Abstract:
Objective To observe the influence of combination therapy ofprobucol,aspirin and statins drugs (PAS) on levels of serum oxidized low-density lipoproteins (ox-LDL),pregnancy-associated plasma protein A(PAPP-A) and marix metalloproteinase-3(MMP-3) and resolution of carotid vulnerable plaque in patients with acute cerebral infarction (ACI).Methods One hundred and thirty-five patients with ACI,admitted to our hospital from September 2007 to July 2010,were chosen in our study; according to the results of carotid artery ultrasound,these patients were divided into carotid stable plaque group (n=45) and carotid vulnerable plaque group (n=90).Stable plaque group was considered as control group; 90 patients with carotid vulnerable plaque were randomly subdivided into aspirin and statins drugs (AS) group (n=45,aspirin 100 mg/d,atorvastatin 20 mg/d,orally) and PAS group (n=45,aspirin 100 mg/d,atorvastatin 20 mg/d,probucol 0.25 g/time,2 times/day,orally).Levels ofOx-LDL,PAPP-A and MMP-3 were detected in all patients before treatment and four weeks after drug therapy.The intima-media thickness,plaque area and echogenicity of carotid plaques were evaluated by Doppler ultrasonography during a 12-month follow-up period.Results Before treatment,serum ox-LDL,PAPP-A and MMP-3 levels in AS group and PAS group were significantly higher than those in the control group (P＜0.05); no significant differences of ox-LDL,PAPP-A and MMP-3 levels were noted between AS and PAS groups (P＞0.05).Four weeks after treatment,levels of serum ox-LDL,PAPP-A and MMP-3 in PAS group were significantly lower than those in AS and control groups (P＜0.05); the decrease of levels of ox-LDL,PAPP-A and MMP-3 in PAS group was obviously higher than that in AS and control groups (P＜0.05).Twelve months after treatment,significant decrease of plaque area and intima-media thickness (IMT) was noted in the AS and PAS groups (P＜0.05); the IMT and plaque area in PAS group were significantly smaller than those in AS group (P＜0.05); obvious decrease of echogenicity of carotid plaques in PAS group was noted as compared with that in AS group (P＜0.05).Conclusion Combination therapy of PAS might have strong anti-oxidant function and lipid-lowering effect,which could reverse and stabilize the atherosclerosis plaque.
