Objective To evaluate the accuracy of 3D-CT navigation in guiding pedicle screw fixation in the thoracic spine.Methods Thoracic pedicle screw placement guided by 3D-CT navigation was performed on 24 cases,including 14 patients with thoracic spine fractures,6 thoracic tumors,and 4 scoliosis.CT data was input into the navigation system,and point-matching test was chosen.The optimal position,diameter,and length of the screw were set up using navigation stick after true-up.Then,the screw was placed dynamically in a stereo way according to navigation plan.After the operation,the position of the pedicle screw was assessed with CT using the Rampersaud grading system.Results Under the guidance of 3D-CT navigation,a total of 144 screws were successfully fixed into the 24 patients.According to the Rampersaud grading system,136 of the screws were at grade A(94.4%),6 at grade B,1 grade C,and 1 grade D.No postoperative injury of the nerve or spinal cord was observed.Of the patients,22 were followed up for a mean of 8 months(range,6-14 months).During the follow-up,no loose or breakage of the screw was detected by X-ray and CT.No delayed spinal cord injury was found.Conclusions The thoracic pedicle screw placement can be accurately guided by 3D-CT navigation.

BACKGROUND: The early symptoms of amyotrophic lateral sclerosis (ASL) are usually located at a certain part of the body, and are similar to the clinical manifestations of cervical spondylotic myelopathy (CSM). However, their treatment and prognosis differ greatly. Therefore, multiple-part electromyography and electroneurography possess an important value of reference, particularly electromyography of thoracic paraspinal muscles can be used as an objective parameter for differentiation between ASL and CSM.OBJECTIVE: To investigate the electrophysiological changes in ASL and CSM.DESIGN: A retrospective clinical analysis.SETTING: Neurological Department of Second Hospital Affiliated to Jiangxi Medical College.PARTICIPANTS: Totally 30 inpatients and outpatients with ASL and 30 patients with CSM were selected from the Neurological Department of the Second Hospital Affiliated to Jiangxi Medical College between December 2001 and November 2004.METHODS: Totally 30 inpatients and outpatients with ASL as well as 30 inpatients and outpatients with CSM were subjected to routine electromyographic and electroneurographic examination. Routine electromyography examining three limb muscles + sternocleidomastoid + thoracic paraspinal muscles intended to observe the spontaneous potential at resting stage, time limit and wave-amplitude of motor unit potential, and recruit-ment phase during energetic contraction. Electroneurography was used to detect motsr conduction velocity and sensory conduction velocity,as well as the terminal latency and wave-amplitude of motor evoked potential.limb muscles, sternocleidomastoid and thoracic paraspinal muscles in paASL and SCM.RESULTS: Data of all the 60 patients entered the final statistical analysis.in patients with ALS and CSM, and were more severe in the former. The abnormality rate of spontaneous potential of thoracic paraspinal muscles reached 93.3% (28/30) as compared to 3.3% (1/30) in patients with CSM (P ＜ 0.001). The average time limit and abnormal increment of wave amplitude of motor unit potential were significantly different in patients with conduction velocity: The decrease rate of motor evoked potential amplitude of complex muscles was obviously higher in ASL than in CSM (75.6% and 86.7%, ~=7.25, P ＜ 0.01). So was the decrease rate of motor conduction sory nerve conduction velocity: It was not affected either in ASL or CSM.ALS and CSM, but the abnormality rate of spontaneous potential of thorography indicates that nerve conduction velocity was not affected in both playing decreased conduction velocity and wave amplitude than those with CSM.

Objective To explore the heme oxygenase-1 (HO-1) content of carbon monoxide (CO) levels and clinical significance of Mycoplasma pneumoniae infection in children.Methods 219 cases of mycoplasma pneumonia from October 2013 to June 2015 in our hospital were divided into two groups,which were non-asthmatic group (156 cases) and wheezing group (63 cases),and the wheezing group were divided into two groups according to the presence or absence of hypoxemia and mild asthmatic group (39 cases) and severe asthmatic group (24 cases).HO-1 content in the blood was measured by enzyme-linked immunosorbent assay,using dual-wavelength spectrophotometric determination of hemoglobin oxygen percentage of broken (COHb％),analysis of the differences between the groups.Results Children with blood COHb content wheezing group were (2.59 ± 0.40)％ and HO-1 levels were (1 813.24 ± 28.34)ng/L and non-respite group were significantly increased,it had significant differences between the two groups (P＜ 0.05).Group of children with severe wheezing COHb content were (3.63 ± 0.45)％ and HO-1 levels were (2 594.34±23.94)ng/L and mild wheezing group were significantly increased,it had significant differences between the two groups (P＜0.05).Positive correlation between blood COHb content and HO-1 levels were significantly (r=0.733,P＜0.05).Conclusion Mycoplasma pneumoniae infection in children with wheezing blood COHb content and HO-1 levels were significantly increased,and with wheezing exacerbation and showed an increasing trend,suggesting that CO and HO-1 may be involved in Mycoplasma pneumoniae infection in children in the pathogenesis of wheezing,should lead to clinical attention.

The lymphatic vessels and regional nodes of the nasopharynx in 70 foetuses and infant cadavers were studied with the method of injection of the lymphatics of the organ.There is a network of lymphatic capillaries in the mucous membrane of the nasopharynx, which drains into the submucous lymphatics. The latter join together to form a number of efferent ducts.The efferents emerging from the posterior wall of the nasopharynx end in the retropharyngeal lateral and medial nodes, or pass to the posterior aspect of the internal carotid artery and internal jugular vein and end in the upper deep cervical nodes lying deep to the tip of the mastoid.The lymphatics emerging from the lateral wall drain into the nodes right under the base of the skull anterior to the internal carotid artery and internal jugular vein, or descend to the jugulodigastric node, and the upper deep cervical nodes between the beginning point of the lingual artery and the bifurcate point of the common carotid artery.

ObjectiveTo investigate the curative effect of structural bone graft in treatment of high energy injury-induced complicated distal radius fractures combined with articular surface collapse and comminuted epiphyseal bone defect.MethodsThe study involved 38 patients with distal radius fractures (AO classification, type C3) treated from January 2007 to October 2010.The patients were treated with temporary Kirschner wire fixation to recover the wrist articular surface, distal radius length and palmar tilt angle at the greatest possibility.According to the form of the bone defects, the iliac bone taken from three layers of the cortical bone was embedded in the subchondral bone to support the bone graft, and a small amount of cancellous bone graft was collected to fill the articular surface collapse as much as possible for anatomical reduction of the articular surface, and anatomical form of the distal radius was reconstructed.Modified Sarmiento Gartland and Werley evaluation systems were used to evaluate the articular function recovery.ResultsThe follow-up lasted for 1-3.2 years, which showed no complications such as plate rupture or iatrogenic nerve blood vessels injuries.The fracture healing time was 15-22 weeks (mean 18.3 weeks).The wrist articular function in some patients obtained obvious improvement through functional rehabilitation training.According to the modified Gartland and Werley function evaluation systems, the curative effects reached excellence rate of 87％.During follow-up, there were two patients with high progressive loss in the height of the distal radius and two with articular surface collapse and severe carpal joint flexion and extension dysfunction.ConclusionsThe high energy injury-induced distal radius fractures with articular surface collapse and epiphyseal bone defect need recovery of the wrist articular surface, distal radius length and palmar tilt angle.Structural bone graft can effectively support the grafted bone and maintain the flatness of the radiocarpal articular surface, restore the anatomy of the distal radius and facilitate the functional recovery of the wrist.
