Non-invasive vagus nerve stimulation (nVNS), including transcutaneous cervical (tcVNS) and auricular (taVNS) modalities, has garnered increasing attention as a neuromodulatory therapy for various neurological and psychiatric disorders. This narrative review synthesizes findings from over 80 studies, including randomized controlled trials, meta-analyses, and observational research published up to March 2024, evaluating nVNS in epilepsy, depression, stroke rehabilitation, headache, Parkinson’s disease, and Alzheimer’s disease. Evidence suggests that taVNS can reduce seizure frequency and improve quality of life in epilepsy. In major depressive disorder, nVNS demonstrates antidepressant effects comparable to pharmacotherapy, though the optimal stimulation parameters remain unclear. For post-stroke motor rehabilitation, both tcVNS and closed-loop stimulation systems enhance neuroplasticity and motor recovery. In Parkinson’s and Alzheimer’s diseases, preliminary findings indicate possible modulation of neuroinflammatory pathways and cognitive-motor functions, although recent meta-analyses report mixed efficacy. Challenges include methodological heterogeneity, protocol variability, and difficulties in designing effective sham controls, all of which limit the generalizability of current findings. Mechanistic differences between tcVNS and taVNS remain inadequately characterized. Overall, nVNS appears to be a safe and accessible therapeutic approach with broad clinical potential, particularly for treatment-resistant or underserved populations. However, future research must prioritize standardized protocols, robust clinical endpoints, and adequately powered trials to define efficacy and optimize treatment strategies. A greater focus on long-term outcomes, biomarker-guided personalization, and clinical significance over statistical findings will be critical in translating nVNS into routine practice.

Hepatic encephalopathy (HE) is a brain disorder secondary to cirrhosis, characterized by cognitive deficits, psychiatric manifestations, and motor impairments. It is associated with frequent hospitalizations, high mortality rates, and poor quality of life in cirrhotic patients. Additionally, ammonia and inflammation are key contributors to the onset of HE. Rifaximin is minimally absorbed in the intestine and is considered a locally acting, semi-synthetic antibiotic with broad-spectrum antibacterial activity. The pharmacological effects of rifaximin include reducing plasma ammonia levels, decreasing proinflammatory cytokine levels, and modulating gut microbiota and their functions. Currently, both Chinese and EASL clinical practice guidelines recommend rifaximin (800–1,200 mg/d) as a first-line treatment for HE for up to six months. However, the efficacy and safety of long-term (≥six months) use of rifaximin for HE remain debated. This review aimed to analyze the long-term (≥six months) use and dose-effect relationships of rifaximin treatment for HE. Long-term, low-dose use of rifaximin (600–800 mg/d) may offer potential benefits in terms of efficacy, safety, and cost-effectiveness.

Globally, the integration of traditional medicine and modern medicine has been recognized as a global health priority aimed at improving healthcare accessibility, cultural relevance, and therapeutic effectiveness. This review systematically examines the global landscape of traditional medicine-modern medicine integration by analyzing policy developments, regulatory frameworks, and clinical implementation models across various regions, including Asia, Africa, Europe, and the USA. The scope of the review encompasses five key domains: (1) global policy initiatives, (2) regulatory and institutional frameworks, (3) clinical integration models, (4) impacts and outcomes of integrative practices, and (5) challenges and barriers to implementation. Based on peer-reviewed literature and official health policy documents published between 2000 and 2025, the present review investigates how countries have operationalized clinical integration models combining traditional and complementary medicine. Although interest in traditional and complementary medicine has grown worldwide, persistent challenges, such as limited scientific validation, lack of standardization, and professional resistance, continue to hinder progress. This review concludes that successful and sustainable integration requires evidence-based clinical approaches, inclusive regulatory reforms, and coordinated policy strategies. Countries such as China, India, and Brazil have made significant advances, offering valuable models for future implementation worldwide.

Inflammatory bowel disease (IBD) is an idiopathic intestinal inflammatory condition affecting the ileum, colon, and rectum, including ulcerative colitis and Crohn’s disease. Clinical symptoms include abdominal pain, diarrhea, and even bloody stools. The intestinal barrier is the first line of defense between the intestinal tract and the external environment, and maintaining its stability is essential for intestinal health. On one hand, it enables the digestion and absorption of water and nutrients; on the other, it plays a crucial role in reducing the absorption of toxins and the invasion of pathogens. Damage to the intestinal barrier has become one of the most important factors in the onset and progression of IBD. However, there is currently no literature that systematically reviews the mechanisms of the intestinal barrier in the pathogenesis of IBD and the factors influencing it. In this paper, we aimed to systematically elaborate on the role of the intestinal barrier in IBD through the perspectives of oxidative stress, intestinal flora, and cellular autophagy. Our goal was to explore the mechanisms of the intestinal barrier in IBD more deeply and to provide new insights for the diagnosis and treatment of IBD. This article will summarize the composition of the intestinal barrier, the factors affecting it, and strategies to protect it.

Imbalanced autonomic function has been reported in gastrointestinal (GI) disorders. The vagus nerve is a major component in the regulation of upper GI motility. Vagal nerve stimulation (VNS) has been shown to improve symptoms of various GI disorders by enhancing parasympathetic activity. This review aims to summarize the clinical efficacy of transcutaneous VNS for GI disorders, focusing on abdominal pain, other GI symptoms, and GI motility, and to discuss the mechanisms of action of transcutaneous VNS. Randomized clinical trials investigating transcutaneous VNS in several major GI disorders, including functional dyspepsia, gastroparesis, constipation, irritable bowel syndrome, and inflammatory bowel disease, were reviewed and discussed. The forms of transcutaneous VNS covered in this review include transcutaneous auricular VNS, transcutaneous cervical VNS, and percutaneous electrical nerve field stimulation. Transcutaneous VNS has been shown to relieve abdominal pain, improve GI symptoms, and accelerate GI motility by enhancing vagal activity in patients with various GI disorders. Transcutaneous VNS is an innovative, effective, and safe therapy for patients with GI disorders; however, large-scale clinical trials are necessary to establish optimal treatment modalities and efficacy.

China has made remarkable progress in controlling chronic hepatitis B virus (HBV) infection over the past three decades. The prevalence of hepatitis B surface antigen has declined from 9.72% in 1992 to 5.86% in 2020, with a striking reduction from 9.67% to 0.30% among children under five. Universal hepatitis B vaccination has been pivotal, preventing more than 40 million infections and seven million HBV-related deaths since 1992. Nevertheless, an estimated 75 million individuals are currently living with chronic HBV infection in China. Among them, only 59.78% are aware of their infection status, and about 30 million remain undiagnosed. Of those diagnosed, 38.25% (approximately 17 million) meet the criteria for antiviral treatment, yet only 17.33% (about three million) are receiving treatment. To accelerate progress toward the World Health Organization’s elimination targets, China has updated its clinical guidelines to expand treatment eligibility and improve diagnosis and treatment coverage. Moreover, Chinese pharmaceutical companies and academic institutions are actively engaged in developing novel therapies with promising efficacy, aiming to achieve a functional cure. China’s holistic approach, combining evidence-based public health interventions with active clinical management and innovative pharmaceutical development, provides valuable experience for global HBV elimination initiatives. This review aimed to summarize China's progress in HBV control, identify remaining gaps in diagnosis and treatment, and highlight strategic approaches, including public health interventions, clinical policy updates, and pharmaceutical innovation, toward achieving HBV elimination.

Pancreatic cancer encompasses a heterogeneous group of malignancies, primarily divided into endocrine and exocrine types, with pancreatic ductal adenocarcinoma representing approximately 90% of cases. While the incidence of pancreatic cancer is relatively low, accounting for about 3% of all cancers in the United States, it has a disproportionately high mortality rate, responsible for around 7% of cancer-related deaths. In 2024, it is estimated that there will be 66,440 new diagnoses and 51,750 fatalities associated with this disease. The overall five-year survival rate remains alarmingly low at just 13%, primarily due to late-stage diagnosis; over 80% of pancreatic ductal adenocarcinoma patients present with unresectable tumors and metastases at the time of diagnosis. This review aims to highlight recent advancements in imaging and laboratory tests that are paving the way for innovative screening and diagnostic approaches. Some of the modalities discussed in detail include endoscopic ultrasound (EUS) and its modifications, such as EUS elastography, EUS contrast-enhanced, and EUS Fine Needle Aspiration, as well as multi-detector computed tomography scans, magnetic resonance imaging, and positron emission tomography scans. Furthermore, laboratory tests, such as multi-marker analysis and circulating tumor DNA, alongside traditional markers like carcinoembryonic antigen, carbohydrate antigen 19-9, and carbohydrate antigen 125, are explored. The role of radiomics and proteomics in the early detection of pancreatic cancer is also discussed. These developments hold the promise of improving early detection, which is crucial for enhancing patient outcomes in pancreatic cancer. On the treatment front, conventional therapies, including platinum-based therapies and monoclonal antibodies, are reviewed, alongside innovative therapies such as immunotherapies, chimeric antigen receptor T-cell therapy, and cancer vaccines. It has been increasingly recognized that the intricate patho-mechanisms underlying tumorigenesis in pancreatic cancers necessitate a deeper understanding to facilitate targeted therapeutic strategies. We also explore various newer therapies currently in clinical trials, assessing their practicality and effectiveness in real-world settings.

Liver fibrosis is a pathological process resulting from various chronic liver injuries that lead to the formation of liver fibrous scars. It can further progress to cirrhosis and even liver cancer. Currently, there are no effective drugs specifically approved for the treatment of liver fibrosis; etiological therapy remains the main treatment strategy. Therefore, it is necessary to develop anti-fibrotic drugs targeting different pathways involved in liver fibrosis. Transforming growth factor-beta (TGF-β) is a key driver of fibrosis, and targeting TGF-β can effectively reduce liver fibrosis. In this review, we discussed the anti-liver fibrosis effects of TGF-β inhibitors through different signaling pathways, including the application of certain active ingredients from Traditional Chinese Medicine.

High-grade endometrial carcinoma (HGEC) is an aggressive tumor with increasing incidence and mortality. Traditional classifications, such as Bokhman’s dualistic model and the World Health Organization histopathological system, have limitations due to tumor heterogeneity and interobserver variability. This review examines how integrating histopathological and molecular data, particularly The Cancer Genome Atlas (TCGA) classification, advances risk stratification and personalized treatment in HGEC. It highlights current challenges and identifies future directions to improve diagnostic accuracy and patient outcomes through precision medicine.

A literature review was conducted focusing on the epidemiology, histopathology, and molecular profiling of HGEC, with an emphasis on TCGA classification and next-generation sequencing studies.

TCGA molecular classification stratifies HGEC into four subgroups with distinct prognoses which includes POLE-ultramutated (POLE), microsatellite instability hypermutated, copy number high and copy number low. The next-generation sequencing enhances diagnostic precision and guides personalized treatment. However, diagnostic challenges persist in clinical practice.

Integrating histopathology with TCGA-based molecular profiling refines HGEC classification, enabling improved risk stratification and targeted therapies. Continued efforts to improve diagnostic accuracy are essential to advance patient care.

Amyotrophic lateral sclerosis (ALS) and other motor neuron diseases (MNDs) are major global causes of death. However, their global incidence, mortality, and disability-adjusted life years remain largely unknown, despite their importance for disease prevention and resource allocation. We therefore examined the global epidemiology of ALS/MNDs.

This study analyzed data from the Global Burden of Disease 2021 database for 204 regions (1990–2021), focusing on ALS/MNDs. Data from the world, China, and the G8 countries were analyzed separately. Age-standardized incidence rates were reported for the 1990s, 2000s, 2010s, and 2020s.

A rising global burden of ALS/MNDs, with significant variations across regions and levels of the social development index, was observed in the Global Burden of Disease database. A significant overlap of etiology between neurological diseases and ALS was also identified. Among the G8 countries and China, China and the USA exhibited the highest prevalence rates in the 1990s, 2000s, 2010s, and 2020s, with China showing 3.3 per 10,000 and the USA 4.0 per 10,000 in the 2020s.

Understanding the common etiologies of ALS/MNDs is key to their effective control. Recommended strategies include pollution control, chemical and radiation safety management, disease monitoring, public health education, multi-departmental collaboration, and scientific research.
