Objective To analyze the effects and recurrence rate of single miconazole and the miconazole plus living preparation of lactobacillus for the treatment of the uncomplicated vulvovaginal candidiasis. Methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2008) MEDLINE (1966 to January 2009); PubMed (1966 to January 2009); EMbase (1966 to January 2009); CNKI (1966 to January 2009), and the Chinese Biomedicine Database (CBM) (1966 to January 2009) to identify randomized controlled trials of single miconazole versus the miconazole plus living preparation of lactobacillus.The quality of the included trials was assessed. RevMan 5 software was used to conduct meta–analysis. Results Eight trials involving 5 156 patients were included in the effect analysis. Meta-analysis showed miconazole plus with living preparation of lactobacillus was better compared with just miconazole (RR=0.96, 95%CI 0.92 to 1.00, Z=2.12, P=0.03; RR=0.92, 95%CI 0.85 to 0.99, Z=2.17, P=0.03).Seven trials involving 4 852 patients were included in recurrence rate analysis. Meta-analysis showed miconazole plus living preparation of lactobacillus had lower recurrence rate compared with single miconazole (RR=3.72, 95%CI 1.94 to 7.13, Z=3.97, Plt;0.000 1; RR=12.85, 95%CI 8.27 to 19.96, Z=11.37, Plt;0.000 01). Conclusion Currently available evidence shows that the effect in the combined group is better, and the recurrence rate is lower.
This study aims to explore the temporal pattern of DNA breaks induced by nanosecond electric pulses (nsEP) in cisplatin-sensitive and cisplatin-resistant human ovarian cancer cells. Human ovarian cancer cells A2780 (cisplatin-sensitive subline) and C30 (cisplatin-resistant subline) were exposed to nsEP. Sham exposed groups were shame exposed to nsEP. Cell viability was determined using CCK-8 assay after 0 h, 4 h, 8 h, 12 h and 24 h, respectively, and the percentage of dead cells was calculated. The DNA break was detected with the alkaline single cell gel electrophoresis (comet assay), and the 75th percentiles of TL (tail length), TM (tail moment) and OTM (Olive tail moment) were measured. Cell viability displayed an early decrease and late increase, with the valley value seen at 8 h. Percentages of cell death and comet-formed in A2780 cells were higher than those in C30 cells (P<0.05) at 8 h, respectively. TL, TM and OTM in C30 cells were less than those in A2780 cells (P<0.05). The percentage of comet-formed correlated with that of cell death in either A2780 (r=0.997, P<0.05) or C30 (r=0.998, P<0.05) cells. DNA breaks induced by nsEP in cisplatin-sensitive cells differred from that in resistant cells, and DNA break resulted in fraction of cell death.
