[Occult hepatitis B virus infection in chronic viral hepatitis patients with non-A to E hepatitis virus infection].

Objective: To observe the status of occult hepatitis B virus infection in chronic viral hepatitis patients with non-A to E hepatitis virus infection and explore the diagnostic value of fluorescence quantitative polymerase chain reaction (FQ-PCR) technique for occult hepatitis B virus infection.

Methods: The amount of HBV-DNA in serum and liver tissue from 57 patients with non-A to E hepatitis virus infection who were diagnosed as chronic viral hepatitis by Menghini method liver biopsy were detected by using FQ-PCR technique, then the relation between the viral load of HBV DNA in liver tissue and hepatic inflammatory activity were analyzed.

Results: Thirteen (22.

[Role of hepatitis C virus superinfection in hepatic pathologic changes of patients with chronic hepatitis B: a retrospective short-term and long-term comparative study].

Objective: To observe the effect of hepatitis C virus (HCV) superinfection on the short-term and long-term hepatic pathological changes in patients with chronic hepatitis B (CHB).

Methods: HCV-RNA of twice corresponding period serum samples was detected via reverse transcription polymerase chain reaction assay from 230 patients with CHB for whom liver biopsy was performed at an interval of 0.5-15 years, respectively.
