The classic prescription Zuojin Pill (ZJP) shows a good therapeutic effect on chronic atrophic gastritis (CAG); it is of great significance to clarify its specific mechanism. Therefore, we explore the mechanism of ZJP on MNNG-induced CAG by integrating approaches. First of all, through the pathological changes of gastric tissue and the expression level of PGI and PGI/II in serum, the expression of inflammation-related factors was determined by RT-PCR to determine the efficacy. Then, UPLC-Q-TOF/MS was used for plasma and urine metabolomic analysis to screen the specific potential biomarkers and metabolic pathway of ZJP in ameliorating CAG and to explore its possible mechanism. ZJP significantly ameliorate the pathological injury of gastric tissue, increase levels of PGI and PGI/II, and reduce the expression level of proinflammatory factors. Through metabolomic analysis, 9 potential metabolic differences were identified and 6 related metabolic pathways were enriched. These findings indicate for the first time the potential mechanism of ZJP in improving CAG induced by MNNG and are of great significance to the clinical development and application of ZJP-related drugs.

This study aimed to investigate the inhibitory effect of Zuojin Pill (ZJP) on KYSE 150 cells and xenograft tumours of the digestive tract cancer – esophageal cancer (EC) and its underlying mechanism. Initially, in vivo research demonstrated that oral administration of ZJP effectively inhibited the growth of EC tumours, and in vitro studies revealed that ZJP suppressed the proliferation, migration, and invasion of cells. Then, network pharmacology prediction identified the core target, active ingredient, and involvement of the PI3K-Akt signalling pathway in ZJP treatment of EC. Cell studies validated that ZJP affected the expression of core targets, and its active ingredients inhibited the proliferation of cells. Additionally, ZJP was shown to induce cell apoptosis, decrease mitochondrial membrane potential, and increase the level of intracellular oxidative stress. Further experimental verifications suggested that the inhibitory effects of ZJP on EC might be attributed to the modulation of PI3 K/Akt signalling pathways.

Background Precancerous lesions of gastric cancer (PLGC) represent critical stages in gastric cancer progression, with a high risk of malignancy. Current treatments, such as Helicobacter pylori eradication, show limited efficacy in reversing precancerous molecular changes. Zuojin Pill (ZJP), a traditional Chinese medicine, has demonstrated potential for treating digestive disorders and may offer a promising approach for PLGC intervention.Objective This study aims to investigate the therapeutic effects and mechanisms of ZJP in treating PLGC, focusing on its active components, target pathways, and molecular interactions. By using advanced analytical techniques, we provide a scientific foundation for ZJP’s potential application in early gastric cancer intervention.Methods Using ultra-high performance liquid chromatography-quadrupole orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap HRMS), we identified active components in ZJP. A network pharmacology approach was then applied to construct a “ZJP-compound-target-disease” network. Molecular docking and molecular dynamics simulations were conducted to analyze the stability and interactions of the main active components of ZJP with core protein targets in PLGC. Animal experiments were used to validate significant targets and pathways in vivo.Results Tangeritin, Isorhamnetin, Caffeic Acid, Azelaic Acid, and Adenosine were identified as the main active components of ZJP in the treatment of PLGC, with key targets including PIK3R1, MAPK3, SRC, JAK2, STAT3, and PIK3CA. Molecular docking and molecular dynamics simulations further confirmed the relationship between compounds and target proteins. The potential molecular mechanism of ZJP predicted by network pharmacology analysis was confirmed in PLGC rats. ZJP downregulated IL-6, TNF-α, c-myc, p-MEK1 and p-ERK1/2, effectively reversing the progression of PLGC.Conclusion ZJP can reverse MNNG-induced PLGC, potentially through inhibition of the MEK/ERK/c-myc pathway and regulation of cellular proliferation and apoptosis.

Ethnopharmacological relevance Zuojin Pill (ZJP) is a classic prescription composed of Coptis chinensis and Tetradium ruticarpum (A.Juss.) T.G.Hartley, which is often used in the treatment of digestive system diseases . Aim of this study The purpose of this study was to explore the therapeutic effect and potential mechanism of ZJP on chronic atrophic gastritis (CAG) induced by MNNG . Materials and methods The GES-1 and rat model of CAG was established by MNNG. Detection of cell viability, morphological changes and proliferation of GES-1 by CCK-8 and high content screening (HCS) assay. G-17, IL-8 and TNF-α in rat serum were detected by ELISA kit. The expression of related mRNA and protein on TGF-β1/PI3K/Akt signal axis were detected by RT-PCR and Western blot . Results The results showed that ZJP could significantly improve the GES-1 damage induced by MNNG and improve the gastric histomorphology of CAG rats. The intervention of ZJP could significantly reduce the content of G-17 and inflammatory factors IL-8, TNF- α, IL-6 and IL-1β, inhibit the expression of TGF-β1, PI3K and their downstream signals p-Akt, p-mTOR, P70S6K, and promote the expression level of PTEN, LC3-II and Beclin-1. Conclusion ZJP has a good therapeutic effect on CAG induced by MNNG, which may be closely related to the inhibition of TGF-β1/PI3K/Akt signal pathway.
