目的

初步探讨CTLA4Ig基因转染猪皮复合去表皮真皮组织匀浆治疗深度烧伤创面的临床效果。

方法

回顾性分析2023年 6月至 2025年 6月东莞市厚街医院烧伤与创面修复科收治符合入选标准的深度烧伤患者 28例,其中男 22例,女 6例,年龄 21~67岁,平均(44.61±12.29)岁。按照治疗方案将患者分为观察组(15例)与对照组(13例)。观察组采用自体去表皮真皮组织匀浆与 CTLA4Ig 基因转染猪皮联合移植修复烧伤创面,对照组采用单纯 CTLA4Ig 基因转染猪皮移植修复烧伤创面。比较 2 组创面愈合时间、术后炎症因子水平及瘢痕增生情况,采用温哥华瘢痕量表(VSS)评估瘢痕质量,对瘢痕的色泽、厚度、血管分布、柔软度等进行评分并计算总分;记录治疗期间不良反应发生情况。

结果

观察组创面完全愈合时间显著短于对照组[(20.07±2.49)d比(26.92±6.49)d,P<0.001];术后1 d、7 d观察组白细胞介素-6水平均低于对照组(P均<0.05);术后3个月,观察组VSS评分低于对照组 [(4.53±1.06)分比(5.62±1.50)分,P<0.05)]。

结论

去表皮真皮组织匀浆结合 CTLA4Ig 基因转染猪皮移植修复深度烧伤创面,可显著缩短创面愈合时间,减轻术后炎症反应,并有效改善瘢痕修复质量,为深度烧伤创面的治疗提供一种新的联合修复策略。

Objective

To preliminarily investigate the clinical efficacy of CTLA4Ig gene-transfected porcine skin combined with de-epidermized dermal tissue homogenate in the treatment of deep burn wounds.

Methods

A retrospective analysis was conducted on 28 patients with deep burns admitted to the Department of Burns and Wound Repair, Dongguan Houjie Hospital from June 2023 to June 2025. There were 22 males and 6 females, aged 21–67 years, with a mean age of (44.61±12.29) years. Patients were divided into the observation group (15 cases) and the control group (13 cases) according to the treatment protocol. The observation group received autologous de-epidermized dermis homogenate combined with CTLA4Ig gene-transfected porcine skin transplantation, while the control group received CTLA4Ig gene-transfected porcine skin transplantation alone. Wound healing time, postoperative inflammatory factor levels, and scar hyperplasia were compared between the two groups. Scar quality was evaluated using the Vancouver scar scale (VSS), including scores for pigmentation, thickness, vascularity, and flexibility, with total score calculated. Adverse events during treatment were recorded.

Results

Complete wound healing time was significantly shorter in the observation group than in the control group [(20.07±2.49) d vs. (26.92±6.49) d, P<0.001]. Interleukin-6 (IL-6) levels at 1 and 7 days postoperatively were significantly lower in the observation group (all P<0.05). At 3 months postoperatively, the VSS score was significantly lower in the observation group [(4.53±1.06) vs. (5.62±1.50), P<0.05].

Conclusion

De-epidermized dermis homogenate combined with CTLA4Ig gene-transfected porcine skin can significantly shorten wound healing time, reduce postoperative inflammatory response, and effectively improve scar quality, providing a novel combined repair strategy for the treatment of deep burn wounds.
