Interhemispheric functional connectivity in patients with positive symptoms of schizophrenia: a resting-state functional magnetic resonance imaging study / 中国神经精神疾病杂志

Objective To investigate functional connectivity between the two hemispheres in patients with positive symptoms of schizophrenia using voxel-mirrored homotopic connectivity ( VMHC ) based on resting-state functional magnetic resonance imaging (rs-fMRI). Methods Eighteen patients with positive symptoms of schizophrenia and 22 healthy controls underwent the rs-fMRI. The whole brain VMHC was calculated in order to provide imaging basis for the study of the pathological mechanism of schizophrenia. Results Compared to the controls, VMHC values were decreased in the bilateral orbitofrontal cortex (t=-5.31, P<0.01), fusiform gyrus (t=-5.16, P<0.01), middle occipital gyrus (t=-5.31, P<0.01) in patients with positive symptoms of schizophrenia. Conclusion The functional coordination between homotopic brain regions is impaired in patients with positive symptoms of schizophrenia .

Effect of health education on blood pressure control in hypertensive population from a community of Wuzhou city / 心血管康复医学杂志

Objective:To study effect of health education on blood pressure control in patients with hypertension through community survey and perform health education.Methods:Residents from Datang street community re-ceived systematic sampling and questionnaire.A total of 490 patients with hypertension detected during census were regarded as subjects,and they were randomly divided into routine treatment group (n=240)and health education group (n=250).Health education group received health education,and effects were compared between two groups. Results:Compared with routine treatment group after intervention,there were significant rise in awareness rate of preventive and therapeutic knowledge [diagnostic value of hypertension (49.17% vs.58.40%),risk factors of hy-pertension (30.41% vs.58.00%),antihypertensive medication (58.75% vs.79.60%)]and control rate of blood pressure (23.33% vs.60.80%),and significant reduction in blood pressure [(147.68±13.97)/(89.30±12.43)mm-Hg vs.(143.57±13.53)/(85.73±11.54)mmHg]in health education group,P<0.05 or<0.01. Conclusion:Carry-ing out targeted health education possesses active significance for prevention and treatment of hypertension.
