Neuroblastoma (NB) is one of the most common childhood tumors that is associated with a poor prognosis.  https://www.selleckchem.com/products/VX-770.html  Recently, immunotherapy has been recognized as an effective strategy in the treatment of NB patients. In this study, an immune-related gene pair (IRGP) signature was established for predicting the prognosis of NB patients.
 
  The Treehouse Childhood Cancer Initiative dataset and the Gene Expression Omnibus (GEO) were included in this study, as the training set and testing set, respectively. Immune-related genes retrieved from the ImmPort database were used to construct the prognostic model. Least absolute shrinkage and selection operator (LASSO) regression was used to develop the prognostic signature. Kaplan-Meier survival curves and the log-rank test were used to compare the differences between high and low immune risk scores groups. Immune infiltration analysis was estimated using TIMER, quanTIseq, and MCP-counter algorithms. The Tumor ImmunoPhenotype (TIP) pipeline was used for cancer-immunity cycle studies.
 
  We identified an IRGP model that was significantly correlated with survival rates and the immune risk score was calculated for each sample. The low immune risk group had significantly better prognostic outcome compared with the high immune risk group. Besides, age, MYCN status, histology, Children's Oncology Group (COG) risk, mitosis-karyorrhexis index (MKI), and immune risk scores were found to be independent prognostic factors. Moreover, the low immune risk group showed a negative correlation with the immune cell infiltration, which may activate the anti-cancer immune response.
 
  This prognostic immune signature based on IRGP reflects the link between the NB patient outcome and immune infiltration, and provides new insights into the prediction of prognosis in NB.

IL-6 is known to be modulated by Vitamin D, and there is preliminary evidence that deficiency of this vitamin is linked to poorer outcomes. To identify whether IL-6 levels prior to infection might predict outcome, early data on COVID-19 mortality from Italy and the UK were compared with previously published results of mean IL-6 levels from these countries as well as from the USA. There was a highly significant correlation (r = 0.9883; p = 0.00025) between age-stratified mortality rates and IL-6 levels from previously published data on healthy individuals. To determine whether Vitamin D may be beneficial at lowering IL-6 levels in patients, a limited analysis of trials examining the relationship between these entities published since 2015 was undertaken. Eight out of 11 studies described a significant lowering effect of Vitamin D on IL-6. Given that IL-6 likely facilitates viral cell entry and replication, levels prior to infection may predict mortality. This provides a rationale for prophylactic and therapeutic measures directed at lowering IL-6, including Vitamin D prescription.Alcohol-induced liver injury is characterized by abnormal liver dysfunction and excessive inflammation response. Recent years a wealth of data have been yielded indicating that EtOH (ethyl alcohol)-induced macrophage activation along with liver inflammation plays a dominating role in the progression of alcohol-induced liver injury. Here we found high expression of NLRP12 (Nucleotide-binding oligomerization domain protein 12, which is generally considered to be a negative regulator of inflammatory response) in EtOH-fed mouse liver tissue, primary Kupffer cells and EtOH-induced RAW264.7 cells. Additionally, overexpression of NLRP12 following Ad (adenovirus)-NLRP12-EGFP contributed to the attenuation of steatosis and inflammation in EtOH-fed mice model and EtOH-primed RAW264.7 cells. In parallel, Knockdown of NLRP12 aggravated the inflammatory response in RAW264.7 cells triggered by EtOH. Meanwhile, after administration of overexpression or inhibition of NLRP12 expression in vitro, the expression of phosphorylated protein of NF-kB signaling pathway was significantly affected. After increasing or decreasing the expression of NLRP12 in RAW264.7 cells, AML-12 cells were cultured with the supernatant of RAW264.7 cells stimulated by EtOH, and the percent of apoptosis ratio of AML-12 cells was remarkably altered. The study suggested that reduced inflammatory response induced by NLRP12-mediated inhibition of NF-kB pathway participated in the decrease of hepatocyte apoptosis in alcohol-induced liver injury. Collectively, these findings suggested the significance of NLRP12-mediated macrophage activation in alcohol-induced liver injury.Phosphodiesterase-4 inhibitors (PDE4) are of great interest for the treatment of airway inflammatory diseases due to its broad anti-inflammatory effects. Roflumilast is a selective PDE4 inhibitor that inhibits pulmonary and systemic inflammation and rallies symptoms in airway diseases. Asthma and COPD are common chronic airway inflammatory diseases having incompletely illustrious pathophysiology and clinical manifestations. Recently, the condition called Asthma- COPD Overlap (ACO) has been evolved having the overlapping symptoms of both diseases. The newly discovered PDE4 inhibitor, roflumilast has exposed its potential in the treatment of Asthma, COPD and ACOS. Its mechanism of action in airway inflammatory diseases are said to be exerts by elevating intracellular cAMP and shows its anti-inflammatory action. Roflumilast, a promising therapeutic approach in inflammatory airway diseases, has many significant outcomes. In this review, we have provided various promising clinical evidences of roflumilast in COPD and asthma. However, there is no published clinical evidence to date for the role of roflumilast in ACOS. Nevertheless, there are therapeutic mechanisms that provide a reference for clinical application for ACOS.
