摘要：目的探讨湿润烧伤膏对糖尿病皮肤溃疡小鼠的创面愈合及抗氧化酶中超氧化物歧化酶(superoxide dismutase,SOD)、谷胱甘肽过氧化物酶(gbutathione peroxidase,GSH-px)表达水平的影响。方法自2020年12月至2021年5月,北部战区总医院烧伤整形科选取40只健康小鼠,其中30只小鼠的腹腔内注射链脲佐菌素,诱导成糖尿病小鼠模型,然后将所有小鼠的背部制作溃疡创面。分组:湿润烧伤膏组(实验组)、康复新液对照组(阳性对照组)、模型对照组、空白对照组(健康小鼠),每组10只小鼠。对实验组和阳性对照组的创面分别给予湿润烧伤膏和康复新液进行外用处理,1次/d,连续处理14%d;模型对照组和空白对照组不予处理。2周后,观察小鼠创面的愈合情况及病理变化,采集小鼠球后静脉血,检测血清中抗氧化酶SOD、GSH-PX的表达情况,并比较四组间的差异。结果用药2周后,实验组、阳性对照组创面愈合率明显优于模型对照组,其差异具有统计学意义(P<0.01)。实验组、阳性对照组、模型对照组中SOD、GSH-px的表达与空白对照组比较降低,其差异具有统计学意义(P<0.01),实验组、阳性对照组中SOD、GSH-px的表达与模型对照组比较升高,其差异具有统计学意义(P<0.01)。HE染色结果显示,四组中的成纤维细胞、胶原纤维的再生及排列情况有明显差异。结论湿润烧伤膏处理糖尿病小鼠的溃疡创面后,抗氧化酶SOD、GSH-PX的表达明显升高,具有抗氧化作用。研究表明湿润烧伤膏可促进创面愈合。

摘要：Facial burns vary from relatively minor insults to severe debilitating injuries. Sustaining a burn injury is often a psychological trauma for the victim and is especially menacing when the face and neck are involved. This study was carried out on 60 patients with superficial dermal burns to the face admitted to the Burn Unit of Tanta University Hospital, Egypt, from September 2007 to July 2008. The patients were allocated randomly to one of three groups, each of which was treated with one of the following: sodium carboxymethyl-cellulose silver (Aquacel Ag?), MEBO? (moist exposed burn ointment), or saline-soaked dressing. We found that patients managed with MEBO? had less pain and itching and easier movement than those managed with Aquacel Ag?, while the Aquacel Ag? group required a shorter duration of time for healing, without any bad odour, than the MEBO? group. Quality of healing and patient satisfaction were nearly equal as regards MEBO? and Aquacel Ag?. Saline-soaked dressings were least satisfactory - they caused the most pain and itching, limited the patients' movements the most, needed the longest time for healing, and gave patients the least satisfaction. It was concluded that MEBO? was an excellent choice for management of facial burns owing to its soothing effect, ease of patient movement, easy handling, and good healing properties. Aquacel Ag? was found to be comparable to MEBO? and is specially recommended when frequent dressings cause difficulties for the patients or when they cannot accept a bad odour; saline-soaked dressings are not recommended for the management of facial burns because of the pain they cause, itching, limitation of patient movement, and delayed healing.
