| 1 | A historical literature review of coronary microvascular obstruction and intra-myocardial hemorrhage as functional/structural phenomena显示文摘The analysis of experimental data demonstrates that platelets and neutrophils are involved in the no-reflow phenomenon,also known as microvascular obstruction(MVO).However,studies performed in the isolated perfused hearts subjected to ischemia/reperfusion(I/R)do not suggest the involvement of microembolization and microthrombi in this phenomenon.The intracoronary administration of alteplase has been found to have no effect on the occurrence of MVO in patients with acute myocardial infarction.Consequently,the major events preceding the appearance of MVO in coronary arteries are independent of microthrombi,platelets,and neutrophils.Endothelial cells appear to be the target where ischemia can disrupt the endothelium-dependent vasodilation of coronary arteries.However,reperfusion triggers more pronounced damage,possibly mediated by pyroptosis.MVO and intra-myocardial hemorrhage contribute to the adverse post-infarction myocardial remodeling.Therefore,pharmacological agents used to treat MVO should prevent endothelial injury and induce relaxation of smooth muscles.Ischemic conditioning protocols have been shown to prevent MVO,with L-type Ca2+channel blockers appearing the most effective in treating MVO. | Leonid N.Maslov Natalia V.Naryzhnaya Sergey V.Popov Alexandr V.Mukhomedzyanov Ivan A.Derkachev Boris K.Kurbatov Andrey V.Krylatov Feng Fu Jianming Pei Vyacheslav V.Ryabov Evgenii V.Vyshlov Svetlana V.Gusakova Alla A.Boshchenko Akpay Sarybaev | 2023 | The Journal of Biomedical Research2023，37，4： | 2 |

| 3 | The effect of an adaptation to hypoxia on cardiac tolerance to ischemia/reperfusion显示文摘The acute myocardial infarction(AMI)and sudden cardiac death(SCD),both associated with acute cardiac ischemia,are one of the leading causes of adult death in economically developed countries.The development of new approaches for the treatment and prevention of AMI and SCD remains the highest priority for medicine.A study on the cardiovascular effects of chronic hypoxia(CH)may contribute to the development of these methods.Chronic hypoxia exerts both positive and adverse effects.The positive effects are the infarct-reducing,vasoprotective,and antiarrhythmic effects,which can lead to the improvement of cardiac contractility in reperfusion.The adverse effects are pulmonary hypertension and right ventricular hypertrophy.This review presents a comprehensive overview of how CH enhances cardiac tolerance to ischemia/reperfusion.It is an in-depth analysis of the published data on the underlying mechanisms,which can lead to future development of the cardioprotective effect of CH.A better understanding of the CH-activated protective signaling pathways may contribute to new therapeutic approaches in an increase of cardiac tolerance to ischemia/reperfusion. | Natalia V.Naryzhnaya Leonid N.Maslov Ivan A.Derkachev Huijie Ma Yi Zhang NRajendra Prasad Nirmal Singh Feng Fu Jianming Pei Akpay Sarybaev Akylbek Sydykov | 2023 | The Journal of Biomedical Research2023，37，4： | 1 |
