| 3 | The Sequence of Magmatic-Tectonic Events and Orogenic Processes of the Yanshan Belt, North China显示文摘This paper emphasizes that the interactive constraints of geology and isotopic dating is the best approach to construct the geological event sequence, and has compiled 106 data of reasonable isotopic ages for the igneous rocks of the Yanshan belt. We propose a sequence of mgmatic-tectonic events in the Jurassic-Cretaceous Yanshan orogen of North China. Five orogenic episodes are divided, (1) pre-and initial orogenic episode (Early Jurassic); (2) early orogenic episode (Middle Jurassic); (3) peak orogenic episode (Late Jurassic); (4) late orogenic episode (early Early Cretaceous),and (5) post-orogenic episode. Each episode is a short cycle, all of the orogenic processes construct a longer cycle, and they, in general, followed a counter-clockwise (ccw) PTt path. Finally, it is suggested that the Yanshanian movement was so intensive that the magmatism and tectonic deformation had involved all the lithosphere thickness and the lateAchaean-formed cratonic lithosphere had been significantly reworked. | DENG Jinfu, SU Shangguo, MO Xuanxue, ZHAO Guochun, XIAO Qinghiu, JI Guangyi,QIU Ruizhao, ZHAO Hailing, LUO Zhaohua, WANG Yang and LIU Cui China University of Geosciences, Beijing 100083 and Key Laboratory of Lithospheric Tectonics and Lithoprobe Techniques, Ministry of Education of China | 2004 | Acta Geologica Sinica(English Edition)2004,78,1: | 35 |
| 4 | Quality analysis of commercial samples of Ziziphi spinosae semen(suanzaoren) by means of chromatographic fingerprinting assisted by principal component analysis显示文摘Due to the scarcity of resources of Ziziphi spinosae semen(ZSS), many inferior goods and even adulterants are generally found in medicine markets. To strengthen the quality control, HPLC fingerprint common pattern established in this paper showed three main bioactive compounds in one chromatogram simultaneously. Principal component analysis based on DAD signals could discriminate adulterants and inferiorities. Principal component analysis indicated that all samples could be mainly regrouped into two main clusters according to the first principal component(PC1, redefined as Vicenin II)and the second principal component(PC2, redefined as zizyphusine). PC1 and PC2 could explain 91.42%of the variance. Content of zizyphusine fluctuated more greatly than that of spinosin, and this result was also confirmed by the HPTLC result. Samples with low content of jujubosides and two common adulterants could not be used equivalently with authenticated ones in clinic, while one reference standard extract could substitute the crude drug in pharmaceutical production. Giving special consideration to the well-known bioactive saponins but with low response by end absorption, a fast and cheap HPTLC methodfor quality control of ZSS was developed and the result obtained was commensurate well with that of HPLC analysis. Samples having similar fingerprints to HPTLC common pattern targeting at saponins could be regarded as authenticated ones. This work provided a faster and cheaper way for quality control of ZSS and laid foundation for establishing a more effective quality control method for ZSS. | Shuai Sun Hailing Liu Shunjun Xu Yuzhen Yan Peishan Xie | 2014 | Journal of Pharmaceutical Analysis2014,4,3: | 17 |

| 6 | Existence of Qiongnan suture zone on the north margin of South China Sea显示文摘This paper aims to explore whether paleo-suture zone exists in the pre-Cenozoic basement of South China Sea (SCS). By taking advantage of integrated geophysical surveying data, including multi-channel reflection seismicity, oceanic bottom seismicity, gravity and magnetic data as well as paleomagnetism and drilling information, a comprehensive analysis on sedimentary stratigraphy, seismic stratigraphy, magmatic and metamorphic petrology, geochemistry, gravity study, magnetics, paleogeomagnetics as well as geotectonics was carried out, and the results clearly indicate that a pre-Cenozoic suture zone, i.e. “Qiongnan (south Hainan Island) suture zone”, does exist on the north margin of SCS. This suture zone starts in the west from the Jiusuo-Lingshui fault zone in the south of Hainan Island, extends eastward across the continental slope to the north of SCS, and links with Shoufeng fault in Taiwan. It is inferred that the Qiongnan suture zone was sutured approximately in Indosinian (Triassic) Epoch and is actually the vestige of “Qiongnan ocean basin”, the extension of the main paleo-Tethys ocean basin in SCS. The formation of Qiongnan suture zone marked the collision-accretion of the Qiongnan Block toward the Qiongzhong Block. The Qiongnan suture zone is linked to the west with the southward extension of the principal suture zone of the Paleo-Tethys at Bitu-Changning-Menglian-Bentong-Raub, across the southern segment of the Red River-East Vietnam-Wanna strike-slip fault zone, and connected to the east with the suture zone emplaced into the south margin of the Oki-Hida Pre-Jurassic terranes in southwest Japan, across the northerni2 e segment of the Manila trench fault zone in the northeast side of Taiwan Island. The discovery of this suture zone is believed to be potentially significant toward study of the pre-Cenozoic geotectonic pattern of SCS, the temporal and spatial distribution of the east paleo-Tethys structural domain in SCS and the relationship of recombination and superimposition between the east paleo-Tethys structural domain and the west Pacific structural domain, in addition to the oil/gas geological potentials in the pre-Cenozoic marine vestige-superimposed basin in the study area. | LIU Hailing YAN Pin LIU Yingchun DENG Hui | 2006 | Chinese Science Bulletin2006,51,B12: | 12 |
| 7 | The Cenozoic activities of Yangjiang-Yitongdong Fault: insights from analysis of the tectonic characteristics and evolution processes in western Zhujiang(Pearl) River Mouth Basin显示文摘The Yangjiang-Yitongdong Fault (YJF) is an important NW-trending regional fault, which divides the Zhujiang (Pearl) River Mouth Basin (ZRMB) into western and eastern segments. In Cenozoic, the northern continental margin of the South China Sea (SCS) underwent continental rifting, breakup, seafloor spreading and thermal subsidence processes, and the Cenozoic activities of YJF is one part of this series of complex processes. Two long NW-trending multichannel seismic profiles located on both sides of the YJF extending from the continental shelf to Continent-Ocean Boundary (COB) were used to study the tectonic and sedimentary characteristics of western ZRMB. Using the 2D-Move software and back-stripping method, we constructed the balance cross-section model and calculated the fault activity rate. Through the comprehensive consideration of tectonic position, tectonic evolution history, featured structure, and stress analysis, we deduced the activity history of the YJF in Cenozoic. The results showed that the YJF can be divided into two segments by the central uplift belt. From 65 Ma to 32 Ma, the YJF was in sinistral motion as a whole, inherited the preexisting sinistral motion of Mesozoic YJF, in which, the southern part of YJF was mainly in extension activity, controlling the formation and evolution of Yunkai Low Uplift, coupled with slight sinistral motion. From 32 Ma to 23.8 Ma, the sinistral motion in northern part of YJF continued, while the sinistral motion in southern part began to stop or shifted to a slightly dextral motion. After 23.8 Ma, the dextral motion in southern part of YJF continued, while the sinistral motion in northern part of YJF gradually stopped, or shifted to the slightly dextral motion. The shift of the YJF strike-slip direction may be related to the magmatic underplating in continent-ocean transition, southeastern ZRMB. According to the analysis of tectonic activity intensity and rift sedimentary structure, the activities of YJF in Cenozoic played a regulating role in the rift extension process of ZRMB. | Yuhan Li Rongwei Zhu Hailing Liu Xuelin Qiu Haibo Huang | 2019 | Acta Oceanologica Sinica2019,38,9: | 10 |
| 8 | On the Kinematic Characteristics and Dynamic Process of Boundary faults of the Nansha Ultra-crust Layer-Block显示文摘The Nansha ultra-crust layer-block is confined by ultra-crustal boundary faults of distinctive features, bordering the Kangtai-Shuangzi-Xiongnan extensional faulted zone on the north, the Baxian-Baram-Yoca-Cuyo nappe faulted zone on the south, the Wan’an-Natuna strike-slip tensional faulted zone on the west and the Mondoro-Panay strike-slip compressive faulted zone on the east. These faults take the top of the Nansha asthenosphere as their common detachmental surface. The Cenozoic dynamic process of the ultra-crust layer-block can be divided into four stages: K2-E21, during which the northern boundary faults extended, this ultra-crust layer-block was separated from the South China-Indosinian continental margin, the Palaeo-South China Sea subducted southwards and the Sibu accretion wedge was formed; E22-E31, during which the Southwest sub-sea basin extended and orogeny was active due to the collision of the Sibu accretion wedge; E32-N11, during which the central sub-sea basin extended, the Miri | LIU Hailing SUN Yan GUO Lingzhi SHU Liangshu YANG Shukang ZHOU Di ZHANG Yixiang | 1999 | Acta Geologica Sinica(English Edition)1999,73,4: | 9 |
| 9 | 中国近地面臭氧来源解析研究综述显示文摘近年来,在实施了一系列较为严格的空气污染控制措施后,中国的PM2.5污染已得到明显改善,但近地面臭氧污染问题却日益凸显,尤其是在一些发达的城市群,如京津冀,长三角,珠三角和四川盆地地区。鉴于臭氧生成的复杂性及其与前体物的非线性关系,准确定位臭氧及其前体物的来源是制定经济高效的臭氧污染控制策略的重要前提。本文总结了近20年来国内外已发表文章中关于中国臭氧来源(包括区域和行业来源)的主要方法 (包括基于观测的方法和基于排放的方法)和结论,希望能为中国臭氧污染的全面了解和空气污染防治政策的制定提供可靠的参考。 | LIU Hailing ZHANG Meigen HAN Xiao | 2020 | Atmospheric and Oceanic Science Letters2020,13,5: | 9 |
| 10 | MiR156 regulates anthocyanin biosynthesis through SPL targets and other microRNAs in poplar显示文摘Anthocyanins biosynthesized from the flavonoid pathway are types of pigments that are involved in the protection of poplar from biotic and abiotic stresses.Previous researchers studying anthocyanin-related transcription factors and structural genes in poplar have made significant discoveries.However,little is known about the regulatory role of microRNAs in anthocyanin biosynthesis in poplar.Here,we overexpressed miR156 in poplar to study the comprehensive effects of the miR156-SPL module on the biosynthesis of anthocyanins.Small RNA sequencing analysis revealed 228 microRNAs differentially expressed in transgenic poplar plants with dramatically increased miR156 levels.Furthermore,integrated microRNAomic and transcriptomic analysis suggested that two microRNAs,miR160h,and miR858,have the potential to affect anthocyanin accumulation in poplar by regulating auxin response factors and MYB transcription factors,respectively.Additionally,the accumulation of miR160h and miR858 displayed a positive correlation with miR156 levels,suggesting a possible interaction between the miR156-SPL module and these microRNAs in poplar.Last,metabolomics analysis revealed that the levels of anthocyanins,flavones,and flavonols were substantially elevated in transgenic poplar plants overexpressing miR156 compared with the wild type,whereas the total lignin content was reduced in the transgenic plants.Taken together,our results indicate that miR156 can fine tune the anthocyanin biosynthetic pathway via multiple factors,including microRNAs,transcription factors,and the levels of structural genes,in poplar.This provides additional clues for understanding the complex regulatory network of anthocyanin biosynthesis in woody plants. | Yamei Wang Wenwen Liu Xinwei Wang Ruijuan Yang Zhenying Wu HanWang LeiWang Zhubing Hu Siyi Guo Hailing Zhang Jinxing Lin Chunxiang Fu | 2020 | Horticulture Research2020,7,1: | 9 |
| 11 | Effects of dietary vitamin E on muscle vitamin E and fatty acid content in Aohan fine-wool sheep显示文摘value for consumers. Several laboratories have evaluated the effects of vitamin E on the fatty acid(FA) composition of muscle in sheep. However, little information is available on wool sheep, even though wool sheep breeds are an important source of mutton, especially in northern China where sheep are extensively farmed. The present study was designed to address the effects of vitamin E on muscle FA composition in male Aohan fine-wool sheep. Methods: Forty-two male Aohan fine-wool lambs(5 mo old) with similar initial body weight were randomly divided into seven groups and fed diets supplemented with 0(control group), 20, 100, 200, 1,000, 2,000, or 2,400 IU/sheep/d vitamin E for 12 mo. Three lambs from each group were slaughtered to measure vitamin E and FA content in the longissimus lumborum(LL) and gluteus medius(GM) muscles. Results: Vitamin E concentrations in the LL and GM increased significantly after 12 mo of vitamin E supplementation(P < 0.05). However, this increase did not occur in a dose-dependent manner because the muscle vitamin E concentration was highest in the 200 IU/sheep/d group. Dietary vitamin E supplementation also caused a significant reduction in SFA content and an increase in monounsaturated FA(MUFA) content in the LL and GM(P < 0.05). All six doses of vitamin E significantly increased cis9 trans11-conjugated linoleic acid(c9t11-CLA) content in the LL compared with the control group(P < 0.05). Conclusions: Dietary supplementation with vitamin E increased muscle vitamin E content and improved the nutritional value of mutton by decreasing SFA content and increasing MUFA and c9t11-CLA contents in Aohan fine-wool sheep. These effects were greatest in sheep fed a diet containing 200 IU/sheep/d vitamin E. | Kun Liu Suyun Ge Hailing Luo Dubing Yue Leyan Yan | 2013 | Journal of Animal Science and Biotechnology2013,4,4: | 6 |
| 12 | Nitrogen uptake and transfer in broad bean and garlic strip intercropping systems显示文摘Utilization and transfer of nitrogen(N)in a strip intercropping system of garlic(Allium sativum L.)and broad bean(Vicia faba L.)have been investigated rarely.The objectives of this study were to quantify N uptake and utilization by intercropped broad bean and garlic and determine the magnitude of N transfer from broad bean to garlic.Field and pot trials were carried out in the Erhai Lake Basin in China using ^(15)N tracer applied to the soil or injected into broad bean plants.Strip intercropping of garlic and broad bean increased N absorption(47.2%)compared with sole crop broad bean(31.9%)or sole crop garlic(40.7%)and reduced soil residual N.Nearly 15%of ^(15)N injected into petioles of broad bean intercropped with garlic was recovered in garlic at harvest,suggesting that N could be transferred from broad bean to strip intercropped garlic.The findings provide a basis for evaluating legumes’role in optimizing N fertilization when intercropped with non-legumes. | TANG Qiu-xiang Haile Tewolde LIU Hong-bin REN Tian-zhi JIANG Ping-an ZHAI Li-mei LEI Bao-kun LIN Tao LIU En-ke | 2018 | Journal of Integrative Agriculture2018,17,1: | 5 |
| 13 | The study on the mechanical properties of PU/MF double shell self-healing microcapsules显示文摘The self-healing microcapsules can be buried in the coating to improve the anticorrosive ability.In this paper,self-healing microcapsules of polyurea(PU)/melamine resin(MF)double shell were prepared by in-situ polymerization and interfacial polymerization with isocyanate as the core material.Scanning electron microscope was used to observe the microcapsule morphology.The structures of microcapsules prepared with different chain extenders were characterized by Fourier transform infrared spectroscopy.The micromanipulation system was used to loading–holding,loading–unloading and loading to rupture individual microcapsules,so as to explore the mechanical properties of microcapsules.The Young’s modulus corresponding to microcapsules was calculated by mathematical model fitting.The self-healing properties of microcapsule coating were characterized by optical microscope.The experimental results showed that the microcapsule shell prepared under optimized conditions had a complete morphology and good mechanical properties.The microcapsule was in the elastic deformation stage under small deformation,and the plastic deformation stage under large deformation.The Young’s modulus range of microcapsules was 9.29–14.51 MPa,and the corresponding Young’s modulus could be prepared by adjusting the process.The surface crack of the coating containing microcapsule could heal itself after48 h in a humid environment. | Guohao Du Jianfeng Hu Jianhui Zhou Guangwu Wang Shengli Guan Hailing Liu Man Geng Chuang Lv Yaoqiang Ming Jinqing Qu | 2020 | Chinese Journal of Chemical Engineering2020,28,5: | 4 |
| 14 | Enhancement of transfection efficiency for HeLa cells via incorporating arginine moiety into chitosan显示文摘Arginine-rich peptides have attracted considerable attention due to their distinct internalization mechanism. It was reported that arginine and guanidino moieties were able to translocate through cell membranes and played a critical role in the process of membrane permeation. In this work, arginine was conjugated to the backbone of chitosan to form a novel chitosan derivative, arginine modified chitosan (Arg-CS). Arg-CS/DNA complexes were prepared according to the method of coacervation process. The physicochemical properties of Arg-CS and Arg-CS/DNA complexes were characterized and the transfection activity and efficiency mediated by Arg-CS/DNA complexes were investigated taking HeLa cells as target cells. Arg-CS was characterized by FTIR and 13C NMR. Arg-CS/DNA polye- lectrolyte complexes were investigated by agarose gel retardation, dynamic light scattering (DLS) and atomic force microscopy (AFM). The results revealed that the Arg-CS/DNA complexes started to form at N/P ratio of 2:1, and the size of particles varied from 100 to 180 nm. The cytotoxicity of Arg-CS and their complexes with plasmid DNA were determined by MTT assay for HeLa cells, and the results suggested that Arg-CS/DNA complexes were slightly less toxic than Arg-CS. Moreover, the derivative alone and their complexes showed significantly lower toxicity than PEI and PEI/DNA complexes, respectively. Taking HeLa cells as target cells and using pGL3-control as reporter gene, the luciferase expression mediated by Arg-CS was greatly enhanced to about 100 folds compared with the luciferase expression mediated by chitosan at different pH media. These results suggest that Arg-CS is a promising candi- date as a safe and efficient vector for gene delivery and transfection. | ZHU DunWan ZHANG HaiLing BAI JinGen LIU WenGuang LENG XiGang SONG CunXian YANG Jian LI XiaoWei JIN Xu SONG LiPing LIU LanXia LI XiuLan ZHANG Yang YAO KangDe | 2007 | Chinese Science Bulletin2007,52,23: | 4 |
| 15 | Layer-block tectonics of Cenozoic basements and formation of intra-plate basins in Nansha micro-plate, southern South China Sea显示文摘Layer-block tectonics (LBT) concept, with the core of pluralistic geodynamic outlook and multi- layer-sliding tectonic outlook, is one of new keys to study 3-dimensional solid and its 4-dimensional evolution history of global tectonic system controlled by global geodynamics system. The LBT concept is applied to study the lithospheric tectonics of the southern South China Sea (SCS). Based on the analysis of about 30 000 km of geophysical and geological data, some layer-blocks in the Nansha micro-plate can be divided as Nansha ultra-crustal layer-block, Zengmu crustal layer-block, Nanwei (Rifleman bank)-Andu (Ardasier bank) and Liyue (Reed bank)-North Palawan crustal layer-blocks, Andu-Bisheng and Liyue-Banyue basemental layer-blocks. The basic characteristics of the basemental layer-blocks have been dicussed, and three intra-plate basin groups are identified. The intra-plate basins within Nansha micro-plate can be divided into three basin groups of NanweiAndu, Feixin-Nanhua, and Liyue-North Palawan based on the different geodynamics. In the light of pluralistic geodynamic concept, the upheaving force induced by the mid-crust plastic layer is proposed as the main dynamical force which causes the formation of the intra-plate basins within the Nansha micro-plate. Finally, models of a face-to-face dip-slip-detachment of basemental layer- block and a unilateral dip-slip-detachment of basemental layer-block are put forward for the forming mechanisms of the Nanwei-Andu and Liyue-North Palawan intra-plate basin groups, respectively. | LIU Hailing XIE Guofa LIN Qiujin ZHENG Hongbo LIU Yingchun | 2009 | Acta Oceanologica Sinica2009,28,3: | 3 |
| 16 | Mesozoic Deformation and Its Geological Significance in the Southern Margin of the South China Sea显示文摘The pre-Eocene history of the region around the present South China Sea is not well known. New multi-channel seismic profiles provide valuable insights into the probable Mesozoic history of this region. Detailed structural and stratigraphic interpretations of the multi-channel seismic profiles, calibrated with relevant drilling and dredging data, show major Mesozoic structural features. A structural restoration was done to remove the Cenozoic tectonic influence and calculate the Mesozoic tectonic compression ratios. The results indicate that two groups of compressive stress with diametrically opposite orientations, S(S)E– N(N)W and N(N)W–S(S)E, were active during the Mesozoic. The compression ratio values gradually decrease from north to south and from west to east in each stress orientation. The phenomena may be related to the opening of the proto-South China Sea(then located in south of the Nansha block) and the rate at which the Nansha block drifted northward in the late Jurassic to late Cretaceous. The Nansha block drifted northward until it collided and sutured with the southern China margin. The opening of the present South China Sea may be related to this suture zone, which was a tectonic zone of weakness. | ZHU Rongwei LIU Hailing YAO Yongjian WANG Yin | 2018 | Journal of Ocean University of China2018,17,4: | 3 |
| 17 | Highly active Pd containing EMT zeolite catalyst for indirect oxidative carbonylation of methanol to dimethyl carbonate显示文摘Palladium containing EMT zeolite catalyst(Pd/EMT) was prepared and used for the indirect oxidative carbonylation of methanol to dimethyl carbonate(DMC).The EMT zeolite was employed as a new catalyst support and compared with the conventional Pd containing FAU zeolite catalyst(Pd/FAU).The Pd/EMT in contrast to the Pd/FAU catalyst exhibited high intrinsic activity with the turnover frequency of 0.25 s^(-1) vs.0.11 s^(-1).The Pd/EMT catalyst showed high CO conversion of 82% and DMC selectivity of 79%,that maintained for at least 130 h,while the activity of the Pd/FAU catalyst rapidly deteriorated within 12 h.The enhanced interactions between Pd and EMT zeolite inhibited the sintering of palladium clusters and maintained the Pd2+ active sites in the Pd/EMT catalyst.The stabilization of the mono-dispersed Pd clusters within the EMT zeolite is paramount to the excellent performance of the catalyst for the indirect oxidative carbonylation of methanol to DMC. | Chunzheng Wang Weisong Xu Zhengxing Qin Hailing Guo Xinmei Liu Svetlana Mintova | 2021 | Journal of Energy Chemistry2021,30,1: | 3 |

| 19 | Enhanced catalysis of ultrasmall Au-MoS_2 clusters against reactive oxygen species for radiation protection显示文摘Ionizing radiation produces excessive reactive oxygen species(ROS) which impose detrimental effects on biological systems. Thus, it is important to explore clinically safe and efficacious radioprotection agents to scavenge ROS and reduce the risks of radiotherapy. Recently, emerging catalytic nanomaterials such as sulfide nanomaterials have shown capability of clearing ROS in vivo by unique electron transfers between atoms, but their catalytic activities are yet suboptimal. As such, there is an unmet need to improve catalytic properties for stronger antioxidant activities and radiation protection. Herein, we prepared ultrasmall Au-MoS_2 clusters(~2.5 nm) and they showed enhanced catalytic properties via gold intercalation facilitating increased active sites and synergistic effects. Electrocatalysis results revealed that the catalytic activity of Au-MoS_2 towards H2O_2 was superior to ultrasmall MoS_2 without Au. As a result, we found that improving the electrocatalytic property of Au-MoS_2 can effectively enhance corresponding antioxidant activities and radioprotection effects in vivo. In addition, Au-MoS_2 also showed significant radioprotection in vitro and dramatically reduced the excess of radiation-induced adverse ROS. It also rescued radiation-induced DNA damages and protected the bone marrow hematopoietic system from ionizing radiation. | Peixian Bian Jinxuan Zhang Junying Wang Jiang Yang Jingya Wang Haile Liu Yuanming Sun Meixian Li Xiao-Dong Zhang | 2018 | Science Bulletin2018,63,14: | 2 |
| 20 | Symbolic algorithmic verification of intransitive generalized noninterference显示文摘Generalized noninterference can be used to formulate transitive security policies,but is unsuitable for intransitive security policies.We propose a new information flow security property,which we call intransitive generalized noninterference,that enables intransitive security policies to be specified formally.Next,we propose an algorithmic verification technique to check intransitive generalized noninterference.Our technique is based on the search for counterexamples and on the window induction proof,and can be used to verify generalized noninterference.We further demonstrate that the search of counterexamples and induction proof can be reduced to quantified Boolean satisfiability.This reduction enables us to use efficient quantified Boolean decision procedures to perform the check of intransitive generalized noninterference.It also reduces spatial requirement by representing the space compactly,and improves the efficiency of the verification procedure. | ZHOU CongHua LIU ZhiFeng WU HaiLing CHEN Song JU ShiGuang | 2012 | Science China(Information Sciences)2012,55,7: | 2 |
