摘要
目的：探讨苦参碱对非小细胞肺癌(non-small lung cancer cell，NSCLC)顺铂耐药性的逆转作用及其机制。方法：MTT法检测细胞存活率；采用试剂盒检测细胞乳酸脱氢酶及caspase-3活性，考察核因子E-2-相关因子2(nuclear factor-E2-related factor，Nrf2)激动剂对NSCLC细胞凋亡及膜连蛋白A4(Annexin A4)表达的影响，同时考察苦参碱对NSCLC顺铂耐药的改善作用及对Nrf2/Annexin A4的调控作用。结果：使用Nrf2激动剂后，NSCLC细胞顺铂耐药显著，顺铂耐药细胞存活率较普通肺癌细胞显著升高，凋亡率显著降低，Annexin A4表达明显升高，而苦参碱可以显著抑制Nrf2诱导的Annexin A4表达，提高细胞对顺铂的敏感性，促进细胞凋亡发生。结论：苦参碱对人NSCLC顺铂耐药细胞株顺铂耐药性有改善作用，其机制可能与调节Nrf2/Annexin A4有关。

Abstract
Objective: To investigate the reversal effect of Matrine on cisplatin-resistant non-small cell lung cancer (NSCLC) cells and its mechanism. Methods: MTT assay was used to detect cell viability, lactate dehydrogenase (LDH) and caspase-3 (caspase-3) activity, and Nrf2 agonists were given to investigate the effects of Nrf2 on apoptosis and Annexin A4 expression in NSCLC cells. Matrine was also given to investigate its effect on cisplatin resistance and regulation of Nrf2/Annexin A4 in NSCLC. Results: MTT assay showed that Nrf2 agonist significantly inhibited the cisplatin resistance of NSCLC cells, the survival rate of cisplatin-resistant NSCLC cells was significantly higher than that of normal lung cancer cells, the apoptosis rate was significantly decreased, the expression of Annexin A4 was significantly increased, while matrine significantly inhibited Nrf2-induced Annexin A4 expression, and significantly increased the cisplatin resistance of NSCLC cells. The sensitivity of platinum promotes cell apoptosis. Conclusion: Matrine can improve the cisplatin resistance of human NSCLC cisplatin-resistant cell line, and the mechanism may be related to the regulation of Nrf2/Annexin A4.
