Amniotic membrane transplantation for porous sphere orbital implant exposure

Objective: This study is aimed at describing the clinical outcome of amniotic membrane transplantation for exposure of porous sphere implants. Methods: A retrospective review of consecutive cases of porous sphere orbital implant exposure was carried out. Eight cases were presented between May 2004 and Oct. 2006 (5 males, 3 females; mean age 44.5 years). Six had enucleation and two had evisceration. Exposure occurred in two primary and six secondary. Orbital implant diameter was 22 mm in seven cases and 20 mm in one case. Six patients are with hydroxyapatite and two with high-density porous polyethylene (Medpor) orbital implants. The mean time from implantation to exposure was 1.1 months (range 0.8~2 months). All patients required surgical intervention. Results: The time of follow-up ranged from 3.0 to 28.0 months (mean 16.5 months). Amniotic membrane grafting successfully closed the defect without re-exposure in all of these patients. The grafts were left bare with a mean time to conjunctiva of about 1 month (range 0.8~1.5 months). Conclusion: Exposed porous sphere implants were treated successfully with amniotic membrane graft in all of patients. The graft is easy to harvest. This technique is useful, dose not lead to prolonged socket inflammation and infection, and it is valuable application extensively.     

《离骚》多元化的艺术风格及其成因

《离骚》作为屈原辞当之无愧的代表,不仅处处流露出屈原厚重而又令人景仰的生命体验,而且也鲜明打上了战国时代思想文化层层嬗变、层层演进的深深烙印.巫卜文化、史官文化、士人文化三种在发生学上界限严格的文化形态,都可以在《离骚》中找到相应的影响.个性化的生命体验和纷纭错杂的时代文化特征,加之楚民族特有的审美倾向,共同造就了《离骚》艺术风格多元化的综合气象.

The Design of Behavior Management Institution Based on Special Symbols and Measure Optimizing-Taking the Design of the Institution of Controlling the Pollution Behavior of Enterprises as an Example

Taking the institution design of controlling the pollution behavior of enterprises as an example, the symbol system specialized for the design and analysis of behavior management institution is put forward, which predigests the institution design greatly and make the process of institution design much like the engineering design. The measure combination method for improving the parameters of the institution, the arithmetic for calculating the validity of the institution and the arithmetic for calculating the behavior probability of the irrational managed are also put forward, which make the design and analysis technology of behavior management institution more practical.
