Article Abstract
Background And Objective: Immune checkpoint inhibitors (ICIs) have shown remarkable efficacy against various cancers in clinical practice. However, ICIs can cause immune checkpoint inhibitor-associated pancreatic injury, often leading to drug withdrawal, and then patients must go to specialized treatment. The patients, their primary tumors are sensitive to ICIs therapy, may experience treatment delays due to such adverse reactions. Therefore, there is a need for systematic clinical researches on immune-related pancreatic toxicity to provide a clinical basis for its prevention and treatment.
Methods: This study involved the collection of data from patients treated with ICIs and addressed pancreatic injury with preemptive treatment before continuing ICIs therapy. Then, we also statistically analyzed the incidence of pancreatic injury in patients with different courses and combined treatment, and the success rate of rechallenge treatment.
Results: The study included 62 patients, with 33.9% (21/62) experiencing varying degrees of pancreatic injury. Patients with pancreatic injury, 10 cases evolved into pancreatitis, representing 47.6% (10/21) in the pancreatic injury subgroup and 16.1% (10/62) of the total patient cohort. Preemptive treatment was administered to 47.6% (10/21) of patients with pancreatitis, the effective rate was 100%. Among these patients, 70% (7/10) underwent successful rechallenge with ICIs. The occurrence of pancreatic injury was positively correlated with the treatment duration (P < 0.05) but showed no significant correlation with combination therapies (P > 0.05).
Conclusion: The likelihood of pancreatic injury increased with longer treatment durations with ICIs; no significant association was found between the incidence of ICIs-related pancreatic damage and combination therapies. Preemptive treatment for immune-related pancreatitis is feasible, allowing some patients to successfully undergo rechallenge with ICIs therapy.

Background: Lung ischemia-reperfusion injury (LIRI) is a pathological condition characterized by aggravated oxidative-inflammatory tissue damage that occurs upon blood flow restoration after ischemia. LIRI can lead to severe complications, including primary graft dysfunction in lung transplants and multi-organ failure. However, current treatments remain limited.

The characteristic pathological change in chronic pancreatitis (CP) is pancreatic fibrosis. In the early stages of CP development, injured acinar cells induce the infiltration of inflammatory cells, followed by pancreatic stellate cell (PSC) activation. Activated PSC induce the deposition of extracellular matrix (ECM) and promote the development of pancreatic fibrosis.

Cadmium (Cad) is a worldwide heavy metal pollutant associated with global health challenges. Alteration of the intestinal microbiome, due to chemicals' exposure, plays a vital role in the pathogenesis of gastrointestinal diseases such as pancreatic disorders. Hence, modulation of the gut microbiota might be a targeted approach to manage pancreatic diseases.

Ethnopharmacological Relevance: Liquorice (Gancao), a classic Chinese herb, has been historically prescribed for inflammation and gastrointestinal disorders. Its bioactive flavonoid liquiritigenin (4',7-dihydroxyflavone) exhibits anti-inflammatory properties, yet its efficacy against acute pancreatitis (AP) remains unexplored.
Aim: To systematically investigate the therapeutic potential of liquiritigenin against AP and decipher its estrogen receptor beta (ERβ)-mediated mitochondrial regulatory mechanisms.
Background: Triggering receptor expressed on myeloid cells 1 (TREM-1), an inflammation amplifier, is an emerging target in inflammation and oncology.
Objective: To test my hypothesis that pan-TREM-1 and macrophage-restricted TREM-1 blockades may differ in their efficacy in cancer and other inflammatory diseases.
Methods: Ligand-independent TREM-1 inhibitory peptides GF9 and GA31 (the latter in a form of macrophage-targeted lipopeptide complexes, GA31-LPC) were used as pan-TREM-1 and macrophage-restricted TREM-1 inhibitors, respectively, to test the hypothesis in multiple animal models of cancer, sepsis, pulmonary inflammation and fibrosis.
