RESUMEN

Objective To investigate the current status of moral distress in clinical nurses,and analyze its influential factors.Methods A total of 240 clinical nurses were recruited by stratified sampling method.They were investigated with general situation questionnaire and moral distress scale.Results The average score of moral distress was (2.66±0.41).Multiple linear regression analysis showed that department of work and qualification were influencing factors on moral distress of clinical nurses.Conclusions This study found that nurses' moral distress was above the middle level.Some targeted measures should be taken by nursing managers,in order to help decrease nurses' moral distress.

RESUMEN

<p><b>OBJECTIVE</b>To establish a SPE-HPLC method for the determination and pharmacokinetic study of evodiamine and rutacarpine in rat plasma.</p><p><b>METHOD</b>A Kromasil C18 column (4.6 mm x 250 mm, 5 microm) was used with acetonitrile-water-tetrahydrofuran-acetic acid (51:48:1:0.1) as a mobile phase and at a flow rate of 1 mL x min(-1), and the UV detection was at 225 nm. The column temperature was 35 degrees C. After the analytes were extracted from the plasma of rats by solid phase extraction (SPE), the content of evodiamine and rutaecarpine was measuared by HPLC method using halcinonide as an internal standard solution.</p><p><b>RESULT</b>After transdermal administration to rats, the pharmacokinetic behavior of evodiamine and rutaecarpine belongs to the one-compartment model. The main pharmacokinetic parameters was as follows: K(a) 0.224 h(-1) and 0.220 h(-1), K(e) 0.114 h(-1) and 0.118 h(-1), C(max) 0.211 mg x L(-1) and 0.272 mg x L(-1), T(peak) 6.132 h and 6.102 h, respectively.</p><p><b>CONCLUSION</b>The method in this study is simple, rapid and sensitive. It is proved to be suitable for pharmacokinetic study of evodiamine and rutaecarpine.</p>

RESUMEN

Objective To establish a HPLC method of determining chrysin and baicalein in Senmen Oroxyli. Method The contents of chrysin and baicalein were determined by HPLC. The chromatographic conditions were: Kromasi1-C_(18) column (5 ?m, 250 mm?4.6 mm), with methanol-acetonitrile-water-glacial acetic acid (25 : 25 : 50 : 0.2) as the mobile phase, at the flow rate of 1 mL/min, the detecting wavelength at 275 nm and at the room temperature. Results The contents of baicalein and chrysin could be detected by this HPLC method, and got good separation and good linear relationship. RSD were 1.53% and 1.35%, indicating good repeatability, recovery RSD were 1.85% and 1.59%, indicating a good recovery. Conclusion The method is simple, feasible and repeatable, and can be provide reference for quality control of Senmen Oroxyli.
