Objective To study the differences in the inclination of lower incisors among the female patients with beautiful profiles in different vertical skeletal types so as to provide the clinical treatment design for a certain guiding. Methods 137 cephalometric films of female patients with beautiful profiles were selected and divided into three groups based on the vertical facial types(∠SNMP):small degree(n = 31),average degree(n = 89) and larger degree groups(n=17). The angles of∠L1/MP and∠L1/A-Pog were measured and treated with covari-ance analysis for detecting the differences between the groups. Results The index of L1-MP(°)was the smallest in the larger degree group,the largest in the small degree group and average in the average group,with significant differences between the three groups(F = 17.38,P < 0.001). There was no significant differences in ∠L1/A-Pog (°)(F=2.61,P>0.05). Conclusion Lower incisors have compensatory inclined lingually in the group of higher mandible angle,but labially in the group of lower mandible angle.

OBJECTIVETo research the clinical application of lower cervical pedicle screw fixation procedure.

METHODSFrom September 2011 to July 2013,32 patients underwent posterior pedicle screw-rod system fixation were retrospective analyzed includinig 20 males and 12 females with an average age of 56.4 years old ranging from 21 to 78 years. Among them, 10 patients were traumatic cervical spinal injury, 9 patients were cervical spinal canal tumors, 7 cases were posterior longitudinal ligament ossification of cervical vertebrae, 6 cases were multiple segmental cervical spondylopathy. Preoperatively, X-ray, computed tomography, magnetic resonance imaging and magnetic resonance angiography of the vertebral artery were performed in all patients. After the operation and during the follow-up,X-ray and computed tomography were performed to confirm the pedicle screw position. The accuracy of the pedicle screw placement was evaluated by 4 grades classification from Lee. The spinal cord function was assessed by ASIA impairment scale for traumatic patients and JOA score for non traumatic patients.

RESULTSTotally 144 pedicle screws performed on 32 patients from C3 to C7 involving 132 screws of grade 0,5 screws of grade 1,5 of screws grade 2 and 2 screws of grade 3 according to postoperative CT. There were 12 screws penetrating the pedicle cortex including 8 screws at lateral,2 screws at caudal, 1 screw at medial and 1 screw at cranial. The follow-up time was 12 to 33 months with an average of (21.0±1.5) months. The spinal cord function was not improved in 6 complete cervical spinal cord injury patients,but their paraplegic level descended 1 to 3 segments. Four incomplete cervical spinal cord injury patients' ASIA impairment scale was increased by 1 to 2 grades in average. The JOA score of 22 atraumatic patients increased from preoperative 11.5±0.8 to 15.9±0.6 of postoperative at 6 months (P<0.01). There were no screw loosening,screw pullout and screw-rod breakage.

CONCLUSIONThe lower cervical pedicle screw fixation can provide excellent 3D stability of the vertebral column. The operation risk and Complication could be minimized by adequate preoperative evaluation for appropriate cases and individual pedicle screw placement. It deserved the clinical expansion.

BACKGROUND: There are currently many cryopreservation methods for the aminotic membrane, which have varying effects on the ultrastructure and biological activity of amniotic membrane, but on no one is effective.
OBJECTIVE: To compare the effects of different cryopreservation methods on the ultrastructure and viability of aminotic membrane and to seek the ideal cryopreservation method.
METHODS: Aminotic membrane separated from the fresh placenta was preserved respectively with deep-frozen cryopreservation and vitrification, and everyway was run for 3 and 6 months. Fresh aminotic membrane was used as control. The ultrastructure of aminotic membrane was observed by transmission electron microscopy, and the viability of aminotic membrane was assessed by microcomputer analysis system for biological oxygen consumption, and immunohistochemical staining combined with image analysis system was used for lactate dehydrogenase activity.
RESULTS AND CONCLUSION:After 3 and 6 months of crypreservation, the damage to the ultrastructure of aminotic membrane by vitreous cryopreservation was slighter than that of amniotic membrane cryopreserved at-80℃. Compared with the fresh aminotic membrane, the gray value of lactate dehydrogenase and partial pressure of oxygen were significantly decreased in the cryopreserved aminotic membrane by deep-frozen cryopreservation at 3 and 6 months (P < 0.05) and by vitreous cryopreservation at 6 months (P < 0.05), but there was no statisticaly significant difference in the change rate of oxygen partial pressure and the gray value of lactate dehydrogenase between the fresh aminotic membrane and the cryopreserved aminotic membrane by vitreous cryopreservation at 3 months. The present study led to the conclusion that vitreous cryopreservation protocol alows to not only maintain the integrity of AM, but also to preserve the viability of the cels. So the vitreous cryopreservation is superior to the deep-frozen cryopreservation for cryopreservation of aminotic membrane.
