Year: 2019, volume 15 Issue: №2 Pages: 379-38
Heading: Physiology and Pathophysiology Article type: Original article
Authors: Popykhova E.B., Ivanov A.N., Stepanova T.V., Pronina E.A., Lagutina D.D.
Organization: Saratov State Medical University
Summary:

The purpose of this work is to study the relationship of carbohydrate metabolism disorders and markers of endo-thelial dysfunction in animals with absolute insulin defciency at biostimulation by autotransplantation of the skin fap. Material and Methods. The study was conducted on 60 male white outbred rats, which were divided into: an intact control group, a two comparative and an experimental group. In animals of the comparison group, alloxan diabetes mellitus (DM) was caused, in rats from the experimental group, an autotransplantation of the skin fap was performed against the background of developed alloxan diabetes. The levels of glycated hemoglobin (HbA1c), glucose, C-reactive protein (CRP) and vascular endothelial growth factor (VEGF) were determined. Results. Autotransplantation of the skin fap causes a normalization of the glycemic profle in animals of the experimental group, and also reduces subclinical infammation caused by hyperglycemia and stabilizes the expression of VEGF.Diabetes causes an increase in HbA1c by 69 % and CRP by 11 %, while аutotransplantation of the skin fap leads to a decrease in the concentration of HbA1c by 28 % and CRP by 7 %. Conclusion. Autotransplantation of the skin fap reduces the risk of microcirculatory disorders due to hyperglycemia and chronic subclinical infammation.

Heading: Physiology and Pathophysiology Article type: Original article
Authors: Morrison V.V., Bozhedomov A.Yu., Morrison A.V.
Organization: Russian State Medical University, Saratov State Medical University
Summary:

Objective: to estimate the level of markers of endothelial dysfunction in burn injury of various severities. Material and Methods. 57 patients were included in the study. The level of vascular endothelial growth factor (VEGF), endothe-lin, nitric oxide metabolites (NO), and the amount of circulating desquamated endothelial cells were determined in the dynamics of burn injury development. Results. In burn injury there was an increased amount of endothelial dysfunction markers in blood, which is highly expressed on the 7-15th day. Moreover on the 7th day in case of severe and extremely severe burn injury the level of VEGF was increased over 50 times while the amount of endothelin, nitric oxide metabolites and circulating desquamated endothelial cells becomes higher in 3–5 times. Conclusion. The research outcomes have proved the damage of endothelial lining in burn injury.

Objective: to study the efect of light desynchronosis on behavioral reactions and cognitive functions of white male rats. Material and Methods. The study was conducted on 36 intact non-pedigree white male rats, which were divided into 2 groups: experimental and control. Animals were exposed to artifcial illumination 24 hours a day provided by the fuorescent lamp of 60 kW capacity. The same animals of the experimental group on the 10th, 21st and 30th days were tested in the installations «Dark-light camera» and «Open feld». Results. On the 10th day of intensive light deprivation, the indicators refecting the research-orientation activity reached the maximum values, which indicated the development of stress damage to the animal organism.

Optimization of the process of creating models of human blood vessels

Year: 2019, volume 15 Issue: №2 Pages: 353-357
Heading: Human anatomy Article type: Original article
Authors: Dol A.V., Ivanov D.V., Fomkina O.A.
Organization: Saratov National Research University n.a. N. G. Chernyshevsky, Saratov State Medical University
Summary:

Objective: to optimize the process of biomechanical modeling of blood vessels on the example of creating models of the arterial circle of the brain. Material and Methods. Biomechanical modeling requires the creation of a patient-oriented three-dimensional solid-state geometric model of the object under study. This problem can be solved by computer data processing (CT) or magnetic resonance (MRI) tomography. A program that implements the construction of blood vessel contours on individual sections of MRI in semi-automatic mode. These contours are exported as saved curves in a specifc format to SolidWorks, where they are used to create three-dimensional models of blood vessels. The models obtained in this way take into account the personal characteristics of the structure of the vascular bed of a particular patient and can be used in the process of biomechanical modeling. Results. The results of the program implementation of the recursive frontal growth method for processing two- dimensional slices of tomograms are presented. Conclusion. The developed software allows semi- automatic loading of DICOM images and obtaining fat sections of vessels on their basis, as well as transferring them for further processing into computer-aided design systems.

Heading: Sociology of Medicine Article type: Original article
Authors: Balashova М.Е., Shemetova G.N., Gubanova G.V.
Organization: Saratov State Medical University
Summary:

Aim: assessment of risk factors for chronic non-communicable diseases in medical students to improve measures for the formation of a healthy lifestyle. Material and Methods. In order to identify risk factors for chronic non-communicable diseases, a questionnaire method was used. A survey included 80 frst- year students and 80 sixth-year students of medical school. The questionnaire included information about the sex, age, smoking and alcohol consumption, physical activity, and nutrition. Results. Respondents are characterized by a high frequency of risk factors for chronic non-communicable diseases (СNCD): low physical activity (60.0 %), poor diet (81.0 %), smoking (16.2 %). The combination of risk factors for the development of СNCD was revealed in 31.8 % of students. Conclusion. The high frequency of risk factors for CNS among students indicates the need to improve measures to increase the efectiveness of prevention, therapeutic measures and the formation of a healthy lifestyle.

The existing methods of treatment of this pathology are efective, but the question of reducing the surgical stress of patients who underwent surgery, reducing the number of complications, early mobilization and early recovery remains relevant. The presented literary review reveals the provisions proposed in the XX century, multimodal strategy «Fast track sur-gery», revealing the tactics of surgical patients throughout the perioperative period. The application of this protocol shows its efectiveness in reducing the duration of hospitalization and early rehabilitation of the considered group of patients.

Summary:

Purpose: to analyze the expression of immunohistochemical markers in patients with prostate adenocarcinoma at high risk of progression before and after combined and combined treatment of patients with prostate specific antigen (PSA) level of blood below discriminatory. Material and methods. Examined patients (n = 80) with a diagnosis of “High-risk progression prostate cancer,” with clinical stage T3a, total score for Gleason scale from 8 to 10, the level of total PSA more than 20 ng / ml. Patients of the 1st group (n = 42) only combined surgical treatment in the scope of TUR and HIFU ablation the prostate; The 2nd group of patients (n = 38) additionally applied androgen deprivation in adjuvant mode. Results. Blood PSA, determined in patients after various methods of treatment is not always an objective indicator of its effectiveness. Immunohistochemical studies of tumor tissue for proliferative activity tumor cells, the activation of apoptosis in them, as well as the assessment of specific tumor markers and tumor suppressor genes showed that a decrease in the expression of these markers in patients with PSA values ​​of blood lower than discriminatory observed in all patients independently on the type of treatment. However, after treatment in the 1st group of patients, despite the achievement PSA level of nadir, there is a decrease in the expression of an intercellular adhesion marker E-cadherin, which indicates an increased risk of tumor metastasis, as well as increased expression of markers of the apoptosis inhibitor Bcl-2 and androgens, which indicates about the possibility of progression of tumor growth. Conclusion For a more accurate assessment therapeutic pathomorphism in patients with prostate cancer at high risk of progression, which HIFU ablation monotherapy was carried out, along with the determination of blood PSA level, it is necessary during the control biopsy of the prostate immunohistochemical studies of tumor tissue to determine the prognosis and risk of relapse.
