摘要：The present study aimed to investigate the expression and predictive value of serum hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) in patients with burns following treatment. A total of 84 patients with burns treated in Jinan City People's Hospital (Jinan, China) between June 2015 and August 2017 were selected and their clinical information was collected. The expression levels of HIF-1α and VEGF before and after treatment were detected via ELISA, and HIF-1α and VEGF levels in patients with effective and ineffective treatment were compared. The predictive values of HIF-1α and VEGF in clinical efficacy were determined using receiver operating characteristic (ROC) curves, and independent risk factors affecting treatment inefficacy were analyzed via multivariate logistic regression. It was revealed that HIF-1α decreased significantly (P<0.05) while VEGF significantly increased in patients after treatment. Patients with effective treatment presented significantly lower HIF-1α levels and higher VEGF levels compared with those with ineffective treatment. The ROC curve indicated that the area under the curve (AUC) of HIF-1α for treatment efficacy was 0.795, the 95% CI was 0.666-0.924, the specificity and sensitivity were 68.75 and 80.88%, respectively, and the Youden index was 49.63%. For VEGF, the AUC, 95% CI, specificity, sensitivity and Youden index were 0.826, 0.725-0.928, 68.75, 82.35 and 51.10% respectively. Moreover, under the joint detection of HIF-1α and VEGF, the AUC was 0.847, 95% CI was 0.746-0.947, specificity and sensitivity were 87.50 and 66.18%, respectively, with a Youden index of 53.68%. Multivariate analysis demonstrated that higher HIF-1α level, lower VEGF level and higher burn degree before treatment were independent risk factors for treatment inefficacy. HIF-1α levels decreased and VEGF levels increased in burn patients after treatment. HIF-1α and VEGF before treatment may therefore serve as predictors for treatment efficacy.

摘要：Objective: To verify the moisture maintaining effect of moist exposed bum ointment (MEBO) in treating burn wound. Methods: Rabbit model with Ⅱdegree burn wound was used in this study. Observations were conducted at 0 (before burn), 0. 5, 6, 24, 48, 72, and 168 hours postburn. The data of wound water evaporation, wound appearance and pathological changes of the wounds were compared with that Of the bum wounds treated with Vaseline or conventional dry exposed therapy. Results: It was found that wounds treated with MEBO had water evaporation close to that of normal skin and was significantly less than that of the wounds treated with dry exposed therapy (P<0. 01). MEBO did not obstruct water evaporation from wound as Vaseline did (P<0.01). Wounds treated with MEBO had good permeability and adequate drainage. Conclusion: MEBO provided the wounds with a physiological moist environment.

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：CONTEXT: Moist exposed burn ointment (MEBO), from China, has been said to revolutionize burn management. OBJECTIVE: Our study was conducted to compare MEBO with conventional management (C) with respect to the rate of wound healing, antibacterial and analgesic effect, and hospital costs. DESIGN: This is a prospective, randomized, controlled clinical trial conducted between 1 March 1997 and 24 October 1998. SETTING: The trial was conducted in a specialized burn facility located in a tertiary referral hospital in a developed and industrialized island-state in Southeast Asia. PATIENTS: We randomly assigned 115 consecutive patients between the ages of 12 and 80 who had partial-thickness thermal burns covering less than 40% of body surface area (BSA) to receive either MEBO or C. Fifty-seven patients were assigned to MEBO and 58 patients to C. The latter group received twice-daily dressing changes; MEBO patients received MEBO every 4 hours. MAIN OUTCOME MEASURES: Patients were hospitalized until 75% BSA had healed. BSA was determined by visual inspection and charted on Lund and Browder charts regularly. Wound healing rate, bacterial infection rate, pain score, and hospitalization costs were recorded. RESULTS: The median time to 75% healing was 17.0 and 20.0 days with MEBO and C, respectively (HR = 0.67, 95% CI = 0.41-1.11, P =.11), suggesting similar efficacy between the 2 modalities. Bacterial infection rates were similar between the 2 groups (HR = 1.10, 95% CI = 0.59-2.03, P =.76). MEBO imparted a greater analgesic effect in the first 5 days of therapy and reduced hospital costs by 8%. CONCLUSIONS: MEBO is as effective as conventional management but is not the panacea for all burn wounds. The use of MEBO eases the management of face and neck burns and facilitates early institution of occupational therapy in hand burns. It confers better pain relief such that fewer opiates are used during the first 5 days after burn injury.
