目的 采用磁共振弥散张量成像(diffusion tensor imaging,DTI)观察针刺治疗前后孤独症谱系障碍(autism spectrum disorder,ASD)患儿脑白质微观结构的变化,以探索针刺在ASD中应用价值及DTI在评估针刺效果中作用.材料与方法 前瞻性纳入2021年11月至2022年10月在我院确诊的ASD患儿,按照随机数字表法分为针刺组和假针刺组,进行12周的干预治疗,于治疗前(第0周)及治疗后(第12周)行儿童孤独症评定量表(Child Autism Rating Scale,CARS)、孤独症儿童行为量表(Autism Behavior Checklist,ABC)、孤独症疗效评价量表(Autism Treatment Evaluation Checklist,ATEC)及DTI检查.比较两组间各项量表评分变化,采用基于纤维束示踪的空间统计方法(tract-based spatial statistics,TBSS)分析两组间脑白质各向异性分数(fractional anisotropy,FA)的差异,继而比较FA有差异脑区的平均弥散率(mean diffusivity,MD)、径向弥散系数(radial diffusivity,RD)和轴向弥散系数(axial diffusivity,AD)的不同及量表评分与DTI参数相关性.结果 与假针刺组相比,治疗后针刺组各项量表评分较治疗前显著降低,差异具有统计学意义(P<0.05).治疗后两组间FA值差异具有统计学意义(P<0.05),RD值差异无统计学意义(P>0.05),AD值两组间在左下纵束差异有统计学意义(P<0.05).相关性分析发现:ASD患儿ATEC评分与右扣带回的FA值呈负相关,与右额枕下束、右下纵束、右扣带回的RD值呈正相关,与右扣带回的AD值呈正相关;CARS评分与右扣带回的AD值呈正相关(P<0.05).右下纵束的FA值与ASD患儿的语言问题、感知觉异常呈负相关,RD值与社交障碍、感知觉异常呈正相关;右扣带回的FA值与语言问题、社交障碍、感知觉异常呈负相关,而RD值与上述临床症状呈正相关,AD值与社交障碍、健康问题呈正相关;双侧额枕下束FA值与感知觉异常存在负相关,右额枕下束RD值与其社交障碍、感知觉异常呈正相关;右上纵束的RD值与感知觉异常呈正相关;左丘脑前辐射束的AD值与感知觉异常呈正相关(P<0.05).结论 针刺可能通过促进脑白质纤维束完整性增强,从而改善ASD患儿临床症状,尤其在言语、社交、感知觉、健康问题等方面,进而说明DTI在评估针刺治疗效果中具有重要价值.
Evaluation of the therapeutic efficacy of acupuncture in children with autism using DTI
Objective:Using diffusion tensor imaging(DTI)to observe the changes in the microstructure of white matter in children with autism spectrum disorder(ASD)before and after acupuncture treatment,in order to explore the value of acupuncture in treating ASD and the role of DTI in evaluating the effectiveness of acupuncture.Materials and Methods:Prospective inclusion of children diagnosed with ASD in our hospital from November 2021 to October 2022,randomized using a random number table into an acupuncture group or a sham acupuncture group,for 12 weeks of intervention.Before treatment(week 0)and after treatment(week 12),the Child Autism Rating Scale(CARS),Autism Behavior Checklist(ABC),Autism Treatment Evaluation Checklist(ATEC)and DTI examination were performed.The changes in scores of various scales between the two groups were compared,and the tract-based spatial statistics(TBSS)was used to analyze the differences in fractional anisotropy(FA)of white matter between the two groups.Then compare the differences in mean diffusivity(MD),radial diffusivity(RD),and axial diffusivity(AD)of brain regions with varying fractional anisotropy(FA),and explore the correlations between scale ratings and DTI parameters.Results:Compared to the sham acupuncture group,the acupuncture group showed a significant decrease in various scale scores after treatment,and the difference was statistically significant(P<0.05).There was a statistically significant difference in FA values between the two groups after treatment(P<0.05),but no significant difference in RD values(P>0.05).In terms of AD values,there was a statistically significant difference between the two groups in the left inferior longitudinal fasciculus(P<0.05).The correlation analysis revealed in children with ASD,the ATEC scores were negatively correlated with the FA values of the right uncinate fasciculus,positively correlated with the RD values of the right infero-frontal-occipital fasciculus,right inferior longitudinal fasciculus,and right uncinate fasciculus,and positively correlated with the AD values of the right uncinate fasciculus.The CARS scores were positively correlated with the AD values of the right uncinate fasciculus(P<0.05).The FA values of the right inferior longitudinal fasciculus were negatively correlated with language problems and sensory abnormalities in children with ASD,while the RD values were positively correlated with social impairments and sensory abnormalities.The FA values of the right uncinate fasciculus were negatively correlated with language problems,social impairments,and sensory abnormalities,while the RD values were positively correlated with these clinical symptoms.The AD values of the right uncinate fasciculus were positively correlated with social impairments and health issues.In addition,the FA values of bilateral infero-frontal-occipital fasciculus were negatively correlated with sensory abnormalities,and the RD values of the right infero-frontal-occipital fasciculus were positively correlated with social impairments and sensory abnormalities.The RD values of the right superior longitudinal fasciculus were positively correlated with sensory abnormalities.The AD values of the left anterior thalamic radiation were positively correlated with sensory abnormalities(P<0.05).Conclusions:Acupuncture may improve clinical symptoms in children with ASD,particularly in areas such as speech,social interaction,perception,and health problems,possibly by promoting the integrity of brain white matter fiber bundles.This further indicates the important value of DTI in evaluating the therapeutic effect of acupuncture.
