Objective To study the effect of apolipoprotein A5 gene polymorphism on the metabolic syndrome and cardiovascular events.Methods A total of 200 patients with metabolic syndrome include 100 cases of unconsolidated cardiovascular events (MS-1 group) and 100 cases of combined cardiovascular events (MS-2 group); 100 cases of healthy people were used as control group.Apolipoprotein A5 serum concentration was detected by ELISA in each group.PCR-RFLP method was used to determine ApoA5-1131T > C gene polymorphism.The automatic analyzer was used to measure fasting plasma glucose (FPG).Results The MS-1-group ApoA5 Serum concentration was significantly lower than the control group [(96.68 ± 18.09) ng/ml vs (128.32 ±23.78) ng/ml,t =10.59,P <0.01] ; the MS 2 groups ApoA5 serum concentrations was significantly lower than the MS-1 group [(87.67 ± 17.09) ng/rnl vs (96.68 ±18.09) ng/ml,t =3.62,P <0.01] ; and ApoA5-1131C genotype frequency in MS-2 group and the MS-1 group was significantly higher than the control group (39.4% > 30% > 16.5%,P < 0.05).Conclusions ApoA5 serum concentrations in patients with metabolic syndrome and cardiovascular events were significantly reduced,ApoA5-1131 C was related to the metabolic syndrome and cardiovascular events.

Objective To explore the relationship between metabolic syndrome and ApoA5 gene polymorphism and serum concentration. Methods 100 patients with metabolic syndrome(MS group) and 100 healthy people(control group) were enrolled in this study. The ApoA5 serum concentration of two groups were measured by using enzyme-linked immunosorbent assay(ELISA), the genotypes of ApoA5-1131T>C polymorphism were analyzed by polymerase chain reaction-restriction fragment length polymorphism, and fasting blood glucose (FBG), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL) and white blood cell, hemoglobin,platelet, liver and kidney function were measured. Results MS group was compared with control group. In MS group, the ApoA5 serum concentration was significantly lower[(96.68±18.09)ng/ml vs (128.32±23.78)ng/ml,P<0.01], while the triglycerides levels were obviously higher[(2.35±1.07)mmol/L vs (1.62±1.13)mmol/L,P<0.01], and ApoA5-1131C allele frequency was higher than that in control group (30% vs 16.5%,P<0.05). Conclusions The ApoA5 serum concentration in metabolic syndrome was decreased, and ApoA5-1131C was associated with metabolic syndrome.
