Platycodon grandiflorus polysaccharide (PGP) is one of the main components of P. grandiflorus, but the mechanism of its anti-inflammatory effect has not been fully elucidated. The aim of this study was to evaluate the therapeutic effect of PGP on mice with dextran sodium sulfate (DSS)-induced ulcerative colitis (UC) and explore the underlying mechanisms. The results showed that PGP treatment inhibited the weight loss of DSS-induced UC mice, increased colon length, and reduced DAI, spleen index, and pathological damage within the colon. PGP also reduced the levels of pro-inflammatory cytokines and inhibited the enhancement of oxidative stress and MPO activity. Meanwhile, PGP restored the levels of Th1, Th2, Th17, and Treg cell-related cytokines and transcription factors in the colon to regulate colonic immunity. Further studies revealed that PGP regulated the balance of colonic immune cells through mesenteric lymphatic circulation. Taken together, PGP exerts anti-inflammatory and anti-oxidant effect and regulates colonic immunity to attenuate DSS-induced UC through mesenteric lymphatic circulation.

It is helpful for diagnostic purposes to improve our current knowledge of gut development and serum biochemistry in young piglets. This study investigated serum biochemistry, and gut site-specific patterns of short-chain fatty acids (SCFA) and expression of genes related to barrier function, innate immune response, antioxidative status and sensing of fatty and bile acids in suckling and newly weaned piglets. The experiment consisted of two replicate batches with 10 litters each.

Choroidal metastasis from occult cutaneous melanoma is rare and can masquerade as ocular inflammation. A 70‑year‑old man with sectoral anterior scleritis was found on multimodal imaging to have a solitary choroidal mass with mild periscleral fluid, prompting systemic evaluation that uncovered colonic polyps that, on histopathology, contained metastatic melanoma, a scalp primary, and widespread visceral, nodal, and intracranial metastases. Tumour cells stained HMB‑45, Melan‑A, and SOX10 positive, AE1/AE3 negative, and carried an NRAS‑Q61 mutation with wild‑type BRAF, confirming cutaneous origin.

Objective: Anesthesia during the surgery impairs immune systems. Ketamine is an anesthetic with immune protective effects. This study intended to investigate the effect of a ketamine-involved anesthetic regimen on cellular immunity and inflammatory cytokines in patients who undergo laparoscopic colon cancer surgery.

Objectives: Proteasomes, multi-subunit proteases, are key actors of cellular protein catabolism and a number of regulatory processes. The detection of subtle proteasome functioning in tumors may contribute to our understanding of the mechanisms of cancer development. The current study aimed to identify the role of low molecular mass protein 2 (LMP2), a proteasome immune subunit, in the development of mouse colon 26 (C26) adenocarcinoma.

Background And Objective: CD68 plays a crucial role in promoting phagocytosis. However, its expression level, prognostic value and the correlations with tumor-infiltrating immune cells (TIICs) or common tumor immune checkpoints (TICs) in human digestive system cancers (DSC) remain poorly understood. This study aims to investigate the expression levels, prognostic significance, and clinical implications of CD68, as well as its correlations with six TIICs and four common TICs in DSC.
