    Abstract:
    ETHNOPHARMACOLOGICAL RELEVANCE: Jianwei Xiaoyan Granule (JWXYG) is the traditional Chinese medicine preparation in Jiangyin Hospital Affiliated to Nanjing University of Chinese Medicine, which has been widely used in clinical treatment of chronic atrophic gastritis (CAG). However, the material basis and potential mechanism of JWXYG in the treatment of CAG are not clear. PURPOSE: To explore the material basis and potential mechanism of JWXYG in the treatment of CAG. METHODS: In this study, the components of JWXYG were analyzed by HPLC-Q-TOF-MS/MS. Then, the CAG model in rats established by a composite modeling method and MC cell model induced by MNNG were used to explore the improvement effect of JWXYG on CAG. Finally, the potential mechanism of JWXYG in the treatment of CAG was preliminarily predicted based on network pharmacology and validated experimentally. RESULTS: Thirty-one components of JWXYG were analyzed through HPLC-Q-TOF-MS/MS, such as albiflorin, paeoniflorin, lobetyolin firstly. Research results in vivo showed that the gastric mucosa became thinner, intestinal metaplasia appeared, the number of glands was reduced, the serum levels of PG I and PG II increased and the contents of G17 and IL-6 reduced in CAG model rats. After 4 weeks of JWXYG (2.70 g/kg) administration, these conditions were significantly improved. In addition, cell viability, migration, and invasion of MNNG-induced MC cells was inhibited by JWXYG treatment (800 μg/mL). Furthermore, the results of network pharmacology indicated that HIF-1 and VEGF signaling pathways might play important roles in the therapeutic process. Then the results of Western blot, immunohistochemistry and immunofluorescence confirmed that with JWXYG treatment, the increased expression of HIF-1α, VEGF and VEGFR2 in gastric issue of CAG rats were restrained. Eventually, potential components of JWXYG in the treatment of CAG were predicted through molecular docking to elucidate the material basis. CONCLUSION: JWXYG could inhibit angiogenesis by regulating HIF-1α-VEGF pathway to exert therapeutic effects on CAG. Our study explored the potential mechanisms and material basis of JWXYG in the treatment of CAG and provides experimental data for the clinical rational application of JWXYG.
