Different treatment regimens had been designed according to different classification.②Properly combined chemotherapy protocols reduced therapy intensity and decreased drug toxicities to patients with standard risk ALL.High dose methotrexate,instead of craniospinal radiation,had become effective phylaxis,and decreased the incidence of extramedullary relapse and CNSL (if indispensably,radiation dose was reduced).This measurement reduced radiation chemotherapy long term side effects and improved survival quality.

化疗方案合理组合在保证疗效的同时对ALL后期治疗降低强度，减少药物毒性，同时改进了庇护所预防措施———采用大剂量氨甲蝶呤，大大减少了髓外复发，使相当一部分患儿放弃以往颅脑预防性放疗，即使需要放疗者也降低了剂量，从而减少放化疗远期毒副作用，提高了生存质量。

OBJECTIVES: Both intramedullary and extramedullary internal fixation has been advocated for the treatment of subtrochanteric femur fractures.

目的：髓内与髓外固定都可以用来治疗股骨转子下骨折，本文旨在比较两种固定方法的临床疗效，确定二者那种疗效更好。

DATA SYNTHESIS: Three level I and 9 level IV studies were identified and used in the systematic review of outcomes for intramedullary and extramedullary fixation for subtrochanteric fractures. Three level I studies were used to calculate a pooled relative risk for failure of fixation with a 95% confidence interval.

数据合成：3个1级可信度研究和9个4级可信度研究被选择，用来分析髓内与髓外固定治疗股骨转子下骨折的疗效。3个1级可信度研究用来计算内固定失败的风险较低，其可信区间为95％。

Results Three cases of extramedullary myeloid sarcoma of the mouth mucosa all presented gingival enlargement.

目的 探讨髓外髓细胞肉瘤的临床病理学特征、诊断及鉴别诊断，以加深对该病的认识。

Thirty-two patients (mean age 41 ± 17 years) underwent cervical laminectomy without fusion for resection of an intradural tumor (18 intramedullary and 14 extramedullary).

硬膜内肿瘤切除（髓内18个、髓外14个）颈椎椎板切除后没有行融合术的32位病人（平均年龄41 ± 17岁）。
