Abstract:
Objective To investigate the expression pattern of resistin in subcutaneous adipose tissue and its effect on glycometabolism in rats with traumatic brain injury (TBI).Methods Fifty-six SD rats were randomly divided into TBI group (n =48) and control group (n =8) according to the random number table.mRNA and protein expressions of resistin in subcutaneous adipose tissue were detected with real-time PCR and Western-blot.Concentrations of serum insulin and serum fasting blood glucose were evaluated using the ELISA method and quantitative estimation of insulin sensitivity was performed.Indices measured and their correlations were statistically analyzed.Results Levels of the resistin,serum insulin and FBG were significantly higher in TBI group than in control group (P ＜ 0.05).Quantitative estimation of insulin sensitivity lowered in TBI group compared to control group (P ＜ 0.05).Single factor linear correlation analysis showed negative correlation between resistin expression and quantitative insulin sensitivity check index in TBI group (P ＜ 0.05).Conclusions Resistin is shown to have significant expression in subcutaneous adipose tissue and involve in glycometabolism.Obviously,resistin may play a significant role in insulin resistance after TBI in rats.
