摘要:

文题释义:

皮瓣缺血再灌注损伤:是指以往发生过缺血性改变的组织重新开放血流供应时,组织的缺血状态非但没有改善,反而加快了皮瓣组织缺血性坏死的进程。皮瓣缺血再灌注损伤是导致皮瓣移植术后坏死的主要原因。
代谢组学:是通过对生物体内的代谢物进行定性和定量分析,揭示生物体中代谢产物的变化规律。该研究利用代谢组学阐述皮瓣缺血再灌注损伤代谢过程的变化,了解疾病的发展过程、体内物质的代谢途径及发病机制。

背景:课题组前期研究证实消肿止痛合剂能够缓解皮瓣缺血再灌注损伤,但关于其代谢组学方面的作用机制研究尚未报道。
目的:探究消肿止痛合剂抗大鼠皮瓣缺血再灌注损伤的作用机制。
方法:建立大鼠皮瓣缺血再灌注损伤模型,利用代谢组学相关技术分析正常大鼠、模型大鼠以及给予消肿止痛合剂干预后大鼠血清样本中内源性代谢物的差异,检索及鉴定生物标志物并构建代谢通路。

结果与结论:消肿止痛合剂能够显著减轻皮瓣缺血再灌注损伤模型大鼠皮瓣组织的病理变化。筛选出显著性差异代谢物丙二酸和3-(3羟基苯基)丙酸,将差异代谢物导入在线数据库MetaboAnalyst 4.0及KEGG数据库进行代谢通路分析,得出消肿止痛合剂干预大鼠皮瓣缺血再灌注损伤后代谢的途径涉及嘧啶代谢、苯基丙氨酸代谢等代谢通路。结果表明,消肿止痛合剂通过对嘧啶代谢、苯基丙氨酸等代谢通路对大鼠皮瓣缺血再灌注损伤进行调节,为阐明消肿止痛合剂治疗大鼠皮瓣缺血再灌注损伤的作用机制提供了理论依据。

Abstract: BACKGROUND: Previous studies have confirmed that Xiaozhong Zhitong Mixture can alleviate ischemia-reperfusion injury of skin flaps, but its metabolomic mechanism has not been reported.
OBJECTIVE: To explore the mechanism of Xiaozhong Zhitong Mixture against ischemia-reperfusion injury of rat skin flaps. 
METHODS: A rat skin flap ischemia-reperfusion injury model was established. Related metabolomics techniques were used to analyze the endogenous levels of metabolite samples from normal rats, model rats and rats after intervention with Xiaozhong Zhitong Mixture. Relevant biomarkers were retrieved and identified and metabolic pathways were then constructed.
RESULTS AND CONCLUSION: Xiaozhong Zhitong Mixture could significantly reduce the pathological changes of skin flap tissue in rats with skin flap ischemia-reperfusion injury. Significantly differential metabolites, including malonic acid and 3-(3-hydroxyphenyl)propionic acid, were identified and imported into MetaboAnalyst 4.0 and KEGG databases for metabolic pathway analysis. After intervention, the metabolic pathways of Xiaozhong Zhitong Mixture included pyrimidine metabolism and phenylalanine metabolism. To conclude, Xiaozhong Zhitong Mixture improves ischemia-reperfusion injury of rat skin flap by regulating the metabolic pathways such as pyrimidine and phenylalanine metabolic pathways, which thereby provides a theoretical basis for clarifying the mechanism of Xiaozhong Zhitong Mixture in the treatment of ischemia-reperfusion injury of rat skin flap.

Key words: Xiaozhong Zhitong Mixture, metabolomics, flap ischemia-reperfusion, malonic acid, 3-(3hydroxyphenyl)propionic acid
