BACKGROUND:Pedicle screw implantation is a common method to repair many kinds of diseases of the lower cervical spine. Three-dimensional (3D) reconstruction visualization system can be used in order to improve the accuracy of the implant and improve the prognosis.
OBJECTIVE:To investigate the effect of 3D reconstruction visualization system on the accuracy of cervical pedicle screw implantation.
METHODS: The clinical data of 89 patients with cervical spine dislocation, who underwent cervical pedicle screw implantation, were analyzed retrospectively. Patients were divided into control group (46 cases) and observation group (43 cases) according to the navigation method. Patients in the control group underwent C arm X ray two dimensional navigation. Patients in the observation group underwent three-dimensional reconstruction visualization system navigation. Intraoperative placement time was observed, and the accuracy of screw placement was assessed in both groups. The cases were folowed up for 12 months, and the adverse events were recorded and compared.
RESULTS AND CONCLUSION: (1) Intraoperative implantation time was shorter in the observation group than in the control group, but no significant difference was found (P> 0.05). (2) Accuracy rate: There were no three types of nail cases in the observation group, and the accuracy rate was 93% (40/43). In the control group, two cases affected three types of nailing, and the accuracy rate was 81% (37/46). The accuracy rate was significantly higher in the observation group than in the control group (P < 0.05). (3) Postoperative folow-up: None suffered from nerve tissue injury to vertebral artery, blood vessel and spinal cord. The screws of the two groups were in stable condition, without screw breakage or loosening. (4) Results suggested that in lower cervical pedicle nail implantation, 3D reconstruction navigation system can effectively improve the accuracy of screw placement, and does not increase nailing time or lead to adverse events. It is a safe and effective navigation mode.

Objective To explore the clinical value of the duplex ultrasonography (duplex US) for evaluating the re-stenosis after peripheral arterial bypass grafting. Methods Eighty prosthetic grafts of sixty-three patients with femoral-pop-liteal arterial bypass grafting were follow-up regularly by duplex US. They were divided into non significant stenosis group (n=56), the significant stenosis group (n=15) and occlusion group (n=9) according to the tube diameter and arterial blood flow-ing parameters, which changed postoperatively. The diagnostic results were compared and analyzed between duplex US and digital subtraction angiography (DSA). The peak flow velocity of middle grafts (MG) to 40 cm/s was defined to evaluate risk of graft occlusion. Results The diagnostic coincidence rate of duplex US and DSA for grafts stenosis classification was 90%. The diagnostic sensitivity of duplex US to grafts stenosis was 91.7%, and the specificity was 92.9%. The positive pre-dictive value was 84.6%for grafts stenosis, and the negative predictive value was 96.3%, the false positive rate was 16.7%, and the false negative rate was 8.3%. The grafts occlusion rate was higher in MG<40 cm/s group than that of MG≥40 cm/s group. Conclusion There was a good consistency with Duplex US and DSA for the diagnosis of peripheral artery bypass graft restenosis. Duplex US showed characteristics of non-invasive, simple and easily accepted by patients.

Objective To compare the pharmacodynamics of rocuronium intermittently administered according to body surface area and real body weight and individual differences. Method Forty-two patients undergoing elective surgery under general anesthesia were enrolled into the body surface area group (BSA group) and the real body weight group (RBW group), with 21 patients in each group. The patients in the two groups were induced with 2ED95 of rocuronium according to body surface area and real body weight (16.64 mg/m2 in BSA group; 0.6 mg/kg in RBW group). Whenever T1 recovered to 10%, a dosage of 0.5ED95 was administred repeatedly for 30 min before the end of the operation. The time of neuromuscular blockade and recovery of muscle relaxation were recorded, and the dosage of rocuronium was also recorded. Results No significant difference in each index of neuromuscular block time-effect was found between the two groups (P > 0.05). The single dosage and maintainance amount of muscle relaxation were less in the BSA group than that in RBW group (P < 0.05). Compared with the RBW group, the single dosage, dosing intervals, pharmacological duration and the time TOFr recovered to 0.7 between the different individuals were less in the BSA group (P < 0.05). Conclusion The intermittent administration of rocuronium can maintain the same clinical efficacy according to body surface area as that according to real body weight , with significantly less dosageand reducing the differences of individuals in blockade time-effect of muscle relaxation.

Methods Compounds were isolated by repeated silica gel chromatography and purified on Sephadex LH-20 and structures were determined by spectral analysis. Results Cypritibetquinones A and B were isolated from the ethyl acetate residue and their structures were determined as 7-hydroxy-2-methoxy-1, 4-phenanthraquinone ( 1 ) and 7-hydroxy-2,10-dimethoxy-1,4-phenanthraquinone ( 2 ), respectively, by extensive spectral analyses. Conclusion Cypritibetquinones A and B are two new phenanthraquinones.

Objective To detect the changes of interleukin-18 (IL-18) in plasma of trauma patients and evaluate their value in early warning of organ dysfunction. Methods A prospective study was carried out in 54 trauma patients admitted in from March 2001 to September 2002, which were divided into low injury severity score(ISS) group (Group L-ISS) and high ISS group (Group H-ISS). ELISA was applied to measure the level of IL-18 of blood samples that were collected on arrival, at days 4, 7 and 14 following admission. In the meantime, IL-18 level of plasma samples from patients with systemic inflammatory response syndrome (SIRS), sepsis and multiorgan dysfunction syndrome (MODS) was retrospectively analyzed so as to calculate the critical value of IL-18 in predicting organ dysfunction. Results After trauma, IL-18 concentration of plasma reached peak at days 4 and 7, and decreased gradually at day 14, which was significantly related to SIRS, sepsis and MODS, respectively. The IL-18 level was high relatively in plasma from patients with organ dysfunction. The higher IL-18 level in plasma within seven days after trauma indicated the severer organ dysfunction. Conclusion IL-18 is sensitive in early warning of organ dysfunction after trauma.
