Objective To investigate the status of clinical using of blood products in Shanghai area,clinicians' understanding on transfusion knowledge and consciousness of prevention of transfusion risk.Methods Two hundreds of clinicians who were randomly selected from level two and above hospitals of Shanghai were inquired by questionnaire.Data including understanding of transfusion techniques,prevention of transfusion risk,application of blood components and grasp of new techniques were collected and analyzed.Results Among all interviewed clinicians,those who realized the importance of transfusion on clinical work,who understood the basic contents of clinical guideline for transfusion issued by Ministry of Health People's Republic of China,and who had the basic knowledge of blood component products and transfusion applications account for 62%,60% and 81% respectively.But only 28% clinicians knew all the side effects,27.3% learned the new techniques of transfusion,including leukocyte reduced,virus elimination,clinical application of irradiation.This investigation also showed 97% clinicians would like to accept training of transfusion,68% thought they need more relevant information about prevention of transfusion risk.Conclusions Clinicians in Shanghai area had the basic knowledge of clinical guideline for transfusion,but some knowledge of transfusion were insufficient including blood components and their applications,side effects and new techniques of transfusion.Clinicians in Shanghai had active response for being trained on knowledge of transfusion.

Objective To observe the survival of EAE rats after recombinant adenovirus NgR specific RNA interference(Ad-shRNA-NgR) transfected the brain tissue of the experimental autoimmune encephalomyelitis(EAE),and provide the basis for EAE intervention.Methods EAE rats were randomly divided into high,medium,low and control groups(20 rats in each group).The lateral ventricle of EAE rats were injected with a titer of 1×1011 pfu/mL,1×1010 pfu/mL and 1×109 pfu/mL Ad-shRNA-NgR.The survival of EAE rats at third and seventh days after injection was observed.Results The survival rate of EAE rats of the high titer group was significantly lower than those of the middle titer group and low titer group at third and seventh days after Ad-shRNA-NgR transfected into EAE brain tissue.There was no significant difference in survival rate in middle titer group,low titer group and control group.Conclusion The titer of Ad-shRNA-NgR is safe in the experiment of EAE rats from 1×1010 pfu/mL to the range of 1×109 pfu/mL.

In order to understand the alcohol's toxicity to the quantitative alternations of synapses in mouse visual cortex, the expression of synaptophysin after prenatal alcohol exposure was investigated. In present study, the experimental mice at P0, P7, P14 and P30 were grouped, as control, 2 g x kg(-1) alcohol treatment and 4 g x kg(-1) alcohol treatment. The pre-synaptic elements which were used to represent synapses were marked with synaptophysin (a synaptic vesicle associated protein) by immunocytochemistry technique. The synaptophysin positive boutons in layer VI of visual cortex were imaged under laser confocal microscope. With stereological methods, the number cal density of synapse in visual cortex was calculated in different groups at various ages. Moreover, Western blotting was carried out to detect the expression of synaptophysin in visual cortex. The results showed that prenatal alcohol exposure could cause synaptic loss with long-term effect and in a dose dependent manner. For instance, there were significant difference among the different treatment groups of P0, P14 and P30 as well (P < 0.05). Western blotting supported the results of immunofluorescent labeling. In conclusion, prenatal alcohol exposure can induce the synaptic loss dose dependently and with long-term effect. Our findings implicate that the synaptic loss with long-term effect in CNS probably contributes to the lifelong mental retardation and memorial lowliness associated with childhood FAS.

Objective: To investigate the feasibility for reconstructing an aortic arch by a new integrated two-branched stent graft releasing in experimental canine thoracic aorta simulation system.
Methods: A new type of integrated two-branched stent graft was developed and placed in the canine thoracic aorta, the stent graft releasing in a simulated system was conducted under X-ray guidance to monitor the operating process and to explore the feasibility for invitro sent graft releasing.
Results: The new two-branched stent graft was successfully deployed in canine thoracic aorta simulation system. The releasing process was smooth, two small stent grafts were well landing, and all stent grafts were fully expanded and properly positioned.
Conclusion: Our new two-branched stent graft could successfully reconstruct the aortic arch in experimental canine. The thoracic aorta releasing system may better and truly simulate the whole process of endovascular aortic repairing, which provides a good foundation for further animal experiments.

Objective To evaluate the clinical application of susceptibility-weighted imaging(SWI) in the early diagnosis of massive cerebral infarction with hemorrhage and analysis of collateral circulation.Methods Fifty patients with massive cerebral infarction underwent MRI (T1WI,T2WI,DWI,MRA and SWI) scan in acute stage and decubation respectively in Hanrison International Peace Hospital from January 2012 to January 2014.Analysis T1WI,T2WI,DWI,MRA and SWI differences in the delection of cerebral infarction with hemorrhage and analysis of Collateral circulation.Record the magnetic resonance angiography hemorrhagic transformation and display the ischemic area of collateral circulation in the detection of cerebral infarction remodeling differences.Results (1)SWI detected out 18 cases of cerebral infarction with hemorrhage (36%),including 14 cases of hemorrhagic infarction(HI) type(28%),4 cases of parenchymal hemorrhage(PH) type 8%).MRI detected 11 cases of cerebral infarction with hemorrhage (22%),including 7 cases of HI type 14%),4 cases of PH type (8%).SWI detected 106 focuses,the detection rate was 100%,MRI detected only 26,and the detection rate was 32.51%,and the missing mainly for micro hemorrhage.There was statistical significance between the groups(x2 =21.045,P<0.05).(2) SWI can display the condition of micrangium in the area of cerebral infarction clearly.The number of micrangium decreased or disappeared in acute stage,but the micrangium increased in decubation.The ratio of capillary vessels increased to 66%.MRA detected 82% of criminal vessel in patients with cerebral infarction.Conclusion SWI is more sensitive than conventional MR in the early diagnosis of massive cerebral infarction with hemorrhage.MRA combined with SWI could not only detect the criminal vessel of cerebral infarction area,but also monitor the reconstruction of collateral circulation in the infarction region,and there will be extremely valuable to the treatment massive cerebral infarction and evaluation of prognosis.
