Substantial individual differences characterize the changes induced by total sleep deprivation on cognitive functions. Despite some progress having been achieved, the mechanisms of individual differences in response to total sleep deprivation have not been clearly elucidated. Cerebral metabolism in the resting state is among the key physiological processes(More)
Several functional imaging studies have investigated the regional effects of sleep deprivation (SD) on impaired brain function; however, potential changes in the functional interactions between the cerebral hemispheres after SD are not well understood. In this study, we used a recently validated approach, voxel-mirrored homotopic connectivity (VMHC), to(More)
BACKGROUND Cerebral glucose metabolism changes are always observed in patients suffering from malignant tumors. This preliminary study aimed to investigate the brain glucose metabolism changes in patients with lung cancer of different histological types. METHODS One hundred and twenty patients with primary untreated lung cancer, who visited People's(More)
The aim of this study was to explore the functions of cerebral blood perfusion and glucose metabolism in the prefrontal lobe of patients with major depression disorder (MDD), and to analyze the correlations between these functional changes and depressive symptoms. 3D-arterial spin labeling (ASL) and 18F-fluorodeoxyglucose (FDG) positron emission(More)
Surgical treatment of adult Hirschsprung's disease is still controversial, although different kinds of procedure have been tried with varying success. With the experience of double stapling technique in a variety of colorectal diseases, we used this procedure in 2 patients with this disease. Both of them were diagnosed by barium enema, anorectal manometry(More)
OBJECTIVE To explore the cerebral blood flow (CBF) by three-dimensional arterial spin labeling (3D-ASL) and the standardized uptake value (SUV) of 18F-fluorodeoxyglucose (18F-FDG) in the prefrontal lobe of patients with major depression disorder (MDD), and analyze their correlations with patients' depressive symptoms. METHODS 3D-ASL and 18F-FDG positron(More)
