Objective To evaluate the value of pedicled fat and capsule-packed nerve root in operation of sacral canal cysts.Methods We collected the information of 14 cases of sacral canal cysts for operation in our department and analyzed the operation indications and skills as well as the prognosis.Results All the operations were performed with the help of the microscope and the electrophysiological monitor.The capsules were removed in 9 cases and wrapped in 6 cases,with the total resection rate of 64.3%.The clinical symptoms were improved markedly after the operation.Conclusion The operation with pedicled fat and the capsule-packed nerve root is valuable in treating sacral canal cysts because it can protect the nerve root and get lower recurrence rate.

Objective To observe the effect of pulmonary surfactant(PS) on lung function and ventilator parameters of neonatal respiratory distress syndrome(NRDS) in the advanced stage.Methods Twenty-eight infants with NRDS were given PS in one dose by endotracheal intubation on the left side,right side,feet high with head low,and level decub respectively.The dose of PS was 100-150 mg/kg each time,each posture slow note of the drug were required 1/4,out of the straw,hand-controlled ventilation,to reduce fluid loss,with the exception of a clear airway obstruction,within 6 hours after the administration not to shoot back suction,to give mechanical ventilation after the injection.Lung function parameters were also measured:pressure of oxygen in artery[p_a(O_2)],carbon dioxide partial pressure[p_a(CO_2)],the ratio of pressure of oxygen in artery and alveolar oxygen partial pressure[a/Ap(O_2)] and oxygenation index(OI) were determined.Ventilator parameters were determined:oxygen concentration(FiO_2),oxygen peak(PIP),end-expiratory positive pressure(PEEP) and mean airway pressure(MAP) were determined.These numerical data were analyzed and compared before and after treatment with PS.Clinical manifestations,thoracic X-ray changes,survival rate and incidence rate of complications were also analyzed and compared before and after PS therapy.Results p_a(O_2),a/Ap(O_2) showed significant upgrade and OI had a decrease after PS administration in comparison with those before PS therapy.The ventilator parameters(except for PEEP) acquired were also lower after drug administration than those in before drug therapy.There were significant differences in both stages(P_a90%,respiratory sound in 24 cases enhanced,the observation of chest film after 24 h indicated that,lesions in 21 cases improved significantly,5 cases took a favorable turn.The survival rate was 85.7%.The incidence rate of complication was as follows:pneumonia was 25%,patent ductus arteriosus was 10.7%,pneumorrhagia was 7.1% and intraventricular hemorrhage was 3.6%,respectively.Conclusion Respiratory function of NRDS is significantly improved by using PS in the advanced stage,and therapeutic effect is apparent.

ABSTRACT:Objective To compare the clinical effects of Zero-P and traditional titanium plate with cage in treating single level cervical spondylosis.Methods We retrospectively analyzed the clinical data of 28 patients with single level cervical spondylosis who underwent anterior cervical discectomy and fusion (ACDF)by traditional titanium plate with cage (group A,n=16)or Zero-P implant (group B,n=16)in our department between January 2012 and January 2014.The intraoperative blood loss,operation time,postoperative JOA scores,JOA recovery rate,NDI scores,and dysphagia incidence in both groups were measured and compared.The changes of the midpoint interbody height (IBH),the cervical Cobb angle of the surgical segment and the cervical Cobb angle of C2 and C7 vertebral body were measured on the standing lateral cervical spine X-ray.Results The operation time was significantly longer in group A than in group B (P < 0 .0 1 ), but there were no significant differences in intraoperative blood loss between the two groups (P>0 .0 5 ).The incidence of dysphagia was lower in group B than in group A.The two groups did not significantly differ in JOA score or JOA improvement rate during the same period after operation (P>0.05).The NDI score in group B was significantly lower than that in group A (P<0 .0 5 )at 1 month and 6 months after operation,but showed no significant difference in preoperative and 1 2 months after operation (P>0 .0 5 ).The midpoint interbody height in group B was significantly greater than that in group A (P<0 .0 5 )1 2 months after operation,but showed no significant difference one month after operation.The cervical Cobb angle of the surgical segment was significantly greater in group B than in group A (P<0 .0 5 )after operation, but there was no significant difference in cervical Cobb angle of C2 and C7 vertebral body between the two groups at various time points (P>0.05).Conclusion Zero-p and traditional titanium plate with cage have similar effects in treating single level cervical spondylotic myelopathy,and Zero-P system has the advantages of lower incidence of dysphagia after operation,shorter operation time and better recovery of postoperative cervical physiological structure.

Objective To study intraoperative neural electrophysiological monitoring applied in lumbosacral spinal cord tumor resection.Methods We retrospectively reviewed the clinical data of 212 patients undergoing lumbosacral spinal cord tumor resection with or without intraoperative neural electrophysiological monitoring in our hospital.The patients were divided into two groups:124 patients in the monitored group received intraoperative neural electrophysiological monitoring while 88 ones in the control group did not.The monitoring was performed by recording the cortical somatosensory evoked potential (CSEP),dermatomal somatosensory evoked potential (DSEP) and electromyography (EMG).The patients were followed up for 3-6 months and their postoperative outcome was analyzed.Results There were significant differences in the outcome (P <0.05),but no difference was found in the incidence of complications between the monitored group and the control group.The sensitivity of CSEP +DSEP+EMG was 100%,and the specificity was 55.9% in the former group.Conclusion Combined monitoring with CSEP,DSEP and EMG during lumbosacral spinal cord tumor resection is valuable in protecting the spinal nerve roots and ensuring better operation safety.

Objective To compare the modified expanding suspended laminoplasty and posterior pedicle screw fixation applied in lumbar intraspinal tumors and evaluate operation,complications,postoperative neurofunctional improvement and lumbar lumbar stability in the two groups.Methods We made a retrospective analysis of the clinical data of 1 14 cases of lumbar intraspinal tumors, including 66 cases of modified expanding suspended laminoplasty and 48 cases of posterior pedicle screw fixation.We compared the operation time,operation bleeding volume,and incidence of postoperative cerebrospinal fluid leakage in the two groups.We also analyzed the lumbar instability and spinal cord injury score standard by the Japanese Orthopedic Association (JOA)between the two groups at 3,6, 12,and 24 months after operation.Results The results of modified expanding suspended laminoplasty group were significantly better than those of posterior pedicle screw fixation group in operation time, operation bleeding volume and incidence of postoperative cerebrospinal fluid leakage (P < 0.01 ).The lumbar instability did not significantly differ between the two groups (P >0.05).At 3,6 or 12 months after the operation, changes in the increase of JOA score of the two groups had no significant difference (P > 0.05 ).However,24 mouths after the operation,the group of posterior pedicle screw fixation had significantly improved JOA score compared with that in the modified expanding suspended laminoplasty group.Conclusion Both the modified expanding suspended laminoplasty and posterior pedicle screw fixation have a favorable outcome of postoperative lumbar instability and neurofunction.And posterior pedicle screw fixation is superior to modified expanding suspended laminoplasty in improving neurofunction.

Objective To investigate the indications,surgical principles and advantages and disadvantages of microsurgery of intra-spinal tumor via the quadrant pathway.Methods We made a retrospective analysis of the clinical data of patients with spinal canal tumors treated via the quadrant pathway from October 2014 to July 201 5. Results Totally 1 6 patients were included.Their tumors were fully removed by microscopic resection,in which there were three epidural cases,twelve subdural extra-medullar cases,and one intra-medullar case.In terms of stage,there were three cases of cervical segment (C3 - C7 ),four cases of thoracic (T1 - T10 ),nine cases of thoracic and lumbar ones (T1 1 - S2 ). In pathology, there were nine cases of neurilemmoma, two cases of neurofibroma,four cases of meningeal tumor and one case of neuroepithelial cyst.The postoperative symptoms and signs of the patients were significantly improved,and no recurrence or complications occurred in the follow-up 2-10 months.Conclusion Quadrant pathway can be used in removing spinal epidural and subdural tumor,which is shorter than two vertebral segments in length,and the cross-sectional area is less than 2/3 of the spinal cord. However,surgery with extensive adhesion and intra-medullary lesions should be performed carefully,and the surgical techniques are more demanding and a longer learning curve is needed.

According to the World Health Organization (WHO), the basic sciences to support the human health are chemistry, physics and informatics. Chemistry is the base of pharmacy. Physics is the base of medical instruments and equipments (MIE). The diagnosis and therapy of diseases are relying on informatics. Therefore, as the fusion results of physics and medicine, medical physics is the creative source science of MIE. Among all diagnosis tools, medical imaging devices are the fastest-developed and the most-complicated MIE since Roentgen discovered X-ray which was quickly used in medical diagnosis in 1895. Among all treatment tools, the radiotherapeutical devices are the most-widely used and the most effective MIE for tumor treatments since Mrs. Courier found the nature radiation isotope Radium at the end of 19th century and began to use it in tumor therapy. Although the research and development (R&D) of so-complicated MIE need many subjects of science and engineering, the kernel science is medical physics. With the results of more than 50 years' development in developed countries, medical physics has defined its own field, which is the medical imaging physics and the radiotherapeutical physics. But, the definition has been expanded to be wider and wider. Therefore, we should pay more attention to the establishment of Medical Physics in China. In order to develop medical physics in china, the bases of R&D and clinical practice should be also built.
