Objective To investigate the changes of vertebral-basal artery and regional cerebral blood flow(rCBF) in patients with olivopontocerebellar atrophy(OPCA).Methods 10 patients with OPCA were examined by digital subtraction angiography(DSA) and single-photon-emission-computed tomography(SPECT),and compared with the control group(patients with vertigo or transient ischemic attack).Results In OPCA group,there were 5 cases with small vertebral artery(50%),4 cases with single vertebral artery(40%),9 cases with small and little vessels(90%),10 cases with poor stain in later arterial phase(100%) could be seen by DSA.The lower rCBF in cerebellum and brain stem were seen in 8 cases(80%)by SPECT.In control group,there were 3 cases(15%),4 cases(20%),4 cases(20%),3 cases(15%) and 7 cases(35%) respectively.There were significant differences between the two groups(all P

Objective To investigate the possibility and accuracy of predicting malignant middle cerebral artery infarction (mMCAI) with bedside electroencephalography (EEG). Methods Thirty-five patients with massive hemispheric infarction (MHI) underwent bedside EEG monitoring within 48 h of onset. The EEG indicators were interpreted blindly, and the clinical, laboratory and imaging parameters were analyzed. The patients were divided into mMCAI group and non-mMCAI group according to whether they had occurred mMCAI or not within 7 days of onset. The differences of EEG indicators, clinical, laboratory and imaging parameters between the 2 groups were compared. When the parameters of significant difference and statistical significance appeared the odds ratio (OR) of occurring mMCAI were analyzed, and their accuracy of predicting mMCAI was calculated. Results Of the 35 patients with MHI, 20 were in the mMCAI group and 15 were in the non-mMCAI group. There were significant differences in the EEG indicators (infarction on the contralateral side, including disintegration of occipital α rhythm, generalized slow-wave, dominant frequency wave low amplitude, regional attenuation without delta [RAWOD]pattern, and absence of EEG reactivity), clinical parameters (nausea accompanied with vomiting), and imaging parameters (the infracted area more than the entire MCA territory, and midline shifting 3 to 5 mm at the level of septum pellucidum) between the 2 groups (P < 0. 05). Of those, the risk of mMCAI was the highest in patients with disintegration of occipital a rhythm on the contralateral side of infarction (P = 22. 67, 95% CI 3. 89-132. 10). The sensitivity of predicting mMCAI was 85. 0%, the specificity was 80.0%, the positive predictive value was 85.0%, and the negative predictive value was 80. 0%, which were superior to other EEG indicators and clinical or imaging parameters. Conclusions Bedside EEG indicators can early predict mMCAI, moreover, the predictive accuracy is superior to the clinical and imaging parameters.

BACKGROUND:Recently, the clinical repair methods of irregular wound on fingers primarily include local pedicled flap and free mini-flap of upper extremities or lower extremities.
OBJECTIVE:To discuss the application of free mini-flap derived from upper limb in repairing the wound on fingers.
METHODS:From December 2010 to February 2014, 12 patients with irregular wounds on 12 fingers were selected from Department of Traumatic Orthopaedics and Hand Surgery, First Affiliated Hospital of Guangxi Medical University, China. The size of wounds ranged from 1.5 cm × 2.0 cm to 3.0 cm × 4.5 cm with different degrees of bone or tendon exposure. After the debridement, 12 patients were treated by free mini-flaps of upper limb. The donor sites were directly sutured.
RESULTS AND CONCLUSION:Among the 12 patients, al the wounds at recipient and donor sites were healed at stage I, and the free mini-flags survival completely. Al of patients were fol owed up for 3-6 months (average 4.5 months). Free mini-flags had good appearance and needn’t undergo secondary trimming. The active motion of fingers was improved dominantly. According to the criteria of Hand Surgery Association Society of Chinese Medical Association Society for the function evaluation of upper limb, three cases were excellent, eight were good, and only one was bad. The excellent and good rate was 91%. Free mini-flaps of upper limb are an ideal method for repair of wounds on fingers. It has no injury to normal tissue in hands, donor site is very secluded, and the short-term curative effect is good.

Objective To compare the difference in pharmacokinetics characteristics of vancomycin in cerebrospinal fluid between administration by continuous infusion and interim infusion.Methods Twenty postoperative patients in the Department of Neurosurgery of Beijing Tiantan Hospital, Capital Medical University admitted into intensive care unit (ICU) to receive vancomycin for prophylaxis of intracranial infection were enrolled, and they were randomly distributed to a continuous intravenous infusion group and a interim intravenous infusion group, each group 10 cases. In continuous intravenous infusion group, the patients received a loading dose of vancomycin (15 mg/kg) by continuous intravenous pump infusion for 1 - 2 hours followed by 30 mg/kg vancomycin in a constant pump infusion rate for 24 hours; while in interim intravenous infusion group, the patients received 15 mg/kg vancomycin administered by intravenous pump infusion for 1 - 2 hours, once every 12 hours. The concentration of vancomycin in the cerebrospinal fluid at different time points was measured by two-dimensional liquid chromatography (2D-LC) method, the parameters of pharmacokinetics were calculated in the two groups, and the adverse reaction was observed.Results The comparison between the ratio of areas under the concentration-time curves (AUC) and minimum inhibitory concentration (MIC) of the continuous and interim groups showed no significant difference (19.7±14.0 vs. 16.1±6.4,P > 0.05). However, in the continuous intravenous infusion group, the drug concentration reached the peak value (0.96± 0.77)μg/mL at 12 hours, and later revealed a plateau concentration 0.91-0.93μg/mL for 12 hours; while in the intravenous infusion interim group, the drug concentration reached the peak value (0.92±0.47)μg/mL at 16 hours, in the later 2 hours declined to (0.84±0.45)μg/mL, and afterwards still had a tendency of persistent declination. In all the patients, no any adverse reaction related to the drug occurred.Conclusion Continuous intravenous infusion and interim intravenous infusion of vancomycin for the postoperative neurosurgical patients without intracranial infection have the similar efficacy of medication, but the former can achieve the peak concentration faster and later the fluctuation of drug concentration in cerebrospinal fluid is smaller than those in the latter.

Objective To find new way to reduce non-recurrent laryngeal nerve (NRLN) injuries by applying intraoperative neuromonitoring(IONM) to identify NRLN in thyroidectomy. Methods Records of 279 patients who underwent complex thyroidectomy by applying IONM to identify and monitor RLN from Mar. 2009 to Jan. 2010 were veviewed. We proposed the skills to identify and monitor NRLN and predict RLN varition through exploring vagus nerve and RLN before RLN dissection. Results 6 cases NRLN located on the right side were all accurately identified by IONM, thus no injury of NRLN occurred during thyroid operations. Conclusions NRLN is difficult to be predicted preoperatively and identified by naked eyes. The application of IONM to predict, identify and monitor NRLN could remarkably reduce the possibility of NRLN injury.

Objective To discuss the reasons of false judgments of localization of the rupture aneurysms and find the way to fix this problem in patients with multiple intracranial aneurysms. Methods The clinical data of 25 consecutive patients, who presented with their first spontaneous subarachnoid hemorrhage and had multiple intracranial aneurysms from 2003 to 2009 in our hospital, were analyzed retrospectively. The rupture aneurysms were determined according to Nehls' method that reported before, and the supposed responsible rupture aneurysms w0ere clipped within 48 hours after hemorrhage in all patients. More aneurysms that could not be accessed in the same surgical session were surgically terated later. Results The location of the rupture aneurysm was verified at the time of surgery in all 25 patients. The concordance rate of the prediction and the reality of the rupture aneurysm was 80% (20/25). Four patients ( 16% ) ,in whom the ruptured aneurysm was not correctly identified,rebled after surgery,and 2 patients died as a result of the rebleeding One patients had no clear diagnosis at the end. Conclusion In the reported cases, about 80% rupture aneurysms could be correctly diagnosed before treatment according to the CT and DSA examinations. If clear diagnosis couldn't be made,additional examinations should be considered, such as CTA or MRI. Rupture aneurysms must be confirmed during the operation and the other aneurysms should be checked to exclude additional responsible aneurysms in all cases.

BACKGROUND:Pedicle screw is the major instrumentation of surgery in thoracic spine. However, there have been few reports about pedicle morphology relevant to screw insertion tracts, and few reports comparing the normal adolescents and adolescent idiopathic scoliosis patients. OBJECTIVE:To compare the morphologic characteristics of the thoracic pedicle with regard to safe thoracic pedicle screw placement in normal adolescents and adolescent idiopathic scoliosis patients. METHODS: Thoracic pedicles of thirty-five normal adolescents and thirty-five adolescent idiopathic scoliosis patients were measured with three-dimensional reconstruction CT images. Measured parameters include (1) critical distance: the shortest distance from an entry point to the ventral cortex of the lamina. (2) Safe distance: the distance from the entry point to the tangent of the spinal canal at the medial wal of the pedicle. (3) Pedicle screw length. (4) Pedicle width. (5) Pedicle transverse angle. The dangerous area was defined as the distance between the critical distance and the safe distance. RESULTS AND CONCLUSION: The mean critical distance was (9.2±1.0) mm for the normal adolescents, and (9.4±1.2) mm for the adolescent idiopathic scoliosis patients. Safe distances were significantly less in normal adolescents (14.7±0.8) mm than that of the adolescent idiopathic scoliosis group (15.4±1.4) mm (P < 0.001). The dangerous area was (5.4±0.7) mm for the normal adolescents, which was significantly less than that of the adolescent idiopathic scoliosis patients (6.0±1.0) mm (P < 0.001). Pedicle screw length was (36.6±4.1) mm for the normal adolescents and (37.1±5.3) mm for the adolescent idiopathic scoliosis patients. Pedicle width was (5.8±1.2) mm for the normal adolescents and (5.7±1.7) mm for the adolescent idiopathic scoliosis patients. No significant difference in critical distance, pedicle screw length and pedicle width was found between the two groups (P=0.382, 0.135, 0.293). Pedicle transverse angle decreased gradualy from T1 to T12 in both groups. These results verify that pedicle morphology of many parameters is different between normal adolescents and adolescent idiopathic scoliosis patients, especialy in the apical area of the thoracic curve.
