《黄帝内经·素问·标本病传论》
胃病则心腹部胀满，五日后病邪传于肾，发生小腹、腰脊疼痛，小腿发酸；再过三日病邪传入膀胱，发生背脊筋骨疼痛，小便不通；再过五日病邪传于脾，则身体沉重；再过六日不愈就要死亡；冬天死于半夜之后，夏天死于未时。
胃病胀满，五日少腹腰脊痛、胻酸，三日背𦛗筋痛、小便闭，五日身体重，六日不已，死，冬夜半后，夏日昳。
The stomach disease causes abdominal distension and feeling full; after five days the disease spreads to the kidney, causing pain in the lower abdomen, the lower back and lumbar spine, and soreness in the calves; three more days later, the disease spreads to the bladder, causing pain in the back and spine and difficulty urinating; five days later, the disease spreads to the spleen, causing the body to feel heavy; if it is not cured in another six days, the patient will die; in winter, the death occurs after midnight, in summer, it occurs in the wei hour.
