| 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 |
| 2 | An intracellular toxic protein (Xin) isolated from Xenorhabdus nematophilus strain BJ显示文摘An intracellular toxic protein, designated Xin and with remarkable inhibitory effect on growth of Helicoverpa armigera, was isolated from X. Nematophilus strain BJ by ion exchange chromatography and hydrophobic interaction chromatography. After placing neonates on the artificial diet containing Xin at concentration of 0 or 3.48μg/g for 7 days, the average weight of insects was 23.50mg and 0.55mg, respectively. The activity of Xin was lost by heating, freeze-drying, digestion with proteases or urea. The Xin molecular weight, over kD, was determined by gel filtration on Superose 12, and there were six component proteins analyzed by SDS-PAGE. The results show that Xin is a high molecular protein complex inhibiting growth of insect pest. | PAN Yinghong , JIAN Heng , ZHANG Jie , LIU Zheng, CHEN Zhongyi , YANG Xiufen, YANG Huaiwen and HUANG Dafang( State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing 100094, China Institute of Biocontrol Research, Chinese Academy of Agricultural Sciences, Beijing 100081, China Institute of Biotechnology Research, Chinese Academy of Agricultural Sciences, Beijing 100081, China.) | 2002 | Progress in Natural Science:Materials International2002,12,4: | 9 |
| 3 | Characterization of ornidazole metabolites in human bile after intraveneous doses by ultraperformance liquid chromatography/quadrupole time-of-flight mass spectrometry显示文摘Ultraperformance liquid chromatography/quadrupole time-of-flight mass spectrometry(UPLC/Q-TOF MS)was used to characterize ornidazole metabolites in human bile after intravenous doses.A liquid chromatography tandem mass spectrometry(LC–MS/MS)assay was developed for the determination of the bile level of ornidazole.Bile samples,collected from four patients with T-tube drainage after biliary tract surgery,were prepared by protein precipitation with acetonitrile before analysis.A total of 12 metabolites,including 10 novel metabolites,were detected and characterized.The metabolites of ornidazole in human bile were the products of hydrochloride(HCl)elimination,oxidative dechlorination,hydroxylation,sulfation,diastereoisomeric glucuronation,and substitution of NO_(2) or Cl atom by cysteine or N-acetylcysteine,and oxidative dechlorination followed by further carboxylation.The bile levels of ornidazole at 12 h after multiple intravenous infusions were well above its minimal inhibitory concentration for common strains of anaerobic bacteria. | Jiangbo Du Pan Deng Xiaoyan Chen Haidong Wang Tiangeng You Dafang Zhong | 2012 | Acta Pharmaceutica Sinica B2012,2,2: | 5 |
| 4 | Determination of ginsenoside compound K in human plasma by liquid chromatography–tandem mass spectrometry of lithium adducts显示文摘Ginsenoside compound K(GCK), the main metabolite of protopanaxadiol constituents of Panax ginseng, easily produces alkali metal adduct ions during mass spectrometry particularly with lithium. Accordingly, we have developed a rapid and sensitive liquid chromatography–tandem mass spectrometric method for analysis of GCK in human plasma based on formation of a lithium adduct. The analyte and paclitaxel(internal standard) were extracted from 50 m L human plasma using methyl tertbutyl ether. Chromatographic separation was performed on a Phenomenex Gemini C18 column(50 mm 2.0 mm; 5 μm) using stepwise gradient elution with acetonitrile–water and 0.2 mmol/L lithium carbonate at a flow rate of 0.5 m L/min. Detection was performed in the positive ion mode using multiple reaction monitoring of the transitions at m/z 629-449 for the GCK-lithium adduct and m/z 860-292 for the adduct of paclitaxel. The assay was linear in the concentration range 1.00–1000 ng/m L(r^2>40.9988)with intra- and inter-day precision of ±8.4% and accuracy in the range of 4.8% to 6.5%. Recovery,stability and matrix effects were all satisfactory. The method was successfully applied to a pharmacokinetic study involving administration of a single GCK 50 mg tablet to healthy Chinese volunteers. | Yunhui Chen Youming Lu Yong Yang Xiaoyan Chen Liang Zhu Dafang Zhong | 2015 | Acta Pharmaceutica Sinica B2015,5,5: | 3 |

| 14 | Land Use Change and Driving Forces in Guangzhou City during 1996- 2012显示文摘Based on the statistical data of land use change,from the perspective of sustainable use,we use literature inquiry,statistical analysis,GIS spatial analysis and dynamic degree model of land use,to analyze the land use change characteristics,land use amount and spatial distribution characteristics in Guangzhou City during 1996- 2012,and further elaborate the driving forces of land use change to get the basic law of land use change in Guangzhou City. The results show that the construction land was rapidly expanded,causing a significant reduction in arable land( from 129286 ha in 1996 to 84567 ha in 2012); in construction land,the land for residential,industrial and mining use and transportation land dramatically increased,and the single dynamic degree of transportation land was close to 7. 1%. In comparison with other developed cities,it is found that economic factors and policy factors are important factors affecting land use change in Guangzhou City,and the growth rate of economic density of land was high in Tianhe District and Yuexiu District. From the perspective of sustainable use,the future land use in Guangzhou City needs to better coordinate the relationship between various types of land,between socio-economic development and coordinated land use development,between environmental protection and land development and utilization. Through a series of land consolidation activities,it is necessary to strengthen the protection of farmland,improve the intensive and economical use of construction land,improve the ecological environment,and coordinate development of urban and rural areas,to ultimately achieve sustainable land use in Guangzhou City. | Yiying YAO Dafang WU Yanyan LIU Yihua LIU Qixian CHEN Haolong CHEN Jiaxin WU Jialiang ZHONG | 2015 | Asian Agricultural Research2015,7,9: | 1 |
