Knockout or treatment with an antagonist of formyl peptide receptor 1 protects mice from sepsis by inhibiting inflammation.
Cytokine

Department of Gastroenterology, General Hospital of Ningxia Medical University (The First Clinical Medical College of Ningxia Medical University), 750004 Yinchuan, China.
Background: Sepsis is an infection-related systemic inflammation with high mortality rates. Activation of formyl peptide receptor 1 (FPR1) in immune cells can promote their chemotaxis and inflammatory response, which imbalances immune response during the process of sepsis. FPR1 blockade did diminish systemic inflammatory response during bacterial infection.

Materials And Methods: This retrospective study included 109 patients who underwent US-guided omental biopsies between June 2020 and June 2024. Pre-biopsy diagnostic images (CT, MRI, or [18 F]FDG PET/CT) were reviewed.

Gastric cancer (GC) is the third leading cause of cancer-related deaths worldwide, with gastrectomy being the primary treatment option. Sepsis, a systemic inflammatory response to infection, may influence tumor growth by creating an immunosuppressive environment conducive to cancer cell proliferation and metastasis. Here, the effect of abdominal infection on tumor growth and metastasis was investigated through the implementation of a peritoneal metastasis model and a subcutaneous tumor model.

Medicine (Baltimore)
January 2025
Department of General Surgery, Nujiang Prefecture People's Hospital, Yunnan, Nujiang, China.
Rationale: Peritoneal mucinous cystadenoma is rare in the clinic, lacks specific clinical manifestations, tumor markers, and imaging features, and is easily misdiagnosed and missed. Clinical practitioners should maintain a high level of vigilance. Here, we report a case of laparoscopic peritoneal mucinous cystadenoma stripping to improve our understanding of the disease.
