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.

Objective Epicardial fat volume ( EFV) was a risk factor for coronary heart disease ( CHD) , but there is little research regarding the relationship of EFV with insulin resistance ( IR) and CHD in patients with metabolic syndrome ( MS) .The aim of the article was to explore the effect of EFV in patients with MS on CHD and IR . Methods Patients with MS treated by percutane-ous coronary angiography ( CAG) in our hospital from February 2013 to August 2013 were recruited in this study .The data of height , weight, waist circumference(WC) and hip circumference(HP) were recorded.EFV were measured by MSCT.Fasting blood samples were collected for blood biochemical test . Results EFV in patients with MS was in positive relation with IR index (IRI)(r=0.335, P<0.001) and CHD (r=0.321, P<0.05), and the correlation still remained when the influences of WC and body mass index (BMI) were excluded.Logistic regression analysis showed that EFV was an independent risk factor for CHD (P<0.05), while linear regression analysis indicated EFV , BMI and LDL-C were the risk factors for IRI .ROC curves analysis proved EFV and BMI had diag-nosis value for IRI, and the areas under curve of EFV were 0.755 and 0.679 (P<0.05) respectively. Conclusion EFV is an in-dependent risk factor for CHD and IRI in patients with MS , and EFV has an advantage over BMI in the diagnosis value of IRI .
