Key Finding
This is the first planned network meta-analysis to systematically compare various acupuncture modalities in IBS-D animal models to identify the most effective approaches and clarify their underlying mechanisms.
Researchers are planning a comprehensive review to understand how different types of acupuncture might help people with irritable bowel syndrome with diarrhea (IBS-D). IBS-D causes frequent loose stools and abdominal pain, and its causes are complex, involving inflammation in the gut, problems with the brain-gut connection, and increased sensitivity in the digestive system. While acupuncture shows promise for relieving IBS-D symptoms, scientists haven't yet systematically compared which acupuncture approaches work best or fully understood how they work. This study is actually a protocol—meaning it describes a plan for future research rather than presenting completed results. The researchers will search eight major medical databases for animal studies that tested acupuncture for IBS-D. They'll analyze how different acupuncture methods compare in reducing pain sensitivity, decreasing loose stools, and affecting important biological markers like inflammation-related proteins and gut hormones. By combining data from multiple studies using advanced statistical methods called network meta-analysis, they aim to identify which acupuncture techniques are most effective and understand the biological mechanisms behind their benefits. This research is important because it will help guide future human clinical trials by identifying the most promising acupuncture approaches to test in people with IBS-D. The findings could eventually help practitioners choose the best acupuncture strategies for their patients. If you're considering acupuncture for digestive issues, consult with a licensed acupuncturist who has experience treating gastrointestinal conditions.
This protocol outlines a systematic review and network meta-analysis examining comparative effectiveness of acupuncture modalities in IBS-D animal models. Researchers will conduct a comprehensive search across eight databases (CNKI, WanFang, VIP, CBM, PubMed, Embase, Web of Science, CENTRAL) for randomized controlled animal studies. Primary outcome will be minimal volume threshold for abdominal withdrawal reflex (AWR); secondary outcomes include loose stool rate and biomarkers (IL-1β, TNF-α, SP, 5-HT). Analysis will employ frequentist network meta-analysis using R 4.4.1 and Stata 17.0, calculating standardized mean differences with 95% CI. Treatment rankings will utilize P-scores. Risk of bias will be assessed via SYRCLE tool. This represents the first network meta-analysis integrating direct and indirect evidence from various acupuncture therapies in IBS-D animal models. Clinical implications: Findings will inform optimal acupuncture strategy selection and elucidate mechanisms involving intestinal inflammation, brain-gut axis modulation, and visceral sensitivity, guiding future clinical trial design and translational research.
