摘要

目的探讨氢气对非小细胞肺癌的抑制作用及其机制。

方法将16只BALB/c雄性荷瘤裸鼠随机分为对照组和氢气组,氢气组给予吸入60%氢气+40%空气2 h/d处理。干预4周后结束实验,测量瘤体的体积及重量,采用苏木精-伊红染色法、免疫组织化学方法、实时定量聚合酶链式反应及Western blot检测肿瘤组织中Ki-67、环氧化酶2(COX-2)、血管内皮生长因子(VEGF)的含量。

结果与对照组相比,氢气组瘤体的体积及重量显著减小,氢气组Ki-67、COX-2、VEGF的mRNA、蛋白表达显著减少,且其病理形态及细胞异质性相对于对照组存在显著差异。

结论氢气干预可抑制非小细胞肺癌生长,其机制与抑制Ki-67、COX-2、VEGF表达有关。

ABSTRACT

ObjectiveTo investigate the inhibitory effect of hydrogen on non-small cell lung cancer and its mechanism.

MethodsSixteen BALB/c male tumor-bearing nude mice were randomly divided into control group and hydrogen group.Hydrogen group was treated for four weeks (60% hydrogen+ 40% air, two hours a day.The volume and weight of the tumor were measured.The levels of Ki-67, cyclooxygenase-2 (COX-2), and vascular endothelial growth factor (VEGF) in the tumor tissues were detected by hematoxylin-eosin staining, immunohistochemistry, real-time quantitative polymerase chain reaction and Western blot.

ResultsThe tumor volume and weight of the hydrogen group were significantly lower than those of the control group.The mRNA and protein contents of Ki-67, COX-2 and VEGF in the hydrogen group were significantly reduced, and its pathological morphology and cellular heterogeneity were significantly different from the control group.

ConclusionsHydrogen can inhibit non-small cell lung cancer, which is related to the repression of Ki-67, COX-2 and VEGF.

据2014年WHO及国际癌症研究机构发布的世界癌症报告显示,癌症发病率和病死率呈现持续上升的趋势 [ 1 ],肺癌居于首要地位,但目前缺乏有效治愈方法。在1520年氢气作为可燃性气体出现在人们的视线当中 [ 2 ],之后主要作为清洁能源气体被广泛研究。直到2007年日本学者 [ 3 ]发现氢气具有选择性抗氧化作用,氢分子的生物学功能逐渐得到学者广泛关注,其在许多疾病上具有一定的效果,如帕金森症 [ 4 ]、糖尿病 [ 5 ]、代谢综合征 [ 6 ]、线粒体疾病 [ 7 ]等。但有关氢气在肺癌方面的作用效果目前尚缺乏相关的研究。本研究主要是针对氢气干预非小细胞肺癌的治疗效果及其机制进行探讨。
