Objective To study vascular anatomy between the pancreatic head and duodenum,providing anatomy basis for performing surgery of pancreatic head,duodenum and distal common bile duct in surgical practice. Methods Anatomy study was performed in 30 formaldehyde fixed and 10 fresh bodies in reference to blood supply to duodenum,the distal common bile and Vater ampulla. Results The anterior and posterior pancreaticoduodenal arterial arcade gives off branches to descending and horizontal portion of the duodenum. The posterior superior pancreaticoduodenal artery goes to distal common bile duct. The papilla artery arising from the posterior superior pancreaticoduodenal artery goes to Vater ampulla. Conclusions The pancreaticoduodenal anterior and posterior arterial arcades are main arteries that give off branches to the descending and horizontal portion of the duodenum,distal common bile duct and the Vater ampulla,hence should be carefully protected in duodenum-preserving resection of the pancreatic head.

Objective To investigate the protective effects of ShenFu injection on kidney of experimental acute pancreatitis in mrs. Methods Twenty and one Wister rats were randomized into the sham-operated group,AP group and Shenfu group. The plasma level of MDA,MPO,SOD,TNF-α and the kidney level of MDA、ON、SOD and historical scores was determined. Results The values of plasma SOD、MDA、MPO、TNF-α and the kidney of MDA、ON and historical scores in Shenfu-gronp were higher than that in the sham-operated group but lower than that in AP group. The values of SOD of plasma and kidney in Shenfu group is higher than that in AP but lower than that in the sharm-operated group. Coneluion Shenfu injection can protect the early injure of kidney of severe acute panereatitis,which mechanism may be to improve the kidney microcirculation,to reduce the production of TNF-α,to decrease the inflammation of plasma and kidney and to decrease the injure of oxygen free radicals.
