Abstract:

Objective To study the correlation of apopoprotein H(ApoH) gene single nucleotide polymorphisms(SNP)and carotid plaques in patients with ischemic cerebral stroke(ICS). Methods A total of 737 patients with ICS were enrolled from Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine and Department of Neurology of Central Hospital of Shanghai Minhang District. They were classified into carotid plaque group(431 cases) and non-carotid plaque group(306 cases)(control group). By multiple polymerase chain reaction(PCR) and sequence analysis,the genotype and allele frequencies of ApoH gene SNP loci(rs8178842,rs6933,rs4791079,rs2873966 and rs1801690) between the 2 groups were compared,and the relative risk was evaluated. Results In carotid plaque group,triglyceride(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),non-high-density lipoprotein cholesterol(non-HDL-C),systolic blood pressure and blood glucose were higher than those in control group(P<0.05). In carotid plaque group,rs4791079 locus CA and CA/AA genotype frequencies were 15.3% and 16.5%,which were higher than those in control group(8.8% and 8.8%)(P=0.008,P=0.022). In carotid plaque group,rs1801690 locus GC/CC genotype frequency was 8.8%,which was lower than that in control group(13.4%)(P=0.049). In carotid plaque group,rs4791079 locus A allele frequency(8.8%) was higher than that in control group(4.4%)(P=0.001). The relative risk analysis found that carrying A allele increased the risk of carotid plaque [odds ratio(OR)=2.095,95% confidence interval(CI)1.333-3.292]. In carotid plaque group,rs1801690 locus C allele frequency(4.4%)was lower than that in control group(7.0%)(P=0.030). The relative risk analysis found that carrying C allele decreased the risk of carotid plaque(OR=0.610,95%CI 0.389-0.956). Conclusions ApoH gene rs4791079 and rs1801690 loci have correlations with carotid plaques in patients with ICS.
