The application discloses a kind of sea fish mycobacterium infection mouse model based on T cell immune state difference and its construction method and application.The method under unified infection condition (bacterial amount 1×10 4 CFU, temperature 25 DEG C, time 4 weeks), respectively, constructs the infection model of congenital T cell immune deficiency nude mouse and the thymus pentapeptide processing mouse model of acquired T cell immune regulation, by comparing and analyzing the infection phenotype and pathological changes under different immune states, for the mechanism of T cell immunity in non-tuberculous mycobacterium infection, screening immune regulation treatment drug provides standardized experimental model.

The invention discloses a preserving fluid for an umbilical cord mesenchymal stem cell preparation. The preserving fluid comprises 0.9% sodium chloride injection, human serum albumin and thymopentin for injection. The preserving fluid can stably preserve stem cells for 72 hours at the room temperature of 15-30 DEG C, and the cell viability is maintained to be 80% or above; meanwhile, the preserving fluid is simple in component, does not contain complex additives such as a pH buffering agent and an antioxidant, and is simple and convenient in preparation process and easy in cost control.

The invention relates to the technical field of molecular biology, in particular to a polypeptide with detoxification, anti-inflammatory and antioxidant functions and application thereof. The polypeptide comprises one of the following amino acid sequences: i) an amino acid sequence as shown in SEQ ID NO.1; and ii) an amino acid sequence which is obtained by substitution, insertion or deletion of one or more amino acids on the amino acid sequence as shown in SEQ ID NO.1 and has the same functional protein. The novel DTP hybrid peptide is obtained on the basis of a defensive peptide DEFB126 core functional region and thymopentin TP5 through protein engineering computer design, heterozygosis, optimization and in-vivo and in-vitro re-screening, and the DTP hybrid peptide has excellent anti-inflammatory and antioxidant activity, excellent anti-apoptosis and anti-liver injury activity, high stability and low cytotoxicity. The method can be widely applied to the fields of medicine, health care, food, veterinary medicine, feed and the like, and has extremely high application potential and value.
