摘要：目的 探讨湿润烧伤膏(MEBO)联合微粒皮种植对糖尿病足创面组织中血管内皮生长因子(VEGF)、表皮生长因子(EGF)表达水平的影响。方法 给予2018年1月至2020年12月广州医科大学附属第五医院收治的38例Wagner 2～3级糖尿病足患者创面行MEBO联合微粒皮种植治疗,观察创面愈合情况,并对比治疗前与治疗第7、14天创面面积以及创面组织中VEGF、EGF含量。结果 治疗2个月后,33例患者创面完全愈合、5例患者创面明显缩小。治疗过程中,38例患者创面组织中VEGF及EGF含量均呈逐渐升高趋势,其中各时间点创面组织中VEGF含量对比差异均具有统计学意义(q=10.310、23.280、12.970,P均<0.001);EGF含量除治疗前与治疗第7天对比,差异无统计学意义(q=1.797,P=0.945)外,其余各时间点对比,差异均具有统计学意义(q=12.040、10.240,P均<0.001)。Pearson相关系数分析结果显示,创面组织中VEGF、EGF含量与创面面积无明显相关性(r=0. 181、0.205,P=0.833、0.094)。结论MEBO联合微粒皮种植促进糖尿病足创面愈合的机制可能与MEBO能够上调创面组织中VEGF、EGF的表达水平有关。

摘要：体表慢性难愈合创面(俗称溃疡)是由一系列创伤和疾病所致,这类创面具有病程长、对外观影响大以及并发症多等特点。中医外治溃疡历史悠久,近年来,我们在临床上应用MEBT/MEBO治疗多种慢性难愈合皮肤创面,取得了较好的疗效[1]。本实验进一步探讨MEBT/MEBO对皮肤溃疡局部血管内皮细胞粗面内质网结构的影响,以期可以从不同侧面揭示

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.
