RESUMO
Objective:To explore the effect of applying standardized patient teaching based on Calgary-Cambridge communication model in nurse patient communication training for junior college interns, and to enrich the teaching methods of nurse patient communication training in domestic medical institutions.Methods:This study was a quasi-experimental study. In July 2022, 78 students were selected from 335 junior college interns in the First Affiliated Hospital of Shandong First Medical University by random coding method, and were randomly divided into the experimental group (39 students) and the control group (39 students) by lot. The control group received routine training. The experimental group received standardized patient teaching based on Calgary Cambridge communication model: teaching the key points of communication, guiding demonstration based on Calgary Cambridge communication model, and guiding reflection and exploration. The nurse patient communication ability, nurse patient communication practice skills, communication self-efficacy, and teaching satisfaction of the two groups of interns were compared between the two groups after 8 weeks of training.Results:After training, the total score of nurse patient communication ability evaluation in the experimental group was (91.41 ± 5.35) points, higher than that in the control group (88.08 ± 7.40) points, there was significant difference ( t=2.24, P<0.05); after training, the communication self-efficacy score of the experimental group was (30.21 ± 4.28) points, higher than that of the control group (27.94 ± 5.09) points, there was significant difference ( t=2.09, P<0.05); the total score of communication practice skills in the experimental group was (173.59 ± 18.48) points, higher than that in the control group (158.44 ± 15.57) points, there was significant difference ( t=3.82, P<0.05); the total score of communication teaching and training satisfaction in the experimental group was (16.77 ± 2.94) points, higher than that in the control group (15.22 ± 1.90) points, and there was significant difference ( t=2.68, P<0.05). Conclusions:The standardized patient teaching based on Calgary Cambridge communication model can effectively improve the practical skills of nurse patient communication of junior college interns, and promote the improvement of their nurse patient communication self-efficacy, which is conducive to the improvement of nurse patient communication ability junior college intern.
RESUMO
This study aims to propose a multifrequency time-difference algorithm using spectral constraints. Based on the knowledge of tissue spectrum in the imaging domain, the fraction model was used in conjunction with the finite element method (FEM) to approximate a conductivity distribution. Then a frequency independent parameter (volume or area fraction change) was reconstructed which made it possible to simultaneously employ multifrequency time-difference boundary voltage data and then reduce the degrees of freedom of the reconstruction problem. Furthermore, this will alleviate the illness of the EIT inverse problem and lead to a better reconstruction result. The numerical validation results suggested that the proposed time-difference fraction reconstruction algorithm behaved better than traditional damped least squares algorithm (DLS) especially in the noise suppression capability. Moreover, under the condition of low signal-to-noise ratio, the proposed algorithm had a more obvious advantage in reconstructions of targets shape and position. This algorithm provides an efficient way to simultaneously utilize multifrequency measurement data for time-difference EIT, and leads to a more accurate reconstruction result. It may show us a new direction for the development of time-difference EIT algorithms in the case that the tissue spectrums are known.
RESUMO
Objective To investigate the effects of rapamycin on the biological behaviors of human non-Hodgkin lymphoma Raji cells with different concentrations and time, and to explore its mechanism. Methods Different concentrations (0, 10, 50, 100, 250, 500 nmol/L) of rapamycin were used in Raji cells for 24, 48, 72 h respectively. The apoptosis of Raji cells was detected by using CCK-8 method, and flow cytometry was used to detect the cell apoptosis and cycle of Raji cells. The enzymatic activity of Caspase-3 and Caspase-9 in Raji cells was detected by Caspase-3 and Caspase-9 activity testing kit. The expressions of bcl-2, p53 protein and mRNA were detected by Western blot method and reverse transcription-polymerase chain reaction (RT-PCR). Results The proliferative inhibition rate of Raji cells was increased from (23.7 ± 4.2)％to (51.7±3.7)％, the cell apoptosis rate was increased from (4.9±1.9)％to (20.5±1.5)％, the proportion of G0/G1 was increased from (40.8±1.4) ％to (63.6±1.7) ％, the Caspase-3 enzyme activity of Raji cell in 24 h was increased from 0.16±0.05 to 1.08±0.04, Caspase-9 enzyme activity was increased from 0.19±0.04 to 1.34± 0.06 after 24 h with the increasing concentration of rapamycin from 0 nmol/L to 500 nmol/L (P<0.01). The mRNA of bcl-2 was decreased from 0.90±0.03 to 0.46±0.03, and mRNA of p53 was increased from 2.51±0.41 to 5.85±0.21. The protein expression of bcl-2 was reduced and the protein expression of p53 was increased. The experimental results of Raji cells in 48 h and 72 h were consistent with the experimental results of 24 h. Conclusion Rapamycin may inhibit the proliferation of Raji cells through Caspase-3, Caspase-9, bcl-2, p53 and induce its cell apoptosis.
RESUMO
Objective To investigate the related prognostic factors of stage Ⅳ gastric cancer.Methods The clinical data of 248 patients with stage Ⅳ gastric cancer and intact follow up data in the Tumor Prevention and Treatment Center of Sun Yat-Sen University from 2000 to 2010 were retrospectively summarized.The twelve clinicopathological parameters served as the observation indicators,including age,sex,body mass reduction,H b,CEA,CA19-9,Borrmann type,tumor location,tumor size,pathological pattern,operative mode,metastatic sites and therapeutic model.The survival curve was drawn by using the Kaplan-Meier method.The median survival time was calculated.The univariate analysis was conducted with Log-rank test.The prognosis multivariate analysis was conducted by the Cox's proportional hazards regression analysis.Results MST in the patients of whole group was 254 d.The univariate analysis showed that sex,Borrmann type and therapeutic mode were the related factors afecting gastric cancer prognosis,while the Cox regression model revealed that above 3 indicators were also independent factors affecting the prognosis of the patients with stage Ⅳ gastric cancer in this group(P＜0.05).Conclusion The treatment mode is an important independent factor affecting the survival of stage Ⅳ gastric cancer,the translational medicine model of palliative chemotherapy combined with palliative operation conduces to improve the prognosis in the patients with stage Ⅳ gastric cancer.
