| 1 | The effects of CYP1A1 gene polymorphism and p16 gene methylation on the risk of lung cancer in a Chinese population显示文摘Objective:To investigate the relationship between the genetic polymorphism of CYP1A1 and the genetic susceptibility to lung cancer as well as to study the effects of the methylation in p16 gene on the risk of lung cancer in a Chinese population.Methods:A case control study was conducted among 47 cases of lung cancer and 94 controls.The genetic polymorphism of CYP1A1 was tested with method of PCR-RFLP,and a methylation-specific PCR(MSP)was performed to detect p16 methylation.Results:It showed that there was no significant difference in frequencies of the genotypes of CYP1A1 between the two groups(P>0.05).Synergistic effects were not found between smoking and CYP1A1.Methylated p16 gene was found in 44.7%(21/47)of lung cancer tissues and in 17.0%(8/47)of normal lung tissues with significant difference(P< 0.05).Conclusion:The genetic polymorphism of CYP1A1 does not increase the risk of lung cancer in a Chinese population. The methylation in p16 gene may be the most common mechanism to inactivate p16 gene in lung cancer,and is not significantly associated with genotype of CYP1A1. | Wenhu Tao Yongtang Jin Zaicheng Yu Xiao Liu | 2007 | The Chinese-German Journal of Clinical Oncology2007，6，4： | 2 |
| 2 | Synergistic CO_(2)reduction and tetracycline degradation by CuInZnS-Ti_(3)C_(2)T_(x)in one photoredox cycle显示文摘Optimizing photocatalytic CO_(2)reduction with simultaneous pollutant degradation is highly desired.However,the photocatalytic efficiency is restricted by the unmatched redox ability,high carriers’recombination rate,and lack of reactive sites of the present photocatalysts.Herein,the CuInZnS-Ti_(3)C_(2)T_(x)hybrid with matched redox ability and suitable CO_(2)adsorption property was rationally synthesized.The nucleation and growth process of CuInZnS was interfered by the addition of Ti_(3)C_(2)T_(x)with a negative charge,resulting in thinner nanosheets and richer reactive sites.Besides,the Schottky heterojunction built in the hybrid simultaneously improved the photoexcited charge transfer property,sunlight absorption range,and CO_(2)adsorption ability.Consequently,upon exposure to sunlight,CuInZnS-Ti_(3)C_(2)T_(x)exhibited an efficient photocatalytic CO_(2)reduction performance(10.2μmol·h^(−1)·g^(−1))with synergetic tetracycline degradation,obviously higher than that of pure CuInZnS.Based on the combination of theoretical calculation and experimental characterization,the photocatalytic mechanism was investigated comprehensively.This work offers a reference for the remission of worldwide energy shortage and environmental pollution problems. | Lijing Wang Zhan Zhang Renquan Guan Dandan Wu Weilong Shi Limin Yu Pan Li Wei Wei Zhao Zhao Zaicheng Sun | 2022 | Nano Research2022，15，9： | 0 |
