紫癜汤及其拆方对特发性血小板减少性紫癜模型小鼠网织血小板和血小板生成素的影响

摘要

目的：观察紫癜汤及其拆方对特发性血小板减少性紫癜(ITP)模型小鼠外周血网织血小板(RP)、血清中血小板生成素(TPO)的影响,探讨该方提升ITP模型小鼠血小板的作用机制及其核心结构。方法将84只BalB/c 小鼠随机分为正常组、模型组、泼尼松组、紫癜汤组、补益气血组、补气活血组、补血活血组。除正常组外,其余各组采用免疫法腹腔注射豚鼠抗小鼠血小板血清建立ITP小鼠模型。于造模第5日起灌胃给药,正常组、模型组给予生理盐水0.2 mL/只,紫癜汤组给予紫癜汤0.43 mL/只,补益气血组给予补益气血汤0.36 mL/只,补气活血组给予补气活血汤0.27 mL/只,补血活血组给予补血活血汤0.3 mL/只,泼尼松组给予醋酸泼尼松混悬液0.2 mL/只,连续10 d。眼球取血分离血清,检测小鼠外周血小板、RP及TPO。结果各给药组均能提高ITP小鼠血小板计数,与给药前比较,紫癜汤组、补气活血组、泼尼松组差异有统计学意义(P＜0.05)；模型组 RP显著高于正常组,RP绝对值低于正常组(P＜0.05)。各给药组 RP降低,与模型组比较差异有统计学意义(P＜0.05),且RP与血小板计数呈负相关(P＜0.05)。模型组血清中TPO水平高于正常组(P＜0.05)；各给药组TPO水平下降,与模型组比较差异有统计学意义(P＜0.05)。结论紫癜汤的核心结构是补气药、活血药,其能有效提升ITP模型小鼠血小板的机制与降低外周血RP及血清中TPO有关。%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.
