目的探讨绿原酸(chlorogenic acid,CGA)通过同源性磷酸酶张力蛋白诱导激酶1(PINK1)/帕金森蛋白(Parkin)信号通路对ox-LDL诱导的泡沫细胞线粒体自噬及炎症反应的调控作用。方法将RAW264.7巨噬细胞分为正常(Control)组、模型(Model)组、CGA低剂量(CGA-L)组、中剂量(CGA-M)组、高剂量(CGA-H)组、CGA-H+Mdivi-1(CGA-H+Mdi)组。油红O法鉴定细胞泡沫化;CCK-8法确定CGA干预浓度;透射电镜观察细胞线粒体结构改变;ELISA检测IL-1β、IL-18、IFN-γ表达;qRT-PCR及免疫荧光标记法检测PINK1/Parkin线粒体自噬通路相关基因及蛋白表达。结果油红O染色显示泡沫细胞模型制备成功。与Model组相比,不同浓度CGA干预后细胞线粒体损伤明显减轻,诱导了PINK1、Parkin、p-Parkin、PHB2、LC3Ⅱ表达,抑制了TOMM20表达,以及降低了IL-1β、IL-18、IFN-γ的表达(P<0.05或P<0.01);与CGA-H组相比,CGA-H+Mdi组细胞线粒体损伤明显加重,抑制了PINK1、Parkin、p-Parkin、PHB2、LC3Ⅱ表达,诱导了TOMM20表达,以及增强了IL-1β、IL-18、IFN-γ表达(P<0.01)。结论CGA可通过调控PINK1/Parkin通路诱导泡沫细胞线粒体自噬以及抑制了促炎因子IL-1β、IL-18、IFN-γ过表达,这可能是CGA抗动脉粥样硬化机制之一。

近年来,我国自然灾害频发,对人民群众的生命财产安全造成极大威胁.实践证明,政企合作储备与运输应急物资有利于更好地备灾、救灾.尽管我国的政企合作已经初具规模,但是无论是研究还是实践中,这些合作主要考虑的仍然是双方的成本,忽视了灾民长时间缺乏应急物资所产生的痛苦,而减轻这种痛苦恰好是应急物流的根本目的,是应急物流与商业物流的本质区别,有利于更好地贯彻“以人为本”的救灾理念.为此,本文引入匮乏成本,用以衡量灾民因缺乏应急物资而产生的痛苦,并以此为基础针对以下核心问题进行了研究与探索:1)在考虑异质化运输条件的情况下,如何确定应急物资的储备量以及价格以保证政府与企业达成双赢?2)不同的应急物流情境(不同的应急物资、需求分布以及匮乏成本权重)会对政企合作造成怎样的影响?为解决上述研究问题,本文建立了基于斯塔克伯格博弈的政企合作模型,并通过数值算例以及敏感度分析,对模型的可行性进行了验证.本文通过引入匮乏成本,提出了由于长时间物资匮乏造成的灾民痛苦的衡量工具,拓宽了政企合作应急物流的研究思路,有利于践行“以人为本”的思想,为实际应急物流运作提供模型工具与理论基础.
