OBJECTIVE This study used resting-state functional MRI (fMRI) to evaluate regional and network alterations in patients with Parkinson's disease (PD) with and without depression. METHOD We recruited 29 patients with PD with depression (PD-Dep), 30 patients with PD without depression (PD-NDep), and 30 normal controls. All participants underwent(More)
BACKGROUND Neurodegeneration with brain iron accumulation (NBIA) defines a group of genetic disorders characterized by brain iron deposition and associated with neuronal death. The known causes of NBIA include pantothenate kinase-associated neurodegeneration (PKAN), neuroferritinopathy, infantile neuroaxonal dystrophy (INAD), and aceruloplasminemia. (More)
The stimulating methods of prior studies on somatosensory evoked potentials (SEPs) elicited by acupoint stimulus had involved surface electrodes, while the clinical practice of acupuncture is mostly performed by inserting the acupuncture needle inside the body. Clinical observations show that there are often some special sensations when LI-4 is needled. To(More)
Ubiquitinated-protein aggregates are implicated in cerebral ischemia/reperfusion injury. The very presence of these ubiquitinated-protein aggregates is abnormal and seems to be disease-related. However, it is not clear what leads to aggregate formation and whether the aggregations represent a reaction to aggregate-mediated neurodegeneration. To study the(More)
PURPOSE To identify consistent results of voxel-based morphometry (VBM) studies in unilateral refractory temporal lobe epilepsy (TLE). METHODS Whole-brain VBM studies comparing refractory TLE patients with healthy controls (HC) were systematically searched in PubMed, ISI Web of Science, Embase, and Medline databases from January 1990 to May 2011.(More)
Oxidative stress is involved in the pathogenesis of multiple system atrophy (MSA). Uric acid has an antioxidative effect. Our aim is to clarify the correlations between serum uric acid and MSA in Chinese population. A total of 234 patients with probable MSA and 240 age- and gender- matched healthy controls were included in the study. The serum uric acid(More)
OBJECTIVE Our aim is to use the high field MR scanner (3T) to verify whether diffusion tensor imaging (DTI) could help in locating the epileptogenic zone in patients with MRI-negative refractory partial epilepsy. METHOD Fifteen patients with refractory partial epilepsy who had normal conventional MRI, and 40 healthy volunteers were recruited for the(More)
BACKGROUND Many voxel-based morphometry studies in Alzheimer's disease (AD) and mild cognitive impairment (MCI) yielded not entirely consistent results. We conducted meta-analyses of gray matter anomalies to identify robust neuroanatomical changes between them. METHODS A systematic review of voxel-based morphometry studies of patients with AD and MCI(More)
Aceruloplasminemia is an autosomal recessive disorder of iron metabolism resulting from mutations of the ceruloplasmin gene. To better define the neurological phenotype of aceruloplasminemia we reviewed reports of published cases and sought details of unpublished ones. We identified 32 published reports and 1 unpublished case. The age at diagnosis ranged(More)
To study the number cognition process, we recorded event-related potentials (ERPs) in 14 subjects when they were indicating whether a number pair was the same or not. The two numbers given in sequence were either the same (condition 1) or different (condition 2). After 270 ms following the onset of the second stimulus in condition 2, a negative component(More)
