| 1 | 矿物质营养中的螯合物与配位体显示文摘金属可与许多有机分子发生反应而生成可溶性络合物。其中一些称为螯合物。整合物通常含有包括一个金属离子在内的5~6员杂环。根据Kincaid(1989)定义,螯合剂必须至少拥有两个基团,其中每一个基团都能提供一个电子对,并且两个基团的位置应能使其和该金属原子形成一个环状结构。在利用矿物质的许多反应中已鉴明了一些自然产生的螫合物。例如某些细菌可向周围环境中分泌赘合剂与铁结合,微生物还可制造钴胺素物质(包括维生素B_(12))。动物能合成一种卟啉环,该环能与铁和其他金属形成络合物。另外。 | 徐子伟 J.

| 6 | 结肠直肠癌术后POSSUM、P-POSSUM及结肠直肠POSSUM预测术后病死率的比较显示文摘PURPOSE:POSSUM(Physiologic and Operative Severity Score for enumeration of Morbidity &Mortality)and P-POSSUM have been validated as scoring tools for the prediction of postoperative complications in general surgical patients.More recently a colorectal-specific POSSUM has been developed for mortality prediction.This study was designed to evaluate and compare the accuracy for mortality prediction of POSSUM,P-POSSUM,and colorectal POSSUM after major and complex major colorectal procedures.METHODS:The relationship between the observed and expected morbidity and mortality was examined in 347 consecutive patients(321 elective,26 urgent)undergoing amajor or complex major colorectal resection using POSSUM,P-POSSUM,and Colorectal POSSUM.The accuracy of using these scoring tools to predict mortality was assessed using Receiver Operator Characteristic curve analysis.RESULTS:A total of 347 consecutive patients(median age,69(range,34-92)years)were assessed.Seventy-one patients(20.5 percent)suffered a postoperative complication and 15 patients(4.3 percent)died.The observed∶expected POSSUM ratio for morbidity was 0.71 and mortality 0.68.The area under curve from Receiver Operator Characteristic curve analysis for POSSUM was 0.752.The observed∶expected mortality ratio for P-POSSUM was 0.71,and the area under curve from Receiver Operator Characteristic curve analysis was 0.749.The observed∶expected mortality ratio for colorectal POSSUM was 0.75,and the area under the curve from Receiver Operator Characteristic curve analysis was 0.781.CONCLUSIONS:Colorectal POSSUM provides comparable prediction of mortality risk after colorectal resection compared with POSSUM and P-POSSUM. | Ramkumar T.
