Aim To study the effects of ferulic acid (FA) on E-selectin expression in human umbilical vein endothelial cells (HUVECs) activated by lipopolysaccharide and leukocyte-endothelial cell adhesion. Methods The effects of FA on E-selectin and E-selectin mRNA expression were determined by flow cytometry and reverse transcription polymerase chain reaction. The effect of FA on HL60-HUVEC adhesion was evaluated with the method of staining the cells by Rose Bengal. Results The expression of tively). Conclusion FA can inhibit the expression of E-selectin and E-selectin mRNA and HL60-HUVEC adhesion. This may contribute to its protective effect against ischemia-reperfusion injury.

Purpose The aim is to isolate and purify Protein C(PC) and Protein S(PS) from no-albumin human plasma by rivanol precipitation. Methods The isolated and purified steps included adsorption onto and elution from barium, salting-out, ion-exchange chromatography, affinity chromatography,preparative isoelectric focusing and so on. Results The molecular weights of the obtained PC and PS were (61±0.9)kD and (83±0.8)kD, respectively, the isoelectric point, 4.70±0.03 and 5.20±0.03,and the yield, 28.3% and 12.6%. The purified PC and PS were shown to be highly homogeneous by capillary zone-electrophoresis(CZE), and rich in Glu, Leu and Gly or Asp, Glu and Leu respectively. Conclusion The methods could be used for large-scale isolation and purification of PC and PS from no-albumin human plasma.

AIM: To investigate the therapeutic action of secreted endostatin (ES) on breast cancer cells. METHODS: Retroviral-mediated endostatin gene was transferred to breast cancer cell line MDA-MB-231. The ES biological properties and function were evaluated by polymerase chain reaction (PCR), MTT and a murine xenograft model. RESULTS: After retroviral transduction, endostatin genetically modified breast tumor cells were confirmed by PCR, and the integration and durative expression of endostatin gene was successfully committed. Compared with controls, endostatin secreted by genetically modified cells markedly inhibited endothelial cell proliferation (P0.05). The results of the transplanted subcutaneous tumor model in nude mice suggested that the subcutaneous growth of MDA-MB-231 was significantly inhibited by the expression of endostatin gene (P

Objective To explore the effects of astrocytes on the N-ethylmaleimide-sensitive fusion protin,(NSF) and AMPA receptor of the neurons as well as their function in epileptogenesis. Methods ACM was injected into lateral ventricle of SD rats and the behaviour changes were observed; Immunohistochemical method was used to assess the changes of the expression of NSF in the cerebral cortex and hippocampus; The cultured neurons were divided into control group, ACM group and CNQX+ACM group at random, immunocytochemistry was used to assess the changes of the expression of NSF, Western blotting was used to assess the changes of the content of NSF of the cultured neurons. Results Seizure was observed in ACM group 30 min after injecting ACM. the immunoreaction of NSF in hippocampus and cerebral cortex of rats were depressed than those of the control group 2h, 4h after injecting ACM (P

To explore the effect of coriaria lactone (CL)-activated astrocyte-conditioned medium on the cerebral TNF-alpha of normal rats, the CL-activated astrocyte-conditioned medium (ACM) was injected into the lateral ventricle of SD rats. The rats were observed for behavioral changes, and the changes of the expression of TNF-alpha in the cerebral cortex and hippocampus were immunohistochemically examined by employing SP method. TNF-alpha level was assessed by means of radioimmunoassay in homogenate of cerebral cortex and hippocampus as well as cerebrospinal fluid. Seizure episodes were observed in ACM group 30 min after the ACM injection, but they were not observed in the control group. Immunohistochemical detection showed that the immunoreaction of TNF-alpha in hippocampus and cerebral cortex of rats were stronger than that of the control group 4 h after the ACM injection (P<0. 05). In this group, the concentrations of TNF-alpha in homogenate of cerebral cortex and hippocampus and cerebrospinal fluid were higher than those of the control group (P<0.05). It is suggested that the ACM activated by CL can enhance the expression of TNF-alpha in normal rats, and is related to epileptogenesis.

To explore the roles of astrocytes in the epileptogenesis, astrocytes and neurons were isolated, purified and cultured in vitro from cerebral cortex of rats. The astrocytes were activated by ciliary neurotrophic factor (CNTF) and astrocytic conditioned medium (ACM) was collected to treat neurons for 4, 8 and 12 h. By using Western blot, the expression of calmodulin dependent protein kinase II (CaMK II), inducible nitric oxide synthase (iNOS) and adenylate cyclase (AC) was detected in neurons. The results showed that the expression of CaMK II, iNOS and AC was increased significantly in the neurons treated with ACM from 4 h to 12 h (P<0.05), and that of iNOS and AC peaked at 8 h and 12 h respectively. It was suggested that there might be some epileptogenic factors in the ACM and such signal pathways as NOS-NO-cGMP, Ca2+/CaM-CaMK II and AC-cAMP-PKA might take part in the signal transduction of epileptogenesis.
