Micronucleus test results exhibited that significant differences in micronuclear rates were determined between 0.4 mL bone cement and 0.4 mL microsphere-coated bone cement groups and negative control group, but no significant difference was detected among other groups. This revealed that this microsphere-coated bone cement leaching liquor did not show significant cell heredity toxic effects. Nevertheless, microsphere-coated bone cement in the high concentration and high dosage groups exhibited low toxic effects, mainly showing increased hemolysis rate and micronuclear rate. Thus, it was necessary to control the dosage and concentration of microsphere-coated bone cement.

微核实验结果显示除0.4 mL骨水泥组和0.4 mL微球骨水泥组的微核率与阴性对照组差异有显著性意义，其余各组差异无显著性意义，说明该微球骨水泥的浸提液无明显细胞遗传毒性作用，但是高浓度和高剂量组的微球骨水泥仍有较低的毒性作用，主要表现为溶血率和微核率的提高，因此在应用时要适当控制微球骨水泥的剂量和浓度。

Shim current calculation When shim coils are excited by appropriate current, they can generate correcting magnetic field to compensate the imaging magnetic field unhomogeneity. Based on the indirect calculation method, we proposed a novel iterative optimization algorithm to calculate shim current. Because there is a direct proportion relationship between FID signal and magnetic field homogeneity, we use the intensity of FID signal as feedback information to the calculation. Shim current can be worked out in less than 3 minutes. This satisfied the requirement that active shimming should be performed in real time.
