The clinical therapeutic effect and mechanism of 134.ck Shu (Pishu, Weishu) were studied since 1978. (1) The total effective rate in 70 cases with stomachache treated by needling Pishu, Weishu was 93.94%. There was significant difference as compared with the control group. (2) Among the 33 cases of subtotal gastrectomy and gastroduodenal ulcer before operation, there was 89.39% tenderness reactive points concentrated on pishu and Weishu and those points between them, rope from reactive mass could be touched in 53.03%. (3) A direct observation of the influence of needling Pishu and Weishu on the peristalsis of the stomach was performed by the application of fiber gastroscope. After needling, the rate of changes of movement of the stomach was 93.33%. There were significant differences as compared with the control group. In our observations, it was indicated that there may be relative regularities and specificities between Shu points and Zang Fu organs and function of the vegetative nervous system.
Stomachache is often encountered clinically and cured effectively by acupuncture treatment. However, there have been few reports on a quantitative analysis of their pain-killing effects. The authors employed a pain scale to score the level of pain quantitatively in patients with stomachache, and compared effects of electroneedling treatment on Weishu (BL 21) and Weishu-like points using such scores, the results show better effects with Weishu-like points. A report follows.
Objective : To observe the therapeutic effect of electroacupuncture (EA) of “Zusanli” (ST 36) and “Weishu” (BL 21 ) on the experimental gastric ulcer in Xu-period of a day for analyzing the best opportunity of acupuncture treatment of gastric ulcer. Methods : 49 Wistar rats were randomly divided into 1 control group, (2) ST-36-Xu group, (1) BL-21 1 -Xu group, (4) ST-36-Chen group, 5 BL-21 1 -Chen group, (P ST-36-IT group, and (7) BL-21 1 -IT group, with 7 rats in each group. Rat gastric ulcer model was established using intra-gastric administration of glacial acetic acid. Gastric mucosal thickness, mucosal muscular defect width, superficial mucosal mucus index (MI) , intramucosal MI , Total Mi, plasma 6-keto-PGF 1 a , serum NO and gastric tissue CGRP concentrations were used as the indexes. The EA treatment was conducted once daily at Xu-period (7 - 9 o'clock in the evening), Chen-period (8 - 10 o'clock in the morning) and irregular time (IT) with 6 days being a therapeutic course, two courses altogether. Results: After EA treatment, 1 the regenerated mucosal thickness values of the aforementioned 6 EA groups. particularly ST-36-Xu group and BL-21-Xu group, were all apparently higher than that of control group (P< 0. 05 - 0. 01), while the mucosal muscle layer defect width values of different EA groups, particularly ST-36-Xu group and BL-21-Xu group, were strikingly lower than that of control group (P < 0. 05 - 0. 01 ); Othe 3 MI of the 6 EA groups, particularly those of ST-36-Xu group were all significantly higher than those of control group (P< 0. 05 - 0. 0 1); (3) plasma 6-keto-PGF1a contents of the 6 EA groups, particularly those of ST-36-Xu and BL-21 I -Xu groups, were all significantly higher than that of control group (P< 0 - 05 - 0. 01); 4 serum NO and gastric tissue CGRP concentrations of the 6 EA groups, particularly those of ST-36-Xu and BL-21-Xu groups and CGRP concentration of ST-36-Chen group, were all significantly higher than those of control group (P<0. 05 - 0. 0 1); and 5 there were positive correlation between superficial Mi or total MI and NO level (r= 0. 858, 0. 987, P< 0. 05,and 0. 01), and between the superficial mucus index and CGRP concentration (r= 0. 9051, t = 4. 68, P < 0. 01 ), suggesting that the increase of the secretion function of the regenerated mucosal mucus is related to acupuncture induced increase of release of both NO and CGRP. Conclusion : The therapeutic effect of EA of ST-36 and BL-21 in Xu-period is better in the treatment of gastric ulcer. and that of EA of ST-36 is the best.

A large number of studies have been conducted to explore the efficacy of electroacupuncture (EA) for the treatment of gastrointestinal motility. While several lines of evidence addressed the basic mechanism of EA on gastrointestinal motility regarding effects of limb and abdomen points, the mechanism for effects of the back points on gastric motility still remains unclear. Here we report that the NMDA receptor (NMDAR) antagonist kynurenic acid inhibited the gastric emptying increase induced by high-intensity EA at BL21 and agonist NMDA enhanced the effect of the same treatment. EA at BL21 enhanced NMDAR, but not AMPA receptor (AMPAR) component of miniature excitatory postsynaptic current (mEPSC) in gastric-projecting neurons of the dorsal motor nucleus of the vagus (DMV). In sum, our data demonstrate an important role of NMDAR-mediated synaptic transmission of gastric-projecting DMV neurons in mediating EA at BL21-induced enhancement of gastric emptying.
A large number of studies have been conducted to explore the mechanism of Back-Shu and Front-Mu points. While several lines of evidence addressed the acupuncture information of Shu acupoints and Mu acupoints gathering in the spinal cord, whether the convergence is extended to the high centre still remains unclear. The study selected gastric Mu points (RN12) and gastric Shu points (BL21) regulating gastric motility and its central neural mechanisms as the breakthrough point, using the technique of immunochemistry, nuclei lesion, electrophysiology, and nerve transection. Here, we report that gastric motility regulation of gastric Shu and Mu acupoints and their synergistic effect and the signals induced by electroacupuncture (EA) stimulation of acupoints RN12 and RN12 gather in the dorsal vagal complex (DVC), increasing the levels of gastrointestinal hormones in the DVC to regulate gastric motility through the vagus. In sum, our data demonstrate an important role of DVC and vagus in the regulation of gastric motility by EA at gastric Shu and Mu points.
The objective of this work is to study the effect of the moxibustion in the acupointsShu-Mo corresponding to Wei (stomach) and to Xiaochang (smallintestine)in gastrointestinal motility Material- 68 female EPM-I/Wistar rats were used, weight ranging from 195 to 230 grams;pasty substance made of powdered coal (28.57%), powdered Arabic gum (28.57%), and filtered water (42.85%), and moxa in stick.Methods - The animals were kept on a 24 hour fast, randomly distributed in 4 groups of 17 female rats each, submitted the administration of 1.5 ml of the pasty substance of coal, with previous superficial anesthesia of sulfuric ether, and submitted to the following procedures. Control Group (1): The female rats were returned to the cage. MOXA GROUP (11): The female rats were kept under anesthesia with sulfuncether, the acupoints B-21 (Weishu), B-27(Xiaochangshu), VC-12 (Zhongwan) and VC-4 (Guanyuan) were located and the moxibustion technique was performed for 5 minutes under narcosis. At the end of moxibustion the female rats were returned to the cage. Sham Group (IlI):non-acupoints were located (bilateral anterior axillary area) and the moxibustion technique was performed for 5 minutes, under narcosis. Ether Group (IV): The female rats were kept under an esthesia with sulfuric ether for 5 minutes. At the end of the scheduled time, they were returned to the cage. All animals in the 4 groups were sacrificed with sulfuric ether in the twentieth minute of the experiment. Surgical removal of the small intestine and clamping of the distal portion reached by the coal were performed, and the progression distance of coal since the pylorus and the total length of the small intestine were measured. Results - Kruskal-WalJis points variance analysis and the multi comparison test showed that groups Control and Moxa did not present much difference, and had an absolute progression of coal that was significantly longer them Sham and Ether groups. As to the length of the small intestine, no significant value among the groups was found. Vanance analysis of Kruskal-WaDispoints showed as regards the percent ratio (coal progression/length of smal intestine), that the Control and Moxa groups did not vary significantly and that they exhibited a significantly higher percent than the values observed in the Sham and Ether Groups.
