Abstract:Objective To investigate the effectiveness of Xuebijing combined with ulinastatin and octreotide in the treatment of severe acute pancreatitis (SAP), and to study its influence on inflammatory indicators.Methods From October 2021 to August 2024, 60 cases of SAP who treated in the 908th Hospital of the Joint Service Support Force of the Chinese People's Liberation Army were divided into two groups, with 30 cases in each group, using a random number table method. The patients in the control group took ulinastatin and octreotide, and the patients in the observation group added Xuebijing, both groups received continuous treatment for 10 days. The comparisons were performed on the clinical efficacy, inflammatory indicators, degree of intestinal mucosal injury, immune function and adverse reactions in both groups.Results The total effective rate of the observation group (93.33%) was higher than that of the control group (73.33%). After treatment, tumor necrosis factor-α (TNF α) (20.53±1.55) pg/mL, procalcitonin (PCT) (3.42±0.53) mg/L, C-reactive protein (CRP) (43.55±2.76) mg/L, interleukin-6 (IL-6) (35.75±2.46) pg/mL were lower than those of the control group. D-lactic acid and serum endotoxin were lower than those of the control group. CD3+ and CD4+ were higher than those of the control group. CD8+ was lower than that of the control group.The difference was statistically significant (P<0.05); There was no significant difference in adverse reactions between the two groups (P>0.05).Conclusion Xuebijing combined with ulinastatin and octreotide in the treatment of SAP patients can effectively reduce the inflammatory reaction and intestinal mucosal damage, and improve immune function, which is safe and reliable.
