Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.

Objective: The purpose of our studies are gaining a better insight into the effect of genistein on mesangial cell"s phenotype change and ECM expression plus degradation under DN circumstances.We add genistein with different concentrations in high glucose cultured rat mesangial cells;feed DM rats with the single concentration genistein for different days;to explore the expression of SMemb,the mark of mesangial cell"s hypertrophy phenotype change;to examine the synthesis of Fn as well as the change of the balance between MMP-2 and TIMP-l;to comprehend its effect on renal pathological changes of DM rats and some related factors;trying toexplore the possible mechanisms.Through these studies,we will have some information about the experimental value of genistein in DN field.
目的:为了研究金雀异黄素对DN环境下大鼠MC肥大表型转换标志物SMemb和ECM分泌及降解的影响,我们拟在细胞水平以不同浓度的金雀异黄素作用于高糖培养下大鼠MC,在动物水平以同一浓度的金雀异黄素作用于DM大鼠不同时间,观察细胞表型转换标志物SMemb、ECM主要成分Fn、ECM降解酶系统基质金属蛋白酶—2(MMP-2)/基质金属蛋白酶抑制剂—1(TIMP-1)表达的变化,同时观察金雀异黄素对DM大鼠肾脏病理及影响肾脏病进展的糖脂代谢紊乱的影响,并进一步探讨金雀异黄素发挥作用的可能机制;为明确金雀异黄素在DN治疗中的地位及意义提供实验依据。
