The relationship between apolipoprotein E gene polymorphism and essential hypertension and the analysis of the efficacy of nanotechnology

The study aimed to detect the genetic polymorphism of apolipoprotein E (Apo E) in residents of Guizhou, China, explore its relationship with essential hypertension, and discuss the efficacy of nanotechnology in the treatment of hypertension. A total of 200 people in Guizhou, China were detected with Apo E polymorphisms and were divided into groups, The experimental group consists of people with essential hypertension and the control group of normal people. The SPSS 26.0 software was used to determine the correlation between Apo E gene polymorphisms and the essential hypertension risk. Logistic regression analysis was adopted to determine the risk factors of the Apo E gene for essential hypertension. Magnetic nanoparticles are used to help extract DNA, improve efficiency, and analyze the distribution of alleles in the population. The distribution frequencies of the six genotypes of E2/2, E2/3, E3/3, E3/4, E2/4, and E4/4 were 1.0%, 15.5%, 64.0%, 17.0%, 1.5%, and 1.0%, respectively, and the distribution frequencies of the three alleles of ε2, ε3, and ε4 were 9.5%, 80.3%, and 10.3%, respectively. There are more Apo E gene ε4 carriers in the experimental group than the control group, and the difference was statistically significant (P <0.05). The Apo E ε4 allele carriers had higher low-density lipoprotein and Apo B levels than the Apo E ε3 and Apo E ε2 gene carriers. Family history of hypertension and Apo E ε4 were both the main risk factors for essential hypertension. This study investigated the relationship between apolipoprotein E gene polymorphism and essential hypertension, and extracted DNA by magnetic nanoparticles to help analyze the distribution of alleles in hypertension population, which could provide theoretical basis for the diagnosis and treatment of essential hypertension in Guizhou Province, China.
