To investigate the influence of the difference enhancers on the transport mechanism of chlorogenic acid (CGA) across Caco-2 cells model, a RP-HPLC method was adopted to detect the concentrations of CGA. At the concentrations of 20 to 80 microg x mL(-1), the difference of absorption rate constants (K(a)) was not statistically significant. At the concentrations of 40 and 20 microg x mL(-1), the ratios of apparent permeability coefficients (P(app)) of the apical to basolateral and the basolateral to apical were 1.14 and 1.18, respectively. With the effect of enhancers K(a) and P(app) increased, the absorption half-life (T1/2) decreased. CGA passed through the Caco-2 cell membrane mainly by passive transport. It showed that monocarboxylic acid transporter (MCT) could be involved in the across membrane transport process of CGA. Borneol had no effect on the cell membrane transport processes. The order of increasing absorption of CGA caused by the enhancers was sodium lauryl sulphate > sodium taurocholate > carbomer.

This article was aimed to study the action of antigout effects of compoundWeifu. Through the acute gouty arthritis models of rabbits and rats induced by micro-crystal sodium urate (MSU). The histopathological changes of synovial tissues among rabbits were observed. And the contents of TNF-α, IL-1β, IL-6 in rabbit serum were determined. The swelling degree of the rats’ feet and the content of prostaglandin E2 (PGE2) from the inflammatory exudate foot induced by MSU were also determined. The antigout effects of compoundWeifu were observed. The results showed that the grade of the vascular congestion, swelling and inflammatory cell infiltration in synovial tissues in the high-dose and medium-dose CompoundWeifu group had significantly improved (P <0.05). And the levels of TNF-α, IL-1β, IL-6 in serum were significantly decreased (P< 0.05, orP < 0.01). It can obviously reduce the swelling degree induced by MSU, and the level of PGE2 in the inflammatory exudate foot (P< 0.05, orP < 0.01). It was concluded that CompoundWeifu had obvious antigout effects in the study.

OBJECTIVE:To study the influential factors related to efficacy of Peach kernel-Rheum palmatum couplet medi-cines in TCM formula,and to reveal the general regularity of compatibility environment,common ratio,processing variety and dosage forms of P. kernel-R. palmatum couplet medicines. METHODS:Using Chinese Medical Prescription Selected Dictionary ed-ited by Peng Huairen as data source,142 formulas of P. kernel-R. palmatum couplet medicines were collected. By establishing data-base,compatibility types of P. kernel-R. palmatum couplet medicines,as well as common ratio,processed prodact,dosage form were classified statistically. The influential factors related to efficacy of P. kernel-R. palmatum couplet medicines with different pro-portions were summarized. RESULTS:The efficacy of P. kernel-R. palmatum couplet medicines could be divided into 6 aspects and 11 roles,including activating blood circulation to dissipate blood stasis(activating blood to relieve pain,promoting blood circula-tion to eliminate disease,activating blood to promote menstruation,breaking stagnant and eliminating blood stasis),eliminating carbuncle and detoxicating(cleaning intestine and clearing away the pathogenic heat of lung,eliminating carbuncle and expelling pus,eliminating sore and detoxicating),expelling the pathogenic heat to loosen the bowels,warming yang for dispelling cold,forti-fying the spleen and nourishing the stomach,relaxing tendon and activating blood. The compatibility environment of P. kernel-R. pal-matum couplet medicines were mainly compatible with TCM for activating qi to eliminate stasis,activating blood to promote menstru-ation,breaking stagnant and eliminating blood stasis,expelling the pathogenic heat to expel stasis. The ratio of P. kernel to R. palma-tum ranged 1 : 8-4 : 1,and the ratio ranged 1 : 8-3 : 1 when performing the role of actirating blood circalation to dissipate blood stasis. Common processed products were crude P. kernel and prepared R. palmatum. Common dosage forms were mainly decoction,pill and powder. CONCLUSIONS:Compatibility environment,ratio,processing varieties,dosage forms influence the effects of P. kernel-R. palmatum couplet medicines,especially compatibility environment.
