BACKGROUND: Associations between cytotoxic T lymphocyte antigen-4 (CTLA-4) +49A/G polymorphism and cancer risk are inconclusive. We performed this meta-analysis to derive a more precise estimation of the relationship. METHODS: A comprehensive literature search was performed using electronic databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association. RESULTS: A total of 16,358 cases and 19,737 controls from 46 studies were included. Overall, significant association between CTLA-4 +49A/G polymorphism and cancer risk was observed in all genetic models (G vs. A: OR=0.88, 95%CI=0.83-0.93, P-H=0.000; GA vs. AA: OR=0.87, 95%CI=0.79-0.97, P-H=0.000; GG vs. AA: OR=0.75, 95%CI= 0.65-0.86, P-H=0.000; GG vs. GA+AA: OR=0.84, 95%CI=0.79-0.91, P-H=0.001; GG+GA vs. AA: OR=0.83, 95%CI=0.74-0.92, P-H=0.000). Stratified analysis by cancer type revealed that the CTLA-4+49A/G polymorphism is associated with the decreased risk of cervical cancer, breast cancer, lung cancer, HCC. Further subgroup analysis by ethnicity indicated that there was a statistically decreased cancer risk in Asian population. CONCLUSION: This meta-analysis suggests that CTLA-4+49A/G polymorphism is associated with cancer risk, especially in Asian population. © 2014 - IOS Press and the authors. All rights reserved.

MicroRNAs (miRNAs) play a pivotal role in cancer progression and development, representing novel therapeutic tools for cancer therapy. Forkhead box Q1 (FOXQ1) functions as an oncogene in various cancer types. However, the functional significance of FOXQ1 in cervical cancer remains unknown. In this study, we investigated the biological function of FOXQ1 in cervical cancer and tested whether or not FOXQ1 can be targeted and regulated by specific miRNAs. We found that FOXQ1 was highly expressed in cervical cancer cell lines. Knockdown of FOXQ1 by small interfering RNA (siRNA) significantly suppressed the proliferation and epithelial-mesenchymal transition (EMT) of cervical cancer cells. FOXQ1 was predicted as a target gene of microRNA-506 (miR-506), and this prediction was validated by dual-luciferase reporter assay. Quantitative real-time PCR and western blot analyses demonstrated that mRNA and protein expression was negatively regulated by miR-506. The expression of miR-506 was downregulated in cervical cancer tissues, and miR-506 expression was inversely correlated with FOXQ1 expression in cervical cancer. The overexpression of miR-506 dramatically suppressed the proliferation and EMT of cervical cancer cells that mimicked the suppression of FOXO1 siRNA. Furthermore, the restoration of FOXQ1 expression significantly reversed the inhibitory effect of miR-506. Overall, our study demonstrated that miR-506 inhibited the proliferation and EMT of cervical cancer cells by targeting FOXQ1 and provided evidence that the miR-506/FOXQ1 axis plays an important role in the pathogenesis of cervical cancer, representing potential molecular targets for the development of anticancer agents for cervical cancer treatment.

Human laryngeal papilloma (LP) is a human papillomavirus-induced hyperplastic tumor of the respiratory tract, which is characterized by rapid growth and apoptosis resistance. Isoflurane (ISO) inhibits proliferation and elicits apoptosis in cancer cells. The results of the present study found that the mRNA and protein levels of cyclooxygenase-2 (COX2) were higher in LP tissues than in normal laryngeal samples, and prostaglandin E2 (PGE2) production was increased in LP cells, as determined by quantitative polymerase chain reaction, western blot and radioimmunoassay analyses. Notably, the increase in COX2 and PGE2 levels was significantly abrogated in the ISO-treated LP cells. The inhibitory effects of ISO on COX2 expression and activity depended on the inactivation of p38 mitogen-activated protein kinase (MAPK) in LP cells. By inhibiting the COX2 activity of LP cells, ISO treatment markedly suppressed cell viability and proliferation, as determined using Cell Counting Kit-8, flow cytometry and 5-ethynyl-20-deoxyuridine incorporation assays. Furthermore, ISO treatment promoted cell apoptosis, as demonstrated by flow cytometry, nucleosomal fragmentation and caspase-3 activity assays. Collectively, the present results suggest that COX2 is critical in the progression of LP, and ISO is a potential agent for LP therapy by impeding p38 MAPK/COX2 signaling. © 2016, Spandidos Publications.

The effect of glucocorticoid on cytokines Toll-like receptor (TLR)9 and TLR7 in peripheral blood of patients with uveitis was explored. Forty-six patients with uveitis admitted to our hospital from April 2014 to April 2015 were selected as the research observational group. Thirty-five able-bodied individuals in the same period were selected as the control group. To treat uveitis, the observational group was injected with glucocorticoid (1-2 mg/kg/day) daily, while the control group did not receive any treatment. The quantity of expression of peripheral blood cytokines TLR9 and TLR7 were detected by the methods of fluorescence quantitative PCR, enzyme-linked immunosorbent assay and western blotting. The content of peripheral blood TLR9 and TLR7 (0.210.01, 0.190.01) decreased significantly (P<0.05) in observational group after glucocorticoid treatment. Compared with data of control group (0.210.01, 0.190.01), TLR9 and TLR7 content in peripheral blood after glucocorticoid treatment on the patients with uveitis from observation group (0.190.01, 0.170.01) did not show any significant difference, for correlation between TLR9 and TLR7 in observation group before and after treatment. It was observed that the cytokine content of TLR9 was associated with TLR7 positively (r=0.653, P=0.012). In conclusion, glucocorticoid can improve uveitis by reducing the content of cytokines TLR9 and TLR7 in peripheral blood.

The chemical bonded cellulose acetylsalicylate chiral stationary phase (CSP1) was obtained by fixing cellulose derivative on silica gel with beta-(3, 4-epoxycyclohexyl) ethyl trimethoxy silane as space arm. The resolution mechanism and feasibility of CSP1 were studied by comparing CSP1 with coated chiral stationary phase prepared by cellulose acetylsalicylate. The role of cyclohexyl group in the space arm was also verified by comparing CSP1 with CSP2 which had no cyclohexyl group in the space arm. Based on the chromatographic results, the immobilized chiral stationary phase exhibited better chiral resolving abilities than coated stationary phase for imidazoles. It is due to, on the one hand, more types of mobile phases used, on the other hand, the modified cellulose by cyclohexyl group.

Polymorphisms in microRNA (miR) genes and their target sites are a distinct classification of variation in the human genome, which are rapidly being identified and investigated in human cancer. A polymorphism in the miR-196a-2 locus has demonstrated significant associations with various types of cancer, including lung, breast, esophageal and gastric tumors. However, miR-196a-2 has not been fully explored in ovarian cancer, which shares similar biological characteristics with other types of cancer. Therefore, the present study aimed to elucidate the association between a single nucleotide polymorphism (SNP) in the mature sequence of miR-196a-2 (rs11614913, T/C) and the clinical features of 479 Chinese patients with epithelial ovarian cancer (EOC). In addition, the biological significance of this polymorphism was investigated in the OVCAR3 ovarian cancer cell line. Risk association was evaluated in 479 cases of EOC patients and 431 controls. SNPs were analyzed by using polymerase chain reaction based restriction fragment length polymorphism assay. miR-196a expression was evaluated with reverse transcription polymerase chain reaction. The influence of miR-196a-2 rs11614913 T/C on EOC cell migration and invasion ability was further investigated

This study aims to investigate the risk factors for neonatal nosocomial enteric infection (NNEI) and the effect of intervention with BIFICO.Between May 2013 and June 2015, 215 neonates admitted to our institution were randomly divided into the study group and the control group, 47 for each group. Patients in the study group were treated for primary diseases combined with the oral admission of BIFICO, whereas patients in the control group were treated for primary disease alone. Statistical analysis was performed to obtain the occurrence of enteric infection and univariate, as well as multivariate analysis of clinical data, were performed to investigate the underlying risk factors.Univariate and multivariate analysis of variance showed that gestational age, birth weight, length of hospital stay, invasive procedures and underlying diseases were risk factors affecting NNEI. The occurrence of NNEI in the study group was significantly lower than that in the control group [17.02% (8/47) vs. 29.79% (14/47), X2 = 19.394, p = 0.004].Preterm infant, low-birth-weight infant, length of hospital stay, invasive procedures and comorbidity are independent risk factors for NNEI. Prophylactic therapy with BIFICO can effectively decrease the occurrence of infections and can be widely used in clinical practice.
