肺癌是世界上发病率和死亡率均较高的疾病之一,因缺乏早期诊断指标及有效的治疗方法,以及环境污染及人们吸烟等不良生活习惯,其死亡率一直很高。近年来,分子生物学技术的应用为其提供了新的研究方法。n-3系多不饱和脂肪酸,属必需脂肪酸,包括α—亚麻酸(linolen icac id)、二十? Lung cancer is one of the diseases with high morbidity and mortality rate in the world. Due to the lack of early diagnosis indexes and effective treatment methods, as well as the bad habits such as environmental pollution and people smoking, lung cancer has a high mortality rate. In recent years, the application of molecular biology technology has provided a new research method for it. n-3 polyunsaturated fatty acids, are essential fatty acids, including α-linolenic acid (linolen icac id), twenty
