Purpose To study the status of EGFR mutations and the expression of excision repair cross-complementation group 1 ( ER-CC1) and Ki-67 protein in patients with non-small cell lung cancer (NSCLC) and to examine the relationship between their expression and clinicopathologic features. Methods EGFR mutations were analyzed with DNA sequencing, and the expression of ERCC1 and Ki-67 protein was examined by immunohistochemistry EnVision. The relationship of EGFR mutations with the expression of ERCC1and Ki-67 and the clinicopathological features were analyzed. Results EGFR mutations were detected in 143 (143/291, 49. 1%) of the 291 specimens. EGFR mutations were found more frequently in women, non-smokers and adenocarcinoma. The difference of EGFR muta-tion rate between the histological subtypes according to the IASLC/ATS/ERS classification of lung adenocarcinoma was significantly ( P=0. 008). The mean tumor diameter was smaller in patients with EGFR mutations than in those with wild-type EGFR (P=0. 020). EGFR mutations were not related to age, lymph node metastasis. However, EGFR mutations were not related to the expression of ER-CC1 and Ki-67 protein (P>0. 050). Conclusions EGFR mutation is closely linked to several clinicopathological factors, such as gender, differentiation, and histological subtype. There is heterogeneity of EGFR mutation in patients with NSCLC. EGFR mutations were not related to the expression of ERCC1 and Ki-67 protein.

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.
