摘要 目的观察颈动脉粥样硬化患者外周血辅助性T淋巴细胞17(Th17)、调节性T细胞(Treg)数量变化,探讨阿托伐他汀干预对Th17、Treg的影响。方法选取颈动脉粥样硬化患者80例,随机分为阿托伐他汀组和常规治疗组各40例;另选同期体检健康者40例作为健康组。阿托伐他汀组和常规治疗组均积极控制基础疾病,阿托伐他汀组再口服阿托伐他汀钙片(立普妥)40 mg/d,两组均连续治疗3个月。阿托伐他汀组及常规治疗组于治疗前及治疗3个月结束时,健康组于体检时,分别采集空腹静脉血,采用流式细胞仪检测Th17、Treg数量,计算Th17、Treg比例及Treg/Th17;采用RT-PCR法检测血浆维甲酸受体相关的孤儿受体(ROR-γt)、叉头翼螺旋转录因子(Foxp3)mRNA表达;采用ELISA法检测血清IL-17、转化生长因子β(TGF-β)。结果治疗前阿托伐他汀组与常规治疗组外周血淋巴细胞Th17比例、血浆ROR-γt mRNA相对表达量、血清IL-17水平均高于健康组,Treg比例、Treg/Th17及Foxp3 mRNA相对表达量、血清TGF-β水平均低于健康组(P均<0.05),阿托伐他汀组与常规治疗组间上述指标比较差异均无统计学意义(P均>0.05);治疗后,阿托伐他汀组Th17比例、血浆ROR-γt mRNA相对表达量、血清IL-17数量均较治疗前及常规治疗组治疗后降低,Treg比例及Treg/Th17、Foxp3 mRNA相对表达量、血清TGF-β水平较治疗前及常规治疗组治疗后升高,组间及组内比较P均<0.05。结论颈动脉粥样硬化患者外周血Th17数量增加、Treg数量减少,存在Th17/Treg失衡;阿托伐他汀治疗有助于纠正Th17/Treg失衡。
