The invention discloses a two-factor fusion protein of Flt3L and IL-7 (interleukin-7) and application of the two-factor fusion protein. Relates to the technical field of biology. According to the fusion protein provided by the invention, two heavy-like chains are connected through a disulfide bond to form a homodimer, and the fusion protein realizes double functions through a single molecule: Flt3L targets Flt3 to drive bone marrow precursor cells to be differentiated into dendritic cells, so that a DC library is expanded; maintaining development, survival and steady state of T cells and B cells through IL-7 is crucial to long-term survival of initial and memory T cells. The two have functional complementarity and are used for respectively promoting differentiation and maturation of DC precursor cells, and the DC cells further activate T lymphocytes; meanwhile, T lymphocytes are supplemented, so that systematic immunoregulation is realized, the fusion protein has disease universality, and a new technical support is provided for immune anti-aging and prevention and treatment of tumor and microbial infection.

This invention belongs to the field of cosmetics, specifically relating to an anti-chapped skin composition and its preparation method. The anti-chapped skin composition, by mass ratio, comprises the following components: 5.0–20.0% polyol, 0.1–1.0% allantoin, 2.0–10.0% petrolatum, 2.0–10.0% mineral oil, 0.1–3.0% tea seed oil, 0.1–2.0% tocopheryl acetate, 2.0–5.0% polyglycerol-3-methylglucose distearate, 1.0–8.0% fatty alcohol, 0.1–0.3% thickener, 0.1–0.3% potassium cetyl phosphate, and the balance being deionized water. The anti-chapped skin composition prepared by this invention effectively protects the skin from external factors, repairs damaged skin, and is gentle and non-irritating to the skin. It moisturizes the stratum corneum, locks in skin moisture for a long time, and prevents skin chapping.
