Application of dietary fiber in clinical enteral nutrition: A meta-analysis of randomized controlled trials

AIM: To evaluate the effects of dietary fiber (DF) as a part of enteral nutrition (EN) formula on diarrhea, infection, and length of hospital stay. METHODS: Following electronic databases were searched for randomized controlled trials about DF: Chinese Biomedicine Database (CBM), MEDLINE, EMBASE and Cochrane Controlled Trials Register. RevMan 4.1 was used for statistical analysis. RESULTS: Seven randomized controlled trials with 400 pat-ients were included. The supplement of DF in EN was compared with standard enteral formula in five trials. Combined analysis did not show a significant reduction in occurrence of diarrhea, but there were valuable results for non-critically ill patients. Combined analysis of two trials observing the infection also did not show any valid evidence that DF could decrease the infection rate, though the length of hospital stay was reduced significantly. CONCLUSION: Based on the current eligible randomized controlled trials, there is no evidence that the value of DF in the diarrhea can be proved. Though length of hospital stay was shortened by the use of DF, there is no available evidence in preventing infection by DF. Further studies are needed for evaluating the value of DF in EN.

关于H-C-O体系析碳状态分布图的开发与应用

针对冶金领域的富氢直接还原气体制备、竖炉直接还原过程、高炉煤气循环利用以及化工领域的天然气制氢等涉及CH_(4)-H_(2)-CO-H_(2)O-CO_(2)体系尤其是更具广泛代表性的H-C-O体系的析碳共性问题,建立一种便捷、快速、易操作、普适性强地判断体系是否析碳的方法十分必要。在“H-C-O体系质量与化学平衡衡算图”基础上,基于多相、多反应共存体系的平衡原理,确定了包括体系温度、总压、体系内n_(H_(2))/n_(CO)比值等各种操作条件下对应的临界析碳点坐标(nO/nC,nH/nC),连接相同参数的临界析碳点得到对应的临界析碳曲线,构建了“H-C-O体系析碳状态分布图”,开发了一种可准确把握生产状态、确定体系是否发生析碳的新方法,建立了H-C-O体系析碳状态分布理论,为选择控制析碳工艺参数提供了理论基础;为了解决制作“H-C-O体系析碳状态分布图”时存在计算较繁杂的不足,开发了“H-C-O体系析碳状态分布图”分析专用软件,并结合已知的生产实践以及文献数据,验证了“H-C-O体系析碳状态分布图”的合理性和实用性。研究表明,论文提出的确定体系是否发生析碳的新方法普适性广、包容性强,“H-C-O体系析碳状态分布图”不仅能简捷、快速、准确地判别某给定条件下体系是否会发生析碳问题,而且可以给出既能防止体系析碳又能最大限度降低天然气制氢工序能耗和成本的努力方向,为实际生产降本、降耗、稳定、顺行提供有效的指导。
