Objective: To exploration the self-efficacy, self-esteem, and positive/negative affect and the re-lationships among them in Chinese adolescents. Methods: The Rosenberg's Self-Esteem Scale, Generalized Self-Ef-ficacy Scale, and Adolescents Positive/Negative Affect Scale were administrated to 2247 middle school students sampled from 16 schools from 6 districts. Results: Self-esteem tended to increase as grade [(2.91±0.38), (2.93±0.41), (3.01±0.41), (2.98±0.44), (3.04±0.41), (3.17±0.42)]. Boys had higher self-efficacy [(2.74±0.39)vs.(2.68±0.40), P <0.001]. Two senior grades had higher self-efficacy than other 4 grades (P<0.05). Girls had higher positive and negative affect [(2.77±0.67)vs.(2.68±0.67), (2.22±0.70) vs.(2.13±0.68), Ps <0.05]. Junior grade one had the highest positive effect (2.85±0.62), grade one and two in high school had more negative effect than other 4 grades (2.26±0.71, 2.25±0.73).Self-efficacy and self-esteem were positively correlated with positive affect (r=0.24, 0.36), negatively correlated with negative af-fect (r=-0.17, -0.32) ; self-esteem significantly mediated the relationship between self-efficacy and positive/negative affect (Z=13.00, -13.07) . Conclusion: Self-esteem tends to increase as grade, boys have higher self-efficacy than girls, and girls have higher positive and negative affect than boys. Self-esteem mediates the rela-tionship between generalized self-efficacy and positive/negative affect in Chinese adolescents after controlling the effects of gender and grade.

Pediatric blood purification requires reliable access to the circulation.Central venous catheters play an important role in the delivery of pediatric blood purification.A central venous noncuffed,nontunneled catheter is the best choice for short-term(less than 3 weeks) blood purification.A cuffed,tunneled catheter is preferable to long term(more than 3 weeks) blood purification.However,there are many complications associated with central venous catheters,such as catheter-induced thrombosis,catheter-related infection,and central vein stenosis.This article reviews the prevention and treatment of complications most frequently occurring with central venous catheters.

Using calmodulin dependent cyclic neucleotide phosphodiesterase and dansyl-labeled calmodulin,honokiol's action on calmodulin is studied. It is found that honokiol inhibits the activity of cyclic neucleotide phosphodiesterase induced by stimulus of calmodulin. With the increasing of calmodulin concentration, the IC50 value was increased. In the presence of Ca2+, honokiol reduces the fluorescence intensity of dansyl-calmodulin, and makes the spectrumpeaked red. The results indicate that honokiol can combine with calmodulin in the presence of Ca2+ and antagonise the effect caused by calmodulin's stimulation upon the phosphodiesterase. In addition , honokiol may exert its effect on the basal activity of calmodulin dependent cyclic neucleotide phosphodiesterase.

Certain measures for their integration were proposed, such as strengthening network construction, perfecting literacy education systems, and carrying out systemic training.Integration of MOOC and information literacy education in academic libraries can improve information service, promote wide application of MOOC and information literacy ed-ucation in academic libraries.

Objective:To establish an HPLC method for the determination of two components and the preservative in compound dextromethorphan hydrobromide syrups. Methods:An Agilent Zobax SB-C18 column(250 mm × 4. 6 mm,5 μm) was used with meth-anesulfonic acid solution (adding 4. 8g methanesulfonic acid and 10ml triethylamine into 750ml water,and adjusting the pH value to 3. 5 by phosphoric acid)-acetonitrile (75∶25) as the mobile phase at the flow rate of 1. 0 ml·min-1 and 280nm as the detection wave-length. Results:The calibration curve was linear within the range of 102-1 025μg·ml-1 for guaifenesin,15-619μg ·ml-1 for dextro-methorphan hydrobromide and 10-407μg·ml-1 for benzoic acid. The average recovery of guaifenesin, dextromethorphan hydrobromide and benzoic acid was 100. 0% (RSD=0. 35%), 100. 1%(RSD=0. 77%)and 100. 8%(RSD=0. 49%), respectively. Conclusion:The method is simple,rapid and accurate,and suitable for the quality assessment of compound dextromethorphan hydrobromide syrups.
