Objective To study the occurring regulation of antibody of Urbani sever acute respiratory syndrome (SARS)-associated coronavirus after onset of illness in patients with SARS and investigate the co-infection status of Chlamydiae pneumoniae (Chlamydiae P.) , Mycoplasma pneumoniae (Mycoplasma P.), Adenovirus, Respiratory Syncytia virus (RSV). Methods Serum Antibody IgM and IgG of Urbani SARS-associated coronavirus of 43 patients with SARS and 10 patients with other diseases except SARS at the two different phases of illnesses were detected with immune fluorescent technique. Antibody IgM and IgG of Chlamydiae P., Mycoplasma P., Adenovirus and RSV in the above samples were detected with enzyme-linked immunosorbent assay (ELISA). Results 40 cases' infection of were Urbani SARS-associated coronavirus were determined (93.02%) and 3 cases were negative (6.98%). 10 patients with other diseases except SARS have negative serum Antibody IgM and IgG of Urbani SARS-associated coronavirus. Recent infection rates of Chlamydiae P., Mycoplasma P., Adenovirus and RSV were 25.58%, 16.28%, 6.98% and 4.65% , respectively, and former infection rates of these pathogens were 39.53%, 34.88%, 27.91% and 0, respectively. Antibody IgM of Urbani SARS-associated coronavirus occurred at the same time of onset of fever. Positive rates of IgM were respectively 69.57% and 62.96% in 8~14 days and 15~33 days after onset of fever, and there were no remarkable difference between them, but they were re-markably higher than that in 1~7 days after onset of fever (16.67%). Antibody IgG of Urbani SARS-as-sociated coronavirus occurred at the 6th day after onset of fever. Positive rates of IgG were respectively 19.44%, 65.22% and 92.59% in 1~7 days, 8~14 days and 15~33 days after onset of fever, and there were remarkable difference among them. Conclusions Antibody IgM and IgG of Urbani SARS-associated coronavirus may occur at the early stage of illness in patientswith SARS, which positive cases may increase remarkably 2 weeks later after onset of fever. There may be recent infection and/or former infection of Chlamydiae P., Mycoplasma P., Adenovirus and RSV in some patients with infectious atypical pneumonia. Detection of Antibody IgM and IgG of Urbani SARS-associated coronavirus in sera with immune fluorescent technique can be used on the early diagnosis of SARS.

Objective To study the relationship between the low level lead exposure of pregnant woman and the gestational age of fetus. Methods The peripheral blood and the umbilical blood samples were collected from 1 000 healthy puerperants and their newborns. The puerperants were divided into three groups according to the blood lead levels: very low-level group(0.483 ?mol/L). Results The rate of premature labor was 9.40% in the very low-level group, 14.07% in the low-level group and 23.81% in the high-level group respectively. The blood lead level of puerperants had a positive correlation with the umbilical blood lead of newborns. The umbilical blood lead of premature was higher than that of mature. As the blood lead level of the pregnants increased, the gestational age shortened and the probability of low age premature increased. Conclusion As for the toxicity of lead to the fetus, there is no a threshold. Low level lead exposure of the pregnant woman is one of the causes of premature labor.

Objective To define the role of HCV-specific cytotoxic T lymphocytes (CTL) in chro-nic hepatitis C virus (HCV) infection. Methods HCV-specific CTL activity (HCV-CTL) was assessed in the liver and peripheral blood cells in 62 patients with chronic hepatitis C and 8 non-HCV-infection controls by using bulk-expanded liver/peripheral blood mononuclear lymphocytes (PBMC)-derived CD8+ cells as effector cells, EBV-transformed B cells as autologous target cells and recombinant vaccinia vectors expressing various regions of the HCV genome as transduction vector, in a standard chromium release assay. Results HCV-CTL activity was detected from the liver in 28 of the 60 patients (46.7%), but not from PBMC. CTL activity could not be detected from the liver and PBMC in all non-HCV-infection controls. Five patients with non-type 1 HCV infection were found to have HCV-specific CTL activity against HCV type 1 epitope. Compared with the patients without detectable HCV-specific CTL activity based on our assay, those exhibiting CTL activity had higher serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, higher histologic activity indices and lower levels of HCV RNA (all P
