Distribution and Drug Resistance of Common Pathogens Causing Lower Respiratory Tract Infection in Xinjiang Region.

Objective: This study aims to analyze the composition and distribution of pathogenic bacteria in lower respiratory tract infections (LRTI) and their antimicrobial resistance patterns in a hospital in Xinjiang, to guide more effective antibiotic selection and inform clinical management.

Methods: We retrospectively analyzed 545 strains isolated from various clinical specimens like sputum and blood, collected between June 2020 and June 2023, using the LIST system. The strains were subjected to drug resistance testing, and statistical analyses included t tests and Chi-square tests.

Use of aquaporins 1 and 5 levels as a diagnostic marker in mild-to-moderate adult-onset asthma.

Characteristic features of asthma include airway inflammation and hyperactivity, mucus hypersecretion, mucosal edema, and airway remodeling. These features could be due to pathological water transport across pulmonary epithelia and aquaporins (AQPs) have recently been isolated as key proteins in fluid transportation in the human respiratory tract. We aimed to evaluate the role of aquaporins in the pathogenesis of asthma and their possible use a diagnostic marker of the disease.
