    ABSTRACT: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common health problem in the world. However, its etiology remains unclear. Recent researches have hypothesized that Staphylococcus aureus (SA) exotoxins which act as superantigens might be associated with inflammatory mucosal changes seen in CRSwNP. The objective of this study is to evaluate the relationship between Staphylococcus aureus superantigens and CRSwNP. PubMed, MEDLINE, EMBASE, Cochrane Library and CNKI were searched to collect the case-control studies on the relationship between SA superantigens and CRSwNP from the date of establishment of the databases to May 2013. The extracted data were analyzed by RevMan 5.0. The main outcome measures were SA culture-positive rate, the detection rate of SA superantigens and its specific IgE. Twelve studies including 340 cases and 178 controls were selected. The results showed that SA culture-positive rate in the CRSwNP group was significantly higher than that in the control group (OR 4.85, 95 % CI 1.80-13.05, P = 0.002), the detection rate of SA superantigens and its specific IgE in the CRSwNP group were both significantly higher than that in the control group (OR 12.07, 95 % CI 4.57-31.90, P < 0.00001; OR 17.03, 95 % CI 5.43-53.39, P < 0.00001, respectively) and the CD4(+) T cell counts and Lund-Mackay CT scores were statistically higher in the IgE-positive group than in the IgE-negative group (MD 16.26, 95 % CI 4.86-27.67, P = 0.005, MD 2.43, 95 % CI 0.39-4.48, P = 0.02, respectively). However, the eosinophil and CD8(+) T cell counts showed no difference between IgE-positive group and -negative group. This meta-analysis indicated that the SA superantigens may be a risk factor for CRSwNP, and the presence of SA superantigen is related to the disease severity of CRSwNP.

    ABSTRACT: Objective: To evaluate the relationship between bacterial biofilm (BBF) and chronic rhinosinusitis (CRS). Methods: The database on line was searched to collect the studies on BBF and CRS. The method of meta analysis was used to analyze the data of suitable studies. Results: Fourteen studies were included. System evaluation indicated that the BBF detection rate in CRS group was significantly higher than that in the control group (OR = 17.01, P < 0.01), and the nasal surgery's rate of BBF positive group was significantly higher than the negative group (OR = 3.99, P < 0.01). Preoperative Lund-Kennedy endoscopic score, Lund-MacKay CT score, symptom severity score, postoperative Lund-Kennedy score after six months showed no difference between BBF positive group and negative group. Conclusion: The presence of BBF is related to the pathogenesis of CRS and the history of nasal surgery.

    ABSTRACT: The Notch signaling pathway plays an important role in the proliferation and differentiation of cells. Although recent studies have shown that Notch plays a role in the mechanisms of cisplatin resistance, the mechanism by which Notch plays roles in intrinsic or acquired cisplatin resistance remains unclear. In the present study, poorly differentiated nasopharyngeal carcinoma cells were treated with a γ-secretase inhibitor (DAPT), which led to a decrease in the Notch intracellular domain and inhibition of Notch signaling. Treatment was not sufficient to induce pronounced apoptosis of CNE-2 cells, but did result in the down-regulation of the P-glycoprotein and ERCC1 protein. In contrast, the combined treatment of DAPT and cisplatin induced substantial cell apoptosis compared to cisplatin treatment alone.

    ABSTRACT: RNA interference (RNAi) is an evolutionary conserved mechanism for specific gene silencing. There are currently numerous cancer therapy clinical trials based on RNAi technology. Using an adenoviral system as a delivery mediator of RNAi, we investigated the therapeutic effects of targeting three genes simultaneously in vitro and in vivo. In this study, we constructed an recombinant adenoviral shRNA expression system as Adv-pEGFP-shVEGF-shTERT-shBcl-xl for multi-genes silencing. Our results showed that the adenoviral vector can achieve above 90% of transfection efficiency and induced obvious apoptosis in CNE-2 cell both in vitro and in vivo compared with targeting the TERT alone or controlled group.
