1A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s).QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China 2003Chinese Science Bulletin2003,48,10:121
2Palaeozoic tectonic evolution of the Tianshan belt,NW China显示文摘The Chinese Tianshan belt is a major part of the southern Central Asian Orogenic Belt,extending westward to Kyrgyzstan and Kazakhstan.Its Paleozoic tectonic evolution,crucial for understanding the amalgamation of Central Asia,comprises two stages of subduction-collision.The first collisional stage built the Eo-Tianshan Mountains,before a Visean unconformity,in which all structures are verging north.It implied a southward subduction of the Central Tianshan Ocean beneath the Tarim active margin,that induced the Ordovician-Early Devonian Central Tianshan arc,to the south of which the South Tianshan back-arc basin opened.During the Late Devonian,the closure of this ocean led to a collision between Central Tianshan arc and the Kazakhstan-Yili-North Tianshan Block,and subsequently closure of the South Tianhan back-arc basin,producing two suture zones,namely the Central Tianshan and South Tianshan suture zones where ophiolitic mélanges and HP metamorphic rocks were emplaced northward.The second stage included the Late Devonian-Carboniferous southward subduction of North Tianshan Ocean beneath the Eo-Tianshan active margin,underlined by the Yili-North Tianshan arc,leading to the collision between the Kazakhstan-Yili-NTS plate and an inferred Junggar Block at Late Carboniferous-Early Permian time.The North Tianshan Suture Zone underlines likely the last oceanic closure of Central Asia Orogenic Belt;all the oceanic domains were consumed before the Middle Permian.The amalgamated units were affected by a Permian major wrenching,dextral in the Tianshan.The correlation with the Kazakh and Kyrgyz Tianshan is clarified.The Kyrgyz South Tianshan is equivalent to the whole part of Chinese Tianshan(CTS and STS) located to the south of Narat Fault and Main Tianshan Shear Zone;the so-called Middle Tianshan thins out toward the east.The South Tianshan Suture of Kyrgyzstan correlates with the Central Tianshan Suture of Chinese Tianshan.The evolution of this southern domain remains similar from east(Gangou area) to west until the Talas-Ferghana Fault,which reflects the convergence history between the Kazakhstan and Tarim blocks.Jacques CHARVET SHU LiangShu Sebastien LAURENT-CHARVET WANG Bo Michel FAURE Dominique CLUZEL CHEN Yan Koen De JONG 2011Science China Earth Sciences2011,54,2:57

6Effects of dietary Clostridium butyricum supplementation on growth performance,intestinal development,and immune response of weaned piglets challenged with lipopolysaccharide显示文摘Background: Weanling pigs, with immature immune system and physiological function, usually experience postweaning diarrhea. This study determined the effects of dietary Clostridium butyricum supplementation on growth performance, diarrhea, and immunity of weaned pigs challenged with lipopolysaccharide(LPS).Methods: In Experiment(Exp.) 1,144 weaned piglets were weaned at 21 d and randomly assigned to six groups,with six replicates per group and four pigs per replicate, receiving a control diet(CON) or diet supplemented with antibiotics(AB) or C. butyricum(CB)(0.1%, 0.2%, 0.4%, or 0.8%), respectively. All diets in Exp. 1 were a highly digestible basal diet, with 3,000 mg/kg zinc oxide supplied in the first 2 wk only. In Exp. 2, 180 piglets were weaned at 21 d and randomly assigned to five groups, with six replicates per group and six pigs per replicate, receiving CON, AB, or CB(0.2%, 0.4%, or 0.6%) diets. The digestibility of diets was lower than those in Exp. 1, and did not include zinc oxide. At 36 d of Exp. 2, 12 piglets were selected from each of the CON and 0.4% CB groups, six piglets were intraperitoneally injected with LPS(50 μg/kg body weight) and the other six piglets with normal saline;animals were killed at 4 h after injection to collect blood, intestine, and digesta samples for biochemical analysis.Results: In Exp. 1, CB and AB diets had no effect on growth performance of piglets. In Exp. 2, 0.4% CB decreased feed-gain ratio(P < 0.1), diarrhea score(P < 0.05), and increased duodenal, jejunal, and ileal villus height and jejunal villus height/crypt depth(P < 0.05). The 0.4% CB decreased the plasma tumor necrosis factor(TNF) α(P < 0.05) but increased ileal mucosa IL-10 and TLR2 mRNA expression(P < 0.05). Furthermore, 0.4% CB altered the microbial profile, with Bacillus and Ruminococcaceae UGG-003 at genus level and Lactobacillus casei and Parasutterella secunda at species level were higher than CON in colonic content(P < 0.05).Conclusions: Dietary C. butyricum supplementation had positive effects on growth of weaned piglets with less digestible diets. There was a tendency to reduce the feed-gain ratio, which could reduce feed costs in pig production. Moreover, C. butyricum decreased post-weaning diarrhea by improving the intestinal morphology,intestinal microflora profile, and immune function.Ling Chen Shuang Li Jie Zheng Wentao Li Xuemei Jiang Xilun Zhao Jian Li Lianqiang Che Yan Lin Shengyu Xu Bin Feng Zhengfeng Fang De Wu 2018Journal of Animal Science and Biotechnology2018,9,4:26
7Indoor Allergen Levels and Household Distributions in Nine Cities Across China显示文摘Objective Chinese allergic subjects have high levels of sensitization to house dust mite(HDM) and other indoor allergens. This study quantifies common indoor allergen levels in Chinese households. Methods Dust samples were collected from nine cities. Major allergens Der p 1 and Der f 1 from Dermatophagoides pteronyssinus and D. farinae, and specific antigens of Blomia tropicalis, Tyrophagus putrescentiae, Acarus siro, and cockroach species Blattella germanica and Periplaneta americana were measured by ELISA. Results HDM allergens were found in dust samples from bedding in 95% of the Chinese households. The median levels varied from <0.006 to 9.2 μg/g of dust, depending on the city. The percentages of households having HDM allergen levels associated with the risk of developing allergy sensitization and asthma were 65% and 25%, respectively. Specific antigens of the storage mite and cockroach were only found in samples from the southern and tropical regions of China. Levels of mite allergens were generally higher in samples from bedding compared to samples from the living room, even for storage mites, whereas levels of cockroach antigens were higher in the living room samples. Conclusion HDM allergens are present in bedding dust samples from most Chinese households. Cities in southern and central China have relatively high levels of HDM major allergens compared to cities in northern and western China. Antigens of storage mites and cockroaches are not as common as HDM allergens.ZHENG Yi Wu LAI Xu Xin ZHAO De Yu ZHANG Chun Qing CHEN Jian Jun ZHANG Luo WEI Qing Yu CHEN Shi LIU En Mei NORBACK Dan GJESING Birgitte ZHONG Nan Shan SPANGFORT D.Michael 2015Biomedical and Environmental Sciences2015,28,10:24
8A MULTISCALE SOIL LOSS EVALUATION INDEX显示文摘Exploring the relationships between land use and soil erosion at different scales is a fron-tier research field and a hot spot topic in contempo-rary physical geography. Based on the scale-pattern-process theory in landscape ecology and with consideration of such influential factors as land use, topography, soil and rainfall, this paper ap-plies the scale transition method to establishing a soil loss evaluation index at different scales and puts forward a research path and methodology for mul-tiscale soil loss evaluation indices. The multiscale soil loss evaluation index is applied to the evaluation of relationships between land use and soil erosion and the research of soil erosion evaluation at multiple scales. It provides a new method for optimizing the design of regional land use patterns and integrated multiscale research.FU Bojie ZHAO Wenwu CHEN Liding Lü Yihe WANG De 2006Chinese Science Bulletin2006,51,4:22

10Detection of hepatitis C virus NS5 protein and genome in Chinese carcinoma of the extrahepatic bile duct and its significance显示文摘AIM To investigate the hepatitis C virus(HCV)infection in the tissues of carcinoma ofextrahepatic bile duct and study theircorrelation.METHODS HCV NS5 protein and HCV RNA weredetected by labeled streptavidin biotin(LSAB)method and in situ reverse transcriptionpolymerase chain reaction(IS-RT-PCR)insections of 51 cases of carcinoma ofextrahepatic bile duct and 34 cases of controlgroup(without malignant biliary disease).RESULTS In 51 cases of carcinoma ofextrahepatic bile duct,HCV NS5 protein wasdetected in 14(27.5%),which was clearlystained in the cytoplasm of cancer cell but not inthe nucleus or cell membrane.HCV RNA wasdetected in 18(35.4%),which was located inthe nucleus of cancer cell in 12 cases and in thecytoplasm in 6 cases.HCV NS5 protein and RNAcoexistence was found in 2 cases.In 34 cases ofcontrol group,HCV RNA was detected in 2(5.9%).HCV NS5 protein and RNA positive cellswere found either scattered or in clusters.CONCLUSION The prevalence of hepatitis C viral infection in the tissues of carcinoma ofextrahepatic bile duct was significantly higherthan in control group(X^2=9.808,P=0.002).The findings suggest a correlation between HCVinfection and carcinoma of extrahepatic bileduct,which is different from the traditionalviewpoint.HCV infection might be involved inthe development of carcinoma of extrahepaticbile duct.Ming Yi Chen Zhi Qiang Huang Le Zhen Chen Ya Bing Gao Rui Yun Peng De Wen Wang 2000World Journal of Gastroenterology2000,6,6:19
11DNA and histone methylation in gastric carcinogenesis显示文摘Epigenetic alterations contribute significantly to the development and progression of gastric cancer,one of the leading causes of cancer death worldwide.Epigenetics refers to the number of modifications of the chromatin structure that affect gene expression without altering the primary sequence of DNA,and these changes lead to transcriptional activation or silencing of the gene.Over the years,the study of epigenetic processes has increased,and novel therapeutic approaches that target DNA methylation and histone modifications have emerged.A greater understanding of epigenetics and the therapeutic potential of manipulating these processes is necessary for gastric cancer treatment.Here,we review recent research on the effects of aberrant DNA and histone methylation on the onset and progression of gastric tumors and the development of compounds that target enzymes that regulate the epigenome.Danielle Queiroz Calcagno Carolina Oliveira Gigek Elizabeth Suchi Chen Rommel Rodriguez Burbano Marília de Arruda Cardoso Smith 2013World Journal of Gastroenterology2013,19,8:14
12Experimental investigation of railway train-induced vibrations of surrounding ground and a nearby multi-story building显示文摘In this paper, a field experiment was carried out to study train-induced environmental vibrations. During the field experiment, velocity responses were measured at different locations of a six-story masonry structure near the Beijing-Guangzhou Railway and along a small road adjacent to the building. The results show that the velocity response levels of the environmental ground and the building floors increase with train speed, and attenuate with the distance to the railway track. Heavier freight trains induce greater vibrations than lighter passenger trains. In the multi-story building, the lateral velocity levels increase monotonically with floor elevation, while the vertical ones increase with floor elevation in a fluctuating manner. The indoor floor vibrations are much lower than the outdoor ground vibrations. The lateral vibration of the building along the direction of weak structural stiffness is greater than along the direction with stronger stiffness. A larger room produces greater floor vibrations than the staircase at the same elevation, and the vibration at the center of a room is greater than at its corner. The vibrations of the building were compared with the Federal Transportation Railroad Administration (FTA) criteria for acceptable ground-borne vibrations expressed in terms of rms velocity levels in decibels. The results show that the train-induced building vibrations are serious, and some exceed the allowance given in relevant criterion.Xia He Chen Jianguo Wei Pengbo Xia Chaoyi G. De Roeck G.

13Increase of TNFα-stimulated Osteoarthritic Chondrocytes Apoptosis and Decrease of Matrix Metalloproteinases 9 by NF-κB Inhibition显示文摘Objective To investigate the in vitro effect of caffeic acid phenethyl ester(CAPE),a NF-κB inhibitor,on the apoptosis of osteoarthritic(OA)chondrocytes and on the regulation of the gelatinases matrix metalloproteinase 2(MMP-2)and matrix metalloproteinase 9(MMP-9).Methods Annexin V-FITC/propidium iodide(PI)labeling and western blotting were used to observe and determine the apoptosis in TNFα-stimulated primary cultured osteoarthritic chondrocytes.Also,gelatin zymography was applied to examine MMP-2 and MMP-9 activities in supernatants.Results It was confirmed by both flow cytometry and western blotting that chondrocytes from OA patients have an apoptotic background.Use of CAPE in combination with 10 ng/mL of TNFα for 24 h facilitated the apoptosis.MMP-9 in the supernatant could be autoactivated(from proMMP-9 to active MMP-9),and the physiologic calcium concentration(2.5 mmol/L)could delay the autoactivation of MMP-9.The activities of MMP-2 and MMP-9 in the fresh supernatant increased significantly in response to stimulation by 10 ng/mL of TNFα for 24 h.The stimulatory effect of TNFα just on proMMP-9 was counteracted significantly by CAPE.Conclusion NF-κB could prevent chondrocytes apoptosis though its activation was attributed to the increase of proMMP-9 activity induced by TNFα(a pro-apoptotic factor).Therefore,therapeutic NF-κB inhibitor was a 'double-edged swords' to the apoptosis of chondrocytes and the secretion of MMP-9.WANG Yan LI De Ling ZHANG Xin Bo DUAN Yuan Hui WU Zhi Hong HAO Dong Sheng CHEN Bao Sheng QIU Gui Xing 2013Biomedical and Environmental Sciences2013,26,4:13
14Impacted Lower Third Molar Fused with a Supernumerary Tooth—Diagnosis and Treatment Planning Using Cone-Beam Computed Tomography显示文摘This paper reported a case of fusion between an impacted third molar and a supernumerary tooth, in which a surgical intervention was carried out, with the objective of removing the dental elements. The panoramic radiography was complemented by the Donovan's radiographic technique; but because of the proximity of the dental element to the mandibular ramus, it was not possible to have a final fusion diagnosis. Hence, the Cone-Beam Computed Tomography―which provides precise threedimensional information―was used to determinate the fusion diagnosis and also to help in the surgical planning. In this case report we observed that the periapical, occlusal and panoramic were not able to show details which could only be examined through the cone-beam computed tomography.Osny Ferreira-Junior Luciana Dorigatti de .&.Aila Marcelo Bonifacio da Silva Sampieri Eduardo Dias- Ribeiro Wei-liang Chen Song Fan 2009International Journal of Oral Science2009,1,4:11

16Allergy-related Evidences in Relation to Serum IgE:Data from the China State Key Laboratory of Respiratory Disease,2008-2013显示文摘Objective To investigate the serum total IgE(tlgE) and specific IgE(slgE) to common allergens among allergic patients in Guangzhou,China.Methods 7 085 patients were examined for tlgE and slgE to 15 allergens,based on the protocols of reversed enzyme allergosorbent test and the sandwich enzyme-linked immunosorbent assay.Results 3 758(53.04%) patients tested positive for tlgE,and 4 640(65.49%) for slgE.Der pteronyssinus,Der farinae,eggs,and cow's milk were the most common allergens leading to higher positive rates of slgE responses.Several peaks of sensitization were:Der pteronyssinus,Der farinae,and Blomia tropicalis at age 10-12;cow's milk at age below 3;eggs at age 4-6.The mean level and positive rate of tlgE tended to increase in subjects sensitized to more allergens.Sensitization to Der pteronyssinus(OR,1.6;P<0.05),Der farinae(OR,1.5;P<0.05),Blomia tropicalis(OR,1.4;P<0.05),Blattella germanica(OR,1.5;P<0.05),cow's milk(OR,1.3;P<0.05),and soy beans(OR,2.0;P<0.05) were independently correlated with allergy-related conditions in preliminary diagnosis.Conclusion The major allergens in Guangzhou include Der pteronyssinus,Der farinae,cow's milk,and eggs.Sensitization to these allergens appears to be predictors of allergy-related disorder.SUN Bao Qing CHEN De Hui ZHENG Pei Yan HUANG Hui Min LUO Wen Ting ZENG Guang Qiao ZHANG Xiao Wen 2014Biomedical and Environmental Sciences2014,27,7:11
17The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
18Cidea controls lipid droplet fusion and lipid storage in brown and white adipose tissue显示文摘Excess lipid storage in adipose tissue results in the development of obesity and other metabolic disorders including diabetes,fatty liver and cardiovascular diseases.The lipid droplet(LD)is an important subcellular organelle responsible for lipid storage.We previously observed that Fsp27,a member of the CIDE family proteins,is localized to LD-contact sites and promotes atypical LD fusion and growth.Cidea,a close homolog of Fsp27,is expressed at high levels in brown adipose tissue.However,the exact role of Cidea in promoting LD fusion and lipid storage in adipose tissue remains unknown.Here,we expressed Cidea in Fsp27-knockdown adipocytes and observed that Cidea has similar activity to Fsp27 in promoting lipid storage and LD fusion and growth.Next,we generated Cidea and Fsp27 double-deficient mice and observed that these animals had drastically reduced adipose tissue mass and a strong lean phenotype.In addition,Cidea/Fsp27 double-deficient mice had improved insulin sensitivity and were intolerant to cold.Furthermore,we observed that the brown and white adipose tissues of Cidea/Fsp27double-deficient mice had significantly reduced lipid storage and contained smaller LDs compared to those of Cidea or Fsp27single deficient mice.Overall,these data reveal an important role of Cidea in controlling lipid droplet fusion,lipid storage in brown and white adipose tissue,and the development of obesity.WU LiZhen ZHOU LinKang CHEN Cheng GONG JingYi XU Li YE Jing LI De LI Peng 2014Science China(Life Sciences)2014,57,1:11
19Influence of high-fluorine environmental background on crops and human health in hot spring-type fluorosis-diseased areas显示文摘Drinking water-type fluorosis is the most harmful endemic disease in China with the largest number of sufferers. Although the implementation of the policy to alter water sources to lower fluoride level has effectively controlled the spread of this kind of endemic disease,its prevalence could not thoroughly be stopped because the high-fluoride environmental background in these endemically diseased areas could still do harm to human health through food chain. Therefore,it is necessary to conduct a more deep-going study on the drinking water-type fluoro-sis. To investigate the effect of high fluorine environmental background on crops and human health in the hot spring-type fluorosis-diseased areas,local water,paddy soil,rice,whole vegetables and soils around their roots were sampled for analysis. The results were compared with those of the control groups in fluorosis-free areas which are similar to the fluorosis-diseased areas both in natural background and in social background. It is indicated that rice and vegetables can accumulate water-soluble fluorine either in soils or in irrigating water,and different crops have different abilities of fixing fluorine. The contents of fluorine in different parts of vegetables in the fluorosis-diseased and fluorosis-free areas were statistically categorized. The results showed that the fluorine contents of roots,tubers,leaves and flowers of vegetables in the fluorosis-diseased areas are 3.56,1.17,3.07 and 3.23 mg/kg,respectively. However,comparisons showed that in the fluorosis-free areas,the fluorine contents are 2.17,0.70,1.91 and 2.52 mg/kg,respectively. Moreover,different parts of a crop also show significantly different fluorine fixation abilities. It is demonstrated that the fluorine contents of the strongly metabolic parts are relatively high. For example,the fluo-rine contents of roots,leaves and flowers of vegetables are much higher than those of stems. The fluorine fixation ability of seeds is very weak. In order to reduce the risk of human body’s exposure to fluoride,the impact of hot spring water on the capability of crops to fix fluorine should be reduced as much as possible. It is of great importance to prevent crops from being irrigated with hot spring water and it is advisable to grow crops with relatively low ca-pabilities to enrich fluorine,such as those with seeds or tubers as the main edible parts in the areas which are se-verely affected by hot spring water.LAN De WU Daishe LI Ping WANG Tengsheng CHEN Chengguang WANG Wuyi 2008Chinese Journal Of Geochemistry2008,27,4:10
20Role of P-selectin and anti-P-selectin monoclonal antibody in apoptosis during hepatic/renal ischemia-reperfusion injury显示文摘AIM To evaluale the potential role of P-selectinand anti-P-selectin monoclonal antibody(mAb)in apoptosis during hepatic/renal ischemia-reperfusion injury.METHODS Plasma P-selectin level,hepatic/renal P-selectin expression and cell apoptosiswere detected in rat model of hepatic/ renalischemia-reperfusion injury.ELISA,immunohist-ochemistry and TUNEL were used.Someischemia-reperfusion rats were treated with anti-P-selectin mAb.RESULTS Hepatic/renal function insuffic-iency,up-regulated expression of P-selectin inplasma and hepatic/renal tissue,hepatic/renalhistopathological damages and cell apoptosiswere found in rats with hepatic/renal ischemia-reperfusion injury,while these changes becameless conspicuous in animals treated with anti-P-selectin mAb.CONCLUSION P-selectin might mediateneutrophil infiltration and cell apoptosis andcontribute to hepatic/renal ischemia-reperfusioninjury,anti-P-selectin mAb might be an efficientapproach for the prevention and treatment ofhepatic/renal ischemia-reperfusion injury.Pei Wu Xiao Li Tong Zhou Ming Jun Zhang Jin Lian Chen Wei Ming Wang Nan Chen De Chang Dong 2000World Journal of Gastroenterology2000,6,2:10
