抑制炎症因素在他汀类药物心血管疾病多效性中的作用

他汀类药物自1976年上市应用于临床治疗以来,其非调脂作用,即他汀类药物的多效性近些年来越来越引起人们的重视,尤其是抑制炎症因素方面。随着近些年来研究的不断深入,越来越多的证据表明C反应蛋白作为体内最敏感的炎性标志物之一参与了多种临床常见心血管疾病的发生发展过程。而他汀类药物随着REVERSAL、PROVEIT、MIR...

探讨进展性缺血性脑卒中(SIP)的相关危险因素.选择德州市人民医院1999年～2009年163例SIP患者,首先对18个变量行单因素分析,然后对阳性变量行多因素Logistic逐步回归分析,筛选SIP发生的相关危险因素.高血压史、感染、加拿大卒中量表(CNS)评分、高血糖、TG、纤维蛋白原、脑水肿、颈动脉粥样硬化性狭窄、同型半胱氨酸和D-二聚体10个变量与SIP发生显著相关(P<0.05);脑水肿、颈动脉粥样硬化性狭窄、高血糖、感染、高纤维蛋白原水平和同型半胱氨酸6个因素是SIP发生的危险因素.脑水肿、颈动脉粥样硬化性狭窄,高血糖、感染、高纤维蛋白原在SIP发生中具有重要作用,为临床治疗提供了理论依据.     

Emotional reactions to scandals: When does moral character make a difference?

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality.     

背景音乐的节奏与歌词语言熟悉程度对驾驶行为和眼动的影响

摘要：采用3D模拟驾驶情景结合眼动技术探讨音乐节奏和歌词语言熟悉程度对驾驶行为和眼动规律的影响,研究结果表明：（1）驾驶经验对驾驶行为及眼动影响显著,新手与老手相比速度更慢、错误数更多;（2）音乐节奏对驾驶速度、眼跳和垂直搜索广度影响显著,快节奏与慢节奏相比,驾驶速度更快、平均眼跳距离更短、垂直搜索广度更短;（3）歌词语言熟悉程度对驾驶速度、错误数和平均注视时间影响显著,熟悉语言与陌生语言相比,驾驶速度更慢、错误数更多、平均注视时间新手更长,老手无影响。（4）节奏与语言共同影响驾驶过程中的水平搜索广度,陌生语言时快节奏的水平搜索广度高于慢节奏,熟悉语言时快节奏的水平搜索广度低于慢节奏。通过本实验,建议驾驶员在选择音乐时选择陌生语言歌词的音乐,音乐节奏则可视情况而定。     

Virtual/real transfer of spatial knowledge: benefit from visual fidelity provided in a virtual environment and impact of active navigation

The purpose of this study was to evaluate the effect the visual fidelity of a virtual environment (VE) (undetailed vs. detailed) has on the transfer of spatial knowledge based on the navigation mode (passive vs. active) for three different spatial recall tasks (wayfinding, sketch mapping, and picture sorting). Sixty-four subjects (32 men and 32 women) participated in the experiment. Spatial learning was evaluated by these three tasks in the context of the Bordeaux district. In the wayfinding task, the results indicated that the detailed VE helped subjects to transfer their spatial knowledge from the VE to the real world, irrespective of the navigation mode. In the sketch-mapping task, the detailed VE increased performances compared to the undetailed VE condition, and allowed subjects to benefit from the active navigation. In the sorting task, performances were better in the detailed VE; however, in the undetailed version of the VE, active learning either did not help the subjects or it even deteriorated their performances. These results are discussed in terms of appropriate perceptive-motor and/or spatial representations for each spatial recall task.     

"道物无际"--道教生态哲学纲要

道教生态哲学的基础围绕着道教的最高理念"道"及最基本范畴"物"生"神"而展开."道"作为道教信仰的终极理念,具有至高无上的地位,它与其它宗教或思想体系中的最高理念,如上帝、安那、梵(印度教吠檀多派)、绝对精神、自由意志等等范畴一样处于核心的地位,虽然这些范畴在解释一切精神和存在现象的作用上不尽相同.在道教哲学中,"道"是无所不覆、自生自化、永恒存在、派生万物的形而上的宇宙本体,是贯穿于整个自然界、人世间和神仙世界之中的最高理念.除了作为最高理念的"道"外,"物"生"和"神"也是道教生态哲学的最基本范畴."物"是对物质、万物、实物、器物、财物等具体事物的抽象,主要指有形的、变化的、局部的、杂多的现象存在."生"是对生命、身体、人生、生物、生物圈、生态环境的抽象,也包括事物的有机活动和转化的功能,如事物的生成、生长和生化."神"是对精神、神仙、神明的抽象,它是对"物"和"生"的提升、超越.道教将"道"贯穿于"物"生"神"三界,具体演化为自然界(物)、人世间(生)和神仙界(神),或物质世界、生命世界和神仙世界."物"生"神"的相互关系及其与"道"的关系构成了道教生态哲学的基础.     

Oculomanual Coordination in Tracking of Pseudorandom Target Motion Stimuli

Oculomanual coordination was investigated in 9 healthy subjects during tracking of pseudorandom motion stimuli. Each subject was required to track visual stimuli under eye-hand (EH) and eye-alone (EA) conditions. Subjects were exposed to 3 types of mixed sinusoidal stimulus with varying frequency or amplitude of the highest frequency component, or various degrees of irregularity. Progressive degradation in tracking performance was nonlinearly induced by an increase in either (a) the highest frequency component or (b) its amplitude, but not by stimulus irregularity. No significant difference was found in eye velocity gain and phase under the EH and EA conditions. Eye and hand responses were found to be highly correlated in gain and phase when compared across frequencies and motion stimuli. The results suggest that frequency and amplitude are dominant factors controlling the breakdown of oculomanual performance in response to pseudorandom stimuli. Frequency responses of smooth pursuit eye movements are not affected by the hand motion in pursuit of unpredictable stimuli. Eye and hand motor systems appear to share common nonlinear drive mechanisms when pursuing pseudorandom target motion stimuli.     

不确定性风险选择的抱负水平—相对效用整合理论

本文认为不确定性风险决策备择方案的选择标准既不是规范效用理论所主张的效用最大化,也不只是研究者们基于西蒙有限理性决策理论而提出的抱负水平,而是存在于决策不同阶段上的、由启发式策略控制着的这两种标准的整合,我们称之为抱负水平－相对效用整合标准。为此,我们在研究抱负水平结构的基础上提出了负险选择的抱负水平－相对效用整合理论及其支持性研究证据,并就有关问题进行了讨论与思考。指出抱负水平－相对效用整合是风
