摘要： The present invention disclosed a kind of gutless adenovirus vector and the construction method thereof. Two structural independent but functional related cassettes, the trans-activator (TA) and anti-tumor cassette, are both carried by the gutless vector. hTERT promoter restricts the expression of TA only in tumor cells, and RU486, associated with TA, regulates the expression of interesting gene: when needed, add the RU486 and the gene expression is on, and when not needed, remove the RU486 and the gene expression is off. Tumor-specificity and small molecule regulation of the vector spare the toxicity to the normal tissue caused by the foreign gene product and endow the gene's long lifetime expression in vivo. The vector of the present invention shows many advantages over traditional adenovirus vectors in targeting, gene regulation and expression lifetime.

摘要： Disclosed is a catalyst for the polymerization of olefins comprising thienyl-substituted silanes, which comprises a solid titanium catalyst component containing titanium, magnesium and a halogen as the main components, an alkylaluminum compound, and a component of organosiloxane compound comprising two thienyl as substituents represented by general formula (I). The molar ratio of each catalyst component is 1:50-150:5-50 based on titanium:aluminum:silicon. When the catalyst is used in the polymerization of propylene, the polymerisate obtained has very high degree of isotacticity, and the yield is high.
