Differences in Effects of Zuojin Pills(左金丸)and Its Similar Formulas on Wei Cold Model in Rats

Objective:To explore the effects of Zuojin Pills(左金丸)and its similar formulas on the stomach cold syndrome in a Wei cold model in rats.Methods:The rat Wei cold model was established by intragastric administration of glacial NaOH,and the gastric mucosa injury indices,together with the levels of motilin and gastrin in the stomach,were determined.The preventive and curative effects of Zuojin Pills and its similar formulas on gastric mucosa injury were investigated.Results:Zuojin Pills and its similar formulas ...

Mechanism of Zuojin Pill in the treatment of anxiety disorder and Major depressive disorder based on network pharmacology and molecular docking validation

Background:Zuojin Pill(ZJP)is a classic Chinese herbal prescription with good efficacy in the treatment of Anxiety disorder(AD)and Major depressive disorder(MDD).Nevertheless,the potential mechanisms of ZJP remain unclear.Based on network pharmacology and molecular docking methods,this study aims to elucidate the possible mechanism of ZJP in the treatment of AD and MDD.Methods:The components and targets of Rhizoma Coptidis and Fructus Evodiae were collected from TCMSP,ETCM,HERB,SWISSADME and STITCH databases.The disease targets related to MDD and AD were collected from DISGENET,GENECARDS and OMIM databases.Protein-protein interaction network was constructed by STRING database,GO and KEGG enrichment analysis was performed by METASCAPE database,and“drugs-components-targets network”was constructed by Cytoscape software.Molecular docking verification was performed by Sailvina2.0 software.Results:ZJP may act on AKT1,IL6,TNF and other targets through caffeine,isorhamnetin,berberine and other components,regulating the Inflammatory mediator regulation of TRP channels,Serotonergic synapse,Dopaminergic synapse,PI3K/AKT signaling pathway,and other pathways.The results of molecular docking showed that berberine had the best binding activity with the core target.Conclusion:ZJP can exert anti-anxiety and anti-depression effects through multiple components,multiple targets and multiple pathways.

Extract of Zuojin Pill (左金丸) Induces Apoptosis of SGC-7901 Cells via Mitochondria-Dependent Pathway

Objective： To observe the effects of water extract of Zuojin Pill （左金丸, ZJP） on inhibiting the growth of human gastric cancer cell line SGC-7901 and its potential mechanism. Methods： Effects of ZJP on SGC-7901 cells growth were determined by 3-（4,5-dimethyl-2-thiazolyl）-2,5-diphenyl-2-H-tetrazolium bromide （MTT） assay, cell apoptosis and cell cycle were determined by flow cytornetry, and apoptosis induction was detected by means of DNA gel electrophoresis. The cellular mechanism of drug-induced cell death was unraveled by assaying oxidative injury level of SGC-7901 cell, mitochondrial membrane potentials, expression of apoptosis-related genes, such as B cell lymphoma/lewkmia-2 （Bcl-2）, Bcl-2 associated X protein （Bax） and cleaved caspase-3 and caspase-9. Results： ZJP exerted evident inhibitory effect on SGC-7901 cells by activating production of reactive oxygen species and elevating Bax/Bcl-2 ratio in SGC-7901 cells, leading to attenuation of mitochondrial membrane potential and DNA fragmentation. Conclusions： ZJP inhibits the cancer cell growth via activating mitochondria-dependent apoptosis pathway. ZJP can potentially serve as an antitumor agent.
