Mast cells play a central role in asthma. Moreover, serum miRNA-221-3p (miR-221) has been shown to be markedly increased in children with asthma. In the current study, we aimed to examine miR-221 expression in an asthma model and elucidate the mechanisms regulating interleukin (IL)-4 secretion in mast cells. Using polymerase chain reaction, we found that(More)
In this study, we aimed to assess the effects of microRNA-223 (miR-223) on interleukin-6 (IL-6) secretion in mast cells and determine the underlying molecular mechanisms. Mast cells (P815) were transfected with miR-223 lentiviral vector and miR-223 inhibitor. miR-223 expression was then evaluated using reverse transcription-quantitative PCR (RT-qPCR). IL-6(More)
The present study aimed to examine the functional role of miR-223 in the regulation of mast cell apoptosis. Overexpressed miR-223 in mast cells transfected by Lipofectamine 2000 was used as a model, and miR-223 was found to promote mast cell apoptosis. To investigate the underlying mechanisms involved, the potential and putative target molecules of miR-223(More)
OBJECTIVE To evaluate the value of clinical signs in the identification of Mycoplasma pneumonia in children's community acquired pneumonia. METHOD We searched the Cochrane library, PubMed, CNKI, Wan Fang and VIP databases. According to the inclusion and exclusion criterias, we selected and extracted the related information in the literature. According to(More)
