In this review, we summarized the evidence of randomized controlled trials （RCTs） which compared NS with other solutions in critically ill patients. The results showed that when compared with 6% hydrox- yethyl starch （HES）, NS may reduce the onset of acute kidney injury （AKI）. However, there is no significant different in mortality and incidence of AKl when compared with 10% HES, albumin and buffered crystalloid solution. Therefore, it is important to prescribe intravenous fluid for patients according to their individual condition.展开更多

Methods： BALB/c mice were randomly divided into control, NS, HTS, and HES resuscitation groups. Three subgroups （n=8） in each resuscitation group were marked as 2, 24, and 72 h. Flow cytometry was used to detect the MDSCs, monocytic MDSCs （M-MDSCs）, and granulocytic/neutrophilic MDSCs （G-MDSCs） in peripheral blood nucleated cells （PBNCs）, spleen single-cell suspension, and bone marrow nucleated cells （BMNCs）. Results： The MDSCs in BMNCs among three resuscitation groups were lower 2 h after shock, in PBNCs of the HTS group were higher, and in spleen of the NS group were lower （all P〈0.05 vs. control）. The M-MDSC/G-MDSC ratios in PBNCs of the HTS and HES groups were lower （both ,P〈0.05 vs. control）. At 24 h, the MDSCs in PBNCs of the NS and HTS groups were higher, while the spleen MDSCs in the HTS group were higher （all P〈0.05 vs. control）. The M-MDSC/ G-MDSC ratios were all less in PBNCs, spleen, and BMNCs of the NS and HTS groups, and were lower in BMNCs of the HES group （all P〈0.05 vs. control）. At 72 h, the elevated MDSCs in PBNCs were presented in the HTS and HES groups, and in spleen the augment turned up in three resuscitation groups （all P〈0.05 vs. control）. The inclined ratios to M-MDSC were exhibited in spleen of the NS and HTS groups, and in PBNCs of the NS group; the inclination to G-MDSC in BMNCs was shown in the HES group （all P〈0.05 vs. control）. Conclusions： HTS induces the earlier ele- vation of MDSCs in peripheral blood and spleen, and influences its distribution and differentiation, while HES has a less effect on the distribution but a stronger impact on the differentiation of MDSCs, especially in bone marrow.展开更多
