大承氣湯治療重癥急性胰腺炎腸功能障礙的機(jī)制研究
[Abstract]:Objective: to explore the possible mechanism of Dachengqi decoction in the treatment of (SAP) intestinal dysfunction in rats with severe acute pancreatitis. Methods: Fifty-four male SD rats were randomly divided into sham-operated group (SO group), severe acute pancreatitis group (SAP group) and Dachengqi decoction group (18 rats in each group). The model of intestinal dysfunction of SAP was established by injecting 3.5% sodium taurocholate 0.1 mL / 100g body mass into the biliary and pancreatic duct. The treatment group was given 10% Dachengqi decoction (9.18 g/kg body mass) once a time before making the model. SAP group and SO group were perfused with 0.9% sodium chloride solution. In each group, 6 rats were killed in each group for 12 hours, and blood was taken from the heart. Serum amylase and lipase levels were measured. Serum 5-hydroxytryptamine (5-HT) and interleukin-6 (IL-6) levels were measured by enzyme-linked immunosorbent assay (Elisa). At the same time, the expression of 5-HT7R in jejunum, terminal ileum and sigmoid colon was detected at 6 h. Results: the levels of serum amylase, lipase and 5-HT in SAP group and treatment group were significantly higher than those in SO group (P0.05), and the levels of serum amylase, lipase and 5-HT in treatment group were significantly lower than those in SAP group at each time point (P0.05). Compared with SO group, the expression of 5-HT7R protein and positive cell area in SAP group were significantly higher in jejunum, terminal ileum and sigmoid colon (P0.05). Compared with SAP group, 5-HT7R protein and positive cell area in treatment group were decreased (P0.05). Conclusion: the increase of serum 5-HT and excessive activation of 5-HT7R may be one of the causes of intestinal dysfunction in SAP, while Dachengqi decoction may promote the recovery of intestinal function by reducing the expression of 5-HT7R.
