The airway inflammation induced by nasal inoculation of PM2.5 and the treatment of bacterial lysates in rats.

Particulate matter (PM) is one of the most important environmental issues in China. This study aimed to explore the correlation between PM2.5 and airway inflammation in healthy rats.

Association between PTPN22/CTLA-4 Gene Polymorphism and Allergic Rhinitis with Asthma in Children.

Allergic rhinitis (AR) is an IgE-mediated upper airway disease, and its impact on asthma has been widely recognized. Protein tyrosine phosphatase non-receptor 22 (PTPN22) gene and the cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) gene polymorphisms have been reported to be associated with several immune-related diseases. Here we investigated the reffect of these two genes' polymorphisms on the risk of AR and asthma in Chinese Han children.
