摘　　要：利用庚型肝炎病毒（ＧＢＶ－Ｃ／ＨＧＶ）ＮＳ３～５区序列合成了四组套式引物，建立了灵敏、特异的庚型肝炎病毒ＲＮＡ双扩增聚合酶链反应（ＰＣＲ）检测方法。用此方法检测了１０份庚型肝炎病毒抗体阳性患者血清及１０份阴性的健康人血清。前者不同组引物的检出率为ＮＳ３（１）引物９份阳性，ＮＳ３（２）引物８份阳性，ＮＳ４引物４份阳性，ＮＳ５（１）引物５份阳性，ＮＳ５（２）引物９份阳性；后者各组引物检测均为阴性。结果表明，庚型肝炎病毒不同区域引物用于ＲＴ－ＰＣＲ检出率差异较大。ＮＳ３（１）及ＮＳ５（２）这两组引物检出率最高，更适合用于ＲＴ－ＰＣＲ检测庚型肝炎病毒ＲＮＡ。A double polymerase chain reaction, involoving nested primers deduced from NS3-5 regions of the hepatitis G virus (GBV-c/HGV) genome, was developed for a sensitive and specific detection of GBV-C (HGV) RNA. With this method, 10 anti-HGV positive patients with non A-E hepatitis and 10 healthy subjects were tested. Among 10 patients, GBV-C RNA was detected in 9, 8, 4, 9 patients by the NS-3 (1) primers, the NS3(2) primers, the NS4 primers, the NS5(1) primers and the NS5(2) primers respectively. Control sera from 10 healthy subjects did not reveal GBV-C (HGV) RNA by any set of the primers. These data suggest that the detection rate of GBV-C (HGV) RNA is different in various set of primers, the NS3(1) and the NS5(2) primers are superior to other primers and are more suitable for RT-PCR of GBV-C (HGV) RNA.
