Objective:To translate the best evidence of cerebrospinal fluid external drainage management into clinical practice, so as to standardize the behavior of nurses, improve the qualified rate of cerebrospinal fluid external drainage management, and improve the quality of nursing.Methods:Follow the JBI′s Practical Application of Clinical Evidence System and Getting Research into Practice audit, the research team selected the best evidences about five dimensions, and formulated 13 evaluation criteria. A 40-case baseline audit in a Neurosurgical ward to identify problems in implementation of this evidences were performed. After that they provided training courses and strategies to get these evidences into practice, and conducted a 40-case post-implementation audit in the same ward.Results:The compliance rates of all the 13 criteria were increased except No.11 ( χ2 values were 8.889-34.290, P<0.01). The qualified rate of total amount control of cerebrospinal fluid drainage increased from 57.5% (23/40) to 100.0% (40/40), the qualified rate of drainage speed control increased from 40.0% (16/40) to 100.0% (40/40), and the qualified rate of health education increased from 42.5% (17/40) to 90.0% (36/40), with statistical significance ( χ2 values were 21.590, 34.290, 20.180, P < 0.01). Conclusions:Put the best available evidence regarding cerebrospinal fluid external drainage into practice canpromotes evidence-based nursing practice, standardized nurses′ behaviors, realized continuous improvement of nursing quality, and can reduce the risk of complications and ensure patient′s safety.

Objective:Chemical constituents of Sophora flavescems Ait. were studied by different extraction. Methods: Online HPLC/ESI/MS was used to study the different extraction. Results: numbers of alkaloids and flavone from Sophora flavescens Ait. were 9,8 and 12, respectively by means of chloroform strong aqua , water , and water methanol extraction. Conclusions: For the first time, we studied extraction of Sophora flavescems Ait by HPLC MS. This provided basic for study on fingerprints of Sophora flavescems Ait..
