The activities of CTL were detected as usual with EBV-transformed lymphoblastoid cell line (BLCL) as target cells. The results showed that the CTL clone could recognized and killed the target cells with specificity of nucleocapsid protein of Hantaan virus (HTNVNP) with the cytotoxicity percentages of 50.2%, 25.4% and 39.0% respectively. These results demonstrated that the antigenic epitopes of HTNVNP mainly located on the C-terminal of the viral nucleocapsid protein.展开更多

Thirty-one serum samples of clinically diagnosed patients with HFRS were examined by RT-PCR to decide the genetic subtype. On the basis of infection season, the serum samples were divided into two groups： winter （Nov, 2003--Feb, 2004）, spring and summer （April, 200d--Sep, 2004）. Further analysis was performed in combination with clinical symptoms. It was found that among the total 31 samples, 22 were sero-positive. Among 14 serum samples in winter, 8 were sero-positive, of which 5 cases were of type Ⅰ （Hantaan virus, HTNV） and 3 of type Ⅱ （Seoul virus, SEOV）. Among 17 samples in spring and summer, 14 were sero-positive, of which 5 cases were of type Ⅰ and 9 of type Ⅱ . So it concludes that both of the two types of Hantavirus exist in Heilongjiang. The type Ⅰ is the main pathogen of HFRS in winter, and typeⅡ is the main in spring and summer.展开更多

It encompasses a broad spectrum of clinical presentations, ranging from unapparent or mild illnesses to fulminant hemorrhagic processes. Among the various complications of HFRS, acute pancreatitis is a rare find. In this report, based on clinical data, laboratory and radiologic examination findings, we describe a clinical case, with HFRS from Dobrava virus, associated with acute pancreatitis. The patient was successfully treated by supportive management. Clinicians should be alert to the possibility of HFRS when examining patients with epidemiological data and symptoms of acute pancreatitis.展开更多
