Objective To explore the relationship between the critical thinking disposition and the innovation behavior in nurses. Methods A total of 360 clinical nurses were questionnaired by the critical thinking disposition inventory and innovation behavior scale. Pearson correlation analysis and hierarchical regression analysis were used to explore the effect of critical thinking disposition on the innovation behavior in nurses. Results The total scores of critical thinking disposition and innovation behavior in nurses were respectively 290.68±33.46 and 4.12±0.96. There was significant difference of the score of innovation behavior in nurses with different professional titles and working years(F=6.257, 4.802, P<0.05). The score of innovation behavior was positively correlated with the scores of seek truth, open mind, analysis ability, systematic ability, self-confidence, learning desire and cognitive maturity(r=0.367-0.514, P<0.05). Hierarchical regression analysis showed that the seek truth, open mind, analysis ability, systematic ability, self-confidence, learning desire and cognitive maturity were the influencing factors of innovative behavior in nurses. Conclusions The critical thinking disposition and innovation behavior were in medium level in nurses, and the critical thinking disposition was the influencing factors of innovative behavior in nurses.

Objective To discuss the feasibility,safety and validity of ViabahnTM self-expanding covered stent in endovascular repair of femoral pseudoaneurysm caused by intravenous drug injection.Methods The clinical data of 9 patients with femoral pseudoaneurysm caused by intravenous drug injection,who were admitted to authors' hospital during the period from April 2014 to April 2015,were retrospectively analyzed.The pseudoaneurysms were located at the common femoral artery in 6 patients and at the superficial femoral artery in 3 patients.Endovascular repair with ViabahnTM self-expanding covered stent was performed in all the 9 patients.The intraoperative angiographic findings,the sizes of the implanted stents,and the manifestations of the angiography performed immediately after stent implantation were recorded,after operation,the patients were kept under close observation to evaluate the improvement of clinical symptoms,the effect of pseudoaneurysm repair,and the occurrence of endoleak,stent infection,in-stent stenosisand fracture of stent.Anti-infection treatment was employed both before and after the stent implantation;after the stent implantation debridement and/or drainage for soft tissue infection area of inguinal region was adopted.Results Successful implantation of ViabahnTM self-expanding covered stent was accomplished in all 9 patients,with a technical success rate of 100％.Angiography performed immediately after stent implantation showed that complete repair of pseudoaneurysm cavity was obtained in all 9 patients,the distal segment of the parent artery was patent,and no endoleak occurred.The patients were followed up for 6-12 months,and limb salvage was successful in all patients,no intermittent claudication or muscular atrophy occurred.CT angiographyreexamination showed that no endoleak,stent infection,stent fracture or in-stent stenosis occurred.Conclusion Under the conditions of adequate anti-infection,local debridement and drainage,the use of ViabahnTM self-expanding covered stent can promptly close the break of femoral pseudoaneurysm to save the patient's life.Because of the excellent qualities,such as flexibility,adhesion and patency,of ViabahnTM self-expanding covered stent,the postoperative occurrence of intermittent claudication,stent fracture and in-stent stenosis can be effectively reduced.It is expected that ViabahnTM self-expanding covered stent may become one of the vascular reconstruction methods for femoral pseudoaneurysm caused by intravenous drug injection,although its long-term curative effect needs to be further observed and verified.

OBJECTIVE:To study the HPLC fingerprint profiles of crude and processed Semen Cassiae so as to provide basis for the establishment of chromatographic fingerprint of Semen Cassiae.METHODS: The samples of Semen Cassiae were hydrolyzed in the 1.5 mol?L-1 hydrochloride acid and then reflux extracted with chloroform.The HPLC analysis was run in gradient elution.The whole information of single-wavelength chromatographic fingerprint,two-dimension information data at full wavelength 220 nm～550 nm and the data of 18 fingerprint peaks compared with chrysophanol were treated by cluster analysis.RESULTS:It was observed that the contents of several chemical components were higher in the crude or processed Semen Cassiae than in chrysophanol.There were differences between the crude and the processed Semen Cassiae in HPLC fingerprint profiles though they were of good similarity.CONCLUSION: The HPLC fingerprints of liposoluble constituents were obtained with good resolution under the experimental chromatographic system.Three pure chromatographic peaks of chrysophanol,emodin and physcion have been identified.More reliable cluster result can be obtained from two-dimension information data at full wavelength 220 nm～550 nm than from the whole information of single-wavelength chromatographic fingerprint or from the information of chromatographic fingerprint of characteristic peaks.

OBJECTIVE:To explore the effects of enteral nutrition powder in children with phenylketonuria(PKU)under one year. METHODS:120 PKU children under one year were selected and given enteral nutrition powder(20 g/kg,qd)for consecutive 32 weeks. The level of benzene,height,weight,head circumference,IQ level,nutrition indicators and ADR were compared be-fore treatment,8 weeks after treatment,32 weeks after treatment. RESULTS:8 and 32 weeks after treatment,the level of benzene decreased gradually,and height,weight and head circumference increased gradually,with statistical significance(P<0.05). IQ lev-el of children after 8 weeks treatment were better than before,and those of children after 32 weeks treatment were better than after 8 weeks treatment,with statistical significance(P<0.05). 8 and 32 weeks after treatment,nutrition indicators were improved sig-nificantly,compared with before treatment;ALT,Alb and TP levels 32 weeks after treatment were significantly better than 8 weeks after treatment,with statistical significance(P<0.05).There was no statistically significant difference in BUN,TBil and Pa levels between 32 weeks after treatment and 8 weeks after treatment(P>0.05). 66 cases suffered from 181 times of ADR,mainly including 10 times diarrhea and 126 times upper respiratory tract infection,among which one children developed moderate gastroen-teritis. They were all recovered after symptomatic treatment. CONCLUSIONS:For PKU children under one year,enteral nutrition powder can effectively control the phenylalanine levels,prevent the decrease of IQ and improve the nutritional status so as to meet the normal growth and development of children nutritional requirements,with better safety and tolerance.

Objective To determine mitochondria-associated signaling pathway on cell apoptosis in Leptospira interrogans infected murine mononuclear-macrophages. Methods A cell apoptotic model of L. interrogan serogroup Icterohaemorrhagiae strain Lai inducing apoptosis of murine mononuclear-macrophage line (J774A. 1) was established. Pathological changes of mitochondria in the infected cells were observed under transmission electron microscope. Mitochondrial potential and reactive oxygen species(ROS) levels in the infected cells were detected using JC-1 staining method and DCFH-DA fluorescent probe, respectively,and caspase-8/-9 activities in the infected cells were measured using commercial kits. and the apoptosis block effects of caspase inhibitors were determined by flow cytometry. Apoptosis in the infected cells and ap-optosis-blocking effect by caspase inhibitors were detected by flow cytometry. Western blot assay was adopted to examine the levels of cytochrome C (CytC) , AIF, EndoG and Smae in the mitochondria and cytoplasm.The transposition of either AIF or EndoG from the cytoplasm into cell nucleus was determined by immunoflu-orescence staining test. Results L. interrogans strain Lai could induce J774A. 1 cell apoptoais. In the in-fected cells, visible mitochondrial injury, declined mitochondrial membrane potential and elevated ROS level were presented. The activity of caspase-8 but not of caspase-9 was significantly increased. The caspase in-hihitors could not completely block the cell apoptosis. Both the AIF and EndoG was released from the mito-chondria and subsequently transferred from the cytoplasm into the nucleus in the infected cells. However,elevation of CytC level and Smac release in cytoplasm of the infected cells could not be found. Conclusion L.interrogans can induce apoptosis in the infected mononuclear-macrophage via AIF and EndoG belonging to caspase-independent pathway.
