The invention discloses a skin cell nucleus nutritional agent containing traditional Chinese medicine components and capable of improving ichthyosis and a preparation method, and relates to the technical field of preparation of skin cell nucleus nutritional agents. Comprising the following raw materials: modified vitamin A propionate, a traditional Chinese medicine extract, modified hydrogenated lecithin, squalane, beewax, stearyl alcohol, vaseline, glycerin, sodium hyaluronate, beta-glucan, propylene glycol, potassium cetyl phosphate, a preservative, allantoin, deionized water, triethanolamine and a lipid solvent. According to the invention, the modified tretinoin propionate is added, and the modified tretinoin propionate is subjected to double-grafting modification through glycyrrhetinic acid-hyaluronic acid oligosaccharide and is gently combined with a basal cell tretinoin receptor in a targeted manner, so that excessive proliferation of basal cells can be inhibited, and normal differentiation of keratinocytes can be promoted; wherein the glycyrrhetinic acid component can resist inflammation, relieve and reduce self-irritation, and the hyaluronic acid oligosaccharide can improve targeting and transdermal efficiency, avoid light / oxygen degradation and provide a core regulation effect for restoring the 28-day metabolic cycle of basal cells.

A fire-retardant topical formulation comprising glycerol and urea in a ratio of 1:1 to 1:30 is provided. The formulation may further comprise polyvinyl pyrrolidone and / or ethylhexylglycerin, and / or a barrier forming agent and / or a stabilising agent. The formulation may be a moisturiser, shampoo, conditioner, hair dye, sun cream, aftersun composition, emollient or medical composition. The formulation may be for use in treating a skin condition, such as eczema, dermatitis, psoriasis, elderly dry and itchy skin, ichthyosis, rash, or infection. The composition when transferred to a fabric suppresses the flammability of the fabric and is also capable of being removed from the fabric by washing. A preferred formulation comprises 1% phenoxyethanol, 10% urea, 10% sodium lactate (60% solution), 1% lactic acid, 1% glycerol, 3% ethylhexylglycerin, 2% polyacrylate crosspolymer-6, 0.5% polyvinylpyrrolidone and 71.5% water by weight. A fire-retardant topical formulation comprising 1% glycerol, 2% polyacrylate crosspolymer-6, 10% sodium lactate solution, 1% phenoxyethanol, 1% lactic acid, 3% ethylhexylglycerin and 0.5% polyvinylpyrrolidone by weight is also disclosed.

The invention discloses a construction method and application of a gene knockout mouse model based on ichthyosis virulence gene GLTP. The NCBI (National Center of Biotechnology Information) gene ID (Identity) of the GLTP gene is 51228. The Gltp gene knockout mouse model is constructed by the following method: assembling sgRNA of a targeted mouse Gltp gene and Cas9 protein in vitro to obtain a CRISPR (clustered regularly interspaced short palindromic repeats) / Cas9-sgRNA compound; performing micro-injection on the compound to fertilized eggs of mice, and transplanting the fertilized eggs to obtain positive F0-generation mice; after the positive F0-generation mice and wild mice are mated, heterozygotes are screened, the heterozygotes are subjected to selfing, and the F0-generation mice are obtained. The GLTP gene is clearly identified as a new pathogenic gene of ichthyosis for the first time, the constructed Gltp gene knockout mouse model can spontaneously generate ichthyosis-like skin lesion, human disease characteristics are simulated, and a more ideal tool is provided for researching ichthyosis disease pathogenesis and screening targeted drugs.

The invention relates to methods of treating ichthyosis in a subject with an inhibitor of the interleukin 36 (IL-36) pathway, and methods of selecting a subject for therapy with the IL-36 pathway inhibitor.

The application discloses a kit for constructing ABCA12 gene mutation speckled ichthyosis model pig nuclear transfer donor cells and application thereof. The application provides a kit comprising ABCA12-gRNA1 shown in SEQ ID NO: 16, ABCA12-gRNA4 shown in SEQ ID NO: 17 and NCN protein. The application also provides a method for preparing a recombinant pig cell: ABCA12-gRNA1, ABCA12-gRNA4 and NCN protein are co-transfected into a pig cell to obtain a recombinant pig cell. The recombinant pig cell is a recombinant pig cell with ABCA12 gene mutation. The kit is used for: preparing a recombinant pig cell; preparing a speckled ichthyosis model pig; preparing a speckled ichthyosis cell model or a speckled ichthyosis tissue model or a speckled ichthyosis organ model.
