Abstract:
Objective:To study relationship among serum homocysteine (Hcy) level ,paraoxonase 1 (PON1) activity and carotid atherosclerosis .Methods:A total of 179 residents from a community of Shanghai ,who participated in cardiovascular risk factor screening from 2012 to 2014 ,were selected .They received carotid ultrasonic examination and measurements of serum Hcy ,PON1 and other biomarkers .According to serum Hcy level ,subjects were divided into elevated Hcy group (n=85) and normal Hcy group (n=94) .Results:Spearman correlation analysis indicated that serum Hcy level was significant inversely correlated with PON1 activity (r= -0.738 ,P=0.001) .Compared with normal Hcy group ,there were signifi‐cant rise in age [(60.66 ± 7.18) years vs .(64.57 ± 7.29) years] ,male proportion (27.66% vs .63.53% ) ,serum creati‐nine [(69.62 ± 12.76)μmol/L vs .(88.47 ± 20.86)μmol/L] ,uric acid [(267.85 ± 63.02)μmol/L vs .(307.51 ± 76.07)μmol/L] ,triglyceride [(1.33 ± 0.79) mmol/L vs .(1.76 ± 1.70) mmol/L]and systolic blood pressure [(134.93 ± 15.82) mmHg vs .(142.72 ± 17.86) mmHg] ,and significant reductions in levels of high density lipoprotein cholesterol [HDL‐C , (1.17 ± 0.26) mmol/L vs .(1.06 ± 0.27) mmol/L]and PON1 [(288.58 ± 73.80) kU/L vs .(187.81 ± 16.31) kU/L]in el‐evated Hcy group , P<0. 05 or <0. 01. Incidence rate of carotid atherosclerosis in elevated Hcy group was significantly higher than that of normal Hcy group (64. 7% vs .44. 7% ) , P=0. 001 .Multi‐variate gradual Logistic regression analysis indicated that serum creatinine and Hcy levels were independent risk factors for serum PON 1 activity(OR=1.055 ,1.139 , P<0.01 ,<0.05);Hcy isn′t an independent risk factor (OR=1.020 ,P=0.497) for carotid atherosclerosis .Conclusion:Serum Hcy level is significant inversely correlated with serum PON 1 activity ,and both of them are related to occurrence of carotid atherosclerosis .
