TGF-β1 (transforming growth factor β1) was considered to play a critical role in the forming of hypertrophic scars. Smad, as a kind of signal downstream mediators, can modulate the functions of TGF-β1. Smad7 can regulate TGF-β1/Smad pathway and present negative feedbacks, which prevents fibrosis mediated by TGF-β1. ⋯ Enhanced degradation of Smad7 protein in the fibroblasts of hypertrophic scars was prevented by proteasome inhibitors MG132 / MG115. Furthermore, it was found that TGF-β1 stimulation increased Smad7 protein expression after silencing Smurf2 gene in hypertrophic scar fibroblasts, and enhanced Smad7 degradation was prevented in hypertrophic scar fibroblasts after Smurf2 was silenced. It was implied that ubiquitin degradation mediated by Smurf2 might contribute to decreased Smad7 protein levels following TGF-β1 stimulation in the fibroblasts of hypertrophic scars.

Currently information regarding burn size from referring departments to burn centres varies in accuracy. Inaccurate assessment of burn size can lead to over or under treatment. Photographs of injuries may improve accuracy of assessment. We aimed to assess the accuracy of measuring burn size on a static image by including a standard object in the image. ⋯ Static images tend to overestimate burn size despite the use of a standard object in the image.

The treatment of skin burns is one of the most important challenge in medical science. The aim of this study is evaluation of the efficacy of Artaderm herbal ointment containing the Henna (Lawsonia inermis) extract, Linseed (Linum usitatissimum) oil, and Honey Wax on wound healing in the rat with second-degree burn wounds. The Artaderm ointment had an effective role in controlling burn wound infections due to its antimicrobial and anti-inflammatory properties. ⋯ No scar was observed in rats treated with the Artaderm ointment on the 21st day, while this level of improvement was not observed in other groups at the same time. More than 90% of wounds were healed after on the 14th day in rats treated with Artaderm (94.10 ± 0.18) and Alpha (92.05 ± 0.23) ointments. According to these findings, it can be concluded that Artaderm herbal ointment can be used as a proper alternative for healing of wounds in second-degree burns.

Severe burns are accompanied by an acute and prolonged hypermetabolic response typified by elevated levels of proinflammatory cytokines and acute phase proteins. When persistent, this inflammatory response can result in multi-organ dysfunction and death. Regarded as the standard of care, early removal of devitalised tissue and eschar mitigates this hypermetabolic response. Ascertaining the optimal time point for early excision, which remains controversial, has several clinical implications. ⋯ While it is physiologically important to perform early burn wound excision to mitigate the inflammatory response, delaying excision beyond 24 h for surgical planning, possibly up to 72 h after injury, may be a reasonable approach for certain patient groups.

Persons with severe burns often develop long-term psychosocial difficulties such as posttraumatic stress disorder (PTSD) and depression. Significant appearance changes following burn injury (e.g., scarring and disfigurement) can lead to body image dissatisfaction (BID) that causes psychological problems. Using a two-wave longitudinal design, this study examined the association between burn severity and psychosocial adjustment after burns (symptoms of PTSD and depression), particularly through the mediating role of BID. ⋯ The current findings highlight the importance of BID in the development and maintenance of psychosocial maladjustment long after burn injury.
