Study the bioactivity of the n-HA/PA66 composite and the effects it would be to body's metabolism of calcium and phosphorus ion in vivo.(3) Study the osteo-conductivity and the ability to repair bone defect of the porous n-HA/PA66 composite and the feasibility use it as the scaffold of bone tissue engineering. Objects and Methods as follows: 1.To evaluate the biocompatability of nano-hydroxyapatite crystals and polyamide composite (n-HA/PA66) with the L929 cells.To proceed the morphological observation and take pictures of L929 cells after 1d,2d,4d,and 7d of co-cultured with extract of n-HA/PA66 ,and direct contact with n-HA/PA66.To determine light absorbtion value of every hole under 500 nm with enzyme linked immunity instrument after 1 d,2 d,4 d,and 7 d of contact of n-HA/PA66 extract with L929 cells,and direct contact with n-HA/PA66.In the meanwhile calculate the relative multiplication rate of cells,and evaluate them by six degree tests for cytotoxicity. To investigate the acute and chronic toxic reaction on the whole body induced by the new nano-hydroapatite crystals and polyamide composite(n-HA/PA66)after implanting in vivo and its effects on partial constitution of animal organs after implanting in vivo,and evaluate the potential and degree of subcuticular stimulation reaction.

本实验主要由以下三部分组成：一、n-HA/PA66 复合材料在动物体内、体外的生物相容性及生物安全性评价二、n-HA/PA66 复合材料植入动物体内的生物活性及近期对机体钙、磷代谢影响的实验研究三、网孔 n-HA/PA66 复合材料作为支架修复兔桡骨节段缺损的动物实验研究主要研究目标及方法如下：参照 GB/T16886.5-1997-ISO 10993-5：1992《医疗器械生物学评价细胞毒性试验体外法》之评价标准和要求，采用规定的 L929 细胞(小鼠结缔组织成纤维细胞)，分别经直接接触和材料浸提液与细胞共培养等方式对 n-HA/PA66 复合材料进行细胞毒性测试，采用细胞形态观察法观察两种细胞各组在 24h、48h、72h、5 天后各时相点的细胞形态学变化，并在显微镜下照相，从而对细胞与材料的生物相容性进行定性评价；同时采用细胞生长抑制法，以酶标仪定量测定评价各组 1，2，4，7 天 L929 细胞的相对增殖率，以定量测定并判别材料对细胞的毒性程度。

5Wu can not discover the synergistical pathway of prednisoneand the recipe of nourishing Yin and reducing Heat in the experiment 6Wu discovered many protein peaks unresponding protein in the experiment,wu need study deeply for future.

SELDI蛋白质质谱技术是一种新生的技术，用来研究SLE的报道不多，因经费问题实验的例数又较少，也可能是导致发现不了各肽类的相关性的原因，在以后的研究中可考虑扩大实验例数。 6在本实验中还发现大量找不到相应蛋白质的质荷峰，这些峰值有待进一步的研究。
