摘要Objective: To explore the value of serum PCT content for evaluating inflammatory factor release and organ function injury in neonatal septicemia. Methods: 48 children who were diagnosed with neonatal septicemia in our hospital between March 2015 and May 2018 were selected as the septicemia group, and 50 healthy neonates delivered in our hospital during the same period were selected as the normal control group. The differences in PCT and inflammatory factor contents in serum as well as liver and kidney function index levels in peripheral blood were compared between the two groups. Pearson test was used to evaluate the correlation of serum PCT content with inflammatory factor release as well as liver and kidney function injury in children with neonatal septicemia. Results: The serum PCT content of septicemia group was significantly higher than that of normal control group; serum hypersensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), interleukin-8 (IL-8) and soluble intercellular adhesion molecule-1 (sICAM-1) contents were higher than those of normal control group; peripheral blood aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (γ-GGT) and alkaline phosphatase (ALP) levels were higher than those of normal control group; peripheral blood blood urea nitrogen (BUN), serum creatinine (Scr) and serum β2-microglobulin (β2-M) levels were higher than those of normal control group (P<0.05). Correlation analysis showed that serum PCT content in children with neonatal septicemia was directly correlated with the degree of inflammatory response as well as the degree of liver and kidney function injury (P<0.05). Conclusion: The serum PCT content abnormally increases in children with neonatal septicemia, and the specific content is consistent with the disease severity and has certain clinical value for the judgment of children's condition.
