BACKGROUND:Many previous retrospective smal-sample studies analyzed the short-term effects using pedicle screw placement to repair thoracolumbar fracture. Conclusions are relatively thin. Simultaneously, screw placement in the injured vertebra can further stabilize the vertebral body, and reduce screw and rod breakage and loss of correction. OBJECTIVE:To evaluate the long-term effects of pedicle screw placement fixation through the injured vertebra in the repair of thoracolumbar fracture. METHODS: From February 2010 to February 2012, 36 patients with thoracolumbar fracture, who were treated in the Department of Orthopedics, Guangzhou Panyu District Second People’s Hospital, were selected. They were treated by vertebral pedicle screw placement fixation. Height ratio of preoperative injured vertebral leading edge was averagely 36%. Kyphosis angle (Cobb angle) was 25°. Sagittal diameter of the center of the vertebral canal was 60%. Nerve function was classified according to Frankel classification: grade A, 2 cases; grade B, 6 cases; grade C, 10 cases; grade D, 9 cases; grade E, 9 cases. The height ratio of injured vertebra, kyphosis angle (Cobb angle), sagittal diameter of the center of the vertebral canal and Frankel classification of nerve function were compared before and after treatment. RESULTS AND CONCLUSION: The postoperative folow-up was 3-3.5 years. Pain was obviously aleviated postoperatively in 36 patients. Average height ratio of injured vertebra was 95%. Kyphosis angle (Cobb angle) was 3.5°. Sagittal diameter of the center of the vertebral canal was 96%. Significant difference was found in the above indexes before and after treatment (P < 0.05). Postoperative neurologic recovery: grade A in 1 case, grade B in 2 cases, grade C in 3 cases, grade D in 4 cases, and grade E in 26 cases. Postoperative fractures were reset. Complications such as breakage, loosing or correction loss were not found. These findings suggest that pedicle screw placement fixation through the injured vertebra in the repair of thoracolumbar fracture can make a satisfactory reduction, enhance the pressure stability of the spine, reduce the internal fixation of fracture and vertebral height loss, and have good long-term effects, indicating that the implant and host have good biocompatibility.

Objective To study the clinic characteristics and the treatment of acute pancreatitis ( AP) with and without hyperlipidemia. Methods The clinical data of 99 patients in our hospital from Jan. 2013 and Dec. 2013 were studied. Patients were divided into the hyper-lipidemic acute pancreatitis ( HAP) group and the control group ( AP without hyperlipidemia) . All the patients received standardized clinical AP treatment. The patient’ s condition, plasma biochemical index, treatment outcome, length of hospital stay, cost, and relapse were ob-served. Results The proportion of severe pancreatitis of HAP group (13. 6%) was obviously higher than that of control group (7. 8%). Blood sugar and uric acid of HAP group were significantly higher than that of control group, and the average blood sugar of HAP group reached to 171% of the control group. And the blood amylase of HAP group was only 44. 5% of that in the control group. One year recur-rence rate of HAP group (13. 6%) was significantly higher than that of control group (2. 6%) with a singnificant difference (P<0. 01). Conclusion It is suggested that hyperlipidemia condition has significant relations with the condition, performance and outcome of acute pan-creatitis.

Objective To study the effect of positive pressure ventilation extubation on arterial blood gas indexes of patients undergoing cardiac surgery. Methods 50 patients with orotracheal intubation after intracardiac opening operation under direct vision were randomly divided into the control group and the experimental group with 25 cases in each group. We used traditional method to pull out tracheal intubation in the control group. And positive pressure ventilation at 5 ~15 cm H2O during inspiration and pulling out tracheal intubation during expiration in the experimental group. The change of arterial blood PaO2, PaCO2, SaO2, pH and respiratory rate before and 1min、5min、10min after extubation was observed,and also the incidence rate of air tube obstruction was recorded. Results The change amplitude of arterial blood gas indexes of patients in the experimental group was obviously lower,and the length of change time reduced more than 50%. There were 4 air tube obstructions in the control group and there was no obstruction in the experimental group. The difference was statistically significant. Conclusions Positive pressure ventilation extubation can raise lung's compliance and improve oxygenation. And arterial blood gas indexes are more stable. It can decrease the incidence rate of hypoxemia and is a much more safe method.

Objective To investigate the changes in the dose requirements of rocuronium after right hemihepatectomy in donor of living donor liver transplantation. Methods Sixteen ASA Ⅰ patients of living donor liver transplantation, aged 21-49 yr, weighing 51-86 kg, scheduled for right hemihepatectomy, were enrolled in this study. Anesthesia was induced with iv midazolam and fentanyl, and TCI of propofol and rocuronium. Changes in adductor pollicis muscle were monitored by the train of four (TOF) stimulation. The patients were mechaincally ventilated after tracheal intubation when T1/Tc = 0. The target plasma concentration of rocuroniurn was reduced to 1.0 μg/ml after tracheal intubation and the concentration was regulated to maintain 0 < T1 ≤ 10%. Anesthesia was maintained with sevoflurane inhalation, TCI of propofol, intermittent iv injection of fentanyl. The infusion of rocuronium and inhalation of sevoflurane were stopped before the second time of cholangiography, the total time and amount of rocuronium administered and the recovery of muscle relaxation were recorded at this time (before hemihepatectomy). The infusion of rocuronium and inhalation of sevoflurune were rests-ted after right hemibepatectomy. After the peritoneum was closed, the infusion of rocuroniurn and inhalation of sevoflurane were stopped again, the total time and amount of rocuronium administered and the recovery of muscle relaxation were also recorded at this time (after hemihepatectomy). Results The amount of rocuronium administered was significantly reduced after hemihepatectomy compared with that before hernihepatectomy (P < 0.05). The amount of rocurunium administered after hemihepatectomy was (67 ± 13) % of that before hemihepatectomy. Conclusion Right hemihepatectomy can affect the metabolism of rocuronium in the donor of living donor liver transplantation.

Objective To study the dissociation of EDTA-dependent pseudo platelet aggregation by amikacin and to clarify the potential mechanism.Methods At different time points,two concentrations of amikacin (6.5 mg/ml and 10.0 mg/ml) were respectively added to EDTA-K2 anti-coagulated whole blood samples collected from two subjects with EDTA-dependent pseudothrombocytopenia.The aggregated-platelet dissociation was investigated by platelet count and microscopical examination.CD41,CD61,CD62p,PAC-1,and IgG on the platelets of the two patients and of a normal control were determined by the FCS under various conditions.Results When amikacin (6.5 mg/ml) was added within 1 hour after blood collection,it dissociated the EDTA induced platelet aggregation and the platelet counts returned to the normal level. The expression of CD62p,PAC-1,and PA-IgG on the platelets was decreased,yet the expression of CD41 and CD61 had no change.Conclusion Amikacin supplementation (6.5 mg/ml) within 1 hour after blood sampling may dissociate the aggregated platelets caused by EDTA. The mechanism may be associated that amikacin might inhibit the expression of CD62p,PAC-1,and PA-IgG on platelets. The amikacin supplementation would be an inexpensive,effective,and practical method to solve the platelet aggregation induced by EDTA.
