The major symptoms of SLE are the following: butterfly shaped Malar rash particularly on cheeks, discoidal rash, Photosensitivity, regular oral ulcers, nonerosive Arthritis, Pleuritis or Pericarditis, renal disorder, neurologic disorder, hematologic disorder, immunologic disorder, Anti-nuclear Antibody Test positive. Patients who are present any four of above symptoms can be clinically classifi-ed as SLE patients.

SLE的主要临床徵候包含：脸上呈蝴蝶状分布的红斑、身体出现圆盘状红斑、对阳光过敏、经常口腔溃疡、多发性关节炎、胸膜炎或心包膜炎、肾功能障碍、神经系统异常、血球计数异常、免疫系统异常、抗核抗体（Anti-nuclear Ab，ANA）阳性；只要在以上11项中出现四项以上即符合SLE的诊断。

Results Stable drug-resistant SW1990/GZ cell strain was established by culturing with gemcitabine for 9 months. The morphology and growth characteristics of the cell strain changed remarkably. The cells shrinked and became rounder; its endoplasm expanded; granular substances increased; and the doubling-time was prolonged. Resistance of the cell line to gemcitabine, fluorouracil, adriamycin, and mitomycin significantly increased. The TrxR activity of the drug-resistant cells was increased markedly.

结果 药物培养9个月后，得到稳定传代的SW1990/GZ耐药细胞株；其形态学、生长特征等均发生了明显变化，细胞变圆、体积缩小、内质网扩张、颗粒样物质增多及细胞倍增时间延长；对吉西他滨、5-氟尿嘧啶、阿霉素和丝裂霉素的耐药性均显著增加；耐药细胞的TrxR活性也明显增高。

This study refers to the conditions of practical powder metallurgy manufacture process, and proceeds to experiments and gear precision measurements as well as investigation on the effects of two parameters, powders and pitch circle radius, on gear precision. The relationship between gear parameters and gear surface deviations was derived from the mathematical model for the involute helical gears and the analysis of gear surface deviations.
