The invention relates to a dexmedetomidine film agent and a preparation method thereof, the prescription components of the dexmedetomidine film agent comprise dexmedetomidine or a pharmaceutically acceptable salt thereof and a film-forming agent, and the mass ratio of dexmedetomidine to the film-forming agent is 1: (20-200); the film-forming agent is glucose polymer ether. The glucose polymer ether can be a cellulose ether derivative and / or a starch ether derivative. When the glucose polymer ether is a starch ether derivative, the formula further comprises a plasticizer. The preparation method comprises the following steps: coating slurry to prepare a film, and drying; the slurry comprises the prescription components of the dexmedetomidine and water. And the obtained film agent product is stable in quality.

Microorganisms and bioprocesses are provided that convert gaseous C1 containing substrates, such as syngas, producer gas, and renewable H2 combined with CO2, into nutritional and other useful bioproducts. Disclosed herein are microorganisms containing that are capable of growing on gaseous carbon dioxide, gaseous hydrogen, syngas, or combinations thereof. The application describes methods for production of glucose and the glucose polymer starch and other polysaccharides by CO2-fixing chemoautotroph strains. The invention includes a method of production wherein the organisms are cultivated microaerobically or aerobically in a bioreactor using CO2, H2 and O2 in an oxyhydrogen fermentation and methods for recovery and purification of secreted glucose, intracellular starch, and other polysaccharides.

This invention discloses an extracellular polysaccharide DSP-1 from the shell of a deep-sea fungus, *Subseptospora*, and its applications. Didymella keratinophila The fermentation product of SCAU273 was isolated and purified to obtain an extracellular polysaccharide DSP-1. This polysaccharide has a molecular weight of 4116 Da, a bibranched structure, and is mainly composed of glucose polymers. Further studies showed that DSP-1 can enhance the activity and promote the proliferation of RAW 264.7 macrophages over a wide concentration range (25–400 μg / mL). Furthermore, at certain concentrations, it dose-dependently promoted the secretion of NO, TNF-α, IL-6, and IL-1β by RAW 264.7 macrophages, exhibiting good immunomodulatory activity against RAW 264.7 macrophages. It shows broad prospects for the production and widespread application of environmentally friendly marine biological agents.

A drug delivery method and a composition. The drug delivery method comprises bringing an active ingredient in contact with an absorption enhancer containing a glucose polymer or a derivative thereof to form a mixture, and nasally administering the mixture. Further provided are a composition containing an active ingredient and a glucose polymer or a derivative thereof, and the use of the composition.

The invention discloses an application of polydextrose in improving the quality of wheat flour steamed buns. The polydextrose is prepared by taking glucose, sorbitol and citric acid as raw materials, and carrying out heating melting and vacuum polycondensation to obtain an irregular granular D-glucose polymer; the average polymerization degree of the polydextrose is 11-13, and the water content of the polydextrose is 0.8-1.3%. The polydextrose has a strong amorphous structure, more hydroxyl functional groups, lower water content and higher hygroscopicity, and can obviously improve the internal adhesion, softness and looseness of the steamed bun, improve the taste of the steamed bun and prolong the shelf life of the steamed bun.

The technology disclosed in this specification relates to carbohydrate composition comprising a plurality of glucose polymers comprising a mixture of 1-2, 1-3, 1-4, and 1-6 linkages and having a defined ratio of a sum of the 1,6 and the 1,4 linages to the 1,3. The composition made in process comprising mixing a solution comprising glucose syrup with acid and heating the solution to evaporate a portion of the liquid and then decreasing the pressure on the mixture to obtain the carbohydrate composition. The compositions can be used in conjunction with high potency sweeteners to replace nutritive sweeteners to replace for example to replace lost bulk. Also, the composition can be used to provide dietary fiber to edible compositions or are used as bulking agents.

This invention relates to the field of nanomedicine technology, and more particularly to a DNA nanodumbbell for targeted intrabacterial transport, its preparation method, and its applications. The invention provides a DNA nanodumbbell for targeted intrabacterial transport, comprising a glucose polymer, L-arginine, a photosensitizer, streptavidin, and Dum; wherein Dum is a single-stranded DNA modified with amino and biotinylate groups. This structure enables precise spatial arrangement and controllable loading of the photosensitizer, therapeutic drug, and polysaccharide, thereby playing a stepwise role in targeted bacterial delivery, phototherapy, and tissue repair. It effectively overcomes the limited targeting efficiency of traditional phototherapy within infected tissues, minimizes non-specific damage to healthy tissues during treatment, and precisely regulates the spatiotemporal sequence of tissue repair.
