[Methods]86 cases of acute pancreatitis were randomly divided into the control group( 43 cases) and the treatment group( 43 cases). The control group was given saline enema and routine treatment of western medicine,while the treatment group was treated with Dahuang( Rhubarb) decoction retention enema and routine treatment,2 times/d. After 7 days of treatment,two groups of clinical curative effects were compared. And changes of IL-6,hs-CRP,endotoxin and amylase levels before and after treatment in two groups were compared. [Results] Abdominal pain,abdominal distension,exhaust defecation,bowel sounds in treatment group patients were obviously improved. After treatment,the decline levels of serum IL-6,hsCRP,endotoxin and amylase in the treatment group were significantly better than those in the control group. [Conclusions] Dahuang( Rhubarb) retention enema can significantly improve the clinical curative effect of severe acute pancreatitis,and its mechanism may be related to the inhibition of inflammatory reaction.展开更多
