Objective To evaluate the inhibitory effect of valdecoxib on the growth of the cancer cell lines and involvement of COX-2 in this inhibition. Methods Western blotting and immunocytochemistry were used to detect the expression of COX-2. MTT assay was used to determine inhibitory effect of the drugs on the cell growth. The content of PGE_ 2 in cell medium was determined with PGE_ 2 ELISA kit. Results ①Clone 26 cells expressed high levels of COX-2, whereas BGC-823,HGC-27 and SK-OV-3 cell had no COX-2 expression. ②Valdecoxib inhibited the growth of BGC-823, HGC-27, SK-OV-3 and clone 26 cells, with a IC_ 50 of 110.7, 99.2, 113.3, 117.6 ?mol/L, respectively. ③The inhibitory effect of these drugs on BGC-823 and clone 26 cell was in the descending order of valdecoxib, SC-560 and indomethacin. ④PGE_ 2 did not antagonize the effect of valdecoxib, SC-560 and indomethacin on BGC-823 and clone 26 cells. ⑤The inhibitory effect of valdecoxib and indomethacin on the growth of clone 26 cells was not compatible with that on PGE_ 2 . Conclusion The inhibitory effect of valdecoxib on cell growth is not related to its effect on COX-2.

Aim To investigate the influences on the aortal structure of rats with long-term high fat forages diet.Methods 14 SD rats were divided into two groups:the control group and the test group. The test rats were fed with high fat forages.12 weeks later, the aortas of the rats were observed with a light microscope, transmission electron microscope(TEM) and scanning electron microscope (SEM).Results In the test group, the aortic tunica intima thickening, endotheliocyte injury and monocyte adhesion were found with a light microscope; the elastic lamina being broken and the smooth muscle cells proliferated. Under TEM, the endothelial cell membrane of the aorta in the test rats was destroyed and appeared to be worm-eclipsed shape.Mitochondria exhibited swelling,vacuole degeneration and its cristae was dissolved, broken or some disappeared.Rough endoplasmic reticula (RER) expanded. The endothelial cell spaces were enlarged and the cell junctions deformed. Monocytes adhering to the endothelial cell stretched out pseudopodia and intruded into the endothelial crevice and the subendothelial layer. Some basement membranes completely sloughed following with endothelial cell. ERE and ribosomes increased in smooth muscle cells. SEM observation showed that the endothelial cells became swelling and the surface of endothelial cell was worm-eclipsed or crater shape. There were deeper crevices between endothelial cells.Conclusions Long-term high fat forages diet can induce injury of the endothelium and elastic lamina, adhesion of the monocytes and its intrusion into endothelial layer and subendothelial layer, proliferation of the subendothelial layer and smooth muscle in the aorta of rats.

Aim To evaluate the effect and the mechanism of valdecoxib on Lewis cancer. Methods Western blot was used to detect the expression of VEGF, MMP-2, Bax, Bcl-2 and Caspase-3 in tumor tissue. Flow cytometry was used to observe the effect of valdecoxib on proliferation, apoptosis and the cell cycle distribution. MTT assay was used to observe the lymphocyte transformation rate. Results ① Valdecoxib inhibited the growth of the tumor and increased the survival rate. ② 10~40 mg?kg -1?d -1 Valdecoxib increased the apoptosis rate from 19.1% in control group to 23.1%~29.1%, and did not affect the distribution of cell cycle. ③ The expression level of Bcl-2 was decreased and expression levels of Bax, COX-2, MMP-2, Caspase-3 and VEGF were not affected. ④ Valdecoxib did not affect the weight, the lymphocyte transformation rate, spleen index, and thyrus index of the mice. Conclusion The inhibitory effect of valdecoxib on Lewis tumor is associated with apoptosis.
