研究目的:

改善动脉僵硬度有益于心血管疾病的预防。研究表明,主动脉旁脂肪组织(PAT)可通过释放炎症介质而增加动脉僵硬度。然而,作为动脉僵硬度的危险因素,高脂血症能否通过促进PAT释放炎症介质而增加动脉僵硬度尚不明确。前期工作结果显示,与野生型小鼠相比,高脂血症小鼠(LDLr-/-小鼠)主动脉壁胶原蛋白表达增加,弹性蛋白表达减少,动脉僵硬度显著增加,并伴有PAT增生以及PAT释放的IL-6增加。在此基础上,我们拟比较单纯高脂血症患者和正常对照组的主动脉僵硬度和炎症介质水平,在人体内证实高脂血症可能通过增加炎症介质释放而增加动脉僵硬度。然后,将给予高脂血症患者降脂治疗的同时加用抗炎药物匹多莫德或安慰剂,首次在临床上验证匹多莫德用于改善高脂血症患者主动脉僵硬度的可能性。最后,我们将利用动物实验探讨匹多莫德改善动脉僵硬度的可能机制。本课题的完成将为改善动脉僵硬度提供新策略,具有重要的社会意义。  

Objectives of Study:

To improve arterial stiffness is beneficial to prevent cardiovascular disease (CVD). Studies have shown that periaotic tissue (PAT) could increase arterial stiffness by releasing inflammatory factors. However, as a risk factor of arterial stiffness, whether hyperlipidemia promote arterial stiffness through inflammatory factors released by PAT is unknown. Pre-test results showed that, compared with the wild-type mice, the aorta of LDLr-/- mice had more expression of collagen I, less expression of elastin, higher arterial stiffness accompanied by hyperplasia of PAT and more IL-6 released by PAT. On the basis, we intend to compare arterial stiffness and inflammatory factors between the hyperlipidemia and healthy people to verify that hyperlipidemia promote arterial stiffness through inflammatory factors. Then, we will give lipid-lowering therapy in patients with hyperlipidemia, while the addition of anti-inflammatory medicine (pidotimod) or placebo. This study is the first one to verify pidotimod could relieve arterial stiffness of patients with hyperlipidemia. Finally, we will explore the mechanisms how pidotimod relieves arterial stiffness. The completion of this project will provide a new strategy to relieve arterial stiffness and has very important social value.
