ABSTRACT
Objective To compare the newer antifungal agents micafungin and voriconazole for prophylaxis effects on the clinical outcomes.Methods We electronically searched the database of Cochrane Central Register of Controlled Trials,Pubmed,EMbase,China Biology Medicine (CBM),China National Knowledge Infrastructure(CNKI),and relevant database articles (1996.01-2014.12).Comparative studies were carried out on proved fungal infections,mortality,and adverse effects.Meta-analysis was performed by Review Manager 5.3 software.Results We found 1 564 records and 16 studies totaling 4 234patients included in analyses.Pooled comparisons of studies found that antifungal prophylaxis with the new agents did reduce the incidence of invasive fungal infections and transplant related mortality than fluconazole or itraconazole [OR =0.41 (0.21 ～ 0.80) and OR =0.40 (0.24 ～ 0.66),respectively,P ＜ 0.01].Voriconazole had higher rates of liver dysfunction,lower gastrointestinal side effects over fluconazole,and lower rates of nephrotoxic effects than amphotericin B.Voriconazole had significant decrease in adverse events requiring drug discontinuation compared to itraconazole [OR =0.43 (0.27 ～ 0.68),P ＜ 0.01].Conclusions This analysis indicated the 2 agents appear to be well tolerated with manageable side effects and beneficial in the prophylaxis of invasive fungal infection (IFI).
ABSTRACT
Objective To establish a multidrug resistance cell line of human bladder tumor and study its characteristics and mechanism of muhidrug resistance. Methods Human bladder tumor cell line T24 was induced to muhidrug resistance cell line T24/ADM by intermittent administration of high dose ADM. The multidrug resistance to multianticancer agents of the ceils was evaluated by MTT assay; the expression of MDR gene was assessed by RT-PCR and P-gp expression was determined by flow cytometry. Results T24/ ADM resisted to many anti-tumor agents, and its IC50 of ADM was 16.3 times higher than that of T24. Significant overexpression of MDR gene and p-gp of the multidrug resistant cells were detected. Conclusion T24/ADM is a human muhidrug-resistant cell line, and it's drug resistance relates to the overexpression of MDR gene and p-gp.
