Abstract: A nanodelivery system based on globulin-1 S allele, a preparation method therefor and use thereof are provided. The preparation method includes the following steps of: dissolving globulin-1 S allele in a NaCl solution, and performing magnetical stirring until the globulin-1 S allele is completely dissolved to obtain a mixed solution; self-assembly: centrifuging the mixed solution, taking the supernatant to be dispersed into a dispersion solution for self-assembly to obtain a globulin-1 S allele dispersion; and adding hydrophobic plant polyphenol to the globulin-1 S allele dispersion, performing well mixing and centrifuging, and removing the supernatant to obtain the nanodelivery system based on the globulin-1 S allele.

Abstract: The present invention discloses Lactobacillus sakei for alleviating allergy and a preparation method thereof, and particularly Lactobacillus sakei for alleviating wheat-dependent, exercise-induced anaphylaxis (WDEIA). The Lactobacillus sakei is classified and named as Lactobacillus sakei. The Lactobacillus sakei has been preserved in China Center for Type Culture Collection since Apr. 12, 2003, with a preservation number of CCTCC DB 20082413. The Lactobacillus sakei can regulate the immune function of a human body to prevent/treat WDEIA by reducing the contents of specific IgE and histamine in serum of WDEIA patients.

Abstract: A method for establishing an epicutaneously sensitized food allergy animal model and belongs to the technical field of medical evaluation and detection. The method includes an allergen sensitization stage and an allergen challenge stage, wherein an MC903 ethanol solution containing OVA is smeared on the skin of experimental animals in the allergen sensitization stage, and the OVA dissolved in a buffer solution is used for an oral challenge in the allergen challenge stage.

Abstract: A switchable intelligent fitness handle is disclosed. A processor (11), a movement posture sensor (12) and a touch sensor (13) are built in the handle (7). The movement posture sensor (12) and the touch sensor (13) are connected to the processor (11). Each handheld fitness equipment has a corresponding sensor, and a pin connector (16, 17, 18, 19) that is matched with the bayonet (15) of the handle and provided with a signal line. Thus, the goal of accomplishing a set of exercises with a plurality of handheld fitness equipments by using one same set of handles can be achieved. An intelligent fitness set containing the fitness handle is further disclosed.
