Objective To study the effect of grape seed procyanidin extract(GSPE) on the cell cycle arrest in human bladder cancer BIU87 cells and investigate the underlying molecular mechanism.Methods BIU87 cells were treated with different concentrations of GSPE(50,100 and 200 ?g/ml) and cultured for 24 h.The untreated group served as control.Flow cytometry was used to evaluate the cell cycle,and RT-PCR and Western blotting were used to detect the mRNA and protein expressions of CyclinD1 and cyclin-dependent kinase 4(CDK4).Results GSPE inhibited the cell growth through cell cycle arrest at G1 phrase in a dose-dependent manner.Semi-quantitated RT-PCR and Western blot analyses indicated that GSPE decreased CyclinD1 and CDK4 expressions in a dose-dependent fashion(P

Objective: To compare the concentration of IL-1? in the apical exudates of phoenix abscess of chronic periapical periodontitis and to examine the correlation of IL-I? concentration with clinical and radiographic findings of the involved teeth. Methods: 35 single-rooted teeth diagnosed as phoenix abscess and 35 as chronic periapical periodontitis were examined. The periapical signs and symptoms were recorded. Radiographs were taken and periapical radiolucent areas were calculated with the help of the AutoCAD software. The standard paper-point sampling method was used to collect and quantify the periapical exudates. IL-1? in the exudates was detected by enzyme-linked immunosorbent assay (ELISA). All statistical analyses were finished with SPSS 10.0 software. Results: The phoenix abscess group showed significantly lower concentration(5.65?2.76) ng/ml of IL-1? in the exudates and larger radiolucent areas(32.10?13.82) mm 2 on the X-ray films than the chronic periapical periodontitis group[(12.51?5.15) ng/ml and (6.51?3.56) mm 2 respectively] (P

OBJECTIVE:To provide some references for rational application of intravenous infusion drugs to ensure the safety of drug use. METHODS:Statistical analysis was made to irrational prescriptions intercepted by the pharmacy intravenous admixture service of our hospital from 2009 to 2013. RESULTS:There were 5,802 groups of irrational prescriptions from 2009 to 2013,accounting for 0.12% of total prescriptions. For the irrationality,the top three reasons were improper solvent dosage, drug overdose and improper solvent selection in order,and the involved types of drugs were mainly antimicrobial agents,anti-neoplastic drugs,common drugs and parenteral nutrition drugs (arranged from more to less). Under the pharmacist’s interven-tion,the percentage of irrational prescriptions of intravenous drugs reduced from 0.169 4% in 2009 to 0.082 8% in 2013. The decrease in the irrational prescriptions involving with improper administration was the most significant,followed by those related to drug overdose,frequency,prescribing errors errors improper solvent dosage,incompatibility and improper solvent. CONCLU-SIONS:Pharmacists’intervention can effectively reduce the irrational prescriptions and significantly promote rational use of in-travenous drugs.

Objectives To establish real-time fluorenscence quantitative polymerase chain reaction ( RFQ-PCR ) for measurement of the expression level of guanylyl cyclase-C(GC-C) in the Peripheral blood mononuclear cell(PBMC)in 30 blood donors, 10 cases colorectal cancer tissue and 1 case T84 human colon cancer cell line. Methods Specific primers and TaqMan probe have been designed,and fluorenscence of the PCR product was detected continuously during amplification. According to the standard curve created by plasmid DNA, the expression level of GC-C in clinical samples has been determined using software, and the results were presented as the ratios of GC-C mRNA to?2-microgluobulin(?2M)mRNA. Results The detection range of the assay was from 101 pg/ml to109pg/ml,the coefficient of variation values of both intra-experimental and inter- experimental reproducibility were 6. 87% to 11. 12% and 8. 86% to 15. 19% . None of 30 blood donors and 11 benign intestinal patients expressed GC-C mRNA,it was expressed in 31/37 colorectal cancer patients. The expression level of GC-C mRNA in colorectal cancer patients was 0. 88?0.06,and the expression level of its in colorectal carcinoma tissue and T84 cells were 0. 86?0.07/ug tissue and 0.0082/per cell. Conclusions This assay had high sensitivity,specificity and reproducibility.

Objective To investigate the infiltration of dendritic cell (DC) in Vocal cord polyp, laryngeal leukopla-kia and glottic squamous cell carcinoma,and to observe laryngeal mucosal lesions of the state of the immune microenviron-ment, and to research significance of DC on the development of glottic squamous cell carcinoma. Methods The infiltration of S-100+and CD83+DC in 20 cases of Vocal cord polyp, 47 cases of laryngeal leukoplakia, 45 cases of glottic squamous cell carcinoma tumor and 20 cases of laryngeal normal mucosa were examined using immunohistochemistry. Results The num-ber of S-100+and CD83+DC were significantly higher in glottic squamous cell carcinoma, laryngeal leukoplakia and vocal cord polyp than that in laryngeal normal mucosa (P<0.05). The number of S-100+and CD83+DC were higher in laryngeal leukoplakia than that in glottic squamous cell carcinoma (P<0.05). The number of S-100+and CD83+DC in mild dysplasia and moderate dysplasia were less than that in severe atypical hyperplasia (P<0.01). In glottic squamous cell carcinoma, S-100+ and CD83+DC with poor-differentiated was significantly less than that with well-differentiated (P < 0.01). Conclu-sion Changes in the number of dendritic cell was found in vocal cord polyp, laryngeal leukoplakia and glottic squamous cell carcinoma, which indicated that there were an abnormal immune status. Changing of dendritic cell in laryngeal mucosa plays an important role in laryngeal cancer development.
