摘要:

文题释义:
川芎嗪呋咱拼合物:课题组合成的一种化合物,该化合物在动物体内可以降解为一分子的川芎嗪和一氧化氮,同时发挥川芎嗪和一氧化氮两种物质的药物作用。
肾缺血再灌注损伤:是肾组织缺血后重新获得血流灌注和(或)氧供后,缺血的肾组织并未恢复其功能,相反细胞功能代谢障碍及结构破坏相比较于缺血时更加严重,使得肾功能进一步恶化的综合征。其机制可能与氧自由基生成过多、细胞内Ca2+超载、炎症因子及递质的参与、细胞凋亡、膜脂质过氧化、一氧化氮含量变化等多因素参与引起的肾脏组织结构紊乱、功能代谢异常有关。
背景:文献报道,川芎嗪和一氧化氮都能减轻缺血再灌注引起的急性肾损伤。课题组合成一种在动物体内可以降解成一分子川芎嗪单体和一氧化氮的川芎嗪呋咱拼合物(605-1)化合物,其具有双重防治缺血再灌注损伤的作用。                             
目的:观察605-1防治小鼠急性肾缺血再灌注损伤的作用,并探讨其作用的机制。
方法:将48只雄性C57小鼠随机分为6组:假手术组,模型组,单独给药组,模型给药低、中、高浓度组。假手术组和单独给药组小鼠行假手术,不作肾缺血处理;模型组和模型给药各组小鼠建立肾缺血再灌注引起急性肾损伤模型。6组均于术前24 h及2 h进行预处理,假手术组和模型组腹腔注射生理盐水;单独给药组及模型给药低、中、高浓度组分别予以川芎嗪呋咱拼合物(605-1),10,20,30 mg/kg。于缺血再灌注24 h后,测定血清中肌酐、尿素氮水平及肾组织的病理变化;在蛋白水平检测肾组织肾损伤分子1、Nox4、p65、P-p65表达;在RNA水平检测肾组织肾损伤分子1、肿瘤坏死因子α、白细胞介素6、单核细胞趋化蛋白1的表达。所有动物实验程序均由安徽医科大学动物实验伦理委员会批准。
结果与结论:①单独给药组(30 mg/kg)无肾毒性;②与模型组相比,模型给药各组肾缺血再灌注小鼠肾组织病理显示肾组织病理肾小管扩张和刷状边界丢失、管状细胞丢失明显减轻,血清中肌酐、尿素氮水平显著降低;肾损伤分子1在肾组织蛋白水平、mRNA水平表达也明显下降,肾组织免疫组化中肾损伤分子1表达的分布、数量明显下降;Nox4、p65、P-p65的蛋白水平呈下调表达;肿瘤坏死因子α、白细胞介素6、单核细胞趋化蛋白1的mRNA水平显著降低;③结果说明,605-1对小鼠急性肾缺血再灌注损伤有防治作用,其机制与抗氧化应激、抑制炎症反应有关。

Abstract: BACKGROUND: Ligustrazine and nitric oxide can both reduce acute kidney injury caused by renal ischemia-reperfusion. Our team synthesized a compound of ligustrazine furoxan (605-1) which can be degraded into ligustrazine monomer and nitric oxide in animals. This compound has therapeutic and preventive effects against ischemia-reperfusion injury.
OBJECTIVE: To observe the therapeutic and preventive effects of 605-1 against acute renal ischemia-reperfusion injury in mice, and to explore its mechanism.
METHODS: Forty-eight male C57 mice were randomly divided into six groups: sham operation group, model group (ischemia-reperfusion group), single administration group (605-1, 30 mg/kg), low, medium and high dose groups (ischemia-reperfusion+10, 20, 30 mg/kg 605-1, respectively). Mice in the sham operation group and the single administration group underwent sham operation without renal ischemia treatment, and those in the model group and the three administration groups were used to make acute kidney injury models caused by renal ischemia-reperfusion. Pre-treatments in each group were conducted at 24 and 2 hours before operation. Normal saline was intraperitoneally given in the sham operation and model groups. After 24 hours of ischemia-reperfusion, the levels of serum creatinine and urea nitrogen and the pathological changes of renal tissue were measured. The expression of kidney injury molecule 1, Nox4, p65, and P-p65 was detected at the protein level. The expression of kidney injury molecule 1, tumor necrosis factor α, interleukin 6, and monocyte chemoattractant protein 1 were detected at the RNA level. All animal experiment procedures were approved by the Animal Ethics Committee of Anhui Medical University.
RESULTS AND CONCLUSION: The single administration group (30 mg/kg) had no renal toxicity. Compared with the model group, in the low, medium and high dose groups, histomathological examinations of the renal tissue showed pathological renal tubule dilation and brush border loss, tubular cell loss was significantly reduced, serum creatinine and urea nitrogen levels were significantly reduced; the protein and mRNA levels of kidney injury molecule 1 in renal tissue also decreased significantly, and immunohistochemical examination showed that the distribution and quantity of kidney injury molecule 1 expression in renal tissue decreased significantly; the protein levels of Nox4, p65, and P-p65 were down-regulated; the mRNA levels of tumor necrosis factor-α, interleukin-6 and monocyte chemoattractant protein 1 were significantly reduced. To conclude, 605-1 has a preventive effect against renal ischemia-reperfusion injury in mice, and its mechanism is related to anti-oxidative stress and inhibition of inflammation.
