非ST段抬高急性冠脉综合征药物治疗规范化分析

回顾性分析我院收治的129例非ST段抬高急性冠脉综合征患者的临床资料.对比在非ST段抬高急性冠脉综合征诊治上与最新指南的差距,找出改进措施.结果表明我院的临床实践与最新指南存在较大差距,在强化抗栓,调脂治疗,β受体阻滞剂及血管紧张素转换酶抑制剂类药物使用上均有待提高.今后应采取更加积极的措施,规范用药,以达到更好的预后和转归效果.     

非ST段抬高急性冠脉综合征的危险分层和个体化治疗

冠心病是我国居民致残、致死的重要原因之一,冠心病的主要死因是急性冠脉综合征.急性冠脉综合征是一系列病因相同,但病情严重程度、治疗方法和预后差别很大的疾病谱.对非ST段抬高急性冠脉综合征进行危险分层和个体化治疗已成为共识.本文对最近发表的中华心血管病学会非ST段抬高急性冠脉综合征诊治指南,并结合欧洲心脏病学会、美国心脏病学会指南进行解读.     

急诊PCI术前大剂量瑞舒伐他汀治疗对冠状动脉血流的影响

探讨PCI术前给予大剂量瑞舒伐他汀对急性ST段抬高型心肌梗死患者冠脉血流的影响.入选2010年1月至2011年6月因急性ST段抬高型心肌梗死于大连医科大学附属第二医院行急诊PCI术的患者120例.随机分为试验组,即术前给予瑞舒伐他汀20mg口服,及对照组,即术前不给予瑞舒伐他汀口服.通过TIMI帧数法比较冠脉血流情况.结果两组患者临床特点、罪犯血管、疼痛到球囊扩张时间、多支病变比例、支架类型及大小均无统计学差异.术后TIMI3级血流的比例虽无统计学差异,但试验组比对照组有增加趋势(93.5％比89.7％).PCI术后试验组与对照组相比校正TI-MI帧数明显减低(26.2±11.52比34.3士18.11),数据比较有统计学差异.急诊PCI术前给予大剂量瑞舒伐他汀对于改善急性ST段抬高型心肌梗死患者术后的冠状动脉血流是有益的.

导言:冠心病的抗血小板治疗越来越重要

正众所周知,各种类型冠心病的发病、并发症的发生以及动脉硬化的进展过程都有血小板的参与,因此冠心病的抗血小板治疗已成为冠心病尤其是急性冠脉综合征治疗的基石,抗血小板治疗的重点应是急性冠脉综合征的患者[不稳定型心绞痛(UA);非ST段抬高型心肌梗死(NSTEMI);ST段抬高型心肌梗死(STEMI)]、经皮冠状动脉介入治疗(PCI)围手术期治疗、STEMI溶栓治疗的辅助治疗、冠状动脉旁路移植术(CABG)术后的治疗结合个体参照     

急性ST段抬高型心肌梗死再灌注治疗的急缓之择

急性ST段抬高型心肌梗死(STEMI)最有效治疗方法是再灌注治疗,主要包括直接经皮冠状动脉介入治疗(PCI)和溶栓治疗.只有结合患者、医疗机构的实际情况,合理选择再灌注治疗方案,才能使STEMI患者获益最大化,改善其长期预后.     

急性冠脉综合征如何进行抗血小板治疗

急性冠脉综合征(acute coronary syndrome,ACS)是以冠状动脉粥样硬化斑块破裂或侵袭,继发完全或不完全闭塞性血栓形成为病理基础的一组临床综合征,包括急性ST段抬高型心肌梗死、急性非ST段抬高型心肌梗死和不稳定型心绞痛(UA)。血栓形成是ACS发病的病理基础。ACS的发病机制为长期冠脉血管内皮功能障碍及炎症反应导致斑块形成,急性发作期表现为斑块破裂或侵蚀,导致血小板聚集并形成血栓从而引起心肌细胞损伤。ACS在全球的发病率和死亡率高,无论在发达国家还是发展中国家,ACS都是导致死亡的重要原因之一。目前冠心病仍是人类,尤其是高龄患者致死的最主要原因,同时中青年人群中其发病率及死亡率也呈急剧上升趋势。针对急性冠脉综合征治疗,无论选择保守药物治疗还是选择PCI开通血管使心肌充分再灌注治疗,均以抗血小板聚集治疗为治疗基石。     

围手术期负荷剂量他汀对急性ST段抬高型心肌梗死患者预后的影响

为了探讨围手术期给予阿托伐他汀负荷剂量对急性ST段抬高型心肌梗死（STEMI）患者急诊经皮冠状动脉介入治疗（PCI）后对心血管事件的影响。选取因STEMI行急诊PCI术患者160例,其中80例于PCI术前给予阿托伐他汀负荷剂量40mg,80例术前未给予阿托伐他汀负荷剂量进行研究。分析两组患者住院期间肌酸激酶同工酶与超敏C反应蛋白值,PCI术后与术后1个月心功能情况。结果显示围手术期阿托伐他汀负荷剂量组主要心血管事件发生率优于非阿托伐他汀组（P〈0．05）。因此,围手术期给予负荷剂量的阿托伐他汀可以降低住院期间不良心血管事件的发生率,改善患者预后。     

替罗非班不同给药途径对DM合并急性STEMI患者PCI术后血小板α-颗粒膜蛋白及心肌灌注水平的影响

为探讨替罗非班不同给药途径对糖尿病（DM）合并急性ST段抬高型心肌梗死（STEMI）患者PCI术后血小板α-颗粒膜蛋白及心肌灌注水平的影响,对149例DM合并急性STEMI患者进行研究,测定并比较经静脉（A组）、冠脉给药途径（B组）和无替罗非班（C组）的患者术前及术中应用替罗非班后血小板α-颗粒膜蛋白GMP140浓度、造影结果、心肌酶及肌钙蛋白I水平峰值及峰值时间、心电图变化。结果显示A、B两组术中血小板α-颗粒膜蛋白浓度较术前明显降低（P〈0．05）,且B组较A组降低更明显（P〈0．05）,而C组未见明显变化（P〉0．05）,A、B两组术后即刻TIMI血流、2h sumSTR、心肌酶及肌钙蛋白Ⅰ峰值及峰值时间的变化均优于C组（P〈0．05）,且B组优于A组（P〈0．05）。因此,替罗非班可以降低血小板α-颗粒膜蛋白浓度和改善心肌灌注水平,与静脉途径给药相比,经冠脉给药更具有优势。     

医疗风险、责任与对策

医疗风险是医疗实践中客观存在的一种具有不确定性、损害性事件,对患者、医院和医学的发展有着不利的影响。医疗风险的存在有着复杂的原因,因此,对医疗风险管理与防范也应该采取包括提高医疗技术水平、加强风险教育、实行医疗责任保险等多种手段。     

医患关系面临的课题:利益的冲突

我国当前医患间存在利益冲突的现实,并呈现出种种特点。医患间相互戒备的加深和防御性医疗的出现,不利于融洽和互动医患关系的形成,医院在引入市场某些机制和扩展自身财力时,应尽力维护中低收入者的医疗保健权利,损害病人的利益,同时坚持医学伦理学的四项原则,建立相互间的诚信,充分运用社会调节和医疗诉讼的杠杆,实行医务公开,有望调节和平衡这种利益冲突,使医患双方的利益得到合理的归缩。     

Movement segmentation and visual perturbation increase developmental differences in motor control and learning

We examined the developmental differences in motor control and learning of a two‐segment movement. One hundred and five participants (53 female) were divided into three age groups (7–8 years, 9–10 years and 19–27 years). They performed a two‐segment movement task in four conditions (full vision, fully disturbed vision, disturbed vision in the first movement segment and disturbed vision in the second movement segment). The results for movement accuracy and overall movement time show that children, especially younger children, are more susceptible to visual perturbations than adults. The adults’ movement time in one of the movement segments could be increased by disturbing the vision of the other movement segment. The children's movement time for the second movement segment increased when their vision of the first movement segment was disturbed. Disturbing the vision of the first movement segment decreased the percentage of central control of the second movement in younger children, but not in the other two age groups. The children's normalized jerk was more easily increased by visual perturbations. The children showed greater improvement after practice in the conditions of partial vision disturbance. As the participants’ age increased, practice tended to improve their feedforward motor control rather than their feedback motor control. These results suggest that children's central movement control improves with age and practice. We discuss the theoretical implications and practical significance of the differential effects of visual perturbation and movement segmentation upon motor control and learning from a developmental viewpoint.     

Eye movements and bisection behavior in spatial neglect syndrome: representational biases induced by the segment length and spatial dislocation of the stimulus

The present study explored behavioral and eye-movement measures in unilateral neglect patients in response to online bisection task (unfilled gap line). Two different tasks supported the bisection performance, a pointing and a grasping strategy. It was explored whether these different strategies may influence subjects’ behavioral and eye-movement measures in response to different segment features: segment length (from shorter to longer) and segment spatial dislocation (from right to left spatial location). Consistent spatial biases were found for both bisection responses, fixation count, and duration, as well as for the first fixation count in case of pointing task. An “extreme-left” gradient effect was suggested and discussed, with patients’ behavioral and eye measures more impaired. On the contrary, the patients’ performance overlaps with the controls’ one in case a grasping task. The direct link of visual pointing and grasping strategy, respectively, with the two cortical ventral and dorsal pathways was adduced to explain our results.     

The Theory-Practice Gap in Cognitive Behavioral Therapy: Reflections and a Modest Proposal to Bridge the Gap

This paper examines the issues related to the gap between theory and practice in the area of cognitive-behavioral therapy. The article begins with a review of the evidence for such a gap, and having demonstrated that the gap exists, provides a discussion of some of the factors that are likely important in its genesis and maintenance. The article then focuses on potential strategies to reduce the theory-practice gap that go beyond the common recommendation for both efficacy and effectiveness research. In particular, we provide recommendations for protocol planning and design, training and competency maintenance, dissemination research, and implementation and policy change. We conclude with the proposition that theory and research should not only inform practice, but that practice should have a reciprocal benefit on theory and research.

Being, Doing, and Knowing: Developing Ethical Competence in Health Care

There is a growing interest in ethical competence-building within nursing and health care practising. This tendency is accompanied by a remarkable growth of ethical guidelines. Ethical demands have also been laid down in laws. Present-day practitioners and researchers in health care are thereby left in a virtual cross-fire of various legislations, codes, and recommendations, all intended to guide behaviour. The aim of this paper was to investigate the role of ethical guidelines in the process of ethical competence-building within health care practice and medical research. A conceptual and critical philosophical analysis of some paragraphs of the Helsinki Declaration and of relevant literature was performed. Three major problems related to ethical guidelines were identified, namely, the interpretation problem (there is always a gap between the rule and the practice, which implies that ethical competence is needed for those who are to implement the guidelines); the multiplicity problem (the great number of codes, declarations, and laws might pull in different directions, which may confuse the health care providers who are to follow them); and the legalisation problem (ethics concerns may take on a legal form, where ethical reflection is replaced by a procedure of legal interpretations). Virtue ethics might be an alternative to a rule based approach. This position, however, can turn ethics into a tacit knowledge, leading to poorly reflected and inconsistent ethical decisions. Ethical competence must consist of both being (virtues) and doing (rules and principles), but also of knowing (critical reflection), and therefore a communicative based model is suggested.
