Abstract:
Objective To investigate the level change of glucose excursion , 8-iso prostaglandin F 2α( 8-iso-PGF2α) in type 2 diabetes mellitus(T2DM), and its effects on nonalcoholic fatty liver disease (NAFLD).Methods A total of 62 inpatients with type 2 diabetes mellitus including T2DM group(DM, 30 cases) and T2DM with NAFLD group(DM+NAFLD, 32 cases) were recruited from October 2012 to November 2013 , normal glucose tolerance group had normal glucose tolerance ( NGT;30 cases ) with normal physical examination results.The age, gender, duration, blood pressure, body mass index (BMI), and blood lipid among three groups were no statistical difference .The clinical data of each patient were collected by professional people .Blood lipids and glycated hemoglobin (HbA1c) were detected.Oral glucose tolerance test (OGTT) were taken in all groups.The Postprandial glucose excursion (PPGE), blood glucose standard deviation (SDBG), mean blood glucose and (MBG) and HbA1c were used to evaluate the glucose excursion.Serum 8-iso-PGF2αwas detected by enzyme-linked immunosorbent (ELISA) to evaluate oxidative stress.Inter-group com-parison was conducted with analysis of variance ( ANOVA) .Correlation analysis was used to evaluate the factors of influence .Results⑴The levels of PPGE[(7.34 ±2.23) mmol/L vs (8.52 ±2.43) mmol/L],SDBG[(2.43 ±0.90) mmol/L vs (2.80 ±0.78) mmol/L], MBG[(11.06 ±1.76) mmol/L vs (13.65 ±2.83) mmol/L], and HbA1c [(7.59 ±1.02)% vs (8.05 ±1.52)%] in T2DM group and T2DM with NAFLD group were significantly higher than that in NGT group (both P <0.05); and that in NAFLD group have significantly rise than that in DM group ( P <0.05), but there was no significant difference in HbA 1c between groups.⑵ The level of serum 8-iso-PGF2αwas gradually increased from NGT group [(33.45 ±8.60) pg/ml], DM group [(47.33 ±15.30) pg/ml], to DM +NAFLD group [(56.07 ±13.10) pg/ml], with statistically significant difference ( P <0.05);⑶The Person corre-lation analysis showed that the content of serum 8-iso-PGF2αwas positively correlated with PPGE, SDBG, and MBG ( r =0.796, 0.778 , 0.712 , P <0.01 ) .Conclusions Serum 8-iso-PGF2αis a better parameter to reflect the status of body oxidative stress .The level of oxidative stress is increased with the increase of glucose excursion in T 2DM, which is the important mechanism of its complica-tions of NAFLD.
