Особенности клеточного иммунитета и цитокинового репертуара у пациентов с метаболическим синдромом

In the formation of metabolic syndrome there is a change of the quantitative characteristics of immunocompetent cells and blood cytokine profile. According to our study, the elevated serum content of inflammatory cytokines (IL-6, IFNγ and TGF-β), in the cases of IL-10 decrease, was detected in patients with metabolic syndrome. The level of serum IL-1 inpatients with metabolic syndrome was within normal parameters. With it, there was a significant decrease in the percentage of blood CD3- and CD4-T-lymphocytes, and, conversely, an increase in the number of activated T (CD25+) and B (CD23+)-lymphocytes and monocytes (CD14+) has been in patients with metabolic syndrome. This revealed changes, is characterized by the presence of subclinical chronic inflammation in metabolic syndrome patients. It can be the result of compensatory immune responses developing in the weakening of adaptive immunity.В процессе формирования метаболического синдрома происходит изменение количественных характеристик иммунокомпетентных клеток и цитокинового профиля крови. Согласно данным проведенного исследования, у больных метаболическим синдромом регистрировалось повышенное сывороточное содержание провоспалительных цитокинов (IL-6, IFNγ и TGF-β) при снижении IL-10. Уровень сывороточного IL-1 у лиц с метаболическим синдромом находился в пределах нормы. Вместе с тем у пациентов с метаболическим синдромом имело место достоверное уменьшение содержания в крови СD3- и СD4-Т-лимфоцитов и, напротив, повышение числа активированных Т- (СD25+) и В (СD23+)-лимфоцитов, а также моноцитов (CD14+). Выявленные изменения характеризуют наличие у больных метаболическим синдромом субклинического хронического воспаления, которое может быть следствием компенсаторных иммунных реакций, развивающихся на фоне ослабления адаптивного иммунитета

ДИАГНОСТИЧЕСКОЕ ЗНАЧЕНИЕ ТРОМБОЦИТАРНОГО ФАКТОРА РОСТА PDGF-BB И ST2 ПРИ ОТТОРЖЕНИИ ТРАНСПЛАНТИРОВАННОГО СЕРДЦА

Aim: to determine the association between plasma concentrations of biomarkers (sCD40L, PDGF-BB, PlGF-1, ST2) with histochemical and immunohistochemical signs of heart rejection.Materials and methods. The study included 98 heart recipients aged from 12 to 69 (mean age 43 ± 14) years, of which 78 men. In 68 patients dilated cardiomyopathy was diagnosed, 30 recipients were diagnosed with coronary heart disease. The concentrations of placental growth factor (PlGF-1), platelet-derived growth factor (PDGF-BB), soluble CD40 ligand (sCD40L) were measured using xMAP technology. The concentrations of ST2 cardiac biomarker were measured by ELISA.Results. No correlation was found between the levels of biomarkers (sCD40L, PDGF-BB, PlGF-1, ST2) and gender, age and diagnosis. The rejection was diagnosed via biopsy in 49 biopsies taken from 37 recipients. 1A rejection was found in 25 patients (34 biopsies), 1B rejection was identifi ed in 2 patients (3 biopsies), 3A rejection was diagnosed in 4 patients. Immunohistochemical signs of humoral rejection were identifi ed in 3 patients. The combination of acute cellular and humoral rejection was found in 4 patients (5 biopsies). The PDGFBB level was measured at the same day as the biopsy was taken, and it was shown to be signifi cantly higher in patients with rejection (p = 0.02). Rejection frequency was signifi cantly higher in patients with high PDGF-BB level (≥2473.7 pg/ml, RR = 1.64 ± 0.23; 95% CI [1.03–2.61]). Rejection frequency increased to 2.11 ± 0.34 [95% CI [1.08–4.11]] in recipients with ST2 and PDGF-BB concentration higher than the median value. The highest predictive value for heart rejection can be reached by a panel of three biomarkers: sCD40L, PlGF-1 and ST2 (RR = 2.51 ± 0.38; 95% CI [1.18–5.3]).Conclusion. PDGF-BB has moderate predictive value for heart rejection. The highest predictive value for heart rejection was reached by a panel of three biomarkers: sCD40L, PlGF-1 and ST2.Цель: определить связь концентрации биомаркеров sCD40L, PDGF-BB, PlGF-1, ST2 в плазме крови реципиентов сердца с наличием и выраженностью гистохимических и иммуногистохимических признаков отторжения сердечного трансплантата.Материалы и методы. В исследование включены 98 пациентов с трансплантированным сердцем в возрасте от 12 до 69 (43 ± 14) лет, из них 78 мужчин. У 68 реципиентов до трансплантации сердца была диагностирована дилатационная кардиомиопатия, у 30 – ишемическая болезнь сердца. Концентрацию плацентарного фактора роста (PlGF-1), фактора роста тромбоцитов (PDGF-BB), растворимой формы лиганда CD40 (sCD40L) измеряли с использованием мультиплексной технологии; концентрацию стимулирующего фактора роста ST2 – с помощью иммуноферментного анализа.Результаты. Концентрация каждого биомаркера не зависела от пола, возраста и диагноза до трансплантации. У 37 пациентов (по результатам 49 биопсий) были диагностированы признаки отторжения. Гистохимические признаки острого клеточного отторжения – у 30 реципиентов (в 41 биоптате): 1А – у 25 пациентов (в 34 биоптатах), 1В – у двух пациентов (в трех биоптатах), 3А – у четырех пациентов. Иммуногистохимические признаки антителоопосредованного отторжения выявлены у трех пациентов. Сочетание острого клеточного и гуморального отторжения обнаружено у четырех пациентов (в пяти биоптатах). Концентрация PDGF-BB, измеренная в день эндомиокардиальной биопсии, была достоверно выше у пациентов с отторжением (p = 0,02). У реципиентов сердца с уровнем PDGF-BB выше медианы (2473,7 пг/мл) риск отторжения был в 1,64 раза выше, чем у пациентов с уровнем ниже медианы. У реципиентов с концентрацией и ST2, и PDGF-BB, превышающей значения медианы, относительный риск отторжения возрастал до 2,11 ± 0,34 [95% ДИ 1,08–4,11]. Наибольшей диагностической значимостью в отношении отторжения трансплантата обладала панель из трех биомаркеров (sCD40L, PlGF-1, ST2): RR = 2,51 ± 0,38 [95% ДИ 1,18–5,3].Заключение. PDGF-BB обладает умеренной прогностической значимостью в отношении отторжения трансплантированного сердца. Наибольшей диагностической значимостью обладает панель из трех биомаркеров: sCD40L, PlGF-1, ST2

Сравнительный анализ диагностической значимости панелей биомаркеров у реципиентов сердца в отдаленные сроки после трансплантации

Aim. To perform comparative analysis of the diagnostic efficacy of sCD40L, PDGF-BB, VEGF-A and ST2 in recipients with cardiac rejection in different periods after transplantation. Materials and methods. The study included 144 cardiac recipients aged from 12 to 71 (mean age 44 ± 14) years old, among those 112 were men. Venous blood plasma taken on the same day with endomyocardial biopsy was used for the study. The concentrations of soluble CD40 ligand (sCD40L), vascular endothelial growth factor (VEGF-A), platelet-derived growth factor (PDGF-BB) were measured using xMAP technology. The concentrations of ST2 were measured by ELISA. Results. Men had significantly higher levels of ST2 and VEGF-A compared to women (p = 0.03). No correlation was found between the levels of biomarkers (sCD40L, PDGF-BB, VEGF-A, ST2) and age, diagnosis before transplantation, presence of arterial hypertension and diabetes mellitus. Comparative analysis of the biomarkers’ levels didn’t show significant difference between patients with heart transplant rejection and without it in the first month and in the first year after transplantation. The ST2 level was significantly higher in patients with heart rejection (p = 0.01) in the long term period (1–5 years) after transplantation compared to patients without rejection. Relative risk of cardiac transplant rejection was significantly higher in patients with high (>22.8 ng/ml) ST2 level (RR = 2.59 ± 0.33; Se – 35%, Sp – 93%). However, its combination with other biomarkers improved their diagnostic value. Relative risk for panel including ST2, VEGF-A and PDGF-BB 3.47 ± 0.55, Se – 57%, Sp – 91%; relative risk for panel including ST2, sCD40L and PDGF-BB was 3.75 ± 0.59, Se – 50%, Sp – 92%. The highest diagnostic efficacy for the heart transplant rejection was reached by a panel of biomarkers that included ST2 and PDGF-BB (RR = 5.0 ± 0.56 [95% CI 1.68–14.92], Se – 63%, Sp – 94%). Conclusion. ST2 had the biggest diagnostic value for heart transplant rejection in the long term period after heart transplantation. Its usage as a part of complex tests with other biomarkers improves the sensitivity of noninvasive diagnosis of the cardiac rejection. The highest diagnostic significance for cardiac transplant rejection in the long term period was shown by a panel of ST2 and PDGF-BB.Цель. Выполнить сравнительный анализ диагностической эффективности sCD40L, PDGF-BB, VEGF-A и ST2 в составе панелей биомаркеров при отторжении трансплантированного сердца в различные сроки после трансплантации. Материалы и методы. В исследование включены 144 реципиента сердца в возрасте от 12 до 71 (44 ± 14) года, из них 112 мужчин. Концентрацию цитокинов измеряли в плазме периферической крови пациентов, взятой в день эндомиокардиальной биопсии. Уровень растворимой формы лиганда CD40 (sCD40L), фактора роста эндотелия сосудов (VEGF-A), фактора роста тромбоцитов (PDGF-BB), измеряли с использованием мультиплексной технологии; уровень стимулирующего фактора роста ST2 – с помощью иммуноферментного анализа. Результаты. Уровень ST2 и VEGF-A был достоверно выше у мужчин, чем у женщин (p = 0,03). Уровни исследуемых биомаркеров не зависели от возраста, диагноза до трансплантации сердца (ТС), наличия артериальной гипертонии, сахарного диабета II типа. Сравнительный анализ уровней биомаркеров не показал достоверной разницы у пациентов с наличием отторжения сердечного трансплантата и без такового в первый месяц и в первый год после ТС. Концентрация ST2 была достоверно выше у пациентов с отторжением сердца, чем без такового, в отдаленные сроки (1–5 лет) после ТС (p = 0,01). Относительный риск развития отторжения трансплантированного сердца в отдаленные сроки после ТС у пациентов с концентрацией ST2, превышающей значение медианы (22,8 нг/мл), в 2,6 раза выше, чем у пациентов с концентрацией цитокина ниже медианы (чувствительность – 35%, специфичность – 93%). ST2 в составе панелей биомаркеров увеличивает их диагностическую значимость: для панели, включающей ST2, PDGF-BB и VEGF-A, относительный риск составлял 3,47 ± 0,55 (чувствительность – 57%, специфичность – 91%); для панели, включающей ST2, PDGF-BB и sCD40L – 3,75 ± 0,59 (чувствительность – 50%, специфичность – 92%) Сочетание ST2 и PDGF-BB обладало наибольшей диагностической значимостью (RR = 5,00 ± 0,56 [95% ДИ 1,68–14,92]; чувствительность – 63%, специфичность – 94%). Заключение. Наибольшей диагностической значимостью при отторжении трансплантированного сердца в отдаленные сроки после трансплантации обладает ST2, и его применение в составе комплексных тестов с другими биомаркерами позволяет улучшить чувствительность неинвазивной диагностики отторжения. Наибольшей диагностической значимостью в отдаленные сроки после ТС обладает панель из двух биомаркеров: ST2 и PDGF-BB

Epidemiological significance of chronic pharyngitis, nasopharyngitis, sinusitis, and rhinitis in Moscow and the Russian Federation in 1996 to 2009

Objective: to study trends in the incidence and prevalence of chronic pharyngitis, nasopharyngitis, sinusitis, and rhinitis (CPNSR) in differentage groups in Moscow and the Russian Federation (RF) in the period 1996 to 2009.Materials and methods. The epidemic significance of CPNSR in Moscow and the RF was estimated, by analyzing the records available in the annual official statistical sources (Form No. 12).Results. The incidence of CPNSR in Moscow in the study period remains lower than those in the RF. Its prevalence among the population in the city and in the country as a whole shows a significant increasing trend. Among the adolescents in both Moscow and the RF, the incidence of CPNSR is higher than that in children and constitutes 24.4 and 31.6 versus 3.3 and 21.8 per 10,000 population, respectively. The childrenand adolescents in the RF are the highest risk groups in the incidence of CPNSR. In 2009, its prevalence rates in Moscow and the RF were 99.5 and 121.3 per 10,000, respectively; which were well above those in 2007 (81.2 and 117.5 per 10,000, respectively).Conclusion. The high incidence and prevalence rates for CPNSR remain high in all population strata in Moscow and the RF, which may be associated with decreased diagnostic alertness and inadequate treatment for upper airway diseases.</p

Learning motivation of first-year students of a technical university

The concepts “motive” and “motivation” and their role in the learning process of the technical university are analyzed. The following types of motives were distinguished: internal learning motivation related to learning activities and their content and external learning motivation not related to learning activities and their content but determined by external factors and circumstances. Learning motivation is associated with various changes that occur in students during the learning process. To identify the motivation in firstyear students, they were tested. Driving motives were identified. The results showed that students prefer real learning motives (to use acquired knowledge in life, to continue successful training in subsequent courses, to get good marks, to acquire deep knowledge and intellectual satisfaction). The authors examined motivating methods and techniques. Motivation is a tool used to improve the learning process

Architecture of the Multi-agent Resource Conversion Processes Extended with Agent Coalitions

Pretty often there is a process visualization in one's mind before the process is implemented in form of a simulation model. The main purpose of this visualization is the certain improvement of an imperfect or ineffective process, or the estimation of the influence of various impacts. Most of the time the simulation systems provide a certain benefit for us, especially when the process develops in a predefined way, no matter how complex it is. But sometimes there are situations when the decision making persons have to interact between each other and make a decision with consideration of the other person's opinion. Moreover, that may have conflicts in case they use the same resources or they are focused on a common goal by using different approaches (and again, same resources). Anyway, this sort of behavior has to be modelled as well. In this work we are presenting the apparatus of the resource conversion processes for the distributed simulation system BPsim.MAS. We will present the advantages of the software, the technologies lying under the hood and some recent additions that were implemented for the definition of agent coalitions. This is something which helps us create the simulation models of the complex systems and behavior scenarios, when multiple agents interact with each other. At the end of the work we suggest a sample implementation of the system on the basis of a network of petrol stations, that relies on presented apparatus. We also compare our results with the ones achieved with the simulation model, based on the networks of requirements and capabilities. © 2017 The Authors

Hybrid Agents Implementation for the Control of the Construction Company

Planning the project duration together with separate works is an essential element of managing the construction. The final duration depends on multiple factors, including the funds, customer requests, and capabilities of the construction company. In order to avoid additional costs in penalties or additional expenses, the management needs to estimate the real construction duration in advance, before the contract is signed. Further on, these terms need to be monitored both in whole and for the specific jobs in order to be able to edit further stages with regard of the remaining time, resources and used resources ratio. The development of a decision support system for the construction company is a pressing problem due to the growing demand in decision making persons' labor automation in planning and monitoring the construction processes. The paper presents the model and the application experience for such a system. © 2017 The Authors
