The preparative purification of liriodendrin from Sargentodoxa cuneata using macroporous resin combined with crystallization process was evaluated. The properties of adsorption/desorption of liriodendrin on eight macroporous resins were investigated systematically. X-5 resin was selected as the most suitable medium for liriodendrin purification. The(More)
Mitotic arrest defective protein 2 (MAD2) gene plays a central role in the mitotic checkpoint. Elevated MAD2 expression was observed in a number of human malignancies; its role in the development of hepatocellular carcinoma is still not understood and is controversial. The purpose of this study was to investigate the clinicopathologic significance of MAD2(More)
With the well-developed theory and methodology of landscape security pattern, and by the analysis of natural, biological, and cultural processes, it's possible to judge and plan the landscape security pattern of definite ecological process, i. e., to maintain the minimum ecological land use of this ecological process both in pattern and in area, which is of(More)
A HPLC coupled with evaporative light scattering detection method had been developed for the simultaneous determination of 3,4-dihydroxyphenylethyl alcohol glycoside, salidroside, chlorogenic acid, and liriodendrin in the stem of Sargentodoxa cuneata. With a C18 column, the analysis was performed using acetonitrile and 0.2% formic acid aqueous solution as(More)
OBJECTIVE To investigate the effect of modified Xiaochaihu Decoction (, MXD) on transforming growth factor-β1/Sma- and Mad-related proteins (TGF-β1/Smads) signaling pathway in rats with chronic pancreatitis (CP) induced by dibutyltin dichloride. METHODS Thirty healthy male Wistar rats were randomly divided into the normal control group, CP group and(More)
