摘　　要：胃癌是消化系统最常见的恶性肿瘤,而我国是胃癌高发区,其发病率和死亡率均高于世界平均水平。在我国大多数患者明确诊断时已进入进展期,所以大多数患者再行手术切除后还需放化疗治疗。近来随着对胃癌的研究深入,可通过对胃癌肿瘤标本行分子检测给予患者药物靶向治疗,实现个体化治疗。RNA干涉(RNAi)技术被广泛用于基因功能的研究,并且在哺乳动物研究中得到飞速发展.si RNA是在RNAi中起中心作用,其可抑制特定m RNA,以调节不同蛋白在肿瘤发生时的异常表达。对si RNA的研究将为胃癌的基因治疗供更广阔的空间。Gastric cancer is the most common malignant neoplasm of digestive system.Our country is a high-risk area of gastric cancer and its morbidity and mortality are higher than the world average.Most patients have entered the advanced stage when they were diagnosed with gastric cancer.So most of them need to radiotherapy and chemotherapy after surgery.As the research moves along,gastric cancer patients can get drug targeted therapy through the molecular detection of tumor specimens to realize the personalized treatment.RNA interference （RNAi） technology is widely used for gene function study,and get the rapid development in the study of mammals.siRNA plays a central role in RNAi,which possesses specific inhibits a mRNA,to adjust the different protein abnormal expressions in tumors occur.The study of siRNA will provide a broader space for gastric cancer gene therapy.
