MicroRNAs (miRNA, miR) - regulate gene expression, take part in the regulation of cell life, proliferation and apoptosis. There are not enough publications on the study of microRNA in the plasma of patients with choroidal melanoma (CM) and the presented data are contradictory. An increase in the level of microRNA-146a in blood plasma was noted in patients with cancer of the lung, esophagus and breast. In the present study, we used microRNA-146a in the blood plasma of patients with CM. Purpose. To determine the possibility and reliability of detecting microRNA-146a in the blood plasma of patients with CM, taking into account the localization of the tumor and its size. Material and methods. The blood plasma of 84 patients was studied mean age 63.4±1.2 years. A control group of 28 people who did not have tumor or chronic autoimmune diseases mean age 63.25±1.43 years. The expression level of miRNA-146a was determined by quantitative PCR. Results. An increase in the level of microRNA-146a was shown, which correlates with the localization and thickness of the tumor. The results were confirmed by statistical analysis. Conclusion. MicroRNA-146a, which increases in plasma levels in patients with CM as its size increases, can be used as a biomarker of aggressive tumor course in terms of hematogenous metastasis. Key words: choroidal melanoma, microRNA-146a, biomarkers.

Objective. To study the energy effect of infusions of the drug Sorbilact in the body of operated patients with cancer of the middle thoracic esophagus. Materials and methods. Clinical use of the drug Sorbilact was performed in 30 operated patients with cancer of the middle thoracic esophagus (the main group). Sorbilact was administered intravenously immediately after surgery, drip at a rate of 30 drops per minute for 5 days at a dose of 800 ml per day. Plasma urea concentration was determined before infusions on the 1st day after surgery, and on days 2, 3, 5 after Sorbilact infusions. The control group – 25 operated patients – was administered 5 % glucose solution at a dose of 800.0 ml. Results and discussion. In the first days after surgery in patients with cancer of the middle thoracic esophagus an increase in the concentration of urea in blood plasma was revealed. In the main group of operated patients after resection of the middle thoracic esophagus in repeated studies on the 2nd, 3rd, 5th day after infusions a significant decrease in the concentration of urea in blood plasma was showed. It indicates that less endogenous protein is consumed for energy purposes, and the caloric needs of the operated body are covered by intensive absorption of Sorbilact, which reduces the catabolism of internal proteins, resulting in reduced nitrogen production, which is manifested in a decrease in the concentration of urea in blood plasma and its difference. In the control group of operated patients in repeated studies on the 2nd, 3rd, 5th day after infusions an increase in plasma urea was revealed, which indicates insufficient caloric energy expenditure of the operated organism. Conclusions. Intravenous infusions of the drug Sorbilact according to the indicator of increment of urea in blood plasma in operated patients after resection of the middle thoracic esophagus in the early postoperative period show a pronounced energy effect.

AbstractUterine fibroids (UF) is the most common (about 70% cases) type of gynecological disease, with the recurrence rate varying from 11 to 40%. Because UF has no distinct symptomatology and is often asymptomatic, the specific and sensitive diagnosis of UF as well as the assessment for the probability of UF recurrence pose considerable challenge. The aim of this study was to characterize alterations in the lipid profile of tissues associated with the first-time diagnosed UF and recurrent uterine fibroids (RUF) and to explore the potential of mass spectrometry (MS) lipidomics analysis of blood plasma samples for the sensitive and specific determination of UF and RUF with low invasiveness of analysis. MS analysis of lipid levels in the myometrium tissues, fibroids tissues and blood plasma samples was carried out on 66 patients, including 35 patients with first-time diagnosed UF and 31 patients with RUF. The control group consisted of 15 patients who underwent surgical treatment for the intrauterine septum. Fibroids and myometrium tissue samples were analyzed using direct MS approach. Blood plasma samples were analyzed using high performance liquid chromatography hyphened with mass spectrometry (HPLC/MS). MS data were processed by discriminant analysis with projection into latent structures (OPLS-DA). Significant differences were found between the first-time UF, RUF and control group in the levels of lipids involved in the metabolism of glycerophospholipids, sphingolipids, lipids with an ether bond, triglycerides and fatty acids. Significant differences between the control group and the groups with UF and RUF were found in the blood plasma levels of cholesterol esters, triacylglycerols, (lyso) phosphatidylcholines and sphingomyelins. Significant differences between the UF and RUF groups were found in the blood plasma levels of cholesterol esters, phosphotidylcholines, sphingomyelins and triacylglycerols. Diagnostic models based on the selected differential lipids using logistic regression showed sensitivity and specificity of 88% and 86% for the diagnosis of first-time UF and 95% and 79% for RUF, accordingly. This study confirms the involvement of lipids in the pathogenesis of uterine fibroids. A diagnostically significant panel of differential lipid species has been identified for the diagnosis of UF and RUF by low-invasive blood plasma analysis. The developed diagnostic models demonstrated high potential for clinical use and further research in this direction.

IntroductionIn recent years, medical treatment for cancer has improved, thereby increasing the life expectancy of patients with cancer. Hence, the focus in healthcare shifted towards analysing treatments that offer to decrease distress and improve the quality of life of patients with cancer. The psychological burden of patients with cancer originates from all kinds of psychosocial challenges related to diagnosis and treatment. Cancer counselling centres (CCounCs) try to address these concerns. However, the current literature lacks research on the effectiveness of CCounCs. This study aims to assess the effectiveness of CCounCs with regard to distress and other relevant psychosocial variables (quality of life, anxietyand so on).Methods and analysisThis prospective observational study with a non-randomised control group has three measurement points: before the first counselling session (baseline, t0) and at 2 weeks and 3 months after baseline (t1, t2). Patients and their relatives who seek counselling between December 2018 and November 2020 and have sufficient German language skills will be included. The control group will be recruited at clinics and oncological outpatient centres in Hamburg. Propensity scoring will be applied to adjust for differences between the control and intervention groups at baseline. Sociodemographic data, medical data and counselling concerns are measured at baseline. Distress (distress thermometer), quality of life (Short Form-8 Health Survey, European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire-Core 30), anxiety (Generalized AnxietyDisorder-7), depression (Patient HealthQuestionnaire-9) and further psychosocial variables are assessed at all time points. With a total of 787 participants, differences between the intervention and control groups of a small effect size (f=0.10) can be detected with a power of 80%.Ethics and disseminationThe study was registered prior to data collection with the German Registration of Clinical Trials in September 2018. Ethical approval was received by the local psychological ethical committee of the Center for Psychosocial Medicine at the University Medical Centre Hamburg-Eppendorf in August 2018. The results will be published in peer-reviewed journals.Trial registration numberDRKS00015516; Pre-results.

In this study, experimentally lindane-induced histopathological changes and proliferation and/or apoptosis in germ cells in the rat testes were investigated. A total of 40 healthy fertile 3-month-old male rats were used. Animals were divided into 4 groups, each containing 10 rats. Group 1 (control) was given only pure olive oil, Groups 2, 3 and 4 were administered lindane at 10, 20 and 40 mg/kg/bw, respectively, by gastric gavage for 30 days. Microscopically, degenerative changes were observed in the lindane-treated groups. For proliferative activity PCNA immunolabelling and for germ cells apoptosis TUNEL methods were performed. Although a strong PCNA positivity in the control group was observed, a gradual decrease was noted in the lindane-treated groups especially at higher doses. Significant increases of apoptosis were seen in the lindane-treated groups compared to the control group. A decrease in testosterone concentrations was observed in lindane-treated groups compared to the control group. The study indicates that high-dose lindane intoxication contributes to the suppression of spermatogenesis through a reduction of germ cell proliferation and an increase of germ cell death in rat testes.

The present study was carried out to investigate the efficacy of eye movement desensitization and reprocessing (EMDR) therapy in treating pain and subjective distress of patients with cancer. A randomized controlled trial was performed on patients with cancer suffering from moderate to severe cancer pain in Yasuj, Iran, in 2019 and 2020. Sixty patients aged 30–60 years who fulfilled the inclusion criteria were selected using a consensus sampling technique. Patients were randomly assigned to EMDR therapy or control groups based on random block allocation. EMDR therapy was administered in six to eight daily 1-hour sessions. The control group received the standard treatment provided by the hospital. A Numeric Pain-Rating Scale (NRS) and the Subjective Units of Disturbance Scale (SUDS) were used to assess pain and subjective distress before and after the intervention in each session. The collected data were analyzed by descriptive statistics, chi-square test, and independent t test using Statistical Package for the Social Sciences (SPSS) version 24. The mean pain intensity and subjective distress score in the experimental group before and after the EMDR intervention were significantly reduced (p < .001). In the control group, no decreases in NRS and SUDS scores occurred at any time (p > .05). Differences in pain scores between the groups were statistically significant (p < .001). EMDR can effectively and sustainably reduce the pain and subjective distress experienced by patients with cancer. Thus, EMDR is a recommended therapeutic option to mitigate pain and subjective distress among patients with cancer.

The research aimed to determine the effect of a mixture of low molecular weight organic acids and complex phytobiotics when replacing a feed antibiotic with them on the activity of digestive enzymes in the duode-nal chyme and the activity of pancreatic enzymes in the blood plasma of young stock B5 and B9 meat chicken lines. The experiments were carried out on the original lines of meat poultry lines B5 (Cornish) and B9 (Plymouth rock). There was an operation to insert a cannula into the duodenum at the age of 6 weeks. The enzymatic activity of the duodenum chyme and the content of pancreatic enzymes in the blood plasma in the groups of chickens receiving antibiotics, low molecular weight organic acids, and phytobiotics with the diet. The data showed that the influence of feed additives on the physiological status of poultry was different. The use of low molecular weight organic acids of the B5 and B9 chicken lines had a significant effect on the production of digestive enzymes due to an increase in the activity of chyme lipase (by 98.3%) and blood plasma lipase (by 26.6%) in B9 chickens and an increase in chyme proteases (by 30.9%) in B5 chickens compared with the control group, where the antibiotic was used. The introduction of complex phytobiotics into the diet had a negative effect on chickens of the B5 line (Cornish), reducing the activity of amylase and lipase of the duodenal chyme (by 29.2 and 26.9%) compared with the control group. In B9 (Plymouth rock) chickens, only the chyme amylase activity increased by 30.8% that indicates an improvement in the availability of feed carbohydrates. These data confirm the need to take into account the different effects of feed additives on the digestion processes in different poultry crosses.

Objective: to study the importance of cytokines, hepcidin, a soluble transferrin receptor, iron metabolism in the development of anemia of chronic diseases in patients with malignant neoplasms and rheumatic pathology, to identify the leading factors in the development of anemia for each of the studied groups and to develop a working classification of anemia of chronic diseases.Materials and methods. 63 patients with rheumatic pathology were examined. The study group included 41 (17 men/24 women, average age 53.4 ± 4 years) patients with anemia, the control group included 22 (9 men/13 women, age 49.3 ± 1.78 years) patients without anemia. The patients (n = 63) with stage II–IV malignant neoplasms were examined. The study group included 41 patients with anemia (34 men/7 women, age 67.1 ± 9.9 years), in the control group 22 patients without it (17 men/5 women, age 60.2 ± 14.9 years). The number of red blood cells, the hemoglobin level, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, concentrations of serum iron, total iron binding capacity (TIBC), ferritin, transferrin, C-reactive protein (CRP), transferrin saturation index (TSI), and soluble transferrin receptor (sTfR), hepcidin, interleukin (IL) – 6, – 10, tumor necrosis factor-α (TNF-α) were determined. Mann – Whitney U Test was applied to check for statistically significant differences in study samples.Results. Compared with the control group, elevated concentrations of ferritin, CRP, hepcidin, sTfR and IL-6 (p <0.05) were found for patients with rheumatic pathology and anemia and no differences were found in the concentrations of iron, TIBC, TSI, transferrin. For patients with solid malignant neoplasms and anemia, lower concentrations of iron, TIBC, TSI and higher concentrations of CRP, hepcidin, sTfR, IL-6, IL-10, TNF-α (p <0.05) are shown in comparison with the control group and there were no differences in the concentrations of ferritin, transferrin (p >0.05).Conclusion. The multicomponent anemia genesis in patients with cancer and rheumatic pathology is shown. The contribution of each mechanism to the development of anemia may vary depending on the specific nosological form. In patients with cancer, functional iron deficiency, activation of IL-6, IL-10, TNF-α synthesis and an increase in hepcidin synthesis lead to the development of anemia of chronic diseases. In patients with a rheumatic profile and anemia, a more pronounced synthesis of hepcidin and an increase IL-6 concentration are indicated. A working version of the classification of anemia of chronic diseases based on the leading pathogenetic factor is proposed (with a predominant iron deficiency, with impaired regulatory mechanisms of erythropoiesis, with insufficient production of erythropoietin).

Background: To study the effects of long non-coding ribonucleic acid (lncRNA) HOX transcript antisense intergenic RNA (HOTAIR) on the proliferation and apoptosis of malignant melanoma cells, and to explore its specific regulatory mechanism through the nuclear factor-κB (NF-κB) signaling pathway. Methods: LncRNA HOTAIR small-interfering RNAs (siRNAs) were designed and synthesized, and the effects of si-HOTAIR transfection on the proliferation and apoptosis of malignant melanoma cells were detected via cell counting kit-8 (CCK-8) assay, 4',6-diamidino-2-phenylindole (DAPI) staining assay and flow cytometry, respectively. The gene expressions were determined using quantitative reverse transcription-polymerase chain reaction (qRT-PCR), the changes in NF-κB pathway-related proteins and apoptosis-associated proteins after interference in lncRNA HOTAIR were detected via Western blotting, and the level of NF-κB in each group was determined via ELISA. Results: The results of CCK-8 assay revealed that the cell proliferation rate significantly declined gradually in si-HOTAIR group compared with that in si-NC group and control group (P<0.05). The results of Western blotting and ELISA showed that the activity of NF-κB in si-HOTAIR group was weakened (P<0.05), suggesting that down-regulation of HOTAIR can suppress the activity of NF-κB. Compared with si-NC group and control group, si-HOTAIR group had remarkably increased gene and protein expressions of pro-apoptotic Bax, and remarkably decreased gene and protein expressions of anti-apoptotic Bcl-2 (P<0.05), demonstrating that down-regulation of HOTAIR can promote apoptosis. Conclusion: Down-regulation of lncRNA HOTAIR can inhibit the proliferation and promote the apoptosis of malignant melanoma cells and suppress the NF-κB pathway.

Purpose: To investigate the effects of Qijin granules on high glucose-induced proliferation and apoptosis in rat glomerular mesangial cells (MC).Methods: MC cells from rats were passaged and cultured, and randomly divided into control group (CNG), high glucose group (HGG), Western medicine group (WMG, high glucose + Benazepril + Gliquidone), and Qijin granules 1/2/3 group (high glucose + different doses of Qijin granules). Mesangial cells proliferation was measured using MTT assay. The NF-κB, MCP-1 and inflammatory factors in supernatant were determined by ELISA. Apoptosis rate and cell cycle were assessed by flow cytometry. The apoptosis-related TGF-β1/Smad signaling pathway-related protein expressions were measured by Western blot.Results: The A-value and early apoptosis rate, apoptosis rate and S-phase percentage, and protein expressions of NF-κB, MCP-1, IL-6, IL-2, TNF-ɑ, Bax, Cyt-C, caspase-3, TGF-β1, and p-Smad3 of MC cells in the HGG at 12 h, 24 h and 48 h were higher than those in the CNG. The above indices were lower in the WMG, and Qijin granules 1/2/3 groups than in the HGG. The Bcl-2, Smad7 protein expression level and the percentage of G1 and G2/M phase were lower in the HGG than in the CNG, and the above indeices were higher in the WMG and Qijin granules 1/2/3 group than in HGG.Conclusion: Qijin granules can dose-dependently inhibit high glucose-induced proliferation and apoptosis in rat MC cells, block the cell cycle and reduce inflammatory responses. This may be related to the regulation of NF-κB, MCP-1 and TGF-β1/Smad signaling pathways. These findings provide theoretical and experimental basis for the clinical treatment of early diabetic nephropathy.

Abstract Objective: to study the association between high activity of Factor II (prothrombin) in blood plasma with G20210A mutation and the development of great obstetrical syndromes.Material and methods: A prospective clinical cohort study was conducted on 290 pregnant women (average age 31.7±4.7 years old). The main group was made up of 140 G20210A patients, while the control group comprised 150 women with the wild G20210G type. The aim was to evaluate the activity of Factor II in the venous blood plasma during the stages of pregnancy with regard to trophoblast invasion waves. As per results, association analysis of Factor II activity value and gestational complications was carried out.Results: In the control group, the median (Me) of Factor II activity ranged from 108% (preconception period) to 144% (pregnancy) [95% CI 130-150]. In patients with the GA type, the value was significantly higher in related periods, ranging from 149% to 181% [95% CI 142-195], p<0.0001. With Factor II activity ranging from 148.5% to 180.6%, pregnancies in the main group had no complications. Higher levels of Factor II activity were associated with the development of early and/or severe preeclampsia (PE) and fetal growth retardation (FGR).Conclusion: The data obtained regarding Factor II activity in blood plasma, juxtaposed with the development of great obstetrical syndromes, allow to assume that manifestation of G20210A in early and/or severe PE and FGR is associated with this coagulation factor's level of activity. Threshold value of the Factor II activity with G20210A mutation, allowing to predict the development of PE, comprised 171.0% at the preconception stage (AUC – 0.86; p<0.0001) and within 7-8 weeks of gestation it was 181.3% (AUC – 0.84; p<0.0001).
