【摘要】 对广西肝癌高发区６～１２岁儿童无症状ＨＢｓＡｇ携带者４８５例追踪随访一年，观察其自然阴转。结果自然阴转率为２４９％，而７５．１％的研究对象依然保持其ＨＢｓＡｇ携带状态。其中男性自然阴转率（２０．９％）显著低于女性（３０．３％）（ｐ＜０．０５）。合并ＨＢｅＡｇ阳性者，ＨＢｓＡｇ自然阴转率（１９．６％）又显著低于ＨＢｅＡｇ阴性者（３２．５％）（Ｐ＜０．０１）。结果提示，在广西肝癌高发区男性ＨＢｓＡｇ携带率较高。更多还原

【Abstract】 A follow-up study for a peroid of one year was performed in a high primaryLiver Cancer(PLC)area in Guangxi to investigate the spontaneous disappearance of HBsAg in485 6～12 years old children,The results showed that the rate ofspontaneous disappearance ofHBsAg(RSD)of HBsAg in these children was only 24.9%,and that 75.1% of the children stilldisplayed HBsAg in their serum after a peroid of one year.The RSD of HBsAg of the boys(20.9%)was significantly lower thanthat of the girls(30.3%).Besides. RSD of HBsAg ofHBsAg carriers withHBeAg in their serum was significantly lower than those withoutHBeAg.The result suggeted that the rate of HBsAg carrier was usually higher in men than inwomen.更多还原
