[Gfi-1 expression in leukemia patients and inhibitory effects of lentiviral vector mediated silence of Gfi-1 gene on proliferation in K562 cells].

This study was aimed to quantitatively detect the expression levels of gfi-1 gene in leukemia patients, and to investigate the effect of gfi-1 gene silenced by short hairpin RNA (shRNA) on proliferation of leukemia cell line K562. Quantitative real-time PCR and Western blot were used to detect the mRNA and protein expression levels of GFI-1 in newly diagnosed patients with leukemia. One pair of oligonucleotide sequences targeted at human gfi-1 mRNA were designed and synthesized.

Nephrogenic systemic fibrosis in advanced chronic kidney disease: a single hospital's experience in Taiwan.

Nephrogenic systemic fibrosis (NSF) or nephrogenic fibrosing dermopathy (NFD) clinically resembles scleromyxedema which develops in the setting of advanced chronic kidney diseases. Limited data exist about its epidemiology in Asian countries. A total of 153 magnetic resonance imaging (MRI) examinations, including 81 contrast-enhancement, were identified in 127 patients with advanced chronic kidney disease at stage five undergoing MRI or angiography examination between January 2005 and July 2007, in our hospital.

Synthesis of arbutin by two-step reaction from glucose.

Arbutin was synthesized from glucose by two-step reaction below: (a) 2,3,4,6-tetra-O-acetyl-alpha-D-glucosyl chloride or bromide was prepared by glucose and acetyl halide (chloride or bromide). (b) 2,3,4,6-tetra-O-acetyl-alpha-D-glucosyl halide (Cl, Br) reacted with hydroquinone, methanol as solvent at pH=9.5-10.
