Diagnostic Value of 4 μg/mL vancomycin screening plate for vancomycin-non-susceptible Staphylococcus aureus:a Meta-analysis / 国际检验医学杂志

Objective To evaluate the diagnostic accuracy of 4 μg/mL vancomycin screening plate (4VA)for vancomycin-non-susceptible Staphylococcus aureus.Methods The diagnosis trials on 4VA for vancomycin-non-susceptible Staphylococcus aureus were searched in the databases such as PubMed(1 966 to Aug.2013),The Cochrane Library(the second phase of 2013),ISI Web of Knowledge(1 980 to Aug.2013),CNKI (1 964 to Aug.2013),VIP (1 989 to Aug.2013)and Wanfang(1 998 to Aug.2013),mean-while the manual.Two reviewers evaluated the quality of the included trials according to the quality assessment of diagnostic accu-racy studies,and then meta-analysis was performed using Meta-Disc 1.4 software.Results A total of 3 trials involving 974 partici-pants were included.The results of meta-analysis showed that the weighted sensitivity,specificity,positive likelihood ratio,negative likelihood ratio and diagnostic odds ratio,were 0.805 [95%CI (0.047 to 0.563)],0.921 [95%CI (0.901 to 0.938)],10.804 [95%CI (5.5 1 1 to 21.181)],0.1 62 [95%CI (0.71 to 1.0)]and 69.721 [95%CI (1 1.740 to 414.06)]respectively.Conclusion 4VA for vancomycin-non-susceptible Staphylococcus aureus has a very high specificity and sensitivity,so 4VA could be used to creening plate (4VA)for vancomycin-non-susceptible Staphylococcus aureus in clinic.

Anti-cervix-cancer effect of the co-immobilization of tumor necrosis factor-alpha and interferon-gamma / 生物医学工程学杂志

To explore the effect of the co-photo-immobilization of Recombinant Human Interferon-r (IFN-gamma) and Recombinant Tumor Necrosis Factor (TNF-alpha) on the Hela cell cultivated in vitro. Co-immobilize the photoactive IFN-gamma and TNF-alpha on the polystyrene membrane; Cultivate the Hela cell on the cell culture polystyrene plate surface and set up the cultivation of the photo-immobilization IFN-gamma+TNF-alpha, Photo-immobilization IFN-gamma, nature (IFN-gamma, TNF-alpha, IFN-gamma+TNF-alpha). After 48 hours, the inhibition effect against Hela cells was studied in vitro by SEM and flow cytometry. It showed that the co-immobilization IFN-gamma+TNF-alpha has a more obvious inhibition effect on the Hela cell. And IFN-gamma can cooperate with TNF-alpha obviously.

Quantitative parameters on nuclear DNA of ovarian mucinous cystadenomatous in differential diagnosis / 中国癌症杂志

Purpose:To study the value of nuclear DNA morphological parameters in differential diagnosis. Methods:Using the cellular image analysis instrument to quantitate nuclear DNA morphological parameters (including area, perimeter, major diameter, equivalent circle diameter and nuclear shape factor) in 38 cases of ovarian mucinous cystadenomatous and 5 normal ovarian epithelial tissue, and to analyze the relationship between histodifferentiation and nuclear morphological. Results:Statistical analysis showed that there were significant differences between the groups ( P 0.05). Conclusions:Nuclear DNA morphological parameters of ovarian mucinous cystadenomatous are useful markers, and may have some significance in pathological diagnosis.
