Objectives: To explore the influence of exercise training on the arterial baroreflex sensitivity （BRS）and correlation between blood pressure and BRS in spontaneously hypertensive rats (SHR). Methods: Male SHR（n=20）and normotensive Wistar rats（n=20）were randomly assigned to normality group and exercise group, n=10 in each group. Rats in two exercise groups received treadmill training at a speed of 20 m/min for 60 min/d, 6 d/w for eight weeks. Systolic blood pressure (SBP) and heart rate (HR) were measured using a tail-cuff method in a conscious state. Intravenous injections of phenylephrine (PE) and sodium nitroprusside (NP) were used to induce depressor and pressor reflex respectively. The ratio of HR over mean arterial pressure (MAP) (HR /MAP) after administration of PE or NP was regarded as an index of depressor reflex sensitivity (BRS-PE) and pressor reflex sensivity (BRS-NP). Results: After eight-week exercise training, compared with SHR normality group, there were significant reduction in resting SBP [(180±8.5) mmHg vs. (163.6±10.7) mmHg] and in HR [(368.4±13.3) beats/min vs. (345.0±9.8) beats/min] in SHR exercise group, P<0.01 both. However, there was no significant difference in resting SBP between Wistar exercise and normality groups (P>0.05), compared with Wistar normality group, there was significant reduction in HR [(362.2 ± 13.0) beats/min vs. (343.9 ± 10.2) beats/min, P <0.05] in Wistar exercise group. Compared with SHR normality group, there were significant rise in BRS [BRS-PE: (0.89 ± 0.13) bpm/mmHg vs. (1.32 ± 0.22) bpm/mmHg, BRS-NP： (0.60± 0.09) bpm/mmHg vs. (1.21± 0.26) bpm/mmHg, P<0.01] in SHR exercise group, but still lower than those of Wistar normality group [BRS-PE: (1.96±0.23) bpm/mmHg, BRS-NP: (1.32±0.17) bpm/mmHg]. Pearson linear correlation analysis indicated that MAP was significantly inversely correlated with BRS (r=-0.734, P<0.01) in SHR normality and exercise group. Conclusion: Exercise training may significantly decrease SHR blood pressure; it is related to improved baroreflex sensitivity induced by exercise, indicating that enhanced baroreflex may be an important mechanism of exercise therapy in hypertensive patients.

Objective To discuss the application effects of trinitarian visualization teaching model in endoscopy reprocessing teaching practice. Methods Subjects in the study were divided into the trinitarian visualization teaching group (n=40) and the traditional teaching group (n=43) by random number table method; Compliance and credibility rating of endoscope reprocessing procedures were compared between 2 groups. 2 weeks after training, objectives were examined and assessed by questionnaires separately. Results Compliance of the trinitarian visualization teaching group was higher than the traditional teaching group (χ2=10.501, P=0.033). The trinitarian visualization teaching group had a higher rating in compliance, with 47.47 credibility points, theory test (93.79 ± 3.81) points and 93.02%(40/43) of operation pass. The traditional teaching group had a credibility point of 43.68 credibility points, with theory test (85.25±3.14) points and 77.50%(31/40) of operation pass. Significant difference between the two groups were statistical significant (t=4.84 and 11.097, χ2=4.038,P<0.01 or 0.05). Conclusions The trinitarian visualization teaching model can be used to improve the reprocessing training quality, to save time and human resource and to reach the training demand.
