2低位内镜检查可减少结直肠癌的长期发生率和死亡率显示文摘电子结肠镜检查有助于预防结直肠癌发生,其保护作用的强度和持续时间,特别是对近端结肠的保护作用还需进一步研究。美国麻省总医院胃肠科的Chan博士等人对此进行了研究,他们发现结肠镜检查是有效的结直肠癌筛查方法。研究人员检验了Nurses''健康研究及医疗专业随访研究的受试人群中低位结肠内镜检查(1988至2008,两年一次更新)与结直肠癌发生率(至2010年6月)及结直肠癌死亡率(至2012年6月)之间的相关性。研究由此得出结论:电子结肠镜检查与远端结直肠癌发生率下降相关;电子结肠镜检查与近端结肠癌发生率的适度下降相关。经电子结肠镜检查筛查与结直肠癌死亡率下降相关;而仅电子结肠镜检查与近端结肠癌死亡率的下降相关。与从未接受电子结肠镜检查或电子结肠镜检查超过5年后诊断为结直肠癌的患者相比,电子结肠镜检查后5年内诊断为结直肠癌的患者更易出现CpG岛甲基化现象和微卫星不稳定性。Nishihara R Wu K Lochhead P 2013中华结直肠疾病电子杂志2013,2,4:52
3History of the infantile hepatic hemangioma:From imaging to generating a differential diagnosis显示文摘We aim to provide an up-to-date summary of infantile hepatic hemangioma(IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver.Eligible peer-reviewed articles on hepatic infantile hemangiomas,published between 2000 and 2015,were reviewed for this study.IHH is the most common hepatic vascular tumor in children.Once a liver mass is identified in an infant,the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma,hepatoblastoma,metastatic neuroblastoma,so careful physical examination,imaging studies,and,if indicated,tumor markers and biopsy,are of pivotal importance to ascertain the correct diagnosis.Despite the benign nature of IHHs,some of these lesions may demand medical and/or surgical intervention,especially for multiple and diffuse IHH.Complications can include hepatomegaly,hypothyroidism and cardiac failure.Therefore,a close follow-up is required until complete involution of the lesions.We propose an algorithm to guide the physicians towards the proper management of hepatic lesions.Maria Gnarra Gerald Behr Alison Kitajewski June K Wu Sudha A Anupindi Carrie J Shawber Nick Zavras Dimitrios Schizas Chris Salakos Konstantinos P Economopoulos 2016World Journal of Clinical Pediatrics2016,5,3:27
4Effect of ginger Effect of ginger on gastric motility and symptoms of functional dyspepsiaon gastric motility and symptoms of functional dyspepsia显示文摘AIM:To evaluate the effects of ginger on gastric motility and emptying,abdominal symptoms,and hormones that influence motility in dyspepsia.METHODS:Eleven patients with functional dyspepsia were studied twice in a randomized double-blind manner.After an 8-h fast,the patients ingested three capsules that contained ginger(total 1.2 g) or placebo,followed after 1 h by 500 mL low-nutrient soup.Antral area,fundus area and diameter,and the frequency of antral contractions were measured using ultrasound at frequent intervals,and the gastric half-emptying time was calculated from the change in antral area.Gastrointestinal sensations and appetite were scored using visual analog questionnaires,and blood was taken for measurement of plasma glucagon-like peptide-1(GLP-1),motilin and ghrelin concentrations,at intervals throughout the study.RESULTS:Gastric emptying was more rapid after ginger than placebo [median(range) half-emptying time 12.3(8.5-17.0) min after ginger,16.1(8.3-22.6) min after placebo,P ≤ 0.05].There was a trend for more antral contractions(P = 0.06),but fundus dimensions and gastrointestinal symptoms did not differ,nor did serum concentrations of GLP-1,motilin and ghrelin.CONCLUSION:Ginger stimulated gastric emptying and antral contractions in patients with functional dyspepsia,but had no impact on gastrointestinal symptoms or gut peptides.Ming-Luen Hu Christophan K Rayner Keng-Liang Wu Seng-Kee Chuah Wei-Chen Tai Yeh-Pin Chou Yi-Chun Chiu King-Wah Chiu Tsung-Hui Hu 2011World Journal of Gastroenterology2011,17,1:19

8Autophagy inhibition by chloroquine sensitizes HT-29 colorectal cancer cells to concurrent chemoradiation显示文摘AIM:To investigate whether the inhibition of autophagy by chloroquine(CQ)sensitizes rectal tumors to radiation therapy(RT)or concurrent chemoradiation(chemoRT).METHODS:In vitro,HCT-116 and HT-29 colorectal cancer(CRC)cell lines were treated as following:(1)PBS;(2)CQ;(3)5-fluorouracil(5-FU);(4)RT;(5)CQ and RT;(6)5-FU and RT;(7)CQ and 5-FU;and(8)5-FU and CQ and RT.Each group was then exposed to various doses of radiation(0-8 Gy)depending on the experiment.Cell viability and proliferative capacity were measured by3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)and clonogenic assays.Clonogenic survivalcurves were constructed and compared across treatment groups.Autophagy status was determined by assessing the LC3-Ⅱto LC3-Ⅰratio on western blot analysis,autophagosome formation on electron microscopy and identification of a perinuclear punctate pattern with GFPlabeled LC3 on fluorescence microscopy.Cell cycle arrest and cell death were evaluated by FACS and AnnexinⅤanalysis.All experiments were performed in triplicate and statistical analysis was performed by the student’s t test to compare means between treatment groups.RESULTS:RT(2-8 Gy)induced autophagy in HCT-116and HT-29 CRC cell lines at 4 and 6 h post-radiation,respectively,as measured by increasing LC3-Ⅱto LC3-Ⅰratio on western blot.Additionally,electron microscopy demonstrated autophagy induction in HT-29 cells24 h following irradiation at a dose of 8 Gy.Drug treatment with 5-FU(25μmol/L)induced autophagy and the combination of 5-FU and RT demonstrated synergism in autophagy induction.CQ(10μmol/L)alone and in combination with RT effectively inhibited autophagy and sensitized both HCT-116 and HT-29 cells to treatment with radiation(8 Gy;P<0.001 and 0.00001,respectively).Significant decrease in clonogenic survival was seen only in the HT-29 cell line,when CQ was combined with RT at doses of 2 and 8 Gy(P<0.5 and P=0.05,respectively).There were no differences in cell cycle progression or Annexin V staining upon CQ addition to RT.CONCLUSION:Autophagy inhibition by CQ increases CRC cell sensitivity to concurrent treatment with 5-FU and RT in vitro,suggesting that addition of CQ to chemoRT improves CRC treatment response.Caitlin A Schonewolf Monal Mehta Devora Schiff Hao Wu Bruce G Haffty Vassiliki Karantza Salma K Jabbour 2014World Journal of Gastrointestinal Oncology2014,6,3:12
9Comparative evaluation of intragastric bile acids and hepatobiliary scintigraphy in the diagnosis of duodenogastric reflux显示文摘AIM:To assess the diagnostic value of a combination of intragastric bile acids and hepatobiliary scintigraphy in the detection of duodenogastric reflux(DGR).METHODS:The study contained 99 patients with DGR and 70 healthy volunteers who made up the control group.The diagnosis was based on the combination of several objective arguments:a long history of gastric symptoms(i.e.,nausea,epigastric pain,and/or bilious vomiting) poorly responsive to medical treatment,gastroesophageal reflux symptoms unresponsive to protonpump inhibitors,gastritis on upper gastrointestinal(GI) endoscopy and/or at histology,presence of a bilious gastric lake at > 1 upper GI endoscopy,pathologic 24-h intragastric bile monitoring with the Bilitec device.Gas-tric juice was aspirated in the GI endoscopy and total bile acid(TBA),total bilirubin(TBIL) and direct bilirubin(DBIL) were tested in the clinical laboratory.Continuous data of gastric juice were compared between each group using the independent-samples Mann-Whitney U-test and their relationship was analysed by Spearman's rank correlation test and Fisher's linear discriminant analysis.Histopathology of DGR patients and 23 patients with chronic atrophic gastritis was compared by clinical pathologists.Using the Independent-samples Mann-Whitney U-test,DGR index(DGRi) was calculated in 28 patients of DGR group and 19 persons of control group who were subjected to hepatobiliary scintigraphy.Receiver operating characteristic curve was made to determine the sensitivity and specificity of these two methods in the diagnosis of DGR.RESULTS:The group of patients with DGR showed a statistically higher prevalence of epigastric pain in comparison with control group.There was no significant difference between the histology of gastric mucosa with atrophic gastritis and duodenogastric reflux.The bile acid levels of DGR patients were significantly higher than the control values(Z:TBA:-8.916,DBIL:-3.914,TBIL:-6.197,all P < 0.001).Two of three in the DGR group have a significantly associated with each other(r:TBA/DBIL:0.362,TBA/TBIL:0.470,DBIL/TBIL:0.737,all P < 0.001).The Fisher's discriminant function is followed:Con:Y = 0.002TBA + 0.048DBIL + 0.032TBIL 0.986;Reflux:Y = 0.012TBA + 0.076DBIL + 0.089TBIL-2.614.Eighty-four point zero five percent of original grouped cases were correctly classified by this method.With respect to the DGR group,DGRi were higher than those in the control group with statistically significant differences(Z =-5.224,P < 0.001).Twenty eight patients(59.6%) were deemed to be duodenogastric reflux positive by endoscopy,as compared to 37 patients(78.7%) by hepatobiliary scintigraphy.CONCLUSION:The integrated use of intragastric bile acid examination and scintigraphy can greatly improve the sensitivity and specificity of the diagnosis of DGR.Teng-Fei Chen Praveen K Yadav Rui-Jin Wu Wei-Hua Yu Chang-Qin Liu Hui Lin Zhan-Ju Liu 2013World Journal of Gastroenterology2013,19,14:12
10膳食中钠(盐)与血压的关系及其他膳食因素可能的调节作用显示文摘现有资料表明,膳食钠(盐)与血压直接相关。以往大多数研究结果来自缺乏膳食数据的研究;因此,这种钠-血压关系是否受其他膳食因素调节尚不清楚。国际宏量/微量营养素和血压研究(international study on macro/micronutrients and blood pressure,INTERMAP)结果显示,在控制多种非膳食因素情况下,年龄40~59岁的男性和女性4680人(中国、日本、英国和美国的17个人口样本)的血压与24h尿钠排泄和尿钠/钾直接相关。刘莉 叶鹏 Stamler J Chan Q Daviglus ML Dyer AR Van Horn L Garside DB Miura K Wu Y Ueshima H Zhao L Elliott P INTERMAP Research Group 2018中华高血压杂志2018,26,4:8
11大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini 2021英国医学杂志中文版2021,24,8:7

17Numerical Analysis of Structural Progressive Collapse to Blast Loads显示文摘After the progressive collapse of Ronan Point apartment in UK in 1968, intensive research effort had been spent on developing guidelines for design of new or strengthening the existing structures to prevent progressive collapse. However, only very few building design codes provide some rather general guidance, no detailed design requirement is given. Progressive collapse of the Alfred P. Murrah Federal building in Oklahoma City and the World Trade Centre (WTC) sparked again tremendous research interest on progressive collapse of structures. Recently, US Department of Defence (DoD) and US General Service Administration (GSA) issued guidelines for structure progressive collapse analysis. These two guidelines are most commonly used, but their accuracy is not known. This paper presents numerical analysis of progressive collapse of an example frame structure to blast loads. The DoD and GSA procedures are also used to analyse the same example structure. Numerical results are compared and discussed. The accuracy and the applicability of the two design guidelines are evaluated.HAO Hong WU Chengqing LI Zhongxian ABDULLAH A K 2006Transactions of Tianjin University2006,12,B09:6
18Reactivation of hepatitis B after liver transplantation: Current knowledge, molecular mechanisms and implications in management显示文摘Chronic hepatitis B(CHB) is a major global health problem affecting an estimated 350 million people with more than 786000 individuals dying annually due to complications, such as cirrhosis, liver failure and hepatocellular carcinoma(HCC). Liver transplantation(LT) is considered gold standard for treatment of hepatitis B virus(HBV)-related liver failure and HCC. However, post-transplant viral reactivation can be detrimental to allograft function, leading to poor survival. Prophylaxis with high-dose hepatitis B immunoglobulin(HBIG) and anti-viral drugs have achieved remarkable progress in LT by suppressingviral replication and improving long-term survival. The combination of lamivudine(LAM) plus HBIG has been for many years the most widely used. However, life-long HBIG use is both cumbersome and costly, whereas long-term use of LAM results in resistant virus. Recently, in an effort to develop HBIG-free protocols, high potency nucleos(t)ide analogues, such as Entecavir or Tenofovir, have been tried either as monotherapy or in combination with low-dose HBIG with excellent results. Current focus is on novel antiviral targets, especially for covalently closed circular DNA(ccc DNA), in an effort to eradicate HBV infection instead of viral suppression. However, there are several other molecular mechanisms through which HBV may reactivate and need equal attention. The purpose of this review is to address post-LT HBV reactivation, its risk factors, underlying molecular mechanisms, and recent advancements and future of anti-viral therapy.Ranjit Chauhan Shilpa Lingala Chiranjeevi Gadiparthi Nivedita Lahiri Smruti R Mohanty Jian Wu Tomasz I Michalak Sanjaya K Satapathy 2018World Journal of Hepatology2018,10,3:5
