AIM: To investigate the biocompatibility and therapeutic effects of polyetheretherketone(PEEK) on recovery of a rabbit orbital ***: Totally 16 New Zealand rabbits were used to establish an orbital bone defect model and then randomly divided into two groups. PEEK was implanted in the experimental group. The control group was blank, and no substance was implanted. The model rabbits were sacrificed at 4 and 8 wk, and examined by general observations, histology, electron microscopy, Western blotting, and realtime polymerase chain ***: No infection or rejection occurred after PEEK implantation, and biocompatibility was good. The relative expression of vascular endothelial growth factor(VEGF) protein in the experimental group was significantly higher than that in the control group postoperatively(P<0.05). Bone defect repair in the experimental group was significantly better than that in the control group in the same period and some osteogenesis was ***: PEEK has good biocompatibility and efficacy for the treatment of orbital bone defects in a rabbit model.

An expert system skeleton tool of sintering process was constructed using object-oriented method, which can actualize two functions, i. e. , the shell function and the program function. The skeleton tool offered a platform to build a prototype system, to program class code, and to develop the expert system. Four branch expert systems were developed using the skeleton tool including the control of chemical composition, the control of sintering process state, the control of expended energy, and the diagnosis of abnormity. It is found that the performance of all systems is satisfactory in practice.
