Objective To detect the genetic amplification and protein expression characteristics of aurora-A in ovarian cancer and to interpret the role of aurora-A gene in course of onset,progression and regression phases of ovarian cancer.Methods The amplification of aurora-A gene was detected by quantitative PCR in 6 normal ovarian tissues and 8 ovarian cancer samples,and its protein expression was examined by immunohistochemistry in 6 normal ovarian tissues and 40 ovarian cancer samples,furthermore,the relationships between over-expression of aurora-A protein in ovarian cancer tissue and its pathologic classification,tissue differentiation,clinical phase,tumor proliferation trait and prognosis were analyzed.Results Quantitive PCR showed that aurora-A mRNA was significantly higher in 8 ovarian cancer samples than that in normal ovarian tissues(P0.05).Conclusion There are abnormal amplification and protein over-expression of aurora-A in ovarian cancer tissue,aurora-A probably play an important role in the onset and progression of ovarian cancer,and the novel biological treatment concerning aurora-A gene and its protein is probably a useful route for curing tumor.

Objective To investigate the clinical and intellectual characteristics of children with cerebral palsy of ataxia type.Methods Twenty-one children with cerebral palsy of ataxia type were evaluated by the illness history,clinical physical examination,brain MRI scan and intellectual assessment.Results Delayed motor milestones and dysfunction of balance were found in these children,and 80.9% of brain MRI scan was abnormal as cerebellar damage,and delayed intellectual ability found in these children was ameliorated as improvement of motor function.Conclusion Cerebral palsy of ataxia type is mainly caused by cerebellar damage manifests as delayed motor function,dysfunction of balance and mental retardation.

Objective To investigate the efficacy of initial polytherapy in the patients with newly diagnosed infantile spasm by evaluating the ambulatory electronecephalogram (EEG) profiles and serum neuron specific enolase ( NSE ) level.Methods Data from 108 cases of newly diagnosed infantile spasm from Sep.2007 to Nov.2010 in the Department of Pediatrics,the First Hospital of Jilin University,were respectively analyzed for the EEG profiles and serum NSE level.The patients were treated with multiple drugs.Results ( 1 )After treatment,EEG showed normal shape in 56 cases ( 62.2％ ),sporadic sharp and slow waves without hypsarrhythmia in 32 cases( 35.6％ ),and hypsarrhythmia in 2 cases (2.2％).The overall effective rate was 97.8％.(2) Serum NSE in 35 seizure-free cases were examined at the time points of hospital admission,48 hours and one month after seizure cessation,respectively.NSE level was significantly decreased at 48 hours after seizure control than that at hospital admission ( t =6.54,P ＜ 0.05 ) ; NSE at one month after seizure free was further decreased compared with that at admission point ( t =9.29,P ＜ 0.05 ).Conclusion Polytherapy for infantile spasms can ameliorate the abnormal EEGs.NSE level is decreased after seizure cessation.Intelligence is improved 6 months after seizure free and polytherapy may improve the prognosis of the children with infantile spasms.

Objective:To analyze the autistic severity and developmental level of children with autism spectrum disorder (ASD) of different gender and age.Methods:From March 2018 to February 2019, a total of 286 ASD children aged 18-96 months were enrolled.Severity of ASD was evaluated by the autism behavior checklist (ABC) and the childhood autism rating scale (CARS), while the Griffiths mental development scales-Chinese (GDS-C) was used to evaluate the children's mental development.According to gender and age, ASD severity and developmental levels of different subgroups were analyzed.SPSS 23.0 statistical software was used to analyze the data.According to the non-normal distrbution of variables, Mann-Whitney U test was used for comparison between the two groups, and Kruskal-Wallis H test was used for comparison between multiple groups and Spearman correlation analysis was used to analyze the correlation between two variables. Results:No gender difference was found in the total scores of ABC (52(40, 62), 57(36, 67), Z=0.661, P=0.509) and CARS (31(28, 35), 33(27, 36), Z=0.672, P=0.502) between the ASD boys and ASD girls.No gender difference was found in the total scores of ABC (43(33, 53), 52(34, 58), Z=0.717, P=0.473) and CARS (29(26, 32), 27(26, 30), Z=0.212, P=0.832) between the ASD boys and ASD girls when the general quotient of the GDS-C were all greater than or equal to 70 points.Also, no gender difference was found in the total ABC (55(44, 67), 59(40, 67), Z=0.067, P=0.947) and CARS (32(30, 35), 34(30, 36), Z=0.657, P=0.511) between the ASD boys and ASD girls when the general quotient of the GDS-C were all less than 70 points.The eye-hand coordination (64(52, 77), 60(43, 72), Z=2.138, P=0.033), performance (68(51, 86), 59(43, 68), Z=3.270, P=0.001), and practical reasoning (68(55, 91), 51(33, 58), Z=2.686, P=0.007) quotients of the ASD boys were significantly higher than those of the ASD girls.Compared with boys, a markedly higher proportion of developmental delay (35(80%), 124(51%), χ 2=12.083, P=0.001) was recorded for girls in relation to the performance subscale.There were significant differences in the total scores of ABC and CARS, the locomotor and eye-hand coordination quotients in GDS-C among ASD children of different ages(all P<0.05). The older the first diagnosis age, the lower the scores.The age of initial diagnosis was negatively correlated with the total scores of ABC ( r=-0.259), CARS ( r=-0.268), general quotient of GDS-C ( r=-0.127), locomotor ( r=-0.275), eye-hand coordination ( r=-0.213), performance ( r=-0.160) and practical reasoning ( r=-0.307) (all P<0.05), while positively correlated with hearing and language development quotient ( r=0.143) ( P<0.05). Conclusion:No significant gender difference was found on the severity of ASD in children aged 18 to 96 months, but the developmental level of some areas in boys was better than that of girls with ASD.ASD severity and developmental level vary depending on the age at which their ASD was diagnosed.The age of initial diagnosis is related to the severity and developmental level of ASD.

Developmental coordination disorder (DCD) is a kind of movement disorder with lifelong adverse effects.According to motor learning and motor control theories, improving movement should be combined with individual, task and environment of children.Interventions for DCD children should not only be limited to the hospital, a more reasonable model should include the hospital, school and home three scenarios of combined treatment.This article expounds the importance and specific content of this intervention model, so as to provide reference for the healthy development of children with DCD.

Objective To investigate the effect of Early Intervention Denver Model ( Early Start Denver Model,ESDM) on children with autism spectrum disorder( ASD). Methods From May 2017 to April 2018,forty four children aged 2-5 years with ASD were enrolled in the study and were randomly divided into the experimental group(n=20) and the control group (n=20). The experimental group received ESDM rehabilitation intervention and the control group received conventional rehabilitation intervention. Before and 6 months after intervention,all children were assessed by the Psycho-educational Profile-3rd Edition ( PEP-3). Results After 6 months of intervention,the developmental age of cognition (30 (26,34),33(30,44);Z=-3. 728,P<0. 001),imitation (33(29,40),38( 32,43); Z=-2. 010,P=0. 044),expression language (29(23,39),41( 33,50); Z=-3. 923, P<0. 01), receptive language ( 25 ( 20,32),34 ( 28,38); Z=-3. 727,P<0. 01) and fine motor (29(23,41),39(33,47) ;Z=-2. 704,P=0. 007) of the control group were significantly higher than those before intervention. In the experimental group,the developmental age of cognition (25 ( 21,32),37 ( 32,40); Z=-3. 922, P<0. 01),imitation ( 22 ( 17,35),39 ( 38,42); Z= -3. 826,P<0. 01),expression language (30(24,35),47( 37,53); Z=-3. 824,P<0. 01),receptive lan-guage (22(15,32),37(30,43); Z=-3. 924,P<0. 01),fine motor (25(22,33),43(30,52); Z=-3. 924, P<0. 01) and gross motor ( 24(17,38),40(27,43); Z=-3. 523,P<0. 01) were significantly higher than those before intervention. Compared with the control group,the experimental group had significantly greater changes in the five regions:cognition(6(3,10),11(10,20); Z=-2. 821,P=0. 005),expression language (6(4,9),12(7,18); Z=-3. 278,P=0. 001),receptive language(5(3,10),12(7,18); Z=-3. 299,P=0. 001),fine motor (7(1,10),13(10,22); Z=-3. 038,P=0. 002)and gross motor(1(0,10),11(5,16);Z=-2. 568,P=0. 01) of PEP-3 after intervention. Conclusion Both conventional intervention and ESDM intervention can improve the cognitive,expression language,receptive language,imitation and fine motor abili-ty of children with ASD aged from 2 to 5 years,but ESDM intervention is more effective on improving the cog-nitive,language,imitation and fine motor ability of children with ASD.

Objective: To explore the relationship between serum 25-hydroxyvitamin D levels and core symptoms of autism spectrum disorder (ASD) in children. Method: In this cross-sectional study, ASD children 4 to 6 years of age who were diagnosed in Department of Developmental and Behavioral Pediatrics, First Hospital of Jilin university from January to May 2017 were assigned to ASD group, and children for routine growth and development assessment in Jilin province were assigned to control group. The two groups were well matched for age and sex, and none of them had received vitamin D supplementation. Serum 25-hydroxyvitamin D levels were measured by HPLC-MS/MS method. The patients of the ASD group were assessed with autism behavior checklist (ABC), childhood autism rating scale (CARS), social response scale (SRS), and autism treatment evaluation checklist (ATEC). The levels of vitamin D were divided into normal(>0.03 ng/L), insufficient (0.01-0.03 ng/L) and deficient (<0.01 ng/L). Levels of serum vitamin D between the two groups were compared by two independent sample t-test, and the difference in the percentages of normal, insufficient and deficient levels of vitamin D was tested by chi-square test, and correlations between vitamin D levels and the total scores or subscales of ABC, CARS, SRS and ATEC were analyzed by Pearson correlation analysis. Result: The 87 subjects in the ASD group included 75 males and 12 females, with a mean (±SD) age of (4.7±0.7) years. The 301 subjects in the control group included 249 males and 52 females, with a mean (±SD) age of (4.8±0.8) years. Serum vitamin D level in ASD children was significantly lower than that of the control group ( (0.021±0.008) vs. (0.036±0.016) ng/L, t=-8.17, P<0.01), and the between-group percentage difference of normal, insufficient and deficient levels of vitamin D was statistically significant (12 (14%) vs. 186 (62%) , 67 (77%) vs. 113 (37%) , 8 (9%) vs. 2 (1%) , χ²=72.1, P<0.01). There were negative correlations between serum vitamin D level in ASD children and total ABC score or ABC subscale scores (body behavior, self-care, language and social interaction)(r=-0.531,-0.397,-0.283,-0.248,-0.262, P=0.000, 0.000, 0.007, 0.020, 0.014). There were negative correlations between serum vitamin D level in ASD children and total CARS score and CARS subscale scores (imitation, nonverbal communication and general impression) (r=-0.352, -0.216, -0.248, -0.216, P=0.001, 0.046, 0.021, 0.046). There were negative correlations between serum vitamin D level in ASD children and SRS behavior subscale or ATEC social interaction subscale (r=-0.536, P=0.005, r=-0.400, P=0.014). Conclusion Serum 25-hydroxyvitamin D level in children with ASD is obviously lower than that in the healthy control group, and there are negative correlations between vitamin D levels and core symptoms of ASD.

Early start denver model(ESDM)is a comprehensive early intervention approach for the children with autism spectrum disorder(ASD)between 12-month-old-36-month-old.The model is built upon the theoretical foundations of applied behavior analysis,denver model(DM),and pivotal response treatment,and it is one of the naturalistic developmental behavioral interventions.Compared with the other early intervention methods,ESDM is not limited by the environment of intervention;it encompasses all the areas of development during teaching practice and has been widely adopted for the early intervention of the children with ASD,and achieves the satisfactory therapeutic effect.The ESDM typically uses an intensive one-on-one intervention approach,but variabilities have emerged in its practical application,such as group ESDM(G-ESDM),parent-implemented ESDM(P-ESDM),and peer-mediated ESDM.In particular,G-ESDM and P-ESDM have provided the learning opportunities for more families,showing a broad application prospect.This study reviews the theoretical foundations,teaching models,and the effects of various intervention modalities of the ESDM in the treatment of ASD;combined with the domestic and international research findings,this study offers a reference for further studies on the mechanism of ESDM intervention for ASD.
