International Journal of Traditional Chinese Medicine 2008;30(3):196,200-
The Book of Changes is known as a famous ancient book in China. In the chapter on Copula of this masterpiece the relations among the changes of heaven and earth, movement and stillness, and Qian and Qun have been revealed through adopting "YiXing" and "LiYi", two varieties of schools of Yi (Change). This paper sets out to compare the depiction of Yin and Yang, movement and stillness recorded in the book of the Yellow Emperor's Classic of Medicine with the notions mentioned above. It is also our attempt to discover the same intrinsic principle existed in both Chinese ancient philosophy and Chinese ancient medicine.

Objective To study the inhibition of berberine on organ anion transporters (OATs) and its bidirectional trans-membrane transport.Method The transgene cell lines of the organ anion transporters including OAT1,OAT2,OAT3,OAT4,OAT7,and URAT1 were constructed and selected by animal cell transgenic method mediated by transporter Lipo 3000.Wild type (WT) cells were used as control group,and activity of OATs was verified by adding their radiolabeled substrates and inhibitors.The inhibition of 100 μmol/L berberine on the transporters was investigated in vitro.The IC50 of berberine on URAT1 was also determined.The bidirectional transport of berberine was studied through the Caco-2 model.Result The results showed that 100 μmol/L berberine inhibited the activity of OAT1,OAT2,OAT3,OAT4,OAT7 and URAT1 to (70.48±4.23)%,(69.13±1.28)%,(72.12±3.28)%,(79.77±6.49)%,(69.51 ±5.99)% and (38.4 ± 2.67)% respectively,the IC50 of berberine to URAT 1 was 13.19 μmol/L,the Papp (A-B) of 50 μmol/L and 100 μmol/L berberine were separately 0.28 × 10-6 and 0.40 × 10-6 cm/s,and the effiux rates were separately 3.18 and 3.15.Conclusion Berberine shows a stronger inhibition to URAT1 compared to OAT1,OAT2,OAT3,OAT4 and OAT7.Berberine may be the substrate of some effiux transporters.This study provides theoretical basis for explaining the low bioavailability ofberberine and forecasting the possible drug-drug interaction.

Wutou-Gancao herb-pair is extensively used to attenuate the toxicity and enhance the efficacy of aconite. In this study, potential synergic mechanism of the herb pair was investigated by utilizing multiple ap-proaches. In silico and in vitro Caco-2 cell models were applied to study the potential binding mode of bioactive ingredients existing in liquorice with P-glycoprotein (P-gp), as well as the inhibition effects on P-gp. Additionally, anti-inflammatory activity of aconitine (AC) combined with active ingredients of liquorice, as well as pharmacokinetic patterns of AC after co-administration was investigated. Anti-inflammatory effect of AC (1 mg/kg) in rats was enhanced in combination with bioactive ingredients of liquorice (10 mg/kg). In the meanwhile, the exposure of AC in vivo was altered, in terms of Cmax and AUC. For instance, the Cmax and AUC were increased to 1.9 and 1.3 folds, respectively, when used in combination with liquiritigenin. The in silico study revealed the potential binding mode with outward facing conformation of P-gp. The resulting data obtained from transport of rhodamine-123 (Rh-123) across Caco-2 cell monolayer further indicated that the function of P-gp was inhibited by chemicals in liquorice. The synergic effect was therefore proposed to be attributed to inhibition of P-gp by liquorice since AC has been demonstrated to be the substrate of P-gp. The resuls revealed that potential synergic mechanism of Wutou-Gancao herb-pair by inhibiting function of key efflux transporter P-gp to enhance the exposure of AC in systematic circulation, and further the anti-inflammatory effect, which helps clarify the compatibility rationale of these two herbs.

This study aimed to investigate the improvement of tolance and pharmacodynamics of nano-micelle irinotecan formulation compared with irinotecan hydrochloride injection(Campto). The toxic effects of the two formulations on colorectal cancer cells COLO205, HT-29, HCT-8 and SW480 were tested in vitro. COLO205 tumor-bearing mouse model was constructed. The two preparations were given via tail vein injection to investigate the maximum tolerance dose(MTD)of tumor-bearing mice to the two preparations, and then to explore the improvement of anti-tumor efficacy of nano-micelle irinotecan formulation near the MTD. The results showed that there was no significant difference in the inhibitory effect of the two formulations on the four colorectal cancer cells in vitro. The MTD of nano-micelle irinotecan formulation and Campto was 432. 0 and 276. 5 mg/m2 respectively. Both of the two formulations showed significant anti-tumor effect in vivo, and the relative tumor proliferation rate and tumor wet weight inhibition rate of nano-micelle irinotecan formulation at high dose(345. 6 mg/m2)were significantly better than those of Campto at two doses(177. 0 and 221. 2 mg/m2)(P< 0. 05).
