Brief Summary

Irritable bowel syndrome (IBS) is a common functional disorder of the digestive system characterized by recurrent abdominal pain associated with bowel movements or changes in bowel habits. Although there are reviews and guidelines for treating IBS, the complexity and diversity of IBS manifestations make treatment difficult. By detecting and exploring the biological characteristics presented by the relevant meridian point reaction, this project clarified the specificity and regularity of the connection between the acupoint and the Zangfu reflected by this phenomenon, and conducted correlation analysis based on the intestinal flora, tryptophan metabolite levels and related scales of patients with IBS.

Outcome Measures

Primary Outcomes (5)

  • Pain sensitivity

    Select the measurement point, place the probe of the handheld pain threshold testing instrument vertically on the pain measurement point, slowly and steadily press, and stop the pressure when the subject feels pain (or the subject can stop the pressure). At this point, the reading on the monitor is the subject's pain threshold. After the measurement is completed, press the zero button to measure the next point or the next subject.

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • Thermal radiation characteristics

    The NEC R550 infrared thermal imager and the InfRec Analyzer NS9500 computer software were used to store and save the infrared thermal images taken, and the temperature data were analyzed, the temperature values of relevant acupoints in corresponding coordinates were extracted, and the average temperature values of acupoints in the 6 infrared thermal images were calculated as their basic temperatures.

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • Microcirculation characteristics

    The PeriCam PSI laser speckle imager was adopted to store and record the speckle imaging images and curves with the support of PIM Soft computer software, and the blood flow data was analyzed, the blood flow values of the corresponding acupoints were extracted, and the average perfusion volume of the acupoints within 2 minutes was calculated as the perfusion volume index.

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • Electrical characteristics

    Meridian point resistance meter was used to measure the point resistance, each point was detected for 5 minutes, the data was stored and analyzed by excel2019, the relative resistance value of the corresponding point was extracted, and the average resistance value of the point was calculated within 5 minutes.

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • Biological ultra-weak luminescence

    It is divided into the UPE detection system of photomultiplier tube (PMT) and the UPE image acquisition system of charge coupled device (CCD).PMT: The data of each measurement point is the self-luminous intensity of the subject per second.CCD: The image acquisition software Andor Solis is used to store the captured CCD image, analyze the ultra-weak luminescence data of the acquisition site, and extract the average value of the ultra-weak luminescence of the corresponding position as its basic value.

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

Secondary Outcomes (10)

  • Intestinal flora

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • Tryptophan metabolites

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • Bristol Fecal Traits Grading Scale

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • Severity of IBS (IBS-SSS)

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • IBS Quality of Life (IBS-QOL )

    the baseline and 4 times during the follow-up period (1st month, 2nd month, 4th month and 6th month after enrollment)

  • +5 more secondary outcomes
