| 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 |
| 2 | Effect of pitch angle on initial stage of a transport airplane ditching显示文摘Airworthiness regulations require that the transport airplane should be proved to ensure the survivability of the ditching for the passengers. The planned ditching of a transport airplane on the calm water is numerically simulated. The effect of pitch angle on the impact characteristics is especially investigated by a subscaled model. The Reynolds-averaged Navier-Stokes (RANS) equations of unsteady compressible flow are solved and the realizable j-e equations are employed to model the turbulence. The transformation of the air-water interface is tracked by volume of fluid (VOF) model. The motion of the rigid body is modeled by dynamic mesh method. The initial ditching stage of the transport airplane is analyzed in detail. The numerical results show that as the pitching angle increases, the maximal normal force decreases and the pitching motion becomes much gentler. The aft fuselage would be sucked down by the water and lead to pitching up, whereas the low horizontal tail prevents this trend. Consequently, the transport aircraft with low horizontal tail should ditch on the water at an angle between 10 and 12 as a recommendation. | Guo Baodong Liu Peiqing Qu Qiulin Wang Jiawen | 2013 | Chinese Journal of Aeronautics2013，26，1： | 18 |
| 3 | Long-term changes of phytoplankton community in Xiagu waters of Xiamen,China显示文摘Long-term changes of phytoplankton community by water sampling method in Xiagu Sea waters of Xiamen,China,were investigated in this study.Species composition of the phytoplankton community in these waters changed greatly since the 1950s.The numbers of Dinophyta species increased significantly,although Bacillariophyta species are generally dominant.The succession of dominant species in phytoplankton community is obvious: large-size dominant species such as Biddulphia sinensis of the 1950s were gradually replaced by small-size ones such as Cyclotella striata and Nitzschia closterium,and species that still maintain dominant such as Skeletonema costatum are also small ones,leading the whole phytoplankton community of smaller size.Cell density of phytoplankton community increased greatly,among which cell density of the most dominant species Skeletonema costatum have been increasing in exponent function.Margalef index of phytoplankton community decreased,indicating decline of biodiversity of the community,and dominant character of Skeletonema costatum increased.Generally,the structure of the entire phytoplankton community is becoming more and more singular and unstable,which makes the occurrence of red tides more frequent.The succession in the phytoplankton community is related to the long-term changes in marine environment,influenced by human activities and global climate changes,especially the increases of nutrient content. | CHEN Baohong XU Zhuhua ZHOU Qiulin CHEN Changping GAO Yahui YANG Shengyun JI Weidong | 2010 | Acta Oceanologica Sinica2010，29，6： | 14 |

| 5 | Multifunctional roles of carbon-based hosts for Li-metal anodes:A review显示文摘With its high theoretical capacity,lithium(Li)metal is recognized as the most potential anode for realizing a high-performance energy storage system.A series of questions(severe safety hazard,low Coulombic efficiency,short lifetime,etc.)induced by uncontrollable dendrites growth,unstable solid electrolyte interface layer,and large volume change,make practical application of Li-metal anodes still a threshold.Due to their highly appealing properties,carbon-based materials as hosts to composite with Li metal have been passionately investigated for improving the performance of Li-metal batteries.This review displays an overview of the critical role of carbon-based hosts for improving the comprehensive performance of Li-metal anodes.Based on correlated mainstream models,the main failure mechanism of Li-metal anodes is introduced.The advantages and strategies of carbon-based hosts to address the corresponding challenges are generalized.The unique function,existing limitation,and recent research progress of key carbon-based host materials for Li-metal anodes are reviewed.Finally,a conclusion and an outlook for future research of carbon-based hosts are presented.This review is dedicated to summarizing the advances of carbon-based materials hosts in recent years and providing a reference for the further development of carbonbased hosts for advanced Li-metal anodes. | Xiaolin Yan Liang Lin Qiulin Chen Qingshui Xie Baihua Qu Laisen Wang Dong-Liang Peng | 2021 | Carbon Energy2021，3，2： | 8 |
| 6 | Advanced hydrogels for the repair of cartilage defects and regeneration显示文摘Cartilage defects are one of the most common symptoms of osteoarthritis(OA),a degenerative disease that affects millions of people world-wide and places a significant socio-economic burden on society.Hydrogels,which are a class of biomaterials that are elastic,and display smooth surfaces while exhibiting high water content,are promising candidates for cartilage regeneration.In recent years,various kinds of hydrogels have been developed and applied for the repair of cartilage defects in vitro or in vivo,some of which are hopeful to enter clinical trials.In this review,recent research findings and developments of hydrogels for cartilage defects repair are summarized.We discuss the principle of cartilage regeneration,and outline the requirements that have to be fulfilled for the deployment of hydrogels for medical applications.We also highlight the development of advanced hydrogels with tailored properties for different kinds of cartilage defects to meet the requirements of cartilage tissue engineering and precision medicine. | Wei Wei Yuanzhu Ma Xudong Yao Wenyan Zhou Xiaozhao Wang Chenglin Li Junxin Lin Qiulin He Sebastian Leptihn Hongwei Ouyang | 2021 | Bioactive Materials2021，6，4： | 8 |
| 7 | Activity and hydrothermal stability of CeO_2–ZrO_2–WO_3 for the selective catalytic reduction of NO_x with NH_3显示文摘A series of CeO_2–ZrO_2–WO_3(CZW)catalysts prepared by a hydrothermal synthesis method showed excellent catalytic activity for selective catalytic reduction(SCR)of NO with NH_3 over a wide temperature of 150–550°C.The effect of hydrothermal treatment of CZW catalysts on SCR activity was investigated in the presence of 10% H_2O.The fresh catalyst showed above 90% NO_x conversion at 201–459°C,which is applicable to diesel exhaust NO_x purification(200–440°C).The SCR activity results indicated that hydrothermal aging decreased the SCR activity of CZW at low temperatures(below 300°C),while the activity was notably enhanced at high temperature(above 450°C).The aged CZW catalyst(hydrothermal aging at 700°C for 8 hr)showed almost 80% NO_x conversion at 229–550°C,while the V_2O_5–WO_3/TiO_2 catalyst presented above 80% NO_x conversion at 308–370°C.The effect of structural changes,acidity,and redox properties of CZW on the SCR activity was investigated.The results indicated that the excellent hydrothermal stability of CZW was mainly due to the CeO_2–ZrO_2 solid solution,amorphous WO_3 phase and optimal acidity.In addition,the formation of WO_3 clusters increased in size as the hydrothermal aging temperature increased,resulting in the collapse of structure,which could further affect the acidity and redox properties. | Zhongxian Song Ping Ning Qiulin Zhang Hao Li Jinhui Zhang Yancai Wang Xin Liu Zhenzhen Huang | 2016 | Journal of Environmental Sciences2016，28，4： | 7 |
| 8 | Catalytic methanol decomposition to carbon monoxide and hydrogen over Pd/CeO_2-ZrO_2-La_2O_3 with different Ce/Zr molar ratios显示文摘The catalytic behaviors of Pd (1.4 wt%) catalysts supported on CeO2-ZrO2-La2O3 mixed oxides with different Ce/Zr molar ratios were investigated for methanol decomposition. Nitrogen adsorption-desorption (BET), X-ray photoelectron spectroscopy (XPS), H2 temperature-programmed reduction (H2-TPR), X-ray diffraction (XRD) and Pd dispersion analysis were used for their characterization. Pd/Ce0.76Zr0.18 La0.06O1.97 catalyst showed the highest BET surface area, best Pd dispersion capability and strongest metal-support interaction. Moreover, XPS showed that there was lattice defect oxygen or mobile oxygen. According to the result of O 1s measurements the lattice defect oxygen or mobile oxygen helped to maintain Pd in a partly oxidized state and increased the activity for methanol decomposition. The Pd/Ce0.76Zr0.18La0.06O1.97 catalyst exhibited the best activity. A 100% conversion of methanol was achieved at around 260℃, which was about 20-40℃ lower than other | Hairong Wang Yaoqiang Chen Qiulin Zhang Qingchao Zhu Maochu Gong Ming Zhao | 2009 | Journal of Natural Gas Chemistry2009，18，2： | 6 |
| 9 | Homogeneous bottom-growth of lithium metal anode enabled by double-gradient lithiophilic skeleton显示文摘Lithium(Li) metal is considered as the most promising anode material for the next-generation high performance Li batteries.However,the uncontrollable dendritic growth impedes its commercial application.Herein,we design a 3 D Si@carbon nanofibers(CNFs)@ZnO-ZnO-Cu skeleton(SCZ) for guiding the homogeneous bottom-growth of Li metal.The top LixSi@CNFs and bottom LiyZn@CNFs layers could form conductivity and overpotential gradient to avoid the 'top-growth' of Li metal.Moreover,the top lithiophilic LixSi@CNFs layer could regulate the nucleation and deposition of Li-ions even if the lithium dendrites grow out of the skeleton under high capacity Li deposition(30 mAh cm^(-2)).As a result,the SCZ-Li||LiFePO_(4) full cell delivers a high capacity of ~104 mAh g^(-1)(~94.82% capacity retention) after 2000 cycles at 5 C, elucidating the potential application of the 3 D double-gradient Li metal composite anode. | Li Zhang Hongfei Zheng Ben Liu Qingshui Xie Qiulin Chen Liang Lin Jie Lin Baihua Qu Laisen Wang Dong-Liang Peng | 2021 | Journal of Energy Chemistry2021，30，6： | 5 |
| 10 | 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 |
| 11 | End of the First Demographic Dividend and Possible Labor Market Response in China and Other Asian Countries(Regions)显示文摘This paper sheds light on the nexus of age compositional shifts and the generation of the first demographic dividend over the past several decades in China,and also discusses how this dividend could be extended.We first estimate how long China's first demographic dividend will last and then compare the computed results for China with those for other selected Asian countries in order to place the Chinese case in a wider perspective.Furthermore,in view of the possibility that China's first demographic dividend will turn negative in 2014,we offer insight into how and to what extent China's labor market needs to adjust and how much labor income must increase for the first demographic dividend to remain positive up to year2050.For this goal to be achieved,the labor income age profile needs to be shifted to a considerable extent.We conduct an exercise in which the 2007 peak labor income age of 32years is shifted to 40years.In the case of the elderly,this implies an annual labor income growth of 3.1 percent over the period of 39 years.Throughout this paper,we draw on a variety of computed results derived from the Chinese component of the global'National Transfer Accounts'project. | Naohiro Ogawa Qiulin Chen | 2013 | China & World Economy2013，21，2： | 5 |
| 12 | Evolution of urban black and odorous water:The characteristics of microbial community and driving-factors显示文摘Urban black blooms that are primarily caused by organic carbon are deleterious environmental problems.However,detailed studies on the microbial characteristics that form urban black blooms are lacking.In this study,we observed the composition,diversity,and function of bacterial community in the overlying water and sediments during the occurrence and remediation of urban black blooms using high-throughput 16S rRNA gene amplicon sequencing analysis.First,we found that pivotal consortia in the overlying water increased significantly during the formation of black blooms,including the genera Acidovorax,Brevundimonas,Pusillimonas,and Burkholderiales involved in the degradation of refractory organics,as well as the genera Desulfovibrio,Dechloromonas,and Rhizobium related to the production of black and odorous substances.An RDA analysis revealed that chemical oxygen demand,dissolved oxygen,and oxidation reduction potential were related to the changes in microbial community composition.Furthermore,aeration was found to accelerate the removal of ammonia nitrogen and enhance the function of microbial community by stimulating the growth of order Planktomycetes during the remediation of black blooms,but aeration substantially damaged the microbial diversity and richness.Therefore,the health of the aquatic ecosystem should be comprehensively considered when aeration is applied to restore polluted waterbodies.Notably,we observed a large number of pathogenic bacteria in urban black blooms,which emphasizes the importance of treating domestic sewage so that it is harmless.Together,these findings provide new insights and a basis to prevent and manage urban black blooms. | Dan Zhang Huilan Yang Shuhuan Lan Chen Wang Xudong Li Yunxiao Xing Hua Yue Qiulin Li Ling Wang Yifei Xie | 2022 | Journal of Environmental Sciences2022，34，2： | 4 |
| 13 | 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 |
| 14 | Interfacial engineering of Ni/V2O3 for hydrogen evolution reaction显示文摘Electrocatalytic water splitting offers a sustainable route for hydrogen production,enabling the clean and renewable alternative energy system of hydrogen economy.The scarcity and high-cost of platinum-group-metal(PGM)materials urge the exploration of high-performance non-PGM electrocatalysts.Herein,a unique hierarchical structure of NiA/2O3 with extraordinary electrocatalytic performance(e.g.t overpotentials as low as 22 mV at 20 mA·cm^-2 and 94 mV at 100 mA·cm^-2)toward hydrogen evolution reaction in alkaline electrolyte(1 M KOH)is reported.The investigation on the hierarchical NiA/2O3 with a bimodal size-distribution also offers insight of interfacial engineering that only proper NiA/2O3 interface can effectively improve H20 adsorption,H20 dissociation as well as H adsorption,for an efficient hydrogen production. | Yang Chen Yuan Rao Rongzhi Wang Yanan Yu Qiulin Li Shujuan Bao Maowen Xu Qin Yue Yanning Zhang Yijin Kang | 2020 | Nano Research2020，13，9： | 3 |
| 15 | Starch-based Surface-sizing Agents in Paper Industry:An Overview显示文摘Natural starch is an abundant and inexpensive polysaccharide biopolymer that is widely used as a surface-sizing agent in the paper industry.The surface sizing of paper improves its water and abrasion resistance,as well as its physical strength and printing adaptability.However,natural starch presents some disadvantages,such as high viscosity,poor fluidity,poor filmforming properties,and easy coagulation.Therefore,starch is usually modified and blended with various components to achieve better sizing performance.This article reviews approaches for the surface sizing of paper and modification of starch using enzymes or chemical methods,such as oxidation,cationization,and graft copolymerization.This article also discusses the application of starch-based multiphase systems(obtained by blending starch with various components)as surface-sizing agents. | Qiulin Wei Hao Zheng Mengni Zhu Xiao Han Yao Li Jinghui Zhou | 2021 | Paper And Biomaterials2021，6，4： | 2 |
| 16 | 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 |
| 17 | Impact of small-world topologies on broadcasting for wireless sensor networks显示文摘Broadcasting is an important operation and been widely used in wireless sensor networks (WSNs). These networks are power constrained as nodes operate with limited battery power. Wireless sensor networks are spatial graphs that have much more clustered and much high path-length characteristics. After considering energyeffcient broadcasting in such networks, by combining the small-world characteristic of WSNs and the properties of ant algorithm to quickly identify an optimal path, small-world power-aware broadcast algorithm is introduced and evaluated. Given different densities of network, simulation results show that our algorithm significantly improves life of networks and also reduces communication distances and power consumption. | Jiang Nan Yang Shuqun Zhou Liang Ding Qiulin | 2009 | Journal of Systems Engineering and Electronics2009，20，1： | 2 |

| 19 | The potential distribution of adult Antarctic krill in the Amundsen Sea显示文摘Antarctic krill is the key species of ecological system in the Amundsen Sea.At present,the suitable distribution is unobtainable by scientifi c surveys or data from the fi shery.In this paper,the maximum entropy algorithm(Maxent)was used to obtain the potential distribution of adult Antarctic krill in order to provide useful information and reasonable reference for the policy on protecting potential krill habitats around the Amundsen Sea.Occurrence points and 17 environmental variables were used to simulate the distributions.Results show that the high and moderate suitable habitats lie between 65°S and 72°S in the Amundsen Sea.The high suitable habitat accounts for 8.1%of the total area of the Amundsen Sea.The sea ice persistence(ICE),total phytoplankton(PHYC),and the minimum value of dissolved iron(Fe_min)are the three dominant contributors to the model.Results from the response curves show that Antarctic krill preferred habitats with ICE of 0.42-0.93,PHYC of 2.48-2.77 mmol/m^(3) and Fe_min of(7.10×10^(-5))-(9.45×10^(-5))mmol/m 3.Positive trends existed in the PHYC of the high and moderate suitable habitat,and a positive trend existed in the Fe_min of moderate suitable habitat.However,the probability of presence of Antarctic krill will decrease if the increase of the PHYC and Fe_min continues. | Jianlong FENG Lulu LIU Qiulin LIU Liang ZHAO | 2022 | Journal of Oceanology and Limnology2022，40，4： | 1 |
