RESUMO
Objective To estimate the relationships between lipoprotein-associated phospholipase A2 (Lp-PLA2) activity and cerebral feeding artery athemsclemsis.Methods The blood samples were obtained from 148 atheroselerosis patients (atheroselerosis group) and 40 normal controls (control group).Activity of plasma Lp-PLA2 and traditional factors were determined.Logistic and regression model was adopted to analyze the roles of Lp-PLA2 and generally inflammatory risk factors in athemselemsis.Results Lp-PLA2 activity was significantly higher in atheroselerosis group than that in control group [(29.84±3.50)lesion number showed positive correlation with Lp-PLA2 (r=0.491,P＜0.01 and r=0.249,P=0.026).Adjusted other risk factors,Lp-PLA2 was an independent risk factor in cerebral feeding artery atherosclerosis.Conclusion Lp-PLA2,a novel inflammatory marker,is an independent risk factor of cerebral feeding artery atherosclerosis.
RESUMO
Objective To study the relationship between angiotensin converting enzyme (ACE)gene polymorphism and the risk factors of Binswanger's disease (BD) in Chinese Han nationality.Methods ACE gene insertion/deletion(ID) polymorphism in 111 Chinese Han Nationality patients with BD, 98 patients with hypertension and 102 normal controls were detected by polymorase chain reaction (PCR) technology,serum ACE was measured by colorimetric method,the risk factors of BD and family histories were assessed.Results The DD genotype frequency(0.64) was higher in BD group than in hypertension group (0.31, P
