Objective To investigate the point prevalence rate of social anxiety disorder (SAD) in Chengdu primary school, and analyze the influencing factors. Methods Data came from a large representative sample of Chengdu 1441 primary school students, who were selected by stratified cluster sampling methods. They then finished self-compiled questionnaire, strengths and difficulties questionnaire, Eysenck Personality Inventory (EPI) (age 7 ~ 15 ), Egma Minnen ay Bardndosnauppforstran (EMBU) respectively. And then they had the face to face interviews with the trained psychiatrists, according to development and well - being assessment ( DAWBA,Chinese Version). Results Among 1441 Chengdu primary students, 37 of them were diagnosed SAD,with a point prevalence of 2.6% totally. The point prevalence was different in each grades, for 2.7% in grade 3,4. 1% in grade 4,4.1% in grade 5,3.5% in grade 6( z= -2.3, P=0. 023 ). Compared with the normal counterparts ,the SAD students had statistically significance different in pro-socialization ( z = -2. 1, P = 0.035 ), affection(z=- 5.2, P = 0. 001 ) , moral conduct ( z = - 2.8, P = 0. 004 ), peer( z = - 3.1, P = 0.002 ), excessive interference of maternal education ( z = - 3.1, P = 0.002 ), introversion-extroversion ( z = - 2. 0, P = 0. 046 ), neuroticism ( z =- 3.5, P= 0. 000), concealing tendency ( z= - 2.3, P= 0.018 ). Logistic regression analysis showed that: grade,family location, habitual lifestyle over the past years more emotional problem and excessive interference of maternal education were related with SAD occurrence. Conclusion The point prevalence rate of social anxiety disorder among Chengdu primary students is 2.6% ,and it was influenced by a number of factors .

Objective To investigate the efficacy and white matter integrity of low frequency repetitive transcranial magnetic stimulation (rTMS) and the modified electroconvulsive therapy (MECT) in patients with schizophrenia. Methods From May 2015 to October 2016,120 cases with schizophrenia were randomly enrolled into the MECT group and of the rTMS group. Patients in the MECT group were treated with the modified electric convulsive therapy for 8 times ,while patients in the rTMS group were treated with the repetitive transcranial magnetic stimulation for 12 times. PANSS were used to evalue the clinical effects. Repeatable battery for the assess-ment of neuropsychological status was used to assess the cognitive function. Treatment emergent side-effect scale was used to assess the adverse effects. Brain fractional anisotropy was used to assess white matter integrity. Results After treatment,the PANSS scores were significantly lowered,however,the RBANS scores were signifi-cantly higher in the MECT group and rTMS group than those before treatment ,with significant differences (P <0.05). No significant differences for the PANSS scores and the RBANS scores were observed between the two groups before and after treatment. There was no significant difference for the TESS scores between the two groups before treatment(P > 0.05). After treatment,the TESS scores in the MECT group were significantly higher than those in the rTMS group(P < 0.05). After treatment,the FA values of left anterior cingulate gyrus,left posterior cingulate gyrus ,left prefrontal cortex and genu of corpus callosum for both MECT group and rTMS group were significantly increased (P < 0.05 ,respectively). Compared with the MECT group ,the FA value significantly increased in the rTMS group after treatment (P < 0.05). Conclusions Both MECT and rTMS have significant clinical efficacies and can improve the cognitive function of schizophrenics. rTMS is more safe than MECT ,with a stronger effect on preventing the integrity of white matter than MECT.

Objective To evaluate the feasibility of secondary transplantation for patients with acute leukemia after failure of the first haploidentical hematopoietic stem cell transplantation. Methods Two acute leukemia patients underwent the first haploidentical hematopoietic stem cell transplantation from two donors with thalassemia, and the number of collected CD34+ cells was 2.57×106/kg and 1.99×106/kg per donor, respectively. The first haploidentical hematopoietic stem cell transplantation failed. Secondary transplantation was performed from two non-thalassemia donors, and the number of collected CD34+ cells was 4.28×106/kg and 5.75×106/kg per donor, respectively. A reduced-intensity conditioning regimen consisting of fludarabine (Flu), busulfan (Bu) and antithymocyte globulin (ATG) was adopted for the secondary transplantation. Results For two recipients, the time of secondary transplantation of neutrophil and platelet was +12 d and +10 d, +10 d and +10 d, respectively. Up to the final follow-up (+1 062 d and +265 d after secondary transplantation), the primary diseases of both two recipients have been completely relieved without evident post-transplantation complications. Conclusions Secondary transplantation with reduced-intensity conditioning regimen may successfully treat acute leukemia after failure of the first haploidentical hematopoietic stem cell transplantation.

OBJECTIVETo explore common biological pathways for attention deficit hyperactivity disorder (ADHD) and low birth weight (LBW).
METHODSThei-Gsea4GwasV2 software was used to analyze the result of genome-wide association analysis (GWAS) for LBW (pathways were derived from Reactome), and nominally significant (P< 0.05, FDR< 0.25) pathways were tested for replication in ADHD.Significant pathways were analyzed with DAPPLE and Reatome FI software to identify genes involved in such pathways, with each cluster enriched with the gene ontology (GO). The Centiscape2.0 software was used to calculate the degree of genetic networks and the betweenness value to explore the core node (gene). Weighed gene co-expression network analysis (WGCNA) was then used to explore the co-expression of genes in these pathways.With gene expression data derived from BrainSpan, GO enrichment was carried out for each gene module.
RESULTSEleven significant biological pathways was identified in association with LBW, among which two (Selenoamino acid metabolism and Diseases associated with glycosaminoglycan metabolism) were replicated during subsequent ADHD analysis. Network analysis of 130 genes in these pathways revealed that some of the sub-networksare related with morphology of cerebellum, development of hippocampus, and plasticity of synaptic structure. Upon co-expression network analysis, 120 genes passed the quality control and were found to express in 3 gene modules. These modules are mainly related to the regulation of synaptic structure and activity regulation.
CONCLUSIONADHD and LBW share some biological regulation processes. Anomalies of such proces sesmay predispose to ADHD.
