OBJECTIVE:To systematically review the efficacy and safety of Magnesium isoglycyrrhizinate injection versus 4 comnon medicines in the treatment of drug-induced liver damage,and to provide evidence-based reference for clinic treatment. METHODS:Retrieved from PubMed,EMBase,Cochrane Library,CBM,CJFD,Wanfang Database and VIP Database,random-ized controlled trials (RCT) about Magnesium isoglycyrrhizinate injection versus other medicines in the treatment of drug-induced liver damage were enrolled. Meta-analysis was performed by using Rev Man 5.3 software after literature selection,data extract and quality assessment. RESULTS:A total of 13 RCTs were included,involving 1 093 patients. Results of Meta-analysis showed clini-cal effective in magnesium isoglycyrrhizinate group was significantly higher than tiopronin group[RD=0.29,95%CI(0.17,0.42), P<0.001] and diammonium glycyrrhizinate group [RD=0.07,95%CI(0.01,0.12),P=0.02],compared with glutathione group and compound ammonium glycyrrhetate group,there were no significant differences ;incidence of adverse reactions in magnesium iso-glycyrrhizinate group was significantly lower than diammonium glycyrrhizinate group [RD=-0.07,95%CI(-0.11,-0.03),P<0.001] and compound ammonium glycyrrhetate group[RD=-0.21,95%CI(-0.38,-0.04),P=0.02],compared with triopro-nin group and glutathione group,there were no significant differences among 3 groups. CONCLUSIONS:Magnesium isoglycyrrhiz-inate injection has better efficacy and safety than other 4 commons hepatoprotective medicines in the treatment of drug-induced liver damage. Due to the limit of methodological quality,more large-scale and long-term follow-up studies with strict designed are need-ed for the further verification of the conclusion.

Aspergillus fumigatus is an opportunistic pathogenic fungus transmitted through the air. It targets the the lungs of immunocompromised patients and can cause severe invasive aspergillosis. Zinc, an essential trace element for microbial growth, is required by all fungi, including Aspergillus fumigatus. Some studies have shown a direct correlation between the virulence of fungi within the host and the uptake of zinc by them. However, zinc in the human body mostly binds to zinc-binding proteins, resulting in ion concentrations in the host′s tissue microenvironment much lower than the optimal growth concentration for fungi. There are several zinc transport proteins in Aspergillus fumigatus, enabling it to efficiently absorb zinc even in the condition of zinc deficiency. These proteins also protect the cells of Aspergillus fumigatu from the damage caused by excessive zinc. This article is to provide a comprehensive overview of the roles of zinc homeostasis regulation in the growth, development and virulence of Aspergillus fumigatus as well as the related genes, summarize the current research status of genes regulating zinc levels in Aspergillus fumigatus and investigate whether interference with zinc homeostasis in Aspergillus fumigatus will be a new generation of adjunctive therapy for invasive aspergillosis or antifungal strategy.
