Methods Genomic DNAs of fifty subjects including 25 autistic children and 25 controls were extracted from blood samples. PCR amplification using Oligonucleotide primers flanking 5-HTTLPR was performed. Results ① Three kinds of alleles including the S (short) allele, the L (long) allele and the VL allele were found , and the 5-HTTLPR genotypes shown were S/S, L/L, S/L and L/VL. ② Allele frequencies did not differ significantly in patient groups in comparison with the control sample. No significant difference was identified between the observed 5-HTTLPR genotype distribution of the patient groups and control group. ③ The distribution of homozygous and heterozygous subjects between the two groups differed significantly. ④ The genotypes of the 5-HTTLPR polymorphism correlated significantly with the Body Movement Factor. ⑤ The allele frequency of healthy Han Chinese population and that of healthy Japanese population were similar. The frequency of S allele in not only autistic subjects but also healthy children in this study was considerably more than that in Caucasians and the frequency of L allele in our subjects decreased correspondingly. Conclusion ① A significant difference in the allele frequency between the Han Chinese and Caucasian populations was found. ② The genotypes of the 5-HTTLPR polymorphism correlated significantly with the Body Movement Factor of the patients. ③ The homozygote and the L allele were positively relevant to CA and they might be the risk factors of CA. The heterozygote and the S allele were negatively relevant to CA and they might be the protective factors of CA.展开更多

We analyzed the data of the Childhood Autism Rating Scale (CARS) of 44 students at the high school course of a special needs education school who participated in agricultural vocational training. The data were divided into two groups according to the scores of “General Impressions”, one of 15 question items of the CARS: one was the group whose score was 1 (usual), and the other was the group whose scores were 1.5 to 4 (unusual). The results of the Mann-Whitney U test showed significant differences between two groups in eight items including “Relating to People” (p Relating to People” with six other items. As a result, “Relating to People” was considered to be the most effective item to know the participant’s autistic characteristics at a very early stage of training. Eventually, adding two items, “Body Use” and “Imitation” which are necessary to master agricultural tasks, to “Relating to People”, we proposed three indicators.展开更多

Compared with the ADSL group, the early-onset CDD group had a tendency to have a higher rate of a psychosocial event before speech loss (SL) (early-onset CDD, 75.0% vs ADSL, 37.0%, p = 0.057;effect size (phi) = 0.211, p < 0.05);a significantly higher rate of fearfulness during SL (62.5% vs 4.3%, p = 0.000;phi = 0.551, p < 0.05);and a tendency to have a higher rate of epilepsy (25.0% vs 3.3%, p = 0.050;phi = 0.271, p < 0.05), a tendency to have a lower rate of the Childhood Autism Rating Scale-Tokyo Version (CARS-TV) total score ≥ 30 (75.0% vs 95.7%, p = 0.072;phi = 0.236, p < 0.05), and a significantly lower rate of CARS-TV item 2 (imitation) score ≥ 2 (50.0% vs 82.6%, p = 0.049;phi = 0.221, p < 0.05) on the first visit. The two groups did not exhibit any significant difference in the other 19 variables. The findings of no significant difference in the great majority and a significant difference in the small minority of the 24 variables between the two groups support integrating CDD into regressive autism spectrum disorder and studying CDD as its prototypical form.展开更多
