Morphosis study of points
(1) anatomy observation
(2) histology observation
Anatomy observation
Points and nerves
309 points
152 right on the nerve trunk 49.18%
157 nearly to the nerve trunk 50.81%
361 points
205 points had relation with nerves 56.8%
Anatomy observation
•
same spinal segment
• point
organ
•
•
•
•
Ren Meridian
RN3, RN4, RN6-----kidney
RN8, RN12----stomach and spleen
RN17, RN22----lung
•
•
•
•
•
•
1st line of bladder meridian
BL13----lung
BL15----heart
BL17----diaphragm
BL20----spleen
BL23----kidney
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 observation
ST 36 and some other 34 points were observed by
Blue-spot method
All the blue spot were distributed in the deep
tissues
Then observed the area 1.5 mm around blue spot
Nerves were seen 4 times, blood vessels were seen
26 times
Conclusion: blood vessels had relation with
needling sensation
• 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
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
Speciality of point
• ST36 and BL57 of healthy people
• Post-meal serum gastrin
• ST36
serum gastrin
remarkably
• BL57 changed a little
increased
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
• Observed the surface electric resistance
during menstruation circle
• the resistance increased obviously on SP6
during the stage of discharging an egg
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
Biophysics speciality of point
• Point and surface electricity
• point and surface temperature
Point and surface electricity
• PC6
• non-acupoint-point
on
pericardium
meridian 5 cun above PC6
• 1cm radial to PC6
• 1 cm radial to the non-acupoint-point
• Electric resistance
• 2 points on the meridian < 2 nonmeridian points
Point and surface electricity
• 15 healthy people
• 15 patients with upper respiratory tract
inflammation
• electric resistance determined on both
sides’ points of lung meridian
• healthy people: same
• patients: obvious difference
Point and surface electricity
• 40 normal people
• 40 gastritis patients
• resistance determination on 12 Yuan
points
• normal people: same
• patients: Yuan points of stomach and
spleen meridians were different from that
of others
Point and surface electricity
• 744 times’ observation on 31 rabbits
• 676 lower resistance points
• conclusion: point has the speciality of
lower resistance
Point and surface temperature
• needling on
manipulation
GB34
with
even
• surface temperature
• GB40 and 1 cun below GB34:
increased
• LR4 and LI 3: without any change
Point and surface temperature
• 60 cases suffered from dampness-heat in
liver
• 20 healthy people
• surface temperature
• LR3: patients’ temperature increased
1.55℃ than healthy people
• BL18: patients’ temperature increased
0.70℃ than healthy people
Point and surface temperature
• 38 cases with cancer and ulcer
• back Shu points’ infrared photograph
• coincide rate 95.12%
Diagnosis application of point
• 109 cases had tenderness on RN12, ST21
(right side) and BL50 (right side)
• 107 cases were diagnosed as duodenal
ulcer by X-ray
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
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
