Objective To explore the sensitive blood plasma molecular markers in diabetic nephropathy (DN) .Methods Two-di-mensional fluorescence difference gel electrophoresis (2D-DIGE) was used to analyze early DN patients plasma (n=8) and normal plasma ,proteins that showed differential expression of a 1 .5 fold change were analyzed by MALDI-TOF/TOF mass spectrometry . Results 2D-DIGE maps of plasma proteins in patients with DN and normal plasma were established successfully .We validated 13 differentially expressed proteins detected by 2D-DIGE ,including complement component C3、complement component C4、apolipopro-tein E ,etc .Conclusion Proteomic analysis can objectively revealed the differences of protein expression between the two kinds of blood plasma .The 13 proteins might be the potential plasma molecular markers for the clinical diagnosis of diabetic nephropathy .

Objective To screen the sensitive plasma molecular markers in diabetic nephropathy ( DN) patients with kidney yang deficiency. Methods Two-dimensional fluorescence difference gel electrophoresis (2-D DIGE) was used to analyze the plasma which was sampled from 4 early DN patients with kidney yang deficiency and 4 healthy adult volunteers. Proteins that showed differential expression with an over 1.5-fold change were analyzed by MALDI-TOF/TOF mass spectrometry. Results Two-dimensional electrophoresis (2-DE) maps of plasma proteins in DN patients with kidney yang deficiency and healthy adults were established successfully. We validated 9 differentially expressed proteins, including complements C3 and C4, apolipoprotein E and ubiquitination factor. Conclusion Proteomic analysis by 2-D DIGE can objectively reveal the differences of plasma protein expression in DN patents with kidney yang deficiency and healthy adult volunteers. The obtained 9 proteins have potential to provide plasma molecular markers for the early clinical diagnosis and for the research of traditional Chinese medical patterns of DN.

[Objective] To develop a method for the determination of thiamazole content in Yingqi Ling Tablets. [Methods] High performance liquid chromatography (HPLC) was used. The chromatographic conditions were: C18 Gravity Column (4.6mm ? 250mm), methanol - water (10:90 ) as mobile phase, flow rate being 1.0mL/min and the detection wavelength at 258nm. [Results] The calibration curve was linear in the range of 0.16 - 0.64?g. The average recovery was 101.01% (relative standard deviation sr = 2.21%). Relative standard deviation of precision test was 1.04% and the content of the sample was 0.4841 mg per tablet (sR = 0.78%). [ Conclusion] HPLC is effective for the determination of thiamazole content in Yingqi Ling Tablets.

Objective To prepare Shichangpu Double Layer Tablets. Methods The release of the sustained-release layer (SRL) was used as the response parameters and uniform design with alterable levels was used to optimize the recipe of SRL of Shichangpu Double Layper Tablets. Fast-release layer (FRL) was made from water extraction by ultra-filtration. Results The dissolution kinetics of SRL could follow zero-order equation and FRL showed good prosperities for fast release in 10 min. Conclusion The in vitro release of SRL of Shichangpu Double Layer Tablets testifies the significant sustained release action and FRL disintigrates rapidly. The preparation technology of Shichangpu Double Layer Tablet is reliable and simple.
