Background: Patients with trigeminal neuralgia (TN) often develop a terrible fear of triggering pain, which may lead to anxiety and depression, exerting a negative effect on their quality of life. This protocol is carried out to comprehensively explore the effectiveness and safety of acupuncture for treating anxiety and depression induced by TN. Methods: Randomized control trials involving acupuncture for treating patients with anxiety and depression caused by TN will be searched in eight electric databases, including PubMed, Web of Science, EMBASE, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wanfang Database and Technology Periodical Database (VIP). In addition, studies that were reported in Chinese or English will be considered. Studies selection, data extraction and risk of bias assessment of the included studies will be conducted independently by two reviewers. Quality of the included studies will be performed according to the Cochrane Risk of Bias tool. Meanwhile, the level of evidence for results will be assessed by using the Grading of Recommendations Assessment, Development, and Evaluation method. The primary outcomes will be the Hamilton Anxiety/Depression Scale or Zung Self-Rating Anxiety/Depression Scale, secondary outcomes will be the visual analog score, numerical rating score, SF-36, and adverse events. All analyses will be conducted by using the RevMan software V5.3. Results: A high-quality synthesis of current evidence of acupuncture for TN patients associated with anxiety and depression will be provided in this study. Conclusion: This systematic review will offer comprehensive evidence of acupuncture on specific outcomes induced by TN and TN-related anxiety and depression. Trial registration: PROSPERO registration number: CRD42020219775.
Colon cancer (CC) is a malignancy of the digestive tract, and computed tomography (CT)-guided radiofrequency ablation (RFA) has been extensively adopted in cancer treatment. We aimed to explore the changes in fecal metabolism after CT-guided RFA in CC mice. The orthotopic CC mice received CT-guided RFA upon modeling. Subsequently, we quantified tumor volumes and weights to assess treatment efficacy. Next, because metabolomics is useful for evaluating therapeutic validity, feces were collected for metabolomics analysis. CT-guided RFA inhibited tumor growth effectively. Additionally, metabolomics results showed that the contents of bile acids and fatty acids were downregulated in CC mouse feces. Moreover, the levels of amino acids and carbohydrates were decreased while the levels of fatty acids, organic acids, phenols, pyridines and short-chain fatty acids were elevated in feces after CC mice received CT-guided RFA. Pathway enrichment analysis revealed that those differential metabolites were closely related to fatty acids degradation and synthesis.CT-guided RFA possesses a strong ability to suppress CC development in mice, accompanied by a significant increase of fatty acid content in feces. This study proposes a novel approach and target for CC treatment, which provides hope for CC patients and establishes a solid basis for future in-depth studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
