Note: Both hands were put into 4 °C ice water for 20 s, then removed and quickly dried (the patients were instructed not to rub their hands), and the skin temperature of each fingertip of the second to fourth fingers of both the hands was immediately measured and recorded as T0; the fingers did not touch any object, and naturally recovered at room temperature for 3 min, then re-measured and recorded the skin temperature of each fingertip, which was recorded as T3; T3-T0 of each finger of each hand was calculated, respectively, and the mean was obtained, which was recorded as δT
