Clinical Trial Summary

Multidisciplinary techniques such as multimodal neuroimaging, microbiology, and bioinformatics were applied to study the differences in correlation characteristics between gut microbes, functional brain networks, and peripheral inflammation among patients with active Crohn's disease (CD), CD in remission, and healthy subjects.

Intervention

Other:
• Acupuncture treatment
We selected acupoints including Zhongwan (CV12) and bilateral Shangjuxu (ST37), Sanyinjiao (SP6), Gongsun (SP4), Taichong (LR3), Taixi (KI3), Hegu (LI4), and Quchi (LI11)17 according to the World Health Organization standard. Single-use 0.30×40 mm or 0.30×25 mm acupuncture needles (Hwato, Suzhou, China) 27,28 were vertically inserted into each acupoint to 20-30 mm depth to obtain a deqi sensation (a soreness, distention, numbness or heaviness sensation). Bilateral Zusanli (ST36) and Tianshu (ST25) were selected for moxibustion. Pure moxa sticks (diameter: 2.8 cm; Hanyi, Nanyang, China) were ignited and fixed on a moxibustion stand at a distance of 3-5 cm to the surface of acupoints. The temperature of skin surface at the acupoints was maintained at 43 ± 1°C and monitored with a miniature infrared thermometer (Fluke 62, Fluke Corporation, Everett, WA, USA). Acupuncture and moxibustion were concomitantly performed for 30 min.
• Sham acupuncture
Sham acupuncture needles (0.35×40 mm) with flat tips (Hwato, Suzhou, China) were inserted towards the same acupoints to induce slight pain but without penetrating the skin. Sham moxibustion was made by igniting the same type of moxa sticks but fixing them at a distance of 8-10 cm from the skin of acupoints to maintain the temperature at 37 ± 1°C. Sham acupuncture and moxibustion were concomitantly performed for 30 min.
