Project description:To study the effect of Radix Paeoniae Rubra decoction on tolerance of Staphylococcus aureus.The effect of Radix Paeoniae Rubra on the resistance of Staphylococcus aureus to oxacillin sodium was studied by millipore dilution method in this experiment.At the same time ,conducted on transcriptome analysis of Staphylococcus aureus related genes in Radix Paeoniae Rubra.And to detect the expression level of related genes of Staphylococcus aureus under the action of Radix Paeoniae Rubra by PCR technology.The tolerance of Staphylococcus aureus was decreased obviously when the concentration of Radix Paeoniae Rubra decoction was above 1mg/ml.The effect of Radix Paeoniae Rubra decoction on the expression of tolerance genes femB,pvL and gluM when the concentration of Radix Paeoniae Rubra decoction was above 4mg/ml.When rhe concentration of Radix Paeoniae Rubra is more than 1mg/ml,it can effectively reduce the resistance of Staphylococcus aureus to oxacillin sodium.The reason may be due to the effect of Radix Paeoniae Rubra on the resistance gene of Staphylococcus aureus.
Project description:Modern pharmacology has proved that Codonopsis Radix and its active ingredients can treat stomach diseases by ameliorating gastrointestinal motility and regulating oxidase levels. However, the detailed molecular mechanism is still unclear. In this study, we systematically evaluated the pharmacodynamic effects of Codonopsis Radix in Gastric Precancerous Lesions animal models. Considering the combination of proteomics and metabolomics, we found that CR could significantly reversed the biological pathways related to energy metabolism which were disturbed by GPL model. Furthermore, the results of serum pharmacology indicated that the Codonopsis Radix contained serum could ameliorate gastritis injury, and selectively inhibit the proliferation of gastric cancer cells rather than normal cells, which was closely related to ATP production in above cells.
