The invention belongs to the technical field of drug co-delivery, and particularly relates to a nano-platform based on attenuated bacterial outer membrane vesicles and capable of achieving co-delivery of siRNA and adriamycin and a preparation method of the nano-platform. The preparation method comprises the following steps: synthesizing an ROS response type cationic polymer PTP; the preparation method comprises the following steps: preparing aptamer-DOX; preparing an ROS (reactive oxygen species) response type positive electric nano core PTP / 47aD; extracting and purifying the [delta] msbB OMVs; synthesizing a target functional unit DSPE-PEG2k-Angiopep-2 (Distearoyl Phosphate Polyethylene Glycol 2k-Angiopep-2); finally, the ROS response type co-delivery nano platform AO (at) PTP / 47aD is prepared and obtained. The co-delivery nano-platform prepared by the invention is relatively small in particle size, uniform in morphology and relatively high in biological safety, and has no obvious damage to various tissues and visceral organs. The glioblastoma immunopotentiator can be used as a general platform for gene delivery, can also be used as an immune activator, is suitable for intravenous injection administration, and can comprehensively overcome immune resistance of glioblastoma.

The application discloses an LDH-based vaccine adjuvant and a preparation method and application thereof, and belongs to the technical field of aluminum adjuvant preparation of vaccines, and the preparation method comprises the following steps: mixing at least one of soluble magnesium salt, soluble zinc salt, soluble manganese salt and soluble calcium salt with soluble aluminum salt, and then performing a co-precipitation reaction with a sodium hydroxide aqueous solution in a colloid mill device, and performing crystallization to obtain LDH nanosheets; dispersing the LDH nanosheets in a PBS solution, adding a hepatitis B surface antigen molecule drug, uniformly mixing, and then performing centrifugation to obtain the LDH-based vaccine adjuvant. The LDH-based vaccine adjuvant can significantly promote the maturation of DC cells and the activation of T cells, and the total IgG level reflects the overall humoral immune response intensity of the body to vaccines or pathogens; the LDH-based vaccine adjuvant forms a "storage library" at an injection site to store antigens and slowly release the antigens, and the purpose of long-time continuous stimulation of the immune system in the body is achieved.

This invention relates to a traditional Chinese medicine composition, specifically a traditional Chinese medicine composition for treating diabetic nephropathy, belonging to the fields of medicine and health products. The traditional Chinese medicine composition of this invention is made from components comprising the following raw materials: yam, salvia miltiorrhiza, rosehip, turtle shell, cornus officinalis, dioscorea hypoglauca, cuscuta chinensis, oyster shell, and American ginseng. Through rational formulation, this traditional Chinese medicine composition utilizes the principle of clearing heat and removing dampness, with the synergistic effect of multiple drugs, to significantly reduce fasting blood glucose, improve glucose metabolism, lower low-density lipoprotein cholesterol and triglycerides, and raise high-density lipoprotein cholesterol to regulate lipid metabolism, reduce weight, and has no significant damage to liver and kidney function, with minimal side effects.

This invention proposes a novel decorative wrapping paper and its manufacturing process, relating to the field of decorative wrapping paper manufacturing technology. The paper includes a base layer and a coating layer. The base layer is a pretreated plant fiber-based paper, and the coating layer covers at least one surface of the base layer. The novel decorative wrapping paper and its manufacturing process allow sodium carboxymethyl cellulose and chitosan in the coating layer to form a dense film structure, blocking moisture penetration. Testing shows that the decorative wrapping paper exhibits no significant penetration or damage after contact with water within 24 hours, demonstrating significantly better water resistance than ordinary decorative wrapping paper. Glycerin enhances the flexibility of the coating layer, preventing the paper from becoming brittle and breaking after coating. Furthermore, both sodium carboxymethyl cellulose and chitosan are biodegradable materials with no environmental burden, solving the environmental problems associated with polyethylene-coated decorative wrapping paper. The coating layer and base layer are tightly bonded after pretreatment, preventing peeling and improving overall paper strength, allowing the packaging to maintain its shape for a long time, making it suitable for long-distance transportation.
