Expression of triggering receptor on myeloid cell 1 and histocompatibility complex molecules in sepsis and major abdominal surgery

Figure 1 TREM-1 and HLA-DR expression in healthy volunteers and septic patients. Comparison of expression levels of TREM-1 (mean of fluorescence intensity) and HLA-DR (percentage of CD14+HLA-DR+cells) between healthy volunteers (H) and septic patients (S). ^aP<0.05 healthy vs septic for HLA-DR expression, ^cP<0.05 healthy vs septic for TREM-1 expression.

Figure 2 TREM-1 and HLA-DR expression in surgical patients. Comparison of expression levels of TREM-1 (mean of fluorescence intensity) and HLA-DR (percentage of CD14+HLA-DR+cells) in surgical patients before (BS) and after surgery (AS). ^aP<0.05 before surgery vs after surgery for TREM-1.

Figure 3 mRNA expression of svTREM-1. A: Expression index of svTREM-1/β-actin in each group. ^aP<0.05 healthy vs septic groups, ^cP<0.05 surgical (after surgery) vs septic groups; B: Representative svTREM-1 PCR products from healthy volunteers (H), surgical patients after surgery (AS) and septic patients (S).

Figure 4 Serum interleukin-6 levels. Serum levels of IL-6 in healthy volunteers (H), surgical patients before surgery (BS) and after surgery (AS), and septic patients (S). ^aP<0.05 healthy vs septic groups; ^cP<0.05 surgical groups before vs after surgery; ^eP<0.05 before surgery vs septic groups; ^gP<0.05 after surgery vs septic groups.
