中文摘要:
目的:在建立不同强度风寒湿痹证型颈椎病动物模型的基础上,检测实验家兔颈椎间盘组织中胶原酶(MMP1)、中性蛋白多糖酶(MMP3)活性变化。
方法:8月龄雄性新西兰白兔24只,随机分为正常对照组和轻度、中度、重度刺激组。采用刺激条件是温度5℃±0.5℃,湿度100%,风力6级,按轻、中、重度刺激组的不同要求,分别给予32、64和128小时的间断重复刺激,每日刺激4小时。分别采用3MH-Ⅰ型胶原蛋白法和免疫一步夹心法检测MMP-1、MMP-3活性。
结果:各个模型组退变指数都有不同程度上升,重度刺激组较正常对照组有统计学差异(P<0.05)。模型组与对照组比较,中、重度刺激组MMP-1和MMP-3活性升高明显(P<0.01),轻度刺激组变化不明显;模型组之间比较,中、重度刺激组MMP-1、MMP-3活性明显高于轻度刺激组(P<0.01)。
结论:中、重度风寒湿刺激家兔颈椎间盘退变后使MMP1和MMP3活性升高,加速椎间盘细胞外基质降解,导致颈椎间盘退变。 |

ABSTRACT
Objective:To establish cervical spondylosis animal models of Wind Cold Dampness arthralgia syndrome type.The morphologic state of the discs of the rabbits was observed with light microscope,and the activity of metalloproteinase 1,metalloproteinase 3 in the discs was assayed with biochemical.
Methods:Twenty four 8 months old rabbits were randomly allocated into four groups of the control,light,medium and heavy irritancy groups with 6 animals in each.The basic condition of Wind Cold Dampness is 6 class force of wind, 5℃±0.5℃ and 100% humidity.32,64,128 hours of continuous irritancy were applied on light,medium and heavy irritancy group respectively.The daily period of irritancy was 4 hour.
Results:The degree index number of intervertebral discs degeneration was elevated in every irritancy group,and in the heavy irritancy group the increase was significantly higher(P<0.05).MMP 1 and MMP 3 activities of cervical intervertebral discs in middle and heavy irritancy group,MMP 1 and MMP 3 activity in medium and heavy irritancy group were significantly higher than that in the control group respectively(P<0.01).
Conclusion:MMP 1 and MMP 3 activity were increased by medium and heavy Wind Cold Dampness irritancy.Acceleration of degradation of extracelluar matrix of cervical intervertebral discs resulted in degeneration of cervical intervertebral discs. |
