Objectives To compare the hemodynamic effects and ventricular activation sequence associated with the respective pacing of the right ventricular outflow tract (RVOT) and right ventricular apex (RVA). Methods 79 patients with complete atrioventricular block (AVB) or sick sinus syndrome (SSS)to undergo permanent ventricular stimulation either at the right ventricular apex (RVA) (n = 38) or right ventricular outflow tract (RVOT) (n =41) were selected. The left ventricular ejection fraction (LVEF),cardiac index (CI), mitral E/A ratio and QRS duration were recorded before implantation of pacemaker and 6 or 12 months after implantation. Results There were no significant differences in CI , LVEF, E/A between RVOT and RVA pacing(P ＞0. 05). Compared with normal sinus rhythm, the QRS duration was significantly lengthened when pacing at RVOT or RVA (P ＜0. 05). RVA pacing was significantly longer than RVOT in QRS duration (P ＜ 0. 05). Conclusions There was no significant difference with the hemodynamic effect between RVOT and RVA pacing in subject with normal heart function. Compared with RVA pacing, RVOT pacing remained relatively normal ventricular activation sequence.

Objective To explore the effect of comprehensive experiments on clinical practice of internal medicine nursing in the patients with advanced simulation human Simman3G.Methods Two grades of nursing students were selected by random cluster sampling and divided into the experimental group and the control group.The control group used the traditional clinical probation method to carry out clinical probation teaching in Department of internal medicine,the experimental group used the advanced simulation human Simman3G to conduct a comprehensive simulation of teaching before clinical probation.After the completion of the internship the self compiled questionnaire was given to two groups of students to investigate their opinion on the clinical probation.Then we compared,the semester examination results between two groups.Results In the experimental group,the grade of internal medicine nursing was higher than the control group at the end of the semester,P ＜ 0.05.The results of questionnaire survey showed that there was no significant difference between the two groups in the promotion of theoretical knowledge and the two dimensions of the survey of nursing work environment.In the training of clinical thinking,improve nursing skill,communication skill,and the learning interest.At the great harvest of 5 dimensions of probation,the experimental group of students' recognition degree was significantly higher than the control group,P ＜ 0.01.Conclusion Before clinical probation of internal medicine nursing,the application of high-end analog teaching can significantly improve the effectiveness of clinical probation.

Objective To explore the clinical curative effect of locking plate in elderly patients with proximal humeral fractures. Methods Seventy elderly patients with proximal humeral fractures were selected, and all patients were treated with surgical treatment. Among them, application of locking plate was in 35 cases (locking plate group), and application of ordinary steel plate was in 35 cases (ordinary steel plate group). The operation time, intraoperative blood loss, fracture healing time and curative effect between 2 groups were compared. Results The operation time, intraoperative blood loss and fracture healing time in locking plate group were significantly lower than those in ordinary steel plate group: (61.3 ± 5.6) min vs. (78.3 ± 4.2) min, (190.5 ± 11.5) ml vs. (268.5 ± 21.2) ml and (12.6 ± 1.8) weeks vs. (16.5 ± 1.5) weeks, the excellent and good rate was significantly higher than that in ordinary steel plate group: 94.29% (33/35) vs. 74.98% (26/35), and there were statistical differences (P<0.05). Conclusions The curative effect of locking plate in elderly patients with proximal humeral fractures is accurate. Locking plate can be fixed firmly, and it is conducive to early recovery after surgery.
