Detailed Description
The present invention will be described more fully hereinafter in order to facilitate an understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
The experimental procedure, which does not address the specific conditions in the examples below, is generally followed by routine conditions, such as, for example, sambrook et al, molecular cloning: conditions described in the laboratory Manual (New York: cold Spring Harbor Laboratory Press, 1989) or as recommended by the manufacturer. The various chemicals commonly used in the examples are commercially available.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
In order to facilitate an understanding of the present application, the meaning of some terms and expressions in the text of the present invention will be explained below.
As used herein, the term "ischemia" relates to a condition that may occur in any organ or tissue that lacks an oxygen supply and/or a metabolite supply. Ischemia occurs when there is an imbalance between oxygen supply and demand due to inadequate perfusion (i.e., blood supply). The lack of oxygen supply may be caused by thrombosis, the presence of stenotic atherosclerosis, restenosis, anemia, stroke, arterial clotting, vasoconstriction and/or endothelial dysfunction of the microvascular system (Taku Su Bo syndrome).
The term "ischemia reperfusion injury" refers to an injury to an organ or tissue due to insufficient blood supply to the organ or tissue during ischemia prior to the onset of reperfusion (i.e., an ischemic injury is an injury caused by ischemia during the time between the onset of ischemia and the onset of reperfusion).
A typical and pathological manifestation of ischemic injury is the ischemic area becoming pale. In contrast, in reperfusion, non-necrotic ischemic tissue regains its physiological color.
From a biochemical point of view, ischemic injury is characterized by local and systemic changes in pH (acidification) in blood (leukocytes, preferably PBMCs) in ischemic tissue, changes in ATP concentration, increased susceptibility of platelets to activation, and enhanced inflammatory responses in both ischemic tissue localization and the blood system.
Ischemic injury may be caused, for example, by atherosclerosis, thrombosis, thromboembolism, lipid embolism, hemorrhage, stents, surgery, angioplasty, intraoperative bypass surgery, organ transplantation, total ischemia, myocardial infarction, vasoconstriction, microvascular dysfunction, and/or combinations of two or more thereof.
Ischemic injury may involve cell death of muscle cells (preferably by necrosis and/or apoptosis, more preferably by necrosis), injury due to acidification of intracellular pH caused by ischemia, and/or injury due to inflammatory reactions initiated by ischemia and further amplified during reperfusion.
During ischemia, anaerobic metabolism dominates, resulting in a decrease in cell pH. To buffer this accumulation of hydrogen ions, na + /H + The exchanger discharges excess hydrogen ions, which creates a large influx of sodium ions. Calogris (Kalogeris) et al, int Rev Cell Mol biol.2012;298:229-317, which summarize the major pathological events of ischemia and reperfusion components contributing to tissue damage. Ischemia also depletes cellular ATP, inactivating atpase (e.g., na+/k+ atpase), reducing active Ca 2+ Outflow and limiting the re-uptake of calcium by the Endoplasmic Reticulum (ER), thereby producing an intracellular calcium overload. These changes are accompanied by mitochondrial permeability transition (mitochondrial permeability transition, MPT) pore opening that dissipates mitochondrial membrane potential and further impairs ATP production. These changes and thus the extent of tissue damage vary to some extent with the magnitude of the blood supply reduction and the duration of the ischemic period.
Ischemic injury may involve the following symptoms: chest discomfort, shortness of breath, other areas of the upper body, nausea and/or anxiety.
As used herein, the term "reperfusion" relates to restoration of blood flow to ischemic tissue. Although there are clear benefits to reperfusion of blood to ischemic tissue, it is well known that reperfusion itself can lead to a series of adverse reactions that paradoxically harm tissue.
As used herein, the term "reperfusion injury" refers to an injury to an organ or tissue that results when blood supply returns to the organ or tissue after an ischemic period. Thus, reperfusion injury is an injury that is caused during the time between the start of reperfusion and the end of reperfusion (typically, a substantial portion of the injury will be caused during the first few minutes of reperfusion). The underlying mechanism of reperfusion injury is complex, multifactorial, and involves (1) the reintroduction of molecular oxygen upon blood flow remodeling to promote the production of reactive oxygen species (reactiveoxygen species, ROS), (2) calcium overload, (3) the opening of MPT pores, (4) endothelial dysfunction, (5) the appearance of a pre-thrombotic phenotype, and (6) a significant inflammatory response. The lack of oxygen and nutrients in the blood during the ischemia period creates a situation in which the recovery of circulation leads to inflammation and oxidative damage by inducing oxidative stress rather than restoring normal function. Oxidative stress associated with reperfusion may cause damage to the affected tissue or organ. The biochemistry of reperfusion injury is characterized by oxygen depletion during an ischemic event followed by reoxygenation during reperfusion with concomitant production of active oxygen. The damage that occurs with reperfusion is the result of interactions between substances accumulated during ischemia and substances delivered upon reperfusion. The basis of these events is oxidative stress, which is defined as an imbalance between oxygen radicals and endogenous scavenging systems. The result is cell damage and death, which is initially localized, but eventually becomes systemic if the inflammatory response is not examined.
Reperfusion injury is primarily characterized by oxygen bursts and inflammatory response reperfusion injury and consequent tissue damage may occur after revascularization of infarcted (ischemic) tissue. This is associated with an impaired mitochondrial membrane potential, further with the progression of apoptosis, reperfusion-related arrhythmias, cardiac arrest and an overall increase in infarct size caused by ischemia. Thus, the final infarct size (tissue damage) depends on the ischemic damage (tissue damage caused by itself during ischemia) and to a lesser extent on the tissue damage caused by reperfusion.
Reperfusion injury may be caused, for example, by a mechanical event, or by one or more surgical procedures or other therapeutic interventions that restore blood flow to a tissue or organ that has undergone reduced blood flow supply. Such surgical procedures include, for example, coronary artery bypass grafting, coronary angioplasty, and organ grafting. In particular embodiments, reperfusion injury results from treatment of an ischemic process resulting from rupture/erosion of an atherosclerotic plaque and superimposition with a thrombus, thromboembolism, lipid embolism, hemorrhage, stent, surgery, angioplasty, end of a bypass during surgery, organ transplantation, total ischemia, vasoconstriction or microvascular dysfunction, or a combination thereof.
Reperfusion injury may involve oxidative damage, and injury and/or cardiomyocyte death due to an inflammatory response that, although weaker, becomes evident upon reperfusion, that is initiated during ischemia. Preferably, reperfusion injury involves oxidative damage, injury due to inflammatory response and cardiomyocyte death. More preferably, reperfusion injury involves oxidative damage, injury due to inflammatory reactions, and cardiomyocyte death, rather than by intracellular pH acidification.
Reperfusion injury may involve symptoms of palpitations, acute respiratory distress, fatigue, and/or edema.
The embodiment of the invention relates to application of milnacipran or/and pharmaceutical salt of milnacipran in preparation of medicines for preventing or/and treating intestinal ischemia reperfusion injury.
According to the embodiment of the invention, milnacipran and/or the medicinal salt thereof are used for preventing and/or treating intestinal ischemia reperfusion injury, and the effect of the medicament is verified on a constructed classical intestinal ischemia reperfusion model, and the verification result shows that the milnacipran obviously improves intestinal tissue injury induced by intestinal ischemia reperfusion of a mouse, improves the survival rate of the mouse, and has remarkable effect and small side effect.
