Résumé

BACKGROUND: The objectives of the present study were to investigate the reliability and outcomes of computer-assisted techniques in mandibular reconstruction with a fibula flap and verify whether the surgical navigation system was feasible in mandible reconstructive surgery. METHODS: Eight cases were enrolled in the computer assisted surgery (CAS) group and 14 cases in the traditional group. The shaping and fixation of the fibula grafts were guided by computer assisted techniques, which could be monitored with the BrainLAB surgical navigation system. The variation of mandible configuration was evaluated by CT measurement in the Mimics software, including the variation of length, width, height and gonial angle of the mandible. The 3D facial soft tissue alteration was also analyzed in 3D chromatogram by Geomagic software. RESULTS: All 22 fibula flaps survived. The mandibular configurations and facial contours had a better clinic result in the CAS group. The length, width, height and gonial angle of the reconstructive mandible were more similar to the original one. The Wilcoxon rank sum test analysis suggested significant differences in the measurements. The chromatographic analysis also visually showed superiority over the traditional group. CONCLUSIONS: The computer assisted surgical navigation method used in mandibular reconstruction is feasible and precise for clinical application. The contour of the reconstructed mandible and facial symmetry are improved with computer techniques.

Résumé

This study was purposed to explore the significance of tissue factor (TF), tissue factor pathway inhibitor (IFPI) and interleukin-1beta (IL-1beta) in the evaluation of development, curative effect and prognosis of AL patients. ELISA was used to detect the levels of TF, TFPI and IL-1beta in plasma of 20 healthy individuals and 24 newly diagnosed AL patients. All the three indications of patients were measured in different stages including pre-chemotherapy phase, at 72 hours after chemotherapy, complete remission phase. The results showed that as compared with normal control, levels of TF, TFPI and IL-1beta in plasma of AL patients during pre-chemotherapy phase were higher (p < 0.01); as compared with pre-chemotherapy phase, levels of TF, IL-1beta were elevated at 72 hours after -chemotherapy (p < 0.05). However, the levels of TFPI was much lower than that of 72 hours after chemotherapy (p < 0.01). 16 out of 24 patients got complete remission, there was no difference of TF, TFPI and IL-1beta between complete remission group and normal control group. It is concluded that the levels of TF, TFPI and IL-1beta in plasma can be used as the indicators for understanding clinical features, evaluating disease status and predicting prognosis in acute leukemia patients.
