Abstract： Objective To compare the treatment effects of Qingyi Huoxue decoction and infliximab on acute necrosis pancreatitis ( ANP) complicated with MODS in a rat model. Methods 4.5% sodium taurocholate was injected into the pancreatic duct to induce the ANP complicated with MODS model. The ANP rats were randomly divided into 3 groups, ANP group (ANP), Qingyi Huoxue decoction treatment group ( QG) , infliximab treatment group (IG). Rats in infliximab group received infliximab injection at a dose of 8 mg/kg body weight via tail vein 6 h after the ANP induction. The ANP and QG received normal saline and Qingyi Huoxue decoction (20 ml/kg) via gastric lavage 4 h before and 3 h, 9 h after ANP induction. After 24 h, all rats were sacrificed, the serum levels of amylase, total bilirubin, Cr, TNF-α, diamine oxidase ( DAO) , intra-abdominal pressure (IAP) and the rate of carbon propelling rate in ileum were measured. The pancreas samples were collected for pathological examination. The pathological score of pancreas was calculated. Results The pathological scores in ANP, QG, IG were 13.8 ±0.8, 6.1 ±0.4, 3.9 ±0.6, and the difference was statistically significant (P <0.05). The serum levels of amylase, total bilirubin, Cr, TNF-α were significantly decreased. In ANP, QG, IG the serum levels of DAO were (186.3 ± 10.2 ) , ( 134.6 ± 14.3 ) , ( 149.1 ± 16.3) U/L; the carbon propelling rates in ileum were (53 ±0.1)% , (89 ±0.1)% , (61 ±0.1)% ; the IAPs were (11.8 ±1.5), (4.1±0.8), (5.8 ±1.2) mmHg(1 mmHg=0.133 kPa). The DAO and IAP in AG, IG were significantly decreased when compared with that in ANP group, but the carbon propelling rates in ileum was significantly higher than that in ANP group, and the difference was statistically significant ( P < 0.05). In addition, the carbon propelling rates in ileum in QG were higher than that in IG, and IAP and DAO levels were lower than that in IG, and the difference was statistically significant (P <0.05). Conclusions The Qingyi Huoxue decoction and infliximab were significantly effective in the treatment of ANP rats complicated with MODS. But the effects of Qinyi Huoxue decoction on promoting gastrointestinal motility, reducing the IAP and improving the intestinal barrier function were better than those of the infliximab.
