Differential role of YiGanKang decoction in IL-1β induction of IL-1RI and AP-1 in rat hepatic stellate cell

Background/Aim

YiGanKang, a combination of Chinese herbs, has anti-fibrosis effects in chronic liver diseases. The present study tries to demonstrate differential role of YiGanKang Decoction in interleukin-1β (IL-1β) induction of the type I receptor (IL-1RI) and the activator protein 1 (AP-1) in rat hepatic stellate cell (HSC).

Methods

Flow cytometry was used to detect the IL-1RI expression. Electrophoretic mobility shift assays was used to detect AP-1 activity.

Results

IL-1RI expression after IL-1β treatment for 0, 2, 10, 60, and 120 min was 227.08 (13.15), 268.43 (8.93), 442.97 (7.00), 367.66 (14.70), and 261.58 (15.08), respectively. The differences between IL-1RI expression after treatment for 10 and 60 min were significantly higher than the corresponding values in the control (P < 0.01, P < 0.01, respectively); After pretreatment with YiGanKang Decoction, IL-1RI expression induced by IL-1β was not decrease obviously; IL-1β could activate AP-1 in rat HSCs (P < 0.01). Meanwhile YiGanKang Decoction could inhibit activity of AP-1 induced by IL-1β (P < 0.01), and the inhibition rate was 42.71%.

Conclusion

YiGanKang Decoction could not decrease IL-1RI expression, but it could inhibit activity of AP-1 in rat HSCs induced by IL-1β.     

Herb–drug pharmacokinetic interaction between radix astragali and pioglitazone in rats

Ethnopharmacological relevance

Radix astragali (RA) was the most frequently used traditional Chinese medicine (TCM) according to the statistics on 52 anti-diabetic formulas recorded in New National Traditional Chinese Medicine; it was employed in 34 out of the 52 formulas. The aim of this study was to elucidate potential pharmacokinetic interaction between RA and pioglitazone, and to provide guidance for clinical medicine safety.

Materials and methods

A specific and rapid UPLC–MS/MS method was established to quantify pioglitazone in rat plasma. Then healthy and type 2 diabetes mellitus (T2DM) rats were each divided into control and RA decoction (RAD) administration groups—healthy, healthy-RAD, T2DM, T2DM–RAD; pharmacokinetics of pioglitazone was carried out after RAD was administrated to rats for 7 days.

Results

The established UPLC–MS/MS method was rapid, specific, and precise. Between healthy and healthy-RAD groups, half-life (T_1/2), area under the curve (AUC _0–t), Vz/F, and Cl/F showed mild yet statistically significant differences; no significant difference for any above parameter was detected between T2DM and T2DM–RAD groups.

Conclusion

RAD co-administration did not affect the pharmacokinetics of pioglitazone especially in diabetic groups; RA and pioglitazone might be feasible herb–drug co-effectiveness.
