Brain and Nervous System

This is an open label, non-randomized, single site Phase I study to test the manufacturing feasibility and safety of locoregional (LR) administration of B7-H3CART into the central nervous system of adult subjects with recurrent IDH wild-type GBM using a standard 3+3 dose escalation design.

Functional dyspepsia (FD) is a chronic disorder of gut-brain interaction characterized by bothersome upper abdominal symptoms arising from the gastroduodenal region. Diagnosis is made after clinical evaluation has excluded structural disease that could explain symptoms (e.g., upper gastrointestinal endoscopy). According to Rome IV criteria, FD is categorized into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS), with symptom overlap commonly observed. FD is prevalent worldwide and is associated with substantial impairment in health-related quality of life and a significant socioeconomic burden. Sleep disturbance, anxiety, and depression are frequent in FD and are associated with symptom severity and recurrence. Current management-such as prokinetic agents, acid-suppressive therapy, and psychotropic medications when indicated-can be limited by variable efficacy, adverse effects, and concerns regarding long-term use. The pathophysiology of FD is multifactorial and incompletely understood; increasing evidence highlights dysregulation of the brain-gut axis and autonomic nervous system function (12,13). Auricular vagus nerve-related stimulation may influence brainstem neurotransmission, gastric tone/motility, and mood (14), suggesting a potentially safe, non-pharmacological approach for FD with comorbid sleep problems. However, the mechanistic links among autonomic regulation, gut microbiota/short-chain fatty acids, and FD remain uncertain. This study aims to evaluate the clinical efficacy and safety of auricular acupoint stimulation in FD patients with sleep disorders and to explore underlying mechanisms using brain-function assessments together with autonomic and gastrointestinal-related measures.
