AIM: To investigate the effect and mechanism of electro-acupuncture lEA) at ST25 and ST37 on irritable bowel syndrome (IBS) of rats. METHODS: A total of 21 male Sprague-Dawley rats were randomly divided into normal group, model group and EA group. A rat model of IBS was established by constraining the limbs and distending the colorectum of rats. Rats in EA group received bilateral EA at ST25 and ST37 with a sparse and intense waveform at a frequency of 2/50 Hz for 15 min, once a day for 7 d as a course. Rats in normal and model groups were stimulated by distending colorectum (CR). An abdominal withdrawal reflex (AWR) scoring system was used to evaluate improvements in visceral hypersensitivity. Toluidine blue-improved method, immunohistochemistry and radioimmunoassay were used to observe mucosal mast cells (MC), changes of substance P (SP) and substance P receptor (SPR) in colon and change of corticotropin-releasing hormone (CRH) in hypothalamus. RESULTS: The threshold of visceral sense was significantly lower in model group than in normal group,and significantly higher in EA group than in model group. The number of mucosal MC was greater in model group than in normal group and significantly smaller in EA group than in model group. The CRH level in hypothalamus of rats was significantly higher in model group than in normal group, which was remarkably decreased after electro-acupuncture treatment. The SP and SPR expression in colon of rats in model group was decreased after electro-acupuncture treatment. CONCLUSION: EA at ST25 and ST37 can decrease the number of mucosal MC and down-regulate the expression of CRH in hypothalamus, and the expression of SP and SPR in colon of rats with IBS. 展开更多

AIM: To investigate the effects of moxibustion on down-regulation of the colonic epithelial cell apoptosis and repair of the tight junctions in rats with Crohn's disease (CD). METHODS: Sixty male Sprague-Dawley rats were randomly divided into a normal control (NC) group, a model control (MC) group, an herbs-partitioned moxibustion (HPM) group, a mild-warm moxibustion (MWM) group and a salicylazosulphapyridine (SASP) group, with 12 rats in each group. The CD model rats were treated with trinitrobenzene sulphonic acid to induce intestinal inflammation. The rats in the HPM and MWM groups were treated at the Tianshu (ST25) and Qihai (CV6) acupoints once daily for 14 d, and the SASP group was fed SASP twice daily for 14 d. No additional treatment was given to the MC and NC groups. Themicrostructure of the colonic epithelium was observed under a transmission electron microscope, the transepithelial resistance was measured using a shortcircuit current, colonic epithelial cell apoptosis was determined by terminal deoxynucleotidyl transferasemediated dUTP-biotin nick end labelling assay, and the expression of occludin, claudin-1 and zonula occludens-l (ZO-1) in the colonic epithelial junction was determined by Western blotting and immunofluorescence staining. RESULTS: Compared with the MC group, the microstructure of the colonic epithelial barrier was signifi-cantly improved in rats treated with HPM, MWM or SASP, meanwhile, the current flow was reduced signifi-cantly, with values of 168.20 ± 6.14 vs 99.70 ± 3.13, 99.10 ± 4.28 and 120.30 ± 3.65 mA, respectively (P = 0.001). However, the HPM and MWM groups had higher current flow rates than the SASP group (99.70 ± 3.13, 99.10 ± 4.28 vs 120.30 ± 3.65 mA, P = 0.001). The number of the apoptotic colonic epithelial cells in HPM, MWM and SASP groups was largely reduced (61.5 ± 16.91 vs 15.5 ± 8.89, 14.8 ± 6.27 and 24.7 ± 9.68, respectively (P = 0.001); and the expression of occlu- din, claudin-1 and ZO-1 in the MWM and HPM groups was signifi cantly enhanced (0.48 ± 0.10, 0.64 ± 0.09 vs 0.18 ± 0.05 for occludin, 0.12 ± 0.02, 0.17 ± 0.03 vs 0.05 ± 0.01 for claudin-1, and 0.08 ± 0.01, 0.11 ± 0.01 vs 0.02 ± 0.01 for ZO-1). And in SASP group, the expression of occludin and ZO-1 was also signifi cantly increased (0.27 ± 0.04 vs 0.18 ± 0.05 for occludin and 0.05 ± 0.01 vs 0.02 ± 0.01 for ZO-1), but there was no significant difference for claudin-1. The HPM and MWM groups had higher expression of occludin, claudin-1 and ZO-1 than the SASP group. CONCLUSION: HPM and MWM treatment can down-regulate apoptosis of colonic epithelial cells, repair tight junctions and enhance colonic epithelial barrier function in rats with CD. 展开更多

AIM To investigate the effect and mechanism of moxibustion in rats with ulcerative colitis.METHODS A rat colitis model was established by administering 4% dextran sulphate sodium solution. Seventy male rats were randomly divided into seven groups: Healthy controls(HC), ulcerative colitis model group(UC), UC with 7 d of moxibustion(UC-7), UC with 14 d of moxibustion(UC-14), UC with mesalazine gavage(UC-W), HC with 7 d of moxibustion(HC-7), HC with 14 d of moxibustion(HC-14). Moxibustion was applied to the bilateral Tianshu(ST25). Gut microbiome profiling was conducted by 16 S r RNA amplicon sequencing, and PCR and ELISA determined the expression of inflammatory cytokines in colon mucosa and serum, respectively. RESULTS Moxibustion treatment restored the colonic mucosa and decreased submucosal inflammatory cell infiltration in colitis rats. Rats treated with moxibustion and mesalazine had significantly lower levels of the dominant phyla Proteobacteria and the genera Saccharibacteria, Sphingomonas and Barnesiella than colitis rats, and they could restore the microbiome to levels similar to those observed in healthy rats. UC rats had reduced alpha diversity, which could be alleviated by moxibustion therapy, and UC-7 had a higher alpha diversity than UC-14. This finding suggests that short-term(7 d) but no longer term(14 d) moxibustion treatment may significantly affect the gut microbiome. The potential bacterial functions affected by moxibustion may be ascorbate and aldarate metabolism, and amino acid metabolism. Compared with HC group, the levels of the cytokines interleukin-12(IL-12)(P < 0.05) and IL-6, IL-17, IL-23, interferon-γ, lipopolysaccharide, Ig A, tumour necrosis factor-α and its receptors 1(TNFR1) and TNFR2(P < 0.01) were all increased, whereas anti-inflammatory cytokine IL-2 and IL-10(P < 0.01) and transforming growth factor-β(P < 0.05) were decreased in UC rats. These changes were reversed by moxibustion.CONCLUSION Our findings suggest that moxibustion exerts its therapeutic effect by repairing mucosal tissue damage and modulating the gut microbiome and intestinal mucosal immunity. 展开更多

AIM To observe whether there are differences in the effects of electro-acupuncture(EA) and moxibustion(Mox) in rats with visceral hypersensitivity. METHODS EA at 1 m A and 3 m A and Mox at 43?℃ and 46?℃ were applied to the Shangjuxu(ST37, bilateral) acupoints in model rats with visceral hypersensitivity. Responses of wide dynamic range neurons in dorsal horns of the spinal cord were observed through the extracellular recordings. Mast cells(MC) activity in the colons of rats were assessed, and 5-hydroxytryptamine(5-HT), 5-hydroxytryptamine 3 receptor(5-HT3R) and 5-HT4Rexpressions in the colons were measured.RESULTS Compared with normal control group, responses of wide dynamic range neurons in the dorsal horn of the spinal cord were increased in the EA at 1 m A and 3 m A groups(1 m A: 0.84 ± 0.74 vs 2.73 ± 0.65, P < 0.001; 3 m A: 1.91 ± 1.48 vs 6.44 ± 1.26, P < 0.001) and Mox at 43?℃ and 46?℃ groups(43?℃: 1.76 ± 0.81 vs 4.14 ± 1.83, P = 0.001; 46?℃: 5.19 ± 2.03 vs 7.91 ± 2.27, P = 0.01). MC degranulation rates and the expression of 5-HT, 5-HT3 R and 5-HT4 R in the colon of Mox 46?℃ group were decreased compared with model group(MC degranulation rates: 0.47 ± 0.56 vs 0.28 ± 0.78, P < 0.001; 5-HT: 1.42 ± 0.65 vs 7.38 ± 1.12, P < 0.001; 5-HT3R: 6.62 ± 0.77 vs 2.86 ± 0.88, P < 0.001; 5-HT4R: 4.62 ± 0.65 vs 2.22 ± 0.97, P < 0.001). CONCLUSION The analgesic effects of Mox at 46?℃ are greater than those of Mox at 43?℃, EA 1 m A and EA 3 m A. 展开更多

BACKGROUND A20 inhibits intestinal epithelial cell apoptosis in Crohn's disease, and herbspartitioned moxibustion(HPM) has been demonstrated to be an effective treatment for Crohn's disease. However, the mechanism by which HPM reduces intestinal epithelial cell apoptosis in Crohn's disease has not been thoroughly elucidated to date.AIM To elucidate whether HPM exerts its effects by upregulating A20 to affect intestinal epithelial cell apoptosis in a Crohn's disease mouse model.METHODS In this study, mice with A20 deletion in intestinal epithelial cells(A20 IEC-KO) were utilized to establish a Crohn's disease mouse model with 2,4,6-trinitrobenzenesulfonic acid(TNBS) administration, as well as wild-type mice. Mice were randomly divided into normal control(NC), model control(MC), mesalazine(MESA), and HPM groups. The morphology of the colonic mucosa was observed by hematoxylin-eosin staining, and serum endotoxin and apoptosis of epithelial cells were evaluated by enzyme-linked immunosorbent assay and terminal dUTP nick-end labeling assay accordingly. The protein expression levels of A20 and tumor necrosis factor receptor 1(TNFR1)-related signaling molecules were evaluated by Western blot, and co-expression of A20 and TNFR1-associated death domain(TRADD) and co-expression of A20 and receptor-interacting protein 1(RIP1) were observed by double immunofluorescence staining.RESULTS The intestinal epithelial barrier was noted to have an improvement in the HPM group of wild-type(WT) mice compared with that in A20 IEC-KO mice. Compared with A20 IEC-KO HPM mice, serum endotoxin levels and apoptosis percentages were decreased(P < 0.01), A20 expression levels were increased(P < 0.01), and expression of TNFR1, TRADDD, and RIP1 was decreased in the HPM group of WT mice(PTNFR1 < 0.05, PTRADD < 0.01, PRIP1 < 0.01). Both of the co-expression of A20/TRADD and A20/RIP1 showed a predominantly yellow fluorescence in the HPM group of WT mice, while a predominantly red fluorescence was noted in the HPM group of A20 IEC-KO mice.CONCLUSION Our findings suggest that HPM in treating Crohn's disease functions possibly via upregulation of the A20 expression level, resulting in downregulation of TNFR1,TRADD, and RIP1 to alleviate increased cell apoptosis in the intestinal epithelial barrier in Crohn's disease. 展开更多

Objective: To compare the effects of electroacupuncture (EA) and mild-warm moxibustion (Mox) therapies for constipation-predominant irritable bowel syndrome (C-IBS) patients. Methods: Sixty C-IBS patients were assigned to 2 groups by simple randomized method, i.e. EA group (30 cases) and Mox group (30 cases). Both EA and Mox treatments were performed on bilateral Tianshu (ST 25) and Shangjuxu (ST 37) for 30 min each time, 6 times per week, for 4 consecutive weeks. The gastrointestinal symptoms and psychological symptoms of the two groups were scored before and after treatment. The effects on the corresponding functional brain areas, namely the anterior cingulate cortex (ACC), insular cortex (IC) and prefrontal cortex (PFC) were observed by functional magnetic resonance imaging (fMRI) before and after treatment. Results: Compared with the Mox group, greater improvements in abdominal distension, defecation frequency, difficulty in defecation and stool features were observed in the EA group (all P〈0.01), both Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale scores were significantly decreased in the EA group (all P〈0.01). Finally, decreased activated voxel values were observed in the ACC, right IC and PFC brain regions of EA group with 150 mL colorectal distension stimulation (P〈0.05 or P〈0.01). Conclusions: Both EA and Mox could significantly improve some of the most intrusive symptoms of C-IBS patients, and EA was more effective than Mox. The therapeutic effect of these two therapies might through modulating of the brain-gut axis function. (Registration No. ChiCTR- TRC-11001349). 展开更多
