【摘要】 目的 :了解广西肝癌高发区高危人群 HBs Ag阴转情况。方法 :在广西肝癌高发区筛查高危人群 ,采用放射免疫法 (RIA)检测血清 HBs Ag,2年后随访复查。结果 :肝癌高危人群 HBs Ag年阴转率为 3.0 % ,在该人群中 HBs Ag年阴转率的年龄分布为低年龄组 (2 5～ 2 9岁 )和高年龄组 (5 0～ 5 4岁 )较高 ,中间各年龄组较低 ,除了 4 0岁组与 5 0岁组之间差异有统计学意义外(χ2 =3.87,P <0 .0 5 ) ,各年龄组之间差异无统计学意义。结论 :肝癌高危人群 HBs Ag阴转率不高 ,该人群 HBs Ag转阴率存在一定的年龄差异更多还原

【Abstract】 Objective:To understand the clearance of HBsAg in the high risk population of primary liver cancer (PLC) in the area of high risk of PLC of Guangxi. Methods:Screening high risk population of PLC in the area of high risk of PLC of Guangxi by using RIA to examine HBsAg in serum, and conducting follow ups two years later.Result:The annual rate of clearance of HBsAg is 3.0%. The age distribution of clearance of HBsAg was higher in the low age group (25~29 years) and the high age group (50~54 years), and is lower in the other age groups. The rate of clearance of HBsAg among these groups had not significant difference except for the two age groups of 25~29 years and 50~54 years(χ 2=3.87,P<0 05).Conclusion:The rate of clearance of HBsAg in the high risk population of PLC was lower and indicated some differences in ages.更多还原
