摘要
目的研究中国正常老年人和年轻人不同部位皮肤共振传导特性。方法152例年龄20～40岁的正常年轻人和64例年龄60～88岁的正常老年人参加本研究。利用Reviscometer RVM600分别于左手背、左前臂屈侧、前额及左眼外眦处测量不同方向皮肤共振传导时间（CRRT）。结果CRRT因测量部位和方向的不同而不同。在前臂，除在2—8点方向外，其他各方向老年人的CRRT大于年轻人：0—6点方向，f=7．46；1—7点方向，f=3．38；3—9点方向，t=3．88；4—10点方向，f=6．82；5—11点方向，卜7．42，P值〈0．01或〈0．05。在手背部位，除在3—9点方向外，其他各方向年轻人的CRRT则大于老年人：0—6点方向，t=4．53；1—7点方向，t=5．71；2—8点方向，t=2．74；4—10点方向，t=2．67；5—11点方向，t=4．20，P值均〈0．01或〈0．05。在前额部位，年轻人的CRRT与老年人差异无统计学意义。在眼外眦部位的1—7点和2—8点方向，年轻人CRRT大于老年人：1—7点方向，t=3．18，P〈0．01；2—8点方向，k5．11，P〈0．01。男女之间各部位CRRT没有明显差异。结论CRRT因年龄、方向及部位的不同而不同，性别对CRRT没有明显影响。
Objective To study the cutaneous resonance running time （CRRT） in normal young and old Chinese people. Methods A total of 152 young subjects aged 20 - 40 years and 64 old subjects aged 60 - 88 years were enrolled in this study. A reviscometer RVM600 was used to measure CRRT at various directions on the left dorsal hand, forearm, forehead and outer canthus. Results CRRT varied with body sites and measuring directions. On the forearm, CRRT at all directions except 2 - 8 o＇clock were higher in old than in young subjects （0 - 6 o＇clock direction, t = 7.46, P 〈 0.01; 1 - 7 o＇clock direction, t = 3.38, P 〈 0.01; 3 - 9 o＇clock direction, t = 3.88, P 〈 0.05; 4 - 10 o＇clock direction, t = 6.82, P 〈 0.01; 5 - 11 o＇clock direction, t = 7.42, P 〈 0.01 ）. On the dorsal hand, CRRT at all directions were higher in young than in old subjects （0 - 6 o＇clock direction, t = 4.53, P 〈 0.01; 1 - 7 o＇clock direction, t = 5.71, P 〈 0.01; 2 - 8 o＇clock direction, t=2.74, P 〈 0.01; 4 - 10 o＇clock direction, t = 2.67, P 〈 0.01; 5 - 11 o＇clock direction, t= 4.20, P〈 0.01）. On the forehead, there was no significant difference in CRRT between young and old subjects. And on the outer canthus, CRRT at 1 - 7 and 2 - 8 o＇clock directions were higher in young than in old subjects （1 - 7 o＇clock direction, t = 3.18, P 〈 0.01; 2 - 8 o＇clock direction, t = 5.11, P 〈 0.01）. There was no statistical difference in CRRT between males and females. Conclusion CRRT varies with age, body sites, measuring directions, but not with gender in normal Chinese people.
