Abstract
OBJECTIVE To prove the effectiveness of the low-intensity laser radiation application in the treatment of wounds of different origin. MATERIAL AND METHODS The clinical study involved 110 persons, divided into 55 subjects in both the study and control groups. The patients of the study group were exposed to the long-wave short-pulse neodymium laser immediately and within 35 days after interventions with a skin incision using it, in a way that wound treated with laser received low-level laser therapy. The control group patients' wounds were treated with standard methods by the means of topical drugs corresponding to the clinical manifestations of the wound process in each particular case. The study was carried out in the hospital of the department of maxillofacial and plastic surgery of the dental complex of the «Russian University of Medicine» from 2019 to 2022, and further conservative treatment was conducted in the department of dermatology and cosmetology of the University Hospital of the Medical Graduate School (Institute) of the RSSU. All wounds were classified into three groups for the convenience of systematization and formation of a generalized treatment protocol for postoperative surgical wounds. RESULTS The objectivity and optimality of the chosen by us actions were confirmed in the conducted work. The formed scars were visually assessed on the POSAS scale at the end of the treatment by patients and 4 independent doctors, as well as each scar was visually assessed by four independent doctors and patients. At the end of the study we formed and proposed an algorithm for the treatment of surgical wounds of various origins. The parameters of the Aerolase Neo Light Pod neodymium laser for the treatment of patients with different types of skin wounds were clinically determined. Experimentally proven properties of the Aerolase Neo Light Pod neodymium laser on accelerating the healing process of surgical wounds through photobiomodulation mechanism support their regeneration with the formation of negligible normotrophic scars, as well as reduce the length of patients' treatment in surgical hospitals, as compared to patients receiving standard external drugs.

Abstract
Hypertrophic scar (HS) is an abnormal fibrous hyperplasia of the skin caused by excessive tissue repair in response to skin burns and trauma, which restricts physical function and impairs patients' quality of life. Numerous studies have shown that pressure garment therapy (PGT) is an effective treatment for preventing hypertrophic scars. Herein, we found that mechanical stress stimulates the neuropilin 1 (NRP1) expression through screening GSE165027, GSE137210, and GSE120194 from Gene Expression Omnibus (GEO) database and bioinformatics analysis. We verified this stimulation in the human hypertrophic scar, pressure culture cell model, and rat tail-scar model. Mechanical compression increased LATS1 and pYAP enrichment, thus repressing the expression of YAP. Functionally, the knockdown of NRP1 promoted the expression of LATS1, thus decreasing the expression of YAP and inhibiting endothelial cell proliferation. Furthermore, co-immunoprecipitation analysis confirmed that NRP1 binds to YAP, and mechanical compression disrupted this binding, which resulted in the promotion of YAP relocation to nuclear. In conclusion, our results indicated that NRP1 transduces mechanical force inhibition by inhibiting YAP expression. Mechanical pressure can release YAP bound to NRP1, which explains the phenomenon that mechanical stress increases YAP in the nucleus. Strategies targeting NRP1 may promote compression therapy with optimal and comfortable pressures.

Abstract
Wound healing is an essential process to restore tissue integrity after trauma. Large skin wounds such as burns often heal with hypertrophic scarring and contractures, resulting in disfigurements and reduced joint mobility. Such adverse healing outcomes are less common in the oral mucosa, which generally heals faster compared to skin. Several studies have identified differences between oral and skin wound healing. Most of these studies however focus only on a single stage of wound healing or a single cell type. The aim of this review is to provide an extensive overview of wound healing in skin versus oral mucosa during all stages of wound healing and including all cell types and molecules involved in the process and also taking into account environmental specific factors such as exposure to saliva and the microbiome. Next to intrinsic properties of resident cells and differential expression of cytokines and growth factors, multiple external factors have been identified that contribute to oral wound healing. It can be concluded that faster wound closure, the presence of saliva, a more rapid immune response, and increased extracellular matrix remodeling all contribute to the superior wound healing and reduced scar formation in oral mucosa, compared to skin.

Abstract
Unpredictable hypertrophic scarring (HS) occurs after approximately 35% of all surgical procedures and causes significant physical and psychological complaints. Parallel to the need to understanding the mechanisms underlying HS formation, a prognostic tool is needed. The objective was to determine whether (systemic) immunological differences exist between patients who develop HS and those who develop normotrophic scars (NS) and to assess whether those differences can be used to identify patients prone to developing HS. A prospective cohort study with NS and HS groups in which (a) cytokine release by peripheral blood mononuclear cells (PBMC) and (b) the irritation threshold (IT) after an irritant (sodium lauryl sulphate) patch test was evaluated. Univariate regression analysis of PBMC cytokine secretion showed that low MCP-1, IL-8, IL-18 and IL-23 levels have a strong correlation with HS (P < .010-0.004; AUC = 0.790-0.883). Notably, combinations of two or three cytokines (TNF-a, MCP-1 and IL-23; AUC: 0.942, Nagelkerke R2 : 0.727) showed an improved AUC indicating a better correlation with HS than single cytokine analysis. These combination models produce good prognostic results over a broad probability range (sensitivity: 93.8%, specificity 86.7%, accuracy 90,25% between probability 0.3 and 0.7). Furthermore, the HS group had a lower IT than the NS group and an accuracy of 68%. In conclusion, very fundamental immunological differences exist between individuals who develop HS and those who do not, whereas the cytokine assay forms the basis of a predictive prognostic test for HS formation, the less invasive, easily performed irritant skin patch test is more accessible for daily practice.
