The invention relates to an absorbable magnesium alloy staple having antibiosis and anti-inflammation functions, and a making method thereof. The staple is composed of a pure magnesium or magnesium alloy wire core with the surface containing a porous ceramic layer, an intermediate functional layer loaded with anti-inflammation medicines and copper ions with gelatin as a carrier, and a degradable high-molecular external surface layer. The copper ions and the anti-inflammation medicines are effectively loaded on the surface of the wire with gelatin as the carrier by adopting an electrophoresis-electrodeposition process, and the external surface layer of the staple is a degradable high-molecular layer having a protection effect. The staple can slowly release the copper ions having a sterilizing effect and the anti-inflammation medicines having an anti-inflammation effect in the use process. Additionally, the synergistic effect between the intermediate functional layer with the gelatin as the carrier and the external degradable high-molecular layer realizes the effective control of the medicine release rate and the staple degradation speed. The staple can be widely applied to the stitching or inosculation of the intestine, the stomach and other human body different positions, and has a wide application prospect.

The invention discloses a preparation method and an application of UTY antibody nano-particles for fast separation of X / Y sperms of cattle and sheep. The preparation method comprises steps as follows: a monoclonal antibody resisting a Y sperm UTY antigen is prepared from Y sperm UTY antigen recombinant protein; the monoclonal antibody is subjected to enzyme digestion by pepsase, and Fab' fragments resisting an anti-UTY antigen are obtained through separation; calcium phosphate nano-particles containing the Fab' fragments are prepared. The prepared UTY antibody nano-particles have the capacity of performing antigen-antibody reaction on the surfaces of the Y sperms and inside the Y sperms, thereby leading to Y sperm agglutination, the separation efficiency of X / Y sperms reaches 80%-95%, and the UTY antibody nano-particles have the characteristics of simple, fast and cheap X / Y sperm separation, high efficiency and the like and has extremely small damage.

The invention discloses a medical inflation and curing bone-forming agent for strengthening a vertebral body, which is prepared by mixing the following components in percentage by weight: 10 to 20 percent of expanding agent, 30 to 40 percent of curing agent, 30 to 40 percent of bone-forming agent and the balance of water, wherein the total weight percentage of the expanding agent, the curing agent, the bone-forming agent and the distilled water is 100 percent. The whole strengthening degree of the vertebral body can be obviously enhanced under an osteoporosis condition; the stability of the vertebral body is improved; the leakage of a filled material is reduced; the distribution uniformity of the filled material in the vertebral body is improved; new bones are promoted to be formed in the vertebral body at the same time; an osteoporosis state is improved; and the clinical treatment effect is effectively improved. The medical inflation and curing bone-forming agent is a vertebral body strengthening material, which is obvious in expansion effect and good in mechanical property and bone-forming effect.

The invention belongs to the field of cosmetics and particularly relates to egg white shower gel. The egg white shower gel comprises, by weight percentage, 5-10% of egg white hydrolysate, 2-5% of rose extract, 2.5-5% of glycerol, 2.5-5% of sorbitol, 5-10% of sodium laureth sulfate, 1-6% of alpha-olefin sulfonate, 1-6% of lauramide propyl betaine, 2-4% of sodium lauroyl sarcosine, 1-4% of coconut oil monoethanol amide, 0.2-1% of citric acid, 1-5% of sodium chloride, 0.05-0.15% of DMDM hydantoin, 0.05-0.15% of ethylene diamine tetraacetic acid disodium, 0.1-1% of essence and 55-70% of deionized water. The egg white shower gel has the advantages that the egg white shower gel uses the egg white hydrolysate as the active constituent and is rich in bubble and non-irritant, the skin is smooth after bathing, and a good skin tendering effect is achieved.

The invention relates to an absorbable orthopedic apparatus material having antibiosis and bone growth promotion functions, and a preparation method thereof. The orthopedic apparatus material is obtained by compounding medical pure magnesium or magnesium alloy with an absorbable high-molecular polymer, the surface of the pure magnesium or magnesium alloy has a porous ceramic layer, the surface of the porous ceramic layer is a functional load layer loaded with bone morphogenetic proteins and copper ions with B-type gelatin as a carrier by adopting an electrophoresis-electrodeposition process, the volume fraction of the pure magnesium or magnesium alloy is 1-99%, the micropore aperture and the thickness of the porous ceramic layer on the surface of the pure magnesium or magnesium alloy are 1-100[mu]m and 1-100[mu]m respectively, and the surface of the porous ceramic layer is the functional load layer loaded with bone morphogenetic proteins and copper ions with B-type gelatin as the carrier by adopting the electrophoresis-electrodeposition process. An orthopedic apparatus can slowly release copper ions having a sterilizing effect and bone morphogenetic proteins having a bone growth promotion effect in the use process, can be applied to restore and fix various bone injuries, and has a wide application prospect.

The invention discloses a preparation method for a composite hollow material. The preparation method comprises the following steps: growing a metal organic framework thin film by use of a liquid phaseepitaxial growth method, and then performing calcination. The method has the advantages of high synthesis speed, high preparation efficiency, controllable thin film thickness, environmental friendliness, low cost, simplicity for operation and the like, and a convenient method is provided for large-scale preparation. An obtained carbon-based composite material is of a hollow structure and relatively high in electrical conductivity, and has broad application prospect for super capacitors and other electrochemical fields, and electrons can be diffused and transported conveniently.

The invention relates to a preparation method of artificial skin, in particular to a preparation method of artificial skin with hair follicles and the skin made by the method, belonging to biomedical field. The preparation method comprises the following steps: (1) preparing the epithelial cells of the hair follicle; (2) culturing the dermal papilla cells; (3) culturing the artificial skin with hair follicles.
