Th is review provides data on genetic melanoma markers over the past few years. p16 cyclin-dependent kinase inhibitor gene (CDKN2A), which was identifi ed as the fi rst gene for the development of skin melanoma more than 20 years ago, is still the gene of the main high-risk. Th ere was cyclin-dependent kinase 4 (CDK4), responsible for cell proliferation presented. Recent advance in molecular genetics has revealed new genes involved in melanoma pathogenesis: breast cancer gene 1 (BRCA1) associated protein 1 (BAP1), CXCL1 genes, telomerase catalytic subunit (TERT), telomere 1 protection (POT1), ACD and TERF2IP. Along with such genes as melanocortin 1 receptor (MC1R) and transcription factor, mutation of which is accompanied by microphthalmos (MITF), are of moderate risk. Th e review also covers a number of other low-penetrant genes of prognostic value.
Keywords: skin melanoma, genetic markers, CDKN2A, CDK4, MITF, TERT, MC1R.

Petrova MM, Shnayder NA, Pronina EA, Bobrova OP. Diagnosis of neuropathic pain: scales and questionnaires. Siberian Medical Review.2020;(3):61-69. DOI 10.20333/2500136-2020-3-61-69
Diagnosis of neuropathic pain can be diffi cult for primary care professionals. Chronic pain is oft en underestimated and is not treatable. Several scales and questionnaires have been developed assessing pain presence, pain intensity, pain allocation, as well as psychological and functional eff ects of pain, including assessment of symptoms in a patient, and some being supplemented by simple methods of clinical examinations to detect signs of nervous system damage. Screening tools are not ideal, and it would be incorrect to think that they can replace clinical assessment. However, the greatest benefi t will be for screening purposes to help a specialist identify neuropathic pain or pain that has predominantly neuropathic component.
Keywords: neuropathic pain, diagnosis, screening, pain assessment, questionnaires, scales.
miR-204-5p level modulation that induces formation of premetastatic niche in B16 melanoma in vivo model
Lavrentev SN, Aksenenko MB, Averchuk AS, Zinchenko IS. miR-204-5p level modulation that induces formation of premetastatic niche in B16 melanoma in vivo model. Siberian Medical Review.2020;(3):70-77. DOI 10.20333/2500136-2020-3-70-77
Th e aim of the research. Determination of microRNA profi le in metastasis target organs aft er experimental increase of their level by synthetic analogue miR-204-5p in vivo. Material and methods.Th e study was performed in laboratory mice of C57Bl6 line who were implanted with B16 melanoma culture cells to form subcutaneous solid tumor. Animals that were inoculated with melanoma were divided into III groups: check (n = 3); negative check (n = 5); experimental (n = 6), animals of this group got synthetic analogue (simulator) of the studied miR-204-5p microRNA, at a dosage of 1.2 mg / kg in the form of a solution. Results. Th e study of miR-204-5p expression in tissues of kidneys, lungs, and liver of experimental animals showed an increase in this miRNA expression ninefold compared with the check one in kidney tissues. Next, microRNA expression profi le of this tissue was determined. Microchipping results showed that aft er miR-204-5p simulator introduction, the level of 12 miRNAs changes, while 9 miRNAs had a reduced expression level of more than 2 times. These miRNAs are involved in regulation of component genes of 47 intracellular signal transmission mechanisms. Signal transmission mechanisms regulated by miRNAs with the highest change level included signaling pathways of mitogen-activated protein kinases (MAPK), proteoglycans in case of cancer, renal cell kidney carcinoma, cell adhesion, lysine degradation, regulation of calcium reabsorption and synthesis of various types of hormones. Conclusion. When introducing antisense nucleotides, their increased concentration, and hence the expected eff ects, are observed in kidney tissues. Analysis of signaling cascades regulated by miRNAs with the highest change level showed transformation of signaling mechanisms functionally associated with carcinogenesis, including kidney cancer. Similar result may indicate possible formation of premetastatic niches in kidney tissue of experimental animals

Th e aim of the research is to assess the eff ect of inhalation anesthetics, such as desfl urane and sevofl urane, used during general anesthesia, on jugular venous oximetry parameters change. Material and methods. Th e analysis of indicators of central hemodynamics, blood loss and jugular venous oximetry at various stages of clipping in patients with ruptured intracranial arteries aneurysms in 2 groups, 30 patients in total: 1 group of patients, where desfl urane was used during general anesthesia and 2 group of patients – general anesthesia with sevofl urane. Results. Patients from both groups were compared according to severity of subarachnoid hemorrhage and its intensity. When conducting general anesthesia with both desfl urane and sevofl urane, common hemodynamic changes were observed that were not statistically diff erent; the volume of intraoperative blood loss and hemoglobin level in patients of these groups also did not have statistically signifi cant diff erence. At the same time, in patients of group 1 at II-V stages, jugular oximetry indexes were statistically signifi cantly higher than in patients of group 2. Conclusion. Th e use of desfl urane as general anesthesia during such surgical intervention as clipping of ruptured intracranial aneurysms, compared with sevofl urane, is accompanied by higher jugular oximetry indexes, which corresponds to greater decrease in brain neurons metabolic activity. A more pronounced decrease in brain neurons metabolic activity has favorable protective eff ect and should be taken into account when choosing inhalant anesthetic

The aim of the research is to study the state of systemic microcirculation in patients with diabetes mellitus depending on the development of diabetic foot syndrome. Material and methods. The state of systemic microcirculation was studied in 60 patients. Group I consists of 30 patients without diabetic foot, group II consists of 30 patients with diabetic foot. Comparison group includes 30 healthy people. Results. Microcirculation index (M) in patients of group II is lower than in the check group and in group I by 1.4 times (р<0,05; p1 <0,05). Th e average perfusion fl uctuation value (σ) relative to blood fl ow arithmetic mean M in the group of patients with diabetic foot is lower than in the comparison group by 1.6 times (p = 0.002). Th e level of maximumfl uctuation amplitude in endothelial range (Aэ) in patients of groups I and II is lower than in the check group by 1.4 times (p = 0.03; p1 = 0.03). Th e value of maximum fl uctuationamplitude in neurogenic range (Aн) incase of diabetic foot is 1.4 times lower than in the check group (p = 0.010). Maximum amplitude index in myogenic range (Aм) in patients of group II is lower than in the comparison group by 1.6 times (p = 0.002). The level of maximum fl uctuation amplitude of blood fl ow in the respiratory range (Ад) in group II is 1.6 times (p = 0.002)lower than in the check group. Maximum amplitude value in pulse range (Ac) in the group of patients with diabetic foot is 1.2 times (p = 0.002)lower than in the check one. Conclusion. Microcirculatory disorders at systemic level, manifested by the decrease in average perfusion, intensity of active and passive mechanisms of microvasculature regulation in diabetic foot syndrome, indicate more pronounced systemic changes at the level of microcirculatory vessels relative to patients with uncomplicated diabetes, which requires screening and identifi cation of increased risk of this complications group

Th e aim of the research is to study the proportion of prenatal infections in the structure of early neonatal mortality in Omsk region for the period of 2010-2018. Material and methods. Retrospective analysis of the dynamics and structure of early neonatal mortality reasons in Omsk region for the period of 2010-2018 was carried out. “Information on medical care for pregnant women, parturient women and puerperants” (Form No. 32) and protocols of the pathoanatomical study of newborns who died in the early neonatal period were used for the analysis. Results. From 2010 to 2018, 597 cases of early neonatal mortality in total were recorded in Omsk Region, 171 of which were full-term, 211 were premature in pregnancy and 28-37 weeks prematurely, 215 were premature with VLBW. Th e main reasons for early neonatal mortality of mature fetuses in Omsk region are: congenital malformations (18.1 %) and intrauterine asphyxia (15.7 %); in premature fetuses the leading reasons are: respiratory disorders in the newborn (fetal distress) – 24.6 % in the group of preterm births at 28-37 weeks and 43.7 % at very early preterm delivery. Conclusion. Prenatal infections are the main cause of RNS in full-term fetuses, accounting for 24.3 % of the total number of deaths in the early neonatal period (congenital pneumonia P23 – 10 %, infectious diseases specifi c for the perinatal period P35-P39 – 14.3 %). Infectious pathology is oft en combined with such diagnoses as intrauterine hypoxia, asphyxia in childbirth, cerebral ischemia, congenital malformations of the fetus, intracranial non-traumatic hemorrhages in the fetus and newborn, which are among the main diagnosis. According to the pathological fi ndings in full-term infants, infectious diseases specific for the perinatal period (P35-P39) were associated in 21.4 % of cases, in children with ENMT – in 24.2 %, in premature babies of 28-37 weeks – 23.1 %.

Th e aim of the research is to analyze the infl uence of mortality rate changes in Krasnoyarsk Territory to the dynamics of life expectancy indicator for the period from 2012 to 2016. Material and methods. Th e data of Krasnoyarsk Territory statistical yearbooks issued by Offi ce of Federal State Statistics Service for Krasnoyarsk Territory, Republic of Khakassia and Republic of Tuva, as well as primary mortality databases for urban districts and municipal districts of Krasnoyarsk Territory for the period from 2012 to 2016, were used. Th e dynamics of life expectancy indicator, total mortality, mortality and average age of the dead according to the main death cause groups is analyzed. Analysis of mortality dynamics influence in certain age groups and infl uence of mortality changes from various causes on the dynamics of life expectancy was calculated using E. M. Andreeva method. Results. Mortality of Krasnoyarsk Territory population for the period from 2012 to 2016 decreased by 3.9 %, the average age of the dead increased by 2.2 %, and life expectancy increased by 2.3 %. During the analyzed period, the greatest increase was determined in mortality due to blood diseases, blood-forming organs, and certain disorders involving immune mechanism, diseases of nervous system, and diseases of skin and subcutaneous tissue. Mortality index from mental and behavioral disorders, certain conditions that occur in perinatal period and old age and inaccurately identifi ed and unknown causes of death decreased to a greater extent. The largest negative contribution to life expectancy dynamics of Krasnoyarsk Territory population is associated with mortality change due to neoplasms in the age group of 75-79 years, some infectious and parasitic diseases in the age group of 35-39 years, diseases of digestive system in the age group of 40-44 years and neoplasms in the age groups of 80-84 and 85-89 years. Conclusion. Th e analysis made it possible to identify the components of mortality change that contribute more to the increase in life expectancy of Krasnoyarsk Territory population, as well as components that reduce its growth rate.
