摘要：目的体外观察湿润烧伤膏(moist exposed burn ointment,MEBO)对糖尿病大鼠慢性创面纤维细胞生长的影响,探讨MEBO促进糖尿病慢性创面愈合的机制。方法首先建立糖尿病创面大鼠模型,待第11天后分离、培养创面成纤维细胞,经消化、传代至第3代后,随机将细胞分成对照组、MEBO组(1 g/L),采用CCK-8法检测12、24、48、72、96 h细胞增殖情况,采用细胞划痕来观察MEBO对成纤维细胞迁移的影响。结果 48 h起MEBO组各个时间点的OD值均高于对照组(P<0.05或0.001),细胞增殖率在72 h达到高峰;划痕实验检测显示,MEBO组促进成纤维细胞迁移能力比对照组强,差异有统计学意义(P<0.01)。结论 MEBO可促进糖尿病大鼠慢性创面成纤维细胞增殖与迁移能力。

摘要：目的探讨湿润烧伤膏(moist exposed burn ointment,MEBO)对SD大鼠深Ⅱ度烫伤创面微循环的作用机制。方法选取65只SD雄性大鼠,每只大鼠背部建立2个烫伤创面并随机分为MEBO组与对照组,其中MEBO组创面采用MEBO换药治疗,对照组不做任何处理,观察两组创面组织中内皮素-1 (ET-1)、一氧化氮合成酶(NOS)、热休克蛋白70 (HSP70)、CD34及髓过氧化物酶(MPO)的变化情况。结果 (1)大体观,MEBO组创面始终保持湿润状态,新生肉芽组织及上皮组织逐渐生长,至烫伤后第16天创面基本愈合;对照组创面始终干燥坚硬,至烫伤后第16天焦痂完全脱落,大部分创面愈合,创面明显缩小。(2)两组创面愈合率对比,其中烫伤后第4、7、19天,P均> 0. 05,差异无统计学意义;烫伤后第10、13、16天,P均<0. 05,差异具有统计学意义。(3)烫伤后1、6、12、24、48、72、96、120、144 h两组创面组织中ET-1、NOS及HSP70表达水平对比,P均> 0. 05,差异无统计学意义。(4)烫伤后第1、4、7、10、13、16天两组创面组织中MPO表达水平对比,P均> 0. 05,差异无统计学意义。(5)两组创面组织中CD34表达水平对比,其中烫伤后第1、4、10、13、16天对比,P均> 0. 05,差异无统计学意义;烫伤后第7天对比,P <0. 05,差异具有统计学意义。结论MEBO可促进SD大鼠深Ⅱ度烫伤创面的愈合,但与微循环相关介质ET-1、NOS、CD34等并无明显相关性,MEBO促进创面愈合的作用机制仍需进一步深入研究探讨。

摘要：Anal fissure is a common complication of the anorectal region and one of the most reported causes of anal pain. Acute anal fissure can be cured by surgery or medical treatment. There is an increase in the use of topical therapy for the treatment of anal fissures. A common topical drug used is Diltiazem (DTZ), a calcium-channel blocker, which relaxes the anal sphincter and thus promotes healing of the anal fissure. Moist exposed burn ointment (MEBO) is an ointment that is effective for the treatment of burns and wound healing and is becoming popular in the treatment of anal fissures.

摘要：One hundred and thirty-eight (138) patients, with five hundred and sixty-six (566) different burn sites with different degrees, severity and locations, were enrolled to a multicenter clinical trial at 25 study centers. The goal of this trial was to evaluate the efficacy of MEBO (Moist Exposed Burn Ointment) in the treatment of burn wound. Various parameters were studied including: (i) healing time, (ii) need for pain killers, (iii) consumption of i. v. Fluids, (iv) use of systemic antibiotics and (v) aesthetic appearance. There was remarkable decrease in the healing time and most patients either did not need any pain killer or were relieved with only mild analgesics, except in few cases of deep second degree and third degree burns. A decrease in the volume of i. v. fluids needed was also reported. Only 19% of cases developed clinical infection, especially in those who were not treated with MEBO immediately post burn. Even though systemic antibiotic treatment was prophylactically implemented in most cases as a routine measure, 32 cases did not receive any antibiotic prophylaxis with MEBO and yet did not develop any infection. The aesthetic appearance reported was very acceptable. This treatment modality was not associated with any side effects, and patient discomfort during application and change was negligible. Thus, MEBO treatment was associated with excellent and relatively faster healing, low incidence of wound infection, and excellent patient compliance.
