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.

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.

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.

Gastrointestinal (GI) health is essential for maintaining systemic balance, influencing digestion, immunity, and neuroendocrine signaling. However, GI disorders such as irritable bowel syndrome, inflammatory bowel disease, gastroesophageal reflux disease, peptic ulcers, and constipation are increasingly prevalent, significantly affecting global health and healthcare economics. Although conventional pharmacological treatments offer symptomatic relief, their long-term use is often associated with adverse effects, resistance, and limited efficacy, prompting a shift toward alternative and complementary therapies. Traditional systems of medicine, such as Ayurveda, Traditional Chinese Medicine, Unani, and Siddha, emphasize holistic approaches, including herbal formulations that target underlying causes rather than just symptoms. This review provides a comprehensive analysis of the role of natural products and traditional herbals in GI health. It discusses key bioactive constituents, flavonoids, alkaloids, terpenoids, and polyphenols, known for their anti-inflammatory, antimicrobial, gastroprotective, and prebiotic properties. Widely used herbal remedies such as Triphala, licorice root, peppermint oil, turmeric, and psyllium are highlighted for their proven therapeutic actions. Additionally, the review documents more than 300 medicinal plants traditionally used in diverse cultures worldwide for managing GI conditions, based on ethnopharmacological evidence. While the therapeutic promise is substantial, challenges such as formulation standardization, herb-drug interactions, and limited clinical data remain. The review underscores the need for integrating traditional wisdom with modern scientific validation, offering a path forward for safe, effective, and personalized GI healthcare.

Achalasia is a motility disorder of the esophagus, characterized by failure of relaxation of the lower esophageal sphincter and disordered peristalsis. Although it is a rare condition, its incidence is rising, likely due to advances in diagnostic techniques and the adoption of standardized definitions. Achalasia is associated with significant morbidity, and currently, there is no cure. Pharmacologic, endoscopic, and surgical interventions are aimed at symptom control. Laparoscopic Heller myotomy (LHM) has been the standard of care for achalasia since the 1990s. Over the past two decades, per-oral endoscopic myotomy (POEM) has emerged as a viable treatment option. Today, LHM and POEM represent the two most effective treatment modalities available for achalasia. This review aims to compare outcomes following LHM and POEM for achalasia and to explore patient characteristics and technical factors that guide optimal treatment selection. We examine the evidence regarding dysphagia relief, reflux, complications, and reintervention rates for both procedures, taking into account factors such as prior surgical history, achalasia subtype, and patient comorbidities.
