| 1 | Laparoscopic Partial Nephrectomy With Segmental Renal Artery Clamping:Technique and Clinical Outcomes显示文摘Background:Warm ischemic injury is one of the most important factors affecting renal function in partial nephrectomy(PN).The technique of segmental renal artery clamping emerges as an alternative to conventional renal artery clamping for renal hilar control.Objective:To evaluate the feasibility and efficiency of laparoscopic PN(LPN) with segmental renal artery clamping in comparison with the conventional technique.Design,setting,and participants:A total of 75 patients underwent LPN from June 2007 to November 2009.All patients had T1a or T1b tumor in one kidney and a normal contralateral kidney.Thirty-seven patients underwent surgeries with main renal artery clamping,and 38 underwent surgeries with segmental artery clamping.Intervention:All procedures were performed by the same laparoscopic surgeon.Measurements:Blood loss,operation time,warm ischemia(WI) time,and complications affected renal function before and after operation were recorded.Results and limitations:All LPNs were completed without conversion to open surgery or nephrectomy.The novel technique slightly increased WI time(p < 0.001) and intraoperative blood loss(p = 0.006),while it provided better postoperative affected renal function(p < 0.001) compared with the conventional technique.The total complication rate was 12%.Among the 38 cases where segmental renal artery clamping was performed,7 had to convert to the conventional method.Tumor size and location influenced the number of clamped segmental arteries.Long-term postoperative renal function is still awaited.Conclusions:LPN with segmental artery clamping is safe and feasible in clinical practice.It minimizes the intraoperative WI injury and improves early postoperative affected renal function compared with main renal artery clamping.(C) 2010 European Association of Urology.Published by Elsevier B.V.All rights reserved. | Shao,P.F.

| 2 | Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children. | Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team | 2020 | Neuroscience Bulletin2020，36，9： | 158 |
| 3 | pORF5 plasmid protein of Chlamydia trachomatis induces MAPK-mediated pro-inflammatory cytokines via TLR2 activation in THP-1 cells显示文摘Infection with Chlamydia trachomatis induces inflammatory pathologies in the urogenital tract that can lead to infertility and ectopic pregnancy.Pathogenesis of infection has been mostly attributed to excessive cytokine production.However,precise mechanisms on how C.trachomatis triggers this production,and which protein(s) stimulate inflammatory cytokines remains unknown.In the present study,the C.trachomatis pORF5 protein induced tumor necrosis factor alpha(TNF-α),interleukin-1 beta(IL-1β) and interleukin-8(IL-8) in dose-and time-dependent manners in the THP-1 human monocyte cell line.We found that intracellular p38/mitogen-activated protein kinase(MAPK) and extracellular signal-regulated kinase(ERK)/MAPK signaling pathways were required for the induction of TNF-α,IL-1β and IL-8.Blockade of toll-like receptor 2(TLR2) signaling reduced induction levels of TNF-α,IL-8 and IL-1β.We concluded that the C.trachomatis pORF5 protein might contribute to the inflammatory processes associated with chlamydial infections. | ZHOU Hui HUANG QiuLin LI ZhongYu WU YiMou XIE XiaoBing MA KangKang CAO WenJuan ZHOU Zhou LU ChunXue ZHONG GuangMing | 2013 | Science China(Life Sciences)2013，56，5： | 26 |
| 4 | 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 |
| 5 | Mesenchymal stem cells-derived exosomal microRNAs contribute to wound inflammation显示文摘Clinical and experimental studies have highlighted the significance of inflammation in coordinating wound repair and regeneration.However,it remains challenging to control the inflammatory response and tolerance at systemic levels without causing toxicity to injured tissues.Mesenchymal stem cells(MSCs) possess potent immunomodulatory properties and facilitate tissue repair by releasing exosomes,which generate a suitable microenvironment for inflammatory resolution.Exosomes contain several effective bioactive molecules and act as a cell-cell communication vehicle to influence cellular activities in recipient cells.During this process,the horizontal transfer of exosomal microRNAs(miRNAs) to acceptor cells,where they regulate target gene expression,is of particular interest for understanding the basic biology of inflammation ablation,tissue homeostasis,and development of therapeutic approaches.In this review,we describe a signature of three specific miRNAs(miR-21,miR-146 a,and miR-181) present in human umbilical cord MSC-derived exosomes(MSC-EXO) identified microarray chip analysis and focus on the inflammatory regulatory functions of these immune-related miRNAs.We also discuss the potential mechanisms contributing to the resolution of wound inflammation and tissue healing. | Dongdong Ti Haojie Hao Xiaobing Fu Weidong Han | 2016 | Science China(Life Sciences)2016，59，12： | 24 |

| 7 | Responses of microbial activities and soil physical-chemical properties to the successional process of biological soil crusts in the Gurbantunggut Desert,Xinjiang显示文摘Biological soil crusts(BSCs) are capable of modifying nutrient availability to favor the establishment of biogeochemical cycles. Microbial activities serve as critical roles for both carbon and nutrient transformation in BSCs. However, little is known about microbial activities and physical-chemical properties of BSCs in the Gurbantunggut Desert, Xinjiang, China. In the present research, a sampling line with 1-m wide and 20-m long was set up in each of five typical interdune areas selected randomly in the Gurbantunggut Desert. Within each sampling line, samples of bare sand sheet, algal crusts, lichen crusts and moss crusts were randomly collected at the depth of 0–2 cm. Variations of microalgal biomass, microbial biomass, enzyme activities and soil physical-chemical properties in different succession of BSCs were analyzed. The relationships between microalgal biomass, microbial biomass, enzymatic activities and soil physical-chemical properties were explored by stepwise regression. Our results indicate that microalgal biomass, microbial biomass and most of enzyme activities increased as the BSCs developed and their highest values occurred in lichen or moss crusts. Except for total K, the contents of most soil nutrients(organic C, total N, total P, available N, available P and available K) were the lowest in the bare sand sheet and significantly increased with the BSCs development, reaching their highest values in moss crusts. However, pH values significantly decreased as the BSCs developed. Significant and positive correlations were observed between chlorophyll a and microbial biomass C. Total P and N were positively associated with chlorophyll a and microbial biomass C, whereas there was a significant and negative correlation between microbial biomass and available P. The growth of cyanobacteria and microorganism contributed C and N in the soil, which offered substrates for enzyme activities thus increasing enzyme activities. Probably, improvement in enzyme activities increased soil fertility and promoted the growth of cyanobacteria, eukaryotic algae and heterotrophic microorganism, with the accelerating succession of BSCs. The present research found that microalgal-microbial biomass and enzyme activities played important roles on the contents of nutrients in the successional stages of BSCs and helped us to understand developmental mechanism in the succession of BSCs. | BingChang ZHANG XiaoBing ZHOU YuanMing ZHANG | 2015 | Journal of Arid Land2015，7，1： | 23 |
| 8 | A novel method for purification of recombinant adeno-associated virus vectors on a large scale显示文摘A novel method for recombinant adeno-associ-ated virus (rAAV) purification on large scale is described. The method involves three steps, including chloroform treatment, PEG/NaCl precipitation and chloroform extraction. The whole procedure can be performed in four hours. Using this purification method, we can reproducibly obtain, from 4 × 109 of proviral cells cultured in roller bottles, purified rAAV-GFP stocks with titers of around 5×1013 particles/mL and purity greater than 95%. The infectious titers of the vector stocks were up to 2×1012 TU/mL, thus particle-to-infectivity rate was about 25. Under an electronic microscope, most rAAV particles appeared full and a few were in intermediate form. Empty particles were rarely seen. The purified rAAV-GFP stocks have been successfully used in in vitro and in vivo transfection experiments. Therefore, this new method offers a simple, rapid and cost-effective way for large-scale rAAV purification. | WU Xiaobing DONG Xiaoyan WU Zhijian CAO Hui NIU Dongbin QU Jianguo WANG Hong HOU Yunde | 2001 | Chinese Science Bulletin2001，46，6： | 21 |
| 9 | Developing land use scenario dynamics model by the integration of system dynamics model and cellular automata model显示文摘Modeling land use scenario changes and its potential impacts on the structure and function of the ecosystem in the typical regions are helpful to understanding the interactive mechanism between land use system and ecological system. A Land Use Scenario Dynamics (LUSD) model by the integration of System Dynamics (SD) model and Cellular Automata (CA) model is developed with land use scenario changes in northern China in the next 20 years simulated in this paper. The basic idea of LUSD model is to simulate the land use scenario de-mands by using SD model at first, then allocate the land use scenario patterns at the local scale with the considerations of land use suitability, inheritance ability and neighborhood effect by using CA model to satisfy the balance between land use scenario demands and supply. The application of LUSD model in northern China suggests that the model has the ability to reflect the complex behavior of land use system at different scales to some extent and is a useful tool for assessing the potential impacts of land use system on ecological system. In addition, the simulated results also indicate that obvious land use changes will take place in the farming-pastoral zone of northern China in the next 20 years with cultivated land and urban land being the most active land use types. | HE Chunyang, SHI Peijun, CHEN Jin, Li Xiaobing, PAN Yaozhong, LI Jing, LI Yuechen & LI Jinggang Key Laboratory of Environmental Change and Natural Disaster, Ministry of Education of China, Beijing Normal University College of Resources Science & Technology, Beijing Normal University, Beijing 100875, China | 2005 | Science China Earth Sciences2005，48，11： | 21 |
| 10 | Repurposing vitamin D for treatment of human malignancies via targeting tumor microenvironment显示文摘Tumor cells along with a small proportion of cancer stem cells exist in a stromal microenvironment consisting of vasculature, cancer-associated fibroblasts, immune cells and extracellular components.Recent epidemiological and clinical studies strongly support that vitamin D supplementation is associated with reduced cancer risk and favorable prognosis. Experimental results suggest that vitamin D not only suppresses cancer cells, but also regulates tumor microenvironment to facilitate tumor repression. In this review, we have outlined the current knowledge on epidemiological studies and clinical trials of vitamin D. Notably, wesummarized and discussed the anticancer action of vitamin D in cancer cells, cancer stem cells and stroma cells in tumor microenvironment, providing a better understanding of the role of vitamin D in cancer. We presently re-propose vitamin D to be a novel and economical anticancer agent. | Xu Wu Wei Hu Lan Lu Yueshui Zhao Yejiang Zhou Zhangang Xiao Lin Zhang Hanyu Zhang Xiaobing Li Wanping Li Shengpeng Wang Chi Hin Cho Jing Shen Mingxing Li | 2019 | Acta Pharmaceutica Sinica B2019，9，2： | 20 |

| 12 | Leaf N and P stoichiometry of 57 plant species in the Karamori Mountain Ungulate Nature Reserve,Xinjiang,China显示文摘Nitrogen(N) and phosphorus(P) are the major nutrients that constrain plant growth and development,as well as the structure and function of ecosystems.Hence,leaf N and P patterns can contribute to a deep understanding of plant nutrient status,nutrient limitation type of ecosystems,plant life-history strategy and differentiation of functional groups.However,the status and pattern of leaf N and P stoichiometry in N-deficiency desert ecosystems remain unclear.Under this context,the leaf samples from 57 plant species in the Karamori Mountain Ungulate Nature Reserve,eastern Junggar Desert,China were investigated and the patterns and interrelations of leaf N and P were comparatively analyzed.The results showed that the average leaf N concentration,P concentration,and N:P ratio were 30.81 mg/g,1.77 mg/g and 17.72,respectively.This study found that the leaf N concentration and N:P ratio were significantly higher than those of studies conducted at global,national and regional scales;however,the leaf P concentration was at moderate level.Leaf N concentration was allometrically correlated with leaf P and N:P ratio across all species.Leaf N,P concentrations and N:P ratio differed to a certain extent among plant functional groups.C_4 plants and shrubs,particularly shrubs with assimilative branches,showed an obviously lower P concentration than those of C_3 plants,herbs and shrubs without assimilative branches.Shrubs with assimilative branches also had lower N concentration.Fabaceae plants had the highest leaf N,P concentrations(as well as Asteraceae) and N:P ratio;other families had a similar N,P-stoichiometry.The soil in this study was characterized by a lack of N(total N:P ratio was 0.605),but had high N availability compared with P(i.e.the available N:P ratio was 1.86).This might explain why plant leaves had high N concentration(leaf N:P ratio>16).In conclusion,the desert plants in the extreme environment in this study have formed their intrinsic and special stoichiometric characteristics in relation to their life-history strategy. | TAO Ye WU Ganlin ZHANG Yuanming ZHOU Xiaobing | 2016 | Journal of Arid Land2016，8，6： | 18 |
| 13 | Soil Bacterial Communities Under Different Long-Term Fertilization Regimes in Three Locations Across the Black Soil Region of Northeast China显示文摘Although soil bacteria play critical roles in agro-ecosystems, the knowledge of their response to long-term fertilization across the black soil region of Northeast China is limited. In this study, we sequenced 16 S rRNA genes to assess the effects of four long-term fertilization regimes—non-fertilization(NoF), chemical fertilizer(CF), manure(M), and chemical fertilizer plus manure(CFM)—on soil properties and bacterial communities in three locations, the northern, middle, and southern parts, across the black soil region. Results showed that the influence of fertilization regimes on soil properties varied significantly among the three locations. Manure fertilization significantly increased microbial biomass carbon and relative abundance of copiotrophic bacteria. Principal component analysis(PCA)showed that the total bacterial communities were separated into three groups according to the sampling location despite long-term fertilization, and that soil pH was the most important factor in shifting bacterial communities. In addition, similar fertilization regimes resulted in different influences on bacterial community composition, and the most influential soil properties varied among the three locations. Our results highlighted that geographical separation was a more dominant factor affecting bacterial communities than fertilization, and that long-term similar fertilization regimes did not induce consistent changes in bacterial community composition in the black soil region. | HU Xiaojing LIU Junjie WEI Dan ZHU Ping CUI Xi'an ZHOU Baoku CHEN Xueli JIN Jian LIU Xiaobing WANG Guanghua | 2018 | Pedosphere2018，28，5： | 17 |
| 14 | Generation of a recombinant herpes simplex virus which can provide packaging function for recombinant adeno-associated virus显示文摘The generation of a recombinant HSV (rHSV) that can provide packaging function for rAAV production is described. A set of cosmids including cos48, cos28, cos6, cos14 and cos56, which represents the HSV-1 genome was used for generation of this rHSV. Rep and cap genes of AAV-2 were inserted into Xba Ⅰ site of UL2 gene on cos6, generating cos6-rcΔUL2. After being digested with Pac Ⅰ , cos6-rcΔUL2 and the other 4 cosmids were cotrans-fected into BHK-21 cells. The recombinant virus HSV1-rc/ΔUL2 carrying rep and cap genes was generated due to the homologous recombination of the 5 cosmids. The results showed that the existence of rep and cap genes on this rHSV was stable from passage to passage and the rHSV could support the packaging of rAAV either in cells transiently transfected with AAV vector or in stable cell line harboring AAV vector. Further modification of this rHSV and optimization of conditions involved in rAAV preparation may lead to a large-scale production of rAAV in the near future. | WU Zhijian, WU Xiaobing and HOU YundeState Key Laboratory for Molecular Virology and Genetic Engineering , Institute of Virology , Chinese Academy of Preventive Medicine , Beijing 100052, China Corresponding author | 1999 | Chinese Science Bulletin1999，44，8： | 15 |
| 15 | Estimation of carbon sinks in chemical weathering in a humid subtropical mountainous basin显示文摘The fluvial geochemistry of the mainstream and tributaries of the Zengjiang River was investigated,and the mass balance approach and deduction methods were used to estimate the uptake of atmospheric CO2 through rock chemical weathering.The results showed that the chemical runoff mainly consisted of HCO3-,Ca2+,Na+,and dissolved Si,and that silicate mineral weathering was significant,but carbonate mineral weathering was a minor source of dissolved loads in the Zengjiang River basin because of the low amount of interlayered carbonate rock strata in the catchment.The ion composition indicated that atmospheric CO2 was the primary erosive agent for rock chemical weathering in the Zengjiang River basin.The CO2 consumption fluxes caused by rock chemical weathering were(3.50-3.81) × 105 mol km-2 a-1,which is just lower than that in tropical and subtropical basalt and carbonate regions,and is much higher than that in temperate and cold-temperate regions,indicating that surficial chemical weathering processes in the humid and hot monsoon current influencing the low-middle latitude zone of the Northern Hemisphere constitutes a significant carbon sink in the global biogeochemical cycle. | TAO Zhen GAO QuanZhou WANG ZhenGang ZHANG ShengHua XIE ChenJi LIN PeiSong RUAN XiaoBing LI ShuHong MAO HaiRuo | 2011 | Chinese Science Bulletin2011，56，35： | 15 |
| 16 | Analysis of solid-liquid-gas interactions in landfilled municipal solid waste by a bio-hydro-mechanical coupled model显示文摘Based on first-order kinetics of hydrolysis process,biodegradation of municipal solid waste(MSW) is assumed to obey a first-order decay equation which can take the direct effect of water content on biodegradation into account.Hydraulic model is an unsaturated-saturated flow model using mass conservation equations for fluids.Mechanical compression of MSW is ex-pressed by a stress-age coupled compression model.Through above models,a one-dimensional(1-D) bio-hydro-mechanical coupled model is established to analyze solid-liquid-gas interactions in landfilled MSW.Values of all the model parameters for current typical Chinese MSW are determined.Numerical analysis of a hypothetical waste sample in a closed system shows that gas pressure and gas concentration is extremely large which might cause severe gas explosion problem.Total gas production is about 267.0 m3 per wet ton of fresh wastes.For another hypothetical landfilled MSW layer,the coupled model predicts a dis-sipation of gas pressure during passive gas collection process.Annual gas production is large at the beginning of biodegrada-tion,and then decreases with time.Surface settlement of the wastes increases quickly initially and then becomes stable with a compression strain of about 0.32 after 20 years. | CHEN YunMin XU XiaoBing ZHAN LiangTong | 2012 | Science China(Technological Sciences)2012，55，1： | 14 |
| 17 | The Interactions among DWARF10,Auxin and Cytokinin Underlie Lateral Bud Outgrowth in Rice显示文摘Previous studies have shown that DWARF10(D10) is a rice ortholog of MAX4/RMS1/DAD1,encoding a carotenoid cleavage dioxygenase and functioning in strigolactones/strigolactone-derivatives(SL) biosynthesis.Here we use D10-RNA interference(RNAi) transgenic plants similar to d10 mutant in phenotypes to investigate the interactions among D10,auxin and cytokinin in regulating rice shoot branching.Auxin levels in node 1 of both decapitated D10-RNAi and wild type plants decreased significantly,showing that decapitation does reduce endogenous auxin concentration,but decapitation has no clear effects on auxin levels in node 2 of the same plants.This implies that node 1 may be the location where a possible interaction between auxin and D10 gene would be detected.D10 expression in node 1 is inhibited by decapitation,and this inhibition can be restored by exogenous auxin application,indicating that D10 may play an important role in auxin regulation of SL.The decreased expression of most OsPINs in shoot nodes of D10-RNAi plants may cause a reduced auxin transport capacity.Furthermore,effects of auxin treatment of decapitated plants on the expression of cytokinin biosynthetic genes suggest that D10 promotes cytokinin biosynthesis by reducing auxin levels.Besides,in D10-RNAi plants,decreased storage cytokinin levels in the shoot node may partly account for the increased active cytokinin contents,resulting in more tillering phenotypes. | Shuying Zhang Gang Li Jun Fang Weiqi Chen Haipai Jiang Junhuang Zou Xue Liu Xianfeng Zhao Xiaobing Li Chengcai Chu Qi Xie Xiangning Jiang Lihuang Zhu | 2010 | Journal of Integrative Plant Biology2010，52，7： | 14 |
| 18 | Ductile deformation within Upper Himalaya Crystalline Sequence and geological implications,in Nyalam area,Southern Tibet显示文摘The South Tibet Detachment System(STDS) is a flat normal fault that separates the Upper Himalaya Crystalline Sequence(UHCS) below from the Tethyan Sedimentary Sequence(TSS) above.Timing of deformations related to the STDS is critical to understand the mechanism and evolution of the Himalaya collision zone.The Nyalam detachment(ND)(~86°E) locates in the middle portion of STDS(81°-89°E).Dating of deformed leucocratic dykes that are most probably syntectonic at different depth beneath the ND,allow us to constrain the timing of deformation.(1) Dyke T11N37 located ~3500 m structurally below the ND emplaced at 27.4± 0.2 Ma;(2) Dyke T11N32 located ~1400 m structurally below the ND emplaced at 22.0±0.3 Ma;(3) T11N25 located within the top to the north STD shear zone,~150 m structurally below the ND,emplaced at 17.1±0.2 Ma.Combining ND footwall cooling history and T11N25 deformation temperature,we indicate a probable onset of top to the north deformation at ~16 Ma at this location.These results show an upward younging of the probable timing of onset of the deformation at different structural distance below the ND.We then propose a new model for deformation migration below the ND with deformation starting by pure shear deformation at depth prior to ~27.5 Ma that migrates upward at a rate of ~ 0.3 mm/a until ~18 Ma when deformation switches to top to the north shearing in the South Tibet Detachment shear zone(STDsz).As deformation on the ND stops at 14-13 Ma this would imply that significant top to the North motion would be limited to less than 5 Ma and would jeopardize the importance of lower channel flow. | LIU XiaoBing LIU XiaoHan LELOUP P.H.

| 19 | Paleo-Tethyan Oceanic Crust Subduction in the Eastern Section of the East Kunlun Orogenic Belt:Geochronology and Petrogenesis of the Qushi'ang Granodiorite显示文摘The Qushi'ang granodiorite(QSG) is located at the central east of the ophiolitic melange belt in the East Kunlun Orogenic Belt(EKOB) in the northern margin of the Qinghai-Tibetan Plateau. LA-MC-ICP-MS zircon U–Pb dating suggests that the granodiorite and mafic microgranular enclaves(MMEs) crystallized 246.61±0.62 and 245.45±0.9 Ma ago, respectively. Granodiorite, porphyritic diorite, and MMEs are metaluminous and medium-K calk-alkaline series, with island-arc magma features, such as LILE enrichment and HFSE depletion. The porphyritic diorite has high Cr(13.50 ppm to 59.01 ppm), Ni(228.53 ppm to 261.29 ppm), and Mg~#(46–54). Granodiorite and porphyritic diorite have similar mineral compositions and evolved major and trace elements contents, particularly Cr and Ni, both of which are significantly higher than that in granites of the same period. The crystallization age of MMEs is close to that of granodiorite, and their major and trace elements contents are in-between porphyritic diorite and granodiorite. The results suggest that the original mafic magma, which was the product of mantle melting by subduction process, intruded into the lower crust(Kuhai Rock Group), resulting in the formation of granodiorite. Countinous intrusion of mafic magma into the unconsolidated granodiorite formed MMEs and porphyritic diorite. The granodiorite reformed by late-stage strike-slip faulting tectonic event indicates that the strike-slip fault of Middle Kunlun and the collision of the Bayanhar block with East Kunlun were later than 246 Ma. Therefore, the formation of the QSG not only indicates the critical period of evolution of East Kunlun but also represents the tectonic transition from oceanic crust subduction to slab breaking. | CHEN Guochao PEI Xianzhi LI Ruibao LI Zuochen LIU Chengjun CHEN Youxin PEI Lei WANG Meng LI Xiaobing | 2017 | Acta Geologica Sinica(English Edition)2017，91，2： | 14 |
| 20 | Growth and Common Prosperity in China显示文摘This paper introduces a decomposition method that quantifies the contributions to common prosperity of labor market performance and social policies and extends the idea of shared prosperity to a new measure of inequity in opportunities.The resulting common prosperity indices and opportunity equality indices are then applied to five waves of the Chinese Household Income Project data from 1988 to 2018.This paper shows that the labor market performance and social policies have been improving over the last 30 years and have helped China move towards common prosperity for everyone.The indices developed in this paper allow us to quantify the extent of shared prosperity that a country has achieved and to carry out empirical studies on which policy is working and which is not.It can also help us identify the fundamental causes of inequality and aid us in achieving equality in opportunity among all members of society. | Nanak Kahwani Xiaobing Wang Ning Xue Peng Zhan | 2022 | China & World Economy2022，30，1： | 13 |
