Objective To study the effects of scutellarin on LPS-induced pro-inflammatory cytokine expression in BV2 cells, so as to explore the anti-inflammatory mechanism of scutellarin. Methods The experiment was divided into 5 groups, namely, a normal control group, a model control group (stimulated by LPS), and three Scutellarin treatment groups (0.1, 1, and 100 μg/ml). NF-κB activity was examined by Luciferase Reporter Gene Assay. BV2 cells were treated with LPS; expressions of TNF-α and IL-β mRNA and protein were examined by real-time PCR and Western blotting analysis, respectively. Results Scutellarin treatment greatly inhibited LPS-induced NF-κB activation in pNF-κB 293 cells. The treatment also noticeably inhibited LPS-induced expression of TNF-α and IL-β in BV-2 cells. Conclusion Scutellarin has anti-inflammatory effect, which maybe related to the inhibition of NF-κB-mediated pathway and inhibition of pro-inflammatory cytokine expression.

Objective To detect the mutant prevention concentration (MPC) of macrolide resistant Streptococcus pneumoniae, to amplify the resistance gene of Streptococcus pneumoniae mutants selected in the mutant selection window (MSW), and to investigate the mechanism in the resistance of Streptococcus pneumoniae to macrolides. Methods The Streptococcus pneumoniae strain ATCC49619 was enriched in broth, and the bacterial concentrations were adjusted to 1010 colony forming units per milliliter. The minimal inhibitory concentration (MIC), MIC for 99 % of input cells (MIC99), provisional MPC (MPCpr), and MPC of roxithromycin and azithromycin for Streptococcus pneumoniae were determined by agar plate dilution method. The ermB and mefA of Streptococcus pneumoniae mutants selected in the MSW were obtained by PCR method and sequencing. Results The MPCs of roxithromycin and azithromycin for ATCC49619 were 0.80 ?g/ml and 0.51 ?g/ml, and the MPC/MIC99 were 5.0 and 3.9. The ermB gene was detected in Streptococcus pneumoniae mutants selected in the MSW. Conclusion Adjustment of the drug dose may limit the enrichment of macrolide-resistant Streptococcus pneumoniae mutant. The mechanism in the resistance of Streptococcus pneumonia to macrolides may be associated with ermB genes carried.
