The hTERT gene promoter is a tumor-specific promoter, regulated by a number of factors.Modulation of the chromatin structure via DNA methylation or histone acetylation plays an important role in regulating the hTERT promoter. Recent study also found that glycogen synthase kinase -3 cytokines, macrophage colony-stimulating factor receptor 1, bone inducing factor -7, transcription factors c-myc inhibitor, transforming growth factor β, cyclopentenone prostaglandin regulate the activity of hTERT through various pathways. Telomelysin, the telomerase-specific replication competent oncolytic adenovirus, has been used in clinical settings.Various gene therapies based on hTERT are current under-way.

Objective To explore the effect of three shifts on sleep status of nurses in order to supply evidence for improving the nurses' sleeping quality. Methods 111 three shifts nurses and 117 traditional shifts nurses of 3 grade three A hospitals in Guangzhou were investigated for their sleep condition with self-rating scale of sleep (SRSS), and later the results underwentχ2 test and t test. Results There were 55 three shifts nurses with sleeping factor scores of SRSS≥23 (49.5 %), while there were 72 traditional shifts nurses with sleeping factor scores of SRSS≥23 (61.5 %). Compared with traditional shifts nurses, the total mean scores and factor score of three shifts nurses were better except sleeping time and lack of awakening. It is discovered that great sleeping status differences were found among three shifts nurses and traditional shifts nurses between the age of 20 to 30. Conclusions Three shifts can release the pressure of nurses and can improve the nurses' sleeping status to some degree, especially to the juniority nurses' sleeping status,then the nursing safety can be insured.

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.
