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 investigate the relationship between brachial ankle pulse wave velocity and the incidence of cardio-cerebral events in people aged over 40. Methods Cluster sampling method was used to prospectively study 4 380 residents aged over 40 in Guiyang City District from May to August in 2011. Data of ba-PWV were collected. The follow-up examination was conducted from July to November of 2014. According to ba-PWV values, participants were divided into three groups:<14 m/s (control, n=1 039) group, 14-17.9 m/s group (n=1 393) and≥18 m/s group (n=809). Multi-factor Logistic regression model was used to analyze the relationship between ba-PWV values and risk factors of cardio-cerebral events. Results After three-year follow-up, a total of 3 241 participants were included in the final analysis. The cardio-cerebral events were identified in 63 (2.0%) cases, which were 0.6%, 2.2%and 3.2%in control group, 14-17.9 m/s group and≥18 m/s group. The value of ba-PWV increased significantly in those two groups compared with that of normal group. Logistic regression analysis showed that the incidence rates of cardiovascular and cerebralvascular events in 14-17.9 m/s group and≥18 m/s group were 2.777 (1.123-6.864) and 2.786 (1.032-7.526) times of control group after adjusting age, gender, systolic blood pressure, risk factors of diabetes, hypertension and blood lipids. Conclusion There is higher incidence rate of cardio-cerebral events in people aged over 40 in higher ba-PWV group. The value of Ba-PWV can be used to predict the occurrence of cardio-cerebral events.
