OBJECTIVETo explore the relation of phlegm-stasis syndrome with insulin resistance and monocyte peroxisome proliferator activated receptor-gamma messenger ribonucleic acid (PPARgamma mRNA) expression in patients with coronary heart disease (CHD).

METHODSSixty patients with CHD were differentiated into three syndrome types, the non-phlegm non-stasis (NN) type, the phlegm congealing heart vessel (PC) type and the phlegm-stasis cemented (PS) type. Besides, 20 healthy volunteers were selected as the normal control. Levels of fasting plasma glucose (FPG) and fasting insulin (FINS) were determined and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated accordingly. The expression of PPARgamma mRNA in the peripheral monocytes was assessed by reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSLevels of FINS, HOMA-IR and PPAR-gamma mRNA expression in all CHD patients were higher than in the normal control (P <0.01, P < 0.05); comparisons of the three indexes between patients of different syndrome types showed that they were higher in PC type and PS type than in NN type (P < 0.05 or P <0.01), and the difference between PC type and PS type was significant (P < 0.05).

CONCLUSIONChanges of insulin resistance and PPARgamma mRNA expression in monocytes are possibly one of the mechanisms for the development of phlegm-stasis syndrome in CHD.

Febuxostat, as a xanthine oxidase inhibitor, is a classic anti-gout drug with significant therapeutic effects and good tolerability. The structures of febuxostat and its derivatives can be divided into two parts: a substituted phenyl ring and a five-membered or six-membered heterocyclic ring with a carboxyl substitution. This paper reviewed the research progress of febuxostat derivatives in recent ten years and classified the structure-activity relationships of various febuxostat derivatives. Exploring the action mechanisms and structure-activity relationships of xanthine oxidase inhibitors might be significant for the rational design and development of new anti-gout chemical entities.

The concentration of extract of traditional Chinese medicine (TCM) is one of the important unit operations that affect the quality of the pharmaceutical products. However, there are some problems to be solved. The concentration process has the shortages of relatively high temperature, relatively long time or low efficient, some losses of active and volatile ingredients, more operation steps, easy fouling and emission of waste water. In order to solve these problems, many new technologies and installations have been developed in the past thirty years, including suspension freeze-concentration, progressive freeze-concentration, single- or multi-effect evaporation with an external natural circulating flow, on-line preventing fouling evaporation with vapor-liquid-solid flow, reverse osmosis concentration, membrane distillation, osmotic distillation, macro-porous resin adsorption etc. The system of the extract of TCM is very complex. The extract includes water and alcohol extracts. The composition of TCM is made of active and inactive ingredients. Hence, it is necessary to master the features of every concentration technologies and installations, including their merits and demerits, flexibilities, degree of maturations of techniques and so on to get a wise choice for the industry applications. New concentration technologies and installations of the extract of TCM developed recently are reviewed in this paper. The characteristics of each method are analyzed and discussed in order to guide the industry applications. At the same time, the further research directions of concentration techniques of extract of TCM are also given.

OBJECTIVESTo observe the effects of pioglitazone on morphological changes and connective tissue growth factor (CTGF) expression of the transforming growth factor beta (TGF b)-induced rat hepatic stellate cells (HSCs) in vitro, and to investigate the anti-fibrotic mechanism of pioglitazone.

METHODSCultured rat HSCs were divided into a no-treatment control group, a TGF b-treated group, and a TGFb plus different dosage pioglitazone-treated group. The morphological changes of the cultured HSCs were observed. The expression of CTGF was assessed by immunohistochemistry and flow cytometry. The level of collagen type III in the culture supernatant was measured by ELISA.

RESULTSTGFb induced morphological changes, and increased the expressions of CTGF and collagen type III of the HSCs (P less than 0.05). Pioglitazone prevented the TGFb induced morphological changes of the HSCs. The expression of CTGF and the levels of collagen type III in the pioglitazone group were lower than the TGF b-treated group (P less than 0.05). This prevention effect was dose-dependent (P less than 0.05).

CONCLUSIONPioglitazone blocks the excretion of CTGF and collagen type III of cultured HSCs, preventing the development of liver fibrosis.
