The invention discloses an improved culture medium for neonatal pig islet cells and a use method of the same. An apoptosis inhibitor Z-VAD-FMK, a human basic fibroblast growth factor hFGF-beta, a vascular endothelial growth factor VEGF, an insulin-like growth factor R3-IGF-1, a human epidermal growth factor hEGF, a hepatocyte growth factor hHGF, pig serum, sodium selenite, insulin, transferrin, ethanol amine, 1-methyl 3-isobutyl xanthine, nicotine, cortisol, penicillin and streptomycin are added in HAM'S F10 culture medium. According to the culture medium, apoptosis can be reduced and recovery rate can be increased; the cultured cells have a sensitive glucose stimulation response and more mature functions compared with generally-cultured islet cells; the insulin secretion amount of the islet cells with the same quantity is increased; the viability of islet beta-cells is improved; the breakages of islet cell clusters are reduced, and the envelops of the cell clusters are complete, so that the cell clusters are more suitable for being transplanted.

The invention relates to the technical field of skin care products, and particularly relates to anti-freeze hand cream and a preparation method of same. The anti-freeze hand cream is prepared from the raw materials including, by weight, 10-20 parts of extract of prunus mume, 10-15 parts of allantoin, 0.01-0.5 parts of a stem cell secretion factor, 30-40 parts of an emulsifier, 10-20 parts of squalane and 15-25 parts of water. The anti-freeze hand cream can effectively protect hands and comprehensively care hands, can improve the capability of synthesizing collagen proteins by fibroblasts in skin and can repair cells, improve cell metabolism and activate senile cells. The anti-freeze hand cream also has a delicate fragrance and can refresh mood of people, and is comfortable to use.
