Discharge dose accurate control method and device applied to cardiac defibrillator

The invention provides a discharge dose accurate control method and device applied to a cardiac defibrillator. The defibrillator automatically sets the minimum electric energy required by defibrillating discharge according to the magnitude of sensed thoracic impedance. The amplitude reference interval value and the normal phase and reverse phase sawtooth wave total number of a dual phase sawtooth pulse discharge waveform are calculated. According to a preset H bridge switch control policy, the electric energy in an energy storage capacitor is used to carry out fast high voltage electric defibrillating on a patient in the form of dual phase sawtooth wave pulse. According to the invention, based on thoracic impedance sensing of the patient and individually customized dual phase sawtooth pulse discharge, defibrillating discharge current which is superposed on a dual phase rectangular wave and is in the form of a sawtooth fine wave is provided for heart in a ventricular fibrillation state; by controlling the normal phase and reverse phase sawtooth wave number, the patient discharge dose is accurately and flexibly controlled, which is conducive to improving the defibrillating discharge individual pertinence and the success rate of once defibrillating; and by reducing the high voltage amplitude, myocardial damage in a defibrillating process is effectively reduced.

Local vascular delivery of adenosine a2a receptor agonists to reduce myocardial injury

A stent or other implantable medical device for the local delivery of a selective adenosine receptor agonist may be utilized to reduce myocardial injury following an acute myocardial infarction. As soon as possible following an acute myocardial infarction a stent or other suitable device comprising and capable of delivering a selective adenosine receptor agonist is positioned in the blood vessel with the occlusion responsible for causing the infarct. Once in position , the stent or other intraluminal device is deployed to remove the occlusion and reestablish blood flow to the specific area, region or tissue volume of the heart. Over a given period of time the selective adenosine receptor agonist elutes from the stent or other device into the downstream coronary blood flow into the hypoxic cardiac tissue for a time sufficient to reduce the level of myocardial injury.

Medical application of CREG1 protein in prevention or treatment of sorafenib-induced myocardial injury

The invention relates to a medical application of E1A activated gene repressor protein, in particular to a medical application of CREG1 protein or an active fragment thereof in prevention and/or treatment of sorafenib-induced myocardial injury and related diseases. Experiments prove that sorafenib intervention causes decline of the heart function of a wild type C57BL/6J mouse, meanwhile, the expression of mRNA and protein of CREG1 gene in myocardial tissue are remarkably reduced, and myocardial injury markers are remarkably increased. Exogenous administration of CREG1 recombinant protein can significantly reduce sorafenib-induced myocardial injury and cardiac dysfunction. The expression of the sorafenib-induced mouse myocardial cell programmed necrosis marker protein is obviously increased, and the death mode is programmed necrosis; exogenous administration of CREG1 recombinant protein can significantly inhibit the occurrence of programmed myocardial cell death induced by sorafenib, and the cardiac function is improved. The CREG1 recombinant protein can be used for preventing or treating myocardial injury and related diseases caused by sorafenib.

Application of NOD signaling pathway induced by abnormal palmitic acid metabolism in diagnosis and prevention of myocardial injury

The invention discloses an application of NOD signaling pathway induced by abnormal palmitic acid metabolism in diagnosis and prevention of myocardial injury, when myocardial gets injured, the level of palmitic acid in body becomes abnormal, the NOD-like receptor signaling pathway is activated to induce inflammation, furthering aggravate myocardial injury. The innovative point of the application is as follows, starting from the above mechanism, applying NLRP3-inhibitor glibenclamide to the prevention of myocardial injury caused by abnormal palmitic acid, myocardial injury can be alleviated byinhibiting the inflammatory response of NOD-like receptor signaling pathway. Meanwhile, finding out the level of palmitic acid in body can diagnose myocardial injury or access the risk of being worsefor patients. The discovery provides heart disease caused by drug toxicity and abnormal lipid metabolism or diagnosis and treatment of diseases in connection with lipid metabolism.
