ABSTRACT
Objective To analyze the plasma free fatty acid (FFA) composition in patients with T2DM. Methods All subjects were from Zhongnan hospital of Wuhan university, and they were divided into three groups normal control ( n = 94 ), T2DM ( n = 101 ) and T2DM with hyperlipidemia ( n = 77 ). Fasting blood samples were taken from the participants, and plasma FFA were separated using a modified Doles method with the bromoacetophenone, pre-column-derivative. The quantitation of FFA was performed on were (355.63 ± 100. 35) μmol/L, (421.21 ± 200. 83 ) μ mol/L, ( 473.04 ± 213.40 ) μmol/L in healthy controls, T2DM group and T2DM with hyperlipidemia group, respectively. The significant differences were observed among the 3 groups(x2 = 13.08, P <0.01 ). However, there was no significant difference of UFA concentrations among the 3 groups [(206.29± 61.94) μ mol/L, (218.11 ± 110.28) μmol/L and ( 240.94 ± 116.79 ) μmol/L, x2 = 2.17, P > 0.05]. Compared to normal control [( 355.63 ± 100.35 )μmol/L], the FFA concentration[(421.21 ±200.83) μmol/L] in T2DM has significantly increased (x2 =FFA concentrations were higher in T2DM with hyperlipidemia [(473.04 ±213.40) μmol/L] (x2 =27.93,P <0.01 ). The RSD values for intra- and inter-day precision were less than 5%, and the minimal detection limits ranged from 0.05 μmol/L to 0.35 μmol/L The recoveries of high, intermediate and low-level materials were 96.4% -104.8%. Conclusions The total FFA concentration in T2DM has increased, most of which are saturated FFA. The unsaturated FFA has not significantly increased. They seem to be related to the development of T2DM, and might be a new biomarker for clinical monitoring of metabolic disorder of T2DM.
