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 isolate and identificate a specific new gene highly related to human bladder cancer and to investigate the carcinogenesis mechanism and genetic susceptibility. Methods Normal bladder epithelia and cancer tissue collected from 8 cases of primary bladder transitional cell carcinoma were studied using the high performance?sensitive technique of mRNA differential display.The differential fragments were found by comparing with genetic expression. 6 of them were reamplificated?cloned?sequenced,and performed the autoploidy index in the public database of genbank. Results (1)37 differential fragments have been isolated.36 of which are expressed or highly expressed in cancer tissues,but not so or lowly expressed in normal tissues;while it has been expressed in 1 normal tissue but not in the cancer tissue.(2)Results of indexing:1 is homologous to TBX3 (T box gene),autoploidy 99%.1 is homologous to cl.Ca4 gene (member 4 of Calcium activated chloride channel gene family), autoploidy 99%.1 is homologous to Cu,Zn SOD gene (Cu,Zn superoxide dismutase),99%.The remaining fragments are not homologous to unknown sequences in the public database of genbank,assigned as YHHQ1,XHL,LHX. Conclusions (1)It is verified at genetic level the relation between the conment's increasing of Cu,Zn SOD in bladder cancer derived tissue and the occurrence,advance of bladder cancer.(2)The relation between TBX3,cl.Ca4 gene and human carcinoma has been observed.(3)YHHQ1 may be the new candidate of anti oncogene related to bladder cancer.XHL and LHX may be the new candidates of oncogene related to bladder cancer.

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.
