Six-year results of the regional medical center department of cardiac surgery
Abstract
Aim. To summarize the experience of the first years of activity in the department of cardiac surgery of the regional medical center.
Methods. 5549 patients with cardiovascular diseases were treated from December 2008 to December 2014, including 3041 patients who underwent surgeries, among them - 1585 vascular interventions, 1128 hearts surgeries. The study included patients operated on the heart and aortic arch, 238 of them had surgeries in 2014 [854 male (75.7%), 274 female (24.3%), aged 22 to 81 years (57.8±8.9)].
Results. Number of performed surgeries was assessed to find out whether it matches with the population needs. For coronary heart disease, 880 patients underwent surgeries, 10 were operated for coronary heart disease complications, 132 - for heart valve disease, 16 - for congenital heart disease, 56 - for combined heart disease, 18 - for aortic aneurysms, 16 - for cardiac tumors, 3 for pulmonary embolism and aortic dissection (type 1). The number of heart surgery using cardiopulmonary bypass in recalculation per 1 million inhabitants in 2014 was 317. Thanks to the active work of the regional medical-diagnostic center, significant progress was made in timely identification and providing specialized care to patients with cardiovascular diseases to meet the population needs in high-tech medical care in the region.
Conclusion. Evaluation of the study results reveals that the introduction of cardiac surgeries for cardiovascular diseases in the regional center promotes approximation of high-tech medical care to the population of remote regions, improves the quality of treatment in patients with cardiovascular conditions.
Searching for methods to predict septic complications in surgical patients
Abstract
Aim. To assess the significance of acute stage reactants as the marker for purulent complications in surgical patients.
Methods. We analyzed the results of treatment of 228 patients with purulent and inflammatory diseases of soft tissues, treated in 2011-2014. Acute phase reactants: C-reactive protein, albumin and fibrinogen were measured starting from the day of admission and surgical treatment and during the next 7 days. The control group (112 patients) included patients whowere treated conventionally by gauze bandage with water-soluble ointments and antiseptic solutions and broad-spectrum antibiotics. In the study group (116 patients) topical treatment of wounds was performed using «Poliderm» bandages.
Results. Application of the «Poliderm» combined dressing reduced the wounds clearance term from 4.3±0.5 to 3.2±0.4 days, active inflammation term from 8.8±1.3 to 6.4±0.7 days, epithelialization of the wound from 10.1±0.8 to 8.4±0.6 days. C-reactive protein level was 87.3±4.3 g/l at the day of admission and decreased by day 7 to 34.13±1.2 g/l, compared to 51.83±3.6 g/l on the 7th day in the control group. Albumin level was 42.73±3.7 g/l in the study group with further decrease to 40.33±1.7 g/l on the 2nd and subsequent increase up to 45.13±1.3 g/l on the day 7. Patients of the control group had albumin level decreased on the 2nd and 3rd days with further increase up to 41.73±2.1 g/l on the day 7. At the treatment start, leukocyte intoxication index was 5.923±0.4 in the main group and 5.873±0.3 in the control group. On the 2nd day, this parameter decreased to 5.12 in the main group and to 5.41 in the control group.
Conclusion. Measuring the levels of acute phase reactants (C-reactive protein, albumin, etc.) allows to assess the clinical course of a purulent and inflammatory disease, to register the good treatment effect on the 1-2nd day of treatment, even before the significant clinical changes, changes in the body temperature, white blood cell counts, erythrocyte sedimentation rate.
Creating an arteriovenous fistula in patients with chronic kidney disease stage 5
Abstract
Aim. Comparative assessment of microsurgical and traditional methods for creating an arteriovenous fistula for long-term hemodialysis in patients with chronic renal failure.
Methods. Results of arteriovenous fistula surgeries for creating arteriovenous fistula for long-term hemodialysis in 169 patients with chronic renal failure in the period from 2008 to 2013 were analyzed. The main group included 87 patients in whom arteriovenous fistula was formed by microsurgery. For fistula thrombosis prophylaxis, 40 mg of nadroparin calcium (fraxiparine) was used in this group after surgery as a postoperative bolus, followed by 7 days subcutaneous administration. Arteriovenous fistula in patients of the main group underwent anti-thrombogenic treatment: paravasal tissues and vessel outside were irrigated by 1% sodium chloride methylthioninium (methylene blue) after the main phase of the operation, followed by lysine acetylsalicylate standard solution after 2 minutes. The control group included 82 patients in whom fistula was created conventionally without using microsurgical techniques. For arteriovenous fistula thrombosis prevention, 5000 IU of sodium heparin was used 4 times a day in patients of the control group.
Results. In the main group, five cases of fistula thrombosis were observed in patients with diabetes mellitus and two in patients with chronic glomerulonephritis. In the control group, arteriovenous fistula thrombosis in the early postoperative period was recorded in 13 patients with diabetes mellitus, in four - with chronic glomerulonephritis, and in one - with polycystic kidney disease. In one (1.15%) patient of the main group and in three (3.66%) in the control group, wound infection associated with inflammatory processes development at the surgical wound was noted.
Conclusion. Microsurgical formation of arteriovenous fistula in patients with terminal stage of chronic kidney disease is the method of choice (especially with concomitant diabetes mellitus), allowing to significantly reduce the risk for arteriovenous fistula thrombosis and therefore reduce the number of unsatisfactory results.
Studying the processes of free-radical oxidation in patients with purulent-inflammatory diseases of soft tissues
Abstract
Aim. To study the effects of combined dressings on the processes of free radical oxidation in patients with purulent wounds.
Methods. The performance of luminol-dependent chemiluminescence of whole blood from 30 healthy donors and 122 patients with purulent wounds, as well as tissue chemiluminescence of festering wounds tissue homogenates were examined before and after the treatment. To assess the free radical oxidation in vitro, spontaneous and zymosan-induced whole blood chemiluminescence measurement, iron-induced chemiluminescence assessment of festering wounds tissue homogenates were performed. The distribution of chemiluminescence parameters compared to normal expected distribution was analyzed to group homogeneity on these criteria.
Results. Group of donors was homogeneous in composition that allowed the calculation of mean values. By changing in whole blood chemiluminescence of patients with soft tissue festering wounds, they were allocated to two groups, in which a marked increase or decline of the investigated parameters was seen. Increased luminol-dependent blood chemiluminescence indicates excessive free radicals generation by phagocytes and is characteristic of acute inflammation. Decreased intensity of chemiluminescence was observed in the blood of patients who showed reduced functional activity of phagocytes, which, together with the clinical features indicate a long-term smoldering inflammation. The comparative assessment of «Poliderm», «Voskopran», «Polysorb», «Levomekol» medications, used for local treatment of suppurative wounds, influence on free radical oxidation in model systems in vitro, was performed.
Conclusion. There is a triple increase in chemiluminescence intensity in the acute phase of the inflammatory process, marking increased production of reactive oxygen radicals with microbicide activity); in long-term smoldering processes, chemiluminescence decreases by half, indicating reduced efficiency of protective mechanisms
Comparative analysis of conventional and video-assisted surgeries on thyroid and parathyroid glands
Abstract
Aim. A comparative analysis of conventional and video-assisted operations effectiveness.
Methods. The study included 80 patients were operated from 2010 to 2015 for thyroid and parathyroid glands diseases. The first (main) group included 35 patients who underwent video-assisted surgery. The second group (comparison group) included 45 patients who were operated conventionally. Surgery for thyroid gland diseases included hemithyroidectomy, for diseases of the parathyroid glands - parathyroidectomy in patients with tertiary hyperparathyroidism and adenoma resection in patients with primary hyperparathyroidism.
Results. In video-assisted hemithyroidectomy, mean surgery duration was 42.2±3.6 min, compared to 34.4±2.8 min (p=0.086) in conventional method. Recurrent laryngeal nerve and parathyroid glands were identified in 73% of cases at conventional surgery, compared to 96% at video-assisted hemithyroidectomy (p=0.012). At video-assisted surgeries, no phonation disorders were recorded, while at conventional surgeries they were diagnosed in 7 patients (14.0%, p=0.041). Transient hypocalcemia according to the results of laboratory tests was observed in 1 (3.3%) patients after video-assisted and in 3 (6.0%) patients after conventional surgery (p=0.998). The average length of hospital stay after conventional surgery was 8.1±1.8 days, and after video-assisted surgery - 2.6±1.6 days (p=0.040). Postoperative scar size in the group of video-assisted surgery not exceeded 3 cm, in the group of conventional surgery - up to 7 cm.
Conclusion. With proper selection of patients, particularly with parathyroid gland diseases, are video-assisted surgery might be a method of choice. Using video-assisted surgery in treating patients with thyroid gland diseases allows to identify anatomical structures of the neck in detail.
Potential humoral markers of gastric and duodenal stress ulcers accompanied by concomitant head injury
Abstract
Aim. To evaluate the significance of a number of humoral indicators in gastrointestinal bleeding at various stages of severe concomitant head injury.
Methods. The study included 347 patients with severe head injuries (brain contusion, intracerebral hemorrhage) associated with fractures of the extremities and pelvis (215 patients), abdominal organs injuries (75 patients), chest and lung injuries (57 patients). Samples of blood and stomach contents were taken on the 1st, 3rd, 5th, 8th, 9th, 12th, 15th and 18th days after the injury. Esophagogastroduodenoscopy was performed on the 3rd, 5th, 7th and 10th day after the trauma. Anti-streptolysin O, antihyaluronidase, C-reactive protein, sialic acids levels were determined by serum titration and precipitate formation.
Results. On the 1st day, anti-streptolysin O level exceeded normal values (by 4.1±1.3 IU/ml), reaching a maximum value by 8-10th day (exceeding the normal range by 61.3±1.7 IU/ml) with further decrease after the 15th day. Antihyaluronidase level was permanently increased from the 5th day of observation. C-reactive protein level was higher than normal from the first day of study (0.1±0.17 mg/l), with further upward trend, reaching its peak on day 9, indicating continuous inflammation. Sialic acids level in the first days was twice as high as the normal level, and remained almost at the same level until the end of the study. Endoscopic examinations in 21 patients with gastrointestinal bleeding showed that in 11 (52.4%) cases, the source of bleeding were acute gastric and duodenal erosions and ulcers, in 5 (23.8%) cases - chronic gastric and duodenal ulcers, in 5 (23.8%) cases bleeding occurred due to exacerbation of chronic duodenal ulcer.
Conclusion. Changes in serum anti-streptolysin O, antihyaluronidase, sialic acids levels in patients with severe head injuries, combined with other injuries may reflect the pathogenesis of acute gastroduodenal erosions and ulcers and be considered as the markers for their development.
On the possibility of an increased risk of breast cancer in patients who underwent breast surgeries for benign diseases
Abstract
Aim. Assessment of risk of breast cancer secondary to earlier breast surgery for benign disease.
Methods. The initial sample group of breast cancer included 295 patients who were followed up for 2006-2010. The final sample group of breast cancer (for primary analysis) was formed from this group and included 204 patients in order to provide accurate comparison with the control group on factors affecting the breast surgery probability for benign processes for life and on the lifetime risk for breast cancer. The control group included 1141 patients. The rate of surgical interventions for benign breast diseases was compared in the breast cancer group for primary analysis and the control group.
Results. The rate of surgical interventions was significantly higher in breast cancer patients: (7.35 vs. 3.94% in the control group): odds ratio for breast cancer patients was 1.137; 95% confidence interval 0.981-1.318 (p=0.03). Duration of the gap between the initial surgical and subsequent development of breast cancer on operated side was 20.05±11.373 years (variation range - 8 to 54 years).
Conclusion. Performed breast surgery might increase the risk of future developing breast cancer; however, a long-term study is needed to confirm these data.
Contour analysis of mammographic images in benign and malignant breast diseases
Abstract
Aim. Development and evaluation of the diagnostic value of techniques for quantitative analysis of masses on mammographic images satisfying the requirements of categories 2-4 in BIRADS (Breast Imaging Reporting And Data System - the system for classification and description of breast imaging results of the American College of Radiology).
Methods. Images of 375 focal lesions revealed on mammography (211 malignant and 164 benign, all were verified morphologically), satisfying the criteria 2-4 according to BIRADS classification, were analyzed. Mathematical processing was performed using the MammCheck 1.15 software package developed by authors, which uploads the obtained images. Contour, segments of area, peripheral outlines, homogeneity and inner outlines indexes were calculated.
Results.The statistical analysis of foci at standard mammography images of BIRADS 2-4 categories revealed no statistically significant difference in all four estimated parameters. When using tomosynthesis images, statistically significant difference was discovered in the outline index in the groups of benign and malignant foci (mean ± standard deviation: 1.73±1.11 vs. 3.11±2.02, respectively, p
Conclusion. Outline analysis of mammograms, including those obtained using tomosynthesis, does not provide the necessary level of specificity for the differential diagnosis of benign and malignant microcalcifications and clusters.
Primary percutaneous coronary interventions in patients with ST-segment elevation myocardial infarction complicated by «no-reflow» phenomenon
Abstract
Aim. To study the association of «no-reflow» phenomenon incidence and the method of primary percutaneous coronary intervention for ST-segment elevation acute myocardial infarction, and to determine the optimal tactics for primary coronary intervention.
Methods. A retrospective analysis of 1339 cases of primary percutaneous coronary intervention for ST-segment elevation myocardial infarction performed in the period from January 2008 to June 2013 was executed. Depending on surgery method, all the patients were allocated to four groups: first group - direct stenting (n=483); second group - thromboaspiration before stenting (n=142); third group - balloon angioplasty and stenting using a small-diameter balloon ≤2.0 mm (n=491); fourth group - balloon angioplasty and stenting using a small-diameter balloon and subsequent use of medium and large-diameter balloons ≥2.0 mm (n=223).
Results. «No-reflow» phenomenon was observed in 164 (12.2%) of cases, incliding 34 (7.0%) cases in the first group, 12 (8.4%) cases in the second group, 53 (10.8%) cases in the third group, and with the majority of cases seen in the fourth group - 65 (29.1%). At primary percutaneous coronary intervention, the following incidence of «no-reflow» phenomenon was observed depending on the infarct-related artery: left anterior descending artery - 85 cases (51.82% of the total number), right coronary artery - 51 (31.09%) cases, circumflex artery - 28 (17.07%) cases, and diagonal branch - 1 (0.6%) case.
Conclusion. In primary percutaneous coronary intervention with direct stenting and thromboaspiration before stenting, the incidence of «no-reflow» phenomenon is significantly lower. Patients who undergo primary percutaneous coronary intervention preceded by repeated balloon angioplasty using medium and large-diameter balloons are at higher risk for «no-reflow» phenomenon.
Regional experience of acute coronary syndrome surgical treatment
Abstract
Aim. To summarize the experience of surgical myocardial revascularization in acute coronary syndrome.
Methods. The study included 72 patients with acute coronary syndrome who underwent coronary artery bypass grafting in the department of cardiac surgery. All patients were allocated to 3 groups depending on the urgency and the risk of intervention: first group - emergency coronary artery bypass grafting; second group - urgent coronary artery bypass grafting in patients at high risk of adverse events; third group - delayed coronary artery bypass grafting in patients at low risk of adverse events.
Results. On-pump coronary artery bypass grafting was performed in 2 (25%) patients, off-pump coronary artery bypass grafting - in 6 (75%) patients, including 3 patients who were operated using parallel off-pump coronary artery bypass grafting technique. Positive clinical results were achieved in all patients. Patients with high risk for adverse events (n=55) underwent surgery in a period of 1 to 10 days from onset of disease (average delay was 4.3±2.6 days). Surgeries using extracorporeal circulation were performed in 39 (71%), including off-pump coronary artery bypass grafting - in 16 (29%), of whom 9 patients underwent parallel off-pump coronary artery bypass grafting. Intra-aortic balloon pump was used in 4 patients. Unfavorable outcome in this group was registered in 10 (13.8%) cases. Patients with a low risk of adverse events (n=9) underwent coronary artery bypass grafting after 10 days from the onset of the disease. All patients were operated using extracorporeal circulation. Unfavorable outcomes were not registered in that group.
Conclusions. A decision to perform coronary artery bypass grafting in patients with acute coronary syndrome with ST elevation is made when it is impossible to perform coronary angioplasty due to the isolated and combined stenosis of left main coronary artery and other arteries of the heart. Coronary artery bypass grafting in patients with acute coronary syndrome associated with a high risk for adverse events should be performed as an emergency intervention using intra-aortic balloon pump. Off-pump coronary artery bypass grafting is associated with a lower risk of adverse events, require little or no blood transfusion, and reduce hospital stay.

Long-term results of eversion surgeries for internal carotid artery stenosis due to atherosclerosis
Abstract
Aim. Analysis of long-term results of eversion carotid endarterectomy in patients with atherosclerotic carotid stenosis.
Methods. 272 eversion carotid endarterectomy surgeries was performed from June 2008 to December 2014 in the department of cardiac surgery. Long-term results were studied in 198 (73%) patients, with follow-up term ranging from 6 to 48 months. The method of operation serves as a criterion separating Patients were allocated into two groups by the surgery method: in the first group, eversion endarterectomy was performed by Kieny, in the second - by DeBakey.
Results. Reconstructed ipsilateral internal carotid artery was passable during the follow-up period in 100% of cases, as confirmed by ultrasonography. In the late period, the mortality in the first group was 2.3% (myocardial infarction and cancer), compared to 1.5% in the second group (myocardial infarction). Acute ischemic stroke occurred in 0.8% of the first group patients and in 1.5% of the second group patients. Restenosis of 50 to 69% were discovered in 3.7% of cases in first group and in 3% in the second group. Restenosis ≥70% were found in 1.5% in both groups of patients.
Conclusion. The obtained data confirm that both methods of eversion carotid endarterectomy are safe and reliable in treatment of carotid arteries atherosclerosis and, thus, preventing stroke.

Methods. 80 patients (40 males, 40 females) with congestive heart failure of stages I, IIA and IIB aged 36 to 78 years were examined.
Results.Score model for myocardium ischemic preconditioning assessment in patients with congestive heart failure was introduced. The phenomenon of ischemic preconditioning was most often in patients with chronic heart failure stage I compared to stages IIA and IIB (p
Conclusion. The effect of ischemic preconditioning might be used as one of the factors for myocardial protection at congestive heart failure.
Changes in gepatopancreatobiliary system organs and quality of life in patients after cholecystectomy
Abstract
Aim. To assess the condition of hepatopancreatobiliary system and quality of life in patients in the remote period after cholecystectomy.
Methods. 88 patients with cholelithiasis who undergone cholecystectomy in 2008-2010 were examined 5 years after the surgery. Common blood count, blood biochemistry test were performed, fasting blood glucose level was measured, esophagogastroduodenoscopy, ultrasonic examination of abdominal organs, fractional duodenal intubation, fecal elastase test (ELISA, «BioServ Diagnostics», Germany) were performed. Patients filled out questionnaires to assess the quality of life: MOS SF-36 (Medical Outcomes Study Short Form), GIQLI (Gastrointestinal Quality of Life Index) before, 1 and 5 years after cholecystectomy.
Results. According to the esophagogastroduodenoscopy, 56 (63.6%) patients had duodenal reflux, 21 (23.8%) - duodenal diverticula, 9 (10.2%) - reflux esophagitis. Reduced fecal pancreatic elastase-1 was detected in 37 (42%) of patients. According to the fractional duodenal intubation, hypersecretory type was the most prevalent, 40 (45.5%) patients had hypotonic sphincter of Oddi, 48 (54.5%) - hypertonic sphincter of Oddi. All patients had crystals of calcium bilirubinate, leukocytes and bacteria in bile, microliths were identified in 76 (86%) of patients. After emergency surgery, quality of life increased by all indicators, after planned cholecystectomy for asymptomatic cholelithiasis the quality of life decreased 1 and 5 years after cholecystectomy. After planned cholecystectomy for symptomatic cholelithiasis, the surgery improved quality of life, but after 5 years indicators for quality of life returned to preoperative levels.
Conclusion. Various changes in hepatopancreatobiliary system organs are detected in patients after cholecystectomy, like disorders of bile formation and biliary excretion, sphincter of Oddi dysfunction, decreased function of the pancreas, which reduce the quality of life.
Bile acids serum levels in patients with nonalcoholic fatty liver disease
Abstract
Aim. To estimate the blood levels of primary, secondary, tertiary and unconjugated bile acids in patients with non-alcoholic fatty liver disease.
Methods. The study included 74 patients with non-alcoholic fatty liver disease (males - 30, females - 44) and 51 healthy individuals (males - 14, females - 37). All patients underwent anthropometry and complete clinical, biochemical and instrumental examination (measuring the subcutaneous fat layer). 64 patients had hepatic steatosis, 10 - steatohepatitis. Serum levels of bile acids (primary: cholic, chenodeoxycholic; secondary: lithocholic, deoxycholic and tertiary: ursodeoxycholic) were measured by gas-liquid chromatography on «Chromos GC-1000» (Russia) scanner.
Results. Unconjugated primary, secondary and tertiary bile acids were detected in the blood of healthy individuals and patients with non-alcoholic fatty liver disease. In healthy individuals, there were no gender differences found in the bile acids levels. Patients with non-alcoholic fatty liver disease had higher level of bile acids compared to healthy controls. There was a significant difference in the concentrations of secondary and tertiary bile acids in patients with hepatic steatosis and steatohepatitis.
Conclusion. Blood bile acids levels were significantly higher in patients with non-alcoholic fatty liver disease than in healthy individuals. At steatohepatitis, females had higher levels of cholic, chenodeoxycholic and deoxycholic acids and lower levels of lithocholic and ursodeoxycholic acids compared to males. Significant difference in patients with hepatic steatosis and steatohepatitis was revealed only in levels of secondary and tertiary bile acids.
Evaluation of the level of glycoproteins in the vitreous body in degenerative diseases of the retina
Abstract
Aim. A comparative assessment of fibronectin and laminin levels in the vitreous body in patients with idiopathic macular hole, epimacular fibrosis and age-related macular degeneration.
Methods. Glycoprotein levels were measured in the vitreous body of 63 patients aged 56 to 81 years (65±2.8 years). The first group included 24 patients with idiopathic macular hole, second group - 14 patients with epimacular fibrosis, third group - 15 patients with the wet form of age-related macular degeneration. The control group included 10 patients with contusion dislocation of the lens into the vitreous body without signs of retinal pathology.
Results. Laminin level in the vitreous body in patients of the control group was 0.71±0.03 mg/ml, fibronectin level - 34±5.5 mg/ml, no association of these parameters with patients’ age and sex was revealed. Laminin and fibronectin levels in vitreous body of patients with idiopathic macular hole were 0.8±0.23 and 32.8±2.1 mg/ml, respectively, in patients with epimacular fibrosis - 0.8±0.23 and 32.0±0.53 mg/ml, respectively, and in patients with wet form of age-related macular degeneration - 0.9±0.25 and 33.0±1.65 mg/ml, respectively. Strong direct association between laminin level in the vitreous body and retinal thickness was revealed in patients with idiopathic macular hole and epimacular fibrosis.
Conclusion. The link between the retinal thickness and laminin level might indicate the involvement of laminin in degenerative changes of the retina on the level of vitreoretinal interface and inner retinal layers.
Differential diagnosis of hemangiomas and other orbital masses
Abstract
Aim. To determine the differential diagnostic scintigraphic signs of hemangiomas and malignant tumors of the orbit.
Methods. Comprehensive survey of 35 patients with orbital masses included a standard eye examination, ultrasound Doppler sonography, computed tomography or magnetic resonance imaging, scintigraphy using in vivo labeled 99mTs erythrocytes, and morphological study.
Results. Scintigraphic studies using in vivo labeled 99mTs erythrocytes in 18 patients with hemangioma of the orbit, no accumulation of radiotracer in the dynamic phase of the study was observed. On the subsequent delayed planar scintigraphy and single-photon emission computerized tomography, intense delayed hyperfixation of in vivo labeled 99mTs erythrocytes in the lesion was revealed. In 8 patients with malignant orbital tumors (adenocarcinoma of the lacrimal gland - 4, osteogenic sarcoma - 1, olfactory neuroblastoma - 1, metastasis of renal cancer in orbit - 1) there was an intense accumulation of labeled erythrocytes in the projection of the affected area in all phases of the nuclear study. In patients with adenoma of the lacrimal gland, cranioorbital meningioma, orbital pseudo tumor, as well as in 1 patient with lacrimal gland adenocarcinoma, no pathological accumulation of in vivo labeled 99mTs erythrocytes in the lesion was observed at any stage of the study.
Conclusion. According to the results of scintigraphic studies: (1) patients with orbital hemangioma had no accumulation of in vivo 99mTs labeled red blood cells in the vascular (dynamic) phase of the study and had hyperfixation of radiotracer in delayed planar scintigraphy and single-photon emission computerized tomography; (2) intensive accumulation of labeled 99mTs erythrocytes in tumor vascular (dynamic) phase of the study as well as in delayed planar scintigraphy and single-photon emission computerized tomography was characteristic of malignant neoplasms with hypervascularization.

Evaluation of the presence and localization of P2 receptors in human blood vessels
Abstract
Aim. To study the presence and localization of the P2X and P2Y receptor subtypes in the human cystic artery and great saphenous vein (with and without varicose disease).
Methods. Segments of the human blood vessels were stained using a standard two-step immunohistochemical analysis using primary and secondary antibodies. In the experiments primary antibodies to the following receptors were used: Р2Х1, Р2Х2, Р2Х3, Р2Х4, Р2Y1, Р2Y2, Р2Y4. In order to determine the presence of a receptor in a vessel sample a comparison was made between staining of the experimental and the control samples, which were not treated with primary antibodies.
Results. Immunohistochemical analysis of the cystic artery showed the presence of Р2Х1, Р2Х3, Р2Y1, Р2Y2 receptors. All receptor subtypes were found to be located in the muscular layer of the artery, whereas the P2Y1 receptor was also expressed on the surface of the endothelial cells. In the great saphenous vein without varicose disease Р2Х1, Р2Х2 и Р2Y1 receptor subtypes were identified, all of which were found to be located on the smooth muscle cells of the vein. Similarly to the cystic artery, the Р2Y1 receptor was also found within the endothelial layer of the vein. At the same time, only Р2Х2 и Р2Y1 receptor subtypes were expressed in the muscular layer of the great saphenous vein affected by varicose disease. No P2 receptor subtypes were identified on the endothelial layer of the varicose-diseased vein.
Conclusion. Different P2 receptor subtypes were found to be present in the smooth muscle and endothelial layers of the human cystic artery and great saphenous vein. The identified differences in the receptor subtypes between samples of great saphenous veins with and without varicose disease are, most likely, explained by the restructuring of the receptor apparatus as a result of varicose disease progression.

Managing platelets bank in the regional blood supply service
Abstract
Aim. To develop the system of regional management of platelets bank based on the analysis of platelet concentrate supplies to Irkutsk region healthcare facilities.
Methods. Irkutsk Regional Blood Transfusion Center expedition service reporting forms, branch statistical reports, accounting records of blood supply service facilities of Irkutsk Region for 2014 were analyzed.
Results. To ensure the proper supply of Irkutsk region healthcare facilities with platelet concentrate, the main activities for stock management were determined: (1) key customers interaction management - by exploring the need for platelets and developing a mechanism for request planning for the next 7-9 days; (2) advance request execution - by donor acquisition, platelet concentrate production management, interaction with other institutions of the blood supply service; (3) platelet donation campaign. Regional management system for platelet stock was developed.
Conclusion. Regional management system for platelet stock consists of 7 elements: (1) constant interaction with key customers: daily monitoring of healthcare facilities’ needs for platelet concentrate and planned advance requests for platelet concentrates; (2) anticipatory appointments for donors for platelet apheresis; (3) formation of platelet donors registry; (4) providing pediatric dosages of platelet concentrates for pediatric healthcare facilities; (5) combination of different ways of platelet concentrates preparation (production of platelet concentrates recovered from regular blood donors blood allows to create a «safety net» for emergencies); (6) arranging the planned production of platelet concentrates for Irkutsk at the branches of Irkutsk Regional Blood Transfusion Center, as well as in other Irkutsk Region regional blood supply service facilities; (7) promotion of platelet donation in blood supply service facilities.

Abstract
Major histocompatibility complex genetic variants in potential hematopoietic stem cells donors in Republic of Kazakhstan
Abstract
Aim. To compare the prevalence of HLA-system antigens genetic variants in potential hematopoietic stem cells donors in Kazakhstan and worldwide.
Methods. Prevalence of HLA-antigens genetic variants in blood samples of potential hematopoietic stem cells donors included in hematopoietic stem cells donors register of Kazakhstan was analyzed and compared to a «Allele frequencies in Worldwide populations» database developed by the Royal Liverpool University Hospital.
Results. The biggest overlap of Kazakhstan and World registers was seen in the distribution of 31-01 allele: 68 (4.5%) in Kazakhstan register, 1678 (4.63%) worldwide; odds ratio (OR) = 0.97 (0.76 to 1.24), F=0.851441, χ2=0.06. The biggest difference between the two registers was found in the distribution of locus A antigens: A 02-01 (χ2=24.59), A 02-07 (χ2=24.42), A 32-01 (χ2=27.1), A 02-37 (χ2=23.96), A 11-38 (χ2=3.96). In locus B alleles, the biggest overlap between the two comparison groups was in В 14:02 allele: Kazakhstan register - 31 (2.05%), worldwide register - 757 (2.01%) [OR=1.02 (0.71 to 1.47), F=0.851990, χ2=0.01], followed by 38:02 (χ2=0.02), 44:05 (χ2=0.03), in 27:07 (χ2=0.04), 54:01 (χ2=0.07). The biggest difference between the two registers was in 13:02 (χ2=256.9), 08:01 (χ2=26.92) locus B alleles. Distribution of locus C alleles was discovered to have the biggest statistical similarity of two registers provided by C 07:01 (χ2=0.07), 08:02 (χ2=0.15), 15:02 (χ2=0.23) 12:03 (χ2=0.76). The biggest difference in the distribution of locus C alleles between the two registers was in 06:02 (χ2=125.78) and C 03:02 (χ2=103.64).
Conclusion. The overlap of HLA-antigens genetic variants distribution in Kazakhstan and global registers varies from 41 to 52% by loci (locus A - 50%, B - 52%, C - 48%, DRB1 - 51%, DQB1 - 41%, mean 48.4%, median 50%). Kazakhstan register contains information on unique HLA-antigens genetic variants not included in the general database, manifesting the need for national register development and its integration into the «Allele frequencies in Worldwide populations» register.

Hematological and biochemical screening of blood donors in the Republic of Bashkortostan
Abstract
Aim. To assess the hematological and biochemical screening effectiveness in blood donors in the Republic of Bashkortostan.
Methods. The results of hematological and biochemical screening in blood donors in the Republic of Bashkortostan in 2008-2013 were studied.
Results. Centralizing and modernizing of blood donors examinations at the Republican Blood Transfusion Centre of the Bashkortostan Republic in 2008-2013 has led to an increase in the number of clinical blood analyses by 53.1%, reaching from 74.1 to 666.9% for some parameters. Studying platelet counts allows to choose platelets donors, whose blood is optimally used for preparing platelet-rich transfusion media. Leukocytosis (5.01%, 1748 of 34 899 subjects), leukopenia (0.1%; 34 of 34 899 subjects) and alterations in erythrocyte sedimentation rate (4.83%, 1574 of 32 581 subjects) may indicate a bacterial infection. In the presence of these signs, it might be appropriate do disallow donating platelets to prevent bacterial contamination of platelet concentrates and complications in the recipient, all the more so as the current mandatory control of blood products sterility is far from being perfect. Deviations in reticulocytes levels during the 6 years of follow up was discovered in 26 (0.05%) of 52 379 donors and in all cases was associated with a low concentration of hemoglobin. Obviously, the screening of this indicator is needless. The substantial part of potential donors infected with hepatitis B virus (80.6%) and C (65.2%) showed no evidence of cytolysis, which once again raises the question of the diagnostic value of alanine aminotransferase level screening in blood donors testing.
Conclusion. The excessiveness for combined screening for hemoglobin and hematocrit levels, reticulocyte concentrations, bilirubin levels was demonstrated. Efforts targeted at the forming of stable population of donors reduced the donation exemptions due to low hemoglobin level and presence of specific markers for viral hepatitis.
Distribution of blood groups among the donors of the Republic of Tatarstan
Abstract
Aim. To study the peculiarities of AB0, Rh and Kell blood group distribution in donors of the Republic of Tatarstan in detail.
Methods. Blood samples of 180 279 donors of blood components (erythrocytes, platelets, serum) donated form 2008 to 2014 both in hospital and mobile settings were analyzed. The material for the study was the blood donors of blood components (red blood cells, plasma and platelets) for the period 2008-2014, the city, donated blood, both in stationary and in exit conditions. Typing erythrocyte antigens for AB0, Rh and Kell systems was performed using «Scangel» gel technology by «Hemos SP II» and IH-1000 immunohematologic analyzers using the diagnostic card produced by «Bio-Rad laboratories», as well as by microtray method on «Galileo Neo» automated scanner, and on plate by anti-A, anti-B, anti-AB, anti-A1, anti-C, anti-Cw, anti-c, anti-D, anti-E anti-e and anti-Kell monoclonal reagents produced by «LLC Gematolog» (Moscow), LLC «Mediklon» (St. Petersburg), «ImuMed» (Germany). AB0 blood group was also determined by the cross method using own-produced AB0 standard isohemagglutinating sera and AB0 standard red blood cells. Rhesus blood group was also determined by own-produced universal a-D, a-DC reagent, used to identify Du gel cards produced by «Bio-Rad laboratories», «Grifols» were used for Du detection. Statistical analysis was performed and the data were obtained using the automated information system for Transfusions management, installed in the Republican Blood Centre in 2008.
Results. Analysis of AB0 system blood groups distribution in the Republic of Tatarstan showed that blood group 0 (I) was the most common - 33.7%, 31.1% donors had A (II) blood group, 23.7% donors - B (III) group, 11.5% - AB0 (IV) group. Anti-A1 irregular agglutinin was found in 5 (0.57%) out of 878 donors with A2 (II) group, and in 53 (12.4%) of 428 A2B (IV) donors. The shares of Rh (D)-positive and Rh (D)-negative donors (87.4 and 12.6%, respectively), was revealed. Rh-positive donors included donors having antigen phenotypes C, E, and Du.
Conclusion. Formation and completion of a serologically tested donor’s database in the Republic of Tatarstan is required to compile the gene geographic map of the region.
Evolution of the motivation for donating blood and blood components in the regions of the Republic of Kazakhstan
Abstract
Aim. To evaluate features of the evolution of blood donation in Kazakhstan, including motivation and types of donations.
Methods. Statistical data of blood donations in the Republic of Kazakhstan for 2010-2014 were studied.
Results. In 2014, 51.8% of all blood donations in Kazakhstan were done by voluntary donors, 35.5% - by recipient’s relatives. The median proportion of paid donations in 2012-2014 years dropped by twice: 15.3; 10.5 and 7.6%, respectively. The number of platelet donations in 2010-2014 years increased by 717.3, of which 77% came from the cities of Astana and Almaty, where high-tech medical care is mainly provided. The number of plasma donations in 2014 compared to 2010 year has decreased by 35.7%, while its share in total number of donations dropped by 40.2%. Preparations are underway to contract plasma fractionation, becomes an actual the problem of determining blood donor reserves for plasma donations.
Conclusion. Voluntary blood donations (51.8%) prevail in Republic of Kazakhstan; the the number of platelet donations increased by 717.3% in 2010-2014, the number of plasma donations dropped by 40.2%, which reveals the potential for implementing contract fractionation.

Features of infusions and tranfusions within the complex treatment in patients with multisystem trauma
Abstract
Aim. To analyze features of infusions and transfusions within the complex treatment in patients with multisystem trauma.
Methods. Features of infusions and transfusions were analyzed in 286 patients with multisystem trauma.
Results. The first stage of infusions and transfusions is antishock. In cases of severe bleeding it is important to prevent the cardiac arrest of «empty» heart, to maintain the circulating blood volume, cardiac output and blood pressure at a safe level (systolic blood pressure BP >80-90 mm Hg). The second stage is emergency surgery and surgical hemostasis (abdominal surgery, removal of intracranial hematoma, the most sparing reposition methods). At surgery, anyway, there is an additional blood loss related to surgery itself, but it is possible to compensate the blood loss with patient’s own blood, using machine methods of reinfusion. Infusions and transfusions are performed at general anesthesia. The third stage is the period of treatment in the intensive care unit. Infusions and transfusions should eliminate multiple disorders: volemic, oxygen transport, ionic, toxic, immune, energy and plastic. The goal of infusions and transfusions is to maintain the water-electrolyte metabolism; to treat the anemia and to ensure the efficient oxygen transport; microcirculation improvement; detoxification and metabolites excretion.
Conclusion. In multisystem trauma, the treatment success depends on the timely diagnosis, proper estimation of trauma severity, blood loss and general condition of the patient, infusions and transfusions depend on the treatment stage and injuries.
Clinical experience of using «Haemoblock» hemostatic solution in surgical practice
Abstract
Aim. The clinical assessment of safety and hemostatic effect of «Haemoblock» hemostatic solution for arresting active bleeding from abdominal cavity tissues at open and laparoscopic surgeries.
Methods. A total of 26 patients underwent surgeries. In 11 cases of acute calculous cholecystitis the drug was delivered to the bleeding surface during laparoscopic surgery by gauze soaked in «haemoblock» solution, which was introduced through 5 mm laparoscopic port (the first group). In 15 cases of acute adhesive intestinal obstruction, the drug was applied to the wound surface by moistened gauze during the open surgery (the second group).
Results. In 23 (88.5%) cases of 26, stable hemostatic effect was obtained. Mean hemostasis time was 2.09±0.2 minutes in the first group and 2.53±0,15 minutes in the second group. The first group of patients, hemostasis occurred within 1-3 minutes in 10 (90.9%) of 11 patients, no secondary bleeding and suppuration was noticed. One patient (9.1%) of the first group developed recurrent bleeding from the gallbladder bed, requiring repeated surgery. Two (13.3%) patients of the second group had recurrent bleeding, requiring additional re-use of the drug with an exposure of 4 min. After using «Haemoblock», no postoperative complications such as fistula formation of adhesions, as well as reactive abdominal cavity effusions, were observed. No toxic of allergic reactions, irritating effect on the surrounding tissues no influence on systemic hemostasis were reported.
Conclusion. «Haemoblock» is an effective local hemostatic that could be used as additional treatment to control parenchymal bleeding at abdominal and laparoscopic surgery.
