Liver cancer is a digestive system malignancy that poses a significant public health challenge globally. This study aimed to analyze and compare the epidemiological trends of liver cancer attributed to hepatitis B (LCHB) and alcohol use (LCAL) over the past 32 years.

Data on mortality and disability-adjusted life years for LCHB and LCAL in China, globally, and across five sociodemographic index regions were obtained from the Global Burden of Disease 2021 database and comprehensively analyzed.

In 2021, the global and Chinese death counts and disability-adjusted life years attributed to LCHB and LCAL showed substantial increases compared to 1990. China had the highest number of deaths from LCHB and LCAL among 204 countries and regions. Gender and age disparities were notable, with males and those aged 40–75 years bearing a higher burden than females and other age groups. Global age-period-cohort analysis revealed an escalating risk of death from LCHB with age, alongside a lower risk in younger cohorts and more recent periods. The mortality risk for LCAL also increased with age but exhibited distinct cohort and period effects compared to LCHB. Decomposition analysis indicated that shifts in the global burden of LCHB and LCAL were influenced by population growth, with population aging playing a crucial role in China.

A significant burden of LCHB and LCAL persists, highlighting the need for tailored prevention, screening, and control strategies to mitigate their incidence, as well as the identification of advanced therapeutics to reduce mortality.

Necroptosis is critical for regulating intestinal epithelial cells (IECs). Butyric acid (BA), produced during intestinal microbial metabolism, protects the intestinal epithelial barrier. However, whether necroptosis occurs in IECs during liver cirrhosis and whether sodium butyrate (NaB) can regulate necroptosis have not yet been reported. In this study, we aimed to investigate whether IECs undergo necroptosis in cirrhosis and whether NaB can regulate necroptosis and the related regulatory mechanisms.

Serum levels of RIPK3, MLKL, and Zonulin, as well as fecal BA levels, were measured and correlated in 48 patients with liver cirrhosis and 20 healthy controls. A rat model of liver cirrhosis was established, and NaB was administered. The expressions of MLKL, p-MLKL, and tight junction proteins were measured. We conducted an in vitro investigation of the effect of NaB on necroptosis in the HT29 cell line.

Serum levels of RIPK3, MLKL, and Zonulin in the liver cirrhosis group were higher, while fecal BA levels were lower than those in the control group. Zonulin levels were positively correlated with RIPK3 and MLKL levels, while fecal BA levels were negatively correlated with serum MLKL levels, but not with RIPK3 levels. NaB reduced the mRNA and protein expression of MLKL but had no effect on RIPK1 and RIPK3 in vitro. Rescue experiments demonstrated that NaB inhibited necroptosis through E2F1-mediated regulation of MLKL.

NaB alleviates intestinal mucosal injury and reduces necroptosis in IECs in liver cirrhosis. It also inhibits the necroptosis of IECs and protects the intestinal barrier by reducing E2F1 expression and downregulating MLKL expression levels. These results can be employed to develop a novel strategy for treating complications arising from liver cirrhosis.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is currently a pressing public health issue associated with adverse outcomes such as cirrhosis, malignancy, transplantation, and mortality. Lifestyle modifications constitute the most effective and fundamental management approach, but they often pose challenges in sustaining long-term clinical benefits. Hence, there is a critical need to enhance our understanding through pharmacological management, which unfortunately remains limited. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have emerged as a leading treatment in the fields of diabetes and obesity, with recent preclinical and clinical studies indicating significant benefits in the management and treatment of MASLD. Our article begins by reviewing the beneficial therapeutic components of GLP-1RAs in MASLD. Subsequently, from a clinical research perspective, we concluded with the liver outcomes of current primary GLP-1RAs and co-agonists. Finally, we presented our insights on clinical concerns such as appropriate trial endpoints, management of comorbidities, and future developments. In conclusion, the benefits of GLP-1RAs in MASLD are promising, and background therapy involving metabolic modulation may represent one of the future therapeutic paradigms.

With the rising epidemic of obesity, metabolic syndrome, and type 2 diabetes mellitus in China, metabolic dysfunction-associated non-alcoholic fatty liver disease has become the most prevalent chronic liver disease. This condition frequently occurs in Chinese patients with alcoholic liver disease and chronic hepatitis B. To address the impending public health crisis of non-alcoholic fatty liver disease and its underlying metabolic issues, the Chinese Society of Hepatology and the Chinese Medical Association convened a panel of clinical experts to revise and update the “Guideline of prevention and treatment of non-alcoholic fatty liver disease (2018, China)”. The new edition, titled “Guideline for the prevention and treatment of metabolic dysfunction-associated fatty liver disease (Version 2024)”, offers comprehensive recommendations on key clinical issues, including screening and monitoring, diagnosis and evaluation, treatment, and follow-up for metabolic dysfunction-associated fatty liver disease and metabolic dysfunction-associated steatotic liver disease. Metabolic dysfunction-associated fatty liver disease is now the preferred English term and is used interchangeably with metabolic dysfunction-associated steatotic liver disease. Additionally, the guideline emphasizes the importance of multidisciplinary collaboration among hepatologists and other specialists to manage cardiometabolic disorders and liver disease effectively.

Portal vein thrombosis (PVT) is a challenging complication in liver cirrhosis, with no currently available sensitive diagnostic markers. This study aimed to investigate the potential of neutrophil extracellular traps (NETs) and Deoxyribonuclease (DNase) as diagnostic indicators for PVT in chronic hepatitis B (CHB)-related decompensated cirrhosis.

We analyzed 145 CHB-related decompensated cirrhosis patients from the Ditan study and 33 from the Changgung validation study, categorizing them based on PVT occurrence. Plasma samples were assessed for NET markers, including cell-free DNA (cfDNA) and histone-DNA complexes, along with DNase activity.

PVT patients exhibited elevated levels of cfDNA and histone-DNA complexes, and reduced DNase activity. This pattern persisted regardless of hepatocellular carcinoma (HCC) status. Histone-DNA levels, DNase activity, and hemoglobin were identified as independent risk factors for PVT. Receiver operating characteristic curve analysis revealed that high histone-DNA levels may serve as a potential diagnostic marker for PVT, with an area under the curve of 0.8628 in the Ditan study and 0.7521 in the Changgung study. When combined with cfDNA and DNase activity, the area under the curve improved to 0.8774 in the Ditan study and 0.7975 in the Changgung study.

Imbalances in NET homeostasis are associated with PVT in CHB-related decompensated cirrhosis, including cases involving HCC. Histone-DNA complexes, a significant risk factor for PVT, show potential as a diagnostic marker for PVT in decompensated cirrhosis, particularly in HBV-related HCC.

Paget’s disease of the esophagus is extremely rare, with few cases reported. In this report, we describe a case of recurrent esophageal Paget’s disease coexisting with small cell carcinoma. A 63-year-old man presented with the chief complaint of a rediscovered early esophageal cancer. Endoscopic examination revealed two separate superficial flat tumors in the upper and mid esophagus. Endoscopic submucosal dissection was performed, diagnosing diffuse Paget’s disease (5.5 × 3.5 cm) and a small focus on intramucosal squamous cell carcinoma, respectively. Paget’s cells were also found in the distal and right margins of the first specimen of endoscopic submucosal dissection. Immunohistochemical analysis showed that Paget’s disease diffusely expressed cytokeratin 7 (CK7), CK18, and mucin 6 (MUC6), and focally expressed CD56 and chromogranin A, but not CK5/6, p63, p40, MUC5AC, MUC2, or synaptophysin. A complete absence of p53 and Rb1 was observed in Paget’s disease. However, overexpression of p53 and retention of Rb1 were seen in squamous cell carcinoma. Approximately 27 months later, a prominent tumor was found at the same location as the previous Paget’s disease. Subsequently, radical surgery was performed, and the final pathological evaluation revealed esophageal small cell carcinoma coexisting with Paget’s disease. Moreover, both p53 and Rb1 were completely absent in both Paget’s disease and the small cell carcinoma. This suggests that esophageal Paget’s disease may dedifferentiate and develop into small cell carcinoma. In conclusion, esophageal Paget’s disease can co-occur with invasive carcinomas, including small cell carcinoma, and should be completely resected endoscopically, with close follow-up.
