3results about How to "Improve pathological changes" patented technology

This invention relates to the application of mitochondrial formulations in the preparation of drugs for treating chronic obstructive pulmonary disease (COPD). The mitochondrial formulations contain active mitochondria isolated from healthy donor cells, with a particle size of 400–1000 nm, possessing normal mitochondrial membrane potential and ATP generation function, and capable of being internalized by mammalian COPD lung epithelial cells. In vitro cell experiments have confirmed that this mitochondrial formulation can repair CSE-induced mitochondrial dysfunction in lung epithelial cells, inhibit mPTP opening, reduce mtDNA leakage into the cytoplasm, thereby blocking the activation of the cGAS-STING signaling pathway and reducing the release of inflammatory factors such as IL-1β and TNF-α. In vivo experiments in COPD mouse models show that tail vein injection of the mitochondrial formulation can effectively accumulate in lung tissue, significantly improving lung pathological changes such as emphysema and collagen fiber deposition in model mice. This invention provides a novel strategy for COPD treatment based on repairing mitochondrial function and intervening in inflammatory signaling pathways.

This invention belongs to the field of traditional Chinese medicine preparations, and relates to the preparation method and application of a compound preparation of Yao Yu effervescent tablets with anti-rheumatoid arthritis effect. The compound preparation comprises the following traditional Chinese medicine components: 4 parts by weight of Dioscorea cirrhosa, 3 parts by weight of Tinleaf Vine, 2 parts by weight of Camphor Tree, 2 parts by weight of Rhus chinensis, 3 parts by weight of Rhododendron molle, 1 part by weight of Ephedra sinica, 2 parts by weight of Semi-Acer palmatum, 2 parts by weight of Gynostemma pentaphyllum, and 1 part by weight of Cinnamomum cassia. The preparation steps include: placing Dioscorea cirrhosa, Tinleaf Vine, Camphor Tree, Rhus chinensis, Rhododendron molle, Gynostemma pentaphyllum, Semi-Acer palmatum, Gynostemma pentaphyllum, and Cinnamomum cassia in 6000 parts by weight of 70% ethanol. Extract for 2 hours, repeat three times, filter, and combine the filtrates; concentrate, freeze-dry, pulverize, and pass through an 80-mesh sieve for later use; mix 27.5% freeze-dried powder with 26.45% citric acid, 34.11% sodium bicarbonate, 5.61% PEG6000, and 6.33% lactose evenly, pass through an 80-mesh sieve, and prepare a soft mass using anhydrous ethanol as a wetting agent; pass the soft mass through a 20-mesh sieve and dry at 37℃ for 30 minutes to obtain compound preparation granules; granulate through a 20-mesh sieve for granulation, add lubricant PEG6000 and mix evenly; compress into tablets to obtain compound preparation effervescent tablets. This invention, through pharmacological experiments, confirms that the Yaoyu effervescent tablet compound preparation has a good anti-rheumatoid arthritis effect: it can reduce local inflammatory mediators and serum IL-1β, IL-6, TNF-α, and PEG2 levels, downregulate MDA and increase SOD to improve oxidative stress, inhibit the expression of MMP3, COX-2, and P38 proteins in the synovial membrane, and reduce pathological tissue damage. The medium and high dose groups showed the best effect, and it has a good therapeutic and protective effect on the ankle joint of AA rats, with good clinical application value.
