Decision-making and Optimization of Ventilatory Support for AECOPD Patients

The goal of this retrospective observational study is to learn about how respiratory support is selected and adjusted in hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The main questions it aims to answer are: 1. How are different respiratory support modalities selected for patients with AECOPD in real-world practice? 2. What clinical patterns are associated with escalation, de-escalation, switching, or discontinuation of respiratory support during hospitalization? Researchers will review de-identified hospital records of patients admitted with AECOPD and analyze the dynamic use of respiratory support during hospitalization, including conventional oxygen therapy, high-flow nasal cannula oxygen therapy, non-invasive ventilation, and invasive mechanical ventilation. Participants will not receive any study-assigned intervention. The study will use existing clinical data collected during routine inpatient care and will not change diagnosis, treatment, or follow-up.

Effectiveness of Xuanfei Jiangzhuo Decoction for Influenza-Induced AECOPD

The goal of this observational study is to learn if a traditional Chinese herbal medicine (Xuanfei Jiangzhuo Decoction) works to help older adults recover from a COPD flare-up caused by the flu (influenza virus). The main questions it aims to answer are: Does the herbal medicine help participants feel better and recover faster? Does it lower the chance of getting a second infection from bacteria? Is the herbal medicine safe to use? Researchers will compare participants who choose to take the herbal medicine along with their standard flu treatment (Oseltamivir or Baloxavir) to participants who only take the standard flu treatment (Oseltamivir or Baloxavir). Participants will: Take the herbal medicine (a liquid drink) twice a day for 5 days, or just take their standard flu medicine for 5 days. Visit the clinic 4 times over 28 days for checkups and tests. Provide blood and stool samples to help researchers understand how the medicine affects the body and gut health. Answer simple questions about their cough, breathing, and energy levels.

Nasal High Flow Versus Non-invasive Ventilation for Early Treatment of Acute Exacerbation of Chronic Obstructive Pulmonary Disease With Hypercapnic Acidosis

The purpose of this study is to determine whether nasal high flow is non inferior to non invasive ventilation (NIV) in the early treatment of patients with acute exacerbation of chronic obstructive pulmonary disease (AE-COPD) and hypercapnic acidosis in the emergency department (ED). After obtaining informed consent, participants will be randomly assigned to receive either nasal high flow or non invasive ventilation (NIV, reference treatment) as respiratory support. Researchers will compare both respiratory support groups to see if their blood gas analysis and respiration return to normal ranges.

Safety, PK and PD Relationships of RLS-0071 in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease

AECOPD is a major cause of hospital admission and mortality. They contribute to long-term decline in lung function, physical capacity, and quality of life (QoL). RLS-0071 is a novel peptide being developed for the treatment of AECOPD. This study is designed to evaluate the safety and tolerability of RLS-0071 in the treatment of adults with moderate exacerbations of COPD.

The Severity Assessment Model for AECOPD With Combination of Disease and Syndrome

The establishment of the AECOPD severity assessment model can quickly and accurately evaluate the condition, which is of great significance for standardizing diagnosis and treatment, improving efficacy, and improving prognosis. At the same time, it can provide ideas and methods for the research of disease assessment models in related fields.

Study to Evaluate the Clinical Value and Safety of Xiyanping Injection in the Treatment of Acute Exacerbation of Chronic Obstructive Pulmonary Disease(COPD) Based on Real-world Clinical Data

The primary objective is to evaluate the effect of Xiyanping injection on the treatment course of intravenous antibiotics for acute exacerbation of chronic obstructive pulmonary disease based on real-world clinical data, and to provide guidance and basis for the clinical application of Xiyanping injection combined with antibiotics in the treatment of acute exacerbation of chronic obstructive pulmonary disease.The secondary objectives is to evaluate the effect of Xiyanping injection on the indicators of acute exacerbation of inflammation and symptom improvement of chronic obstructive pulmonary disease.

Impact of HI-NPPV Vs LI-NPPV on Tolerance Among AECOPD Patients

To determine whether high-intensity NPPV, compared with low-intensity NPPV, could have an effect on the subjective tolerance in patients with an AECOPD and hypercapnia.
