Objective:To describe the status and influencing factors of emergency nurses′ high-alert drugs knowledge level in maternal and child hospital.Methods:Totally 171 nurses working in emergency department from 6 hospitals in Chengdu including West China Second University Hospital, Sichuan University, Sichuan Maternal and Child Health Hospital, Chengdu Women and Children Central Hospital, Chengdu Longquanyi Maternal and Child Health Hospital, Chengdu Chenghua Maternal and Child Health Hospital, Chengdu Pengzhou Maternal and Child Health Hospital were selected through convenient sampling to fill out the scale.Results:Nurses′ average score of high-alert drugs knowledge was 29.52±2.74. The accuracy of each item ranged from 22.2% to 100.0%. Multivariate linear regression analysis showed that major influencing factors for their knowledge level included monthly income, length of service in the emergency department, professional title, the model explained 12.7% amount of variance ( R2 value was 0.127, P<0.01). Conclusions:Emergency department nurses in maternal and child hospitals have insufficient awareness of intravenous infusion of high-alert drugs, and they have a high demand for knowledge. In order to ensure the safety of clinical drug use, it is urgent to formulate targeted training programs to improve nurses' knowledge level of high-alert drugs.

With the quick development and the requirements of internationalization of China's higher education,bilingual education has become a teaching task which is actively carried out in universities.Basic medical courses has strong professional and high abstractive characteristics.The bilingual education of basic medical courses have special requirements.Problems of bilingual education in basic medical courses teaching and possibly solutions were discussed to help better understanding of the bilingual teaching of basic medical courses and exert its advantages.

Objective:To investigate the cytokine profile expressed by CIK cells.Methods:CIK cells were induced from peripheral blood mononuclear cells in the presence of IFN-?,IL-1?,IL-2 and mAb against CD3. The phenotype and characterization of CIK cells were identified by flow cytometric analysis.Cytokine expression profiles were determined at mRNA level by semi-quantitative RT-PCR.Results:The percentage of CD3~+CD56~+ positive cells reached up to or higher than 50%.CIK cells couldn't express IFN-?、IFN-? and IFN-? under this kind of condition. But they could express IFNs principally on day 10 to 20. The level of ILs went down after steadily expressed on day 6 to 10(or 20).TNF-? and TRAIL constitutively expressed during the culture period in vitro. TNF-? maintained high expression on day 20.TGF-?_1 mainly expressed on day 30.Conclusion:CIK cells can widely express various kinds of cytokines in vitro.

Objective To study the expression of the fused proteasome activator REGγ(11S regulator complex gamma subunit) using gene recombination technology and to further study the interaction between REGγ and casein kinase-2 interacting protein-1(CKIP-1)in vitro.Methods Firstly, the full length cDNA fragment of REGγ was amplified through PCR using the plasmid pCMV-Myc-REGγ as template and subcloned into the prokaryotic expression vector pGEX-4T-2 before being transformed into E.coli BL21 cells. The protein expression was induced by isopropyl-β-D-thiogalactoside(IPTG) .Secondly, the protein expression was monitored by SDS-PAGE and Western blotting after ultrasonication. Finally, the GST Pull-down assay was performed to investigate the interaction between REGγ and CKIP-1 in vitro.Results The prokaryotic expression construct pGEX-4T-2-REGγ was generated successfully and confirmed by DNA sequencing. Expression analysis showed that the GST-REGγ protein was easily expressed and isolated mainly in the lysate supernatant after sonication and centrifugation. The GST Pull-down assay revealed the strong mutual interaction between REGγ and CKIP-1 in vitro.Conclusion The proteasome activator REGγ could interact with the negative regulator of osteoblastogenesis CKIP-1 in vitro and the current study has shed light on further investigations of their physiological relevance.

Objective To evaluate the value of echocardiography in the diagnosis of truncus arteriosus communis(TAC)and associated intracardiac malformations. Methods We retrospectively reviewed 30 patients with TAC, their datum of clinical and echocardiographic diagnosis were studied during the period of January 2006 to May 2014 in Shengjing Hospital Affiliated to China Medical University. Results Based on Collet Edwards method, these 30 TAC patients included 10 cases of typeⅠ, 7 cases of typeⅡ, 5 cases of typeⅢ, 8 cases of typeⅣ. The most common associated intracardiac malformation was ventricular septal defect in 24 cases, 16 cases had arterial septal defect, 7 cases had patent ductus arteriosus, 6 cases had single ventricle, 3 cases had right aortic arch, etc. Among them, 8 cases were confirmed by surgery, 5 cases of typeⅠ, 3 cases of typeⅡ, and 1 case of typeⅠdied after operation;16 cases were confirmed by CT angiography (CTA) examinations, all of them died without operation within 6 months. Conclusion Echocardiography is a preferred and non-invasive method for TAC and the intracardiac malformations.

Objective To improve the method to establish a rat model of vascular dementia and to better serve the experimental studies on vascular dementia.Methods We used the method of“repeatedly clipping the carotid artery com-bined with injection of sodium nitroprusside and with permanent unilateral carotid artery ligation” to prepare a rat model of vascular dementia.The drug piracetam was used to validate the established rat model in respect of the behavior and histopa-thology.Results Different from the reports of previous research, firstly, the results of this study suggested that injection dose of sodium nitroprusside should be 2.0 mg/kg, room temperature should be controlled at 28℃ during surgical opera-tion, and kept at 25℃postoperatively for 24 hours.Under these experimental conditions, the rats were stable and the death rate was reduced.Secondly,“repeatedly clipping carotid artery combined with permanent unilateral carotid artery ligation”could cut off about a third of cerebral blood supply, and causing chronic cerebral ischemia, which is seemingly more con-sistent with the pathogenesis of vascular dementia.Experimental results showed that compared with the control group, the navigation incubation period was extended and space search ability became worse in the model group, cell number was de-creased, with blurred cell contour and deeply stained cytoplasm, and cell nuclei were not clear in the hippocampal tissue. Conclusions Our findings indicate that the improved methodrepeatedly clipping the carotid artery combined with injec-tion of sodium nitroprusside and with permanent unilateral carotid artery ligationcan be used to efficiently establish a rat model of vascular dementia.The similar results of experiment using piracetam validate that this rat model can be used in vascular dementia-related experimental studies.

Objective To identify the glycometabolism features ofC57BL/Ksj db/+ mice at gestational period and provide the evidence for the mice used as the animal model of gestational diabetes mellitus (GDM).Methods Ten C57BL/Ksj db/+ female mice and ten wild female mice were randomly selected and mated with wild male mice respectively.Day 3 before mating,days 6,11 and 17 of pregnancy,and day 6 after delivery represented pre pregnancy,early-pregnancy,mid-pregnancy,late-pregnancy and post-pregnancy periods,respectively.The levels of glucose tolerance and fasting insulin of female mice were compared at progestation,different gestational periods and puerperium between the two groups.Days 6,11,14,17 and 20 (before labor) of pregnancy served as five time-points of pregnancy,leptin levels of female mice of the two groups were dynamically monitored during pregnancy,and analyzed at different gestational ages.The data were analyzed by Tukey test of one-way ANOVA.Results (1) Compared with the normal pregnant mice,the levels of glucose tolerance of C57BL/Ksj db/+ female mice were significantly decreased,while the levels of fasting insulin were dramatically increased with the progression of pregnancy [day 6 of pregnancy,(8.6 ± 0.6) mU/L vs (7.5 ±1.1) mU/L; day 11 of pregnancy,(9.8±0.6) mU/L vs (8.5± 1.1) mU/L; day 17 of pregnancy,(10.4±0.8) mU/L vs (9.9±0.5) mU/L; t=1.859,4.056 and 3.078,P=0.085,0.000 and 0.000] and recovered to the pre-pregnancy level after delivery.(2) The level of leptin in serum of C57BL/Ksj db/+ pregnant mice was significantly higher than that at non-pregnant period [pre-pregnancy and days 6,11,14,17 and 20 of pregnancy:(911.0±238.8) ng/L,(1 342.2± 132.3) ng/L,(1 821.9±238.2) ng/L,(1 816.3± 142.3) ng/L,(1 752.4± 126.6) ng/L,and (1 926.4±61.6) ng/L,respectively; t=3.887,8.210,8.161,7.585 and 9.153,P=0.005,0.000,0.000,0.000 and 0.000],but showed no apparent change with the gestational ages after mid-gestation.Conclusion Changes of glycometabolism and the levels of leptin and insulin of C57BL/Ksj db/+ pregnant mice during pregnancy are similar to those of GDM patients,the levels of fasting insulin are dramatically increased with the progression of pregnancy,and return to normal after delivery,the level of leptin is higher than that at non-pregnant period,but is not correlated with the gestational ages.C57BL/Ksj db/+ pregnant mice can be used as the animal model of GDM.
