The numbers of different subsets of monocytes were examined in these two groups of subjects by flow cytometry. The concentrations of plasma interleukin(IL)-10 and IL-12 were determined by cytometric bead array. The acute physiology and chronic health evaluation(APACHE) II scores of individual patients were evaluated, and the levels of plasma C-reactive protein(CRP) as well as the activities of amylase and lipase were measured. RESULTS In comparison with that in the controls, significantly increased numbers of CD14+CD163-, CD14+CD163-MAC387+ M1 monocytes, but significantly reduced numbers of CD14+CD163+IL-10+ M2 monocytes were detected in the MAP patients(P < 0.01 or P < 0.05). Furthermore, significantly higher levels of plasma IL-10 and IL-12 were observed in the MAP patients(P < 0.01 for all). More importantly, the levels of plasma CRP were positively correlated with the numbers of CD14+CD163-(R = 0.5009, P = 0.0127) and CD14+CD163-MAC387+(R = 0.5079, P = 0.0113) M1 monocytes and CD14+CD163+CD115+ M2 monocytes(R = 0.4565, P = 0.0249) in the patients. The APACHE II scores correlated with the numbers of CD14+CD163+CD115+(R = 0.4581, P = 0.0244) monocytes and the levels of plasma IL-10(R = 0.4178, P = 0.0422) in the MAP patients. However, there was no significant association among other measures tested in this population. CONCLUSION Increased numbers of CD14+CD163- and CD14+ CD163-MAC387+ monocytes may contribute to the pathogenesis of MAP, and increased numbers of CD14+CD163+CD115+ monocytes may be a biomarker for evaluating the severity of MAP.展开更多
