The effects of fenofibrate on plasminogen activator inhibitor-1 (PAI-1) expression in human umbilical endothelial cell-derived transformed cell line--ECV 304 cells were investigated. ECV 304 cells were incubated with different concentrations of fenofibrate (0, 10, 50, 100 micromol/L) for 24 h. PAI-1 mRNA and protein was detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot respectively. PAI-1 antigenic content of endothelial cells was measured by using ELISA. Fenofibrate could inhibit the PAI-1 mRNA and protein expression and reduce PAI-1 antigenic content dependently. After treatment with fenofibrate (10 micromol/L), the expression levels of PAI-1 mRNA and protein were 0.65 +/- 0.05 and 0.96 +/- 0.11 respectively, significantly lower than in the control group (0.78 +/- 0.03 and 1.21 +/- 0.15, respectively, P<0.05). PAI-1 antigenic contents (24.52 +/- 8.39) in ECV304 cells treated with 10 micromol/L fenofibrate were significantly lower than those in the control group (6.98 +/- 5.12, P<0.05). It was concluded that fenofibrate inhibited the expression of PAI-1 mRNA in ECV304 cells, and reduce the protein expression and the antigenic content of PAI-1, suggesting that fenofibrate may have an antiatherosclerotic effect on endothelial cells by PAI-1 pathway.

Objective To analyze and compare the imaging characteristics of contrast-enhanced ultrasound (CEUS) and contrast enhanced magnetic resonance imaging (CEMRI) in diagnosing hepatic epithelioid hemangioendothelioma (HEHE) for improving radiological diagnostic accuracy.Methods The imaging characteristics of CEUS and dynamic CEMRI in 17 patients with histopathological diagnosis of HEHE on specimens obtained after surgical resection or fine needle biopsy were retrospectively analyzed and compared.Results On CEUS,20 lesions in 13 patients demonstrated different enhancement patterns in the arterial phase:13 lesions (65.0％) displayed gross enhancement and 7 lesions (35.0％) displayed a rimlike enhancement.Synchronous enhancement was observed in 17 lesions (85.0％) and rapid enhancement was observed in 3 lesions (15.0％).All these 20 lesions manifested as a hypoechoic mass in the portal venous and delayed phases.Other characteristics included speculated enhancement in the inner margin of the lesions and a vessel sign.On CEMRI,45 lesions (71.4％) manifested slight enhancement in the arterial phase and continuous enhancement in the portal venous and delayed phases.The remaining 18 lesions (28.6％) manifested no enhancement in the arterial phase but progressive enhancement in the portal venous and delayed phases.47 lesions (74.6％) displayed a rim-like enhancement and 16 lesions (25.4％) displayed gross enhancement.Other imaging characteristics included a halo sign,a lollipop sign,a capsular retraction sign or avessel sign.Conclusions On CEUS,characteristic manifestations of HEHE were synchronous enhancement with a quick wash-out.At peak time,the enhancement degree was equal to the normal liver parenchyma.On CEMRI,the main radiological feature of HEHE was a rim-like enhancement.In the arterial phase,the enhancement degree was not high and there was either a continuous enhancement or a progressive enhancement in the portal venous and delayed phases.Furthermore,HEHE lesions always occurred under the liver capsule and showed acapsular retraction sign,ahalo sign,a lollipop sign or a vessel sign.The combination of CEUS and CEMRI helped to improve the diagnostic rate and contributed to selection of clinical treatment.

Purpose To analyze and compare the imaging characteristics of contrastenhanced ultrasound (CEUS) and dynamic contrast-enhanced CT for hepatic epithelioid hemangioendothelioma (HEHE) diagnosis.Materials and Methods The imaging characteristics of CEUS and dynamic contrast-enhanced CT performed on 16 patients with pathological-confirmed HEHE were retrospectively analyzed.Dynamic contrast-enhanced CT was performed on 5 patients,real-time CEUS was performed on 8 patients,and both examinations were performed on 3 patients.Results On CEUS,14 lesions were selected from 11 HEHE cases.In the case of enhancement mode,5 lesions displayed ringenhancement,and 9 lesions displayed global enhancement;in the case of arterial phase,11 lesions were synchronously enhanced,and 3 lesions were rapidly enhanced compared with liver parenchyma;in the case of peak time,hyper-enhancement,iso-enhancement and hypo-enhancement were observed in 2 lesions,9 lesions and 3 lesions,respectively;all 14 lesions manifested hypoechoic mass in portal phase and delayed phase.On dynamic contrast-enhanced CT,29 lesions were found in 8 HEHE cases.In the case of arterial phase,9 lesions (31.0％) showed slight inhomogeneous enhancement,4 lesions (13.8％) showed no obvious enhancement and 16 (55.2％) lesions showed slight edge enhancement;all 29 lesions presented continuous hypo-enhancement in delayed phase.Conclusion Both CEUS and dynamic contrast-enhanced CT have respective characteristic manifestations,and are of high value for the diagnosis of HEHE.

Objective To investigate JC virus(JCV) infection in kidney transplant recipients and its influence on graft function and also initially explore JCV infection factors. Methods A total of 49 kidney transplant recipients and 24 health examination persons were enrolled in our study, JCV DNA was measured using nested qualitative polymerase chain reaction assays of urine, while CMV DNA was measured by common qualitative polymerase chain reaction assays of urine. JCV infection factors, such as age, male, immunosuppressive therapy, cytomegalovirus(CMV) infection were analyzed by Binary Logistic Regression, and glomerular filtration rate(GFR) was selected as a index of kidney function and the difference of GFR between JCV-infected and non-infected patients was compared using t test. Results JCV was detected in 42.9% of kidney transplant patients and 4.2% health examination persons. CMV infection and Pred + MMF + CsA triple immunosuppressive regimen were found to be the risk factors of JCV infection. No difference of GFR was observed between JCV infected and non-infected patients (86.470 ± 29.990 and 84.060 ± 33. 729 for each; t =0. 259, P =0.797). Conclusion JCV is frequently detected in kidney transplant recipients. CMV infection and using of Pred + MMF + CsA triple immunosuppressive regimen can significantly increase the risk of JCV infection. While, graft function was not influenced by JCV infection in kidney transplant patients.

Objective To investigate the common initial clinical presentations of primary Sj(o)gren's syndrome (pSS) with pulmonary complications,and to explore the differences between patients with extraglandular manifestations at disease onset (EGM) and those with glandular manifestations at disease onset (GM).Methods A total of 1 341 hospitalized SS patients from 2003 to 2012 were retrospectively reviewed.Of them,102 hospitalized patients with pSS'associated lung disease were analyzed and included.Case control study was performed to explore the differences between the EGM group and the GM group.Results Fifty-one percent of patients were presented with EGM at onset,with significantly shorter disease duration [36 (12,156) m vs 102 (48,159) m,x2=-2.41,P=0.016].Although the mean diagnose time was similiar,only 4％ of the EGM group could be confirmed the pSS diagnose at onset,which was significantly less frequently than that of the GM group (34％,22=15.29,P＜0.01).Case control study revealed that hyperglobulinemia,elevated RF titers and anti-SSA and/or anti-SSB test positive were less predominant in the EGM group [IgG 16(12,21) g/L vs 21 (15,28) g/L,x2=-2.15,P=0.032;22 (20,171) U/ml vs 104 (20,238) U/ml,x2=-l.98,P=0.048;33％ vs 72％,x2=15.78,P＜0.01].The predicted value of TLC and FVC were lower [(87±23)％ vs (97±20)％,x2=-1.96,P=0.050;(8±28)％ vs (100±27)％,x2=-1.70,P=0.089] and HRCT score was higher in EMG group [12(88,15) vs 8(5,13),x2=-1.82,P=0.070].Conclusion EMG at onset is the common initial manifestation of pSS'associated lung involvement.Pulmonary complication is more progressively and severe than those with MG at onset.Anti'SSA positive,elevated RF titer and hyperglobulinemia are not predominant for patients with EMG at onset.

Objective:To explore the clinical utility of tongue pressure resistance feedback training in the treatment of post-stroke dysphagia.Methods:Twenty stroke survivors with dysphagia were randomly divided into an experimental group and a control group. Both groups were given conventional swallowing rehabilitation training, while the experimental group was additionally provided with tongue pressure resistance feedback training. Before and after the treatment, MBSImp analysis and the Rosenbek penetration aspiration scale were used to quantify the control of the tongue, food delivery, oral residue, laryngeal elevation, hyoid bone movement, epiglottis turnover, larynx closure, vestibular larynx closure, pharyngal peristalsis and contraction, opening of the upper esophageal sphincter UES, contraction of the base of the tongue, pharyngeal residue and aspiration.Results:No significant differences were observed between the two groups before the intervention. Afterward the average pharyngeal period and aspiration score of the experimental group had decreased significantly compared with the control group′s values.Conclusions:Tongue pressure resistance feedback training is effective in improving pharyngeal swallowing and reducing the risk of aspiration after swallowing.

In order to explore the molecular mechanism of arsenic trioxide treating multiple myeloma (MM) via inhibition of angiogenesis, the expression of brain derived neurotrophic factor (BD-NF) and its specific receptor TrkB in human MM cell line KM3 and endothelial cell line ECV304 was detected by Western blotting. The angiogenic activity was evaluated by wound migration assay and tubule formation assay in vitro. The results showed that BDNF was detected in the MM cells and TrkB in the endothelial cells. Furthermore, 100 ng/mL BDNF could significantly induced endo thelial cell tubule formation and wound migration. As2 O3 depressed the expression of BDNF and TrkB in the dose- and time-dependent manner. As2O3 inhibited BDNF-induced wound migration and capillary tube formation. It was concluded that BDNF is a novel angiogenic protein as well as VEGF and has a relation with the pathogenesis of MM. As2O3 interrupts a paracrine loop between MM cells and endothelial cells by down-regulating the TrkB expression in endothelial cells and inhibiting BDNF production in MM cells, finally resulting in inhibition of MM angiogenesis. This is probably one part of the mechanisms of the As2O3 treating MM via the inhibition of angiogenesis.
