Hypersensitivity to cold exposure and emotional stimuli in hand-arm vibration syndrome patients

本文探讨了季节和食物摄入量对手臂振动综合征单手冷暴露试验的影响。夏季手指皮肤温度高于冬季。尤其在冬季，进食后手指皮肤温度高于空腹状态。进食后冷浸时的心率变异性大于空腹时的心率变异性。与15 ℃冷水浸泡3 min相比，10 ℃冷水浸泡10 min的方法显示手臂振动综合征患者与健康对照者手指皮肤温度的差异更大，具有统计学意义。β-TG和β-TG的变化表明，手综合征患者的交感神经系统和肾上腺髓质对情绪刺激和冷暴露具有更大的反应性。

Influences of season and food intake on the cold exposure test of one hand for the hand-arm vibration syndrome were investigated. Finger skin temperature in summer was higher than that in winter. Especially in winter, the finger skin temperature after food intake was higher than that in fasting condition. Heart rate variation during the cold immersion after food intake was larger than that in fasting condition.When comparing to immersing a hand in cold water at 15ﾟC for 3 minutes, method using cold water at 10ﾟC for 10 minutes indicated larger differences of finger skin temperature between hand-arm vibration syndrome patients and healthy controls with statistical significance.Evaluations of heart rate variation and catecholamines, PF4, and beta TG indicated that hand-arm syndrome patients had larger responsibility of the sympathetic nervous system and the adrenal medulla to emotional stimuli as well as cold exposure.
