本文对郑州铁路中心医院１９９１年７月至１９９２年６月１８１例临床诊断为病毒性肝炎住院患者，采用ＥＬＡ、ＲＩＡ、Ｄｉｇ－ＨＢＹ－ＤＮＡ及ＰＣＲ技术进行病原学诊断。结果表明，１８１例患者，除２３例各项指标全阴性外，能分型者１５８例，检出率为８７．２９％。１５８例中，急性肝炎１５５例，慢性肝炎２例，重型肝炎１例。感染单一型１１０例，混合感染４８例。分型结果ＨＡ占３７．８５％、ＨＢ占４６．７３％、ＨＣ占１４．４９％，ＨＤ占０．４７％、ＨＥ未检出；从１５份ＨＢ尿液用Ｄｉｇ－ＨＢＹ－ＤＮＡ探针，检出１例阳性。半年内各型肝炎患者有注射史均在５５．１０％－６３．６３％，ＨＢ、ＨＣ分别占６５．３１％和５２．６４％。对此提出相应对策。
In this paper, Zhengzhou Railway Central Hospital from July 1991 to June 1992 181 cases were diagnosed as viral hepatitis inpatients, using ELA, RIA, Dig-HBY-DNA and PCR for etiological diagnosis. The results showed that in 181 patients, except for the 23 items of all negative, the type of 158 cases, the detection rate was 87.29%. Of the 158 patients, 155 were acute hepatitis, 2 were chronic hepatitis, and 1 was severe hepatitis. 110 cases of single infection, mixed infection in 48 cases. The typing results of HA accounted for 37.85%, HB accounted for 46.73%, HC accounted for 14.49%, HD accounted for 0.47%, HE was not detected; from 15 HB urine Dig-HBY-DNA probe , One case was positive. Within half a year, patients with various types of hepatitis had an injection history of 55.10% -63.63%, with HB and HC accounting for 65.31% and 52.64% respectively.
