| 1 | ZIKA virus isolated from mosquitoes:a field and laboratory investigation in China,2016显示文摘A field investigation of arboviruses was conducted in Dejiang, Guizhou Province in the summer of 2016. A total of 8,795 mosquitoes, belonging to four species of three genera, and 1,300 midges were collected. The mosquito samples were identified on site according to their morphology, and the pooled samples were ground and centrifuged in the laboratory. The supernatant was incubated with mosquito tissue culture cells(C6/36) and mammalian cells(BHK-21) for virus isolation. The results indicated that 40%(3,540/8,795) were Anopheles sinensis, 30%(2,700/8,795) were Culex pipiens quinquefasciatus, and 29%(2,530/8,795)were Armigeres subbalbeatus. Furthermore, a total of eight virus isolates were obtained, and genome sequencing revealed two Zika viruses(ZIKVs) isolated from Culex pipiens quinquefasciatus and Armigeres subbalbeatus, respectively; three Japanese encephalitis viruses(JEVs) isolated from Culex pipiens quinquefasciatus; two Banna viruses(BAVs) isolated from Culex pipiens quinquefasciatus and Anopheles sinensis, respectively; and one densovirus(DNV) isolated from Culex pipiens quinquefasciatus.The ZIKVs isolated from the Culex pipiens quinquefasciatus and Armigeres subbalbeatus mosquitoes represent the first ZIKV isolates in China's Mainland. This discovery presents new challenges for the prevention and control of ZIKV in China, and prompts international cooperation on this global issue. | Shihong Fu Song Song Hong Liu Yuanyuan Li Xiaolong Li Xiaoyan Gao Ziqian Xu Guoping Liu Dingming Wang Zhenzao Tian Jingzhu Zhou Ying He Wenwen Lei Huanyu Wang Bin Wang Xiaoqing Lu Guodong Liang | 2017 | Science China(Life Sciences)2017，60，12： | 25 |
| 2 | Antioxidant effects of the orientin and vitexin in Trollius chinensis Bunge in D-galactose-aged mice显示文摘Total flavonoids are the main pharmaceutical components of Trollius chinensis Bunge, and orientin and vitexin are the monomer components of total flavonoids in Trollius chinensis Bunge. In this study, an aged mouse model was established through intraperitoneal injection of D-galactose for 8 weeks, followed by treatment with 40, 20, or 10 mg/kg orientin, vitexin, or a positive control (vitamin E) via intragastric administration for an additional 8 weeks. Orientin, vitexin, and vitamin E improved the general medical status of the aging mice and significantly increased their brain weights. They also produced an obvious rise in total antioxidant capacity, superoxide dismutase, catalase, and glutathione peroxidase levels in the serum, and the levels of superoxide dismutase, catalase and glutathione peroxidase, Na+-K+-ATP enzyme, and Ca2+-Mg2+-ATP enzyme in the liver, brain and kidneys. In addition, they significantly reduced malondialdehyde levels in the liver, brain and kidney and lipofuscin levels in the brain. They also significantly improved the neuronal ultrastructure. The 40 mg/kg dose of orientin and vitexin had the same antioxidant capacity as vitamin E. These experimental findings indicate that orientin and vitexin engender anti-aging effects through their antioxidant capacities. | Fang An Guodong Yang Jiaming Tian Shuhua Wang | 2012 | Neural Regeneration Research2012，7，33： | 20 |
| 3 | Development and industrial application of ultra-fast cooling technology显示文摘A new-generation TMCP(NG-TMCP) with ultra fast cooling(UFC) as core technique was suggested instead of the conventional TMCP in which some problems are to be solved.And the ultra fast cooling technology has been successfully applied to the plate rolling production in Shouqin Metal Materials Co.Ltd.Industrial trials are reported for the production of X70 pipeline steels(about 70000 t) under UFC conditions.Pipeline steels with reasonably good properties have been produced on an industrial scale.UFC can improve the temperature uniformity,the mechanical properties and the plate profile of X70 pipeline steel.The performance features of the trial plates can meet the standard of X70 pipeline steel.Spot test results have shown that the qualification rate of shape control,the performance and charpy impact properties for the trial plates are 95%,97% and 98%,respectively.The impact values of X70 pipeline steel at UFC mode exceed the standard requirements of X80 pipeline steel.The productivity is enhanced because cutting quantity of head and tail of the plate is reduced.The enhancement of control accuracy of the red back temperatures is favorable for industrial production of X70 pipeline steel.The reduced production of the steel-making has been industrially achieved,since a new composition was designed by reducing the vanadium content to less than 0.045 wt.%. | TIAN Yong TANG Shuai WANG BingXing WANG ZhaoDong WANG GuoDong | 2012 | Science China(Technological Sciences)2012，55，6： | 9 |

| 5 | Re-isolation of Wuxiang Virus from Wild Sandflies Collected from Yangquan County, China显示文摘We previously isolated a new species of the genus Phlebovirus from wild sandflies collected from Wuxiang County in central China,which named the Wuxiang virus(WUXV).In this study,we re-isolated the WUXV from wild sandflies collected from two villages in Yangquan County,China in 2019.Four virus isolates that caused cytopathic effects in BHK-21 cells were successfully isolated from sandfly specimens collected from chicken pens and sheep pens.Phylogenetic analyses of the L,M and S gene segments of the viruses revealed that the four virus strains represented the previously isolated WUXV.The minimum infection rate(MIR)of the virus isolated from the sheep pen was 3.21,and the MIR of the virus isolated from the chicken pen was 3.45.The positive rates of Wuxiang virus neutralizing antibodies in serum samples of local healthy people and domestic chickens were 8.7%(4/46)and 100%(4/4),respectively,suggesting that Wuxiang virus can infect human and animal.In view of the fact that Wuxiang virus is infectious to humans and animals and has a relatively wide geographical distribution in China,it is of great public health significance to strengthen the investigation and study on the infection status of Wuxiang virus in humans and animals. | Qinyan Wang Shihong Fu Jingxia Cheng Xiuyan Xu Jing Wang Bin Wu Xiaodong Tian Yan Li Ying He Fan Li Kai Nie Songtao Xu Bin Wang Huanyu Wang Xiaoqing Lu Guodong Liang | 2021 | Virologica Sinica2021，36，5： | 4 |
| 6 | IGF-Ⅱ and IGFBP-1 reversely regulate blastocyst implantation in mouse显示文摘Insulin-like growth factor (IGF)-Ⅱ and IGF binding protein (IGFBP)-1, members of IGF family, are important in the cyclic development of endometrium and the blastocyst implantation. In the present study, the indirect immunofluorescence showed that IGF- Ⅱ and IGFBP-1 were specifically expressed at the maternal-fetal interface. In a co-culture system, IGF-Ⅱ significantly enhanced the attachment and outgrowth of the blastocyst on monolayer of uterine epithelial cells, while IGFBP-1 did not affect the blastocyst attachment, but markedly inhibited the blastocyst outgrowth. The results of zymography showed that IGF- Ⅱ enhanced the activities of MMP-2 and MMP-9, while IGFBP-1 did not affect the activities of MMP-2 and MMP-9. In conclusion, the equilibrium between the invasion of tro-phoblast and the inhibition of deciduas may be regulated by the interaction between the IGF- Ⅱ -expressing invading cy-totrophoblast and maternal deciduas-derived IGFBP-1. | TIAN Yongqiang, TIE Guodong, CAO Yujing, ZHAO Xingxu & DUAN Enkui1.

| 7 | Sustainability Evaluation of Different Systems for Sea Cucumber(Apostichopus japonicus) Farming Based on Emergy Theory显示文摘Emergy analysis is effective for analyzing ecological economic systems. However, the accuracy of the approach is affected by the diversity of economic level, meteorological and hydrological parameters in different regions. The present study evaluated the economic benefits, environmental impact, and sustainability of indoor, semi-intensive and extensive farming systems of sea cucumber(Apostichopus japonicus) in the same region. The results showed that A. japonicus indoor farming system was high in input and output(yield) whereas pond extensive farming system was low in input and output. The output/input ratio of indoor farming system was lower than that of pond extensive farming system, and the output/input ratio of semi-intensive farming system fell in between them. The environmental loading ratio of A. japonicus extensive farming system was lower than that of indoor farming system. In addition, the emergy yield and emergy exchange ratios, and emergy sustainability and emergy indexes for sustainable development were higher in extensive farming system than those in indoor farming system. These results indicated that the current extensive farming system exerted fewer negative influences on the environment, made more efficient use of available resources, and met more sustainable development requirements than the indoor farming system. A. japonicus farming systems showed more emergy benefits than fish farming systems. The pond farming systems of A. japonicus exploited more free local environmental resources for production, caused less potential pressure on the local environment, and achieved higher sustainability than indoor farming system. | WANG Guodong DONG Shuanglin TIAN Xiangli GAO Qinfeng WANG Fang | 2015 | Journal of Ocean University of China2015，14，3： | 2 |
| 8 | Litter Decomposition of Emergent Plants along an Elevation Gradient in Wetlands of Yunnan Plateau,China显示文摘The decomposition of plant litter is a key process in the flows of energy and nutrients in ecosystems. However, the response of litter decomposition to global climate warming in plateau wetlands remains largely unknown. In this study, we conducted a one-year litter decomposition experiment along an elevation gradient from 1891 m to 3260 m on the Yunnan Plateau of Southwest China, using different litter types to determine the influences of climate change, litter quality and microenvironment on the decomposition rate. The results showed that the average decomposition rate(K) increased from 0.608 to 1.152, and the temperature sensitivity of litter mass losses was approximately 4.98%/℃ along the declining elevation gradient. Based on a correlation analysis, N concentrations and C︰N ratios in the litter were the best predictors of the decomposition rate, with significantly positive and negative correlations, respectively. Additionally, the cumulative effects of decomposition were clearly observed in the mixtures of Scirpus tabernaemontani and Zizania caduciflora. Moreover, the litter decomposition rate in the water was higher than that in the sediment, especially in high-elevation areas where the microenvironment was significantly affected by temperature. These results suggest that future climate warming will have significant impacts on plateau wetlands, which have important functions in biogeochemical cycling in cold highland ecosystems. | LIU Guodong SUN Jinfang TIAN Kun YUAN Xingzhong AN Subang WANG Hang | 2017 | Chinese Geographical Science2017，27，5： | 2 |
| 9 | Spatial variation and driving mechanism of soil organic carbon components in the alluvial/sedimentary zone of the Yellow River显示文摘Alluviation and sedimentation of the Yellow River are important factors influencing the surface soil structure and organic carbon content in its lower reaches.Selecting Kaifeng and Zhoukou as typical cases of the Yellow River flooding area,the field survey,soil sample collection,laboratory experiment and Geographic Information System(GIS)spatial analysis methods were applied to study the spatial distribution characteristics and change mechanism of organic carbon components at different soil depths.The results revealed that the soil total organic carbon(TOC),active organic carbon(AOC)and nonactive organic carbon(NOC)contents ranged from 0.05–30.03 g/kg,0.01–8.86 g/kg and 0.02–23.36 g/kg,respectively.The TOC,AOC and NOC contents in the surface soil layer were obviously higher than those in the lower soil layer,and the sequence of the content and change range within a single layer was TOC>NOC>AOC.Geostatistical analysis indicated that the TOC,AOC and NOC contents were commonly influenced by structural and random factors,and the influence magnitudes of these two factors were similar.The overall spatial trends of TOC,AOC and NOC remained relatively consistent from the 0–20 cm layer to the 20–100 cm layer,and the transition between high-and low-value areas was obvious,while the spatial variance was high.The AOC and NOC contents and spatial distribution better reflected TOC spatial variation and carbon accumulation areas.The distribution and depth of the sediment,agricultural land-use type,cropping system,fertilization method,tillage process and cultivation history were the main factors impacting the spatial variation in the soil organic carbon(SOC)components.Therefore,increasing the organic matter content,straw return,applying organic manure,adding exogenous particulate matter and conservation tillage are effective measures to improve the soil quality and attain sustainable agricultural development in the alluvial/sedimentary zone of the Yellow River. | LI Guodong ZHANG Junhua ZHU Lianqi TIAN Huiwen SHI Jiaqi REN Xiaojuan | 2021 | Journal of Geographical Sciences2021，31，4： | 2 |
| 10 | Risk-taking path choice behaviors under ATIS in transportation networks with demand uncertainty显示文摘A new travel time reliability-based traffic assignment model is proposed to investigate the effects of an advanced transportation information system (ATIS) on drivers' risk-taking path choice behaviours in transportation networks with demand uncertainty. In the model, drivers are divided into two classes. The first class is not equipped with ATIS, while the second class is equipped with ATIS. Different risk-taking path choice behaviours of the two classes are studied, respectively. A corresponding mixed equilibrium traffic assignment model is formulated as a variational inequality problem in terms of path flows, which is solved by a heuristic solution algorithm. Numerical results indicate that the ATIS can influence the drivers' risk-taking path choice behaviours and the total system travel time in transportation networks with demand uncertainty. It is also found that under higher demand levels, the benefits of ATIS for network performance enhancement may be more obvious. | Shao, Hu Tian, Qiong Yuan, Xiaoming Wang, Guodong | 2008 | Journal of Southeast University(English Edition)2008，24，S1： | 2 |

| 19 | Microcoring and dendrometer-detected intra-annual wood formation of Populus euphratica in the Ejina Oasis,northwestern China显示文摘Seasonal stem radial growth and wood formation of trees have become research hotspots because of their significance for dendroclimatological and dendroecological studies. However, until recently, these studies concentrated on coniferous tree species in high-altitude and high-latitude regions, while detailed information on arid-zone riparian forests is scarce. The main focus of this study is to monitor the intra-annual dynamics of radial growth and tree ring formation in a deciduous species, Populus euphratica. In 2013, we combined the dendrometer and microcoring methods to study this species in the riparian forest of the Ejina Oasis, in arid northwestern China. Vessel enlargement began in early May, and the maximum rate of cell production occurred in early June. The cell division then ceased from early to mid-July. The dendrometer method failed to reliably detect the date of growth initiation and cessation, but succeeded to detect the time of maximum growth rate just like the microcoring method did. We found that weekly stem radial increment data described xylem growth more accurately than daily datasets. Based on correlation analysis among climatic and hydrologic variables, and weekly stem radial increment, weekly ring width increase dataset, the depth to groundwater was the main factor that limited tree ring growth. From a practical perspective, such studies of intra-annual wood formation can provide empirical guidance for seasonal water allocations within a river basin. | XiaoMei Peng ShengChun Xiao GuoDong Cheng QuanYan Tian HongLang Xiao | 2017 | Research in Cold and Arid Regions2017，9，1： | 1 |
| 20 | Recent Advances on Confining Noble Metal Nanoparticles Inside Metal-Organic Frameworks for Hydrogenation Reactions显示文摘Hydrogenation reaction is one of the pillars of the chemical industry for the synthesis of drugs and fine chemicals.To achieve high catalytic performance,it is still highly desirable for constructing novel supported metal catalysts.Different from conventional supports like metal oxides,zeolites and carbon materials,metal-organic frameworks(MOFs)as the emerging porous materials have exhibited great potential to host metal nanoparticles(NPs)for achieving hydrogenation reactions with high catalytic efficiency,due to their unique porous structures.Recently,many progresses have been made,and thus,it is necessary to summarize the recent progresses on confining metal NPs inside MOFs for hydrogenation reactions.In this review,we first introduced the general synthesis methods for confining noble metal NPs inside MOFs.Then,the applications of noble metal NPs/MOFs catalysts in hydrogenation reactions were summarized,and the synergistic catalytic performances among noble metal NPs,metal nodes,functional groups,and pore channels in MOFs were illustrated.Subsequently,the hydrogen spillover effect involved in the hydrogenation reactions was discussed.Finally,we provide an outlook on the future research directions and challenges of confining noble metal NPs inside MOFs for hydrogenation reactions. | LIN Tian WANG Haowu CUI Chengqian LIU Wei LI Guodong | 2022 | Chemical Research in Chinese Universities2022，38，6： | 1 |
