Abstract: The present invention provides a solid mask and a preparation method thereof. The solid mask includes a hydrophobic substrate layer and a nanofiber layer, the nanofiber layer has a three-dimensional structure and is electro-spun onto the hydrophobic substrate layer through uniaxial electrostatic spinning technology, and the nanofiber layer is prepared by the following food-grade raw materials in parts by mass: 10 to 30 parts of gelatin, 1 to 30 parts of soya bean lecithin and 0.1 to 10 parts of a functional substance. The present invention provides a solid mask, using gelatin and soya bean lecithin as the framework. The nanofiber layer is a three-dimensional laminate made of fibers having a diameter of a few hundred nanometers. The nanofiber layer has a membrane structure similar to the extracellular matrix. The raw materials of the solid mask are all food-grade raw materials or natural extracts.

Abstract: The present invention relates to the field of food or health care product, in particular a polysaccharide composition and use thereof. In the present invention, lentinan, pachymaran and tremellan are compounded. The resultant composition can significantly improve the survival rate and quality of life of mice infected by influenza virus, improve the pulmonary inflammatory lesion degree in mice infected by influenza virus, significantly improve levels of specific antibodies in serum of mice infected by influenza virus, significantly decrease the virus content in the lung of mice infected by influenza virus, as well as improve levels of cytokines IL-2 and IL-5 in the lung. In comparison with existing vaccines or single polysaccharides, the polysaccharide composition as provided in the present invention has more significant protective effects on mice infected by influenza virus.
