    摘要: The present invention provides an alginate oligosaccharide or a pharmaceutically acceptable salt thereof in preparation of a drug for treatment of acute kidney injury, wherein the alginate oligosaccharide is an alginate disaccharide, an alginate trisaccharide, or an alginate tetrasaccharide. Studies have found that the alginate disaccharide, the alginate trisaccharide, and the alginate tetrasaccharide all show significant protective effects on animal models of acute kidney injury induced by ischemia-reperfusion (I/R), endotoxin phosphorus lipopolysaccharides (LPS) and anti-tumor drug cisplatin. After the treatment of acute kidney injury animals by the alginate oligosaccharide of the present invention, the level of serum creatinine decreases significantly, the urine concentration ability of kidneys recovers significantly, the level of renal tubular injury markers (KIM-1 and NGAL) is significantly reduced, the protein expression of inflammatory factors is significantly reduced, the pathological changes of the kidneys are significantly ameliorated, and the therapeutic effect is enhanced with the increase of dose. Therefore, the alginate oligosaccharide of the present invention has a strong effect in the treatment of acute kidney injury.
