Serum expression of monocyte chemoattractant protein-1 and macrophage inhibitory protein-1? in patients with rheumatoid arthritis / 第二军医大学学报

ABSTRACT

Objective:To investigate the possible role of chemokines monocyte chemoattractant protein-1(MCP-1) and macrophage inhibitory protein-1(MIP-1?) in pathogenesis of rheumatoid arthritis(RA).Methods: Enzyme linked immunosorbent assay(ELISA) was used to determine the serum expression of MCP-1 and MIP-1? in 17 patients with early active RA,18 with advanced active RA,and 15 healthy controls(all aged 18-79 years).Clinical activity indices such as the strength of grip,joint pain index,and joint swelling index were assessed in all subjects;and the serological indices such as erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),and rheumatoid factors were also determined.The relationships between serum levels of MCP-1, MIP-1? with the clinical activity indices and serological indices were analyzed.Results: The serum levels of MCP-1 in patients with early and advanced RA were higher than that in the controls(P
