文题释义:
川芎嗪:是一种吸收快、代谢快、半衰期短的生物碱,但生物利用度低,作者所在团队研制的川芎嗪纳米制剂,利用纳米技术增加药物颗粒溶解度,提高生物利用度,并结合与聚乳酸发挥覆盖隔离作用。川芎嗪纳米制剂使用方便,靶向性给药,生物利用度高,且具有良好的生物相容性和低细胞毒性,有效弥补了川芎嗪的代谢短板,可促进川芎嗪在临床上的应用。
Nrf2-ARE信号通路:Nrf2属于CNC转录因子家族成员,含有6个不同的功能区,分别被命名为Neh1到Neh6。生理状态下,Nrf2与Keap1偶联存在于细胞质中并经泛素化降解,当受到有害刺激时,Nrf2与Keap1解离并活化转位进入细胞核,在核内与ARE结合激活Nrf2-ARE信号通路,诱导机体抗氧化基因表达,防止自由基产生。
 
 
背景:氧化应激是术后腹腔粘连形成的重要机制之一,转录因子NF-E2相关因子2(nuclear factor-E2-related factor 2,Nrf2)-抗氧化反应元件(antioxidant response element,ARE)信号通路是重要的内源性抗氧化应激通路,课题组前期研究发现川芎嗪纳米喷雾剂可抑制实验性大鼠术后腹腔粘连形成,并且川芎嗪具有抗氧化作用。
目的:观察川芎嗪纳米喷雾剂对术后腹腔粘连大鼠Nrf2-ARE信号通路相关蛋白、mRNA表达的影响,以及对抗大鼠腹腔粘连的作用机制。
方法:将SD大鼠随机分为假手术组、模型组、川芎嗪组和透明质酸钠组,假手术组打开腹腔后即缝合不予造模,模型组打开腹腔予什锦锉刀摩擦回盲部浆膜层以制备腹腔粘连模型,川芎嗪组和透明质酸钠组造模方法与模型组相同,关腹前分别予川芎嗪纳米喷雾剂和透明质酸钠凝胶创面给药。

结果与结论:与模型组相比,川芎嗪纳米喷雾剂可降低实验性术后腹腔粘连大鼠活性氧、基质金属蛋白酶抑制因子1水平,升高基质金属蛋白酶9水平,上调Nrf2、血红素加氧酶1 mRNA和蛋白表达水平。川芎嗪纳米喷雾剂对大鼠术后腹腔粘连具有抑制作用,其机制可能与调节Nrf2和血红素加氧酶1mRNA及蛋白水平从而激活Nrf2-ARE信号通路抗氧化作用有关。

Abstract:

BACKGROUND: Oxidative stress is one of the important mechanisms of postoperative abdominal adhesion. The nuclear factor-E2-related factor 2 (Nrf2)-antioxidant response element (ARE) signal pathway is an important endogenous anti-oxidation stress pathway. Our previous study found that ligustrazine nano-spray can inhibit the formation of postoperative abdominal adhesion in rats, and moreover, ligustrazine has an anti-oxidation effect.

OBJECTIVE: To observe the effect of ligustrazine nano-spray on the expression of mRNAs and proteins related to the Nrf2-ARE signal pathway in rats with abdominal adhesion, and to investigate the mechanism by which ligustrazine nano-spray inhibits abdominal adhesion via regulating the Nrf2-ARE signal pathway.
METHODS: Sprague-Dawley rats were randomly divided into sham group, model group, ligustrazine group and sodium hyaluronate group. In the sham group, only laparotomy was performed without modeling. In the model group, an abdominal adhesion model was created but no drug was used. In the ligustrazine group, ligustrazine nano-spray was used on the wound before incision suturing. In the sodium hyaluronate group, sodium hyaluronate was applied on the wound before incision suturing.
RESULTS AND CONCLUSION: Compared with the model group, ligustrazine nano-spray reduced the levels of reactive oxygen species, tissue inhibitor of matrix metalloproteinase 1, but increased the level of matrix metalloproteinase 9 in the rat serum. The expression of Nrf2 and HO-1 mRNA and proteins was also up-regulated in the ligustrazine group relative to the model group. Therefore, ligustrazine nano-sprays can inhibit abdominal adhesions in rats, and its mechanism may be related to the regulation of Nrf2 and heme oxygenase 1 mRNA and proteins expression and the activation of Nrf2-ARE signaling pathway.
