Background. Mucopolysaccharide polysulphate (MPS) has been used in medicine as an anti-inflammatory and antithrombotic agent for over 50 years. Its chemical structure permits considerable hydrogen bonding with adjacent water molecules, which effectively leads to hydration of the surrounding tissue. In addition, it stimulates endogenous hyaluronate synthesis, resulting in an increase in water-binding capacity and viscoelasticity of the skin.Objective. To study the efficacy of 0.1% MPS on hydration and elasticity of human skin.Methods. The first part of this study was a randomized double blind placebo-controlled study which included 60 female volunteers aged 30–45 years with dry skin, defined by Corneometer CM 825. The volunteers were treated with either 0.1% MPS or vehicle control. All subjects were asked to apply 1 g of cream to their face twice daily for a total period of 4 weeks. Skin hydration and elasticity were measured at baseline and week 4 with Corneometer CM 825 and cutometer MPA 580, respectively, at forehead and both cheeks. The second part of this study focused on the efficacy of 0.1% MPS on skin hydration after single application. 20 female volunteers aged 30–45 years with dry skin, defined by Corneometer CM 825, were recruited to the study. All subjects were asked to apply 2 g of 0.1% MPS cream on entirely randomly selected forearm. Skin hydration at the middle of both forearms was measured at baseline, immediately after application, and every 1 hour after application for a period of 10 hours.Results. 57 subjects (28 in vehicle control group, 29 in MPS) completed treatment protocol. The baseline skin hydration of both groups was not significantly different (P=0.47). Hower, there was a statistically significant difference in skin hydration at 4 weeks between MPS and placebo group (P=0.01). Skin elasticity was significantly improved at week 4 in both groups (vehicle-control,P<0.01, and MPS,P<0.01). However, no significant difference in skin elasticity between MPS and vehicle-control group was noted (P=0.15). Lastly, there was a statistically significant improvement in skin hydration after a single application (P<0.01). This improvement was maintained for 10 hours.Conclusions. MPS provided improvement of skin hydration but not skin elasticity in woman with dry skin, compared with vehicle control. And MPS improved the skin hydration for at least 10 hours after single application.

This study investigated the hair regeneration promotion and hair loss prevention properties of Nelumbinis Semen (NS) extract in vitro and in vivo. The effect of NS on the proliferation and migration of human dermal papilla cells (hDPCs) was measured in vitro via CCK-8 and scratch migration assays, after which the antioxidant activity of NS was also quantified. NS extracts were then applied to the back of 7-week-old C57BL/6 mice for 3 weeks to monitor hair growth patterns and hair follicle (HF) histology. The mice were divided into three groups: negative control group (NC; DMSO), positive control group (PC; 3% minoxidil), and experimental group (NS extract 1,000 ppm). Moreover, to study the molecular mechanisms by which NS extract regenerates hair growth, real-time PCR was used to analyze factors related to the hair growth cycle. The NS extracts were found to possess high antioxidant properties due to their high flavonoid contents and electron-donating ability. Moreover, NS extracts enhanced hDPC proliferation and migration in a concentration-dependent manner (15.63–125 ppm). The hair growth index and growth area of the NS group (2.81 score, 81%) on day 14 were higher than those of the PC group (2.65 score, 68%) ( p < 0.05 ). Additionally, the HFs of the NS group were located deep in the subcutis, similar to the PC group with developed hair roots. Moreover, the mRNA expression of VEGF and IGF-1 was higher in the NS group compared to the PC group, whereas TGF-β1 expression was lower ( p < 0.05 ). Our findings indicate that NS modulates hair growth by increasing IGF-1 and VEGF expression while inhibiting that of TGF-β1. Therefore, our findings suggest that NS extract is a promising new hair loss treatment derived from a natural substance that helps promote hair growth and prevent hair loss.

Intake of oral supplements with the aim of a cutaneous antiaging effect are increasingly common. Hyaluronic acid (HA) is a promising candidate, as it is the key factor for preserving tissue hydration. In our practice study, we evaluated the effect of an oral HA preparation diluted in a cascade-fermented organic whole food concentrate supplemented with biotin, vitamin C, copper, and zinc (Regulatpro Hyaluron) on skin moisture content, elasticity, skin roughness, and wrinkle depths. Twenty female subjects with healthy skin in the age group of 45 to 60 years took the product once daily for 40 days. Different skin parameters were objectively assessed before the first intake, after 20 and after 40 days. Intake of the HA solution led to a significant increase in skin elasticity, skin hydration, and to a significant decrease in skin roughness and wrinkle depths. The supplement was well tolerated; no side effects were noted throughout the study.

Relevance. Information about the cardiovascular diseases risk factors (CVD RF) for in men with chronic lung inflam-matory pathology (CLID) is contradictory and requires clarification. Aim. To evaluate the peculiarities of CVD RF in men under 60 years of age with CLID in myocardial infarction (MI) to improve prevention. Material and methods. The study included men aged 19-60 years old with type I myocardial infarction. Patients are divided into two age-comparable groups: I - the study group, with CLID - 142 patients; II - control, without it - 424 patients. A comparative analysis of the frequency of observation of the main and additional cardiovascular risk fac-tors in groups was performed. Results. In patients of the study group, more often than in the control group we observed: hereditary burden of is-chemic heart disease (40.8 and 31.6%, respectively; p = 0.0461) and arterial hypertension (54.2 and 44.6%; p = 0.0461), frequent colds (24.6 and 12.0%; p = 0.0003), a history of extrasystoles (19.7 and 12.7%; p = 0.04); chronic foci of infections of internal organs (75.4 and 29.5%; p˂0.0001), non-ulcer lesions of the digestive system (26.1 and 14.6%; p = 0.007), smoking (95.1 and 66.3%; p˂0.0001), MI in winter (40.8 and 25.9%; p = 0.006). Less commonly were observed: oral cavity infections (9.2 and 23.6%; p˂0.0001); hypodynamia (74.5 and 82.5%; p = 0.0358), over-weight (44.4 and 55.2%; p = 0.0136), a subjective relationship between the worsening of the course of coronary heart disease and the season of the year (43.7 and 55.2%; p = 0.0173) and MI - in the autumn (14.1 and 21.9%; p = 0.006) period. Conclusions. The structure of CVD RF in men under 60 years of age with CLID with MI is characterized by the pre-dominance of smoking, non-ulcer pathology of the digestive system, frequent pro-student diseases, meteorological dependence, a history of cardiac arrhythmias and foci of internal organ infections. It is advisable to use the listed factors when planning preventive measures in such patients.

Diabetes Nephropathy

The prevalence of DM in Riskesdas in 2018 according to the Perkeni consensus in 2015 is higher than according to the Perkeni consensus in 2011, the prevalence was10.9%. The disease can develop into diabetes nephropathy, Increased prevalence of diabetic nephropathy directly proportional with an increase in diabetes prevalence. Diabetic nephropathy is a microvascular complication in diabetics that develops around 30% in patients with type I DM and about 40% in patients with type II DM. Turmeric extract has antioxidant and anti-inflammatory effects to prevent the bad development of diabetes nephropathy. This study looked at the effect of giving a combination of noni and turmeric extract on histopathology of alloxan-induced renal rats. A total of 25 mice were divided into 5 treatment groups, namely the PI group (250 mg / kgBB extract dose), PII group (500 mg / kgBB extract dose), PIII group (750 mg / kgBB extract dose), positive control group (glibenklamid) and negative control group (without extract and glibenklamid). The study used Post Test Only Group. The highest percentage decrease in blood glucose in the PI group was 56.11% and the lowest decrease in the PIII group was 24.12% with p = 0.012. The results of the study were not based on the number of extract doses. The measurement results of rat body weight and glomerular diameter were not affected by blood glucose level with p = 0.700 for body weight and p = 0.187 for glomerular measurement results.

Gymnema sylvestre of the family Asclepiadaceae is one of the most important medicinal plants of the central eco-region. It is popularly known as Gurmar, which means “sugar killer”. Extract of leaves is reported to have tannins, gum, flavonoids, proteins and saponins. It has displayed a wide array of pharmacological activities. This study was aimed to investigate the antidiabetic and hypolipidemic effects of Gymnema sylvestre extract in experimentally induced diabetes in rats. Diabetes was produced in adult Wistar rats with single dose of streptozotocin (STZ) @ 60 mg/kg b.wt. intraperitoneally. After the confirmation of diabetes on 7th day (sugar >200 mg/dl), alcoholic and aqueous extracts of G. sylvestre (400 mg/kg) were administered orally to the experimental rats from 8th day and continued for 42 days thereafter. The antidiabetic and hypolipidemic activity was estimated by measuring blood glucose, lipid profile and histopathological examination of various tissues from all the groups. Administration of STZ resulted in a significant (p less than 0.01) increase in blood glucose and lipid profile and histopathological alterations in Diabetic control group as compared to healthy control group. Gymnema treatment demonstrated significant (p less than 0.01) antidiabetic effect indicated by restoration of blood glucose compared to STZ control group. The study concluded that extracts of Gymnema sylvestre improved the altered glucose and lipid profile in diabetic rats, suggesting that the Gymnema Sylvestre extracts exhibit the antidiabetic and hypolipidemic activity.

AbstractCollagen-type I alpha 1 chain (COL1A1) and COL1A2 are abnormally expressed in intracranial aneurysm (IA), but their mechanism of action remains unclear. This study was performed to investigate the mechanism of COL1A1 and COL1A2 affecting the occurrence and rupture of IA. Quantitative real-time polymerase chain reaction was used to measure the expression of hsa-miR-513b-5p, COL1A1, COL1A2, TNF-α, IL-6, MMP2, MMP3, MMP9 and TIMP4 in patients with ruptured IA (RA) (n = 100), patients with un-ruptured IA (UA) (n = 100), and controls (n = 100). Then, human vascular smooth muscle cells (HASMCs) were cultured, and dual luciferase reporter assay was performed to analyse the targeting relationship between miR-513b-5p and COL1A1 or COL1A2. The effects of the miR-513b-5p mimic and inhibitor on the proliferation, apoptosis, and death of HASMC and the RIP1-RIP3-MLKL and matrix metalloproteinase pathways were also explored. The effect of silencing and over-expression of COL1A1 and COL1A2 on the role of miR-513b-5p were also evaluated. Finally, the effects of TNF-α on miR-513b-5p targeting COL1A1 and COL1A2 were tested. Compared with those in the control group, the serum mRNA levels of miR-513b-5p, IL-6 and TIMP4 were significantly decreased in the RA and UA groups, but COL1A1, COL1A2, TNF-α, IL-1β, MMP2, MMP3 and MMP9 were significantly increased (p < 0.05). Compared with those in the UA group, the expression of COL1A1, COL1A2, TNF-α, IL-1β and MMP9 was significantly up-regulated in the RA group (p < 0.05). Results from the luciferase reporter assay showed that COL1A1 and COL1A were the direct targets of miR-513b-5p. Further studies demonstrated that miR-513b-5p targeted COL1A1/2 to regulate the RIP1-RIP3-MLKL and MMP pathways, thereby enhancing cell death and apoptosis. Over-expression of COL1A1 or COL1A2, rather than silencing COL1A1/2, could improve the inhibitory effect of miR-513b-5p on cell activity by regulating the RIP1-RIP3-MLKL and MMP pathways. Furthermore, over-expression of miR-513b-5p and/or silencing COL1A1/2 inhibited the TNF-α-induced cell proliferation and enhanced the TNF-α-induced cell death and apoptosis. The mechanism may be related to the inhibition of collagen I and TIMP4 expression and promotion of the expression of RIP1, p-RIP1, p-RIP3, p-MLKL, MMP2 and MMP9. MiR-513b-5p targeted the inhibition of COL1A1/2 expression and affected HASMC viability and extracellular mechanism remodelling by regulating the RIP1-RIP3-MLKL and MMP pathways. This process might be involved in the formation and rupture of IA.

Abstract Background Many therapeutic options are currently available for facial skin rejuvenation, but little evidence exists about the efficacy of combining such procedures. Objectives To assess and investigate the synergic effect of HA and a-PRP injections on facial skin rejuvenation. Methods For this randomized controlled prospective study, 93 eligible patients were enrolled and randomized into three intervention groups to undergo a series of three treatments sessions with either a-PRP, HA or Cellular Matrix-BCT-HA (PRP-HA) injected on facial cheeks. Results A total of 93 patients were included. Treatment with Cellular Matrix BCT-HA led to a very significant improvement in the overall facial appearance compared to groups treated with a-PRP and HA alone (p&lt;0.0001). Participants treated with Cellular Matrix showed a 20%, 24% and 17% increase in FACE-Q score at 1 month, 3 months and 6 months post-treatment, respectively. For the HA group, the improvement of FACE-Q score was 12%, 11% and 6% at 1, 3- and 6-months post-treatment, respectively, while the a-PRP group showed a 9% improvement in FACE-Q score at 1 month and 11% and 8% improvement at 3- and 6-months post-treatment, respectively.Biophysical measurements showed significantly improved skin elasticity for the group Cellular BCT-HA compared to a-PRP and HA alone. No serious adverse events were reported. Conclusions Combining a-PRP and HA seems to be a promising treatment for facial rejuvenation with a very significant improvement in facial appearance and skin elasticity compared to a-PRP or HA alone.

Background:Type I interferons (IFN-Is) are a group of molecules with pleiotropic effects on the immune system forming a crucial link between innate and adaptive immune responses. The type I interferon pathway has been implicated in the pathogenesis of a number of rheumatic diseases, including rheumatoid arthritis. IFN activity is usually quantified using expression of interferon-stimulated genes (ISGs) referred to as an IFN signature. Acellbia (BIOCAD) is the first Russian rituximab (RTX) biosimilar which was approved for medical use in rheumatoid arthritis (RA) patients in Russia and some CIS countries.Objectives:To evaluate the changes in expression of ISGs in patients (pts) with RA during RTX biosimilar therapyMethods:20 RA pts (18 woman, Me;IQR age 61.5(54-66.5) years, disease duration 39.5(20-84) months, mean DAS 28 5.6(4.9-6.8)) received two intravenous RTX biosimilar infusions (600 mg №2) in combination with DMARDs and glucocorticoids. Laboratory biomarkers were assessed at baseline and 24 weeks after the first infusion of RTX. 5 genes (IFI44L, MX1, IFIT 1, RSAD2, EPSTI1) were selected for evaluation of the “interferon signature” (Type I IFN gene signature – IFNGS). IFI44L and IFIT1 expression was undetectable, therefore the remaining three genes (MSX1, EPSTI1, RSAD2) were included into further analysis. IFNGS was calculated as the average expression values of the three selected genes. The control group included 20 age and gender matching healthy donors.Results:The baseline expression levels of MX1-11.48 (5.45-19.38), EPSTI1-12.83 (5.62-19.64), RSAD2-5.16 (2.73-10.4), and IFNGS-10.3 (5.18-17.12) in RA patients were significantly higher compared to healthy donors– 1,26 (0,73-1,6); 1,06 (0,81-1,48); 0,93 (0,72-1,19); 1,09 (0,92-1,42), (p<0.05, respectively). IFNGS was detected in 15 (75%) patients, and was not found in 5 (15%) patients. RTX induced reduction in disease activity, and the level of acute phase reactants (ESR, CRP) after 12 and 24 weeks of therapy, p<0.05 (fig.1). Increased RSAD 2 expression (p<0.05) and a trend to increasing IFNGS levels (p=0.06) were documented in the whole group, and also in patients with moderate treatment effects by week 24. Among patients with a good EULAR response to therapy, changes in expression were not significant (p> 0.05) (fig.1)Figure 1.Conclusion:Expression of IFN-stimulated genes was increased in RA patients compared to healthy donors. Increased RSAD2 and IFNGS expression was documented in patients with moderate effect of RTX therapy, therefore, these findings have important clinical relevance as predictors of RA clinical course which necessitates personified approach to treatment.Disclosure of Interests:None declared
