Summary: This study identified 372 differentially expressed circRNAs in peripheral blood mononuclear cells (PBMCs) of children with asthma. Among them, a circRNA called circS100A11 was highly expressed in monocytes and significantly upregulated in children with asthma. Further experiments demonstrated that circS100A11 promoted M2a macrophage activation by enhancing translation of its host gene, S100A11, and exacerbated lung inflammation in a mouse model of asthma. The study also found that circS100A11 competitively bound to CAPRIN1 to promote S100A11 translation, thereby enhancing M2a macrophage activation.

Summary: This paper focuses on the Largos of the Macau Peninsula and categorizes their main functions as serving the community, facilitating traffic, and promoting religious culture through historical combing and field research. A spatial syntactic theory is applied to establish a model, using three syntactic parameters - synergy, integration, and choice - to interpret the analysis results. Based on the syntactic parameters, the results are divided into four categories, and improvement strategies are proposed for the selected spaces that require enhancements. Taking Macau's Largos as an example, this paper aims to provide a reference for the effective renewal of urban micro-spaces and small public spaces by applying space syntax analysis.
