Objective To study the pollution levels,characteristics,causes and related adverse effects of indoor volatile organic compounds(VOCs) on human health after decoration. Methods The concentration of indoor air formaldehyde and TVOC were detected,meanwhile the adverse health effects were investigated by questionnaires. Result The results showed that the houses in which formaldehyde concentration exceeded the national indoor air quality standard occupied 47.1%, and three months later, the rate still was 40%,the highest level was 6.56 times of the standard. While the rate of exceed the national standard of TVOC was 76% within one month and 0% three months later respectively. As far as the concerned subjective syndromes, only the complaint of disgusted smell was significantly different between those who lived in newly decorated rooms and those who lived in the houses which taken as the control. Conclusion Now the pollution level of VOCs caused by decoration is some lower than before,but the pollution of formaldehyde was still pervasive and serious. The causes of pollution lay in artificial board materials used for furniture and decoration. Moreover, the complaints of the discomfort of eyes and upper respiratory tract will increase as people moved in the newly decorated rooms.

This study was designed to determine the effects of the recombinant adeno-associated virus vector containing sense CD151 gene (rAAV-CD151) and antisense CD151 gene (rAAV-antiCD151) on the migration of Tca8113 cell. Functional fragment of CD151 gene was amplified by RT-PCR, and inserted into the vector pAAV in the sense direction and antisense direction, respectively. The rAAV-CD151 and rAAV-antiCD151 were produced and the titers were determined by dot blot. The CD151, at protein level, was detected by Western blot. The Transwell chamber was used to detect the effects of the rAAV-CD151 and rAAV-antiCD151 on the tumor cell migration. The titers of the rAAV-CD151 and rAAV-antiCD151 were 2 x 10(11) pfu/ml and 1.0 x 10(11) pfu/ml, respectively. The expression of CD151 was increased by 108% in the cells transfected with rAAV-CD151 and decreased by 79% in the cells transfected with rAAV-antiCD151, as compared with non-transfected cells, respectively. The number of the migrating cells was significantly increased in the cells transfected with rAAV-CD151 (93.56 +/- 11.59) and decreased in the cells transfected with rAAV-antiCD151 (24.00 +/- 4.36) as compared with non-transfected and rAAV-GFP transfected cells (53.00 +/- 6.56 and 46.00 +/- 7.00, P<0.05). It is an important molecular mechanism of the tumor metastasis that the overexpression of CD151 promotes the migration of the tumor cells. The rAAV-antiCD151 is a novel tool, which can reduce the expression of CD151 and inhibit the migration of the tumor cells, and brings us a new approach of anti-sene gene therapy targeted at CD151 in human carcinoma.

BACKGROUND: A new method, i.e., heparin slow-release stent implantation combined with myocardium drilling, is discovered for myocardial revasculadzation, which remarkably improves myocardial perfusion. OBJECTIVE: To investigate the effect of heparin slow-release stent implantation combined with myocardium drilling on myocardial regeneration of pigs with acute myocardial infarction.METHODS: Anterior descending coronary of pig was ligated to induce myocardial infarction model, which was randomly divided into control and implantation groups, with 6 pigs for each group. Self-made borer was used in the implantation group to drill two transmural channels (3.5 mm diameter) on epicardium. A heparin slow-release stent was fixed in the transmural channel. Following intravenous injection, BrdU was used to label DNA duplication so as to observe stromal cell-derived factor-1 (SDF-1) mRNA expression, myocardial perfusion, newborn yocardium, and heart function prior to and following implantation. RESULTS AND CONCLUSION: As compared with control group, SDF-1 expression was enhanced in the implantation group at 6 weeks after stent implantation (P < 0.001), perfusion mass defect percentage was significantly decreased (P < 0.001), ejection fraction of left ventricle was increased (P < 0.05), newborn myocardium was increased (P< 0.001), and survival myocardium in the ischemic region was increased (P < 0.001). The results demonstrated that heparin slow-release stent implantation combined with myocardium drilling could repair damaged myocardial cells and improve heart function through increasing SDF-1 expression and myocardial perfusion.
