Objective:To investigate the effects of Atractylodes macrocephala decoction pieces on enteric neurotransmitter and stem cell factor(SCF)/stem cell growth factor receptor(c-kit) signaling pathway of interstitial cells of Cajal(ICC) in mice with slow transit constipation(STC). Methods:The STC mouse model was replicated by subcutaneous injection of 2.5 mg/(kg·d) morphine hydrochloride injection. A total of 48 Kunming mice were randomly divided into normal group,model group,Atractylodes macrocephala decoction pieces low,medium,high-dose groups(25,50,100 mg/kg) and mosapride group(1.5 mg/kg),each with 8 mice. After each group was treated with different drugs for 1 week,the stool characteristics and intestinal propulsion rate of mice in each group were tested after modeling and administration. Enzyme-linked immunosorbent assay(ELISA) was conducted to determine neurotransmitter substance P(SP),acetylcholine(Ach),vasoactive intestinal peptide(VIP),nitric oxide(NO) and 5-hydroxytrytamine(5-HT) contents in the colon of the mice in each group. And Western blot was used to detect the expression of SCF and c-kit protein in mouse colon tissue. Results:ELISA results showed that compared with the normal group,the SP and Ach contents of the model group were significantly reduced(SP:230.41±16.41 vs. 146.69±15.59;Ach:577.68±39.35 vs. 281.50±39.40). Compared with the model group,the SP content in the low-dose group of Atractylodes macrocephala,the middle-dose group and the high-dose group of Atractylodes macro-cephala fragments were significantly increased(146.69±15.59 vs. 188.25±4.60;146.69±15.59 vs. 201.78±4.44;146.69±15.59 vs. 307.51±16.94);Ach content in high-dose Atractylodes macrocephala and mosapride group were significantly increased(281.50±39.40 vs. 400.93±12.21;281.50±39.40 vs. 422.22±22.70 ). Compared with the high-dose group of Atractylodes macrocephala decoction pieces,the SP and Ach contents of the low-dose group of Atractylodes macrocephalus decoction pieces and the middle-dose group of Atractylodes macrocephalus decoction pieces were significantly reduced(SP:307.51±16.94 vs. 188.25±4.60;307.51±16.94 vs. 201.78±4.44;Ach:400.93±12.21 vs. 283.79±11.53;400.93±12.21 vs. 327.81±14.77);SP content in the mosapride group was significantly reduced(307.51±16.94 vs. 164.08±12.54). Compared with the normal group,the contents of VIP,NO and 5-HT in the model group were significantly increased(VIP:64.47±2.69 vs. 87.74±2.93;NO:38.21±1.76 vs. 42.78±1.69;5-HT:219.58±11.60 vs. 276.08±7.97). Compared with the model group,the VIP content of the low-dose Atractylodes macrocephala decoction pieces,the medium-dose Atractylodes macrocephalus decoction pieces,the high-dose Atractylodes macrocephalus decoction pieces,and the mosapride group were significantly reduced(87.74±2.93 vs. 75.58±2.08;87.74±2.93 vs. 69.34±2.23;87.74±2.93 vs. 66.37±1.93;87.74±2.93 vs. 65.31±3.32);Atractylodes macrocephala medium dose group,Atractylodes macrocephala fragment high dose group and mosapride group NO and The content of 5-HT was significantly reduced(NO:42.78±1.69 vs. 39.27±1.90;42.78±1.69 vs. 37.43±1.30;42.78±1.69 vs. 35.65±2.01;5-HT:276.08±7.97 vs. 257.89±6.16;276.08±7.97 vs. 226.79±10.49;276.08±7.97 vs. 242.05±12.15). Compared with the high-dose Atractylodes macrocephala decoction pieces group,the contents of VIP,NO and 5-HT in the low-dose Atractylodes macrocephalus decoction pieces group were significantly increased(VIP:66.37±1.93 vs. 75.58±2.08;NO:37.43±1.30 vs. 42.73±2.19;5-HT:226.79±10.49 vs. 269.87±10.91);VIP,5-HT in the middle-dose group of Atractylodes macrocephala and 5-HT in the mosapride group were significantly increased. Western blot results showed that compared with the model group,the c-kit protein content in the low-dose group of Atractylodes macrocephala was significantly increased(0.22±0.10 vs. 0.37±0.08);the middle-dose group of Atractylodes macrocephala and the high-dose group of Atractylodes macrocephala both the SCF and c-kit protein content in the mosapride group and the mosapride group were significantly increased(SCF:0.60±0.19 vs. 0.99±0.28;0.60±0.19 vs. 1.17±0.34;0.60±0.19 vs. 1.02±0.30;c-kit:0.22±0.10 vs. 0.47±0.10;0.22±0.10 vs. 0.58±0.13;0.22±0.10 vs. 0.49±0.13). Conclusion:Atractylodes macrocephala decoction pieces can increase the contents of SP,Ach and SCF/c-kit in the colon tissue of STC model mice,and reduce the contents of VIP,NO and 5-HT,thereby regulating the gastrointestinal function of mice,promoting the intestinal tract peristalsis,improving constipation symptoms,and then achieving the effect of treating STC.
