少冲穴实体解剖OACSTPCD

Objective To investigate the anatomical of the Shaoshang acupoint.Methods ① We summarized the ancient descriptions of the Shaochong acupoint by searching the Duxiu Academic and Chinese Medical Canon database and reviewing ancient texts containing the location of the Shaochong acupoint.② Thirty volunteers were selected,and based on the positioning of the Shaochong acupoint in ancient literature,fingertip pressure was applied on the body surface to de-termine the location of acupoint sensation and then we marked it accordingly.③ Ten volunteers were selected,and based on the acupoint positioning summarized in ancient texts,acupuncture was performed at different depths and directions around the marked area of fingertip pressure to determine the location of the needle tip when acupoint sensation occurred.④ Micro-dissection was conducted on ten sides of fresh adult upper limb specimens based on the Shaochong acupoint location deter-mined by fingertip pressure and acupuncture to explore the anatomical structure of the acupoint.⑤ Ten volunteers were se-lected.When acupoint sensation occurred during acupuncture at the Shaochong acupoint,the location of the needle tip was confirmed using B-ultrasound.⑥ Ten volunteers were selected,and under the guidance of B-ultrasound,the physical structure of the Shaochong acupoint discovered by anatomy was identified,and acupuncture was conducted to verify the po-sition of the Shaochong acupoint.Results ① According to ancient texts,the Shaochong acupoint was located at the end of the ulnar side of the little finger,resembling the tip of a leek leaf.② The location where acupoint sensation appeared up-on fingertip pressure was in the depression between the ulnar side of the little finger's nail corner and the dorsal prominence of the base of the distal phalanx.③ Acupoint sensation was most pronounced when acupuncture was performed on the sur-face of the bone between the ulnar side of the little finger's nail corner and the dorsal prominence of the base of the distal phalanx.④ Microdissection revealed that the Shaochong acupoint was where nutrient blood vessels entered the depression on the dorsal side of the base of the distal phalanx of the little finger.⑤ When acupoint sensation occurred during acupunc-ture at the Shaochong acupoint,the needle tip was located at the hilum of the dorsal side of the base of the distal phalanx of the little finger.⑥ B-ultrasound confirmed that the hilum of the dorsal side of the base of the distal phalanx of the little fin-ger was the anatomical structure of the Shaochong acupoint.Conclusion The anatomical structure of the Shaochong acu-point is located at the hilum of the dorsal side of the base of the distal phalanx of the little finger.
