OBJECTIVETo determine the expression of bone morphogenetic protein 2 and 4 (BMP-2 and BMP-4) in prostatic carcinoma (PCa) and investigate their relationship with clinical stage and Gleason score of tumor.

METHODSForty-eight PCa cases and 5 normal prostatic tissue were analysed for the expressions of BMP-2 and BMP-4 by Western bolt assay.

RESULTSThe optical densities of BMP-2 expressions in the tumor with Gleason score < or =5, 6-8, and > or = 9 were 7547.1 +/- 1964.12, 9657.4 +/- 2010.54, 12467.7 +/- 2496.75 and of BMP-4 expressions were 5174.4 +/- 1400.54, 5940.3 +/- 1587.42, 6332.1 +/- 1647.83, respectively. The optical densities of BMP-2 expressions in the tumor in T1 - T2 and T3 - T4 stages were 8003.37 +/- 1889.23, 12385.55 +/- 2506.72 and of BMP4 expressions were 5267.41 +/- 1 464.19, 6543.75 +/- 1668.46, respectively. There were significant differences between tissues with Gleason score < or =5 and > or =9 (P <0.01), and tissues in T1 - T2 and T3 - T4 stages, in expressions of BMP-2 protein. The expression of BMP-2 protein was significantly high in the PCa with bone metastasis compared with that without bone metastasis.

CONCLUSIONThe expressions of BMP-2 and BMP-4 increase with the progression of clinical stage and Gleason score compared with normal prostatic tissue. The expression of BMP-2 protein is significantly upregulated in bone metastasis of PCa, which indicates a poor prognosis.

Background Bevacizumab is primarily aimed at pathologic angiogenesis for off-label uses such as the treatment of ocular neovascular disorders.However,as a new anti-fibrotic and anti-angiogenic agent following trabeculectomy,the safety and efficacy of bevacizumab by multiple-time and high-dose subconjunctival injection are still under study.Objective This study was to assess the safety and efficacy of bevacizumab after multiple-time and high-dose subconjunctival injections.Methods Regular trabeculectomy filtration surgery was performed on both eyes of 18 clean New Zealand White rabbits 0.1ml of bevacizumab(25g/L) was subconjunctivally injected intraoperatively and 3,5,7 days postoperatively in the left eyes of rabbits,and no any intervene in the right eyes were as normal controls.Bleb morphology was examined every 2 days and graded based on Moorefield's criteria and compared between the bevacizumab-treated eyes and normal saline(NS) eyes.The animals were sacrificed at 10,20 and 30 days after surgery respectively.The histopathological changes of the blebs were detected by hematoxylin and eosin stain to evaluate the cellular element around the bleb,and Masson stain was used to assess the degree of fibroblast proliferation.The degree of vascularity of bleb was identified by anti-vWf stain.Approval of this protocol was obtained and permitted from People's Hospital Institutional Animal Care and Use Committee of Peking University.The use of experimental animals complied with the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results Compared to the NS-treated eyes,bevacizumab-treated eyes showed the larger and more diffusely elevated blebs with the significant difference(2.48±0.22cm2 versus 1.73±0.27cm2,t=5.194,P＜0.05).The survival time of the filtration bleb in bevacizumab panel was longer in bevacizumab-treated eyes compared to control eyes,showing a significantly difference between them(21.0±1.56 days versus 12.5±1.97 days,t=3.830,P=0.005).Histological and immunohistochemical analysis confirmed that bleb and adjacent conjunctiva vascularity(A value) was significantly less in bevacizumab-treated eyes than that in control eyes at 20 days after surgery with the difference value 14320.7±4134.9(t=12.275,P＜0.05),and fibroblast deposition value was evidently diminished after bevacizumab treatment at 30 days following surgery in comparison with control eyes with the mean difference 0.27±0.03(t=15.980,P＜0.05＝.Conclusion Repeated subconjunctival injection of bevacizumab can effectively prolong the survival time of bleb in a rabbit model of trabeculectomy and limit the degree and area of vascularization in 30 days following surgery.Bevacizumab inhibit fibroblast-meditated tissue formation significantly in the later phase of vascularization after trabeculectomy.

AlM: To evaluate the effect of rigid gas permeable contact lens ( RGP ) in correcting high myopia and astigmatism.METHODS: Forty-one patients ( 65 eyes ) with myopia (-9. 03 ± 6. 19DS, maximum -23. 00DS) and astigmatism (-1. 41 ± 1. 32DC, maximum -5. 50DC) were fitted with RGP after strict routine ophthalmological examination, objective refraction and subjective refraction. All these patients were followed after 1wk, 1, 3mo and half one year.RESULTS:Sixty-five eyes were fitted with RGP (-9. 92± 5. 96DS). RGP base curve ( BC) was majorly located within the range 7. 20 ~8. 25mm. 46. 2% eyes with RGP achieved 1. 0 ( BCVA ) and 80. 1% achieved above 0. 6 ( BCVA) . However, with spectacles, the percent was 28%(1. 0) and 60% (>0. 6), respectively. BCVA of RGP was 0. 81 ± 0. 22, but BCVA with spectacles was 0. 66 ± 0. 28, there was statistical significance (P<0. 01). There were 40 eyes (62%) fitted with RGP whose vision were enhanced more than 1 line, 24 eyes ( 37%) whose vision were not changed and 1 eye (2%) whose vision were dropped 1 line.CONCLUSlON:RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.
