RESUMEN
Extracorporeal membrane oxygenation (ECMO), a kind of life support technology that can replace lung and heart function, is widely used in critical respiratory and circulatory exhaustion. Because of the serious diseases and the use of interventional catheters, patients receiving ECMO life support are often administrated with broad-spectrum antimicrobial agents, which increase the risk of fungal infection. Fungal infection during ECMO can increase mortality. How to effectively control fungal infection is a thorny problem faced by clinicians. During the treatment of ECMO, the patient's physiological status, ECMO oxygenation membrane, circulation pipeline and other factors may change the pharmacokinetic profiles of antifungal drugs, thereby affect the clinical efficacy of drugs. This artical reviews the pharmacokinetic characteristics of antifungal drugs during ECMO support, in order to provide references for clinical antifungal treatment.
RESUMEN
@#Objective To detect whether the cardiomyocyte-like cells differentiated from human marrow mesenchymal stem cells (hMSCs) could produce action potential (AP). Methods Isolated and cultured hMSCs were induced into cardiomyocyte-like cells with 5-Azacytine in vitro. They were measured for their AP by patch clamp technique, and compared with those of hMSCs of the same generation and beating cardiomyocytes (CMs) derived from 2 day-old SD rats. Results 6/30 cardiomyocyte-like cells produced AP. The CMs produced significant AP, hMSCs appeared no AP, and cardiomyocyte-like cells appeared weak AP. Conclusion The hMSCs manifested the potential to differentiate into CMs in the electrophysiology characteristics following 5-Azacytine induction.
