Expressions of ?-smooth muscle actin and collagen type Ⅰ,Ⅲ in biopsy liver tissue from patients with fibrosing cholestatic hepatitis / 中国医师进修杂志

Objective To observe expressions of ?-smooth muscle actin(?-SMA) and collagen type Ⅰ,Ⅲ deposition in the liver tissues, and to evaluate potential mechanism of fibrosis in patients with fibrosing cholestatic hepatitis (FCH) by collagen synthesis. Method Immunohistochemical staining was used to detect the expressions of ?-SMA and contents of type Ⅰ,Ⅲ collagen proteins, which were from the specimens of the biopsy liver in 9 cases with FCH associated with hepatitis virus B (HBV) developed following renal transplantation and in 5 cases without liver disease(control group), respectively. Results The expressions of ?-SMA and type Ⅰ,Ⅲ collagen proteins in the patients with FCH were significantly higher than those in the control group. The expression and distribution pattern of ?-SMA and type Ⅰ,Ⅲ collagen proteins were almost identical, and quantitative analysis showed a positive correlation (P

Relationship Between Plasma Prothrombin Activity and Histology of the Liver in Patients with Viral Hepatitis / 中国医师杂志

Objective To explore the relationship between plasma prothrombin activity (PTA) and histopathological lesion of the liver in patients with viral hepatitis. Methods A retrospective review of plasma PTA level and hepatohistological grading was performed in 234 patients with chronic hepatitis B (CHB) and 54 patients with severe hepatitis diagnosed both clinically and pathologically. Results PTA level was obviously negatively correlated with the hepatohistological Ishak score (P
