摘要：BACKGROUND Aplasia cutis congenita (ACC) in newborns is a condition in which congenital defects or hypoplasia is present in part of the epidermis, dermis and even subcutaneous tissue (including muscle and bones). First reported by Cordon in 1767, ACC is a rare disease with a low incidence of 1/100000 to 3/10000. Currently, there are 500 cases reported worldwide. ACC can be accompanied by other malformations. The onset mechanism of the disease remains unknown but is thought to be correlated to factors such as genetics, narrow uterus, foetal skin and amniotic membrane adhesion, use of teratogenic drugs in early pregnancy and viral infection. CASE SUMMARY In August 2018, we treated a newborn with ACC on the left lower limbs using a combination of ionic silver dressing and moist exposed burn ointment (MEBO) and achieved a satisfactory treatment outcome. The skin defects were observed on the external genitals and on areas from the left foot to 3/4 of the upper left side. Subcutaneous tissue and blood vessels were observed in the regions with skin defects. The following treatments were provided. First, the wound was rinsed with 0.9% sodium chloride solution followed by disinfection with povidone-iodine twice. And then MEBO was applied to the wound at a thickness of approximately 1 mm. After applying ionic silver dressing, the wound was covered with sterile gauze. The wound dressing was replaced every 2-3 d. At the 4-mo follow-up, the treatment outcome was satisfactory. There was minimal scar tissue formation, and limb function was not impaired. CONCLUSION The combination of ionic silver dressing and MEBO to ACC is helpful.

摘要：目的 探讨皮肤再生医疗技术(MEBT/MEBO)对大鼠慢性难愈合创面组织内核转录因子红系2相关因子2(Nrf2)/血红素氧合酶1(HO-1)/醌氧化还原酶1(NQO1)信号通路的影响。方法 选取90只SPF级Wistar雄性大鼠适应性饲养1周后，采用随机数表法将其随机分为空白组、对照组、模型组、MEBO组和贝复新组，每组18只。其中空白组大鼠只做备皮处理，对照组大鼠建立急性创面模型，模型组、MEBO组和贝复新组大鼠建立慢性难愈合创面模型。模型建立后，空白组大鼠备皮处皮肤及对照组、模型组大鼠创面予以生理盐水纱布换药处理，MEBO组大鼠创面予以湿润烧伤膏(MEBO)药纱换药处理，贝复新组大鼠创面予以重组牛碱性成纤维细胞生长因子凝胶药纱换药处理，对比观察各组大鼠创面愈合率、组织病理学变化情况以及皮肤/创面组织内丙二醛(MDA)、超氧化物歧化酶(SOD)及Nrf2、HO-1、NQO1蛋白与HO-1、NQO1 mRNA表达水平。结果 干预第3天，各组大鼠创面愈合率尤以对照组最高、贝复新组次之(P均<0.05);干预第7、14天，各组大鼠创面愈合率尤以MEBO组最高、贝复新组次之(P均<0.05)。HE染色结果显示，干预第3、7、14天，对照组、MEBO组和贝复新组大鼠创面组织内坏死细胞及炎性细胞逐渐减少，成纤维细胞与毛细血管逐渐增多，而模型组大鼠创面组织内坏死细胞和炎性细胞减少不明显；Masson染色结果显示，干预第3、7、14天，对照组、MEBO组和贝复新组大鼠创面组织内胶原纤维由细少且紊乱逐渐趋于粗大且平整，而模型组大鼠创面组织内胶原纤维虽逐渐增粗、增多，但排列仍较紊乱。干预第7天，对照组、MEBO组和贝复新组大鼠创面组织内MDA表达水平均明显低于模型组(P均<0.05);干预第3、7天，对照组、MEBO组和贝复新组大鼠创面组织内SOD表达水平均明显高于模型组(P均<0.05)。干预第3、7天，MEBO组和贝复新组大鼠创面组织内Nrf2、HO-1、NQO1蛋白以及HO-1、NQO1 mRNA表达水平均明显高于空白组、对照组和模型组(P均<0.05),且干预第7天，MEBO组大鼠创面组织内Nrf2、HO-1蛋白以及HO-1 mRNA表达水平均明显低于贝复新组(P均<0.05)。结论 MEBT/MEBO可能能够通过激活Nrf2/HO-1/NQO1信号通路减轻大鼠慢性难愈合创面氧化应激损伤，促进创面再生修复。

摘要：Burn injuries are associated with anatomically within physiologically infections and biochemically within immunologically defect in hepatic functions during direct action on locally and systematic role of blood elements and liver enzymes. These defects represented the cellular response due to burn injuries. Aim of study: to assess the treatment and antioxidant action of MEBO ointment in medical therapy ,such as burn therapy. Methods: The study was performed by 66 burn patents(male) received treatment with ointment MEBO(100g)twice daily for two weeks and all patients have thickness burn injury, age ranged(15-65years for all subjects) and 50 men healthy control subjects ,So one day post burn samples were collected for hematological &biochemical parameters in kirkuk city at Azaadi hospital ,and this study done from march to December 2019 . Results: Leukocytes count (WBC), Neutrophil, lymphocyte,) and erythrocyte sedimentation rate ( ESR) were increased, while red blood cells count (RBC), hemoglobin (HB) were decreased after burn injury. Creatinine and potassium element are increased significantly, while Sodium element was decreased and significantly increased in the liver enzyme and glutathione after treatment when MDA significantly decreased .Conclusion: This study concluded that blood parameters and liver functions were altered due to burn injuries and these modulations attributable to the lipid peroxidation(MDA), while the liver enzyme signaling of hepatic activity for glutathione synthesis for curbing the free radicals after treatment by MEBO ointment ,this productive mechanism may be new defect liver mechanism for burn injury.
