Although the model is performed in many countries similarly, the results differ from each other in accordance with the economic structure of relevant country In this regard, the aim of this paper is to investigate the effectiveness of monetary and fiscal policies on real activity and to find out causal relationship among questioned variables using OLS and causality methodologies in Turkish economy over the period 1998：1-2010： IV. Empirical findings indicate that only monetary policy has a significant positive effect on economic activity in the short run, Nonetheless, neither monetary nor fiscal policy has significant impact on real output in the long run. Causality analysis shows that there exists a unidirectional causality running from real output and money stock to government expenditures. Moreover, not surprisingly, it is also found that crisis experiences of Turkey in sample period have highly adverse impact on real activity. Causality analysis suggests us considering government expenditures as explained variable instead of real output. Hence, it can be concluded that St. Louis Model total spending equation is not applicable for Turkish economy during 1998-2010 periods展开更多
目的:研究基层医院在胸痛中心模式下急性ST段抬高型心肌梗死(STEMI)处理流程优化的可行性。方法:选取2022年3月—2023年3月胸痛中心模式下STEMI处理流程优化实施前收治的80例STEMI患者作为对照组;另选取2023年4月—2024年4月胸痛中心模...目的:研究基层医院在胸痛中心模式下急性ST段抬高型心肌梗死(STEMI)处理流程优化的可行性。方法:选取2022年3月—2023年3月胸痛中心模式下STEMI处理流程优化实施前收治的80例STEMI患者作为对照组;另选取2023年4月—2024年4月胸痛中心模式下STEMI处理流程优化实施后收治的80例STEMI患者作为观察组。对比两组救治时间以及心血管不良事件发生率。结果:观察组首次医疗接触至完成首份心电图时间(FMC2ECG)、从进入医院大门至签署手术知情同意书时间(DNT)、从进入医院大门至开始手术时间(D-to-S)、进入医院大门至球囊扩张时间(D2B)、导管室激活时间、首次医疗接触至服用双抗血小板药物时间(FMC to M)以及住院时间均短于对照组,有统计学差异(P<0.05);观察组恶性心律失常、心力衰竭等心血管不良事件总发生率低于对照组,有统计学差异(P<0.05)。结论:通过胸痛中心模式下STEMI处理流程优化,能够使STEMI患者更早、更快速达到导管室开展急诊PCI术治疗,有效缩短患者各项救治时间,尽最大可能挽救患者生命,并降低心血管不良事件发生风险。展开更多
