为了探讨重症急性胰腺炎(SAP)并发急性呼吸窘迫综合征(ARDs)的危险因素,回顾性分析了我院76例SAP患者入ICU时的年龄、血糖、APACHEⅡ评分等17项指标,根据是否合并ARDS对各项指标进行单因素及多因素Logistic回归分析。单因素分析显示两组在年龄、呼吸频率、血糖、感染、APACHEⅡ评分、Ranson评分、CT评分、ICU住院日方面差异有显著性(P〈0.05),多因素Logistic回归分析显示年龄、血糖、感染、APACHEⅡ、Ranson、CT评分与SAP并发ARDS有关。故得出结论,年龄、血糖、感染、APACHEⅡ、Ranson与CT评分是SAP并发ARDS的独立危险因素。  相似文献

浅谈心血管疾病预防的重要性和可操作性   总被引:1,自引:0,他引:1  
心血管疾病是人类死亡的主要病因,其危险因素包括吸烟、血脂异常、糖尿病、高血压、肥胖等。目前我国医务工作者限于治疗疾病,忽视疾病预防,这种模式过于被动,需要高昂的医疗支出。如果不做好心血管疾病的预防工作,将会极大影响国民经济增长。因此改善生活方式、预防心血管疾病发生,形成疾病预防模式就显得尤为重要,并具有可操作性。  相似文献

通过对2型糖尿病心血管终点事件的观察,更多的临床证据提示,糖尿病的治疗目标应该以减少心血管事件为主。糖尿病防治从策略上发生了两个转变,即以血糖为中心转向以防治心血管事件为中心的多危险因素综合防治策略;以糖化血红蛋白检测作为血糖评价的金标准转向以血糖量、质、时程控制的全面评价策略。  相似文献

Research has generally found a “dose relationship” between potentially traumatic events (PTEs) and the likelihood of developing PTSD, with greater number of events associated with greater likelihood. Most of these studies have been cross-sectional, however. A recent prospective study (Breslau, Peterson, & Schultz, 2008) found that PTSD response to prior potentially traumatic event (PTE) exposure, rather than prior exposure itself, acts as a risk factor for PTSD in response to subsequent PTE; however, this analysis combined many different types of events, and the unique contribution of specific events (e.g., assault) that may be associated with differential risk of PTSD was indeterminable. The present study examined the effects of cumulative PTE exposure prospectively using a two-wave design in the National Survey of Adolescents (N = 1703). History of assault and witnessing serious violence were the focal PTEs examined. Wave I assault without PTSD was found to predict PTSD at Wave II following exposure to new assault or witnessed violence; however, among those without prior PTSD, Wave I witnessed violence did not increase risk of subsequent PTSD following exposure.  相似文献

Trait anger and anger expression style in children's risky decisions   总被引:1,自引:0,他引:1  
In this study, 104 children completed a task, measuring risk decision-making, and the State-Trait Anger Expression Inventory for Children and Adolescents. Subjects were also asked to evaluate the degree of danger, benefit, fun and fear perceived for each risky choice. Analyses indicated that (a) risk decision-making was predicted by both trait anger and outward expression of anger; (b) appraisal of danger fully mediated the relationship between trait anger and risk; (c) perceptions of benefit, scare and fun partially mediated the relationship between trait anger and risk; and (d) appraisal of danger partially mediated the relationship between outward expression of anger and risk decision-making. The results provide evidence for a relationship between dispositional anger and risk decision-making during childhood, suggesting a possible explanation of the mechanisms below. In particular, risk decision-making can be viewed as the output of cognitive and emotive processes, linked to dispositional anger that leads children to be amused, optimistic and fearless in potentially risky situations. These findings substantiate the importance of incorporating cognitive and emotive factors in theories that seek to explain the relationship between personality traits and risk decision-making across a broad age range.  相似文献

Eysenck’s arousal hypothesis suggests that introverts have greater cortical activity than extraverts. This prediction was tested in several studies that used the electroencephalogram (EEG) alpha activity to index cortical arousal, but empirical findings are inconsistent. Possibly, external factors of the measurement situation or static factors such as skull thickness may act as nuisance variables on alpha activity and thus mitigate the relation between arousal and extraversion. The aim of the present study was to test the arousal hypothesis with a focus on these methodological issues. Resting EEG was acquired on several occasions of measurement, skull thickness was quantified with anatomical magnetic resonance imaging (MRI), and extraversion was assessed by questionnaire. There was a positive association between alpha activity and extraversion, which was neither affected by external factors nor by skull thickness. This finding is in line with the arousal hypothesis and suggests that external or static factors do not contribute to the inconsistency of empirical findings.  相似文献

Reinforcement sensitivity theory (RST; Gray, 1987; Gray & McNaughton, 2000) has proven to be a valuable tool for understanding psychopathy (e.g., Fowles, 1980, 1988; Newman & Malterer, 2009; Poythress et al., 2008). Recent research has linked two RST constructs, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS), to individuals with primary psychopathy and secondary psychopathy (Lykken, 1995; Newman, MacCoon, Vaughn, & Sadeh, 2005): Primary psychopaths manifest low BIS reactivity and secondary psychopaths manifest high BAS reactivity. In the present study, we examine the relationships between the BIS/BAS constructs and Factors 1 and 2 of the Psychopathy Checklist – Revised (PCL-R) in a sample of 472 incarcerated male offenders. Paralleling their relationships with primary and secondary psychopathy, the BIS/BAS constructs were differentially related to the two PCL-R factors. Specifically, the influence of the BIS was found to be more prominent than the influence of the BAS for Factor 1, and the influence of the BAS was more prominent than that of the BIS for Factor 2.  相似文献

12-20岁个体前瞻记忆的发展与影响因素的研究   总被引:1,自引:0,他引:1  
刘伟  黎琳 《心理科学》2007,30(3):555-557
以334名12~20岁个体为被试,采用两因素混合设计,探讨这一年龄阶段个体前瞻记忆的发展及影响因素。结果发现,被试前瞻记忆水平随年龄增长而提高,且在14~16岁发展最快;提高基于时间的前瞻记忆负载,会使前瞻记忆成绩降低;前瞻记忆与当前任务的完成呈负相关。表明前瞻记忆是一种策略加工过程。  相似文献

推理是人们认知的根本。人们在推理过程中,受到许多因素的影响,大致可以分为内在(个体差异)因素和外在(任务)因素。该文主要针对影响三段论推理的内在因素(个体差异)进行评论,并且讨论了将来的研究方向。  相似文献

The author presents several arguments against Toomela’s (Culture of science: Strange history of the methodological thinking in psychology. Integrative Psychological and Behavioral Science, 2007a, doi:, History of methodology in psychology: Starting point, not the goal. Integrative Psychological and Behavioral Science, 2007b, doi:) pessimistic thesis: “The last 60 years of research in psychology seems to have gone astray.” Nevertheless he admits that Toomela’s article despite the excessively categorical assessments contained in it and the undue pessimism crowing its conclusion, represents a substantial contribution to the highlighting of socio-cultural impact on various models of psychological cognition, which lurks behind the international unification of globalizing science.
