系统整合中国母乳营养数据,探究不同喂养方式对婴幼儿成长的不良影响,为婴幼儿乳粉开发提供数据支撑和对比。利用检索数据库——知网、万方、PubMed和Web of Science,全面收集2000年至2024年中国母乳喂养、人工喂养及母乳营养成分数据...系统整合中国母乳营养数据,探究不同喂养方式对婴幼儿成长的不良影响,为婴幼儿乳粉开发提供数据支撑和对比。利用检索数据库——知网、万方、PubMed和Web of Science,全面收集2000年至2024年中国母乳喂养、人工喂养及母乳营养成分数据相关文献,采用Revman和SPSS 26.0软件定量分析人工喂养及母乳喂养对婴幼儿成长的不良影响,同时探讨二胎政策实施前、后中国母乳营养成分数据差异,并剖析差异来源;此外,对比国内外市售知名婴幼儿配方奶粉与母乳的营养成分差异。经系统检索,初筛获得3217篇文献,严格遵循纳入与排斥标准,最终纳入18篇文献进行Meta分析。结果显示,母乳喂养对婴幼儿产生的不良影响显著低于人工喂养[风险比(RR)=0.58、95%置信区间(CI)(0.46,0.73),P<0.00001]。此外,通过SPSS 26.0对32篇文献中的中国母乳营养数据进行分析,构建母乳数据库,并对比二胎政策前、后的母乳数据变化。现有数据表明母乳喂养更有益于12个月内的婴幼儿成长。二胎政策开放前、后母乳营养数据的波动变化,为研发更贴近母乳的婴幼儿配方奶粉提供了数据支撑。展开更多

Additionally, another important class of natural products from Cephalotaxus plants is cephalotane diterpenoids. Since the discovery of the first member, harring-tonolide,in 1978, cephalotane diterpenoids have garnered significant attention from the scientific community due to their re-markableanti-cancer activity. The unique structural features of cephalotane diterpenoids, a 7/6/5/6-fused tetracyclic carbon skeleton and a bridged lactone, make them ideal targets for synthetic chemists. Successfully synthesizing these complex diterpenoids is of great importance for the discovery and development of anti-tumor drugs. To date, ten research groups have completed the total synthesis of 24 cephalotane diterpenoids. The latest progress in the total synthesis of cephalotane diterpe-noidsis reviewed, showcasing the importance of these innovative synthetic strategies in the efficient synthesis of complex natural products and their potential significance in advancing the field of drug discovery.展开更多
