The present invention relates to a method for reducing lipid binding of brazzein and / or to method for improving digestibility of brazzein in a subject's digestive track as well as to a modified brazzein polypeptide and uses of it and to a nucleic acid encoding the same.

The application provides a microorganism marker group, a tumor prognosis prediction model establishment method and application thereof, and relates to the technical field of biomedicine. The microorganism marker group is related to a preset total survival time. Based on the microorganism marker group obtained from tumor tissues and paracancer normal tissues, the prognosis prediction accuracy and sensitivity of a digestive tract tumor can be effectively improved.

This invention relates to the field of medical device technology, and more particularly to an acid and alkali resistant medical electro-adhesive surface. The invention provides an acid and alkali resistant medical electro-adhesive surface comprising a positive backbone ionogel and a negative backbone ionogel; the raw materials for preparing the positive backbone ionogel include polyvinyl alcohol, gelatin, chitosan and its derivatives, and conductive metal ion salts; the polyvinyl alcohol and / or chitosan and its derivatives include quaternary ammonium groups; the raw materials for preparing the negative backbone ionogel include sodium alginate and calcium chloride. The acid and alkali resistant medical electro-adhesive surface possesses characteristics of low-voltage drive, molecular-level adhesion, and adaptability to various tissues in the digestive tract.
