Effects of interferon on hepatic intercellular adhesion molecule-1 expression in patients with chronic hepatitis B / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the effects of interferon -alpha1b (IFN-alpha1b) on hepatic intercellular adhesion molecule-1 (ICAM-1) expression and serum HBV DNA in patients with chronic hepatitis B.</p><p><b>METHODS</b>Before and 6 months after IFN-alpha1b treatment, liver biopsy was performed in patients with chronic hepatitis B to detect the expression of ICAM-1 in the liver tissues using immunohistochemistry. Serum HBV load was detected with real-time fluorescence polymerase chain reaction.</p><p><b>RESULT</b>CAM-1 expression in the liver tissue was significantly down-regulated after IFN treatment in patients with severe and moderate chronic hepatitis B (P<0.05). No significant variation was noted in the expression of ICAM-1 in the livers of patients with mild chronic hepatitis B after the treatment (P>0.05). In the patients weakly positive for ICAM-1 expression (+), serum HBV DNA varied scarcely after the treatment (P>0.05), while in the patients with strong ICAM-1 positivity (++, +++, or ++++), significant variation of serum HBV DNA occurred after the treatment (P<0.05 or P<0.01).</p><p><b>CONCLUSION</b>The therapeutic effect of IFN-alpha1b is associated with the expression of ICAM-1 in the hepatocytes, and its expression might enhance the effects of IFN on HBV DNA in patients with chronic hepatitis B.</p>

A clinical and pathological study of nonalcoholic fatty liver disease / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study the pathological and clinical features of nonalcoholic fatty liver disease (NAFLD).</p><p><b>METHODS</b>Grades and stages of liver lesions in 41 patients with NAFLD were analyzed. The relationships between pathohistological features of the livers, serum biochemical parameters, ultrasound examination and other clinical data of the patients were studied.</p><p><b>RESULTS</b>Among the 41 patients with NAFLD (there were 21 with their liver fatty degeneration in grade 1, 15 in grade 2, and 5 in grade 3). There were 2 of grade 0, grade 1 had 25, grade 2 had 10, grade 3 had 3, and grade 4 had 1. Stage 0 of fibrosis was 20, stage 1 was 14, stage 2 was 4, stage 3 was 2, and stage 4 was 1. Degree of fatty degeneration was not positively associated with the body mass index (BMI) of the patients and the ultrasound findings in their livers. Grading of the inflammation was positively related to the alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in the blood and ultrasound findings in their livers, but negatively to the platelet counts. Staging of fibrosis of the livers was positively related to the blood ALT, AST, GGT, and ALP, and negatively to triglyceride levels and platelet counts.</p><p><b>CONCLUSIONS</b>Degree of liver fatty degeneration was not associated with grades of inflammation and staging of fibrosis of the liver. BMI, ALT and AST level, platelet counts, and ultrasound grades of fatty liver were associated with the liver histopathological changes of NAFLD patients. Liver biopsy is the essential way to make a diagnosis of NAFLD.</p>
