Exploring the mechanism of Jianpi Huatan recipe in protecting hepatocellular carcinoma based on network pharmacology.

ETHNOPHARMACOLOGICAL RELEVANCE: Jianpi Huatan Recipe (JPHTR) is an effective prescription for delaying progression of hepatocellular carcinoma (HCC) provided by Longhua Hospital affiliated to Shanghai University of traditional Chinese Medicine, and it is consisted of nine traditional Chinese drugs, but the protective mechanism of JPHTR against HCC progression is unclear. AIM OF THE STUDY: To study the mechanism of JPHTR preventing the progression of HCC based on the network pharmacology. MATERIALS AND METHODS: The chemical component and potential gene targets of JPHTR and the important gene targets of HCC were obtained by retrieving traditional Chinese medicine network pharmacology analysis system (TCMNPAS) database. The data obtained from the database are used to construct the drugs-chemical component-targets network and protein-protein interaction network by using Cytoscape software and STRING database. The potential targets of JPHTR and HCC targets were imported into TCMNPAS-related modules in order to obtain the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment pathways. Finally, we used HCC rat model to verify the vital signaling pathways predicted by network pharmacology. RESULTS: A total of 197 potential compounds and 721 potential targets of JPHTR and 611 important gene targets of HCC were obtained. Through the experiment in vivo, it was found that JPHTR can reduce the serum levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase, reduce the lipid droplets and inflammatory injury of liver tissue, and reduce the mRNA expression of Interleukin-6 (Il-6), Janus tyrosine Kinase2 (Jak2) and Forkhead box O3 (Foxo3) in FOXO pathway in the liver, thus delaying the development of HCC. CONCLUSION: Through network pharmacology and rat experiments, it is preliminarily confirmed that JPHTR may delay the progression of HCC by regulating the expression of Il-6/Jak2/Foxo3 in FOXO signal pathway, which is expected to be a new therapeutic target for the protection of HCC.

Qinggan Huoxue Recipe attenuates Alcoholic Liver Disease by suppressing PI3K/AKT signaling pathway based on network pharmacology.

Qinggan Huoxue Recipe (QGHXR) is originated from Xiao Chaihu Decotion. Many experimental studies have confirmed that QGHXR can significantly alleviate the symptoms of alcoholic liver disease (ALD), but the detailed mechanism is still unclear. Using traditional Chinese medicine network pharmacology analysis system database and animal experiments, we found that 180 potentially chemical compositions and 618 potential targets were screened from the prescription, which shared 133 signal pathways with ALD. Through animal experiments, it was found that QGHXR could reduce the liver total cholesterol (TC), serum TC, alanine aminotransferase, aspartate aminotransferase of ALD mice, reduce the lipid droplets and inflammatory injury of liver tissue. Meanwhile, it can also increase PTEN, decrease PI3K and AKT mRNA levels. In this study, we obtained the targets and pathways of QGHXR in the treatment of ALD, and preliminatively verified that QGHXR may improve ALD through PTEN/PI3K/AKT signaling pathway.

Application of metabolomics in the diagnosis of non-alcoholic fatty liver disease and the treatment of traditional Chinese medicine.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease around the world, and it often coexists with insulin resistance-related diseases including obesity, diabetes, hyperlipidemia, and hypertension, which seriously threatens human health. Better prevention and treatment strategies are required to improve the impact of NAFLD. Although needle biopsy is an effective tool for diagnosing NAFLD, this method is invasive and difficult to perform. Therefore, it is very important to develop more efficient approaches for the early diagnosis of NAFLD. Traditional Chinese medicine (TCM) can play a certain role in improving symptoms and protecting target organs, and its mechanism of action needs to be further studied. Metabolomics, the study of all metabolites that is thought to be most closely associated with the patients' characters, can provide useful clinically biomarkers that can be applied to NAFLD and may open up new methods for diagnosis. Metabolomics technology is consistent with the overall concept of TCM, and it can also be used as a potential mechanism to explain the effects of TCM by measuring biomarkers by metabolomics. Based on PubMed/MEDLINE and other databases, this paper retrieved relevant literature NAFLD and TCM intervention in NAFLD using metabolomics technology in the past 5 years were searched, and the specific metabolites associated with the development of NAFLD and the potential mechanism of Chinese medicine on improving symptoms were summarized.
