Effects of Huoxue Tongjiang Decoction (活血通降方) on Esophageal Motility, Serum Inflammatory Factors and Lower Esophageal Sphincter SCF/c-kit Signaling Pathway Reflux Esophagitis Model Rats
将60只大鼠随机分为空白组、模型组及活血通降方低、高剂量组,每组15只。除空白组外,其余各组均采用改良部分贲门肌切开术+外置幽门部分结扎术制备反流性食管炎模型大鼠。造模成功后当天开始给药,活血通降方低、高剂量组给药量分别为3.68、7.35 g /(kg·d),空白组和模型组给予生理盐水5 ml灌胃,均连续14天。检测食管下括约肌平均肌张力变化率和平均振幅变化率、胃重量及胃排空率。HE染色观察大鼠食管组织病理形态学变化,并进行食管黏膜病理评分;测定血清中炎症因子白细胞介素8(IL-8)和肿瘤坏死因子α(TNF-α)浓度;免疫荧光法测定 Cajal间质细胞(ICCs)数量;免疫印记法检测食管下括约肌中酪氨酸激酶受体(c-kit)、干细胞因子(SCF)、亮氨酸拉链和不育-α基序激酶(ZAK)和磷酸化细胞外信号调节激酶(p-ERK)表达。
(活血通降方, HTD) in the treatment of reflux esophagitis (RE).
Methods
2
Sixty rats were randomly divided into blank group, model group, low dose HTD group (L-HTD) and high dose HTD group (H-HTD) group, with 15 rats in each group. Except for the blank group, the rats were given modified partial cardia myotomy and external partial partial pylorus ligation to develop the model of RE. HTD with a dose of 3.68 g /(kg·d) and 7.35 g /(kg·d) were administered in the L-HTD and H-HTD group, respectively, while 5 ml normal saline was given by gavage to both the blank group and the model group since the day when the model was successfully developed. All the administrations lasted for 14 consecutive days. The change rate of the average muscle tone and the average amplitudes of lower esophageal sphincter (LES), the stomach weight and the gastric emptying rate were measured. HE staining was used to observe the histopathological changes of the esophagus tissue, and the pathological score of esophageal mucosa was evaluated. The concentrations of the inflammatory factor interleukin 8 (IL-8) and tumor necrosis factor α (TNF-α) in serum were measured. The number of interstitial cells of Cajal (ICCs) was detected by immunofluorescence, and the expressions of tyrosine kinase receptor (c-kit), stem cell factor (SCF), leucine zipper and sterile alpha motif containing kinase (ZAK) and phosphorylated extracellular signal regulated kinase (p-ERK) in the LES were detected by western blotting.
Results
2
Compared to those in the control group, the change rates of the average muscle tone and the average amplitudes of LES, the gastric emptying rate, the number of ICCs-positive cells, and the expression of c-kit and SCF in the model group decreased, while the stomach weight, the pathological score of the esophageal mucosa, the concentration of IL-8 and TNF-α, and the expressions of ZAK and p-ERK increased (
P
<0.05 or
P
<0.01) in the model group. Compared to those in the model group, the change rates of the average muscle tone and the average amplitudes of LES in the H-HTD group increased (
P
<0.01); the gastric emptying rate, the number of ICCs-positive cells, the expressions of c-kit and SCF in the L-HTD group and the H-HTD group increased, while the stomach weight, the pathological score, the concentration of IL-8 and TNF-α, and the expressions of ZAK and p-ERK decreased (
P
<0.05 or
P
<0.01). The change rates of the average muscle tone and the average amplitudes of LES, and the number of ICCs-positive cells were significantly higher in the H-HTD group than in the L-HTD group (
P
<0.05 or
P
<0.01).
Conclusion
2
HTD can be used to reduce the ZAK expression in the LES and inhibit the p-ERK expression in the treatment of the RE, either by activating the SCF/c-kit signaling pathway and promoting esophageal and gastric motility, or by reducing the concentration of IL-8 and TNF-α in serum and improving the mucosal inflammation of LES; and the higher dose of HTD has better effect.
