【摘要】 目的 系统分析负压封闭引流对开放性骨折创面的治疗效果。 方法 计算机检索中国期刊全文数 据库 (中国知网)、 中国生物医学文献数据库 (CBM)、 中文科技期刊数据库 (维普)、 中国学术期刊数据库 (万 方)、 The Cochrane Library、 PubMed、 OVID、 Web of Science、 CINAHL 等数据库建库至 2018 年 8 月公开发表的负 压封闭引流治疗开放性骨折创面的相关文献, 根据纳入与排除标准筛选符合标准的文献, 采用 Cochrane 5. 1.0 手 册中的偏倚风险评估标准对纳入文献进行质量评价, 采用 Rev Man 5.3 软件对纳入文献进行 Meta 分析、 TSA 0. 9 软件对纳入文献进行试验序贯分析。 结果 共纳入符合标准的文献 10 篇, 包含开放性骨折患者 1097 例。 Meta 分 析结果显示, 创面行负压封闭引流治疗的开放性骨折患 者 创 面 感 染 率 明 显 低 于 常 规 治 疗 [ RR = 0.43, 95% CI (0.31,0. 60), P < 0. 001], 治疗有效率明显高于常规治疗 [ RR = 1.33, 95% CI (1.19, 1. 50), P < 0.001], 创面愈合时间明显短于常规治疗 [SMD = - 4. 87, 95% CI ( - 7.21, - 2.52), P < 0.001]; 试验序贯分 析结果显示, 各结局指标在样本量达到期望信息量之前已获得肯定结果。 结论 与常规治疗方法相比, 负压封闭 引流能更有效降低开放性骨折创面感染率, 提高治疗有效率, 缩短创面愈合时间。

Diabetic foot ulcer (DFU) frequently leads to non-traumatic amputation and finally even death. However, the mechanism of DFU is not fully understood. Interleukin 25 (IL-25), an alarmin cytokine that responds to tissue injury, has been reported to participate in tissue regeneration and maintaining glucose homeostasis. However, the role of IL-25 in diabetic wound healing remains unknown. Here, we showed that interleukin 17 receptor B (IL- 17RB), the functional receptor of IL-25, was significantly inhibited in the wound skin of both diabetic patients with DFU and streptozotocin (STZ)-induced diabetic mice. Topical administration of recombinant IL-25 protein improved angiogenesis and collagen deposition in the wound bed and thus ameliorated delayed diabetic wound healing. IL- 25 increased endothelial-specific CD31 expression in diabetic wounds and exogenous IL- 25 protected endothelial cells from high glucose-impaired cell migration and tube formation in vitro. We further revealed that IL-25-mediated-IL-17RB signaling rescued the downregulation of Wnt/b-catenin pathway both in vivo in diabetic mice and in vitro in HUVECs and induced the phosphorylation of AKT and ERK 1/2 in HUVECs under high glucose conditions. This study defines a positive regulatory role of IL-25-mediated-IL- 17RB signaling in diabetic wound healing and suggests that induction of IL-25-mediated IL-17RB signaling may be a novel therapeutic strategy for treating poor healing diabetic wounds.
