Objective To investigate current status of knowledge-attitude-behavior about unplanned extubation (UEX) of central venous catheter among infusion nurses in Guangdong Province.Methods The nurses who attended the 2015 intravenous therapy nursing training provided by Guangdong Nursing Association were selected as participants.A self-designed questionnaire about nurses' knowledge-attitude-behavior about UEX of central venous catheter was used to investigate 450 nurses.Results The proportion of nurses who reached good level in knowledge were 41.1%,nurses who had positive attitude were 71.0%,nurses who had positive behaviors were 30.0%.There were significant differences among nurses with different educational background,different titles and different hospital ranks(P<0.05).Conclusion The knowledge-attitude-behavior of nurses are not satisfactory,especially those who are junior or have lower education or work in non-tertiary hospital.

Objective To investigate the growth inhibition effect of evodiamine (Evo) on renal carcinoma 786-0 cells and to explore its molecular mechanism. Methods After treated with Evo, methyl thiazolyl tetrazolium ( MTT) assay was used to detect the vitality of 786-0 cells, flow cytometry was employed to examine the cell cycle distribution in 786-0 cells, and immunoblotting was utilized to determine the expression levels of target proteins related to cell cycle progression. Results Evo remarkably inhibited 786-0 cells vitality in dose-dependent manner. Cell cycle analysis indicated that 786-0 cells were arrested in G2/M phase followed by Evo treatment. Furthermore, the results of immunoblotting showed that Evo up-regulated the protein expression levels of P53, P21 and its downstream target gene CyclinB1 in 786-0 cells. Conclusion Evo treatment can induce 786-0 cell cycle G2/M arrest, and its underlying mechanism might be dependent on the P53/P21 signal pathway.

Objective To investigate the effect of ultrasound technology combined with Seldinger technique in the catheteration of peripherally inserted central catheter(PICC).Methods One thousand and eight malignant tumor patients undergoing PICC catheteration were divided into two groups:those with visible or palpable bouncy vein as the control group(n=540)and those with invisible or impalpable elbow vein as the experiment group(n=468).The control group were treated with PICC catheteration into the elbow vein as normal control group and in the experiment group the catheteration was done into the lower part of the upper arm of the basilic vein or brachial vein as the puncture point under the guidance of ultrasound with Seldinger technique.The two groups were compared in terms of success rate of one time puncturing, success rate of one time catheterization and postoperative phlebitis,venous thrombosis and catheter related infection rate.Result There were no significant difference in the success rate for one time puncturing,while the success rate of one time catheterization in the experiment group was significantly higher than that in the control group and the mechanical phlebitis,venous thrombosis,catheter related infection rate in the experiment group were significantly lower than those in the control group(P<0.001).Conclusion Ultrasound technology combined with Seldinger technique for PICC catheterization can obtain high success rate,lower postoperative complications and provide high security.
