BACKGROUND:Great saphenous vein is the most common vascular material in coronary artery bypass grafting, however, the graft neointimal hyperplasia and subsequent atherosclerosis result in angiostegnosis, which affect the long-term efficacy. OBJECTIVE: To analyze the pathophysiology and mechanism of the angiostenosis, additionally, to construct smooth muscle cell specific SM22a promoter and SMHC enhancer. METHODS: The database of PubMed, HighWire and CNKI were retrieved with key words of "SM22α promoter, SMHC enhancer, stenosis, Pi3k and RNAi/RNA interference". The language was confined to English and Chinese. The literatures correlated with angiostenosis, VSMC-specific SM22α promoter and enhancer were selected. The reviews and overlapped researches were excluded. In vascular smooth muscle cell proliferation and apoptosis of graft neointimal hyperplasia, as well as the extent of graft thrombosis were considered as evaluation index. RESULTS AND CONCLUSION: More than 8 730 literatures were searched by the computer. According to inclusion and exclusion criteria, the SM22α promoter and angiostenosis were analyzed. The neointimal hyperplasia and thrombosis had a strong impact on prospective efficacy after coronary artery bypass grafting. The PI3K-Akt-mTOR pathway was a crucial signal passage which regulated cell proliferation and migration. RNA interference targeting Pik3cb can efficiently suppress the neointimal hyperplasia through down regulating the PI3K-Akt-mTOR pathway. The shRNA eukaryon expression plasmid vectors targeting rat Pik3cb were constructed using VSMC-specific SM22α promoter. On the one hand, it can suppress the neointimal hyperplasia, and on the other, it can prevent the occurrence of thrombosis.SM22a is a specific gene in vascular smooth muscle cell. The studies that applied VSMC-specific SM22α promoter/enhancer to vascular grafting provide a new strategy to prevent angiostenosis and thrombosis.

AIM: To investigate whether a pathological micro-environmental culture system consisting of cholestatic sera induces embryonic stem cells (ESC) to differentiate into hepatocyte-like cells in vitro, and select hepatic stem cells from differentiating embryonic stem cells. METHODS: Mouse ESC, E14 cell line, were cultured in Dulbecco's modified Eagle's medium containing 106 U/L recombinant mouse leukemia inhibitory factor (rmLIF) and 10% FCS. After embryonic bodies formed by the hanging drop culture method, they were exposed to fibroblast growth factor-4 (FGF-4) and hepatocyte growth factor (HGF) for one week, and then placed to a pathological micro-environmental culture system consisting of 5% cholestatic sera and cultured for 2 weeks. Morphological examination, immunocytochemical staining of albumin and CK8/18 were carried out, and mRNA level of albumin and transthyretin were detected by RT-PCR. Glycogen storage and urea synthesis of the cells were tested with PAS staining and colorimetric assay, respectively. RESULTS: The proliferation of cells was inhibited at the early stage when cultured in a pathological micro-environmental culture system consisting of 5% cholestatic sera, but 2 weeks later, a large number of epithelial-like cell colonies were observed, which exhibited hepatocellular phenotype, expressing albumin and CK8/18, transcribing mRNA of albumin and transthyretin and synthesizing glycogen and urea. CONCLUSION: A pathological micro- environmental culture system consisting of 5% cholestatic sera could not only induce embryonic stem cells to differentiate into hepatocyte-like cells, but select hepatic stem cells from differentiating embryonic stem cells initially induced by FGF-4 and HGF in vitro as well.
