【Abstract】 Objective To study the association between -148C/T polymorphism of β-fibrinogen gene and plasma fibrinogen levels in young patients with acute cerebral infarction(ACI).Methods 69 young patients with ACI and 60 young healthy individuals were enrolled in this trial. The β-fibrinogen gene-148C/T polymorphism was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and plasma fibrinogen levels were obtained from prothrombin time assay.Results Plasma fibrinogen levels of the patients were significantly higher than those of the controls ( P<0.01). In both groups those with T allele had higher plasma fibrinogen levels than those without ( P>0.05), but there was no significant difference in T allele frequencies between the patients and the controls ( P>0.05).Conclusions Plasma fibrinogen level is affected by -148C/T polymorphism of β-fibrinogen gene. High plasma fibrinogen level is a risk factor for ACI in Chinese young adults. With other risk factors and environmental factors, T allele increases plasma fibrinogen level and may be a heritable risk factor for ACI in Chinese young adults.更多还原
