Hepatitis B virus (HBV) infection is an important public health concern, as approximately 3.5% of the world's population is currently chronically infected. Chronic HBV infection is the primary cause of cirrhosis, hepatocellular carcinoma, and deaths related to liver disease globally. Studies have found that in HBV infection, viruses can directly or indirectly regulate mitochondrial energy metabolism, oxidative stress, respiratory chain metabolites, and autophagy, thereby altering macrophage activation status, differentiation types, and related cytokine secretion type and quantity regulations. Therefore, mitochondria have become an important signal source for macrophages to participate in the body's immune system during HBV infection, providing a basis for mitochondria to be considered as a potential therapeutic target for chronic hepatitis B.

<b>OBJECTIVEb>To compare the clinical values of the model for end-stage liver disease (MELD)-Na scoring system and the Child-Turcotte-Pugh (CTP) scoring system for predicting the short-term prognosis of acute-on-chronic hepatitis B liver failure.

<b>METHODSb>A total of 339 patients with acute-on-chronic hepatitis B liver failure and admitted to the Eighth People's Hospital of Guangzhou and Nanfang Hospital of Southern Medical University between January 2010 and December 2012 were included in this retrospective analysis. The short-term predictive values of MELD-Na and CTP scores were compared for this patient population.

<b>RESULTSb>The mean MELD-Na score in the advanced stage of liver failure was significantly higher than those in the early and middle stages, respectively (both P less than 0.01). The mean MELD-Na score in the middle stage of liver failure was also significantly higher than that in the early stage (P less than 0.01). In contrast, the mean CTP scores for the three stages of liver failure were not significantly different (all P more than 0.05). The MELD-Na score showed a stronger correlation with the stage of liver failure (rs =0.485, P less than 0.01) than did the CTP score (rs =0.306, P less than 0.01). The short-term mortality rates were significantly different for the three stages of liver failure (P less than 0.01). The mean MELD-Na score of the death group was significantly higher than that of the survival group (P less than 0.01). The CTP scores, however, were not significantly different between the death and survival groups (P more than 0.05).The short-term mortality rate of liver failure was significantly higher for patients with increased scores for the MELD-Na and CTP systems (both P less than 0.01). The areas under the curve of the MELD-Na and CTP scores were 0.813 and 0.823, respectively. The MELD-Na and CTP score have similar predictive values (P more than 0.05).

<b>CONCLUSIONb>The MELD-Na scoring system is slightly superior to the CTP scoring system for predicting short-term prognosis of acute-on-chronic hepatitis B liver failure.The predictive value may improve for both the MELD-Na score and the CTP score when combined with expert clinical practice and experience.

Management of chronic hepatitis B virus (HBV) infection during pregnancy remains a challenging task. This review summaries the impact of HBV infection on both mothers and babies,the risks and benefits of various antiviral therapies during pregnancy, the patient and drug selection,and the management during follow-up.

The pathogenesis of hepatitis B virus （HBV）-associated hepatocellular carcinoma （HCC） is complicated with the crosstalk of multiple factors and the multi-step processes. The main mechanisms underlying the HBV-induced HCC include:①integration of HBV DNA into the host hepatocyte genome to alter gene function at the insertion site，resulting in host genome instability and expression of carcinogenic truncated proteins;②HBV gene mutations at S，C，and X coding regions in the genome;③HBV X gene-encoded HBx protein activates proto-oncogenes and inhibits tumor suppressor genes，leading to the HCC occurrence. In this article，the recent research progress on the molecular mechanism of HBV-induced HCC is comprehensively reviewed，so as to provide insights into the prevention，early prediction and postoperative adjuvant therapy of HCC.
