Objective: To study the correlation of serum GFAP, S100B and NSE contents with posttraumatic oxidative stress response and insulin resistance in patients with traumatic brain injury. Methods: A total of 110 patients with traumatic brain injury who were treated in our hospital between January 2015 and December 2016 were collected as the observation group, and 60 healthy subjects who received physical examination in our hospital during the same period were collected as normal control group. Serum GFAP, S100B and NSE levels as well as oxidative stress index and insulin resistance index levels of two groups of subjects were detected, and Pearson test was used to further evaluate the correlation of serum GFAP, S100B and NSE contents with oxidative stress response and insulin resistance in patients with traumatic brain injury. Results: Serum GFAP, S100B and NSE contents of observation group were significantly higher than those of normal control group; serum oxidative stress indexes MDA, MPO and LPO contents were higher than those of normal control group while SOD and TAC contents were lower than those of normal control group; serum insulin resistance indexes GLU, INS and HOMA-IR levels were higher than those of control group. Pearson test showed that serum GFAP, S100B and NSE contents in patients with traumatic brain injury were directly correlated with post-traumatic oxidative stress and insulin resistance. Conclusion: The serum GFAP, S100B and NSE contents increase in patients with traumatic brain injury, and the increase is directly correlated with the oxidative stress and insulin resistance.
