| 1 | Effects of thymol and carvacrol supplementation on intestinal integrity and immune responses of broiler chickens challenged with Clostridium perfringens显示文摘Background: Necrotic enteritis caused by Clostridium perfringens infection leads to serious economic losses in the global poultry production. In the present study, we investigated the protective effects of essential oils(EO, which contained 25 % thymol and 25 % carvacrol as active components) supplementation on growth performance, gut lesions, intestinal morphology, and immune responses of the broiler chickens infected with C. perfringens. A total of448 1-day-old male broiler chicks were allocated into eight treatment groups following a 4 × 2 factorial arrangement with four dietary EO dosages(0, 60, 120, or 240 mg/kg) and two infection status(with or without C. perfringens challenge from d 14 to 20).Results: The challenge did not impair the growth performance of birds, but induced gut lesions and increased crypt depth in the ileum(P ≤ 0.05). It also down-regulated the claudin-1 and occludin m RNA expression(P ≤ 0.05),up-regulated the m RNA expression of interleukin-1β(P ≤ 0.05), tended to increase the toll-like receptor(TLR)2 m RNA expression(P < 0.10) in the ileum, and enhanced the mucosal secretory Ig A production(P ≤ 0.05). In the challenged birds, dietary EO supplementation linearly alleviated the gut lesions and improved the ratio of vil us height to crypt depth(P ≤ 0.05), and the supplementation of 120 and 240 mg/kg EO increased the serum antibody titers against Newcastle disease virus(P ≤ 0.05). Regardless of challenge, the EO supplementation showed a tendency to linearly elevate the feed conversion efficiency between 14 and 28 d of age as well as the occludin m RNA expression(P < 0.10), and linearly inhibited the m RNA expression of TLR2 and tumor necrotic factor-α in the ileum(P ≤ 0.05).Conclusions: The dietary supplementation of EO could alleviate the intestinal injury by improving intestinal integrity and modulating immune responses in the C. perfringens-challenged broiler chickens. | Encun Du Weiwei Wang Liping Gan Zhui Li Shuangshuang Guo Yuming Guo | 2016 | Journal of Animal Science and Biotechnology2016，7，4： | 43 |

| 5 | In vitro antibacterial activity of thymol and carvacrol and their effects on broiler chickens challenged with Clostridium perfringens显示文摘Background:In the post-antibiotic era,essential oils(EO) are promising alternatives to growth-promoting antibiotics.The aim of the present study was to investigate the antibacterial activities of an EO product and its components thymol and carvacrol in vitro,and the efficacy of EO to control Clostridium perfringens challenge in broiler chickens.Results:The in vitro minimum inhibitory concentration assay showed strong antibacterial activity of the EO product,thymol,and carvacrol against pathogenic Escherichia coli,C.perfringens,and Salmonella strains,and weak activity towards beneficial Lactobacillus strains.Besides,an additive effect was observed between thymol and carvacrol.The in vivo study was carried out with 448 male broiler chicks following a 4 × 2 factorial arrangement to test the effects of EO supplementation(0,60,120,or 240 mg/kg EO in wheat-based diet),pathogen challenge(with or without oral gavage of C perfringens from day 14 to day 20) and their interactions.Each treatment consisted of eight replicate pens(seven birds/pen).The challenge led to macroscopic gut lesions,and resulted in a significant increase in ileal populations of C.perfringens and Escherichia subgroup(P< 0.05) on day 21.Dietary EO supplementation did not influence C perfringens numbers,but linearly alleviated intestinal lesions on day 21 and 28(P=0.010 and 0.036,respectively),and decreased Escherichia populations in ileum with increased EO dosages(P=0.027 and 0.071 for day 21 and 28,respectively).For caecum,EO quadratically influenced Lactobacillus populations on day 21(p=0.002),and linearly decreased the numbers of total bacteria and Escherichia on day 28(P=0.026 and 0.060,respectively).Mean thymol and carvacrol concentrations in the small intestine were 0.21 and 0.20 μg/g in intestinal digesta(wet weight),respectively,for birds fed 60 mg/kg EO,and 0.80 and 0.71 μg/g,respectively,for birds fed 240 mg/kg EO.Conclusions:These results indicated that dietary EO supplementation could affect intestinal microbiota and alleviate intestinal lesions in broilers,which may contribute in controlling C.perfringens infection in broiler chickens. | Encun Du Liping Gan Zhui Li Weiwei Wang Dan Liu Yuming Guo | 2016 | Journal of Animal Science and Biotechnology2016，7，1： | 14 |
| 6 | Incorporating temporal variability to improve geostatistical analysis of satellite-observed CO_2 in China显示文摘Observations of atmospheric carbon dioxide (CO2 ) from satellites offer new data sources to understand global carbon cycling. The correlation structure of satellite-observed CO2 can be analyzed and modeled by geostatistical methods, and CO2 values at unsampled locations can be predicted with a correlation model. Conventional geostatistical analysis only investigates the spatial correlation of CO2 , and does not consider temporal variation in the satellite-observed CO2 data. In this paper, a spatiotemporal geostatistical method that incorporates temporal variability is implemented and assessed for analyzing the spatiotemporal correlation structure and prediction of monthly CO2 in China. The spatiotemporal correlation is estimated and modeled by a product-sum variogram model with a global nugget component. The variogram result indicates a significant degree of temporal correlation within satellite-observed CO2 data sets in China. Prediction of monthly CO2 using the spatiotemporal variogram model and spacetime kriging procedure is implemented. The prediction is compared with a spatial-only geostatistical prediction approach using a cross-validation technique. The spatiotemporal approach gives better results, with higher correlation coefficient (r2 ), and less mean absolute prediction error and root mean square error. Moreover, the monthly mapping result generated from the spatiotemporal approach has less prediction uncertainty and more detailed spatial variation of CO2 than those from the spatial-only approach. | ZENG ZhaoCheng LEI LiPing GUO LiJie ZHANG Li ZHANG Bing | 2013 | Chinese Science Bulletin2013，58，16： | 12 |

| 8 | Land-surface processes and summer-cloud-precipitation characteristics in the Tibetan Plateau and their effects on downstream weather:a review and perspective显示文摘Correct understanding of the land-surface processes and cloud-precipitation processes in the Tibetan Plateau(TP)is an important prerequisite for the study and forecast of the downstream activities of weather systems and one of the key points for understanding the global atmospheric movement.In order to show the achievements that have been made,this paper reviews the progress on the observations for the atmospheric boundary layer,land-surface heat fluxes,cloud-precipitation distributions and vertical structures by using ground-and space-based multiplatform,multisensor instruments and the effect of the cloud system in the TP on the downstream weather.The results show that the form drag related to the topography,land-atmosphere momentum and scalar fluxes is an important part of the parameterization process.The sensible heat flux decreased especially in the central and northern TP caused by the decrease in wind speeds and the differences in the ground-air temperatures.Observations show that the cloud and precipitation over the TP have a strong diurnal variation.Studies also show the compressed-air column in the troposphere by the higher-altitude terrain of the TP makes particles inside clouds vary at a shorter distance in the vertical direction than those in the non-plateau area so that precipitation intensity over the TP is usually small with short duration,and the vertical structure of the convective precipitation over the TP is obviously different from that in other regions.In addition,the influence of the TP on severe weather downstream is preliminarily understood from the mechanism.It is necessary to use model simulations and observation techniques to reveal the difference between cloud precipitation in the TP and non-plateau areas in order to understand the cloud microphysical parameters over the TP and the processes of the land boundary layer affecting cloud,precipitation and weather in the downstream regions. | Yunfei Fu Yaoming Ma Lei Zhong Yuanjian Yang Xueliang Guo Chenghai Wang Xiaofeng Xu Kun Yang Xiangde Xu Liping Liu Guangzhou Fan Yueqing Li Donghai Wang | 2020 | National Science Review2020，7，3： | 10 |

| 11 | Synergetic effects of aqueous extracts of Fuzi(Radix Aconiti Lateralis Preparata) and Tubeimu(Rhizoma Bolbostemmatis) on MDA-MB-231 and SKBR3 cells显示文摘OBJECTIVE: To test the synergistic effects of the aqueous extract of Tubeimu(Rhizoma Bolbostemmatis) and Fuzi(Radix Aconiti Lateralis Preparata) on MDA-MB-231 and SKBR3 breast cancer cells.METHODS: A combined index was created for the effects of Tubeimu(Rhizoma Bolbostemmatis) and Fuzi(Radix Aconiti Lateralis Preparata) extracts. Cell proliferation was performed by trypan blue exclusion and 3-(4,5-dimethylthiazol-2-yl)-5-(3- carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium(MTS) assays. Flow cytometry was used to assess cell cycle distribution and apoptosis. Cell migration was determined by wound-healing and transwell assays. Confocal microscopy was used to detect E-cadherin and actin filaments.RESULTS: The aqueous extract from Tubeimu(Rhizoma Bolbostemmatis) and Fuzi(Radix Aconiti Lateralis Preparata) exerted synergetic effects on the growth of MDA-MB-231 cells and G1 phase arrest.When exposed to extracts at concentrations of 62.5∶62.5 and 62.5∶31.3 μg/m L, the combination index was 0.83 and 0.74, respectively. Interestingly, 62.5∶31.3 μg/m L of combined drugs enhanced the inhibitory effect of Tubeimu(Rhizoma Bolbostemmatis)on the migration of SKBR3 cells and reduced the stimulative effect of Fuzi(Radix Aconiti Lateralis Preparata)(P < 0.01), in which cells showed an increased expression of E-cadherin and reorganization of actin filaments(P < 0.001). 62.5∶62.5 μg/m L extract also synergistically induced apoptosis of MDA-MB-231 cells(P < 0.05 and P < 0.001). Acting as the main active ingredients in the extract, tubeimoside I and acetylbenzoylaconine at 10∶10 μg/m L and 5∶2.5 μg/m L also produced inhibitory effects on the proliferation and migration of cells(P <0.01).CONCLUSION: Tubeimu(Rhizoma Bolbostemmatis)and Fuzi(Radix Aconiti Lateralis Preparata) extracts had synergic effects on MDA-MB-231 and SKBR3 cells. | Chen Dan Cao Rui He Jinghua Guo Yuan Wang Liping Ji Wei Wu Xiongzhi | 2016 | Journal of Traditional Chinese Medicine2016，36，1： | 8 |
| 12 | Simultaneous regulation of cations and anions in an electrolyte for high-capacity, high-stability aqueous zinc–vanadium batteries显示文摘Safe,inexpensive aqueous zinc-ion batteries(AZIBs)are regarded as promising energy storage devices.However,they still face issues,including dissolution and collapse of the cathode as well as H_(2)evolution and the growth of Zn dendrites on the Zn anode.Herein,we simultaneously regulate the cations and anions in the electrolyte for high-capacity,high-stability aqueous zinc–vanadium(Zn–V)batteries based on a bimetallic cation-doped Na_(0.33)K_(0.1)V_(2)O_(5)·nH_(2)O cathode.We demonstrate that Na^(+) cations suppress cathode dissolution and restrain Zn dendrite growth on the anode via an electrostatic shield effect.We also illustrate that ClO_(4)^(-) anions participate in energy storage at the cathode and are reduced to Cl^(-),generating a protective layer on the Zn anode surface and providing a stable interface to decrease Zn dendrites and H_(2)evolution during long-term cycling.When Na^(+) and ClO_(4)^(-) are introduced into an aqueous ZnSO_(4) electrolyte,a Zn/Zn symmetric cell shows durable and reversible Zn stripping/plating for 1500 h at a current density of 1 mA cm^(-2) and with an area capacity of 1 mAh cm^(-2).Zn/Na_(0.33)K_(0.1)V_(2)O_(5)·nH_(2)O full batteries exhibit a high capacity of 600 mAh g^(-1)at 0.1 A g^(-1) and long-term cycling performance for 5000 cycles,with a capacity of 200 mAh g^(-1) at 20 Ag^(-1). | Ziqing Wang Miao Zhou Liping Qin Minghui Chen Zixian Chen Shan Guo Liangbing Wang Guozhao Fang Shuquan Liang | 2022 | eScience2022，2，2： | 8 |
| 13 | Tumor-expressed B7-H3 mediates the inhibition of antitumor T-cell functions in ovarian cancer insensitive to PD-1 blockade therapy显示文摘Although PD-L1/PD-1 blockade therapy has been approved to treat many types of cancers,the majority of patients with solid tumors do not respond well,but the underlying reason remains unclear.Here,we studied ovarian cancer(OvCa),a tumor type generally resistant to current immunotherapies,to investigate PD-1-independent immunosuppression.We found that PD-L1 was not highly expressed in the tumor microenvironment(TME)of human OvCa.Instead,B7-H3,another checkpoint molecule,was highly expressed by both tumor cells and tumor-infiltrating antigen-presenting cells(APCs),which correlated with T-cell exhaustion in patients.Using ID8 OvCa mouse models,we found that B7-H3 expressed on tumor cells,but not host cells,had a dominant role in suppressing antitumor immunity.Therapeutically,B7-H3 blockade,but not PD-1 blockade,prolonged the survival of ID8 tumorbearing mice.Collectively,our results demonstrate that tumor-expressed B7-H3 inhibits the function of CD8^(+)T cells and suggest that B7-H3 may be a target in patients who are not responsive to PD-L1/PD-1 inhibition,particularly OvCa patients. | Dongli Cai Jiaming Li Dingfeng Liu Shanjuan Hong Qin Qiao Qinli Sun Pingping Li Nanan Lyu Tiantian Sun Shan Xie Li Guo Ling Ni Liping Jin Chen Dong | 2020 | Cellular & Molecular Immunology2020，17，3： | 8 |
| 14 | Pollen-inferred Holocene vegetation and climate histories in Taro Co,southwestern Tibetan Plateau显示文摘A 310-cm-long sediment core,covering the last10,200 years,was collected from Taro Co on the southwestern Tibetan Plateau and analyzed for pollen,grain size and total inorganic carbon content.The pollen data showed that vegetation changed from alpine steppe to alpine meadow during 10,200–8,900 cal a BP,to alpine steppe dominated by Artemisia during 8,900–7,400 cal a BP,to alpine meadow during 7,400–3,300 cal a BP and to alpine steppe after 3,300 cal a BP.Correspondingly,the pollen,grain size and total inorganic carbon content results revealed climatic change in this area over four stages.The initial stage was from 10,200 to 8,900 cal a BP,during which the climate changed from cold-dry to warm-humid.The second stage(8,900–7,400 cal a BP)was characterized by a warm and dry climate.However,at approximately7,400 cal a BP,the climate began to become cold and humid,which continued until 3,300 cal a BP.The last stage,from 3,300 cal a BP to present,was characterized as cold and increasingly arid.Climatic events of the early and mid-late Holocene showed that the area was significantly affected by the westerlies.However,the mid-Holocene climate in Taro Co was controlled by the Indian monsoon.The mid-late Holocene depositional environment record of Taro Co was very important to further elaborate the degree of influence by the westerlies or Indian monsoon. | Qingfeng Ma Liping Zhu Xinmiao L Yun Guo Jianting Ju Junbo Wang Yong Wang Lingyu Tang | 2014 | Chinese Science Bulletin2014，59，31： | 7 |

| 16 | Variation of soil enzyme activity and microbial biomass in poplar plantations of different genotypes and stem spacings显示文摘To improve the productivity of poplar plantations, a field experiment of split-plot design with four tree spacings and three poplar clones was established, and four soil enzyme activities and microbial biomass were monitored in the trial.Soil enzyme activities, in most cases,were significantly higher in topsoil(0–10 cm) than in lower horizons(10–20 cm).Soil cellulase, catalase and protease activities during the growing season were higher than during the non-growing season, while invertase activity followed the opposite trend.Soil invertase, cellulase and catalase activities varied by poplar clone but soil protease activity did not.Cellulase and protease activities in the plantation at 5×5 m spacing were significantly higher than in the other spacings.The highest catalase activity was recorded at 6×6 m spacing.At the same planting density, invertase activity was greater in square spacings than in rectangular spacings.Soil microbial biomass was also significantly affected by seedling spacing and poplar clone.The mean soil MBC was significantly lower in topsoil than in the lower horizon, while MBN showed the opposite pattern.Significantly positive correlations were observed among soil cellulase, protease and catalase activities(p<0.01), whereas soil invertase activity was negatively and significantly correlated with cellulase, protease and catalase activities(p<0.01).Soil microbial biomass and enzyme activities were not correlated except for a significantly negative correlation between soil MBC and catalase activities.Variations in soil enzyme activity and microbial biomass in different poplar plantations suggest that genotype and planting spacing should be considered when modeling soil nutrient dynamics and managing for long-term site productivity. | Ye Li Liping Zhang Shengzuo Fang Ye Tian Jiao Guo | 2018 | Journal of Forestry Research2018，29，4： | 5 |

| 18 | Physical modeling of spent-nuclearfuel container显示文摘A new physical simulation model was developed to simulate the casting process of the ductile iron heavy section spent-nuclear-fuel container.In this physical simulation model,a heating unit with DR24 Fe-Cr-Al heating wires was used to compensate the heat loss across the non-natural surfaces of the sample,and a precise and reliable casting temperature controlling/monitoring system was employed to ensure the thermal behavior of the simulated casting to be similar to the actual casting.Also,a mould system was designed,in which changeable mould materials can be used for both the outside and inside moulds for different applications.The casting test was carried out with the designed mould and the cooling curves of central and edge points at different isothermal planes of the casting were obtained.Results show that for most isothermal planes,the temperature control system can keep the temperature differences within 6 ℃ between the edge points and the corresponding center points,indicating that this new physical simulation model has high simulation accuracy,and the mould developed can be used for optimization of casting parameters of spent-nuclear-fuel container,such as composition of ductile iron,the pouring temperature,the selection of mould material and design of cooling system.In addition,to maintain the spheroidalization of the ductile iron,the force-chilling should be used for the current physical simulation to ensure the solidification of casting in less than 2 h. | Wang Liping Guo Erjun Jiang Wenyong Xue Muyu Liu Dongrong Ren Shanzhi | 2012 | China Foundry2012，9，4： | 5 |
| 19 | Dynamic analysis of the Wenchuan Earthquake disaster and reconstruction with 3-year remote sensing data显示文摘Earth observation is an effective technique that plays an important role in earthquake damage reduction and reconstruction.This paper introduces the results of dynamic analysis on monitoring and assessing heavily impacted areas affected by the Wenchuan Earthquake using remote sensing data acquired in the past 3 years from 2008 to 2010.Immediately after the disaster on 12 May 2008,the Chinese Academy of Sciences launched a project entitled‘Wenchuan Earthquake Disasters Monitoring and Assessment Using Remote Sensing Technology.’More than 400 images from 17 satellites and 20.2TB airborne remote sensing data were acquired to facilitate quick monitoring and evaluation of severely damaged areas in 14 counties.Results of the image analyses were forwarded on a timely basis to assist with consultative service and decisionmaking support.In subsequent years,in order to monitor the process of environmental restoration and reconstruction,airborne optical remote sensing images covering most of the severely damaged areas were again acquired in May 2009 and April 2010.These images were analyzed and compared along with images from 2008.Results were useful in support of further work on environmental protection and reconstruction in earthquake-damaged areas.Three typical areas were selected for illustrative purposes including Tangjiashan Barrier Lake,Beichuan County,and counties of Yingxiu and the new Beichuan.These results well demonstrate the importance and effectiveness of the utility of earth observation for disaster mitigation and reconstruction. | Huadong Guo Liangyun Liu Liping Lei Yanhong Wu Liwei Li Bing Zhang Zhengli Zuo Zhen Li | 2010 | International Journal of Digital Earth2010，3，4： | 5 |
| 20 | Genetic analysis of yield and fiber quality traits in upland cotton(Gossypium hirsutum L.) cultivated in different ecological regions of China显示文摘Background:Cotton is an important fiber crop worldwide.The yield potential of current genotypes of cotton can be exploited through hybridization.However,to develop superior hybrids with high yield and fiber quality traits,information of genetic control of traits is prerequisite.Therefore,genetic analysis plays pivotal role in plant breeding.Results:In present study,North Carolina II mating design was used to cross 5 female parents with 6 male parents to produce 30 intraspecific F1cotton hybrids.All plant materials were tested in three different ecological regions of China during the year of 2016-2017.Additive-dominance-environment(ADE)genetic model was used to estimate the genetic effects and genotypic and phenotypic correlation of yield and fiber quality traits.Results showed that yield traits except lint percentage were mainly controlled by genetic and environment interaction effects,whereas lint percentage and fiber quality traits were determined by main genetic effects.Moreover,dominant and additiveen vironine nt in teraction effects had more influence on yield traits,whereas additive and domi nance-e nviron ment interaction effects were found to be predominant for fiber traits.Broad-sense and its interaction heritability were significant for all yield and most of fiber quality traits.Narrow-sense and its interaction heritability were non-significant for boll number and seed cotton yield.Correlation analysis indicated that seed cotton yield had significant positive correlation with other yield attributes and non-significant with fiber quality traits.All fiber quality traits had signiflcant positive correlation with each other except micronaire.Conclusions:Results of current study provide important information about genetic control of yield and fiber quality traits.Further,this study identified that parental lines,e.g.,SJ48-1,ZB-1,851-2,and DT-8 can be utilized to improve yield and fiber quality traits in cotton. | SHAHZAD Kashif LI Xue QI Tingxiang GUO Liping TANG Huini ZHANG Xuexian WANG Hailin ZHANG Meng ZHANG Bingbing QIAO Xiuqin XING Chaozhu WU Jianyong | 2019 | Journal of Cotton Research2019，2，2： | 5 |
