Background: Club cell secretory protein 16 (CC16) has protective roles in airway diseases, including anti-inflammatory, immunomodulatory, and antioxidant functions. This study investigates CC16's potential to repair lung injury from particulate matter 2.5 (PM) exposure in asthmatic mice.
View Article and Find Full Text PDFBackground: Exposure to PM2.5 represents a significant public health challenge, closely associated with the worsening of asthma, a condition that still lacks effective preventive measures. Club Cell 16 kDa protein (CC16), recognized for its anti-inflammatory and antioxidant properties, may serve a protective function in asthma exacerbated by PM2.
View Article and Find Full Text PDFBackground: Severe asthma (SA) is a chronic lung disease, resistant to current treatments, symbolized by repeated symptoms of reversible airflow obstruction, airway hyper-responsiveness, and inflammation. The aim of this study was to identify genes exhibiting differential expression in individuals without asthma and SA patients. We aimed to pinpoint hub differentially expressed genes (DEGs) by utilizing a mouse model of asthma sensitized to ovalbumin (OVA).

Methods: There were 211 ICU patients enrolled in this retrospective, nested case-control study. Participants were divided into an ARDS (n = 79) and non-ARDS (n = 132) groups, according to the Berlin criteria.
Background: Tracheal fistulas (TF) can be dangerous and even fatal in patients. The current treatment is really challenging. Previous studies reported that mesenchymal stem cells (MSCs) could be used to treat respiratory tract fistulas.

Out-of-hospital cardiac arrest (OHCA) with high mortality and disable rate is a public health problem of common concern all over the world. In order to improve the survival rate of OHCA, developed countries such as Europe and the United States have established regional and even national OHCA registration database for continuous monitoring and quality improvement of OHCA, identifying the weaknesses in each link of the survival chain, and evaluating effective measures to enhance the survival rate. At present, China still lacks of registration database that can comprehensively collect the information of OHCA and effectively reflect the treatment status and research direction of OHCA.

Objective: To share the implementation experience of hierarchical first aid training scheme for elementary and middle school students in Baoan District of Shenzhen City and evaluate its effect of training.
Methods: During August 2018 and August 2019, elementary and middle schools students who participated in the first aid training held by emergency rescue training center of Baoan District were enrolled. Baseline information including the number of students, the number of attending tutors, the number of cardiopulmonary resuscitation (CPR) training models, automated external defibrillator (AED) models were recorded.
Background: Contradictory results regarding changes in serum club cell protein 16 (CC16) levels in patients with acute respiratory distress syndrome (ARDS) have been reported, challenging the value of CC16 as a diagnostic and prognostic marker for ARDS. We have also observed increased serum CC16 levels in patients with renal dysfunction (RD). Therefore, the present study aimed to determine whether RD affects the diagnostic performance of CC16 for ARDS in intensive care unit (ICU) patients.
View Article and Find Full Text PDFObjective: Our previous clinical study showed that low lung levels of CC16 strongly influence the occurrence and development of ARDS. The aim of the present study was to evaluate the therapeutic effect of rCC16 on LPS-induced inflammation in A549 cells and to determine its mechanism.
Methods: Cell apoptosis and inflammation was induced by LPS stimulation.

Acute kidney injury (AKI) is a common complication in patients with sepsis, with poor prognosis and high mortality. The pathogenesis of sepsis-induced acute kidney injury (SAKI) is closely related to renal hemodynamic abnormalities, inflammatory injury and adaptive mechanism. It is insufficient for previous criteria based on urine output and creatinine to the early diagnosis of SAKI.

In this study, we aimed to study the effects of ROCK inhibition by fasudil on lung injury induced by asphyxial CA and CPR in rats. A total of 130 rats were randomized into three groups: Sham, Control, and Fasudil intervention group.

And it can be divided into two phases in pathophysiology: an acute exudative phase combining diffuse alveolar damage and lung edema followed by a later fibro proliferative phase. The early prediction and risk assessment of patients with ARDS is still very poor in the clinical.
View Article and Find Full Text PDFBackground: Acute respiratory distress syndrome (ARDS) is a critical condition characterized by bilateral pulmonary infiltrates and severe hypoxemia. This study aimed to evaluate the diagnostic and prognostic values of Club cell protein 16 (CC16) in critical care patients with ARDS.
Methods: In this retrospective observational study, 83 patients with ARDS and 129 non-ARDS patients on ICU admission were enrolled.
Lipopolysaccharide (LPS), a Gram-negative bacterial outer membrane component, is one of the major causes of septic shock. Herein we investigate LPS-induced apoptosis of rat alveolar epithelial type II cells (AEC II) and the effects of LPS on surfactant protein-C (SP-C) expression in AEC II, along with the possible molecular mechanisms. LPS exposure impaired cell viability and increased apoptosis of AEC II significantly in concentration-dependent manner embodied in increased caspase-3 expression and the activity of caspase-3.
