The clinical significance of a myetoperoxidase (MPO) gene polymorphism and inducible nitric oxide synthase (iNOS) expression in cirrhotic patients with hepatopulmonary syndrome (HPS) was explored. Enrolled subjects were divided into three groups according to their disease/health conditions: the HPS group (cirrhotic patients with HPS;n=63), the non-HPS group (cirrhotic patients without HPS;n=182), and the control group (healthy subjects without liver disease;n=35). The distribution of the MPO -463 G/A genotype and its relationship with iNOS expression in a typical cell block from as-citic fluid were detected by immunohistochemistry and polymerase chain reaction-restricted fragment length polymorphism analysis (PCR-RFLP). In the HPS group, the partial pressure of oxygen in blood and ascitic fluid was significantly decreased (8.95±1.58 kPa and 6.81±0.95 kPa, respectively;both P
