Methods: 1 To establish rat AS models, rats in the experiment were divided intofive groups: normal control group, hyperlipidemia group (fed with high-cholesterol diet), hyperlipidemia + vitaminDS group, hyperlipidemia + vitamin D3 + endothelium denudate group,losartan group (hyperlipidemia +vitamin D3 + endothelium denudate group treated with losartan).

本实验从AS的主要的三种发病机制出发，建立和比较了三种建立大鼠AS模型的方法；同时以该模型为基础，探讨了MMP-9/TIMP-1的动态平衡与AS的关系；也研究了血管组织及血浆血管紧张素H水平与AS的关系；探讨了AngⅡ 1型受体拮抗剂氯沙坦是否具有抗AS作用，以及机制如何。

在颈椎主动运动的过程中，由中枢神经所支配的神经运动取决于主动肌和拮抗肌刺激反应的时间和紧张程度。
