Objective　To analyze the language development profile of children with autism spectrum disorder (ASD). Methods　A total of 194 children who were firstly diagnosed with ASD at Developmental and Behavioral Pediatrics, the First Hospital of Jilin University from January 2018 to January 2019 were recruited in this study. The autism behavioral checklist (ABC) and the childhood autism rating scale (CARS) were used to examine the symptom severity of ASD, and the Gesell development scale was used to assess the language development level. The correlation between the language area developmental quotient (DQ) points of the Gesell developmental scale and the total ABC and CARS scores of the ASD children and the relationship among the DQ points, gender, and age were analyzed. Results　Prevalence of language developmental delay in the 194 children with ASD was 94%. The language area DQ points of the Gesell was negatively correlated with ABC total score and CARS total score (P＜0.05). Children with ASD in different genders had no significant statistical difference in DQ points of the language area of Gesell (P＞0.05). With the increase of age, DQ values in the language area of the Gesell tended to gradually decrease, however，there was no statistically significant difference in DQ values among different age groups (P＞0.05).  Conclusion　Children with ASD are commonly accompanied with language development delay, and the severity of ASD is negatively correlated with the level of language development. Children with ASD should be paid attention to language training when  social interaction intervention is carried out.

Objective　To investigate the family disease burden of children with autism spectrum disorder (ASD) in China, and provide a scientific reference for decision makers to allocate public resources and organize public services for people with ASD. Methods　A self­developed questionnaire was used to investigate 1 538 families of children with ASD in 13 cities in northern, eastern, western, southern, and central China. The main content of the investigation was the economic  and psychological burden of the family. Results　The median cost of medical treatment and rehabilitation for children with ASD in China was 60 000 yuan/year, of which 60 000 yuan/year in the north, 80 000 yuan/year in the east, 60 000 yuan/year in the west, 50 000 yuan/year in the south, and 60 000 yuan/year in the central area. There were significant differences among different regions (P<0.05). Among the families, 61.15% resigned because of ASD childcare issues,  43.90% moved to another place for rehabilitation, and 67.04% had family conflicts due to children's illness. Conclusion　ASD has caused serious economic and psychological burdens to the family. To create a better social and family environment for the rehabilitation of ASD children, the assistance and medical insurance coverage should be further increased, and more professional rehabilitation training institutions should be constructed. At the same time, attention should be paid to the psychological burden of family members of children with ASD and reasonable interventions should be implemented for related risk factors.
