Differential expression analysis of coronary heart disease related genes in Hainan residents.

Objective: To explore the correlation between coronary heart disease related genes and coronary heart disease in hospitalized patients in Hainan, and to provide theoretical basis for enriching the screening methods of high-risk groups of coronary heart disease in Hainan, and optimizing the prevention and treatment strategies. Methods: We select hospitalized patients born in Hainan and aged >30 years old from the Second Affiliated Hospital of Hainan Medical Unversity between January 1, 2020 and June 30, 2022, and divided the patients into the coronary heart disease group and the non-coronary heart disease group. PCR real-time fluorescence was used to measure gene expression, and Spearman correlation analysis was used to explore the correlation between gene expression and coronary heart disease. Results: A total of 55 whole blood samples were collected from non-coronary heart disease patients (including 26 women and 29 men), with a median age of 57 years, and 170 whole blood samples from coronary heart disease patients (including 44 women and 126 men), with a median age of 63.17. Apolipoprotein B gene (ApoB) was highly expressed in patients with coronary heart disease (P<0.001); AGT gene (P=0.015 8), ApoE gene (P=0.012 6), FGB gene (P=0.005), GNB gene (P=0.015 1), MTFHR gene (P=0.011 9), SEL gene (P=0.005), TNF gene (P=0.029 8) were significantly overexpressed in the non-coronary heart disease group. The expression of NOS3 gene (P=0.304 7), IL6 gene (P=0.723 9), ACE gene (P=0.785 2)was not different between the two groups. Coronary heart disease was negatively correlated with AGT gene (r=-0.163, P=0.011, P<0.05), positively correlated with APOB gene(r=0.75, P=0, P<0.01), negatively correlated with FGB gene(r=-0.163, P=0.011, P<0.05), negatively correlated with GNB gene(r=-0.165, P=0.011, P<0.05), negatively correlated withSEL gene(r=-0.171, P=0.007, P<0.01), negatively correlated with MHTHR gene(r=-0.210, P=0.001, P<0.01) and negatively correlated with TNF gene(r=-0.131, P=0.04, P<0.05), but coronary heart disease was not correlated with APOE, NOS3, ACE, IL6 and other genes (P>0.05). The ApoB gene of coronary heart disease was negatively correlated with triglyceride (r=-0.461, P=0), positively correlated with age (r=0.173, P=0.009), positively correlated with total cholesterol (r=0.499, P=0), negatively correlated with high-density lipoprotein (r=-0.181, P=0.007), and negatively correlated with low-density lipoprotein (r=-0.143, P=0.031). Conclusion: (1) The detection of apolipoprotein B gene expression may be used as an indicator for screening coronary heart disease in the coronary population in Hainan. It may increase the risk of coronary heart disease by affecting the level of total cholesterol. A larger sample of research is still needed.(2) AGT,ApoE, FGB, GNB, MTFHR, SELE, TNF and other genes may be the protective genes of non-coronary heart disease population in Hainan, and the high expression of these genes may reduce the occurrence of coronary heart disease, which still needs further study.
