Objective To investigate the molecular mechanisms for the development of cardiac hypertrophy in hypertension,the present study provided the differential protein expression analysis of hypertrophied heart at differ- ent stages in spontaneously hypertensive rats (SHR).Methods The profiles of protein expression of left ventricu lar myocardium in SHR and its normotensive control Wistar-Kyoto (WKY) rats at the age of 4 and 20 weeks were analyzed with two-dimensional gel electrophoresis (2-DE) in combination with matrix assisted laser desorption ioniza- tion-time of flight (MALDI-TOF-TOF) mass spectrometry.Results Although the blood pressure of SHR was normal at 4 weeks age,hypertrophy of the left ventricle had already developed.The expression pattern in the hy- pertrophic myocardium was found 27 modulated proteins,20 of which were identified.These proteins are involved in reactions of energy metabolism,mitoehondrial oxidative phosphorylation and oxidative stress,etc.The expres- sion of 13 proteins was significantly changed in SHR rats at early stage prior to the development of sustained hyper- tension,while the expression changes of other 7 proteins occurred only at late stage in SHR rats when the blood pressure was significantly elevated.Conclusions lncrease in glycolysis and decrease in oxidation of fatty acid and glucose was shown in the hypertrophied myocardium from early stage in SHR prior to the development of hyperten sion.The significant changes in protein expression of the mitochondrial electron transport chain and antioxidative molecules support the hypothesis that oxidative stress promotes and accelerates the development of hypertensive car- diac hypertrophy.

The aim of this study is to compare the contents of five types of anthraquinones which mainly includes chrysophanol, physcion, emodin, rhein and physcion and phenolic acids in ten different processed products from Rheum officinale, and to investigate the effect of different initial processing method on the contents of anthraquinones and phenolic acids. Principal component analysis (PCA) was carried out by SPSS software to evaluate the quality of different processed products from Rh. officinale. In conclusion, the contents of anthraquinones in different processed products from Rh. officinale assume the certain regularity. Whether fresh-cut Rheum officinale Bail and how to dry it are derectly effect the contents of anthraquinones and phenolic compounds. The content of anthraquinones in rheum officinale of drying is obviously higher than smudging, and was more abundant in branch root than tap roots. Rh. officinale of drying which growed in Fengjie gained the highest score in PCA. Meanwhile, the procedure of wetting also help to increase the content of anthraquinones and decrease the content of phenolic acids.
