RESUMEN
Objective To observe the mRNA and protein expression of SOCS-1 and SOCS-3 in the peripheral blood mononuclear cells(PBMCs) in patients with systemic inflammatory response syndrome(SIRS) and explore its clinical significance.Methods Peripheral blood of 20 patients with SIRS and 16 healthy people wag collected and the PBMCs were isolated by centrifugafion and Ficoll-Hypaque sedimentation.The mRNA of SOCS-1 and SOCS-3 was determined by reverse transcription-polymerase chain reaction(RT-PCR).And the protein content of SOCS-1 and SOCS-3 was determined by Western Blotting.Results The SOCS-1 mRNA expression in the PBMCs of SIRS group (0.642±0.112) was significant higher than that of control group(0.458±0.044)(P<0.05).There was no significant difference between the PBMCs,SOCS-1 content of control group(0.488±0.019) and SIRS group (0.471±0.041).The SOCS-3 mRNA expression in the PBMCs of SIRS group(0.989±0.324) was higher than that control group(0.459±0.046)(P<0.05).There was no significant difference between the PBMCs'SOCS-3 content of control group(0.400±0.025) and SIRS group(0.426±0.015).Conclusions The mRNA expression of SOCS-1 and SOCS-3 in the PBMCs were higher in SIRS patients.The SOCS-1 and SOCS-3 may participate in the development of SIRS.
