PAS三联疗法对急性脑梗死患者血脂、血清sCD40L及MMP-9水平及颈动脉易损斑块稳定性的影响

目的 探讨普罗布考、阿司匹林、他汀类药物(PAS)三联疗法对急性脑梗死患者血脂、血清超敏C-反应蛋白(hs-CRP)、可溶性CD40配体(sCD40L)及基质金属蛋白酶-9(MMP-9)水平的影响,观察其对颈动脉易损斑块稳定性的影响.方法 根据颈动脉超声检查结果分为颈动脉稳定斑块组(n=45)和颈动脉易损斑块组(n=90).将稳定斑块组作为对照组,按随机数字法将易损斑块组分为AS组(n=45,阿司匹林100mg/d,阿托伐他汀20mg/d,口服)和PAS组(n=45,AS基础上加用普罗布考片,0.25/次,2次/日,口服).比较治疗前后血脂、血清hs-CRP、sCD40L和MMP-9水平；观察治疗前后颈动脉内-中膜厚度(IMT值)、斑块Crous积分及斑块回声变化.结果 治疗后4w,两组中TG、TC、LDL-C、血清hs-CRP、sCD40L和MMP-9水平均下降,PAS组中各项指标下降幅度均大于AS组,差异具有显著性(P均＜0.01)；治疗后12个月,两组IMT值和斑块Crous积分较治疗前减少,且PAS组两项指标低于AS组,PAS组低回声斑块回声增强例数高于AS组(P均＜0.01).结论 PAS三联疗法是一种安全有效的治疗方法,具有更强的降脂抗炎作用,可逆转和稳定斑块.

Effect of PAS therapy on blood lipoprotein,serum soluble CD40 ligand and marix metalloproteinase-9(MMP-9) in patients with acute cerebral infarction and the stability of carotid vulnerable plaque

Objective To observe the influence of combination therapy of probucol,aspirin and statins drugs(PAS) on levels of blood lipoprotein,high sensitivity C-reactive protein(hs-CRP),soluble CD40 ligand(sCD40L) and marix metalloproteinase-9(MMP-9) in patients with acute cerebral infarction(ACI) and its effect on the stability of carotid artery plaque.Methods According to the results of carotid artery ultrasound,135 cases of patients with ACI were divided into carotid stable plaque group(n=45) and carotid vulnerabl...
