Objectives To investigate the synergistic activity of infliximab to the therapeutic effectiveness of octreotide in a rat model of acute necrotizing pancreatitis (ANP). Methods: Forty Sprague-Dawley rats were randomly divided into sham-operated group (SO), ANP group (ANP), octreotide group (OG), infliximab group (IG), and combination group (CG) (n = 8 in each group). The ANP model was induced by biliopancreatic duct injection with 4.5% of sodium taurocholate solution. Rats of the OG, IG, and CG were given a tail vein injection of octreotide (10 μg/kg), infliximab (8 mg/kg), and infliximab (8 mg/kg), respectively, combined with octreotide (10 μg/kg) at 6 hours after modeling. All rats in each group were killed at 24 hours after modeling. Serum biochemical indicator and partial pressure of arterial oxygen/fraction of inspired oxygen (PaO2/FiO2) of rats were determined. Pathological severity score of organs were evaluated. Results: The serum biochemical indicator and organs' pathology score of OG , IG, and CG were obviously lower than those in the ANP group, and those in the CG were the lowest (P < 0.05). The PaO2/FiO2 levels in the OG, IG, and CG were significantly higher than that in the ANP group (P < 0.05). Conclusion: Infliximab could significantly lower the serum biochemical indicator, improve organs' function, and enhance the therapeutic effectiveness of octreotide on ANP.
