为探讨直接经皮冠状动脉介入治疗(PCI)首次急性前壁心肌梗死患者,在不同剂量他汀药物治疗后住院期间疗效比较,纳入首次诊断为急性前壁心肌梗死并接受直接PCI治疗的患者140例,随机分为强化治疗组和对照组。强化治疗组入院时顿服阿托伐他汀80mg,术后40mg/晚,直至出院;对照组口服阿托伐他汀20mg/晚。术前及术后、出院前测定心肌标记物,术前及出院前测定血浆氨基末端B型利钠肽前体(NT—proBNP),采用彩色多普勒超声检测左室射血分数(LVEF)的变化,同时记录住院期间主要心脏不良事件(MACEs)的发生。结果出院时LVEF值差异无统计学意义(P=0.249),NT—proBNP出院前较术前升高,对照组升高显著(P=0.000)。组间比较NT—proBNP,对照组显著高于强化组(P=0.020)。住院期间两组患者无MACEs发生。首次急性前壁心肌梗死患者直接PCI后,强化阿托伐他汀治疗短期内可改善左心功能。  相似文献

急腹症是外科常见病和多发病,它是一种以急性腹痛为主要表现的临床急症,临床上常有误诊发生,最终造成严重后果。因而在诊疗过程中,必须对急性腹痛尽快作出定位、定性及病因诊断,以防误诊误治。现将我科收治的子宫穿孔误诊为消化道穿孔和输卵管卵巢脓肿误诊为阑尾周围脓肿的2例以急腹症表现为首发症状的患者在我科室的诊治过程及经验进行总结并进行分析,为临床能够提高急腹症的诊率断,降低误诊率提供借鉴,提高临床医生的鉴别能力,保证患者的身心健康。  相似文献

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。  相似文献

What motivates clergy political attitudes and behavior? We investigate this using a questions‐as‐treatment randomized experiment focusing on Roman Catholic priests in the United States. Our results suggest substantial utility in using a question frame referencing the distinct institutional expectations that clergy regularly confront. Specifically, when randomly primed to consider the expectations of institutional reference groups, clergy exhibit significantly higher levels of conservatism and report higher levels of political engagement, which is in line with their church's institutional preferences more generally. Our findings underscore the need for experimental methodology to make increased inroads into understanding political outcomes in religious contexts.  相似文献

The purpose of this study was to identify the latent variable structure of a measure of cultural capital in the community college field. The community college was used based on its emergence as both a gateway and a gatekeeper to higher education, and as a power structure that can afford both social and economic opportunities through degree attainment for underrepresented groups. Therefore, implications for counselors in various settings were highlighted, along with implications for future research. El propósito de este estudio fue identificar la estructura de la variable latente de una medida de capital cultural en el campo de los colegios comunitarios. Se usó el colegio comunitario por su surgimiento como ambos filtro y puerta de entrada a la educación superior, así como una estructura de poder que puede ofrecer oportunidades sociales y económicas a grupos infrarrepresentados a través de la obtención de grados. Por lo tanto, se destacaron las implicaciones para consejeros en entornos variados, junto con las implicaciones para investigaciones futuras.  相似文献

采用日记追踪法,以53名老年人为被试,探讨日常小团体的多样性对其身体症状的影响及机制。结果显示:(1)日常小团体内多样性负向预测老年人当天的身体症状;(2)在个体内水平,团体积极情绪在老年人小团体内多样性对身体症状的关系中起中介作用;(3)心理压力感能够跨层正向调节日常小团体内多样性对每日身体症状的影响。研究结果有助于揭示小团体多样性如何与老年人身体症状相联系,以及两者之间的关系在何种条件下更强,这对于老年人身体症状的干预工作具有一定实践意义。  相似文献

Prospect theory offers a number of advantages that justify its use in the analysis of political behavior, but it also has some aspects that limit its wider applicability in political contexts. This article reviews recent research highlighting these successes and limitations. Future research on the incorporation of prospect theory into models of political behavior should focus on such areas as group decision-making, reference point specification, and emotion.  相似文献

酒精性肝病是导致我国肝脏损害的第二大原因,已成为最严重的健康问题之一。我国已经迎来了酒精性肝病的高峰时期,并将会持续增长,卫生系统将面临巨大的压力。然而,对于酒精性肝病本身,还存在着诊断、治疗、预防等众多医学困惑;饮酒的危害不仅仅局限在肝脏,还可引起全身多器官的损害;酒害也早已超越了医疗界,是一个严重的社会问题。对于酒精性肝病的防治需要全社会共同参与,并且将是一条极其漫长而艰难的路程。  相似文献

Previous work studying social comparisons suggests that people are likely to assimilate to ingroup members (e.g. Ledgerwood & Chaiken, 2007) but can also contrast from ingroup members if outgroup members are present (Blanton, Miller, & Dye, 2002). The present research built upon these findings by including a no-comparison control group to test for true contrast and assimilation effects. Across two studies, women primed with a gender-math stereotype received false feedback about their performance on a math task; and in some conditions, they learned of the performance of ostensible male and/or female co-participants. Relative to a no-comparison control, we did not see evidence of ingroup assimilation in either study. However, in both studies, we found that participants were likely to contrast their self-evaluations away from downward targets, regardless of group membership. This suggests that self-enhancement motivations may be stronger than the drive for ingroup assimilation.  相似文献

An extraordinary physiological capacity combined with remarkable motor control, perception, and cognitive functioning is crucial for high performance in sports. Tests that assess the physical abilities are already well established. Moreover, a growing area of research evolved in the recent past that is particularly concerned with the basic cognitive functions by means of neurocognitive tests in experts and elite athletes. The aim of this meta‐analysis (k = 19) is to quantify differences among experts and nonexperts as well as elite athletes and non‐elite athletes. In addition, it aims to assemble and compare previous research and analyze possible differences in cognitive functions depending on age, skill level, and used cognitive tasks. Overall, the mean effect size was small to medium (r = 0.22), indicating superior cognitive functions in experts and elite athletes. The factor of skill definition significantly differentiates the cognition–expertise relationship. In contrast, differences in age groups and cognitive areas appeared but were not significant. Future research should prefer the elite rather than the expert definition and distinguish between high‐performance and amateur athletes. Furthermore, the findings suggest that it can be beneficial for coaches and sport clubs to integrate cognitive tests as an additional tool for scouting and for optimizing the athletic development of their players.  相似文献
