A pancreatic pseudocyst(PPC) is typically a complication of acute and chronic pancreatitis, trauma or pancreatic duct obstruction. The diagnosis of PPC can be made if an acute fluid collection persists for 4 to 6 wk and is enveloped by a distinct *** PPCs regress spontaneously and require no treatment, whereas some may persist and progress until complications occur. The decision whether to treat a patient who has a PPC, as well as when and with what treatment modalities, is a difficult one. PPCs can be treated with a variety of methods: percutaneous catheter drainage(PCD), endoscopic transpapillary or transmural drainage, laparoscopic surgery, or open pseudocystoenterostomy. The recent trend in the management of symptomatic PPC has moved toward less invasive approaches such as endoscopic- and image-guided PCD. The endoscopic approach is suitable because most PPCs lie adjacent to the stomach. The major advantage of the endoscopic approach is that it creates a permanent pseudocysto-gastric track with no spillage of pancreatic enzymes. However, given the drainage problems, the monitoring, catheter manipulation and the analysis of cystic content are very difficult or impossible to perform endoscopically, unlike in the PCD approach. Several conditions must be met to achieve the complete obliteration of the cyst *** duct anatomy is an important factor in the prognosis of the treatment outcome, and the recovery of disrupted pancreatic ducts is the main prognostic factor for successful treatment of PPC, regardless of the treatment method used. In this article, we review and evaluate the minimally invasive approaches in the management of PPCs.

Drug-induced liver injury: Do we know everything?

引用

World Journal of Hepatology 2017年第10期9卷 491-502页

作者： Tamara Alempijevic Simon zec Tomica Milosavljevic University of Belgrade School of Medicine Clinical Center of Serbia Clinic for Gastroenterology and Hepatology

Interest in drug-induced liver injury(DILI) has dramatically increased over the past decade, and it has become a hot topic for clinicians, academics, pharmaceutical companies and regulatory bodies. By investigating the current state of the art, the latest scientific findings, controversies, and guidelines, this review will attempt to answer the question: Do we know everything? Since the first descriptions of hepatotoxicity over 70 years ago, more than 1000 drugs have been identified to date, however, much of our knowledge of diagnostic and pathophysiologic principles remains unchanged. Clinically ranging from asymptomatic transaminitis and acute or chronic hepatitis, to acute liver failure, DILI remains a leading causes of emergent liver transplant. The consumption of unregulated herbal and dietary supplements has introduced new challenges in epidemiological assessment and clinician management. As such, numerous registries have been created, including the United States Drug-Induced Liver Injury Network, to further our understanding of all aspects of DILI. The launch of Liver Tox and other online hepatotoxicity resources has increased our awareness of DILI. In 2013, the first guidelines for the diagnosis and management of DILI, were offered by the Practice Parameters Committee of the American College of Gastroenterology, and along with the identification of risk factors and predictors of injury, novel mechanisms of injury, refined causality assessment tools, and targeted treatment options have come to define the current state of the art, however, gaps in our knowledge still undoubtedly remain.

As demands to maintain the global food production continue to mount,multinational seed companies are turning to new DNA marker technologies to accelerate the rate of plant breeding and crop *** key to widespread adoption of molecular breeding is the availability of flexible and cost-effective tools that can perform combinatorial and high-throughput genotyping of single-nucleotide polymorphisms(SNPs)to guide the crop development *** this end,we have developed a programmable,droplet-based microfluidic device for genotyping maize genomic DNA.A unique feature of the microfluidic platform is the nano sample processors(NSPs),which allow the device to sequentially load an unrestricted number of unique DNA samples using only two inlets,overcoming the current limitation to the number of sample inputs due to small device *** and programmable droplet generation within the device allows each sample to be genotyped against a panel of markers on ***,we have successfully implemented the Invader assay for SNP genotyping in flowing,50-nL droplets,thus achieving significant reduction in consumption of reagents per reaction as compared with conventional genotyping *** a demonstration,we performed 240 Invader reactions(testing 8 DNA samples against 10 SNP markers)and achieved greater than 93% accuracy in SNP calling of plant DNA samples in a single droplet-based experiment.

一直辩论下个世纪是否将是中国世纪。中国经济令人难以置信的转变已将中国变成世界经济的工厂。尽管中国的商业模式建立在廉价劳动力生产低质量产品的基础上,也是如此,在过去10年里,中国已被证明是能够发展高科技公司。这些公司有能力生产精密,复杂的计算机和生物技术仪器。大多数经济学家同意一个事实,在经济实力方面,中国将成为领导者。然而,没有中国的可口可乐,中国的耐克或中国的苹果就不会有中国的世纪。如果中国要继续增长,其制造商需要上移价值链,自己产品设计,提供配套服务,并投资品牌,以便能够使产品赚取更高的利润。消费电子行业是一个很好的起点。蓬勃发展的国际消费电子公司都有一些普遍的特点,其中之一是具有强大的品牌资产。一个全球性的品牌顾问公司Interbrand,每年都会确认100强的国际品牌。这个最强大的全球性品牌的名单上有甚至没有一个来自中国的品牌。尽管事实是,中国是最大的消费电子产品制造商,但是它还是没有许多强大的全球知名的品牌。因此,本研究的目的是确定变量,哪些是有助于Interbrand的公司形成强大的品牌资产,并解释中国的商业环境缺少这些因素的原因,为中国企业制定正确的可以遵循的战略。促进消费电子行业的强势品牌资产的因素可分为三大类：宏观经济,相关行业和消费者的因素。宏观经济因素是指该国的经济发展和成熟的知识产权法律的水平阶段。一旦政府提供为行业提供良好的条件,行业的相关因素,如研发,营销投资和组织结构开始起主导作用,在促进创新和创造力,进而建立一个强大的品牌。然而,一个品牌什么都不是如果它没有追随者,比如消费者。在中国的商业环境中,这些因素很多都不具备,由于种种原因,目前的对保护知识产权的执法不力,短视的CEO的领导,高度官僚的组织结构。然而,建设一个强大的品牌最重要的障碍是中国企业高管的心态：专注于短期利润,往往以至于忽略了长远的视角。所有证据表明,这将是中国世纪：显著的经济增长,开放的市场,成为最大的出口国,最大的制造商,成为最有活力的商业市场。但是,它正使得中国企业难以在国内竞争,更不用说在国外了。因此,为了在这个竞争激烈的舞台上,他们需要完成中国制造到中国创造的转变,并开始建立竞争优势,这将不依赖于任何低成本,但依赖于无形资产,如形象,信誉,品牌。

介绍了一种以商业纯铝箔为基体的多层复合材料的加工过程、组织结构和力学性能。采用热轧制交替排布的纯铝和阳极铝箔制备多层复合材料;此外,采用同样的工艺制备纯铝箔多层复合材料。在这两种情况下,均得到紧实致密的多层复合材料。为了研究复合材料的微观组织演变和力学性能,分别进行了光学和扫描电镜(SEM)、能谱(EDS)、X射线衍射(XRD)分析以及硬度、拉伸和三点弯曲试验。微观组织表征显示,阳极铝复合材料铝基体中平行分布着棒状Al_2O_3颗粒,而且铝箔界面间生成少量粗大颗粒。两种复合材料的硬度、强度、弹性模量和抗弯强度均高于纯铝材料的,而延展性明显降低。与纯铝箔多层复合材料相比,阳极铝箔多层复合材料具有较高的强度和弹性模量以及较低的延展性。材料的断裂失效方式与延展性的变化一致。
