| 1 | Effects of glutamine on intestinal permeability and bacterial translocation in TPN-rats with endotoxemia显示文摘AIM: To evaluate the protective effect and mechanism ofglutamine on the intestinal barrier function in totalparenteral nutrition (TPN) rats with trauma or endotoxemia.
METHODS: To perform prospective, randomized andcontrolled animal experimentation of rats with surgicaltrauma, TPN and endotoxemia, thirty-four male, adultSprague Dawley rats were divided into four groups: control group (n=8), TPN group (n=9), trauma and endotoxemia group (LPS, n=8) and trauma plus endotoxemia supplemented with glutamine in TPN solution group (Gin.group, n=9). All groups except the control group were given TPN solutions in 7-day experimental period. For Gin group, 1 000 mg/kg/d of glutamine was added to TPN solution during day 1-6. On the 7th day all the animals were gavaged with lactulose (66 mg) and mannitol (50 mg)in 2 mi of normal saline. Then 24 h urine with preservative was collected and kept at -20 ℃. On day 8, under intraperitoneal anesthesia using 100 mg/kg ketamin, the intestine, liver, mesenteric lymph nodes and blood were taken for examination.
RESULTS: The body weight of LPS group decreased most among the four groups. The structure of small intestinal mucosa in TPN group, LPS group and Gln group showed impairments of different degrees, and the damage of small intestinal mucosa in Gln group was remarkably alleviated.The concentrations of interleukins in small intestine mucosa were lower (for IL-4 and IL-6) or the lowest (IL-10) in Gln group. The IgA level in the blood plasma and the mucosa of Gln group was the highest among all of the groups. The urine lactulose/mannitol test showed that the intestinal permeability in LPS group was lower than that in TPN group (P<0.001), but there was no difference between LPS group and Gln group. The rate of bacterial translocation in Gln group was lower than that in LPS group (P<0.02).
CONCLUSION: Prophylactic treatment with glutamine could minimize the increments of intestinal permeability and bacterial translocation caused by trauma and endotoxemia in rats treated with TPN. | Lian-An Ding Jie-Show Li Clinical College of Nanjing University Medical School,305 East Zhongshan Road,Nanjing 210002 Jiangsu Province,China | 2003 | World Journal of Gastroenterology2003，9，6： | 89 |
| 2 | Some evidence of drying trend over northern China from 1951 to 2004显示文摘The surface wetness index, Palmer drought sererity index and the retrieval of soil moisture over China were calculated using monthly precipitation and monthly mean surface air temperature. Based on the contrast analysis of the variation of the above three indices and precipitation, the dry/wet spatio-temporal pattern of northern China in the last 54 years was revealed, and the evidence of drying trend over northern China was analyzed, especially. The results show the following four facts: (1) The drying trend is the main characteristic of the eastern part of Northwest China and the central part of North China since the 1980s and it was enhanced in the last 15 years mainly due to the precipitation decrease and the temperature increase; (2) During the last 54 years, there was only one dry/wet shift at the interdecadal scale occurring in the eastern part of Northwest China and the central part of North China in the late 1970s, which was related to 1977/1978 global abrupt change, whereas there were three shifts in Northeast China, one was in the mid 1990s and the other two were in 1965 and 1983, respectively; (3) Unlike the variation trend of other subregions of northern China, the western part of Northwest China is currently located in a relatively wetting period, which is weak-ened due to the temperature increase; (4) The extreme drought frequency is obviously increasing in the eastern part of Northwest China, the central part of North China and Northeast China since the 1980s, which is closely related to the precipitation decrease and temperature increase in these subregions. | MA Zhuguo1,2 & FU Congbin1,2 1.

| 3 | TRANSPORT OF THE SUSPENDED SEDIMENT IN THE CHANGJIANG ESTUARY显示文摘The Changjiang River is characterized by the enormous volume of runoff and the great amount of sediment load with remarkable seasonal variation. The annual runoff sometimes is respondent to the amount of sediment load, and sometimes not. The amount of monthly sediment load after the month of the maximum runoff is larger than those before the month. The sediment concentration and net quantity of sediment transport in the vicinity of the river mouth varies greatly in time between the ebb and flood, spring and neap, and dry seasons and flood seasons. The three bifurcations also have differences in concentration and net quantity in space. Even in the same bifurcation they have differences in and out of the sand bar. At present, the North Channel is the main passage for water and sediment load emptying into the sea from the Changjiang River. More than 50 percent of the sediments from the river basin are deposited nearby the South Branch entrance and the main depositional area is situated in subaqueous delta off the South Channel. Between 122°30’E and 123°E is an important boundary for eastward sediment dispersion from which the suspended sediment are dispersed towards the east by south. | SHEN Huanting Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China LI Jiufa Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHU Huifang Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China HAN Mingbao Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHOU Fugen Department of Marine Geology, Tongji Univcrsity, Shanghai, China | 1992 | International Journal of Sediment Research1992，7，3： | 37 |

| 6 | Geospatial-temporal analysis of land-use changes in the Yellow River Delta during the last 40 years显示文摘Comprehensive study on land-use change of spatial pattern and temporal process is the key component in land use/land cover changes (LUCC) study nowadays. According to the theories and methods of Geo-information Tupu (Carto-methodology in Geo-information, CMGI) for geospatial and temporal analysis and integration models of spatial pattern and temporal processes in GIS, the paper puts forward Tupu methodology of land-use change and names the basic synthetic unit of spatial-temporal information Tupu unit. Tupu unit is the synthetic unit for geospatial-temporal analysis, which is synthesized by “space·attribute·process”features and composed of relatively homogeneous geographic unit and temporal unit. Based on the spatial features of 4 stages of land-use change in 1956, 1984, 1991, and 1996, a series of Tupu on land-use change in the Yellow River Delta (YRD) are created and studied in the paper, which includes 3 temporal units of spatial-temporal Tupu, process Tupu of land-use changes during the last 40 years, and reconstructions of a series of “arisen”Tupu, “arisen”process Tupu and pattern Tupu on land-use changes in the last 40 years by remapping tables of a reclassifying system. There are 3 methods of Tupu analysis on land-use change that are used to disclose change processes of land-use spatial conversion in YRD, such as spatial query and statistics, order of Tupu units by area and land-use conversion matrixes. In order to reveal the spatial pattern of land-use change processes, we analyze spatial-temporal changes of each Tupu above in various temporal units and spatial difference of pattern Tupu in the last 40 years by dynamic Tupu units. Tupu analysis on regional land-use is a promising trial on the comprehensive research of “spatial pattern of dynamic process”and “temporal process of spatial pattern”in LUCC research. The geo-information Tupu methodology would be a powerful and efficient tool on integrated studies of spatial pattern and temporal process in geoscience. | YE Qinghua1,3,4,LIU Gaohuan2,TIAN Guoliang1,CHEN Shenliang3,HUANG Chong2,CHEN Shupeng1,2,LIU Qingshen2,CHANG Jun2 & SHI Yanan2 1.State Key Laboratory of Remote Sensing Science,Institute of Remote Sensing Applications(IRSA),Chinese Academy of Science(CAS),Beijing 100101,China 2.Institute of Geographic Sciences and Natural Resources Research,CAS,Beijing 100101,China 3.State Key Laboratory of Estuarine and Coastal Research,East China Normal University,Shanghai 200062,China 4.Institute of Tibetan Plateau Research(ITPR),CAS,Beijing 100085,China Correspondence should be addressed to Ye Qinghua(email: yeqh@itpcas.ac.cn) | 2004 | Science China Earth Sciences2004，47，11： | 22 |
| 7 | The biomass and aboveground net primary productivity of Schima superba-Castanopsis carlesii forests in east China显示文摘The biomass and productivity of Schima superba-Castanopsis carlesii forests in Tiantong,Zhejiang Province,were determined using overlapping quadrants and stem analyses.The total community biomass was(225.3±30.1) t hm-2,of which the aboveground parts accounted for 72.0% and the underground parts accounted for 28.0%.About 87.2% of biomass existed in the tree layer.The resprouting biomass was small,of which over 95.0% occurred in the shrub layer.The productivity of the aboveground parts of the community was(386.8±98.9) g m-2a-1,in which more than 96.0% was present at the tree level.The trunk's contribution to productivity was the greatest,while that of leaves was the smallest.In China,the community biomass of subtropical evergreen broadleaved forests differs significantly with the age of the forest.The community biomass of the 52-year-old S.superba-C.carlesii forests in this study was lower than the average biomass of subtropical evergreen broadleaved forests in China,and was lower than the biomass of other subtropical evergreen broadleaved forests elsewhere in the world.Moreover,its productivity was lower than the model estimate,indicating that without disturbance,this community has great developmental potential in terms of community biomass and productivity. | YANG TongHui1,2,SONG Kun1,DA LiangJun1*,LI XiuPeng3 & WU JianPing1 1School of Resources and Environment Science,East China Normal University,Shanghai 200062,China 2Ningbo Academy of Agricultural Science,Ningbo 315040,China 3Ningbo Technology Extension Center for Forestry and Specialty Forest Products,Ningbo 315012,China | 2010 | Science China(Life Sciences)2010，53，7： | 23 |
| 8 | TRAF-mediated regulation of immune and inflammatory responses显示文摘The tumor necrosis factor (TNF) receptor-associated factor (TRAF) family consists of six mammalian members,and is shown to participate in signal transduction of a large number of receptor families including TNF receptor family (TNFR) and Toll-like receptors-interleukin-1 receptors (TLR-IL-1R) family.Upon receptor activation,TRAFs are directly or indirectly recruited to the intracellular domains of these receptors.They subsequently engage other signaling proteins to activate inhibitor of κB kinase (IKK) complex,TRAF family member-associated NF-κB activator (TANK)-binding kinase 1 (TBK1) and inducible I κB kinase (IKK-i) (also known as IKKε),ultimately leading to activation of transcription factors such as NF-κB and interferon-regulatory factor (IRF) to induce immune and inflammatory responses. | WANG YaYa1,ZHANG Peng2,LIU YingFang2 & CHENG GenHong1 1 Department of Microbiology,Immunology & Molecular Genetics,University of California Los Angeles,609 Charles E.Young Drive East,Los Angeles,California 90095,USA 2 National Laboratory of Biomacromolecules,Institute of Biophysics,Chinese Academy of Sciences,Beijing 100101,China | 2010 | Science China(Life Sciences)2010，53，2： | 19 |
| 9 | Deep seismic reflection profiling revealing the complex crustal structure of the Tongling ore district显示文摘The deep seismic profiling across the Tongling ore district reveals a complex crustal structure. Strong contrasting dipping layered reflections (4—11 s, TWT),which dominate the lower crust of the northern part of the profile, are interpreted as the underplating of the basalt related to extensional tectonism. In the south of the profile, the Yangtze craton is characterized by strong reflections in the middle crust, showing a distinct two-layer crustal structure. Over the region of the Tongling uplift, there appear the complex arc shape reflections, suggesting folded, faulted and intruded structures, and the transparent zone below them reveals the existence of batholith. The south dipping strong reflections between the upper crust and lower crust (4—7 s, TWT) suggest a detachment between them. The detachment provided space for the magma intrusion, and caused the formation of the batholith. The Yangtze craton has a clear Moho re-flection, while the Tongling uplift has a weak Moho, whereas below the reflective lower crust in the northern part of the profile, there are sub-Moho reflections. The abrupt variation of the Moho characteristics within a short distance indicates the complexity of magmatic activity. | L5 Qingtian1, HOU Zengqian1, ZHAO Jinhua1, SHI Danian1, WU Xuanzhi1, CHANG Yinfo1, PEI Rongfu1,HUANG Dongding2 & KUANG Chaoyang2 1.

| 10 | Development of ancestors' cultivation revealed in phytolith assemblages from Guangfulin relics显示文摘Shanghai Museum has got great achievements in re-excavating Guangfulin relics. It is the first time that the cultural remains of Wangyoufang type is found above the Liangzhu cultural remains which comes from East Henan Province, providing previous materials for researching cul-ture evolution around Taihu Lake. Samples were taken from the immature soil layer and cultural layers of Guangfulin relics for phytolith analysis. According to the systemic re-search for the archaeological remains and phytolith fossil, the phytoliths in Guangfulin relics can be divided into four zones. The development of rice agriculture and living condi-tion of Guangfulin ancestors was discussed based on the ex-isting rice fan-shaped phytolith, rice shell phytolith, diatom fossil and archaeology evidence in the same layer. The Guangfulin relics has gradually developed since a high sea level 5000 years ago, and the broad rice agriculture has si-multaneously developed. The newly re-excavated relics pro-vides valuable materials for the research of ancestors and ancient culture in Shanghai. | ZHANG Yulan1,2, ZHANG Minbin1 & SONG Jian3 1.

| 11 | Impact on the Yangtze (Changjiang) Estuary from its drainage basin: Sediment load and discharge显示文摘This paper focuses on the sediment transport and freshwater discharging from upper Yangtze drainage basin downstream, primarily on the basis of multiyear hy-drological data collected from three major hydrological gauge stations (Yichang, Hankou and Datong). Data indicate highest sediment load in Yichang (5.6×108 t/a), lowest in Hankou (5.1×108t) and second highest in Datong (5.4×108 t). This fluctuations are identical with what has been observed from the annual flood season. About one thirds of the sediment load are trapped in the middle Yangtze River course, where meandering river pattern prevails; rest of them are directly transported to the river mouth area via lower Yangtze River channel, where the river is typically confined by the exposed base rock and almost none is being trapped, instead, minor being drained to the mainstream from the local tributaries. To recognize this sediment delivery and river flow media is vital, because it can highlight morphologic/topographic correlation between the | CHEN Zhongyuan & ZHAO YiwenState Key Laboratory for Estuarine and Coastal Research, East China Normal University, Shanghai 200062, China Department of Geography, East China Normal University, Shanghai 200062, China | 2001 | Chinese Science Bulletin2001，46，S1： | 16 |
| 12 | The Bedload Movement in the Changjiang Estuary显示文摘- Sandwaves in the Changjiang estuary were measured with a shallow sediment profiler and an echosounder from 1978 to 1988. The data, together with grain size and bedform of sediment indicates that the bedload movement by rolling and saltation is of great significance to sediment transport and is the principal factor responsible for sandwave and sandbody development in the estuary. The sandwaves were found well-developed, which is related to the tidal range and the velocity of ebb current. However, the further growth is restricted by strong flood current prevailing in the estuary. Because of the significant bedload, the sandbodies shift obviously and frequently, and sometimes the exchange of position occurs between the sandbodies and tidal channels. As a result, ships are regularly forced to change their navigation course. | Li Jiufa, Shi Weirong, Shen Huanting Xu Haigen and Doeke Eisma Associate Professor, Institute of Estuarine & Coastal Research (1ECR), East China Normal University, Shanghai200062 Professor, IECR, East China Normal University, Shanghai 200062 Professor, Netherlands Institute for Sea Research, P.

| 13 | Denitrification in Chongming east tidal flat sediment, Yangtze estuary, China显示文摘From July 2003 to July 2004, samples were collected on Chongming Island east tidal flat every two months. The research showed that the nitrous oxide (N2O) production rate was very low in the water, Chongming east tidal flat (CM) sediment was the N2O source of the water. Sediment N2O natural production rate was between -0.08 and 1.74 μmolN·m-2·h-1. N2O natural production rate was higher in the summer. The difference of the N2O natural production rate in the different tidal flats, the correlation between the N2O natural production rate and the denitrification rate, and those with the temperature and DO indicate that middle tidal flat sediment denitrification was the main process of the N2O production, while in the low tidal flat sediment, the production of the N2O came from several processes of the nitrogen cycling. Tidal flat sediment denitrification reaction was stronger in summer and winter but relatively lower in the late autumn and early spring. Seasonal change of the sediment denitrification rate was wide, from 1.12 to 33.34 μmolN·m-2·h-1. Temperature, DO and the coactions of them had the prominent effect on the tidal flat sediment denitrification. | WANG Dongqi1,2, CHEN Zhenlou1,3, XU Shiyuan1,2, HU Lingzhen1 & WANG Jun1,2 1.

| 14 | Three-year changes of surface albedo of degraded grassland and cropland surfaces in a semiarid area显示文摘Diurnal, seasonal and interannual variations of surface albedo of degraded grassland and cropland surfaces at a semiarid area of Tognyu have been investigated based on the continuous three years observational data from 2003 to 2005. The changes of surface albedo with solar elevation angle and soil moisture have been discussed also. It has been found that surface albedo has almost the same diurnal and seasonal variations on degraded grassland and cropland surfaces in the semiarid area, while sur- face albedo is large in winter and small in summer. The diurnal variation of the surface albedo has re- lationship with the weather condition. The diurnal cycle of the surface albedo likes the 'U' shape curve in sunny day, while it is low-high after the rain, and high-low after the snow. The surface albedo has large variation in cloudy day, while it has no any variation in overcast day. The large difference of the surface albedo can be 0.04 in winter between two land surfaces, because the snow has large effects on the surface albedo in winter. The rainfall is an important factor in summer on the surface albedo, while the difference of the surface albedo is 0.01 only between two land surfaces. The differences of the surface albedo can also be 0.04 in autumn due to vegetation growing. The seasonal-average surface albeo from 2003―2005 is 0.25, 0.22, 0.24, 0.32 respectively in spring, summer, autumn and winter on the degraded grassland surface,while it is 0.25, 0.21, 0.22, 0.33 respectively in spring, summer, autumn and winter on the cropland surface. The surface albedo becomes smaller with the increase of solar elevation angle. When the solar elevation angle is greater than 40°, the surface albedo changes very little and tends to be a constant. The surface albedo has negative exponent functions with soil moisture in the growing season. | LIU HuiZhi1↑, TU Gang2,3 & DONG WenJie4 1 State Key Laboratory of Atmospheric Boundary Layer Physics and Atmospheric Chemistry, Institute of Atmospheric Physics, Chi- nese Academy of Sciences, Beijing 100029, China 2 Laboratory of Research for Middle-High Latitude Circulation System and East Asia Monsoon, China Meteorological Administration, Changchun 130062, China 3 Institute of Meteorological Science of Jilin Province, Changchun 130062, China 4 National Climate Center, Beijing 100081, China | 2008 | Chinese Science Bulletin2008，53，8： | 14 |
| 15 | Modeling the climate effects of different subregional uplifts within the Himalaya-Tibetan Plateau on Asian summer monsoon evolution显示文摘Considering the different uplifting time of different subregions of the Himalaya-Tibetan Plateau(TP),a series of numerical simulations have been conducted with the Community Atmosphere Model(CAM4) developed at the National Center for Atmospheric Research to explore the effects of the phased tectonic uplift of the Himalaya-TP on the evolution of Asian summer monsoons.The results show that the uplifts of the Himalaya and northern TP significantly affect the evolutions of South Asian summer monsoon and northern East Asian summer monsoon respectively.That is,the tectonic uplift of the Himalaya intensifies the South Asian summer monsoon circulation and increases the precipitation in South Asia,whereas the uplift of the northern TP intensifies the northern East Asian summer monsoon circulation and increases the precipitation in northern East Asia.Compared with previous simulations,current comparative analyses of modeling results for different subregional uplifts within the Himalaya-TP help deepen our understanding of the evolutionary history of Asian monsoons. | ZHANG Ran 1,JIANG DaBang 1,2,3,LIU XiaoDong 4 & TIAN ZhiPing 2,5 1 Climate Change Research Center,Chinese Academy of Sciences,Beijing 100029,China 2 Nansen-Zhu International Research Centre,Institute of Atmospheric Physics,Chinese Academy of Sciences,Beijing 100029,China 3 Key Laboratory of Regional Climate-Environment Research for Temperate East Asia,Chinese Academy of Sciences,Beijing 100029,China 4 State Key Laboratory of Loess and Quaternary Geology,Institute of Earth Environment,Chinese Academy of Sciences,Xi’an 710075,China 5 Graduate University of Chinese Academy of Sciences,Beijing 100049,China | 2012 | Chinese Science Bulletin2012，57，35： | 14 |

| 17 | Transumbilical endoscopic surgery:History,present situation and perspectives显示文摘Transumbilical endoscopic surgery or laparo-endoscopic single site(LESS)surgery has become an exciting area of surgical development as innovation continues to move in the 21st century to minimally invasive surgery.The history,present situation and perspectives are reviewed and the nomenclature of this technique is discussed in this article.The range of this technique has been applied in almost all abdominal diseases,surgeries for morbid obesity,hernia and so on,in recent years.It is estimated that 50%-80%of traditional laparoscopic surgery could be performed transumbilically in the next five years according to the LESSCAR consensus.Although the concept of transumbilical laparoscopic surgery is gaining traction rapidly and the instruments have been improved greatly, we should not advocate for slightly improved cosmetic value over safety.Multicenter,randomized and clinical trials are necessary to further elucidate the safety and efficiency of this new technique.Research that examines the efficacy of the new instruments on the market may be helpful to simplify the confusing landscape of new and novel products designed for this purpose. | Jiang-Fan Zhu,Department of Minimally Invasive Surgery,East Hospital of Tongji University,Shanghai 200120,China | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，6： | 13 |
| 18 | Effect of Protein Kinase C on Proliferation and Apoptosis of T Lymphocytes in Idiopathic Thrombocytopenic Purpura Children显示文摘It is well-documented that T lymphocyte proliferation and apoptosis are abnormal in idiopathic thrombocytopenic purpura (ITP) children. However, the underlying regulation mechanisms especially in terms of signal transduction remain unknown. In this paper, we reported the changes of protein kinase C (PKC) activity in peripheral blood T lymphocytes and the effect of PKC on T lymphocyte proliferation and apoptosis. We demonstrated that in ITP children, the activator (PMA) and inhibitor (H-7) of PKC affected on T lymphocyte proliferation and apoptosis dramatically, but they altered little in healthy children. PKC activity was significantly enhanced in ITP children together with an increased expression of FasL on CD3+ T, CD4+ T and CD8+T cells, resulting in a positive correlation between PKC activity and the expression of FasL on T cells. While the PKC activity and the platelet count were negatively correlated. Taken together, our findings suggest that the PKC activation may enhance T lymphocytes activity, suppress T cell apoptosis and be involve in thrombocytes damage as a mechanism related to immune pathogenesis of ITP. | Changlin Wu~(1,2) Fang Liu~1 Xuemin Zhou~1 Zhengwei Cheng~1 Xiaomeng Yang~1 Hong Xiao~1 Qun Chen~1 Kangrong Cai~1 ~1Department of Microbiology and Immunology,Guangdong Medical College,Zhanjiang,Guangdong,524023,China ~2Corresponding to:Dr.Changlin Wu,Department of Microbiology and Immunology,Guangdong Medical College,2 Wen-Ming East Road,Zhanjiang,Guangdong,524023,China. | 2005 | Cellular & Molecular Immunology2005，2，3： | 12 |
