Yin-chen Wu-ling powder alleviate cholestatic liver disease: Network pharmacological analysis and experimental validation.

BACKGROUND: Yin-chen Wu-ling Powder (YWP) has potential therapeutic effects on cholestatic liver disease (CLD), however, its active compounds and conceivable mechanism are as yet indistinct. METHODS: The network pharmacology and gene function annotation examined the multiple active ingredients, potential targets, and possible mechanisms of YWP in CLD treatment. Then the molecular docking reassured the reliability of the core compounds including the key genes and farnesoid X receptor (FXR). Finally, The Mdr2-/- mice were used to test the effect and mechanism of YWP against CLD. RESULTS: The network analysis identified nine main active ingredients, including quercetin, capillarisin, eupalitin, isorhamnetin, skrofulein, genkwanin, cerevisterol, gederagenin, and sitosterol. The PPI network predicted the ten hub genes involved were AKT1, MAPK1, MAPK14, IL6, RXRA, ESR1, IL10, NCOA1, CAV1, and EGFR. The KEGG and GO analysis showed that YWP might contribute to CLD treatment through the PI3K/Akt and MAKP signalings to manage pathological reactions, for instance, inflammatory responses. The molecular docking displayed a functional similarity among the core compounds with ursodeoxycholic acid (UDCA) and Obeticholic acid (OCA) on the effects on AKT1, MAPK1, MAPK14, RXRA, and ESR, and the affinity to FXR. In addition, the YWP could significantly attenuate hepatic injury and improve inflammatory response in Mdr2-/- mice. The mechanism exploration showed that YWP mainly decreased inflammatory response by inhibiting AKT/P38MAPK signaling. CONCLUSION: This study firstly revealed the multiple active ingredients, potential targets, and possible mechanism of YWP to treat CLD based on network pharmacology Analysis and molecular docking. YWP could alleviate cholestasis in Mdr2-/- mice by impairing inflammation via inhibiting AKT/P38MAPK Signaling.

Application of herbs and active ingredients ameliorate non-alcoholic fatty liver disease under the guidance of traditional Chinese medicine.

Non-alcoholic fatty liver disease (NAFLD) is a global health problem, and its prevalence has been on the rise in recent years. Traditional Chinese Medicine (TCM) contains a wealth of therapeutic resources and has been in use for thousands of years regarding the prevention of liver disease and has been shown to be effective in the treatment of NAFLD in China. but the molecular mechanisms behind it have not been elucidated. In this article, we have updated and summarized the research and evidence concerning herbs and their active ingredients for the treatment in vivo and vitro models of NAFLD or NASH, by searching PubMed, Web of Science and SciFinder databases. In particular, we have found that most of the herbs and active ingredients reported so far have the effect of clearing heat and dispelling dampness, which is consistent with the concept of dampness-heat syndrome, in TCM theory. we have attempted to establish the TCM theory and modern pharmacological mechanisms links between herbs and monomers according to their TCM efficacy, experiment models, targets of modulation and amelioration of NAFLD pathology. Thus, we provide ideas and perspectives for further exploration of the pathogenesis of NAFLD and herbal therapy, helping to further the scientific connotation of TCM theories and promote the modernization of TCM.

Ganji Formulation for Patients with Hepatocellular Carcinoma Who Have Undergone Surgery: A Multicenter, Randomized, Double-Blind, Controlled Trial.

Objective. To ascertain the efficacy and safety of Ganji Formulation (GF) for patients with Hepatocellular carcinoma (HCC) who had undergone surgery. Materials and Methods. A total of 262 HCC patients who had undergone liver resection, local ablation, or transcatheter arterial chemoembolization (TACE) were divided randomly into the treatment group and control group. The former was treated with GF and the later with placebo, both for 6 months. The primary endpoint was overall survival (OS). Second endpoints were disease-free survival (DFS) or time to disease progression (TTP). Results. OS of the treatment group was significantly longer than that of the control group (P < 0.05). Subgroup analysis showed that, for patients who received TACE, the TTP was significantly longer in the treatment group than in the control group (P < 0.05). However, for patients who underwent liver resection or local ablation, there was no significant difference in DFS between the two groups (P > 0.05). Conclusion. GF could improve postoperative cumulative survival and prolong the TTP. This clinical trial number is registered with ChiCTR-IOR-15007349.

Metabolic modulation of acetaminophen-induced hepatotoxicity by osteopontin.

Induction of osteopontin (OPN), a well-known pro-inflammatory molecule, has been observed in acetaminophen (APAP)-induced hepatotoxicity. However, the precise cell source for OPN induction and its role during APAP-induced hepatotoxicity has not been fully explored. By employing a hepatotoxic mouse model induced by APAP overdose, we demonstrate that both serum and hepatic OPN levels were significantly elevated in response to APAP treatment. Our in vivo and in vitro studies clearly indicated that the induced expression of hepatic OPN was mainly located in necrosis areas and produced by dying or dead hepatocytes. Functional experiments showed that OPN deficiency protected against the APAP-induced liver injury by inhibiting the toxic APAP metabolism via reducing the expression of the cytochrome P450 family 2 subfamily E member 1 (CYP2E1). Interestingly, this inhibition of CYP2E1 expression did not occur in unfasted Opn-/- mice, but was significant in fasted Opn-/- mice and maintained for 2 hours after APAP challenge in fasted Opn-/- mice. In addition, despite the early protective role of OPN deficiency on APAP-induced hepatotoxicity, OPN deficiency retarded injury resolution by sensitizing hepatocytes to apoptosis and impairing liver regeneration. Finally, we demonstrated that a siRNA-mediated transient hepatic Opn knockdown could sufficiently and significantly protect animals from APAP-induced hepatotoxicity and death. In conclusion, this study clearly defines the cell source of OPN induction in response to APAP treatment, provides a novel insight into the metabolic role of OPN to APAP overdose, and suggests an Opn-targeted therapeutic strategy for the treatment or prevention of APAP-induced hepatotoxicity.

Simple and Efficient Chromophoric-Fluorogenic Probes for Diethylchlorophosphate Vapor.

In this work, we developed two small-molecule probes for real-time and onsite detecting of diethylchlorophosphate (DCP) vapor by incorporating amine groups into Schiff base skeletons. Both probes can be easily synthesized with high yield through one-step and low-cost synthesis. They can detect DCP vapor in the chromophoric-fluorogenic dual mode, which combines both the advantages of the visualization of color sensing and the high sensitivity of the fluorescence sensing. Furthermore, its sensing is based on the "turn-on" mode which can avoid the interference arising from photobleaching or fluorescence quenching agents based on "turn-off" mode. The detection limit was quantified to be as low as 0.14 ppb.
