Objective To investigate the association between brain structure abnormalities and neuropsychology impairment in CAD patients.Methods Nineteen patients with CAD and 1 7 healthy adults were examed with MRI,and T1 WI,T2 WI,FLAIR,DWI and DKI image were performed,and then comparing the acquired MRI findings between two groups.Results Significant differences were observed for MK values in splenium and body of the corpus callosum,left cerebellar hemisphere and amygdala cerebelli.MK values of CAD group were lower than those of healthy group in these regions,and differences were statistically significant(P <0.05). There were significant correlation between MK values of the left amygdala cerebelli and MoCA scores in CAD group.Conclusion DKI could detect the changes of brain tissue microstructure in CAD patients early.The correlation between MK and neuropsychologi-cal function provides an important basis for early diagnosis and treatment.

Objective To evaluate the effect of endovascular embolotherapy treatment of carotid cavernous fistulas(CCF) via superior ophthalmic vein(SOV).Methods From June 1996 to June 2006,a total of 32 patients(16 female) with complex CCF underwent endovascular embolotherapy treatment through the SOV.All of the patients visited doctor due to ocular signs and symptoms.Nine patients with direct CCF had previously undergone partial arterial balloons embolotherapy.The other 23 patients were hard mater CCF,and of which 3 had underwent NBCA,embolotherapy with line section or PVA particle.In the angiographic suite all patients underwent general anesthesia,SOV was catheterized through the eyebrow incision.Cavernous sinus was packed with free coils,detachable coils or balloons and NBCA.Results Complete embolism of the arteriovenous shunt was achieved in 81.3%(26/32).A minor residual shunt(without cortical or ocular drainage) remained in 12.5%(4/32).Only SOV was occluded in 6.2%(2/32).All patients were clinical improvement without complications.No death and permanent disability occurred.No recurrence was observed during follow-up of mean time of 3.5 years in 22 outpatients.Conclusion The operative approach to SOV is straightforward and several kind of embolic materials can be used to embolize the cavernous sinus.Endovascular occlusion of cavernous sinus through the SOV is an efficient and safe treatment in CCF.

Objective:To examine the expression of CLC-3 in colorectal tissues and the effect of CLC-3 on the viability and invasion of colorectal cancer (CRC) SW480 and SW620 cells. Methods:The mRNA levels of CLC-3 in CRC cell lines were determined by RT-PCR. CLC-3 expression was inhibited by adding DIDS or NPPB to the CRC cells. Subsequently, cell viability and invasion were assessed by CCK-8 assay and Transwell assay, respectively. In addition, the effects of DIDS and NPPB on the Wnt orβ-catenin signaling pathways were de-termined by Western blot analysis. Results:The mRNA level of CLC-3 was remarkably increased in the CRC tissues compared with that in normal colorectal tissues (P<0.05) and was positively correlated with the T stage of CRC. The blockade of CLC-3 inhibited the viability and invasion of CRC cells (P<0.05). The expression ofβ-catenin, C-myc, cyclin D1, Ki-67, and survivin were evidently reduced by the in-hibition of CLC-3 (P<0.05). Conclusion:The inhibition of CLC-3 decreases the cell viability and invasion of CRC cells by reducing the ex-pression of the proteins related to the Wnt orβ-catenin signaling pathway.

ObjectiveTo discuss the feasibility of the method that can be used to induce the model of type 2 diabetic mellitus rat and explore the characteristic of the nephropathy.The rats were fed with the high sucrose,high fat and high energy feed for a long time and then it was injected with the low dose STZ.Methods30 SD rats were selected and then it was randomly divided them into 2 groups,the control group (10 rats) and the model group (20 rats).The model group was fed with the high calorie feed forl0 weeks to induce insulin resistance and then the rats were induced to type 2 diabetes mellitus by injection of streptozocin (30 mg/kg).The rats of the model group were continually fed with the high calorie feed for 2 months.Before the end of this study,the 24-hours microalbuminuria,serum creatinine and blood urea nitrogen were detected and the periodic acid Schiff staining on the kidney were also measured.ResultsAfter the rats of the model group were established,the levels of the bodyweight,the cholesterol,the triglyceride and the insulin were [ (468.7 ± 8.8 ) g,( 1.92 ± 0.27 ) mmol/L,( 1.32 ± 0.34) mmol/L,(38.81 ± 5.39 ) mU/L ] respectively,all of them were higher than the levels in the normal group,which were [ (436.9 ± 7.4) g,(1.16 ±0.17)mmol/L,(0.8 ±0.18)mmo1/L,(21.43 ±4.19)mU/L],respectively( t =9.755,8.077,4.437,8.902,P ＜ 0.01 ).After injection of STZ for 2 weeks,the levels of the blood glucose,the insulin and the insulin resistance of the diabetes mellitus rats were [ ( 19.31 ± 1.55 ) mmol/L,( 31.31 ± 8.60) mU/L,(26.55 ± 6.33) ] respectively,it was higher than levels inf the normal group,which was[ (5.45 ±0.69) mmol/L,( 19.97 ± 3.26) mU/L,(4.82 ± 0.84) ] ( t =26.383,3.951,10.719,P ＜ 0.01 ).Before the end of this study,the levels of the blood glucose,insulin resistance,24-hours microalbuminuria,serum creatinine,blood urea nitrogen of the diabetes mellitus rats were [ ( 19.27 ± 1.97 ) mmol/L,( 16.70 ±7.51 ),(72.49 ± 8.53 ) mg/24 h,( 74.76 ± 8.38 ) μmol/L,( 19.09 ± 4.21 ) mmol/L],it was higher than the levels in the normal group,which were [ (5.62 ±0.65) mmol/L,(5.45 ± 1、33),( 15.26 ±2.20) mg/24 h,(40.81 ± 1.97) μmol/L,(9.87 ±2.13) mmol/L,t =20.961,4.657,20.623,12.495,6.352,P ＜0.01 ].And the pathological changes of the diabetes mellitus rats kidney tissues were the most serious through themethod of periodic acid-Schiff's staining (PAS).ConclusionsThe model of type 2 diabetic mellitus rat was constructed through the way of feeding the SD rats with high sucrose,high fat and high energy feed for a long time and low dose STZ.The diabetic mellitus rats had the symptom of drinking more,eating more and diuresis,and the character of this model had high levels of albuminuria,serum creatinine,blood urea nitrogen.The incrassated glomerular mesangium,the crescent-shaped focus and the glomerulosclerosis were also observed through the PAS.
