December 15, 2025 updated by: The Fourth Affiliated Hospital of Zhejiang University School of Medicine

Non-targeted Metabonomics Combined With 16S Sequencing to Analyze the Mechanism of Umbilical Moxibustion in the Treatment of IBS-B

Evaluate the therapeutic efficacy of umbilical moxibustion therapy for IBS. Compare and analyze the differences in gut microbiota composition and diversity between the umbilical moxibustion group and the control group based on 16S sequencing.

Compare and analyze the metabolomic differences between the umbilical moxibustion group and the control group based on non-targeted metabolomics, and identify differential metabolites associated with umbilical moxibustion treatment for IBS.

Elucidate the role of the "gut microbiota-metabolite" interaction in the mechanism of umbilical moxibustion for treating IBS.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized primarily by abdominal pain and altered bowel habits. The global prevalence of IBS is approximately 11.2%, while its incidence in China ranges from 2.3% to 15.8%, with IBS-D (diarrhea-predominant IBS) being the most common subtype. This condition is characterized by recurrent episodes and is often difficult to cure. Currently, the pathogenesis of IBS remains unclear. However, as research on gut microbiota advances, increasing evidence suggests that gut microbiota plays a significant role in the development, progression, and treatment of IBS. It can contribute to the occurrence of IBS by damaging the intestinal barrier, activating immune responses, and increasing visceral sensitivity, among other mechanisms. Clinically, umbilical moxibustion therapy, which involves stimulating the Shenque point, has shown good efficacy in treating IBS, though its underlying mechanisms remain unclear. Based on non-targeted metabolomics combined with 16S rRNA gene sequencing technology, this study aims to identify biomarkers and related metabolic pathways associated with umbilical moxibustion in the treatment of IBS. The goal is to preliminarily elucidate the molecular-level mechanisms underlying the therapeutic effects of umbilical moxibustion for IBS.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Sampling Method

Non-Probability Sample

Study Population

Sample Size: 60 cases (30 in the umbilical moxibustion group, 30 in the control group), determined using G*Power (effect size d = 0.8, α = 0.05, β = 0.2; with a minimum of 26 cases per group, 15% attrition rate reserved, final 30 cases per group).

Grouping Method: A random number table generated by SPSS 26.0 was used to allocate participants in a 1:1 ratio, with sealed envelopes employed to conceal group assignments.

Description

Study Type: Prospective, single-blinded, randomized controlled trial (patient-blinded, researcher-unblinded).

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Obtain the original mass spectrometry data
Time Frame: 12 months
Obtain the original mass spectrometry data from metabolomics analysis, screen for differentially expressed small-molecule metabolites (meeting criteria: VIP > 1, adjusted P-value < 0.05, and fold change > 1.5), and identify no fewer than 5 potential biomarkers associated with umbilical moxibustion in the treatment of IBS-D

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 20, 2025

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
