The invention especially relates to application of tamoxifen and a method for constructing a cleft palate animal model, belonging to the field of genetic engineering technology. Research results of the invention show that a female mouse (Tgfbr1<f / f>K14Cre+) is mated with a male mouse (Tgfbr1<f / f>K14Cre-), or a female mouse (Tgfbr1<f / f>K14Cre-) is mated with a male mouse (Tgfbr1<f / f>K14Cre+), and Tgfbr1 gene knockdown can be performed on a fetal mouse thereof under the induction of tamoxifen; so the cleft palate animal model is constructed. In the mouse constructed by using the method of the invention, Tgfbr1 genes in palatal epithelial cells are knocked out, and interference of other factors in the cleft palate model is reduced.

The paste comprises the following substances: a bletilla striata extraction liquid, a red date extraction liquid, a flowers carthami extraction liquid, a banana peel extraction liquid, an apple peel extraction liquid, a garlic extraction liquid, a radix polygonati officinalis extraction liquid, orange peel juice, egg oil, beewax, lithospermum soaked oil, sesame oil, a natural emulsifier GOC, an all-round emulsifier, glycerin, sodium carboxymethylcellulose, sodium alginate, essence, ethylparaben, distilled water, 1,2-propylene glycol and the like. Compared with the prior art, the paste has the advantages of being small in side effect, good in compliance, good in moisture retention and the like. As the extraction liquids, comprising a lot of polysaccharides, lipid, vitamins and the like, of natural medicines are adopted, the paste also plays roles of improving local blood circulation, nourishing and moisturizing skin, preventing bacteria and oxidization and delaying skin ageing while treating skin chap.

The invention relates to urea and vitamin E cream for treating hand and foot rahagades and rahagades caused by keratotic tinea hand or pedis. The cream contains urea, vitamin E, catechinic acid and polyoxyethylene-7-stearate. The fine cream with small and uniform particle size and good coating property can be prepared through low-speed stirring. The cream has higher high temperature stability, and oil-water layering does not occur easily. The cream is suitable for industrial production, production processes are simplified, energy is saved, and stability is higher.

The invention relates to application of an allograft acellular dermal matrix in oral diseases, in particular to application of the allograft acellular dermal matrix in the repairing of cleft lip and / or alveolar cleft, cleft palate and oral mucous membrane defect, the repairing of periodontal defect and gingival recession, the repairing of nasal mucosa, tooth implantation, the repairing of furcation involvement and the prevention of complications such as dry socket after impacted tooth extraction, and belongs to the technical field of biological medical material tissue engineering. The allograft acellular dermal matrix is a product improved by a process, the mechanical performance of the product is suitable for surgery, and the sewing strength of the product is 16-18N; the allograft acellular dermal matrix is free of immunological rejection, capable of fast inducing tissue regeneration, soft in texture after implantation, free of contour feeling and good in in-vivo compatibility and hasa stable stent and template effect.

The invention discloses a cleft palate speech initial and final automatic segmentation method and a cleft palate speech initial and final automatic segmentation system, which relate to the field of speech signal processing technologies, especially a cleft palate speech initial and final automatic segmentation technology. The invention aims to provide an initial and final automatic segmentation algorithm for cleft palate speech to solve the technical problem that an initial and final automatic segmentation algorithm for the cleft palate speech does not exist in the prior art. The cleft palate speech initial and final automatic segmentation method is characterized by carrying out the processing steps on a syllable including an initial: a quasi voiced initial and a quasi voiceless initial distinguish step, which is used for distinguishing whether the syllable is a syllable comprising a quasi voiced initial or one comprising a quasi voiceless initial; an initial and final segmentation step for the syllable comprising the quasi voiced initial; and an initial and final segmentation step for the syllable comprising the quasi voiceless initial.

The invention relates to a method for conditional knockout of Lox13 gene of a mouse and an application. The method comprises the steps that loxP loca of a Cre recombinase targeting sequence are added to the two ends of a key exon of an Lox13 gene; a conditional gene knockout carrier is constructed, and transfected with an embryonic stem cell (ESC); microinjection is conducted for making a floxed mouse capable of being used for conditional gene knockout; the floxed mouse is mated with a Cre mouse with corresponding tissue specificity; and the mouse of which an Lox13 gene can be knocked out at a specific tissue is obtained. The mouse obtained by the method serves as a model mouse for morbidity research on a cleft palate disease, so that the functions of the Lox13 gene in the tissue and the effects of the Lox13 gene in an embryonic development regulation mechanism can be illustrated in details. In addition, the mouse can serve as an animal model for researching the functions of the Lox13 gene, and has important application values.

The invention discloses a three-dimensional culture method for palatal organs in vitro. The whole tissue from the inferior orbital edge to the corner of the mouth is taken from the embryonic palate in the early stage of development or in the developmental stage, embedded in a hydrogel support, and culture solution is added for three-dimensional culture. It can provide a three-dimensional growth environment similar to the body, avoid the use of expensive materials and processes, and has the advantages of simple operation and low cost. In addition, the biological characteristics of the palatal plate tissue can be adjusted by changing the composition of the hydrogel scaffold, which is suitable for different stages of embryonic development The tissue culture of normal and abnormal palate plate can be used for the study of the formation mechanism of cleft palate and the screening of drugs that promote the formation of palate plate.
