研究目的:

验证长双歧杆菌CCFM1195与膳食因子复配配方对MHD患者体内蛋白结合类毒素的清除效能(主要终点)及肠道微生态-宿主互作网络的协同调控作用(次要终点)。通过多维度分析毒素水平、菌群动态、代谢物谱、肠屏障功能及炎症状态的改善效果,揭示膳食干预靶向微生物代谢重塑的分子机制,最终为MHD患者基于肠道菌群的透析补充疗法提供参考。  

Objectives of Study:

To verify the clearance efficacy of protein-bound toxins in MHD patients (the primary endpoint) and the synergistic regulatory effect on the intestinal microbiota-host interaction network (the secondary endpoint) by the combined formula of Bifidobacterium longum CCFM1195 and dietary factors. Through multi-dimensional analysis of the improvement effects on toxin levels, microbiota dynamics, metabolite profiles, intestinal barrier function and inflammatory status, the molecular mechanism of dietary intervention targeting microbial metabolic remodeling is revealed, ultimately providing a reference for MHD patients' dialysis supplementary therapy based on intestinal microbiota.
