Food Sci Nutr 2024; 12:2068-2080. [PMID: 38455195 PMCID: PMC10916552 DOI: 10.1002/fsn3.3907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 11/19/2023] [Accepted: 12/08/2023] [Indexed: 03/09/2024] Open
Abstract
Studies suggest that mangiferin (MAF) has good therapeutic effects on chronic bronchitis and hepatitis. Also, it is one of the antiviral ingredients in Anemarrhena asphodeloides Bunge. However, its effect on the LPS-induced inflammation and intestinal flora during sepsis remains unclear yet. In the present study, LPS-stimulated inflammation RAW264.7 cells and LPS-induced sepsis mice were used to evaluate the efficacy of MAF in vitro and in vivo. 16S rDNA sequencing was performed to analyze the characteristics of intestinal flora of the sepsis mice. It has been demonstrated that MAF (12.5 and 25 μg/mL) significantly inhibited protein expressions of TLR4, MyD88, NF-κB, and TNF-α in the LPS-treated cells and reduced the supernatant TNF-α and IL-6 levels. In vivo, MAF (20 mg/kg) markedly protected the sepsis mice and reduced the serum TNF-α and IL-6 levels. Also, MAF significantly downregulated the protein expressions of TLR4, NF-κB, and MyD88 in the livers. Importantly, MAF significantly attenuated the pathological injuries of the livers and small intestines. Further, MAF significantly increased proportion of Bacteroidota and decreased the proportions of Firmicutes, Desulfobacterota, Actinobacteriota, and Proteobacteria at phylum level, and it markedly reduced the proportions of Escherichia-Shigella, Pseudoalteromonas, Staphylococcus at genus level. Moreover, MAF affects some metabolism-related pathways such as citrate cycle (TCA cycle), lipoic acid metabolism, oxidative phosphorylation, bacterial chemotaxis, fatty acid biosynthesis, and peptidoglycan biosynthesis of the intestinal flora. Thus, it can be concluded that MAF as a treatment reduces the inflammatory responses in vitro and in vivo by inhibiting the TLR4/ MyD88/NF-κB pathway, and corrects intestinal flora imbalance during sepsis to some degree.

Inhibition of circulating exosomes release with GW4869 mitigates severe acute pancreatitis-stimulated intestinal barrier damage through suppressing NLRP3 inflammasome-mediated pyroptosis. Int Immunopharmacol 2024; 126:111301. [PMID: 38016345 DOI: 10.1016/j.intimp.2023.111301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 11/16/2023] [Accepted: 11/24/2023] [Indexed: 11/30/2023]
Abstract
Intestinal barrier dysfunction frequently occurs as a complication in cases of severe acute pancreatitis (SAP); however, no effective therapeutic methods are available because the precise mechanism remains obscure. Recent research has elucidated the role of circulating exosomes in the progression of SAP. Therefore, the present study explored whether inhibiting circulating exosomes release would improve intestinal barrier injury triggered via SAP and investigated the possible underlying mechanism. In vivo, we found that circulating exosomes release exhibited a considerable increase in SAP rats than in SO rats, and GW4869, a suppressor of exosomes release, significantly decreased exosomes release in SAP rats. We also observed that GW4869 suppressed NLRP3 inflammasome-mediated pyroptosis within the intestine and alleviated intestinal barrier injury within SAP. Moreover, the inflammatory response and remote organ (kidney and lung) injury associated with SAP improved after GW4869 treatment. In vitro, we confirmed that depletion of exosomes with GW4869 could partially abolish the destructive effects of SAP rat plasma on the viability and barrier function of IEC-6 cells. In summary, our findings show that the suppression of the release of circulating exosomes effectively inhibits the process of pyroptosis mediated by the NOD-like receptor protein 3 (NLRP3) inflammasome and, therefore, mitigates intestinal barrier dysfunction in SAP, suggesting that circulating exosomes may be a potential target for treating SAP.

[PMID: 38181043 PMCID: PMC10769011 DOI: 10.1371/journal.pone.0296641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 12/11/2023] [Indexed: 01/07/2024] Open
Abstract
This study aimed to evaluate the therapeutic efficacy and effect of blood purification (BP) therapy on severe acute pancreatitis (SAP). Information on 305 patients (BP group 68, control group 237) diagnosed with SAP was retrieved from the Medical Information Mart for Intensive Care IV (MIMIC IV) database. Firstly, the influence of BP treatment was preliminarily evaluated by comparing the outcome indicators of the two groups. Secondly, multiple regression analysis was used to screen the mortality risk factors to verify the impact of BP on the survival outcome of patients. Then, the effect of BP treatment was re-validated with baseline data. Finally, cox regression was used to make the survival curve after matching to confirm whether BP could affect the death outcome. The results indicated that the BP group had a lower incidence of shock (p = 0.012), but a higher incidence of acute kidney injury (AKI) (p < 0.001), with no differences observed in other outcome indicators when compared to the control group. It was also found that the 28-day survival curve of patients between the two groups was significantly overlapped (p = 0.133), indicating that BP treatment had no significant effect on the survival outcome of patients with SAP. Although BP is beneficial in stabilizing hemodynamics, it has no effect on short- and long-term mortality of patients. The application of this technology in the treatment of SAP should be done with caution until appropriate BP treatment methods are developed, particularly for patients who are not able to adapt to renal replacement therapy.

Abstract
BACKGROUND The relationship between total cholesterol (TC) levels and the severity of hypertriglyceridemic acute pancreatitis (HTGAP) remains unclear. AIMS The aim of this study was to investigate the relationship between the levels of TC at admission with the severity of HTGAP, in order to apply it as a reliable predictor at early stage in clinical practice. METHODS We performed a cohort study including 249 patients with AHTGP between November 2012 and April 2022 in XuanWu Hospital. Fasting TC was assayed within 24 h of admission, age, gender, body mass index, hypertension, diabetes mellitus, drinking, smoking, neutrophil-lymphocyte ratio, C-reactive protein and glucose were recorded as confounding factors. To evaluate the relationship of TC and the severity of HTGAP, we used smooth curve fitting and a segmented regression model with adjustment of confounding factors to analyze the threshold effect between TC and SAP occurrence risk. RESULTS 249 Patients were enrolled. The incidence of SAP was 25.3% (63/249). A nonlinear relationship between TC level and the severity of HTGAP. 6.09 mmol/L was the optimal TC value associated with the lowest risk of SAP occurrence. Moreover, TC level was negatively correlated with risk of severe HTGAP occurrence for TC < 6.09 mmol/L (OR 0.45, 95% CI 0.23-0.85, P = 0.014) and positively correlated for TC > 6.09 mmol/L in HTGAP patients (OR 1.14, 95% CI 1.04-1.26, P = 0.006). CONCLUSIONS We found that serum TC level is nonlinearly associated with the severity of HTGAP, and it can be a reliable predictor for early intervention and intensive care.

Abstract
Acute pancreatitis (AP) is one of the most common acute abdomen. Inflammation and apoptosis are closely linked with AP development. Total flavonoids of Chrysanthemum indicum L (TFC) has been proved to inhibit inflammation and apoptosis. If TFC could suppress AP remains unclear. AP animal and cell models were established with Cerulein. The pancreatic tissue injury was measured with HE staining. Inflammatory factors were detected with ELISA method. The protein expression was evaluated with Western blotting. Inhibition of AP in vivo was achieved by TFC by inhibiting serum amylase, myeloperoxidase (MPO), and water content of pancreatic tissue. The increased inflammatory response and activation of NF-κB signaling pathway in AP rats were inhibited after TFC treatment. The activation of NF-κB signaling pathway, increase of cell apoptosis and inflammatory factors in AR42J cells were suppressed by TFC. We demonstrated that TFC could significantly inhibit AP through restraining serum amylase, MPO, water content of pancreatic tissue, inflammation levels, apoptosis, and NF-κB signaling pathway activation. This study might clarify the potential inhibition mechanism of TFC in AP development.

Abstract
Acute pancreatitis (AP), as a common cause of clinical acute abdomen, often leads to multi-organ damage. In the process of severe AP, the lungs and intestines are the most easily affected organs aside the pancreas. These organ damages occur in succession. Notably, lung and intestinal injuries are closely linked. Damage to ML, which transports immune cells, intestinal fluid, chyle, and toxic components (including toxins, trypsin, and activated cytokines to the systemic circulation in AP) may be connected to AP. This process can lead to the pathological changes of hyperosmotic edema of the lung, an increase in alveolar fluid level, destruction of the intestinal mucosal structure, and impairment of intestinal mucosal permeability. The underlying mechanisms of the correlation between lung and intestinal injuries are inflammatory response, oxidative stress, and endocrine hormone secretion disorders. The main signaling pathways of lung and intestinal injuries are TNF-α, HMGB1-mediated inflammation amplification effect of NF-κB signal pathway, Nrf2/ARE oxidative stress response signaling pathway, and IL-6-mediated JAK2/STAT3 signaling pathway. These pathways exert anti-inflammatory response and anti-oxidative stress, inhibit cell proliferation, and promote apoptosis. The interaction is consistent with the traditional Chinese medicine theory of the lung being connected with the large intestine (fei yu da chang xiang biao li in Chinese). This review sought to explore intersecting mechanisms of lung and intestinal injuries in AP to develop new treatment strategies.
