This paper provides serologic investigation of HBV in 302 persons who had a history of smallpox in Zhumadian County. The results showed that the HBsAg positivity rate (1.3%) was significantly lower than those of the control group 1 (8.3%) and 2 (8.6%) (P less than 0.001). The HBsAg positivity rate between the two control groups had no significant difference (P greater than 0.05). The HBV infection rate (19.2%) was also lower than those of control group 1 (47.7%) and 2 (51.3%) (P less than 0.001). There was not much difference between the two control groups. The determination of cellular immunity showed that the rosette positivity rate (75.93%) and lymphocyte conversion rate (70.39%) of the patients' group were higher than those of control group 1 (62.3% and 52.9%) and 2 (60.93% and 55.3%). It may suggested that patients having had smallpox might have enhanced cellular immunity which might interfere with HBV infection.
本文对驻马店县302名有天花病史者进行了乙肝病毒血清学调查。结果显示，乙肝表面抗原阳性率（1.3%）显著低于对照组1（8.3%）和对照组2（8.6%）（P<0.001）。两个对照组之间的乙肝表面抗原阳性率无显著差异（P>0.05）。乙肝病毒感染率（19.2%）也低于对照组1（47.7%）和对照组2（51.3%）（P<0.001）。两个对照组之间差异不大。细胞免疫测定显示，患者组的玫瑰花结阳性率（75.93%）和淋巴细胞转化率（70.39%）高于对照组1（62.3%和52.9%）和对照组2（60.93%和55.3%）。这可能表明患过天花的患者细胞免疫增强，可能会干扰乙肝病毒感染。
