1Endoscopic mucosal resection of colorectal polyps in typical UK hospitals显示文摘AIM:To evaluate the outcomes of endoscopic mucosal resection(EMR) for colorectal polyps,with particular regard to procedural complications and recurrence rate,in typical United Kingdom(UK) hospitals that perform an average of about 25 colonic EMRs per year.METHODS:A total of 239 colorectal polyps(≥ 10 mm) resected from 199 patients referred to Rochdale Infirmary,Salford Royal Hospital and Royal Oldham Hospital for EMR between January 2003 and January 2009 were studied.RESULTS:The mean size of polyps resected was 19.6 ± 12.4 mm(range 10-80 mm).The overall major complication rate was 2.1%.Complications were less frequent with non-adenomas compared with the other groups(Pearson's χ 2 test,P < 0.0001).Resections of largersized polyps were more likely to result in complications(unpaired t-test,P = 0.021).Recurrence was associated with histology,with carcinoma-in-situ more likely to recur compared with low-grade dysplasia [hazard ratio(HR) 186.7,95% confidence interval(95% CI):8.81-3953.02,P = 0.001].Distal lesions were also more likely to recur compared with right-sided and transverse colon lesions(HR 5.93,95% CI:1.35-26.18,P = 0.019).CONCLUSION:EMR for colorectal polyps can be performed safely and effectively in typical UK hospitals.Stricter follow-up is required for histologically advanced lesions due to increased recurrence risk.Teegan R Lim Venkat Mahesh Salil Singh Benjamin HL Tan Mohamed Elsadig Nerukav Radhakrishnan Phil Conlong Chris Babbs Regi George 2010World Journal of Gastroenterology2010,16,42:11
2快速煅烧分解石灰石对其吸收CO_2和SO_2的影响显示文摘在加热过程中,应用一种新型的快速加热装置——铂膜反应器,及时准确地获得样品质量和颗粒温度,来研究石灰石的煅烧分解,并对石灰石加热速率高达750℃/s下的分解反应特性,及其对分解后产生的氧化钙吸收CO2和脱硫的化学反应特性进行了研究.实验表明,在初始加热阶段,高升温速率明显阻碍了煅烧分解的进行,这对分解后的CaO吸收CO2的效果影响不大.当加热速率升高时,石灰石分解后产生的CaO吸收CO2和脱硫过程中,钙利用率显著下降.阎常峰 陈勇 Grace John R Lim Jim 2007燃烧科学与技术2007,13,1:7
3石灰石的煅烧分解及其吸收二氧化碳机理显示文摘在天然气或合成气制氢过程中,借助于石灰石煅烧分解与石灰吸收二氧化碳的化学循环反应,去除反应产物,破坏化学平衡,可以连续地驱动化学反应进行,从而提高氢气的产率,同时控制温室气体二氧化碳的排放.在多功能热重反应器(TGR)内就化学循环反应过程中的颗粒尺寸、温度煅烧分解率等对吸附剂煅烧分解和吸收特性的影响进行了比较充分的实验研究.当吸收反应温度在500℃~620℃范围内时,CaO吸收二氧化碳的反应速率与石灰石中钙的利用率都维持在比较高的水平,石灰石分解后产生的氧化钙的利用率增长比石灰石的分解率增长慢,分解率高,吸热量也高,因此,简单地提高石灰石的分解率并不是提高石灰石钙利用率的最佳选择。阎常峰 陈勇 李小森 Grace J R Jim Lim 2006煤炭转化2006,29,2:7
4天然气自热重整模块化流化床膜反应器的测试显示文摘针对燃料电池等行业对分布式高纯度氢气的需求,研发了一种新型模块化流化床膜反应器用于中小规模天然气水蒸汽自热重整制氢。在一个天然气制氢测试平台上对该反应器进行了中试研究,测试了空气引入方式对床层温度均匀性的影响,钯膜组件及催化剂的工作性能,并将反应器尾气成分与平衡态最小自由能模型预测的结果进行了比较。测试结果表明该新型模块化流化床膜反应器适于天然气自热重整制氢。解东来 Adris A M Lim C J Grace J R 2009太阳能学报2009,30,5:6

6Hepatocellular carcinoma in patients with non-alcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is the most common chronic liver disease in the United States and represents an increasingly important etiology of hepatocellular carcinoma(HCC) with annual cumulative incidence rates ranging from 2% to 12% in cohorts of NAFLD cirrhosis. While the risk of progression of NAFLD to HCC remains higher among patients with fibrosis or cirrhosis, an increasing amount of literature describes NAFLD-HCC as a disease that can occur in the absence of cirrhosis. Efforts to characterize the pathogenesis of NAFLD-HCC have suggested mechanisms that strongly associate with states of hyperinsulinemia and chronic inflammation, cellular mechanisms including adaptive immune responses and hepatic progenitor cell populations, and genetic polymorphisms including mutations of PNPLA3. Current literature describes NAFLD-HCC mostly as a disease of late presentation with lower rates of receipt of curative therapy and worse prognosis. However, a growing body of evidence has reported comparable and potentially more favorable disease-free and overall survival rates among patients with NAFLD-HCC after receipt of curative treatment. This review summarizes current evidence of epidemiology, pathophysiology, disease presentation, demand and receipt of curative therapy, post-treatment outcomes, and overall survival of NAFLD-associated HCC.Carrie R Wong Mindie H Nguyen Joseph K Lim 2016World Journal of Gastroenterology2016,22,37:5

8Imaging of liver cancer显示文摘Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality.Ben Ariff Claire R Lloyd Sameer Khan Mohamed Shariff Andrew V Thillainayagam Devinder S Bansi Shahid A Khan Simon D Taylor-Robinson Adrian KP Lim 2009World Journal of Gastroenterology2009,15,11:4
