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 epidemic situat ion of the dental fluorosis among the people in Tianjin area.Methods　With the method of random sampling we investigated epidemic situation of the dental fluorosis among the people aged 12 to 15 in Tianjin area.Results　The minimum patient's rate for this disease among those aged 12 to 15 is 32.11 percent while the maximum is 78.09 percent.The l owest dental fluorosis index is 0.851 and the highest is 1.923.The patient's rate and the index are both higher than the average rate and index of the whole cou ntry.Conclusions　Tianjin is one of the areas where the dental fluorosise epidemic mostly occurs.

Objective To study the influence of UPPP on resonance characteristics of four resonance cavity in patients with OSAHS .Methods Using multi-channel voice analysis system to test the cavity resonance character-istics and energy distribution of 36 OSAHS patients (including pre - and post -operative) and 36 normal males when they speak /a:/.The frequency spectrum was 4 000Hz(FR1 ,FR2 ,FR3 ,FR4 ) .Results FR2 energy values of the head cavity and mouth cavity of OSAHS patients heighten significantly after UPPP (P<0 .05);FR1 energy val-ues of head ,mouth and thoracic cavity were higher than that of in normal males'after UPPP(P<0 .05) .FR2 ,FR3 , FR4 energy values of head cavity ,FR2 ,FR3 energy values of mouth cavity ,FR2 energy values of thoracic cavity were lower than those of in normal males'after UPPP(P<0 .05) .Conclusion UPPP surgery removes the obstruction of the upper airway of OSAHS patients and changes the morphology of the pharynx ,thas changes the resonance charac-teristics of the head cavity and oral .

Objective To study the effects of 6-week aerobic treadmill exercise on the genes expression in skeletal muscle of C57BL/6 mice.Gene array was performed and the data was analyzed to evaluate the adaptive changes at gene level caused by exercise.Methods Twenty male C57BL/6 mice were randomly divided into two groups:control group(C) and aerobic exercise group (E).The mice from group E were forced to run on treadmill for 6 weeks.After 6 weeks,all mice were fasted for 16 hours,and then sacrificed.Their flexor muscle was removed.4 samples from each group were analyzed with gene chips to dissect the differentially expressed genes between the two groups.Results Our results showed that 723 genes were differentially expressed in E group as compared with C group after the 6 weeks aerobic exercise,among which 510 genes were up-and 213 down-regulated.There were 6 differentially expressed calcium signaling genes and 2 ofwhich(Gnall and Pdgfra) were up-regulated,while the others(Phka1,Picd4,RYR1 and Ppid)were down regulated.

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.
