| 1 | 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 |
| 2 | 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 |
| 3 | 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 |
| 4 | 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 |
| 5 | 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.

| 6 | Late Eocene pollen records and palaeoenvironmental changes in northern Tibetan Plateau显示文摘The Eocene palaeovegetation landscape and palaeoclimate reconstructed from the pollen records in the Jiuquan Basin, northwest China provide some important information on the early uplift of the Tibetan Plateau and the origin and evolution of the aridification in northwest China. The records show the arid-semiarid scrubs with open forest palynofloras controlled by the subtropical high existed in northwest China during the 40.2-33.4 Ma. Four pollen assemblages are found: Nitrariadites-Cheno-podipollis-Pinaceae assemblage (40.2-37.9 Ma) is followed by Chenopodipollis-Nitrariadites assemblage (37.9-34.6 Ma), Pinuspollenites & Abietineaepollenites-Chenopodipollis assemblage (34.6-33.9 Ma), and Chenopodipollis-Nitrariadites assemblage (33.9-33.4 Ma). The percentage of thermophilic types is in anti-correlation with that of the dry types, which means the palaeoclimate is relatively warmwet or cold-dry during most of that time. Such aridity may be related to the water vapor reduction and the planetary wind system movement northward in response to the cooling caused by small-ephemeral icesheets. | MIAO YunFa FANG XiaoMin SONG ZhiChen WU FuLi HAN WenXia DAI Shuang SONG ChunHui | 2008 | Science China Earth Sciences2008，51，8： | 10 |
| 7 | Magnetic properties of surface soils across the southern Tarim Basin and their relationship with climate and source materials显示文摘The magnetic susceptibility (χ) of surface soils on the Chinese Loess Plateau (CLP) has strong positive correlation with mean annual precipitation.It is widely accepted that ultrafine magnetite/maghemite grains produced during pedogenesis are responsible for the enhancement of χ,and loess χ on the CLP has been widely used as a proxy for the intensity of the East Asian summer monsoon.However,few works have investigated mechanisms for the enhancement of χ in the case of surface aeolian sediments in westerly-dominated inland China,north of the Tibetan Plateau.Here detailed rock magnetism and grain size studies of 49 surface samples taken across the southern Tarim Basin for different rainfall/temperature/altitude conditions are presented.The results show that samples taken from desert have the lowest χ values and that χ of loessic sand and loess samples decreases with increasing altitude.In addition,the rock magnetism studies suggest that the magnetic properties of surface soils across the southern Tarim Basin are mainly controlled by the concentration of coarse aeolian ferrimagnetic minerals.The contribution of ultrafine pedogenically produced magnetic grains to χ is very limited. | ZAN JinBo FANG XiaoMin NIE JunSheng YANG ShengLi SONG ChunHui DAI Shuang | 2011 | Chinese Science Bulletin2011，56，3： | 5 |
| 8 | The effect of different layered materials on the tribological properties of PTFE composites显示文摘Two-dimensional(2D)lamellar materials have unique molecular structures and mechanical properties,among which molybdenum disulfide(MoS2)and graphitic carbon nitride(g-C3N4)with different interaction forces served as reinforcing phase for polytetrafluoroethylene(PTFE)composites in the present study.Thermal stability,tribological and thermomechanical properties of composites were comprehensively investigated.It was demonstrated that g-C3N4 improved elastic deformation resistance and thermal degradation characteristics.The addition of g-C3N4 significantly enhanced anti-wear performance under different loads and speeds.The results indicated that PTFE composites reinforced by g-C3N4 were provided with better properties because the bonding strength of g-C3N4 derived from hydrogen bonds(H-bonds)was stronger than that of MoS2 with van der Waals force.Consequently,g-C3N4 exhibited better thermomechanical and tribological properties.The result of this work is expected to provide a new kind of functional filler for enhancing the tribological properties of polymer composites. | Song LI Chunjian DUAN Xiao LI Mingchao SHAO Chunhui QU Di ZHANG Qihua WANG Tingmei WANG Xinrui ZHANG | 2020 | Friction2020，8，3： | 5 |
| 9 | Sedimentary Conditions of Evaporites in the Late Jurassic Xiali Formation,Qiangtang Basin:Evidence from Geochemistry Records显示文摘The Qiangtang Basin(QB), located in the central Tibetan Plateau, is a Jurassic marine basin and one of the most important prospective salt resource belts in China. In recent decades, many outcrops of gypsiferous bed have been found in the Jurassic marine strata in the basin. Salt springs with abnormally high sodium(Na^+) contents had been identified in the Late Jurassic Xiali Formation(Fm.) in the basin in the last years. However, to date, no potash or halite deposits have been identified in the QB. Gypsum outcrops and salt springs are very important signs in the investigation of halite and potash deposits. Therefore, the Xiali Fm. is a potentially valuable layer to evaluate for the possible presence of halite and potash deposits in the basin. However, few studies have explored the formation conditions of evaporites in the unit. Here, we present detailed geochemical records from the Yanshiping section related to the study of the formation conditions of evaporites in the Xiali Fm. of the QB. Climate proxies based on the obviously increased anion concentrations of SO_4(2-) and Cl^- and the significant correlation coefficients of Ca2+-SO42-(R = 0.985) and Na^+-Cl^-(R = 0.8974) reveal that the upper member of the Xiali Fm.(the upper Xiali Fm.) formed under an arid climate and evolved into the sulfate phase or early chloride phase. Provenance proxies based on the obviously increased K^+ and Na^+ ion concentrations and the significant correlation coefficient of Na^+-Cl^-(R = 0.8974) suggest that the upper Xiali Fm. featured optimal provenance conditions for the possible formation of halite deposits. The regression and the semi-closed tidal flat environment in the upper Xiali Fm. were favorable for the formation of potash and halite deposits. The low Mg^(2+) /Ca^(2+) values(mean value = 1.82) and significant Na^+-Cl^- correlation coefficient(R = 0.8974) also suggest that the upper Xiali Fm. is the layer most likely to contain potential halite deposits. In addition, the macroscopic correlations of tectonism, provenance, paleoclimate, saliferous strata and sedimentary environment between the QB and the adjoining Amu Darya Basin in Central Asia reveal that the two basins shared similar geologic settings that were favorable for the formation of evaporites during the Late Jurassic. Therefore, the upper Xiali Fm. is a valuable layer to explore for halite deposit and may be potentially valuable in the future exploration for potash deposits in the QB. | SONG Chunhui ZENG Yongyao YAN Maodu FANG Xiaomin FENG Ying PAN Jiaqiu LIU Xifang MENG Qingquan HU Chunhua ZHONG Sirui | 2017 | Acta Geologica Sinica(English Edition)2017，91，1： | 4 |
| 10 | Identification of a locus associated with genic male sterility in maize via EMS mutagenesis and bulked-segregant RNA-seq显示文摘Genic male sterility(GMS) is one of the most important resources for exploiting heterosis in crop breeding, so that identifying genomic loci regulating GMS is desirable. However, many regulatory genes controlling GMS have not yet been characterized in maize, owing partly to a lack of genetic materials. We generated a recessive male-sterile maize mutant in the Jing 724 genetic background via ethyl methanesulfonate treatment, and found the male sterility to be due to a single gene mutation. Bulk-segregant RNA sequencing of three replicates indicated that one genomic region located at the end of chromosome 4 was associated with the observed mutant phenotype. Among genes with nonsynonymous mutations,Zm00001 d053895(bHLH51) showed abolished expression in the sterile bulks and was annotated as a bHLH transcription factor orthologous to Arabidopsis AMS, suggesting an association with the male sterility of the mutant. Kompetitive Allele-Specific PCR assays further validated the exclusive correlation of male sterility with the single C-to-T mutation in the fifth exon. The new maize mutant and the potential SNP locus provide novel genetic material for investigating the molecular mechanism underlying tapetal development and may facilitate the improvement of hybrid production systems. | Zi Shi Wen Ren Yanxin Zhao Xiaqing Wang Ruyang Zhang Aiguo Su Shuai Wang Chunhui Li Jiarong Wang Shuaishuai Wang Yunxia Zhang Yulong Ji Wei Song Jiuran Zhao | 2021 | The Crop Journal2021，9，6： | 4 |
| 11 | Association oftransforming growth factor-β1 gene variants with risk of coal workers'pneumoconiosis显示文摘Objective:The aim of this case-control study was to explore whether five tagging single nucleotide polymorphisms(tSNPs)within the transforming growth factor-β1(TGF-β1)gene were involved in manifestation of inflammatory and fibrotic processes associated with coal workers'pneumoconiosis(CWP).Methods:The study included 508 CWP patients and 526 controls who were underground coal miners from Xuzhou Mining Business Group.Five tSNPs were selected from the HapMap and detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method.Results:The single SNP analysis showed that the genotype frequencies of SNP2(rs1800470,+869T/C,extron 1)and SNP5(rs11466345,intron 5)in CWP cases were sig- nificantly different from those in controls.Multivariate logistic regression analysis revealed that SNP2(rs1800470) CC genotype was associated with decreased risk of CWP(OR=0.50,95%CI=0.32-0.78),which was evident among subgroups of those never smoke(OR=0.40,95%CI=0.24-0.66),cases with stageⅡ(OR=0.41,95%CI =0.22-0.76)and exposure period(<28 y:OR=0.54,95%CI=0.31-0.95;≥28 y:OR=0.52,95%CI=0.32-0.96). However,the SNP5(rs11466345)GG genotype was associated with an increased risk of CWP(OR=2.5,95%CI =1.36-4.57),and further stratification analysis showed that the risk of CWP was increased in both smoking and nonsmoking groups,shorter and longer exposure groups,while the risk of CWP was only increased in patients with stageⅠandⅡ.Conclusion:This study suggests that TGF-β1 polymorphisms may contribute to susceptibility of CWP. | Haiyang Qian Zhifang Song Meilin Wang Xiaomin Jia Aiping Li Ye Yang Lianlian Shen Shasha Wang Chunhui Ni Jianwei Zhou | 2010 | The Journal of Biomedical Research2010，24，4： | 3 |
| 12 | Neodymium-doped Yttrium Aluminum Garnet Transparent Laser Ceramics Prepared by Co-precipitation Method显示文摘Transparent polycrystalline neodymium-doped yttrium aluminum garnet ceramics (Nd∶YAG) with better chemical stability, excellent optical and high temperature mechanical property is becoming a new laser host material. The Nd∶YAG precursor powders with loosely dispersed, slightly agglomerated and YAG cubic crystal phase were synthesized at 1100 ℃ by the co-precipitation method combined with the reverse strike, using Nd2O3, Y2O3, Al(NO3)3·9H2O and NH4HCO3 as raw materials, (NH4)2SO4 as electrical stabilizer, TEOS as sintering additive. The Nd∶YAG transparent ceramics were fabricated after being sintered at 1700 ℃ in vacuum for 5 h. The Nd∶YAG ceramic materials were characterized by the TG-DTA, XRD, FT-IR, TEM, FT-PL and FEG-ESEM. The results show that the precursor powders are amorphous at 800 ℃, the large amount YAlO3(YAP) and tiny amout Y3Al5O 12(YAG) appear when the calcination temperature is 890 ℃ and the YAP hexagonal crystal phase transforms to YAG cubic crystal phase at 1012 ℃. There are agglomerations in the precursor powders resulting from the high calcination temperature and the agglomerates link together, but as a whole the particles distribute homogeneously. The lasing wavelength of (Nd 0.01Y 0.99)3Al5O 12 transparent ceramics is 1.065 μm and there exists a slight red-shift compared to the single crystal with the same chemical composition. With the optical wavelength increasing, the transmittance of (Nd 0.01Y 0.99)3Al5O 12 raises gradually and the optical transmittance is about 45% in the visible light and 58% in the infrared light. | Su Chunhui Song Qiong Zhang Huashan Zhang Hongbo Hou Zhaoxia Shao Jing | 2006 | Journal of Rare Earths2006，24，1： | 2 |

| 15 | Remodeling tumor immunosuppressive microenvironment via a novel bioactive nanovaccines potentiates the efficacy of cancer immunotherapy显示文摘The clinical outcomes of cancer nanovaccine have been largely impeded owing to the low antigen-specific T cell response rate and acquired resistance caused by the immunosuppressive tumor microenvironment(TME).Here,we reported a tumor acidity-responsive nanovaccine to remodel the immunosuppressive TME and expand the recruitment of tumor infiltrating lymphocytes(TILs)using hybrid micelles(HM),which encapsulated colony stimulating factor 1 receptor(CSF1-R)inhibitor BLZ-945 and indoleamine 2,3-dioxygenase(IDO)inhibitor NLG-919 in its core and displayed a model antigen ovalbumin(OVA)on its surface(denoted as BN@HM-OVA).The bioactive nanovaccine is coated with a polyethylene glycol(PEG)shell for extending nanoparticle circulation.The shell can be shed in response to the weakly acidic tumor microenvironment.The decrease in size and the increase in positive charge may cause the deep tumor penetration of drugs.We demonstrated that the bioactive nanovaccine dramatically enhance antigen presentation by dendritic cells(DCs)and drugs transportation into M1-like tumor-associated macrophages(TAMs)and tumor cells via size reduction and increasing positive charge caused by the weakly acidic TME.Such bioactive nanovaccine could remodel the immunosuppressive TME into an effector T cells favorable environment,leading to tumor growth inhibition in prophylactic and therapeutic E.G7-OVA tumor models.Furthermore,combining the bioactive nanovaccine with simultaneous anti-PD-1 antibody treatment leads to a long-term tumor inhibition,based on the optimal timing and sequence of PD-1 blockade against T cell receptor.This research provides a new strategy for the development of efficient cancer immunotherapy. | Xiaoxue Xie Yi Feng Hanxi Zhang Qingqing Su Ting Song Geng Yang Ningxi Li Xiaodan Wei Tingting Li Xiang Qin Shun Li Chunhui Wu Xiaojuan Zhang Guixue Wang Yiyao Liu Hong Yang | 2022 | Bioactive Materials2022，7，10： | 1 |

| 18 | New insights on the age of the Mengyejing Formation in the Simao Basin,SE Tethyan domain and its geological implications显示文摘Knowledge on the origin and mechanism of the large potash formation in the southeast Tethyan tectonic domain are still under debate,one of which mainly due to the controversial ages of the potash-bearing strata.Here we present a detailed detrital zircon U-Pb geochronologic-magnetostratigraphic study of the potash-bearing Mengyejing(MYJ)Formation(Fm)from the Simao Basin.948 paleomagnetic cores and 4 detrital zircon U-Pb samples were collected from a 932-m thick Jiangcheng section.Thermal demagnetization isolated 857 primary characteristic remnant magnetization(ChRM)directions,indicated by positive reversals and fold tests and petrologic examinations.Seven normal and seven reversed polarity zones were identified and correlated well with chrons C27r to C34n of the geomagnetic polarity timescale(GPTS2012),yielding the first known age sequence of>112 to~63 Ma for the MYJ Fm.The ages for the potash bearing strata in the Simao commenced~20 Ma earlier than those in the adjacent Khorat basins,opposite to the traditional viewpoint that the former would rather correspond to the middle and lower parts of the latter.Given the paleogeographic reconstruction of likely a pan-Simao-Khorat basin during the Cretaceous,~85 Ma would be another important potential period for future potash exploration in the Simao Basin. | Maodu YAN Dawen ZHANG Xiaomin FANG Weilin ZHANG Chunhui SONG Chenglin LIU Jinbo ZAN Miaomiao SHEN | 2021 | Science China Earth Sciences2021，64，2： | 1 |
