Objective To explore the role of granzyme B( GzmB) in infiltrated myocardial cells of mice with viral myocarditis( VMC) induced by coxsackievirus B3(CVB3) during the injury of myocardium and further to elucidate the pathogenesis of VMC. Methods Thirty-six BALB/c male mice, 5 to 6 weeks old, were randomly divided into two groups: the normal group, 10, and the model group, 26. On the eleventh day all mice were killed and the hearts were taken out for inspection whether there were pathological changes in the myocardium by macroscopy and microscopy. The expression of GzmB was detected in myocardium with immunohistochemistry and hemi-quantitive reverse transcript-polymerase chain reaction ( RT-PCR). Results GzmB positive cells in the mice myocardial cells infiltrated were detected by immunohistochemistry in the model group,and the number of GzmB positive cells is remarkable positive correlation to myocardial pathological score(r =0. 859, P =0.000) , however, no such cells were discovered in the normal murine hearts. Test of RT-PCR showed markedly high expression of GzmB mRNA in mice myocardium of the model group, however, no expression of GzmB mRNA in the normal group. Conclusion The expression of GzmB in the infiltrating myocardiocytes probably plays some role during the injury of myocardium, which mediated cytotoxicity effect is one of important mechanisms of myocardial injury in viral myocarditis. The expression quantity of GzmB in the infiltrating myocardiocytes is significant positive correlation to the severity of myocardial injury.

OBJECTIVE: To investigate part mechanisms of Th cell differentiation, and to observe the interference effect of Qingxin-II Recipe in the chronic stage of viral myocarditis (VMC), so as to provide some experimental evidences for illuminating the pathogenesis of VMC and treatment mechanisms of Qingxin-II Recipe. METHODS: According to 20%-40% death rate of experiment in advance, 100 BALB/c male mice (4 weeks old and weighing 12-15 g) were used. Twenty mice were randomly assigned to normal control group, and the other 80 mice were intraperitoneally injected with 0.1 ml normal saline containing coxsackie virus B3 at the 1st, 4th and 28th day (the virus densities were 1:2000, 1:1000 and 1:500 respectively) to induce chronic VMC. At the 42nd day, the surviving mice were randomly divided into untreated group and treatment group, with 20 mice in each group. Mice in the treatment group were orally administered with 0.2 ml Qingxin-II Recipe every day, while mice in the normal control group and the untreated group were administered with 0.2 ml normal saline. All the mice were sacrificed after 45 days, and the sera, heart and spleen cells were collected. Then the myocardial pathological changes were observed by using a light microscope, and the levels of IL-4, IL-10 and IFN-gamma in serum were detected by enzyme linked immunosorbent assay (ELISA). And the Th cell differentiation was observed by flow cytometry. RESULTS: No obvious myocardial pathological changes were observed in mice of the normal control group. Myocardial pathological changes in the treatment group were slighter than those in the untreated group. The difference of serum IL-10 level between the normal control group and the untreated group showed no significance (P>0.05), and the levels of IFN-gamma and IL-4 of the untreated group were higher than those of the normal control group (P<0.05 or P<0.01). There was no statistical difference in IL-10 level between the treatment group and the untreated group (P>0.05), while the serum levels of IL-4 and IFN-gamma of the treatment group were lower than those of the untreated group (P<0.05 or P<0.01). There was no significant difference of the Th1 cell responder between the treatment group and the untreated group (P>0.05), while the Th2 cell responder was inhibited significantly in the treatment group (P<0.05). CONCLUSION: Qingxin-II Recipe can restore the balance of Thl and Th2 cells through inhibiting the reaction of Th2.
