基质金属蛋白酶-1与基质金属蛋白酶抑制剂-1在纤维性肌性斜颈患儿中的表达

目的探讨基质金属蛋白酶-1(MMP-1)和基质金属蛋白酶抑制剂-1(TIMP-1)在先天性纤维型肌性斜颈胸锁乳突肌的表达。方法采用Masson三色胶原染色法观察先天性肌性斜颈患儿胶原的增生情况,并进行肌肉型和纤维型分组,获得纤维型标本22例,应用免疫组织化学染色法观察MMP-1、TIMP-1在纤维型组中的表达情况,并与6例对照组比较。结果免疫组织化学染色显示,MMP-1在先天性纤维型肌性斜颈胸锁乳突肌患儿明显减少,与对照组比较有显著性差异(P<0.01);先天性纤维型肌性斜颈胸锁乳突肌患儿TIMP-1表达与对照组比较无显著性差异(P>0.05)。结论先天性肌性斜颈胸锁乳突肌的纤维化与MMP-1减少有关。

Expression of Matrix Metalloproteinase - 1 and Tissue Inhibitor of Metalloproteinase - 1 in Fibra Muscular Torticollis in Children

Objective To explore the expressions of matrix metalloproteinases-1(MMP-1) and tissue inhibitor of metalloproteinase-1(TIMP-1) in sternomastoid muscle and explore the pathogenesis of sternomastoid muscle fibrosis in congenital fibra muscular torticollis in children.Methods The hyperplastic state of collagen fiber were determine by Masson collagen stainning method and muscular torticollis and fibra torticollis was differed,obtained 22 cases of the fibra torticollis group.Immunohistochemical method was used to determine the expression of MMP-1 and TIMP-1 in sternomastoid muscle of fibra torticollis and compared them with 6 cases of control group.Results By the immunohistochemical method,the expression of MMP-1 in the experiment group significantly decreased than that in control group(P<0.01),but the expression of TIMP-1 was no significant difference between 2 groups(P>0.05).Conclusion In congenital fibra torticollis,the sternomastoid muscle fibrosis is related to the decrease of MMP-1.
