing sugar,titratable acid,and malic acid of SBJ fermented by Lactobacillus casei(SBJLc)were the highest and that lactic acid content was the greatest.The organic acid compositions of the four kinds of FSBJs were also different.The viable counts of all FSBJs was greater than 7 log CFU/mL,and that the viable count of SBJ fermented by SBJLc was the highest.In this study,the Electronic tongue combined with Electronic nose was used for the first time to study SBJ.Results showed that compared with the control,the response value of Sourness was significantly increased,while Bitterness and Astringency were significantly decreased.There was a significant difference in four FSBJs.The results of the electronic nose showed that SBJ fermented by Lactobacillus plantarum LP56(SBJLp)could be well identified by sensors sensitive to aromatic substances.The volatile compound contents before and after fermentation were significantly different,the highest being SBJLp.Finally,the results of sensory evaluation experiments showed that SBJLp was the most acceptable to consumers in terms of sensory evaluation. | Yuanye Liu Jie Sheng Jingjing Li Panling Zhang Fengxian Tang Chunhui Shan | 2022 | Food Bioscience2022，46，2： | 6 |
| 16 | The Research on Social Networks Public Opinion Propagation Influence Models and Its Controllability显示文摘Public opinion propagation control is one of the hot topics in contemporary social network research. With the rapid dissemination of information over the Internet, the traditional isolation and vaccination strategies can no longer achieve satisfactory results. A positive guidance technology for public opinion diffusion is urgently needed. First, based on the analysis of influence network controllability and public opinion diffusion, a positive guidance technology is proposed and a new model that supports external control is established. Second, in combination with the influence network, a public opinion propagation influence network model is designed and a public opinion control point selection algorithm(POCDNSA) is proposed. Finally, An experiment verified that this algorithm can lead to users receiving the correct guidance quickly and accurately, reducing the impact of false public opinion information; the effect of CELF is no better than that of the POCDNSA algorithm. The main reason is that the former is completely based on the diffusion cascade information contained in the training data, but does not consider the specific situation of the network structure and the diffusion of public opinion information in the closed set. thus, the effectiveness and feasibility of the algorithm is proven. The findings of this article therefore provide useful insights for the implementation of public opinion control. | Lejun Zhang Tong Wang Zilong Jin Nan Su Chunhui Zhao Yongjun He | 2018 | China Communications2018，15，7： | 6 |
| 17 | A Covert Communication Method Using Special Bitcoin Addresses Generated by Vanitygen显示文摘As an extension of the traditional encryption technology,information hiding has been increasingly used in the fields of communication and network media,and the covert communication technology has gradually developed.The blockchain technology that has emerged in recent years has the characteristics of decentralization and tamper resistance,which can effectively alleviate the disadvantages and problems of traditional covert communication.However,its combination with covert communication thus far has been mostly at the theoretical level.The BLOCCE method,as an early result of the combination of blockchain and covert communication technology,has the problems of low information embedding efficiency,the use of too many Bitcoin addresses,low communication efficiency,and high costs.The present research improved on this method,designed the V-BLOCCE which uses base58 to encrypt the plaintext and reuses the addresses generated by Vanitygen multiple times to embed information.This greatly improves the efficiency of information embedding and decreases the number of Bitcoin addresses used.Under the premise of ensuring the order,the Bitcoin transaction OP_RETURN field is used to store the information required to restore the plaintext and the transactions are issued at the same time to improve the information transmission efficiency.Thus,a more efficient and feasible method for the application of covert communication on the blockchain is proposed.In addition,this paper also provides a more feasible scheme and theoretical support for covert communication in blockchain. | Lejun Zhang Zhijie Zhang Weizheng Wang Rasheed Waqas Chunhui Zhao Seokhoon Kim Huiling Chen | 2020 | Computers, Materials & Continua2020，，10： | 6 |

| 20 | Alkali metal salts doped pluronic block polymers as electron injection/transport layers for high performance polymer light-emitting diodes显示文摘A series of alkali metal salts doped pluronic block copolymer F127 were used as electron injection/transport layers (ETLs) for polymer light-emitting diodes with poly[2-(4-(3′,7′-dimethyloctyloxy)-phenyl)-p-phenylenevinylene] (P-PPV) as the emission layer. It was found that the electron transport capability of F127 can be effectively enhanced by doping with alkali metal salts. By using Li2CO3 (15%) doped F127 as ETL, the resulting device exhibited improved performance with a maximum luminous efficiency (LE) of 13.59 cd/A and a maximum brightness of 5529 cd/m2, while the device with undoped F127 as ETL only showed a maximum LE of 8.78 cd/A and a maximum brightness of 2952 cd/m2. The effects of the doping concentration, cations and anions of the alkali metal salts on the performance of the resulting devices were investigated. It was found that most of the alkali metal salt dopants can dramatically enhance the electron transport capability of F127 ETL and the performance of the resulting devices was greatly improved. | ZHANG Kai LIU ShengJian GUAN Xing DUAN ChunHui ZHANG Jie ZHONG ChengMei WANG Lei HUANG Fei CAO Yong | 2012 | Science China Chemistry2012，55，5： | 5 |
