Outline of Final Research Achievements

Remote ischemic preconditioning (RIPC) is the phenomenon whereby brief episodes of ischemia-reperfusion applied in distant tissues or organs render the myocardial reperfusion injury. Recent clinical data showed RIPC is effective to contract induced nephropathy. This study evaluated the underlying mechanism on RIPC and found that circulating exosome was important for a mediator of RIPC. The microRNAs in exosomes were changed after RIPC. These finding suggest that further analysis of exosomes may provide novel therapy for contrast induced nephropathy.
