Purpose. The effectiveness of classical and eversion carotid endarterectomy (CE) in patients with cerebral ischemia in atherosclerotic stenosing carotid artery disease (ICA) was compared in the article.
Material and methods. The examination and analysis of data of 122 patients with more than 60% ICA stenosis was held: men — n = 92 (60.1%), women n = 61 (39.9%). The average age was 52.3 years (ranged from 34 to 74 years). All the patients were symptomatic. 92 patients underwent an eversion endarterectomy (CE), 30 patients underwent classical CE.
The effectiveness of surgical treatment was assessed by the dynamics of the neurological status, the change in the parameters of duplex and transcranial studies before the operation, on day 10, at 1, 3, 6, 9 months, 1, 1.5, 2, 3 years.
Results. In patients who underwent eversion CE, in the early postoperative period, a significant decrease in the asymmetry coefficient was revealed in the study of background LSC valuesdue to an increase in the blood flow velocity in the ipsilateral middle cerebral artery (MCA) and a decrease in the linear velocity of the blood flow (LVBF) in the posterior cerebral artery (PCA) on the side of the initially stenotic ICA on the background of improvement of hemodynamic conditions in all cases (p < 0.05). In patients, a significant increase in the reactivity factor for the hypercapnic load from the initial value was noted against the background of approaching the normative indices of the pulsation index. The latent period of vascular reactivity was shortened to 24.3 ± 3.7 seconds. In patients who underwent classical CEAE n = 30, in early terms of up to 1 month, a decrease in the coefficient of asymmetry of LVBF was noted due to the normalization of the velocity characteristics of cerebral blood flow in all the main cerebral vessels of the carotid and vertebrobasilar basins. Comparative analysis of the spectral expansion (SE) values obtained initially and recorded in groups with different types of surgical intervention revealed a significant difference in the resulting data (p < 0.05). Restoration of SE parameters to normative ones was registered in the group of classical CEA in 26.7% (n = 8) and 79.3% (n = 73) with an eversion EAE for 1 month. The maximum rate of positive dynamics was traced during the first month after cerebral revascularization, complete recovery was recorded at the end of the 18th month in the group of eversion CE and 24 months in the group of classical CE. There were no significant differences in the resultant indices of regression of neurological disorders in the postoperative period of an eversion EAE and classical EAE (p > 0.05).
With the eversion CE, the total number of complications was n = 9 (9.8%), and 1 (1.1%) case — restenosis in the reconstruction zone. In the case of classical CE, the total number of complications was n = 10 (33.3%), of which n = 1 (3.3%) cases of hyperperfusion syndrome were observed; in n = 2 (6.6%) patients, development of a stroke, 1 (3.3%) developed myocardial infarction. Restenosis in the reconstruction zone was formed in n = 2 (6.6%) patients, peripheral nerve damage was in n = 4 (13.3%) patients.
Conclusions. Classic and eversion CE are both effective. Short- and long-term clinical and hemodynamic results of surgical treatment by the method of eversion of the CE are somewhat better than the results of classical one.
Classical CE is indicated in cases of extended plaque, eversion of the CE is indicated in the cases of short local plaques.

Purpose. Investigation of the effect of the Metronizatol on the biological effect of Doxirubicin.
Materials and methods. The studies were performed in the CBA/Lac males and C57Bl/6 females mice grafted with melanoma B16 and mucinous ovarian cancer CaO‑1. Metronidazole and Doxorubicin were used in the work. The antitumor effect was assessed by tumor volume and inhibition of tumor growth.
Results. The data obtained indicate that Metronidazole used in oncologic practice for the treatment and prevention of infectious complications, and as a radiosensitizer, can enhance the antitumor effect of Doxorubicin, but this effect is accompanied by a significant increase of the cytostatic toxicity. These effects are leveled by increasing the interval between injections of Metronidazole and Doxorubicin up to 4 hours.
Conclusion. The enhancement of the antitumor activity of Doxorubicin under the influence of Metronidazole depends on the interval between the administration of these drugs. When Metronidazole is used in cancer patients, the possibility of enhancing the toxic effect of cytostatics should be considered when they are simultaneously exposed. Patients receiving chemotherapy should be administered antitumor drugs no earlier than 4 hours after exposure to Metronidazole.

Objective. Assessment of the rectal cancer (RC) incidence and stage structure trends in the Arkhangelsk region (AR), Russia before and after implementation of national programs for health system reforming based on population data of the Arkhangelsk Regional Cancer Registry (ARCR) over the period 2000–2015.
Materials and methods. Anonymized data on all cases of RC (C19.0‑C21.0) in the AR in 2000–2015 were extracted from the database of the ARCR. Over the study period, 3721 cases of the RC were selected. Age-standardized (ASR) RC incidence rate was calculated. Population number and its age distribution were taken from the Regional Bureau of Statistics, Arkhangelskstat. Time trends were analyzed using segmented regression.
Results. Over the period, an incidence (ASR) of RC in AR increased from 11.5 to 14.2 per 100000. The incidence rates in the male population were higher than in women: 20.3 vs 12.6 in 2015. The growing trend of male incidence was stable. The ASR of RC incidence in female increased significantly by 4.6% per year in 2011–2015. RC ASRs for both urban and rural populations were growing, 12.3 and 20.4 per 100000 in 2015, respectively. StagesI, II, III and IV were established in 14%, 50%, 9% and 21% of cases, however, the stage I in urban residents was detected 4% more often. The proportion of stage I non-significantly varied from 10.6% to 13.3% in 2000–2015. After the introduction of the National Project “Health”, the proportion of the stage IV non-significantly decreased by 5.4% per year, same after the introduction of the All-national Dispensarization it non-significantly increased by 5.4% per year.
Conclusion. Implementation of national programs for health system reforming didn’t provide significant improvement in earlier detection of RC. Introduction of national screening programs is necessary. A higher incidence rates among males and rural population require detailed analysis.
Review
The article discusses modern ideas about the immune therapy of cancer — methods of treatment of oncological diseases based on immunological reactions of the organism to the appearance of malignant cells in it. This area is actively studied in clinical practice in the last decade, and some therapy has already been approved for use by regulators after promising results of clinical trials 3 phase.
Immune therapy is based on antitumor immune cycle — the cascade of processes responsible for the immune system’s response to tumor cells. Involved regulatory mechanisms are targets for various therapies, the overall goal is to restore proper functioning of the cycle and to achieve the elimination of cancer cells.
Currently, the most studied two types of immune therapy — checkpoint inhibitors and adaptive cell therapy. Checkpoint inhibitors increase the activity of body immune cells, reducing the inhibitory influence of the tumor microenvironment and the tumor cells themselves, which allowed them to get out from under the pressure of the immune system during the development of the disease. Adaptive cell therapy, in turn, allows to compensate the lack of active immune against tumor cells.
Mechanisms of action determine the effectiveness of various therapies for different diseases, and for patients inside of one diagnosis. To determine the effectiveness of other treatment prior to a particular patient it is necessary to use the latest achievements in precision medicine, based on the search for new biomarkers and analyzing each patient separately. This approach will significantly reduce costs and save precious time for the patient.

The purpose of the study. The study of morbidity with temporary disability of working officers of the Navy, retired and resigned, as well as affecting the level of certain factors.
Materials and methods. A sociological survey of 574 officers of the Navy, who were dismissed from the Armed Forces to the reserve (resignation), was held. 32.7% of them at the time of the survey have been working.
Results. 48.8% of respondents rated their health at the time of the survey as a good for their age. The level of morbidity with temporary disability (MWTD) in 100 operating reserve (retired) officers amounted to 94 cases. The number of days of temporary disability was equal to 867 days per 100 employed military pensioners. Most long-term treatment (up to 47 days) were required for patients with blood diseases. Analysis of the structure of diseases of reserve (retired) officers leading to temporary disability, showed that the bulk of the cases (63.7 per cent) were diseases of the respiratory organs, in second place were diseases of the circulatory system (24,5%), the third — diseases of the genitourinary system (4.3%). The average number of existing diseases to working military retirees less than idle: 1.9 vs 2.1. The average number of diseases at the single soldiers discharged was significantly more than that of living in family.
Conclusion. The features of level and structure, as well as risk factors of MWTD should be considered in the development and adoption of administrative decisions directed on preservation and strengthening of health of reserve (retired) officers.
Purpose. Assessment of the received emergency medical services (EMS) in patients with cardiological profile in the South Kazakhstan region.
Materials and methods. A sociological study was carried out among three compared groups: group 1 — patients of the regional cardiological center (312); 2nd — those who applied to rural outpatient clinics, polyclinics, hospitals (244), and the 3rd — who applied to the central district hospital (228).
Results. The analysis showed that 65.1% of the respondents applied for EMS over the diseases of the circulatory system, mostly they did it 1–2 times a year (44.9%), less often several times a month (15.1%). Several times a week 5.1% of patients were called to EMS. It was found that in 65.5% of cases there was a rapid arrival of the EMS, less than 20 minutes. It should be noted that a long wait for the arrival of the EMS (45 minutes or more) took place in 10.2% of cases. The waiting time, as the reason for the dissatisfaction of the EMS, was more often called the respondents of the 2 nd and 3 rd groups — 94.1% and 93.9% versus 76.5% in the 1st group (p < 0.05). Inattentive attitude of the staff was more often noted by the patients of the 3rd group, and the low availability of free medication was most often indicated in the 1st group.
Conclusion. The received characteristic of the EMS and its assessment by patients with diseases of the circulatory system should be taken into account when developing a package of measures to optimize cardiac care in the region.
