Gene expression profiling in drug addicted brain

Abstract

Drug addiction, a chronic brain disease caused by interaction of in vitro drug toxification and in vivo gene susceptibility, has been widely studied but its underlining mechanism is so far been elucidated. A major goal in this field is to identify drug-induced molecular changes and their effects on brain function. By the advance of high throughput technologies in genomics and transcriptomics, the whole gene expression profile in addicted brain could be obtained and proved to be a very powerful tool to unclose the molecular mechanism underlying the addiction biology context. Here, we summarized the progress of serial analysis of gene expression (SAGE) and microarray, as well as their application in drug addiction.

The Development of Clinical Document Standards for Semantic Interoperability in China

“…This dramatic reduction in the number of elements resulted from similar clinical procedures in most hospitals. Second, the framework of Diagnostics [ 16 ] knowledge and the approaches of the HL7 CCD, the IHE PCC and the HITSP for assembling templates and modules were considered together to propose the DGs' architecture. Third, the proposed DGs were used to construct 145 clinical record sheets as a pilot study to test their integrality.…”
