The invention provides a flexible plastic magnetic diaphragm material with regenerated plastics, which is prepared from the following raw material components in percentage by weight: 72 to 85 percent of magnetic powder, 0 to 28 percent of regenerated plastics, 0 to 28 percent of thermoplastic plastics and 0 to 3 percent of assistant. The method for preparing the flexible plastic magnetic diaphragm material comprises: mixing the magnetic powder, the regenerated plastic, the thermoplastic plastics and the assistant in a ratio; extruding the mixture in an extruder to cast a film; and cooling and setting film by two rolls or a plurality of rolls to obtain the product. In the invention, the repeated use of the regenerated plastics in the plastic magnetic material is realized, oil resource is saved and carbon emission is reduced; meanwhile, the flexible plastic magnetic diaphragm material which is thinner and wider than rubber magnetic material can be prepared.

The invention relates to a class of long-acting glucagon-like peptide-1 (GLP-1) analogs and a synthesis method thereof. GLP-1 analogues with longer pharmacological action time were obtained by modifying GLP-1. The synthesis of the target polypeptide was quickly realized through the solid-phase synthesis method of orthogonal protection strategy. The crude product was purified and lyophilized to obtain GLP-1 analogues. thing.

The invention relates to the technical field of bobbin winders, in particular to a method for preparing mixed-color single yarns and a device for implementing the method, and aims to solve the problems that the conventional mixed-color single yarn product has a monotonous color, fibers of single-color yarns are not blended, and plied yarns are simply twisted. The method is characterized by comprising the following steps of: selecting the single-color yarns according to the color design requirement, wetting the single-color yarns in a water tank, untwisting each strand of single-color yarns, performing pressing multi-strand mixing drafting, and twisting to form a strand of mixed-color single yarns. Industrial automatic production is easy to implement, the mixed-color single yarn product has abundant colors, a braided fabric is high in third dimension and personality and has a unique style, and the method is suitable for preparing the mixed-color single yarns made of various materials such as flax, cotton, fibers and silk.

The invention is a long-acting exenatide derivative, which belongs to the technical field of polypeptide compounds. The exenatide derivative is structurally optimized for the exenatide sequence, so that it has hypoglycemic and weight-reducing effects at the same time, and double the amount of exenatide is conjugated with a single amount of fatty acid chains. The fatty acid chain plays a binding role with serum albumin to obtain exenatide derivatives with longer pharmacological action time. The invention also discloses a preparation method of exenatide derivatives, a pharmaceutically acceptable salt of exenatide derivatives, a pharmaceutical composition of exenatide derivatives, a pharmaceutical composition and a use thereof. Application of the derivative in the preparation of medicines for treating and / or preventing diabetes, obesity, hyperlipidemia and non-alcoholic fatty liver. The long-acting exenatide derivatives can reduce the weight on the basis of retaining the hypoglycemic activity, and the biological half-life is significantly longer than that of the exenatide prototype, and some of them have reached more than 36 hours, which greatly prolongs the hypoglycemic effect. Time of bariatric action.

The invention relates to the design and synthesis method of a novel long-acting hypoglycemic peptide. Exendin-4 derivatives with longer pharmacological action time were obtained by modifying Exendin-4. The synthesis of the target polypeptide was quickly realized through the solid phase synthesis method of orthogonal protection strategy. The crude product was purified and lyophilized to obtain long-acting chemical derivatives. Glycopeptides.
