1小尺度土壤养分的空间变异及其影响因素探讨—以江苏省无锡市典型城乡交错区为例显示文摘以江苏省无锡市城乡交错区为例,在8km2范围内,采集102个土壤表层样,利用地统计学和G IS相结合的方法,研究了土壤全量和速效氮、磷、钾的空间变异特征,并对其影响因素进行了探讨。结果表明土壤养分空间变异程度从大到小依次为:土壤全氮>土壤全磷>土壤速效磷>土壤速效氮>土壤速效钾>土壤全钾。土壤全氮空间变异受到土壤类型的影响,土壤全磷的空间变异与居民点分布有关,土壤全钾空间变异与土壤粘粒关系最密切。土壤全量养分和相应的速效养分具有显著相关关系,在空间分布上,也分别存在不同程度的相似性。同时土壤全磷和土壤速效养分受土地利用影响也较大。研究还表明,城乡交错区土壤氮、磷流失风险增加,需要实施有效措施控制氮、磷肥料的过度施用。赵彦锋 史学正 于东升 黄标 王洪杰 赵永存 Ingrid born Karin Blombck 2006土壤通报2006,37,2:48
2Use of portal pressure studies in the management of variceal haemorrhage显示文摘Portal hypertension occurs as a complication of liver cirrhosis and complications such as variceal bleeding lead to significant demands on resources. Endoscopy is the gold standard method for screening cirrhotic patients however universal endoscopic screening may mean a lot of unnecessary procedures as the presence of oesophageal varices is variable hence a large time and cost burden on endoscopy units to carry out both screening and subsequent follow up of variceal bleeds. A less invasive method to identify those at high risk of bleeding would allow earlier prophylactic measures to be applied. Hepatic venous pressure gradient (HVPG) is an acceptable indirect measurement of portal hypertension and predictor of the complications of portal hypertension in adult cirrhotics. Varices develop at a HVPG of 10-12 mmHg with the appearance of other complications with HPVG > 12 mmHg. Variceal bleeding does not occur in pressures under 12 mmHg. HPVG > 20 mmHg measured early after admission is a significant prognostic indicator of failure to control bleeding varices, indeed early transjugular intrahepatic portosystemic shunt (TIPS) in such circumstances reduces mortality significantly. HVPG can be used to identify responders to medical therapy. Patients who do not achieve the suggested reduction targets in HVPG have a high risk of rebleeding despite endoscopic ligation and may not derive significant overall mortality benefit from endoscopic intervention alone, ultimately requiring TIPS or liver transplantation. Early HVPG measurements following a variceal bleed can help to identify those at risk of treatment failure who may benefit from early intervention with TIPS. Therefore, we suggest using HVPG measurement as the investigation of choice in those with confirmed cirrhosis in place of endoscopy for intitial variceal screening and, where indicated, a trial of B-blockade, either intravenously during the initial pressure study with assessment of response or oral therapy with repeat HVPG six weeks later. In those with elevated pressures, primary medical prophylaxis could be commenced with subsequent close monitoring of HVPG thus negating the need for endoscopy at this point. All patients presenting with variceal haemorrhage should undergo HVPG measurement and those with a gradient greater than 20 mmHg should be considered for early TIPS. By introducing portal pressure studies into a management algorithm for variceal bleeding, the number of endoscopies required for further intervention and follow up can be reduced leading to significant savings in terms of cost and demand on resources.Jennifer Addley Tony CK Tham William Jonathan Cash 2012World Journal of Gastrointestinal Endoscopy2012,4,7:37
3工业型城乡交错区农业土壤Cu、Zn、Pb和Cd的空间分布及影响因素研究显示文摘在江苏省无锡市工业型城乡交错区,选择8 km2区域,采集119个土壤样品,对土壤Cu、Zn、Pb、Cd及其有效态含量的空间分布和影响因素进行探讨。结果表明:该区土壤Cu、Zn、Pb、Cd含量和变异系数都明显增加,土壤有效态重金属含量与相应的全量重金属含量具有显著相关性。土壤Cu、Zn、Cd空间变异主要受到工业影响,但由于该区工业类型的多样性和工厂分布的分散性,Cu、Zn、Cd空间分布模式并不相同。本区土壤Pb的分布与工厂分布的相关性不大,但随与城市距离增加而降低。公路和土地利用与土壤重金属含量的关系表现不明显。该区工业污染对土壤重金属空间变异的影响可能掩盖了公路和土地利用等的影响,建议在城乡交错区合理安排工业布局以控制土壤受重金属污染的范围。赵彦锋 史学正 于东升 黄标 王洪杰 孙志英 赵永存 Ingrid born Karin Blombck 2007土壤学报2007,44,2:31

5Molecular mechanisms of viral hepatitis induced hepatocellular carcinoma显示文摘Chronic infection with viral hepatitis affects half a billion individuals worldwide and can lead to cirrhosis,cancer,and liver failure.Liver cancer is the third leading cause of cancer-associated mortality,of which hepatocellular carcinoma(HCC)represents 90%of all primary liver cancers.Solid tumors like HCC are complex and have heterogeneous tumor genomic profiles contributing to complexity in diagnosis and management.Chronic infection with hepatitis B virus(HBV),hepatitis delta virus(HDV),and hepatitis C virus(HCV)are the greatest etiological risk factors for HCC.Due to the significant role of chronic viral infection in HCC development,it is important to investigate direct(viral associated)and indirect(immune-associated)mechanisms involved in the pathogenesis of HCC.Common mechanisms used by HBV,HCV,and HDV that drive hepatocarcinogenesis include persistent liver inflammation with an impaired antiviral immune response,immune and viral protein-mediated oxidative stress,and deregulation of cellular signaling pathways by viral proteins.DNA integration to promote genome instability is a feature of HBV infection,and metabolic reprogramming leading to steatosis is driven by HCV infection.The current review aims to provide a brief overview of HBV,HCV and HDV molecular biology,and highlight specific viral-associated oncogenic mechanisms and common molecular pathways deregulated in HCC,and current as well as emerging treatments for HCC.Simmone D'souza Keith CK Lau Carla S Coffin Trushar R Patel 2020World Journal of Gastroenterology2020,26,38:25
6评估调质时间和温度对猪颗粒饲料淀粉糊化度和维生素沉积的影响显示文摘本论文研究了饲料加工的两个关键参数(调质温度和时间)对育肥猪颗粒饲料淀粉糊化度和维生素沉积的影响。日粮配方为含30%干酒糟及其可溶物的玉米-豆粕型基础日粮。整个试验中配方保持不变。本试验采用2×3双因子设计,调质温度分别为77℃和88℃,调质时间分别15秒、30秒和60秒。此外,本试验还设置一个对照组,对照组饲料不采用调质制粒工艺,而是采用粉料饲喂。因此,本试验共有7个处理组。采集调质后制粒前(热干粉)、制粒后冷却前(热制粒)、以及制粒冷却后(冷制粒)的样品,并分析这三种样品的总淀粉率。Lewis LL Stark CR Fahrenholz AC Bergstrom JR Jones CK 2015广东饲料2015,24,5:18
7中国城市地区成年人二手烟暴露水平及相关知识和态度调查显示文摘目的 了解中国城市地区成年人二手烟暴露水平及其相关知识态度.方法 利用全球成人烟草调查中国调查(GATS)、国际烟草控制政策评估项目中国调查(ITC)中有关二手烟暴露、禁烟规定、二手烟相关知识态度的变量,使用SAS软件计算率及其95%CI.结果 2项调查中调查对象报告的工作场所室内全面禁烟的比例均低于40%.调查对象报告在餐厅看到吸烟现象比例在各类场所中最高(83.4% ~ 95.6%),其次为工作场所(53.3% ~ 84.0%),在医疗卫生机构、学校、公共交通工具看到吸烟现象的比例较低.GATS调查中60.6%的吸烟者和68.5%的非吸烟者知晓二手烟导致肺癌,但只有三分之一的调查对象知晓二手烟导致成年人心脏病.ITC调查对象对二手烟危害的知晓率高于GATS,但知晓二手烟导致成年人心脏病的比例仅有58.2%.ITC调查对象对学校、出租车、医院、政府机构全面禁烟的支持率较高(>70%),但对工作场所全面禁烟的支持率仅有50.9%和60.9%.结论 中国城市地区室内工作场所全面禁烟的比例较低,二手烟暴露情况严重,公众对二手烟危害的认识以及对工作场所全面禁烟的支持率有待提高.冯国泽 姜垣 Zhao Luhua Meng Gang Wu Changbao Anne CK Quah Geoffrey T Fong 2014中华流行病学杂志2014,35,9:18
8太湖典型河网区地表水与沉积物氮、磷和重金属含量空间分异显示文摘将无锡城乡交错区河网分为城镇生活区水巷、工业区主河道、农业区主河道、农业区支流和鱼塘5种类型区。通过秋季(旱季)和夏季(雨季)2次采样,研究氮、磷和Cu、Zn、Pb、Cr、Cd在地表水和沉积物中的含量及其空间变化。结果表明:(1)城乡交错区地表水氮、磷来源于生活污染和工业污染的比例大于农田,同时具有来源分散、污染面广的特征。(2)由于城镇地表径流和工业活动影响,各类型区地表水重金属含量均有不同程度提高。但地表水重金属主要沿主河道迁移,旱季和雨季主河道重金属含量均大于农业区支流,而且随着与城镇距离增加,主河道沉积物重金属含量迅速降低,重金属污染影响范围较小。(3)与重金属相比,地表水氮、磷污染仍是太湖水网区主要的环境问题。但城镇及其周围河流沉积物中富集的重金属含量很高,其潜在环境风险不容忽视。赵彦锋 史学正 于东升 黄标 王洪杰 Ingrid born Karin Blombck 2007生态与农村环境学报2007,23,1:13

12台风伤害及其影响因素的现场流行病学研究显示文摘目的分析台风伤害的危险因素。方法采用现场流行病学调查方法,1:2配对的病例对照研究。对照组选伤害者邻居,按照同职业、同村庄、同性别和年龄±5岁配对。结果台风造成392人受伤住院治疗,50人死亡。伤害罹患率为27.3/10万,伤害致死率为11.3%,伤害死亡率3.1/10万。调查了209名受伤者和31名死亡者。发现伤害主要发生在台风来临前,其中台风来临前1~6小时之间有病例155例,占64.6%。209例伤害病例中,67.5%的病例曾得到过台风预警,但138名应答者中重视预警的只有47人,仅占34.0%。发现“台风来临时不在家中”[调整OR值(MH)=3.9 (95%CI:1.9~7.7)]、“台风来临前未得到预警”[调整OR值(MH)=3.3(95%CI:1.3~8.6)]和“虽得到预警但不重视”[调整OR值(MH)=17(95%CI:4.2~68)]是台风伤害的危险因素。结论外出、不重视预警是台风伤害的危险因素,应加强台风来临的预警宣传力度。龚震宇 柴程良 屠春雨 林君芬 高奕 邱银伟 曾光 Robert E.Fontaine Lee CK 何凡 陈坤 2006中华流行病学杂志2006,27,9:10
13Protective effects of ischemic preconditioning and application of lipoic acid prior to 90 min of hepatic ischemia in a rat model显示文摘AIM: To compare different preconditioning strategies to protect the liver from ischemia/reperfusion injury focusing on the expression of pro- and anti-apoptotic proteins. Interventions comprised different modes of ischemic preconditioning (IP) as well as pharmacologic pretreatment by α-lipoic acid (LA). METHODS: Several groups of rats were compared: sham operated animals, non-pretreated animals (nt), animals receiving IP (10 min of ischemia by clamping of the portal triad and 10 min of reperfusion) prior to sustained ischemia, animals receiving selective ischemic preconditioning (IPsel, 10 min of ischemia by selective clamping of the ischemic lobe and 10 min of reperfusion) prior to sustained ichemia, and animals receiving 500 μmol α-LA injected i.v. 15 min prior to the induction of 90 min of selective ischemia. RESULTS: Cellular damage was decreased only in the LA group. TUNEL-positive hepatocytes as well as necrotic hepatocyte injury were also decreased only by LA (19 ± 2 vs 10 ± 1, P < 0.05 and 29 ± 5 vs 12 ± 1, P < 0.05). Whereas caspase 3- activities in liver tissue were unchanged, caspase 9- activity in liver tissue was decreased only by LA pretreatment (3.1 ± 0.3 vs 1.8 ± 0.2, P < 0.05). Survival rate as the endpoint of liver function was increased after IP and LA pretreatment but not after IPsel. Levels of lipid peroxidation (LPO) in liver tissue were decreased in the IP as well as in the LA group compared to the nt group. Determination of pro- and anti-apoptotic proteins showed a shift towardsanti-apoptotic proteins by LA. In contrast, both our IP strategies failed to influence apototic cell death. CONCLUSION: IP, consisting of 10 min of ischemia and 10 min of reperfusion, protects only partly against ischemia/reperfusion injury of the liver prior to 90 min of selective ischemia. IPsel did not influence ischemic tolerance of the liver. LA improved tolerance to ischemia, possibly by downregulation of pro-apoptotic Bax.Friedrich Duenschede Kirsten Erbes Nina Riegler Patrick Ewald Achim Kircher Stefanie Westermann Arno Schad Imke Miesmer Simon Albrecht-Schck Ines Gockel Alexandra K Kiemer Theodor Junginger 2007World Journal of Gastroenterology2007,13,27:8
14Endoscopic placement of enteral feeding tubes显示文摘Malnutrition is common in patients with acute and chronic illness.Nutritional management of these malnourished patients is an essential part of healthcare.Enteral feeding is one component of nutritional support.It is the preferred method of nutritional support in patients that are not receiving adequate oral nutrition and have a functioning gastrointestinal tract(GIT).This method of nutritional support has undergone progression over recent times.The method of placement of enteral feeding tubes has evolved due to development of new feeding tubes and endoscopic technology.Enteral feeding can be divided into methods that provide short-term and long-term access to the GIT.This review article focuses on the current range of methods of gaining access to the GIT to provide enteral feed.Gerard P Rafferty Tony CK Tham 2010World Journal of Gastrointestinal Endoscopy2010,2,5:7
15Small bowel capsule endoscopy in patients with cardiac pacemakers and implantable cardioverter defibrillators:Outcome analysis using telemetry review显示文摘AIM:To determine if there were any interactions between cardiac devices and small bowel capsules secondary to electromagnetic interference (EMI) in patients who have undergone small bowel capsule endoscopy (SBCE).METHODS:Authors conducted a chart review of 20 patients with a cardiac pacemaker (CP) or implantable cardioverter defibrillator (ICD) who underwent continuous electrocardiographic monitoring during their SBCE from 2003-2008.authors searched for unexplained electrocardiogram (ECG) findings,changes in CP andICD set parameters,any abnormality in transmitted capsule data,and adverse clinical events.RESULTS:There were no adverse events or hemodynamically significant arrhythmias reported.CP and ICD set parameters were preserved.The majority of ECG abnormalities were also found in pre-or post-SBCE ECG tracings and the CP behavior during arrhythmias appeared appropriate.Two patients seemed to have episodes of undersensing by the CP.However,similar findings were documented in ECGs taken outside the time frame of the SBCE.One patient was observed to have a low signal encountered from the capsule resulting in lack of localization,but no images were lost.CONCLUSION:Capsule-induced EMI remains a possibility but is unlikely to be clinically important.CPinduced interference of SBCE is also possible,but is infrequent and does not result in loss of images transmitted by the capsule.Justin R Cuschieri Mohammed N Osman Richard CK Wong Amitabh Chak Gerard A Isenberg 2012World Journal of Gastrointestinal Endoscopy2012,4,3:6
16Construction of energy transfer model of C-phycocyanin and allophycocyanin from Spirulina platensis显示文摘PHYCOBILIPROTEINS. which include phycoerythrin, phycocyanin, phycoerythroeyanin and allophycocyanin, are intensively coloured, highly fluorescent, water soluble chromoproteins. They are composed of at least two dissimilar polypeptides, α and β subunits, in a molar ratio of 1:1. The subunits possess linear tetrapyrrole prosthetic groups covalently linked to the primary structure via cysteine thioether linkages. In blue-green and red algae, phycobiliproteins occur in a supramolecular structure, the phycobilisome, located on the surface of thylakoid toWang, GC Zhou, BC Zeng, CK 1997Chinese Science Bulletin1997,42,1:6
17Expression of co-stimulator 4-1BB molecule in hepatocellular carcinoma and adjacent non-tumor liver tissue,and its possible role in tumor immunity显示文摘AIM:To investigate the expression of 4-1BB molecule in hepatocellular carcinoma (HCC) and its adjacent tissues.METHODS:Reverse transcription-polymerase chain reaction (RT-PCR) was used to determine the gene expression of 4-1BB in hepatocarcinoma and its adjacent tissues,and peripheral blood mononuclear cells (PBMCs) from both HCC and health control groups.Flow cytometry was used to analyse the phenotypes of T cell subsets from the blood of HCC patients and healthy volunteers,and further to determine whether 4-1BB molecules were also expressed on the surface of CD4+ and CD8+ T cells. The localization of 4-1BB proteins on tumor infiltrating T cells was determined by direct immunofluorescence cytochemical staining and detected by confocal microscopy.RESULTS:4-1BB mRNA, which was not detectable in normal liver,was found in 19 liver tissues adjacent to tumor edge(<1.0cm).Low expression of 4-1BB mRNA was shown in 8 tumor tissues and 6 liver tissues located within 1 to 5cm away from tumor edge. In PBMCs, 4-1BB mRNA was almost not detected. Percentage of CD4^+, CD8^+ and CD3^+/CD25^+ T cells, as well as ratio of CD4 to CD8 revealed no difference between groups (P>0.05,respectively),while a significant lower percentage of CD3^+ T cell was found in HCC group as compared to healthy control group (P<0.05).However, 4-1BB molecules were almost not found on the surface of CD4+ and CD8+ T cells in HCC and healthy control group.Double-staining of 4-1BB^+/CD4^+ and 4-1BB^+/CD8^+ immunofluorescence on tumor infiltrating T cells was detected in 13 liver tissues adjacent to tumor edge (<1.0cm) by confocal microscopy.CONCLUSION: Although HCC may escape from immune attack by weak immunogenicity or downregulated expression of MHC-1 molecules on the tumor cell surface,tumor infiltrating T cells can be activated via other costimulatory signal pathways to exert a limited antitumor effect on local microenvironment. The present study also implicates that modulating 4-1BB/4-1BBL costimulatory pathway may be an effective immunotherapy strategy to augment the host response.Wan, YL Zheng, SS Zhao, ZC Li, MW Jia, CK Zhang, H 2004World Journal of Gastroenterology2004,10,2:6

19二十碳五烯酸对三种肝癌细胞系作用的实验研究显示文摘目的 探讨二十碳五烯酸 (eicosapentaenoicacid ,EPA)对 3种肝癌细胞系作用。方法EPA作用于HepG2 (携带有野生型p5 3基因 )、Huh7(携带有突变型p5 3基因 )和Hep3B(p5 3基因缺失 )这 3种肝癌细胞系 ,通过细胞计数、DNA电泳、流式细胞技术和末端转移酶标记技术等来检测EPA对这 3种细胞系的作用和可能的机制。结果 EPA主要是通过诱导HepG2肝癌细胞系的细胞凋亡来抑制其生长 ,而且这种抑制作用呈现出时间和剂量依赖的关系 ,而且同时发现EPA对于Huh7和Hep3B这两种肝癌细胞系无明显抑制作用。结论 细胞凋亡的诱导可能是EPA抑制HepG2肝癌细胞系生长的主要机制 ,而且p5 3基因可能参与EPA诱导HepG2细胞系细胞凋亡的过程。王蓬 陈孝平 PBS Lai CK leow Joseph W Y Lau 2001中华普通外科杂志2001,16,1:4
20气候变化和紫外线辐射对北极淡水鱼类及溯河产卵鱼类渔业的影响显示文摘北极淡水鱼类和洄游鱼类渔业为北方经济做出了重大贡献。但是,对于淡水水体,气候变化和增长的紫外线辐射对渔业产生的巨大影响有3个方面:可获鱼的数量、质量和捕捞成功率。因此,在这些影响发生作用之际,可能需要实质有效的适应行为以引导北极未来的渔业走向可持续性。当务之急是为商业渔业选择灵活和快速反应的'适宜管理'方式;改变生计渔业的当地土地和资源利用模式;改变很多休闲渔业的特性、管理方式和地点。总的来说,在气候变化及其对北极淡水水域和生物区影响的复杂性和不确定性情况下,为保证生态系统和主导鱼种有足够的恢复力和应对将来变化的能力,需要对渔业的各个方面实施更保守的管理办法。James D.Reist Frederick J.Wrona Terry D.Prowse J.Brian Dempson Michael Power Günter Kck Theresa J.Carmichael Chantelle D.Sawatzky Hannu Lehtonen Ross F.Tallman 曾首英 2006AMBIO-人类环境杂志2006,35,7:4
