Objective To observe the change of six cytokines in mice infected with Echinococcus multilocularis as part of the study on immunological mechanism in the infection. Methods Mice were infected by abdominal inoculation of echinococcus protoscoleces. The change of serum level of the cytokines IL-2、IFN-?、TNF-?、IL-4、 IL-5 and IL-10 was determined by ELISA during the infection which lasted for 260 d. Results Compared with uninfected control, the levels of the cytokines all significantly increased in the 260 d. The level of IL-2 reached a peak after 80 d post-infection (p.i.), then decreased quickly after 140 d p.i., High level of TNF-? was detected after 40 d, compared to uninfected control, reached a peak at 100 d p.i., and decreased quickly after 140 d. The level of IFN-? reached a peak after 80 d p.i., and decreased slowly after 140 d p.i., The levels of IL-4, IL-5 and IL-10 remained lower before 80 d, and increased sharply after 100 days. The levels of IL-4 and IL-10 reached peaks at 100 d p.i., and that of IL-5 at 140 d p.i. Conclusion The data suggest that the induction of Th2 antibody-mediated immunity (AMI) with a parallel expansion of Th1 cell-mediated inflammatory (CMI) responses are important mechanism of the host in defending against the metacestodes. Th1 CMI plays an important role at the early stage of infection, and Th2 AMI is important in the later stage of infection.

Immunology teaching course includes both basic immunology and clinical im-munology.This paper points out the problems of teaching and knowledge integration between the basic immunology and clinical immunology and suggests that teaching team should include the basic immunology and clinical immunology related content clinical experts to promote teaching quality.

Objective: To study the expression of PDCD5 mRNA and its significance in esophageal cancer in Xinjiang Kazakh and Han nationality. Methods: RT-PCR was used to detect the mRNA of PDCD5 in 40 cases of esophageal cancer (18 cases of Kazakh, 22 cases of Han). Results: The positive rate of PDCD5 mRNA expression in 40 samples of esopha-geal cancer tissue, adjacent tissue, and normal tissue was 80.0% (32/40), 80.0% (32/40) and 87.5% (35/40), respectively, with no significant difference (P>0.05). The Ods of cancer tissues, adjacent tissues, and normal tissues were 0.7644± 0.1444, 0.9341 ±0.1631 and 1.8703±0.4767, respectively. The expression of PDCD5 was significantly increased in cancer tissues compared with that in normal tissues (P<0.05). The expression level of PDCD5 mRNA was not significantly correlat-ed with the degree of differentiation and lymph node metastasis. Conclusion: No significant difference was found in PDCD5 mRNA expression in esophageal cancer between Xinjiang kazakh and Han nationality (P>0.05). The expression of PDCD5 is not correlated with the degree of differentiation, depth of invasion or lymph node metastasis. Detection of PDCD5 mRNA expression in esophageal cancer tissues may provide valuable information for patient prognosis.

Objective:To investigate the changes of sTim-3,HMGB1 and TGF-β in the brucellosis patients and to analyse the relationship between the changes of these molecules and brucella infection. Methods:28 cases of brucellosis patient untreated and 28 healthy control cases in the age and gender matched with brucellosis cases were collected. The serum levels of sTim-3 and HMGB1 were detected by ELISA,and the levels of Spot forming cells secreting TGF-β were measured by ELISPOT in patients and healthy control group. Results: Compared with healthy controls, sTim-3/HMGB1 expression levels and Spot forming cells secreting TGF-β were significantly increased in the brucellosis patients ( P<0. 01 ) . The changes of Spot forming cells secreting TGF-β were positively correlated with the levels of HMGB1 (P<0. 05). Conclusion:The serum levels of sTim-3/HMGB1 and Spot forming cells of secreting TGF-β from peripheral blood mononuclear cell are significantly increased in the brucellosis patients. Those molecules may be involved in the process of brucella infection and may play a significant role in the immune escape of patients infected with brucella.
