In addition, the levels of P-selectin and IL-12p70 were not significantly different among the GN-BSI, GP-BSI and fungal-BSI patients (P > .05), despite that previous studies have occasionally reported that P-selectin and IL-12p70 play an important role in the regulating immune activation and participating in inflammatory response when infection occurs.[36,37] Similar investigations of these factors need to be performed in the future. This evidence concerns the gene SELP and infection.
