Effect of different blood glucose levels on viscera injury, oxidative stress response and Wnt5a inflammatory pathway in children with sepsis

摘要

Objective:To investigate the effect of different blood glucose levels on viscera injury, oxidative stress response and Wnt5a inflammatory pathway in children with sepsis.Methods:70 children with sepsis treated in our hospital between January 2014 and December 2015 were retrospectively collected and divided into the sepsis group A (blood glucose>10 mmol/L) (n=29) and the sepsis group B (blood glucose ≤10 mmol/L) (n=41) according to the different blood glucose levels, and 50 healthy children who accepted vaccination and were with normal blood glucose levels in our hospital during the same period were selected as healthy control group. The day after admission, RIA method was used to determine liver function indexes;automatic biochemical analyzer was used to determine oxidative stress indexes;enzyme-linked immunosorbent assay (ELISA) was used to detect Wnt5a inflammatory pathway index levels.Results: Liver function indexes total bilirubin (TBIL), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels of sepsis group A were higher than those of sepsis group B and healthy control group (P<0.05);oxidative stress indexes advanced protein oxidation products (AOPPs), lipid hydrogen peroxide (LHP), reactive oxygen species (ROS), and malondialdehyde (MDA) levels were higher than those of sepsis group B and healthy control group while glutathione peroxidase (GSH-Px) level was lower than that of sepsis group B and healthy control group (P<0.05);serum Wnt5a inflammatory pathway indexes interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-12 (IL-12) and macrophage inflammatory protein-1β (MIP-1β) levels were higher than those of sepsis group B and healthy control group (P<0.05).Conclusions:Sepsis children with high blood glucose are with severe liver function damage as well as intense oxidative stress and inflammatory response, which are the important indexes for severe illness and poor prognosis.
