ObjectiveTo study the relevant effect of proinflammatory cytokines interelenkin-17(IL-17), -6 and endothelin-1 (ET-1) on statins attenuating no-reflow phenomenon after myocardial ischemia-reperfusion in rats.MethodsEighteen healthy male Wistar rats were randomly divided into 3 groups according to body weight: sham operation, injury, preconditioning groups. The preconditioning group was given atorvastatin 2 mg·kg-1 ·d-1 and the other two groups were given the same volume of saline once. After 7 days, the rats were anesthetized with an intraperitoneal injection of chloral hydrate, and then the thoracic cavity was opened. The coronary artery of injury group and preconditioning group were ligated for 60 minutes, and then opened for 15 minutes, to establish the rat acute myocardial ischemia-reperfusion model. The sham operation group was was treated with a seam through the coronary artery without ligation. Eleetrocardiogram was checked before ligation, and ligation was carried out for 15, 30, 45 minutes and then reperfusion for 15 minutes. After reperfusion for 15 minutes, the thioflavine S and Even's were injected from femoral venous, then the heart and blood were obtained(keeping left ventricular only). Hearts were flushed with saline and sliced transversely into five to seven sections. Finally, observed at 365 nm wave length the existence of non-fluorescent areas, which was no-reflow zone. The level of serum IL-17, IL-6 and ET-1 was detected by ELISA. Results The electrocardiogram confirmed that the sham operation group had no ischemic damage and the model of myocardial ischemia- reperfusion was established in preconditioning group and injury group. The noreflow phenomenon could be observed under 365 nm wave length in preconditioning group and injury group. The ligated area[LA%, (57.34 ± 11.49)%, (53.08 ± 8.66)%] of injury group and preconditioning group was higher than that of sham operation group(0, all P < 0.05); the area of no-reflow[ANF%, (48.96 ± 6.94)%, (21.37 ±3.35)%] of injury group and preconditioning group was higher than that of sham operation group(0, all P < 0.05),and the ANF% of preconditioning group was lower than that of injury group(P < 0.05) ; the level of serum IL-17,IL-6 and ET-1[(151.67 ± 11.19) × 10-9, (167.89 ± 5.13) × 10-9, (322.37 ± 19.08) × 10-9 g/L] of injury group was higher than those of sham group and preconditioning operation group[(49.75 ± 14.06) × 10-9, (59.32 ± 5.26) ×10-9, (109.9 ± 12.12) × 10-9, (90.45 ± 11.63) × 10-9, (112.47 ± 10.40) × 10-9 and(198.91 ± 27.88) × 10-9 g/L,P < 0.05], the level of serum IL-17, IL-6 and ET-1 of preconditioning group was higher than those of sham operation group(P< 0.05). Conclusionsno-reflow phenomenon is related with IL-17 and ET-1 which can promote the expression of IL-6, statins decreases the expression of IL-17 and ET-1, and then decreases the on-reflow phenomenon.

Objective To construct transgenic mice tissue-specifically co-expressing human DAF/CD59 in the vascular endothelia and to investigate the ability to protect against human comple- ment-mediated attack.Methods Transgenic mice were generated by co-microinjection of hDAF/CD59 expression constructs driven by the human intercellular adhesion molecule-2(ICAM-2)promoter.PCR and Southern blot of genomic DNA were used to assess the presence of hDAF/CD59 in the genome of the founders,and the expression at protein level was measured by flow cytometry.Immunohistochemis- try was used to detect the distribution of hDAF/CD59.An ex vivo perfusion model was used to com- pare hearts from these hDAF/CD59 transgenic mice with hDAF hearts.Results After microinjection of genes,11 of 135 mice born were shown to be double-transgenic,and human DAF/CD59 were ex- pressed on the surface of leucocytes in 6 of the 11 DAF/CD59-integrated mice.Expression levels of 6 founders ranged from 80% to 95% of that in human leucocytes.Human DAF/CD59 were strongly expressed in the vascular endothelia of heart,kidney,with little or no positive staining observed in non- endothelial cells.Compared to hDAF hearts that maintained approximately 20% maximum work during perfusion with 20% human plasma,these endothelial-specific hDAF/CD59 hearts were further protected with work maintained at 40% of the maximum level during 60 min.Conclusion The intro- duced hDAF/CD59 genes have been integrated and specifically expressed in the vascular endothelia. The endothelial co-expression of hDAF/CD59 can provide greater protection against human complement-mediated attack than the expression of hDAF alone.

AIMTo determine clonidine in rabbit plasma by LC-MS.
METHODSThe LC-MS system consisted of Waters Alliance 2790 HPLC and Micromass ZQ-4000 MS. The HPLC was performed by using XTerra C18 (150 mm x 2.1 mm ID, 5 microm). The mobile phase, consisting of acetonitrile/ammonium hydrogen carbonate solution, was maintained to a flow-rate of 0.2 mL x min(-1) and the linear gradient elution was adopted. Mass spectrum was obtained by using electrospray ionization interface and the m/z of SIM was 230.
RESULTSThe average recovery was high and the method was reproducible. The calibration curve showed good linearity in the range of 1 - 80 microg x L(-1), the lowest limit of detection was 0.05 microg x L(-1). The Cmax, AUC0-t, and Tmax value of the pharmacokinetics parameter were (27 +/- 9) microg x L(-1), (5,352 +/- 1,121) microg x L(-1), (79 +/- 17) h.
CONCLUSIONThe results demonstrated that the method had high sensitivity, good selectivity, accuracy and precision. It is used to determine the clonidine concentration in plasma. The transdermal patch can deliver clonidine to the surface of rabbit skin stably for periods of up to 1 week after a single application.
