哺乳动物肝内门管鞘系统的相似性和肝脏类型

作者通过对猪、牛、羊、马、驴、兔、狗、猕猴、梅花鹿等动物肝内门管鞘系统的观察 ,发现哺乳动物和人的门管鞘系统是相似的 ,全肝均可分为左、右二叶和左外侧段 ,左内侧段 ,右内侧段 ,右外侧段。作者认为哺乳动物肝脏在外形上的主要区别在于愈合程度不一 ,并可按愈合情况将哺乳动物肝分为多叶类型和全愈合类型。

一种基于ITK和VTK的肝脏管道自动分级算法

肝脏管道的分级是肝脏管道分支类型判定、管道变异情况分析的重要步骤,是针对性地制定个性化手术方案,从而降低肝切除手术风险的前提.基于ITK(insight segmentation and registration toolkit)和VTK(visualization toolkit)设计了一种肝脏管道自动分级的算法,实现了肝脏CT序列的管道自动提取、管道细化、管道拓扑建模以及管道分级的功能,最后用不同的颜色将不同级别的管道进行三维显示,便于医生更直观地对肝脏的管道系统的形态及结构进行分析,为制定术前手术计划提供帮助.

An annual topic highlight: Alcohol and liver, 2011

An annual topic highlight: Alcohol and Liver, 2011, covers the important and new aspects of pathogenesis of alcoholic liver diseases (ALD). It includes broad topics ranging from the exacerbation of ALD by infectious (viral) agents (hepatitis C virus and human immunodeficiency virus) to the influence of alcohol on liver fibrogenesis, lipid rafts, autophagy and other aspects. This issue is recommended for both basic scientists and clinicians who are involved in alcoholic liver research.
