1世界卫生组织(WHO)造血与淋巴组织肿瘤分类方案:临床顾问委员会会议报告显示文摘引言 :从 1995年开始 ,欧洲病理学工作者协会和血液病理学会一直致力于制定一个新的世界卫生组织 (WHO)血液恶性肿瘤分类方案 ,该分类方案包括淋巴系肿瘤、髓系肿瘤、组织细胞肿瘤和肥大细胞肿瘤。 材料与方法 :此项 WHO计划共组成十个病理学工作者委员会 ,负责确定病种和作出定义。另外还成立一个由国际血液学家和肿瘤学家组成的临床顾问委员会 (CAC)以保证该分类的临床实用性。 1997年 11月召开会议讨论了与该分类有关的临床问题。 结果 :WHO采纳了 1994年国际淋巴瘤研究组 (IL SG)报告的修订欧美淋巴系肿瘤分类 (REAL)方案作为淋巴系肿瘤的分类方案。该方案的分类方法遵循以下原则 :分类应是联合应用形态学、免疫表型、遗传特征及临床特征能够清楚界定的“真实存在”(“real”)病种的名录 ,上述各项特征的相对重要性因病种不同而异 ,不存在任何“金标准”。 WHO将 REAL分类原则延用于髓系肿瘤和组织细胞肿瘤 ,髓系肿瘤的分类包括联合应用细胞形态学和细胞遗传学异常能够界定的各个病种。围绕一系列临床问题召集的这次 CAC会议 ,就提交的大多数问题达成共识 ,这些问题及共识将详述于下。对于另外一些问题 ,CAC认为淋巴系肿瘤临床分组既无必要也不必需 ,患者的治疗取决于淋巴瘤的具体类型 ,如有?N L Harris E S Jaffe J Diebold G Flandrin H K Muller-Hermelink J Vardiman T A Lister C D Bloomfield 张凤奎 郝玉书 2001白血病.淋巴瘤2001,10,3:20
2针对患者利益的机器学习和人工智能研究:在透明性、可重复性、伦理和有效性等方面的20个关键问题显示文摘机器学习(ML)、人工智能(AI)和其他现代统计方法正为利用先前尚未开发且极速增长的数据资源提供新的机会,以期让患者获益。尽管目前正在进行许多有前景的研究,特别是在图像方面,但就文献整体而言还缺乏透明度、对可重复性清晰的阐述、对潜在伦理问题的探究,以及对有效性的明确验证。这些问题的存在有许多原因,其中最重要的一点(为此我们提供了初步解决方案)就是当前缺乏针对ML和AI的最佳实践指南。我们认为从事研究的跨学科团队和应用ML/AI影响健康的项目,将因解决有关透明度、可重复性、伦理和有效性(TREE)的一系列问题而受益。这里提出的20个关键问题为研究团队提供了一个研究设计、实施和报告框架;帮助编辑和同行评审专家评估文献的贡献;让患者、临床医生和政策制定者评估新发现可能会给患者带来的获益。Sebastian Vollmer Bilal A Mateen Gergo Bohner Franz J Kirdly Rayid Ghani Pall Jonsson Sarah Cumbers Adrian Jonas Katherine S L McAllister Puja Myles David Granger Mark Birse Richard Branson Karel G M Moons Gary S Collins John P A Chris Holmes Harry Hemingwayp 李峰(译) 徐磊(校) 赵邑(校) 2020英国医学杂志中文版2020,23,9:5
3Plecanatide-mediated activation of guanylate cyclase-C suppresses inflammation-induced colorectal carcinogenesis in Apc+/Min-FCCC mice显示文摘AIM To evaluate the effect of orally administered plecanatide on colorectal dysplasia in Apc^(+/Min-FCCC) mice with dextran sodium sulfate(DSS)-induced inflammation. METHODS Inflammation driven colorectal carcinogenesis was induced in Apc^(+/Min-FCCC) mice by administering DSS in their drinking water. Mice were fed a diet supplemented with plecanatide(0-20 ppm) and its effect on the multiplicity of histopathologically confirmed polypoid,flat and indeterminate dysplasia was evaluated. Plecanatide-mediated activation of guanylate cyclase-C(GC-C) signaling was assessed in colon tissues by measuring cyclic guanosine monophosphate(cG MP) by ELISA, protein kinase G-II and vasodilator stimulated phosphoprotein by immunoblotting. Ki-67, c-myc and cyclin D1 were used as markers of proliferation. Cellular levels and localization of b-catenin in colon tissues were assessed by immunoblotting and immunohistochemistry, respectively. Uroguanylin(UG) and GC-C transcript levels were measured by quantitative reverse transcription polymerase chain reaction(RT-PCR). A mouse cytokine array panel was used to detect cytokines in the supernatant of colon explant cultures. RESULTS Oral treatment of Apc^(+/Min-FCCC) mice with plecanatide produced a statistically significant reduction in the formation of inflammation-driven polypoid, flat and indeterminate dysplasias. This anti-carcinogenic activity of plecanatide was accompanied by activation of cG MP/GC-C signaling mediated inhibition of Wnt/b-catenin signaling and reduced proliferation. Plecanatide also decreased secretion of pro-inflammatory cytokines(IL-6, IL-1 TNF), chemokines(MIP-1, IP-10) and growth factors(GCSF and GMCSF) from colon explants derived from mice with acute DSS-induced inflammation. The effect of plecanatidemediated inhibition of inflammation/dysplasia on endogenous expression of UG and GC-C transcripts was measured in intestinal tissues. Although GC-C expression was not altered appreciably, a statistically significant increase in the level of UG transcripts was detected in the proximal small intestine and colon, potentially due to a reduction in intestinal inflammation and/or neoplasia. Taken together, these results suggest that reductions in endogenous UG, accompanied by dysregulation in GC-C signaling, may be an early event in inflammation-promoted colorectal neoplasia; an event that can potentially be ameliorated by prophylactic intervention with plecanatide.CONCLUSION This study provides the first evidence that orally administered plecanatide reduces the multiplicity of inflammation-driven colonic dysplasia in mice, demonstrating the utility for developing GC-C agonists as chemopreventive agents.Wen-Chi L Chang Shet Masih Anusha Thadi Viren Patwa Apoorva Joshi Harry S Cooper Vaseem A Palejwala Margie L Clapper Kunwar Shailubhai 2017World Journal of Gastrointestinal Pharmacology and Therapeutics2017,8,1:5
