Current prevalence and correlates of depressive disorder among outpatients with essential hypertension from cardiovascular divisions of tertiary general hospitals / 中国神经精神疾病杂志

Objective To investigate the current prevalence of depressive disorder and the associated factors in pa?tients with essential hypertensive from cardiovascular divisions of tertiary general hospitals. Methods A Chinese version of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) Axis I Disor?ders was conducted by five mental health professionals on 876 essential hypertensive outpatients at cardiovascular divi?sions of tertiary general hospital. Data on the socio-demographic and clinical characteristics of these hypertensive pa?tients were also collected. Results The current prevalence of depressive disorders among essential hypertensive outpa?tients of tertiary hospitals was 16.6%(145/876). Risk factors for depressive disorders in hypertensive patients included fe?male gender (OR=2.817, 95%CI:1.161~6.885), being 65-year-old and older (OR=1.747, 95%CI:1.118~2.688), non-marital status (OR=2.023, 95%CI:1.203~3.398), gradeⅢhypertension (OR=1.776, 95%CI:1.226~2.333) and car?diovascular diseases (OR=2.018, 95%CI:1.427~2.587). Conclusion Essential hypertensive outpatients, who receive med?ical services at cardiovascular divisions of tertiary general hospital, have high prevalence of depressive disorders. Clini?cians should pay more attention to the mental health of outpatients with essential hypertension.

The functional magnetic resonance imaging (fMRI) study of auditory sensory gating in the siblings of schizophrenic / 中国神经精神疾病杂志

Objective To investigate auditory sensory gating potential in the siblings of schizophrenic, to discover the neuroimaging features of sensory gating associated with schizophrenia as intermediate phenotypes. Methods Twelve siblings of schizophrenia patients in the first episodic, and 12 healthy controls matched in gender, age, education under?went MRI scan when performing a auditory sensory gating fMRI task (repeated clicks and single click auditory stimuli). The measure of sensory gating was the contrast of repeated clicks minus single click. The analysis of result was imple?mented in SPM2. Results Compared with healthy controls, schizophrenia patients showed significant overactivation in the right inter cingulate gyrus (x=4,y=8,z=32) and left anterior cingulate gyrus (x=-8,y=4,z=28) during the fMRI senso?ry gating task. Conclusion Sensory gating is overactivated in the cingulate gyrus in siblings of schizophrenic. This pat?tern may be a potential endophenotype of schizophrenia.
