After alkaine hydrolysis, the body wall of Slicliopus varicyatus was fractionally pre-cipitatecd with alcohol, then oxidatively decoloured and purified with KAc, the elcctrophorelically pure polysaccharides SVI and SVIIwere obtained. The results of ultracentrifugal analysis showed that the sedimentation coefficients were S20w 3. 09 for SVI and S20w 2. 12 for SVII. The metachromatic reaction with reddish black I showed the metachromatic peaks of SVI and SVII were shifted to 514nm and 507nm, respectively. The molecule of SVI is composed of aminogalactose, glucuronic acid, fucose and sulfate (1:1. 21:1. 29:4. 62) and that of SVII is composed of fucose and sulfate (1.0. 99). And our results of Stichopus japonicus acidic mucopolysaccharide ultracentrifugation therefore suggests that the sedimentation coefficients is S20w 2. 12. The metachromatic reaction with reddish black I showed the metachromatic peak is 515nm. The molecule of Sjamp is also composed of aminogalactose, glucuronic acid, fucose and sulfate ( 1:1. 1:1. 20:4. 87)

Gastrointestinal stromal tumors (GISTs) are relatively common mesenchymal tumors of the digestive tract characterized by c-kit mutations and the stomach is the commonly involved site.Clinical and pathological diagnosis of GISTs can be achieved by B sonography,computed tomography and immunohistochemical detection of marker CD117.Surgical resection of GISTs has been the most effective therapy.Target therapy with tyrosine kinase inhibitors may reduce the development of recurrence or progression of GISTs.The optimized method of diagnosis and treatment of huge GISTs is still controversial.In this paper,the diagnosis and treatment for huge GIST combined with large right inguinal hernia were discussed.
