[Herbal cake-partitioned moxibustion improves intestinal epithelial barrier dysfunction by suppressing TNF-α-mediated apoptosis pathway of intestinal epithelium in rats with Crohn's disease].

Researchers in China investigated whether herbal cake-partitioned moxibustion could help heal the intestinal damage caused by Crohn's disease, a chronic inflammatory bowel condition. In this traditional therapy, burning moxa cones are placed on herbal cakes positioned over specific acupuncture points. The study used 48 male rats that were divided into four groups: healthy controls, untreated disease models, moxibustion treatment, and standard medication treatment. Researchers created Crohn's disease in the rats and then treated one group with moxibustion at two acupuncture points (Tianshu/ST25 and Qihai/CV6) once daily for 10 days, while another group received standard medication. After treatment, scientists examined the intestinal lining cells to see how well they functioned as a protective barrier. They found that moxibustion significantly reduced intestinal barrier leakage and decreased cell death in the intestinal lining. The treatment appeared to work by blocking a specific inflammatory pathway involving a protein called TNF-alpha, which triggers cell death in Crohn's disease. Both moxibustion and medication showed similar beneficial effects in reducing intestinal permeability and protecting intestinal cells from dying. The researchers concluded that herbal cake-partitioned moxibustion may help repair the damaged intestinal barrier in Crohn's disease by suppressing harmful inflammatory signals. While these animal study results are promising, human clinical trials would be needed to confirm whether this traditional therapy could benefit people with Crohn's disease. If considering moxibustion for digestive conditions, seek treatment from a licensed acupuncturist trained in traditional Chinese medicine techniques.

This rat model study (n=48) examined herbal cake-partitioned moxibustion's effects on intestinal epithelial barrier dysfunction in Crohn's disease through the TNF-α/TNFR1/TRADD/FADD apoptotic pathway. CD was induced via intra-anal TNBS perfusion over 4 weeks. The moxibustion group received treatment at ST25 and CV6 (two cones daily for 10 days) and was compared to mesalazine medication and untreated controls. Post-treatment analysis of cultured intestinal epithelial cells exposed to TNF-α (100 ng/mL) showed moxibustion significantly reduced fluorescence transmittance (barrier permeability), apoptosis rates, and expression of TRADD, RIP1, and FADD proteins (P<0.001-0.01) compared to the model group. Expression of protective A20 protein increased significantly (P<0.01). Effects were comparable to standard medication. Clinical implication: Moxibustion at ST25 and CV6 may protect intestinal epithelial integrity in IBD by modulating TNF-α-mediated apoptosis, suggesting a mechanistic basis for traditional point selection in digestive disorders.
