OBJECTIVE: To observe the anatomic structure of the Five Shu-acupoints: “Shaoze” (SI 1) ,”Qiangu“ (SI 2), “Houxi” (SI 3),”Yanggu“ (SI 5) and “Xiaohai” (SI 8) regions of the Taiyang Meridian in the rabbit's forelimb. METHODS: Thirty rabbits (half male and half female) were used in the present study. The Five Shu-acupoints regions were located first based on the atlas of rabbits, stimulated by needling and confirmed later by using an electronic acupoint detector. Under anesthesia, the rabbit was perfused with warm normal saline via the common carotid artery and the internal jugular vein, followed by arterial perfusion of dental base acrylic resin powder(30 g), dibutylphthalate(6 mL), red couring agent liquid for denture acrylic and acetoacetate (2 mL), respectively; and venous perfusion of 30% gelatin (filtered) and black ink (filtered) and formaldehyde (8%). After fixing in 8% formaldehyde for 10 days, the rabbit's forelimb containing the aforementioned Five Shu-acupoints were carefully dissected layer by layer, followed by observing the local anatomic structure under microscope. RESULTS: The superficial layers of these acupoint regions mainly contained the basilic vein and its branches, and the superficial branch of the ulnar nerve. The deep layers chiefly comprised of the ulnar artery, the ulnar vein and their branches, and the ulnar nerve. CONCLUSION: In “Shaoze”(SI 1 ), “Qiangu” (SI 2), “Houxi” (SI 3), “Yanggu” (SI 5) and “Xiaohai” (SI 8) acupoint regions, the ulnar artery, basilic vein, ulnar vein and their branches, the ulnar nerve and its superficial branches are found, which constitute the morphological basis of the five acupoints of the Hand-Taiyang Meridian for treating some related clinical disorders

OBJECTIVE: To observe the effect of electroacupuncture (EA) stimulation of “Xiaohai” (SI 8) and “Xiajuxu” (ST 39) on serum TNF-α and duodenal high mobility group protein B 1 (HMGB 1) levels in rats with duodenal ulcer (DU), so as to analyze its underlying mechanism in improving DU. METHODS: Forty SD rats were randomly divided into normal control, model, Xiaohai (SI 8) and Xiajuxu (ST 39) groups (n=10 in each group). The DU model was established by intramuscular injection of 10% Cysteamine hydrochloride (300 mg/kg), followed by taking water containing 1% Cysteamine hydrochloride for 48 h. EA (10 Hz/50 Hz, 1-3 mA) was applied to bilateral SI 8 and ST 39 for 30 min, once a day for 10 days. The DU score (0-5 score) was evaluated according to Moraes' method. Serum TNF-α content was determined by ELISA and duodenal HMGB 1 expression was measured by immunohistochemistry. RESULTS: Compared to the normal control group, the DU score, serum TNF-α content, and duodenal HMGB 1 expression level of the model group were significantly higher (P<0.01). Following EA intervention, the increased DU score, serum TNF-α content, and duodenal HMGB 1 expression level were considerably down-regulated in the two EA groups in comparison with the model group (P<0.01, P<0.05) except HMGB 1 in the SI 8 group (P>0.05), and the effect of EA of “Xiajuxu” (ST 39), the lower-He point, was remarkably superior to that of “Xiaohai” (SI 8) in reducing DU score and TNF-α content (P<0.01). CONCLUSION: EA stimulation of SI 8 and ST 39 can improve duodenal ulceration in DU rats, which may be related to its effect in down-regulating serum TNF-α and duodenal HMGB 1 expression. The therapeutic effect of ST 39 is markedly better than SI 8 in relieving duodenal ulceration.]
Objective To investigate the effect of electroacupuncture at points Xiaohai and Xiajuxu on the expressions of tumour necrosis factor-α (TNF-α) and choline acetyltransferase (ChAT) in serum and nicotinic acetylcholine receptorα 7 (α 7 nAchR) in duodenal tissues in a rat model of duodenal ulcer (DU) and preliminarily explore the relative specificity of He-Sea point in “treating visceral diseases with He-Sea point”.Methods Forty healthy SD rats were randomized into blank (A), model (B), Xiaohai © and Xiajuxu (D) groups, 10 rats each. A rat model of DU was made by subcutaneous injection of 10% cysteamine hydrochloride at the right buttock. After successful model making, group C was given electroacupuncture at point Xiaohai and group D, at point Xiajuxu. Duodenal tissue ulcer was macroscopically observed and scored in every group of rats. Rat serum expression of TNF-α was determined by double antibody sandwich enzyme-linked immunosorbent assay (ELISA); rat serum expression of ChAT, by ultraviolet spectrophotometry & colorimetry; rat duodenal expression ofα7 nAchR, by Western blot.Results After model making, the duodenal ulcer score was significantly higher in groups B, C and D than in group A (allP<0.01) and significantly lower in groups C and D than in group B (bothP<0.01) and in group D than in group C (P<0.01). TNF-α expression was significantly higher in group B than in group A (P<0.01) and significantly lower in groups C and D than in group B (bothP<0.01) and in group D than in group C (P<0.01). ChAT expression tended to increase in group C compared with group B but there was no statistically significant difference (P>0.05) and was significantly higher in group D than in group B (P<0.01) or C (P<0.05).α7 nAchR expression was significantly higher in groups C and D than in group B (bothP<0.01). There was a positive correlation between ChAT andα7 nAchR expressions in every group (r=0.444,P=0.007).Conclusions Electroacupuncture at both points Xiaohai and Xiajuxu can reduce the duodenal ulcer score and serum TNF-α expression and increase serum ChAT and duodenalα7 nAchR expressions in DU rats. The results show that the therapeutic effect of electroacupuncture on duodenal ulcer may be produced by regulating TNF-α. Its mechanism may be activating cholinergic anti-inflammatory pathway to produce an anti-inflammatory effect. The effect being better in group D than in group C suggests that Xiajuxu has the relative specificity.
We previously showed that a yin meridian of the upper limb decreased electromyographic activity (root mean square) and muscle strength ipsilateral and contralateral to the side of stimulation. Here, we tested the upper trapezius (UT) muscle response after stimulation of a yang meridian of the upper limb, the small intestine (SI). Thirty-eight healthy volunteers were randomized into the following groups: UT muscle (SI14), distant of the UT muscle (SI8), without stimulation (CG), and sham (R3). An acupuncturist certificated by the Brazilian Society of Physical Therapists and Acupuncturists performed the needle insertion. Each volunteer received only one stimulation to the right upper limb. The evaluation occurred before, 5 minutes after, and 20 minutes after needle withdrawal. The root mean square activity increased on the right side in the UT muscle for the SI8 and SI14 groups (F3,37 = 4.67; p < 0.025) at the 20-minute evaluation. The most vigorous response occurred on the contralateral side because the effects were maintained for 5 minutes after withdrawal (F3,37 = 4.52; p < 0.025). Both groups showed an increase in the UT muscle strength at the 20-minute evaluation (F3,37 = 3.41; p < 0.025). The CG and R3 groups did not show any changes. Our data indicate that SI a yang meridian increases the UT muscle response.
