Results show that E_c increased with the increase of energy input and the increase of the ratio of annular width to col - umn diameter .

结果表明，环形柱内连续相轴向扩散系数E_c随外界输入能量的增大而增大，随隙径比的增大而增大。

Conclusion The results from 1H-MRS suggest the distribution of neuronal loss in ALS , and 1H-MRS can be a quantitative measurement in the evaluation of UMN dysfunction in ALS .

结论1H-MRS技术可以检测ALS病人相关脑区NAA/Cr及Cho/Cr比值与正常人存在显著差别，提示ALS病人脑内确实存在着神经元的变性或缺失，同时表明1H-MRS技术可客观、定量地反映UMN的功能。

Object : To analyze whether the UMN could be used as a tumor marker in diagnosing lung cancer , and evaluating therapy effect and monitoring prognosis of lung cancer patients .

目的：通过检测健康人、肺部感染患者、肺癌患者尿中15种修饰核苷含量和分布的差异，为使修饰核苷成为一种广谱有效的肿瘤标记物应用于肺癌普查、评估疗效、监测预后，提供理论及实验依据。

Objective : To investigate the TMS-MEP changes in ALS and their correlations with clinical aspects . To assess the value of TMS-MEP in the diagnosis and UMN lesion evaluations of ALS .

目的：研究ALS患者TMS-MEP改变及与临床的相关性，了解其在ALS诊断和UMN损害评价中的作用。

The levels of 15 UMN in different pathologic patterns , including squamous cell carcinoma , adenocarcinoma , large cell carcinoma and small cell carcinoma were not significantly different ( p > 0.05 ) .

不同病理类型肺癌包括鳞癌、腺癌、大细胞肺癌、小细胞肺癌患者尿中15种修饰核昔在各病理类型肺癌之间含量无显著性差异（P>0.05），小细胞肺癌与非小细胞肺癌之间亦无显著性差异（P>0.05）。
