1得与失:苦苣苔科新的属级界定与分类系统——中国该科植物之变迁(英文)显示文摘过去20年对苦苣苔科植物的分子系统学研究已经极大地拓展了对这个科的种间关系与属一级之界定的理解。该文提供了一个苦苣苔科植物新分类系统,与传统的经典形态学分类系统比较,这一新系统被认为能更好地反映科下分类单元彼此之间的自然关系。众多传统意义上的属被分割、合并或者重新定义,这些巨大的分类变动正在影响着中国的苦苣苔科植物系统分类。此外,基于最近采集的材料,一些新属得以建立,一方面说明在中国还有相当多的野外工作需要做;而另一方面则再次证明了中国的苦苣苔科植物多样性是如此之丰富。在此,针对目前已经完成的工作和分类结论,对中国苦苣苔科植物的新分类系统进行了总结与概述,并深入地讨论了部分传统分类学上存在困惑的疑难属。MOLLER Michael 韦毅刚 温放 CLARK John L.

2Passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts and assessment of clinical outcomes显示文摘AIM To assess for passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts(TIPS) and compare outcomes with maximally dilated TIPS.METHODS Polytetrafluoroethylene covered TIPS(Viatorr) from July 2002 to December 2013 were retrospectively reviewed at two hospitals in a single institution. Two hundred and thirty patients had TIPS maximally dilated to 10 mm(m TIPS), while 43 patients who were at increased risk for hepatic encephalopathy(HE), based on clinical evaluation or low pre-TIPS portosystemic gradient(PSG), had 10 mm TIPS sub-maximally dilated to 8 mm(sm TIPS). Group characteristics(age, gender, Model for End-Stage Liver Disease score, post-TIPS PSG and clinical outcomes were compared between groups, including clinical success(ascites or varices), primary patency,primary assisted patency, and severe post-TIPS HE. A subset of fourteen patients with sm TIPS underwent follow-up computed tomography imaging after TIPS creation, and were grouped based on time of imaging(< 6 mo and > 6 mo). Change in diameter and crosssectional area were measured with 3D imaging software to evaluate for passive expansion.RESULTS Patient characteristics were similar between the sm TIPS and m TIPS groups, except for pre-TIPS portosystemic gradient, which was lower in the sm TIPS group(19.4 mm Hg ± 6.8 vs 22.4 mm Hg ± 7.1, P = 0.01). Primary patency and primary assisted patency between sm TIPS and m TIPS was not significantly different(P = 0.64 and 0.55, respectively). Four of the 55 patients(7%) with sm TIPS required TIPS reduction for severe refractory HE, while this occurred in 6 of the 218 patients(3%) with m TIPS(P = 0.12). For the 14 patients with follow-up computed tomography(CT) imaging, the median imaging follow-up was 373 d. There was an increase in median TIPS diameter, median percent diameter change, median area, and median percent area change in patients with CT follow-up greater than 6 mo after TIPS placement compared to follow-up within 6 mo(8.45 mm, 5.58%, 56.04 mm^2, and 11.48%, respectively, P = 0.01).CONCLUSION Passive expansion of sm TIPS does occur but clinical outcomes of sm TIPS and m TIPS were similar. Sub-maximal dilation can prevent complications related to overshunting in select patients.Michael C Hsu Charles N Weber S William Stavropoulos Timothy W Clark Scott O Trerotola Richard D Shlansky Goldberg Michael C Soulen Gregory J Nadolski 2017World Journal of Hepatology2017,9,12:11
3一侧大脑的局灶性梗塞后2~3周ADL情况显示文摘一侧大脑的局灶性梗塞可造成日常生活活动(Activities of Daily Living,ADL)的障碍,为了了解其障碍规律,以便有效地指导这类患者的ADL评价和训练,进一步探讨脑的运动控制功能与ADL的关系,选取了左右侧大脑中动脉梗塞引起的局灶性中等度脑梗塞患者各14例,于梗塞后2~3周用澳大利亚ADL指数对ADL的17项活动分三级进行了评价。结果从各项活动评分分析,大小便控制力、开关水龙头、刷牙、化妆、进食等五项活动基本上无异常改变,而室内移动、室外移动,上楼梯、下楼梯、从地到床的移动等五项活动有2级以上(包括2级)的改变。这可能与脑梗塞后所处的恢复过程的时相与运动形式的异常有关。戴红 Dennis.
