Influence of apolipoprotein E gene polymorphism on the lipid regulation by xuezhikang capsule / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the influence of apolipoprotein E (ApoE) gene polymorphism on the lipid metabolism regulatory effect of Xuezhikang Capsule (XZKC).</p><p><b>METHODS</b>ApoE polymorphism of 74 patients with hyperlipidemia was detected by gene sequencing method, and their plasma levels of total cholesterol (TC), triglyceride (TG), high- and low-density lipoprotein cholesterol (HDL-C and LDL-C) were determined before and after they received a 6-week treatment of XZKC, for analyzing the relationship between ApoE gene polymorphism and the changes of various blood lipids associated indices.</p><p><b>RESULTS</b>The effect of XZKC on reducing TG in the epsilon2 allele (E2/E2 and E2/E3 genotypes) was higher than that in the E3/E3 genotypes and epsilon4 allele (E3/E4 and E4/E4 genotypes), while on increasing HDL-C, it showed more effect in the epsilon4 allele (E3/E4 and E4/E4 genotypes) than that in the epsilon2 allele (E2/E2 and E2/E3 genotypes) and E3/E3 genotypes.</p><p><b>CONCLUSION</b>Patients' ApoE gene polymorphism could influence the lipid regulatory effect of XZKC, embodying mainly by raising HDL-C and reducing TG in patients with different ApoE genotypes to different extents.</p>
