Airway epithelial cells constitute the first line of defense against external noxious stimuli and play crucial roles in release inflammatory cytokines (IL33, IL25 TSLP), initiating airway allergic diseases such as asthma. IL33 plays critical physiological processes T2-endotype However, mechanisms by which allergen exposure triggers from remain unclear. Integrated bioinformatic analysis transcriptional bulk RNA-seq single cell (scRNA-seq) data were used to identify core genes determine...

Respiratory syncytial virus (RSV) is one of the most common causes lower respiratory tract infections (LRTI). However, only limited information available regarding its seasonality and relationship with birth month. A retrospective hospital-based study was carried out from June 2009 to May 2019 in Chongqing, southwest China. LRTI cases under 5 years were enrolled this PCR used detect 8 viruses. RSV determined using "average annual percentage" (AAP) "percent positivity" method. total 6991...

EV-D68 is associated with respiratory tract infections (RTIs). Since its first isolation, has been detected sporadically. However, the US and Canada have experienced outbreaks of between August December 2014. This study aimed to investigate molecular epidemiology clinical characteristics in Chongqing, Southwestern China. From January 2012 November 2014, 1876 nasopharyngeal aspirate specimens (NPAs) were collected from hospitalized children RTIs. Among NPAs, was 19 samples (1.0%, 19/1876). Of...

Streptococcus pneumoniae (pneumococcus) is the most common respiratory pathogen worldwide. Nasopharyngeal carriage with S. major source of lower tract infection and horizontal spread among children. Investigating nasopharyngeal crucial for clinicians to control pneumococcus disease. Here, we retrospectively analyzed clinical information 5,960 hospitalized children, focusing on pneumonia children less than five years positive pneumococcal cultures. aspirates (NPAs) were collected between June...

Staphylococcus aureus (S. aureus) is a common cause of bacteremia, which leads to significant morbidity and mortality. We investigated the relationship between time positivity (TTP) clinical outcomes in children with S.aureus bacteremia China. A retrospective study inpatient was performed Children's Hospital Chongqing Medical University China 29 January 2014 August 2017. TTP parameters were determined analyzed. The receiver operating characteristic (ROC) curves plotted for optimal cut-off...

Abstract Background For pediatric pneumonia, the meteorological and air pollution indicators have been frequently investigated for their association with viral circulation but not impact on disease severity. Methods We performed a 10-year prospective, observational study in 1 hospital Chongqing, China, to recruit children pneumonia. Eight commonly seen respiratory viruses were tested. Autoregressive distributed lag (ADL) random forest (RF) models used fit monthly detection rates of each...
