BACKGROUND: Dexmedetomidine has already been used in septic patients as a new sedative agent, few studies have examined its effects on immunomodulation. Therefore, the authors have designed a controlled experimental study to characterize the immunomodulation effects of dexmedetomidine in the cecal ligation and puncture(CLP) model in rats. METHODS: After CLP, 48 Wistar rats were randomly allocated into four groups:(1) CLP group;(2) small-dose treatment group(2.5 g·kg^(-1)·h^(-1));(3) medium-dose treatment group(5.0 g·kg^(-1)·h^(-1)); and(4) large-dose treatment group(10.0 g·kg^(-1)·h^(-1)). HLA-DR and plasma cytokine(IL-4, IL-6, IL-10 and TNF-α) levels were measured, and the mean arterial blood pressure(MAP), heart rate(HR), arterial blood gases, lactate concentrations and mortality were also documented. RESULTS: The HLA-DR level, inflammatory mediator levels, MAP and HR had no obvious changes among Dexmedetomidine treatment groups(DEX groups). Compared with the CLP group, the DEX groups exhibited decreased HLA-DR levels(P_(group)=0.0202) and increased IL-6 production, which was increased at 3 h(P= 0.0113) and was then attenuated at 5 h; additionally, the DEX groups exhibited decreased HR(P<0.001) while maintaining MAP(P_(group)=0.1238), and remarkably improving lactate(P<0.0001). All of these factors led to a significant decrease in the mortality, with observed rates of 91.7%, 66.7%, 25% and 18% for the CLP, DEX2.5, DEX5.0, DEX10.0 groups, ***: Dexmedetomidine treatment in the setting of a CLP sepsis rat model has partially induced immunomodulation that was initiated within 5 h, causing a decreased HR while maintaining MAP, remarkably improving metabolic acidosis and improving mortality dosedependently.

AIM: To evaluate the preventive effects of phosph-orus-32 glass microspheres (P32-GMS) in the recurrence of massive hepatocellular carcinomas (HCCs) after tumor resection. METHODS: Twenty-nine patients with massive HCCs received local P32-GMS implantation after liver tumors were removed,while the other 38 patients with massive HCCs were not treated with P32-GMS after hepatectomies. The radioactivity of the blood,urine and liver were examined. The complications,HCC recurrence and overall survival rates in the patients were analyzed. RESULTS: P32-GMS implanted in the liver did not cause systemic absorption of P32. There were no significant differences of postoperative complications between the patients with and without P32-GMS treatment. The short-term (six months and 1 year) and long-term (2,3 and over 3 years) recurrence rates in patients who received P32-GMS radiotherapy were signifi cantly decreased,and the overall survival rates in this group were signifi cantly improved. CONCLUSION: P32-GMS implantation in the liver can significantly decrease the postoperative recurrence and improve the overall survival in HCCs patients after hepatectomy. This therapy may provide an innovative method in prevention of HCC recurrence after operation.

Tungsten-based materials are one of the most important candidates for the plasma facing materials（PFMs） of future fusion reactors,and it is necessary to study the properties of tungsten-based materials under the service conditions of fusion devices to ensure the long-term steady-state operation of future fusion *** this paper,different tungsten-based materials made by the same rotary swaging process are selected to simulate the transient thermal loads on the PFMs of a fusion reactor using an electron beam,and thermal load experiments are carried out by changing the power density of a loading pulse and the pulse *** is found that different tungsten-based materials made by the same process have large differences in thermal shock resistance,and the doped tungsten materials（W-K and W-La2O3） are significantly better than the pure tungsten materials with the increase in thermal shock power density and the number of cycles,especially the W-K materials,which have excellent performance.

作者： xiang NIU Hui LIU Daren yu Plasma Propulsion Laboratory Harbin Institute of TechnologyHarbin 150001China

Many high-precision space missions need thrusters to produce thrust with low noise to compensate for disturbances and ensure satellite platform stability. Microwave ion thruster is characterized with a wide thrust range and potential for these missions. A cost-effective and accurate mathematical model is crucial for mHz-frequency thrust noise analysis and feedback controller design. The Particle-In-Cell(PIC) and global models are two common simulation tools. The PIC model is characterized with high accuracy but huge computation cost, which is difficult to analyze long-time performance characteristics. Now, the global model is only used for the discharge chamber with low accuracy and cannot reflect ion extraction properties. In this paper, an integrative mathematical model is built for a 1-cm microwave ion thruster and can reflect ion beamlet divergence and impingement on the Accelerator Grid(AG). Simulation results show good agreement with experiments at 0.06 sccm. However, the model demonstrates worse consistency with experiments when the flux increases to 0.1 sccm, which may be because the influence of neutral gas on the Electron Cyclotron Resonance(ECR) is not considered in the model. A long-time(1000 s) simulation is conducted with this model under 35 μN. It takes 3 hrs, and the thrust noise reaches 1 μN/Hz^(0.5) at 1 mHz.

Background： Urine output （UO） is an essential criterion of the Kidney Disease Improving Global Outcomes （KD1GO） definition and classification system tbr acute kidney injury （AKI）, of which the diagnostic value has not been extensively studied. We aimed to determine whether AKI based on KDIGO UO criteria （KDtGOLro） could improve the diagnostic and prognostic accuracy, compared with KDIGO serum creatinine criteria （KDIGOscr）.Methods： We conducted a secondary analysis of the database of a previous study conducted by China Critical Care Clinical Trial Group （CCCCTG）, which was a 2-month prospective cohort study （July 1,2009 to August 31,2009） involving 3063 patients in 22 tertiary Intensive Care Units in Mainland of China. AKI was diagnosed and classified separately based on KDIGOt,o and KDlGOsc,. Hospital mortality of patients with more severe AKI classification based on KDIGOvo was compared with other patients by univariate and multivariate regression analyses. Results： The prevalence of AKl increased from 52.4% based on KDIGOscr to 55.4% based on KD1GOsc~ combined with KDIGOuo. KDIGOv~~ also restllted in an upgrade of AKI classification in 7.3% of patients, representing those with more severe AK1 classification based on KDIGOvo. Compared with non-AKI patients or those with maximum AKI classification by KDIGOscr, those with maximum AKI classification by KDIGOuo had a significantly higher hospital mortality of 58.4% （odds ratio [OR]： 7.580, 95% confidence interval [CI]： 4.141-13.873, P 〈 0.001）. In a multivariate logistic regression analysis, AKI based on KDIGOuo （OR： 2.891, 95% CI： 1.964-4.254, P 〈 0.001）, but not based on KDIGOscr （OR： 1.322, 95% CI： 0.902-1.939, P = 0.152）, was an independent risk factor for hospital mortality. Conclusion： UO was a criterion with additional value beyond creatinine criterion for AKI diagnosis and classification, which can help identify a group of patients with high risk of death.
