The present study shows a close relationship between H. pylori infection and IM, and between IM and the development of gastric cancer. In addition, our finding suggests that chronic H. pylori infection looks like an important risk factor for the development of gastric cancer in Korea, where the prevalence of H. pylori remains high. This study indicates that to prevent gastric cancer H. pylori eradication is best performed before the development of IM.

Background:Menopause is an independent risk factor in metabolic syndrome which induced an alteration of the lipid metabolism by hormonal changes. Apolipoprotein A5 gene (APOA5) was related to the regulation of triglyceride and high density lipoprotein cholesterol (HDL-C) level with biosynthesis and decomposition. This study was conducted to investigate the relationship between APOA5 polymorphism and metabolic syndrome in Korean postmenopausal women. Methods: This study included 307 postmenopausal women with anthropometric and biochemical measurement in 2010-2011. The polymorphism of APOA5 was analyzed by polymerase chain reaction-restriction fragment length polymorphism method with MseI restriction enzyme. Results: The metabolic syndrome prevalence with TT genotype was significantly lower than the frequency in those with TC/CC (27.09%, 38.46%, and 45.71% for TT, TC, and CC, respectively; P < 0.05). Multiple regression analysis of metabolic syndrome risk factors indicated that postmenopausal women with CC genotype had a higher risk with 3 times than that in TT genotype (P < 0.05). APOA5 C carriers showed an increased risk of triglyceride level (odd ratio, 2.93 and 1.85 for CC and TC+CC, respectively; P < 0.05). Interestingly, HDL-C was related to triglyceride directly in comparison to APOA5. Conclusion:The results of this study indicate that APOA5 has an influence on serum triglyceride and HDL-C, which contribute to metabolic syndrome in Korean postmenopausal women.
