Abstract:
Objective To explore the correlation of serum level of reduced NOX2 with cerebral blood supply and prognosis in elderly patients with TBI.Methods A total of 86 elderly TBI pa-tients admitted to our department from January 2019 to December 2022 were recruited and served as the TBI group,and another 80 age-and gender-matched elderly individuals who took physical examinees in our hospital during the same period were enrolled and served as the control group.According to the GCS score at admission,the TBI group was divided into mild,moderate and se-vere subgroups(22,35 and 29 cases).The patients were also assigned into good prognosis sub-group(54 cases)and poor prognosis subgroup(32 cases)based on GOS score in 6 months after treatment.The dynamic changes in serum NOX2 level and cerebral blood flow indicators among different groups and subgroups were compared,and their correlation with the prognostic GOS score was analyzed.Results The average blood flow Vm,rCBF,and rCBV of TBI patients at 1,3,5,7,and 10 d after injury were significantly reduced,and the serum NOX2 level was obviously in-creased when compared to the control group(P＜0.01).Statistical difference was seen in serum NOX2 level among the patients with different degrees of TBI at 1,3,5,7 and 10 d after injury(P＜0.05,P＜0.01).The serum NOX2 level at 1,3,5,7,10 and 14 d after injury in the TBI group was negatively correlated with GCS score(r=-0.413,-0.427,-0.515,-0.592,-0.566,-0.338;P＜0.01),and the Vm CBV,and rCBF values at 1,3,5,7,and 10 d after injury were posi-tively correlated with GCS score(r=0.392,0.379,0.407,0.418,0.420,P＜0.01;r=0.404,0.414,0.429,0.419,0.428,P＜0.01;r=0.412,0.427,0.432,0.428,0.393,P＜0.01).The serum NOX2 level at 1,3,5,7 and 10 d after injury in the TBI group was negatively correlated with Vm,rCBV and rCBF values(P＜0.01).The serum NOX2 level of the patients in the poor prognosis subgroup were significantly higher than those in the good prognosis subgroup at 1,3,5,7,10,and 14 d after injury,while,the rCBV and rCBF values were obviously lower than those in the good prognosis subgroup(P＜0.05,P＜0.01).The serum NOX2 level in the TBI patients at 1,3,5,7,10,and 14 d after injury were negatively,while Vm,rCBV and rCBF values were positively correlated with GOS scores at 6 months after treatment(P＜0.01).Conclusion Elevated serum NOX2 level is closely correlated with insufficient cerebral blood supply and poor prognosis in elderly TBI pa-tients.Dynamic monitoring of serum NOX2 level and changes in cerebral blood flow indicators are of great clinical significance in evaluation of TBI prognosis.
