摘要:

背景:Ⅱ型胶原和硫酸软骨素是关节软骨的重要组成成分,不仅具有保护软骨的作用,还能抑制关节炎的病变。
目的:通过检测类风湿因子和C-反应蛋白的表达评价Ⅱ型胶原及Ⅱ型胶原复合硫酸软骨素注射对骨性关节炎的疗效。
方法:采用改良Hulth法制作大鼠膝关节骨性关节炎模型,造模后模型组关节腔注射生理盐水、透明质酸钠组给予透明质酸钠凝胶注射、Ⅱ型胶原组给予单纯Ⅱ型胶原注射、Ⅱ型胶原复合硫酸软骨素组给予Ⅱ型胶原复合硫酸软骨素注射治疗。各组动物于术后进行日常观察、称质量、血清抗体及组织病理检查。
结果与结论:造模后模型组大鼠血类风湿因子和C-反应蛋白水平均有所升高,炎症加剧;而与模型组相比,各给药组大鼠类风湿因子和C-反应蛋白水平均有所下降,炎症有所减轻,其中Ⅱ型胶原复合硫酸软骨素组大鼠血清中类风湿因子水平显著下降(P < 0.01)。结果显示Ⅱ型胶原与透明质酸钠均具有预防和治疗骨关节炎的作用,能缓解骨关节炎病变,Ⅱ型胶原联合硫酸软骨素的疗效更明显。

Abstract:

BACKGROUND: Type Ⅱ collagen and chondroitin sulfate are the major components of articular cartilage. They cannot only protect the cartilage, but also inhibit pathology of osteoarthritis.
OBJECTIVE: To evaluate the curative effect of type Ⅱ collagen injection and type Ⅱ collagen- chondroitin sulfate composite injection on osteoarthritis by detecting the expression of rheumatoid factor and C-reactive protein.
METHODS: A rat model of knee osteoarthritis was established by using improved Hulth’s method. The treatment was performed via injection into the articular cavity (treatment group A: type Ⅱ collagen injection; treatment group B: type Ⅱ collagen-chondroitin sulfate composite injection; positive control: sodium hyaluronate; model control: physiological saline). After operation, rats in each group were characterized with daily observation, weighing, serum antibody test and histological observation.
RESULTS AND CONCLUSION: After treatment, the content of rheumatoid factor and C-reactive protein in rats’ serum of model group was increased, and inflammation was aggravated; while compared with the model group, the content of rheumatoid factor and C-reactive protein in the other groups, especially in the treatment group B, were lower and the inflammation was eased (P < 0.01). The findings show that both type Ⅱ collagen and sodium hyaluronate can prevent and treat osteoarthritis effectively. The therapeutic effect of type Ⅱ collagen combined with chondroitin sulfate is better.
