摘要 为了选择更为敏感,特异,快速的肾综合征出血热(HFRS)的诊断方法。我们建立了碘化钠—异硫氰酸胍—氯仿法提取汉坦病毒(HV)核酸(RNA)用于逆转录一聚合酶链反应(RT-PCR)检测不同病型HFRS患者一周内血清中HV-RNA且与酶联免疫吸附法(ELISA)检测HFRS-IgM进行比较。45例HFRS患者血清中HV-RNA阳性率为82.2%,其中轻、中、重型阳性率分别为75%,78.5%,86.9%。HFRS-IgM阳性率55.5%,其中轻、中、重型阳性率分别为37.5%,50.0%, 65.2%。RT-PCR法检出率高于ELISA法,差别有显著性。RT-PCR法和ELISA法均可以用于HFRS的早期诊断。但前者更为敏感。

Abstract Selecting a more sensitive,specincearly diagnosis for hernorrhagic fever with renaisyndrome(HFRSL). A reverse-transcriptionpolymerase chain reaction(RT-PCR)detecting the hantavirus(HV)RNA in the sera Ofdifferent.types HFRS patients with Nal-guanidiym-thioeyanate-chloroform method extractingHV RNA was established and ELISA detecting the lgM was also performed for conparision.Thetotal pasitive rate of 45 HFRS cases ahd different type (mile,mediun,serious )patient'spositive rates are 82.2%,(75%,78%,86.9%)respectively by RT-PCR and55.5%(37.5%,50%,65.2%)respectively by EUSA.The detecting rates by RT-PCR aresignmeantlyhigher than those by ELISA.conclusions:Results suggested that both RT-PCR andELISA couldbe used for early diagnosis ofHFRS,and the RT.PCR is more sensitive than EUSA.
