Sudden Death Caused by Rupture of Spontaneous Ductus Arteriosus Aneurysm in an Adult

A 55-year-old man complained of sudden onset of severe neck pain. This was followed by prompt loss of consciousness and death. Autopsy revealed rupture of a saccular aneurysm, which was considered to have resulted from enlargement of the remaining ductal tissue, and was located on the medial aspect of the uppermost portion of the descending aorta. Dense blood extravasation was noted in the posterior mediastinum and extending to the strap muscles of the neck and larynx. Histological examination of the rupture site revealed disappearance of the medial elastic fibers and thickened intima covered with dense fibrous tissue. Spontaneous ductus arteriosus aneurysm in adults is a rare finding, but widespread use of imaging technologies has revealed that it develops more frequently than previously recognized. Fatal complications may occur even when the aneurysm is relatively small. Therefore, pathologists should be aware of this aneurysm as a potential cause of sudden death.     

'Brazil Needs to Change': Change as Iteration and the Iteration of Change in Brazil's 2002 Presidential Election1

Luiz Inácio Lula da Silva's triumph in Brazil's 2002 presidential election was construed in terms of a promise of radical change against the holders of the status quo . This article argues that in fact a more subtle political game was a stake in the election, a contest over the meaning and limits of change itself. The article examines how the various players – Lula da Silva, outgoing president Fernando Henrique Cardoso and the PSDB's presidential candidate José Serra – invoked and iterated a discourse of change to define and redefine the political dividing lines that marked out the electoral dispute and attempted to set or fix the distinctions between their political positions.

钝性暴力致脾破裂的发生机制研究

脾破裂与外伤之间因果关系的判断是法医学鉴定中一个十分常见但又非常棘手的问题。探究脾破裂的机制是解决上述问题的必要的理论基础。本文收集了２５例钝性暴力致脾破裂的案例，对脾破裂的部位与暴力打击部位及方向的关系进行了分析、整理，探讨了人体各部位遭受暴力作用后脾破裂的特点，及钝性暴力导致脾破裂的机制，发现脾破裂的机制主要包括直接暴力冲击以及脾脏在受外力作用后撞击胃、隔肌、脊柱、肋骨和胸后壁等两类，并指出对脾破裂机制的进一步研究将成为法医学鉴定研究工作中的一项重要课题。     

Cardiac Injuries Caused by Blunt Trauma: An Autopsy Based Assessment of the Injury Pattern

Abstract:  Nonpenetrating chest trauma with injury to the heart and aorta has become increasingly common, particularly as a result of rapid deceleration in high-speed vehicular accidents, over the past 2–3 decades. The high mortality rate of cardiac injuries and possible late onset complications make blunt cardiac injuries an important challenging point for legal medicine. One hundred and ninety cases with blunt cardiac injuries in a period of 3 years were analyzed retrospectively in terms of patterns of cardiac injury, survival times, and demographic profiles of the cases in this study.     

Myocardial Bridging: A Meta‐Analysis of Prevalence

The main objective of this article was to analyze prevalence data about myocardial bridging (MB) in published studies. To this purpose, we performed a meta‐analysis of studies published in English literature that contained data about the prevalence of MB and its anatomical characteristics. The overall prevalence was 19% (CI: 17–21%); autopsy studies revealed an overall prevalence of 42% (CI: 30–55%), CT studies 22% (CI: 18–25%), and coronary angiography 6% (CI: 5–8%). Most bridges were located on the left anterior descending artery (82% overall, 63% on autopsy studies), had a mean thickness of 2.47 mm and a mean length of 19.3 mm. In conclusion, autopsy studies should be the gold standard in evaluating the actual prevalence of myocardial bridges, while in vivo high‐resolution CT scanning should be preferred to coronary angiography studies.     

我国网络自制剧发展的现状及对策

互联网时代的到来,为网络自制剧的产生和发展准备了技术条件和受众基础,在视频网站和政策引导等多重因素推动下,网络自制剧成为了一种将与传统电视剧相抗衡的新兴文化形态.2014年各大视频网站纷纷投入巨资加入到网络自制剧的制作中来,被称为网络自制剧元年.网络自制剧具有制作成本低、周期短、制播合一、题材多元、内容贴近生活、交互性强等特点,深受年轻网民的喜欢.网络自制剧的发展有得天独厚的优势,也存在诸如质量低、格调低俗、同质化严重、盈利模式有待拓展等问题.要实现网络自制剧的健康发展还需要在内容、盈利模式、产业链条等多方面进行探索.     

柴胡疏肝散对体外静脉收缩的作用及其机制研究

目的 观察柴胡疏肝散对体外静脉环的收缩作用,探讨其作用机制。方法 选取人曲张大隐静脉及脐静脉血管环,采用微血管张力测定技术,以5-羟色胺、乙酰胆碱检测血管环内皮功能。依次由低至高加入不同浓度的柴胡疏肝散,测定曲张大隐静脉及脐静脉张力变化。用L-钙通道阻滞剂硝苯地平预处理后,测定不同浓度的柴胡疏肝散作用下曲张大隐静脉张力变化。结果 地奥司明对体外静脉无明显收缩作用;柴胡疏肝散能直接引起体外曲张大隐静脉及脐静脉收缩,呈一定剂量依赖性,其中脐静脉收缩幅度更大;硝苯地平可抑制柴胡疏肝散对体外曲张大隐静脉的收缩作用。结论 柴胡疏肝散能收缩体外静脉,其机制与促进细胞外钙内流有关。     

“9/11 is alive and well” or how critical terrorism studies has sustained the 9/11 narrative

ABSTRACT

This article argues that despite engaging in a powerful critique of the construction of the attacks of 11 September 2001 (or “9/11”) as temporal break, critical terrorism scholars have sustained and reproduced this same construction of “9/11”. Through a systematic analysis of the research articles published in Critical Studies on Terrorism, this article illustrates how critical scholars have overall failed to extricate themselves from this dominant narrative, as they inhabit the same visual, emotional and professional landscape as those they critique. After examining how CTS has reproduced but also renegotiated this narrative, the article concludes with what Michel Foucault would describe as an “effective history” of the attacks – in this case, a personal narrative of how the attacks did not constitute a moment of personal rupture but nonetheless later became a backdrop to justify my scholarship and career. It ends with a renewal of Maya Zeyfuss’ call to forget “9/11”.     

Fatal postpartum spontaneous liver rupture: case report and literature review

Maternal hepatic rupture is a rare complication of pregnancy that can be fatal to both mother and child. This phenomenon is most often associated with preeclampsia/eclampsia and/or HELLP syndrome, which is defined by a collection of clinical features including hemolysis (H), elevated liver enzymes (EL), and a low platelet count (LP). These disease processes are typically identified and treated during pregnancy, often in the last trimester. The described case is unusual in that the decedent had no known history of preeclampsia/eclampsia or HELLP syndrome during this pregnancy, and she died suddenly several days postpartum of liver rupture with massive intraperitoneal hemorrhage following a routine cesarean section delivery and an uneventful hospital course. Similar cases are infrequent in the literature, which is reviewed in this report.
