Objective To explore the effect of the situation-background-assessment-recommendation mode of SBAR communication on the clinic communication competence of nurses.Methods 20 obstetric nurses were selected for the study,the mode of SBAR communication was applied to the communication between doctors and nurses,nurses and nurses,nurses and patients.The clinic communication competence was investigated by the questionnaire of clinic communication competence before and after using the mode of SBAR communication.Results The scores of the clinic communication competence after using the mode of SBAR communication was (56.41±6.32),which was higher than that before the implementation,(48.15±5.26),there were statistically significant differences,P＜0.05.The scores of communication competence between doctors and nurses,between nurses and nurses,between nurses and patients were higher after implementation of SBAR compared with those before,(4.06±1.26)vs.(2.62±1.31),(4.05±1.41)vs.(3.59±1.46),(3.98±1.32) vs.(3.36±1.36),there were statistically significant differences in all of them,P＜ 0.05.Conclusions SBAR communication mode helps improve clinic communication competence of nurses,promote the establishment of harmonious team between doctors and nurses,ensure patients' safety and quality of care.

0.05 ) in baseline study. The atrial pressure in AF group had higher increase than no AF group. (3) there was greater AERP dispersion in patients with PAF than that in those without PAF during baseline study and PSVT (P

Objective To investigate the relationship between serum cystatin C (Cys C) level and the occurrence of in-stent restenosis after coronary drug-eluting stent implantation.Methods A retrospective analysis of coronary drug-eluting stent implantation was curried out in 592 patients.All patients were from Shengjing Hospital of China Medical University by coronary angiography,and were divided into restenosis group (142 cases) and non restenosis group (450 cases).The Cys C levels before and after surgery and follow-up angiography were analyzed.The biochemical indicators,and transcatheter arterial restenosis were analyzed.Results Either before or after operation and follow-up angiography,serum cystatin C levels were higher in restenosis group patients than that in non restenosis group [before operation:(1.622 ± 1.063) mg/L vs (1.369 ± 0.860) mg/L;after the operation:(1.769 ± 1.062) mg/L vs (1.458 ± 0.883) mg/L;review:(1.924 ± 1.085) mg/L vs (1.440 ± 0.874) mg/L;P ＜ 0.05].Multivariate COX regression analysis showed that serum cystatin C level was an independent risk factor of in-stent restenosis in drugeluting area (P ＜ 0.05).Conclusions The serum cystatin C level is closely related to in-stent restenosis in drug-eluting stents area.High level of serum cystatin C is an independent risk factor of in-stent restenosis after drug-eluting stents implantation.

Objective To investigate the effect of RNA interference plasmids of cysteine-rich 61(Cyr61) on hyperplasia of vascular smooth muscle cell (VSMC) in rats.Methods The plasmids containing the short hairpin RNA (shRNA) of Cyr61 were constructed.Expression of Cyr61 mRNA and protein were detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting.The hyperplasia of VSMC was assessed by MTT.DNA synthesis was measured by incorporating ~3H-TDR.Plasmid construction was confirmed by DNA sequencing.Results PCyr61-shRNA transfection significantly decreased the level of mRNA and protein of Cyr61 in VSMC.The cell number,optical density and concentration of DNA in pCyr61-shRNA group were significant decreased(P

Objective To provide the anatomical data for single-nostril transsphenoidal microsurgery for pituitary adenoma.Methods Microanatomic structures were observed and measured in 20 cadaveric a- dults heads.Results(1)The diaphragmal opering was 5 mm or greater broad in 90%.The mean thick- ness of the diaphragma sellae was (0.18?0.08)mm.(2) A sphenoid sinus with complete pneumatization was named as all-sellae type,its percentage in all specimens was 85%,85% sphenoid sinus had middle sep- tum of which only 18.8% located in the medial sagital section.(3)The meant thickness of the sellar floor was (0.81?0.34) mm,70% of which were not more than 1 mm.Of the sellar floors,that the shape was flatness reach 15%.(4) The relationship between ICA and sphenoid sinus had two aspects,one was to be mutually apart (55%),the other was to communicate (45%),which formers carinae on the lateral wall of the sphe- noid sinus,espeially in the superior surface of posterior part.The relationship between optic nerve and sphe- noid sinus,one was to be mutually apart (27.5%),the other was to communicate (72.5% ),which formers carinae on the lateral wall of the sphenoid sinus,especially in the superior surface of anterior part.(5) Three main types of the intercavernous sinus were the anterior intercavernous sinus,present in 80%,the inferior in- tercavenous sinus (25%),and the posterior intercavenous sinus (15%).Conclusion The knowledge of the anatomy of the sellar region and sphenoid sinus is helpful to safe operation in the single-nostril transsphe- noidal approach for pituitary,adenoma microsurgery.

Objective:To observe the influence of ginsenoside Rg1 on transcriptional activation of NF-κB induced by hydrogen peroxide (H_2O_2) in 293T cell,and probe into the antioxidant mechanism of ginsenoside Rg1.Methods:In the experiment,cells was exposed to H_2O_2 after pretreatment with Rg1,cell proliferation and cytotoxicity studies were detected by MTT and Trypan blue.The quantities of generation of intracellular reactive oxygen species (iROS) was analyzed by flow cytometric analysis measured with fluorescent probe 2,7-dichlorofluorescin diacetate (DCFH-DA).NF-κB-responsive element-luciferase reporter gene was transfected and dual-luciferase cis-reporting systems were used to assay the transcriptional activity of NF-κB under the stimulated circumstance of oxidative stress induced by H_2O_2.Results:The results of MTT showed that ginsenoside Rg1 apparently protected the proliferation of 293T cell,which were repressed by H_2O_2 (P＜0.05).The results by trypan blue showed that H_2O_2 stimulated substantial cytotoxicity.This effect was markedly attenuated by treatment with ginsenoside Rg1.Oxidant production,measured as the fluorescence of dichlorofluorescein,was significant increased by 40%-50% through H_2O_2 stimulation.The decrease in iROS generation was significant blocked by 35%-40% through Rg1 and antioxidant.The relative luciferase reporter assay of NF-κB was apparently improved by H_2O_2-induced(P＜0.05),but Ginsenoside Rg1 significantly repressed the relative value of luciferase (P＜0.05).Conclusion:Ginsenoside Rg1 has the obvious protective function from the damage of oxidative stress damage,whose possible mechanism is to eliminate excessive free radicals of the cells effectively,to reduce transcriptional activation of nuclear factor kappa B(NF-κB),and subsequently to suppress the NF-κB circuit activation.

Objective To study the imaging features of primary mediastinal cysts,and to improve the diagnostic ability of these diseases.Methods The imaging findings of primary mediastinal cysts proved by pathlolgy in 42 cases were retrospectively.All of cases underwent posteroanterior and lateral views of chest.The plain and contrast-enhanced CT scans were performed in 28 and 15 cases.MRI examination was done in 6 cases.The location,size,shape,density,edge,wall and adjacent structures of the primary mediastinal cysts were observed.According to imaging features all of cases was divided into typical group and atypical group.Results The mediastinal cysts were located in anterior mediastinum in 28 cases,in middle mediastinum in 7 cases,in posterior mediastinum in 7cases.Bronchogenic cyst was in 9 cases.Cystic lymphangioma was in 4 cases.Thymic cyst was in 11 cases.Pericardial cyst was in 5 cases.Mature cystic teratoma was in 13 cases.The typical group was in 38 cases.The atypical group was in 4 cases.Conclusion 90% of the typical primary mediastinal cysts can be diagnosed.The final diagnosis of the atypical group desponds on pathology.
