Silencing SMAD4 inhibits inflammation and ferroptosis in asthma by blocking the IL-17A signaling pathway.

Background: The TGF-β/SMAD signaling pathway is crucial in the pathogenesis of asthma. However, SMAD family member 4 (SMAD4), a key mediator of TGF-β, its roles and underlying mechanisms in asthma remain unclear.

Methods: The in vivo and in vitro roles of SMAD4 in asthma were investigated through an ovalbumin (OVA)-induced mouse model and an interleukin-13 (IL-13)-induced cell model.

Knockdown of KIF23 alleviates the progression of asthma by inhibiting pyroptosis.

Background: Asthma is a chronic disease affecting the lower respiratory tract, which can lead to death in severe cases. The cause of asthma is not fully known, so exploring its potential mechanism is necessary for the targeted therapy of asthma.

Method: Asthma mouse model was established with ovalbumin (OVA).

Construction and external validation of a nomogram model for predicting the risk of esophageal stricture after endoscopic submucosal dissection: a multicenter case-control study.

Esophageal stricture is a common complication after endoscopic submucosal dissection (ESD) for superficial esophageal cancer and precancerous lesions, we intend to investigate the independent risk factors of esophageal stricture after ESD by adding the data of included living habits, established a nomogram model to predict the risk of esophageal stricture, and verified it by external data. The clinical data and living habits of patients with early esophageal cancer and precancerous lesions who underwent ESD in the Affiliated Hospital of North Sichuan Medical College and Langzhong People's Hospital from March 2017 to August 2021 were retrospectively collected. The data collected from the two hospitals were used as the development group (n = 256) and the validation group (n = 105), respectively.

MiR-493-5p inhibits Th9 cell differentiation in allergic asthma by targeting FOXO1.

The role of micro RNAs (miRNAs) in asthma remains unclear. In this study, we examined the role of miRNA in targeting FOXO1 in asthma. Results showed that miR-493-5p was one of the differentially expressed miRNAs in the PBMCs of asthmatic children, and was also associated with Th cell differentiation.

Epidemiology of influenza in hospitalized children with respiratory tract infection in Suzhou area from 2016 to 2019.

Influenza is a contagious respiratory disease and risks public health in China, and it has caused wide public concern in recent years. Immunocompromised patients, such as children and elderly people, suffer more severe influenza complication and some extreme cases are even life threatening. To identify the influenza characteristics and its correlation with various climatic and environmental pollution factors, we collected the reported influenza epidemic of hospitalized children in Children's Hospital of Soochow University from 2016 to 2019.
