Abstract:

Objective To investigate the correlation between the expression levels of matrix metalloproteinase(MMP) mRNA and a disintegrin and metalloproteinase with thrombospondin motifs(ADAMTS) mRNA with the degree of intervertebral disc degeneration. Methods A total of 160 disc degenerative disease patients were enrolled,and according to the results of magnetic resonance imaging(MRI) and Pfirrmann classification method,they were classified into Ⅰ level(30 cases),Ⅱ level(32 cases),Ⅲ level(35 cases),Ⅳ level(33 cases) and Ⅴ level(30 cases). The expressions of MMP-1 mRNA,MMP-3 mRNA,MMP-9 mRNA,MMP-13 mRNA,ADAMTS-1 mRNA,ADAMTS-4 mRNA,ADAMTS-5 mRNA,interleukin(IL)-1α mRNA,IL-1β mRNA,IL-6 mRNA and IL-8 mRNA in the nucleus pulposus were determined. Spearman correlation analysis was used to evaluate the correlation between each indicator and Pfirrmann classification,and Pearson correlation analysis was used to evaluate the correlation between each indicator. Results The relative expressions of MMP-3 mRNA,MMP-9 mRNA,IL-1α mRNA and IL-1β mRNA in Ⅳ and Ⅴ level groups were higher than those in Ⅰ,Ⅱ and Ⅲ level groups(P<0.05),and those in Ⅰ,Ⅱ and Ⅲ groups were increased in turn(P<0.05). The relative expressions of ADAMTS-4 mRNA and ADAMTS-5 mRNA were higher in Ⅲ,Ⅳ and Ⅴ level groups than those in Ⅰ and Ⅱ level groups(P<0.05),and those in Ⅱ level group was higher than those in Ⅰ level group(P<0.05). There was no statistical significance for the other indicators(P>0.05). Spearman correlation analysis showed that the relative expressions of MMP-3 mRNA,MMP-9 mRNA,ADAMTS-4 mRNA,ADAMTS-5 mRNA,IL-1α mRNA and IL-1β mRNA were positively correlated with Pfirrmann classification(P<0.05). Pearson correlation analysis showed that the relative expressions of MMP-3 mRNA,MMP-9 mRNA,ADAMTS-4 mRNA and ADAMTS-5 mRNA were positively correlated with the relative expressions of IL-1α mRNA and IL-1β mRNA(P<0.05). Conclusions MMP-3,MMP-9,ADAMTS-4,ADAMTS-5,IL-1α and IL-1β are related to the occurrence and development of intervertebral disc degeneration,which can reflect the severity of the disease.
