Corticosteroid therapy and delayed NAI treatment were associated with prolonged A(H7N9) RNA shedding. NAI combination therapy and double-dose oseltamivir treatment were not associated with a reduced A(H7N9) shedding duration as compared to standard-dose oseltamivir.
Cisplatin (DDP)-based chemotherapy is a standard strategy for lung cancer, while chemoresistance remains a major therapeutic challenge. Recent evidence highlights the crucial regulatory roles of long non-coding RNAs (lncRNA) in tumor biology. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has important roles in regulating the proliferation, invasion and migration of lung cancer cell. High MALAT1 expression in lung cancer was related to poorer clinicopathologic features in this study. MALAT1 knockdown alone was sufficient to amplify DDP-induced repression of cell viability. MALAT1 knockdown could also sensitized DDP-resistant lung cancer cells (A549/DDP and H1299/DDP) to DDP. Further assays indicated that MALAT1 acted as a competing endogenous RNA to upregulate SOX9 expression by sponging miR-101 in DDP-resistant cancer cells, through Wnt signaling pathway. Moreover, SOX9 could bind to the promoter of MALAT1 to activate its transcription. Taken together, MALAT1, miR-101 and SOX9 form a feedback loop to enhance the chemo-resistance of lung cancer cell to DDP; this MALAT1-miR-101-SOX9 feedback loop plays an important role in the chemo-resistance of lung cancer cell to DDP and may serve as a potential target for cancer treatment.
Lymphocyte to monocyte ratio (LMR) has shown prognostic value in different types of cancer. This study assessed the prognostic performance of LMR in early-stage non-small cell lung cancer (NSCLC) patients and investigated the influence of LMR on the treatment response in patients receiving first-line platinum-based chemotherapy. Four hundred eighty-eight NSCLC patients and 500 healthy donors were enrolled in this study. The cutoff value for LMR was chosen by receiver operating characteristic curve analysis. The prognostic significance of markers was assessed by univariate and multivariate Cox regression models. The median overall survival was 43 months, and the median progression-free survival was 38 months. LMR was associated with disease status and the treatment response of first-line platinum-based chemotherapy. Multivariate analysis showed that LMR was an independent prognostic factor for both overall survival (hazard ratio = 1.53, 95 % confidence interval = 1.09-2.14, P = 0.015) and progression-free survival (hazard ratio = 1.20, 95 % confidence interval = 1.02-1.67, P = 0.028). Furthermore, integration of LMR into a prognostic model including TNM stage, tumor status, chemotherapy, and histological type generated a nomogram, which predicted accurately overall survival for NSCLC patients. Decreased LMR may be a potential biomarker of disease status, worse response to first-line platinum-based chemotherapy, and worse survival for NSCLC patients. A prospective study is warranted for further validation of our findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
