| Sumario: | Yanmin Song, Qunfang Li, Lili Long, Ning Zhang, Yunhai Liu Department of Neurology, Xiangya Hospital, Central South University, Changsha, Hunan Province, People’s Republic of China Background: CD31, also called platelet endothelial cell adhesion molecule-1 (PECAM-1), is thought to play a role in the pathological mechanisms of atherosclerosis. Leu125Val polymorphism and elevated plasma levels of soluble PECAM-1 (sPECAM-1) were found to be associated with cerebral infarction. Our aim was to investigate the association between the Asn563Ser polymorphism of CD31/PECAM-1, plasma level of sPECAM-1, and the risk of atherosclerotic cerebral infarction (ACI) in the southern Han population of the People’s Republic of China.Subjects and methods: A total of 147 subjects with ACI and 114 controls were enrolled in the study. The Asn563Ser CD31/PECAM-1 polymorphism was detected using the polymerase chain reaction–restriction fragment length polymorphism method. The plasma spECAM-1 level was measured using the enzyme-linked immunosorbent assay method.Results: In this study, statistically significant differences in Asn563Ser genotype and allele distribution were found between the cases and controls (P<0.05). Furthermore, logistic regression analysis showed that the GG genotype is associated with increase in ACI risk (odds ratio =4.862, P<0.001). The plasma level of sPECAM-1 was associated with ACI (odds ratio =1.431, P=0.038). In both the ACI and the control groups, the plasma sPECAM-1 level in subjects with the GG genotype was higher than that in subjects carrying the AA or GA genotype (P<0.05).Conclusion: Our study showed that the Asn563Ser polymorphism of CD31/PECAM-1 gene and elevated plasma sPECAM-1 level are related to ACI risk in the southern Han population of People’s Republic of China.
