Anatomy observation• Points and blood and lymphatic vessels
• 309 points• 24 points right on the artery trunk 7.26%• 262 points close to artery and vein trunk 84.36%
• 361 points• 58 near to the artery trunk 16.1%• 87 near to superficial vein 24.7%
• points were observed by electrophoresis• some points right on the local lymph tissues

Anatomy observation• Points and muscles and tendons
• 62.5% of points right on the border of muscles
• the others were on the beginnings and endings of muscles and tendons or in the muscles and tendons

Histology observationST 36 and some other 34 points were observed byBlue-spot methodAll the blue spot were distributed in the deeptissues
Then observed the area 1.5 mm around blue spotNerves were seen 4 times, blood vessels were seen26 times
Conclusion: blood vessels had relation withneedling sensation
![Page 10: General introduction on Acupoint research](https://reader035.fdocuments.in/reader035/viewer/2022062309/568159e3550346895dc72f05/html5/thumbnails/10.jpg)
• LI4 and other 23 points • the areas 1.5mm around the needle
• the small nerve-tract, free nerve endings, small blood vessels and the nerves on their walls, corpuscula lamellosa and nerve trunks
• conclusion: the needling sensation was produced by the co-operation of many structures around the point
![Page 11: General introduction on Acupoint research](https://reader035.fdocuments.in/reader035/viewer/2022062309/568159e3550346895dc72f05/html5/thumbnails/11.jpg)
Speciality of point
• ST36, non-stomach meridian point, and a non-acupoint point
• effect on the frequency and amplitude of gastric peristaltic wave, gastric-tension and gastric emptying
• ST36 was the best
![Page 12: General introduction on Acupoint research](https://reader035.fdocuments.in/reader035/viewer/2022062309/568159e3550346895dc72f05/html5/thumbnails/12.jpg)
Speciality of point
• ST36 and BL57 of healthy people
• Post-meal serum gastrin
• ST36 serum gastrin increased remarkably
• BL57 changed a little
![Page 13: General introduction on Acupoint research](https://reader035.fdocuments.in/reader035/viewer/2022062309/568159e3550346895dc72f05/html5/thumbnails/13.jpg)
Speciality of point
• 37 women in child-birth with weakness of uterus contraction received needling on SP6, GB39 and ST36
• observed the height, width and distance between 2 waves of uterus contraction
• The result showed needling could increase the contraction
• SP 6 had the better effect than GB39 and ST36

Speciality of point
• Rabbits with slow heart rate caused by intravenous injection of acetylcholine
• PC 6 LU 7 a non-acupoint-point
• PC 6 > LU 7 • non-acupoint-point not any effect at all

![Page 25: General introduction on Acupoint research](https://reader035.fdocuments.in/reader035/viewer/2022062309/568159e3550346895dc72f05/html5/thumbnails/25.jpg)
Diagnosis application of point
• 105 cases of gastric diseases (gastritis, ulcer, cancer, etc.)
• tenderness
• ST36 and BL21 had higher positive rates• RN12 and GB34 were lower• BL20, RN13, SP9 and SP8 were lowest
![Page 26: General introduction on Acupoint research](https://reader035.fdocuments.in/reader035/viewer/2022062309/568159e3550346895dc72f05/html5/thumbnails/26.jpg)
Diagnosis application of point• both sides’ Xindaxi and Xinnexi to screen
cancers• positive: the difference of both sides’
temperature > 0.5 ℃ • Accuracy: 77.4%
• Xindaxi: 0.5 cun exterior and inferior to the midpoint of BL36 and BL40
• Xinneixi: 1 cun interior to Xindaxi
