Sociology Study 2013年第1期3卷 23-39页

作者： Ben Atkins nathan R. Moran Robert D. Hanser Midwestern State University US University of Louisiana at Monroe US

The United States Congress set a benchmark in US anti-human trafficking policy with the Trafficking Victims Protection Act of 2000 （TVPA 2000j. The TVPA 2000 and its subsequent reauthorizations in 2003, 2005, and 2008 were put forth to increase the scope, focus, and effectiveness of US efforts to combat human trafficking. In-depth analyses of each reauthorization provide an understanding of the aims of the TVPA. The evolution of the TVPA reauthorizations dearly demonstrates that the US is committed to thwarting human trafficking both domestically and internationally. The analyses examine strengths and weaknesses of the legislation and provide insight as to how the TVPA reached its current state as the William Wilberforce Trafficking Victims Protection Reauthorization Act of 2008 （TVPRA 2008）. Drawing from the evolution of TVPA legislation, the future of the human trafficking phenomenon and legislation is discussed.

World journal of Hepatology 2013年第3期5卷 133-136页

作者： Brett M Hymel David W Victor Luis Alvarez nathan j Shores Luis A Balart Department of Gastroenterology Louisiana State University School of Medicine Department of Gastroenterology and Hepatology Tulane University School of Medicine

A 26-year-old male presented with three weeks of jaundice after the self-initiation of the injectable anabolic steroid, Mastabol [Dromastanolone Di-Propionate (17 beta-Hydroxy-2alpha-methyl-5alpha-androstan-3one propionate)]. He reported dark urine, light stools, and pruritus. He denied abdominal pain, intravenous drug use, intranasal cocaine, blood transfusions, newly placed tattoos, or sexually transmitted diseases. He used alcohol sparingly. Physical exam revealed jaundice with deep scleral icterus. The liver was palpable 2 cm below the right costal margin with no ascites. The peak bilirubin was 23.6 mg/dL, alkaline phosphatase was 441 units/L, and aspartate aminotransferase/alanine aminotransferase were 70 units/L and 117 units/L respectively. A working diagnosis of acute intrahepatic cholestasis was made. Liver biopsy revealed a centrilobular insult with neutrophilic infiltrates and Ito cell hyperplasia consistent with acute drug induced cholestasis. The patient' s clinical symptoms resolved and his liver enzymes, bilirubin, and alkaline phosphatase normalized. Anabolic steroids with 17 alpha carbon substitutions have been associated with a bland variety of cholestatic injury with little hepatocellular injury. Cholestasis, under these circumstances, may be secondary to the binding of drugs to canalicular membrane transporters, accumulation of toxic bile acids from canalicular pump failure, or genetic defects in canalicular transport proteins. Mastabol is an injectable, 17 beta hydroxyl compound with no alpha alkyl groups at the 17 carbon position. As such, it has been reported to have little potential toxic effects on the liver. This is the first known reported case of Mastabolinduced cholestatic liver injury. It highlights the need for physicians to consider such widely available substances when faced with hepatic injury of unclear etiology.

2型糖尿病的流行给全世界的卫生保健工作带来了13益增长的巨大负担。估计到2025年，全世界2型糖尿病患者的数量将从2000年的1．51亿增加到3亿。严格控制血糖能够降低微血管并发症这一认识使得有效治疗高血糖成为优先考虑的因素。最近，控制糖尿病及其并发症试验（DCCT）显示，以血糖正常为目标的强化治疗对1型糖尿病患者的心血管疾病有益。对于2型糖尿病，来自英国糖尿病前瞻性研究（UKPDS）的流行病学资料表明降低血糖能减少心血管疾病的风险。

Open journal of Medical Imaging 2015年第2期5卷 66-70页

作者： Edwin A. Takahashi nathan C. Hull Christopher j. Stevens joseph M. Hoxworth Steven M. Weindling Christopher P. Wood Department of Radiology Mayo Clinic Rochester USA Department of Radiology Mayo Clinic Scottsdale USA Department of Radiology Mayo Clinic Jacksonville USA

Sinonasal schwannomas are rare, benign and slow-growing peripheral nerve sheath tumors without age, race, or gender predilection. We present the unusual case of a 59-year-old female who pre-sented with right-sided retro-orbital pressure and rhinorrhea. Radiographic imaging revealed a mass centered in the right superior nasal cavity with extension through the cribriform plate into the right more than the left subfrontal region. Biopsy confirmed the diagnosis of a sinonasal schwannoma, which was resected via nasal endoscopic surgery and ethmoidectomy. These tumors, albeit rare, should be considered in the differential diagnosis for patients presenting with a para-nasal sinus mass to ensure inclusion of this benign lesion and avoid unnecessary aggressive in-tervention.

长期以来,美国对外关系研究的新路径并没有对例外论者的假设构成挑战,同时也无法对全球范围内的美国经验提供一个比较视角。最近开展的边地(borderland)和边疆(frontier)研究则为历史学家提供了一个深入到文化遭遇、文化认同转变以及国家政治边缘的富有价值的视角,并可以对周边地区的人力和自然资源如何整合到更大的经济交换体系这一过程进行分析。在对边疆研究的域外经验与实践进行系统梳理之后,本文指出,有必要将边疆路径引入美国对外关系研究的领域,这样不仅有助于相关研究的推进,而且能够突破特纳理论的局限,进而更全面地看待包括当代跨国市场等在内的美国的内部发展与海外扩张历程。
