ObjectiveTo explore the characteristic and difference of the executive function of the premeditated group and attack group of male juvenile delinquents by the Stroop test.Methods 123 male juvenile delinquents and 128 normal controls were examined by a general information questionnaire,the Stroop test of the Chinese version and impulsive premeditated aggression scale (IPAS).SPSS17.0 statistical software used to analysis the survey results.Results ( 1 ) By Stroop test the premeditated group and impulsive group of juvenile delinquents was found that correct number of test 3( 109.97 ± 1.87),errors number of test 4(4.45 ±4.84),amend number of test 1 and test 4 ( 1.18 ± 1.50 ; 1.50 ± 1.59 ),and completion time of test 4 ( 143.74 ± 28.36) had statistically significant (P ＜ 0.05 ),the others had no significant difference between the two groups.(2) The premeditated group of juvenile delinquents and normal adolescents in Stroop test comparison was statistically significant in completion time of test 1,test 2 (56.49 ± 14.90 ;88.31 ± 20.02)(P ＜ 0.05 ).The impulse group of the juvenile delinquents and normal adolescents was statistically significant in the correct number of test 2 to test 4( 107.20 ± 3.39 ; 109.97± 1.87 ; 102.47 ± 5.62 ),errors number of test 2 ( 1.86 ± 2.27 ),amends number of test 3 ( 1.50 ± 1.59 ),and completion time of test 1 to test 4 (59.96 ± 11.08 ;92.03 ± 20.87 ;62.77 ± 12.31 ; 143.74 ± 28.36) (P ＜ 0.05 ).The others of two groups were no significant difference.ConclusionIt is found that juvenile delinquents exist defects of executive function,and perform functional defects in the attack group of juvenile delinquents is more obviously.

Objective:To explore the role of objective teaching guided by immersion education theory in the practice teaching of undergraduates majoring in psychiatry.Methods:Two classes of undergraduates majoring in psychiatry in Batch 2018 were randomly selected as the study group and the control group. A total of 35 students in the control group had traditional teaching, and 37 students in the study group had objective teaching guided by immersion education theory, both with half a semester of teaching. After the teaching, the theoretical knowledge examination scores and skills assessment scores, comprehensive ability (self-learning ability, communication ability, clinical thinking, innovation ability, and humanistic care ability), and teaching satisfaction of the two groups were compared. SPSS 26.0 was used for t-test, Chi-square test, and rank sum test. Results:After the teaching, the theoretical knowledge examination scores (basic medicine, clinical medicine, clinical psychology, and psychiatry), skill assessment scores (physical examination, and mental examination), self-learning ability, communication ability, clinical thinking, innovation ability, and humanistic care ability of the study group were all higher than those of the control group ( P<0.05). The teaching satisfaction degree of the study group was higher than that of the control group, and the difference was statistically significant ( P<0.05). Conclusion:Objective teaching guided by immersion education theory can improve the scores of professional theoretical knowledge scores and skills assessment scores of undergraduates majoring in psychiatry, and improve teaching satisfaction.

Objective To investigate the effect from circumferential distribution angle of forwards wedge vortex generators on aerodynamic drag reduction during flow around a cylinder, so as to provide theoretical evidences for low drag sprint garment design. Methods Forwards wedge vortex generators were reconstructed based on the NIKE’s AeroBalde. Given that the individual parts of an athlete body can be treated as multiple cylinders with varied dimensions and positions, 48 forwards wedge vortex generators were distributed as four columns on windward side of the cylinder, which were symmetrical with the YOZ plane. When the air flowed through the cylinder at the speed of 32 km/h, large eddy simulation was carried out on the computational domains which were properly meshed with polyhedral mesh to investigate the drag force, flow filed and pressure distributions. Results It was effective for drag reduction of the cylinder induced by airflow when two columns of forwards wedge vortex generators were circumferential distributed in the range of 55°-75°and the circumferential internal angle between two columns was in the range of 10° or 15°. The pressure distribution on leeward side of the cylinder was apparently changed after surface modification, which minimized the pressure drag dominant in aerodynamic drag. The drag reduction mechanism was that micro-vortices were generated downstream after flow through the forwards wedge vortex generators, which resulted in an early transition to critical flow with low drag force. Conclusions Effective aerodynamic drag reduction is achieved if forwards wedge vortex generators are properly distributed. The research findings can provide guidance for wind tunnel test and low drag sprint garment design.

Objective To explore the correlation between exon region polymorphism of PPP1R3A gene and schizophrenia in Uygur Chinese population. Methods PPP1R3A gene exon region DNA amplification was performed using multiple PCR targeted capture next-generation sequencing method in 528 patients with schizophrenia and 576 healthy controls of Uyghur descent, Illumina HiSeq X Ten was used for sequencing, the symptoms of schizophrenia were assessed by positive and negative symptoms scale (PANSS). Results The allelic and genotypic distributions in rs1800000 of PPP1R3A gene between patients with schizophrenia and healthy controls had significant difference (P＜0.05), rs1799999 in genotype frequency between the female case and control groups showed significant difference (P＜0.05). Furthermore, the allelic distributions of rs8192686 between male cases and controls had significant difference (P＜0.05). Conclusion PPP1R3A gene rs1800000 may be associated with the development of schizophrenia in Uygur Chinese population; rs1799999 may be a risk factor for susceptibility of female Uygur Chinese schizophrenia; The C allele at rs8192686 may be associated with male Uygur Chinese schizophrenia.
