Objective To understand the application effect of early screening scale and behavioral intervention effect in children with autism spectrum disorder (ASD). Methods A total of 348 children with suspected ASD were selected and evaluated using the Modified Checklist for Autism in Toddlers (M-CHAT) and Autism Behavior Checklist (ABC). The evaluation results were compared with those from the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Children enrolled were given Early start Denver model (ESDM) intervention. The evaluation results of Gesell Developmental Scale and Autism Treatment Evaluation Checklist (ATEC) scores were compared before and after intervention. Results The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating ASD in children aged 1-3 years were 89.53%, 90.70%, 89.92% and 0.78. The corresponding values of ABC were 78.49%, 81.40%, 79.46% and 0.56. The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating children aged >3-6 years were 87.30%, 77.78%, 84.44% and 0.64. The corresponding values of ABC were 85.71%, 77.78%, 83.33% and 0.62. The sensitivity and accuracy of M-CHAT were higher than ABC for evaluating ASD in children aged 1-3 years (P<0.05). There were no significant differences in sensitivity, specificity and accuracy between M-CHAT and ABC for evaluating ASD in children aged 3-6 years (P>0.05). After intervention, development quotients (DQ) of personal-social aspects, adaptability, language, gross motor, and fine motor of children with ASD were higher than those before intervention (P<0.05). ATEC scores for language, behavior, sensation, and social contact of children with ASD were lower than those before intervention (P<0.05). Conclusion M-CHAT and ABC both can be used for early screening of ASD in children, especially M-CHAT. Early behavioral intervention can effectively improve the condition and developmental level of children with ASD.

Background The course of schizophrenia is prolonged,and patients have impaired social function and significantly reduced quality of life.Drug therapy combined with psychological therapy is particularly important for improving the quality of life of patients.Brief cognitive behavioral therapy(BCBT)has been widely applied in clinical practice,but current research on BCBT focuses more on improving patients' symptoms and lacks relevant reports on improving quality of life.Objective To evaluate the efficacy and influencing factors of BCBT combined with conventional treatment on improving the quality of life in patients with schizophrenia.Methods A total of 210 patients who met the diagnostic criteria for schizophrenia in the International Classification of Diseases(10th edition)(ICD-10)and were followed up at the outpatient department of Beijing Anding Hospital Capital Medical University from August 2011 to December 2016 were selected.Using a random number table method,patients were divided into study group and control group,with 105 cases in each group.Both groups received routine treatment,and the research group received a total of 8 BCBT sessions for 12 weeks on this basis.At the baseline period and 12 weeks of treatment,26 weeks of follow-up and 52 weeks of follow-up,Positive and Negative Syndrome Scale(PANSS),Personal and Social Performance Scale(PSP)and World Health Organization Quality of Life Brief(WHOQOL-BREF)were used for evaluation.Results The results of repeated measures analysis of variance showed that the time point effect and interaction effect of PANSS total score were statistically significant(F=118.783,8.083,P<0.01).The time point effect,inter group effect and interaction effect of PSP total score were statistically significant(F=94.358,4.048,5.490,P<0.05 or 0.01).The time point effect,inter group effect and interaction effect of the total score of WHOQOL-BREF were all statistically significant(F=12.330,4.168,4.142,P<0.05 or 0.01)Binary Logistic regression analysis showed that the study group(OR=1.861,95%CI:1.004～3.448)and young age(OR=1.044,95%CI:1.001～1.088)were protective factors for improving quality of life of patients,while high PANSS baseline score(OR=0.972,95%CI:0.945～0.999)was a risk factor for improving quality of life of patients.Conclusion The combination of BCBT and conventional treatment has an earlier onset of improvement in the quality of life of patients with schizophrenia,and long-term efficacy is superior to conventional treatment.

Objective:To construct and purify four respiratory syncytial virus (RSV) PreF proteins through gene sequence design and optimization and evaluate their immunogenicity.Methods:Coronin-1A and T4 trimer protein gene sequences were optimized with Human and CHO codons, and then added to RSV F protein sequence. The above plasmids were transfected into Expi293F cells for protein expression. After purification by nickel column, four trimer proteins were prepared. SDS-PAGE and Western blot were performed for protein identification. BALB/c mice were immunized at week 0 and week 3, and blood samples were collected to measure the activities of binding and neutralizing antibodies in serum.Results:SDS-PAGE and Western blot showed that the four proteins had stable trimer structure. Antigen-antibody affinity test showed that the four trimer proteins had strong affinity with RSV-specific monoclonal antibodies 8897, D25, Motavizumab, AM14 and Palivizumab. The titers of antibodies induced by the two T4 trimers were higher after the initial immunization, while there was a substantial increase in the titers of antibodies induced by Human codon-optimized trimer protein after the second immunization.Conclusions:PreF trimer protein can be prepared by adding any of the two different heterotrimer motifs, and induce effective binding and neutralizing antibodies in mice.

Objective:To compare the immunogenicity of the prefusion (PreF) and postfusion (PostF) conformations of the respiratory syncytial virus (RSV) F protein.Methods:The expression of PreF and PostF recombinant proteins was analyzed by SDS-PAGE and Western blot. The binding affinity between F protein and its specific antibodies was detected by Octet. The binding antibodies and neutralizing antibodies in immune serum were detected after immunizing mice with PreF or PostF recombinant protein.Results:PreF protein was stable in the form of a trimer after modification with higher binding affinity with monoclonal antibodies such as D25, 8897, AM14, Palivizumab and Motavizumab. PostF protein lacked the antigenic site ? and showed a monomer conformation. Besides, it was unable to bind to D25, 8897 and AM14 antibodies. Animal experiments showed that AS01 adjuvant was better than aluminum adjuvant in inducing binding antibodies and neutralizing antibodies against RSV Long strains. The binding antibodies induced by PreF and PostF recombinant proteins had similar binding ability to PreF protein, while the binding antibodies induced by PostF recombinant protein showed stronger binding ability to PostF than to PreF.Conclusions:PreF has more epitopes and the trimer form of PreF recombinant protein after modification is more stable and can induce stronger neutralizing antibodies. Moreover, the immunopotentiating effect of AS01 adjuvant is better than that of aluminum adjuvant. Therefore, stabilization-based trimer structure modification of PreF and the development of adjuvants are crucial for the development of RSV vaccines.

Objective To study the effects of attenuated Salmonella(Ty21a-pIRES-IL-2-NK4,TPIN)carrying interleukin-2(IL-2)/4-kringle antagonist of hepatocyte growth factor(NK4)double gene on humoral and cellular immune function.Methods Eighteen BALB/c mice,half male and half female,were randomly divided into control group(1. 5 mL 10%NaHCO3 by gastric tube feeding),Ty21a group(0. 1 mL Ty21a by gastric tube feeding)and TPIN group(0. 1 mL TPIN by gastric tube feeding),with 6 mice in each group. The immunization was boosted twice 7 d after the initial immunization. At 21d after administration,the blood samples were collected from eyeballs and the serum was separated,which was detected for the serum IgG antibody level by ELISA. The thymus and spleen of mice were isolated aseptically,and the spleen cells were stimulated by Ty21a and TPIN respectively in vitro. After 72 h,the proliferation ability of spleen cells was measured by CCK-8 assay,and the expression level of cytokines in spleen cells was detected by ELISA. The spleen and thymus were weighed,the spleen and thymus indexes were analyzed,and HE staining was performed.Results Compared with the control group and Ty21a group,the serum IgG level(F = 111. 74,P < 0. 01)and the contents of IFNγ,IL-4 and IL-10 in spleen cell supernatant(F = 38. 21,11. 37 and 26. 92,respectively,each P < 0. 05)increased significantly,as well as the spleen and thymus indexes(F = 10. 419 and 5. 859,respectively,each P < 0. 05)showed significant increase. In mice of Ty21a and TPIN group,the thymus cortex widened,lymphocytes increased,and there was mild inflammatory reaction;the white pulp and lymphocytes in spleen increased with neutrophil infiltration.Conclusion TPIN has a good immune protective effect,and can significantly stimulate the body to produce humoral immunity and cellular immunity,which may have a good therapeutic effect on tumors.

ObjectiveTo construct traditional Chinese medicine （TCM） diagnostic scale of turbid toxin syndrome in order to provide corresponding reference for the standardization of TCM syndromes and studies. MethodsWe systematically searched the Chinese Medical Dictionary （CMD）， China Knowledge Network （CNKI）， Wanfang Data Knowledge Service Platform （WF） and VIP database for TCM classics and modern literature on turbid toxin syndrome， and initially screened the four diagnosis information of turbid toxin syndrome， established a pool of information entries， and conducted a cross-sectional clinical survey. Discrete trend method， correlation coefficient method， Cronbach's coefficient method， and factor analysis method were applied to objectively screen the entries. The diagnostic scale of turbid toxin syndrome were constructed through three rounds of Delphi method expert survey to determine the scale entries， using hierarchical analysis to get the judgement matrix scores and relative weight of each entry， after passing consistency test and then isometric expansion of the relative weight of the entries to get the weight of each entry and assign the value. ResultsA total of 35 articles were included， 45 entries were obtained after the initial screening. After the clinical investigation， 12 entries were not suitable by the discrete trend method， 23 entries not suitable by correlation coefficient method， 13 entries by the internal consistency screening were removed with the Cronbach's alpha coefficient rising， and 10 entries not suitable by the factor analysis method. Twenty-two entries were retained after objective screening by the combined use of the four statistical methods. The positive coefficients of experts in the three rounds of Delphi method of expert consultation were 96.67%， the coefficients of expert authority were 0.834， 0.856， and 0.867， and the coefficients of co-ordination were 0.126， 0.326， and 0.312， respectively. After consulting with clinical experts， and three rounds of Delphi method survey and hierarchical analysis method weight assignment， the diagnostic scale entries of turbid toxin syndrome were finally established. Primary symptoms： dark red or purple and dusky tongue， yellowish greasy or dry coating （10 points）； sticky and unpleasant stools （8 points）； disharmony of tastes including halitosis， sticky and greasy taste in the mouth， dry mouth and bitter taste in the mouth （6 points）； unfavourable or yellowish or red urination （5 points）； and dark complexion （4 points）. Secondary symptoms： heavy body （3 points）； dizziness （3 points）； profuse， sticky， foul-smelling secretions （2 points）； wiry and slippery， or slippery， or slippery and rapid pulse （2 points）； feeling of hardness in the abdomen （1 point）. ConclusionUsing Delphi method combined with the hierarchical analysis method， combining qualitative and quantitative study， a diagnostic scale of turbid toxin syndrome was initially developed.
