Objective: To determine the changes of fatty acids composition of eel oil after refining processes. Methods: The composition of fatty acids was determined by GC-MS. Results: The purity of eel oil was increased and the content of high-unsaturated fatty acids was not influenced after deodorization by water vapor distillation at 180 ℃ and 0.01 MPa. Its nutritive value was increased, while its purity and content of unsaturated fatty acids were further increased after winterization at 10 ℃. Its quality, especially unsaturated fatty acids, distinctly decreased after water vapor distillation at 227 ℃ and 0.01 MPa.Conclusion: The nutritive value of eel oil is increased after refining processes of water vapor distillation at 180 ℃ and 0.01 MPa, and winterization at 10 ℃.

OBJECTIVE:To investigate the characteristics of adverse drug reactions (ADR) caused by quinolones in our hospital and to promote their rational use in clinic. METHODS: By a retrospective review,a total of 199 quinolones-induced ADR cases collected from May 2004 to December 2007 in our hospital were analyzed statistically in respect of patients' gender and age,drug species involved,past ADR history,route of administration,clinic manifestations,etc. RESULTS: A total of 9 kinds of quinolones involved in the 199 ADR cases,of which,118 cases were induced by levofloxacin,16.1% had past ADR history,93.5% of the ADR cases were induced via intravenous drip,and most common presentations of the ADR were lesions of skin and its appendants as well as digestive system. There were 7 serious ADR cases. CONCLUSION: The indications of quinolones should be controlled strictly,which should be preferably administered orally and monitoring of its administration should be emphasized in clinical practice to decrease and avoid the occurrence of ADR.

OBJECTIVE:To assess the stability of the quality control of FPIA for monitoring of CsA and MEIA for monitoring of FK506.METHODS:The quality control on the blood samples of patients receiving therapeutic drug monitoring of CsA and FK506 from June to August in 2007 were subjected to a continual assessment and analysis to investigate the stability and accuracy of the quality control.RESULTS:The mean recoveries of the low,middle and high concentrations of CsA and FK506 were 93.14%～97.65% and 97.70%～103.09% respectively,with RSD at 4.41%～5.37% and 10.44%～14.23% respectively,which accorded with the requirement for biological sample determination stated in the Chinese Pharmacopoeia.CONCLUSION:The methods of FPIA for monitoring of CsA and MEIA for monitoring of FK506 were accurate,and worth to be applied in clinical to guide individualized medication.

AIM: To investigate the effects and mechanisms of swainsonine-induced apoptosis on SGC-7901 cells. METHODES: After being treated with swainsonine, effective dose and median inhibition concentration (IC50) of swainsonine to SGC-7901 cells were examined by MTT assay. Cell cycle distribution and apoptotic rates were analyzed by flow cytometry. Expression of p53, c-myc and Bcl-2 were determined by immunocyto- chemical method, and the concentration of Ca2+ intra-cellular ([Ca2+]i ) was measured by the laser scanning confocal microscope (LSCM). RESULTS: Swainsonine inhibited cell growth of SGC-7901 in vitro, IC50 of 24 h was 0.84 μg·ml-l, and complete inhibition concentration of swainsonine was 6.2 μg·ml-l. Treated with swainsonine at the concentrations of 0.5, 1.5 and 4.5 μg·ml-l for 24 h, the expression of apoptosis inhibiting gene p53 and bcl-2 decreased, and apoptotic trigger gene c-myc increased (P<0.05), as well as [Ca2+]i overloading, SGC-7901 cell was induced to apoptosis in the end. The percentage of S phase were 38.8%, 39.7% and 29.6%, respectively (20.0% in control group and 23.2% in 5-Fu group), the percentage of G2/M phase were 4.5%, 1.7% and 5.3%, respectively (5.5% in control group and 9.0% in 5-Fu group), and the percentage of G1/M phase was not altered. SGC-7901 cells were treated by swainsonine at the concentrations of 0.5, 1.5 and 4.5 μg·ml-l for 24 h. Compared with the control group, the percentage of S phase were increased and that of G2/M cells were decreased significantly in treatment groups (P<0.01). CONCLUSION: Swainsonine can inhibit the cell proliferation and induce apoptosis of SGC-7901 cells, the mechanisms of swainsonine-induced apoptosis may related with [Ca2+]i overloading and expression of apoptosis-related genes.

Objective To investigate changes in the expression of prepro-orexin and orexin receptor-1 ( OX1R) following permanent middle cerebral artery occlusion ( MCAO ) with or without preconditioning through electrical stimulation of the cerebellar fastigial nucleus (FNS). Methods Wistar rats were subjected to permanent MCAO and randomly divided into 5 groups: a sham-operated control group (PO), an FNS preconditioning + shamoperated control group (FNS-PO) , an ischemia group, an FNS preconditioning + ischemia group (FNS-PI) and a cerebellar fastigial nucleus injury + FNS preconditioning + ischemia group (FNL-FNS-PI). Each group was divided into 5 subgroups according to the time at which the animals were sacrificed after the MCAO ( 1, 3, 6, 12 and 24 h).RT-PCR was used to detect expression of OX1R mRNA, and ELISA to measure the levels of orexin-A in the hypothalamus and plasma. Results The immunoreactivity of prepro-orexin decreased significantly in the PI groups, with further decreases over time. At the 12th h after MCAO, the immunoreactivity of prepro-orexin reached a minimum.There were significant differences between the rats in the PO and FNS-PO groups. On the contrary, the immunoreactivity of OX1R increased significantly in the PI groups, with further increases continuing over time, peaking at 12 h after the MCAO. There were significant differences between the PO and FNS-PO groups. In the rats with FNS preconditioning (PI-FNS) , the decrease in prepro-orexin and the increase in OX1R were significantly inhibited compared to the PI subgroups at the 6th and 12th hour. There was no significant difference between the FNL-PIFNS group and the PI group. The expression of OX1R mRNA increased significantly in the PI group, with further increases continuing over time, peaking at 24 hours. The plasma levels of orexin-A were not significantly different among the groups, but the levels of orexin-A in the hypothalamus decreased significantly in the PI and FNL-PI-FNS groups, with further decreases continuing over time. At the 12th h after the MCAO the levels were significantly different compared with the PO and PO-FNS groups. While in the rats with FNS preconditioning (PI-FNS) , the decrease in orexin-A level was reversed and there was no significant difference compared with PO and PO-FNS groups. Conclusions The orexinergic system is altered following cerebral ischaemia. FNS preconditioning may be able to regulate these changes.
