中文摘要: 动脉粥样硬化(AS)是一种脂质介导的慢性炎症性疾病,主要包括内皮功能损伤、炎症发生、形成斑块等阶段。TGF-β信号分子可以通过其下游物质Smads的转导路径对AS发展过程中不同阶段的细胞因子进行调控,在动脉粥样硬化的发展进程中及维持斑块稳定性方面起着重要作用。香青兰总黄酮是从新疆优势特色资源香青兰中提取得到的一类天然黄酮类活性成分,前期研究显示,香青兰总黄酮具有明显降低实验性动脉粥样硬化大鼠血脂的作用,其机制与TGF-β/Smads信号转导通路干预AS的机制密切相关。因此,本研究在前期研究基础上,采用现代药理学研究的新方法和新技术,将从TGF-β/Smad 信号转导通路着手, 探讨香青兰总黄酮 对TGF-β/Smad信号通路的调节作用和对动脉粥样硬化发生发展的影响,为香青兰总黄酮直接控制炎症机制治疗动脉粥样硬化提供理论和实践依据。研究结果对促进维药香青兰现代化研究具有一定的指导意义。

英文摘要: Atherosclerosis (AS) is a lipid mediated chronic inflammatory disease, include endothelial dysfunction, inflammation, plaque formation and other phases. TGF-β signaling molecules can regulate cell factors in different stages in the development process of AS through the transduction pathway of the downstream substance Smads,Transforming growth factor-β(TGF-β)/Smad signalpathway (TGF-be ta)/Smad in the process of the development of atherosclerosis and maintain a plaque stability plays an important role. Dracocephalum Moldavica total flavones (TFDM) is a kind of natural flavonoids obtained from the characteristic advantage resources Dracocephalum Moldavica in Xinjiang, preliminary studies showed that the TFDM has a significant effect in reducing the role of blood lipids on experimental atherosclerosis in rats, the mechanism is closely related to the TGF-beta/Smads. Therefore, on the basis of preliminary studies, the new methods and technologies of modern pharmacological research will be used in this study, and will start from the TGF-beta/Smads to explore regulating effect on TGF - beta/Smad signaling pathways and influence on the occurrence and development of atherosclerosis of TFDM, to provide theoretical and practical evidence for TFDM in direct control mechanism of inflammation in atherosclerosis. The results of the research will have certain guiding significance to promote the study of Dracocephalum Moldavica modernization.
