AIMS Chondrocyte degeneration is the main cause of osteoarthritis (OA) and increased evidence suggests that miRNAs could have vital roles in the pathology of various cartilage illnesses. miR-1236 has been found to contribute to inflammation in diseases such as pneumonia. However, the exact role of miR-1236 in OA is poorly understood. MATERIALS AND METHODS H&E staining and saffron fixation experiments were employed to determine OA tissues. qRT-PCR and immunohistochemistry were used to detect the expression levels of miR-1236 and PIK3R3. Western blot was performed to detect the expression levels of proteins. Luciferase reporter assays were utilized to investigate the interaction between miR-1236 and PIK3R3. Cell counting assays and AO/EB were used to quantify cell growth and apoptosis. KEY FINDINGS miR-1236 was up-regulated in OA knee cartilage compared to normal cartilage. Up-regulated expression of miR-1236 suppressed cell proliferation as well as induced apoptosis in chondrocytes. Bioinformatics identified PIK3R3 as a target of miR-1236. Co-transfection with miR-1236 and PIK3R3 could reverse cell apoptosis induced by the miR-1236 mimic. SIGNIFICANCE These data enhance our understanding on the role of miR-1236 in OA and identifies miR-1236 as a potential biomarker or possible treatment target within OA. OBJECTIVES Findings during the 2009 pandemic suggest severe maternal infection with pandemic influenza had adverse perinatal health consequences. Limited data exist evaluating the perinatal health effects of severe seasonal influenza and non-influenza infections during pregnancy. METHODS A retrospective cohort of pregnant women from Australia, Canada, Israel, and the United States was established using birth records to identify pregnancies and birth outcomes and hospital and laboratory testing records to identify influenza and non-influenza associated acute respiratory or febrile illness (ARFI) hospitalizations. ARFI hospitalized women were matched to non-hospitalized women (14) by country and season of conception. Log-binomial regression was used to estimate the relative risk (aRR) of preterm birth (PTB), small-for-gestational-age (SGA), and low birthweight (LBW) birth, adjusting for pre-existing medical conditions, maternal age, and parity. RESULTS 950 pregnant women hospitalized with an ARFI were matched with 3,800 non-hospitalized pregnant women. Compared to non-hospitalized women, risk of PTB was greater among women hospitalized with influenza-associated ARFI (aRR 1.57; 95% CI 1.15-2.15) and non-influenza ARFI (aRR 2.78; 95% CI 2.12-3.65). Similar results were observed for LBW; there were no associations with SGA birth. CONCLUSIONS ARFI hospitalization during pregnancy was associated with increased risk of PTB and LBW. OBJECTIVES The study was aimed at investigating the characteristics of peripheral blood lymphocyte subsets and serum cytokines in children with 2019 novel coronavirus (2019-nCoV) pneumonia. METHODS Children with 2019-nCoV pneumonia or with respiratory syncytial virus (RSV) pneumonia were included. Data including lymphocyte subsets and serum cytokines were collected and analyzed. RESULTS 56 patients were included in the study, 40 children with 2019-nCoV pneumonia and 16 children with RSV pneumonia. Compared with children with RSV pneumonia, patients with 2019-nCoV pneumonia had higher count of CD3+8+ lymphocyte, higher percentages of CD3+, CD3+8+ lymphocytes and a lower percentage of CD19+ lymphocyte. The serum IL-10 level was significantly higher in children with RSV pneumonia. One 2019-nCoV pneumonia child who was with an obvious increase of IL-10 developed severe pneumonia. CONCLUSIONS Immune response played a very important role in the development of 2019-nCoV pneumonia. The effective CD8+ T cell response might influence the severity of 2019-nCoV pneumonia. The adaptable change in IL-10 level might contribute to the relatively mild pneumonia symptoms in children with 2019-nCoV pneumonia and bacterial co-infection might be a risk factor of severe 2019-nCoV pneumonia. OBJECTIVES This study sought to more fully elucidate the age-related trends in influenza mortality with a secondary goal of uncovering implications for treatment and prevention. METHODS In this retrospective cohort analysis of data from the Nationwide Readmission Database, patients with influenza as a primary or secondary discharge diagnosis were separated into three age groups 55,638 adults aged 20-64, 36,862 older adults aged 65-79, and 41,806 octogenarians aged ≧80. Propensity score (PS) weighting was performed to isolate age from other baseline differences. Crude and PS-weighted hazard ratios (HR) were calculated from the in-hospital all-cause 30-day mortality rate. Admission threshold bias was minimized by comparison of influenza with bacterial pneumonia mortality. RESULTS Adults aged 20-64 experienced higher in-hospital 30-day mortality compared to older adults aged 65-79 (HR 0.66; 95%CI 0.55-0.79). Octogenarians had the highest mortality rate, but this was statistically insignificant compared to the adult cohort (HR 1.09; 95%CI 0.94-1.27). This trend was not explained by admission threshold bias the 30-day mortality rate due to in-hospital bacterial pneumonia increased consistently with age (older adult HR 1.45; 95%CI 1.32-1.59; octogenarian HR 1.99; 95%CI 1.82-2.18). CONCLUSIONS Adults aged 20-64 and octogenarians were more likely to suffer from all-cause 30-day mortality during influenza hospitalization compared to older adults aged 65-79. These data emphasize the importance of prevention and suggest the need for more tailored treatment interventions based on risk stratification that includes age. Selleck U0126 Research shows that endothelin (ET)-traps are a potential therapy for diabetes. Given that type 1 diabetes mellitus (T1DM) is an autoimmune disorder, ET-traps could also have an efficacious, therapeutic effect on other autoimmune diseases associated with pathologically elevated ET-1. Here, we describe those different autoimmune diseases that might benefit from a tool such as ET-traps, which potently sequester these elevated levels of ET-1. We also discuss the current use of ET receptor (ETR) antagonists and the associated adverse effects, and how ET-traps are associated with no toxicity and potentially offer a superior alternative. ET-traps could be used against different autoimmune diseases and, therefore, are a novel therapeutic tool for such conditions.
