皮肤再生医疗技术在供皮区的临床应用

目的 :探寻一种更利于供皮区创面修复的方法。方法 :应用皮肤再生医疗技术 (MEBT/MEBO)处理植皮手术供皮区创面 6 7例 (A组 ) ,与传统凡士林纱布处理供皮区 71例 (B组 ) ,在术后疼痛、愈合时间、愈合质量上进行比较分析。结果 :皮肤再生医疗技术治疗组在愈合时间、愈合质量与凡士林治疗组比较均有显著性差异 (P <0 0 1)。结论 :皮肤再生医疗技术能实现薄皮片和中厚皮片供皮区创面皮肤生理性再生修复、提高皮肤愈合质量、减少瘢痕增生等作用。

MEBT/MEBO在浅Ⅲ度烧伤创面愈合过程中的组织学观察

目的 :从组织学角度验证MEBT/MEBO治疗浅Ⅲ度烧伤创面 ,能够达到生理性再生修复 ,及其不同时期组织学变化。方法 :分别于MEBT/MEBO治疗后 1天、 3天、 7天、 2 0天、及 30～ 4 0天创面愈合后取标本 ,常规光镜、电镜制样 ,进行光镜、透射电镜对创面各期内进行组织形态观察。结果 :浅Ⅲ度烧伤创面经MEBT/MEBO正规治疗 ,历经早期真皮组织变性坏死 ,中后期棘细胞、纤维母细胞、毛细血管增生等阶段 ,最后再生修复的上皮组织形态可以恢复正常。结论 :MEBT/MEBO治疗浅Ⅲ度烧伤创面再生修复属完全性生理再生 ,其愈合后创面组织形态可以恢复正常。

糖尿病足溃疡治疗现况的报告

目前,糖尿病足溃疡的治疗是一个世界性难题,医学界普遍使用的治疗方法有:1)常规辅料:凡士林、生理盐水、碘伏、银辅料等;2)新型辅料(AMWT):藻酸盐、水凝胶、硅胶泡沫等;3)物理治疗:负压引流、高压氧等;4)生物辅料:生长因子、人工皮片等;5)手术治疗:植皮、皮瓣覆盖等。但是,这些方法存在以下问题:没有确切疗效,创面容易感染,截肢率高,价格昂贵,创面愈合后皮肤耐磨性能差等如今,皮肤原位再生复原技术(MEBT/MEBO)在治疗糖尿病足溃疡方面实现了突破性的进展,该技术通过为溃疡创面提供生理性湿润环境,无损伤性地排除液化坏死组织,持续供给组织器官原位再生复原所需的再生营养物质,实现了糖尿病足溃疡的生理性再生复原。而且这种方法疗效确切、操作简单、治疗费用低。下图是MEBT/MEBO与其它方法治疗糖尿病足溃疡效果的对比病例。报告的相关内容,请浏览本刊所附DVD。

Expression patterns and action analysis of genes associated with physiological responses during rat liver regeneration:Innate immune response

AIM： To study the relationship between innate immune response and liver regeneration （LR） at transcriptional level.METHODS： Genes associated with innate immunity response were obtained by collecting the data from databases and retrieving articles, Gene expression changes in rat regenerating liver were detected by rat genome 230 2.0 array.RESULTS： A total of 85 genes were found to be associated with LR. The initially and totally expressed number of genes at the phases of initiation [0.5-4 h after partial hepatectomy （PH）], transition from GO to G1 （4-6 h after PH）, cell proliferation （6-66 h after PH）, cell differentiation and structure-function reconstruction （66-168 h after PH） was 36, 9, 47, 4 and 36, 26, 78, 50, respectively, illustrating that the associated genes were mainly triggered at the initial phase of LR and worked at different phases. According to their expression similarity, these genes were classified into 5 types： 41 up-regulated, 4 predominantly up-regulated, 26 downregulated, 6 predominantly down-regulated, and 8 approximately up/down-regulated genes, respectively. The expression of these genes was up-regulated 350 times and down-regulated 129 times respectively, demonstrating that the expression of most genes was enhanced while the expression of a small number of genes was decreased during LR. Their time relevance was classified into 14 groups, showing that the cellular physiological and biochemical activities dudng LR were staggered. According to the gene expression patterns,they were classified into 28 types, indicating that the cellular physiological and biochemical activities were diverse and complicated during LR. CONCLUSION： Congenital cellular immunity is enhanced mainly in the forepart, prophase and anaphase of LR while congenital molecular immunity is increased dominantly in the forepart and anaphase of LR. A total of 85 genes associated with LR play an important role in innate immunity.

环钻环切法治疗复杂性创伤性文身的效果观察

目的探讨一种简便、安全、有效的治疗复杂性创伤性文身的方法,评估远期疗效。方法2013年10月至2017年6月,解放军第960医院及连云港市第一人民医院烧伤整形科选择复杂性创伤性文身患者8例,男5例,女3例;年龄18~42岁,平均29岁。在局部肿胀麻醉下经环钻钻取皮肤全层创伤性文身,留置创面自然愈合,创面外敷生肌育肤膏保湿促进伤口愈合,多次换药至创面愈合。结果8例患者全部获得成功,未出现术中和术后并发症。1年后随访,均获得满意效果,无明显瘢痕形成。结论环钻环切法治疗创伤性文身是一种操作简便、创伤轻微、并发症少、经济安全、效果较好的方法,尤其适合面部复杂创伤性文身,值得临床应用。
