摘要
目的探讨骨关节炎中基质金属蛋白酶9(MMP-9)、白介素6(IL-6)mRNA和蛋白的表达。方法采用免疫组织化学技术检测60例骨关节炎病例(OA组)及20例正常对照关节软骨及滑膜MMP-9、IL-6蛋白的表达水平;采用原位分子杂交技术检测30例OA及10例正常对照关节软骨及滑膜MMP-9、IL-6 mRNA的表达水平。结果 MMP-9 mRNA和蛋白在OA组阳性表达的积分光密度(IOD)值均高于正常对照组[(8.38±2.29)vs(3.52±1.36),P<0.01;(9.18±3.58)vs(3.83±1.48),P<0.01],OA中二者的表达正相关性(r=0.924,P<0.01);IL-6 mRNA和蛋白在OA组阳性表达的IOD值均高于正常对照组[(8.74±3.62)vs(5.91±1.53),P<0.01;(8.96±3.57)vs(6.87±1.43),P<0.01],OA中二者的表达亦正相关(r=0.917,P<0.01);MMP-9 mRNA、IL-6 mRNA及相应蛋白在OA中的表达均正相关(原位杂交r=0.426,P<0.05;免疫组化r=0.444,P<0.01)。结论 MMP-9、IL-6在OA关节软骨与滑膜中呈高表达,二者对OA的发生发展可能起促进作用。
