Objective: Our research was to discuss effects and mechanism of lncRNA TUG1 in NSCLC by vitro study. Methods: A549 and H1299 cells were divided into NC, pcDNA 3.1 and lncRNA TUG1 groups. Measuring cell proliferation using CCK-8 assay, cell apoptosis by flow cytometry, invasion cell number by transwell and wound healing rate by wound healing assay. Relative gene and protein expressions by RT-qPCR and WB assay. Results: Compared with NC group, the cell proliferation rate, invasion cell number and wound healing rate were significantly depressed in A549 and H1299 cell lines (P < 0.001, respectively). By RT-qPCR and WB assay, lncRNA TUG1 gene expression were significantly increased (P < 0.001, respectively); E-cadherin gene and protein expression were significantly up-regulation, and N-cadherin and Vimentin gene and protein expressions were significantly depressed compared with those of NC group in A549 and H1299 cell lines (P < 0.001, respectively). Conclusion: lncRNA TUG1 had effects to suppress NSCLC cell biological activities by regulation EMT relative gene and proteins expression in vivo study.

Pressure ulcer or pressure sore is one of the complications seen in bedridden patients. Management of these ulcers is often challenging. But there is no well-established method that accelerates the wound healing rate. Various adjunctive methods are used for wound bed preparation before definitive reconstruction plan is made. Here we describe our experience in the role of insulin therapy as an adjunct in the management of pressure sores.

Background/Aims: We have developed a mixed-cell sheet consisting of autologous fibroblasts and peripheral blood mononuclear cells with a high potency for angiogenesis and wound healing against refractory cutaneous ulcers in mouse and rabbit models. To increase the effectiveness of the mixed sheet, we developed a multilayered mixed sheet. Methods: We assessed the therapeutic effects of multilayered sheets on cutaneous ulcers in mice. Growth factors and chemokines were assessed by enzyme-linked immunosorbent assay. Angiogenesis and fibroblast migration were measured by using tube formation and migration assays. Wound healing rate of cutaneous ulcers was evaluated in mice with diabetes mellitus. Results: The concentration of secreted vascular endothelial growth factor, hepatocyte growth factor, transforming growth factor, C-X-C motif chemokine ligand (CXCL)-1, and CXCL-2 in multilayered sheets was much higher than that in single-layered mixed-cell sheets (single-layered sheets) and multilayered sheets of fibroblasts alone (fibroblast sheets). The supernatant in multilayered sheets enhanced angiogenic potency and fibroblast migration compared with single-layered and fibroblast sheets in an in vitro experiment. The wound healing rate in the multilayered sheet-treated group was higher compared with the no-treatment group (control) at the early stage of healing. Moreover, both vessel lumen area and microvessel density in tissues treated with multilayered sheets were significantly increased compared with tissues in the control group. Conclusion: Multilayered sheets promoted wound healing and microvascular angiogenesis in the skin by supplying growth factors and cytokines. Accordingly, our data suggest that multilayered sheets may be a promising therapeutic material for refractory cutaneous ulcers.

This study’s objective was to evaluate the efficacy of treating cutaneous wounds in Wistar rats using a therapeutic laser alone or in combination with topical application of andiroba oil. Twenty-four Wistar rats were distributed into three groups (T4, T7, and T14) of eight animals. To prepare the wounds, a total of four skin fragments per animal were removed using an 8-mm cutaneous biopsy punch. Each animal was inflicted with four surgical wounds, and each wound was subjected to one treatment. The treatments were as follows: saline solution (control, Cn); laser therapy (L), using a 660-nm laser wavelength and 10-J/cm² energy density; fresh andiroba oil (An); laser therapy followed by topical andiroba oil administration (LAn). All treatments in all animals were conducted for 4- (T4), 7- (T7), and 14- (T14) day periods. Edema and purulent secretion were observed in three animals in the An group, and the appearance of an exuberant crust was also observed in one animal from the same group. The LAn group presented the worst wound healing rate and contraction velocity (p < 0.05). Microscopically, there was no difference between groups regarding the presence of inflammation, necrosis, formation of granulation tissue, fibroplasia, and the presence of types 1 and 3 collagen at different treatment times. It was concluded that laser treatment of cutaneous wounds in conjunction with andiroba oil application did not present benefits in reference to the 0.9% NaCl.

As a result of previous studies, we have established the “Fomitop” gel with extracts from the fungus Fomitopsis officinalis has antibacterial properties against some strains such as Staphylococcus aureus, Micrococcus luteus, Bacillus subtilis, and Enterococcus faecalis. Based on these results, we have conducted this research to identify the “Fomitop” gel has a healing effect on the burn wound. For this purpose, were conducted the comparative analysis of healing effects of the “Fomitop” gel with the standard ointment - silver sulfadiazine cream, on artificial burn wounds created on the back skin of a mouse. Total 27 Balb/c mice were included in the experiment and they are divided into three equivalent groups. In the first treatment, the group was applied to the “Fomitop” gel, the second standard group was applied silver sulfadiazine cream, and the third control group untreated by any ointment. On the 1, 5, 12, 21, and 35th days after wound creation, were taken the histological samples from the wound and near areas of the wound. The wound healing process was evaluated based on histological analysis. The burn wounds of the treatment group of mice (applied “Fomitop” gel) fully healed on the 33rd day of the experiment. While the wound healing rate of the standard group of mice (applied silver sulfadiazine cream) was 92.2% on the same day. And the control group mice wound healing rate was 78% (p<0.05). The results of the histological analysis were confirmed an active regeneration of epithelial cells and wound healing in the treatment group. It was good compared to the standard and control groups. As a result of this study, were determined the “Fomitop” gel application is accelerated the tissue regeneration of burn wounds and so on heals wound in a short time.

Objective. The purpose of this study was to evaluate the wound healing efficacy of oxidized regenerated cellulose (ORC)/collagen dressing and ORC/collagen/silver-ORC dressings compared to standard of care or control in treatment of chronic skin wounds such as diabetic foot ulcers (DFUs), venous leg ulcers (VLUs), and pressure injuries sore ulcers (PISUs). Methods. An electronic search was carried out in four popular databases PubMed, Scopus, Embase, and CENTRAL to identify thirteen included studies, comparing the clinical efficacy of ORC/collagen dressings when compared to control in management of chronic skin wounds, especially DFUs, VLUs, and PISUs, and skin graft donor site wounds. Results. Consolidated data from thirteen comparative clinical studies undertaken for management of DFUs, VLUs, and PISUs showed favorable outcomes towards use of ORC/collagen compared to other traditional and hydrocolloid foam dressings in terms of wound healing rate ( P = 0.02 ) and percentage wound relative reduction ( P = 0.003 ). The time taken to achieve complete wound healing in the included studies did not show any statistical significant difference ( P = 0.24 ). There was no significant difference in adverse events between ORC/collagen-treated group and comparative group ( P = 0.19 ). Conclusion. ORC/collagen wound dressings are beneficial in terms of improved wound healing rate and percentage wound relative reduction compared to already existing traditional standard of care with non-MMP, inhibiting biomaterials such as moistened gauze, autologous growth factors, hydrocolloid foam dressings, or ovine extracellular matrix.
