青年颈心综合征避免误诊为冠心病的临床诊疗策略

通过对临床收集的187例青年(≤45岁)颈心综合征患者的临床资料进行分析。探讨青年颈心综合征临床误诊为冠心病的原因及避免误诊的诊疗策略。目的在于帮助临床医师对青年颈心综合征进行识别,注意如何与冠心病心绞痛相鉴别,对防止病情延误,尽早明确诊断积极治疗,排除冠心病,减少诊疗费用及避免冠脉造影的风险意义很大。     

慢性房颤导管消融策略的原则和个体化治疗

目前,慢性房颤导管消融的成功率及复发率均不尽人意。由于缺乏统一术式,慢性房颤消融采用的是肺静脉隔离、电图靶向消融及线性消融等多术式综合策略。在房颤消融策略上,既要坚持肺静脉电隔离原则,又要体现消融术式选择和实施的个体化,阶梯消融综合术式的推出就是这种思维方法的具体运用。     

A Case of Synaesthesia

Two experiments employed Potential Performance Theory (PPT) to correct for inconsistency in a speeded task. In Experiment 1, a search task was employed whereby participants searched for a target letter among distracters. In Experiment 2, the search task was more complex and naturalistic—participants searched for enemy weapons in aerial photographs. Not surprisingly, the results revealed that longer search times led to greater accuracy. However, this improvement was due only in part to improved search strategies. Much, if not most, of the improvement was due to increased consistency. The authors demonstrate and discuss some of the advantages to be gained by considering a speeded task within the context of a clear and mathematically precise theory (PPT).     

Ageing and attentional control

The research examines the structural bottleneck account and the resource account of the substantial dual-task deficits among older adults. Procedures from two common dual-task methodologies—the psychological refractory period and the relative-priority manipulation—were used to encourage maximization of the joint performance. Performance and time-sharing strategies from subjects between the ages of 20 and 70 years were examined. Age-related declines in time-sharing efficiency and in the precision of the executive control process were observed. The age-related effect was larger when two manual responses were required than when one manual and one vocal response were required, but no evidence for obligatory sequential processing was found. Except for the most demanding conditions, comparable practice effects were observed between the younger and older subjects, suggesting considerable cognitive plasticity in the older subjects. Implications for the two attentional accounts were discussed.     

家庭环境类型与青少年亲子冲突解决的关系

以北京829名普通中学生为被试.探讨了家庭环境类型与亲子冲突解决的关系.结果表明: (1)高亲密度、高情感表达、低矛盾性的家庭在亲子冲突解决的关系目标上的得分显著高于其它类型家庭;低亲密度、低表达性、高矛盾性的家庭在权力、公平、自认和自主目标上的得分显著高于其它类型家庭. (2)高亲密度、高表达性、低矛盾性的家庭更多使用积极的冲突解决策略;低亲密度、低表达性、高矛盾性的家庭更多使用消极的冲突解决策略.说明不同家庭环境类型下的青少年亲子冲突解决有不同的特点.

纵横家的外交策略及其现代意义——古代外交和谐论

纵横家是先秦时期著名的智慧群体,也是当时列国外交活动的主体。他们的有的放矢、善抓机遇、国无常友亦无常敌的思想认识以及外交活动须以国力为本的外交策略对于当前国际社会之间的交往具有重要的参考价值和启迪意义。     

阿司匹林抵抗及对策

阿司匹林广泛应用于心血管事件的预防,减少了心血管事件的发生。阿司匹林通过不可逆地和脂肪酸环氧化酶结合,抑制血小板聚集的激动剂血栓素A2的合成,发挥抗血小板聚集作用。但也有一些患者服用阿司匹林过程中有的血小板聚集能力和临床缺血事件不能被抑制。阿司匹林抵抗通常是指阿司匹林治疗未能引起预期的生物学效应抑制血栓素的生物合成或未能预防血栓事件的现象。导致这种现象的确切原因较复杂,包括不适当应用药物的相互作用,剂量不足,环氧化酶-1基因的多态性,及非血小板依赖血栓形成途径等有关。临床医生应该了解这些导致阿司匹林抵抗的因素,规范阿司匹林的应用剂量,适当地联合应用其他药物治疗。     

精神疾病患者遭受社会歧视的现状及其原因与对策分析

社会对精神疾病患者的歧视由来已久,这种歧视广泛存在于不同的阶层与民族当中,且各有其特点。其对精神病患者及其家属带来的负面影响是显而易见而且是深刻的,这种影响涉及到了患者生活的各个方面。本文对各种歧视的特点及其深层次原因进行了初步分析和探讨,并对如何减少这种歧视进行了探讨。
