[An overview of investments in the development of the Russian Medtech market and the prospects for the impact of digitalization in medicine on the economic performance of companies until 2030].

Today, the topic of digitalization, the introduction of innovations based on Big Data, the complexity of technologies due to the introduction of artificial intelligence in medicine and healthcare is one of the most relevant in this industry, undoubtedly contributing to its rapid development. As a result of this development, there is a huge number of services and applications. Internet resources, not only for health tracking (more than 3,500 applications are available by the end of 2023), but also the development of diagnostic resources, telemedicine, etc. Quite quickly, it was the pandemic and its consequences that changed the format of interaction between doctors, communication in the community of doctors, and their interaction with patients. Saving time when making an appointment with a doctor, visiting him, constant monitoring of the condition of patients, becoming better and more multidirectional day by day, make it possible to provide timely, relevant care to more people. The use of artificial intelligence technologies and digital solutions in the field of Russian healthcare opens up great prospects for both doctors and patients, as well as for many government agencies, since the development of regulatory and legal regulation and state control and management of innovations in the field of medicine and healthcare is important. An important factor is that not only government programs for the development of healthcare, but also investments are extremely important for the development of digital medicine.

Role of Glutathione-S-Transferase Family Genes in Male Infertility.

Polymorphisms of xenobiotic detoxification genes GSTT1 and GSTM1 and activity of glutathione system enzymes were studied in men with infertility. The frequency of deletion variant of GSTT1 gene in men with infertility was by 2 times higher than in fertile men. Deletion variant of GSTM1 gene was 1.4-fold more frequent in infertile men than in fertile men. Complete deletion of two genes was found in 19% men with infertility and only in 6% fertile men. The balance of activity of glutathione system enzymes essential for the effective detoxification of exogenous xenobiotics and toxic endogenous metabolites was impaired in infertile carriers of deletion variants of genes. Our results suggest that adaptation mechanisms are disordered in infertile men.

Features of Lipoperoxidation, Antioxidant Defense, and Thiol/Disulfide System in the Pathogenesis of Infertility in Males, Carriers of Nonfunctional Variants of GSTT1 and GSTM1 Gene Polymorphisms.

Comparative analysis of the parameters of LPO, antioxidant defense (AOD), and the thiol/disulfide system was performed in fertile and infertile males of reproductive age carrying different genotypes of the glutathione system genes. Blood plasma, blood hemolysate, and ejaculate served as specimens for biochemical studies. A decrease in glutathione S-transferase activity was found in blood and ejaculate specimens from fertile and infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes. In infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes determining reduced glutathione S-transferase activity, a decrease in the concentration of low-molecular-weight cell antioxidant (reduced glutathione) and an increase in the concentration of secondary LPO products (TBA-reactive substances) were revealed. Identification of carriers the polymorphic GSTT1 and GSTM1 variants and analysis of activity of the thiol/disulfide system enzymes can be recommended for additional evaluation of the risk for reproductive dysfunction in men.

Effect of Preparation Based on Trametes Pubescens Xylotroph Fungi on Lipid Peroxidation in the Blood of Experimental Animals under Conditions of Dark Stress.

Using the model of dark stress caused by animal maintenance at dimmed light we showed that Trametin (product obtained during liquid-phase culturing of Trametes pubescens xylotroph fungi) effectively prevented oxidative stress under conditions of light deprivation. The preparation increased the level of unsaturation of lipids, reduced the concentration of primary and end-products of LPO, and increases both the integral parameter of the antioxidant defense system (total antioxidant activity) and its components (activity of superoxide dismutase and reduced glutathione).

[Character of brain interhemispheric relation in children at forming labile arterial hypertension].

Electroencephalography investigations were carried out twice in 26 schoolchildren in the age of 7-8 years and in the age of 9-10 years. The control group included healthy children: the research group included children in whom in the age of 7-8 years the normal level of arterial pressure was registered, and in whom in the age of 9-10 years labile arterial hypertension was revealed. It is revealed, that in children of younger school age forming of the labile form of arterial hypertension is connected whit infringement of processes of age changes of intercortical and cortical-subcortical interrelations and forming of rigidly integrated system of interhemispheric relations. Its mechanism of realization is carried out due to hyperactivation of the right hemisphere and it is incorporated on preclinical stage.

[Hemoblastosis and leukemia morbidity in the townsfolk of Seversk and of Siberian group of chemical enterprises personnel].

Hemoblastosis and leukemia morbidity has been analyzed in the townsfolk of Seversk (in particular, Seversk residents and Siberian Group of Chemical Enterprises (SGCE) personnel). The standardized relative risk ratios for hemoblastosis morbidity in menes and womens of Seversk were found to be significantly higher in comparison with the regional standard ratios (in 1.8 and 1.5 times correspondingly). Hemoblastosis and leukemia morbidity rate in SGCE males is significantly higher in comparison with the similar regional standard ratios. Leukemia morbidity dependence due to cumulative external gamma-radiation in a dose range up to 1 Sv has not been found in SGCE personnel, without regard to chronic lymphatic leukemia.

Efficacy of supplemental anti-inflammatory therapy with fenspiride in chronic obstructive and nonobstructive bronchitis.

OBJECTIVE: The objective of this randomised, nonblind study was to assess the efficacy of fenspiride as complementary anti-inflammatory therapy in combination with ipratropium bromide in patients with chronic bronchitis (CB). A comparison was made with ipratropium bromide alone, the generally accepted standard therapy for CB. METHODS AND SUBJECTS: The study population comprised 20 patients with chronic obstructive bronchitis (COB) and 60 patients without signs of obstruction. Fifty-one males (64%) and 29 females (36%) aged from 25 to 65 years were studied over a 6-month treatment period. Combined therapy with fenspiride (160 mg/day) and ipratropium bromide (160 mug/day) was prescribed to 39 patients (28 with CB and 11 with COB) for 6 months, and monotherapy with ipratropium bromide (160 microg/day) was prescribed for 41 patients (32 with CB and nine with COB). RESULTS: The combined therapy group had a reduced intensity of dyspnoea, improvements in sputum nature and quantity of exudation, and a reduced intensity of coughing. The monotherapy group showed reductions in sputum exudation and cough intensity. Improvements in lung respiratory function were observed in both groups, but were greater in the combined therapy group of patients. Reduced cytosis, percentage and absolute content of neutrophils, and absolute content of lymphocytes and eosinophils in induced sputum were observed with CB patients in the combined therapy group. A reduced content of lymphocytes and an increase in macrophages were observed with CB patients in the monotherapy group. A significant decline in tumour necrosis factor (TNF)-alpha content in sputum was observed with both therapeutic regimens, although a statistically significant decline in serum TNFalpha (10.85 ng/L to 5.58 ng/L; p = 0.03) and reduced interleukin-8 in sputum (311.94 ng/L to 122.02 ng/L; p = 0.027) were observed with patients given combined therapy. CONCLUSION: The study showed greater efficacy of long-term treatment with fenspiride and ipratropium bromide compared with ipratropium bromide alone in patients with CB. This combination regimen can be recommended for the reduction of inflammation and prevention of disease progression in patients with CB and may also be useful in patients with COB.

[Efficacy of a complementary antiinflammatory treatment with erespal in chronic obstructive and nonobstructive bronchitis]. / Effektivnost' dopolnitel'noi protivovospalitel'noi terapii érespalom pri khronicheskom obstruktivnom i neobstruktivnom bronkhite.

AIM: To compare efficacy of atrovent alone and in combination with erespal in patients with chronic bronchitis (CB) and chronic obstructive pulmonary disease (COPD). MATERIAL AND METHODS: Of 80 participants of the trial (51 male and 29 female--63.75 and 36.25%, respectively) who had CB or COPD, 39 patients (28 with CB and 11 with COPD) received 6-month combined treatment with erespal (160 mg/day) and atrovent (160 mcg/day) and 41 patients (32 with CB and 9 with COPD) received atrovent monotherapy in the same dosage. RESULTS: Combined therapy produced positive changes in dyspnea, sputum characteristics and its discharge, cough, monotherapy improved sputum discharge and relieved cough; pulmonary ventilation improved in both groups especially in those on monotherapy. CB patients showed low cytosis, percentage and absolute count of neutrophils, absolute count of lymphocytes and eosinophils in induced sputum. In CB patients percentage of lymphocytes reduced while count of macrophages went up. Combined treatment including erespal also promoted a significant fall of serum and sputum TNFalpha and IL-8 reduction in the sputum. CONCLUSION: Erespal+atrovent treatment proved more effective than atrovent alone. It is recommended for both CB and COPD patients without marked disorders of external respiration function.
