Objective To evaluate the diagnostic value of multi-slice thrce-dimensional computed tomographic angiography(MS-CTA) with volume rendering(VR) for Moyamoya disease.Methods MS-CTA of 25 patients with Moyamoya disease verified by DSA were restrospectively analyzed.Source images were got by GE Lightspeed pro scanner.VR was adopted to reconstruct 3D images in all cases.Results Of 25 CT precontrast,13,12 cases showed infarction and hemorrhage respectively,while 11 cases had dialated vessels in thalamus-basal ganglia region on CT.Accuracy of stenosis or occlusion of the bifurcation of ICA, proximal portion of the ACA or MCA was 88.0% (22/25) by MS-CTA.MS-CTA overestimated the degree of stenosis,MS-CTA misdiagnosed 3 cases(12.0%)with stenosis to occlusion.MS-CTA showed fewer small Moyamoya vessels than DSA.MS-CTA only demonstrated 6 cases(25.0%)with collateral vessels.Conclusion CT is still the conventional method for detecting secondary lesions to Moyamoya disease.CT and MS-CTA can accurately diagnose Moyamoya disease.

A catheter(0.3 mm O.D.)was introduced into the external carotid artery(ECA) lumen into the lumen of the internal carotid artery(ICA), then it was gently advanced to the intracranial segment of ICA until the intraluminal catheter was 2~3mm from the origin of MCA. At this point thrombin were injected into ICA to induce thrombosis. Behavior disorders were observed at 3, 6, 12h after the operation. Willis circle, infarct volume and histopathologic changes were examined 12 hours after operation. The results showed that the model had stable behavior disorder score and infarct volume. Mixed thrombus could be observed at the origin of the MCA. Infarction volume of this model was similar with that of the model developed by linear occlusion of MCA in our laboratory. The model has the advantages of easy operation, reliable ischemia and reproducible infarct volume. It may be useful in documenting the safety and efficacy of thrombolytic therapies.

Objective:To determine the mechanism of sunitinib-induced autophagy in renal cell carci-noma cells.Methods:MTS assay was applied to detect the cell viability alteration under the treatment of sunitinib (2,8 μmol /L).The sunitinib-induced autophagy as well as cell apoptosis was measured and compared after knocking down autophagy-related protein Beclin1 and microtubule associated protein 1 light chain 3 fusion protein (LC3)by RNA interference.The transmission electron microscope was used to observe the formation of autophagosomes in ACHN cells.The fluorescence microscope was used to mo-nitor distribution and aggregation of endogenous LC3-Ⅱ.The expressions of protein such as LC3-Ⅱ,the autophagic regulation molecules protein kinase B /mammalian target of rapamycin (Akt/mTOR)and the symbol of apoptosis poly ADP-ribose polymerase (PARP)were capable to be detected by immunoblotting assay.Results:Sunitinib was able to significantly trigger cell viability loss in the renal carcinoma cell ACHN,which was both in a concentration-dependent and time-dependent manner (P <0.05 ).After reducing the autophagy by knocking down Beclin1 and LC3,the number of cleavage of PARP was in-creased remarkably,whereas there was nearly not any cleavage in the mock group.By the transmission electron microscope,there were more autophagic vacuoles in ACHN cells after being administrated with sunitininb compared with the control.And the nuclear-to-cytosol translocation as well as aggregation of LC3-Ⅱ was presented after sunitinib treatment by the fluorescence microscope,which was the proof of the enhanced autophagy.According to the immunoblotting,sunitinib was able to increase the accumula-tion of LC3-Ⅱ.At the same time,the result of sunitinib combined with chloroquine,a drug which blocked the fusion of autophagosomes and lysosomes,demonstrated that the increasing amount of LC3-Ⅱwas due to the enhanced autophagy flux by sunitinib treatment in ACHN cells.However,phosphorylation of Akt as well as mTOR was decreased at the same time.The rapamycin (mTOR inhibitor)or knocking down Akt subunits could change the sunitinib-induced LC3-Ⅱ accumulation,whereas overexpression of Akt subunits decreased the autophagic flux,indicating that Akt/mTOR was the target of sunitinib in auto-phagy.Conclusion:Sunitinib induced autophagy via suppressing Akt/mTOR pathway,and the auto-phagy was involved in apopotosis.

Objective To assess the risk of malnutrition in elder home-care patients through mini nutritional assessment (MNA) and study the correlations between total MNA score and 18 individual questions in this patient group.Methods In May 2011,62 elder home-care patients from our center answered the MNA questionnaire.And the results were used to analyze the correlations between total MNA score and individual questions and the correlations among MNA classifications and body mass index(BMI),mid-arm muscle circumference (MAMC) and calf circunference (CC).Results According to MNA,18% were malnourished ( 11/62 ),47% at risk of malnutrition ( 29/62 ) and 35% well-nourished ( 22/62 ) ; BMI,independence,mobility,neuropsychological problems,ingesting method,MAMC,CC and selfperceived nutritional status,self-perceived health status showed strong correlations with total MNA score (0.601,0.600,0.666,0.611,0.627,0.618,0.726,0.612,0.672,P <0.05).And weight loss within a month,number of daily meals and intake of drinks showed weak correlations with total MNA score (0.35,0.319,0.288,P < 0.05 ).Positive correlations existed among MNA classifications and BMI,MAMC,CC (15.45,19.85,31.89,P<0.05).Conclusions The elder home-care patients have a high risk for malnutrition.Half of 18 individual questions are strongly correlated with total MNA score in this patient group.

( 1 ) Semicircular canal not visualized equal to score 0 ; some visualized equal score 1 ; full visualized equal score 2.(2)There were high-signal and low-signal in the vestibule,low-signal areas above the lateral semicircular canal plane equal score 6 ; low signal areas down to lateral semicircular canal plane equal score 3 ; no higher signal in the vestibule area equal score 0.( 3 ) Basal turn of cochlea:full visualized equal score 3; part visualized equal score 2; scala vestibule of basal turn smaller than scala tympani equal score 1 regardless of full or visualized in basal turn; no visualized equal score 0. Medial turn of cochlea:full visualized equal score 2 ; part visualized equal score 1 ; no visualized equal score 0.Apical turn of cochlea: visualized equal score 1 ; no visualized equal score 0. One radiologist scored all cases with double blind. SPSS 17.0 software was used to conduct multiple independent-samples nonparametric tests,multivariate Logistic regression, and ROC curve analysis. Evaluate the sensitivity and specificity for diagnosis of Meniere's disease with the scoring system. Results ( 1 ) Meniere's disease summation score 0 to 12,median 9 (quarter spacing 4.5 ) ; no symptoms group summation score 15 to 18,median 17 (quarter spacing 3),two group differences has statistics significance (Wilcoxon rank and inspection U =-9.118,P =0.00).(2)Based on summation score for the diagnosis of Meniere's disease,tangent point was 14.5,Youden index 0.969,specificity 100.0%,sensitivity 96.9%.( 3 ) Let cochlear,vestibular,semicircular canal scoring for association variable,Logistic regression model:LogitP =61.216 - 7.381 × vestibular -3.056 × canal,based on the P value of ROC curves,diagnostic cut-off point 0.651 (vestibular ≤ 3 or semicircular canals ≤ 4 points ),Youden index 96.9%,specifisity 100.0%, sensitivity 96.9%.Conclusions Perilymphatic space of gadolinium contrast MR score in distinguishing Meniere's disease have practical value,any case meet one of following point could be diagnostic:( 1 ) Perilymphatic space of gadolinium contrast MRI total less than 14.5 ; (2) Vestibular low signal areas down more than lateral semicircular canal plane,namely vestibular score value ≤3;( 3 )Semicircular Canal scoring value ≤4.
