A 2.3 kJ mather type pulsed plasma focus device was used for the synthesis of a Tin/a-Si3n4 thin film at room temperature. The film was characterized using X-ray diffraction （XRD）, X-ray photoelectron spectroscopy （XPS）, scanning electron microscopy （SEM）, and atomic force microscopy （AFM）. The XRD pattern confirms the growth of polycrystalline Tin thin film. The XPS results indicate that the synthesized film is non-stoichiometric and contains titanium nitride, silicon nitride, and a phase of silicon oxy-nitride. The SEM and AFM results reveal that the surface of the synthesized film is quite smooth with 0.59 nm roughness （root-mean-square）.

为了探讨自动化情绪调节过程是否存在积极效应,本研究采用oddball范式来研究自动化情绪调节中的积极效应。31名被试(15名右利手老年人和16名右利手青年人)参加了本研究。实验中要求被试观察并按键判断呈现在视野中央的十字形注视点的形状变化。在注视点的左右两侧呈现情绪面孔卡通图,其中代表快乐和悲伤的情绪面孔卡通图作为偏差刺激,中性面孔卡通图作为标准刺激,共计54张。基于前人研究,我们分析了n170(170-250ms)成分,早期eMMn(170-250ms)和晚期eMMn(250-350ms)成分,并通过重复测量方差分析各自的峰值和平均波幅。行为结果表明老年组和青年组对呈现在视野中央的十字形注视点的形状变化判断的准确率没有显著的差异,交互作用也不显著(所有条件的90%以上,pn170。在青年人中,悲伤偏差刺激面孔比悲伤标准刺激面孔诱发了更大的n170,但是这种差异在老年人中不存在。悲伤面孔和快乐面孔诱发的eMMn成分在老年人中存在边缘显著的差异(p=0.062),在青年人中差异不显著。在青年人中,悲伤面孔比快乐面孔诱发了更大的晚期eMMn成分,而老年人中却呈现相反的结果。总体来说,本研究为自动化情绪调节中的积极效应提供了明确的支持证据。未来研究需要进一步探讨自动化情绪调节积极效应机制及其理论基础。

目的比较急性心肌梗死(AMI)病人再灌注后一段时间内的心肌水肿和相应区域的心肌收缩功能的关系。材料与方法本研究经地方伦理委员会批准,所有病人签署知情同意书。39例(男性34例,年龄35～73岁,平均57岁,)ST段抬高AMI病人在经皮冠状动脉介入治疗后的3个时间点行T2加权、标记和晚期钆增强MR成像。测量梗死区、梗死周围区以及远端心肌的环周缩短率、T2加权成像的信号强度和体积。根据梗死周围有无水肿对病人进行分层,梗死周围水肿定义为T2加权信号强度高于远端心肌的2个或更多标准偏差的区域。应用事后Bonferroni校正重复测量方差分析进行数据分析。结果在介入治疗后的3个时间点梗死周围水肿性心肌的收缩力较远端心肌降低,分别为2d(-0.137∶-0.226,P0.05)。梗死周围水肿性心肌在第30天(P=0.02)和第90天(P<0.01)时的收缩力有所改善,这体现在水肿体积的减小和信号强度的降低。收缩力的降低与水肿体积(r=0.30,P=0.01)和标准化的水肿信号强度相关(r=0.28,P<0.01)。在8例完全透壁性梗死病人中,梗死区收缩力在第2～90天之间有所改善(P=0.02)。结论梗死周围心肌收缩力随心肌水肿消退而有所改善。水肿体积和T2加权成像的信号强度与AMI再灌注后心肌功能恢复相关。

帕金森痴呆及Lewy体痴呆的视觉感知力

世界核心医学期刊文摘（眼科学分册） 2005年第5期1卷 7-7页

作者： Mosimann U.P. mather G. Wesnes K.A. 陈立军 Institute for A geing and Health Wolfson Research Centre Newcastle General Hospital Newcastle upon Tyne NE4 6BE United Kingdom Dr.

Objective: To quantify visual discrimination, spacem otion, and objectform perception in patients with Parkinson disease dementia (PDD), dementia with Lewy bodies (DLB), and Alzheimer disease (AD). Methods: Th e authors used a crosssectional study to compare three demented groups matched for overall dementia severity (PDD: n=24; DLB: n=20; AD: n=23) and two age, s ex, and educationmatched control groups (PD: n=24, normal controls [nC]: n =2 5). Results: Visual perception was globally more impaired in PDD than in nondeme nted controls (nC, PD), but was not different from DLB. Compared to AD, PDD pati ents tended to perform worse in all perceptual scores. Visual perception of pati ents with PDD/DLB and visual hallucinations was significantly worse than in pati ents without hallucinations. Conclusions: Parkinson disease dementia (PDD) is as sociated with profound visuoperceptual impairments similar to dementia with Lewy bodies (DLB) but different from Alzheimer disease. These findings are consisten t with previous neuroimaging studies reporting hypoactivity in cortical areas in volved in visual processing in PDD and DLB.
