The anatomical features of dorsal pancreatic artery in the pancreatic head and its clinical significance in laparoscopic pancreatoduodenectomy.

Background: Bleeding control as one of the major challenges in laparoscopic pancreaticoduodenectomy (LPD) necessitates a considerable anatomical knowledge of the blood supply to the pancreatic head so as to improve the safety of this surgery. This study aimed towards a better understanding of the anatomical features of the dorsal pancreatic artery (DPA), as well as its clinical significance in LPD.

Method: Thirteen Chinese cadaveric specimens were used to study the blood supply of the pancreatic head.

Early repolarization pattern in the general population: Prevalence and associated factors.

Objectives: To evaluate the prevalence of early repolarization pattern (ERP) in the general rural Chinese population and identify the contributing risk factors.

Methods: A cross-sectional study of 11,956 permanent residents of Liaoning Province ≥35y of age was conducted between January and August 2013 (response rate 85.3%).
