Functional connectivity analysis of sensory motor network in patients with bipolar disorder type Ⅰ / 中华行为医学与脑科学杂志

Objective:To analyze the functional connectivity (FC) characteristics of sensory motor network (SMN) in patients with bipolar disorder type Ⅰ (BD-Ⅰ) by independent component analysis (ICA), and explore the correlation between abnormal SMN and clinical symptoms.Methods:Eighteen patients with BD-Ⅰ (BD-Ⅰ group) and 20 matched normal controls (HC group) were included.Both groups received resting state fMRI (rs-fMRI) scanning.Based on ICA-fMRI data, one-sample t-test and two-sample t-test were used to analyze the components of SMN and to explore abnormal brain regions between the two groups.Functional network analysis (FNC) was also used to explore the functional connectivity between SMN and other brain networks.Pearson correlation analysis were conducted by SPSS 17.0 to measure the potential associations between intra-and inter-network functional connectivity and age, education, score of Bech-Rafaelsen mania rating scale (BRMS), score of positive and negative syndrome scale (PANSS) and other indicators. Results:In BD-Ⅰ group, the functional connection in the right paracentral lobule (MIN: x=8, y=-32, z=68, t=4.86, P<0.001) and the right postcentral gyrus (MIN: x=41, y=-26, z=53, t=3.33, P<0.001) in SMN were higher than those in HC group.Compared with HC group, the connectivity value in patients with BD-Ⅰ increased between SMN-DAN (0.247±0.073, -0.078±0.080, t=-2.974, P<0.01, FDR adjusted), while the connectivity value decreased between SMN-DMN(-0.037±0.054, 0.272±0.067, t=3.520, P<0.01, FDR adjusted) and between SMN-rFPN(-0.034±0.055, 0.231±0.070, t=2.939, P<0.01, FDR adjusted). Conclusion:The sensorimotor network of patients with BD-Ⅰ has abnormal functional connections within and between networks, and FC values in some networks are positively correlated with manic symptoms, which may be part of the neural mechanisms of patients with BD-Ⅰ.

Relationship between cognitive fusion, empirical avoidance and obsessive-compulsive symptoms in patients with obsessive-compulsive disorder / 中华行为医学与脑科学杂志

Objective To compare the difference of cognitive fusion,empirical avoidance between patients with obsessive-compulsive disorder and healthy control group,and to explore the relationship between obsessive-compulsive score and cognitive fusion,empirical avoidance.Methods The cognitive fusion questionnaire(CFQ),acceptance and action questionnaire-2nd edition (AAQ-Ⅱ) and Yale-Brown scale for obsessive-compulsive symptoms (Y-BOCS) were used to investigate 100 subjects with obsessive-compulsive disorder (OCD) and 166 healthy controls.And the differences in cognitive fusion and empirical avoidance scores were compared between the two groups.The relationship of obsessive-compulsive symptoms and cognitive fusion,empirical avoidance was analyzed using multiple linear regression analysis.Results The scores of cognitive fusion ((49.89± 10.62) vs (33.88 ± 11.44),t =-11.345,P＜ 0.01) and empirical avoidance ((29.75±9.53) vs (21.59±7.03),t=-7.995,P＜0.01) in obsessive-compulsive disorder group were significantly higher than those in healthy control group.There were significant differences in cognitive fusion and empirical avoidance in age variables (F=8.63,P＜0.01).In AAQ-Ⅱ,item 2 (r=0.246,P＜ 0.05),item 6 (r=0.223,P＜0.05) and total score (r=0.240,P＜0.05) were positively correlated with the total score of Y-BOCS.Item 2 (r=0.311,P＜0.01),item 3 (r=0.286,P＜0.05),item 6 (r=0.248,P＜0.05) and total score (r=0.229,P＜0.05) were positively correlated with the scores of obsessive-thinking.In CFQ,item 2 (r=0.231,P＜0.0) 5),item 4 (r=0.242,P＜ 0.05),item 7 (r =0.308,P＜ 0.05),item 8 (r =0.277,P＜0.05) and item 9 (r=0.249,P＜0.05) were positively correlated with the total score of Y-BOCS.Item 8 (r=0.261,P＜0.05) was positively correlated with the scores of obsessive-thinking,item 7 (r=0.237,P＜0.05) and item 9 (r=0.238,P＜0.05) were positively correlated with scores of obsessive-compulsive behavior.When predicting total obsessive-compulsive scores,only CF item 7 of Q (B=1.827,P＜0.01),item 3 (B=0.956,P＜0.05),and item 6 of AAQ-Ⅱ (B=0.584,P＜0.05) entered the equation with a joint explanatory variation of 19％.When predicting the score of obsessive-thinking,only item 2 of AAQ-Ⅱ (B=0.446,P＜0.01) entered the equation,explaining the variance was 9.7％.In the prediction of obsessive-compulsive behavior,only item 9 (B=0.815,P＜0.05) of CFQ entered the equation,and the explanatory variation was 5.6％.Conclusion Cognitive fusion in the patients with obsessive-compulsive disorder and the high level of empirical avoidance may be an important factor for the maintenance of the symptoms.

Transcatheter closure of congenital heart defects in 16 cases using domestic-made occluders / 中国组织工程研究

Sixteen patients with congenital heart disease,4 males,12 females,aged 5-52 years,admitted to Department of Cardiology,Tianchang People's Hospital from October 2007 to November 2008 were retrospectively analyzed.All patients were diagnosed by echocardiography as 4 with congenital patent ductus arteriosus(PDA),6 atrial septal defect(ASD) and 6 ventricular septal defect(VSD).The diameter limitation of PDA,ASD and VSD are 5-17 mm,20-32 mm,and 4-10 mm,respectively.All patients received transcatheter-closure therapy by domestic-made occluders,and diameters of PDA,ASD and VSD were monitored using angiography and echocardiography.The treatment effect was evaluated by echocardiography 72 hours after procedure.The closure rate was 100%,without severe complications.No residual shunt was observed 72 hours after procedure.Four patients developed fever,including 2 acute respiratory infection and 2 pulmonary infection with balanced anesthesia;1 patient with ASD and 2 with VSDs developed arrhythmia.Results suggest that transcatheter closure of congenital heart defects(PDA,ASD and VSD) using domestic-made occluders is safe and effective according to strict indications.

Results:The ATQ attained good psychometric properties: Cronbach α of ATQ was 0.95, spit-half correlations ranged from 0.90 to 0.94; correlation coefficient between ATQ and BDI was 0.54 for normal undergraduates, 0.60 for schizophrenics, and 0.75 for depressive subjects (p<0.001). There were significant difference among non-depressed undergraduates、depressed undergraduates、schizophrenics and depressive patients. Conclusion: The present study provided empirical support for the reliability and validity of ATQ.
