OBJECTIVEWe aim to explore the central auditory nervous system (CANS) functioning in children with nonsyndromic cleft palates by analyzing the auditory evoked potentials and event-related potentials (ERP).

METHODSA total of 34 children with nonsyndromic cleft palates were recruited as subjects, and 27 normally developed children were selected as the normal controls. Auditory brainstem response (ABR), middle latency response (MLR), and mismatch negativity (MMN) of ERP were selected as indices to observe the function of CANS in children in both groups.

RESULTSAstatistically significant difference between the groups was obtainedin the MMN recording (F = 227.69, P < 0.01), whereas no significant group differences were obtained in the ABR and MLR results (P > 0.05). Children with nonsyndromic cleft palates showed diminished MMN responses compared with the normal controls, whereas ABR and MLR were within the normal range.

CONCLUSIONChildren with nonsyndromic cleft palates are at risk of central auditory discrimination dysfunction. The significant abnormal event-related potentials recorded in children with cleft palates suggest that the dysfunction of CANS maybe located at the cortical level and normal function of CANS was located at the brain stem and sub-cortical level.

Objective: To examine the association between inflammatory cytokines and arrhythmias using two-sample bidirectional Mendelian randomization (MR) approach, so as to provide the basis for the prevention and treatment of arrhythmias. Methods: Data of 91 types of inflammatory cytokines were collected from a meta-analysis of genome-wide association studies (GWAS), and data of 7 types of arrhythmia were collected from GWAS database of susceptibility genes. A forward MR analysis was performed using the inverse variance weighted method with inflammatory cytokines as exposure and arrhythmias as the outcome, and a reverse MR analysis was performed with arrhythmias as exposure and inflammatory cytokines as the outcome. The positive and negative direction of association was evaluated using MR Steiger test. The sensitivity analysis were assessed using the Cochran's Q test, MR-PRESSO test and MR-Egger regression. Results: Forward MR analysis results showed that fractalkine (OR=1.231), fibroblast growth factor 5 (OR=1.105) and tumor necrosis factor (TNF)-related activation cytokine (OR=0.848) were statistically associated with ventricular arrhythmias (all P<0.05). CD40L receptor (OR=0.970), fibroblast growth factor 5 (OR=1.071), FMS-related tyrosine kinase 3 ligand (OR=0.958), and monocyte chemotactic protein-2 (OR=1.020) were statistically associated with atrial fibrillation (all P<0.05). TNF-related activation cytokine (OR=1.125) was statistically associated with paroxysmal tachycardia (P<0.05). Interleukin-15 receptor subunit α (OR=1.001) was statistically associated with bradycardia (P<0.05). C-C motif chemokine ligand 28 (OR=1.974) and interleukin-7 (OR=1.738) were statistically associated with right bundle branch block (both P<0.05). TNF superfamily member 14 (OR=0.784) was statistically associated with left bundle branch block (P<0.05). CXC motif chemokine ligand 11 (OR=1.277), interleukin-12B (OR=1.127), matrix metalloproteinase-1 (OR=1.333), stem cell factor (OR=0.874), and TNF-β (OR=1.152) were statistically associated with atrioventricular block (all P<0.05). Cochran's Q test detected no heterogeneity, and neither the MR-Egger regression nor the MR-PRESSO test revealed horizontal pleiotropy of instrumental variables (all P>0.05). Reverse MR analysis showed no association between gut microbiota and constipation (all P>0.05). Conclusion Among the 91 types of inflammatory cytokines, 12 types were associated with increased risk of arrhythmias and 5 types were associated with decreased risk of arrhythmias.

Objective To access the left ventricular sysytolic function in children at acute stage of Kawasaki disease using speckle-tracing imaging. Methods Two-dimensional echocardiograghic images of 27 patients and 19 normals were collected in apical long-axis view, two-champer view, four-champer view, short-axis views at the levels of mitral annulus, papillary muscle and apex. The systolic peak values of longitudinal strain, radial strain and circumferential strain were measured by speckle-tracking imaging. Results Compared with controls the values of longitudinal strain and radial strain are lower in most segments in patients(P < 0.05). There were no significant differences between the patients and controls in circumferential strain(P>0.05). Longitudinal strain and radial strain measured were lower in 8 patients with coronary ectasia(including 7 cass with coronary artery aneurysms in vessels) than other 19 patients,but the two groups have no significant differences(P>0.05). Conclusions Long-axis and short-axis function of the heart decreased regardless of coronary artery ectasia.

Objective:To explore the relationship of negative life events,parent-child relationship,teacher-child relationship with the altruistic prosocial behaviors in migrant and unattended primary school children. Methods:Totally 1198 migrant children and 1631 unattended children were recruited. The dimension ofaltruistic prosocial behaviorof Child and Adolescent Prosocial Behavior Questionnaire (CAPBQ-A)was used to evaluate altruistic prosocial behaviors,Life Event Questionnaire (LEQ)was used to evaluate negative life events,parent trust and support dimensionof Social Psychological Relationship Questionnaire(SPRQ-P)to evaluate par-ent-child relationship, and teacher trust and support dimension (SPRQ-T ) to evaluate teacher-child relationship. Results:The CAPBQ-A scores were higher in migrant children than in the unattended children (P<0. 001). Being migrant or unattended children (β=-0. 07),LEQ score (β=-0. 04),SPRQ-P score (β=0. 13) and SPRQ-T score (β=0. 31 )predicted the CAPBQ-A score significantly. The SPRQ-P score had significantly stronger predictive effect on the migrant children compared to the unattended children (β=-0. 06 ). Yet the SPRQ-T score predicted the unattended children stronger (β=0. 06 ,Ps<0. 0 1 ). Conclusion:The unattended children's al-truistic prosocial behaviors are much worse than the migrant children. Personal relationships seem to play a more important role than negative life events in shaping children's altruistic prosocial behaviors. Moreover,the parent-child relationship seems to be more important to the migrant children,whereas the teacher-child relationship is more important to the unattended children.

The myocardial viability after myocardial infarction was evaluated by intravenous myocardial contrast echocardiography. Intravenous real-time myocardial contrast echocardiography was performed on 18 patients with myocardial infarction before coronary revascularization. Follow-up echocardiography was performed 3 months after coronary revascularization. Segmental wall motion was assessed using 18-segment LV model and classified as normal, hypokinesis, akinesis and dyskinesis. Viable myocardium was defined by evident improvement of segmental wall motion 3 months after coronary revascularization. Myocardial perfusion was assessed by visual interpretation and divided into 3 conditions: homogeneous opacification; partial or reduced opaciflcation or subendocardial contrast defect; contrast defect. The former two conditions were used as the standard to define the viable myocardium. The results showed that 109 abnormal wall motion segments were detected among 18 patients with myocardial infarction, including 47 segments of hypokinesis, 56 segments of akinesis and 6 segments of dyskinesis. The wall motion of 2 segments with hypokinesis before coronary revascularization which showed homogeneous opacification, 14 of 24 segments with hypokinese and 20 of 24 segments with akinese before coronary revascularization which showed partial or reduced opaciflcation or subendocardial contrast defect was improved 3 months after coronary revascularization. In our study, the sensitivity and specificity of evaluation of myocardial viability after myocardial infarction by intravenous real-time myocardial contrast echocardiography were 94.7% and 78.9%, respectively. It was concluded that intravenous real-time myocardial contrast echocardiography could accurately evaluate myocardial viability after myocardial infarction.

By using a yeast two-hybrid system, a yeast two-hybrid bait vector was constructed and identified for screening of the HPV18 E6-interacting proteins, and its effects on the growth of yeast cells and the activation of reporter genes were investigated. Total mRNA extracted from Hela cells was reversely transcribed into cDNA. Fragment of HPV18 E6 cDNA was amplified using RT-PCR and directly ligated to the pGBKT7 vector. The recombinant plasmid was confirmed by restriction endonuclease analysis and DNA sequencing. The recombinant pGBKT7-HPV18 E6 plasmid and empty pGBKT7 vector were transformed into the yeast cell AH109, respectively. After they were cultured respectively in YPDA liquid medium and nutrition-deficient culture medium, their toxicity and transcriptional activation were tested by both the phenotype assay and the color assay. The bait plasmid HPV18 E6 was successfully obtained. After being cultured in YPDA liquid medium for 16h, the A (600 nm) values of two yeast fluids were 0.98+/-0.03 and 0.99+/-0.02, respectively. The recombinant pGBKT7-HPV18 E6 plasmid and empty pGBKT7 vector could grow to white colonies on SD/-Trp/X-alpha-gal plates, while no colony could survive on SD/-His/-Trp/X-alpha-gal, SD/-Ade/-Trp/X-alpha-gal plates, indicating that the bait plasmid pGBKT7-HPV18 E6 was constructed successfully and expressed correctly, and could not activate the transcription of reporter gene alone. The yeast two-hybrid GAL4 system 3 can be utilized to find HPV18 E6 interacting proteins.
