Objective To investigate the surgical technique and efficiency of the "Cave-in" 360°circumferential decompression for thoracic spinal stenosis(TSS)with ossification of posterior longitudinal ligament(OPLL).Methods From October 2005 to October 2009,26 TSS cases with OPLL were surgically treated,including 17 males and 9 females.Nineteen cases had upper thoracic spinal stenosis(T1-4)with OPLL,while 14 of them also had ossification of ligamentum flavum(OLF).All the other 7 cases had middle and/or lower(T5-12)TSS with both OPLL and OFL.All patients had severe spinal cord compression,and preoperative Frankel Grade was B in 6 cases,C in 13 cases and D in 7 cases.All these cases were surgically treated by 360° circumferential decompression("Cave-in" technique).Firstly,posterior wall was removed to decompress thoracic spinal cord.Secondly,the residual facets and pedicles were removed and posterior 1/3 of vertebral cancellous bones were cut along pedicles at 60° angle inclination to make a "culvert".Finally,the culvert walls were pressed to collapse and the OPLL blocks were removed to achieve ventral decompression.Pedical screw fixations were performed in all patients.Results All cases had immediate postoperative neurological improvement except 2 who experienced transient postoperative neurological deterioration for 13-27 days.At the end of 6-30 months follow-up,all these patients had neurological improvement.At the last follow-up,Frankei Grade was C in 2 cases,D in 15 cases and E in 9 cases.Conclusion This "Cave-in"360° circumferential decompression removes ventral and dorsal spinal compression from the posterior approach in TSS cases.It is a direct decompression procedure,which reduces the rate of postoperative paralysis.

[Summary] Traditional anterior thoracotomy surgery for thoracic idiopathic scoliosis has amount of disadvantages such as large trauma,postoperative pain,and pulmonary function decrease.Video-assisted thoracoscopic surgery (VATS),which is considered as an effective method for the treatment of idiopathic thoracic scoliosis,can avoid those disadvantages as compared with thoracotomy surgery.Common surgical procedures include anterior spinal release with intervertebral fusion and instrumentation through video-assisted thoracoscopic surgery (IVATS).This article reviewed the history,indications,contraindications,advantages,disadvantages and outcomes of VATS in the treatment of idiopathic thoracic scoliosis.

Objective To investigate the effects of carbon monoxide poisoning on the long-term cognition in elderly patients.Methods Totally 53 patients with carbon monoxide poisoning and 51 healthy persons at our Hospital from June 2005 to June 2008 were enrolled.Mini-mental state examination(MMSE) and activities of daily living(ADL) scale were utilized to evaluale the life quality of the elderly patients through a cross-sectional study on July 2011.Results MMSE score showed that the attention calculation score,delayed recall score,and total score were higher in control group (4.9±0.4,2.9±1.0,28.3±2.3,respectively) than in carbon monoxide poisoning group (4.5±0.8,2.6±0.6,25.5±3.5,respectively) (t＝3.138,3.607,4.802,all P＜0.05).ADL score of carbon monoxide poisoning group was 26.7±7.3,and that of the control group was 2.04±7.6 (t＝1.827,P＞0.05).Conclusions Elderly patients with acute carbon monoxide poisoning may cause long-term cognitive impairment with decreasing attention calculation and delayed recall.

To explore the role of cerebro-spinal flu id(CSF)glutamate and nitric oxide (NO) in the pathogenesis of neonatal hypoxic- ischemia encephalopathy (HIE), glutamate and NO in CSF were determined in 24 new born infants with HIE and 8 normal control infants, respectively. The results sh owed that the levels of glutamate and NO in CSF were significantly higher in the neonates with moderate and severe HIE than those in both of the control group an d neonates with mild HIE.There was an obviously positive relationship between le v els of glutamate and NO. It is concluded that glutamate and NO play an important role in the pathogenesis of neonatal HIE.

Objective To discuss the CT and MR imaging appearances and diagnostic value of spinal lymphoma. Methods Sixteen patients with pathologically proved spinal lymphoma (aged 8 to 63 years) were retrospectively reviewed. CT were performed in all 16 patients, and MRwere performed in 12 patients. Results Totally 65 vertebrae (cervical 15, thoracic 22, lumbar and sacrum 28) were involved. Multiple lesions were found in 11 patients. The characters of these lesions were osteolytic, osteogenic or mixed on CT. The signal intensity was hypo or iso on T1WI and iso or slightly hyper on T2WI. The extradural involvements were more extensive than that of the vertebrae both on CT and MR images. Conclusion Lesions of spinal lymphoma usually demonstrate various bone destructions on CT, and hypo or iso intensity on T1WI as well as iso or slightly hyper intensity on T2WI, tending to involve paraspinal or extradural space, and longitudinal involvements are often seen along the vertebral canal. MRI is more sensitive than CT in detecting spinal lymphoma lesions.

Objective To investigate the improvement role of aspirin combined with statins on carotid plaque of patients with cerebral thrombosis.Methods80 cases of patients with cerebral thrombosis in our hospital from May 2014 to May 2016 were selected, these patients were divided into aspirin combined with statins treatment group (combined treatment group, 40 cases) and single aspirin treatment group (single treatment group, 40 cases) two groups according to the treatment methods, the NIHSS scores, Barthel indexes, clinical curative effects, IMT, plaque areas of the two groups were statistically analyzed.ResultsThe NIHSS score of the combined treatment group was significantly lower (P<0.05), the Barthel index was significantly higher (P<0.05), the total treatment efficiency 95.0% (38/40) was significantly higher than the single treatment group 80.0% (32/40) (P<0.05), the IMT was significantly shorter (P<0.05), the plaque area was significantly smaller than the single treatment group (P<0.05).ConclusionAspirin combined with statins can more effectively improve the carotid plaque of patients with cerebral thrombosis than aspirin alone, so is worthy of promotion and use in the clinical.

Objective To investigate the CT and MRI features of Langerhans cell histiocytosis (LCH) with multiple spinal involvement.Methods The CT and MRI data of 13 patients with multiple LCH lesions in spine confirmed by pathology were retrospectively analyzed.All of 13 cases underwent CT examination (1 case underwent enhanced scanning) and 12 cases underwent MR examination (6 cases underwent enhanced scanning).Results In 13 cases,there were 8 cases of single central lesions invading the adjacent vertebrae and 5 cases of multiple central lesions.There were 19 core spinal lesions and 15 adjacent invading lesions in a total of 34 vertebrae lesions.Eighteen core lesions (18/19,94.74 ％) had different degrees and shape of vertebral compression.A total of 34 abnormal vertebrae were found in 13 cases by CT,which were manifested as osteolytic bone destruction.Eighteen cortical bones of 19 core vertebrae were incomplete,and a paravertebral soft-tissue masses were observed.There were 33 vertebrae lesions in 12 patients who underwent MR examination,including 18 core spinal lesions and 15 adjacent invading lesions.The lesions displayed equal,slightly lower or low signal on T1WI,slightly higher or high signal on T2WI and high signals on fat suppression sequences.A paravertebral soft-tissue masses were observed in 17 core spinal lesions (17/18,94.44％).Conclusion CT and MRI manifestations of spinal multiple LCH have certain characteristics.The level of diagnosis and differential diagnosis should be improved by deepen understanding of the disease image performance,but the diagnosis still depends on the pathology.

Objective To determine the ED50 of isoflurane and desflurane in the presence and absence of epidural lidocaine using BIS value 50 as the criterion (MACBIS50 ) .Methods Forty-eight ASA I - II patients (26 male, 22 female) aged 18-70 years were randomly divided into isoflurane group ( n = 24) and desflurane group ( n = 24).Each group was further divided into 2 subgroups: general anesthesia group(GA, n = 12) and combined general-epidural anesthesia (CGEA, n = 12) . Patients with body weight over 110kg or under 50kg were excluded. The patients were premedicated with intramuscular atropine 0.01 mg?kg-1 . In CGEA subgroup epidural anesthesia was performed at T5-6 before induction of general anesthesia. A catheter was inserted into the epidural space in a cephalad direction for 3cm. A loading dose of 10ml of 1.6% lidocaine with 1:200 000 adrenaline was given after test dose followed by 5 ml 1.6% lidocaine every 40-60 min. General anesthesia was induced with fentanyl 1 ?g?kg-1, propofol 0.5-1.0 mg?kg-1 and vecuronium 0.1-0.2 mg?kg-1 . The patients were intubated and mechanically ventilated (FiO2 = 100% , FGF = 2 L?min-1 , VT = 8-10 ml?kg-1, PET CO2 = 35 mm Hg) . Anesthesia was maintained with isoflurane or desflurane. The end-tidal concentration of isoflurane and desflurane was continuously monitored and BIS also. MACBIS50 was measured using up-and-down method. The initial concentration of anesthetic for isoflurane was 1.0% and for desflurane 5.0% . A steady state end-tidal concentration of isoflurane and desflurane was maintained for 10 min. When BIS value was 50 the anesthetic concentration for the next patient increased by the same amount. Results MACBIS50 of isoflurane in GA subgroup was 1.16% and in CGEA subgroup 0.77% . MACBIS50 of desflurane in GA subgroup was 5.18% and in CGEA subgroup 3.87% . There was linear correlation between BIS value and end-tidal concentration in each subgroup. Conclusion Epidural lidocaine significantly reduces the end-tidal concentration of isoflurane and desflurane for adequate depth of anesthesia. A linear correlation is maintained between BIS and end-tidal concentration.
