摘要:

背景:目前发现的促进血管增生活性最强的是血管内皮生长因子,其在类风湿关节炎滑膜细胞呈现强表达。
目的:观察对胶原诱导性关节炎大鼠不同时间点滑膜血管内皮生长因子表达和微血管计数的变化,探讨血管内皮生长因子和微血管在类风湿关节炎发病机制中的作用及其相关性。
方法:采用Ⅱ型胶原与完全福氏佐剂诱导SD大鼠实验性关节炎模型,采用免疫组织化学方法观察实验性关节炎大鼠不同时间点滑膜组织血管内皮生长因子的表达水平和新生血管计数,并同时观察发病时间与关节炎指数积分、血管内皮生长因子及滑膜新生血管数之间的关系。用直线相关分析法分析血管内皮生长因子表达与滑膜新生血管数之间的关系,用等级相关分析法分析关节炎指数积分与血管内皮生长因子表达及滑膜新生血管数之间的关系。
结果与结论:随着实验性关节炎发病时间的延长,滑膜新生血管逐渐增多,滑膜增厚,关节炎指数积分逐渐增加,血管内皮生长因子表达水平和微血管数也随之升高;其关节炎指数积分与血管内皮生长因子表达水平呈正相关关系(r=0.535、P < 0.05), 血管内皮生长因子表达水平与微血管计数呈显著正相关关系(r=0.860,P < 0.01) 。血管内皮生长因子参与了实验性关节炎大鼠滑膜血管翳的形成过程,血管内皮生长因子与微血管密度在类风湿关节炎的发病中具有重要意义。

Abstract:

BACKGROUND: Vascular endothelial growth factor is found the strongest to promote angiogenesis, which show strong expression in synovial cells in rheumatoid arthritis.
OBJECTIVE: To evaluate the relation between the expression of vascular endothelial growth factor and microvessel density in rheumatoid arthritis.
METHODS: Collagen II and complete Freund’s adjuvant were used to induce experimental arthritis in Sprague-Dawley rats. Synovium expression of vascular endothelium growth factor and microvessel density were assayed at different time points using immunohistochemistry method, and changes in new vessels, vascular endothelial growth factor expression and arthritis index were observed along the time course. The correlations between vascular endothelial growth factor expression and number of new blood vessels as well as between arthritis index and vascular endothelial growth factor expression were studied with linear correlation analysis and rank correlation analysis, respectively.
RESULTS AND CONCLUSION: With the time lasting, new blood vessels in the synovium proliferated, the synovium was thickened, and the arthritis index rose gradually as well as vascular endothelial growth factor expression and number of new microvessels were on the rise. Vascular endothelial growth factor expression was 
positively correlated with arthritis index (r=0.535, P < 0.05) and significantly positively correlated with number of new microvessels (r=0.860, P < 0.01). Vascular endothelial growth factor is involved in the course of synovium pannus response, and vascular endothelial growth factor and microvessel density may play an important role in rheumatoid arthritis pathogenesis.
