Severe acute pancreatitis (SAP) characterized by atrocious progression and numerous
complications often leads to a high mortality rate due to hypermetabolism, systemic inflammatory
response syndrome (SIRS), and multiple organs dysfunction syndrome (MODS). Studies have
revealed that both early enteral nutrition (EEN) and emodin are potent agents in the management
of SAP. However, whether the combined strategy is rational and more effective than either one
alone remains unknown. In this regard, Wistar rats were treated with emodin-assisted EEN
(EAEEN) through enteral nutrient tubes after induction of SAP by retrograde infusion of 5.0%
sodium taurocholate into the common pancreatic duct. Serum levels of amylase, tumor necrosis
factor-alpha (TNF-α), angiotensin II (AngII), maleic dialdehyde (MDA), glutamic pyruvic
transaminase (ALT), glutamic oxaloacetic transaminase (AST) and C-reactive protein (CRP), intestinal
secretory IgA (SIgA), pancreatic and hepatic myeloperoxidase (MPO) activity as well as plasma levels
of D-lactate and endotoxin were measured. In addition, pathologic alterations of pancreas and liver
were observed microscopically. We found that EAEEN could significantly ameliorate these parameters
and prevent pancreas and liver from serious damage. In conclusion, Our results indicated that EAEEN
could exert beneficial effects on experimental SAP and obviously abate the severity of secondary
hepatic injury. The combined strategy was safe and more effective than either one alone in the acute
stage of SAP. This study also provided an experimental base for the clinical treatment of SAP
patients with EAEEN.
