病毒性肝炎是世界上危害人类生命健康较为严重的常见传染病。我国是肝炎发病率较高的国家,仅乙型肝炎患者就有2700万人,乙型肝炎表面抗原携带者约有一亿人。江苏省启东县是肝炎流行地区,甲型肝炎每隔4～5年暴发流行一次,乙型肝炎表面抗原(HBsAg)携带者为15％左右。严重地影响人们的工作、学习和生命。启东的流行病学调查结果表明,肝癌及乙型肝炎与硒关系较为密切。1980年我们对启东县永阳乡与西宁乡进行流行病学调查,发现永阳乡居民主粮硒含量较西宁乡低,而居民中乙型肝炎表面抗原阳性率及肝癌发生率均比西宁乡高,提示硒摄取量和肝炎、肝癌发生有一定关系。
Viral hepatitis is the world’s most common infectious disease that endangers the health of human beings. China is a country with a high incidence of hepatitis, with 27 million people suffering from hepatitis B and about 100 million people carrying hepatitis B surface antigen. Qidong County, Jiangsu Province is endemic to hepatitis A, hepatitis A outbreak every 4-5 years once, hepatitis B surface antigen (HBsAg) carrier is about 15%. Seriously affect people’s work, study and life. Qidong epidemiological survey showed that liver cancer and hepatitis B and selenium are more closely related. In 1980 we conducted an epidemiological survey of Yongyang and Xining townships in Qidong County and found that the content of selenium in Yongyang township residents was lower than that in Xining Township, while the positive rate of hepatitis B surface antigen and the incidence of liver cancer in residents were higher than those in Xining , Suggesting that selenium intake and hepatitis, liver cancer have a certain relationship.
