目的　 探讨乙型肝炎病毒（HBV）表面抗原（HBsAg）阳性肝硬化患者血清中HBV前S1抗原(前S1抗原)、HBV e抗原（HBeAg）及HBV核酸定量检测（HBV DNA）相关性。 方法　 2008年7月－2011年5月对97例HBsAg阳性肝硬化住院患者和50份HBsAg阴性的健康体检者血清进行前S1抗原、HBV血清标志物检测及实时荧光定量PCR检测HBV DNA结果进行分析。 结果 　97份HBsAg阳性肝硬化患者血清中，前S1抗原、HBeAg及HBV DNA阳性率分别为53.6%（52/97）、22.7%（22/97）及61.8%（60/97）。22例HBeAg阳性血清中，前S1抗原阳性18例（81.8%）， HBV DNA阳性20例（90.9%)。75例HBeAg阴性血清中，前S1抗原阳性34例（45.3%），HBV DNA阳性40例（53.3%），两者的前S1抗原与HBV DNA结果间都具有很好的相关性。HBV DNA含量与前S1抗原及HBeAg阳性结果显示：HBsAg阳性的肝硬化患者血清中HBV DNA阴性率为38.1%（含量＜103 copies/mL），而阳性检出率HBV DNA含量主要集中在103～105 copies/mL，占81.7%（49/60），HBV DNA含量＞105 copies/mL占18.3%（11/60）。 结论　 HBsAg阳性的肝硬化患者血清中主要以HBV非HBeAg阳性血清学模式为主，HBV DNA阳性检出率的含量主要集中在103～105 copies/mL。前S1抗原在HBeAg阳性血清中与其含有HBsAg病毒及HBeAg阳性患者具有很好的相关性，而在HBeAg阴性血清中存在着差异。
Objective　 To study the correlation among Pre-S1 antigen, HBeAg and HBV DNA results in patients with HBsAg-positive liver cirrhosis. Methods　 We retrospectively analyzed the serum pre-S1-antigen, HBV serum markers and real-time quantitative PCR HBV DNA results in 97 patients with HBsAg-positive liver cirrhosis and 50 HBsAg-negative healthy volunteers in our hospital from July 2008 to May 2011. Results　 Among the 97 samples of HBsAg-positive liver cirrhosis patients’ serum, the positive rates of Pre-S1 antigen, HBeAg and HBV DNA were 53.6% (52/97), 22.7% (22/97) and 61.8% (60/97), respectively. In the 22 samples of HBeAg-positive serum, the number of positive pre-S1 antigen and HBV DNA was 18 (81.8%) and 20, respectively. In the 75
samples of negative HBeAg serum, the number of positive pre-S1 antigen and HBV DNA was 34 (45.3%) and 40 (53.3%) respectively. The pre-S1 antigen was correlated well with HBV DNA results in both the two groups. HBV DNA level, pre-S1 antigen and HBeAg-positive results showed that the serum HBV DNA negative rate of HBsAg-positive patients with cirrhosis was 38.1% (＜103 copies/mL), while the positive rate of HBV DNA level was mainly concentrated at 103~105 copies/mL, accounting for 81.7% (49/60), and HBV DNA level over 105 copies/mL
accounted for only 18.3% (11/60). Conclusions　 HBsAg-positive patients with cirrhosis mainly have a serum non-HBeAg-positive HBV serology pattern, and HBV DNA positive rate of the content is mainly concentrated at 103~105 copies/mL. There is a good correlation between pre-S1 antigen in HBeAg-positive serum and patients with HBsAg virus or positive HBeAg, while for Pre-S1 antigen in HBeAg-negative serum, it is quite different.
