The result showed that levels of WBC,TB,DB,Glu and reticulocyte in six patients treated with β-lactam antibiotics were raised remarkably. DAT was strongly positive,but no RBC antibodies were detected in the plasma by IAT. The binding of red cells by monocytes or lymphocytes was great,and the hemolysis of red cells by alexin not appeared. After stopping above-mentioned β-lactam antibiotic administration,patient's WBC,TB,DB,and Glu levels returned to normal values.

结果发现：6例患者的临床治疗的药物都属于β内酰胺类；住院期间患者的WBC、TB、DB、Glu的检测结果出现异常，红细胞的DAT试验结果均为阳性，IAT试验结果均为阴性；将DAT阳性的红细胞进行补体结合实验时，结果为阴性；细胞涂片见部分红细胞表面有颗粒状物质附着，细胞培养见部分红细胞被白细胞识别、黏附；改用其它抗生素后，患者的上述化验指标恢复到正常值范围内，DAT试验结果转为阴性。

The basic approach of protecting people from being hurt or killed in an accident is to improve crashworthiness of vehicles. This paper starts with discussing theories and methods for vehicle passive safety design, which included experiential methods, analytic methods, multi-body dynamics methods, crash test methods and the finite element method. Emphasis will be paid to the basic FEM theories and algorithms of impact problems. Topics discussed include the governing equation, element discretization, hourglass control, time integration, material model, shell element algorithms and contact-impact algorithms. For more reliable simulation results, this paper then conducts study on how to accurately get material model parameters by combining the FEM method with experimental method, and develops relevant material test machine and parameter calculating software. Based on that, basic typical impact simulation and test validation study are conducted. On the basis of the above work, the paper studies the thin-shell structures'crashworthiness, which was affected by the following factors: spot-weld features, shell thickness, cross-section and pre-deformation. As to vehicle parts'crashworthiness, the paper conducts simulation study of designing energy-absorbing steering system and adaptive airbag system. A practical energy-absorbing steering wheel is designed as an example. In further depth research, the paper suggests several inverse quantificational methods for vehicle crashworthiness design based on the ideal crash characteristics. The above theories and methods are applied with good results through several practical vehicles' crashworthiness design and improvement.
