颈脊髓慢性压迫症的代谢组学研究

目的探讨应用磁共振波谱技术（magneticresonance spectroscopy,MRS）测量颈脊髓慢性压迫症患者脊髓代谢组改变的可行性,探讨脊髓代谢组学与脊髓功能的相关性。方法 2009年1月至2010年6月行减压手术的脊髓型颈椎病（cervical spondylotic myelopathy,CSM）患者13例作为实验组,男8例,女5例;年龄37～84岁,平均58.2岁。术前进行神经系统检查、神经功能评价（JOA评分）和MRS检查,将感兴趣区放置在脊髓受压最严重部位的相邻节段。通过MRS测得以下代谢物的浓度：氮-乙酰天门冬氨酸（NAA）、胆碱（Cho）、肌酸（Cr）、乳酸（Lac）、肌醇（Ins）、谷氨酰氨（Glx）。15名健康志愿者为正常对照组,年龄和性别与实验组无明显差异,同样用MRS测得脊髓代谢浓度。计算以下代谢浓度的比值：NAA/Cr、Cho/Cr、Lac/Cr、Ins/Cr、Glx/Cr。结果实验组的NAA/Cr和Glx/Cr比正常对照组明显降低（1.18 vs 2.58,P=0.023;0.56 vs 1.25,P=0.008）。实验组的NAA/Cr与脊髓JOA评分呈正相关。但是两组其他代谢物浓度比值如Cho/Cr,mI/Cr,Lac/Cr的差异均无统计学意义。实验组患者中有4例出现乳酸峰,而对照组中无一例出现乳酸峰。结论 MRS可以定量测量颈脊髓的代谢组学改变。慢性颈脊髓压迫症患者的NAA/Cr和Glx/Cr较健康志愿者明显降低,说明神经元和轴突的减少和损伤。NAA/Cr与脊髓功能的相关性,提示有评价脊髓功能的临床价值,但尚需大样本的研究来证实。

Proton magnetic resonance chemical shift imaging (1H CSI)-directed stereotactic biopsy

INTRODUCTION: To add metabolic information during stereotactic biopsy target selection, the authors adopted proton chemical shift imaging (1H CSI)-directed stereotactic biopsy. Currently, proton single voxel spectroscopy (SVS) technique has been reported in stereotactic biopsy. We performed 1H CSI in combination with a stereotactic headframe and selected targets according to local metabolic information, and evaluated the pathological results. PATIENTS AND METHOD: The 1H CSI-directed stereotactic biopsy was performed in four patients. 1H CSI and conventional Gd-enhancement stereotactic MRI were performed simultaneously after the fitting of a stereotactic frame. After reconstructing the metabolic maps of N-acetylaspartate (NAA)/phosphocreatine (Cr), phosphocholine (Cho)/Cr, and Lactate/Cr ratios, focal areas of increased Cho/Cr ratio and Lac/Cr ratios were selected as target sites in the stereotactic MR images. RESULTS: 1H CSI is possible with the stereotactic headframe in place. No difficulty was experienced performing 1H CSI or making a diagnosis. Pathological samples taken from areas of increased Cho/Cr ratios and decreased NAA/Cr ratios provided information upon increased cellularity, mitoses and cellular atypism, and facilitated diagnosis. Pathological samples taken from areas of increased Lac/Cr ratio showed predominant feature of necrosis. CONCLUSION: 1H CSI was feasible with the stereotactic headframe in place. The final pathological results obtained were concordant with the local metabolic information from 1H CSI. We believe that 1H CSI-directed stereotatic biopsy has the potential to significantly improve the accuracy of stereotactic biopsy targeting.

The use of magnetic resonance spectroscopy in the subacute evaluation of athletes recovering from single and multiple mild traumatic brain injury

Abstract Advanced neuroimaging techniques have shown promise in highlighting the subtle changes and nuances in mild traumatic brain injury (MTBI) even though clinical assessment has shown a return to pre-injury levels. Here we use (1)H-magnetic resonance spectroscopy ((1)H-MRS) to evaluate the brain metabolites N-acetyl aspartate (NAA), choline (Cho), and creatine (Cr) in the corpus callosum in MTBI. Specifically, we looked at the NAA/Cho, NAA/Cr, and Cho/Cr ratios in the genu and splenium. We recruited 20 normal volunteers (NV) and 28 student athletes recovering from the subacute phase of MTBI. The MTBI group was categorized based upon the number of MTBIs and time from injury to (1)H-MRS evaluation. Significant reductions in NAA/Cho and NAA/Cr ratios were seen in the genu of the corpus callosum, but not in the splenium, for MTBI subjects, regardless of the number of MTBIs. MTBI subjects recovering from their first MTBI showed the greatest alteration in NAA/Cho and NAA/Cr ratios. Time since injury to (1)H-MRS acquisition was based upon symptom resolution and did not turn out to be a significant factor. We observed that as the number of MTBIs increased, so did the length of time for symptom resolution. Unexpected findings from this study are that MTBI subjects showed a trend of increasing NAA/Cho and NAA/Cr ratios that coincided with increasing number of MTBIs.     

Blood flow response in individuals with incomplete spinal cord injuries

STUDY DESIGN: Cross sectional comparison, control group. OBJECTIVE: To determine if incomplete spinal cord injured patients (SCI) have an abnormal blood flow response to cuff ischemia compared to able-bodied individuals (AB). SETTING: Academic institution. METHODS: Blood flow in five chronic incomplete SCI patients (C4-C5) and 17 able bodied individuals was measured in the common femoral artery using quantitative Doppler ultrasound (GE LogiQ 400CL) at rest and after distal thigh cuff occlusion of 2, 4 and 10 min to investigate whether blood flow or vascular control were different in SCI's and AB. RESULTS: Blood flow and the diameter of the common femoral artery at rest were similar in incomplete SCI and AB. Peak flow after 10 min of cuff ischemia (the highest found) was also comparable between incomplete SCI and AB. The half-time for recovery of blood flow to baseline after 2, 4 or 10 min of ischemia was 50% longer for incomplete SCI compared to the AB (P = 0.023). In addition, peak blood flow after 2 and 4 min of ischemia relative to the maximum, 10 min value (2/10 and 4/10 ratios) was lower in incomplete SCI compared to AB (0.65 +/- 0.06 vs 0.76 +/- 0.15, P = 0.029 and 0.75 +/- 0.10 vs 0.89 +/- 0.11, P = 0.014, respectively). CONCLUSION: This study demonstrated that incomplete spinal cord injured patients have impaired vascular control seen as a slower return to resting flow after cuff ischemia and reduced sensitivity to ischemia relative to maximum flow. However, incomplete SCI patients did not demonstrate impaired flow capacity as seen in complete SCI patients suggesting that smaller cardiovascular abnormalities are seen with incomplete versus complete SCI injury. Impaired vascular control may serve to limit exercise capacity and may contribute to increased cardiovascular disease. Impaired circulation could contribute to impaired muscle function and poor cardiovascular health in incomplete SCI's, although these findings need to be replicated in a study with more subjects.     

扩大半椎板切除术治疗颈脊髓损伤

OBJECTIVE: To treat cervical spinal cord injury (SCI) accompanied with narrowing spinal canal by expanded hemilaminectomy. METHODS: From 1995 January to 1998 April 51 patients of cervical SCI were treated by expanded hemilaminectomy. Spinal injury classified in to 3 types: no fracture-dislocation (39 patients) fracture dislocation at the lower cervical spine (11), and burst fracture (1). The types of SCI included central cord injury (18 patients) incomplete cord injury (19), and complete cord injury (14). MR imaging in 23 patients showed degenerative changes with normal intensity of the cord in 14 patients, multiple level hyperintensity in 3, cystic changes in 3, myelomalasia in 3, and cord brocken in 1. Expanded hemilaminectomy was performed in 24 hours in 3 patients, in 48 hours in 9, in one week in 2, after one week in 35, and after one year in 2. The left or right laminae were removed from C(7) to C(3) in 42 patients, C(3) - T(1) in 3, C(2) - C(7) in 2, C(3) - C(6) in 3 and C(4) - C(7) in 3. Hemilaminectomy was expanded lateral to the inner of apophyseal joint and medial to the inner lamina beneath the spinal process. RESULTS: Follow-up lasted for 1 year and 7 months. Six patients with complete cord injury had of the no recovery lower extremity but recovery of the brachialis and extensor radial longus. 12 patients of central cord injury had full recovery except intrinsic muscles of the hand (5). They operated were on 2 weeks after injury. 17 patients of incomplete cord injury recovered to Frankel IV. CONCLUSIONS: Expanded hemilaminectomy is indicated for patients of cervical SCI with narrowing spinal canal or without fracture dislocation. Best results can be obtained in patients of central cord injury, and incomplete cord injury. Even in complete cord injury, 1 - 2 forearm muscle may recover (24.8%), securing a pinch grip reconstruction.     

Midsagittal tissue bridges are associated with walking ability in incomplete spinal cord injury: A magnetic resonance imaging case series

Context: Following spinal cord injury (SCI), early prediction of future walking ability is difficult, due to factors such as spinal shock, sedation, impending surgery, and secondary long bone fracture. Accurate, objective biomarkers used in the acute stage of SCI would inform individualized patient management and enhance both patient/family expectations and treatment outcomes. Using magnetic resonance imaging (MRI) and specifically a midsagittal T2-weighted image, the amount of tissue bridging (measured as spared spinal cord tissue) shows potential to serve as such a biomarker. Ten participants with incomplete SCI received MRI of the spinal cord. Using the midsagittal T2-weighted image, anterior and posterior tissue bridges were calculated as the distance from cerebrospinal fluid to the damage. Then, the midsagittal tissue bridge ratio was calculated as the sum of anterior and posterior tissue bridges divided by the spinal cord diameter. Each participant also performed a 6-minute walk test, where the total distance walked was measured within six minutes.

Findings: The midsagittal tissue bridge ratio measure demonstrated a high level of inter-rater reliability (ICC?=?0.90). Midsagittal tissue bridge ratios were significantly related to distance walked in six minutes (R?=?0.68, P?=?0.03).

Conclusion/clinical relevance: We uniquely demonstrated that midsagittal tissue bridge ratios were correlated walking ability. These preliminary findings suggest potential for this measure to be considered a prognostic biomarker of residual walking ability following SCI.
