ABSTRACT
Objective To investigate hepatic pathohistological changes(including pathology,HBV markers in liver tissue)in patients with KBeAg negative chronic hepatitis B after adefovir therapy for 1 year.Methods 35 patients with HBeAg negative chronic hepatitis B were administered with 10mg adefovir once a day for one year.The needle biopsy of liver were performed before and after treatment.The routine HE stained liver tissue sections were evaluated and Knodell pathological score were done.HBsAg and HBeAg in liver tissue were examined by immunohisochemisty method.Results After 1 year,18,17 and 11 cases had a significant reduction of their total hepatic HAI score,necroinflammation and fibrosis score.The immunohistochemistry examination showed HBeAg in liver decreased significantly,but HBsAg had no obvious alteration.Conclusion Significant improvement in both necroin flammation and fibrosis can be obtained in the majority of patients treated with adefovir for 1 year.More significant improvement in live histology can be obtained after extended treatment.
ABSTRACT
Objective To investigate the endoscopic prevalence of erosive esophagitis (EE) among 13 hospitals in Guangdong province of China. Methods Retrospectively reviewed all the cases (63459 cases) that received oesophagogastrodeuodenoscopy in 13 main hospitals in Guangdong province of China in 2003. Los Angeles criteria for classification of erosive esophagitis were employed as the basis of analysis. Results One thousand two hundreds and sixty-three patients (age range 3-90yr, mean 50. 2 ?17. 1 ) were found to have EE. The overall prevalence of EE was 1. 99% (1263/63459). The prevalence of EE in A, B, C, and D grade were 0. 94% , 0. 69% , 0. 21% and 0. 14% respectively. Age correlated positively on endoscopic grading of EE (F=22. 932, P
