急性胰腺炎患者血漿內(nèi)皮細(xì)胞微粒水平改變及其形成機(jī)制的初步研究

急性胰腺炎患者血漿內(nèi)皮細(xì)胞微粒水平改變及其形成機(jī)制的初步研究急性胰腺炎患者血漿內(nèi)皮細(xì)胞微粒水平改變及其形成機(jī)制的初步研究

摘要：

本研究旨在探究急性胰腺炎患者血漿內(nèi)皮細(xì)胞微粒的變化水平以及其形成機(jī)制。采用自身對照的方式研究了26例被確診為急性胰腺炎患者的血漿樣本和26例健康人的血漿樣本。結(jié)果表明，在急性胰腺炎患者的血漿中，內(nèi)皮細(xì)胞微粒（EPMs）的含量明顯高于健康人的血漿中的含量；在急性胰腺炎患者血漿EPMs水平與可能的危險因素之間進(jìn)一步進(jìn)行了研究，發(fā)現(xiàn)肝功異常和炎癥反應(yīng)水平提高與EPMs水平顯著相關(guān)。此外，我們還進(jìn)一步研究了EPMs的可能形成機(jī)制，發(fā)現(xiàn)炎癥因子IL-6、TNF-α和IL-1β似乎可以通過促進(jìn)EPMs的內(nèi)皮細(xì)胞釋放來促進(jìn)炎癥反應(yīng)。因此，EPMs在急性胰腺炎的發(fā)病和發(fā)展中扮演著重要的角色，并且其可能是炎癥進(jìn)程中的一個重要參與者。
