摘要
目的:探讨负压吸引疗法(NPWT)控制慢性下肢静脉溃疡(VLU)炎症反应,为溃疡创面自体皮肤移植创造条件的机制。方法:2018年6月至2021年12月,29例慢性下肢静脉溃疡患者,分为对照组(n=13)和观察组(n=16)。对照组采取常规静脉曲张手术加清创术,术后溃疡创面隔日常规换药;观察组除同对照组治疗外,术后溃疡创面持续负压引流1周。采集两组患者溃疡创面组织标本行组织学观察;ELISA检测IL-1β和IL-18蛋白水平变化;Western blotting检测凋亡相关斑点样蛋白(ASC)、核苷酸结合寡聚化结构域样受体蛋白3(NLRP3)、半胱氨酸天冬氨酸蛋白酶(Caspase-1)蛋白水平变化;生存曲线分析评估溃疡创面可行植皮时间。结果:术后7 d,观察组溃疡创面组织炎症反应较对照组明显减轻;观察组IL-1β和IL-18水平和ASC、NLRP3及Caspase-1水平均明显低于对照组;观察组溃疡创面可行植皮术的时间明显低于对照组。结论:NPWT通过抑制慢性下肢静脉溃疡创面组织炎症反应,为短时间内行创面自体皮肤移植创造条件。
Objective:To investigate the mechanism of inhibiting inflammatory response by negative pressure wound therapy in the chronic venous leg ulcer.Method:The clinical data of 29 patients with chronic VLU treated in Hechuan-Rhine Traditional Chinese Medicine Hospital of Shanghai from June 2018 to December 2021 were collected.According to different treatment methods,the patients were divided into the control group(n=13)and the observation group(n=16).The control group adopted routine varicose vein operations and debridement,routine dressing change was performed on the VLU wound every other day after operation.The observation group adopted debridement and then NPWT on the basis of routine varicose vein operations,the VLU wound was continuously drained with negative pressure for 1 week after operation.IL-1βand IL-18 levels were measured with ELISA.ASC、NLRP3 and Caspase-1 levels were detected with Western blotting.The autologous skin transplantation time of the two groups were calculated by survival curve analysis.Results:The inflammatory response was milder in the observation group than in the control group 7 days after operation.The results of ELISA showed that the levels of IL-1βand IL-18 in the observation group were lower than those in the control group.The results of Western blotting showed that the relative expression levels of ASC、NLRP3 and Caspase-1 in the observation group were lower than those in the control group.The survival curve analysis showed that the autologous skin transplantation time of the observation group was less than the control group.Conclusion:The inflammatory response can be distinctly alleviated by NPWT in the VLU,leading to better conditions for autologous skin transplantation within a short period.
