Severe acute pancreatitis (SAP) is a severe clinical condition associated with high rates of morbidity and mortality. Multiple organ dysfunction syndrome that follows systemic inflammatory response syndrome is the leading cause of SAP-related death. Since the inflammatory mechanism of SAP remains unclear, there is currently a lack of effective drugs available for its treatment. Therefore, it is important to study effective therapeutic drugs and their molecular mechanisms based on studying the inflammatory mechanism of SAP. In the present study, in vivo, a mouse model of AP induced by cerulein (CR) combined with lipopolysaccharide (LPS) was established to clarify the therapeutic effect of artesunate (AS) in AP mice by observing the gross morphological changes of the pancreas and surrounding tissues, calculating the pancreatic coefficient, and observing the histopathology of the pancreas. The serum amylase activity in AP mice was detected by iodine colorimetry and the superoxide dismutase activity
