The invention provides low-molecular sea cucumber glycosaminoglycan. The constitutional units of the low-molecular sea cucumber glycosaminoglycan include glucuronyl groups, N-acetylaminogalactosyl groups, and fucosyl groups and sulfate groups or acetyl ester groups thereof. According to the invention, glucuronic acid and N-acetylgalactosamine are interactively connected through beta(1-3) and beta(1-4) glucosidic bonds to form a main chain of a disaccharide repetitive structural unit, and the fucosyl groups are connected to the main chain in a side chain form; and a molar ratio of the glucuronyl groups to the N-acetylaminogalactosyl groups to the fucosyl groups is 1: (0.8-1.2): (0.6-1.2). In the structure of the low-molecular sea cucumber glycosaminoglycan, 10%-30% of the positions 2 of theglucuronyl groups are modified by the sulfate groups, with the balance being hydroxyl groups; and 10%-30% of the positions 2 of the fucosyl groups are modified by the acetyl ester groups, with the balance being the hydroxyl or sulfate groups. The low-molecular sea cucumber glycosaminoglycan disclosed by the invention has the effects of resisting inflammation, vasculopathy, tumors or tumor metastasis and improving learning and memory abilities, and can be used for preparing related medicines or health care products.

The invention refers to a Se-rich cushaw health drink making method, the health drink rich in natural Se component, improving functionality of drink, able to effectively eliminate free group in human body, strengthening immune function of human body, and fully preserving nutrition constituent in the cushaw. It includes the operating steps: making natural Se-rich cushaw into juice, adding compound stabilizer, protein sugar and pure water in the juice to prepare the finished product.

A seaweed vinegar is prepared through washing seaweeds, dripdrying, grinding to become paste, regulating pH value, liquefying, saccharifying, fermenting in alcohol, fermenting in vinegar, filtering and sterilizing. Another preparing method is also disclosed. Its advantages are rich nutrients including fatty acids, mucopoly saccharide, amino acids, minerals, vitamines, and sodium alginate, sure health-care functions of lowering blood viscosity, preventing and treating tumor, regulating blood pressure, etc, and low cost.

The invention discloses an ophthalmic medicine slowly-releasing carrier with synergetic effect, which is characterized in that the medicine slowly-releasing carrier is bletilla striata gum, the main component of the bletilla striata gum is glucomannan which is polymerized by mannose and glucose at the ratio of 1 to 4; the average molecular weight is from 65000 to 150000, preferentially 100000. bletilla striata gum is accounted as glucomannan with a content being more than 85percent. Cross-linking agent which fulfills the effect of solidification is also added in the bletilla striata gum at theweight ratio of 100 to 0.01-20. The cross-linking agent is formaldehyde, glutaraldehyde, glycol diglycidyl ether, propanediol diglycidyl ether, or butanediol diglycidyl ether. Albumin, gelatin, or gum acacia are also added in the bletilla striata gum. The ophthalmic medicine slowly-releasing carrier of the invention not only can release the medicine slowly, but also has activity for clinically protecting the damaged tissue, preventing tumour, resisting oxidation, inhibiting neovascularization, etc, and has certain synergetic treatment effect on the medicine being carried with better curativeeffect.

The invention belongs to the technical field of functional food additives and nutritional health-care products, and particularly relates to the application of algal polysaccharide. The algal polysaccharide is used for preparing prebiotics in the functional food additives and the nutritional health-care products. The algal polysaccharide which is used as a raw material of the prebiotics is from large economic red algae, raw material sources are rich, the production cost is low, the preparation technology is simpler, and the algal polysaccharide has the efficacies of improving the immunity of a human body, preventing and treating tumors and the like, so that the algal polysaccharide which is used as the prebiotics has a quite obvious health-benefiting effect.

The present invention discloses the transformation of lactic acid bacteria with TIM3 human single-chain antibody (TIM3Fv) fusion gene, including the transformation of TIM3Fv gene or CTB-TIM3Fv fusion gene into lactic acid bacteria. The TIM3Fv gene or CTB-TIM3Fv fusion gene is inserted into lactic acid bacteria expression vector pLN and transformed The lactic acid bacteria are obtained, and the application of the transformed bacteria in preparing the oral live bacteria medicine with the effect of disease immunotherapy is also disclosed. In the present invention, the TIM3Fv and CTB-TIM3Fv fusion genes transformed into lactic acid bacteria can be prepared into viable bacterial preparations such as viable bacterial suspensions, dairy products, live bacterial powder, bacterial tablets or capsules, which can be used as immunotherapy live bacteria after oral administration and can proliferate in the human intestinal tract It is used in the prevention and treatment of tumors, viral infections or intracellular bacterial infections, primary and secondary immunocompromised diseases.
