Objective To explore the screenplay dialogue pattern in the interrogation of the second classroom training effect, so as to improve the quality of the inquiring teaching.Methods 69 five-year students of clinical medicine specialty of Grade 2014 in our university were randomly divided into the control group (34 persons) and the experimental group (35 persons), The students in the control group, during the second class-room training, received the consent of the patient, and informed the patient,to answer the illness according to the truthdo not disclose the diagnosis and treatment after hospitalization and other matters needing attention. Besides, we also arranged for students to conduct repeated bedside inquiry training. While the experimental group carried out the script dialogue model training on the campus. The teacher provided a script for interroga-tion. Students answered in accordance with the principle ofdon't ask don't answer, don't say anything other than the question, don't miss the question, don't answer the question wrongly. SPSS 19.0 was used for statistical analysis, and the comparison of measurement data between groups was performed by t test.Results There was no significant difference between the experimental group and the control group in the inquiry and assessment. The results showed that the training effect of the two groups was basically the same. Through the analysis of various aspects of inquiry, the chief complaint and communication ability of students in the experimental group were better than those in the control group, and the difference was statistically significant, which showed that the script dialogue model promoted students' ability of inducing complaints and their language ability when they did medical history collection.ConclusionTaking screenplay dialogue mode in the second classroom practice is good, which improves the students' enthusiasm, trains their clinical thinking and improves the teaching quality.

Objective In order to find early latent faults and prevent catastrophic failures, diagnosis of insulation condition by measuring technique of partial discharge(PD) in gas insulated switchgear (GIS) is applied in this paper, which is one of the most basic ways for diagnosis of insulation condition. Methods Ultra high frequency(UHF) PD detection method by using internal sensors has been proved efficient, because it may avoid the disturbance of corona, but the sensor installation of this method will be limited by the structure and operation condition of GIS.There are some of electromagnetic (E-M) waves leak from the place of insulation spacer, therefore, the external sensors UHF measuring PD technique is applied, which isn't limited by the operation condition of GIS. Results This paper analyzes propagated electromagnetic (E-M) waves of partial discharge pulse excited by using the finite-difference time-domain (FDTD) method. The signal collected at the outer point is more complex than that of the inner point, and the signals' amplitude of outer is about half of the inner, because it propagates through spacer and insulation slot. Set up UHF PD measuring system. The typical PD in 252kV GIS bus bar was measured using PD detection UHF technique with external sensors. Finally, compare the results of UHF measuring technique using external sensors with the results of FDTD method simulation and the traditional IEC60270 method detection. Conclusion The results of experiment shows that the UHF technique can realize the diagnosis of insulation condition, the results of FDTD method simulation and the result UHF method detection can demonstrate each other, which gives references to further researches and application for UHF PD measuring technique.

Objective:The immunogenicity of DNA vaccine immunogenicity can be improved by fusing antigenic genes to IgG Fc fragment.It is critical for enhancing immunogenicity of DNA vaccine to construct the secreting eukaryotic expressing vector.The purpose of this study is to construct a secreting eukaryotic expressing vector ligated with IgG Fc gene by amplifying human IgG Fc fragment and fusing the fragment with human CD5 signal peptide sequence for highly efficient expression.Methods:Human lymphocytes were isolated from the tonsil obtained by removal surgery.The total RNA of lymphocytes was extracted using Trizol reagent.Human IgG Fc cDNA was amplified by RT-PCR from lymphocytes and then inserted into pMD-18T vector.The Fc encoding sequence fused with CD5 signal peptide(sp) sequence was constructed by cross PCR using Fc fragment and CD5sp sequence and cloned in pcDNA-CD5 plasmid as the template.CD5sp-Fc fragment was inserted into pcDNA3.1 expressing vector to construct the pcDNA-CD5sp-Fc plasmid.The plasmids were transfected into HEK293T cells mediated by calcium phosphate.Western blot was used to detect expressed Fc protein in cultural supermatant of the cells.Results:The amplified sequence of human IgG Fc was consistent with that previously published.The secretory expression of Fc in HEK293T cells was achieved and the expressing level reached 50 ?g/106 cells at 48 h culture after transfection.Conclusion:The human IgG Fc gene is amplified by RT-PCR methods and the secretory expression of Fc gene mediated by CD5 signal peptide in 293T cells is achieved.The results provide a experimental basis for further construction of antigen genes fused to IgG Fc fragment and investigation on DNA vaccines and Fc as a biological adjuvant.

Objective To study effects and other related problems of surgery for patients with cervical spine fracture and ankylosing spondylitis.Methods Twelve patients with cervical spine fracture and ankylosing spondylitis were treated with surgery from April 1986 to April 2004.All eases were studied retrospectively.They were followed up for an average of 67.5 months and their complete clinical data were kept.The neurological function was evaluated by ASIA (American Spinal Injury Association) impairment scale,and the image analyzing software (Image-Pro Plus 5.1) was used to measure the angles of superior and inferior vertebral bodies of the fusion segment at flexion and extension positions.The difference between flexion and extension angles,?,served as the parameter of interspinal movement.According to the definition of spinal fusion by FDA (Food and Drug Administration),the?≥4?was considered as nonfusion.Other related problems were discussed by descriptive study.Results The average improvement in the nine patients with neurological injury was 1.3 ASIA grades.The injured segments in 10 cases were treated with fusion,of whom nine were fused by internal fixation.The fusion rate was 100%.Three cases were scheduled to have laminoplasty,but two had to receive laminectomy instead because of intraoperative complete fracture at the hinged side.Ten patients were complicated by insufficient function of major organs preop- eratively,and endotracheal intubation was difficult to perform in eight cases.Postoperative complications occurred in three cases,but fortunately healed completely.There were no deaths or fatal complications.Conclusions The neurological function can be improved by surgery for patients with cervical spine fracture and ankylosing spondylitis. Although the cervical spine is instable for most of the patients,fusion with internal fixation is indicated and can be successful.Those who had preoperative systemic diseases are likely to suffer from postoperative complications.The difficult endotracheal intubation is a common intraoperative problem.
