分级

Macroporous adhesive resin column and Sephadex LH20 column were employed to separate and fractionate the crude extract and the structures of the main compounds were analyzed by HPLC-ESI-MS.

通过大孔树脂结合SephadexLH—20对芒果多酚粗提物进行分离纯化和分级制备，采用HPLC-ESI-MS对主要组分的结构做了初步分析。

BASIC STUDIES ON THE FRACTIONATION OF HIGH POLYMERS Ⅱ.

高聚物分级的基本研究——Ⅱ。

Changes in pain score, Frankel's classification, and blood parameters demonstrated a significant clinical improvement in all patients.

所有患者的疼痛评分、Frankel分级和血液参数等的改变，均显示出明显的临床改善。

On average, the Frankel grade improved 1 to 2 levels 3 months postoperatively.

术后3个月Frankel分级为B级1例，C级2例，D级3例，E级5例，平均提高1~2级。

Changes in pain score, Frankel's classification, and blood parameters demonstrated a significant clinical improement in all patients.

所有患者的疼痛评分、Frankel分级和血液参数等的改变，均显示出明显的临床改善。

Spinal injury was found in 4 cases, which Frankel C in one case and Frank D in 3 cases.

其中16例损伤平面以下无神经功能损害、无双下肢和大小便障碍；4例有不同程度的脊髓损伤，按Frankel分级：C级1例，D级3例。

25 patients were retrospectively analyzed of clinical manifestation and radiological feature, frankel scoring was compared before and after operation.

回顾性分析25例无骨折脱位型颈脊髓损伤患者的临床表现及影像学特点，根据损伤情况及影像学表现采取不同的手术方式治疗，并比较手术前后的frankel分级。

The average of 1.1 grade was increased according to the Frankel grading.

以Frankel分级作为脊髓恢复情况的判断标准。

By Frankel grading,11 cases improveⅡ grade,15 cases improveⅠ grade and 9 cases obtain no recovery.

结果 ：35例经 1年以上随访，按Frankel分级，改善 2级 11例，改善 1级 15例，无恢复 9例。

Results. Ninety-five of 107 cases (89%) obtained at least one level of neurologic improvement according to Frankel's classification and 86 cases (80%) became ambulatory after surgery.

结果：根据Frankle分级，107个病例中有（89％）95位患者至少获得了一个级别的神经功能提升。86位患者（80％）术后恢复行走能力。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
