摘要：Aim. This study aimed to compare the effect of MEBO versus 0.2% hyaluronic acid gel (Gengigel?) applied to the palatal donor site on postoperative pain reduction and wound healing after free gingival graft harvesting. Methodology. Thirty-nine patients with different mucogingival defects were included in this study for harvesting a free gingival graft (FGG) for soft tissue augmentation. Patients were randomly assigned into three equal groups: group I (MEBO), group II (0.2% HA Gengigel?), and group III (control). Postoperative pain was recorded by using the Visual Analogue Scale (VAS). Analgesic consumption was recorded for 7 days postoperatively. Wound size was measured at baseline and on days 3, 7, 14, and 21. Postoperative healing of the palatal wound was assessed by the VAS score for color match on days 3, 7, 14, 21, and 42. Results. Results of this study showed significant postoperative pain reduction for the three groups; MEBO showed statistically significant less VAS score compared to the other two groups, while HA showed statistically significant less VAS score compared to the control group. Both MEBO and HA showed statistically significant less total analgesic consumption. No statistically significant difference was observed between groups for wound size. MEBO showed statistically significant higher VAS for color match. Conclusions. Both treatment modalities could reduce postoperative pain following harvesting of FGG and improve the palatal wound healing. However, MEBO showed better outcomes in terms of postoperative pain and color match.

摘要：Microskin graft is a technique of skin defect closure using a minimum of STSG donors to cover the large defect. Some considerations were taken, which includes the general status of the patient, donor area morbidity, and patient refusal to act is one of the reasons for the use microskin graft. History STSG failure with previous defect closure and lack of donor area would to bene!t from microskin graft. Case of boy 12 years old with extensive defects in the forearm due to burns. Consideration of the lack of donor area made us deciding to use microskin graft as main option to close the defect. We did one-week post operative evaluation. Epithelialization occurs at day 7, while complete epithelialization occurred at 14th day. Three month during follow-up control, the scar are minimal. We conclude that microskin graft is one technic that can be used in skin defect closure with minimal donor.

摘要：Objective To introduce a new method of treating facial soft tissue defect by observing the clinical curative effects of traditional Chinese medicine moisture exposed burn ointment in treating facial soft tissue defect. Methods A total of 85 patients with facial soft tissue defects were treated with traditional Chinese medicine moisture exposed burn ointment, and the clinical therapeutic effects were analyzed by observing the wound healing time, scar formation and changes of facial appearance and functions. Results Of the 85 patients, the shortest wound healing time was 12 days and the longest was 72 days; the facial appearance and functions restored to be normal in 74 patients, with good skin elasticity and mild scar formation in the wound area; 11 patients were lost to the follow-up; two patients suffered from the longest wound healing time due to their skin defect of nasal tip and nasal columella and the cartilage defect of nasal wings, and V-shaped defects were left at the edge of the left nostrils after the wound healing, which may be attributed to the ineffectiveness of MEBT/MEBO on cartilage. Conclusion Traditional Chinese medicine moisture exposed burn ointment can realize more satisfying healing effects when applied in the treatment of facial soft tissue defects, including user-friendly operation, no special requirements for medical devices, obviously lower treatment cost, etc., and thus it is an easy-to-operate and effective way for such patients, especially for elderly patients, patients with poor body conditions and patients unbearable to undergo complicated operations.

摘要：目的：观察超脉冲CO2点阵激光Active FX、Deep FX治疗兔耳浅表性瘢痕的创面愈合情况并比较湿性创面护理技术和传统外科创面护理技术，创面愈合的差异性。研究CK19、P63在兔耳浅表性瘢痕点阵激光修复中的表达及不同创面护理技术对它们的影响，为临床采用超脉冲CO2点阵激光治疗瘢痕、寻找表皮干细胞参与瘢痕修复的证据。方法:选取新西兰大白兔20只，在兔耳腹侧面制作边长为1.5cm的正方形全层皮肤及软骨膜缺损创面，每只兔耳2个创面，共计80个创面，建立兔耳浅表性瘢痕模型。激光治疗分为两组: UltraPulse CO2Fractional（超脉冲CO2点阵）激光Active FX治疗组和UltraPulse CO2Fractional（超脉冲CO2点阵）激光Deep FX治疗组;激光治疗后创面修复分为两组：传统络合碘治疗方法组和湿润烧伤膏治疗方法组。每天观察创面愈合情况，记录每个创面的愈合时间；收集治疗前、治疗后即刻、1天、4天、7天、14天的瘢痕组织标本作病理组织切片，行HE染色镜下观察，并采用免疫组化检测皮肤干细胞标志分子角蛋白19（cytokeratinsCK19）、转录因子P63的表达，分析超脉冲CO2点阵激光两种不同模式和两种创面修复方法对CK19、P63的影响。结果:1、大体观察：络合碘组Active FX、Deep FX模式治疗后第2～3天创面开始干燥结痂、第9～10天痂皮开始脱落、第14天创面愈合，瘢痕较治疗前平整，颜色变浅；湿润烧伤膏组Active FX模式治疗后创面湿润，第2～3天创面可见散在点状结痂，第5～6天点状痂皮脱落,Deep FX模式治疗后创面未见明显结痂，治疗后第6～7天创面上皮化愈合。点阵激光Active FX模式治疗：络合碘组创面愈合时间为（13.7±0.65）天，湿润烧伤膏组创面愈合时间为（10.4±0.80）天，组间差异有统计学意义（P＜0.05）；点阵激光Deep FX模式治疗：络合碘组创面愈合时间为（9.4±0.28）天，湿润烧伤膏组创面愈合时间为（7.5±0.62）天，组间差异有统计学意义（P＜0.05）；Active FX模式和Deep FX模式治疗创面愈合时间对比，...
