It was found that Ag nanoparticles (NPs) could enhance the chemiluminescence (CL) intensity of luminol- potassium ferricyanide system. On the basis of enhancement effect,a flow injection method was developed for the determination of terbutaline sulfate. The structure and shape of Ag NPs were characterized by transmission electron microscopy. The UV-Vis absorption spectra and chemiluminescence spectra suggested that new luminophor was not formed after Ag NPs introducing in luminol-potassium ferricyanide chemiluminescence system. A possible mechanism of Ag NPs strengthening on luminol-potassium ferricyanide CL reaction was also discussed. The effect of concentration of luminol,potassium ferricyanide,sodium hydroxide and Ag NPs on CL reaction was investigated respectively. In the optimum conditions,the linear range was 1.0×10~(-9) -2.0 ×10~(-5) g/L(r =0.9935) and the detection limit was 1×10~(-10) g/L. The relative standard deviation (RSD) was 3.6% for 1. 0 ×10~(-6) g/L terbutaline sulfate (n = 11 ). The recommended method has been successfully applied to the determination of terbutaline sulfate tablets and the recovery was between 98. 5% - 102. 5% ,moreover the results were almost identical with the same results of Pharmacopoeia method.

Objective:To analyze the distribution of UGT1A1 gene polymorphisms in Chinese Han patients with extensive-disease small cell lung cancer(ED-SCLC),and evaluate the correlation between UGT1A1 gene polymorphisms and toxicity and efficacy of irino-tecan(CPT-11) based regimen in the patients with ED-SCLC. Methods: The analysis of UGT1A1?28 and UGT1A1?6 gene poly-morphisms was performed in 67 patients with ED-SCLC admitted in our hospital from June 2011 to January 2013. The 67 cases with ED-SCLC treated with irinotecan(CPT-11) based regimen were enrolled to observe the adverse events and efficacy during the chemo-therapy, including objective responserate rate ( ORR) , progression free survival ( PFS) and overall survival ( OS) . The incidence of different genotypes was compared. Results:The distribution of UGT1A1 genotypes in the 67 patients was follows:UGT1A1?28 wild-type (WT) genotype TA6/6 (56, 83. 6%), heterozygous genotype TA6/7 (11, 16. 4%);UGT1A1?6 wild-type (WT) genotype G/G (45,67. 2%), heterozygous genotype G/A (22,32. 8%). No significant difference of PFS and OS was observed between the differ-ent genotypes. The incidence of grade 3 and 4 delayed diarrhea and neutropenia in the patients carrying UGT1A1?6 G/A was higher than that in those with WT genotype (36. 4% vs. 6. 6%, P<0. 05;27. 2% vs. 4. 4%, P<0. 05, respectively). The incidence of grade 3 and 4 thrombocytopenia in the patients carrying UGT1A1?28 TA6/7 was higher than that in those with WT genotype (27. 2%vs. 1. 8%, P<0. 05). The patients simultaneously carrying UGT1A1?28 TA6/7 and UGT1A1?6 G/A were prone to suffering 3 and 4 delayed diarrhea and neutropenia. Conclusion: UGT1A1 polymorphisms may predict the adverse events of CPT-11 in ED-SCLC, while can not predict the efficacy of CPT-11.
