Chinese Pharmaceutical Journal 2013;48(14):1165-1169
OBJECTIVE: To investigate the effects of dexmedetomidine(Dex) preconditioning on neuroapoptosis in hippocampus induced by isoflurane and the expression of CRMP2 proteins in neonatal rats. METHODS: Sixty neonatal rats at postnatal day 7 were assigned randomly into control group, Dex preconditioning control group, isoflurane group and isoflurane with Dex preconditioning groups which at dose of 25, 50 and 75 μg·kg-1. Rats in groups of isoflurane or control were exposed 0.75% isoflurane or air for 6 h. Rats in groups of Dex preconditioning were injected intraperitoneally with different doses of Dex 20 min before exposure and rats in other groups were injected intraperitoneally with 150 μL saline. At the end of exposure, the hippocampus of some rats were separated and proteins expression of cleaved caspase-3, phospho-CRMP2 (p-CRMP2), CRMP2 were detected by Western blot (n=6); other rats were perfused and their brains were embedded by paraffin, the neuronal apoptosis in hippocampus CA1 was detected by TUNEL staining 2 h after exposure (n=4). RESULTS: The number of TUNEL positive cells in hippocampus CA1 of rats in isoflurane group was increased by 434.99% (P<0.001) when compared with control group, Dex at dose of 75 μg·kg-1 significantly inhibited the increase of isoflurane-induced TUNEL positive cells by 71.87% (P<0.001). The expression of cleaved caspase-3 protein in isoflurane group increased by 90.20% (P<0.001) compared with control group, while Dex at dose of 25, 50 and 75 μg·kg-1 reversed isoflurane-induced increase of cleaved caspase-3 by 30.54% and 53.71%(P<0.05)and 96.71% (P<0.001)separately. Isoflurane increase the ratio of p-CRMP2/CRMP2 in the hippocampus by 119.41% (P<0.001), and didn't influence the expression of CRMP2; while Dex at dose of 50 and 75 μg·kg-1 inhibited isoflurane-induced increase of p-CRMP2/CRMP2 ratio by 63.75% (P<0.01) and 77.70% (P<0.01) and increased the expression of CRMP2 by 44.30% (P<0.05) and 62.13% (P<0.01). CONCLUSION: Dex Attenuates isoflurane-induced neurodegeneration through inhibitory effect of hippocampal neuroapoptosis in neonatal rats, decrease the ratio of p-CRMP2/CRMP2 and increase the expression of CRMP2 may be one of the mechanisms for neuroprotection and this Conclusion may provide the theoretic foundation for reasonable selection of anaesthetics.

Objective To investigate the causes of fever in systemic lupus erythematosas (SLE)patients and identify the characteristics of the fever caused by SLE fever infection after steroid therapy.Methods From January 2002 to May 2007, 487 SLE hospitalized patients with fever were admitted and their data were retrospectively studied. The clinical manifestations and medications were followed up. A case control design was carried out to identify the differences between fever caused by lupus and infection. Results Among all the 487 patients, 265 had infection, 206 had fever that was caused by SLE per se, fever caused by both lupus and concurrent infection was confirmed in 8 patients, malignancy and miscellaneous were the causes of fever in 4 respectively. The most common sites of infection were respiratory tract (61.3%), skin and mucosa (10.9%) and central nervous system (9.1%). The main microorganisms isolated were bacteria (77.4%), fungi (13.5%) and virus (7.8%). Prednisene ≤ 100 mg/d could suppress fever caused by lupus in 81.0% patients, usually within 1 to 5 days. In the case control study, lower C3, C4 and CH50, anemia, lymphocytosis, higher immunoglobulin levels, elevated anti-dsDNA antibodies, elevated anti-nuclear antibodies and higher SLEDA1 score were associated with SLE fever. Long SLE duration, old age, elevated CRP levels,leukocytosis, neutrophilia, high accumulated doses of prednisone and ever use of immunosuppressive medications were factors associated with infection. Conclusion The fever of in-patient SLE patients is mainly caused by infections and disease flare. Moderate dose of steroid therapy is effective to control the fever caused by lupus flare. The fever caused by SLE has different clinical features and laboratory results when compared to that caused by infection although both responses to steroid therapy.

Objective To study the mechanism of FTY720 on type Ι diabetic rats. Methods The typeⅠdiabetes rat model was established by feeding male SD rats with high energy urea and injecting into the abdominal cavity with low dose cephalosporins (STZ, 30 mg/kg). In the following, the treated rats were divided into two groups: model group and FTY720 group. Another group of untreated rats was assigned as normal control group. FTY720 group was given 1 mg/kg FTY720, the normal control group and model group was given the equal amount of water. Results The cardiac function of FTY720 group was recovered markeyly. FTY720 activated the expression of vascular endothelial cells S1P1 , diabetes and reduced the expessions of S1P3 and PKCβ Ⅱand it restored the migration ability of diabetes cardiovascular endothelial cell , as well as the abnormally elevated cardiovascular endothelial cells induced by high sugar permeability. Conclusion The S1P1 and S1P3 cut is an important reaction pathway to the complications of diabetes and cardiovascular dysfunction. FTY720 may reduce the damage to core blood vessels caused by diabetes , and pathological angiogenesis which functionally depends on the PKCβⅡ signaling pathways. Therefore, FTY720 may provide a potential therapy for cardiovascular function impaired by diabetes.
