Objective To study the clinical value of bedside ultrasound in predicting the fluid responsiveness in pa?tients with septic shock in intensive care unit (ICU). Methods Forty-two mechanically ventilated patients with septic shock who admitted to ICU of the Affiliated Hospital of North China University of Science and Technology from January 2015 to April 2015 were included in this study. All patients were treated with volume expansion (VE) text. Hemodynamics in?dexes were obtained by ultrasound before and after each test, including stroke volume (SV), aortic peak blood flow velocity variation rate of breathing (△VpeakAO), inferior vena cava expansion index (△IVC) and brachial artery maximum speed vari?ation rate (△VpeakBA). Clinical data and central venous pressure (CVP) were recorded. Based on the responsiveness of SV, patients were divided into responsive group (R) and non-responsive group (NR), respectively. The differences of the above in?dexes were compared between two groups. The correlation of△IVC,△VpeakAO,△VpeakBA and△SV was determined. The role of the hemodynamic index for predicting volume responsiveness was evaluated by receiver operating characteristic ROC curves. Results A total of 47 VE tests were performed in 42 patients, 25 in R group and 22 in NR group. Before VE test, the hemodynamics indicators of△IVC,△VpeakAO and△VpeakBA were significantly higher in R group compared with those of NR group (P<0.05). The values of△IVC,△VpeakAO and△VpeakBA were positively correlated with△SV in two groups. The areas under the ROC curve of the hemodynamics indicators were 0.825, 0.853 and 0.866 for △IVC, △VpeakAO and△VpeakBA, and they all showed high sensitivity and specificity. Conclusion The hemodynamic index measured by bedside ultrasound can predict the volume responsiveness in mechanically ventilated patients with septic shock fluid therapy, and which can be used to fluid therapy with a high degree of specific and sensitivity in clinical practice.

Objective: To investigate the ultrasound evaluation on lfuid responsiveness in patients with septic shock. Methods: There 42 septic shock patients treated by mechanical ventilation in our hospital from 2015-01 to 2015-04 were studied. All patients received volume expansion (VE) text, ultrasound examination was conducted to measure hemodynamic parameters of inferior vena cava variation rate of breathing (ΔIVC), aortic peak blood lfow velocity variation rate of breathing (ΔVpeakAO), brachial artery maximum speed variation rate (ΔVpeakBA) and stroke volume (ΔSV) at before and after text. Based on the response to VE text, the patients were divided into 2 groups as Responsive group and Non-responsive group, the above indexes and their correlations to ΔSV were analyzed. The clinical values of those parameters for predicting volume responsiveness were evaluated by ROC curves. Results: A total of 47 VE tests were conducted in 42 patients including 25 cases in Responsive group and 22 cases in Non-responsive group. Before VE test, the parameters of ΔIVC, ΔVpeakAO and ΔVpeakBA were higher in Responsive group than Non-responsive group; ΔIVC, ΔVpeakAO and ΔVpeakBA were obviously related to ΔSV (r=0.631, 0.668 and 0.619). The area of ΔIVC, ΔVpeakAO and ΔVpeakBA under ROC curves were 0.817, 0.853 and 0.866 respectively, they were all with the high sensitivity and speciifcity. Conclusion: Ultrasound monitored hemodynamic parameters may predict the volume responsiveness in septic shock patients with mechanical ventilation, it could be used for guiding liquid treatment in relevant patients.

Objective To explore the effects of adriamycin-loaded immuno-nanoparticles on multidrug resistance (MDR) of hepatoma cell line SMMC-7721/ADM. Methods The cytotoxicity of the adriamycin-loaded immuno-nanoparticles on the bepatoma cell line SMMC-7721/ADM in vitro and the tumor cell-binding ability of adriamycin-loaded immuno-nanoparticles were detected. Results The effect of the cytotoxicity of adriamycin-loaded immuno-nanoparticles on the hepatoma cell line SMMC-7721/ADM was significantly better than that of adriamycin-loaded nanoparticles. Adriamycin-loaded immuno-nanoparticles had the specific binding ability with the hepatoma cell line SMMC-7721/ADM. Conclusions Adriamycin-loaded immuno-nanoparticles can overcome the MDR of the tumor in vitro. The mechanism may be that immuno-nanoparticles could adhere to the tumor cell membrane, and the release of the loaded adriamycin creates a high local concentration in the extracellular medium. The increased concentration gradient improves the diffusion of adriamycin from the extracellular medium to the intracellular medium.
