研究目的: |
本研究将同步采集白癜风患者及健康对照组的唾液及粪便,进行菌群的宏基因测序,旨在比较两组之间的菌群多样性和组成差异。通过分析不同菌群的丰度和多样性,我们将能够识别出与白癜风相关的特定菌群,为理解其发病机制提供重要线索。通过检测白癜风患者及健康对照者粪便中的短链脂肪酸(SCFAs)水平,系统评估其在疾病发生发展过程中的变化趋势。结合微生态数据,探讨短链脂肪酸与肠道菌群结构、功能的相关性,进一步分析其与白癜风临床表型及免疫状态的关系。通过明确短链脂肪酸在白癜风中的作用,为揭示肠道代谢产物参与疾病调控提供科学依据。 |

Objectives of Study: |
This study will simultaneously collect saliva and feces from patients with vitiligo and healthy control subjects for microbiome metagenomic sequencing, aiming to compare the diversity and composition differences of the microbiota between the two groups. By analyzing the abundance and diversity of different microbial communities, we will be able to identify specific microbiota associated with vitiligo, providing important clues for understanding its pathogenesis. By measuring short-chain fatty acid (SCFA) levels in the feces of vitiligo patients and healthy controls, we will systematically evaluate their changes during the disease's development. Combined with microecological data, we will explore the correlation between SCFAs and gut microbiota structure and function, and further analyze their relationship with the clinical phenotype and immune status of vitiligo. By clarifying the role of SCFAs in vitiligo, we aim to provide scientific evidence for elucidating how gut metabolic products are involved in disease regulation. |
