ObjectiveTo observe the modified Xiaoqinglong decoction and its ingredient-reduced prescription on plasma levels of IL-5 and TNF-ct in rats,and to explore its mechanism of treating AR.To make clear the law of combination in modified Xiaoqinglong decoction.MethodsThe modified Xiaoqinglong decoction was divided into six groups,namely,reinforcing qi group,warming yang group,expelling retained morbid fluid group,reinforcing qi and warming yang group,reinforcing qi and expelling retained morbid fluid group,warming yang to expel retained morbid fluid group.90 rats were randomly divided into nine groups,namely,normal control group,model group,reinforcing qi group,warming yang group,expelling retained morbid fluid group,reinforcing qi and warming yang group,reinforcing qi and expelling retained morbid fluid group,warming yang to expel retained morbid fluid group,and the whole decoction group,with 10 rats in each group.Rat model of allergic rhinitis was made by the use of adjuvant systemic antigen sensitization and local attack,the normal control group and model group were fed with normal saline,the other groups were treated with appropriate drugs,once a day oral administration,continuous for 4 weeks.Detected plasma IL-5 and TNF-α levels of each group in rats.ResultsThe contents of plasma IL-5 (16.0±2.7)mg/L and TNF-α (57.5±8.0)mg/L in the model group was significantly increased,while it was significantly reduced in the reinforcing qi group,warming yang group,expelling retained morbid fluid group,refinorcing qi and warming yang group,reinforcing qi and expelling retained morbid fluid group,warming yang to expel retained morbid fluid group with plasma IL-5[each group was (12.9± 3.1) mg/L、(11.8 ±2.8) mg/L、(12.0±2.3) mg/L、(12.3±2.3) mg/L、(11.1±2.1)mg/L、(11.2±2.5)mg/L、(8.42.3)mg/L respectively]and TNF-α[each group was (27.7±5.7)mg/L、(29.5 ± 3.7) mg/L、(31.2 ± 4.9) mg/L、(28.1 ± 2.8) mg/L、(33.4 ± 5.6) mg/L、(26.3 ± 3.9) mg/L、(21.6 ±4.9) mg/L respectively],the whole decoction group effect was significant compared with the other treated groups (P＜0.05).ConclusionThe modified Xiaoqinglong decoction and its ingredient-reduced prescription can regulate plasma levels of IL-5 and TNF-α.The modified Xiaoqinglong decoction had best results in reinforcing qi,warming yang and expelling retained morbid fluid.

Objective To observe the effects of Purpura decoction and its disassembled prescriptions on peripheral blood reticulated platelets (RP) and serum thrombopoietin (TPO) of idiopathic thrombocytopenic purpura (ITP) model mice, to explore the action mechanism and core structure of the prescription. Methods Totally 84 BalB/c mice were randomly divided into normal group, model group, prednisone group, Purpura decoction group, Buyi Qixue group, Buqi Huoxue group and Buxue Huoxue group. ITP mouse model was made by injecting intraperitoneally guinea pig-antimouse platelet serum. From the 5th day of modeling, mice were intragastrically administered. The normal group and model group were fed with normal saline 0.2 mL per mouse. Purpura decoction group was fed with Purpura decoction 0.43 mL per mouse. Buyi Qixue group was fed with Buyi Qixue decoction 0.36 mL per mouse. Buqi Huoxue group was fed with Buqi Huoxue decoction 0.27 mL per mouse. Buxue Huoxue group was fed with Buxue Huoxue decoction 0.3 mL per mouse. Prednisone group was fed with prednisone acetate suspension 0.2 mL per mouse. Ten days later, took the blood from the eyeball and isolated serum, the mouse peripheral platelet, RP and TPO were observed. Results After treatment, the platelet count of treatment groups was improved. Compared with before treatment, Purpura decoction group,Buqi Huoxue group and prednisone group had significant difference in platelet count (P<0.05). The RP of model group was significantly higher than the normal group (P<0.05), but RP absolute value was lower than the normal group (P<0.05). Compared with the model group, RP of treatment groups reduced (P<0.05), and RP was negatively correlated with platelet count (P<0.05). TPO level of the model group was higher than that of the normal group (P<0.01). TPO of treatment groups declined significantly, and had significant differences with that of the model group (P<0.05). Conclusion Core structure of Purpura decoction is qi tonifying and blood activating drug. The mechanism of treating ITP is related with lowering RP and TPO.
