摘要
硒是人体内谷胱甘肽过氧化物酶（GSH-Px）的重要组分。GSH-Px能对抗体内有氧代谢过程中所产生的过氧化物和自由基对细胞的损害和破坏。我国居民普遍缺硒，慢性乙型肝炎病人缺硒更为明显。补硒能提高机体免疫功能，降低高危人群的肝癌发生率，有利于慢性肝炎病人改善肝功能，并有抗肝纤维化作用。是一项显示远期疗效的辅助治疗措施。有机硒吸收利用率高，毒副作用小，将逐步取代无机硒在临床上的应用。
Selenium is an essential constituent of glutathione peroxidase （GSH-Px）. GSH-Px can counteract the cell injury of peroxides and free radical produced in the course of aerobic metabolism. The residents in China generally lack selenium, and the chronic hepatitis B patients are more obvious. In chronic hepatitis patients, selenium supply can improve the immune function of organism, reduce the liver cancer incidence among the high-risk group; improve liver function and decrease hepatic fibrosis. Selenium supply is an assistant therapy method with long-term result. Organic selenium will gradually replace mineral selenium clinically, as it has higher intake rate and lower side effect or toxicity.
