Non-alcoholic fatty liver disease (NAFLD) is a common concomitant disease in adults with type 2 diabetes mellitus (T2DM) and prediabetes. Therefore, T2DM/NAFLD patient populations are at high risk for cardiovascular disease. The occurrence and progression of non-alcoholic fatty liver disease-related liver fibrosis and cardiovascular disease have a severe impact on the patient's prognosis and mortality rate. The American Diabetes Association's 2024 "Guidelines for the Standardized Management of Diabetes" put forward recommendations relevant to the screening, evaluation, treatment, and management of NAFLD in T2DM and prediabetic populations, as well as liver fibrosis. The important measures for decelerating liver inflammation and fibrosis progression and the risk of cardiovascular disease are based on improvements in lifestyle methods, weight loss, and blood sugar control.

Chronic hepatitis B virus (HBV) infection is one of the major public health issues of ongoing global concern. Due to inadequate understanding of the HBV life cycle, there is a lack of effective drugs to cure chronic hepatitis B. During HBV replication, covalently closed circular DNA (cccDNA) serves as the template for viral replication and can be transcribed to produce five viral RNAs of 3.5, 2.4, 2.1 kb and 0.7 kb in length, which are translated to produce HBeAg, core protein, polymerase (P) protein, HBsAg and HBx proteins, respectively. Among them, the 3.5 kb pregenomic RNA (pgRNA) is also the template for viral reverse transcription. Polymerase protein recognizes and binds to the capsid assembly signal on the pgRNA to initiate capsid assembly and reverse transcription. Recent studies have revealed that the processes of splicing, nuclear export, stability, translation, and pgRNA encapsidation of HBV RNAs are regulated by a post-transcriptional regulatory network within the host cell and depend on unique post-transcriptional regulatory elements in the HBV RNA structure. The aim of this review is to overview the post-transcriptional regulatory mechanisms of HBV RNA and their applications in the study of HBV antiviral therapeutics, with the aim of providing new ideas for the development of new drugs targeting HBV RNA.

The World Health Organization (WHO) released the Global Health Sector Strategy 2016, which explicitly proposes a 90% reduction in the new hepatitis B virus (HBV) infection rate and a 65% reduction in HBV-related mortality by 2030. However, at present, there are still 296 million chronic hepatitis B virus-infected patients worldwide, and nearly 900,000 patients die every year from cirrhosis and liver cancer caused by HBV infection. Antiviral treatment for chronic hepatitis B virus infection can effectively inhibit HBV replication, reduce liver inflammation and necrosis, effectively block and reverse liver fibrosis, and even early cirrhosis, thereby lowering cirrhosis-related complications, liver cancer, and liver disease-related mortality. Although the domestic and foreign guidelines have gradually eased antiviral treatment indications for chronic hepatitis B, there are still a considerable number of chronic hepatitis B patients with nonconformity who cannot receive antiviral treatment because they do not meet the existing standards, resulting in the progression of more severe diseases. This study analyzed the prevalence of hepatitis B, the therapeutic effect of antiviral drugs, domestic and international guideline treatment standards, the assessment of key indicators changes in the guidelines, comprehensively considered the coverage rate and treatment standards for antiviral treatment, and explored the changes in disease burden and cost-effectiveness following increasing the coverage rate and reducing treatment thresholds in order to achieve the global strategic goal of eliminating hepatitis B as soon as possible as a public health threat.

Primary liver cancer is one of the most common malignant tumors. A liver tumor is defined as a large cancer when its diameter is ≥5 cm. Resection surgical therapy can be performed only on a small portion of large cancers because of its own features. As a result, non-resection surgical therapy has become a hot and difficult issue of widespread concern. In recent years, with the development of ablation technology, research on the use of ablation alone and ablation combined with other modalities for the treatment of large liver cancer has continued to deepen, and good clinical results have been achieved. Although there are many reports on ablation treatment for large liver cancer, there are currently no standardized treatment guidelines, and there are still controversies about treatment strategies. This article reviews the development of ablation therapy, the current status of single and combined ablation therapy, the prevention of related complications, and other aspects of large liver cancer.

The aim of this consensus is to standardize the prevention, diagnosis, and treatment of chronic hepatitis B in children and to achieve the goal of "eliminating viral hepatitis as a major public health threat by 2030" issued by the World Health Organization. Formulated by organized experts of the Chinese Society of Infectious Diseases and Chinese Society of Hepatology, Chinese Medical Association, Group of Infectious Diseases, Chinese Pediatric Society, Chinese Medical Association, and National Clinical Research Center for Infectious Diseases (Beijing), the consensus provides the latest evidence and recommendations for the prevention, diagnosis, and treatment of chronic hepatitis B in children.

Objective: To analyze and explore the clinical characteristics and risk factors related to nosocomial mortality in patients with liver cirrhosis combined with atrial arrhythmia. Methods: 252 hospitalized patients with liver cirrhosis combined with atrial arrhythmia from January 2014 to December 2021 were enrolled, and their clinical characteristics were analyzed. The above-mentioned patients were divided into groups according to their nosocomial mortality rate. Among them, 45 nosocomial mortality cases were classified as the mortality group, and 207 survival cases were classified as the survival group. The differences in clinical data and laboratory data between the two groups were compared. The risk factors for nosocomial mortality in patients with liver cirrhosis combined with atrial arrhythmia were analyzed. The t-test, or rank-sum test, was used to compare measurement data. The chi-square test, or Fisher's exact probability method, was used to compare enumeration data. Multivariate analysis was performed by the logistic regression method. Results: Among the 252 cases, the male-to-female ratio was the same (male/female ratio: 126/126). The age range was 26 to 89 (66.77±10.46) years. Han ethnicity accounted for 79.5%. The main type of atrial arrhythmia was atrial fibrillation (P < 0.001). The main cause of liver cirrhosis was post-hepatitis B cirrhosis (56.3%). There were 57/72/123 cases of CTP grade A/B/C. The CTP and Model for End-Stage Liver Disease (MELD) scores were 10.30±1.77 and 18.0(11.0, 29.0), respectively. The nosocomial mortality rate was 17.9% (45/252). The overall incidence rate of complications in all patients was 89.28%, with complications occurring in the following order: 71.4% ascites, 71.0% hypersplenism, 64.7% spontaneous peritonitis, 64.3% esophageal gastric varices, 32.5% hepatorenal syndrome, 32.1% hepatic encephalopathy, and 26.2% esophageal gastric variceal bleeding. The incidence rate of new-onset atrial fibrillation in the nosocomial mortality group was 73.3%, which was much higher than the 44.0% rate in the survival group (P < 0.05). Multivariate logistic regression analysis showed that new-onset atrial fibrillation (OR=2.707, 95%CI 1.119 ~ 6.549), esophageal-gastric varices (OR=3.287, 95%CI 1.189 ~ 9.085), serum potassium (OR=3.820, 95%CI 1.532 ~ 9.526), and MELD score (OR=1.108, 95%CI 1.061~1.157) were independent risk factors for nosocomial mortality in patients with liver cirrhosis combined with atrial arrhythmia. Conclusion: Patients with cirrhosis combined with atrial arrhythmias have more severe liver function damage and are more likely to develop complications such as ascites, hypersplenism, and hepatorenal syndrome. New-onset atrial fibrillation, esophageal-gastric varices, hyperkalemia, and a high MELD score are risk factors for nosocomial mortality in patients with liver cirrhosis combined with atrial ar

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.
