医学院高龄教师植物神经功能与血压的关系

目的　探讨医学院校高龄教师植物神经功能状态及其与血压的相互关系。方法　将７０ 名医学院高教龄教师和８２对照组人员进行心率变异性分析，并将血压与心率变异性指标进行相关分析。结果　反映交感神经功能（ＬＦ）和迷走－ 交感的均衡性（ＬＦ／ＨＦ）指标均显著高于对照组，而反映迷走神经功能指标（ＳＤＡＮＮ、ＨＦ）则显著低于对照组（ Ｐ＜ ０．０５ 或Ｐ＜０．０１）；ＳＢＰ、ＭＡＢＰ分别与ＳＤＡＮＮ 呈显著的负相关、与ＬＦ／ＨＦ呈显著的正相关（Ｐ＜ ０．０５ 或Ｐ＜ ０．０１）。结论　长期紧张、高负荷的工作环境，使医学院高教龄教师交感神经功能明显增高、迷走神经功能明显降低，继而引起血压水平（以ＳＢＰ为主）及高血压病的患病率高于同年龄、同工龄的人群

The relationahips between the autonom ic functtons and blood pressure in aged teachers in m edicalcollege

Objective To explore the effects ofthe autonom ic function and its relation with blood pressure ofold-aged teachers in higher education.Method The heartrate variability w as m easured in 70 aged teachers and com pared with that in control group; relationships betw een the heart rate variability and blood pressure w ere analyzed. Results LF,LF/HF in- creased and SDANN ,HFdecreased greatly than thatin controlgroup( P< 0.05,P< 0.01); SBP,MABPw ere negtively re- lated to SDANN and positively related to LF/HFrespectively(P < 0.05, P < 0.01). Conclusion Long-period nervousness and high-pow erload in teaching olcupation in m edicallollege,can dcvelop the function ofthe sym pathetic nerves and incvease the levelofblood pressure ( espacially SBP) and resultin the increasing ofthe PRH in teachers
