| 1 | Ridge subduction and porphyry copper-gold mineralization:An overview显示文摘Many large porphyry Cu-Au deposits are connected to adakitic rocks known to be closely associated with ridge subduction. For example, there are several subducting ridges along the east Pacific margin, e.g., in Chile, Peru, and South America, most of which are associated with large porphyry Cu-Au deposits. In contrast, there are much fewer ridge subductions on the west Pacific margin and porphyry Cu-Au deposits are much less there, both in terms of tonnage and the number of deposits. Given that Cu and Au are moderately incompatible elements, oceanic crust has much higher Cu-Au concentrations than the mantle and the continental crust, and thus slab melts with their diagnostic adakitic chemistry have systematically higher Cu and Au, which is favorable for mineralization. Considering the geotherm of subducting slabs in the Phanerozoic, ridge subduction is the most favorable tectonic setting for this. Therefore, slab melting is the likely link in the spatial association between ridge subduction and Cu-Au deposits. Geochemical signatures of slab melting and hence maybe ridge subduction in less eroded regions in eastern China, the central Asian orogenic belt etc. may indicate important exploration targets for large porphyry Cu-Au deposits. | SUN WeiDong LING MingXing YANG XiaoYong FAN WeiMing DING Xing LIANG HuaYing | 2010 | Science China Earth Sciences2010,53,4: | 97 |
| 2 | Optimization design and test of rice plug seedling transplanting mechanism of planetary gear train with incomplete eccentric circular gear and non-circular gears显示文摘In order to solve the problem of the high-speed mechanized transplanting of rice plug seedlings,the design requirements of transplanting mechanism for rice plug seedlings were analyzed and a kind of rice plug seedling transplanting mechanism of planetary gear train based on the drive with incomplete eccentric circular gear and non-circular gears was designed innovatively.The laboratory kinematics was examined.The working principle of the transplanting mechanism for rice plug seedlings was studied,kinematics analysis of the transplanting mechanism was carried out and its kinematic model was set up.A human-computer interaction optimization method was used to optimize the parameters of the transplanting mechanism.The computer aided analysis and optimization software of the transplanting mechanism based on Visual Basic 6.0 was developed.Through analyzing the influence of design variables on the optimization objectives of the transplanting mechanism,a set of parameters of the transplanting mechanism which meet the requirements of transplanting trajectory and posture for transplanting rice seedlings were obtained by means of human-computer interaction.The structure of the transplanting mechanism was designed according to this set of parameters,and its virtual prototype and physical prototype were set up and manufactured,respectively.The kinematic simulation test and high-speed photography kinematic test of the transplanting mechanism were conducted to obtain its kinematic performances,such as transplanting trajectory and posture.The results of bench test,simulation analysis and theoretical analysis were almost in agreement,which verified the correctness of the theoretical model and design results of the transplanting mechanism,indicating that the optimized transplanting mechanism can satisfy the requirements of transplanting rice seedlings and be applied in the rice plug seedling transplanter. | Ye Bingliang Yi Weiming Yu Gaohong Gao Yang Zhao Xiong | 2017 | International Journal of Agricultural and Biological Engineering2017,10,6: | 31 |
| 3 | The oasis expansion and eco-environment change over the last 50 years in Manas River Valley, Xinjiang显示文摘The oasis expansion and economic development of the Manas River Valley is one of the most successful examples in Xinjiang. In this paper, the oasis spatial distribution pattern and dynamic change were examined using imageries of Landsat MSS, TM and ETM, land use and topographic maps in six different periods (such as 1949, 1962, 1976, 1989, 1999 and 2001) over the last 50 years in the valley. The oasis expansion process could be divided into two stages according to the annual rate of oasis area increase, the fast oasization stage (from 1949 to 1976) when the oasis area ex-panded from 156.385 km2 in 1949 to 3,639.491 km2 in 1976 because of rapidly increased population and quickly enlarged farmland area; and the urbanization stage (from 1976 to 2001) when the ex-pansion ratio of farmland slowed down, and the urbanization process quickened, the total oasis area reached 5042.440 km2 in 2001. With the continuous expansion of oasis and farmland, a large quantity of river water was drawn into irrigation ditch and plain lakes, so only a small quantity of river water could flow into lakes, as a result, the Manas Lake dried up, salization and basification problems happened in the low-lying oasis region. The natural swamp around the lake was shrunk greatly and biodiversity decreased significantly. The driving force analysis reveals that human activities, such as reclamation and population growth, played a major role in the oasis expansion and ecological dete-rioration in the Manas River Valley. So further efforts should be made to improve the efficiency of water resource utility and adjust layout of the regional agricultural and animal husbandry to keep the sustainable development of oasis economic belt of the northern slope of Tianshan Mts. | CHENG Weiming ZHOU Chenghu LIU Haijiang ZHANG Yang JIANG Yan ZHANG Yichi YAO Yonghui | 2006 | Science China Earth Sciences2006,49,2: | 24 |
| 4 | Petrogenesis and tectonic implications of Late-Triassic high εNd(t)-εHf(t) granites in the Ailaoshan tectonic zone(SW China)显示文摘High εNd(t)-εHf(t) granites are robust evidence for crustal growth. In this paper we report results of petrologic, geochronological and geochemical investigations on the Huashiban granites from the Ailaoshan tectonic zone in western Yunnan(SW China). Zircon grains separated from the two samples(10HH-119 A and 10HH-120A) yield the weighted mean 206Pb/238 U ages of 229.9 ± 2.0 Ma and 229.3 ± 2.3 Ma, respectively, interpreted as the crystallization ages of the granites. Based on our results, in combination with the existing U-Pb geochronological data for the Ailaoshan metamorphic rocks, we propose that the Ailaoshan Group might be a rock complex composed of the Mesoproterozoic, Neoproterozoic, Hercynian, Indosinian and Himalayan components, rather than a part of the crystalline basement of the Yangtze block. The zircon grains show highly depleted Lu-Hf isotope compositions, with positive εHf(t) values ranging from 8.4 to 13.1. The Huashiban granites have high SiO2(72.66 wt%–73.70 wt%), low Mg#(0.28–0.34) with A/CNK=1.01–1.05, and can be classified as peralumious high-K calc-alkaline I-type granites. A synthesis of these data indicates that the Ailaoshan tectonic zone had evolved into a post-collisional setting by the Late-Triassic(229 Ma). Genesis of the Huashiban high εNd(t)-εHf(t) granites involved into two processes:(1) underplating of the sub-arc mantle into the lower crust, and(2) remelting of the juvenile crustal materials in response to the upwelling of the asthenospheric mantle in the post-collisional setting. | LIU HuiChuan WANG YueJun FAN WeiMing ZI JianWei CAI YongFeng YANG GuangLin | 2014 | Science China Earth Sciences2014,57,9: | 12 |

| 6 | Application of Two-Dimensional Electrophoresis in the Research of Retinal Proteins of Diabetic Rat显示文摘Diabetes mellitus (DM) is a chronic disease which is associated with numerous serious health complications such as diabetic retinopathy, and is the leading cause of new cases of blindness in adults at the age of 20-74 years old. The aim of the study was to establish and optimize a two-dimensional polyacrylamide gel electrophoresis (2-DE) technique for retina proteomics to improve the resolution and reproducibility, and to observe the proteomic changes of retinal tissues in diabetic and normal rats. Proteins were extracted from retinal tissues of normal and 8 weeks diabetic SD rats and used in two-dimensional electrophoresis. Various conditions of retina proteomic 2-DE were adjusted, optimized and protein spots of differential expression were obtained through analysis of 2-DE images with PDQuest software. By choosing appropriate sample amount, using pre-cast IPG dry strips (pH 5-8) and casting 12% equal gel, satisfactory 2-DE images of retina were obtained and a steady 2-DE technique was established. In this way, we found 36 spots in 2-DE gel of diabetic retinas that exhibited statistically significant variations, including up-regulation of 5 proteins in diabetic rat retinas, down-regulation of 23, and disappearance of 8, in comparison with normal tissues. The differences of protein expression were observed in retinas between diabetic and normal rats. Our established 2-DE technique of retina proteins could be effectively applied in proteomics of retina diseases. | Shangqing Liu Yanyan Zhang Xianyong Xie Weiming Hu Rong Cai Jian Kang Huijun Yang | 2007 | Cellular & Molecular Immunology2007,4,1: | 9 |
| 7 | BLT1 in dendritic cells promotes Th1/Th17 differentiation and its deficiency ameliorates TNBS-induced colitis显示文摘Leukotriene B4(LTB4)synthesis is enhanced in the colonic mucosa in patients with inflammatory bowel disease(IBD).BLT1,a highaffinity receptor for LTB4,exhibits no effect on the progression of dextran sodium sulfate(DSS)-induced colitis,which mostly relies on innate immunity.Here,we reported that BLT1 regulates trinitrobenzene sulfonic acid(TNBS)-induced colitis,which reflects CD4+T-cell-dependent adaptive immune mechanisms of IBD.We found that BLT1 signaling enhanced the progression of colitis through controlling the production of proinflammatory cytokines by dendritic cells(DCs)and modulating the differentiation of Th1 and Th17.BLT1−/−mice displayed an alleviated severity of TNBS-induced colitis with reduced body weight loss and infiltrating cells in the lamina propria.BLT1 deficiency in DCs led to reduced production of proinflammatory cytokines,including IL-6,TNF-α,and IL-12,and these results were further confirmed via treatment with a BLT1 antagonist.The impaired cytokine production by BLT1−/−DCs subsequently led to reduced Th1 and Th17 differentiation both in vitro and in vivo.We further performed a conditional DC reconstitution experiment to assess whether BLT1 in DCs plays a major role in regulating the pathogenesis of TNBS-induced colitis,and the results indicate that BLT1 deficiency in DCs also significantly reduces disease severity.The mechanistic study demonstrated that BLT1-regulated proinflammatory cytokine production through the Gαiβγsubunit-phospholipase Cβ(PLCβ)-PKC pathway.Notably,we found that treatment with the BLT1 antagonist also reduced the production of proinflammatory cytokines by human peripheral blood DCs.Our findings reveal the critical role of BLT1 in regulating adaptive immunity and TNBS-induced colitis,which further supports BLT1 as a potential drug target for adaptive immunity-mediated IBD. | Jinfeng Zhou Weiming Lai Wanjie Yang Juping Pan Hu Shen Yingying Cai Cuixia Yang Ningjia Ma Yue Zhang Ru Zhang Xin Xie Zhongjun Dong Yuan Gao Changsheng Du | 2018 | Cellular & Molecular Immunology2018,15,12: | 9 |

| 9 | Comparative Analysis of Leaf Trichomes, Epidermal Wax And Defense Enzymes Activities in Response to Puccinia horiana in Chrysanthemum and Ajania Species显示文摘White rust caused by Puccinia horiana is a destructive disease of chrysanthemum plants.To better understand the resistance mechanisms of composite species to this disease,the leaf cuticular traits,antioxidant and defensive enzymes activities of immune(Chrysanthemum makinoi var.wakasaense)and highly susceptible(Ajania shiwogiku var.kinokuniense)species were compared.Trichome density of two species was markedly different,negatively associated with plant resistance to P.horiana.Total wax load in C.makinoi var.wakasaense was two times more than that in A.shiwogiku var.kinokuniense.The wax composition in immune one was abundant in esters and primary alcohols.Superoxide dismutase(SOD,EC 1.15.1.1),peroxidase(POD,EC 1.11.1.7),polyphenoloxidase(PPO,EC 1.14.18.1 or EC 1.10.3.2)and phenylalanine ammonia lyase(PAL,EC 4.3.1.5)activitieswere investigated.In C.makinoi var.wakasaense,the activity of SOD and POD increased rapidly after inoculation,whichmight be non-host induced reactive oxygen species(ROS)activated antioxidant enzymes,however SOD and POD remained a low and steady level in the highly susceptible one after inoculation.Quick increase in PPO activities after inoculation was observed in both species,however it remained higher in C.makinoi var.wakasaense at the late period of inoculation.PAL in C.makinoi var.wakasaense was induced after pathogen inoculation,but not in A.shiwogiku var.kinokuniense,suggesting that these two enzymes might contribute to the resistance to P.horiana. | Yinjie Wang Jun Zeng Xiaolong Xia Yang Xu Jing Sun Jing Gu Hainan Sun Haini Lei Fadi Chen Jiafu Jiang Weiming Fang Sumei Chen | 2020 | Horticultural Plant Journal2020,6,3: | 8 |
| 10 | Whole-genome sequencing provides insights into the genetic diversity and domestication of bitter gourd(Momordica spp.)显示文摘Bitter gourd(Momordica charantia)is a popular cultivated vegetable in Asian and African countries.To reveal the characteristics of the genomic structure,evolutionary trajectory,and genetic basis underlying the domestication of bitter gourd,we performed whole-genome sequencing of the cultivar Dali-11 and the wild small-fruited line TR and resequencing of 187 bitter gourd germplasms from 16 countries.The major gene clusters(Bi clusters)for the biosynthesis of cucurbitane triterpenoids,which confer a bitter taste,are highly conserved in cucumber,melon,and watermelon.Comparative analysis among cucurbit genomes revealed that the Bi cluster involved in cucurbitane triterpenoid biosynthesis is absent in bitter gourd.Phylogenetic analysis revealed that the TR group,including 21 bitter gourd germplasms,may belong to a new species or subspecies independent from M.charantia.Furthermore,we found that the remaining 166 M.charantia germplasms are geographically differentiated,and we identified 710,412,and 290 candidate domestication genes in the South Asia,Southeast Asia,and China populations,respectively.This study provides new insights into bitter gourd genetic diversity and domestication and will facilitate the future genomics-enabled improvement of bitter gourd. | Junjie Cui Yan Yang Shaobo Luo Le Wang Rukui Huang Qingfang Wen Xiaoxia Han Nansheng Miao Jiaowen Cheng Ziji Liu Changyuan Zhang Chengcheng Feng Haisheng Zhu Jianwen Su Xinjian Wan Fang Hu Yu Niu Xiaoming Zheng Yulan Yang Dai Shan Zhensheng Dong Weiming He Narinder P.S.Dhillon Kailin Hu | 2020 | Horticulture Research2020,7,1: | 7 |
| 11 | Resveratrol induces AMPK and mTOR signaling inhibition-mediated autophagy and apoptosis in multiple myeloma cells显示文摘Resveratrol,a natural compound extracted from the skins of grapes,berries,or other fruits,has been shown to have anti-tumor effects against multiple myeloma(MM)via promoting apoptosis and inhibiting cell viability.In addition to apoptosis,autophagy also plays a significant role in anti-tumor effects.However,whether autophagy is involved in anti-MM activity of resveratrol remains unclear.In this study,human MM cell lines U266,RPMI-8226,and NCI-H929 were treated with resveratrol.Cell Counting Kit-8 assay and colony formation assay were used to measure cell viability.Western blot analysis was used to detect apoptosis-and autophagy-associated proteins.3-Methyladenine(3-MA)was applied to inhibit autophagy.Results showed that resveratrol inhibited cell viability and colony formation via promoting apoptosis and autophagy in MM cell lines U266,RPMI-8226,and NCI-H929.Resveratrol promoted apoptosis-related proteins,Caspase-3 activating poly-ADP-ribose polymerase and Caspase-3 cleavage,and decreased the protein level of Survivin in a dose-dependent manner.Additionally,resveratrol upregulated the levels of LC3 and Beclin1 in a dose-dependent way,indicating that autophagy might be implicated in anti-MM effect of resveratrol.Furthermore,3-MA relieved the cytotoxicity of resveratrol by blocking the autophagic flux.Resveratrol increased the phosphorylation of adenosine monophosphate(AMP)-activated protein kinase and decreased the phosphorylation of mammalian target of rapamycin(mTOR)and its downstream substrates p70S6K and 4EBP1 in a dose-dependent manner,leading to autophagy.Therefore,our results suggest that resveratrol exerts anti-MM effects through apoptosis and autophagy,which can be used as a new therapeutic strategy for MM in clinic. | Ruye Ma Dandan Yu Yu Peng Hongfei Yi Yingcong Wang Taofang Cheng Bingqing Shi Guang Yang Weiming Lai Xiaosong Wu Ye Lu Jumei Shi | 2021 | Acta Biochimica et Biophysica Sinica2021,53,6: | 7 |

| 13 | Evaluating Soil Dissolved Organic Matter Extraction Using Three-Dimensional Excitation-Emission Matrix Fluorescence Spectroscopy显示文摘Soil dissolved organic matter(DOM) consists of many organic compounds and plays an important role in contaminant transport in the ecosystem. However, the effects of different extraction conditions on contents of different DOM components are poorly understood.We extracted DOM from three soils using different extraction times, solid to liquid ratios(SLR), and extraction solution(KCl)concentrations, and evaluated the extractions using three-dimensional excitation-emission matrix(EEM) fluorescence spectroscopy.The sum of the contents of the main DOM components(protein-, fulvic-, and humic-like compounds) increased by 0.6–3.5, 2.5–3.9,and 0.11–0.37 times(P < 0.05) when SLR decreased from 1:2 to 1:10, the extraction solution concentration increased from 0.01 to 1.5 mol L^(-1), and extraction time increased from 10 to 300 min, respectively. The three-dimensional EEM fluorescence spectroscopy is a useful tool to characterize the components of DOM and evaluate DOM extraction in soils. | XIE Wenming ZHANG Shanshan RUAN Lin YANG Mingyue SHI Weiming ZHANG Hailin LI Weihua | 2017 | Pedosphere2017,27,5: | 6 |

| 15 | An Intra-Oceanic Subduction System Influenced by Ridge Subduction in the Diyanmiao Subduction Accretionary Complex of the Xar Moron Area,Eastern Margin of the Central Asian Orogenic Belt显示文摘This study focuses on the geology,geochemistry,Sr-Nd isotopes and their tectonic settings of three types of basalts in Diyanmiao ophiolite in the Xar Moron area located on the eastern margin of the Central Asian Orogenic Belt.Type I basalts are oceanic tholeiites with a depleted light rare earth element(LREE)pattern,which are similar to the typical N-mid-oceanic ridge basalt(MORB)and suggests that they were formed at a mid-oceanic ridge.The initial 87Sr/86Sr ratios of Type I basalts range from 0.703966 to 0.705276 and theεNd(t)values are from 16.49 to 17.15,indicating that they were derived from a depleted mantle source.Type II basalts belong to the medium-potassium calc-akaline series and have the geochem-ical characteristics of Nb-enriched basalt(NEB)with high Nb content(14.5 ppm)and strong enrichment in LREEs,implying that they were created by the partial melting of mantle wedge peridotite that previously metasomatized by slab melts.Type III basalts are high-Al basalt(HAB)with high-Al contents(Al_(2)0_(3)=16.75 wt.%-18.00 wt.%),distinct Nb depletion and high Th/Yb ratios.Thus they were likely gen-erated in a normal island-arc setting.Therefore,the association of MORB,NEB,and HAB in the study area may be due to the subduction of a mid-oceanic ridge,and the Diyanmiao ophiolite is proposed to be formed in the forearc setting of a mid-oceanic ridge subduction system. | Yang Cheng Qinghui Xiao Tingdong Li Liquan Xu Yuxu Fan Yan Li Lingjun Guo Jinli Pang Weiming Yuan | 2021 | Journal of Earth Science2021,32,1: | 6 |

| 18 | Introducing tree neighbouring relationship factors in forest pattern spatial analysis:weighted Delaunay triangulation method显示文摘It is important to quantify and analyze forest spatial patterns for studying biological characteristics,population interaction and the relationship between the population and environment.In this study,the forest spatial structure unit was generated based on the Delaunay triangulation model(DTM),and the weights were generated using the comprehensive values of the tree diameter at breast height,total height and crown width.The distance between neighbors determined by the DTM was weighted to transform the original coordinates of trees into logical coordinates.Then,a weighted spatial pattern(WSP)was developed.After weighting,the neighboring trees were replaced,the replacement ratio was 38.3%,and there was 57.4%of the central tree.Correlation analysis showed that the uniform angle index of the WSP was significantly correlated with the tree size standard deviation under uniformity(r=0.932)and randomness(r=0.711).The DTM method not only considers the spatial distance between trees,but also considers the non-spatial attributes of trees.By changing the spatial topological relation between trees,this method further improves the spatial structure measurement of forest. | Jianjun Li Kaiwen Zhu Shuai Liu Dan Li Gui Zhang Xing Liu Weiming Yang | 2021 | Journal of Forestry Research2021,32,5: | 4 |
| 19 | Microstructure and soft-magnetic properties of FeCoPCCu nanocrystalline alloys显示文摘Fe(83.2-x)CoxP(10)C6Cu(0.8)(x=0,4,6,8 and 10)alloys with a high amorphous-forming ability and good softmagnetic properties were successfully synthesized.Saturation magnetic flux density(Bs)is effectively enhanced from 1.53 T to 1.61 T for as-quenched alloy by minor Co addition,which is consistent well with the result of the linear relationship between average magnetic moment and magnetic valence.For Cocontained alloys,the value of corecivity(Hc)is mainly determined by magneto-crystalline anisotropy,while effective permeability(μe)is dominated by grain size and average saturation polarization.After proper heat treatment,the Fe(79.2)Co4P(10)C6Cu(0.8)nanocrystalline alloy exhibited excellent soft-magnetic properties including a high Bsof 1.8 T,a low Hcof 6.6 A/m and a highμeof 15,510,which is closely related to the high volume fraction of α-(Fe,Co)grains and refined uniform nanocrystalline microstructure. | Long Hou Xingdu Fan Qianqian Wang Weiming Yang Baolong Shen | 2019 | Journal of Materials Science & Technology2019,35,8: | 3 |
