Acute pancreatitis (AP) presenting as an acute abdomen is a common clinical condition. Acute inflammation causes varying degrees of necrosis of the pancreatic tissue. As the disease progresses, the pathological changes of pancreatic tissue also take a dynamic process. Pancreatic tissue repair is important for recovery of the function of the pancreas after AP. So investigations of the mechanism for pancreatic repair may provide theoretical help for the clinical therapy of AP.
