Objective To observe the vascular collagen remodeling, apoptosis and Bcl-2/Bax of vascular smooth muscle cells in carotid artery on SHR . Methods 12 SHR treated with Irbesartan ,12 SHR without treated Irbesartan ,12 wistar rats were normotensive control group. The vascular volume fraction of Collagen were determined by picrosirius red staining .The expression of the proteins Bcl-2 and Bax were determined by Immunhistochemia,VSMC apoptosis was identified by in situ TDT-mediated dUTP nick end labeling(TUNEL). Results Significant Fibrosis exists in carotid artery of SHR. After 20 week's treating, the vascular volume fraction of Collagen and the ratio of wall/cavity were descended, but weren't parallel. The expression of the protein Bcl-2 and APOI were higher than the subjects of normotensive control, its reduced after treating; The expression of the proteins Bax was similar with control, it increased after treating. Conclusions The results suggest that vascular collagen remodeling exist, its maybe related with apoptosis , the proteins Bcl-2 and Bax of VSMC. The Irbesartan can treat it.

Cytosine deaminase (CD) gene is a kind of suicide gene, cytosine deaminase can catalyze the conversion from 5 - fluorocytosine (5 - FC) into 5 - fluorouracil (5 - FU), this combination therapy (CDgene/5 - FC) were widely used in cancer therapy. The results of many researches in different cancer cells have demonstrated that it can inhibit tumor growth significantly. The mechanism includes 5 - FU's direct killing tumor cells and its bystander effect. It can also be used as a potential purging method for autologous hematopoietic cells transplantion after chemotherapy in breast cancer patients. CD/5 - FC combined with other therapies would be an important future research approach.
