This study was aimed to investigate the induction effect ofRe-Du-Ning (RDN) Injection on rat liver microsome CYP450 enzymes. SD rats were randomly divided into the solvent control group, positive control group as well as the low, middle and high dose group of RDN (1, 2, 4 mL·kg-1·d-1). After drugs were administrated continuously for 7 days, the rats were sacrificed. The liver was weighed and prepared to microsomes. Meanwhile, the liver coefficients of rats were calculated. And the protein content was detected by BCA method. Finally, activities of five important subtypes of CYP450 enzymes such as CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A1/2 were measured by the“cocktail” method. The results showed that the levels of liver coefficients, microsome yield rate and activities of CYP450 subtypes increased significantly in the positive control group compared with the solvent control group (P < 0.01). There was no significant difference on the levels of liver coefficients, microsome yield and protein content between the low and middle dose group of RDN. However, there was significant difference on the levels of liver coefficients and microsome yield in the high dose group (P < 0.05). In terms of the influence on enzyme activity, RDN Injection can significantly induce the activities of CYP1A2 with dose dependence. It can induce the activities of CYP2C9 and CYP2C19 at the middle and high dose. However, there was no obvious influence on the activities of CYP3A1/2 and CYP2D6. It was concluded that the positive control group can obviously induce activities of CYP450, which can be used in the evaluation of induction experiments. RDN Injection had induction effect on CYP1A2, CYP2C9 and CYP2C19. But it had no influence on the activities of CYP3A1/2 and CYP2D6.

Objective To explore the expression and change of ski-interacting protein (SKIP) in rats after spinal cord injury. Methods A total of 60 adult female Sprague-Dawley rats were randomly divided into sham group (n=30) and spinal cord injury (SCI) group (n=30), each group was further divided into five time points including one day, three days, five days, seven days, and 14 days with six rats in each time points. The model was established at T10 with modified Allen's technique, and the sham group only bit the lamina of rats. The hindlimbs behavior was assessed with Basso-Beattie-Bresnahan (BBB) score at each time point. The pathological changes of spinal cord neurons were detected with Nissl staining. The expression of SKIP were observed with immunofluorescence staining. Results The BBB scores were signif-icantly lower in each time point in SCI group than in the sham group (t>48.267, P<0.001). Compared with the sham group, Nissl bodies in the cytoplasm of spinal cord neurons began to disintegrate, coalesce and irregularly distribute, the neurons began to degenerate and die on the fifth day, and the damage deteriorated on the 14th day. Immunofluorescence staining showed that SKIP expression was mainly expressed in the gray matter of the spinal cord and little expressed in the white matter. The expression of SKIP gradually increased after SCI, and reached a peak on the fifth day (t=-17.035, P<0.001) and decreased significantly on the 14th day (t=3.853, P<0.05). Conclusion SKIP may be a new signaling molecule, which play an important role in neuronal apoptosis after SCI.
