目的:探讨氢质子波谱(proton magnetic resonance spectroscopy,~1H-MRS)在脊髓小脑型共济失调3型/马查多–约瑟夫病(hereditary spinocerebellar ataxias 3 and Machado-Joseph,SCA3/MJD)诊断中的价值,同时探讨其与临床病程评分之间的...目的:探讨氢质子波谱(proton magnetic resonance spectroscopy,~1H-MRS)在脊髓小脑型共济失调3型/马查多–约瑟夫病(hereditary spinocerebellar ataxias 3 and Machado-Joseph,SCA3/MJD)诊断中的价值,同时探讨其与临床病程评分之间的联系。方法:SCA3/MJD起病患者、SCA3/MJD未起病患者及年龄匹配健康志愿者进行~1H-MRS检查,经数据后处理获得N–乙酰天门冬氨酸(N-acetylaspartate,NAA),肌酸(creatine,Cr),胆碱(choline-containing compounds,Cho),肌醇(myo-inositol,m I)值及NAA/Cr,Cho/Cr,m I/Cr比值。将以上数据进行对比研究;同时对于SCA3/MJD起病患者进行国际协作共济失调评估量表(International Cooperative Ataxia Rating Scale,ICARS)及共济失调等级量表(Scale for the Assessment and Rating of Ataxia,SARA)评估,计算NAA/Cr,Cho/Cr,m I/Cr比值与临床评分之间的相关性。结果:SCA3/MJD起病患者在桥脑及齿状核的NAA/Cr值较正常对照组明显减低。SCA3/MJD起病患者小脑齿状核NAA/Cr值与ICARS评分有明显相关性。结论:SCA3/MJD的病变主要位于小脑及脑干,ICARS评分与小脑病变的程度有相关性,能较好地反映临床表现的轻重程度。~1H-MRS对于SCA3/MJD的诊断有一定的应用前景。展开更多
目的:探索慢性腰痛病人利兹神经病理性症状和体征疼痛评分(leeds assessment of neuropathic symptoms and sign,LANSS)与疼痛强度的关系。方法:(1)三家研究中心(北京大学人民医院、中日友好医院和南京军区南京总医院)入选的慢性腰痛病...目的:探索慢性腰痛病人利兹神经病理性症状和体征疼痛评分(leeds assessment of neuropathic symptoms and sign,LANSS)与疼痛强度的关系。方法:(1)三家研究中心(北京大学人民医院、中日友好医院和南京军区南京总医院)入选的慢性腰痛病人填写LANSS量表及疼痛数字评分量表(numerical rating scale,NRS)。(2)使用spearman相关分析评价LANSS量表评分与疼痛强度的关系。结果:入组2115例慢性腰痛病人,总合格率为90.0%,调查对象平均年龄为50.1±15.6年,合格病人中男778例,女1125例。LANSS评分中值随疼痛强度的增加有一定的增长,但是两者的spearman秩相关系数小于0.4,且LANSS量表各项评分与疼痛强度的spearman秩相关系数均小于0.4。结论:中文版LANSS评分随疼痛强度的增加有一定的上升趋势,但是两者并无相关性。展开更多
