| 1 | Mineralogical and geochemical features of sulfide chimneys from the 49°39′E hydrothermal field on the Southwest Indian Ridge and their geological inferences显示文摘During January–May in 2007,the Chinese research cruise DY115-19 discovered an active hydrothermal field at 49°39′E/37°47′S on the ultraslow spreading Southwest Indian Ridge (SWIR).This was also the first active hydrothermal field found along an ultraslow-spreading ridge.We analyzed mineralogical,textural and geochemical compositions of the sulfide chimneys obtained from the 49°39′E field.Chimney samples show a concentric mineral zone around the fluid channel.The mineral assemblages of the interiors consist mainly of chalcopyrite,with pyrite and sphalerite as minor constitunets.In the intermediate portion,pyrite becomes the dominant mineral,with chalcopyrite and sphalerite as minor constitunets.For the outer wall,the majority of minerals are pyrite and sphalerite,with few chalcopyrite.Towards the outer margin of the chimney wall,the mineral grains become small and irregular in shape gradually,while minerals within interstices are abundant.These features are similar to those chimney edifices found on the East Pacific Rise and Mid-Atlantic Ridge.The average contents of Cu,Fe and Zn in our chimney samples were 2.83 wt%,45.6 wt% and 3.28 wt%,respectively.The average Au and Ag contents were up to 2.0 ppm and 70.2 ppm respectively,higher than the massive sulfides from most hydrothermal fields along mid-ocean ridge.The rare earth elements geochemistry of the sulfide chimneys show a pattern distinctive from the sulfides recovered from typical hydrothermal fields along sedimentstarved mid-ocean ridge,with the enrichment of light rare earth elements but the weak,mostly negative,Eu anomaly.This is attributed to the distinct mineralization environment or fluid compositions in this area. | TAO ChunHui LI HuaiMing HUANG Wei HAN XiQiu WU GuangHai SU Xin ZHOU Ning LIN Jian HE YongHua ZHOU JianPing | 2011 | Chinese Science Bulletin2011，56，26： | 34 |
| 2 | Early tectonic uplift of the northern Tibetan Plateau显示文摘The Hexi Corridor is the northmost foreland basin of the Tibetan Plateau and its formation is controlled by the northern marginal fault of Tibet, Altyn Tagh Fault (ATF)-North Qilian Shan marginal Fault (NQF), and the southern Kuantan Shan-Longshou Shan Fault (KLF). So its study is important to understanding the mechanism of Tibet formation and its influence on global climate change. The oldest Cenozoic sediments in the Corridor is the Huoshaogou Formation which consists of terrigenous fine conglomerate, sandstone, sandy mudstone and mudstone, depositing in alluvial to lacustrine and fan delta sedimentary environments. Detailed paleomagnetic measurements of this sequence at Yumen clearly reveal eleven pairs of normal and reversed polarities. Fossil mammals found around the section support that most of the observed polarities can be well correlated with chrons between 13n and 18r of the standard geomagnetic polarity time scale, yielding ages of 40.2-33.35 Ma. The mean declinations of this sequence and its immediately above stratigraphy indicate an 18.3° rapid clockwise rotation of the Hexi Corridor. Since this sequence has been strongly folded and is capped by an angular unconformity, we think that the presence of the thick alluvial fan conglomeration at the bottom of the foreland basin may indicate the initial deformation and uplift of the northern Qilian Shan. This process could occur at latest at 40.2 Ma, driven by the faults NQF and KLF that thrust onto the Hexi corridor respectively from its southern and northern margins. These faults are in an early response to the collision of India with Asia, while the unconformable termination and rotation of the Huoshaogou Formation at ~33.35 Ma indicate other early episode of rapid tectonic deformation and uplift of the northern Tibet. | DAI Shuang FANG Xiaomin SONG Chunhui GAO Junping GAO Donglin LI Jijun | 2005 | Chinese Science Bulletin2005，50，15： | 30 |
| 3 | 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 |
| 4 | Comparative effect of electroacupuncture and moxibustion on the expression of substance P and vasoactive intestinal peptide in patients with irritable bowel syndrome显示文摘OBJECTIVE: To compare the impacts of electroacupuncture(EA) and moxibustion(Mox) on the primary gastrointestinal symptoms and the expressions of colonic mucosa-associated neuropeptide substance P(SP) and vasoactive intestinal peptide(VIP)in patients with either diarrhea-predominant or constipation-predominant irritable bowel syndrome(IBS-D and IBS-C,respectively).METHODS: Eighty-five IBS patients were randomly allocated to the EA and Mox groups. Zusanli(ST 36)and Shangjuxu(ST 37) were selected as acupoints for electroacupuncture or warm moxibustion treatment once a day for 14 consecutive days. Before and after the treatment sessions,a Visual Analog Pain Scale and the Bristol Stool Form Scale were used to evaluate gastrointestinal symptoms. There were four dropout cases,leaving 81 participants(41 with IBS-D and 40 with IBS-C) who volunteered to undergo colonoscopy before and after the treatment sessions. During colonoscopy,sigmoid mucosa were collected to detect SP and VIP expression using immunohistochemistry assay.RESULTS: Both EA and Mox treatments were effective at relieving abdominal pain in IBS-D and IBS-C patients. However,Mox was more effective at reducing diarrhea in IBS-D patients,whereas EA was more effective at improving constipation in IBS-C patients. EA and Mox treatments both down-regulated the abnormally increased SP and VIP expression in the colonic mucosa,with no significant difference shown between the two treatments.CONCLUSION: Both EA and Mox treatments are effective at ameliorating gastrointestinal symptoms by reducing SP and VIP expression in the colonic mucosa of IBS patients. | Lu Zhenzhong Yin Xiaojun Teng Weijun Chen Yuehua Sun Jie Zhao Jimeng Wang Anqi Bao Chunhui Shi Yin | 2015 | Journal of Traditional Chinese Medicine2015，35，4： | 24 |

| 6 | 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 |
| 7 | 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 |
| 8 | Characteristics and Source Identification of Polycyclic Aromatic Hydrocarbons (PAHs) in Urban Soils: A Review显示文摘Polycyclic aromatic hydrocarbons(PAHs) are mainly produced by combustion processes and consist of a number of toxic compounds.They are always emitted as a mixture and have become a major type of pollutants in urban areas.The degree of soil contamination by PAHs is of special concern in areas immediately in proximity to cities with heavy traffic,factories,older buildings,and infrastructure.The accumulation of soil PAHs is also affected by non-anthropogenic factors,such as climate,vegetation,and soil property.This paper reviews three typical source identification techniques,including diagnostic ratios,positive matrix factorization,and principle components analysis.The advantages or disadvantages of these techniques are analyzed.It is recommended that multiple identification techniques be used to determine the sources in order to minimize the weaknesses inherent in each method and thereby to strengthen the conclusions for PAH source identification. | WANG Chunhui WU Shaohua ZHOU Shenglu SHI Yaxing SONG Jing | 2017 | Pedosphere2017，27，1： | 18 |

| 10 | 2D DEM simulation of particle mixing in rotating drum: A parametric study显示文摘Mixing behaviors of equal-sized glass beads in a rotating drum were investigated by both DEM simulations and experiments. The experiments indicated that higher rotation speed can significantly enhance mixing. The particle profiles predicted by 2D DEM simulation were compared with the experimental results from a quasi-2D drum, showing inconsistency due to reduction of contacts in the single-layer 2D simulation which makes the driving friction weaker than that in the quasi-2D test, better results could be reached by specifying a higher frictional coefficient between the particles and the cylinder wall. In order to explore the influences of physical properties (density, size or friction) on mixing behavior, numerical 2D simulations were carried out systematically, in which one examined specific property being examined was exaggerated while the others were kept the same as that in the control group. The DEM simulations reveal that particle density and size are the dominating factors affecting mixing behaviors, while the effect of frictional coefficient is less significant. However, segregation due to any of the factors can be diminished by specifying a proper particle size distribution (multi-size with lower size ratio). | Yong Xu Chunhui Xu Zhe Zhou Jing Du Daping Hu | 2010 | Particuology2010，8，2： | 16 |
| 11 | 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 |
| 12 | 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 |
| 13 | 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 |

| 15 | The Genesis Mechanism of the Mantle Fluid Action and Evolution in the Ore-Forming Process: A Case Study of the Laowangzhai Gold Deposit in Yunnan, China显示文摘Based on petrological studies of the wall rocks, mineralizing rocks, ores and veins from the Laowangzhai gold deposit, it is discovered that along with the development of silication, carbonation and sulfidation, a kind of black opaque ultra-microlite material runs through the spaces between grains, fissures and cleavages. Under observations of the electron microprobe, scanning electronic microscopy and energy spectrum, this kind of ultra-microlite material is confirmed to consist of ultra microcrystalline quartz, silicate, sulfides and carbonates, as well as rutile, scheelite and specularite (magnetite), showing characters of liquation by the analyses of SEM and energy spectrum. The coexistence of immiscibility and precipitating co-crystallization strongly suggests that the mineralizing fluid changed from the melt to the hydrothermal fluid. Combined with the element geochemical researches, it is realized that the ultra-microlite aggregate is the direct relics of the mantle fluid behaving like a melt and supercritical fluid, which goes along with the mantle-derived magma and will escape from the magma body at a proper time. During the alteration process, the nature of the mantle fluid changed and it is mixed with the crustal fluid, which are favorable for mineralization in the Loawangzhai gold deposit. | LIU Xianfan LI Chunhui LU Qiuxia DENG Biping SONG Xiangfeng ZHAO Fufeng CHU Yating XIAO Jixiong YI Liwen HUANG Yupeng | 2012 | Acta Geologica Sinica(English Edition)2012，86，3： | 13 |

| 19 | Formation control and collision avoidance for multi-UAV systems based on Voronoi partition显示文摘This paper deals with the formation control problem of multiple unmanned aerial vehicles(UAVs) with collision avoidance. A distributed formation control and collision avoidance method is proposed based on Voronoi partition and conventional artificial potential field. The collision avoidance is achieved by partitioning the whole space into non-overlapping regions based on Voronoi partition theory, which is taken as the task region to confine the movement of each UAV. The general motion control law is designed based on the conventional artificial potential field. As this often leads to local optimum when two UAVs are going to collide with each other and they may stay still where the repulsive force is adversely equivalent to the attractive force. To address this problem,the destination switch scheme is further proposed to let UAVs switch destinations when they reach the local equilibrium. Finally,the effectiveness of proposed formation control algorithm is validated by simulations and experiments. | HU JinWen WANG Man ZHAO ChunHui PAN Quan DU Chang | 2020 | Science China(Technological Sciences)2020，63，1： | 12 |
| 20 | Late Cenozoic high-resolution magnetostratigraphy in the Kunlun Pass Basin and its implications for the uplift of the northern Tibetan Plateau显示文摘The Kunlun Pass Basin, located in the middle of the eastern Kunlun Mountains, received relatively continuous late Cenozoic sediments from the surrounding mountains, archiving great information to understand the deformation and uplift histories of the northern Tibetan Plateau. The Kunlun-Yellow River Movement, identified from the tectonomorphologic and sedimentary evolution of the Kunlun Pass Basin by Cui Zhijiu et al. (1997, 1998), is roughly coincident with many important global and Plateau climatic and environmental events, becoming a crucial time interval to understand tectonic-climatic interactions. However, the ages used to constrict the events remain great uncertainty. Here, we present the results of detailed magnetostratigraphy of the late Cenozoic sediments in the Kunlun Pass Basin, which show the basin sediments were formed between about 3.6 Ma and 0.5 Ma and the Kunlun-Yellow River Movement occurred at 1.2 to ~0.78 Ma. The lithology, sedimentary facies and lithofacies associations divide the basin into five stages of tectonosedimentary evolution, indicating the northern Tibetan Plateau having experienced five episodes of tectonic uplifts at ~3.6, 2.69-2.58, 1.77, 1.2, 0.87 and ~0.78 Ma since the Pliocene. | SONG Chunhui GAO Dongling FANG Xiaomin CUI Zhijiu LI Jijun YANG Shengi JIN Hongbo Douglas Burbank Joseph L.
