摘要：Conventional management of partial-thickness burn wounds includes the use of paraffin gauze dressing, frequently with topical silver-based antibacterial creams. Some creams form an overlying slough that renders wound assessment difficult and are painful upon application. An alternative to conventional management, moist exposed burn ointment (MEBO), has been proposed as a topical agent that may accelerate wound healing and have antibacterial and analgesic properties. One hundred fifteen patients with partial-thickness burns were randomly assigned to conventional (n = 58) or MEBO treatment (n = 57). A verbal numerical rating score of pain was made in the morning, after burn dressing, and some 8 hours later. Patient pain profiles were summarized by locally weighted regression smoothing technique curves and the difference between treatments estimated using multilevel regression techniques. Mean verbal numerical rating scale pain levels (cm) in week 1 for all patients were highest at 3.2 for the after dressing assessment, lowest in the evening at 2.6, and intermediate in the morning at 3.0. This pattern continued at similar levels in week 2 and then declined by a mean of 0.5 in all groups in week 3. There was little evidence to suggest a difference in pain levels by treatment group with the exception of the postdressing pain levels in the first week when those receiving MEBO had a mean level of 0.7 cm (95% confidence interval, 0.2 to 1.1) lower than those on conventional therapy. MEBO appeared to bring greater pain relief for the postdressing assessment during the first week after burns. This initial relief, together with comparable pain levels experienced on other occasions, indicates that MEBO could be an alternative to conventional burns management.

摘要：Hypertrophic scars, resulting from alterations in the normal processes of cutaneous wound healing, are characterized by proliferation of dermal tissue with excessive deposition of fibroblast-derived extracellular matrix proteins, especially collagen, over long periods, and by persistent inflammation and fibrosis. Hypertrophic scars are among the most common and frustrating problems after injury. As current aesthetic surgical techniques become more standardized and results more predictable, a fine scar may be the demarcating line between acceptable and unacceptable aesthetic results. However, hypertrophic scars remain notoriously difficult to eradicate because of the high recurrence rates and the incidence of side effects associated with available treatment methods. This review explores the various treatment methods for hypertrophic scarring described in the literature including evidence-based therapies, standard practices, and emerging methods, attempting to distinguish those with clearly proven efficiency from anecdotal reports about therapies of doubtful benefits while trying to differentiate between prophylactic measures and actual treatment methods. Unfortunately, the distinction between hypertrophic scar treatments and keloid treatments is not obvious in most reports, making it difficult to assess the efficacy of hypertrophic scar treatment.

摘要：Purpose: To investigate the bioactive components and mechanism of action of moist exposed burn ointment (MEBO) for treatment of diabetic foot ulcers using network pharmacology (NP) and molecular docking technology Methods: Through pharmacology database of traditional Chinese medicine (TCM) systems (TCMSP), analysis platform and symptom mapping (SymMap) database, the bioactive components of MEBO were screened for and protein binding to bioactive components was predicted. Proteins related to Diabetic foot ulcer (DFU) were collected from GeneCards, OMIM, PharmGkb and TTD disease databases. With R language software, the binding proteins of bioactive components of MEBO intersected with the proteins related to occurrence of DFU. Proteins of DFU linked to treatment with MEBO were subjected to analysis using gene ontology (GO) and KEGG with R language software. AutoDock and PyMOL software were employed to dock active components of MEBO and major proteins of DFU. Targeted binding potential of bioactive compounds in MEBO to core proteins of DFU was analyzed. Results: One hundred and five (105) bioactive ingredients and 246 likely therapeutic proteins were obtained. Proteins were mainly involved in biological processes in wound healing, oxidative stress, and lipopolysaccharide. The enriched signaling pathway focused on lipid metabolism and the process of atherosclerosis which involved PI3K and Akt, advanced glycation end-products (AGE)-receptor (RAGE) and mitogen-activated protein kinase (MAPK). The absolute values of these proteins were screened out with a docking score greater than 5 kcal/mol. Conclusion: The biological effects of MEBO are related to multiple proteins and multiple signaling pathways. Therefore, healing effect of MEBO on DFU occurs via multiple pathways. The biological characteristics of MEBO need to be fully elucidated in further studies.

摘要：Moist exposed burn ointment (MEBO) is becoming increasingly popular in China as it shortens wound?healing time and reduces scar formation. However, its exact mechanism in mediating the wound?healing process is not yet clear. In the present study a total of 90?healthy adult male Wistar rats of specific-pathogen-free grade were divided equally into a control group, wound group, MEBO group, recombinant bovine basic fibroblast growth factor (rb?bFGF) group and sham operation group. Wound healing was observed from the extracted granulation tissues and recorded at three time points on 3, 7 and 14?days. Different levels of tumor necrosis factor?α (TNF?α) and interleukin?6 (IL?6) in tissue homogenate were detected using ELISA. Western blot analysis and quantitative PCR were used to detect the expression of nerve growth factor (NGF), substance P (SP) as?well?as tyrosine kinase?A (TrkA) receptor protein and the corresponding mRNA levels in granulation tissue. It was observed that the wound healing progressed faster in the MEBO and rb?bFGF groups compared with the wound group (P<0.01). TNF?α and IL?6 had an upward?downward trend at three time points, with the wound group demonstrating the most obvious increase (P<0.01). NGF and SP mRNA and protein levels in granulation tissue in MEBO, rb?bFGF and sham operation groups reached their highest levels on day?7 and then decreased on day?14. The expression level of TrkA was also measured simultaneously and its expression pattern was similar to that of NGF and SP. These results suggested that MEBO may promote nerve repair and accelerate wound healing through mediating the expression levels of NGF and SP, as?well?as TrkA.
