慢加急性肝衰竭(AClF)是肝硬化的一种严重并发症,其发病率和死亡率较高。先前研究已证明质子泵抑制剂(PPI)的应用与肝硬化的并发症[如肝性脑病(HE)和自发性细菌性腹膜炎(SBP)]有关。关于PPI治疗与肝硬化并发症相关的病理机制还有待进一步研究。然而,许多研究表明,PPI治疗,特别是长期使用,会导致肠道生态失调,这可能加重肠道细菌的易位,增强失代偿期肝硬化的慢性炎症状态。值得注意的是,炎症状态是发生AClF的患者的典型特征。在此背景下,本研究假设PPI治疗可能是AClF发生的一个易感因素,研究的目的是调查在倾向评分匹配的肝硬化患者群体中,PPI治疗是否是失代偿期肝硬化患者发生AClF的危险因素。

文献回顾发现课程改革研究中参照视角的确立经历了3个阶段,分别是从对西方课程理论的译介来认识域外课程改革的趋势、从学术争鸣中引发出如何正确对待国外课程理论的思考、从多维议题中形成我国课程改革应该参照什么的现实追问。研究认为,我国体育课程改革参照围绕着我国体育课程改革的理论基础与我国体育课程改革如何借鉴反思2个方面予以展开。据此提出研究展望:我国学者对体育课程改革理论问题的认识正在逐步走向深化,同时将对其做出更加深入的改良性研究;体育课程改革如何进行参照成为当前及今后亟待回答的研究问题及拓展方向;未来体育课程改革参照研究既要回归比较教育学视野,也要引入案例及实证研究方法,以此提高研究的深刻性与系统性。
