Objective To establish an animal model of human rotavirus(HRV)-induced diarrhea. Methods Sixty ICR suckling mice were randomly divided into two groups, and each was further divided into 3 subgroups(A, B, C for group Ⅰ, and D, E, F for group Ⅱ);group B, C, E and F were assigned as experimental groups. while group A and D were controls. Mice in group B and C were inoculated with3 × 10~5 PFU and 3×10~6 PFU HRV Wa strain fluid respectively when they were 4-day old. Mice in group E and F were inoculated with 3×10~5 PFU and 3×10~6 PFU HRV Wa strain fluid respectively when they were10-day old. The symptoms, fecal viral excretion, intestinal histopathologies and ultrastructures of animals were observed. One-way ANOVA was used to compare the differences among the groups. Results There were significant differences in the duration of diarrhea and viral excretion, jejunal villous height, the weight at d4 and d7 after inoculation among three subgroups in group Ⅰ(F=204.38, 86.60, 7.18, 18.41 and10.08, P<0.01). Diarrhea was not observed in group Ⅱ, and the differences in jejunal villous height and the weight at d4 and d7 after inoculation among three subgroups were not significant(F=0.16, 0.13 and 1.03, P>0.05). Compared with the group D, the duration of viral excretion was longer in group E and F(F=8. 34, P<0.01). Conclusion Animal model of HRV diarrhea can be established in 4-day-old ICR suckling mice infected with 3×10~6PFU HRV.

Objective To investigate the effects of CpG oligodeoxynucleotide (ODN) on cellular immune responses in suckling mice infected with human rotavirus (HRV). Methods Forty ICR suckling mice were randomly divided into four groups: control group. HRV infection group, CpG ODN pretreatment group and CpG ODN treatment group. Suckling mice were sacrificed four days after rotavirus challenge. Small intestine and spleen samples were collected under sterile condition. Thedegree of small intestinal mucosal injures was evaluated with standard scoring criteria. The spleen index was calculated and spleen lymphocyte stimulation index was detected by methyl thiazolyl tetrazolium ( MTT) assays. Levels of gamma interferon (IFN-γ), interleukin-4 ( IL-4) in the supernatant of spleen lymphocyte culture were detected by enzyme linked immunosorbent assay (ELISA). T lymphocyte subsets were analyzed by flow cytometry. The data was compared by one way ANOVA. Results The scores of mucosal injures of mice in HRV infection group, CpG ODN pretreatment group and CpG ODN treatment group were 4. 00 ±1. 31, 2. 75 ±1. 28 and 2. 87 ±0. 99, respectively, and the differences among groups were statistically significant (F=ll. 32,P＜0. 01). The scores of mucosal injures in CpG ODN pretreatment group and CpG ODN treatment group were both lower than that in HRV infection group (P＜0. 05). Compared with control group, spleen lymphocyte stimulation index and the percentage of CD8+ T lymphocytes were higher, the percentage of CD4+ T lymphocyte and ratio of CD4+ /CD8+ T cells were lower, levels of T helper (Th)1 type cytokine IFN-y increased significantly in HRV infection group; while the spleen index, spleen lymphocyte stimulation index, percentages of CD4+ and CD8+ T lymphocytes, IFN-y levels were all increased in CpG ODN pretreatment group and CpG ODN treatment group (P＜0. 05). The spleen index, spleen lymphocyte stimulation index, the percentage of CD4+ T lymphocytes, CD4+/CD8+ ratios and IFN-y levels in CpG ODN pretreatment group and CpG ODN treatment group were all significantly higher than HRV infection group (P＜0. 05). Conclusion CpG ODN potently enhances cellular immune responses in ICR suckling mice infected with HRV and CpG ODN could induce dominant Th1 response.

AIM: To observe the effect of hypoxia on cardiaomyocytes apoptosis and the role of ALDH2 in the process. METHODS: Cultured cardiomyocytes of neonatal rats were used. Hypoxia was imposed to the cardiomyocytes with or without daidzin pretreatment. ALDH2 activity was measured by the method of acetaldehyde metabolism. Apoptosis was measured by Hoechest 33324 staining, fluorescence activated cell sorting (FACS) and the DeadEnd~ TM fluorometric TUNEL system. RESULTS: ALHD2 enzyme activity in myocytes was inhibited by daidzin (24 h, 60 ?mol/L) without induction of apoptosis. When exposed to hypoxia, however, the apoptisis was significantly increased in the cells pretreated with daidzin compared to those without the pretreatment. CONCLUSION: The reduction of ALDH2 activity might increase the susceptivity of myocytes to apoptosis following hypoxia, suggesting a protective role of ALDH2 in hypoxia-induced myocardial injury.
