[Effects of miR-122 on expression of hepatitis B virus proteins].

Objective: To investigate the effect of miR-122 on the expression of hepatitis B virus (HBV) proteins.

Methods: Anti-sense oligodeoxynucleotide (ASODN) of two different sequences against miR-122, anti-miR-122 and LNA-antimiR-122 (Locked nucleic acid), human miR -122 (hsa-miR-122), or the negative control anti-GFP were designed and synthesized, then transfected into HepG2.2.

Surveillance of viral contamination of invasive medical instruments in dentistry.

Objective: To investigate the viral contamination of invasive medical instruments in dentistry and to provide health administrative institutions with surveillance data.

Methods: Sterilized samples were randomly collected from the department of dentistry to detect HBV-DNA, HCV-RNA, HIV-RNA and HBsAg.

Results: Of the invasive medical instruments that were sterilized with 2% glutaraldehyde, one of the samples was positive for HBV-DNA, and another sample was positive for HBsAg.

[Inhibition of hepatitis B virus S gene and C gene expression by different 10-23 DNAzymes substrate-recognition domains].

Objective: To explore the inhibition effects of 10-23 DNAzymes with different substrate-recognition domains targeting hepatitis B virus (HBV) S gene and C gene expression in 2.2.15 cells.

Association of cytomegalovirus infection with human leukocyte antigen genotypes in recipients after allogeneic liver transplantation.

Background: Cytomegalovirus (CMV) infection is the important cause affecting the survival rate and function of the transplanted organ after transplantation. The occurrence of CMV infection after liver transplantation (LT) is associated with many factors. Lots of studies suggest that genetic mutation between hosts and CMV may play a role in the occurrence and development of CMV infection.
