Abstract

Objective To investigate the expression of monocyte chemoattractant protein-1(MCP-1)and CCR2 in peripheral blood and pleural fluid of tuberculous pleurisy patients.Methods Flow cytometry was used to detect the expression of CCR2 in the peripheral blood mononuclear cell and pleural fluid cell of tuberculous pleurisy patients;ELISA was used to detect the content of MCP-1 in serum and pleural fluid.Results MCP-1 in surem and pleural fluid and CCR2 in the peripheral blood mononuclear cell and pleural fluid cell of tuberculous pleurisy patients was significantly higher than that of the healthy normal controls[MCP-1:(340.8±220.8)and(9.0±3.8)ng/L,P＜0.01;CCR2(18.2±10.1)%and(6.9±3.5)%,P＜0.05];Both MCP-1 and CCR2 were detected in pleural fluid and both of them were positivley correlated(r=0.227,P＜0.05).Conclusion The expression of MCP-1 and CCR2 in peripheral blood of tuberculous pleurisy patient are significantly elevated which are significance molecule participating in the pathogenesis of tuberculous pleurisy. Key words: Monocyte chemoattractant protein-1; CCR2; Tuberculous pleurisy
