OBJECTIVE: To evaluate the osteogenetic character and repairing maxillary sinus superior wall fractures capability of calcium phosphate cement (CPC) before and after combined with recombinant human bone morphogenetie protein-7(rhBMP-7). METHOD: A 10 mmX5 mm bone defect in the maxillary sinus superior wall was induced by surgery in all 24 New Zealand white rabbits. These 24 rabbits were randomly divided into two groups. The defects were repaired with CPC group (n = 12) and CPC/rhBMP-7 group (n = 12). The osteogenesis of bone defect was monitored by gro'ss observation, histological examination, observation under scanning electron microscope and measurement of ALP activity at 6 and 12 weeks after the implantation. RESULT: In group CPC,new bone was found to form slowly and little by little. In group CPC/rhBMP-7, however, new bone was observed to form early and massively. The ALP activity in group CPC showed significant statistical difference with that of group CPC/rhBMP-7 (P < 0.05). CONCLUSION The CPC/rhBMP-7 composite has osteoconductibility and osteoinductibility, comparing the use of CPC/rhBMP-7 with CPC for the repair of orbital fracture, the former show obvious advantage repairing ability in maxillary sinus superior wall defect.

? AIM: To investigate the differences between synoptophore and triple prism strabismometry and its possible cause.?METHODS: There were 347 patients with horizontal concomitant strabismus involved, in which 76 patients were esotropia, 37 patients were male while 39 were female, with average age of 13. 27 ± 7. 77 years old. There were 271 patients with exotropia, 131 cases were male while 140 were female, with average age of 15. 43 ± 8. 42 years old. All the patients were examined by synoptophore and prism plus shaded strabismometry in a long distance of 6m. Datas were analyzed by SPSS 17. 0.?RESULTS:In the exotropia patients, the conversions of circular degree(°) and prism degree(△) were:1°=0. 29△ ~1. 78△, which was statistically significant with intermittent strabismus (P=0. 001). While in the esotropia patients, the conversions were:1°=2. 01△ ~2. 15△.?CONCLUSION: The diversity between the two methods is enlarged with the increase of squint angle for exotropia patients. While in esotropia patients, the diversity decreased with the increase of squint angle. Synoptophore equipped with +7. 00D, defects of the triple prism itself and proximal convergence during exam may be the reasons for the diversity.

In the present study, the AC impedance of rat blood was measured with Agilent 4294A impedance analyzer in the frequency range of 10(4)-10(8) Hz, and the effect of simulated weightlessness (SWL)on electrical properties of rat blood was investigated by analyzing the data characteristics with the use of electrical impedance spectroscopy, the Bode diagram, the Nyquist diagram and the Nichols diagram. The results demonstrated 60 days SWL caused some changes: (1) the electrical impedance of rat blood were reduced, mainly in the real part of complex impedance (Z'o and Z'infinity), the electrical impedance modulus amplitude (|Z*|o and |Z*|infinity), the impedance relaxation strength (deltaZ', delta|Z*|) and the logarithm of impedance modulus amplitude at low frequency (Log |Z*|o) were lower than that in the control (CON) group; (2) the characteristic frequency of the electrical impedance spectrum of rat blood and the phase angle were increases, mainly in the characteristic frequency (fc1, fc2) and the phase angle [theta(p) (degree), theta(p) (radian)] increased compared with that in the CON group. These data indicate that SWL leads to reduced resistivity and enhanced conductivity of blood.
