Abstract:
Objective To explore the correlation between insulin resistance,inflammation factors and cognitive dysfunction in patients with metabolic syndrome (MS).Methods 150 cases of patients with MS were chosen,and they were divided into group A1 (n=68) and group A2 (n=82) according to whether they were with mild cognitive dysfunction (MCI).50 healthy cases chosen from physical examination were set as group B.The general data,laboratory examination results and inflammatory factor levels were compared between each group.MCI was set as dependent variable,insulin sensitivity index(ISI),high sensitive C-reactive protein(hs-CRP),and tumor necrosis factor-α(TNF-α) were set as independent variables.The relationship between inflammatory factor,insulin resistance and MCI was analyzed with multiple factors logistic regression analysis.Results The difference of body mass index(BMI),total cholesterol (TC),triglyceride (TG),low density lipoprotein (LDL),highdensity lipoprotein (HDL),fasting blood glucose(FBG),hemoglobin A1c (HbA1c),fasting insulin (FINS),and ISI between the three groups had statistical significance (P＜0.05).The levels of HbAlc in group A1 and group A2 were significantly higher than those in group B (P＜0.05).FBG and FINS showed a trend of reduce among the three groups,while ISI showed a trend of increase.The difference had statistical significance between each group (P＜0.05).The difference of hs-CRP,TNF-α between the three groups had statistical significance (P＜0.05).Levels of hs-CRP and TNF-α in group A1 were significantly higher than those in group A2 and group B,while the levels of hs-CRP and TNF-α in A2 group was significantly higher than those in group B (P＜0.05).Point biserial correlation analysis showed that the risk of MCI for MS patients had positive correlation with FBG,FINS,hs-CRP and TNF-α(r=0.219,0.231,0.309 and 0.287,P＜0.05),while it had negative correlation(r=-0.294,P＜0.05) with ISI.Multiariable logistic regression analysis showed that the more severe of insulin resistance (the lower ISI),the higher of inflammatory factor hs-CRP and TN-o,the greater the risk of MCI in patients with MS.Conclusion Insulin resistance and inflammation degree are more obvious in patients with MS combined with MCI,which can predict risk of cognitive dysfunction in patients with MS.
