The resuts of randomized, double-blind, placebo-controlled, prospective trial in parallel groups of evaluation the efficiency safety and tolerability threefold (once a week) intraarticular injection of Spherogel are discussed in the study. It is estimated of positive effect of this medication to simptoms of gonarthritis: reducing of pain and improvement of functional activity of joint with a good tolerability. This effect continuos for least 3 month.

We tested the hypothesis that simultaneous transgenic overexpression of a select quartet of growth factors activates diverse signaling pathways for mobilization and participation of various stem/progenitor cells for cardiogenesis in the infarcted heart. IGF-1, VEGF, SDF-1α, and HGF plasmids were synthesized and transfected into rat skeletal myoblasts (SM). Overexpression of growth factors in transfected SM (TransSM) was confirmed by reverse transcription PCR, western blotting, and fluorescence immunostaining. The conditioned medium (CM) from TransSM was cytoprotective for cardiomyocytes following H 2O 2 treatment, promoted a higher transwell migration of HUVEC cells and in vitro tube formation. Intramyocardial transplantation of 1.5×10 6 TransSM in a rat model of acute myocardial infarction induced extensive mobilization of stem/progenitor cells into the infarcted heart on day 7 and improved integration of TransSM in the heart compared to NatSM. Extensive neomyogenesis and angiogenesis with resultant attenuation of infarct size and improvement in global heart function was observed at 8 weeks. In conclusion, simultaneous activation of diverse signaling pathways by overexpression of multiple growth factors caused massive mobilization and homing of stem/progenitor cells from peripheral circulation, the bone marrow, and the heart for accelerated repair of the infarcted myocardium.

In the article the clinical case of recurrence of typical atrioventricular nodal reentry tachycardia (AVNRT) in 8 years from the moment of a radiofrequency catheter ablation of slow pathway of atrioventricular junction concerning paroxysmal AVNRT at the patient of 42 years is described.

It is considered the case of severe heart failure in patient with Graves' Disease. Its special feature is the dominance of circulatory decompensation events in clinical picture.

The paper deals with current possibilities of pre-operative therapeutic assessment and the management of patients with concurrent cancer and cardiac diseases.Adequate diagnostics, modern surgery and therapeutic methods in pre- and postoperative period allow to survive 12 months without features of both diseases in 68.4% of patients. 3-5 year survival rate is respectively 25.8-12.9%.
