Introduction. The initial assessment of prognosis is of particular importance in determining the management of patients with B-cell chronic lymphocytic leukemia and the choice of specific therapy. The aim is to analyze the risk factors for failure to achieve a complete response to the bendamustine±rituximab treatment regimen in patients with B-cell chronic lymphocytic leukemia. Materials and methods. Twenty-two patients undergoing treatment for B-cell chronic lymphocytic leukemia (B-CLL) progression were included in the study. Response to treatment was assessed on the 56th day, categorized as complete, partial, or no response. Patients were divided into three groups based on their response: group I (n=6) included patients who showed a complete response after receiving bendamustine±rituximab; group II (n=11) included patients who achieved a partial response; and group III (n=5) consisted of patients with no response. Risk factors for chemotherapy resistance, as well as general and biochemical blood counts, were evaluated and subjected to statistical analysis. Results: Stage III (C) and IV (C) according to the Rai, Binet classification were recorded in 33.2% of patients with a complete response to chemotherapy, in 36.4% of patients with a partial response to chemotherapy, and in 60% of patients with no response to specific treatment. A decrease in hemoglobin level below 100 g/L was recorded only in patients with a partial response and no response, namely in 4 (36%) patients of group II and 1 (20%) patient of group III. On day 56, in patients of group II who received a partial response, there was a direct correlation between the level of leukocytes in the hemogram and the activity of aspartate aminotransferase (r=0.71; p=0.01) and the content of total bilirubin (r=0.63; p=0.03) in the biochemical blood test. After 2 courses of chemotherapy in patients of group III, a direct correlation of high strength between the level of leukocytes in the hemogram and the activity of aspartate aminotransferase (r=0.93; p=0.02) and alanine aminotransferase (r=0.93; p=0.02) in the biochemical blood test was found. The bendamustine±rituximab chemotherapy regimen has a high safety profile.
导言对预后的初步评估对于确定 B 细胞慢性淋巴细胞白血病患者的治疗方案和特定疗法的选择尤为重要。本文旨在分析 B 细胞慢性淋巴细胞白血病患者在接受苯达莫司汀±利妥昔单抗治疗方案后未能获得完全应答的风险因素。材料与方法研究纳入了22名正在接受治疗的B细胞慢性淋巴细胞白血病(B-CLL)进展期患者。治疗反应在第 56 天进行评估,分为完全反应、部分反应或无反应。根据患者的反应分为三组:I组(6人)包括接受苯达莫司汀±利妥昔单抗治疗后出现完全反应的患者;II组(11人)包括出现部分反应的患者;III组(5人)包括无反应的患者。对化疗耐药的风险因素以及一般和生化血液计数进行了评估和统计分析。结果根据 Rai 和 Binet 的分类,33.2% 的患者对化疗完全有反应,36.4% 的患者对化疗部分有反应,60% 的患者对特定治疗无反应,均为 III 期(C)和 IV 期(C)。只有部分反应和无反应患者的血红蛋白水平下降到 100 克/升以下,即第二组的 4 名患者(36%)和第三组的 1 名患者(20%)。第 56 天,在获得部分应答的 II 组患者中,血液图中的白细胞水平与血液生化检验中的天冬氨酸氨基转移酶活性(r=0.71;p=0.01)和总胆红素含量(r=0.63;p=0.03)之间存在直接相关性。第三组患者经过两个疗程的化疗后,发现血象中的白细胞水平与血液生化检验中的天冬氨酸氨基转移酶活性(r=0.93;p=0.02)和丙氨酸氨基转移酶(r=0.93;p=0.02)之间存在高度的直接相关性。苯达莫司汀±利妥昔单抗化疗方案具有较高的安全性。

SLEEP QUALITY AND AVOIDANCE BEHAVIOR IN COMBATANTS WITH POST-TRAUMATIC STRESS DISORDER 患有创伤后应激障碍的战斗人员的睡眠质量和回避行为
D.I. Boiko, O.V. Mats, O. I. Shkidchenko
Introduction. Post-traumatic stress disorder (PTSD) is often characterized by various symptoms that result in behavioral changes in patients, among which sleep disturbances and avoidant behavior are commonly observed. However, despite evidence indicating a complex bilateral relationship between emotions and sleep, only few studies have explored the associations between sleep disturbances and avoidant behavior in the context of PTSD. The aim of the study is to assess the severity of avoidant behaviour and insomnia in combatants with posttraumatic stress disorder. Materials and methods. We conducted a clinical study of 45 combatants who were divided into 2 groups: group 1 (n=24) included combatants with PTSD; group 2 (n=21) consisted of combatants without PTSD. The Pittsburgh Sleep Quality Questionnaire was used to analyse sleep quality, namely subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, sleep medication use, and daily dysfunction. Avoidance behavior was measured using a multidimensional experience avoidance questionnaire. Results. We found that group 1 demonstrated worse subjective sleep quality (p=0.002), longer sleep latency (p<0.001), lower sleep efficiency (p=0.019) and more severe sleep disturbances (p<0.001). There were no statistically significant differences between the groups in terms of sleep duration, severity of sleeping pills use, and daily dysfunction. The overall severity of sleep quality disorders was higher in group 1 compared to group 2 (p<0.001). Avoidance behavior (p=0.007) and repression and denial (p<0.001) were more pronounced in group 1 compared to group 2. At the same time, group 1 had lower stress endurance (p<0.001). The overall level of experiental avoidance in group 1 was higher than in group 2 (p<0.001). Numerous associations between sleep quality characteristics and experiental avoidance were found as well. Conclusions. The study has revealed that combatants with PTSD have more pronounced manifestations of behavioural avoidance, repression and denial, as well as a lower level of stress endurance. At the same time, combatants with PTSD demonstrate a deterioration in the subjective quality of sleep, a decrease in its effectiveness and an increase in the severity of its disturbances. It has been found that avoidance behavior in combatants has numerous connections with the characteristics of sleep quality that may be suggested as a potential factor for improving psychotherapeutic interventions.
简介创伤后应激障碍(PTSD)通常以各种症状为特征,这些症状会导致患者的行为发生变化,其中睡眠障碍和回避行为是常见的症状。然而,尽管有证据表明情绪和睡眠之间存在复杂的双边关系,但只有少数研究探讨了创伤后应激障碍中睡眠障碍和回避行为之间的关联。本研究旨在评估创伤后应激障碍患者的回避行为和失眠的严重程度。材料和方法。我们对 45 名战斗人员进行了临床研究,他们被分为两组:第一组(24 人)包括患有创伤后应激障碍的战斗人员;第二组(21 人)包括未患有创伤后应激障碍的战斗人员。采用匹兹堡睡眠质量问卷分析睡眠质量,即主观睡眠质量、睡眠潜伏期、睡眠持续时间、睡眠效率、睡眠障碍、睡眠药物使用和日常功能障碍。回避行为采用多维经验回避问卷进行测量。结果显示我们发现,第一组的主观睡眠质量更差(p=0.002),睡眠潜伏期更长(p<0.001),睡眠效率更低(p=0.019),睡眠障碍更严重(p<0.001)。在睡眠时间、服用安眠药的严重程度和日常功能障碍方面,组间差异无统计学意义。与第二组相比,第一组患者睡眠质量障碍的总体严重程度更高(P<0.001)。与第二组相比,第一组的回避行为(p=0.007)以及压抑和否认(p<0.001)更为明显。同时,第一组的压力耐受力较低(p<0.001)。第 1 组的整体经验回避水平高于第 2 组(P<0.001)。睡眠质量特征与体验性回避之间也存在许多关联。结论研究显示,患有创伤后应激障碍的战斗人员有更明显的行为回避、压抑和否认表现,压力耐受水平也更低。与此同时,患有创伤后应激障碍的战斗人员的主观睡眠质量下降,睡眠效率降低,睡眠障碍的严重程度增加。研究发现,战斗员的回避行为与睡眠质量的特征有许多联系,可作为改善心理治疗干预的潜在因素。

ACUTE MYOCARDIAL INFARCTION DURING VRD CHEMOTHERAPY IN A PATIENT WITH MULTIPLE MYELOMA: A CLINICAL CASE 多发性骨髓瘤患者在 Vrd 化疗期间发生急性心肌梗死:临床病例
V. Ostrovskyi
Acute myocardial infarction is a critical condition associated with significant morbidity and mortality rates. Myocardial infarction-related acute myocardial injury is characterized by a rapid elevation and subsequent decline in cardiac troponin concentration. According to the relevant data patients with multiple myeloma are in a high-risk category for venous and arterial thrombosis. Therefore, the incidence of cardiovascular complications, which include myocardial infarction, in these patients is higher than in the general population. The development of metaplastic anemia further compounds this risk by diminishing myocardial oxygen supply. Moreover, chemotherapy for oncohematological diseases carries the potential for cardiotoxic cardiovascular complications. Immunomodulator drugs like Thalidomide and Lenalidomide, frequently utilized in multiple myeloma treatment, have been associated with Lenalidomide-induced myocardial infarction—a prevalent adverse effect. The use of proteasome inhibitors such as Bortezomib and Carfilzomib poses an increased risk for myocardial infarction development. This clinical case presents an instance of acute myocardial infarction in a multiple myeloma patient during low cumulative chemotherapy dosage, comprising Lenalidomide and Bortezomib. It underscores the necessity for enhanced clinical, instrumental, and laboratory monitoring before each specific chemotherapy course in high-risk multiple myeloma patients. Such monitoring facilitates the early detection of chemotherapy-induced cardiotoxic effects, allowing for timely intervention and management.
急性心肌梗死是一种危重病,发病率和死亡率都很高。与心肌梗死相关的急性心肌损伤的特点是心肌肌钙蛋白浓度迅速升高并随后下降。根据相关数据,多发性骨髓瘤患者属于静脉和动脉血栓形成的高危人群。因此,这些患者心血管并发症(包括心肌梗死)的发病率高于普通人群。变应性贫血的发生会减少心肌供氧,从而进一步加剧这一风险。此外,针对肿瘤性血液病的化疗也有可能引发心血管毒性并发症。多发性骨髓瘤治疗中常用的免疫调节剂药物,如沙利度胺和来那度胺,与来那度胺诱发的心肌梗死有关,这是一种普遍的不良反应。使用蛋白酶体抑制剂(如硼替佐米和卡非佐米)会增加发生心肌梗死的风险。本临床病例介绍了一名多发性骨髓瘤患者在使用来那度胺和硼替佐米的低累积化疗剂量期间发生急性心肌梗死的病例。这突出表明,在对高危多发性骨髓瘤患者进行每个特定化疗疗程之前,有必要加强临床、仪器和实验室监测。这种监测有助于及早发现化疗引起的心脏毒性反应,以便及时干预和处理。

CHANGES IN CIRCADIAN CHARACTERISTICS OF PATIENTS WITH PARKINSON DISEASE AFTER CORRECTION OF POOR SLEEP QUALITY USING MELATONIN: AN OPEN-LABEL CONTROLLED RANDOMISED TRIAL 使用褪黑素纠正睡眠质量差后帕金森病患者昼夜节律特征的变化:一项开放标签随机对照试验
A. Shkodina
Introduction. Recent studies are increasing the amount of evidence suggesting that the circadian system is disrupted in Parkinson's disease that can lead to poor sleep. Currently, international guidelines for managing non-motor symptoms of Parkinson's disease do not have recommendations with proven efficacy, but only methods with potential benefit. Two of the most widely available methods for correcting poor sleep quality in patients with Parkinson's disease in Ukraine are sleep hygiene training, also known as somnoeducation, and melatonin administration. The aim of the study is to compare the state of circadian characteristics before and after the correction of poor sleep quality in patients with Parkinson's disease in the context of sleep hygiene and an integrated approach with the implementation of chronotherapy using melatonin. Materials and methods. We conducted a clinical trial at the Centre for Patients with Parkinson's Disease and Other Neurodegenerative Diseases, which included 34 patients with poor sleep quality who were randomised into 2 groups: group 1a (n = 17) consisted of patients with Parkinson's disease who followed sleep hygiene rules and received chronotherapy; group 1b (n = 17) involved patients with Parkinson's disease who followed sleep hygiene rules but did not take any medications to improve sleep. Circadian characteristics were analysed using the Munich Chronotype Questionnaire. Results. Our study has found that the correction of poor sleep quality by introducing sleep hygiene into the treatment process of patients with Parkinson's disease demonstrates a shift in the time of sleep onset and mid-sleep to earlier, accompanied by a shift in chronotypes towards earlier, as well as an increase in sleep duration against a decrease in the time spent in bed, which led to an increase in the average actual sleep efficiency. At the same time, melatonin supplementation helps to reduce sleep latency in Parkinson's disease. Conclusions. Adherence to sleep hygiene recommendations contributes to changes in circadian characteristics and improves sleep efficiency in patients with Parkinson's disease, regardless of melatonin administration. Additional use of melatonin to correct the quality of sleep for 1 month is accompanied by a reduction in the sleep latency period.
导言。最近的研究越来越多地表明,帕金森病患者的昼夜节律系统紊乱会导致睡眠不佳。目前,治疗帕金森病非运动症状的国际指南并没有推荐经证实有效的方法,而只有一些具有潜在益处的方法。在乌克兰,纠正帕金森病患者睡眠质量差的两种最广泛的方法是睡眠卫生训练(也称为睡眠教育)和褪黑素给药。本研究的目的是比较帕金森病患者在通过睡眠卫生训练和使用褪黑素进行时序疗法的综合方法纠正睡眠质量低下前后的昼夜节律特征。材料和方法我们在帕金森病和其他神经退行性疾病患者中心开展了一项临床试验,其中包括34名睡眠质量差的患者,他们被随机分为两组:1a组(n = 17)包括遵守睡眠卫生规则并接受时间疗法的帕金森病患者;1b组(n = 17)包括遵守睡眠卫生规则但未服用任何改善睡眠药物的帕金森病患者。昼夜节律特征采用慕尼黑时间型问卷进行分析。研究结果我们的研究发现,通过在帕金森病患者的治疗过程中引入睡眠卫生来纠正睡眠质量差的问题,显示了睡眠开始时间和睡眠中期时间的提前,同时伴随着昼夜节律的提前,以及睡眠时间的延长和卧床时间的减少,这导致了平均实际睡眠效率的提高。同时,补充褪黑素有助于缩短帕金森病患者的睡眠潜伏期。结论无论是否服用褪黑素,遵守睡眠卫生建议都有助于改变帕金森病患者的昼夜节律特征并提高睡眠效率。在连续一个月使用褪黑素改善睡眠质量的同时,睡眠潜伏期也会缩短。

ANALYSIS OF REGULATORY AND LEGAL SUPPORT FOR THE PREVENTION OF DIABETES MELLITUS IN CHILDREN 对预防儿童糖尿病的法规和法律支持的分析
K. V. Pocheniuk, I.A. Holovanova
Diabetes mellitus has become one of the most prevalent chronic diseases in childhood today. International forecasts suggest that the incidence of diabetes will continue to rise in the coming decades, leading to a lifelong burden for millions of children worldwide. Therefore, prediction, prevention, and optimal treatment of diabetes, as well as early prevention of serious long-term complications, remain essential. Providing highly qualified medical care to diabetic patients is a crucial step in preventing the development of complications. The purpose of this article is to review existing research on diabetes prevention strategies for children, considering the different levels of medical care support available. Materials and Methods. This study investigates the organization of preventive care for children with diabetes in Ukraine. Researchers employed three key methods: bibliosemantic analysis, content analysis focused on analyzing Ukraine relevant regulations and legal frameworks, and the method of systemic approach and analysis to gain a comprehensive understanding of how preventive care is currently organized for children with diabetes in Ukraine. Results. In Ukraine, preventive measures and the provision of medical care to pediatric patients with diabetes in the past years and today are regulated by a number of documents and orders of the Ministry of Health. As part of the Comprehensive Program “Diabetes Mellitus” (1999) and in accordance with the Order of the Ministry of Health of Ukraine “On Improving the Organization of Providing Endocrinological Care to the Population of Ukraine” (2006), the State Register of Patients with Diabetes Mellitus (SYNADIAB) was created. The next step was the approval of the State Target Program “Diabetes Mellitus”. Subsequently, the Project of the national program “Health 2020: Ukrainian Dimension” became an effective tool, which outlined the main principles of the program implementation in the “Endocrinology” section for 2013-2020. It defined measures at all stages of diabetes prevention, such as primary prevention, which consists of maintaining and strengthening the general state of health and preventing or delaying the development of diabetes; secondary prevention should improve early detection of diabetes mellitus; tertiary prevention, which ensures the effectiveness and safety of treatment of children with diabetes to prevent the development of long-term complications. Today, the guidelines for the management of children with diabetes mellitus have been continued in such documents as “Diabetes Mellitus in Children”, Evidence-Based Clinical Guidelines (2023) and Standards of Care (2023). Conclusion. Diabetes mellitus is a chronic disease that ranks third in prevalence after cardiovascular and cancerous diseases and second in the structure of endocrine diseases after thyroid gland pathology. Today, the prevalence of diabetes mellitus among children is constantly increasing and, therefore, solving the issue
糖尿病已成为当今儿童最普遍的慢性疾病之一。国际预测显示,未来几十年糖尿病发病率将继续上升,给全球数百万儿童带来终身负担。因此,对糖尿病的预测、预防和最佳治疗,以及早期预防严重的长期并发症仍然至关重要。为糖尿病患者提供高水平的医疗护理是预防并发症发生的关键一步。本文旨在回顾现有的儿童糖尿病预防策略研究,同时考虑到不同级别的医疗护理支持。材料和方法。本研究调查了乌克兰儿童糖尿病预防护理的组织情况。研究人员采用了三种主要方法:书目语义分析法、侧重于分析乌克兰相关法规和法律框架的内容分析法以及系统方法和分析法,以全面了解乌克兰目前如何组织儿童糖尿病患者的预防保健工作。结果。在乌克兰,过去几年和现在为儿童糖尿病患者提供的预防措施和医疗服务由卫生部的一系列文件和命令进行规范。作为 "糖尿病 "综合计划(1999 年)的一部分,并根据乌克兰卫生部 "关于改善向乌克兰居民提供内分泌治疗的组织 "的命令(2006 年),建立了国家糖尿病患者登记册(SYNADIAB)。下一步是批准国家 "糖尿病 "目标方案。随后,国家计划 "健康 2020:该项目概述了 2013-2020 年在 "内分泌学 "领域实施该方案的主要原则。它确定了糖尿病预防各个阶段的措施,如一级预防,包括保持和加强总体健康状况,预防或推迟糖尿病的发展;二级预防应改善糖尿病的早期发现;三级预防,确保儿童糖尿病患者治疗的有效性和安全性,以防止长期并发症的发展。如今,《儿童糖尿病》、《循证临床指南(2023 年)》和《护理标准(2023 年)》等文件延续了儿童糖尿病管理指南。结论糖尿病是一种慢性疾病,其发病率仅次于心血管疾病和癌症,位居第三位,在内分泌疾病结构中仅次于甲状腺病变,位居第二位。如今,糖尿病在儿童中的发病率不断上升,因此,解决与这种疾病相关的问题是国家医疗保健系统的优先任务之一。这是因为,在不同人群中,糖尿病与导致丧失工作能力、残疾和死亡的并发症的高风险相关。在最新医疗技术的基础上,组织高质量的医疗护理和建立有效的预防系统至关重要。糖尿病需要关注。了解该疾病的风险和预防方法,可以通过及时治疗大大增加保护和健康长寿的机会。

The human circulatory system has historically captivated researchers in the field of medicine. Modern medicine, however, has moved beyond identifying a single crucial element, such as the heart or venous system, for maintaining blood flow. Instead, it emphasizes a more analytical approach, focusing on the interconnected functioning of all components within the system. The aim of this work is to analyze the existing methods of studying blood microcirculation and to improve the technology of capillaroscopy, technical means of raster microphotography to determine the physiological state and disorders of capillary circulation. To achieve this objective, we address the following tasks: analyzing existing non-invasive methods for studying the human vascular system; enhancing the optical capillaroscopy method through the utilization of modern high-resolution digital cameras, computer, and multimedia equipment, along with appropriate software for analyzing electronic images; developing a technological scheme and equipment design for digital microphotography of capillaries in the periungual region of the upper extremities; providing software solutions for registering and analyzing digital microphotographic images obtained through capillaroscopy; conducting experimental studies to explore the structure and properties of capillaries utilizing the developed technologies and equipment. Magnetic resonance imaging (MRI) enables the comprehensive evaluation of both anatomical and functional aspects of blood flow. Magnetic resonance angiography (MRA) capitalizes on the distinction between the signal emitted by moving tissue (blood) and that of surrounding stationary tissue, facilitating the acquisition of vascular images without the need for radiopaque contrast agents. Ultrasonography integrates Doppler and conventional ultrasound techniques, providing physicians with insights into blood vessel structure and blood flow dynamics. Traditional ultrasound employs sound waves that are imperceptible to the human ear and bounce off blood vessels, while Doppler ultrasound measures the velocity of sound wave reflection from moving elements.

人体循环系统历来吸引着医学领域的研究人员。然而,现代医学已不再局限于确定心脏或静脉系统等维持血液流动的单一关键要素。取而代之的是,它强调一种更具分析性的方法,重点关注系统内所有组成部分的相互关联功能。这项工作的目的是分析研究血液微循环的现有方法,并改进毛细血管镜技术,即利用光栅显微照相技术手段来确定毛细血管循环的生理状态和紊乱情况。为实现这一目标,我们将完成以下任务:分析现有的研究人体血管系统的非侵入性方法;通过利用现代高分辨率数码相机、计算机和多媒体设备以及适当的电子图像分析软件,改进光学毛细血管镜检查方法;开发用于对上肢掌周毛细血管进行数字显微摄影的技术方案和设备设计;提供用于登记和分析通过毛细血管镜检查获得的数字显微摄影图像的软件解决方案;利用开发的技术和设备开展实验研究,探索毛细血管的结构和特性。磁共振成像(MRI)可对血流的解剖和功能方面进行全面评估。磁共振血管造影术(MRA)利用运动组织(血液)发出的信号与周围静止组织发出的信号之间的区别,无需使用不透射线的造影剂即可获取血管图像。超声造影结合了多普勒和传统超声技术,可让医生深入了解血管结构和血流动态。传统超声波利用人耳无法感知的声波从血管反弹,而多普勒超声波则测量声波从移动部件反射的速度。眼底镜检查是标准眼科检查的基本组成部分,是诊断眼部疾病和评估血管状况的重要工具。此外,眼底镜还有助于诊断自身免疫性疾病。毛细血管镜可对全身和区域性微循环障碍进行全面评估,有助于确定组织代谢的特征。毛细血管功能失调会造成循环障碍,导致血液淤滞、新陈代谢失调和免疫力下降,从而加重现有疾病,并使人容易患上新的疾病。光学电脑毛细血管镜提供了一种可视化、检查和存档毛细血管图像的无创手段,使临床医生能够对血液微循环做出明智的评估。使用一名接受胰岛素治疗长达 10 年的 II 型糖尿病患者的甲床毛细血管,对优化的硬件和软件毛细血管镜系统进行了实验验证。这项研究强调了利用高分辨率相机传感器和现代图像处理计算工具完善和改进光学毛细血管镜检查方法的重要性。

IMPACT OF QUERCETIN ON PATHOMORPHOLOGICAL CHARACTERISTICS OF MANDIBULAR BONE IN RATS FOLLOWING ITS FRACTURE UNDER CHRONIC ALCOHOL INTOXICATION 槲皮素对慢性酒精中毒大鼠下颌骨骨折后病理形态特征的影响
K.I. Nestulia, I.I. Starchenko, V.O. Kostenko
This study aims at investigating the impact of water-soluble form of quercetin on the pathomorphological characteristics of the mandibular bone in rats following its incomplete fracture under chronic alcohol intoxication was investigated. Fourteen white male Wistar rats weighing 190-240 g were randomly divided into two groups: Group 1 comprised rats with incomplete mandibular fractures under chronic alcohol intoxication; animals in Group 2 received daily intraperitoneal injections of water-soluble quercetin (corvitin) in a dose of 10 mg/kg of quercetin for 14 days following the injury induction. It has been shown that chronic alcohol intoxication hinders reparative regeneration of bone tissue after an incomplete mandibular fracture, and is accompanied by a decrease in the relative amount of reticulofibrous bone tissue and fibroblastic cellular elements at the injury site, especially mature fibroblasts, as well as by delayed maturation of granulation tissue. Under experimental conditions, quercetin administration significantly contributed to normalizing the regenerative process by the 14th day of the posttraumatic period. This normalization was evidenced by increased relative amounts of reticulofibrous bone tissue, prevalence of fibroblastic cells in granulation tissue, and accelerated formation of the regenerate blood microcirculatory channel.
本研究旨在探讨水溶性槲皮素对慢性酒精中毒大鼠下颌骨不完全骨折后病理形态特征的影响。将 14 只体重为 190-240 克的白色雄性 Wistar 大鼠随机分为两组:第 1 组为慢性酒精中毒下颌骨不完全骨折的大鼠;第 2 组动物在诱导损伤后 14 天内每天腹腔注射水溶性槲皮素(山茱萸素),剂量为 10 毫克/千克槲皮素。研究表明,慢性酒精中毒会阻碍下颌骨不完全骨折后骨组织的修复性再生,并伴随着损伤部位网状纤维骨组织和成纤维细胞元素(尤其是成熟的成纤维细胞)相对数量的减少,以及肉芽组织成熟的延迟。在实验条件下,到创伤后第 14 天,服用槲皮素可显著促进再生过程的正常化。这种正常化表现在网状纤维骨组织相对数量的增加、肉芽组织中成纤维细胞的普遍存在以及再生血液微循环通道的加速形成。

SOURCES OF SUPEROXIDE ANION RADICAL IN SMALL INTESTINE TISSUES IN RATS SUBJECTED TO SURGICAL TRAUMA SIMULATED UNDER EXPERIMENTAL MODEL OF POSTTRAUMATIC STRESS DISORDER 创伤后应激障碍实验模型模拟手术创伤大鼠小肠组织中超氧化物阴离子自由基的来源
R.M. Riabushko, V.O. Kostenko
The sources of superoxide anion radical (.О ) in the tissues of the small intestine in rats subjected to surgical trauma simulated under an experimental model of posttraumatic stress disorder (PTSD) were investigated. The study involved 42 white Wistar rats weighing 210-230 g, divided into 6 groups: group 1 comprised intact animals, group 2 included animals with the PTSD induced through single-prolonged stress (SPS), group 3 consisted of rats subjected to a sham surgical operation, group 4 comprised animals undergoing laparotomy, group 5 involved rats undergoing a sham surgical operation following SPS, and group 6 included animals undergoing laparotomy under modeled SPS. The rate of .О generation in the small intestine homogenate was measured spectrophotometrically using the nitroblue tetrazolium test. The .О production by NADPH-dependent (microsomal and NO synthase) electron transport chains (ETC), NADH-dependent (mitochondrial) ETC and leukocyte NADPH oxidase was assessed. The findings obtained have demonstrated that experimental SPS modeling leads to an increase in oxidative stress in the small intestine tissues of rats. This is manifested by an increase in the rate of .О formation with the participation of microsomes, mitochondria and leukocyte NADPH oxidase. On the 7th day after laparotomy under the experimental PTSD model, the .О production in the tissues of the small intestine by different sources (microsomes, mitochondria and leukocyte NADPH oxidase) exceeds their values obtained after a single laparotomy or after performing a sham operation under single long-term stress.
本研究调查了在创伤后应激障碍(PTSD)实验模型下模拟手术创伤的大鼠小肠组织中超氧化物阴离子自由基(.О)的来源。研究涉及42只体重210-230克的白色Wistar大鼠,分为6组:第1组包括完整的动物,第2组包括通过单次持续应激(SPS)诱发创伤后应激障碍的动物,第3组包括接受假手术的大鼠,第4组包括接受开腹手术的动物,第5组包括在SPS后接受假手术的大鼠,第6组包括在模拟SPS下接受开腹手术的动物。小肠匀浆中.О的生成率是用硝基蓝四氮唑试验进行分光光度法测定的。评估了依赖 NADPH(微粒体和 NO 合酶)的电子传递链(ETC)、依赖 NADH(线粒体)的电子传递链(ETC)和白细胞 NADPH 氧化酶产生的.О。研究结果表明,实验性 SPS 模型会导致大鼠小肠组织氧化应激增加。这表现为微粒体、线粒体和白细胞 NADPH 氧化酶参与的.О形成率增加。在创伤后应激障碍实验模型下进行开腹手术后的第 7 天,小肠组织中不同来源(微粒体、线粒体和白细胞 NADPH 氧化酶)的.О 生成量超过了单次开腹手术后或在单次长期应激下进行假手术后获得的数值。

This study addresses the pressing scientific and practical issue in modern dentistry: enhancing dental care effectiveness for patients with chronic rheumatic heart disease. The purpose of this research is to comprehensively assess the condition of tooth-supporting tissues and quantify inflammatory phenomena in periodontal tissues among patients with chronic rheumatic heart disease, as well as to determine the necessary extent of periodontal care based on periodontal indices. Participants and methods. The periodontal tissues of 719 patients with chronic rheumatic heart disease from the Rheumatology Department of Lviv Regional Clinical Hospital, along with 290 clinically healthy individuals in the comparison group, were examined. To evaluate the clinical course of dystrophic-inflammatory periodontal diseases in patients with chronic rheumatic heart disease, we examined 267 individuals in the main group who had generalized periodontitis, categorized as follows: 42 patients with initial stage (I degree), 115 with moderate (II degree), and 110 with severe (III degree) periodontitis. The comparison group comprised 70 patients diagnosed with generalized periodontitis, among them, 21 had initial-stage disease, 29 had moderate-stage disease, and 20 had severe-stage disease. During the analysis, the oral hygiene was assessed by applying hygienic indices by J.C. Green and J.R. Vermillion (OHI-S, 1964) and Fedorov-Volodkina. The Muhlemann and Son index was used to objectively measure gingival papillary bleeding (RVI); the papillary-marginal-alveolar index (PMA) in the Parma modification, in combination with the Schiller-Pysarev test (1989), was employed to evaluate gingival inflammation. The periodontal index (PI) by A.L. Russel (1956) was used to assess the state of periodontal tissues, and pathological changes were recorded using the periodontal screening PSR test. Results were scored, and based on established criteria and scores, the need for treatment and its extent were determined. Results and discussion. According to the results of dental examinations in patients with chronic rheumatic heart disease, a high prevalence of periodontal diseases was found, reaching 92.49%. This was 13.18% higher compared to the prevalence in the control group. Dystrophic-inflammatory conditions with advanced severity levels were predominant, as evidenced by the index indicators. In chronic rheumatic heart disease patients, the average periodontal index was 6.11±0.10, compared to 4.14±0.19 in clinically healthy individuals (p < 0.05). Moreover, a higher lesion of periodontal tissues was observed in younger age groups. As the duration of rheumatic disease increased, the frequency of detecting generalized periodontitis also increased, with this condition being diagnosed in all subjects with a 10-year history of rheumatic disease. Conclusion. The Analysis of the research data on the condition of periodontal tissues, along with objective index assessments, reveals the foll
本研究解决了现代口腔医学亟待解决的科学和实践问题:提高慢性风湿性心脏病患者的口腔护理效果。本研究的目的是全面评估慢性风湿性心脏病患者牙齿支持组织的状况,量化牙周组织的炎症现象,并根据牙周指数确定必要的牙周护理程度。参与者和方法。研究人员检查了利沃夫地区临床医院风湿病科 719 名慢性风湿性心脏病患者的牙周组织,以及对比组中 290 名临床健康者的牙周组织。为了评估慢性风湿性心脏病患者萎缩-炎症性牙周病的临床病程,我们对主要组中 267 名患有全身性牙周炎的患者进行了检查,他们被分为以下几类:初期(Ⅰ度)牙周炎患者 42 人,中度(Ⅱ度)牙周炎患者 115 人,重度(Ⅲ度)牙周炎患者 110 人。对比组由 70 名确诊为全身性牙周炎的患者组成,其中 21 人患有初期牙周炎,29 人患有中度牙周炎,20 人患有重度牙周炎。分析期间,采用 J.C. Green 和 J.R. Vermillion 的卫生指数(OHI-S,1964 年)和 Fedorov-Volodkina 的卫生指数对口腔卫生进行了评估。Muhlemann 和 Son 指数用于客观测量牙龈乳头出血量(RVI);帕尔马改良乳头-边缘-牙槽指数(PMA)结合席勒-皮萨列夫试验(1989 年)用于评估牙龈炎症。采用 A.L. Russel(1956 年)的牙周指数(PI)评估牙周组织状况,并使用牙周筛查 PSR 测试记录病理变化。对结果进行评分,并根据既定标准和评分确定治疗的必要性和程度。结果与讨论根据慢性风湿性心脏病患者的牙科检查结果,发现牙周疾病的患病率很高,达到 92.49%。这比对照组的患病率高出 13.18%。从指数指标来看,严重程度较高的萎缩性炎症占主导地位。慢性风湿性心脏病患者的平均牙周指数为(6.11±0.10),而临床健康人的平均牙周指数为(4.14±0.19)(P<0.05)。此外,年龄较小的人群牙周组织病变程度较高。随着风湿病病程的延长,发现全身性牙周炎的频率也在增加,所有有 10 年风湿病病史的受试者都被诊断出患有全身性牙周炎。结论对牙周组织状况的研究数据以及客观指标评估的分析表明:牙周疾病在慢性风湿性心脏病患者中更为普遍,尤其影响年轻群体。这些疾病的严重程度和进展受潜在疾病的病程影响。这突出表明,存在着导致牙周组织萎缩-炎症过程快速进展的致病条件。这也强调了为慢性风湿性心脏病患者提供专门牙周护理的重要性,护理水平与全身疾病的病程和持续时间直接相关。

This was 13.18% higher compared to the prevalence in the control group. Dystrophic-inflammatory conditions with advanced severity levels were predominant, as evidenced by the index indicators. In chronic rheumatic heart disease patients, the average periodontal index was 6.11±0.10, compared to 4.14±0.19 in clinically healthy individuals (p < 0.05). Moreover, a higher lesion of periodontal tissues was observed in younger age groups. As the duration of rheumatic disease increased, the frequency of detecting generalized periodontitis also increased, with this condition being diagnosed in all subjects with a 10-year history of rheumatic disease. \u0000Conclusion.

FOSTERING KEY VALUES OF ACADEMIC INTEGRITY THROUGH THE EDUCATIONAL PROCESS AT POLTAVA STATE MEDICAL UNIVERSITY 通过波尔塔瓦国立医科大学的教育过程培养学术诚信的主要价值观
T.O. Petrushanko, O.M. Boychenko, T.D. Bublii
Academic integrity serves as the cornerstone of an individual's moral character and their approach to scholarly endeavors. It reflects the moral values that students bring with them to higher education institutions, aiming to enhance and refine them throughout their academic journey and beyond. This article aims to explore the principles underlying the development of academic integrity among teachers, lecturers, and its implementation in the scholarly and educational activities of higher education institutions. Lecturers serve as the primary examples of academic integrity for students. Their commitment to ethical standards, honesty, and openness in discussing ethical issues can influence students and serve as a model for their behavior. At Poltava State Medical University (PSMU), a repository has been established as a platform for showcasing teachers' scientific achievements, publications, research, and other academic accomplishments. Additionally, a bioethics commission oversees adherence to data collection and processing rules, animal experimentation, and the use of new technologies, fostering a conducive atmosphere in line with the ethical standards of academic integrity at PSMU. The patent department at PSMU oversees research ethics, citation rules, and plagiarism prevention, providing educational support, consultation, and assistance in developing intellectual property standards. The university's website offers online resources that encourage teachers to take greater responsibility for their actions and achievements. By making achievements publicly accessible, PSMU promotes adherence to ethical and quality standards among faculty members. Thus, fostering a virtuous academic environment requires a comprehensive approach that includes proper regulatory and legal frameworks, as well as organizational and preventive-educational measures. Establishing an educational environment based on academic integrity for future professionals enables high-quality outcomes, thereby shaping competitive specialists in the global market of social services.
学术诚信是个人道德品质和学术研究方法的基石。它反映了学生在进入高等院校后所带入的道德价值观,目的是在他们的整个学术历程及以后的学习过程中提升和完善这些价值观。本文旨在探讨教师、讲师培养学术诚信的基本原则及其在高等教育机构学术和教育活动中的实施情况。讲师是学生学术诚信的主要榜样。他们对道德标准的承诺、诚实以及在讨论道德问题时的开放态度都会影响学生,并成为学生行为的楷模。波尔塔瓦国立医科大学(PSMU)建立了一个资料库,作为展示教师科研成果、出版物、研究和其他学术成就的平台。此外,生物伦理委员会负责监督数据收集和处理规则的遵守情况、动物实验和新技术的使用,从而在波尔塔瓦国立医科大学营造出符合学术诚信伦理标准的良好氛围。PSMU 的专利部门负责监督研究伦理、引用规则和防止剽窃,提供教育支持、咨询和协助制定知识产权标准。该大学的网站提供在线资源,鼓励教师为自己的行为和成就承担更大的责任。通过公开成果,PSMU 促进教师遵守道德和质量标准。因此,培养良性学术环境需要采取综合方法,包括适当的监管和法律框架,以及组织和预防教育措施。为未来的专业人员建立一个以学术诚信为基础的教育环境,可以取得高质量的成果,从而在全球社会服务市场上培养具有竞争力的专业人才。
