Traditional Chinese medicine (TCM) retention enema therapy, leveraging localized anti-inflammatory and mucosal regenerative properties, offers a promising alternative. This trial aims to evaluate the efficacy and safety of changrui enema powder (CEP), aiming to establish an evidence-based protocol for managing chronic RRI. Patients and Methods: This multicenter, randomized, triple-blinded controlled trial will enroll 180 participants (2:1 allocation) with grade 2 chronic RRI following pelvic radiotherapy. The experimental group will receive daily CEP enemas for 4 weeks plus a concurrent 1-week course of dexamethasone sodium phosphate (DEX) injection enemas, while the control group will receive an identical-appearing placebo enema for 4 weeks plus a concurrent 1-week course of DEX injection enema. Both interventions will be administered in a total enema volume of 100 mL. The primary outcome is the overall effective rate at 4 weeks, assessed using the LENT-SOMA scoring system. Secondary outcomes encompass TCM syndrome efficacy, the Vienna Rectoscopy Score, pain assessment, and quality of life. Conclusion: This trial is the first study to evaluate the efficacy and safety of a standardized TCM retention enema formulation (CEP) as an add-on to a short-course standard corticosteroid regimen for chronic RRI. The findings are expected to provide an objective clinical basis for integrating TCM into the management of chronic RRI and may inform the development of relevant clinical guidelines. </p>.</p>","PeriodicalId":10541,"journal":{"name":"Complementary Medicine Research","volume":" ","pages":"139-148"},"PeriodicalIF":0.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13021226/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146131493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other realms of modern civilisation, such as science, art, education, politics, philosophy, and religion, to a large extent also suffer from a lack of, or are oblivious to, hómoion-thinking and iásthai-thinking.

Time-domain heart rate variability (HRV) indices, specifically standard deviation of normal-to-normal intervals (SDNN) and root mean square of successive differences (RMSSD), serve as valuable markers of autonomic function. This meta-analysis quantified the effects of TCQ on these HRV parameters and examined whether baseline autonomic function and intervention complexity influenced outcomes.</p><p><strong>Methods: </strong>Following PRISMA 2020 guidelines and a registered protocol (PROSPERO CRD420251053398), randomized controlled and quasi-experimental studies comparing TCQ with control interventions in adults were systematically synthesized. Comprehensive searches were conducted in PubMed, Scopus, CINAHL Ultimate, and MEDLINE Ultimate databases from 2022 to 2025, with earlier studies identified through backward citation tracking. Eligible studies reported time-domain HRV outcomes with SDNN and RMSSD as the primary endpoints. The risk of bias was assessed using RoB 2 for randomized controlled trials and ROBINS-I for non-randomized studies. Random-effects meta-analyses were conducted to estimate Hedges' g with 95% confidence intervals.
