Background. A hypothesis on the main role of factors of psychosocial and psychological distress in the formation of gender differences in mortality in the post-Soviet period is proposed. Aim of the research. To identify the characteristics and main causes of changes in gender trends and indicators of sexual dimorphism in mortality of the population of the Irkutsk region in the post-Soviet period. Methods. Statistical materials were obtained from the databases of the Federal State Statistic Service of the Russian Federation and from the Demographic Yearbooks of Russia. To establish the gender characteristics of irrevocable demographic losses, we analyzed the values of the male excess mortality index. It is defined as the ratio of the mortality rate of men to the corresponding indicator for women. We established the close connection between changes in the male supermortality index and the level of psychological distress of the population. The last index was determined by the suicide rate. Results. During the 31-year period (1987–2017), the highest values of the male mortality index were observed in 1993– 1995 and in 2001–2005. An indicator of the frequency of suicides is proposed and applied as a specific socio-demographic criterion for the influence of the factor of psychological distress on the socio-demographic status of the population. The dependence of the male supermortality index on the level of psychological distress for the period from 1991 to 2017 is estimated. A strong positive relationship between these indicators was identified (r = 0.792; p < 0.0001). Conclusion. Changes in the indicator of male supermortality largely depend on changes in the level of psychological distress. The indicator of sexual dimorphism of mortality (the index of male supermortality) can be used as an important indicator of pronounced changes in psychosocial and psychological distress and, accordingly, the quality of life of a society.
背景。提出了后苏联时期死亡率性别差异形成过程中社会心理和心理困扰因素主要作用的假设。研究的目的。查明后苏联时期伊尔库茨克地区人口性别趋势变化的特点和主要原因,以及性别二态性死亡率指标。方法。统计资料是从俄罗斯联邦国家统计局的数据库和《俄罗斯人口年鉴》获得的。为了确定不可挽回人口损失的性别特征,我们分析了男性超额死亡率指数的值。它被定义为男性死亡率与女性相应指标的比率。我们建立了男性超死亡率指数的变化与人口心理困扰水平之间的密切联系。最后一个指标是由自杀率决定的。结果。在31年期间(1987-2017年),1993 - 1995年和2001-2005年男性死亡率指数最高。提出了自杀频率指标,并将其作为衡量心理困扰因素对人口社会人口状况影响的具体社会人口标准。估计了1991 - 2017年男性超死亡率指数对心理困扰水平的依赖关系。这些指标之间存在很强的正相关关系(r = 0.792;P < 0.0001)。结论。男性超死亡率指标的变化在很大程度上取决于心理困扰程度的变化。性别二态性死亡率指数(男性超死亡率指数)可以作为社会心理和心理痛苦显著变化的重要指标,从而反映一个社会的生活质量。

Background. An infant brain damage is an extremely urgent problem, this pathology is difficult to prevent, and subsequently it manifests itself with a variety of neurological consequences. Various mechanisms are involved in neurodamage; cytokines, as well as genes that control their activity, are under a great concern today. However, there is little data about their role as predictors of the brain damage among children after hypoxia. Aim of the research. To identify the frequency of cytokine gene polymorphism: interleukin (IL)-1β(C-511T), IL-1β(C3953T), IL-4(C589T), IL-6(C174G), IL-10(C819T), IL-10(G1082A) among newborns with hypoxic events. Materials and methods. The study involved 128 full-term newborn patients with hypoxic events: the first group (n = 48) included newborns who experienced chronic intrauterine hypoxia (CVH), the second group (n = 80) included newborns born in asphyxiation. Control group (52) included babies born without asphyxia and not suffering from CVH. A retrospective analysis of case-records was carried out. The material for molecular genetic analysis was DNA samples isolated from umbilical cord blood leukocytes using DNA Express Blood reagents (Scientific and Production Company LITECH, Moscow). Results. Compared to the control group (p = 0.03) children born in asphyxia had their T allele IL-1β (C-511T) prevailed. The group of newborn who had CVH had their TT genotype (p = 0.04) and the T IL-1β allele (C-511T) (p = 0.01) prevailed compared to the control group. In the same study group while studying the polymorphism of the IL-1β gene, the T allele (p = 0.03) at the point C3953T prevailed, in contrast to the control group. Conclusion. Due to the fact that cytokines are part of a reaction cascade leading to the secondary brain damage, under the action of hypoxia, it was found that among newborns undergoing asphyxia and chronic intrauterine hypoxia the increased frequencies of carriage of IL-1β-511TT and IL-1β-3953TT genotypes, and IL-1β-511T and IL-1β-3953T alleles increase the risk of neurodamage.
背景。婴儿脑损伤是一个极其紧迫的问题,这种病理是难以预防的,随后它表现出各种神经系统的后果。神经损伤涉及多种机制;细胞因子,以及控制其活性的基因,在今天受到了极大的关注。然而,关于它们在儿童缺氧后脑损伤预测中的作用的数据很少。研究的目的。探讨新生儿缺氧事件中白细胞介素(IL)-1β(C-511T)、IL-1β(C3953T)、IL-4(C589T)、IL-6(C174G)、IL-10(C819T)、IL-10(G1082A)基因多态性的频率。材料和方法。该研究涉及128例有缺氧事件的足月新生儿:第一组(n = 48)包括经历慢性宫内缺氧(CVH)的新生儿,第二组(n = 80)包括窒息出生的新生儿。对照组(52例)包括出生时无窒息、无CVH的婴儿。对病例记录进行回顾性分析。分子遗传学分析的材料是从脐带血白细胞中分离的DNA样本,使用DNA Express blood试剂(science and Production Company LITECH, Moscow)。结果。与对照组相比(p = 0.03),出生时窒息患儿的T等位基因IL-1β (C-511T)占优势。新生儿CVH组TT基因型(p = 0.04)和T IL-1β等位基因(C-511T)比对照组占优势(p = 0.01)。在同一研究组中,在研究IL-1β基因多态性时,与对照组相比,C3953T位点的T等位基因占主导地位(p = 0.03)。结论。由于细胞因子是导致继发性脑损伤的级联反应的一部分,在缺氧的作用下,我们发现在窒息和慢性宫内缺氧的新生儿中,IL-1β-511TT和IL-1β-3953TT基因型以及IL-1β-511T和IL-1β-3953T等位基因携带频率的增加增加了神经损伤的风险。

Background. Coronary heart disease is the leading cause of death in the Russian Federation, causing social and economic damage to the state. Previously published studies showed the association of rs1800470 polymorphism of the gene of the transforming growth factor-β1 (TGF-β1) with the risk of developing coronary artery disease due to more severe atherosclerotic lesions of the coronary arteries. Aim of the research. To study the association of single-nucleotide polymorphism rs1800470 of the TGF-β1 gene with the rate of progression of atherosclerotic coronary artery lesion. Material and methods. The study included 89 men with myocardial infarction, a Caucasian race under the age of 65 years (51 ± 7.9). Genomic DNA was isolated from venous blood by the phenol-chloroform method. The rs1800470 polymorphism of the TGF-β1 gene was tested using real-time polymerase chain reaction (PCR) (TaqMan probes, AB 7900HT). Assessment of the severity of coronary lesion was carried out initially according to the standard polyprojection coronary angiography protocol with the Gensini score calculated, as well as in dynamics after 40.7 ± 29.7 months (from 5 to 103 months). Results. Carrier of the rs1800470 allele A of the TGF-β1 gene is an independent risk factor for coronary heart disease and is associated with a more aggressive course of coronary atherosclerosis in men: a 20 % worsening of the Gensini score was observed after 7 months (p = 0.013), and by 30 % after 5 months (p = 0.003) from the initial coronary angiography. In addition, the homozygous genotype AA rs1800470 of the TGF-β1 gene is associated with the development of late stent restenoses in this group of patients after 12 months of observation (p = 0.002). Conclusion. Identification of carriers of the rs1800470 allele A of the TGF-β1 gene can help identify patients at risk for more rapid progression of coronary artery atherosclerosis in order to conduct angiographic control in the early period – 6 months from the initial percutaneous coronary intervention.
背景。冠心病是俄罗斯联邦的主要死亡原因,对国家造成社会和经济损害。先前发表的研究表明,转化生长因子-β1 (TGF-β1)基因rs1800470多态性与冠状动脉粥样硬化病变加重导致冠状动脉疾病的发生风险相关。研究的目的。研究TGF-β1基因单核苷酸多态性rs1800470与动脉粥样硬化性冠状动脉病变进展速度的关系。材料和方法。该研究纳入89例65岁(51±7.9)岁以下的心肌梗死男性白种人。采用苯酚-氯仿法从静脉血中分离基因组DNA。采用实时聚合酶链反应(PCR) (TaqMan探针,AB 7900HT)检测TGF-β1基因rs1800470多态性。最初根据标准多投影冠状动脉造影方案进行冠状动脉病变严重程度评估,计算Gensini评分,并在40.7±29.7个月(从5到103个月)后进行动态评估。结果。TGF-β1基因rs1800470等位基因A的携带者是冠心病的独立危险因素,与男性冠状动脉粥样硬化的侵袭性病程相关:7个月后观察到Gensini评分恶化20% (p = 0.013), 5个月后恶化30% (p = 0.003)从最初的冠状动脉造影。另外,TGF-β1基因AA rs1800470纯合子基因型与本组患者观察12个月后发生晚期支架再狭窄相关(p = 0.002)。结论。识别TGF-β1基因rs1800470等位基因A的携带者,有助于识别冠状动脉粥样硬化进展更快的高危患者,以便在早期-经皮冠状动脉介入治疗后6个月进行血管造影控制。

Perioperative bleeding occupies a leading place among all surgical complications and, despite the rapid development of surgery, remains relevant to this day. In addition to an increase in mortality, bleeding can cause the development of other postoperative complications, which lead to disability of patients and to a decrease in the quality of life in all age groups. Most perioperative bleeding are caused by technical errors. This article reviews the problem of perioperative bleeding from the point of view of impaired coagulation capabilities of the body. The main etiopathogenetic features of hemostasis during the development of this complication are considered. The analysis of postoperative complications, which were directly or indirectly caused by bleeding during or after surgery, is presented. The prevalence of these complications in various areas of surgery has been demonstrated. More detailed study of the hemostasis system and the identification of predictors of hemostasis difficulties before the surgery may cause an improvement in the results of surgical treatment and reduce the number of postoperative complications and the duration of hospital stay. Accordingly, this will lead to a decrease in the cost of treatment and an increase in patient satisfaction with the medical care. In connection with the above, there is a great interest among surgeons and anesthesiologists in preventing the development of perioperative bleeding.
围手术期出血在所有外科并发症中占主导地位,尽管外科手术发展迅速,但至今仍具有相关性。除了死亡率增加外,出血还可引起其他术后并发症,导致患者残疾,并降低所有年龄组的生活质量。大多数围手术期出血是由技术错误引起的。本文从机体凝血功能受损的角度综述围手术期出血问题。在此并发症的发展过程中,止血的主要发病特征被考虑。本文对术中或术后出血直接或间接引起的术后并发症进行了分析。这些并发症在不同手术领域的流行已经得到证实。术前对止血系统进行更详细的研究,确定止血困难的预测因素,可能会改善手术治疗效果,减少术后并发症的发生,缩短住院时间。因此,这将降低治疗费用,提高病人对医疗服务的满意度。有鉴于此,外科医生和麻醉师对预防围手术期出血的发展非常感兴趣。

Parathyroidectomy is the leading treatment for drug-refractory secondary and tertiary hyperparathyroidism in patients with chronic kidney disease. Difficulties in performing this surgery are mainly associated with the anatomical features of the parathyroid glands, in particular with the variability of their number and topographic anatomy. Ectopic parathyroid glands are one of the most common causes of persistence or recurrence of secondary hyperparathyroidism after surgery. One of the common variants of ectopia is the localization of the parathyroid gland in the anterior-superior mediastinum. The article discusses the features of surgical treatment of secondary hyperparathyroidism in patients with end-stage chronic kidney disease with this ectopia. A new method of treating hyperparathyroidism in patients with an atypical location of the parathyroid gland in the anterior-superior mediastinum is presented. This method is characterized by low invasiveness of access, ease of implementation without using special equipment and instruments. The proposed method was used in the treatment of a patient with secondary hyperparathyroidism due to chronic renal failure as a result of chronic glomerulonephritis. The duration of hemodialysis at the time of the surgery was more than 17 years. In the presented clinical case, ectopia of one of the pathologically altered parathyroid glands in the anterior-superior mediastinum was found at the preoperative stage. As a method of surgical treatment, we carried out total parathyroidectomy with autotransplantation of a fragment of parathyroid tissue into the brachioradialis muscle. Thanks to this method, it was possible to remove the atypically located parathyroid gland from the cervicotomy access and to discharge the patient within the standard terms for a given volume of surgery.
甲状旁腺切除术是治疗慢性肾病患者难治性继发性和三期甲状旁腺功能亢进的主要方法。实施该手术的困难主要与甲状旁腺的解剖特征有关,特别是其数量和地形解剖的可变性。异位甲状旁腺是术后继发性甲状旁腺功能亢进持续或复发的最常见原因之一。异位的常见变种之一是甲状旁腺的定位在前上纵隔。本文讨论终末期慢性肾病伴此异位的继发性甲状旁腺功能亢进患者的手术治疗特点。本文提出一种治疗甲状旁腺位于前上纵隔非典型位置的甲状旁腺功能亢进的新方法。该方法的特点是侵入性低,无需特殊设备和仪器即可实现。所提出的方法被用于治疗继发性甲状旁腺功能亢进患者由于慢性肾小球肾炎引起的慢性肾功能衰竭。手术时血液透析持续时间超过17年。在本病例中,术前发现前上纵隔病变的甲状旁腺之一异位。作为一种外科治疗方法,我们进行了全甲状旁腺切除术,并将甲状旁腺组织碎片自体移植到肱桡肌中。由于这种方法,有可能从颈部切开术通道中去除非典型位置的甲状旁腺,并在给定手术量的标准期限内出院。

Background. Sporadic multiple gland disease in primary hyperparathyroidism occurs in 7 to 33 % of cases. The absence of specific risk factors, low sensitivity of imaging methods, and low efficiency of bilateral neck exploration and intraoperative monitoring of parathyroid hormone indicate the complexity of the diagnosis and treatment of this disease’s form. Aim of the research. To analyze the results of surgical treatment of multiple lesions of the parathyroid gland in primary and secondary hyperparathyroidism. Methods. There was retrospective study, which included 100 observations of surgical treatment for primary and secondary hyperparathyroidism in the thoracic department of Irkutsk Regional Clinical Hospital from May 2018 to September 2019. The main point was to identify the frequency of surgical treatment outcomes in patients with multiple parathyroid lesions. As part of the study, potential predictors of multiple gland disease in primary hyperparathyroidism were analyzed. Results. Multiple gland disease in primary hyperparathyroidism occurs in 29 % of cases and causes persistence of the disease (p ≤ 0.01). Signs of multiple gland disease in primary hyperparathyroidism include the level of ionized calcium, parathyroid hormone (p ≤ 0.05), creatinine level and glomerular filtration rate (p ≤ 0.01). A negative result of intraoperative monitoring correlates with persistence of primary hyperparathyroidism in multiple lesions (χ2, p ≤ 0.05). Selective parathyroidectomy is associated with persistence of hyperparathyroidism in multiple lesions (χ2, p ≤ 0.05), while total parathyroidectomy is associated with remission of the disease (χ2, p ≤ 0.05). We did not find a statistically significant relationship between the results of surgical treatment for morphology of the parathyroid glands (χ2, p > 0.1). Conclusion. Multiple gland disease is the main cause of persistence of primary hyperparathyroidism. This form of the disease corresponds to lower levels of calcium, parathyroid hormone, and kidney function. Persistence factors have been established: removal of less than four parathyroid glands and a negative result of intraoperative monitoring of parathyroid hormone. Bilateral neck exploration does not reduce the incidence of disease persistence.
背景。原发性甲状旁腺功能亢进症的散发性多腺体疾病发生率为7%至33%。由于缺乏特定的危险因素,影像学方法的敏感性低,双侧颈部探查和术中甲状旁腺激素监测的效率低,表明本病的诊断和治疗的复杂性。研究的目的。目的分析原发性和继发性甲状旁腺功能亢进多发病变的手术治疗效果。方法。回顾性研究包括2018年5月至2019年9月伊尔库茨克地区临床医院胸外科对原发性和继发性甲状旁腺功能亢进手术治疗的100例观察。主要目的是确定多发甲状旁腺病变患者的手术治疗频率。作为研究的一部分,我们分析了原发性甲状旁腺功能亢进患者多腺体疾病的潜在预测因素。结果。原发性甲状旁腺功能亢进症的多腺体病变发生率为29%,并导致疾病持续(p≤0.01)。原发性甲状旁腺功能亢进症多腺体病变的征象包括离子钙水平、甲状旁腺激素水平(p≤0.05)、肌酐水平和肾小球滤过率(p≤0.01)。术中监测阴性与多发病变中原发性甲状旁腺功能亢进持续存在相关(χ2, p≤0.05)。选择性甲状旁腺切除术与多个病变中甲状旁腺功能亢进的持续存在相关(χ2, p≤0.05),而完全甲状旁腺切除术与疾病缓解相关(χ2, p≤0.05)。我们没有发现手术治疗对甲状旁腺形态的影响有统计学意义(χ2, p > 0.1)。结论。多发性腺体疾病是原发性甲状旁腺功能亢进持续存在的主要原因。这种形式的疾病对应于低水平的钙,甲状旁腺激素和肾功能。持续因素已确定:切除甲状旁腺少于4个,术中监测甲状旁腺激素阴性。双侧颈部探查不能降低疾病的发生率。

Background. The most common chronic cerebrovascular pathology is dyscirculatory encephalopathy, in which a decrease in blood supply due to damage to brachiocephalic vessels leads to damage to brain substances and analyzers, including visual, with the possible development of severe damage in the form of ischemic optic neuropathy. Many studies have been devoted to the relationship between atherosclerotic damage to the neck vessels and ischemic damage to the visual organ, but little attention has been paid to the study of the functional activity of the altered visual analyzer in patients with dyscirculatory encephalopathy, and the results are scattered. Aim. To conduct a comparative analysis of changes in neurophysiological parameters of the brain and visual analyzer in patients with dyscirculatory encephalopathy and patients with a combination of dyscirculatory encephalopathy and ischemic optic neuropathy. Materials and methods. 34 patients with the 2nd stage of dyscirculatory encephalopathy were examined and divided into two groups based on the presence/absence of ischemic optic neuropathy of various prescription periods. All patients underwent ultrasound scanning of neck vessels, visual fields determination, electroretinography, visual evoked potentials, and electroencephalogram. Results. The results revealed changes in a number of indicators in the group of patients with a combination of two diseases: more pronounced atherosclerotic lesion of brachiocephalic vessels, a decrease in the amplitude and the alpharhythm prevalence index, a decrease in oscillatory potentials, a change in latency and amplitudes the visual analyzer according, lengthening of time indicators with a simultaneous decrease in amplitudes and depression of retinal sensitivity. Conclusion. Patients with dyscirculatory encephalopathy complicated by ischemic optic neuropathy have a combined lesion of the brain and visual analyzer, which determines the severity of the detected changes and requires a comprehensive multidisciplinary approach to the treatment of these patients.
背景。最常见的慢性脑血管病理是循环障碍性脑病,其中由于头臂血管损伤导致血液供应减少,导致脑物质和包括视觉在内的分析仪受损,并可能发展为缺血性视神经病变的严重损害。关于颈部血管粥样硬化损伤与视觉器官缺血性损伤关系的研究较多,但对改变后的视觉分析仪在循环障碍性脑病患者中的功能活性的研究较少,研究结果也比较分散。的目标。对比分析循环障碍性脑病患者与循环障碍性脑病合并缺血性视神经病变患者脑及视觉分析仪神经生理参数的变化。材料和方法。对34例第二期循环障碍脑病患者进行检查,根据不同处方期有无缺血性视神经病变分为两组。所有患者均行颈部血管超声扫描、视野测定、视网膜电图、视觉诱发电位和脑电图检查。结果。结果显示两种疾病合并组患者的多项指标发生变化:头臂血管动脉粥样硬化病变更明显,振幅和节律流行指数下降,振荡电位下降,视觉分析仪显示潜伏期和振幅变化,时间指标延长,同时振幅下降,视网膜敏感性下降。结论。循环障碍性脑病合并缺血性视神经病变患者具有脑和视觉分析仪的联合病变,这决定了检测到的变化的严重程度,需要综合多学科方法来治疗这些患者。

A significant contribution to the morbidity and mortality of children is due to hereditary pathology, which is manifested by high mortality. Aim of the research. To study the frequency of occurrence, structure and clinical and laboratory markers of hereditary metabolic diseases in children of the first half of the year with suspicion of this pathology. Materials and methods. A retrospective analysis of case histories (form No. 003/y) and a face-to-face examination of patients directed to blood tests by tandem mass spectrometry, from Surgery Unit No. 2 for Newborns and Premature Babies and from the Unit of Pathology of Newborns, (Ivano-Matryoninskaya City Children’s Clinical Hospital, Irkutsk). Results. In 2019, 21 children with suspected hereditary metabolic diseases were examined using the tandem mass spectrometry method in the above mentioned departments. All of them had at least one of the main clinical criteria for hereditary metabolic diseases: 67 % had hepatomegaly in combination with an increase in the level of liver enzymes, 43 % had a hereditary history and metabolic acidosis, 33 % showed a sudden deterioration after a period of normal development, 24 % had hypoglycemia, and 14 % had an abnormal urine or body odor, in 4.7 % of cases there was an increase in ketone bodies in the blood and (or) urine. All children identified from 3 to 7 additional criteria, which are indications for examination on the hereditary metabolic diseases. The results of the study revealed 5 children with hereditary metabolic diseases namely amino acid metabolism. 90 % of them had a burdened hereditary history, 100 % had a concomitant pathology – hepatitis and cholestatic lesions of the liver, anemia, an open oval window and others. Conclusion. Despite the obvious economic and medical significance of preclinical identification of patients with hereditary metabolic diseases, the screening problem contains many open questions that need to be addressed at all levels of the organization.
造成儿童发病率和死亡率的一个重要原因是遗传病理,这表现为高死亡率。研究的目的。研究上半年疑似遗传性代谢性疾病患儿的发病频率、结构及临床、实验室标志物。材料和方法。回顾性分析病历(003/y号表格),并对新生儿和早产儿第二外科病房和新生儿病理病房(伊尔库茨克伊万诺- matryoninskaya市儿童临床医院)的患者进行面对面检查,通过串联质谱法进行血液检查。结果。2019年对上述科室21例疑似遗传性代谢性疾病患儿进行串联质谱检测。他们所有人都至少有一个主要的遗传性代谢疾病临床标准:67%有肝肿大结合肝酶水平的增加,43%有历史遗传和代谢性酸中毒,33%显示突然恶化经过一段时间的正常发展,低血糖,24%和14%有异常尿液或体味,在4.7%的病例有增加血液中酮体和(或)尿液。所有儿童确定了3至7项额外标准,这些标准是遗传代谢疾病检查的指征。研究结果显示5名儿童患有遗传性代谢性疾病,即氨基酸代谢。其中90%的人有沉重的遗传史,100%的人有伴随的病理-肝炎和肝脏的胆汁淤积性病变,贫血,一个开放的椭圆窗等。结论。尽管对遗传性代谢性疾病患者的临床前鉴定具有明显的经济和医学意义,但筛查问题包含许多悬而未决的问题,需要在组织的各个层面加以解决。

Background. Previously, we have shown that the polyhexamethylene guanidine hydrochloride hydrogel exhibits a pronounced wound healing. At the same time, no studies of the toxic effect of the hydrogel on animals have been conducted. Aim of the research. In the framework of this work, the acute toxicity of the hydrogel polyhexamethylene guanidine hydrochloride was studied in laboratory animals with intragastric administration. Materials and methods. The polyhexamethylene guanidine hydrochloride hydrogel was obtained by crosslinking the amino end groups with formaldehyde. An acute toxicity study was carried out (P 1.2.3156-13, GOST 32644-2014 and the Guidelines for conducting preclinical studies of drugs) in an experiment on outbred mice with a single addition of the test substance in different doses (1000, 3000, 5000, 8000 mg/kg) with fixing indicators (appearance, behavior, condition of the body hair coat, water and food consumption, excretion, body weight and its growth) during 14 days. After the animals were withdrawn from the experiment, autopsy, macroscopic evaluation and weighing of the internal organs were performed. The results showed that with the introduction of the test substance into the animal organism, death during the observation period (14 days) did not occur. It was not possible to determine the semi-lethal dose for the test compound. Conclusion. The conducted studies allow us to conclude that this substance is practically non-toxic and can be classified as hazard class V. Further research will be directed to the formation of hydrogel compositions with medicinal substances.
背景。以前,我们已经表明,聚六亚甲基胍盐酸盐水凝胶表现出明显的伤口愈合。同时,还没有对水凝胶对动物的毒性作用进行过研究。研究的目的。在本研究的框架内,研究了水凝胶聚六亚甲基胍盐酸盐在实验动物中灌胃的急性毒性。材料和方法。将氨基端与甲醛交联,得到了聚六亚甲基胍盐酸盐水凝胶。采用外交种小鼠进行急性毒性研究(P 1.2.3156-13, GOST 32644-2014和药物临床前研究指南),分别以不同剂量(1000、3000、5000、8000mg /kg)单次添加试验物质,固定14天的试验指标(外观、行为、体毛状况、饮水和食物消耗、排泄、体重及其生长)。动物退出实验后,进行解剖、宏观评价和内脏称重。结果表明,将试验物质引入动物机体后,观察期内(14 d)未发生动物死亡。不可能确定试验化合物的半致死剂量。结论。所进行的研究使我们得出结论,该物质实际上是无毒的,可以被归类为危害类v。进一步的研究将针对与药用物质形成水凝胶组合物。

Background. Spontaneous miscarriage is the most common complication of pregnancy. Obesity increases the risk of adverse pregnancy outcomes. Aim of the study. To assess the cytokine profile as a marker of spontaneous miscarriage in women with metabolic disorders in the past medical history. Materials and methods. A prospective study of 170 adolescent girls with metabolic disorders was conducted between 2000 and 2013. Assessment of menstrual and reproductive function was carried out in 86, pregnancy outcomes – in 72 women. The average age of women in reproductive age was 21.95 ± 0.2 years, BMI – 24.7 ± 3.9 kg/m2. Results. In women with early pregnancy losses and metabolic disorders in past medical history, the predictor of an early pregnancy loss is an increase in the ratio of pro- and anti-inflammatory cytokines TNF-a/IL-10 in serum at 7–8 weeks of gestation (OR = 2.29). It was determined a significant correlation between the levels of pro- and anti-inflammatory cytokines of the same name in serum and chorion (IL-10 (p = 0.000) and TNF-α/IL-10 (p = 0.001), which indicates similar changes in chorion. The activity of NF-kB in chorion was 5.75 ± 0.51 pg/ml. Conclusions. The findings suggest that the cytokine balance of pro- and anti-inflammatory cytokines in women with metabolic disorders in past medical history is an important component in the development of early pregnancy losses.
背景。自然流产是妊娠最常见的并发症。肥胖会增加不良妊娠结局的风险。研究的目的。评估细胞因子谱作为既往病史中有代谢紊乱的妇女自发性流产的标志物。材料和方法。在2000年至2013年期间,对170名患有代谢紊乱的青春期女孩进行了一项前瞻性研究。对72名妇女的86例妊娠结局进行了月经和生殖功能评估。育龄妇女平均年龄21.95±0.2岁,BMI - 24.7±3.9 kg/m2。结果。在既往病史中有早孕丢失和代谢紊乱的妇女中,早孕丢失的预测因子是妊娠7-8周时血清中促炎性和抗炎性细胞因子TNF-a/IL-10比值的增加(OR = 2.29)。血清和绒毛膜中同名促炎因子和抗炎因子(IL-10 (p = 0.000)和TNF-α/IL-10 (p = 0.001)水平之间存在显著相关性,表明绒毛膜的变化相似。绒毛膜中NF-kB活性为5.75±0.51 pg/ml。结论。研究结果表明,既往有代谢障碍的妇女的促炎性和抗炎性细胞因子平衡是早期妊娠丢失的重要组成部分。
