Ventricular arrhythmia (VA) is often secondary to acute myocardial infarction (AMI) and other organic heart disease .Many researches have indicated that myocardial cell injury , ventricular remodeling ,abnormalities of neurohumoral regulation and ion channel etc .after AMI can lead to cardiac electrophysiological remodeling and in‐duce VA .In recent years ,researches have found that more and more inflammatory factors are involved in above －mentioned series of pathological changes ,and possess important relationship with occurrence and development of VA.The present article made a review on domestic and foreign related literature .

Objective To describe the CSP genotypic profile in clinical isolates of Aspergillus fumigates from different regions of China,and to investigate if there is a difference in antifungal susceptibility among A.fumigates of different CSP genotypes and from different regions.Methods Totally,112 A.fumigates strains clinically isolated from Fujian,Shanghai,Hebei and Beijing were included in this study,and identified according to macro-and micro-morphological characters,growth temperature and β-tubulin sequence.Classic A.fumigatus strains were typed according to CSP gene sequence.The minimal inhibitory concentrations (MICs) of voriconazole,itraconazole and amphotericin B to A.fumigates were determined in accordance with the National Committee for Clinical Laboratory Standards (NCCLS) M38-A protocol.Results All the strains were identified as classic A.fumigates,and fall into 11 CSP genotypes.The most common genotypes were t04A (n =32),t03 (n =17) and t01 (n =24) in all the strains,tl0,t04A and t01 in Fujian,t04A and t01 in Shanghai,t01,t03 and t04A in Hebei,t02,t04A,t01and t03 in Beijing.One A.fumigatus strain was identified as a new CSP type t25 in Fujian,which showed no obvious difference in morphology,growth rate or appropriate growth temperature from the other CSP genotypes of A.fumigatus strains.No statistical difference was found in the susceptibility to amphotericin B,itraconazole or fluconazole among different genotypes of A.fumigates,whereas the MICs of itraconazole were significantly lower in A.fumigates isolates from Fujian than in those from the other three regions.Conclusions The CSP genotypic profile of A.fumigates varies in clinical isolates from different regions.No significant difference is observed in the susceptibility to amphotericin B,itraconazole or fluconazole among different CSP genotypes of A.fumigates,but the susceptibility to itraconazole is somewhat different between A.fumigates strains from different regions.
