Metagenomics is a new approach to study microorganisms obtained from a specific environment by functional gene screening or sequencing analysis. Metagenomics studies focus on microbial diversity, community constitute, genetic and evolutionary relationships, functional activities, and interactions and relationships with the environment. Sequencing technologies have evolved from shotgun sequencing to high-throughput, next-generation sequencing (NGS), and third-generation sequencing (TGS).

This study aimed to investigate the sustainability of HBsAg loss and the prevention of clinical relapse.
Methods: Patients with CHB who achieved HBsAg loss and HBV DNA levels <20 IU/ml after IFN or NUC-IFN therapy were enrolled and followed up for 96 weeks.
Liver necroinflammation is the indicator for treating patients with chronic hepatitis B (CHB) infection. However, there is no suitable non-invasive index for diagnosing liver necroinflammation. This study aimed to create a non-invasive index to predict liver necroinflammation in patients who lack clear-cut clinical inflammation parameters.

However, the durability of HBsAg loss after stopping treatment remains unknown. This study aimed to assess the sustained functional cure achieved by interferon therapy in hepatitis B envelope antigen (HBeAg)-negative CHB patients.

Objective: To explore the effect of intensive treatment for refractory chronic hepatitis C, and to improve the sustained viral response (SVR) rate of treatment with interferon plus ribavirin by optimizing therapeutic dose and course.
Methods: Patients who did not acquire response or partial response by standard therapy (PEG-IFN alpha subcutaneous injection weekly plus Ribavirin 10.5 mg/kg) every day were enrolled and retreated with intensive treatment of 10 MU interferon every other day or 360 microg pegylated interferon alpha-2a weekly according to patients' wishes, and ribavirin 15 mg/kg every day.
