| 1 | Quantitative characterization of reservoir space in the Lower Silurian Longmaxi Shale,southern Sichuan,China显示文摘Based on the drilling data of the Upper Ordovician Wufeng Shale and the Lower Silurian Longmaxi Shale in southern Sichuan Basin,the construction of matrix pores and the development condition of fractures in a marine organic-rich shale are quantitatively evaluated through the establishment of the reservoir petrophysical models and porosity mathematical models.Our studies show that there are four major characteristics of the Longmaxi Shale confirmed by the quantitative characterization:(1)the pore volume of per unit mass is the highest in organic matter,followed in clay minerals,finally in brittle minerals;(2)the porosity of the effective shale reservoir is moderate and equal to that of the Barnett Shale,and the main parts of the shale reservoir spaces are interlayer pores of clay minerals and organic pores;(3)the porosity of the organic-rich shale is closely related to TOC and brittle mineral/clay mineral ratio,and mainly increases with TOC and clay mineral content;(4)fractures are developed in this black shale,and are mainly micro ones and medium-large ones.In the Longmaxi Shale,the fracture density increases from top to bottom,reflecting the characteristics with high brittle mineral content,high Young’s modulus,low Poisson's ratio and high brittleness at its bottom. | WANG YuMan DONG DaZhong YANG Hua HE Ling WANG ShiQian HUANG JinLiang PU BoLing WANG ShuFang | 2014 | Science China Earth Sciences2014，57，2： | 36 |
| 2 | Kaili Biota: A Taphonomic Window on Diversification of Metazoans from the Basal Middle Cambrian: Guizhou, China显示文摘A Burgess Shale-type biota is, in part, characterized by a wide diversity of taxa and soft-part preservation. Each provides unique historical insights into early metazoan evolution. Among the more than 40 globally distributed biotas, the early Cambrian Chengjiang and Middle Cambrian Burgess-type biotas are the largest. The Kaili Biota, from the earliest Middle Cambrian of Guizhou, China, contains representatives of 110 metazoan genera belonging to 10 phyla. It contains many well-persevered soft-bodied specimens. This Chinese biota has become the third most taxonomically diverse Burgess Shale-type fauna. Because the Kaili Biota formed in an outer-shelf environment, its main faunal character is large numbers of eocrinoids and planktoic trilobites. The Kaili is younger than the Chengjiang Biota but older than the Canadian Burgess Shale Biota; it shares 30 genera with the Chengjiang and 38 genera with the Burgess Biota. The Kaili Biota displays a taphonomic window to the diversification and evolution of marine offshore organisms covering 5.13 million years between the Early and Middle Cambrian. | ZHAO Yuanlong ZHU Maoyan Loren E.

| 3 | Progress in China's Unconventional Oil & Gas Exploration and Development and Theoretical Technologies显示文摘The new century has witnessed a strategic breakthrough in unconventional oil & gas.Hydrocarbon accumulated in micro-/nano-scale pore throat shale systems has become an important domain that could replace current oil & gas resources.Unconventional oil & gas plays an increasingly important role in our energy demand.Tight gas,CBM,heavy oil and asphaltic sand have served as a key domain of exploration & development,with tight oil becoming a 'bright spot' domain and shale gas becoming a 'hotspot' domain.China has made great breakthroughs in unconventional oil & gas resources,such as tight gas,shale gas,tight oil and CBM,and great progress in oil shale,gas hydrate,heavy oil and oil sand.China has an estimated(223-263)×10~8t of unconventional oil resources and(890-1260)×l0^(12)m^3 of gas resources.China has made a breakthrough for progress in unconventional oil & gas study.New progress achieved in fine-grained sedimentary studies related to continental open lacustrine basin large-scale shallow-water delta sand bodies,lacustrine basin central sandy clastic flow sediments and marine-continental fine-grained sediments provide a theoretical basis for the formation and distribution of basin central reservoir bodies.Great breakthroughs have been made in unconventional reservoir geology in respect of research methodology & technology,multi-scale data merging and physical simulation of formation conditions.Overall characterization of unconventional reservoirs via multi-method and multi-scale becomes increasingly popular and facilitates the rapid development of unconventional oil & gas geological theory,method and technology.The formation of innovative,continuous hydrocarbon accumulation theory,the establishment of the framework of the unconventional oil & gas geological theory system,and the determination of the implications,geological feature,formation mechanism,distribution rule and core technology of unconventional oil& gas geological study lays a theoretical foundation for extensive unconventional oil & gas exploration and development.Theories and technologies of unconventional oil & gas exploration and development developed rapidly,including some key evaluation techniques such as 'sweet spot zone' integrated evaluation and a six-property evaluation technique that uses hydrocarbon source,lithology,physical property,brittleness,hydrocarbon potential and stress anisotropy,and some key development &engineering technologies including micro-seismic monitoring,horizontal drilling & completion and 'factory-like' operation pattern, 'man-made reservoir' development,which have facilitated the innovative development of unconventional oil & gas.These breakthroughs define a new understanding in four aspects:①theoretical innovation;② key technologies;③ complete market mechanism and national policy support;and ④ well-developed ground infrastructure,which are significant for prolonging the life cycle of petroleum industry,accelerating the upgrade and development of theories and technologies and altering the global traditional energy structure. | ZOU Caineng YANG Zhi ZHU Rukai ZHANG Guosheng HOU Lianhua WU Songtao TAO Shizhen YUAN Xuanjun DONG Dazhong WANG Yuman WANG Lan HUANG Jinliang WANG Shufang | 2015 | Acta Geologica Sinica(English Edition)2015，89，3： | 27 |
| 4 | Progress and significance in research on the early Middle Cambrian Kaili Biota, Guizhou Province, China显示文摘Important progress in research on the Kaili Biota has been made recently. Many interesting components from Chengjiang Biota and Burgess Shale Biota have been discovered, e.g. Microdictyon of lobopodia; Ottoia, Palaeoscolex of worms; Naraoia, Marrella of Trilobitioidea, Mollisonia, anamalocarids and other non-trilobite arthropods; and new sorts of echinoder-mas, macroalage fossils and so on. Recent work on the Kaili Biota has resulted in the following developments: (i) an increase in the number of animal genera, up to more than 100 genera in total, so that the Kaili Biota has become the third most diverse of the Burgess Shale-type Biota after the Burgess Shale and Chengjiang Biotas; and (ii) the most noteworthy fossils in the Kaili Biota are echinoderms, non-trilobite arthropods and soft-bodied medusiform fossils, especially the most diverse echinoderms. The progress provides envidence for the biodiversity of marine organisms presented after the 'Cambrian Explosion' and serves as a link between the earlist Cambrian Chengjiang Biota and late early Middle Cambrian Burgess Shale Biota. It is of great significance in the reconstruction of the Cambrian palaeoplate, palaeongeography and in research on taphonomy. | ZHAO Yuanlong, YUAN Jinliang, ZHU Maoyan, YANG Ruidong, GUO Qingjun, PENG Jin and YANG Xinglian(1.

| 6 | Improvement of oxytetracycline production mediated via cooperation of resistance genes in Streptomyces rimosus显示文摘Increasing the self-resistance levels of Streptomyces is an effective strategy to improve the production of antibiotics.To increase the oxytetracycline(OTC) production in Streptomyces rimosus,we investigated the cooperative effect of three co-overexpressing OTC resistance genes:one gene encodes a ribosomal protection protein(otrA) and the other two express efflux proteins(otrB and otrC).Results indicated that combinational overexpression of otrA,otrB,and otrC(MKABC) exerted a synergetic effect.OTC production increased by 179%in the recombinant strain compared with that of the wild-type strain M4018.The resistance level to OTC was increased by approximately two-fold relative to the parental strain,thereby indicating that applying the cooperative effect of self-resistance genes is useful to improve OTC production.Furthermore,the previously identified cluster-situated activator OtcR was overexpressed in MKABC in constructing the recombinant strain MKRABC;such strain can produce OTC of approximately7.49 g L^((-1)),which represents an increase of 19%in comparison with that of the OtcR-overexpressing strain alone.Our work showed that the cooperative overexpression of self-resistance genes is a promising strategy to enhance the antibiotics production in Streptomyces. | Shouliang Yin Xuefeng Wang Mingxin Shi Fang Yuan Huizhuan Wang Xiaole Jia Fang Yuan Jinliang Sun Tiejun Liu Keqian Yang Yuxiu Zhang Keqiang Fan Zilong Li | 2017 | Science China(Life Sciences)2017，60，9： | 10 |
| 7 | Methods for Shale Gas Play Assessment: A Comparison between Silurian Longmaxi Shale and Mississippian Barnett Shale显示文摘Based on field work, organic geochemical analyses and experimental testing, a six-property assessment method for shale gas is proposed. These six properties include organic matter properies, lithofacies, petrophysical properties, gas content, brittleness and local stress field. Due to the features of continuous distribution over a large area and low resource abundance in shale plays, a sweet spot should have these following properties:(a) TOC>2%;(b) brittle minerals content(>40%) and clay minerals(<30%);(c) Ro(>1.1%);(d) porosity(>2%) and permeability(>0.000 1 m D), and(e) effective thickness(30–50 m). Applying these criteria in the Sichuan Basin, the Silurian Longmaxi shale consists of four prospecting sweet spots, including blocks of Changning, Weiyuan, Zhaotong and Fushun-Yongchuan. Although these four blocks have some similarities, different features were usually observed. After comprehensive analyses using the six-property assessment method, the Fushun-Yongan Block ranks the most favorable sweet spot, followed by the Weiyuan Block. For the other two blocks, the Changning Block is better than the Zhaotong Block. By comparing with the Mississippian Barnett shale, characteristics that are crucial for a high-yielding in the Sichuan Basin include a high content of organic matter(TOC>2.5%), a moderate thermal maturity(Ro=0.4%–2%), a high content of brittle minerals(quartz: 30%–45%), a high gas content(>2.5 m3?t-1), and types I and II1 kerogen. | Songqi Pan Caineng Zou Zhi Yang Dazhong Dong Yuman Wang Shufang Wang Songtao Wu Jinliang Huang Qun Liu Dule Wang Ziyuan Wang | 2015 | Journal of Earth Science2015，26，2： | 10 |
| 8 | Shale Gas Formation and Occurrence in China: An Overview of the Current Status and Future Potential显示文摘Shale gas is one of the most promising unconventional resources both in China and abroad. It is known as a form of self-contained source-reservoir system with large and continuous dimensions. Through years of considerable exploration efforts, China has identified three large shale gas fields in the Fuling, Changning and Weiyuan areas of the Sichuan Basin, and has announced more than 540 billion m^3 of proven shale gas reserves in marine shale systems. The geological theories for shale gas development have progressed rapidly in China as well. For example, the new depositional patterns have been introduced for deciphering the paleogeography and sedimentary systems of the Wufeng shale and Longmaxi shale in the Sichuan Basin. The shale gas storage mechanism has been widely accepted as differing from conventional natural gas in that it is adsorbed on organic matter or a mineral surface or occurs as free gas trapped in pores and fractures of the shale. Significant advances in the techniques of microstructural characterization have provided new insights on how gas molecules are stored in micro- and nano-scale porous shales. Furthermore, newly-developed concepts and practices in the petroleum industry, such as hydraulic fracturing, microseismic monitoring and multiwell horizontal drilling, have made the production of this unevenly distributed but promising unconventional natural gas a reality. China has 10–36 trillion m^3 of promising shale gas among the world's whole predicted technically recoverable reserves of 206.6 trillion m^3. China is on the way to achieving its goal of an annual yield of 30–50 billion m^3 by launching more trials within shale gas projects. | ZOU Caineng YANG Zhi PAN Songqi CHEN Yanyan LIN Senhu HUANG Jinliang WU Songtao DONG Dazhong WANG Shufang LIANG Feng SUN Shasha HUANG Yong WENG Dingwei | 2016 | Acta Geologica Sinica(English Edition)2016，90，4： | 9 |
| 9 | Development and dynamic characteristics of an Organic Rankine Cycle显示文摘The design, construction and test of an Organic Rankine Cycle(ORC) with R123 as the working fluid were performed. A scroll expander was integrated in the system.The conductive oil with its temperature of 150 °C was used to simulate the low-grade heat source. An AC dynamometer unit measured the expander shaft torque, rotating speed and shaft power. The experiments were conducted in two operating modes: the constant mass flow rate and the constant shaft torque. Under the constant mass flow rate operating mode, the stepped increase of the shaft torque increased the expansion ratios of the expander and decreased the vapor superheats at the expander inlet. Thus,the shaft power and thermal efficiency were increased.Alternatively, the constant shaft torque operating mode involved two different regions, interfaced at the pumping frequency of 9 Hz. By the increase of the mass flow rates,the vapor superheats at the expander inlet was decreased and the shaft power was increased, but the ORC thermal efficiencies were slightly decreased. Both operating modes yielded the saturation shaft powers that were the maximum values one could use. It was found that the measured shaft powers and ORC thermal efficiencies were lower than the enthalpy determined values based on the fluid pressures and temperatures at the expander inlet and outlet. The maximum measured shaft power and thermal efficiency were 2.63 kW and 5.31 %, compared with the enthalpy determined values of 3.87 kW and 9.46 %, respectively. | Zheng Miao Xufei Yang Jinliang Xu Jinghuang Zou | 2014 | Chinese Science Bulletin2014，59，33： | 9 |

| 11 | Cambrian integrative stratigraphy and timescale of China显示文摘The Cambrian Period is the first period of the Phanerozoic Eon and witnessed the explosive appearance of the metazoans, representing the beginning of the modern earth-life system characterized by animals in contrary to the Precambrian earth-life system dominated by microbial life. However, understanding Cambrian earth-life system evolution is hampered by regional and global stratigraphic correlations due to an incomplete chronostratigraphy and consequent absence of a highresolution timescale. Here we briefly review the historical narrative of the present international chronostratigraphic framework of the Cambrian System and summarize recent advances and problems of the undefined Cambrian stage GSSPs, in particular we challenge the global correlation of the GSSP for the Cambrian base, in addition to Cambrian chemostratigraphy and geochronology. Based on the recent advances of the international Cambrian chronostratigraphy, revisions to the Cambrian chronostratigraphy of China, which are largely based on the stratigraphic record of South China, are suggested, and the Xiaotanian Stage is newly proposed for the Cambrian Stage 2 of China. We further summarize the integrative stratigraphy of South China, North China and Tarim platforms respectively with an emphasis on the facies variations of the Precambrian-Cambrian boundary successions and problems for identification of the Cambrian base in the different facies and areas of China. Moreover, we discuss stratigraphic complications that are introduced by poorly fossiliferous dolomite successions in the upper Cambrian System which are widespread in South China, North China and Tarim platforms. | Maoyan ZHU Aihua YANG Jinliang YUAN Guoxiang LI Junming ZHANG Fangchen ZHAO Soo-Yeun AHN Lanyun MIAO | 2019 | Science China Earth Sciences2019，62，1： | 8 |
| 12 | Enhanced Photocatalytic Degradation of Rhodamine B by Cu_2O Coated Silicon Nanowire Arrays in Presence of H_2O_2显示文摘Highly ordered Cu2 O coated silicon nanowire arrays(Si NWAs) were fabricated as photocatalyst via depositing Cu nanoparticles on silver-assisted electroless-etched Si NWAs and subsequently annealing. The as-prepared samples have been characterized by scanning electron microscopy, X-ray diffraction and UV e VIS e NIR spectrophotometry. The photocatalytic properties of the Cu2 O coated Si NWAs were investigated by degradation of Rhodamine B(Rh B) under simulated solar light with a cut-off filter(l > 420 nm). The results indicated that H2O2 could greatly improve the photocatalytic properties of Cu2 O coated Si NWAs, and exhibited strong synergy effect between them. The hybrid nanowire arrays will be promising photocatalytic materials in the field of energy and environment. | Chengtao Yang Jinliang Wang Lirun Mei Xiaoyu Wang | 2014 | Journal of Materials Science & Technology2014，30，11： | 7 |
| 13 | Recent Progress on Data-Based Optimization for MineralProcessing Plants显示文摘In the globalized market environment, increasingly significant economic and environmental factors withincomplex industrial plants impose importance on the optimization of global production indices; such opti-mization includes improvements in production efficiency, product quality, and yield, along with reductionsof energy and resource usage. This paper briefly overviews recent progress in data-driven hybrid intelli-gence optimization methods and technologies in improving the performance of global production indicesin mineral processing. First, we provide the problem description. Next, we summarize recent progress indata-based optimization for mineral processing plants. This optimization consists of four layers: optimiza-tion of the target values for monthly global production indices, optimization of the target values for dailyglobal production indices, optimization of the target values for operational indices, and automation systemsfor unit processes. We briefly overview recent progress in each of the different layers. Finally, we point outopportunities for future works in data-based optimization for mineral processing plants. | Jinliang Ding Cuie Yang Tianyou Chai | 2017 | Engineering2017，3，2： | 7 |
| 14 | Provenance for the Chang 6 and Chang 8 Member of the Yanchang Formation in the Xifeng area and in the periphery Ordos Basin: Evidence from petrologic geochemistry显示文摘Study indicates that the major paleocurrent and source direction for the Chang 8 Member of the Yangchang Formation, Upper Triassic in the Xifeng area of the southwestern Ordos Basin derived from the southwest direction with the southeast source as the subordinate one. While the Chang 6 Member was influenced not only by the same source as that of the Chang 8 Member from the southwest and the southeast direction, but also affected by the northeast and the east provenance around the Ordos Basin, based upon measurement of paleocurrents on outcrops located in the periphery Ordos Basin, analysis of framework grains and heavy minerals in sandstones of the Chang 6 and Chang 8 Members and their spatial distribution in the study area, combined with characteristics of trace elements and rare-earth elements of mudstones and of a small amount of sandstones in the Xifeng area and outcrops in margin of the Ordos Basin. The Yuole-Xuanma-Gucheng-Heshui-Ningxia region located in the northeastern and the eastern Xifeng area was the mixed source area where the southwest, southeast, northeast and the east sources were convergent till the Chang 6 Member was deposited. The rare earth elements of the Chang 6 and Chang 8 Members are characterized by slight light rare earth-elements (LREE) enrichment and are slightly depleted in heavy rare earth-elements (HREE) with weak to moderate negative abnormal Eu, resulting in a right inclined REE pattern, which implies that the source rocks are closely related with better differential crust material. Analysis on geochemical characteristics of the mudstones and sandstones, features of parent rocks in provenance terranes and tectonic settings shows that source rocks for the Chang 8 Member mainly came from metamorphic and sedimentary rocks in transitional continental and basement uplift terranes with a small amount of rocks including metamorphic, sedimentary and igneous rocks coming from mixed recycle orogenic belt located in the southwest margin of the Ordos basin. Rocks in the crystalline basement and the overlying sedimentary cover in a basement uplift setting in the northeast periphery of the basin also contributed a part of the sources for the Chang 6 Member, in addition to the sources deriving from transitional continental and basement uplift terranes in the southwest margin of the basin. Parent rocks of the provenance terrane in the northeast margin of the Ordos Basin are characterized by having more felsic rocks. | LUO JingLan LI Jian YANG BingHu DAI YaQuan LI Bo HAN YongLin WANG HaiHong DU JinLiang | 2007 | Science China Earth Sciences2007，50，z2： | 6 |
| 15 | Vertically oriented TiO_2 nanotube arrays with different anodization times for enhanced boiling heat transfer显示文摘Pool boiling of saturated water on a plain Ti surface and surfaces covered with vertically-oriented TiO2 nanotube arrays(NTAs) has been studied.The technique of potentiostatic anodization using non-aqueous electrolytes was adopted to fabricate three types of TiO2 NTAs distinguished by their anodization time.Compared to the bare Ti surface,the incipient boiling wall superheat on the TiO2 NTAs was decreased by 11 K.Both the critical heat flux and heat transfer coefficient of pool boiling on the TiO2 NTAs were higher than those from boiling on a bare Ti surface.The measured maximum critical heat flux and heat transfer coefficient values were 186.7 W/cm2 and 6.22 W/cm2K,respectively.Different performances for the enhancement of heat transfer by the three types of TiO2 NTAs were attributed to the different degrees of deformation in the nanostructure during boiling.Long-term performance of the nanomaterial-coated surfaces for enhanced pool boiling showed degradation of the TiO2 NTAs prepared with an anodization time of 3 hours. | XU Jia YANG MingJie XU JinLiang JI XianBing | 2012 | Science China(Technological Sciences)2012，55，8： | 6 |
| 16 | Recent advances of phase engineering in group VI transition metal dichalcogenides显示文摘As the crystal quality and phase structure of two-dimensional(2D)transition metal dichalcogenides(TMDs)have significant impacts on their properties such as electroconductivity,superconductivity and chemical stability,the precise synthesis,which plays an important role in fundamental researches and industrial applications,is highly required.Group VI TMDs,such as MoS_(2),usually exhibit diverse polymorphs including semiconducting 1H and metallic 1T phases.Even great efforts are devoted to revealing the structure-dependent physicochemical nature of TMDs by modulating their phases from the stable to the metastable at the atomic scale,there are still challenges on the phase-controlled synthesis of Group VI TMDs with metallic or semimetal properties.In this review,methods such as ion intercalation,chemical doping,strain engineering,defect triggering,and electric-field treatment are examined in detail.Finally,challenges and opportunities in this research field are proposed. | Lingjia Meng Yang Ma Kunpeng Si Shiyu Xu Jinliang Wang Yongji Gong | 2019 | Tungsten2019，1，1： | 6 |
| 17 | Bathynotus:A key trilobite taxon for global stratigraphic boundary correlation between Cambrian Series 2 and Cambrian Series 3显示文摘The Cambrian trilobite Bathynotus is a special morphology of Redlichiid,which is characterized by a wider thorax axis and an 11th macropleural segment bearing a long,backwardly directed spine.Additionally,its 12th and 13th pleural segments are narrow and they terminate at a fulcrum where they fuse together and to the posterior edge of the long macropleural spine.The genus is widely distributed,occurring in North America,Siberia,the Altay-Sayan fold belt of Russia,South China,the Tarim Basin of China,and Australia.It occurs primarily in deposits of the upper part of the continental slope,at the transition between stable platform settings and subsiding margins of the late Early Cambrian.Here,we recognize three species of Bathynotus from China,including B.holopygus which is widespread around the world.Although six species of Bathynotus have been reported from Siberia and the Altay-Sayan fold belt area of Russia,data presented here suggest that only three of these species are valid.Bathynotus exhibits a short geological range,with its first occurrence late in the unnamed Cambrian Series 2 and the last appearance datum of Bathynotus at the boundary of Cambrian Series 2 and Cambrian Series 3.The late appearance datum(LAD) of Bathynotus provides an important global stratigraphic marker of the boundary between Cambrian Series 2 and Cambrian Series 3. | Jin Peng Yuanlong Zhao Jinliang Yuan Lu Yao Hong Yang | 2009 | Progress in Natural Science:Materials International2009，19，1： | 5 |
| 18 | Edgence: A Blockchain-Enabled Edge-Computing Platform for Intelligent IoT-Based dApps显示文摘Nowadays scalable Io T management is a bottleneck of Io T development due to the geographically dispersed distribution, fragmented ownerships, and ever-growing population of Io T devices. To intelligently manage massive decentralized applications(d Apps) in Io T usecases, Edgence(EDGe + intellig ENCE) is proposed to use edge clouds to access Io T devices and users, and then use its in-built blockchain to realize self-governing and self-supervision of the edge clouds. Edgence proposes to use masternode technology to introduce Io T devices and users into a closed blockchain system, which can extend the range of blockchain to Io T-based d Apps. Further, masternodes do good to scalability by raising the TPS(transactions per second) of the blockchain network. To support various d Apps, a three-tier validation is proposed, namely script validation, smartcontract validation, and masternode validation. To avoid energy consumption resulted by blockchain consensus, Edgence proposes a random but verifiable way to elect a masternode to generate each new block. The potential of the tailored Edgence is shown by examples of decentralized crowdsourcing and AI training. | Jinliang Xu Shangguang Wang Ao Zhou Fangchun Yang | 2020 | China Communications2020，17，4： | 5 |
| 19 | A new strain of Crimean-Congo hemorrhagic fever virus isolated from Xinjiang, China显示文摘Crimean-Congo hemorrhagic fever virus(CCHFV) is a highly pathogenic tick-borne virus with a fatality rate of up to 50% in humans. CCHFV is widely distributed in countries around the world.Outbreaks of CCHFV infection in humans have occurred in prior years in Xinjiang Province, China.Epidemiological surveys have detected CCHFV RNA in ticks and animals; however, few isolates were identified. In this study, we identified and isolated a new CCHFV strain from Hyalomma asiaticum asiaticum ticks collected from north of Tarim Basin in Xinjiang, China. A preliminary investigation of infection and antigens expression of CCHFV was performed in newborn mice. The target tissues for CCHFV replication in newborn mice were identified. The analysis of the phylogenetic relationships with other Chinese strains suggested that diverse genotypes of CCHFV have circulated in Xinjiang for years. These findings provide important insights into our understanding of CCHFV infection and evolution as well as disease prevention and control for local residents. | Rong Guo Shu Shen Yanfang Zhang Junming Shi Zhengyuan Su Dan Liu Jinliang Liu Juan Yang Qiguo Wang Zhihong Hu Yujiang Zhang Fei Deng | 2017 | Virologica Sinica2017，32，1： | 5 |
| 20 | Increased mitochondrial fission drives the reprogramming of fatty acid metabolism in hepatocellular carcinoma cells through suppression of Sirtuin 1显示文摘Background:Mitochondria are dynamic organelles that constantly change their morphology through fission and fusion processes.Recently,abnormally increased mitochondrial fission has been observed in several types of can-cer.However,the functional roles of increased mitochondrial fission in lipid metabolism reprogramming in cancer cells remain unclear.This study aimed to explore the role of increased mitochondrial fission in lipid metabolism in hepa-tocellular carcinoma(HCC)cells.Methods:Lipid metabolism was determined by evaluating the changes in the expressions of core lipid metabolic enzymes and intracellular lipid content.The rate of fatty acid oxidation was evaluated by[PH]-labelled oleic acid.The mito-chondrial morphology in HCC cells was evaluated by fluorescent staining.The expression of protein was determined by real-time PCR,imnmunohistochemistry and Western blotting.Results:Activation of mitochondrial fission significantly promoted de novo fatty acid synthesis in HCC cells through upregulating the expression of lipogenic genes fatty acid synthase(FASN),acetyl-CoA carboxylasel(ACCI),and elonga-tion of very long chain fatty acid protein 6(ELOVL6),while suppressed fatty acid oxidation by downregulating carnitine palmitoyl transferase 1A(CPTIA)and acyl-CoA oxidase 1(ACOX1).Consistently,suppressed mitochondrial fission exhibited the opposite effects.Moreover,in vitro and in vivo studies revealed that mitochondrial fission-induced lipid metabolism reprogramming significantly promoted the proliferation and metastasis of HCC cells.Mechanistically,mito-chondrial fission increased the acetylation level of sterol regulatory element-binding protein 1(SREBPI)and peroxisome proliferator-activated receptor coaC-tivator 1 alpha(PGC-1a)by suppressing nicotinamide adenine dinucleotide(NAD+)/Sirtuin 1(SIRTI)signaling.The elevated SREBP1 then upregulated the expression of FASN,ACC1 and ELOVL6 in HCC cells,while PGC-1c/PPARa sup-pressed the expression of CPTIA and ACOXL Conclusions:Increased mitochondrial fission plays a crucial role in the repro-gramming of lipid metabolism in HCC cells,which provides strong evidence for the use of this process as a drug target in the treatment of this malignancy. | Dan Wu Yi Yang Yiran Hou Zifeng Zhao Ning Liang Peng Yuan Tao Yang Jinliang Xing Jibin Li | 2022 | Cancer Communications2022，42，1： | 4 |
