Objective
To observe the effect of electroacupuncture (EA) at Zusanli (ST 36) on the gastrointestinal motility and the ultrastructures of pacemaker cells [the interstitial cells of Cajal (ICC)] in diabetic gastroparesis (DGP) rats and explore the mechanism of EA for DGP.Methods
A total of 50 Sprague-Dawley (SD) rats were randomly divided into group A, group B, group C, group D and group E, with 10 rats in each group. Group A was the blank control; a single intraperitoneal injection of 2% streptozotocin (STZ) was performed in rats of group B, group C, group D and group E, with high glucose and high fat diet for 8 weeks to establish the DGP rat models. Group B was the model group and the rats did not receive any treatment; group C was EA at acupoint group and the rats received EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6); group D was EA at non-acupoint group and the rats received EA at the control points of Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6); group E was metoclopramide group and the rats were treated by intragastric administration of metoclopramide. Blood glucose was detected using ONE TOUCH blood glucose meter; gastric emptying rate and small intestine migration rate were measured using intragastric phenol red; ultrastructures of gastric antrum ICC were detected by transmission electron microscopy.Results
The differences of blood glucose between group B, group C, group D, group E versus that of group A were statistically significant after modeling (P<0.01); after treatment, the differences of blood glucose between group D, group E versus that of group C were statistically significant (P<0.05, P<0.01); the gastric emptying rate of rats in group B was statistically significant different from that in group A (P<0.01); the gastric emptying rate of rats in group C was statistically significant different from that in group B (P<0.01). The migration rates of rats’ small intestines in group B, group C, group D and group E were all statistically significant different from that in group A (P<0.01); the migration rate of rats’ small intestines in group C was statistically significant different from that in group B (P<0.01). The ultrastructure of rat’s ICC in group B showed apoptosis compared with that in group A; rat‘s ICC in group C had complete basement membrane, more cytoplasm mitochondria, Golgi and rough endoplasmic reticulum, showing clear structure, occasional mitochondria swelling and gap junctions with adjacent smooth muscle cells; there were no significant differences between group D, group E versus group B.Conclusion
EA at Zusanli (ST 36) plus other acupoints can regulate the blood glucose and promote gastrointestinal motility in DGP rats, and the mechanism may be related to repairing the damaged ICC structure.12.
Objective
To observe the effect of point-moxibustion on gastrointestinal motility, mRNA and protein expressions of ghrelin and growth hormone secretagogue receptor 1a (GHSR-1a) in lateral septal nucleus of rats with diabetic gastroparesis (DGP), and to investigate the central regulatory mechanism of DGP treatment with point-moxibustion.Methods
Forty SPF-grade Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, an electroacupuncture (EA) group and a point-moxibustion group, with 10 rats in each group. A DGP rat model was established by intraperitoneal injection of 2% streptozotocin (STZ) with 8-week irregular high-sugar and high-fat diet in the model group, the EA group and the point-moxibustion group; and rats in the blank group were injected intraperitoneally with 0.1 mmoL/L (pH 4.5) citric acid-sodium citrate buffer with 8-week normal diet. Eight weeks later, rats in the EA group were treated by EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6); while rats in the point-moxibustion group were treated by point-moxibustion at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) for successive 15 d. Rats in the blank group and the model group were fixed as the control without intervention. After treatment, intestinal propulsion rate and gastric emptying rate were measured. The mRNA and protein expressions of ghrelin and GHSR-1a in the lateral septal nucleus were detected by real-time polymerase chain reaction (RT-PCR) and Western blot (WB).Results
Compared with the blank group, the intestinal propulsion rate and gastric emptying rate of the model group were significantly lower (both P<0.01); compared with the model group, the intestinal propulsion rate and gastric emptying rate of the EA group and the point-moxibustion group increased significantly (all P<0.05). The mRNA and protein expressions of ghrelin and GHSR-1a were lower in the model group than those in the blank group (all P<0.01). The mRNA and protein expressions of ghrelin and GHSR-1a were significantly higher in the EA group and the point-moxibustion group than those in the model group (all P<0.05). There were no statistically significant differences between the EA group and the point-moxibustion group (all P>0.05).Conclusion
Point-moxibustion at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) can increase the intestinal propulsion rate and gastric emptying rate of DGP rats, and promote the mRNA and protein expressions of ghrelin and GHSR-1a in the central nervous system. The mechanism may be related to the activation of ghrelin pathway in hypothalamic arcuate nucleus-lateral septal nucleus.13.

Objective
To observe the effect of acupuncture at points selected from different regions on the positive expression of interstitial cells of Cajal (ICC) and the stem cell factor (SCF) in gastric antrum tissues in diabetic gastroparesis (DGP) rats, and to explore the influence of region-based point selection on the acupoint combination efficacy.Methods
Sixty Sprague-Dawley (SD) rats were randomly divided into a normal group (group A), a model group (group B), a group of Zusanli (ST 36) plus Zhongwan (CV 12) (group C), a group of Zusanli (ST 36) plus Neiguan (PC 6) (group D), and a group of Zusanli (ST 36) plus non-meridian non-acupoint points (group E), based on the random number table (n=12). DGP rat model was established by single intraperitoneal injection of 2% streptozotocin and common diet. After successful modeling, the rats were treated once a day for 4 weeks. Positive ICC and SCF expressions were measured by immunohistochemistry.Results
Compared with group A, the gastrointestinal propulsion rate of group B showed a statistically significant decrease (P<0.05). Compared with group B, the gastrointestinal propulsion rate and the expression of ICC in the gastric antrum were significantly higher in group C, group D and group E, and the between-group differences were statistically significant (P<0.05); the expression of C-kit protein in group C was statistically significantly higher than that in group D and group E (P<0.05). The expression of SCF protein was significantly increased in group C than in group B, and the difference was statistically significant (P<0.05).Conclusion
Acupuncture can improve the symptoms of delayed gastric emptying in DGP model rats, and regulate the expression of ICC and SCF in gastric antrum tissues. The effect of Zusanli (ST 36) plus Zhongwan (CV 12) in the gastric region is superior to that of the Zusanli (ST 36) plus distal Neiguan (PC 6) or non-meridian non-acupoint point, indicating that region-based point selection is the key factor affecting the effect of acupoint combination.16.
