摘要：Background: This is still a public problem that needs to be solved urgently: chronic and refractory wound healing with long course and complex pathological mechanism. At present, there is still a lack of effective clinical treatment. This study, therefore, aims at exploring moist exposed burn therapy/moist exposed burn ointment (MEBT/MEBO) combined with Zhuang medicine detoxification in the treatment of chronic refractory wound healing. Methodology: 100 SPF Wistar rats were randomly divided into blank control group, model control group, MEBO group, Zhuang medicine group and Combined group, with 20 rats in each group. Open wound model was established in blank control group, and chronic refractory wound model was established in other groups. Black control group and model control group were given food and water freely, MEBO group was given dressing change once a day, Zhuang medicine group was given intragastric administration once a day, and combined group was given dressing change and intragastric administration once a day. The effective rate of wound healing was observed after 12 days of continuous intervention. Conclusion: Skin regeneration medical technique combined with Zhuang medicine poison theory can effectively reduce the symptoms of bleeding and exudation, reduce the area of wound, shorten the healing time of wound, and achieve physiological healing of wound. It has a good effect on chronic refractory wound.

摘要：Burn therapy (MEBT)/moist exposed burn ointment (MEBO) is an effective traditional Chinese medicine method to treat diabetic wound, but the mechanism is unclear. Autophagy has been proved to be closely related with wound healing, so MEBO/MEBT is hypothesized to promote diabetic wound healing by regulating autophagy. To explore the mechanism of moist exposed MEBT/MEBO promoting diabetic wound repair. Eighty male Wistar rats were randomly assigned to control (n = 20) and diabetic group induced by intraperitoneal injection of STZ (n = 60), which were further randomly assigned to MEBO, Kangfuxin and model groups (n = 20 each). All rats underwent full-thickness skin resection in the back. Wound healing was dynamically observed and wound tissues were collected at five time points for pathological examination, autophagosome and the expression of PI3K, Akt and mTOR. The healing time in the control group was the shortest, no statistically significant difference was found between the MEBO and the Kangfuxin group (p = 0.76). The morphology of autophagosomes ranged large to small, which was the most obvious in the MEBO group. The mRNA and protein expression of PI3K, Akt and mTOR in each group reached the peak on Day 5, the levels in the MEBO group were the highest (F = 18.43, 19.97, 15.36, p < 0.05). On Day 11, the expression levels in each group began to decline. In this study, we discussed the molecular mechanism of MEBT/MEBO promoting the repair of diabetic ulcer wounds through autophagy and PI3K-Akt-mTOR signalling pathway, which provides a new way for drug design in the future.

摘要：Objective To introduce a new method of treating facial soft tissue defect by observing the clinical curative effects of traditional Chinese medicine moisture exposed burn ointment in treating facial soft tissue defect. Methods A total of 85 patients with facial soft tissue defects were treated with traditional Chinese medicine moisture exposed burn ointment, and the clinical therapeutic effects were analyzed by observing the wound healing time, scar formation and changes of facial appearance and functions. Results Of the 85 patients, the shortest wound healing time was 12 days and the longest was 72 days; the facial appearance and functions restored to be normal in 74 patients, with good skin elasticity and mild scar formation in the wound area; 11 patients were lost to the follow-up; two patients suffered from the longest wound healing time due to their skin defect of nasal tip and nasal columella and the cartilage defect of nasal wings, and V-shaped defects were left at the edge of the left nostrils after the wound healing, which may be attributed to the ineffectiveness of MEBT/MEBO on cartilage. Conclusion Traditional Chinese medicine moisture exposed burn ointment can realize more satisfying healing effects when applied in the treatment of facial soft tissue defects, including user-friendly operation, no special requirements for medical devices, obviously lower treatment cost, etc., and thus it is an easy-to-operate and effective way for such patients, especially for elderly patients, patients with poor body conditions and patients unbearable to undergo complicated operations.

摘要：This study explored the effects of Moist Exposed Burn Ointment (MEBO) on the healing process of pressure-induced wounds. Using a stage IV pressure ulcer model established in 42 rats, divided equally into a control gel group and an MEBO group, we investigated the efficacy of MEBO through topical application. The control group received Carbomer gel, while the MEBO group was treated with MEBO until complete wound healing. Results showed that MEBO significantly accelerated wound healing compared to the control group. Histological analysis, including hematoxylin and eosin (HE) staining and Masson’s trichrome staining, revealed enhanced epithelialization and collagen deposition in the MEBO group. Furthermore, 16S rRNA sequencing indicated that MEBO reduced microbial diversity at the wound site and reshaped the microbial composition. Notably, The increased abundance of Acinetobacter and Staphylococcus, coupled with a reduction in Pseudomonas, may reflect a shift in the wound microbiome that could be conducive to healing. However, the exact role of these microbial shifts in promoting wound healing requires further investigation, as microbial dynamics in wound environments are complex and context-dependent. These findings suggest that MEBO facilitates wound healing by optimizing the wound microbiome, thereby offering a promising therapeutic approach for managing pressure ulcers.
