To evaluate the differential expression profiles of the lncRNAs, miRNAs, mRNAs and ceRNAs, and their implication in the prognosis in clear cell renal cell carcinoma (CCRCC), the large sample genomics analysis technologies were used in this study. The RNA and miRNA sequencing data of CCRCC were obtained from The Cancer Genome Atlas (TCGA) database, and R software was used for gene expression analysis and survival analysis. Cytoscape software was used to construct the ceRNA network. The results showed that a total of 1 570 lncRNAs, 54 miRNAs, and 17 mRNAs were differentially expressed in CCRCC, and most of their expression levels were up-regulated (false discovery rate < 0.01 and absolute log fold change > 2). The ceRNA regulatory network showed the interaction between 89 differentially expressed lncRNAs and 9 differentially expressed miRNAs. Further survival analysis revealed that 38 lncRNAs (including COL18A1-AS1, TCL6, LINC00475, UCA1, WT1-AS, HOTTIP, PVT1, etc.) and 2 miRNAs (including miR-21 and miR-155) were correlated with the overall survival time of CCRCC ( < 0.05). Together, this study provided us several new evidences for the targeted therapy and prognosis assessment of CCRCC.

ObjectiveTo explore the research hotspots and development trends in the field of autism spectrum disorder (ASD) in the past ten years, the literatures of microglia-related neuroinflammation of ASD and the immune regulation and possible pathways of exercise ameliorating ASD symptoms were reviewed. MethodsArticles about microglia-related research in ASD during January, 2012 to December, 2021 were searched in the core collection database of Web of Science. The CiteSpace 5.8.R3 software was used to summarize the main findings, visualize and analyze the annual publication volume, high-frequency keywords and keyword clustering. Results and ConclusionA total of 783 papers were returned. The numbers of papers published increased with time. The neuroinflammation was a research hotspot in the pathogenesis of ASD, among which abnormal activation of microglia and the levels of inflammatory cytokines were important factors in the occurrence and development of ASD. Exercise was an important intervention to improve symptoms of ASD, which may associate with reducing neuroinflammation or regulating microglia-mediated inflammatory pathways.
