[Expression of secretory type II phospholipase A₂ in acute lung injury following acute pancreatitis and interventional effect of Qingyi decoction on it].

Objective: To investigate the expression of secretory type II phospholipase A(2) (sPLA(2)-II) in lung of rats with acute lung injury (ALI) complicating severe acute pancreatitis (SAP), and the effect of Qingyi decoction (QYT) on ALI.

Methods: Thirty Sprague Dawley (SD) rats were randomly divided into three groups: sham operation (SO) group, model group and QYT group, with 10 rats in each group. SAP model was reproduced by reverse injection of sodium deoxycholate into the common bile- pancreatic duct of rats.
