ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association of serum pigment epithelium-derived factor (PEDF) level and polymorphisms in PEDF gene promoter region -358G→A with non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus (T2DM) of Han Nationality in Fujian Province.</p><p><b>METHODS</b>A total of 282 T2DM patients with NAFLD (DM1 group) and 170 age- and gender-matched T2DM patients without NAFLD (DM2 group) were examined for PEDF gene SNP-358G→A polymorphisms using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Serum pigment epithelium-derived factor(PEDF) level, fasting plasma glucose (FPG), fasting insulin (FINS) and glycosylated hemoglobin (HbA1c) were also measured.</p><p><b>RESULTS</b>The patients in DM1 group showed a significantly higher mean level of serum PEDF than those in DM2 group (P<0.05). Logistic regression analysis revealed that PEDF level was an independent risk factor for NAFLD in T2DM. The frequencies of PEDF gene -358G→A genotypes (GG, GA, and AA) and alleles (G/A) differed significanly between DM1 and DM2 groups (P<0.05). In terms of PEDF gene SNP -358G→A alleles, the GA genotype carriers had a 2.032 times higher risk of developing NAFLD compared with the GG genotype carriers, and the risk increased to 2.068 times in the carriers of the A allele (GA and AA genotypes; P<0.05).</p><p><b>CONCLUSION</b>Serum PEDF level is an independent risk factor of NAFLD in T2DM. Elevated serum PEDF level is a protective factor against insulin resistance. In T2DM patients, PEDF gene promoter region -358G→A polymorphism is associated with NAFLD, and the A allele contributes to an increased risk of NAFLD.</p>

Risk factors of hyperamylasemia in 152 diabetic ketoacidosis(DKA)patients who had no acute pancreatitis were examined.Serum levels of hemodiastase,natrium,kalium,chlorine,calcium,phosphonium,creatinine,carbon dioxide combining power,osmotic pressure,blood glucose,blood lipids and uric acid were measured.With hemodiastase and other 14 factors as independent variables,the multiple linear regression analysis was performed and the partial regression coefficient was estimated.Blood glucose,serum natrium,osmotic pressure and triglyceride entered the regression equation,and their partial coefficients were 10.26,10.35,2.21 and 8.00,respectively.The constant quantitv was -2162.06.Compared with amylase-normal group,hyperamylasemia group showed statistically significant difference in blood glucose,serum natrium,osmotic pressure and triglyceride levels.Higher blood glucose and triglyceride might be the primary causes of hyperamylasemia.
