Objective To evaluate and compare the therapeutic effects of suprapubic transvesical prostatectomy (SPPC), Madigan prostatectomy (MPC) and transurethral electrovaporization ablation prostatectomy (TUVP) for the treatments of symptomatic BPH. Methods 216 symptomatic BPH patients randomly underwent SPPC(n=87), MPC(n=45) or TUVP(n=84) respectively and their therapeutic effects were evaluated. Results There are significant improvements in symptoms and physical signs in each group after operation. The morbidity rates of post-operative complications in SPPC,MPC and TUVP were 31 0%,11 1%,13 1% respectvely. SPPC group showed the longest average operative time and the most blood loss, both of which were the least in TUVP group. Conclusions SPPC was the most effective among the three procedures, but the trauma of SPPC to the patient was the most. Complication of MPC was the least. TUVP was the safest procedure with the least injury.

objective: To investigate the effects of cerium oxide content on the color of alumina glass composite. Methods: Infiltration glass powder with different content of cerium oxide (1%～4%) were fabricated. Alumina glass composite was prepared by infiltrating molten glass into presintered alumina block at 1 250 ℃ for 2 h, and the color of the alumina glass composite were measured with Minolta chromatic instrument(CR 321) . For comparison, the color of VITA In Ceram alumina technical shade guide was recorded too. Results: After infiltration, the b * range of the alumina glass composite was in accord with that of the shade guide. With the increasing content of the cerium oxide, a *, b * and chroma increased, L * decreased, the hue of the alumina glass composite shifted from yellow green to yellow red. Conclusion: Cerium oxide may effectively enhance b * of the alumina glass composite, but its ability of reducing L * and enhancing a * is weak.

Objective: To measure the color of dental CAD/CAM alumina-glass-composites(AGC). Methods: Dental CAD/CAM alumina block were infiltrated at 1 120 ℃ by laboratory made AG1,AG2,AG3 and AG4 color serials of infiltration glass powder and Vita In-Ceram Alumina AL1,AL2,AL3 and AL4 infiltration glass respectively. Specimens were made with the area of 10 mm?10 mm,thickness of 0.5,1 and 1.5 mm respectively. Color parameters were measured by Minolta CM-2600d spectrophotometer. Results:The specimen with the thickness of 1 mm was used as the standard for color measurement.After infiltration with AL1-AL4 glass powder,the color parameters of Vita alumina core ceramic were L*: 69.39-78.41,a*:1.82- 4.02,b*:18.35-24.42,when infiltrated with AG1-AG4 glass powder, the color parameters of CAD/CAM AGC were L*:68.80-78.44,a*:1.32- 4.75,b*:16.85- 21.86. b*value and chroma of the AG3 core ceramic were lower than that of AL3 core ceramic,while a* value was higher.b* value and chroma of the AG1 and AG2 core ceramic were lower than that of AL1 and AL2 core ceramic. The reflectance curve of CAD/CAM AGC infiltrated by AG1-AG4 glass powder demonstrated the similar trend as that of the core ceramic infiltrated by Vita In-Ceram glass powder. Conclusion: The color range and surface reflection rate of laboratory made AG1-AG4 AGC are similar with those of Vita AL1-AL4 In-Ceram Alumina core and may meet the need of color match with veneer ceramics.

Objective To evaluate the effect of operation associated with uterine arerial chemotherapy and embolization preoperation.Methods 31 patients with pathologically confirmed cervical carcinoma were treated with interventional therapy,followed by uterectomyandpelvic lymphadenectomy.Results Curative effect was obvious.The lymph metastasis of Ⅱ and Ⅲ stage was 12% and 66.67%respectively.27 patients followedup for 3 years,23 were survived(85.19%).Conclusion For cervical carcinoma,before operation,the interventional therapy can reduce the size of tumor and the metastasis of lymph,improve the ectomy by operation and the survival rate.
