Objective To investigate the senescence of rat mesangial cells induced by Tert-Butyl hydroperoxide (tBHP) and the protective effect of probucol on senesecence. Methods Human glomerular mesangial cells(hGMC) were cultured in vitro and intervened by tBHP. The cell survival rate was observed by methyl thiazolyl tetrazolium( MTT). β-gal staining and cell cycle analysis were used to identify cell senescent status;transmission eletric microscopy was used to evaluate the ultra-microstructure of hGMC. Senescent-related indexes were detected after treatment with probucol. Results The cell survival rate with 30 μmol/L tBHP was (80. 12 ± 3. 25 ) % , the positive rate of β-gal staining was significantly higher in tBHP-induced cells (about 81% )than that of the control cells( P <0. 01). 86% of the cells was arrested at G0-G1 phase. Invagination of nucleus membrane and chromatin condensation at the nuclear margin in tBHP-induced cells was observed through transmission eletric microscopy. In the probucol intervented cells, the cell survival rate was higher than that of tBHP-induced cells (92. 68 ± 5.03) % vs. ( 80. 12 ± 3. 25) % (P < 0. 05 ). The positive rate of β-gal staining decreased to 45. 2%. The proportion of cell cycle stage was similar to the control cells.The change of morphous and ultrastructure was relieved. Conclusions tBHP can induce hGMC senescence in vitro and probucol may play a role in preventing hGMC senescence.

Objective To evaluate the clinical value of high-resolution ultrasound for predicting the extracapsular extension (ETE) of papillary thyroid cancer (PTC).Methods A total of 151 nodules with PTC in 116 patients confirmed by surgery and pathology were enrolled.The ultrasonographic characteristics were retrospectively analyzed,and the percentage of the perimeter of the nodule that abutted the thyroid capsule (A) were observed.Taking A≥1％,A≥25 ％ and A≥ 50％ as cutoff value respectively,the ETE of PTC was predicted.Results Of the 151 nodules with PTC,ETE presented in 59 (59/151,39.07％),while no ETE (non-ETE) was observed in 92 (92/151,60.93％).Nodules in the thyroid parenchyma (A0) which could be observed with ultrasound was 84 (84/151,55.63％),and 1％≤A＜25％,25％≤A＜50％andA≥50％ was 25 (25/151,16.56％),15 (15/151,9.93％),and 27 (27/151,17.88％),respectively.There were statistically significant differences of nodules between the non-ETE and ETE when A≥1％,A≥25 ％ and A≥50％ (all P ＜0.01).Taking A=50％ as the cutoff value for predicting the presence of ETE,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value was 37.29％ (22/59),94.57％ (87/92),72.19％ (109/151),81.48％ (22/27) and 70.16％ (87/124),respectively.Conclusion High frequency ultrasonography can effectively predict whether PTC has been invaded,which provides important reference information for preselected surgical approach and prognosis of patients.

Objective To screen potential serum HCC associated proteins with low molecular weight and low abundance for better understanding the pathological mechanism of HCC and discovering new biomarkers.Methods All serum samples were collected from 81 HBV-related HCC patients,43 chronic hepatitis B patients and 36 cirrhosis patients.Serum protein fingerprint profiles were first generated by selected WCX2 protein chip integrating with SELDI-TOF-MS,and then normalized and aligned by Ciphergen SELDI Software 3.1.1 with Biomarker Wizard.Comparative analysis of the intensity of corresponding protein fingerprint peaks in normalized protein spectra was performed.Some protein peaks with significant difference among HCC,cirrhosis and chronic hepatitis B groups were found.The reproducibility of the SELDI system was assessed before serum protein fingerprint profiles analysis.Results The intra-and inter-assay CV for intensity and m/z in this SELDI system were 17.46% and 0.024%,and 17.74% and 0.024% respectively.Total 128 protein fingerprint peaks between 2 000 to 30 000 Da were identified under the condition of signal to noise＞5 and minimum threshold for cluster＞20%.Eighty-seven proteins were found to significantly expressed between HCC and cirrhosis groups(P＜0.05).Of the above differential proteins,forty-five proteins had changes greater than two fold,including 15 up-regulated proteins and 30 downregulated proteins in HCC sera.Between HCC and chronic hepatitis B groups,nine of fifty-two differential proteins(P＜0.05) had intensities of more than two folds,including 2 up-regulated proteins and 7 downregulated proteins in HCC sera.Between cirrhosis and chronic hepatitis B groups,twenty-eight of seventynine significantly differential proteins(P＜0.05) changed greater than two folds in intensity,including 17 up-regulated proteins in cirrhosis seru and 11 down-regulated proteins in chronic hepatitis B sera.Analysis of above leading differential proteins among three diseases using subtraction difference mode,the 5 common down-regulated proteins 2 870,3 941,2 688,3 165 and 5 483 m/z in HCC sera and 2 common up-regulated proteins 3 588 and 2 017 m/z in cirrhosis and HCC sera were screened.But no statistic difference in the level of protein 2 017m/z was found between HCC group and normal group inour previous study.Conclusion Because the interference of unspecific proteins from hepatitis B and cirrhosis could be eliminated partly in HCC sera through subtraction difference analysis,these 6 common differential proteins (2 870,3 941,2 688,3 165,5 483,3 588 m/z)have obvious advantages of increased specificity for evaluating the pathological state of HCC and might become promising candidate biomarkers in the diagnosis of HCC.

ObjectiveTo investigate the status and explore methods to improve the quality of diabetic education for young and middle-aged patients.MethodsOutpatients took part in diabetic education program and young and middle-aged diabetic patients that visited the eastern district of affiliated hospital of Qingdao university medical college from May 1st,2010 to Oct.30th,2010 were investigated with questionnaire for their diabetic education status and demands.ResultsA total of 381 patients were enrolled in this study.59.1％ clinical diabetic education program participants were aged 60 or older and only 40.9％ were aged 20 to 59 years,of whom 66.7％ had been diagnosed with diabetes more than 5 years and only 33.3％ had been diagnosed with diabetes less than 5 years.According to the survey of 101 young and middle-aged diabetic patients,only 16.8％ patients younger than 60 took part in different kinds of diabetic education programs but about 95％ young and middle aged patients wished to participate in diabetic education programs.ConclusionYoung and middle-aged diabetic patients have received much less diabetic education than elderly patients.Diabetic education for young and middle-aged patients needs to be strengthened urgently.

Objective To investigate the incidence, imaging and clinical characteristics in elderly patients with coronary artery ectasia (CAE). Methods A retrospective analysis was conducted on patients with CAE who underwent coronary angiography between January 2006 and December 2012. According to age, the enrolled patients were divided into two groups (elderly group, age≥ 65 years; non-elderly group, age < 65 years). The clinical feature, imaging characteristics and the 5-year survival rate of the two groups were compared.Results The preva-lence of CAE in elderly patients was 0.33%. Patients in elderly group were found to have significantly higher proportion of female (30.1%vs. 10.1%,P< 0.001), three-vessel disease (60.5%vs. 45.2%,P = 0.003) and localized ectasia (55.0%vs. 40.2%,P = 0.003). In addition, body mass index (20.90 ± 2.71 kg/m2vs. 22.31 ± 2.98 kg/m2,P < 0.001) and percentage of current smokers (45.0%vs. 64.6%,P < 0.001) were significantly lower in elderly group. Cumulative survival curves demonstrated reduced 5-year cumulative survival at the follow-up in the elderly group compared with the non-elderly group (88.0%vs. 96.0%,P = 0.002). But the 5-year event free survival rate failed to show a significant difference between the two groups (31.0%vs. 35.0%,P= 0.311).ConclusionThe prevalence of CAE in elderly patients was 0.33%, which was about 1/3 of the entire numbers of CAE patients. There were significant differences between the elderly and the non-elderly patients with CAE in terms of coronary artery disease risk factors and coronary artery ectatic characteristics. CAE might be asso-ciated with increased mortality risk in the elderly.

Objective To construct the recombinant expression vector encoding antisense Tcf fragment for the blockage of abnormal Wnt pathway, and to investigate its effect on the biological behaviors of human hepatocarcinoma cells. Methods Antisense expression vector was transfected into hepatocarcinoma cells SMMC-7721 with GeneJammer. RT-PCR and Western blot were used to detect Tcf expression. Cell proliferation and motility were compared by growth curves and Transwell plate assay. Cell apoptosis was determined by Annexin V and cell cycle was examined by fluorescent staining. Results The stable transfection of antisense Tcf in SMMC-7721 cells significantly reduced Tcf expression at both mRNA and protein levels. Compared with parental and mock-transfected 7721 (7721-vector) cells, antisense Tcf RNA transfected cells 7721-pTas showed much decreased activities of proliferation, migration and invasion in vitro. Furthermore, the apoptosis rate of 7721-pTas cells [(26.34±2.07)%] was significantly higher than that of 7721-vector cells [(6.53±1.02)%] and parental SMMC-7721 cells [(4.33±0.68)%] (P<0.001). The percentages of G0-G1 phase antisense transfected cells were 20.24% and 20.95%, higher than parental SMMC-7721 and 7721-vector cells, and percentages of S phase antisense transfected cells were 11.8% and 11.38%, lower than parental SMMC-7721 and 7721-vector cells, respectively. Conclusions Antisense RNA suppress the growth ability of liver cancer cells by inducing cell apoptosis and impeding the progress of cell cycle, which suggests that selective blockage of abnormal Wnt signal pathway by antisense Tcf RNA may be a potential new gene therapy for liver cancer.
