Conclusions Multif ocal bladder cancer and cancerogenic tendency of urothelium may be the risk fact ors of this disease.IVU combined with US is the main diagnostic method for the d isease.CT is recommended for the further examination.Nephroureterectomy is the p referred treatment choice for this disease.

Objective:To investigate the expression pattern of Mtsl/S100A4 in mouse spinal cord;to investigate the effects of Mtsl/S100A4 on glial cell responses.Method:The study was carried out on Mtsl/S100A4 wild type and knock-out mice.The degenerative spinal cord model was established by dorsal root or sciatic nerve injury.The de-myelinated spinal cord model was established by ethidium bromide injections.Then the expressions of S100A4,GFA P,NG2 and Mael were measured.Result:The expressions of Mtsl/S100A4 in mice spinal cord were similar to that in rats.In WT mice this protein expressed in a thin layer of fiber bundles in the tract of Lissauer,and in white matter astrocytes.There was intracellular up-regulation of Mtsl/S100A4 in white matter astrocytes of WT mice after dorsal root or sciatic nerve injury,with no difference in glial cell response between WT and KO mice.However,7 days after ethidium bromide injection,in WT mice,the astroglial reaction was restricted on operated side,where a distinct glial scar had formed.While in KO mice,no distinct glial scar formed in demyelinated area.Conclusion:Mtsl/S100A4 expression in mouse spinal cord is similar to the pattern as in rats;intracellular Mtsl/ S100A4 up-regulation does not affect glial responses in degenerative spinal cord;the presence of extracellular Mtsl/ S100A4,which entered the spinal cord after ethidium bromide induced demyelination,markedly affects the glial cell responses in demyelinative spinal cord,including glial scar formation.

Objective To explore the value of water -based material decomposition images for detection of bone marrow edema (BME)in sacroiliitis with energy spectral CT.Methods The sacroiliac (SI)joints of nine spondyloarthropathy patients with sacroiliitis (the research group)and eight healthy volunteers (the control group) were underwent MRI and energy spectral CT.The mixed energy image of energy spectral CT was reconstructed to be mono energy image.Then,the mono image was divided into water -based image and calcium image by material divid-ed and analyzed software.The SI para -articular marrow region water -calcium relative concentration of research group was compared with that of control group.The BME diagnosis efficiency and optimal water -based concentration of energy spectral CT was analyzed by receiver operating characteristic (ROC)curve.Then,the sensitivity,specificity, positive likelihood ratio and negative likelihood ration were calculated.Results The water -based concentration of BME in research group (1 067.43 ±10.84)g/L was higher than that of control group (1 039.43 ±8.01)g/L(t =-3.14,P =0.003).Meanwhile,the calcium -based concentration of research group (68.98 ±20.53)g/L was not different from control group (78.03 ±26.39)g/L(t =1.88,P =0.066).ROC curve showed that the diagnosis efficiency was medium as the area of under curve was 0.75.When the optimal concentration of water -based was 1 052.00g/L,the diagnosis efficiency was the best.The sensitivity and specificity was 84.00%,62.50% respectively. Conclusion There are reference value and potential clinical value with energy spectral CT water -based concentra-tion detection for diagnosis BME in patients with sacroiliitis.

Objective To evaluate efficacy in detecting lung nodules at low-dose CT(LDCT) by nodule enhanced viewing(NEV).Methods One hundred and twenty seven patients who were referred to undergo low-dose CT (LDCT) for the evaluation of pulmonary metastasis or screening lung cancer were selected randomly.Two radiologists with at least 10 years experience read the images with normal clinical reading speed to find actionable nodules ≤ 2.0 cm in maximum diameter,and their consensus result was referred as Standard.NEV was adopted to detect the pulmonary nodules.Two residents with experience of less than three years read first detected suspicious nodules and recorded reading time,first consensus and mean time were recorded.Then,they made second decisions on the images with the help of NEV and the results and the reading time were recorded and analyzed by using wilcoxon test.The sensitivity and accuracy of NEV,residents and residents with NEV were analyzed.Results Standard,resident,NEV and resident with NEV detected 570,404,768 and 593 lung nodules ≤2.0 cm in maximum diameter,respectively.More than 60％ nodules were less than 0.5 cm in maximum diameter.The performance of NEV in detecting nodules ≤2.0 cm as well as nodules ＜ 0.5 cm in maximum diameter was significantly higher than that of the resident(Z =-6.887,P ＜0.01 and Z =-7.235,P ＜0.01),and the performance of resident with NEV indetecting nodules ≤2.0 cm as well as nodules ＜ 0.5 cm in maximum diameter was significantly higher than that of resident without NEV (Z =-6.606,P ＜ 0.01 and Z =-6.657,P ＜ 0.01).The resident,NEV and the resident with NEV detected nodules ＜ 20 mm in maximum diameter with sensitivities of 61.4％,86.3％ and 95.3％,and with accuracy of 56.1％,58.1％ and 87.6％,respectively.The resident achieved sensitivities of 51.4％,88.1％ and 94.8％,and accuracy of 47.0％,56.9％ and 87.5％ for nodules ＜5 mm in maximum diameter,respectively.The resident,NEV and resident with NEV spent 120-444 s,85-262 s and 131-1512 s per case to read the CT scans,respectively.The reading time of resident with NEV in was significantly higher than that of resident without NEV(Z =-9.781,P ＜ 0.01).The resident spent 23 s per NEV mark.Conclusion NEV considerable improves the resident's performance in lung nodule detection,especially in maximum diameter ＜ 0.5 cm nodule detection.

Objective To evaluate the relationship between the lung volume (LV) in inspiration and expiration,pulmonary function tests(PFT),and other CT measurements of emphysema index (EI) and mean lung density (MLD) in patients with chronic obstructive pulmonary disease (COPD).Methods Seventy-six patients with COPD were included.Three-dimension analysis was performed to obtain the following CT parameters on the inspiratory and expiratory phases:EI,MLD,LV.The ratios and differencesof MLD and LV between the two phases were calculated(ΔMLD,ΔLV,MLDex/in,LVexin).Not only the linear correlations between the lung volume parameters and PFT but also the correlations of lung volume parameters with the other CT parameters were tested by the Spearman rank correlation test and multivariant step wise regression.Results LVex/in had negative correlations with forced expiratory volume in 1 second ％ predicted [FEV1 ％,(54.32 ± 7.11)] and the ratio of forced expiratory volume in 1 second to forced vital capacity [FEV1/FVC,(49.12 ±8.01)％] (r =-0.69,-0.56,P ＜0.01),but it had the positive correlation with the ratio of residual volume to total lung capacity [RV/TLC,(58.03 ± 8.55) ％,Spearman coefficients 0.66,P ＜ 0.01].LV/exin (0.67 ± 0.12) was positively correlated with MLDex/in (0.89 ± 0.04,r =0.88,P ＜0.01).The further multivariate step wise regression denonstrated that EI,LV and MLD could introduce a regression equation with R2 =0.77 and 0.73,respectively (P ＜ 0.01).Conclusions There is an association between LVex/in and the parameters of routine PFT,which can reflect the collapsibility of lung.Moreover,LVex/in can be considered to be equivalent to MLDex/in.Taking into account the impact of scanning parameters on MLDex/in,LVex/in may play a complementary role in the assessment of pulmonary function.

Objective To discuss the application of different types of bronchial arteriography catheter in performing bronchial artery embolization (BAE) for the treatment of hemoptysis.Methods The clinical data of a total of 97 patients with hemoptysis,who received BAE during the period from January 2013 to May 2016,were collected.According to angiographic findings in aspect of the opening and running direction of the arteries causing bleeding,the responsible arteries were divided into 4 types:upward opening,horizontal opening and running upwards,horizontal opening and running downwards,and downward opening.For each responsible artery,appropriate angiography catheter was selected from the following catheters:MIK catheter,left gastric artery catheter,Cobra catheter,Simmon-1 catheter and Simmon-2 catheter.With super-selective catheterization technique the selected suitable catheter was inserted into the responsible artery and angiography was subsequently performed.The effect of the selection of bronchial arteriography catheter in performing BAE for hemoptysis was analyzed.Results A total of 180 responsible arteries were detected in 97 patients.Of the 180 responsible arteries,artery with upward opening was seen in 42,artery with horizontal opening and running upwards was found in 54,artery with horizontal opening and running downwards was observed in 46,and artery with downward opening was detected in 38.The success rates of super-selective catheterization for MIK catheter,left gastric artery catheter,Cobra catheter and Simmon catheter were 83.3％ (35/42),92.6％ (50/54),87.0％ (40/46) and 89.5％ (34/38,including 30 Simmon-1 catheters and 4 Simmon-2 catheters) respectively.After BAE,the responsible arteries were occluded in all patients,and hemoptysis stopped immediately.The recurrence rate at 6 months after BAE was 7.2％ (7/97).Conclusion For the treatment of hemoptysis,BAE is safe and effective.The key point to ensure a successful BAE is that the selection of appropriate catheter should be based on the opening and running direction of the artery causing bleeding.

Objective To observe the degradation time and the intimal hyperplasia of biodegradable magnesium alloy stent (MPM) implanted in the abdominal aorta of experimental rabbits.Methods A total of 24 New Zealand white rabbits were randomly divided into four groups (30 d,60 d,90 d and 180 d) with 6 rabbits in each group.In cach rabbit one MPM stent was implanted in the abdominal aorta at the level of one cm below the left renal artery.Reexamination of abdominal aortography with DSA was separately performed at 30,60,90 and 180 d after stent implantation to check the stent condition.The rabbits of each group were sacrificed at the corresponding scheduled day,the stenting segment of aorta of each rabbit was removed and the specimen was sent for microscopic examination.The experimental results were analyzed with SPSS20.0 software.Results All the 24 experimental rabbits survived.During the follow-up period the stent showed gradual degradation changes,and basically complete degradation was not observed until to 180 days.Meanwhile,the intimal hyperplasia reached its peak at 90 days after implantation.The abdominal aorta remained unobstructed during the whole process of degradation.Conclusion The time of complete degradation for MPM stent is 182 days,which is long enough to meet the needs of vascular positive remodeling.

Objectives: To evaluate the clinical significance of nuclear matrix protein 22 (NMP 22) in the detection of bladder transitional cell carcinoma (BTCC) and compare with voided urine cytology(VUC). Methods: A total of 69 cases with voided urine samples for NMP 22 and VUC test were included in this study. Thirty of them were BTCC patients(BTCC group) and twenty nine suffered from other urological diseases (nonbladder cancer group, NBC group). Ten were healthy volunteers (control group). Results: The NMP 22 values for BTCC group (67.3 U/ml) were significantly higher than that of NBC group(7.4 U/ml) and control group (4.3 U/ml)( P 0.05). NMP 22 was more sensitive than VUC in low grade BTCC(Ⅰ,Ⅱ)(62.50% vs 12.50%,P 0.05). Conclusions:Urinary NMP 22 is a useful marker for the early diagnosis of BTCC. It is more sensitive than VUC in low stage and grade BTCC.
