Portal vein embolization for induction of selective hepatic hypertrophy prior to major hepatectomy: rationale,techniques, outcomes and future directions

引用

cancer Biology & Medicine 2016年第4期13卷 426-442页

作者： david Li david c.Madoff Department of Radiology Division of Interventional Radiology New York-Presbyterian Hospital Weill Cornell Medical Center

The ability to modulate the future liver remnant(FLR) is a key component of modern oncologic hepatobiliary surgery practice and has extended surgical candidacy for patients who may have been previously thought unable to survive liver resection. Multiple techniques have been developed to augment the FLR including portal vein embolization(PVE), associating liver partition and portal vein ligation(ALPPS), and the recently reported transhepatic liver venous deprivation(LVD). PVE is a well-established means to improve the safety of liver resection by redirecting blood flow to the FLR in an effort to selectively hypertrophy and ultimately improve functional reserve of the FLR. This article discusses the current practice of PVE with focus on summarizing the large number of published reports from which outcomes based practices have been developed. Both technical aspects of PVE including volumetry, approaches, and embolization agents; and clinical aspects of PVE including data supporting indications, and its role in conjunction with chemotherapy and transarterial embolization will be highlighted. PVE remains an important aspect of oncologic care; in large part due to the substantial foundation of information available demonstrating its clear clinical benefit for hepatic resection candidates with small anticipated FLRs.

近年来,创新网络作为区域和城市创新驱动力的重要性得到了广泛关注。一些研究将网络关系视为知识在城市内和城市间传播的渠道,并通过网络分析视角洞察城市创新的结构和动态。然而,城市创新的网络机制,特别是数字经济发展背景下的数字赋能城市创新能力提升机制还有待进一步研究。本文利用长三角城市群26个城市2009年—2018年联合申请专利数据构建了城市创新网络,探讨了网络结构属性——小世界和结构洞对城市创新能力的影响。结果表明,小世界与城市创新能力呈“倒U型”关系,数字经济发展水平正向调节了二者之间的“倒U型”关系,结构洞对城市创新能力具有正向影响。本文厘清了创新网络结构对城市创新能力的影响,回应了以往研究关于小世界和结构洞对创新影响的理论争议,为区域创新的理论研究提供了新颖性观点,深化了对城市群创新发展规律的认识,对推进中国城市群协同创新具有重要意义。

ANALYSIS OF LIQUID SLUG MOTION IN A VOIDED LINE

引用

Journal of Hydrodynamics 1993年第3期5卷 75-88页

作者： Yang, Jiandong Wigget, david c wuhan Univ of Hydraulic and Electric Engineering Wuhan China

A quasi two-dimensional two-phase flow cylinder model of slug motion in a voided line developed in this paper can predict reasonably the change of flow pattern of the slug, air entrainment, holdup and the distribution of axial velocity. However, if using the theory of transfer momentum to estimate the pressure-time history of slug at the elbow, the result of calculation is not good in agreement with that of experiment. Analysis of the experiment results and the estimations of using the theory of transient two-phase flow indicate that an evident water hammer response occurs in the slug, when the high-speed slug impacts on the elbow, and the peaks and waveform of pressure-time history are dependent mainly on the propagation of transient two-phase flow in the slug.

Ethical tensions in solid organ transplantation: The price of success

World Journal of Gastroenterology 2006年第20期12卷 3259-3264页

Solid organ transplantation has rapidly developed into the therapy a choice for end-stage organ failure. The expansion of its use has resulted is a large deficiency in organ supply. To address this, the field of organ transplantation has attempted to develop new strategies that would increase the availability of organs for transplant. Some of these strategies include expansion of the donor pool by increasing the number of living donors or using deceased donor organs that may be marginal or ＂expanded＂ The intent is to bring life-saving therapy to individuals in need; however, much of this expansion has been brought forward without clear prospective guidelines. This article focuses on the current disparity between organ supply and demand, and how this has impacted the use of living donors and development of the ＂expanded donor＂ concept.
