Background:Buyang Huanwu decoction(BHD)is a traditional Chinese medicine herbal formula used for treating hypertension,particularly in the later stages of hypertension when it is associated with intracerebral hemorrhage.This study aims to investigate the treatment mechanism of BHD to provide a basis for its clinical application in hypertension treatment.Methods:Network pharmacology analysis and cell culture experiments were performed to explore the potential proteins and mechanisms of action of BHD against hypertension.Bioactive compounds related to BHD were screened,and relevant targets associated with hypertension and BHD were retrieved.Molecular docking technology was used to identify the effective signaling pathway based on the Kyoto Encyclopedia of Genes and Genomes and protein-protein interaction network cores.Lastly,the effects and mechanisms of BHD on salt-sensitive hypertensive endothelial cells were investigated.Results:Ninety-three potential therapeutic targets for BHD and salt-sensitive hypertension were found to be closely associated with the PI3K/Akt/eNOS signaling pathway and oxidative stress.Cell experiments further indicated the pivotal role of endothelial cells in hypertension,and validation analysis showed that BHD significantly preserved cell morphology,suppressed oxidative stress reactions,activated the PI3K/Akt/eNOS signaling pathways,preserved normal endothelial cell function,and reduced cell apoptosis.Conclusion:BHD effectively activates the PI3K/Akt/VEGF signaling pathway,attenuates oxidative stress-induced injury in endothelial cells exposed to high salt levels,and mitigates apoptosis,supporting the use of traditional Chinese medicine BHD in the treatment of salt-sensitive hypertension. 展开更多

A series of novel p(N-isopropylacrylamide) (PNIPAM) hydrogels were synthesized by radical copolymerization of N-isopropylacrylamide (NIPAM) and 3-methacryloxypropyltrimethoxysilane (MPTMS). The copolymers were then crosslinked through hydrolysis of the siloxane in acetic acid/water mixed solvent. Beta-cyclodextrin (Beta-CD) was introduced into the polymeric networks by condensation of 3-glycidoxypropyltrimethoxysilane derived beta-cyclodextrin (KH560-beta-CD) with MPTMS under acidic condition. These gels were heterogeneous, porous and exhibited fast deswelling kinetics when the temperature was elevated to above lower critical solution temperature (LCST). The swelling ratios of the gels containing beta-CD at room temperature were higher than that of the normal PNIPAM hydrogel, which was caused by the lower crosslinking density in beta-CD contained gels. In comparison to that of the normal PNIPAM gel, the amount of loaded-drug in the hydrogel containing beta-CD was higher, and the release time of 5-fluorouracil (5-Fu) was prolonged, which was attributed to the formation of inclusion compounds between 5-Fu and beta-CD in gel network. 展开更多
