Chronic liver disease (CLD) is a major global health challenge, characterized by chronic inflammation that can progress to liver fibrosis, cirrhosis, and ultimately hepatocellular carcinoma. Early identification of biomarkers is crucial for effective intervention. Traditional Chinese medicine (TCM) has shown potential in improving CLD symptoms and protecting the liver, although its mechanisms remain unclear. Metabolomics, the comprehensive study of metabolites, offers a promising approach to understanding CLD pathogenesis and identifying biomarkers. Notably, metabolomics aligns with TCM’s holistic approach and may help reveal its therapeutic mechanisms. This review summarizes key metabolites associated with CLD diagnosis and progression and discusses how TCM may modulate metabolic pathways to alleviate CLD symptoms. These insights could lead to improved diagnostic and therapeutic strategies for CLD.

Lung metastasis is common in hepatocellular carcinoma (HCC) and is typically associated with a poor prognosis. In this report, we present a case of advanced HCC in a 46-year-old Chinese male with lung metastases. The patient received two cycles of sequential hepatic arterial infusion chemotherapy and transarterial embolization in combination with lenvatinib (a tyrosine kinase inhibitor) and tislelizumab (a programmed cell death protein 1 immune checkpoint inhibitor). After three months of treatment, the intrahepatic tumors showed a partial response, while the bilateral lung metastases exhibited a complete response. Concurrently, levels of alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II decreased to normal levels. Systemic treatment with lenvatinib and tislelizumab was continued for 10 months. This case underscores the potential of combination therapies for advanced HCC with lung metastases and provides a novel perspective on a therapeutic approach involving sequential hepatic arterial infusion chemotherapy and transarterial embolization with immune checkpoint and tyrosine kinase inhibitors.

Leishmaniasis is a systemic parasitic disease that can affect unusual sites such as the lungs.

We report a case of a 45-year-old male with human immunodeficiency virus infection who presented with abdominal pain and vomiting. Imaging studies revealed minimal bilateral ground-glass opacities in the lungs, hepatosplenomegaly, and diffuse lymphadenopathy. A bronchoscopy with bronchoalveolar lavage cytology evaluation showed abundant macrophages containing numerous intracellular organisms with characteristic dot-like kinetoplasts, confirming the diagnosis of Leishmaniasis. Special stains for other infections were negative.

This case highlights the value of bronchoalveolar lavage cytology in diagnosing non-neoplastic lung pathologies, including parasitic infections like Leishmaniasis, thereby enabling prompt and targeted treatment.

Coronary heart disease is an ischemic condition characterized by vascular stenosis or obstruction caused by coronary atherosclerosis, resulting in myocardial ischemia, hypoxia, or necrosis. It is one of the leading causes of death in both urban and rural populations in China. Safflower yellow pigments, the main active components of the traditional Chinese herbal medicine safflower, are primarily composed of quinochalcone compounds, including hydroxysafflor yellow A and anhydrosafflor yellow B—of which hydroxysafflor yellow A is the principal component. Studies have demonstrated that these pigments can improve myocardial ischemia, reduce ischemia-reperfusion injury, alleviate atherosclerotic damage, and address risk factors associated with coronary heart disease. This review aimed to systematically and comprehensively summarize the mechanisms of action of safflower yellow pigments and their active components in the context of coronary heart disease and its related risk factors.

Fat mass and obesity-associated protein (FTO) has been linked to various cancers, though its role in hepatocellular carcinoma (HCC) remains unclear. This study aimed to investigate FTO expression, its clinical relevance, functional role in HCC progression, and the underlying molecular mechanisms.

Quantitative reverse-transcription polymerase chain reaction and immunohistochemical analysis were used to assess FTO expression in HCC. Functional assays, including proliferation, invasion, and epithelial-mesenchymal transition studies, were conducted using HCC cell lines with FTO knockdown. N6-methyladenosine (m6A) RNA immunoprecipitation and RNA stability assays further elucidated the role of FTO in BUB1 mRNA methylation and stability. Co-immunoprecipitation studies were employed to confirm the interaction between BUB1 and TGF-βR1. In vivo studies in nude mice were conducted to evaluate tumor growth following FTO knockdown.

FTO was significantly upregulated in HCC tissues compared to normal liver tissues, with higher expression observed in advanced tumor-node-metastasis stages and metastatic HCC. Elevated FTO correlated with poor overall survival in patients. Silencing FTO decreased HCC cell proliferation, colony formation, invasion, epithelial-mesenchymal transition, and tumor growth in nude mice. Mechanistically, FTO downregulation led to increased m6A modification of BUB1 mRNA, thereby promoting its degradation via the YTH domain family 2-dependent pathway and reducing BUB1 protein levels. Additionally, BUB1 physically interacted with TGF-βR1, activating downstream TGF-β signaling.

FTO is overexpressed in HCC and is associated with poor clinical outcomes. Mechanistically, FTO promotes HCC progression by stabilizing BUB1 mRNA through an m6A-YTH domain family 2–dependent pathway, which activates TGF-β signaling. Targeting the FTO–BUB1–TGF-βR1 regulatory network may offer a promising therapeutic strategy for HCC.

Glioblastoma is the most common primary tumor of the central nervous system, characterized by an infiltrative growth pattern, which results in the most unfavorable prognosis. The average survival time of patients after diagnosis of this tumor is typically several months, with complete recovery from glioma being very rare. In recent years, significant involvement of exosomes in the development of cancer, including malignant brain tumors, has been discovered. Exosomes are extracellular vesicles that carry signaling molecules and participate in communication between cells. They influence cell survival, proliferation, migration, and increased neoangiogenesis, all of which significantly contribute to tumor recurrence. Molecules carried by exosomes are considered potential diagnostic markers, enabling early diagnosis of cancer and prompt implementation of appropriate treatment. Of particular diagnostic importance are microRNA molecules, which promote increased cell proliferation and inhibition of apoptosis. Equally important exosomal transmitters include proteins such as PSMD2 and EGFR, which enhance tumor invasiveness and resistance to chemotherapeutic agents. Recent studies suggest the possibility of using exosomes as carriers for new anticancer drugs, potentially improving the therapeutic treatment of cancers resistant to standard treatment methods. This review aimed to provide a comprehensive analysis of recent research on glioblastoma, the role of exosomes in its progression, the potential of exosomes as diagnostic biomarkers, and their use as therapeutic targets for patients who have not responded to conventional treatments.

This study investigates upper gastrointestinal tract (UGIT) involvement in patients with ulcerative colitis (UC), a condition traditionally considered limited to the colon. Although extra-colonic manifestations of UC are well recognized, UGIT issues have received less attention. This research aimed to document the clinical, endoscopic, and histopathological UGIT findings in adults with UC and assess their association with disease severity and extent.

This descriptive cross-sectional study was conducted at Ain Shams University over one year. A total of 78 UC patients underwent comprehensive clinical evaluations, including assessments of gastrointestinal complaints, medication history, disease progression, surgeries, and physical examinations. Endoscopic assessments of both the UGIT and colon were performed, accompanied by biopsies for histopathological analysis.

The study population had a mean age of 35.26 years, with a nearly equal gender distribution. Endoscopic findings revealed significant UGIT involvement: 64% of patients had esophagitis and/or gastroesophageal reflux disease, 93% had gastritis, and 80% had duodenitis. Histopathological findings showed notable inflammation, basal cell hyperplasia, and ulcerations in the esophagus, with 51.3% of patients exhibiting chronic gastritis and 38.5% testing positive for Helicobacter pylori infection. Statistical analysis demonstrated a strong association between colonic disease severity and UGIT endoscopic (p < 0.0001 and p < 0.001 in the esophagus and stomach, respectively) and histopathological (p < 0.004, p < 0.001, and p <0.005 in the esophagus, stomach, and duodenum, respectively) findings, particularly in patients with UGIT symptoms.

This study concludes that UGIT endoscopic and histopathological changes are prevalent among Egyptian UC patients, suggesting a significant link between UC and these UGIT findings.

Actively identifying the risk factors and predictive indicators associated with portal vein thrombosis (PVT) in liver cirrhosis (LC) can enable early diagnosis and treatment, which is of great significance for prolonging the survival of patients with LC. Hemodynamic disturbances, advanced LC, vascular endothelial injury, and mutations in thrombophilic genetic factors are established risk factors for PVT-LC. Venous dilatation and decreased blood flow velocity contribute to hemodynamic disturbances. The severity of LC can be assessed by the degree of portal hypertension, liver metabolic function biomarkers, and validated liver scoring systems. Iatrogenic interventions, endotoxemia, and metabolic syndrome may induce vascular endothelial injury and hypercoagulability, the latter of which can be quantified via coagulation-anticoagulation-fibrinolysis biomarkers. Mutations in thrombophilic genetic factors, such as Factor V Leiden, MTHFR C667T, and JAK2 V617F, disrupt coagulation-anticoagulation homeostasis and predispose patients to PVT-LC. This review specifically focuses on comprehensively delineating established risk factors and predictive indicators for PVT-LC, thereby providing a theoretical foundation for the construction of clinically applicable PVT predictive models to guide early interventions and improve the prognosis. Future research should further validate the associations between recently proposed risk factors and PVT-LC, while simultaneously establishing cutoff values for indicators with robust predictive value to construct a clinically applicable PVT prediction framework.

Hepatic biliary adenofibroma is an exceedingly rare biliary neoplasm that primarily affects adults. It typically presents as a solitary mass composed of low-grade microcystic and tubuloglandular bile duct structures, which are lined by low columnar to cuboidal non-mucin-producing biliary epithelium and supported by abundant fibrous stroma. Histologically, it resembles the Von Meyenburg complex but is much larger in size and often shows cytologic atypia. Although considered benign, emerging case studies and analyses suggest that biliary adenofibroma may serve as a precursor lesion to intrahepatic cholangiocarcinoma. However, its extreme rarity, coupled with an incompletely understood histogenesis, perpetuates diagnostic uncertainty and may lead to misclassification with other similar entities. This review consolidates the current understanding of the histopathological and molecular characteristics of biliary adenofibroma, highlights its differential diagnosis, explores its potential progression to cholangiocarcinoma, and discusses unresolved questions while proposing future research directions.
