Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. In recent years, researchers are attracted to the use of cell therapy based on stem cell and progenitor cells, which has been a promising strategy for cardiac repair after injury. However, conducted research using intracoronary or intramyocardial transplantation of various types of stem/progenitor cells as a cell suspension showed modest efficiency. ⋯ To overcome these limitations, the concept of the use of multicellular spheroids modeling the natural microenvironment of cells has been proposed, which allows maintaining their viability and therapeutic properties. It is of great interest to use so-called cardial spheroids (cardiospheres) spontaneously forming three-dimensional structures under low-adhesive conditions, consisting of a heterogeneous population of myocardial progenitor cells and extracellular matrix proteins. This review presents data on methods for creating cardiospheres, directed regulation of their properties and reparative potential, as well as the results of preclinical and clinical studies on their use for the treatment of heart diseases.

To evaluate the efficacy of mechanical bacterial lysate on the prevention of infectious exacerbations of chronic obstructive pulmonary disease in patients with frequent exacerbations. ⋯ The results of the study indicate that MBL may be used for the prevention of severe infectious exacerbations of COPD.

A present review is devoted to the current state of the problem of blood pressure variability (BPV) in hemodialysis patients. The BPV classification and clinical significance of BPV metrics are discussed. The results of cohort and randomized studies on the high BPV influence on outcomes in hemodialysis patients, as well as on the possibilities of antihypertensive drugs in the treatment of high BPV in dialysis patients, are presented.

Rebamipide is a mucoprotective drug which was developed in Japan in 1990. The therapeutic effect of rebamipide based on the induction of cyclooxygenase-2 and increasing level of prostaglandins, inhibition of oxygen free radicals production, epidermal growth factor stimulation, vascular endothelial growth factor, nitric oxide, and decreasing of lipid peroxidation and neutrophils migration. The combination of proton pump inhibitors and rebamipide is more effective in relieving of gastroesophageal reflux disease symptoms and reducing recurrence rate of disease. Using rebamipide in the treatment of gastroesophageal reflux disease is justified because this drug has a unique mechanism of action, which eliminating the main stages of pathogenesis of the disease.

Improvement and development of technologies for laboratory and instrumental examination of patients in recent years have greatly facilitated the diagnosis of ischemic myocardial damage. However, a decrease in the rating of cardiovascular diseases is not expected in the short term. This is due to an increase in the life expectancy of the population, general aging of the population and improving diagnostic capabilities and the provision of medical care. ⋯ Full restoration of organs is possible only if the patient is successfully evacuated to the hospital and there are specialists of the appropriate level of experiebce, X-ray surgical equipment with suitable supplies or pharmacological agents, usefull for quickly restoration the patency of the great vessels and normal blood flow. A large number of studies appear on the phenomenon of preconditioning at the present stage of development of fundamental medical science. The purpose of this article is to reveal the possibilities of using molecular markers of the phenomenon of preconditioning in the framework of the early detection of hypoxic conditions, the assessment of their diagnostic use in the clinic and the prevention of hypoxia-associated diseases.
