To investigate the modulation on the P-glycoprotein in the jejunum by combined use of Glycyrrhiza inflata and Kansui with ussing chamber and rt-pcr, Rhodamine 123 (R123), a P-gp substrate and fluorescein sodium (CF), a model drug of non-P-gp substrate transported by a passive diffusion were taken as investigational drugs. Because these two drugs can be easily assayed and widely used in various research fields. The permeability of R123 or CF via Wistar rat jejunum membranes was evaluated by in vitro ussing chamber after oral administration of four different decoctions of Glycyrrhiza inflata and Kansui for 1 week. And the concentration of R123 or CF was determined by the fluorospectrophotometry in the receiving solution. Meanwhile the expression of mdr1a in P-glycoprotein was detected by real-time fluorescent quantitative PCR. After oral administration of combined decoction of the single drug, the absorptive directed permeability of R123 increased significantly (P < 0.01). On the other hand, Kansui and combine decoction of the two drugs also decrease the permeability of secretory directed transport (P < 0.05). No action of Glycyrrhiza inflata was found on the secretory transport of R123 [Papp = (2.56 +/- 0.38) x 10(-5), cm x s(-1)] across the jejunum tissues, while Papp of control group was found [Papp = (2.35 +/- 0.27) x 10(-5), cm x s(-1)]. After oral administration of Kansui decoction for 1 week and 2 weeks, the levels of mdr1a expression in Wistar rats were lower than that of the control group, but there were no significant difference in the results. Meanwhile, Glycyrrhiza inflata had no effect on transport of CF across the jejunum tissues, though the other three groups could decrease the permeability of CF, as compared with control group. Kansui may slightly inhibit P-glycoprotein function in the intestinal membrane. For another, some compositions in Kansui inhibit P-glycoprotein function, and some others strengthen the tight junction between cells in the intestinal membrane to decrease permeability of CF. As the inhibitory action to P-glycoprotein was enhanced by combination of Glycyrrhiza inflata and Kansui, based on the results, it may be one of the mechanisms of creating toxicity once co-administration of Glycyrrhiza inflata and Kansui.

OBJECTIVETo study the correlation between syndrome differ classification of knee osteoarthritis and X-ray image, so as to provide evidence for clinical diagnosis and treatment.
METHODSFrom Jun. 2007 to Dec. 2007, 78 patients (108 knees) with knee osteoarthritis were reviewed, including 65 females (89 knees) and 13 males (19 knees), ranging in age from 41 to 77 years. According to the standards for the differentiation of syndrome in the treatment of knee osteoarthritis defined in Principle of Clinical Research for New Traditional Herbs, the patients were divided into three types: Type I, insufficiency of the liver and kidney, with stagnation of tendons and muscles, 43 knees; Type II, insufficiency of the spleen and kidney, with dampness infusion into bone and joints, 26 knees; Type I, deficiency of the liver and kidney, with inter-obstruction of phlegm and stasis 39 knees. Normotopia and lateral plain film of knee joint of weigh loading and in erect position, and patellofemoral Skyline plain flim was taken. Joint space narrow, osteophyte generation, subchondral osteosclerosis and subchondral cystic degeneration were evaluated. All data were analyzed by K independent samples nonparametric test in order to find out the correlation between syndrome differ classification of knee osteoarthritis and X-ray image.
RESULTSIt was shown that after K independent samples nonparametric test about syndrome differ classification of knee osteoarthritis and X-ray image: there were significant differences among three types about lateral patella osteophyte, condyles of tibia osteophyte and Type II was the most serious, Type I was secondary, Type II was the lightest. Other index had no obvious difference among the three groups.
CONCLUSIONThere is certain correlation between syndrome differ classification of knee osteoarthritis and X-ray image. There are significant differences among three types about lateral patella osteophyte, condyles of tibia osteophyte, the Type II is the most serious,Type I is secondary, Type II is the lightest. Consequently, it can be deduced that worse osteophyte is one of accordances of Type II-insufficiency of the spleen and kidney, with dampness infusion into bone and joints. And, the Type II is more serious stage in radiologic manifestation.

OBJECTIVETo investigate the modulation of Glycyrrhiza inflata and Daphne genkwa on the permeability characteristics of rhodamine 123 (R123), one P-glycoprotein (P-gp) substrate, across the jejunum membranes. And then approach the possible permeability mechanism of the drugs after co-administration of G. inflata and D. genkwa in gastrointestinal tract.
METHODThe permeability of R123 or fluorescein sodium (CF) via Wistar rat jejunum membranes was evaluated by in vitro diffusion chamber system after oral administration of four different decoctions and 0.9% sodium chloride (20 mL x kg(-1)) for 1 week. And the concentration of R123 or CF was determined by the fluorospectrophotometry. The apparent permeability coefficient (P(app)) was calculated by the equation P(app) = dQ/d(t) x (1/A x C0), where P(app) was expressed in cm/s, dQ/dT was the slope of the linear portion of the permeation curves, A was the diffusion area, and C0 was the initial concentration of rebamipide in the donor side, and then compare their differences were compared with control group.
RESULTAfter oral administration of G. inflata decoction, D. genkwa decoction and decoction of the combination of the previous decoctions, the absorptive directed transport of R123 was significantly increased (P < 0.05, compared with control group). On the other hand, D. genkwa could also decrease the permeability of secretory directed transport (P(app) = 2.98 +/- 0.59), while no action of G. inflata was found on the secretory transport of R123 ( P(app) = 5.24 +/- 3.98) across the jejunum tissues, while P(app) of control group was 4.38 +/- 1.18. Meanwhile, G. inflata had no effect on transport of CF across the jejunum tissues, though the other three groups could decrease the permeability of CF, as compared with control group.
CONCLUSIONG. inflata may slightly inhibit P-glycoprotein function in the intestinal membrane, while D. genkwa may be a relatively strong inhibitor of P-gp. For another, some compositions in D. genkwa inhibit P-gp function, and some others strengthen the tight junction between cells in the intestinal membrane to decrease permeability of CF. As the inhibitory action to P-gp was enhanced by combination of G. inflata and D. genkwa, based on the results, it may be one of the mechanisms of creating toxicity once co-administration of G. inflata and D. genkwa.

OBJECTIVETo establish the modal of perfusing and casting in hepatic duct system and explore the methods of three dimensional reconstruction with CT scanning image after filling hepatic duct.
METHODSAll canal of livers with integral porta hepatic were perfused with various filling material after pretreatment, then fixed and casted. Hepatic preparations that had been perfused were put into the model of modelling abdominal cavity and scanned with thin slice. The three dimensional duct structures of hepatic with three methods of MIP, SSD and computerized treatment.
RESULTSFourteen hepatic samples were filled and casted. Nine hepatic samples were scanned with slice height 1.0 mm, all 2514 slice images and average 279 images. Five hepatic samples were scanned with slice height 3.0 mm, all 512 slice images and average 102 images. Intrahepatic vein and portal vein system of three dimensional reconstruction were seen clearly with MIP method. The three dimensional established three dimensional images with SSD method was shown much stronger than that of MIP method. The three dimensional images of hepatic solid and hepatic vein system were established with method of comperized treatment. Vary three dimensional shape of hepatic solid and hepatic vein was obtained through different direction rotational.
CONCLUSIONSThe modal filled and casted hepatic duct system were practise. The images established three dimensional with methods of MIP, SSD and comperized treatment were seen clearly. The modal and images of thin slice CT scanning are a better method for researching hepatic duct system.
