Objective To explore the radical surgery for tetralogy of Fallot combined with right pulmonary artery stenosis.Methods Thirteen cases with tetralogy of Fallot combined with right pulmonary artery stenosis accepted radical surgery,among them 7 cases who-had a long right pulmonary artery stenosis accepted aortic transaction for radical surgery of tetralogy of Fallot;5 cases who had the entrance stenosis of the right pulmonary artery accepted right pulmonary artery patch expansion for radical surgery of tetralogy of Fallot;One case who had the distortion and stenosis after pulmonary shunt accepted the radical surgery for tetralogy of Fallot after seperation and expansion.Results There were no operation-related deaths,post-operative low cardic output and perfusion lung occurred for all the cases.Ten cases had grade 1 cardiac function and 3 cases had grade 2,respectively.Conclusion Right pulmonary artery stenosis increased the risks during the radical surgery for tetralogy of Fallot,but it is still the primary operation choice.

Objective: To understand the relationship between emotional behavior and literacy of primary school students, and to provide evidence for improving the literacy of primary school students. Methods: A total of 3 710 students in grade 2 to 3 from three schools in Xinjiang were selected by random cluster sampling method, and were investigated with the Literacy Scale for Primary School Students and the Strengths and Difficulties Scale. Results: The average literacy of the second and third grade students( 947.85 ±335.93，1 519.45±509.88) were lower than the Shanghai literacy norm(1 414, 2 135), and the differences were statistically significant ( t =-62.15, -49.84, P <0.01). The abnormal detection rates of emotional behavior were peer communication problems (12.40%), prosocial behavior (12.02%), hyperactivity (11.59%), conduct problems (10.49%) and emotional problems (5.88%). Emotional symptoms ( r =-0.19), conduct problems ( r =-0.29), hyperactivity attention deficit ( r =-0.27), peer communication problems( r =-0.24) were negatively correlated with literacy scores( P <0.01). Regression analysis showed that peer interaction problems ( β =-24.45), hyperactivity problems ( β =-42.04) and conduct problems ( β =-50.73) had negative predictive effects on literacy ( R 2=0.12)( P <0.01). Conclusion Peer interaction problems, hyperactivity problems and conduct problems are moderately related to the literacy of primary school students.In the process of teaching, teachers should combine the psychological characteristics of students, adopt the teaching strategy of combining centralized literacy with written literacy, pay attention to the cultivation of literacy ability.

Objective: To investigate the characteristics of visual motor integration in children with developmental dyslexia and ADHD, and to provide a reference for the diagnosis and treatment of these children. Methods: During July to November of 2020，students from grade 3 to grade 5 of 7 primary schools in Xinjiang were selected by using random cluster sampling method. A total of 56 dyslexia group (group DD), attention deficit hyperactivity disorder group (group ADHD), comorbidity group and normal control group were selected and compared the differences of their visual motor integration ability and related factors ability. Multiple linear regression analysis was used to explore the predictive effects of related factors on visual motor integration ability. Results: The scores of visual integration ability and visual perception in comorbidity group (95.05±14.01, 12.71±7.40) were lower than those in DD group (104.77±17.19，23.04±11.48), ADHD group (104.00±14.11，25.70±10.74) and normal control group (129.80±12.91, 44.05±16.56) ( F/Z =58.24,110.49, P <0.05). The visual working memory score of the comorbidity group ( 73.64 ±5.36) was lower than the normal control group (78.96±4.68) ( P <0.05)，and there was no significant difference between the DD group (74.48±7.06) and the ADHD group (75.98±7.36) ( P >0.05). The results of multiple regression showed that visual perception, age, IQ and visual working memory were associated with visual and motor integration ability of dyslexia children with ADHD ( R 2=0.32，0.17，0.11， 0.04 ， P <0.05). Conclusion Visual motor integration and visual perception among children with DD combined ADHD are more severely impaired than those with ADHD and DD alone. Visual perception, age, IQ and visual working memory could help predict the development of visual and motor integration ability in children with DD combined ADHD.

Abstract The possible mechanisms of developmental dyslexia mainly include the hypothesis of language framework and the hypothesis of non-verbal framework. The language framework assumes that people with developmental dyslexia may exhibit defects in phonetic awareness, rapid naming, phonetic memory, and orthographic processing. Studies of developmental dyslexia in Chinese have found that deficiencies in orthography may be an important cause of dyslexia, but there are diverse views and opinions regarding orthography processing. This article sorts out the research progress in behavioral and neuroimaging aspects of orthography studies, and provides references for further development of processing test materials and methods in the research of processing mechanism of developmental dyslexia orthography.

Objective: To characterize visual attention span in children with developmental dyslexia in Xinjiang and to explore the effects of action video game training on visual attention span,and to provide a reference for improving the visual attention span of children with dyslexia. Methods: Students from grade 3 to 5 in primary schools of Xinjiang were selected by using random clustering sampling method from July to November 2020,a total of 120 developmental dyslexia group (Group-DD), chronological age matched group (Group-CA) and reading level matched group (Group-RL) were selected and compared with visual attention spans, action video games were used to conduct intervention training for DD children, variance analysis was used to study the variation of visual attention span. Results: The accuracy and discrimination index of Group-DD (0.68±0.10, 1.21±0.87) were lower than those of Group-CA (0.77±0.99, 1.80±0.83) and Group-RL (0.71±0.11, 1.50±0.75) ( F =21.26, 15.19, P <0.05);there was no significant difference in reaction time among the three groups( P >0.05). There were statistically significant differences in the accuracy of visual attention span (0.63±0.12, 0.71±0.11,0.70±0.10), response time (760.51±185.83, 782.74±149.20, 857.27± 155.44 ), and discrimination (0.84±0.81, 1.51±0.19, 1.29±0.10) among children of different grades ( F =6.37，3.81，3.16， P < 0.05 ). After 12 hours of action video game training, the accuracy and discrimination of Group-DD intervention group (0.74±0.10, 1.53±0.88) were higher than those of Group DD control group (0.68±0.14, 1.06±0.97)( P <0.05), and there was no significant difference between Group DD intervention group and Group RL (0.76±0.12, 1.73±0.71) ( P >0.05), but there was statistical difference between Group DD intervention group and Group-CA (0.81±0.94, 2.17±0.79) ( P <0.05). Conclusion Children with dyslexia have deficits in visual attention span, with grade difference. Action video game intervention can improve visual attention span ability of developmental dyslexia children to some extent.

Objective:To analyze the influencing factors of attention deficit hyperactivity disorder (ADHD) in children and construct a Nomogram prediction model.Methods:A total of 5 409 children aged 7 to 16 from 5 schools in Xinjiang were investigated by using SNAP-Ⅳ assessment scale and influencing factors questionnaire.Least absolute shrinkage and selection operator (LASSO) regression and multivariate Logistic regression were used to analyze and investigate the influencing factors of ADHD in children, and then Nomogram prediction model was established. Results:(1)The detection rate of ADHD was 7.3%.(2) The LASSO- Logistic regression model showed that the history of febrile convulsions ( OR=5.97, 95% CI: 3.52-9.86), the history of epilepsy disease ( OR=11.86, 95% CI: 7.83-17.89), the history of head trauma disease ( OR=10.0, 95% CI: 7.27-13.71), mother′s delivery method ( OR=2.53, 95% CI: 1.99-3.23), mother′s education level ( OR=2.26, 95% CI: 1.45-3.67), mother′s smoking more than 1 year ( OR=12.65, 95% CI: 8.30-19.34), whether the family environment is quiet ( OR=1.27, 95% CI: 1.00-1.63), and the education method of beating and scolding ( OR=3.05, 95% CI: 2.13-4.31) was an indepen-dent risk factor for children with ADHD; (3)The Nomogram prediction model was built and verified by Bootstrap for 1 000 samples.The C-index was 0.81(95% CI: 0.78-0.83), suggesting that the Nomogram prediction model has good prediction ability, accuracy, and distinction.Decision curve analysis (DCA) of the clinical decision curve suggested that patients with Nomogram model with a predictive probability threshold greater than 0.2 had a higher clinical net benefit. Conclusions:The detection rate of ADHD was 7.3%, which was higher than the national average.The Nomogram prediction model drawn here can provide individualized ADHD risk predictions for children based on the history of hyperthermia, epilepsy, and head trauma, maternal mode of childbirth, maternal education level, maternal education level, maternal smoking for more than 1 year, quiet family environment, and scolding education methods.
