摘要:目的探讨严重烧伤(重度和特重度)急性渗出期,采用烧伤湿性医疗技术(MEBT/MEBO)防治早期休克的临床效果。方法总结5年来,我院对56例严重烧伤急性渗出期,采用MEBT/MEBO治疗的病历资料,分析他们的休克发生率和液体实际输入量,推导出他们的补液计算参数。结果 56例患者均平稳度过休克期,未发现休克病例,心、肾功能正常;第1个24h每1%烧伤面积计算补液参数为0.9~1.25,第2个24h为0.5~0.65。结论严重烧伤急性渗出期采用MEBT/MEBO治疗,可有效防治早期休克,减少输液量。
摘要:Objective: To investigate the mechanism of the effect of Moist Exposed Burn Therapy (MEBT) and Moist Exposed Burn Ointment (MEBO) on the spontaneous repair and healing of superficial third degree burn wound involving fatty layer. Method: A series of skin tissue samples were taken from deep burn wounds of 2 cases. Immunocytochemistry method, biotin-avidin DCS system, and indirect immunofluorescence technique were applied. Mouse anti-human keratin type 19 monoclonal antibody was used to detect regenerative epidermal stem cells in wound tissues. Results: Epidermal regenerative stem cells emerged at 24 hours post burn, and the number of epidermal regenerative stem cell increased on day 4 post burn. On days 7 and 14 post burn, the number of epidermal stem cells increased to the peak level. On days 21 and 28 post burn, it decreased and disappeared gradually as burn wound progressed to healing. Conclusion: MEBT/MEBO has the effect of promoting the activation and proliferation of epidermal regenerative stem cells in ...
摘要:目的:慢性难愈合创面是临床中常见的病种之一,但在治疗上缺乏有效的手段干预,越来越多的研究将慢性难愈合创面的治疗靶向转变为促进创面血管新生,探究MEBT/MEBO在促进血管新生过程的作用机制,为临床推广和应用MEBT/MEBO治疗慢性难愈合创面提供理论依据和参考价值;方法:应用付小兵及沈道修相结合的造模方法,分组为空白组、急性创面组、慢性难愈合创面组、贝复济组、MEBT/MEBO组,采用Image J软件、Western Blot、RT-PCR等方法,从宏观到微观观察PTEN-Akt-VEGF信号通路在各组中的动态变化;结果:MEBT/MEBO能够通过调控PTEN-Akt-VEGF信号通路,促进VEGF表达及其mRNA的转录,促进创面血管新生,提高创面愈合率。结论:(1)血管新生是创面修复的一个重要过程,上调VEGF的表达可加速血管新生,并以此促进创面愈合;(2)MEBT/MEBO在慢性难愈合创面的治疗中是安全、高效的治疗手段,可通过调控PTEN-Akt-VEGF信号通路,促进创面血管新生,达到创面愈合的效果。
摘要:烧伤湿性医疗技术(MEBT/MEBO)现已形成了较为系统的皮肤原位再生学术体系,由于PBL教学法强调培养学生分析问题和解决问题的能力,强调基础学科与临床医学的密切联系,通过尝试在七年制医学生外科学临床教学中引入PBL(Problem-based learning teaching method)教学法,以期达到提高学生的临床综合分析能力和临床操作技能之目的。作者从MEBT/MEBO教学目标、问题的设计及小组讨论方案各方面提出了具体需要解决的问题,对PBL应用于MEBT/MEBO教学就必要性、优越性、缺陷性及存在的问题等方面进行思考和分析,并提出了其发展展望。
