Collect basic information of patients before antiviral treatment and when HBsAg disappears, and divide them into three groups A, B, and C based on baseline anti HBs titers after informed consent. During the follow-up period of all patients, clinical biochemistry, virology (HBVDNA, HBVRNA), serological indicators (HBsAg, anti HBs, HBeAg, anti HBe, HBcrAg, anti HBc), AFP, Fibroscan, liver imaging examinations will be conducted every 3-6 months, and blood samples will be retained for monitoring the frequency of immune cells (pDC, Treg) and the expression of functional molecules, as well as cytokines (IFN - γ, IP-10, IL-10, and TGF - β). Observe the sustained response rate and recurrence rate of virological and serological indicators, as well as the incidence of hepatitis and liver cancer during the follow-up period.
Collect basic information of patients before antiviral treatment and when HBsAg disappears, and divide them into three groups A, B, and C based on baseline anti HBs titers after informed consent. Group A has an anti HBs titer ≥ 100mIU/ml and is followed up every 3-6 months for observation. The anti HBs titers\<100mIU/ml were randomly divided into two groups: Group B and Group C. Group B did not intervene and was followed up every 3-6 months for observation; In group C, 20 micrograms of recombinant hepatitis B vaccine were injected subcutaneously three times on day 0, January and March. For group C patients, the level of anti HBs was detected at the 4th month after the initial vaccination. For those who could not produce anti HBs (anti HBs\<10mIU/ml), the recombinant hepatitis B vaccine was subcutaneously injected three times, 20 μ g each time, in 0 day, January and March. During the follow-up period of all patients, clinical biochemistry, virology (HBVDNA, HBVRNA), serological indicators (HBsAg, anti HBs, HBeAg, anti HBe, HBcrAg, anti HBc), AFP, Fibroscan, liver imaging examinations were conducted every 3-6 months, and blood samples were retained for monitoring the frequency of immune cells (pDC, Treg) and the expression of functional molecules, as well as cytokines (IFN - γ, IP-10, IL-10, and TGF - β). Observe the sustained response rate and recurrence rate of virological and serological indicators, as well as the incidence of hepatitis and liver cancer during the follow-up period.

RECRUITINGSustained response rate and relapse rate by virological and serological indicators
The levels of biochemical, AFP, HBV DNA, HBV RNA, HBsAg, anti-HBs, HBeAg, anti-He, anti-He, HBcrAg and anti-HBc measured the expression of frequency and functional molecules of peripheral blood pDC and Treg cells and the plasma levels of IFN- γ, IP-10, IL-10 and TGF- β
Time frame: Conduct testing every 3-6 months
The incidence of hepatitis and liver cancer
The incidence of hepatitis and liver cancer among the enrolled researchers during the research process The incidence of hepatitis and liver cancer among the enrolled researchers during the research process The incidence of hepatitis and liver cancer among the enrolled researchers during the research process.
Time frame: 36 months
