Objective To investigate the effects of the EGF on isolation and cloning of mouse embryonic stem-like cells from PGCs. Methods EGF with different density were added to the culture medium of cells .After a culturing period ,the cloning number of mouse embryonic stem-like cells and the topmost passage would be observed and registered. Results There was not obvious effects on the primary culture of mouse ESC and was distinct on the later passage if EGF were used. Conclusions In the primary passage of mouse ESC may survive without EGF,and the impact of the existence of EGF was better than the one of the inexistence to the cloning of mouse ESC.

Objective To evaluate the clinical effect of Medpor ( porous high density polyethylene )as a padding material in correction of sunken eyelid after hydroxyapatite (HA) implantation. Methods We used Medpor in 17 patients ( 10 male and 7 female ), aged from 18 to 43 years (mean 26.6 years ), in which 9 cases had concomitant orbital fractures. The Medpor was implanted after HA sphere implantation ranged from 2 to 19 months ( average 6.7 months ). 17 consecutive patients with implantation of HA sphere were filled with Medpor under the periosteum. All of the cases were examined by CT scanning to distinguish orbital lesions with or without fracture. In the orbital fracture cases, we first repaired orbit bone defects with Medpor. Results There were no secondary infection or implant rejection occurred after following up for 1 to 18 months (average 8.7 months ). All patients' cosmesis was acceptable. 14 of 17 patients gained symmetric appearance. Although 3 patients had slight sunken eyelid, they gained a dramatic improvement of facial appearance nevertheless. Conclusions Sunken eyelid after HA sphere implant is related with orbital fracture as well as relative reduction of orbital content. Medpor presents fine biological compatibility. It is also easy to remodel and fix during operation. Medpor is a good implant for treatment of sunken eyelid after HA sphere orbital implantaion. [

Objective To evaluate the middle and long term effects of the two-stage procedures of drilling for hydroxyapatite orbital implant and inserting a motility peg, and to investigate the pathogenesis and treatment of the various complications during the procedure. Methods This retospective study included 68 patients who had underwent the drilling of the hydroxyapatite and motility peg placement for over 3 years. Mean age at operation was 30.7 years (range from 17～60 years). All patients were placed plastic peg. Information recorded included pre-and post-operative facial appearance, motility of the artificial eye, conjunctival sac discharge and other complications. Results No secondary infection occured in 36～72 months of follow up. All patients felt that there had been an improvement in the motility of their artificial eye. And their cosmetic appearance was acceptable. The most frequent complication encountered was discharge from conjunctiva sac, which occurred in 31 patients. Extrusion of the motility peg was found in 6 patients. 5 patients had exuberant granulation in conjunctiva sac. Conclusion Drilling of the hydroxyapatite implant improves both the appearance and the motility of the artificial eye. Complications are minor and can be easily prevented and treated. The vascularization of HA sphere with good motility should be drilled at relatively larger conjunctival sac in the patients who can cooperate under local anesthesia.
