RESUMEN
Objective To explore the effects of heating intravenous fluid infusion and blood transfusion based on guidelines in severe trauma patients with hypothermia. Methods A total of 40 severe trauma patients with hypothermia admitted from July 2014 to December 2015 were enrolled as the control group treated with routine measures to maintain the body temperature at normothermia by such as electrical heating blanket; other 40 severe casualties with hypothermia admitted from January 2016 to July 2017 were recruited as the warming up group treated with heating intravenous fluid infusion and blood transfusion by hot water bath in addition to the routine measures for keeping body temperature at normothermia. The differences in core body temperature, prothrombin time, activated partial thromboplastin time, incidence of shivering and mortality rate were compared between the two groups. Results There was statistically signifi cant difference in core body temperature at 0.5 h, 1.0 h, 1.5 h, 3.0 h between the two groups (P<0.05). Though the prothrombin time and shivering were improved after warming up in both groups, and there were significant differences in prothrombin time at 3.0 h after warming up and the incidence of shivering between two groups(P<0.05).There was no signifi cant difference in mean arterial pressure at all seven intervals between two groups. Conclusion The heating intravenous fl uid infusion and blood transfusion had remarkable effects to prevent hypothermia, improves blood coagulation and reduced the incidence of shivering to provide more simple and convenient warming up intervention for clinical practice.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the effect of triptolide on the differentiation of human Th17 cells.</p><p><b>METHOD</b>Human peripheral blood mononuclear cells, purified CD4+ T cells and CD4+CD45RA- memory T cells were treated with various concentrations of triptolide in vitro. Cell proliferation was determined by MTT assay. Flow cytometry was used to analyze the intracellular expression of IL-17 and IFN-gamma. Cytokine production of IL-17 and IFN-gamma was measured by ELISA.</p><p><b>RESULT</b>Cell proliferation, intracellular expression of IL-17 and IL-17 secretion were inhibited by triptolide in a dose-dependent manner. IFN-gamma expression and production were also inhibited by triptolide.</p><p><b>CONCLUSION</b>Triptolide inhibits the differentiation of human Th17 cell. The observation may indicate at least one of the mechanisms of the immunosuppressive and anti-inflammatory effects of triptolide.</p>
