The invention belongs to the field of massage components, and particularly relates to a should and neck massage device. The should and neck massage device comprises a neck massage component and a shoulder massage component; the neck massage component comprises an arc heart-shaped neck pillow and a first massage machine, the neck pillow is used for coating and wearing the whole set of the first massage machine; the shoulder massage component comprises two shoulder pillows symmetrically arranged at the lower parts of the left side and the right side of the neck pillow and a second massage component; the shoulder pillow comprises an upper curved surface and a lower curved surface, a neck pillow clamping slot is internally sunken in the upper curved surface, the lower surface of the neck pillow is clamped in the neck pillow clamping slot in a dismounting manner; the lower curved surface comprises a first peak and a second peak, the first peak and the second peak are parallel, a shoulder installation part is formed between the first peak and the second peak, the shoulder pillow is worn on the shoulder of a wearer through the shoulder installation part, the opposite surfaces of the firstpeak and the second peak are elastic breathable surfaces; and the should and neck massage device acts on the rear cervical vertebra, the muscle groups around the rear cervical vertebra, the double shoulders and the muscle groups of the double shoulders at the same time, and can massage the rear cervical vertebra and the double shoulders in a targeted way.

The invention provides an aluminum adjuvant used as a vaccine vector. The adjuvant is characterized in that a PEG derivative bio-material and aluminum are compounded to form nano-particles, so that the property of strong Th2 body fluid immunologic adjuvant of aluminum salt is maintained, and the adjuvant can be efficiently transferred to draining lymph nodes in the body and can be easily ingested by dendritic cells to perform effective cross-presentation and induce cellular immunologic response. The aluminum adjuvant has strong Th1 immunologic response.

The present invention provides a novel wound dressing sheet having high liquid absorbency and strength. The wound dressing sheet of the present invention is characterized in that it is a wound dressing material containing carboxymethylated natural or regenerated cellulose fibers, and the average substitution degree of hydroxyl groups in glucose units constituting the cellulose is 0.3 or more and 1.0 or less. , and not less than 5% and not more than 80% of the carboxymethyl groups are protonated.

The invention discloses polymer microspheres modified by quaternary ammonium salt type hyperbranched polysulfide and a preparation method. In the present invention, under photoinitiated conditions, polyethylene glycol is used as a porogen, and alkyldithiol, propargyl glycidyl ether and 1,7-octadiyne are used as raw materials, and mercapto-alkyne addition suspension polymerization is used. Methods Prepared epoxy-based microporous polymer beads; then at 0°C, using methanol as a solvent, using ultraviolet light to trigger the reaction of allyl glycidyl ether and cysteamine hydrochloride to synthesize α‑epoxy‑ω ‑ammonium-based intermediate; then, in a solvent and at 60°C, epoxy-based microporous polymer beads, α-epoxy-ω-ammonium-based intermediate and sodium methoxide synthesize hyperbranched polysulfide ammonium in one step Modified polymer microspheres. The obtained product has a good killing effect on Escherichia coli, and the modified polymer microspheres can be recovered and reused through simple filtration.

The invention discloses a preparation method of a biologically absorbable polyphosphate and amino acid copolymer material. The preparation method comprises the following steps: 1) dehydrating alpha-amino acid and caprolactam under the protection of inert gas at 150 DEG C to 200 DEG C; 2) reacting at 190 DEG C to 260 DEG C and finishing polymerization reaction to form a polymer with a multi-component amino acid amide structure; 3) adding phosphate and reacting at 200 DEG C to 260 DEG C for 0.5h to 2h and finishing ring-opening copolymerization reaction; cooling to room temperature under the protection of the inert gas to obtain a product. A polyphosphate and amino acid copolymer prepared by the method has good hydrophilcity and degrading performance, and good mechanical properties; the pH (Potential of Hydrogen) of a degraded product is 6.5 to 7.5 and stimulation reaction is not caused; the polyphosphate and amino acid copolymer has good effect when being used for in-vivo repairing and has good clinical application prospect.
