A total of 437 patients with hepatitis B were tested for serum HBxAg and anti-HBx in a seroepidemiological study. It was shown that the HBxAg positivity rate was 3.66% (16/437), the anti-HBx positivity rate was 2.97% (13/437). HBxAg was most frequently present in HBsAg, HBeAg, and anti-HBc positive, but anti-HBe negative sera. Anti-HBx was most frequently present in HBeAg and anti-HBc positive, but HBsAg and anti-HBe negative sera. Both the presence of HBxAg and anti-HBx antibodies showed no significant relationship with the presence of serum anti-HBs antibodies. These results indicated that serum HBxAg/anti-HBx system was related to the replications of HBV in the HBV infected human body, and anti-HBx were not protective antibody.

D006509	Hepatitis B	INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.

D054334	Viral Regulatory and Accessory Proteins	A broad category of viral proteins that play indirect roles in the biological processes and activities of viruses. Included here are proteins that either regulate the expression of viral genes or are involved in modifying host cell functions. Many of the proteins in this category serve multiple functions.
