Application of narrow band imaging in the diagnosis of pharyngeal tumors.

Background: Narrow-band imaging (NBI) endoscopy is used in various tumor detection and is important in detecting early tumors.

Objective: To explore the application value of NBI endoscopy in diagnosing pharyngeal tumors.

Material And Methods: Ninety-one patients with pharyngeal masses who attended the Department of Otorhinolaryngology, Head and Neck Surgery in Gansu Provincial Hospital from January 2023 to February 2024 were selected, and NBI and white light (WL) endoscopy were applied to examine the pharynx and the relationship between the two was observed.

A case of deep neck abscess treated with a disposable VSD wound care device: Case report and review of literature.

Rationale: Vacuum sealing drainage is a novel technique for wound treatment that is characterized by adequate drainage and promotes wound healing. We report a case in which negative pressure sealing drainage was applied to treat a deep cervical abscess and achieved a good therapeutic effect.

Patient Concerns: The abscess in the neck will go down.

Application of B-Type Natriuretic Peptide in Neonatal Diseases.

Numerous congenital or secondary diseases, including, heart disease, respiratory disease, sepsis and many others, can lead to neonatal death. B-type natriuretic peptide (BNP) is a peptide hormone secreted by ventricular cells following an increase in ventricular wall tension. BNP functions to promote vasodilation, diuresis, and sodium release to regulate blood pressure.
