AIM: To study the effects of resveratrol on the proliferation of human retinal vascular endothelial cells induced by cobalt chloride-simulated hypoxia in vitro.METHODS: CoCl2 (100μmol/L) was used to simulate hypoxic condition, and human retinal vascular endothelial cells were cultured in vitro as model. The cell proliferation was determined by MTT method; SABC method was employed to test the expression of vascular endothelial growth factor (VEGF); and computer image analyzer was used to process data. The effects of resveratrol on the proliferation of vascular endothelial cells were observed.RESULTS: Resveratrol inhibited the proliferation of human retinal vascular endothelial cells induced by CoCl2 in a dose- and time-dependent manner in vitro, meanwhile VEGF expression in all groups which were administered medicine was down-regulated. Both kinds of inhibitive effects of resveratrol were statistically significant (P<0.01).CONCLUSION: Resveratrol can significantly inhibit the proliferation of human retinal vascular endothelial cells and the expression of VEGF, which may provide a new approach for prevention and treatment of retinal neovascular diseases.

Objective To investigate the application value of MR rthrography (MRA) in the diagnosis of acetabular labral tears. Methods Fifteen patients with a high degree of suspected acetabular labral tears received fluoroscope-guided injection of the contrast media into the hip joint ( hip arthrography) and fat-saturated spin-echo T1-weighted images were obtained in the coronal, sagittal, oblique-axial and radial planes. Hip arthroscopy was performed on 12 of them. Results Labral tears which were diagnosed in 11 patients by hip MRA were confirmed at hip arthroscopy. One patient showed no MRA indication of labral tear, also showed normal on arthroscopy. Tear in the anterior-superior quadrant 10 cases of 12 joints ( 12/13), posterior-superior quadrant 1 case of a joint (1/13). In 11 patients who underwent arthroscopy, hip MRA diagnosed 3 (3/13) joints labral tears in coronal planes, 10 (10/13) joints in sagittal planes and 13 (13/13) labral tears in axial-oblique and radial planes. In 15 patients with 20 hip joints, 5 cases 6 joints (6/20) with normal acetabular sublabral sulcus were performed. Conclusions MR arthrography of hip is a reliable method in the diagnosis of acetabular labral tears. Scanning method should be included fat-saturated spin-echo T1-weighted images in sagittal and oblique-axial planes or sagittal plus radial planes. The diagnosis of tor posterior-inferior quadrant should pay attention to the existence of a normal variation.

ObjectiveTo investigate the roles of 11 β-hydroxysteroid dehydrogenase type 1 ( 11 β-HSD1 )on hippocampus of rat with chronic unpredictable mild stress (CUMS).MethodsTwenty-four male SpragueDawley rats were randomly divided into control group and depressive model group. Chronic unpredictable mild stress (CUMS) was used to make up depressive animal model.Behavioral changes were recorded by body weight measuring,sucrose consumption test (SCT) and open field test (OFT),respectively.The mRNA transcription of 11β-HSD1 in hippocampus tissues of the rats were detected by real-time RT-PCR,and the protein expression of 11β-HSD1 were detected by western blot and immunofluorescence.ResultsBcforc starting CUMS protocol,the rats exhibited equivalent weight and sucrose consumption.Twenty-eight days after CUMS protocol,behavior parameters such as body weight,sucrose consumption,nunber of crossing,and number of rearing were significantly decreased in rats exposed to CUMS group compared with control group (P ＜ 0.05,P ＜ 0.01 ).Correspondingly,realtime RT-PCR assays showed the mRNA expression of 11 β-HSD1 in the hippocampus of CUMS group,which was (31 ±9) ％ lower than that of control group.Meanwhile,the protein expression of it in CUMS group was lower than that of control group (P ＜ 0.05 ).Inmunofluorescence revealed that the number of positive 11 3-HSD1 cells was high (223 ± 13) in the control group,while the number was decreased prominently (92 ± 11 ) in the CUMS group (P ＜ 0.01 ).ConclusionDepressive behavior of rats is induced and the expression of 11 β-HSD1 in the hippocampus is decreased prominently by CUMS,the mechanism of which is at least related to the low expression of 11β-HSD1 and disturbance of glucocorticoid metabolism caused by CUMS.

Objective To evaluate the diagnostic value of quantitative analysis parameters of dynamic contrast-enhanced magnetic resonance imaging (MRI) in differential diagnosis of prostatic disease.Methods 12 patients with prostate cancer and 16 patients with benign disease underwent DCE-MRI examination.Region of interest (ROI) were drawn in areas of cancerous foci,normal prostate peripheral zone and normal prostate central gland to measure the values of Ktrans (transport constant),Kep (rate constant),Ve (extravascular extracellular volume fraction).Values of the three parameters were analyzed by ANOVA and the differences were compared between the different tissues.Results The values of Ktrans,Kep and Ve were (0.42±0.10)/min,(0.64±0.11)/min,(0.61±0.14) respectively in the area of cancerous foci,while (0.17 ±0.08)/min,(0.32 ±0.10)/min,(0.59±0.11) respectively in normal prostate peripheral zone,and (0.33±0.12)/min,(0.50± 0.16)/min,(0.62 ±0.07) respectively in normal prostate central gland.The differences in Ktrans,Kep values were statistically significant between cancerous foci,normal prostate peripheral zone and normal prostate central gland (F =31.646,27.196,respectively,all P ＜ 0.05),but no statistically significant difference was found in the Ve value between the three different tissues (F=0.533,P＞ 0.05).Conclusions Quantitative analysis of DCE-MBI can be used to differentiate benign from malignant prostatic diseases,which hasa great application prospect.

Objective To explore the magnetic resonance spectroscopy characteristics of prefrontal white matter in bipolar Ⅱ disorder and its relation with executive function.Methods Thirty bipolar Ⅱ disorder patients and twenty healthy controls were evaluated with Multi-Voxel proton magnetic resonance spectroscopy (1H-MRS)scans on prefrontal white matter to assess the N-acetyl-aspartate (NAA),Choline (Cho),Creatine (Cr) and myoinositol (MI),and then the ratios of NAA/Cr,Cho/Cr,MI/Cr,NAA/Cho and NAA/Cho + Cr were calculated.All subjects were assessed for executive function using the Wisconsin Card Sorting Test (WCST).Results NAA/Cr in right prefrontal white matter(1.43 ± 0.26) and NAA/Cr,NAA/Cho,NAA/Cho + Cr in left prefrontal white matter (separatelyl.40 ± 0.29,1.13 (1.53,0.24),0.62 ± 0.12) were lower than healthy controls (separately 1.58 ±0.18,1.59,0.23,1.30 (0.53 ± 0.29),0.71 ± 0.08) (P ＜ 0.05).The correct trials and the number of categories of WCST in Bipolar Ⅱ disorder (separately 26.97 ± 8.97,3(6,3)) were less than in healthy controls(separately 36.35±4.85,5 (3,2)),and perseverative errors and random errors were more in patients (separately 12.77 ±5.73,7 (21,5)) than healthy controls (separately 7.35 ± 3.01,4 (13,2)).NAA/Cho and NAA/Cho + Cr in left prefrontal white matter were positively correlated with correct trials,number of categories,and negatively related with perseverative errors (P＜0.05).Conclusions Bilateral prefrontal white matter fiber damage occurs to bipolar Ⅱ disorder.And left prefrontal white matter fiber damage in bipolar Ⅱ disorder may lead to executive impairment.

Objective To investigate the cause and related factors of hospitalization in patients with diabetic nephropathy with maintenance hemodialysis.Methods Fifty-six patients of diabetic nephropathy were enrolled in current study who hospitalized in Beijing Tongren Hospital affiliated to Capital Medical University from March 2009 to February 2012.All subjects were divided into hospitalized group (n =29) and non hospitalized group (n =27).The information including age,dialysis age,blood pressure,hemoglobin,blood glucose,serum creatinine,serum potassium,plasma albumin,serum calcium,serum phosphorus,albumin,intact parathyroid hormone (iPTH) and hemodialysis sufficienc (KT/V) were collected.Stepwise multiple regression analysis was applied to explore the main causes and related risk factor.Results Twenty-nine out of 56 patients were hospitalized and they had 56 hospitalization records during 24 months of observed period.Average hospitalization was 1.0 times per patient and hospitalized days were (29.62 ± 14.30) days per hospitalized patients.The main causes of hospitalization were cardiac vascular diseases (35.7％),vascular access stenosis (30.4％),and pulmonary infection (17.8％).Compare with non-hospitalization group,age of patient hospitalization group was older((66.97 ± 9.94) vs.(57.42 ± 11.77),t =2.917,P =0.02) and the level of albumin and Kt/V were lower(albumin:(34.02 ± 4.76) vs.(38.93 ± 3.82),t =-4.573,P =0.000 ; Kt/V:(1.16 ± 0.09) vs.(1.39 ± 0.18),t =6.503,P =0.000).Stepwise multivariate regression analysis showed plasma albumin and KT/V were risk factors to influence the hospitalization in diabetic patients undergoing maintenance hemodialysis (β =-1.724,-0.040 respectively,P =0.00,0.02 respectively) Conclusion Cardiovascular disease,vascular access stenosis and pulmonary infection were the important factors for hospitalization in hemodialysis patients with diabetic mellitus.Cardiovascular disease was the top reason of hospitalization in diabetic patients with maintenance hemodialysis.Hypoalbuminia and inadequacy dialysis were risk factors to influence the hospitalization in diabetic patients undergoing maintenance hemodialysis.

Objective To explore the correlation between high-risk human papillomavirus(hr-HPV) viral load and severity of cervical lesion. Methods One thousand eight hundred and six women undergoing both hr-HPV DNA test by hybrid capture Ⅱ(HCⅡ) and colposcopic biopsy for histologic results were enrolled in this study.Correlation between hr-HPV viral load and pathological findings was investigated. Results Of 1 806 cases,641(35.5%) patients were positive for HPV DNA.23.2%(301/1299) of women with normal diagnosis had HPV infection,significantly lower than cervical lesion including cervical intraepithelial neoplasia(CIN) and cervical cancer(P=0.000).Associations(odds ratio) among severity of cervical lesion and viral load were calculated.The significantly increased risk only existed between cervical cancer and CIN1 on high viral load(odds ratio,8.5;95% confidence interval,1.0-71.4;P=0.049).Furthermore,viral load values in CIN1,2,3 and cervical cancer were calculated and median analysis revealed non-significant difference(P=0.712). Conclusion The hr-HPV viral load can distinguish cervical lesion as CIN and cervical cancer from normal one,while the prediction of the severity of cervical lesion may be inadequate and need further investigations.
