Abstract
AIM
To analyze the therapeutic effect of Huangqi Jianzhong decoction on diabetic gastroparesis (DGP) in rats and its impact on the stem cell factor (SCF)-Kit signaling pathway in the gastric antrum.
METHODS
Seventy-five male Wistar rats of SPF grade were randomly divided into five groups: model group, normal group, positive control group, low-dose Huangqi Jianzhong decoction group, and high-dose Huangqi Jianzhong decoction group (15 rats in each group). Except the normal group, DGP was induced in other groups. After DGP was induced, the rats in the positive control group were intra-gastrically administered with 0.78 g/mL of morphine suspension, and the two Huangqi Jianzhong decoction groups were intra-gastrically administered with 0.78 g/mL and 3.12 g/mL of Huangqi Jianzhong decoction. The normal group and the model group were given normal saline. The dose of each group was 10 mL/kg. After continuous administration for 6 wk, the general condition, body weight, gastric emptying rate, serum soluble SCF (sSCF), gastrin (GAS), motilin (MLT), and interstitial cells of Cajal (ICC) in the gastric antrum were observed. C-kit and membrane-bound SCF (mSCF) protein expression was detected.
RESULTS
Compared with the normal group, the blood glucose, GAS, and MLT levels in the model group increased, and the sSCF content and gastric emptying rate decreased. Compared with the model group, positive control group, and low dose Huangqi Jianzhong decoction group, the contents of blood glucose, GAS, and MLT significantly decreased, and the sSCF content and gastric emptying rate significantly increased in the high-dose group (P < 0.05). Compared with the normal group, the expression of c-kit and mSCF proteins in the gastric antrum decreased in the model group. Compared with the model group, the expression of c-Kit and mSCF proteins in the positive control group, low-dose and high-dose Huangqi Jianzhong decoction groups significantly increased (P < 0.05). Compared with the positive control group, the expression of c-Kit and mSCF proteins in the low-dose and high-dose Huangqi Jianzhong decoction groups increased, but the difference was not statistically significant (P > 0.05).
CONCLUSION
Huangqi Jianzhong decoction enhances the expression of mSCF protein and up-regulates the SCF-Kit signaling pathway, which increases the number of ICC in the gastric antrum of DGP rats, improves gastric pacing function, and enhances gastric motility.
