Etiological Characteristics and Risk Factors of Chronic Obstructive Pulmonary Disease Combined with Infection.
The distribution characteristics of pathogenic bacteria and the related health risk of pulmonary infection in patients with chronic obstructive pulmonary disease (COPD) were retrospectively analyzed to develop targeted measures to enhance patient prognosis. A retrospective analysis was conducted on the clinical data of 108 patients with COPD complicated with pulmonary infection and 108 patients without pulmonary infection. Analyze the distribution of pathogens in the lung infection group. ⋯ Forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) were significantly lower than in the group without pulmonary infection (P < 0.05). Multivariate Logistic regression analysis showed that unrelated health risks for pulmonary infection in COPD patients were age ≥ 60 years, length of hospitalization ≥ 15 days, combination of diabetes mellitus, and use of ≥ 2 types of antibacterial drugs. Age ≥ 60 years old, hospital stay ≥ 15 days, diabetes patients, and antibacterial drugs ≥ 2 are the risk factors of COPD patients with pulmonary infection.

Plasma MiR-21-5p and MiRNA-93-5p Levels as Early Assessment Tools for In-Stent Restenosis Following Endovascular Stenting Treatment in Patients with Lower Extremity Atherosclerotic Disease.
In-stent restenosis (ISR) still remains a leading cause of failure of interventional therapy in patients with lower extremity atherosclerotic disease (LEAD). Sensitive and reliable biomarkers to predict ISR should be identified. This study aims to investigate predictive values of two microRNAs, miR-21-5p and miR-93-5p for ISR following endovascular stenting treatment. ⋯ The plasma levels of miR-21-5p and miR-93-5p at 14 days after surgery used alone or combination as a test to predict ISR occurrence 6 months after surgery produced an AUC of 0.845, 0.839, and 0.906, respectively. Multiple logistic regression analysis revealed the plasma levels of miR-21-5p and miR-93-5p at 14 days after surgery were risk factors for LEAD patients developing ISR at 6 months after surgery (P < 0.001). Our results suggest that plasma miR-21-5p and miR-93-5p levels at 14 days after surgery may serve as potential biomarkers for developing ISR following endovascular stenting treatment among LEAD patients.
