OBJECTIVE: To explore the material basis of the difference of efficacy of Dahuang(Radix Et Rhizoma Rhei Palmati)-Taoren(Semen Persicae)(DT) drugs with different proportions. METHODS: Samples of different ratios of Dahuang(Radix et Rhizoma Rhei Palnati, DH) to Taoren(Semen Persicae, TR)(Group A 1∶1, B 2∶3, C 3∶2) were analyzed based on gas chromatography time-of-flight mass spectrometry untargeted metabolomics technique. RESULTS: A total of 240 primary metabolites were detected. Forty-one differential metabolites involved nine differential metabolic pathways, of which four were closely related to the efficacy of DT in the treatment of heat and blood stasis syndrome. These pathways included the biosynthesis of amino acid(phenylalanine tyrosine and tryptophan), flavonoids, unsaturated fatty acids, and the glycolysis/glycogenesis pathway. CONCLUSION: There are significant differences in the efficacy of different ratios of DT drugs, and their optimal ratio for the treatment of heat and blood stasis syndrome should be 1∶1.

Objective: To identify the core targets of Rheum palmatum L. and Salvia miltiorrhiza Bge.,(Dahuang-Danshen, DH-DS) and the mechanism underlying its therapeutic efficacy in acute pancreatitis(AP)using a network pharmacology approach and validate the findings in animal experiments. Methods: Network pharmacology analysis was used to elucidate the mechanisms underlying the therapeutic effects of DH-DS in AP. The reliability of the results was verified by molecular docking simulation and molecular dynamics ***, the results of network pharmacology enrichment analysis were verified by immunohistochemistry,Western blot analysis and real-time quantitative PCR, respectively. Results: Sixty-seven common targets of DH-DS in AP were identified and mitogen-activated protein kinase 3(MAPK3), Janus kinase 2(JAK2), signal transducer and activator of transcription 3(STAT3), protein c-Fos(FOS) were identified as core targets in the protein interaction(PPI) network analysis. Gene ontology analysis showed that cellular response to organic substance was the main functions of DH-DS in AP, and Kyoto Encyclopedia of Genes and Genomes analysis showed that the main pathway included Th17 cell differentiation. Molecular docking simulation confirmed that DH-DS binds with strong affinity to MAPK3, STAT3 and FOS. Molecular dynamics simulation revealed that FOS-isotanshinone Ⅱ and STAT3-dan-shexinkum d had good binding capacity. Animal experiments indicated that compared with the AP model group, DH-DS treatment effectively alleviated AP by inhibiting the expression of interleukin-1β, interleukin-6 and tumor necrosis factor-α, and blocking the activation of Th17 cell differentiation(P<0.01). Conclusion: DH-DS could inhibit the expression of inflammatory factors and protect pancreatic tissues,which would be functioned by regulating Th17 cell differentiation-related m RNA and protein expressions.

Chlorogenic acid (CA) is a natural plant-derived polyphenol compound that is widely present in beverages (coffee and tea)， fruits (blueberry， apple， and mulberry)， and medicinal plants (Lonicera japonica， Eucommia ulmoides， and Cichorium intybus). In recent years， CA has attracted extensive attention due to its various health benefits， such as anti-inflammatory， immunomodulatory， anti-obesity， anti-diabetes mellitus， and neuroprotection activities. Interestingly， the low bioavailability of CA corresponds to high bioactivity， which raises a key scientific question of how low bioavailability CA can achieve high biological activity. In this review， we highlight the gut microbiota as a key target for connecting the two by summarizing a large amount of evidence. Specifically， the composition and abundance of gut microbiota， its metabolites， intestinal immunity， barrier function and so on were all changed under different pathological conditions such as inflammatory bowel disease， liver disease， kidney disease， cardiovascular disease， diabetes mellitus， obesity， etc. Conversely， these changes could be reversed by CA. In a word， CA could achieve pharmacological activity as well as health-protective effects by modulating intestinal immune and barrier function， gut microbiota composition， gut microbiota metabolites， and signaling pathways. This review provides new targets for the prevention and treatment of diseases by CA. Meanwhile， regulating the composition of the gut microbiota through natural products may be a potential strategy to achieve health protection.
