Objective To evaluate and compare the cellular immune response induced by live at-tenuated and inactivated hepatitis A vaccines. Methods A total of 18 healthy volunteers were enrolled in this study. They were divided randomly into 2 groups and injected by inactivated hepatitis A vaccine and at-tenuated hepatitis A vaccine, respectively. All volunteers' heparinized venous blood was separately collected for testing anti-HAV antibody and the responses of PBMC. The level of IFN-γsecreted by effect T cell was tested by ELISPOT. The percentage of lymphocytes secreting IFN-γ from CD+ and CD8+ T cell was tested by intracellular cytokine staining (ICS) technique. The concentrations of IFN-γ, IL-2, IL-10 and IL-4 in the culture supernatants(grown in the presence or absence of HAV) of the in vitro HAV-primed PBMC were determined by Luminex. Results These two types of vaccines can elicit specific anti-HAY antibodies and no statistical significance between them were observed. At the early stage after inoculation, T cell-mediated immune responses with the secretion of IFN-γ were detected in vaccines inoculated with either type of vac-cines. There was a tendency that the cellular immune responses level induced by inactivated hepatitis A vac-cine was higher than that by live attenuated hepatitis A vaccine during 1 to 3 weeks post-injection. The booster inoculation could significantly increase the level of cellular immune responses induced by the inacti-vated vaccine. Conclusion Both live attenuated and inactivated HAV vaccines can elicit an earlier specific humoral and cellular immune responses, and booster inoculation of inactivated HAV vaccine can rapidly and intensively evoke memory immune responses.

Objective To assess these in a consecutive series of patients with ICC treated surgically. Methods A retrospective study was conducted on 189 ICC patients undergoing surgery.Surgical results and survival were evaluated and compared among different subgroups of patients.Univariate and multivariate analyses were performed to identify prognostic factors.Results R0,R1,R2 resection and exploratory laparotomy were obtained in 63,84,31 and 11 patients,respectively.The overall 5 -year survival rates for the entire cohort were 16.8%,with corresponding rates of 26.3% for patients with R0 resection;14.3% for patients with R1 resection;6.8% for patients with R2 resection;and 0.0% for patients with an exploratory laparotomy.Independent factors for poor survival included positive resection margin,multiple tumors,beta - catenin nuclear expression and lymph node metastasis. Conclusion R0 resection offers the best possibility of long -term survival,but the chance of a R0 resection is low when surgery is performed for potential resectable ICC.Patients with characteristics of beta -catenin nuclear expres-sion,multiple tumors and lymph node metastasis are indicated to surgery which is needed to be further studied.

OBJECTIVE To study the isolation rate of Acinetobacter baumannii, characteristics of infection distribution and antimicrobial resistance rates. METHODS Surveillance data of A. baumannii infection of wards, its distribution and resistance rates to 20 kinds of antibiotics in our hospital for 5 years were analyzed . RESULTS During the 5-year infection surveillance, 523 strains of A. baumannii were isolated in our hospital mostly from sputum. The commonest site was lower respiratory tract. The ward with the highest incidence of A. baumannii infection was ICU. The isolation rate was 11.1% in 2004, though 3.9% in 2000. A. baumannii was resistant to 20 kinds of antibiotics, especially to imipenem, cefoperazone /sulbactam and ampicillin/sulbactam. CONCLUSIONS The isolation rate of A. baumannii and antimicrobial resistance rate are increasing year by year. The increased rate of multidrug-resistance should be payed more attention .
