Expression and significance of glutathione S-transferase mu 3 in prostate cancer / 中华泌尿外科杂志

Objective To explore the role and clinical significance of GSTM 3 ( glutathione S-trans-ferase mu 3) expression in prostate cancer (PCa). Methods We had used the two-dimensional fluores-cence difference gel electrophoresis ( 2D-DIGE) and mass spectral analysis to further verify the microarray data of mRNA expression profiling discovered .GSTM3 mRNA level was detected by Rael-time Quantitative PCR ( RT-QPCR) in 28 pairs of prostate cancer tissue and benign tissue .The relationship of GSTM 3 level with the serum PSA level and the clinical feature of PCa were analyzed . Results In 2D-DIGE study, we found that the expression of GSTM 3 protein in adjacent tissues was significantly higher than that in PCa tis-sues (P0.05) and prostate cancer clinical pathological parameters ( P>0.05). Conclusions GSTM3 expression is down-regulated in PCa tissues, and we may identify PCa by detecting the GSTM 3 expression .

Effect of Sporoderm-broken Spores of Ganoderma Lucidum in the Treatment of Partial Androgen Deficiency of the Aging Male / 广州中医药大学学报

[Objective] To investigate the effect of sporoderm-broken spores of Ganoderma Lucidum in the treatment of partial androgen deficiency of the aging male (PADAM) . [Methods] Random number table was used for the division of 138 PADAM cases. Sporoderm-broken Ganoderma Lucidum spores capsules were given orally to group A (n=80) and placebo to group B (n=58). The treatment course lasted 3 weeks. Self-scoring of physical ability, vasomotoricity, mental psychological state and sexual function was used to evaluate the therapeutic effect. Meanwhile, blood contents of testosterone (T), erythrocyte superoxide dismutase (SOD) and malondialdehyde (MDA) were determined and adverse reaction was observed. [Results] After a 3-week treatment, the scores of physical ability, vasomotoricity, mental psychological state and sexual function were decreased in group A (P 0.05) and the difference was significant between the two groups (P

An experimental study on the blood-prostate barrier penetration of silicon nanoparticles / 中华泌尿外科杂志

Objective To study the biological behavior of silicon nanoparticles in penetrating the blood-prostate barrier. Methods Silicon nanoparticles were prepared by means of chemical procedures.The silicon nanoparticles were added into HT1080 cells and cultured for 48 h to observe the distribution of nanoparticles in the cells.The nanosuspension at gradient concentration (0.005,0.010,0.015,0.020,0.025 ml/g)was injected into 100 mice (20 mice of each group) intraperitoneally or via tail vein to study the distribution of nanoparticles in the prostate.Additional 20 mice served as controls.The mortality and toxic reaction at 2 weeks after injection were also recorded. Results Electronic microscopy confirmed the penetration of silicon nanoparticles into HT1080 cells,the prostate gland and interstitial tissue,with intracellular ultrastructure intact.There was no significant difference in body weight,diet,defecation and activities among the 5 treatment groups and control group. Conclusions Silicon nanoparticles can overcome the obstruction of drug transportation by blood-prostate barrier or other biomembranes and thus may be promising as a drug carrier in treatment of prostate diseases.
