Abstract:
ObjectiveTo investigate the mechanism of Renshen Guben oral liquids（RGOL） in treatment of mice with renal fibrosis based on metabolomics and network pharmacology. MethodC57BL/6 mice were randomly divided into control group， model group and RGOL group， 12 mice in each group. Except for the control group， mice in the other groups were induced into unilateral ureteral obstruction（UUO） model by UUO. After preparation of the model， an aqueous solution of 4.2 g·kg-1 extract powder was administered by gavage to RGOL group for 14 d， and an equal amount of distilled water was administered by gavage to the control and model groups. After the last administration on the 14th day， urine was collected and detected by ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry（UPLC-QQQ-MS/MS） with 0.1% formic acid aqueous solution as mobile phase A， and acetonitrile-isopropanol（70∶30） as mobile phase B for gradient elution（0-1 min， 5%B； 1-5 min， 5%-30%B； 5-9 min， 30%-50%B； 9-11 min， 50%-78%B； 11-13.5 min， 78%-95%B； 13.5-14 min， 95%-100%B； 14-16 min， 100%B； 16-16.1 min， 100%-5%B； 16.1-18 min， 5%B）， column temperature of 40 ℃， flow rate of 0.4 mL·min-1， electrospray ionization（ESI）， collection range of m/z 50-900. Through network pharmacology， the targets of components in RGOL and the targets of renal fibrosis were analyzed interactively， and the key components and key targets were screened by network topology analysis， and DAVID platform was used to predict the signaling pathways of RGOL for the treatment of renal fibrosis. ResultA total of 7 differential metabolites involving 8 metabolic pathways were identified in RGOL for the treatment of renal fibrosis. The network pharmacology revealed that 36 key components in RGOL were related to 7 differential metabolites， mainly ginsenosides， notoginsenosides and nucleotides. Based on the herbs-components-targets-pathways network， a total of 23 key targets related to the treatment of renal fibrosis by RGOL were highlighted， which together with the differential metabolites were involved in linoleic acid metabolism， arginine biosynthesis， tricarboxylic acid cycle（TCA）， arginine and proline metabolism and other pathways. ConclusionBased on metabolomics and network pharmacology， this study preliminarily identified 7 differential metabolites， 36 potential pharmacodynamic components and 23 key targets and 4 key pathways in RGOL for the treatment of renal fibrosis， providing an experimental basis for the clinical application and mechanism study of this preparation.
