1冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi 2019中华心血管病杂志2019,47,1:17

3抗菌蜂蜜预防腹膜透析相关感染:一项随机对照试验显示文摘背景 目前缺少指导预防腹膜透析相关感染策略的研究证据。抗菌蜂蜜作为一种新型、廉价、有效的局部预防性使用的药物,不会诱导细菌耐药。因此,我们评估,对鼻内定植金黄色葡萄球菌的患者,与同时进行腹膜管外出口部位常规护理加上鼻内莫匹罗星去定植的方法相比,腹膜管外出口部位每日使用蜂蜜,是否会延迟首次出现腹膜透析相关感染的时间。Johnson D W Badve S V Pascoe E M 陈玉华 2014中国感染控制杂志2014,13,2:7
4慢性淋巴细胞白血病诊治指南显示文摘流行病学 慢性淋巴细胞白血病(CLL)在西方国家很常见,占65岁以上白血病患者的65%.中位发病年龄65~70岁.30岁以下极为罕见,但20%~30%病例于55岁前发病,年发病率约3/10万.欧洲、澳大利亚、北美白人以及黑人的发病率是印度、中国及日本的20~30倍.男女之比约2:1.无确凿证据显示,接触化学物质和射线、饮食、吸烟、病毒感染和自身免疫性疾病为本病的高危因素,但患者一级和二级亲属淋巴系统恶性肿瘤发病率增高.许多家族尚存在患者后代发病年龄更早、病情更重的现象.经治和未治患者第二肿瘤发病率增高.Oscier D Fegan C Hillman P Illide T Johnson S Maguir P Matutes M Milligan D 孙蕾 高举 2005国外医学(输血及血液学分册)2005,28,1:6
5Artificial intelligence in gastroenterology: A state-of-the-art review显示文摘The development of artificial intelligence(AI)has increased dramatically in the last 20 years,with clinical applications progressively being explored for most of the medical specialties.The field of gastroenterology and hepatology,substantially reliant on vast amounts of imaging studies,is not an exception.The clinical applications of AI systems in this field include the identification of premalignant or malignant lesions(e.g.,identification of dysplasia or esophageal adenocarcinoma in Barrett’s esophagus,pancreatic malignancies),detection of lesions(e.g.,polyp identification and classification,small-bowel bleeding lesion on capsule endoscopy,pancreatic cystic lesions),development of objective scoring systems for risk stratification,predicting disease prognosis or treatment response[e.g.,determining survival in patients post-resection of hepatocellular carcinoma),determining which patients with inflammatory bowel disease(IBD)will benefit from biologic therapy],or evaluation of metrics such as bowel preparation score or quality of endoscopic examination.The objective of this comprehensive review is to analyze the available AI-related studies pertaining to the entirety of the gastrointestinal tract,including the upper,middle and lower tracts;IBD;the hepatobiliary system;and the pancreas,discussing the findings and clinical applications,as well as outlining the current limitations and future directions in this field.Paul T Kröner Megan ML Engels Benjamin S Glicksberg Kipp W Johnson Obaie Mzaik Jeanin E van Hooft Michael B Wallace Hashem B El-Serag Chayakrit Krittanawong 2021World Journal of Gastroenterology2021,27,40:6
6Insulin-like growth factor binding protein-5 influences pancreatic cancer cell growth显示文摘AIM: To investigate the functional significance of insulin-like growth factor binding protein-5 (IGFBP-5) overexpression in pancreatic cancer (PaC).METHODS: The effects of IGFBP-5 on cell growth were assessed by stable transfection of BxPC-3 and PANC-1 cell lines and measuring cell number and DNA synthesis. Alterations in the cell cycle were assessed by flow cytometry and immunoblot analyses. Changes in cell survival and signal transduction were evaluated after mitogen activated protein kinase and phosphatidylinositol 3-kinase (PI3K) inhibitor treatment.RESULTS: After serum deprivation, IGFBP-5 expression increased both cell number and DNA synthesis in BxPC-3 cells, but reduced cell number in PANC-1 cells. Consistent with this observation, cell cycle analysis of IGFBP-5-expressing cells revealed accelerated cell cycle progression in BxPC-3 and G2/M arrest of PANC-1 cells. Signal transduction analysis revealed that Akt activation was increased in BxPC-3, but reduced in PANC-1 cells that express IGFBP-5. Inhibition of PI3K with LY294002 suppressed extracellular signal-regulated kinase-1 and -2 (ERK1/2) activation in BxPC-3, but enhanced ERK1/2 activation in PANC-1 cells that express IGFBP-5. When MEK1/2 was blocked, Akt activation remained elevated in IGFBP-5 expressing PaC cells; however, inhibition of PI3K or MEK1/2 abrogated IGFBP-5-mediated cell survival.CONCLUSION: These results indicate that IGFBP-5 expression affects the cell cycle and survival signal pathways and thus it may be an important mediator of PaC cell growth.Sarah K Johnson Randy S Haun 2009World Journal of Gastroenterology2009,15,27:5
