Aim We retrospectively evaluated the role of neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) as prognostic factors in metastatic non-small-cell lung cancer patients treated with nivolumab. Materials & methods Medical records of 65 patients were reviewed. NLR and LMR were calculated at baseline (t0) and at first radiological tumor assessment (t1). Results At univariate analysis, low NLR or high LMR values at t0 were associated with longer overall survival (p = 0.0001). At multivariate analysis including NLR and LMR at t0 and t1 and their trend, only NLR at t1 (p less then 0.0001) and NLR trend (p less then 0.0001) were significantly associated with overall survival outcomes. selleck chemical Conclusion Our study suggests that NLR value at first tumor assessment or NLR trend could be used as prognostic indicators during nivolumab treatment in metastatic non-small-cell lung cancer.Intestinal mucosal barrier dysfunction is involved in the pathogenesis of inflammatory bowel disease, including ulcerative colitis (UC). Xinhuang tablets (XHTs) have been prescribed for several kinds of inflammatory diseases, including UC, whereas its possible underlying molecular mechanisms had never been explored. Mouse model of UC was constructed by DSS treatment and followed by XHT treatment. Disease activity index, histopathological of colonic tissue, tumor necrosis factor-alpha (TNF-α), and serum amyloid A (SAA) levels in serum were further assessed. The underlying mechanism was further explored by determination of the expression of epithelial tight junction-related protein. XHT administration ameliorated dextran sulfate sodium (DSS)-induced clinical symptoms, colonic histological injury, and decreased the circulating levels of TNF-α and SAA. Moreover, XHT treatment significantly increased the protein levels of zona occludens (ZO)-1, whereas decreased the levels of phosphorylation of Elk-1. In conclusion, this study confirmed the therapeutic effects of XHT treatment on UC in a DSS-induced mouse model, and indicated that by increasing expression of epithelial tight junctions and decreasing phosphorylation of Elk-1 might be one of the underlying mechanisms of XHT treatment on UC.Thioredoxin-interacting protein (TXNIP) plays important roles in the pathogenesis of type 2 diabetes mellitus (T2DM). This study was aimed to investigate the association between T2DM and polymorphisms of TXNIP genes in a Chinese Han population. To our knowledge, there were no studies on this aspect in China. In our research, genotyping was performed by direct sequencing in 161 T2DM patients and 146 healthy controls. The relationships between the genotypes of single nucleotide polymorphism and serum-specific clinical variables were analyzed. TXNIP protein expression was detected by western blotting. We found that the frequencies of G allele, the CG, and CG/GG genotypes of TXNIP rs7212 were all significantly higher in T2DM patients than the controls. G allele, CG, and CG/GG genotypes of rs7212 were associated with a higher risk of T2DM. Furthermore, the CG and CG/GG genotypes of rs7212 in T2DM patients with a longer duration of disease were more frequent compared with the CC genotype diabetes. For rs7212, T2DM patients with higher glucose (GLU) level or/and HbA1c level more frequently carried G allele. In addition, the protein level of TXNIP in the peripheral leukocytes with T2DM was significantly higher than in the controls. Our study indicates that the TXNIP polymorphisms are associated with the susceptibility to T2DM in a Chinese Han population from central China.Pancreatic cancer (PC) is one of the most lethal malignancies with an extremely poor prognosis. In this study, we aim to construct a long noncoding RNA (lncRNA)-based panel biomarker to predict the overall survival of PC patients. The lncRNA expression profiles of PC samples were extracted from The Cancer Genome Atlas (TCGA-PAAD, n = 176) and International Cancer Genome Consortium (PACA-CA, n = 180). We then developed a risk score model according to the lncRNAs expressions from the TCGA-PAAD cohort and further validated it in the PACA-CA cohort. The potential biological functions for the prognostic lncRNAs were investigated using gene set enrichment analysis (GSEA). In the TCGA-PAAD cohort, three lncRNAs (AC009014.3, RP11-48O20.4, and UCA1) were found to be strongly associated with the prognosis of PC. These lncRNAs were integrated to build a three-lncRNA prognostic model that could divide individuals into low- and high-risk groups. Patients of TCGA-PAAD cohort in the high-risk group showed a poorer overall survival than those in the low-risk group (median 17.3 months vs. 30.4 months, log-rank p less then 0.001). Similar results were documented in the PACA-CA cohort (median 15.2 months vs. 21.0 months, log-rank p less then 0.001) and in the stratified analyses by patients' age and TNM stage. In addition, the signature exhibited an independent prognostic power and was significantly correlated with tumor relapse and patients' response to chemotherapy. GSEA indicated that the three-lncRNA signature may be involved in many known biological functions in cancer, especially the epithelial mesenchymal transformation. In conclusion, the identified three-lncRNA signature in our study may serve as a robust and useful prognostic biomarker in PC patients.Continuing rapid advances in science and technology both pose potential risks and offer potential benefits for the effective implementation of the Biological Weapons Convention (BWC). The lack of commonly accepted methods for assessing relevant risks and benefits present significant challenges to building common understandings that could support policy choices. This article argues that qualitative frameworks can provide the basis to structure BWC discussions about potential risks and benefits, reveal areas of agreement and disagreement, and provide a basis for continuing dialogue. It draws on the results of a workshop held in Geneva during the 2019 BWC Meetings of Experts. A diverse group of international experts were given the opportunity to apply 2 qualitative frameworks developed specifically to assess potential biosecurity concerns arising from emerging science and technology to BWC-relevant case examples. Participants discussed how such frameworks might be adapted and put into action to help support the BWC.
