为了解庚型肝炎病毒（ＨＧＶ）感染对肝功能的影响，用逆转录－聚合酶链反应（ＲＴ－ＰＣＲ）技术检测８５例病毒性肝炎患者ＨＧＶ－ＲＮＡ并检测其肝功能指标。结果显示ＨＧＶ在病毒性肝炎患者中感染率为１０．６％（９／８５）。除１例为单纯感染外，其余８例均以与ＨＢＶ或ＨＣＶ重叠感染形式出现。对照ＨＧＶ和ＨＢＶ重叠感染组与ＨＢＶ单纯感染组之间肝功能指标，未发现明显差异。表明与ＨＧＶ重叠感染未加重肝功能损害 To understand the effect of hepatitis G virus (HGV) infection on liver function, HGV-RNA was detected in 85 patients with viral hepatitis by reverse transcription-polymerase chain reaction (RT-PCR) and liver function was measured. The results showed that the infection rate of HGV in patients with viral hepatitis was 10.6% (9/85). Except for 1 case of simple infection, the remaining 8 cases appeared as overlapping infection with HBV or HCV. There was no significant difference in liver function between control HGV and HBV overlap infection group and HBV infection alone group. It showed that overlapping with HGV infection did not aggravate liver damage
