This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.

METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.

RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).

CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.

OBJECTIVETo detect the expressions of receptor tyrosine kinases (RTKs) mRNA and protein and to explore potentially promising tumor markers and conceivable drug target in bladder cancer.

METHODSThe expressions of RTKs mRNA and protein in tissue from invasive urothelial carcinoma of the bladder were examined by real-time quantitative PCR array and cytokine antibody array, with normal bladder tissue as control. The Results were analyzed using bioinformatic approaches.

RESULTSThe expressions of TGFA, STAB1, SERPINE1, ANGPT2, SPINK5, ANGPTL1, PROK1, MDK, CXCL9, GRN, RUNX1, VEGFA, and TGFB1 were obviously upregulated in bladder cancer tissue, while those of EDIL3, PTN, CCL2, PDGFD, FGF13, KITLG, FGF2, SERPINF1, and TNF were downregulated. ALK, Btk, EphB2, ErbB4, PDGFR-α, ROS, Tie-2, Tyk2, and VEGFR3 were over-expressed in bladder cancer, while FRK, Fyn, IGF-IR, Insulin R, Itk, JAK1, JAK3, and LCK were low-expressed.

CONCLUSIONVascular endothelial growth factor/platelet-derived growth factor-targeted therapies may play an active role in treating carcinoma of bladder.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

Acute coronary artery syndrome (ACS) was confirmed by coronary arteriography in 398 patients,and 378 healthy persons served as the control group.Serum uric acid in ACS and control group showed normal distribution,and serum uric acid level in ACS group (322?107 )?mol/L was significantly higher than those in control group (302?77)?mol/L (P＜0.01 ).The prevalence of hyperuricemia (HUA) was 27.0% in male patients and 25.2% in female.Systolic blood pressure,diastolic blood pressure,fasting plasma glucose,total cholesterol,triglycerides,creatinine and blood urea nitrogen in ACS group were higher than those in control group (all P＜0.01 ).Muhivariable analyses adjusted for age and sex indicated that raised fasting plasma glucose,total cholesterol,uric acid and mean arterial pressure were risk factors for coronary artery stenosis in ACS,and HUA played a role in the pathogenesis of ACS.

Background Retinal neovascularization disease is a common cause of blinding.Retinal neovascularization is related to enhancing proliferation of vascular endothelial cells.So how to inhibit proliferation of vascular endothelial cells is a hot burning issue.p21 is known to be involved in the regulation of cell cycle and therefore inhibit the cell proliferation.However,the relationship of p21 and the proliferation of vascular endothelial cells in retinal neovascularization disease is for further study.Objective The aim of this experiment was to study the proliferation of rhesus retinal vascular endothelial cells(RF/6A) and expression of p21 in RF/6A cells under the hypoxia condition,and discuss their association.Methods The RF/6A cells were cultured and passaged in vitro,then they were randomly divided into normoxia culture group(5％ CO2 +95％ O2) and hypoxia for 1 hour,3,6,12 hours group(1％ 02+5％ CO2 +94％ N2).Flow cytometer(FCM) was used to check the distribution of RF/6A cell cycle in the normoxia culture group and hypoxia for 1 hour,3,6,12 hours groups.MTT assay was used to detect and compare the cell proliferation(A570)among the various groups.The expression of p21 in the cells was analyzed by Western blot.Results FCM showed that the cells proportion of G0/G1 stage was reduced initially and then increased afterward in hypoxia for 1 hour and 3,6,12 hours groups,showing a significant difference among 5 groups (F =20.083,P =0.000),and the cells proportion of S stage and G2/M stage were increased firstly and then declined in different hypoxia groups with statistical significances (F =7.861,P =0.001 ; F =10.305,P =0.003).Compared with normoxia culture group,cells proportion of G0/G1 stage was declined and that of S stage and G2/M stage were raised after hypoxia culture,showing statistically signifcant differences(P＜0.05).MTT showed that cell multiplication capacity(A570 value)strengthened firstly and then weakened in hypoxia groups with time prolongation,showing a significant difference among all the groups(F=7.768,P=0.001),and A570 value in hypoxia for 3 hours and 6 hours groups (0.315± 0.062,0.365 ± 0.064) was significantly higher than that of the normoxia group (0.205 ± 0.063),respectively(P＜0.05).Western blot showed that the expression of p21 in the cells down-regulated at the beginning and then up-regulated with the increase of hypoxia time,and there was statistical significance (F =16.738,P=0.000).The p21 relative levels in different hypoxia groups were reduced in comparison with the normoxia group,showing statistical signifcances(P＜0.05).Conclusions Short-term hypoxia could reduce the expression of the p21 in RF/6A and induce cell proliferation initially,then p21 increases and cell proliferation is inhibited with the prolongation of hypoxia time.
