This application relates to a video coding method and apparatus, a computer device, and a storage medium. The method includes: obtaining a current coding unit; obtaining target pixel gradient data through calculation according to a pixel value of a pixel in the current coding unit, the target pixel gradient data being obtained according to a difference between the pixel value of the pixel and a reference pixel value; determining a target division decision result corresponding to the current coding unit according to the target pixel gradient data; and performing video coding on the current coding unit according to the target division decision result.

Video coding method and apparatus, computer device, and storage medium

Disclosed is a depolymerized glycosaminoglycan from(dTHG), weight average molecular weight of which is about 8000&#x2dc;20000 Da, and monosaccharide components of which are acetylgalactosamine (GalNAc), glucuronic acid (GlcUA), fucose (Fuc) or their sulfates (expressed as &#x2014;OSO), in which molar ratio of GalNAc:GlcUA:Fuc:&#x2014;OSOis about 1:(1&#xb1;0.3):(1&#xb1;0.3):(3.5&#xb1;0.5). Said dTHG is a potent endogenous inhibitor of factor X, which has good anticoagulant and antithrombotic activity, and can be used for the prevention and/or treatment of thrombotic diseases. Also provided is a method for preparing said dTHG, which comprises steps of 1) extracting and obtaining fucosylated glycosaminoglycan (THG) from the body wall of; 2) depolymerizing THG to obtain dTHG by method of peroxide depolymerization or method of peroxide depolymerization catalyzed by catalyst of the fourth period transition metal ions; 3) removing impurities with lower and/or higher molecular weight in dTHG.
