To investigate the possible effects of cyclosporine A(CsA) on the T cell dependent liver injury induced by Concanavalin A (Con A) in Kunming mice,25 Kunming mice were randomly divided into five groups. Con A (doses of 10mg/kg, 20mg/kg and 40mg/kg) was administered via the tail vein to duplicate the liver injury as the ConA group; CsA subcutaneously injected twice at doses of 130mg/kg 15 hours and 1 hour respectively before ConA challenge constitutes the CsA group. Phosphate buffered saline (PBS) only served as the control group. Blood samples for tumor necrosis factor alpha (TNF ?) and alanine aminotransferase (ALT) measurement were obtained at 8 hours after ConA administration. Histopathological examination was also performed for liver tissue. The results showed that ConA induced specific liver injury in Kunming mice was successfully duplicated. CsA markedly protected the mice from Con A induced liver injury by comparing the levels of serum ALT(44?16U/L vs 341?52U/L, P

Objective To observe the effects of Zuogui Jiangtang Jieyu Formula (ZJJF) on the ability of learning and memory and the expressions of JNK, Bcl-2 and Bax in hippocampus in diabetic rats with depression; To explore the protective mechanism of hippocampal damage in diabetic rats with depression. Methods High-fat gavage combined with intravenous injection of STZ was used to establish the model of diabetic rats. 28 days of chronic stress was given continuously and diabetic rats complicated with depression were built successfully. Then rats were randomly divided into 6 groups, including normal, model, positive medicine, high-, medium-, and low-dose of ZJJF groups. After the last administration, Morris water maze was used to detect escape latency time;Western blot was used to disclose the protein expressions of JNK, Bcl-2 and Bax in rat hippocampaus;RT-PCR was used to test the gene expressions of JNK and Bcl-2 and Bax. Results Compared with the normal group, escape latency time in model rats was significant longer (P<0.01), the protein and gene expression of JNK and Bax in rat hippocampaus significantly increased, Bcl-2 was markedly decreased (P<0.05, P<0.01);Compared with the model group, escape latency time in positive medicine group and high-dose of ZJJF group was significant shorter (P<0.01), the protein and gene expressions of JNK and Bax significantly decreased, and Bcl-2 markedly increased (P<0.05, P<0.01). Conclusion ZJJF can significantly improve the ability of learning and memory in diabetic rats with depression, which might be associated with preventing neuronal apoptosis in hippocampus.

Objective To evaluate the role of 2B subunit-containing NMDA receptors ( NR2B) in the rostal anterior cingulate cortex ( rACC) in development of pain-related aversion in a rat model of bone cancer pain using siRNA technique. Methods Forty-five healthy male Wistar rats, weighing 220-250 g, were divided into 3 groups ( n=15 each) using a random number table method: normal saline blank control group ( group NS) , NR2B-siRNA lentivirus group ( group LV-NR2B) and pGC-FU-siRNA lentivirus group (group LV-NC). A total volume of MADB-106 cells 3μl (4. 8×109 cells∕ml) was inoculated into the bone marrow cavity of the right tibia of rats. At day 2 after inoculation, NR2B∕siRNA recombinant lentivirus 0. 2μl was injected into rACC in group LV-NR2B, and pGC-FU-siRNA negative recombinant lentivirus 0. 2μl was injected into rACC in group LV-NC. The mechanical paw withdrawal threshold ( MWT) was measured at 1 day before inoculation and 3, 7, 14 and 21 days after inoculation. Conditioned place avoidance test was performed at 1 day before inoculation and 14 days after inoculation, and the percentage of residence time in room A was calculated. The rats were sacrificed at 21 days after inoculation and the rACC was re-moved for detecting NR2B protein and mRNA expression by Western blot or real-time polymerase chain re-action. Results Compared with the baseline at 1 day before inoculation, the MWT was significantly de-creased at 7, 14 and 21 days after inoculation, and the percentage of residence time in room A was de-creased at 14 days after inoculation in NS and LV-NC groups (P<0. 05), and no significant change was found in the parameters mentioned above in LV-NR2B group (P>0. 05). Compared with group NS, the MWT was significantly increased at 14 and 21 days after inoculation, the percentage of residence time in room A was increased at 14 days after inoculation, and the expression of NR2B protein and mRNA was down-regulated in group LV-NR2B ( P<0. 05) , and no significant change was found in the parameters men-tioned above in group LV-NC (P>0. 05). Conclusion Up-regulated expression of NR2B in rACC is in-volved in development of pain-related aversion in a rat model of bone cancer pain.
