流速应答因子KLF2-4在血府逐瘀胶囊促进血瘀模型大鼠“活血生新脉”中的作用研究

流速应答因子KLF2-4在血府逐瘀胶囊促进血瘀模型大鼠“活血生新脉”中的作用研究摘要：本研究旨在探讨流速应答因子KLF2/4在血府逐瘀胶囊促进血瘀模型大鼠“活血生新脉”中的作用。首先采用铁皮石斛多糖和大豆异黄酮制备血府逐瘀胶囊，并建立血瘀模型大鼠。然后观察胶囊对血浆凝血指标、血管收缩和舒张反应、血管内皮细胞形态变化以及KLF2/4表达的影响。结果表明，血府逐瘀胶囊可显著降低血浆凝血指标、提高血管内皮细胞形态稳定性，从而调节血管紧张素II与一氧化氮代谢，增加内皮依赖性血管舒张反应，表现出明显的“活血生新脉”作用。进一步，胶囊可促进KLF2/4的表达，KLF2/4可能是介导其作用的关键因子之一。因此，我们推测，胶囊通过调节KLF2/4表达而对内皮功能和血管舒张能力产生正向调节作用，从而促进血瘀模型大鼠的“活血生新脉”。

Abstract:Thepurposeofthisstudywastoinvestigatetheeffectsofflow-responsivetranscriptionfactorsKLF2/4inpromoting"activatingbloodcirculationandgeneratingnewvessels"inratswithbloodstasisinducedbyHemostasistreatmentwithXuefuZhuyuCapsule.Firstly,theXuefuZhuyuCapsulewaspreparedwithDendrobiumpolysaccharidesandsoyisoflavones,andtheratmodelwithbloodstasiswasestablished.Then,theeffectsofthecapsuleonplasmacoagulationindicators,vascularcontractionandrelaxationresponse,vascularendothelialcellmorphologicalchangesandKLF2/4expressionwereobserved.TheresultsshowedthatXuefuZhuyuCapsulesignificantlyreducedtheplasmacoagulationindicatorsandimprovedthestabilityofendothelialcellmorphology,therebyregulatingangiotensinIIandnitricoxidemetabolism,increasingendothelium-dependentvascularrelaxationresponse,andshowingasignificant"activatingbloodcirculationandgeneratingnewvessels"effect.Furthermore,thecapsulecanpromotetheexpressionofKLF2/4,andKLF2/4maybeoneofthekeyfactorsthatmediateitseffect.Therefore,wespeculatethatthecapsuleregulatestheexpressionofKLF2/4andpositivelyregulatesendothelialfunctionandvascularrelaxationability,therebypromotingthe"activatingbloodcirculationandgeneratingnewvessels"inratswithbloodstasis.
