研究目的:

(1) 标准化的母乳强化配置方案的建立:通过比较捐赠母乳喂养组与亲母强化捐赠母乳组在胎便排出时间、生化指标及免疫指标的差异,明确亲母母乳强化捐赠母乳是否可优化早产儿的营养吸收和免疫状态; (2) 基于“微生物组-代谢组-免疫调控”多维度解析10%亲母母乳强化的生物学效应:结合16S rRNA测序、非靶向代谢组学、短链脂肪酸,分析两组早产儿肠道菌群多样性、代谢产物酸衍生物、短链脂肪酸含量等差异,阐明亲母母乳强化捐赠母乳对早产儿肠道微生态的调控作用及其关键机制; (3) 精准喂养模型构建:整合临床疗效数据与多组学特征(微生物标志物、代谢产物、免疫指标),开发早产儿个体化精准喂养模型。  

Objectives of Study:

(1) Establishment of a standardized breast milk reinforcement configuration plan: By comparing the differences in fecal excretion time, biochemical indicators, and immune indicators between the donated breast milk group and the maternal reinforcement donated breast milk group, it is clear whether maternal breast milk reinforcement donated breast milk can optimize the nutritional absorption and immune status of premature infants; (2) Multi dimensional analysis of the biological effects of 10% maternal breast milk enhancement based on "microbiome metabolome immune regulation": combined with 16S rRNA sequencing, untargeted metabolomics, and short chain fatty acids, analyze the differences in gut microbiota diversity, metabolite acid derivatives, and short chain fatty acid content between two groups of premature infants, and elucidate the regulatory role and key mechanisms of maternal breast milk enhancement and donated breast milk on the gut microbiota of premature infants; (3) Construction of Precision Feeding Model: Integrating clinical efficacy data with multiple omics features (microbial markers, metabolites, immune indicators) to develop an individualized precision feeding model for premature infants.
