Abstract: Objective To evaluate the expression and clinical significance of matrix metalloproteinase 14(MMP-14) in osteoar-thritis(OA) patients in synovium and synovial fluid of knee joint .Methods Semi-quantitative RT-PCR were used to detect the ex-pression of MMP-14 mRNA in 32 case of OA (experimental group)and 26 non-OA patients(control group)synovium ;protein level expression of MMP-14 in synovial fluid were analyzed by ELISA .Results The expression of MMP-14 mRNA in experimental group synovium of knee joint was significantly increased compared with control group (P<0 .05);but the protein level of MMP-14 was low in experimental group synovial fluid compared with control group (P<0 .05) .Conclusion The expression of MMP-14 is increased in OA patients synovium and maybe promote the progress of OA directly ;the protein level of MMP-14 is decreased in OA synovial fluid ,indicated the function of MMP-14 in OA synoviocyte indirectly .
