Hippocampal pathology has been considered to underlie clinical, functional and cognitive impairments in schizophrenia. While longitudinal magnetic resonance imaging (MRI) studies have demonstrated progressive gray matter reduction of the hippocampus during the early phases of schizophrenia (SCZ), very little is known about whether functional connectivity(More)
Early onset schizophrenia (EOS) is often associated with poorer outcomes, including lack of school education, higher risk of mental disability and resistance to treatment. But the knowledge of the neurobiological mechanism of EOS is limited. Here, using proton magnetic resonance spectroscopy, we investigated the possible neurochemical abnormalities in(More)
The underlying mechanism of modified electroconvulsive therapy (MECT) treatment for drug-resistant and catatonic schizophrenia remains unclear. Here, we aim to investigate whether MECT exerts its antipsychotic effects through elevating N-acetylaspartate (NAA) concentration measured by proton magnetic resonance spectroscopy (H-MRS). Multiple-voxel H-MRS was(More)
OBJECTIVE To explore the potential effects of modified electroconvulsive therapy (MECT) in prefrontal lobe and thalamus in patients with schizophrenia by proton magnetic resonance spectroscopy ((1)H-MRS). METHODS From November 2010 to June 2011, a total of 31 schizophrenics fulfilling the third edition of the Chinese Classification of Mental Disorders(More)
OBJECTIVE To explore the characteristics of different subtypes of schizophrenics on prefrontal lobe and thalamus by proton magnetic resonance spectroscopy ((1)H-MRS) and its relationship. METHODS From August 2007 to April 2010 at our center, a total of 159 schizophrenics fulfilling the third edition criteria of Chinese Classification of Mental Disorders(More)
An overlay multicast is proposed to solve the scalability and deployment problems in IP Multicast. We propose a scheme, Topology-oriented Load- balance Hierarchical Independent Tree (TLHIT) to improve the performance of overlay multicast. Compared to traditional methods, the proposed TLHIT constructs not only node-disjoint but also path-disjoint multicast(More)
An overlay multicast is proposed to solve the scalability and deployment problems in IP Multicast. We propose a scheme, Topology-aware Load-balance Hierarchical Independent Tree (TLHIT), with topology-aware, load-balance and path diversity properties to improve the performance of overlay multicast. Compared to traditional methods, the proposed TLHIT(More)
