Lung cancer represents one of the most prevalent malignant tumors globally, and its treatment has entered the era of targeted therapy. The epidermal growth factor receptor (EGFR) mutation is a common type of genetic mutation in non-small cell lung cancer (NSCLC), while c-ros oncogene 1 receptor tyrosine kinase (ROS-1) fusion mutation is a rare mutation site. Currently, there are few case reports on the coexistence of EGFR and ROS-1 gene mutations. This study reports a case of NSCLC with coexisting EGFR and ROS-1 gene mutations, aiming to provide relevant treatment strategies for clinical practice.

Objective:To analyze the epidemiological features of respiratory syncytial virus (RSV) infection in Beijing, and monitor the sequence variations in RSV glycoprotein (G) gene and clinical features of infected children.Methods:Respiratory tract specimens were collected from children with acute respiratory infection in the Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 1, 2023 to December 31, 2023. RSV-positive specimens screened by multiple nucleic acid testing were subjected to PCR to amplify the full-length RSV G gene. A phylogenetic tree was constructed after gene sequencing to analyze RSV subtypes and trace G gene variants. Clinical data were retrieved from the medical record system to analyze the clinical features of children with RSV infection in Beijing.Results:A total of 5 489 respiratory specimens were collected from 3 046 male patients and 2 443 female patients. The average age of the patients was 4.36 years. A total of 589 RSV-positive specimens (10.7%, 589/5 489) were detected with 349 from male patients and 240 from female patients. The average age of children with RSV infection was (2.51±2.78) years and the median age was 0.48 years. RSV had been circulating among children in Beijing since March 2023 with two epidemic peaks in May (24.6%, 122/496) and December (18.2%, 126/693). The predominant subtype of RSV in the first half of 2023 was subtype A, but it was replaced by subtype B from November 2023. Phylogenetic analysis revealed a novel G gene of RSV subtype B (RSV-B-BA9-954bp) with a length of 954 bp, which belonged to a new cluster in the phylogenetic tree. The percentage of patients admitted to the Intensive Care Unit (ICU) was higher in children with new variant of RSV subtype B infection than in those with common RSV subtype B infection [44.1% (15/34) vs 25.2% (31/123), χ 2=4.600, P=0.032], while the counts of white blood cells and the levels of C-reactive protein were lower in the children with new variant infection ( P<0.05). Conclusions:RSV has been prevalent among children in Beijing since March 2023 with two epidemic peaks. The predominant A subtype is gradually replaced by to B subtype. A new variant of RSV B G gene (RSV-B-BA9-954bp) is detected among the children.

Objective:To analyze the differentially expressed genes of human respiratory syncytial virus (RSV) subtype A genotype ON1, a predominant genotype in Beijing, after infecting A549 cells using transcriptomic sequencing, and provide potential targets for RSV prevention and treatment.Methods:A local strain (61397-ON1) identified by whole-genome sequencing as ON1 genotype of RSV subtype A was selected to infect A549 cells. Total mRNA was extracted, and the differentially expressed genes in infected and uninfected A549 cells were screened by transcriptomic sequencing. GO analysis and KEGG pathway analysis were performed. Besides, six genes with differential expression ratio greater than two times were randomly selected for qRT-PCR verification.Results:There were 1 632 differentially expressed genes between infected and uninfected A549 cells, of which 807 genes were up-regulated and 825 genes were down-regulated. The differentially expressed genes were mainly involved in immune response-related biological processes such as cytokine response and positive regulation of MAPK cascades, and were enriched in MAPK signaling pathway, NOD-like receptor signaling pathway, p53 signaling pathway, TNF signaling pathway, IL-17 signaling pathway and NF-κB signaling pathway. The results of qRT-PCR for six differentially expressed genes were consistent with the trend of transcriptome data.Conclusions:The differentially expressed genes of RSV A subtype ON1 genotype after infecting A549 cells are mainly involved in cytokine response and immune-related signaling pathways. This study provides basic data for further study of the molecular mechanism of RSV infection and the development of prevention and treatment strategies.

AIM: Yi Qi Yang Yin Decoction (YQYY) has been used to treat patients with rheumatoid arthritis (RA) and achieved good results in clinical applications, but the mechanism still needs to be explored. The purpose was to investigate the mechanism of YQYY in rats with collagen-induced arthritis. METHODS: The possible treatment target and signaling pathway were predicted by bioinformatics and network pharmacology analysis. Elisa,quantitative real-time polymerase chain reaction, and Western Blot were used to verify the mechanism of YQYY in treating RA. RESULTS: FABP4, MMP9 and PTGS2 were the most common predicational therapeutic targets. The results of pathology and CT showed that YQYY could improve ankle swelling, synovitis and bone erosion in CIA rats. Compared with the model group, YQYY or YQYY+MTX can significantly reduce the secretion of CRP, TNF-α, IL-1β and FABP4 in serum of CIA rats (P<0.05 or P<0.01), meanwhile, reduce the mRNA of FABP4, IKKα and p65 in synovial tissue (P<0.01), PPARγ was increased (P<0.01). YQYY could significantly reduce the expression of FABP4, IKKα and pp65 proteins in synovium, and suppress the activate of NF - κB signaling pathway. CONCLUSION: FABP4, MMP9 and PTGS2 may be the targets of YQYY decoction for RA treatment. YQYY can relieve joint symptoms in CIA rats, and regulate inflammation by inhibiting FABP4 / PPARγ/NF - κB signaling pathway, playing a role in the treatment of RA. The effect of YQYY combined with MTX was more prominent. This provided experimental evidence for the efficacy of YQYY decoction in clinical practice.
