Gastric cancer, Extracellular vesicles
Brief summary
After obtaining informed consent from the patients, all the medical history and treatment records of the patients who underwent gastroscopy since the onset of the disease, as well as gastric fluid samples, including laboratory and imaging data, were collected and recorded. The medical history and treatment records and gastric fluid samples were analyzed.
Interventions
DIAGNOSTIC_TESTIn vitro surface plasmon resonance detection
Gastric juice from patients was removed for isolation of extracellular vesicles and surface plasmon resonance detection in vitro
