Оbjective: diagnosis of the a small intestine of bacterial overgrowth syndrome (SIBO) in patients with the failure of the bauginias valve (FBV) and after its surgical correction.
Material and methods. Patients of the studied groups were examined by means of direct and indirect methods of diagnostics of SIBO. Bacteriological research of an aspirate of aillium gut and other operational material was conducted. To all patients the hydrogen respiratory test was carried out and highquality reaction of urine to an indican was carried out. 50 patients are examined, from them 30 are inclu ded in the main group by which surgical correction of FBV – a bauginoplastik is made; 20 patients are included in group of control at which the illeocecal valve is well-founded. Patients of the main group were examined before operation and for the 7th and 45th days after a bauginoplastik.
Results. At all patients of the main group SIBO of varying severity is defined, at 80% of patients of SIBO was localized in distal part of the small intestine. Patients with normal function of the ileocecal valve a SIBO did not suffer. At 76% of patients revealed signs of a mezadenitisof a small intestine, the fact of a bacterial translocation at SIBO is confirmed. In 7 days after surgical correction of the bauginiasvalve normalization of a peak and background excretion of hydrogen was noted at 37% of patients. For the 45th days at all patients the hydrogen digram met standard.
Conclusions. The failure of the bauginiasvalveis obligatory followed by a small intestine of bacterial overgrowth syndrome, surgical correction is an effective method of correction of a SIBO at patients with FBV.
Objective: a comparative analysis of the results of the use of different surgical methods of treatment of patients with formed pancreatic cysts.
Material and methods. 108 patients with formed pancreatic cysts were treated and analysis of shortand long-term results of their surgical treatment was performed. Patients were divided into three groups depending on the type of surgical intervention: I – external drainage – 44 (40.7%), II – internal drainage –33 (30.6%), III – resection operations – 31 (28.7%).
Results and discussions. Marsupialization of cyst by laparotomy incision was performed in patients of I group (n = 44). 18 (40.9%) complications, 9 (20.5%) lethal cases were after operation. Anastomoses of cysts with the small intestine were mostly performed in II group (n = 33) – 21 (63.6%). 7 (21.2%) complications, 1 (3.0%) lethal case were after operation. Distal resections were performed in patients of III group (n = 31) in 16 (51.6%) cases. Duodenum-preserving resections were introduced for treatment of cyst of pancreas head – 12 (38.7%). When performing this type of operations we proposed nikelid titanium stents for the prevention of anastomosis stenosis and preoperative retrograde stenting of the common bile duct for the prevention of damage. 10 (32.3%) complications and no lethal cases were after operation. Immediate results were worse in patients of I group. 47 (43.5%) patients were analyzed in long-term period. The number of recurrences of the disease (13.3%) and long-term mortality (33.3%) prevailed in the group of patients undergoing internal drainage of cysts. Quality of life, level of mental and physical health, that was assessed using SF-36, were higher in group of patients with reactionary treatment.
Conclusion. The best immediate and long-term results were noted after resection operations, that enables to recommend their as the most optimal and radical method for treatment of patients with pancreatic cysts. Introducing of duodenum-preserving resections in case of pancreas head cyst improves the quality of patients life.
Study objectives: examine the frequency of genotypes and alleles of I/D polymorphism of gene ADRA2B of native people living in Mountain Shoria (the Shors), as well as their association with risk factors for cardiovascular diseases.
Material and methods. Overall 221 native people of Shoria were examined. The average age is
51.07 ± 1.46 among males, 52.93 ± 0.96 among females (p = 0.286). Anthropometric characteristics, lipid levels of blood and I/D polymorphism of ADRA2B were studied.
Results. DD genotype of the gene ADRA2B in the native population of the Shor people is associated with adiposis and high index of "waist/hip", hypertriglyceridemia. The average values of Quetelet index is higher in carriers of this genotype compared with carriers of genotype ID. Average waist indications in homozygous insertions were lower than those in homozygous deletions and heterozygotes. Patients with genotype DD have higher average levels of triglycerides, atherogenic index, cholesterol, very low density lipoproteins.
Conclusion. DD allele ADRA2B genotype is responsible for adiposis and high levels of TG among native population of Shoria.
The research objective is to determine the posterior probability of adverse cardiovascular events after elective coronary intervention in patients with ischemic heart disease (IHD) associated with type 2 diabetes, at high level of lipoprotein-associated phospholipase A2 (Lp-PLA2) in blood serum, as well as to find out the optimal separation point value for this predictor, which increase allows to identify high risk with accuracy.
Material and methods. The 12-month cohort observational study included 60 patients (78% of men and 22% of women) with IHD associated with type 2 diabetes, aged 48–78. At the beginning of the study, along with conventional diagnostic techniques typical of a specialized cardiology clinic, the state of carbohydrate and lipid metabolism was analyzed and the proinflammatory status was evaluated (including assessment of Lp-PLA2 concentration by ELISA). At the end of the study distant results of treatment were assessed. The following events were taken into account: death of cardiovascular events, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization (surgical, endovascular) due to restricture formation of a primary implanted stent or stricture formation of native coronary arteries, angina pectoris relapses.
Results and discussion. The link between adverse cardiovascular events after elective percutaneous coronary intervention in patients with IHD type 2 diabetes-associated and high concentration of Lp-PLA2 in blood serum has been identified. Variation of the decision rule threshold on the performance curve has allowed to take Lp-PLA2 concentration of 983 ng/ml as a separation point. Accuracy of twoclass classification (determination of the posterior probability of adverse cardiovascular events) after identifying such separation point was characterized by 80% sensitivity and 100% specificity.
Conclusion. The increase in the Lp-PLA2 concentration in blood serum (>983 ng/ml) may be considered as a predictor of adverse cardiovascular events after elective percutaneous coronary intervention in patients with IHD associated with type 2 diabetes.
A state of titanium oxide and oxynitride coatings on L316 steel has been studied before and after their contact with model biological fluids. Electrokinetic investigation in 1 mmol potassium chloride showed significant (more than 10 times) fall of magnitude of electrostatic potential of thin (200–300 nm) titanium films at pH changing in the range of 5–9 units during 2 h. Nevertheless, zeta-potential of all samples had negative charge under pH > 6.5. Long-term (5 weeks) contact of samples with simulated body fluid (SBF) promoted steel corrosion and titanium oxide and oxynitride films dissolution. On the other hand, sodium and chloride ions precipitation and sodium chloride crystals formation occurred on the samples. Of positive fact is an absence of calcification of tested artificial surfaces in conditions of long-term being in SBF solution. It is supposed decreasing hazard of fast thrombosis and loss of materials functional properties. According to in vitro experiment conducted, prospective biocompatibility of materials tested before and after their contact with SBF lines up following manner: Ti–O–N (1/3) > Ti–O–N (1/1), TiO2 > Steel. It may be explained by: 1) the corrosion-preventive properties of thin titanium oxide and oxynitride films;
2) a store of surface negative charge for Ti–O–N (1/3) film; 3) minor augmentation of mass and thickness of titanium films connected with speed of mineralization processes on the interface of solution/solid body. At the same time, initial (before SBF contact) differences of samples wettability became equal. Modifying effect of model biological fluids on physicochemical characteristics of materials tested (roughness enhancement, a reduction or reversion of surface negative potential, sharp augmentation of surface hydrofilicity) should took into account under titanium oxide and oxynitride films formation and a forecast of their optimal biological properties as the materials for cardiovascular stents.
The aim of this research was to assess the influence on metabolic processes of herbal extracts, used in diets with different fat content, in diabetes mellitus and insulin resistance model.
Material and methods. The experiments were performing on 90 noninbred male albino rats. Diabetes mellitus was modeling with twice-repeated intraperitoneal streptozotocine (30 mg/kg) injections. For the insulin resistance formation animals were fad meal with 30% fat content. Against the background rats were administering into the stomach nettle leafs (Urtica dioica L., 100 mg/kg), burdock roots (Arctium lappa L., 25 mg/kg) extracts or intraperitoneal insulin preparation Actrapide HM Penfill (3 mg/kg) daily during 10 days. During period of agents introduction one-half of animals continued to receive food with high fat content, the other half received diet with 8% fat content. The third rats group received only food with low fat content without extracts or insulin administration. In blood was measured the glucose, glycosylated hemoglobin, creatinine, urea, uric acid content, in liver homogenates – glycogen, protein content, aminotransferases and glucose-6phosphatase activity, in muscle homogenates – glycogen and protein content.
Results. After streptozotocine injections and diet with 30% fat content the blood glucose level became by 4.0–5.3 fold more than level of intact animals, increased the hemoglobin glycosylation, also creatinine, urea, uric acid blood content, in liver and muscle homogenates raised glycogen content, decreased protein quantity, in liver homogenates increased aminotranferases and glucose-6-phosphatase activity. In animals only feeding with 8% fat diminished hyperglycemia, creatinine blood retention, the liver glycogen content and recovered its protein resources. The nettle or burdock extracts administrating to animals that continued to receive high fat meal decreased the blood glucose, glycosylated hemoglobin and creatinine content, the liver glucose-6-phosphatase activity, increased the muscle protein content, the nettle extract also prevented from hyperuricemia and liver protein deficiency, the burdock extract caused the liver glycogen accumulation. In animals feeding with low fat meal the nettle extract caused hyperglycemia parameters regression and changed in the direction of the norm the liver and muscle glycogen content, the burdock extract decreased only hemoglobin glycosylation, both herbal extracts decreased the blood creatinine level and increased the muscle protein level. Independently of diet the nettle extract increased the insulin sensitivity after 60 and 120 min after insulin injection, the burdock extract – after 120 min.
Conclusion. The nettle and burdock extracts have in diabetes mellitus and insulin resistance model hypoglycemic action, prevent from hemoglobin glycosylation, improve creatinine excretion, recover the muscle sensitivity to insulin effect.
REVIEW AND LECTURES
The review presents the actual questions of the etiopathogenesis of central retinal vein occlusion and its branches. It was found that predictors of disease is a pathology of haemostasis, including asymptomatic gene mutations of coagulation factors and platelet receptors, chronic viral infections, rheumatological and oncological diseases, hypertension, metabolic disorders, smoking, physical inactivity, inflammatory diseases of the retinal and optic nerve, congenital and acquired abnormalities of retinal vascular, glaucoma.
The article also focused on the reasons for the formation of a blood clot. This is damage to the vascular wall, slowing the speed of blood flow in the vessel, hypercoagulation and hypofibrinolysis. Prevailing theories of the pathogenesis of retinal vein occlusion are analyzed. This is mechanical and theory “coag- ulopathy” whose arguments and counterarguments are discussed in detail. In addition, patients with reti- nal vein occlusion are needed in a multidisciplinary approach to the treatment of this disease. It is to im- prove the clinical and functional results of therapy and prevent the case of retrombosis.
