ABSTRACT
PURPOSE: To evaluate the clinical application of base bonding customized zirconium abutment. METHODS: A total of 141 base bonding customized zirconium abutments used in 114 implant-supported cases during 2010.6-2012.11 in Hangzhou Stomatology Hospital were involved in the study. To evaluate the efficacy, they were followed up for 3 months to 2 years. RESULTS: Among 141 abutments, 140 were successfully applied to implant prosthesis at first time. During the observation period, partial zirconia exfoliation from bases occurred in 1 abutment. All the patients and dentists were satisfied with the final esthetic outcomes. CONCLUSIONS: The clinical effect of base bonding customized zirconium abutment is acceptable.

OBJECTIVE: To explore the effect of extracted liquid from Qianlietongyu on the proliferation or apoptosis on prostatic smooth muscle cells in vitro. METHODS: After extracted liquid from Qianlietongyu treated the cultured prostatic smooth muscle cells, the anti proliferative and apoptotic indices were assessed by MTT assy and terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) respectively. RESULTS: There was a significant dose-effect relationship between the concentration of extracted liquid from Qianlietongyu and the antiproliferative index on prostatic smooth muscle cells in vitro (P < 0.01), but there was no markedly difference in the apoptosis index between the group of extracted liquid from Qianlietongyu and control group ( P > 0.05). CONCLUSION: Extracted liquid from Qianlietongyu may show significant antiproliferative effect on prostatic smooth muscle cells in vitro, without inducing apoptosis.
