[Clinical efficacy of lower dose rituximab for chronic refractory immune thrombocytopenic purpura].

Objective: To investigate the efficacy and safety as well as the effects of lower dose of rituximab on B-lymphocytes, serum immunoglobulin, and platelet glycoprotein-specific antibodies in patients with chronic refractory immune thrombocytopenic purpura (ITP).

Methods: Twenty chronic refractory ITP patients, median age 47 (20 to 60) years old, received intravenous rituximab at the dose of 100mg once weekly for 4 consecutive weeks. Laboratory studies included complete blood cell count, regular monitoring of liver and kidney functions, blood coagulation and serum concentrations of IgG, IgM and IgA.

The role of Kupffer cells in rat liver regeneration revealed by cell-specific microarray analysis.

Liver regeneration after partial hepatectomy is a process with various types of cells involved. The role of Kupffer cells (KCs) in liver regeneration is still controversial. In this study we isolated KCs from regenerating liver and conducted cell-specific microarray analysis.

The number of the genes in a functional category matters during rat liver regeneration after partial hepatectomy.

Rat liver regeneration after partial hepatectomy (PH) is a good model to study the regulation of cell proliferation. We isolated hepatocytes from regenerating liver at different time points after PH and used microarray Rat Genome 230 2.0 chip to analyze the functional profiles of all up- or down-regulated genes manually and with automatic gene ontological tools.

Analysis of time-course gene expression profiles of sinusoidal endothelial cells during liver regeneration in rats.

Liver regeneration (LR) after partial hepatectomy (PH) requires the coordinate contribution of different cell types. Liver sinusoidal endothelial cells (LSECs), representing the largest population of nonparenchymal cells, are proven to be crucial in LR. However, the details about their implications in regeneration are not still clear.

Expression patterns and action analysis of genes associated with physiological responses during rat liver regeneration: cellular immune response.

Aim: To study the cellular immune response during rat liver regeneration (LR) at a transcriptional level.

Methods: Genes associated with the cellular immune response were obtained by collecting the data from databases and retrieving articles. Gene expression changes during LR were detected by rat genome 230 2.
