摘　　要：目的运用静息态功能磁共振成像(rs-fMRI)方法,观察疏血通注射液联合西医常规疗法对急性缺血性脑卒中的疗效,以及大脑神经元活动比率低频振幅(fALFF)的变化,探讨其潜在的疗效机制。方法选择急性缺血性脑卒中患者及健康对照者各20例。患者行西医常规治疗,并予疏血通注射液6 mL加生理盐水250 mL静脉滴注,每日1次,治疗14 d,随访至发病30 d。健康对照组无干预措施。随访时评价患者临床疗效。于治疗前、随访时评价患者美国国立卫生研究院卒中量表(NIHSS)、改良Rankin量表(mRS)、日常生活活动能力量表(BI)评分。于治疗前、随访时对患者行rs-fMRI,健康对照组行1次rs-fMRI,比较患者2次fALFF差异及与健康对照组的差异。结果临床疗效总有效率为95%(19/20)。随访时NIHSS、mRS评分明显降低,BI评分明显升高(P<0.01)。与健康对照组比较,患者治疗前左侧额中回和左侧顶下小叶fALFF值明显降低(P<0.05),患者随访时左侧额中回和右侧枕上回fALFF值明显降低(P<0.05);与治疗前比较,患者随访时左侧额中回fALFF值有增高趋势,但差异无统计学意义(P>0.05)。结论疏血通注射液联合西医常规疗法对急性缺血性脑卒中疗效显著,其机制可能是通过调节左侧额中回神经元内在活动实现。Objective To observe the clinical efficacy of Shuxuetong Injection combined with conventional therapy in the treatment of acute ischemic stroke by resting state functional magnetic resonance imaging(rs-fMRI);To explore the change of fractional amplitude of low-frequency fluctuation(fALFF);To reveal the potential therapeutic mechanism.Methods Totally 20 patients with acute ischemic stroke and 20 healthy persons were selected.The patients received conventional western medicine treatment,and were given 6 mL of Shuxuetong Injection and 250 mL of normal saline,intravenous drip,once a day,for 14 days,and followed up for 30 days.The healthy control group had no intervention.The clinical efficacy was evaluated during follow-up.The National Institutes of Health stroke scale(NIHSS),modified Rankin scale(mRS),and Barthel ADL index(BI)scores were evaluated before treatment and during follow-up.Before treatment and during follow-up,rs-fMRI was performed on patients,and rs-fMRI was performed on healthy control group once.The difference of fALFF between patients before treatment and during follow-up and the difference with healthy control group were compared.Results The total effective rate was 95%(19/20).During the follow-up,NIHSS and mRS scores significantly decreased,and BI score significantly increased(P<0.01).Compared with the healthy control group,the fALFF of the left middle frontal gyrus and left inferior parietal lobule of the patients significantly decreased before treatment(P<0.05),and the fALFF of the left middle frontal gyrus and the right superior occipital gyrus of the patients significantly decreased during the follow-up(P<0.05).Compared with before treatment,the fALFF value of left middle frontal gyrus of the patients showed an increasing trend during follow-up,without statistical significance(P>0.05).Conclusion Shuxuetong Injection combined with conventional therapy have evident clinical efficacy on acute ischemic stroke,and its efficacy mechanism may be achieved by regulating the intrinsic activity of neurons
