Spin-coating thin film has many aggregations and pinholes on its surface, TSPP LB films showed a relatively more flattened and condensed surface. The TSPP macrocycle lied vertical to the surface of the substrate, the long alkyl chains of the TSPP were not straight but lay on the substrate with a tilted angle about 52.3°.

在旋转涂得的薄膜上，TSPP分子以聚集体的形式分散分布，未聚集的TSPP分子形成的薄膜表面分布着大量针孔状的缺陷；LB膜表面平整均匀，TSPP分子的环平面紧密地排列在一起以羧基为支撑点垂直&站立&在基片平面上，分子侧链与基片平面成52.3°角排列。

In our research, through derivatization of stable calix[4]pyrroles, active substituting units were jointed on the calixpyrrolic skelecton. After acylamide and free radical transfer reaction, the preparation of new calix[4]pyrrole-bonded stationary phases were fulfilled. the separation abilities of them to inorganic and organic anions and medicines were exploited and new analytical methods were established. The separation mechanisms were discussed. At the same time, through using calix[4]pyrroles as additives in CZE to influence the electrophoresis of inorganic anions, the recognition mechanisms and influencing factors in supramolecular chemistry were also studied.

We also use rank sum test to analyse the differe- nce between the light pre-eclampsia group and the severe pre-eclampsia group (P=0.000),the early onset pre-eclampsia group and the late onset pre-eclampsia group (P=0.003). All of the results give the same conclude that the differences within the three groups are significant (P.05). Conclusion: We conclude that HLA-G proteins are normally expressed in invasive trophoblasts and HLA-G proteins expression is defective in most pre-eclamptic placenta.We propose that trophoblasts lacking HLA-G proteins are vulnerable to attack by the maternal immune system.

结论HLA-G分子特异性分布于胎盘EVCT的胞膜及胞浆中，生理妊娠组、子痫前期组间差异性存在表明其表达量的下降与子痫前期的发病相关；轻、重度子痫前期组间显著差异表明HLA-G分子表达量的下降与子痫前期病情严重程度相关，早发型重度子痫前期患者胎盘组织中HLA-G分子的表达明显低于迟发型组，提示我们HLA-G分子表达的降低程度还与发病早晚有关。
