Objective: The aim in this study was to synthesize a novel chitosan derivative, galactosylated chitosan (GC), and prepare norcantharidin-associated galactosylated chitosan nanoparticles (NCTD-GC-NPs) with GC as hepatocyte-targeting carriers and norcantharidin (NCTD) as model drug against primary liver carcinoma.

METHODS Norcantharidin-associated galactosylated chitosan nanoparticles were achieved by ionic cross-linkage process with galactosylated chitosan as carrier.

N-alkyl-lactosylated-O,N-carboxymethyl chitosan are prepared by carboxymethyl-chitosan with alkyldehyde and lactose.

Isolation and enrichment of fetal nucleated red blood cells by using N-acetylgalactosamine-specific lectin;

Objective To investigate the relationship between serum IgA1 molecular N- acetylgalactosamine abnormality and pathological manifestations of nephropathy among Mongolian ethnicity and Han group in Inner Mongolia region.
