摘要:

目的 观察富氢生理盐水局部应用对3期压力性损伤大鼠创面修复的影响。方法 选取36只SPF级SD雄性大鼠,建立3期压力性损伤模型后(其中4只用于评判建模是否成功),随机分为对照组与干预组,每组16只。对照组使用生理盐水清创,干预组使用富氢生理盐水(氢含量≥2 mg/L)清创,均2次/d。于干预第0、3、7、10、14天观察创面愈合率;第3天检测血清肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)及血管内皮生长因子(VEGF)水平;第7、14天取创面组织行HE、Masson染色及Ki-67免疫组化检测,评估组织病理、胶原沉积与细胞增殖情况。结果 与对照组相比,干预组在第3、7、10、14天的创面愈合率均升高(P<0.05);干预第3天,干预组血清TNF-α、IL-6水平降低,VEGF水平升高(P<0.05)。HE和Masson染色显示,干预组创面愈合质量更优,第7、14天胶原体积分数均高于对照组(P<0.05)。免疫组化显示,干预组第7天Ki-67阳性细胞比率高于对照组(P<0.05)。结论 富氢生理盐水局部应用可促进3期压力性损伤创面愈合,其机制可能与减轻氧化应激与炎症反应、促进胶原合成与细胞增殖有关。

Abstract:

Objective To observe the effect of topical application of hydrogen-rich normal saline on wound repair in rats with stage 3 pressure injury. Methods Thirty-six SPF-grade male SD rats were selected to establish a stage 3 pressure injury model (among which 4 rats were used to evaluate successful modeling). Rats were then randomly divided into the control group and the intervention group, with 16 rats in each group. The control group received debridement with normal saline, while the intervention group received debridement with hydrogen-rich normal saline (with hydrogen content ≥ 2 mg/L), both twice daily. Wound healing rate was observed on the 0th, 3th, 7th, 10 and 14 days of intervention. On the day 3, serum levels of tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) were measured. On days 7 and 14, wound tissue samples were collected for HE staining. Masson staining and Ki-67 immunohistochemistry were used to evaluate tissue pathology, collagen deposition and cell proliferation. Results Compared with the control group, the wound healing rate was significantly higher on days 3, 7, 10 and 14 in the intervention group (P<0.05). On days 3 of intervention, serum levels of TNF-α and IL-6 were decreased, while VEGF level was increased (P<0.05) in the intervention group. HE and Masson staining showed the wound healing quality was better in the intervention group, and the collagen volume fraction was higher on days 7 and 14 than those in the control group (P<0.05). Immunohistochemistry showed that the percentage of Ki-67 positive cells on days 7 was significantly increased in the intervention group than that of the control group (P<0.05). Conclusion Topical application of hydrogen-rich normal saline can promote wound healing in stage 3 pressure injury, and the mechanism may be associated with alleviating oxidative stress and inflammatory responses, as well as promoting collagen synthesis and cell proliferation.
