Association between social ability deficiency and core symptoms, emotional and behavioral problems in children and adolescents with attention deficit hyperactivity disorder / 中华行为医学与脑科学杂志

Objective:To investigate the characteristic of social ability in children and adolescents with attention deficit hyperactivity disorder (ADHD) and its relationship with core symptoms, emotional and behavioral problems.Methods:Fifty-nine children with ADHD aged 6-13 for outpatient department from June 2019 to June 2021 were selected as the ADHD group, and 62 normal children matched in age and sex were recruited as the typical development group(TD group). The social responsiveness scale (SRS), SNAP-Ⅳ rating scale and strengths and difficulties questionnaire (SDQ) were used to evaluate the social ability, core symptoms and emotional and behavioral problems of the subjects.SPSS 26.0 was used for statistical analysis.Non parametric test was used to compare and analyze the differences in social ability, emotional and behavioral problems between the two groups.Spearman correlation analysis was used to analyze the relationship between social ability and core symptoms, emotional and behavioral problems of ADHD group.Generalized linear regression was used to analyze the impact of gender, age, IQ, core symptoms, emotional and behavioral problems of ADHD group on social ability.Results:In the ADHD group, the total score of SRS (65(42, 83)), social perception (10 (8, 13)), social cognition (13 (9, 19)), social communication (19 (11, 29)), and autism like behavior (9 (5, 14)) were significantly higher than those of TD group(38 (27.5, 59.5), 7 (4, 12.5), 8 (6, 15), 12 (6.5, 20), 4 (2, 11)) ( Z=-2.97, -2.75, -2.41, -3.01, -2.64, all P<0.05) .The total score of SDQ difficulty, influence factors, mood, hyperactivity, conduct and peer interaction were significantly higher than those of TD group ( Z=-5.80, -6.89, -2.82, -8.59, -2.52, -3.81, all P<0.05). The total score of SRS and the scores of each subscale in ADHD group were positively correlated with the total score of SNAP -Ⅳ and the scores of each subscale ( r=0.33-0.71, all P<0.05). The total score of SRS and the score of social communication scale were positively correlated with the total score of SDQ difficulty, influencing factors, emotion, hyperactivity, conduct and peer interaction subscale ( r=0.29-0.65, all P<0.05). Social perception was positively correlated with the total score of difficulty, hyperactivity and the scores of peer interaction subscale ( r=0.56, 0.32, 0.45, all P<0.05). The scores of social cognition and autism like behavior subscale were positively correlated with the total scores of difficulty, influencing factors, emotion and peer interaction subscale ( r=0.27-0.55, all P<0.05). The scores of social motivation subscale were positively correlated with the total scores of difficulty, emotion, hyperactivity, conduct and peer interaction subscale ( r=0.29-0.55, all P<0.05). The total score of SRS and the scores of each subscale were negatively correlated with the scores of prosocial behavior subscale ( r=-0.63--0.49, all P<0.05). The total score of SRS was positively affected by gender, age, opposites and disobedience, emotion, hyperactivity and peer interaction ( B=0.05-0.23, all P<0.05), and negatively affected by the prosocial behavior subscale ( B=-0.07, P<0.05). Conclusion:ADHD children often have obvious social ability defects, which are clearly related to core symptoms, emotional and behavioral problems.The risk factors are opposition and disobedience, emotions and peer relationships, and the protective factor is prosocial behaviors.

Effect of play-based communication and behavior intervention on improving internalizing and externalizing behaviors in children with autism spectrum disorder / 中华行为医学与脑科学杂志

Objective:To explore the effect of play-based communication and behavior intervention (PCBI) on internalizing and externalizing behaviors in children with autism spectrum disorder (ASD).Methods:From November 2018 to November 2021, 90 ASD children aged 8-30 months who registered in the Child Mental Health Research Center of the Affiliated Brain Hospital of Nanjing Medical University for PCBI ultra-early intervention training were selected and randomly assigned to the intervention group( n=60) and the waiting group( n=30) according to the ratio of 2∶1.Behavioral videos of free play between children and caregivers were collected before and after the 12-week intervention and the behavioral observation and analysis system (Observer XT) was used to code the parent-child interaction status and children's internalizing and externalizing behaviors.SPSS 23.0 statistical software were used and the data were analyzed by t-test, chi-square test, Pearson correlation analysis and multiple linear stepwise regression analysis. Results:After the intervention, the children in the intervention group had improved internalizing and externalizing behaviors (2.43±2.22, 1.88±1.91) compared with those before the intervention (4.82±3.37, 3.68±5.68), and the difference was statistically significant ( t=4.66, 2.60, both P<0.05). The children in the waiting group had no significant difference in internalizing and externalizing behaviors before (4.23±2.47, 4.00±2.18) and after intervention (4.37±2.57, 4.67±3.72) ( t=-0.23, -0.83, both P>0.05). After intervention, the children in the intervention group had fewer internalizing and externalizing behaviors than those in the waiting group, and the difference was statistically significant ( t=-3.70, -4.71, both P<0.05). The differences in internalizing behaviors (2.38±3.96, 1.80±5.37) and externalizing behaviors (1.80±5.37, -0.67±4.38) between the two groups before and after the intervention were statistically significant ( t=3.03, 2.18, both P<0.05). The results of multiple linear stepwise regression showed that the negative interaction of caregivers ( β=0.29, P<0.01) was a risk factor for internalizing behaviors.The negative interaction of children ( β=0.45, P<0.01) was a risk factor for externalizing behaviors, and the child's object status ( β=-0.30, P<0.01) and binary interaction ( β=-0.39, P<0.01) were protective factors for externalizing behaviors.In the intervention group, active child interaction, active caregiver interaction, and binary interaction increased after the intervention ( t=-6.77, -4.58, -7.72, all P<0.05), while the child's object status and the caregiver's negative interaction decreased ( t=3.37, 4.30, both P<0.05). Conclusion:The PCBI ultra-early intervention can effectively improve the internalizing and externalizing behaviors of ASD children.Improvements in internalizing behaviors may work by reducing negative caregiver interactions, and improvements in externalizing behaviors may work by increasing parent-child binary interactions.

Characteristics of exploratory behavior in high risk autism spectrum disorder infants / 中华实用儿科临床杂志

Objective:To compare the differences in exploratory behaviors between infants with high-risk autism spectrum disorder (HR-ASD) and normal development (TD) infants, and to explore the relationship between exploratory behaviors and the severity of ASD symptoms.Methods:A total of 31 infants aged 6-23 months with HR-ASD in the Pediatric Clinic, the Affiliated Brain Hospital of Nanjing Medical University from January 2019 to August 2020 were retrospectively recruited in the HR-ASD group, and 37 TD infants aged from 6 to 23 months in Nanjing were selected as the TD group.The development level of the 2 groups was evaluated by Gesell development scale, and the depth and breadth of exploratory behaviors were measured in free play.Autism Diagnostic Observation Schedule (ADOS) was used to evaluate the severity of ASD symptoms in HR-ASD group.Differences in exploratory behaviors between the 2 groups were analyzed by the independent sample t-test and Chi- square test. Pearson′ s correlation analysis was performed to explore the correlation between exploratory behaviors and symptom severity in HR-ASD group.Binary Logistic regression analysis was used to explore the discrimination efficiency of sexual behavior in the 2 groups. Results:Compared with TD group, the depth and breadth of exploratory behaviors in HR-ASD group were significantly lower (55.06±25.73 vs.132.78±44.69, 4.42±2.20 vs.8.78±3.28)( t=-8.95, -6.53, all P<0.01), and atypical exploratory behavior and avoidance withdrawal behavior were significantly worse [18 cases(58.06%) vs.6 cases(16.22%), 10 cases(32.26%) vs.3 cases(8.11%)]( χ2=15.30, 6.36, all P<0.05). Significant differences in the frequency and duration of object exploration, environmental exploration and social exploration were detected between HR-ASD group and TD group (3 vs. 0 vs. 0, 45 vs. 0 vs. 0)(all P<0.01). Pearson correlation analysis showed that, the frequency of object exploratory behavior was positively correlated with the dimension of ADOS in HR-AD group ( r=0.40, P<0.05); while the duration of object exploratory behavior, the complexity of object explo-ratory behavior and the depth of exploratory behavior were negatively correlated with CARS score ( r=-0.45, -0.47, -0.42, all P<0.05). The depth of exploratory behavior was negatively correlated with the stereotyped dimension of ADOS ( r=-0.40, P<0.05). Binary Logistic regression analysis showed that the depth of exploratory behavior had a discrimination effect ( P<0.01). Conclusions:The characteristics of exploratory behaviors in HR-ASD infants are abnormal, especially the distinguishing effect on the depth of exploratory behaviors, which can be used as a candidate behavioral index for early screening of ASD.

Characteristics of perspective-taking in children with attention deficit hyperactivity disorder and its correlation with executive function / 中华行为医学与脑科学杂志

Objective:To explore the differences between impaired perspective-taking and executive function in children with attention deficit hyperactivity disorder(ADHD).Methods:From January 2019 to December 2020, according to DSM-5 diagnostic criteria, thirty-two cases of ADHD children aged 6 to 16(ADHD group) and twenty-six cases of typical development children and adolescents matched with age and intelligence (TD Group) were included. The response time and accuracy rate in dilemma stage and probe stage to self-oriented, maternal perspective-taking and other perspective-taking were measured using perspective-shifting task, and the executive function was evaluated by the behavior rating inventory of executive function (BRIEF). Repeated measurement analysis of variance was used to compare the difference of response time and accuracy rate between the two groups. Pearson correlation analysis was used to explore the correlation between the perspective-taking behavior characteristics and the BRIEF total score and subscale scores of ADHD group.Results:The total score and subscale scores of BRIEF scale in ADHD group were significantly higher than those in TD group (all P<0.01). The interaction between group and task type was significant during the task dilemma stage of perspective-shifting task ( F(2, 106)=4.365, P<0.05). Simple effect analysis showed that in other-perspective-taking task, the response time of ADHD group ((2 305.48±464.27)ms) was significantly longer than that of TD group ((1 971.13±462.95)ms) and the difference was statistically significant ( t=2.870, P<0.01). Pearson correlation analysis showed that the response time of ADHD group to other perspective-taking in dilemma stage was positively correlated with working memory, organization and inhibition index in EF ( r=0.401, 0.432, 0.342, all P<0.01). Conclusion:The ability of the perspective taking is closely related to impaired executive function, which seem to share a common neuropsychological basis.

Analysis of 90 hospitalized children with refractory Tourette′s syndrome / 中华实用儿科临床杂志

Objective:To analyze the diagnosis and treatment process, treatment methods and clinical efficacy of children with refractory Tourette′s syndrome (TS), thus providing a basis for comprehensive prevention and treatment of refractory TS.Methods:A total of 90 children with refractory TS treated in the Child Mental Health Research Center of Nanjing Brain Hospital Affiliated to Nanjing Medical University from May 2012 to July 2019 were recruited.Their baseline characteristics, diagnosis of comorbidities before and after hospitalization, combined non-drug therapy during hospitalization, the drug types used before and after admission, the dosages of main anti-tic drugs used before admission and at discharge, and the treatment outcomes of comorbidities after admission were retrospectively analyzed.The Yale global tic severity scales (YGTSS) scores and the reduction rate were used to assess the severity of tic disorder and therapeutic effect, and the clinical global impression-efficacy index (CGI-EI) scores were graded for assessing the final therapeutic efficacy.Results:Among the 90 children with refractory TS, 82 children were males and 8 children were females.There was a significant difference in the YGTSS scores at admission and discharge (25.04±12.77 vs.67.64±12.46) ( t=27.55, P<0.05). The proportion of all recruited children diagnosed with comorbidities at discharge was significantly higher than that of admission (85.56% vs.47.78%, χ2=28.90, P<0.05). Combined non-drug therapies after admission mainly included psycho-education and supportive therapy (90 cases), comprehensive behavioral intervention for tics (47 cases) and relaxation therapy (19 cases). The distribution of drugs used before and after admission was the same, and there was no significant difference in the dosages of the five major anti-tic drugs before admission and at discharge (all P>0.05). There were no significant differences in YGTSS scores and reduction rate, and CGI-EI scores of children with or without comorbidities before and after admission (all P>0.05), suggesting the similar therapeutic outcomes. Conclusions:There is no difference in efficacy between outpatient treatment and anti-tic medication of children with refractory TS, and a comprehensive hospitalized intervention can significantly improve their clinical symptoms.Diagnosis and treatment of comorbidities and combined non-drug treatments like comprehensive psychological and behavioral interventions are the key events to improve the prognosis of children with refractory TS.

Effect of play-based communication and behavior intervention on toddlers with autism spectrum disorder / 中华实用儿科临床杂志

Objective To compare and analyze the short-term effect of play-based communication and behavior intervention (PCBI) and applied behavioral analysis (ABA) on the treatment of toddlers with autism spectrum disorder (ASD).Methods Seventy-four ASD toddlers aged from 19 to 30 months were recruited in Nanjing Brain Hospital Affiliated to Nanjing Medical University from November 2017 to May 2018.The toddlers who participated in this study were randomly assigned into PCBI group and ABA group,then they were intervened weekly by PCBI or ABA for a total of 12 weeks.Portage Early Development Checklist and autism treatment evaluation checklist (ATEC) were used to estimate the toddlers' developmental level and the treatment efficacy respectively.The t-test was used to reveal whether there was significant difference between the 2 groups before and after intervention.Results (1) Compared with the ABA group,there was a significant increase in cognitive scores (△PCBI =9.03 scores,△ABA =4.27 scores,t =3.997) and a significant decrease in social behavior scores (△PCBI =8.87 scores,△ABA =16.91 scores,t =-4.022) of the Portage Early Development Checklist after 12 weeks of intervention in the PCBI group,and there were statistically significant differences(all P ＜ 0.001);while the total score and the scores of language,movement,and self-care subscale of Portage Early Development Checklist were also increased after PCBI intervention but without significant differences (all P ＞ 0.05).(2)Compared with the ABA group,after 12 weeks of PC BI intervention,the scores of social contact,perception,behavior of ATEC were decreased,but the difference was not significant (P ＞ 0.05);the total score of ATEC scale(△PCBI total =14.89 scores,△ABA total =22.22 scores,t =2.209)and the scores of language subscale(△PCBI language =2.89 scores,△ ABA language =6.43 scores,t =2.515) were decreased significantly,and there were statistically significant differences (all P ＜ 0.05).Conclusions After 12 weeks of the very early intervention of PCBI,the ASD toddlers all improved in clinical symptoms and developmental level.Compared with ABA intervention,PCBI very early intervention with parental guidance was comparable in short term efficacy,and PCBI was not taking up as much medical rehabilitation resources as ABA.

Related factors of aggressive behavior among school aged children in Nanjing / 中国心理卫生杂志

Objective:To study the distribution and related factors of aggressive behavior among school aged children in Nanjing.Methods:Totally 4678 primary school students in Nanjing were sampled by cluster random sampling in this study.The General questionnaire and Achenbach's child Behavior Checklist were used to investi gate the general situation and aggressive behavior.Results:The rate of aggressive behavior of school-age children in Nanjing was 3.6 ％ (167/4678).Multivariate logistic regression analysis indicated that democratic parenting style [other parenting styles (OR =1.94,95％ CI =1.10-3.42),mixed parenting style(OR =1.96,95％ CI =1.35-2.85)],and genetic screening before birth (OR =0.71,95％ CI =0.52-0.99) were protective factors for children's aggressive behavior.The factor figures of aggressive behavior were positively correlated with that of oth er behavior problems in Pearson correlation analysis (r =0.52-0.80,Ps ＜0.01).Conclusion:About 3.6％ of the school aged children in Nanjing have aggressive behavior.It is more likely to have aggressive behaviors for children who is in other parenting styles except the democratic style and never have the genetic screening before birth.And children who with aggressive behavior may co-occur with other behavior problems.

Efficacy observation of GDP regimen for treatment of relapsed and refractory non-Hodgkin lymphoma / 白血病·淋巴瘤

Objective To analyze the efficacy of GDP regimen for treatment of relapsed and refractory non-Hodgkin lymphoma (NHL). Methods The clinical data of 40 patients with relapsed and refractory NHL in the Third Hospital of Peking University from January 2009 to June 2014 were retrospectively analyzed. All the patients underwent GDP regimen (gemcitabine, dexamethasone, cisplatin). The clinical features, laboratory data and survival status were analyzed. Results The overall response rate (ORR) of 40 patients was 67.5 ％ (27/40) with 27.5 ％ (11/40) complete remission (CR) rate and 40.0 ％(16/40) partial remission rate. The 3-year overall survival (OS) rate was 86.5 ％ and the OS rate of 5-year was 28.8 ％. The ORR and 3-year OS rate in B-cell lymphoma and T-cell lymphoma were 69.6 ％ (16/23) vs. 52.9 ％ (9/17) (P=0.283), 90.9％vs. 80.7％(P=0.480). The CR rate in patients with gastrointestinal tract involvement was better than that in patients without gastrointestinal tract involvement (P= 0.049). Meanwhile, the patients with gastrointestinal tract involvement were superior in 3-year OS rate (89.3％vs. 76.2％, but the difference was not statistically significant (P = 0.237). The major side effect was hematological adverse reactions. The incidence of grade Ⅲ/Ⅳ neutropenia was 47.5 ％, the rate of Ⅲ/Ⅳthrombocytopenia was 40.0％and the rate ofⅢ/Ⅳanemia was 17.5％. Non-hematological adverse reactions included mild nausea and vomiting.

Objective To explore the developmental characteristics of white matter volume in autism spectrum disorder (ASD) children longitudinal.Methods From May 2011 to September 2014,37 ASD children (ASD group)and 27 developmental delays (DD) children (control group) were treated at the Child Mental Health Research Center,Nanjing Brian Hospital Affiliated of Nanjing Medical University,and the children whose age,gender and developmental quotient matched with the ASD children were scanned by structure magnetic resonance imaging (sMRI) at the age of 2-3 years old and 4-5 years old respectively.Region of interest (ROI) technology was adopted to investigate the change of the cerebrum white and the sub-lobes structure white matter volume with time.Then the correlation between clinical symptoms and brain white matter volume changes was analyzed.Results Among the 2-3 years old,compared with the control group,the white matter volume of the total brain[(383 521.84 ±6 427.57) mm3 vs.(364 014.06 ±6 856.97) mm3],the left cerebral hemisphere [(191 609.35 ± 3 206.60) mm3 vs.(181 695.89 ± 3 389.54)mm3],temporal lobe [(41 860.49 ±816.38) mm3 vs.(39 444.18 ± 834.85) mm3] and the right temporal lobe [(21 312.79 ± 414.07) mm3 vs.(20 084.22 ± 412.13) mm3] were significantly larger in the ASD group,and the differences were statistically significant (all P ＜ 0.05).With the analysis of covariance with age or the total brain volume as the covariate,the differences disappeared(all P ＞ 0.05).Among the 4-5 years old,compared with the control group,the white matter volumes of the total brain[(417 651.42 ± 6 443.86) mm3 vs.(394 317.27 ± 6 404.86)mm3],left cerebral hemisphere [(208 714.16 ±3 214.61) mm3 vs.(197 192.82 ±3 262.02) mm3],right cerebral hemisphere [(208937.26±3242.09) mm3 vs.(7 124.45 ±3 193.13) mm3],frontal lobe [(107 107.46±1 681.99) mm3 vs.(100 326.19 ± 1 883.24) mm3],left frontal lobe [(54 569.63 ± 846.85) mm3 vs.(51 177.25 ±979.09) mm3],right frontal lobe [(52 537.83 ± 841.99) mm3 vs.(49 148.94 ±928.31) mm3],temporal lobe [(45 189.75 ± 833.29) mm3 vs.(42 487.73 ± 786.27) mm3],left temporal lobe [(22 204.21 ±411.77) mm3 vs.(20 922.90 ± 418.46) mm3],and right temporal lobe [(22 985.54 ± 426.93) mm3 vs.(21 564.83 ± 378.78) mm3]were significantly larger in the ASD group,and the differences were statistically significant (all P ＜ 0.05).With the analysis of covariance with age as the covariate,the differences still existed (all P ＜ 0.05).With the analysis of covariance with the total brain volume as the covariate,the differences disappeared (all P ＞ 0.05).For longitudinal analysis,there was a significant difference in the white matter volume between the whole brain,left cerebral hemisphere,right cerebral hemisphere,frontal lobe,left frontal lobe,fight frontal lobe,temporal lobe,left temporal lobe,right temporal lobe and the differences were statistically significant (F =5.521,5.533,5.459,5.830,5.800,5.723,4.857,4.418,5.159,all P ＜0.05).There was a positive correlation between the changes of the volume of whole brain,the white matter volume in the whole brain,bilateral cerebral hemisphere,frontal lobe,parietal lobe,right parietal lobe and Childhood Autism Rating Scale (r =0.367,0.343,0.321,0.349,0.296,0.308,0.351,all P ＜ 0.05).Conclusions Among the 2-3 years old,the white matter volume of the brain regions have been increased significantly in ASD.Among the 4-5 years old,the increase of the white matter volume of the brain regions implicated more widely which mainly concentrated in the frontal and temporal lobe in ASD.The severity of the clinical symptoms of ASD may be associated with the white matter volume of the total brain,bilateral cerebral hemisphere,frontal lobe,parietal lobe and right parietal lobe.

Clinical features and prognosis for anaplastic large cell lymphoma / 中南大学学报(医学版)

To determine clinical and pathologic profiles for anaplastic large cell lymphoma (ALCL).
 Methods: The clinical data of 22 patients with ALCL were analyzed retrospectively. Therapentie effect of different treatment strategies on ALCL was evaluated.
 Results: The median age for these patients was 32(9-70) years old and the patients with positive ALK accounted for 68.2% (15/22). All patients underwent chemotherapy, including regiments of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone), CHOPE (CHOP plus etoposide) or BEACOP (CHOP plus etoposide and bleomycin). Fourteen (63.6%) patients achieved initial complete remission (CR) and the CR rate for patients with ALK+ was significantly higher than that of patients with ALK- (P0.05). After a median follow-up of 41 (2-150) months, 12 patients were overall survival, the median progression free time was 22.5 (2-150) months, and the age, gender, stage, IPI index, ALK expression level, beta 2-MG level, LDH level, and B symptoms had no significant effect on the rate of overall survival (P>0.05).
 Conclusion: ALK-positive occurs mainly in ALCL patients. The chemotherapy is still the main treatment, and CHOPE regimen is a better initial treatment scheme because the most patients show good prognosis.

Co-stimulating molecule B7-H3 and tumors / 国际肿瘤学杂志

B7-H3,a newly discovered co-stimulatory regulatory protein member of the B7 family.Its mRNA is ubiquitously expressed in a wide spectrum of tissues.As a co-stimulatory or co-inhibitory signal molecule which can regulate immune response,B7-H3 plays an important role in the immune system.Besides,B7-H3 can be also involved in cancer progression via non-immunological.Recently,the aberrant expression of B7-H3 has been described in various malignancies,and significantly correlated with poor prognosis and cancer progression.Therefore,B7-H3 is considered as an early diagnostic and prognostic marker and therapeutic target for tumors,but the specific molecular mechanisms of B7-H3 regulation are poorly understood.The immune and gene therapy of tumor by target B7-H3 has made some progress.

An analysis of protective effect for mucositits by amifostine on total body irradiation during hematopoietic stem cell transplantation / 中华放射医学与防护杂志

Objective To evaluate the efficiency of amifostine in protecting against oral and gastrointestinal mucositis in hematologic malignancies patients with high-dose total body irradiation following the hematopoietic stem cell transplantation,and assess the hematologic recovery as well as the potential side effect of amifostine.Methods Thirty-two hematologic malignancies patients underwent hematopoietic stem cell transplantation in our institution from 2012 to 2016 were retrospectively analyzed.All of them were treated with total body irradiation (700-1 200 cGy) and high-dose chemotherapy,in which 14 patients received 400 mg amifostine before radiotherapy.Prior institutional experience in 18 patients treated without amifostine was used as a historical comparison (no-amifostine group).Results Severe oral mucositis occurred in 14.3％ of patients in the amifostine group while 77.2％ in the no-amifostine group (x2 =10.62,P ＜0.05).Total parenteral nutrition was used in 21.4％ of amifostine group and 38.8％ in noamifostine group (P ＞ 0.05).The rates of grade 2 and 3 gastrointestinal mucositis were 35.7％ and 61.5％ in amifostine group,while in no-amifostine group the rates were 33.3％ and 66.7％,respectively (P ＞ 0.05).No significant difference was found in engraftnent times of granulocyte and platelet.No amifostine related side effects were observed.Conclusions The combination of amifostine and total body irradiation conditioning therapy during hematologic stem cell transplantation might reduce the severity of oral mucositis.The utilize of amifostine has no obvious effect on hematopoietic recovery and can be well tolerated.

Structural change of the corpus callosum fibers in toddlers with autism spectrum disorder: two-year follow-up / 中华儿科杂志

Objective@#To conduct a follow-up investigation of structural changes of the corpus callosum fibers of toddlers (2 to 5 years of age) with autism spectrum disorder(ASD) and to explore the associations with clinical symptoms.@*Method@#In this prospective randomized controlled study, ASD children who were diagnosed in the Child Mental Health Research Center, Nanjing Brain Hospital Affiliated to Nanjing Medical University from May 2011 to November 2012 were included in the ASD group, and developmentally delayed children were included in the control group (DD group). Diffusion tensor imaging (DTI) data from the two groups were obtained at two age levels: 2-3 years of age, and 4-5 years of age. Region of interest analysis was applied to assess characteristic values of total area and sub-regions of corpus callosum: the fraction anisotropy (FA), the mean diffusivity (MD), the radial diffusivity (RD) and the axial diffusivity (AD). All children were assessed using the Autism Diagnostic Interview-Revised (ADI-R) and Autism Treatment Evaluation Checklist (ATEC). The characteristic values of total area and sub-regions of corpus callosum of ASD group at two age levels were analyzed by paired sample t test; the characteristic values of total area and sub-regions of corpus callosum of ASD group and DD group were analyzed by independent-sample t test; the correlations between FA values of the total area and sub-regions of corpus callosum and ADI-R or ATEC scores were analyzed by Pearson correlation analysis.@*Result@#Forty cases meeting inclusion criteria were enrolled in ASD group, and 31 eligible cases were enrolled in the control group. Four children in the ASD group were lost to follow-up, and 5 children in the control group were lost to follow-up. Longitudinal comparison between the two age subgroups of ASD patients showed that the FA values of the total corpus callosum increased (0.499 55±0.027 59 vs. 0.505 83±0.086 64, t=4.88, P<0.05), but MD values, RD values and AD values of the total corpus callosum area decreased (0.000 89±0.000 03 vs. 0.000 81±0.000 14, 0.000 61±0.000 04 vs. 0.000 55±0.000 09, 0.001 43±0.000 03 vs. 0.001 38±0.000 03, t=9.31, 7.90, 8.66, P<0.05 for all comparisons). In the area of corpus callosum genu, FA and AD values increased (t=5.59, 8.48, P<0.05 for both comparisons), but MD and RD values decreased (t=12.67, 11.28, P<0.05 for both comparisns). In the area of corpus callosum body, FA and RD values increased(t=5.46, 8.48, P<0.05 for both comparisons), but MD and AD values decreased (t=8.08, 6.22, P<0.05 for both comparisons). In the area of corpus callosum splenium, MD, RD and AD values decreased (t=6.81, 4.44, 5.51, P < 0.05 for all comparisons). Among the participants 2 to 3 years of age, there were no significantly differences in FA values of total area and sub-regions of corpus callosum between ASD group and the DD group (P > 0.05 for all comparisons); as compared with the DD group, ASD group had higher AD values of total area and splenium of corpus callosum (0.001 43±0.000 03 vs. 0.001 40±0.000 04, 0.001 34±0.000 03 vs. 0.001 32±0.000 04, t=1.56, 1.14, P < 0.05 for both comparisons); ASD group had lower AD values but higher RD and MD values of corpus callosum genu (t=0.07, 0.55, 0.07, P < 0.05 for all comparisons); ASD group had lower RD values of corpus callosum body (t=0.07, P < 0.05). Among the participants 4 to 5 years of age, as compared with the DD group, ASD group had higher FA value of total corpus callosum area(0.505 83±0.086 64 vs. 0.483 77±0.099 30, t=8.56, P < 0.05), lower RD value of total corpus callosum(0.000 55±0.000 09 vs. 0.000 56±0.000 12, t=14.44, P < 0.05), lower RD values of corpus callosum body (t=2.20, P < 0.05), higher FA values (t=3.35, P < 0.05) but lower AD values of corpus callosum splenium (t=2.20, P < 0.05). A correlation analysis between FA values of total area and sub-regions of corpus callosum and clinical variables showed that the FA values of total area and splenium of corpus callosum in ASD group at 2 to 3 years of age were negatively correlated with the scores of language skills in ATEC (r=-0.35,-0.36, P < 0.05 for both comparisons). And after two years, FA values of total corpus callosum were positively correlated with the scores of social communication in ATEC (r=0.34, P < 0.05). There was no significant correlation between FA values of sub-regions of corpus callosum and the scores of ATEC (P > 0.05 for all comparisons). There was no significant correlation between FA values of total area and sub-regions of corpus callosum and the scores of ADI-R (P > 0.05 for all comparisons).@*Conclusion@#The fiber structure of corpus callosum was still in the process of maturing during the age of 2 to 5 years; however, compared with DD group, ASD group had more extensive structural abnormalities of the corpus callosum fibers as age increased, and the structural abnormalities had correlation with the core symptoms of ASD.
