目的调查新疆百岁老人视力、味觉、苯硫脲（ＰＴＣ）味阈及循经感传现象，以探讨百岁老人的不同感觉特点。方法测定 ２７名维吾尔族百岁老人裸眼视力、味觉、ＰＴＣ味阈分布及循经感传现象发生率。结果维吾尔族百岁老人的视力、味觉有明显降低（３４ 只眼除失明、盲眼外的２７只眼平均视力为０．３±０．１；味觉明显减退者占４４，４％）。ＰＴＣ味阈峰值分布无改变，与维吾尔族一般人群完全 一致（双峰分布，味盲峰在１号液，尝味者峰在９号液）。循经感传发生率为６２．５％，明显高于维吾尔族一般人群。结论证实人类有生理 性感觉、遗传性感觉和循经感传觉三种不同的感觉类型。
Objective To investigate the phenomenon of vision, taste, phenylthiourea (PTT) threshold and the meridian sensation in centenarians in Xinjiang to investigate the different sensory characteristics of centenarians. Methods The visual acuity, taste, the distribution of PTC taste threshold and the incidence of meridian sensation were measured in 27 Uygur centenarians. Results The eyesight and taste of Uygur centenarians significantly decreased (34 eyes except blindness, the average eyesight of 27 eyes outside the blind eyes was 0.3 ± 0.1; 44.4% of the patients had obvious taste loss). There is no change in the peak value of the PTC taste threshold, which is consistent with the Uygur general population (bimodal distribution, taste blind peak in liquid No. 1, taste taste peak in liquid No. 9). The incidence of meridian sensation was 62.5%, which was significantly higher than that of Uighur general population. The conclusion confirms that humans have three different sensory types: physiological sensation, hereditary sensation, and sensory perception through the passage.
