The tryptophan residues play important roles in DNA photoreactivation catalyzed by CPD photolyases. We have investigated the action mechanism concerning Trp in DNA photoreactivation, and obtained the results as follows: 1 We proposed a mechanism of photosensitized splitting of CPDs by Trp and Trp-containing peptides. 2 Quantum yields of splitting of the model compounds that a Trp linked covalently a CPD were obtained under 290 nm light in various solvents, these values changing with solvent, range from 0.01 to 0.5. 3 Utilizing pulse radiolysis technique, splitting processes were observed in aqueous solution of the CPDs with hydrated electron and some oxidative species (such as hydroxyl radical, bromic radical and azide radical), and obtained their rate constants. In the case of interaction between CPD and hydrated electron, splitting of the CPD anion, and pyrimidine anion transfer an electron to FAD or Rf, were observed. The process rate was slower one order more than that in photolyase. Minor, but highly mutagenic UV-light-induced lesions are (6-4) photoproducts, which are repaired by (6-4) photolyases. These enzymes, discovered in 1993, are not well characterized and their mechanism is still under investigation.

The swift and violent development of the modern science and technology makes western societies generally enter consumption society, The consumption society supports the goods going to aesthetic and aesthetic going to goods at the same time,all of this has created unprecedented democratic era of arts and aesthetics, on the other hand even enable the most important aesthetic target --Art ,suffering all kinds of economical bulling and losing elite characters and self-disciplining,especially because consumerism stresses the artistic works whether having symbol value ,whether using marketing technology,and whether concerning to economy reciprocate.The pop art have became the mainstream of the art form of our time.

现代科学技术的迅猛发展使西方社会普遍进入消费社会，消费社会同时支持商品的审美化与审美的商品化，这一方面创造了前所未有的艺术、审美之民主时代，另一方面也使最重要的审美对象——艺术，受尽经济霸权主义的欺凌而丧失了精英性与自律性，特别是消费主义讲究艺术商品对符号价值的追求、对营销技术的使用、对经济回报的关注，使得流行艺术成为时代艺术形式之主流，从前那个只关心艺术作品之艺术性的美学传统已经被既关注艺术性又关注消费性的&新美学原则&代替。
