| 1 | 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 |

| 3 | Localization and characterization of the hypothetical protein CT440 in Chlamydia trachomatis-infected cells显示文摘The inclusion membrane proteins play potentially important roles in chlamydial biology and pathogenesis.Here we localized and characterized the hypothetical protein CT440 in Chlamydia trachomatis-infected cells.The open reading frame(ORF) encoding the CT440 protein from the C.trachomatis serovar D genome was cloned into the prokaryotic expression vector pGEX-6p and expressed as a glutathione-S-transferase(GST) fusion protein in E.coli XL1-Blue.The CT440 fusion protein was used to immunize mice to raise antigen-specific antibody.After verification by Western blot and immunofluorescence assay(IFA),the specific antibody was used to localize the endogenous CT440 protein and to detect its expression pattern in Chlamydia-infected cells.Cytosolic expression of CT440 in HeLa cells was also carried out to evaluate the effect of the CT440 protein on the subsequent chlamydial infection.The results showed that the hypothetical protein CT440 was localized in the C.trachomatis inclusion membrane,and was detectable 12 h after chlamydial infection.Expression of CT440 in the cytoplasm did not inhibit the subsequent chlamydial infection.In summary,we have identified a new inclusion membrane protein that may be an important candidate for understanding C.trachomatis pathogenesis. | LI ZhongYu HUANG QiuLin SU ShengMei ZHOU Zhou CHEN ChaoQun ZHONG GuangMing WU YiMou | 2011 | Science China(Life Sciences)2011，54，11： | 5 |
| 4 | New advances in the assessment of tight oil resource in China显示文摘The research on tight oil becomes another hotspot in the field of unconventional oil and gas after the boom of shale gas.The global recoverable resources of tight oil are estimated to be around 47.3×10^(9)t.In recent years,significant progress has been made in the technologies of tight oil exploration and development in North America,thus stimulating the dramatic increase of tight oil production.Meanwhile,China has also acquired remarkable achievements in tight oil exploration.Mature assessment methods have been established for tight oil resources by the US,generally dominated by analogy and statistical methods with their own advantages and disadvantages as well as applicable conditions.In China,improvement of resource evaluation techniques becomes an urgent issue in increasing tight oil reserve and production.This study mainly discusses the resource evaluation methods and resource enrichment characteristics of tight oil.Seven kinds of assessment methods in three categories(i.e.,analogy,statistical and genetic method)and evaluation parameters have been preliminary established,and are specifically applied in the Sichuan,Ordos,Songliao,Junggar,Bohai Bay and other tight oil basins through the newly hierarchical resource abundance analogy method,the estimated ultimate recovery(EUR)analogy method and the small-cell volumetric method.The preliminary evaluation results reveal that China has great potential in tight oil resource,and the geological resources amount to 20×10^(9)t,providing a resource base for large-scale development. | Shejiao Wang Yuanjiang Yu Qiulin Guo Shaoyong Wang Xiaozhi Wu | 2017 | Petroleum Research2017，2，1： | 4 |
| 5 | RESEARCH AND APPLICATION OF CROP PEST MONITORING AND EARLY WARNING TECHNOLOGY IN CHINA显示文摘The importance of food security,especially in combating the problem of acute hunger,has been underscored as a key component of sustainable development.Considering the major challenge of rapidly increasing demands for both food security and safety,the management and control of major pests is urged to secure supplies of major agricultural products.However,owing to global climate change,biological invasion(e.g.,fall armyworm),decreasing agricultural biodiversity,and other factors,a wide range of crop pest outbreaks are becoming more frequent and serious,making China,one of the world’s largest country in terms of agricultural production,one of the primary victims of crop yield loss and the largest pesticide consumer in the world.Nevertheless,the use of science and technology in monitoring and early warning of major crop pests provides better pest management and acts as a fundamental part of an integrated plant protection strategy to achieve the goal of sustainable development of agriculture.This review summarizes the most fundamental information on pest monitoring and early warning in China by documenting the developmental history of research and application,Chinese laws and regulations related to plant protection,and the National Monitoring and Early Warning System,with the purpose of presenting the Chinese model as an example of how to promote regional management of crop pests,especially of cross border pests such as fall armyworm and locust,by international cooperation across pest-related countries. | Qiulin WU Juan ZENG Kongming WU | 2022 | Frontiers of Agricultural Science and Engineering2022，9，1： | 2 |
| 6 | Characteristics of Volcanic Reservoirs and Hydrocarbon Accumulation of Carboniferous System in Junggar Basin, China显示文摘The Carboniferous volcanic reservoirs in Junggar Basin contain rich hydrocarbon resources,implying a great exploration potential,so that they have become a key replacement target for“three-dimensional exploration”.The study on the Carboniferous volcanic reservoirs and their hydrocarbon accumulation elements is significant for clarifying the orientation for exploration.In this paper,based on 37 reserves reports and 3200 reservoir test data,the Carboniferous volcanic reservoirs in Junggar Basin were discussed from the prospective of lithology and lithofacies,physical properties,reservoir types,main controls on hydrocarbon accumulation,and hydrocarbon accumulation patterns.It is found that the Carboniferous in the basin is mostly in the multi-island ocean-volcanic island arc structural-sedimentary environment,so it is geologically eligible for forming in-situ volcanic reservoirs.The volcanic rocks are:(1)mostly distributed along deep and large faults,with the lithology and lithofacies controlled by volcanic architectures;(2)dominantly lava,followed by volcaniclastic lava and volcaniclastic rock;(3)distributed in the periphery of hydrocarbon-generating sag and within the source rocks horizontally,and concentrated in the weathering crust at the top longitudinally,possibly leading to reworked weathering crust reservoir;and(4)liable to form inner reservoirs.The volcanic reservoirs can be concluded into four hydrocarbon accumulation patterns,i.e.,self-generating&self-storing in paleo-uplift and vertical migration,self-generating&self-storing in paleo-uplift and lateral migration,young-generating&old-storing in fault zone and vertical migration,and young-generating&old-storing in paleo-uplift and lateral migration.Future exploration will focus on the effective source rock development and hydrocarbon supply zones and the selfgenerating&self-storing and young-generating&old-storing patterns.The exploration prospects are determined to be the Ludong-Wucaiwan-Baijiahai slope belt and the southern slope belt of the Shaqi uplift(self-generating&self-storing pattern)in eastern Junggar,and the fault and nasal arch zone at the northwestern margin and the nasal arch zone(deep and large structure)in the Luxi area(younggenerating&old-storing pattern)in western Junggar. | Xiaozhi Wu Qiulin Guo Wei Zhang Dengfa He Xuefeng Qi Di Li | 2021 | Journal of Earth Science2021，32，4： | 1 |
| 7 | Seamless and early gap healing of osteochondral defects by autologous mosaicplasty combined with bioactive supramolecular nanofiber-enabled gelatin methacryloyl(BSN-GelMA)hydrogel显示文摘Autologous mosaicplasty is a common approach used to treat osteochondral defects in clinical practice.Gap integration between host and transplanted plugs requires bone tissue reservation and hyaline cartilage regeneration without uneven surface,graft necrosis and sclerosis.However,poor gap integration is a serious concern,which eventually leads to deterioration of joint function.To deal with such complications,this study has developed a strategy to effectively enhance integration of the gap region following mosaicplasty by applying injectable bioactive supramolecular nanofiber-enabled gelatin methacryloyl(GelMA)hydrogel(BSN-GelMA).A rabbit osteochondral defect model demonstrated that BSN-GelMA achieved seamless osteochondral healing in the gap region between plugs of osteochondral defects following mosaicplasty,as early as six weeks.Moreover,the International Cartilage Repair Society score,histology score,glycosaminoglycan content,subchondral bone volume,and collagen II expression were observed to be the highest in the gap region of BSN-GelMA treated group.This improved outcome was due to bio-interactive materials,which acted as tissue fillers to bridge the gap,prevent cartilage degeneration,and promote graft survival and migration of bone marrow mesenchymal stem cells by releasing bioactive supramolecular nanofibers from the GelMA hydrogel.This study provides a powerful and applicable approach to improve gap integration after autologous mosaicplasty.It is also a promising off-the-shelf bioactive material for cell-free in situ tissue regeneration. | Hongwei Wu Yuna Shang Wei Sun Xinyi Ouyang Wenyan Zhou Jieji Lu Shuhui Yang Wei Wei Xudong Yao g Xiaozhao Wang Xianzhu Zhang Yishan Chen Qiulin He Zhimou Yang Hongwei Ouyang | 2023 | Bioactive Materials2023，，1： | 1 |

| 12 | Mesh model building and migration and accumulation simulation of 3D hydrocarbon carrier system显示文摘Migration and accumulation simulation of oil and gas in carrier systems has always been a difficult subject in the quantitative study of petroleum geology. In view of the fact that the traditional geological modeling technology can not establish the interrelation of carriers in three dimensional space, we have proposed a hybrid-dimensional mesh modeling technology consisting of body(stratum), surfaces(faults and unconformities), lines and points, which provides an important research method for the description of geometry of sand bodies, faults and unconformities, the 3 D geological modeling of complex tectonic areas, and the simulation of hydrocarbon migration and accumulation. Furthermore, we have advanced a 3 D hydrocarbon migration pathway tracking method based on the hybrid-dimensional mesh of the carrier system. The application of this technology in western Luliang Uplift of Junggar Basin shows that the technology can effectively characterize the transport effect of fault planes, unconformities and sand bodies, indicate the hydrocarbon migration pathways, simulate the process of oil accumulation, reservoir adjustment and secondary reservoir formation, predict the hydrocarbon distribution. It is found through the simulation that the areas around the paleo-oil reservoir and covered by migration pathways are favorable sites for oil and gas distribution. | GUO Qiulin LIU Jifeng CHEN Ningsheng WU Xiaozhi REN Hongjia WEI Yanzhao CHEN Gang GONG Deyu YUAN Xuanjun | 2018 | Petroleum Exploration and Development2018，45，6： | 0 |
| 13 | Ar-plasma enhanced copper-nickel alloy catalysis for ammonia synthesis显示文摘Ammonia(NH_(3))synthesis via electrocatalytic nitrogen reduction generally suffers from low NH_(3)yield and faradaic efficiency.Compared with activating stable,low-solubility N_(2),the electrochemical conversion of nitrates to ammonia provides a more reasonable route for NH_(3)production.Herein,we introduce Ar-plasma to enhance the interaction between copper-nickel alloys and carbon substrate to improve the performance of NH_(3)production.The NH_(3)faradaic efficiency from nitrate is nearly 100%and the yield rate is over 6000μgNH_(3)cm^(−2)h^(−1).DFT(density functional theory)calculation reveals the high performance of Cu_(50)Ni_(50)originates from the lower energy barrier on the reaction path and the closer position to the Fermi level of the d-band center.This work offers a promising strategy for plasma-modified electrocatalyst to promote ammonia synthesis via nitrate reduction. | Zhou Yimeng Lv Jiabao Peng Yaqi Lin Xiaoqing Lv Xingjie Ye Qiulin Liu Shaojun Wu Angjian Li Xiaodong | 2022 | Waste Disposal and Sustainable Energy2022，4，2： | 0 |
| 14 | Electrocatalytic CO_(2) reduction to C_(2)H_(4): From lab to fab显示文摘The global concerns of energy crisis and climate change,primarily caused by carbon dioxide(CO_(2)),are of utmost importance.Recently,the electrocatalytic CO_(2) reduction reaction(CO_(2)RR) to high value-added multi-carbon(C_(2+)) products driven by renewable electricity has emerged as a highly promising solution to alleviate energy shortages and achieve carbon neutrality.Among these C_(2+) products,ethylene(C_(2)H_(4))holds particular importance in the petrochemical industry.Accordingly,this review aims to establish a connection between the fundamentals of electrocatalytic CO_(2) reduction reaction to ethylene(CO_(2)RRto-C_(2)H_(4)) in laboratory-scale research(lab) and its potential applications in industrial-level fabrication(fab).The review begins by summarizing the fundamental aspects,including the design strategies of high-performance Cu-based electrocatalysts and advanced electrolyzer devices.Subsequently,innovative and value-added techniques are presented to address the inherent challenges encountered during the implementations of CO_(2)RR-to-C_(2)H_(4) in industrial scenarios.Additionally,case studies of the technoeconomic analysis of the CO_(2)RR-to-C_(2)H_(4) process are discussed,taking into factors such as costeffectiveness,scalability,and market potential.The review concludes by outlining the perspectives and challenges associated with scaling up the CO_(2)RR-to-C_(2)H_(4) process.The insights presented in this review are expected to make a valuable contribution in advancing the CO_(2)RR-to-C_(2)H_(4) process from lab to fab. | Zeyu Guo Fabao Yang Xiaotong Li Huiwen Zhu Hainam Do Kam Loon Fow Jonathan D.Hirst Tao Wu Qiulin Ye Yaqi Peng Hao Bin Wu Angjian Wu Mengxia Xu | 2024 | Journal of Energy Chemistry2024，90，3： | 0 |
| 15 | Study on Sustained-Release Pesticides Blended with Fosthiazate-Stearic Acid/Expanded Perlite显示文摘The low utilization rate of pesticides makes the migration of pesticides in water and soil,which brings great harm to the ecosystem.The development of pesticide carriers with good drug loading capacity and release control abil-ity is an effective method to realize effective utilization of pesticides and reduce pesticide losses.In this work,fosthiazate-stearic acid/expanded perlite sustained-release particles were successfully prepared by vacuum impregnation using expanded perlite(EP)as carrier,fosthiazate(FOS)as model pesticide and stearic acid(SA)as hydrophobic matrix.The structure and morphology of the samples were studied by BET,FT-IR,TGA,XRD,DSC and SEM.The effects of different mass ratios of FOS to SA on loading capacity and release rate at 24 h were investigated.The sustained release behavior of FOS-SA/EP at different temperatures and pH values was investigated by static dialysis bag method.The results showed that FOS and SA were adsorbed in EP pores by physical interaction.With the mass ratios of FOS to SA decreasing from 7:3 to 3:7,the 24 h release rate of FOS-SA/EP decreased from 18.77%to 8.05%,and the drug loading decreased from 461.32 to 130.99 mg/g.FOS-SA/EP showed obvious temperature response at 25℃,30℃ and 35℃,the cumulative release rate(CRR)of 200 h were 33.38%,41.50%and 51.17%,respectively.When pH=5,the CRR of FOS was higher than that of pH=7,and the CRR of FOS for 200 h were 49.01%and 30.12%,respectively.At different temperatures and pH=5,the release mechanism of FOS-SA/EP belongs to the Fickian diffusion mechanism;When pH=7,the diffusion mechanism is dominant,and the dissolution mechanism is complementary. | Huimin Huang Zijun Wu Zhijian Zhou Qiulin Xu Jie Yan Qiaoguang Li | 2023 | Journal of Renewable Materials2023，11，1： | 0 |
| 16 | Theranostic Gold Nanoclusters for NIR-II Imaging and Photodynamic Therapy显示文摘Fluorescence imaging in the second near-infrared window(NIR-II,1000―1700 nm)has demonstrated tremendous promise for biomedical applications,with its extraordinarily high resolution and deep tissue penetration.Ultrasmall gold nanoclusters(AuNCs)have shown unique features for NIR-II imaging,such as photostability and biocompatibility,as compared to organic NIR-II molecules or other inorganic NIR-II nanoparticles.Here,we report the first-in-class protein-capped ultrasmall AuNCs(BSA-AuNCs,BSA=bovine serum albumin)for simultaneous NIR-II imaging and photodynamic therapy.The BSA-AuNCs show a uniform size,high quantum yield and excellent photostability,display a high accumulation and long retention in 4T1 tumor,and are used for clear imaging of blood vessels and lymph nodes.Moreover,laser irradiation of these AuNCs can rapidly trigger ROS generation,leading to effective inhibition of tumor cell growth in vitro and in vivo.This study demonstrates the feasibility of a protein-capped ultrasmall AuNCs platform for theranostic applications by combining NIR-II imaging and photodynamic cancer therapy. | TANG Lin ZENG Xiaodong ZHOU Hui GUI Conghao LUO Qiulin ZHOU Wenyi WU Jing LI Qianqian LI Yang XIAO Yuling | 2021 | Chemical Research in Chinese Universities2021，37，4： | 0 |
| 17 | Theory, Technology and Practice of Unconventional Petroleum Geology显示文摘0 INTRODUCTION The breakthroughs in unconventional petroleum have a great impact on world petroleum industry and innovation in petroleum geology(Dou et al,2022;Jia,2017;Zou et al.,2015b,2014a;Yerkin,2012;Pollastro,2007;Schmoker,1995).The exploration and development evolution from conventional petroleum to unconventional petroleum and more and more frequent industrial activities of exploring petroleum inside sources kitchen have deepened theoretical understanding of unconventional petroleum geology and promoted technical research and development(Jia et al.,2021,2017;Jin et al.,2021;Zhao W Z et al.,2020;Ma Y S et al.,2018,2012;Zou et al.,2018b,2016,2009;Dai et al.,2012).We have introduced and extended the theory of continuous hydrocarbon accumulation since 2008 and published several papers/books(in Chinese and English)with respect to unconventional petroleum geology since 2009,basically forming the theoretical framework for this discipline(Yang et al.,2022a,2021a,2019a,,2015a;Zou et al.,2019c,2017b,2014a,,2013a).In this paper,we present the background of unconventional petroleum geology,review the latest theoretical and technological progress in unconventional petroleum geology,introduce relevant thinking and practices in China,and explore the pathway of unconventional petroleum revolution and multi-energy coordinated development in super energy basins,hopefully to promote the unconventional petroleum geology and industry development. | Caineng Zou Zhi Yang Guosheng Zhang Rukai Zhu Shizhen Tao Xuanjun Yuan Lianhua Hou Dazhong Dong Qiulin Guo Yan Song Qiquan Ran Zhen Qiu Songtao Wu Feng Ma Bin Bai Lan Wang Bo Xiong Songqi Pan Hanlin Liu Xiaoni Wang | 2023 | Journal of Earth Science2023，34，4： | 0 |
| 18 | Quantitative Trait Loci(QTL)Mapping and Marker Analysis of Fatty Acids in Peanut显示文摘Peanut,with high oil content,has been a major oil and food crop globally.The compositions of the fatty acids are the common factors in determining the oil quality.In the present study,an F2 segregated population with 140 individuals derived from the cross of Weihua8(a cultivar)and 12L49(a line with high oleic acid concentration)was used to construct a genetic map and conduct QTL mapping analysis.A total of 103 polymorphic SSR primers were utilized for genotyping the RILs and finally generating the SSR loci.Within the 103 SSR loci,a genetic linkage map,covering a total length of 3592.35 cM of the whole peanut genome,was constructed.Based on the genetic map,sixteen QTLs located on nine linkage groups related to peanut fatty acids were finally identified.Among them,four QTLs were detected associated with various traits simultaneously,which showed genetic stability in relation to fatty acids of peanut.Except for the QTLs for oleic acid,linoleic acid,and linolenic acid,three novel QTLs for arachidic acid and behenic acid were also detected.These QTLs might be helpful for further fine mapping analysis and marker-assisted selection of fatty acids in peanut. | Xiao Han Songnan Yang Xueying Li Qiulin Wu Yongyi Xing Jun Zhang Fenglou Ling | 2023 | Phyton-International Journal of Experimental Botany2023，92，9： | 0 |
| 19 | Arginine vasopressin induces ferroptosis to promote heart failure via activation of the V1aR/CaN/NFATC3 pathway显示文摘Arginine vasopressin(AVP)is a key contributor to heart failure(HF),but the underlying mechanisms remain unclear.In the present study,a mouse model of HF and human cardiomyocyte(HCM)cells treated with dDAVP are generated in vivo and in vitro,respectively.Hematoxylin and eosin(HE)staining is used to evaluate the morphological changes in the myocardial tissues.A colorimetric method is used to measure the iron concentration,Fe^(2+)concentration and malondialdehyde(MDA)level.Western blot analysis is used to examine the protein levels of the V1a receptor(V1aR),calcineurin(CaN),nuclear factor of activated T cells isoform C3(NFATC3),glutathione peroxidase 4(GPX4)and acyl-CoA synthase long chain family member 4(ACSL4).Immunoprecipitation(IP)and luciferase reporter assays are performed to determine the interaction between NFATC3 and ACSL4.Both in vivo and in vitro experiments reveal that the V1aR-CaN-NFATC3 signaling pathway and ferroptosis are upregulated in HFs,which are verified by the elevated protein levels of V1aR,CaN,NFATC3 and ACSL4;reduced GPX4 protein level;and enhanced Fe^(2+)and MDA levels.We further find that inhibiting NFATC3 by suppressing the V1aR/CaN/NFATC3 pathway via V1aR/CaN inhibitors or sh-NFATC3 not only alleviates HF but also inhibits AVP-induced ferroptosis.Mechanistically,sh-NFATC3 significantly reverses the increase in AVP-induced ACSL4 protein level,Fe^(^(2+))concentration,and MDA level by directly interacting with ACSL4.Our results demonstrate that AVP enhances ACSL4 expression by activating the V1aR/CaN/NFATC3 pathway to induce ferroptosis,thus contributing to HF.This study may lead to the proposal of a novel therapeutic strategy for HF. | Zhiyong Wu Hua Jiang Qiulin Yin Zhifeng Zhang Xuanlan Chen | 2024 | Acta Biochimica et Biophysica Sinica2024，56，3： | 0 |
| 20 | Preparation of Iron-Pillared Bentonite/Oyster Shell Composite and Phosphate Adsorption in Water显示文摘Iron-pillared bentonite(FB)was prepared by Fe(III)modified bentonite,and then the composites(FB-OS)were prepared by iron-pillared bentonite and oyster shell powder.The composites were characterized by FTIR,SEM,TGA,and EDS,and the phosphorus removal test was carried out.The results showed that FB-OS contained a large amount of CaO.Its structure was compact,but there were gaps in it.The maximum bending stress and compressive strength were 43.7 N and 0.927 MPa,respectively.The phosphorus removal test showed that the phosphorus removal rate of FB-OS was more than 90%,and measured the maximum adsorption capacity was 48.31 mg/g.A large amount of spherical products were produced on the surface and inside of FB-OS after phos-phorus removal,it was speculated that spherical products were amorphous calcium phosphate in the paper.Ana-lysis indicated that there was chemical adsorption during phosphorus removal.The kinetic equation of phosphorus adsorption by FB-OS was qt=10:193t/1+2:574t (R^(2)=0.995).The adsorption rate was mainly controlled by outerfilm diffusion and intraparticle diffusion. | Zhijian Zhou Jie Yan Xinxiang Du Qiulin Xu Zijun Wu Jinlan Yang Xitong Fang Qiuling Zhong Qiaoguang Li | 2023 | Journal of Renewable Materials2023，11，9： | 0 |
