Objective: To explore the impact of stage recovery training on children with autism spectrum disorder, and to provide reference for the scientific and rational rehabilitation and recovery training plans. Methods: A total of 59 children with autism spectrum disorder in Luzhou were recruited and randomly divided into control group, intervention group Ⅰ and intervention group Ⅱ for 4 stages of T1-T4 recovery training. Before and after the training, Autism Behavior Checklist(ABC) was used to assess child s sensation, language, motor, communication and self care ability. Results: There was no significant difference in the overall score of the ABC among the three groups in T1 and T2 stages ( P >0.05), but there was significant difference in T3 and T4 stages ( F= 3.98, 5.09, P < 0.05), which showed the intervention group Ⅰ and Ⅱ were lower than the control group. In terms of dimensions, in addition to the insignificant difference in language scores ( P >0.05), there were significant differences in feeling, communication, movement, and self care scores ( P <0.05). Overall score of the ABC in intervention group I and group II was lower than the control group ( P <0.05). Compared with the control group, the overall scores of children in intervention Ⅰ and intervention Ⅱ were significant in both T3 and T4 stages ( P <0.05). Compared with T1 stage, there were no significant differences in the overall scores of children in the control group in T2 stage, T3 stage and T4 stage ( P >0.05), while significant difference was observed in the intervention group Ⅰ and group Ⅱ in T2-T4 stage ( P <0.05). Conclusion Stage recovery training might help to alleviate the overall symptoms of children with autism spectrum disorder in sensation, communication, motor development and self care behaviors. The stage recovery training focusing on physical exercise can effectively alleviate the physical function of the child, while those focusing on social interaction is more conducive to improving child s social ability.

Objective:To investigate the overall clinical performance of nursing students and analyze its influencing factors to provide evidence for the improvement.Methods:A questionnaire survey was carried out among 288 nursing students from Qilu Hospital of Shandong University in March to May 2020. The survey included a general data questionnaire, Holistic Clinical Assessment Tool, Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale, Medical Student Safety Attitudes and Professionalism Survey of nursing students.

Results:The total score of Holistic Clinical Assessment Tool was 114.95 ± 22.91. The total score of Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale was 156.70 ± 26.98. The total score of Medical Student Safety Attitudes and Professionalism Survey was 123.65 ± 31.00. The influencing factors included social practice experience and clinical learning environment, which accounted for 28.0% of the total variation of overall clinical performance of nursing students.Conclusions:Educators and managers of nursing students' schools and internship hospitals should actively explore the educational reform practice to promote the improvement of clinical ability, so as to promote the improvement of the overall clinical ability of nursing students.

OBJECTIVE: To verify a rare allele of human leukocyte antigen (HLA) and analyze its inheritance and 3D molecular structure. METHODS: PCR-sequence-based typing, PCR-single strand oligonucleotide polymorphism and single allele-specific sequencing were carried out to characterize the rare HLA-C allele and its transmission in the family. Its protein structure was modeled by using SWISS-MODEL, Phyre2 and FATCAT software. RESULTS: Analysis indicated that the rare allele (HLA-C*08:84) has transmitted from the proband's mother and has differed from HLA-C*08:01 by a single base (g.512G>C), resulting in substitution of an amino acid (p.Trp147Ser). Modeling of the 3D structure of the encoded protein indicated that the amino acid residue variation is located at the alpha 2 helix, which participates the formation of pocket F. Modeling of the structures of C*08:84, C*08:01, C*08:02, C*08:03 and C*08:22 has suggested significant variation in the peptide binding regions of the backbone, with root mean square errors being 1.70 nm, 1.79 nm, 0.71 nm and 1.70 nm, respectively. CONCLUSION A rare HLA-C*08:84 allele has been identified, and its clinical significance has been analyzed.

To explore the way of prenatal echocardiography in the diagnosis of fetal double aortic arch . Methods T he data of fetuses diagnosed as double aortic arch in 6 prenatal centers in Hunan in echocardiograms performed at 20－36 weeks of gestation from 2013 to 2018 were reviewed . T he characteristics of echocardiographic with double aortic arch , and the associated malformations were observed ,the clinical outcome were analyzed . Results T he main echocardiographic features of the double aortic arch were three‐vessel‐tracheal view s ,which showed a bifurcation of the ascending aorta and a ring consisted of aortic right and left arch . From this retrospective analysis , 29 double aortic arches were identified ,which 8 cases ( 28% ) combined with cardiac defect and extracardiac abnormalities , 1 case with 22q11 deletion . Among them ,5 cases were confirmed by autopsy ,24 cases were diagnosed by computed tomography angiography ( 8 cases were confirmed by operation ) . Conclusions Systematic prenatal echocardiography in the diagnosis of fetal double aortic arch has significant clinical value in the cliagnose of double aortic arch ,w hether it is associated with other malformations and is important for assessing fetal prognosis .

OBJECTIVE: To compare the effect of 7 antipsychotic drugs on the life quality of schizophrenia patients including chlorpromazine, sulpiride, clozapine, risperidone, olanzapine, quetiapine, and aripiprazole. METHODS: A total of 1,227 stable schizophrenic patients within 5 years onset who took 1 of the 7 study medications as maintenance treatment were followed up for 1 year at 10 China sites. Patients were evaluated by the short form-36 health survey (SF-36) at the baseline and at the end of 1 year. RESULTS: The life quality was improved obviously at the end of the follow-up. There was significant difference in body pain, vitality, and mental health (P<0.05) among these antipsychotic drugs. CONCLUSION All 7 antipsychotic drugs can improve the life quality of schizophrenia patients. Atypical antipsychotic drugs, especially olazapine and quetiapine, are superior to typical antipsychotic drugs in improving life quality.

【Objective】 To explore the association of HLAII(-DRB1, -DQB1, -DPB1) alleles and haplotypes polymorphisms with acute myeloid leukemia (AML) in northern Han population. 【Methods】 A total of 308 AML (non-M3) patients (patient group) and 824 unrelated healthy bone marrow donors (control group) were genotyped at a high-resolution level using polymerase chain reaction-sequence-based typing (PCR-SBT), next-generation sequencing (NGS) with Ion Torrent S5 platform and sequence specific oligonueleotide probes (SSO) with LABScan^® 3D platform. Frequencies of HLA II alleles and haplotypes were calculated with Arlequin 3.5.2.2 software. The odds ratio (OR) of AML was also calculated for case-control study. 【Results】 By χ² test and correction, an increased frequency of HLA-DRB1^*07∶01(14.61% vs 9.53%, P<0.01), HLA-DQB1^*02∶02(12.82% vs 8.31%, P<0.01), HLA-DQB1^*06∶02(11.53% vs 8.74%, P<0.05) and HLA-DPB1^*17∶01(5.84% vs 3.16%, P<0.01) among AML patients was discovered in significant comparison with the control group. After Bonferroni correction, the frequency of HLA-DRB1^*07∶01(Pc<0.05), HLA-DQB1^*02: 02(Pc<0.05) and HLA-DPB1^*17∶01(Pc<0.05) in AML patients were still higher than those in the control group, which had a strong positive correlation with AML (OR=1.62 (95% CI=1.23~2.14), 1.62(95% CI=1.21~2.18) and 1.91(95% CI=1.23~2.94), respectively. The frequency of two loci haplotype HLA-DRB1^*07∶01-DQB1^*02∶02 in AML patients was still higher than that of the control group after Bonferroni correction (12.66% vs 8.19%, Pc<0.05). The frequency of the 3 loci haplotype HLA-DRB1^*07∶01-DQB1^*02∶02-DPB1^*17∶01, as a susceptible haplotype of AML, was higher than that of the control group and was strongly correlated with AML. 【Conclusion】 The data on the association of HLA II (-DRB1, -DQB1, -DPB1) alleles and haplotype polymorphisms with AML in northern Han populations was obtained in this study. HLA-DRB1^*07∶01, HLA-DQB1^*02∶02, HLA-DPB1^*17∶01 and the HLA-DRB1^*07∶01-DQB1^*02∶02-DPB1^*17∶01 haplotype are the risk genes and susceptible extended haplotype for AML. The risk prediction based on HLA haplotype might be more accurate than that based on single allele.
