Abnormal activations of the ventral medial prefrontal cortex （vMPFC） during emotional tasks have been demonstrated in schizophrenia, suggesting its important role in emotion processing in patients. We used the resting-state functional connectivity approach, setting a functionally relevant region, the vMPFC, as a seed region to examine the intrinsic functional interactions and communication between the vMPFC and other brain regions in schizophrenic patients. We found hypo-connectivity between the vMPFC and the medial frontal cortex, right middle temporal lobe （MTL）, right hippocampus, parahippocampal cortex （PHC） and amygdala. Further, there was a decreased strength of the negative connectivity （or anticorrelation） between the vMPFC and the bilateral dorsal lateral prefrontal cortex （DLPFC） and pre-supplementary motor areas. Among these connectivity alterations, reduced vMPFC-DLPFC connectivity was positively correlated with positive symptoms on the Positive and Negative Syndrome Scale, while vMPFC-right MTL/PHC/amygdala functional connectivity was positively correlated with the performance of emotional regulation in patients. These findings imply that communication and coordination throughout the brain networks are disrupted in schizophrenia. The emotional correlates of vMPFC connectivity suggest a role of the hypo-connectivity between these regions in the neuropathology of abnormal social cognition in chronic schizophrenia.展开更多

In this article, we compared patients’ illness perception (IP), treatment adherence and coping mechanisms of patients undergoing percutaneous transluminal coronary angioplasty (PTCA). Methods: In this descriptive, prospective observational study IP, treatment adherence and coping of 140 patients were evaluated pre-PTCA, at the time of hospital discharge and 1 to 3 months post-PTCA by Illness Perception Questionnaire, Morisky Treatment Adherence and Carver’s brief COPE questionnaires. Results: 1 - 3 months post-PTCA, all dimensions of IP changed significantly except personal and treatment control. Adherence scores decreased simultaneously. With respect to coping mechanisms, all increased except behavioral disengagement, emotional support, instrumental support and religion which decreased significantly post-PTCA. Conclusions: In Overall, an improved IP and increased use of controllable causal attributions led to an increase in medication adherence and adaptive coping strategies. Post-treatment health behaviors are predictable by assessing patients’ illness-related beliefs beforehand.展开更多
