| 1 | Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased. | NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng | 2012 | Chinese Science Bulletin2012,57,22: | 51 |

| 4 | The first all-season sample set for mapping global land cover with Landsat-8 data显示文摘We report the world's first all-season training and validation sample sets for global land cover classification with Landsat-8 data.Prior to this,such samples were only available at a single date primarily from the growing season.It is unknown how much limitation such a single-date sample has to mapping global land cover in other seasons of the year.To answer this question,we selected available Landsat-8 images from four seasons and collected training and validation samples from them.We compared the performances of training samples in different seasons using Random Forest algorithm.We found that the use of training samples from any individual season would result in the best overall classification accuracy when validated by samples in the same season.The global overall accuracy from combined best seasonal results was 67.2% when classifying the 11 Level-1 classes in the Finer Resolution Observation and Monitoring of Global Land Cover(FROM-GLC) classification system.The use of training samples from all seasons(named all-season training sample set hereafter) produced an overall accuracy of 67.0%.We also tested classification within 10° latitude 60° longitude zones using all-season training subsample within each zone and obtained an overall accuracy of 70.2%.This indicates that properly grouped subsamples in space can help improve classification accuracies.All the results in this study seem to suggest that it is possible to use an all-season training sample set to reach global optimality with universal applicability in classifying images acquired at any time of a year for global land cover mapping. | Congcong Li Peng Gong Jie Wang Zhiliang Zhu Gregory S.

| 5 | Ozone sensitivity analysis with the MM5-CMAQ modeling system for Shanghai显示文摘Ozone has become one of the most important air pollution issues around the world. This article applied both O 3 /(NOy-NOx) and H 2 O 2 /HNO 3 indicators to analyze the ozone sensitivity in urban and rural areas of Shanghai, with implementation of the MM5-CMAQ modeling system in July, 2007. The meteorological parameters were obtained by using the MM5 model. A regional emission inventory with spatial and temporal allocation based on the statistical data has been developed to provide input emission data to the MM5-CMAQ modeling system. Results showed that the ozone concentrations in Shanghai show clear regional differences. The ozone concentration in rural areas was much higher than that in the urban area. Two indicators showed that ozone was more sensitive to VOCs in urban areas, while it tended to be NOx sensitive in rural areas of Shanghai. | Li Li Changhong Chen Cheng Huang Haiying Huang Gangfeng Zhang Yangjun Wang Minghua Chen Hongli Wang Yiran Chen D.

| 8 | Evaluation of Two Momentum Control Variable Schemes and Their Impact on the Variational Assimilation of Radar Wind Data:Case Study of a Squall Line显示文摘Different choices of control variables in variational assimilation can bring about different influences on the analyzed atmospheric state.Based on the WRF model's three-dimensional variational assimilation system,this study compares the behavior of two momentum control variable options—streamfunction velocity potential(ψ–χ) and horizontal wind components(U–V)—in radar wind data assimilation for a squall line case that occurred in Jiangsu Province on 24 August 2014.The wind increment from the single observation test shows that the ψ–χ control variable scheme produces negative increments in the neighborhood around the observation point because streamfunction and velocity potential preserve integrals of velocity.On the contrary,the U–V control variable scheme objectively reflects the information of the observation itself.Furthermore,radial velocity data from 17 Doppler radars in eastern China are assimilated.As compared to the impact of conventional observation,the assimilation of radar radial velocity based on the U–V control variable scheme significantly improves the mesoscale dynamic field in the initial condition.The enhanced low-level jet stream,water vapor convergence and low-level wind shear result in better squall line forecasting.However,the ψ–χ control variable scheme generates a discontinuous wind field and unrealistic convergence/divergence in the analyzed field,which lead to a degraded precipitation forecast. | Xin LI Mingjian ZENG Yuan WANG Wenlan WANG Haiying WU Haixia MEI | 2016 | Advances in Atmospheric Sciences2016,33,10: | 10 |

| 10 | Progress and perspectives of quantitative structure-activity relationships used for ecological risk assessment of toxic organic compounds显示文摘Structure-activity relationship (SAR) and quantitative structure-activity relationship (QSAR), collec- tively referred to as (Q)SARs, play an important role in ecological risk assessment (ERA) of organic chemicals. (Q)SARs can fill the data gap for physical-chemical, environmental behavioral and ecotoxicological parameters of organic compounds; they can decrease experimental expenses and reduce the extent of experimental testing (especially animal testing); they can also be used to assess the uncertainty of the experimental data. With the development for several decades, (Q)SARs in envi- ronmental sciences show three features: application orientation, multidisciplinary integration, and in- telligence. Progress of (Q)SAR technology for ERA of toxic organic compounds, including endpoint selection and mathematic methods for establishing simple, transparent, easily interpretable and portable (Q)SAR models, is reviewed. The recent development on defining application domains and diagnosing outliers is summarized. Model characterization with respect to goodness-of-fit, stability and predictive power is specially presented. The purpose of the review is to promote the development of (Q)SARs orientated to ERA of organic chemicals. | CHEN JingWen LI XueHua YU HaiYing | 2008 | Science China Chemistry2008,51,7: | 9 |
| 11 | Influences of water treatment agents on oil-water interfacial properties of oilfield produced water显示文摘The emulsion stability of oilfield produced water is related to the oil-water interfacial film strength and the zeta potential of the oil droplets. We investigated the effects of water treatment agents (corrosion inhibitor SL-2, scale inhibitor HEDP, germicide 1227, and flocculant polyaluminium chloride PAC) on the stability of oilfield produced water. The influence of these treatment agents on oil-water interfacial properties and the mechanism of these agents acting on the oilfield produced water were studied by measuring the interfacial shear viscosity, interfacial tension and zeta electric potential. The results indicated that the scale inhibitor HEDP could increase the oil-water interfacial film strength, and it could also increase the absolute value of the zeta potential of oil droplets. HEDP played an important role in the stability of the emulsion. Polyaluminum chloride (PAC) reduced the stability of the emulsion by considerably decreasing the absolute value of the zeta potential of oil droplets. Corrosion inhibitor SL-2 and germicide 1227 could decrease the oil-water interfacial tension, whereas they had little influence on oil-water interfacial shear viscosity and oil-water interfacial electricity properties. | Guo Jixiang Cao Jingjing Li Mingyuan Xia Haiying | 2013 | Petroleum Science2013,10,3: | 9 |
| 12 | Overexpression of the Watermelon Ethylene Response Factor ClERF069 in Transgenic Tomato Resulted in Delayed Fruit Ripening显示文摘Watermelon fruit undergoes distinct development stages with dramatic changes during fruit ripening.To date,the molecular mechanics of watermelon ripening remain unclear.Genetic and transcriptome evidences suggested that the ethylene response factor(ERF)gene ClERF069 may be an important candidate factor affecting watermelon fruit ripening.To dissect the roles of ClERF069 in fruit ripening,structure and phylogenetic analysis were performed using the amplified full-length sequence.Normal-ripening watermelon 97103,non-ripening watermelon PI296341-FR and the RIL population were used to analyze ClERF069 expression dynamics and the correlation with fruit ripening indexs.The results indicated that ClERF069 belongs to ERF family group VI and show high homology(83%identity)to melon ERF069-like protein.ClERF069 expression in watermelon flesh was negatively correlated with fruit lycopene content and sugar content during fruit ripening progress.Further transgenic evidences indicated that overexpression of 35S:ClERF069 in tomato noticeably delayed the ripening process up to 5.2 days.Lycopene,β-carotenoid accumulation patterns were altered and ethylene production patterns in transgenic fruits was significantly delayed during fruit ripening.Taken together,watermelon ethylene response factor ClERF069 was concluded to be a negative regulator of fruit ripening. | Ming Zhou Shaogui Guo Shouwei Tian Jie Zhang Yi Ren Guoyi Gong Changbao Li Haiying Zhang Yong Xu | 2020 | Horticultural Plant Journal2020,6,4: | 9 |

| 14 | Inhibition of miR-144-3p exacerbates non-small cell lung cancer progression by targeting CEP55显示文摘Increasing evidence has indicated that microRNA dysregulation is closely related to the occurrence and development of cancers.Herein,we investigated the relationship between miR-144-3p&CEP55 expression.We then evaluated the association between miR-144-3p&CEP55 expression,&proliferation,invasion&apoptosis of non-small cell lung cancer[NSCLC]cells.Real-time quantitative PCR results revealed that CEP55 was over-expressed whereas miR-144-3p was underexpressed in NSCLC tissues.CCK-8 assay,wound healing assay,&flow cytometry further revealed that overexpression of miR-144-3p significantly inhibited proliferation&migration,but promoted apoptosis of A549 cells.Conversely,inhibition of miR-144-3p promoted proliferation. | Ming Li Yannan Liu Xinglin Jiang Yuanxin Hang Haiying Wang Hang Liu Zhuo Chen Yubo Xiao | 2021 | Acta Biochimica et Biophysica Sinica2021,53,10: | 7 |
| 15 | Toxic effects of 1-methyl-3-octylimidazolium bromide on the wheat seedlings显示文摘The toxic effects of 1-methyl-3-octylimidazolium bromide ([C8 mim]Br) on wheat seedlings were evaluated.Wheat seedlings were cultivated in aqueous solution with [C8 mim]Br at different concentrations (0,1,2,4,6,8 mg/L).The contents of photosynthetic pigment and proline,peroxidation of membrane lipid,and activities of antioxidation enzymes (superoxide dismutase,catalase,peroxidase and ascorbate peroxidase) in leaves were measured on day 7 after treatment with [C8 mim]Br.The results showed that [C8 mim]Br significantly decreased the contents of photosynthetic pigments,activities of antioxidant enzymes in the wheat leaves and in dry weight of seedlings,while increased the proline content and membrane lipid peroxidation.The results suggested that [C8 mim]Br can inhibit photosynthesis and lead to oxidative stress to wheat seedlings. | Ping Liu Yifeng Ding Haiying Liu Liping Sun Xiaoyu Li Jianji Wang | 2010 | Journal of Environmental Sciences2010,22,12: | 6 |
| 16 | Acute high-altitude hypoxic brain injury Identification of ten differential proteins显示文摘Hypobaric hypoxia can cause severe brain damage and mitochondrial dysfunction,and is involved in hypoxic brain injury.However,little is currently known about the mechanisms responsible for mitochondrial dysfunction in hypobaric hypoxic brain damage.In this study,a rat model of hypobaric hypoxic brain injury was established to investigate the molecular mechanisms associated with mitochondrial dysfunction.As revealed by two-dimensional electrophoresis analysis,16,21,and36 differential protein spots in cerebral mitochondria were observed at 6,12,and 24 hours post-hypobaric hypoxia,respectively.Furthermore,ten protein spots selected from each hypobaric hypoxia subgroup were similarly regulated and were identified by mass spectrometry.These detected proteins included dihydropyrimidinase-related protein 2,creatine kinase B-type,isovaleryl-CoA dehydrogenase,elongation factor Ts,ATP synthase beta-subunit,3-mercaptopyruvate sulfurtransferase,electron transfer flavoprotein alpha-subunit,Chain A of 2-enoyl-CoA hydratase,NADH dehydrogenase iron-sulfur protein 8 and tropomyosin beta chain.These ten proteins are all involved in the electron transport chain and the function of ATP synthase.Our findings indicate that hypobaric hypoxia can induce the differential expression of several cerebral mitochondrial proteins,which are involved in the regulation of mitochondrial energy production. | Jianyu Li Yuting Qi Hui Liu Ying Cui Li Zhang Haiying Gong Yaxiao Li Lingzhi Li Yongliang Zhang | 2013 | Neural Regeneration Research2013,8,31: | 6 |

| 18 | Production of aryl oxygen-containing compounds by catalytic pyrolysis of bagasse lignin over LaTi0.2Fe0.8O3 prepared by different methods显示文摘To realize the resource and high-value utilization,a new approach,named bagasse lignin(BL) used to produce aryl oxygen-containing compounds by catalytic pyrolysis over perovskite,was proposed,LaTi0.2Fe0.8O3(LTF) samples prepared by the sol-gel method(SG) and the solid-state reaction method(SS)were characterized.The catalytic action on BL pyrolysis was performed by the test of TG-DTG and the evaluation of the fixed bed micro-reactor,the components and contents of the products were determined.The results show that LTF samples have cubic perovskite phase,LTF prepared by SG(LTF-SG) is porous with larger specific surface area than LTF prepared by SS(LTF-SS).During the pyrolysis of BL,the addition of LTF lowers the pyrolysis temperature and the activation energy,the contents of CO2 and CO in gaseous products reduce by 4.6%-8.0% and 30.7%-34.3%,respectively,the total content of aryl oxygencontaining compounds(including phenolics,guaiacols,syringols and phenylates) in liquid products increases from 62 wt% to more than 72 wt%,and LTF-SG shows better catalytic performance.LTF samples have nice phase and catalytic stabilities for BL pyrolysis after five successive redox cycles. | Haiying Wang Hongjing Han Enhao Sun Yanan Zhang Jinxin Li Yanguang Chen Hua Song Hongzhi Zhao Yue Kang | 2020 | Journal of Rare Earths2020,38,1: | 5 |
| 19 | A β-glucosidase-producing M-2 strain: Isolation from cow dung and fermentation parameter optimization for flaxseed cake显示文摘Flaxseed cake contains cyanogenic glucosides, which can be metabolized into hydrocyanic acid in an animal's body, leading to asphyxia poisoning in cells. Beta-glucosidase is highly efficient in degrading cyanogenic glucosides. The Cattle may have b-glucosidase-producing strains in the intestinal tract after eating small amounts of flaxseed cake for a long time. This study aimed to isolate of a strain from cow dung that produces b-glucosidase with high activity and can significantly reduce the amount of cyanogenic glucosides. We used cow dung as the microflora source and an esculin agar as the selective medium. After screening with 0.05% esculin and 0.01% ferric citrate, we isolated 5 strains producing high amounts of b-glucosidase. In vitro flaxseed cake fermentation was fermented by these 5 strains, in which the strain M-2 exerted the best effect(P < 0.05). The strain M-2 was identified as Lichtheimia ramosa and used as the fermentation strain to optimize the fermentation parameters by a single factor analysis and orthogonal experimental design. The optimum condition was as follows: inoculum size3%, water content 60%, time 144 h, and temperature 32℃. Under this condition, the removal rate of cyanogenic glucosides reached 89%, and crude protein increment reached 44%. These results provided a theoretical basis for the removal of cyanogenic glucosides in flaxseed and the comprehensive utilization of flaxseed cake. | Chenhui Li Junshu Wei Yaping Jing Baoxia Teng Pingrong Yang Xinjun Chen Haiying Huang Tang Zhao Tuanjie Che Chunjiang Zhang | 2019 | Animal Nutrition2019,,1: | 5 |
| 20 | Identifying changes in the wheat kernel proteome under heat stress using iTRAQ显示文摘Wheat(Triticum aestivum L.) is one of the three major global food crops. Hightemperature stress can affect its yield and quality. Studies of the effect of hightemperature stress on wheat kernel development are important because they can reveal the stability of wheat quality and lead to the genetic improvement of wheat quality traits. In this study, the isobaric tags for relative and absolute quantitation(iTRAQ)method was adopted to analyze changes in the protein expression profile of wheat cultivars under high temperature stress. The protein content of wheat grain increased under heat stress, while the SDS-sedimentation value and starch content decreased.Grain filling was deficient under high temperature stress, which reduced thousandkernel weight but did not affect wheat kernel length. The 207 differentially expressed proteins identified in Gaocheng 8901 under heat stress were associated with energy metabolism, growth and development, and stress response. Gene Ontology enrichment analysis showed that the annotated proteins that were differentially expressed in Gaocheng 8901 under heat stress were involved mainly in stimulus response, abiotic stress response, stress response, and plasma membrane. A set of 78 differentially expressed proteins were assigned to 83 KEGG signaling/metabolic pathways. KEGG pathway enrichment analysis showed that this set of proteins was significantly enriched in members of 51 pathways, and the proteins participated mainly in protein synthesis in the endoplasmic reticulum, starch and sucrose metabolism, and reaction on ribosomes. Five differentially expressed proteins were involved in protein–protein interaction networks that may greatly influence the yield and quality of wheat grain. In wheat, high-temperature stress leads to a variety of effects on protein expression and may ultimately cause changes in yield and quality. | Yufeng Zhang Hongyao Lou Dandan Guo Ruiqi Zhang Meng Su Zhenghong Hou Haiying Zhou Rongqi Liang Chaojie Xie Mingshan You Baoyun Li | 2018 | The Crop Journal2018,6,6: | 5 |
