BACKGROUND:The functional reconstruction of large maxillary defects is a significant challenge due to the lack of bony support.In this paper.a new approach for segmental maxillary reconstruction and bony support foundation is put forward and tested by animal experiment.OBJECTIVE:To evaluate the possibility of segmental maxillary regeneration by internal curve distraction osteogenesis of zygoma with the self-developed distractor.DESIGN:Animal experiment.SETTING:Department of Stomatology.the 252 Hospital of Chinese PLA.MATERIALS: Two healthy female hybrid canines of 1-1.5 years old and 20-25 kg were selected. Internal curve distractor was composed of three parts:curve track,movable part and a flexible central thread bar fixed at the center of the curve track.The former two parts,which was made of TC4,(Ti-6AI-4V),and the flexible central thread bar was made of nickel titanium wire. A 360° of counter clockwise rotation of the distraction activator achieved an advancement of 0.35 mm for the movable part;the maximum distraction length allowed by the distractor was 25 mm.METHODS: The experiment was carried out in the animal experimental center of Fourth Military Medical University of Chinese PLA from October 2003 to February 2004. The segmental defect of 18-20 mm in width was made in maxilla and zygoma to simulate maxillary defects.Then an osteotomy distal to the defect was performed to create the variable transport disk. The distractor was fixed to the residual zygoma and zygomatic arch for internal curve distraction osteogenesis.After a latency period of 5 days,the distraction started at a ratio of 1.05 mm per day (0.35 mm once,3 times per day) for 13 consecutive days. Before and after distraction and at the second, fourth and eighth week of consolidation, the bone radiographs of residual zygoma and zygomatic arch were taken routinely.MAIN OUTCOME MEASURES: The general condition of the animals and distractor, and the quality and quantity of new formation bone in the distracted gap.RESULTS:Canines and distractor were in good condition during the experimental period.X-ray film showed that at the end of distraction, the bony transport disks were distracted about 12 mm around arc.At the 8th week of consolidation,the density of new bone was close to that of normal bone,and the curved bony regeneration was almost completed.CONCLUSION: The serf-designed curve internal distractor is fit the condition of major maxillary defects,and could be used for the internal curve distraction of zygoma.

Objective To assess the efficacy of the mixtures of different concentrations of ropivacaine(R) and chloroprocaine(C)for epidural anesthesia in patients undergoing hysterectomy.Methods Sixty ASAⅠorⅡpatients aged 27-56 weighing 45-75 kg undergoing elective hysterectomy were randomly divided into 4 groups(n= 15 each);groupⅠ0.75% R alone;groupⅡ0.5% R-1% C;groupⅢ0.5% R-1.5% C and groupⅣ0.75% R+1% C.The epidural catheter was placed at L_(2,3)interspace and advanced 3.5 cm into the epidural space in cephalad direction.A total of 22 ml of epidural solution was injected in each group.The onset time,block height and duration of sensory block and the onset time,degree and duration of motor block(using Bromage scale)were assessed.The use of supplementary drugs(ketamine and ephedrine)and side effects were recorded.Results The onset time of sensory and motor block was significantly shorter in groupⅡ,ⅢandⅣthan in groupⅠ(0.75% R alone).The duration of sensory and motor block was significantly shorter in groupⅡandⅢthan in groupⅠandⅣ.The incidence of hypotension was significantly increased but the incidence of discomfort produced by traction on the viscera during operation was reduced in groupⅣas compared with groupⅠ.Conclusion The anesthetic efficacy of epidural 0.5% ropivacaine is significantly enhanced when mixed with 1.0% or 1.5% chloroprocaine.

Objective To investigate the prevalence of urinary incontinence among Uigurs in Xinjiang district. Methods 506 adults Uigurs (over 18 years old)in Xinjiang, 200 men and 306 women, were interviewed with questionnaire. Results The total incidence of urinary incontinence was 38.9%, 43.8% in women and 31.5% in men, P

Professor SONG Nanchang's clinical experience and characteristics for treatment of peripheral facial paralysis are introduced. In clinical treatment, professor SONG has adopted staging treatment strategy, and performed acupuncture stimulation with different levels. He attaches great importance to the acupoint selection on distal limbs. For the treatment on the face, he takes temperature as necessity; he inherits from famous Chinese doctor ZONG Ruilin's acupuncture technique of slow-twisting and gentle-pressing. Meanwhile, he excels in combination, of different therapies, using acupuncture, moxibustion, electroacupuncture, auricular point sticking, Chinese herbal medicine, etc. according to individual condition and disease stages. He also emphasizes on psychological counseling and daily life care to achieve rehabilitation within the shortest time.

Objective To investigate the transfection and expression of pcDNA3 1-VEGF 165 plasmid in mammalian cells. Methods pcDNA3 1-VEGF 165 plasmid was transfected into CHO cells by electroporation and the positive clones were screened by G418. The expression of VEGF 165 gene in the transfected CHO cells were detected by RT-PCR, ELISA and western blotting analysis. The biologic activities of VEGF 165 secreted by the transfected CHO cells were measured by Mile's assay and MTT method. Results G418-resistant CHO cell clones were obtained. RT-PCR, ELISA and western blotting analysis showed that there were the transcription and translation of VEGF 165 gene in anti-G418 CHO cells. The mile's assay showed that the expressed VEGF 165 could increase the vessel permeability, and MTT assay proved that it could promote the proliferation of endothelial cells. Conclusion pcDNA3 1-VEGF 165 plasmid could express VEGF 165 with biological activities in mammalian cells.
