Medical management of Crohn's disease: A guide for radiologists

The choice of therapies for Crohn's disease has expanded greatly over the past 30 years. Increasingly it is important that we attempt to identify subgroups of patients who will benefit most from each type of therapy. This article reviews the therapeutic options currently available, organized by the goal the practitioner hopes to achieve. Imaging is one critical way of aiding the classification of Crohn's disease by attempting to accurately determine the location, extent and, most importantly, the nature of the disease.     

When the standards aren't standard: Evidence-based medicine in the Russian context

This paper examines the uses of evidence-based medicine (EBM) in post-Soviet Russia through the use of semi-structured interviews. It asks what it means to talk about practicing evidence-based medicine in a setting where the context of practice presents considerable barriers to the implementation of EBM principles. Drawing on interviews with Russian physicians, medical students and users of the healthcare system, the paper argues that in post-Soviet Russia EBM serves as a strategic discourse for segments of the medical profession. With the collapse of the U.S.S.R. the healthcare system has been going through a period of crisis, and Russian physicians are finding that they have to redefine their professional identity with respect to the domestic and the international context and have to seek new sources for legitimating their professional position. The western origins of EBM endow this rhetoric with considerable power in the Russian context and render it a very useful tool in the project of redefinition.

静脉性脑梗死动物模型的建立及相关研究

静脉性脑梗死动物模型的建立是通过不同的栓塞方法闭塞实验动物上矢状窦的不同部位，其目的是观察脑组织的血流量、血氧饱和度、脑组织水含量、脑灌注压、及各种影像学表现等参数指标的变化，从病理生理角度探讨静脉性脑梗死的发病机理及演变过程。     

自律:在医患关系中的定位

医疗行为的特殊性，决定了医患双方在医学信息方面的不对称性和医者拥有一定的自由裁量权，因此，医者作为医疗服务的主体，如何增强自律意识，直接关系到诚信的树立及和谐的互动式医患关系的建立和发展。     

17β-雌二醇对子宫内膜异位症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响

目的研究17β-雌二醇(17β-E2)对子宫内膜异位症(内异症)患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响,探讨Wnt/β-catenin信号通路在介导雌激素促进内异症发生发展的作用。方法体外分离培养内异症患者在位子宫内膜间质细胞。用不同浓度17β-E2处理子宫内膜间质细胞48 h;此后选用10-10mol/L 17β-E2处理子宫内膜间质细胞12、24和48 h,逆转录聚合酶链反应(RT-PCR)和免疫印迹法(Western blotting)检测17β-E2处理前后子宫内膜间质细胞β-catenin mRNA和蛋白的表达水平。同法分析雌激素受体拮抗剂ICI182,780(10-6mol/L)对17β-E2促进β-catenin mRNA和蛋白表达的影响。免疫组织化学染色观察17β-E2作用后β-catenin在子宫内膜间质细胞中的定位。结果17β-E2能明显促进内异症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白的表达,并呈剂量和时间依赖性,于10-10mol/L作用48 h最明显。雌激素受体拮抗剂ICI182,780能明显抑制17β-E2对子宫内膜间质细胞β-catenin mRNA和蛋白的表达。免疫组织化学染色发现17β-E2能促进β-catenin在子宫内膜间质细胞核内的表达。结论雌激素可能通过激活Wnt/β-catenin信号通路促进内异症在位子宫内膜的异位种植。

The Application of Number Needed to Treat (NNT) to Clinical Problems in Radiotherapy

The goals of this report are: 1) to review the number needed to treat (NNT) concept, which, although well established in many sectors of medicine, is still relatively new to the radiotherapy community; 2) to discuss several clinical radiotherapy examples illustrating the inherent advantages of the NNT approach; and 3) to discuss potential future roles of the NNT concept within radiotherapy.
