The target puncture sites on the portal vein branch are either at the portal vein imaging Palbociclib clinical trial bifurcation or beyond. Conclusion: There is an upper-rear and lower-front spatial relationship between the right hepatic vein and the portal vein, and that the distance between the right hepatic vein opening and portal vein bifurcation is, in the vast majority of cases, equal to or greater than one vertebra, providing guidance to the direction and

distance of the TIPS puncture. The location of the right hepatic vein, the location of the portal vein, and the portal vein branches are not correlated with gender, age and Child classification of the patients, and the safe target for portal vein puncture is at the portal vein imaging bifurcation and beyond.

Methods: Patients with clinically diagnosed HBV related cirrhosis who underwent a liver transplantation from 2008 to 2011 were studied. 2.5 x 2.5 cm liver tissue was sectioned. Necrosis, ductualar regeneration, cholestasis and sepsis parameters were evaluated by hematoxylin and eosin, Masson trichrome stains and immunohistochemical staining for CK7. Results: 174 enrolled patients with chronic HBV related cirrhosis were divided into 2 groups, with 69 patients in MHN/SMHN(+) group and 105 patients in MHN/SMHN(–) group. Microscopically, the characteristic features of MHN/SMHN(+) livers were: 1)Massive/submassive necrosis, found in part of cirrhotic nodules, distributed along terminal hepatic veins. The necrotic area was divided into three levels, including less than 1/3, 1/3-2/3 and over 2/3. The percentages

of patients of each level were 17.4%, 66.7%, and 15.9%, respectively. 2)There were obvious periportal ductular regeneration(CK7 positive) and some degree of hepatocytes MCE公司 diffferenciation(so called intermediate hepatocytes). The percentage of patients with ductular regeneration and intermediate hepatocytes in MHN/SMHN (+) group were 78.2% and 62.3%, respectively while those in MHN/SMHN(–) group were only 3.9% and 1.3%, respectively (p < 0.001). 3)Cholestasis in hepatocytes, bile canaliculus and regenetive ductules, were 81.2%, 87% and 92.8% respectively in MHN/SMHN(+) group while only 7.8%, 9.1% and 7.8% in MHN/SMHN(–) group (p < 0.001 respectively).4)The percentage of patients with cholestasis in ductules of cirrhotic nodules, indicating sepsis, was 6.
