Methods: Sixty Sprague-Dawley (SD) rats were randomly divided into a blank control group (group A), a model group (group B), a ranitidine group (group C), and a herbal cake-partitioned moxibustion group (group D) by random digit, 15 rats in each group. Rat models of spleen deficiency syndrome were made by intragastric administration of 4℃ 200% concentrated Da Huang (Radix et Rhizoma Rhei). After successful modeling, the rats in group C were treated with 25 mg/(kg.bw) ranitidine by intragastric adminstration and rats in group D were treated with herbal cake-partitioned moxibustion at Zusanli (ST 36) and Zhongwan (CV 12), for 8 d. Excepted for rats in group A, all the other rats were treated with indomethacin at 5 mg/(kg.bw) at 8:00 a.m. on the second day after finishing all the intervention and sacrificed 7 h later to isolate the stomach. Histopathological changes of the gastric tissues were observed under light microscope after hematoxylin-eosin (HE) staining. The protein expressions of MEK:1/2 and ERK:1/2 in the gastric tissues were detected by immunohistochemistry. Results: After intervention, the gastric mucosal injury in group B was significantly severer than that in group A, with large breakage and ablating; the damage of gastric mucosa was decreased in group C compared with group B; the gastric mucosal surface remained relatively complete, and the status of breakage and ablating was significantly improved. After intervention, compared with group A, the protein expressions of MEK:1/2 and ERK:12 in gastric tissues of the other groups were significantly higher (P〈0.01). Compared with group B, the protein expressions of MEK:1/2 and ERK:1/2 in group C and D were significantly higher (all P〈0.01). Compared with group C, the protein expressions of MEK:1/2 and ERK:1/2 in group D were significantly higher (P〈0.01). Conclusion: Herbal cake-partitioned moxibustion promotes the repair of gastric mucosa in rats with spleen deficiency syndrome, via improving protein expressions of MEK:1/2 and ERK:1/2 in gastric tissues, as well as activating MEK/ERK signaling pathway.展开更多

Methods: Seventy-five SPF grade Sprague-Dawley (SO) rats were randomly divided into a blank control group (group A), a model group (group B), a 3 moxa-cone ginger-partitioned moxibustion group (group C1), a 6 moxa-cone ginger-partitioned moxibustion group (group C2) and a 9 moxa-cone ginger-partitioned moxibustion group (group C3) using random number table method, 15 rats in each group. Except group A, rats in the other groups received intragastric administration of 4 ~C 200% concentrated Da Huang (Radix et RhizomaRhei) to prepare spleen deficiency syndrome model. After successful modeling, rats in group B received no treatment; rats in group C1, C2 and C3 were treated with 3, 6 and 9 moxa-cone ginger-partitioned moxibustion at Zusanli (ST 36)and Zhongwan (CV 12) respectively for 8 continuous days. The general symptom score of rats was observed. The serum levels of TFF1 and MUC5AC were detected by enzyme-linked immunosorbent assay (ELISA). The expression of EGFR protein in gastric mucosa was detected by immunohistochemistry. Results: After the treatment, compared with group A, the spleen deficiency symptom score was increased in group B, the levels of serum TFF1 and MUC5AC, the EGFR protein expression in gastric tissues of group C1, C2 and C3 were significantly increased (all P〈0.01); compared with group B, the spleen deficiency scores were decreased in group C1, C2 and C3, and the serum levels of TFF1 and MUC5AC, as well as EGFR protein expression in gastric tissues were increased (all P〈0.01). Compared with group C1, the spleen deficiency scores were decreased in group C2 and C3, the serum levels of TFF1 and MUC5AC, and the expression of EGFR protein in gastric tissues were increased (all P〈0.01), however, there was no significant difference between group C2 and C3 (all P〉0.05). The mechanism may be related to the increase of serum TFF2 and MUC5AC levels and activation of EGFR protein. Conclusion: Ginger-partitioned moxibustion can improve the symptoms, as well as promote the proliferation and repair of gastric mucosa in rats with spleen deficiency. The therapeutic efficacy of 6 or 9 moxa-cone ginger-partitioned moxibustion is better than that of 3 moxa-cone ginger-partitioned moxibustion, while the efficacies are equivalent between 6 and 9 moxa-cone Ringer-Dartitioned moxibustion groups.展开更多
