肺癌是我国最常见的恶性肿瘤之一,死亡率居恶性肿瘤之首。目前缺乏对肺癌的早期诊断方法,而且患者术后存活率极低(30%),因此迫切需要开发新型抗癌药物,提高肺癌患者的存活率与生存质量。目前关于三氧化二砷(As_2O_3)联合吉西他滨(GEM)作用于肺癌细胞的报道很少,本研究探讨了两种物质体外对肺癌细胞A549的作用效果,为临床治疗肺癌提供理论基础。1材料与方法1.1材料A549细胞系来自泸州医学院;As_2O_3购自
Lung cancer is one of the most common malignant tumors in our country, with the highest mortality rate among malignant tumors. Currently there is a lack of early diagnosis of lung cancer, and the survival rate of patients after surgery is very low (30%), so the urgent need to develop new anti-cancer drugs to improve lung cancer survival and quality of life. At present, there are few reports about the effect of arsenic trioxide (As_2O_3) combined with gemcitabine (GEM) on lung cancer cells. This study explored the effect of two substances on A549 lung cancer cells in vitro and provided the theoretical basis for the clinical treatment of lung cancer. 1 Materials and Methods 1.1 Materials A549 cell line from Luzhou Medical College; As 2 O 3 from
