Objective To detect the presence of DEK protein in the tissue and voided urine of patients with bladder urothelial carcinoma ,and an?alyze the relationship between DEK protein and clinical pathological classification of bladder cancer. Methods The expression of DEK protein was examined by immunohistochemistry in 48 bladder cancer tissues and 18 adjacent normal tissues(control group). The presence of DEK protein in voided urine was analyzed by western blot in 28 bladder cancer patients and 6 healthy individuals(control group). Results The positive ex?pression of DEK protein in bladder tumor tissues(73%)is higher than in adjacent normal tissues(33%,P<0.05). The expression of DEK in su?perficial bladder cancer(86%)was found higher than invasive bladder cancer(55%)with significant differences(P<0.05). The expression of DEK in urine samples of bladder cancer patients(0.834)was found higher than control group(0.242,P<0.05);Compared with the DEK expres?sion of control group,the sensitivity of diagnosis of bladder cancer with voided urine could be 82.1%. Conclusion DEK protein positive ex?pressed in tissues and voided urine of patients with bladder urothelial carcinoma. The expression was correlated with pathological classification of bladder cancer. The positive rate of DEK expression in early stage of tumor tissues is higher than late stage. The presence of DEK protein in tissues and voided urine can be considered as a suitable biomarker for bladder cancer potentially.

Objective To explore the value of spectral imaging technique in dual-energy CT in differential diagnosis of the metastatic lymph nodes in thyroid carcinoma,squamous cell carcinoma metastatic lymph nodes and lymphoma in the neck.Methods In 30 patients with pathologically confirmed with a total of 79 cervical lymph nodes enlargement which were using dual energy scan .Then observed the change trend of the spectrum curve and comparison the three kinds of lymph node energy spectrum curve’s slope.Results In the 79 lymph nodes,the metastatic lymph nodes in thyroid carcinoma were twenty-three,squamous cell carcinoma metastatic lymph nodes were twenty-four and lymphoma were thirty-two.From 60 to 180 keV,with the increase of keV values,the three kinds of malignant lymph nodes of the corresponding CT value decreasing and the higher the keV value,the CT value decrease magnitude was small,and the spectrum curve was〞drop type〞.The slope spectrum curve of the metastatic lymph nodes of thyroid carcinoma in arterial phase and parenchymal phase were maximum,which were 1.23±0.41 and 0.85±0.33,respectively.The slope spectrum curve of lymphoma in arterial phase and parenchymal phase were least,whcih were 0.40±0.16 and 0.47 ±0.09.The slope spectrum curve of the squamous cell carcinoma metastatic lymph nodes in arterial phase and parenchymal phase were 0.88±0.10 and 0.62±0.28.The energy spectrum curve slope of the three kinds of malignant lymph nodes have statistical significance.Conclusion The energy spectrum curve slope of arterial phase and parenchymal phase has some significance lymph node metastasis of in thyroid carcinoma,the metastatic lymph nodes and lymphoma in the neck.

Objective To establish a finite element model of rotator cuff which can be used to simulate the rotator cuff injury and to evaluate the biomechanical effects of rotator cuff surgery.Methods The Dicom CT images of the right shoulder of a Chinese healthy volunteer were used to establish models of the scapula,humerus and clavicle.The rotator cuff structures were separated and modeled based on the MRI images and anatomical knowledge.After the rotator cuff model was introduced into the finite element analysis software Abaqus 6.12,the anatomical positions were simulated when the shoulder was at 30° internal rotation,30° external rotation,30° abduction,30° adduction,30° flexion and 30° extension.Results When the shoulder was in 30° flexion,the average stress was 52.2 kPa on the supraspinatus,223.0 kPa on the inffaspinatus and the teres minor,and 90.4 kPa on the subscapularis.When the shoulder was in 30° extension,the average stress was 105.0 kPa on the supraspinatus,78.2 kPa on the infraspinatus and the teres minor,and 55.7 kPa on the subscapularis,indicating that the muscle and tendon of the supraspinatus was subjected to greater stress and the humerus and the scapula produced less stress compared with the shoulder in 30° flexion.Conclusion Since our finite element model of the rotator cuff can simulate common activities of the shoulder joint and obtain stress values of the corresponding rotator cuff muscles,it can be used in simulation of rotator cuff injury and its surgery.

Objective Study the apply of diffusional kurtosis imaging(DKI) value to assess liver cancer and tumoral cell invasion of peritumoral liver zone. Methods This research belonging to prospective study which included 24 patients with liver cancer and confirmed by clinical history and imaging features(liver cancer group), 10 healthy volunteers as control group. The liver cancer group underwent MRI plain and contrast enhanced scan, and DKI examination, while control group underwent MRI plain scan and DKI scan. The signal features of liver parenchyma and liver cancer lesion could be observed from the routine MRI and DKI. Fractional anisotropy (FA), mean diffusion (MD), axial diffusivity (Da), radial diffusivity (Dr), fractional anisotropy kurtosis (Fak), mean kurtosis (MK), kurtosis anisotropy (Ka) and radial kurtosis (Kr) value of four groups, the distant liver parenchyma(far away from the tumor>2 cm), peritumoral liver parenchyma(the distance≤2 cm around the tumor) and liver cancer were recorded. The differences of DKI parameters were evaluated using one-way analysis of variance (ANOVA). Results The signal of liver cancer in MR plain scan showed mild long T1 and mild long T2 signal, fast in and fast out enhanced feature of the neoplasms could be observed from the enhanced MRI and signal of liver cancer would not lower in DKI with b value up to top. The difference of DKI parameters including FA, MD, Da, Dr and Ka value had statistical significance in these four groups excepted for MK and Kr value. MD, Da and Dr value of normal parenchyma were higher than that of peritumoral parenchyma and liver cancer,while the Ka value was reverse. The differences of MD, Da, Dr and Ka value only had no statistical significance between the distant liver parenchyma and peritumoral liver parenchyma(P>0.05),and the differences of them had statistical significance among the rest group(P<0.05). Conclusion The DKI quantitative parameters can reflect the differences of different tissue, meaning that they can provide molecular imaging information for evaluating liver cancer and peritumoral zone.

Objective To observe the effect of Yingliu mixture combined with methimazole on autoantibodies and traditional Chinese medical syndromes of patients with Graves’ disease ( GD) . Methods A randomized, paralleled and controlled trial was carried out in 92 GD patients. The patients were evenly randomized into treatment group and control group, and were separately treated with Yingliu mixture combined with methimazole, and methimazole. The treatment for both groups lasted 12 weeks, and forty patients in each group completed the whole treatment. The changes of thyroid function, thyroid autoantibodies, and traditional Chinese medical syndrome scores were observed before and after treatment, and the clinical efficacy was also evaluated. Results (1) After treatment for 12 weeks, serum levels of thyroid peroxidase antibody (TPOAb), thyroglobulin antibody ( TGAb) and thyrotrophin receptor antibody ( TRAb) were decreased, and thyroid stimulating hormone ( TSH) was increased obviously in both groups after treatment ( P<0.01 compared with those before treatment) . The treatment group has better effect on improving TGAb and TRAb than the control group ( P<0.05). ( 2) Compared with those before treatment, the total scores of clinical symptoms and signs were decreased in the two groups at different time points of treatment course ( P<0.001) , and the decrease value in the treatment group was larger than that in the control group ( P<0.05) . ( 3) The total effective rate of the treatment group was 92.50%, higher than 82.50% of the control group ( P<0.05) . Conclusion Yingliu mixture combined with methimazole is effective on improving thyroid function, decreasing autoantibodies levels and relieving clinical symptoms and signs, and has better effect than methimazole alone for the treatment of GD.

Objective To investigate the protective effects of Trimetazidine(TMZ)on the ischemia reperfusion injury (IRI)of fatty liver in autotransplantation model. Methods Fatty liver model was established by feeding high fat diet. Male Wistar rats (n=30) were randomized into three groups;Sham group, TMZ group and Model group. Liver was autotransplanted in both TMZ group and Model group. Serum levels of ALT, SOD, MDA, Bcl-2 and activated Caspase-3 were assessed 6 hours after the operation. The pathological performances of liver were also determined. Results Compared with the Model group, serum levels of ALT,AST, MDA and SOD levels decreased significantly in the TMZ group(P<0.05). Serum level of Bcl-2 was higher while level of activated Caspase-3 was lower in TMZ group than those in Model group(P<0.05). Histo?logical assay and TUNEL staining showed reduced hepatocyte swelling and narrowed sinusoid as well as decreased hepatic apoptosis in TMZ group compared with Model group. Conclusion TMZ can reduce oxidative stress, promote the expression of Bcl-2 and inhibit the activation of Caspase-3, which all contribute to its protective effect on fatty liver with ischemia-re?perfusion injury.

Objective:To analyze the role of preoperative circulating tumor cell(CTC) and circulating tumor vascular endothelial cells (CTEC) in the diagnosis of gastric cancer and its correlation with the clinicopathological characteristics of gastric cancer.Methods:Sixty-two gastric cancer patients and 11 patients of benign gastric diseases were enrolled. Subtraction enrichment (SE) and immunofluorescence staining-chromosome fluorescence in situ hybridization (i·FISH) were used to integrate the unique SE-i ·FISH technology platform detecting patients′ CTC and CTEC.Results:The number of CTC in the gastric cancer group was significantly higher than that in the control group ( t=2.693, P=0.009); the number of CTEC in the gastric cancer group was higher than the control group ( t=2.015, P=0.048). With the cut-off value being set at 9 cells/6 ml in blood, the sensitivity of CTC in the diagnosis of gastric cancer is 84%, and the specificity is 82% (AUC=0.876, 95% CI, 0.792-0.963, P<0.01); When set at 6 cells/6 ml, the sensitivity of CTEC in the diagnosis of gastric cancer is 50%, and the specificity is 100%(AUC=0.727, 95% CI, 0.603-0.851, P=0.02). CTC positive is closely related to tumor location(χ 2=4.292, P=0.038 ) and TNM stage(CTC≥10, χ 2=4.848, P=0.028; CTC≥11, χ 2=6.234, P=0.013). CTEC positive is closely related to serum CA19-9(χ 2=4.858, P=0.028) and serum CA724 (χ 2=4.108, P=0.043 ) . Conclusion:SE-i·FISH technology has high sensitivity and specificity in the detection of CTC and CTEC of gastric cancer.

Objetive The present study was aimed to explore the risk factors of mid-term cognitive decline in pa?tients with indexed TIA/minor stroke (NIHSS≤3) in a Chinese hospital-based cohort. Methods We recruited all consec?utive Chinese TIA/minor stroke patients from July to December in 2012 and followed them up in stroke clinics at 3 and 18 months after indexed TIA/minor stroke. The outcome was defined as significantly cognitive decline at 18 months com?pared with that at 3 months. Results A total of 209 consecutive Chinese TIA/minor stroke cases completed their fol?low-up investigation. Among them, 24 (11.5%) exhibited significantly cognitive decline. The independent risk factors of cognitive decline post TIA/minor stroke were education years (OR=0.869,P=0.021), atrial fibrillation(OR=5.950, P=0.001) and multiple silent lacunar infarcts (OR=5.179,P=0.020). Conclusion It is necessary to evaluate the cognition among TIA/minor stroke cases and a close follow-up is required for patients with atrial fibrillation and multiple silent la?cunar infarcts frequently in order to decrease the risk of cognitive decline post TIA/minor stroke.
