Abstract
Pneumonia is a serious respiratory tract infection disease in children, which threatens to the health or life of children patients. Ginsenoside Rb1 (Rb1) is a principle active ingredient extracted from the root of Panax notoginseng (Burk.) F.H. Chen with anti-inflammatory effect. Our study aimed to determine the effects and molecular mechanisms of Rb1 on lipopolysaccharide (LPS)-induced inflammatory injury of lung fibroblasts WI-38 cells. Cell viability and apoptosis were evaluated by CCK-8 and flow cytometry, respectively. The production of inflammatory cytokines were measured by ELISA and RT-qPCR. miR-222 expression was examined by RT-qPCR. The expression levels of the nuclear factor-kappa B (NF-κB) p65 and phosphorylated p65 were detected by western blot. We found that LPS stimulation induced WI-38 cell inflammatory injury by inhibiting cell viability, and inducing apoptosis and inflammatory cytokine production, while treatment with Rb1 significantly attenuated LPS-induced inflammatory injury in WI-38 cells. Additionally, Rb1 decreased LPS-induced upregulation of miR-222 and activation of the NF-κB pathway in WI-38 cells. Overexpression of miR-222 abolished the inhibitory effects of Rb1 on LPS-induced viability reduction, apoptosis, inflammatory cytokine production and activation of the NF-κB pathway. In conclusion, Rb1 alleviated LPS-induced inflammatory injury in WI-38 cells via downregulating miR-222 and inactivation of the NF-kB pathway.

Abstract
Andrias davidianus is a large and economically important amphibian in China. Ranavirus infection causes serious losses in A. davidianus farming industry. MicroRNA mediated host-pathogen interactions are important in antiviral defense. In this study, five small-RNA libraries from ranavirus infected and non-infected A. davidianus spleens were sequenced using high throughput sequencing. The miRNA expression pattern, potential functions, and target genes were investigated. In total, 1356 known and 431 novel miRNAs were discovered. GO and KEGG analysis revealed that certain miRNA target genes are associated with apoptotic, signal pathway, and immune response categories. Analysis identified 82 downregulated and 9 upregulated differentially expressed miRNAs, whose putative target genes are involved in pattern-recognition receptor signaling pathways and immune response. These findings suggested miRNAs play key roles in A. davidianus's response to ranavirus and could provide a reference for further miRNA functional identification, leading to novel approaches to improve A. davidianus ranavirus resistance.

Abstract
Pneumonia is a common respiratory disease worldwide, which is preventable and treatable; however, it is recognized as a leading cause of mortality in children. The present study aimed to investigate the role and mechanism of microRNA (miR)‑20a in inflammation in pediatric pneumonia. Clinical serum samples were collected from children with pneumonia and healthy children. Initially, the serum expression levels of miR‑20a were detected by reverse transcription‑quantitative polymerase chain reaction. Subsequently, A549 cells were randomly divided into four groups: Control group; lipopolysaccharide (LPS; 1 µg/ml) group; LPS + miR‑20a group; and LPS + miR‑20a + pyrrolidine dithiocarbamate (PDTC; 100 mmol/l) group. The concentrations of interleukin‑6 (IL‑6), tumor necrosis factor (TNF)‑α and C‑reactive protein (CRP) in clinical serum samples and A549 cells were determined by ELISA. In addition, the protein expression levels of inhibitor of nuclear factor (NF)‑κB α (IκBα) and phosphorylated (p)‑NF‑κB were measured by western blotting. The results demonstrated that miR‑20a was upregulated in children with pneumonia and in lung cells with LPS‑induced inflammatory injury (P<0.01). In addition, compared with the LPS group, cells in the LPS + miR‑20a group exhibited increased expression levels of IL‑6, TNF‑α and CRP (P<0.05). Overexpression of miR‑20a also resulted in upregulation of the expression levels of IκBα and p‑NF‑κB compared with in the LPS group (P<0.05). Furthermore, treatment with the NF‑κB inhibitor PDTC inhibited the expression of inflammatory factors compared with in the LPS + miR‑20a group (P<0.05). In conclusion, the present study indicated that miR‑20a is upregulated in pediatric pneumonia, and overexpression of miR‑20a may promote inflammation through activation of the NF‑κB signaling pathway.

Abstract
MicroRNAs (miRNAs) are a class of noncoding RNA molecules and play important roles in a wide spectrum of biological processes, including in immune response. Recent years have witnessed considerable amount of research interest in studies on miRNA-mediated modulation gene function during neuroinflammation. Here, we evaluated Streptococcus agalactiae infected tilapia (Oreochromis niloticus) brain for the expression profile of miRNAs, potential functions and their correlation with genes involved in inflammatory pathways. A total of 1981 miRNAs were identified, including in 486 miRNAs which have homologues in the currently available databases and 1945 novel miRNAs. The expression levels of 547 miRNAs were significantly altered at 6 h-48 h post-bacterial infection, and these miRNAs were therefore classified as differentially expressed tilapia miRNAs. Real-time PCR were implemented for 14 miRNAs co-expressed in five samples, and agreement was confirmed between the high-throughput sequencing and real-time PCR data. For the 486 differentially expressed miRNAs target 41,820 genes. GO and KEGG enrichment analysis revealed that some target genes of miRNAs were grouped mainly into the categories of apoptotic, signal pathwayand immune response. This is the first report of comprehensive identification of teleost miRNAs being differentially regulated in brain in normal conditions relating to bacterial infection.
