2.2. Rapports et coupes anatomiques

Cutaneous nerves have vascular branches (VBs) that reach the arteries and are thought to be involved in arterial constriction. We aimed to examine the anatomical and histological relationship between the VBs of a cutaneous nerve in the foot and the acupuncture point LR3 (Taichong), which is a depression between the base of the first and second metatarsal bones on the dorsum of the foot and is a source point of the foot. We examined 40 cadaver feet to assess the distribution areas of the VBs of the medial branch of the deep peroneal nerve (MBDPN). MBDPNs were distally followed to identify the point where the VBs reached the arteries. The distance between the point and LR3 was measured. Sympathetic fibers in the VBs were histologically observed using tyrosine hydroxylase (TH) immunostaining. The VBs of the MBDPNs reaching the dorsal pedis arteries were observed in all specimens (100%). The mean distance between LR3 and the point where the VBs of the MBDPN reached the arteries was 3.2 ± 2.6 mm. Among the VBs, 70% were distributed proximal to LR3. Moreover, TH-positive fibers were present in the VBs. These findings revealed that a part of the MBDPN distributed the dorsal pedis artery and contained sympathetic fibers. We also found that the distribution area of the VBs was close to LR3. Our study provides anatomical evidence that LR3 is a specific area and its stimulation would be useful for treating peripheral circulatory failure.

5.4. Revues des indications

The visualization of the indications of the acupoints on a body map. Eight Source points representing the three meridian systems (Foot-Yin, Hand-Yin, and Hand-Yang meridian) and the indications of each acupoint (tf-idf value)were visualized on a human body template (Jung 2015).

Objective To observe the anti-hypertension effect of selecting Taichong (LR3) as the major point plus its common-meridian acupoint on the spontaneous hypertension rat (SHR), and to explore the effect of acupoint compatibility on the action of acupoints. Method Ninety SHRs were randomized into a model group, a non-acupoint group, Taichong group, Neiguan (PC6) group, Taichong plus Neiguan group, and Taichong plus non-acupoint group, 15 rats in each group. The acupuncture needles were retained in acupoints for 30 min, once every day, 15 times in total; the model group didn't receive acupuncture treatment. The blood pressure was examined on the day 1, 3, 7, and 15 of the acupuncture treatment. Result The non-acupoint group didn't show significant anti-hypertension effect. On the day 3, 7, and 15 of the acupuncture treatment, the reductions of systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial blood pressure (MBP) of Taichong group, Neiguan group, Taichong plus non-acupoint group, and Taichong plus Neiguan group were significantly different from those ofthe model group (P<0.01,P< 0.05); on the day 15, The reductions of SBP, DBP, and MBP of Taichong plus Neiguan group were superior to those of Taichong group, Neiguan group, and Taichong plus non-acupoint group (P<0.01 ,P<0.05). On the day 1, 3, 7, and 1 5, the reductions of SBP, DBP, and MBP in Taichong plus Neiguan group were statistically significant (P<0.01,P<0.05), and the reductions on the day 15 were significantly better than those on the day 1, 3, and 7 (P<0.01). Conclusion Acupuncture at Taichong and Neiguan has better anti-hypertension effect than acupuncture at single acupoint or at Taichong plus non-acupoint. Meanwhile, it's found that the anti-hypertension effect of acupuncture is an accumulative effect.
