Objective: To explore the magnetic resonance imaging (MRI) features and classification of intraductal papillary neoplasm of the bile duct (IPNB). Methods: Data from 90 patients with intraductal papillary neoplasm of the bile duct confirmed pathologically between June 2010 and January 2023 were retrospectively analyzed. The image analysis included the shape and location of the tumor, whether bile ducts had dilatation and the degree of dilation, whether there was a history of liver disease, whether there was a history of schistosomiasis, whether there was cancerous transformation, whether there were concurrent bile duct stones, whether there was hepatic lobe atrophy, whether there was hilar or abdominal lymph node enlargement, whether there was invasion of the bile duct wall, whether there was invasion of surrounding blood vessels, whether the tumor appears on T1-and T2 weighted imaging (T(1)WI and T(2)WI), whether the diffusion was limited, whether there was concurrent bleeding, enhancement rate, and whether there was abdominal fluid accumulation. Intraductal papillary neoplasms of the bile duct were divided into four types according to the morphological classification standards: type I (local bile duct dilation), type II (cystic), type III (free tumor), and type IV (dilated bile duct). The differences in the clinical and MRI features of the four groups of lesions were analyzed. Statistical analysis was performed with a t-test, an analysis of variance, and an χ(2)-test according to the different data. Results: Among the 90 cases with hepatic IPNB, there were 31 cases of type I, 15 cases of type II, 16 cases of type III, and 28 cases of type IV, 41 cases of liver left lobe, 11 cases of right and left lobe liver span, 7 cases of liver right lobes, 2 cases of liver caudate lobe, and 13 cases of hepatic hilar. There were statistically significant differences between the four groups (P < 0.05) in terms of age, clinical symptoms, direct bilirubin, γ-glutamyltransferase, whether they were cancerous, whether they were combined with bile duct stones, whether the liver lobes were atrophying, whether there was limited diffusion, intrahepatic bile duct diameter, and common bile duct diameter. However, there were no statistically significant differences among the four groups in gender, location, carbohydrate antigen 19-9, history of liver disease, history of schistosomiasis, carcinoembryonic antigen, alanine aminotransferase, aspartate aminotransferase, total bilirubin, whether hemorrhage was associated, lesion enhancement rate, whether the hilar/retroperitoneal lymph node was enlarged, whether the bile duct wall was invaded, whether blood vessels were invaded, and whether abdominal fluid was accumulated (P > 0.05). Conclusion: MRI manifestations have certain features for different types of intraductal papillary neoplasm of the bile duct tumors; hence, MRI aids in the diagnosis and differential diag

Hepatitis B is mostly a chronic, progressive disease that, if not treated promptly and effectively, can slowly progress to cirrhosis, liver failure, or hepatocellular carcinoma. Therefore, antiviral therapy, i.e., a "complete therapy" strategy, should be started as long as the virus is positive. Immediate antiviral treatment is not recommended for infected patients who are only in the immune-tolerant phase, mainly because of the milder conditions and poor antiviral therapy efficacy, according to antiviral indications in China's Guidelines for the Prevention and Treatment of Chronic Hepatitis B (2022 Version). The relevant issues of why hepatitis B virus infection in the immune-tolerant phase is the last mile of "complete therapy," with an emphasis on the disease's characteristics and antiviral treatment strategies, are discussed here.

Hepatitis B is a major infectious disease that seriously endangers the health of the people of China. Patients with hepatitis B have a large base in our country, and the core indicators such as detection and antiviral treatment ratio are far from the real goal of eliminating the public health threat of uiral hepatitis.Notably, the chronic hepatitis B prevention and control system lacks a wide targeted strategies. This paper systematically analyzes our country's main successful experience with AIDS prevention and control and, on that basis, proposes the ideas and strategic paths for the construction of a chronic hepatitis B prevention and control system, analyzes and discusses the current difficulties and problems in prevention and control, and looks forward to future prevention and control efforts.

Objective: To analyze hepatitis B serologic tests and the current prevalence of hepatitis B virus (HBV) infection among pregnant and postpartum women in China from 2021 to 2023. Methods: Data on managing the prevention of mother-to-child transmission of HIV, syphilis, and hepatitis were retrieved from the National Information System. A positive serum HBsAg test was used to define HBV infection. The χ(2) test was used to compare the coverage rate of the hepatitis B serologic test across different years, in early-stage pregnancy, and the current HBV infection in pregnant and postpartum women. A two-sided P value of <0.05 was considered a statistically significant difference. Results: The coverage rate for hepatitis B serological detection in pregnant (including intrapartum) and postpartum women and early-stage pregnancy rose from 99.68% (10 463 059/10 496 883) and 82.96% (8 707 765/10 496 883) to 99.94% (8 678 777/8 684 387, P < 0.001) and 88.87% (7 717 857/8 684 387, P < 0.001) in China between 2021 and 2023. The current prevalence rate of HBV infection decreased from 4.98% (521 479/10 463 059) in 2021 to 4.56% (396 148/8 678 777) in 2023 among pregnant and postpartum women (P < 0.001). The current prevalence rate of HBV infection ranged from 1.53% to 10.39% among pregnant and postpartum women in various provinces of China in 2023. Conclusion: The coverage rate for hepatitis B serologic tests in China increased significantly between 2021 and 2023 in pregnant and postpartum women. Therefore, the current prevalence rate of HBV infection has decreased significantly in pregnant and postpartum women, but a regional difference still exists.

The global chronic hepatitis B (CHB) guidelines have gradually expanded treatment indications in order to accelerate the elimination and improve the treatment rate of hepatitis B virus (HBV) infection. This article analyzes the new treatment concepts for chronic hepatitis B at home and abroad from two aspects: expanding treatment by paying more attention to the long-term prognosis of the disease and maximizing the use of existing drugs in order to achieve the early goal of the World Health Organization's of eliminating viral hepatitis by 2030.

The previous treatment criteria for chronic hepatitis B were based on the risk of complications occurring. International guidelines recommended treating only high-risk patients who developed complications, which was called the "treat only if..." strategy. Later, it was found that 33.5%~64.0% of the cases that developed hepatocellular carcinoma (HCC) did not meet the treatment criteria of international guidelines, suggesting that the treatment criteria for chronic hepatitis B need to be expanded. Following this, the "treat only if..." strategy was replaced by the "treat all except..." strategy. The latter is to treat all except patients at very low risk of complications. The proportion of patients with chronic hepatitis B who meet this strategy has risen from 10.3% to 26.5%~33.9%, but it is still far from the World Health Organization's proposed treatment target of 80%. Therefore, in an attempt to achieve the goal of eliminating hepatitis B by 2030, a "treat all" strategy has been proposed, wherein all chronic hepatitis B patients who test positive for HBV DNA should be treated as early as possible.

Diagnosis and treatment of hepatitis B virus (HBV) infection in children is a hotspot of concern in the field of HBV infection. This article reviews the current status and progress of antiviral treatment for children with chronic hepatitis B (CHB) in recent years, focusing on clinical issues such as the choice of antiviral treatment regimen for children with HBeAg-positive CHB (immune-clearance phase), the necessity of antiviral treatment for children with HBeAg-positive HBV infection (immune-tolerance phase), and the timing of antiviral treatment for infants with HBV infection, to explore the relevant factors that may affect the clinical cure of children with CHB. At the same time, based on the expert consensus on the prevention and treatment of children with CHB just published by Chinese experts, relevant diagnosis and treatment plans are proposed, with a view to providing reference and basis for clinical decision-making in children with CHB.

The Chinese Society of Hepatology of the Chinese Medical Association invited relevant experts to revise and update the Guideline of Prevention and Treatment of Nonalcoholic Fatty Liver Disease (2018Version) and renamed it as (Version 2024) Guideline for the Prevention and Treatment of Metabolic Dysfunction-associated (non-alcoholic) Fatty Liver Disease. Herein, the guiding recommendations on clinical issues such as screening and monitoring, diagnosis and evaluation, treatment and follow-up of metabolic dysfunction-associated fatty liver disease are put forward.

Clinical cure (herein referred to as functional cure) is currently recognized as the ideal therapeutic goal by the guidelines for the prevention and treatment of chronic hepatitis B (CHB) at home and abroad. China has achieved significant results in research and exploration based on pegylated interferon alpha therapeutic strategies to promote the effectiveness of CHB clinical cure rates in clinical practice. The summary and optimization of clinical cure strategies in different clinical type classifications, as well as the exploration of clinical cure continuity and long-term outcomes, are of great significance for solving the current bottleneck problem and our future efforts in the developmental directions of clinical cure in CHB populations.

Liver fibrosis is a key step in the developmental process of various chronic liver diseases, including cirrhosis. Therefore, the focus and difficulty of liver disease research have always been on how to reverse liver fibrosis. However, due to complex mechanisms, difficulties in endpoint evaluation, a lack of non-invasive diagnostic methods, and other factors, the research and development of new drugs are hindered and lengthy. Currently, some new drugs are being researched and developed, which signifies the prospect is optimistic.
