Methods： With the BRB-Array Tools software package, original data collection and bioinformatic analysis of gene arrays were conducted in 6 CSG patients of PDS （CSG-PDS）, 6 CSG patients of non-PDS （CSG-nPDS）, and 6 healthy volunteers （Normal）. Results： Compared with non-PDS, the gene expressions in PDS with regards to protein synthesis, energy metabolism, immune reaction and ionic transport tended to be down-regulated, while those concerning secretion, cytoskeleton and ubiquitinization were up-regulated dominantly. Conclusions： The two kinds of samples, CSG-PDS/Normal and CSG-PDS/CSG-nPDS, have their respective gene expression profiles with different characteristics. Gene expression profile has certain referential significance in syndrome classification.展开更多
