Results: The prepared AmB-PBCA nanoparticle had a regular spherical or elliptic surface, with a mean diameter of (69.01±28.56) nm. The curve of standard AmB was linear within the range of 1.12-5.60μg/ml: D405=0.1634c+0.0066 (r=0.9993). The average recovery of AmB-PBCA-NP was 99.93%, showing the solution of AmB-PBCA-NP was stable within 12 h. The nanoparticles showed a sustained drug release in vitro within 24 h. The optimized recipe was: DextranT-70 stabilizer without sodium deoxycholate, with a mean encapsulation rate of 56.10% and a drug loading rate of 82%.

结果：制备的AmB-PBCA-NP外观呈圆或类圆形，平均粒径(69.01±28.56)nm，分散均匀；AmB标准品在1.12~5.60μg/ml范围内的线性回归方程为：D405=0.1634c+0.0066，r=0.9993，AmB-PBCA-NP的平均回收率为99.93%，其溶液在12h内稳定性较好；体外释放实验表明24h体外释放具有一定的缓释性；实验发现最优化的处方为稳定剂采用DextranT-70，且不加助溶剂脱氧胆酸钠，其包封率及载药量均比较高，分别为56.10%、82%。

Results: Regression equation of standard curve was A=151.33+87136x (r=0.9999), and linear range was between 0.0418 and 0.2508μg; the average recovery was 99.4%. The results of the tissue distribution demonstrated that harmine levels in stomach, lungs, liver, brain and heart in the emulsion group were higher than those in the suspension group, with the highest conc entration in stomach.

结果：方法学考察表明，标准曲线回归方程为A=151.33+87136x（r=0.9999），线性范围0.0418～0.2508μg，平均回收率99.4%；小鼠体内试验显示，harmine乳剂组在胃、肺、肝、心等脏器中的药物分布均高于混悬液组，且胃内harmine水平大大高于其他脏器，并在较高浓度维持较长时间。

The index system was first set up, which reflected the economy, society, resources and environment conditions in the district. Then, factorization method was employed by using the software SPSS to obtain comprehensive index numbers. The linear regression method and fuzzy mathematics method were used to compute the coordination degree of economy, society, resources and environment. Finally, on the basis of the status of comprehensive evaluation indexes and coordination degree of the district, the main problems in the sustainable development of Beibei District were found out and some suggestions were also proposed.
