Objective To estimate the venous thromboembolism (VTE) risk and prevention in critically ill patients admitted to ICU and discuss the appropriate strategy for prevention.Methods A total of 276 critically ill patients staying longer than 48 hours in ICU were enrolled for a retrospective single-center study.VTE risk assessment,methods for mechanical and pharmacological prophylaxis and demographic data were recorded.Simplified Caprini scores for VTE risk were counted in the first day and 7th day after admission to ICU,and were compared among internal medicine,surgery and trauma subgroups.Relationship between VTE risk and the clinic index was analyzed by Pearson test and Spearman test with SPSS 17.0 software.The prophylaxis strategy applied to patients without low risk of VTE was explored.Results Simplified Caprini scores were (8.71 ± 4.90) and (9.24-± 5.30) on the first day and the 7th day after admission respectively.Simplified Caprini score was significantly related to APACHE Ⅱ score (r =0.397,P =0.027).Meanwhile,simplified Caprini score in surgical and traumatic patients was higher than that in medical ill patients (14.02 ±2.01),(14.5 ± 1.29) vs.(6.55 ±3.98),P ＜0.01.The total rate of early prophylaxis measures used with mechanical prevention (13.43％) and pharmacological prophylaxis (5.22％) was only 18.28％ within 48 hours after admissioin of patients with highest riskof VTE.Even on the 7th day after admission to ICU,the total rate of prophylaxis measure employed with mechanical prevention (11.92％) and pharmacological prophylaxis (11.56％) for VTE was 25.83％.Conclusions Critically ill patients in ICU were subjected to extremely high risk of VTE.The VTE risk related closely to the severity of critically illness existed throughout the whole period of the ICU stay.Constant assessment for VTE risk and bleeding risk should be made with frequent assessment for critically ill patients.

Objective To investigate the value of macrophage activity imaging (MAI) in the diagnosis of brain and spinal cord lesions in rat model of multiple sclerosis(MS). Methods Twenty LEW rats were divided into 15 model rats and 5 control rats. MS animal model, experimental autoimmune encephalomyelitis (EAE) was induced by the injection of peptide 35-55 of myelin oligodendrocyte glycoprotein ( MOG35-55 ). MRI was performed on the third day of the acute stage of disease. The brain and spinal cord of rats were scanned by 3.0 T MR scanner( Siemens Trio Tim) with quadrature wrist joint coil.The T2W and T1 W images, Gadolinium enhanced T1 W images in 3D volume were obtained respectively. The MAI were obtained at 24 hours after intravenous injection of ultra small superparamagnetic iron oxide (USPIO) as contrast medium on T2WI. The workstation with special software was used for the reconstruction images of brain and spinal cord of rat in multiple orientations. Results Fifteen MOG35-55-EAE rats model of MS were successfully induced. The great majority lesions of central nervous system in acute stage were located in the brain( 58/63 ) and less in the spinal cord (5/63). The main manifestation of EAE lesions presented was hyperintensity on T2 WI and hypointensity on T1 WI, and some lesions had enhancement after Gd-DTPA injection. The EAE lesions presented as hypointensity on MAI images, but some of them were found to be isointensity on T2 WI. The enhancement pattern was discrepant between USPIO and Gd-DTPA.The sensitivity of depicting lesions of MOG35-55-EAE rat at acute stage were higher on T2WI ( 14/15 ) and MAI ( 13/15 ), and the detection rate was 100% ( 15/15 ) if they were combined. Gd-DTPA enhanced T1 WI had a lower sensitivity (7/15). All the MAI findings were negative in the control rats. Conclusions MAI can complement the drawback of conventional MRI techniques by continuously monitoring the inflammatory activity of EAE lesions, and it could raise the detection rate of EAE lesions by combining with T2WI. Gd-DTPA enhanced T1 WI monitors the breakdown of the blood brain barrier. MAI and Gd-DTPA enhanced MR imaging are complementary in the diagnosis and monitoring of EAE lesions.

Objective To estimate the clinic features of severe multiple trauma with secondary thrombocytosis as a factor influencing the prognosis.Methods A retrospective single-center study was carried out in 680 patients with severe multiple trauma survived longer than 72 hours in Chongqing Emergency Medical Center from March 2010 through March 2013.The variables including age,gender,ISS (injury severity score),APACHE Ⅱ score,splenectomy and the usages of vasopressors,blood products transfusion,hematopoietic medicines and anticoagulant were analyzed.The prognosis indices including total in-hospital mortality after 72 hours,length of hospital stay and morbidity of thrombo-embolism were explored.The clinic characteristics and prognosis of severe multiple trauma with secondary thrombocytosis (platelet count more than 450 × 109 L-1) were evaluated.T test or rank sum test was used for comparison between measurement data and Chi-square test or Fisher' s exact test was used for comparison between enumeration data.Results Thrombocytosis was identified in 99 (14.56％) patients and it occurred one week after injury with median time of 27 days (ranged from 8 days to 304 days),and maintained for (18.62±4.38) d.The median of platelet count was 584 × 109 L-1 (lowest 478 × 109 L-1,highest 1 072 × 109 L-1) in severe multiple trauma patients with thrombocytosis.The proportions of splenectomy,prolonged use of vasopressors and employment of hematopoietic medicines or anticoagulant were significantly higher in patients with thrombocytosis than those in patients without thrombocytosis (14.14％ vs.7.06％,P=0.03;62.63％ vs.39.07％,P＜0.01; 28.28％ vs.6.71％,P＜0.01; 90.91％ vs.19.45％,P＜ 0.01).The highest D-Dimer level presenting in patients with thrombocytosis during the time of platelet increasing was significantly more common than that in patients of non-thrombocytosis group 7 days after trauma [(11.68 ± 11.90) vs.(5.05 ± 5.11),P =0.004].However,the mortality,length of hospital stay and morbidity of thrombo-embolism were not significantly increased in patients with thrombocytosis compared with patients without thrombocytosis [8.08％ vs.8.78％,P=0.82; 34 d (28.5,54.5) d vs.45 d (23,67) d,P =0.41; 10.10％ vs.10.50％,P =0.91].Conclusion There was a higher rate of secondary thrombocytosis in severe multiple trauma patients.The factors such as splenectomy,vasopressors,hematopoietic medicines and so on might induce the reactive thrombocytosis in trauma patients.Thrombocytosis might increase the incidence of thromboembolism in severe multiple trauma patients without appropriate prophylactic anticoagulation.For the sake of prophylaxis,employment of anti-platelet agent might be the appropriately therapeutic strategy for patients suffering from severe multiple trauma with secondary thrombocytosis accompanying risk factors of arterial thrombo-embolism.

Objective To explore the feasibility of using clinical whole body MR scanners to investigate the intravital visibility of central nervous system (CNS) lesions in rats of multiple sclerosis (MS). Methods Ten Lewis rats were injected with the peptide 35-55 of myelin oligodendrocyte glycoprotein to make the model of MS. On a Siemens Sonata 1.5T MR scanner equipped with a flexible surface coil, rats brain and spinal cord were examined using T2-weighted and T1-weighted imaging with slice thickness of 1-2 mm. On a Siemens Trio Tim 3.0T MR-scanner equipped with a quadrature wrist coil, rats were examined using T2WI, T1WI and Gd-DTPA enhanced T1WI 3-dimensional imaging with voxel size up to 0.06-0.08 mm~3. Rat brain and spinal cord images in multiple orientations were reconstituted with special software in workstation. Results T2WI and T1WI of the lesions in MS rat brain with high spatial and contrast resolution could be obtained with clinical 3.0T MR scanner, though the image resolution of spinal cord was relatively low. The resolution of 1.5T MR was lower than that of 3.0T. Plaques in CNS of MS rats presented as hyperintense areas on T2WI and hypointense areas on T1WI. Contrast enhancement was observed as hyperintense on T1WI. Conclusion High quality images of CNS lesions canbe obtained with clinical 3.0T MR-scanner in MS rat, which offers a noninvasive access for studying CNS diseases in the rats.
