ABSTRACT
Objective To explore the behavioral characteristics of response to name in 16-30 months old infants with autism spectrum disorders (ASD),in order to provide a theoretical basis for the early identification and early diagnosis.Methods Two professionals,according to the scoring criteria and using video analysis methods,evaluated the response score (RS),reaction time (RT),duration time (DT) and the rate (RR) of response to their names among ASD infants (ASD group,61 cases),who were diagnosed at Child Developmental and Behavioral Center,the Third Affiliated Hospital of Sun Yat-Sen University from April to December 2017.Then they were compared with infants with developmental delays (DD group,32 cases) and neuro-typical (NT group,33 cases) infants.Finally,researchers predicted the diagnosis for ASD infants according to the behavioral indicators,which had significant differences compared with other groups.Results Compared with DD group [RS 2 (1) score,RT 1.32 (4.65) s,DT 2.69(1.84) s] and NT group [RS 2 (1) score,RT 1.37 (4.37) s,DT 2.90 (2.23) s],RS was significantly lower [1 (1)score],RT was significantly longer [5.87 (4.64) s],and DT was significantly shorter [0.77 (1.88) s] in ASD group,and the differences were statistically significant (H =-4.91,-5.94;5.36,5.41;-4.47,-5.78;all P ＜0.05);while the differences between DD group and NT group were not significant(all P ＞0.05).The RR was significantly lower in ASD group [0.25 (0.50)] and DD group [0.50 (0.25)],compared with NT group [0.75 (0.50)],and the differences were statistically significant (H =-6.39,-4.45,all P ＜ 0.01);while the differences between DDgroup and ASD group were not significant(P ＞0.05).When detecting ASD from ASD and NT infants,the area under the receiver operating characteristic curve (AUC) was 0.889 (P ＜0.01);when detecting ASD from ASD and DD infants,AUC was 0.924 (P ＜ 0.01);when detecting ASD from all infants,AUC was 0.868 (P ＜ 0.01),according to all indicators of response to name.Conclusions There are significant differences between ASD infants and DD and NT infants in response to name domain.Behavioral characteristics in the procedure of response to name can predict ASDwell.Response to name as an early social behavioral indicator,being tested at 2 years old,is still of importance for the early identification and early diagnosis of ASD.
ABSTRACT
Objective To evaluation the efficacy and safety of endovascular stenting for intracranial artery stenosis.Methods By the checking of DSA,39 patients with intracranial artery stenosis were divided into the anterior circulation group [26 cases,including 11 cases of transient ischemic attack(TIA),15 cases of cerebral infarction(CI)] and posterior circulation group(13 cases,including 3 cases of TIA,10 cases of CI).All the patients were treated with endovascular stents.The rates of the stenting success,improvement rate of stenosis post-stenting and incidence of complications were compared between the two groups.In 6～12 months follow-up,DSA reexamination was performed,and the scores of mRS and BI in patients with CI between pre and post-stenting were compared.Results The rate of stenting success in anterior circulation group was 92.3%,and 100% in posterior circulation group.The improvement rates of stenosis compared pre-stenting in the two groups were all above 70%.The incidence of complications was 19.2% in anterior circulation group and 7.7% in posterior circulation group.There was no statistical difference between the two groups.There were 10 cases in anterior circulation group and 5 cases in posterior circulation group received DSA reexamination,and 50% restenosis was found in the 2 cases(1 case in each group).In the period of the follow-up,the score of mRS and BI at the 6 months and 12 months post-stenting of patients with CI were significant improved than pre-stenting(all P
