| 1 | Endoscopy in screening for digestive cancer显示文摘The aim of this study is to describe the role of endoscopy in detection and treatment of neoplastic lesions of the digestive mucosa in asymptomatic persons.Esophageal squamous cell cancer occurs in relation to nutritional deficiency and alcohol or tobacco consumption.Esophageal adenocarcinoma develops in Barrett's esophagus,and stomach cancer in chronic gastric atrophy with Helicobacter pylori infection.Colorectal cancer is favoured by a high intake in calories,excess weight,low physical activity.In opportunistic or individual screening endoscopy is the primary detection procedure offered to an asymptomatic individual.In organized or mass screening proposed by National Health Authorities to a population,endoscopy is performed only in persons found positive to a filter selection test.The indications of primary upper gastrointestinal endoscopy and colonoscopy in opportunistic screening are increasingly developing over the world.Organized screening trials are proposed in some regions of China at high risk for esophageal cancer;the selection test is cytology of a balloon or sponge scrapping;they are proposed in Japan for stomach cancer with photofluorography as a selection test;and in Europe,America and Japan;for colorectal cancer with the fecal occult blood test as a selection test.Organized screening trials in a country require an evaluation:the benefit of the intervention assessed by its impact on incidence and on the 5 year survival for the concerned tumor site;in addition a number of bias interfering with the evaluation have to be controlled.Drawbacks of screening are in the morbidity of the diagnostic and treatment procedures and in overdetection of none clinically relevant lesions.The strategy of endoscopic screening applies to early cancer and to benign adenomatous precursors of adenocarcinoma.Diagnostic endoscopy is conducted in 2 steps:at first detection of an abnormal area through changes in relief,in color or in the course of superficial capillaries;then characterization of the morphology of the lesion according to the Paris classification and prediction of the risk of malignancy and depth of invasion,with the help of chromoscopy,magnification and image processing with neutrophil bactericidal index or FICE.Then treatment decision offers 3 options according to histologic prediction:abstention,endoscopic resection,surgery.The rigorous quality control of endoscopy will reduce the miss rate of lesions and the occurrence of interval cancer. | René Lambert | 2012 | World Journal of Gastrointestinal Endoscopy2012,4,12: | 9 |

| 13 | 轨道车辆继电器的技术优势显示文摘电磁机械式继电器有时会被认为是过时的,但是电磁机械式继电器技术在轨道车辆方面是有优势的。继电器相关的设计、整改和维护都很简单,而且其安全性和稳固性使得这种继电器非常适合那种每天都需要工作的电路环境。在轨道车辆的运营中,稳定性是个关键因素。因此轨道交通行业涉及的技术都是被久经验证过的,这样就可能让人觉得是比较“守旧的”。尽管如此,大量新的车辆功能在产生而且很多新兴的系统快速地被引入到轨道车辆上来。微处理器的使用导致大家对以往技术的采用和关注在减少。于此同时,很多学者们也不再考虑以往的技术。 | RenéKnuvers | 2020 | 世界轨道交通2020,,8: | 0 |
| 14 | 哈佛法学院 外部董事“阴暗面”显示文摘随着本世纪初一系列公司丑闻的发生,公司治理改革开始聚焦于董事会外部董事的表现。美国证券交易所上市标准明确要求董事会中外部董事应占多数。很多国家也对董事会外部董事的比例,以及提名委员会、薪酬制定委员会和审计委员会中外部董事的比例做了明文规定。 | René Stulz | 2010 | 董事会2010,,8: | 0 |
| 15 | 轨道车辆的继电器可靠性技术显示文摘可靠性是铁路技术的重要组成部分,是列车安全性和可用性的前提。选择正确的部件,在事故发生之前对故障进行预测对铁路行业至关重要。技术管理人员最重要的任务之一就是保证列车运行的安全性,提高其可用性,这也是设计工程师、车辆运营商和维修人员同样需要关注的。安全性及可用性的根源在于系统及其部件的可靠性。部件故障通常会引起一系列问题,最终可能导致列车处于不安全状态或者列车(部分)无法使用。 | RenéKnuvers | 2020 | 世界轨道交通2020,,10: | 0 |
| 16 | 常青的邓丽君、蔡琴显示文摘怀旧曲目唱片在唱片市场里是一个长青品种,有着丰富人生阅历的人对此类唱片尤为青睐,因为那些经典歌曲是他们激情生涯中不绝于耳边的记忆,而就中文歌曲演唱而言,邓丽君与蔡琴,是两个必不可少的名字。 | René | 2006 | 音响世界2006,,8: | 0 |
| 17 | DG最新“聚光灯”系列显示文摘纵观20世纪的歌唱技艺发展史,六、七十年是一个黄金时期,此时各种歌唱流派已基本定形,进入了一个相对成熟的阶段,一大批伟大的歌手忙碌地活跃于乐坛当中,同一时期,唱片工业也处于颠峰时期,正是相得益彰,那些业已成名的艺术家开始进入录音棚,从而留下他们光辉岁月的印证。 | René | 2006 | 音响世界2006,,8: | 0 |
| 18 | 基于新冠肺炎疫情影响的风险管理启示显示文摘本文将围绕新冠肺炎疫情的影响,主要介绍其在风险管理方面所带来的四点启示。第一,新冠肺炎疫情是现实中发生的小概率事件,在风险管理领域,人们不太擅长应对此类事件,运用理性决策模型来应对此类事件至关重要。第二,2020年的市场危机与2008年有很大差异,差异的部分原因是全球金融危机后的监管要求。第三,拥有高灵活性资产负债表的公司较少受此类事件的影响。最后则是介绍金融机构资金稳定的重要性。本文将通过一个案例,详细介绍在金融危机期间,资金不稳定造成部分金融科技行业明显表现不佳。 | René M.Stulz | 2022 | 上海保险2022,,10: | 0 |
