摘 要:目的探讨痹祺胶囊全方益气养血、活血通络、抗炎及镇痛作用。方法分别采用大鼠气血两虚模型和微循环障碍模型观察痹祺胶囊的益气养血和活血化瘀作用;采用小鼠急性耳肿模型观察痹祺胶囊的抗炎作用;采用小鼠热板法和扭体模型观察痹祺胶囊的镇痛作用。各功能研究用动物分别分为空白组(扭体实验除外)、模型组(热板实验除外)、阳性药组、痹祺胶囊低剂量组(相当于临床用量)、中剂量组(相当于临床2倍用量)、高剂量组(相当于临床4倍用量)。末次给药1 h后取材,检测全血中外周血细胞数量,采用ELISA法检测血清中促红细胞生成素(erythropoietin,EPO)含量,采用流式细胞术检测脾脏中CD4^(+)/CD8^(+)比例,用于初步评价痹祺胶囊的益气养血作用;采集大鼠肠系膜毛细血管流速,对全血进行黏度分析,采用凝血酶时间(thrombin time,TT)试剂盒对血清进行凝血时间分析,用于初步评价痹祺胶囊的活血化瘀作用。结果痹祺胶囊低剂量组(相当于临床剂量)具有显著的益气养血及抗炎镇痛作用(P<0.05、0.01),活血化瘀作用不明显;痹祺胶囊中剂量(相当于2倍临床剂量)表现出显著的抗炎及镇痛作用(P<0.05、0.01),益气养血作用较弱,活血化瘀作用不明显;痹祺胶囊高剂量组具有显著的益气养血、活血化瘀、抗炎及外周镇痛作用,中枢镇痛作用不明显,具体表现在可提高外周血细胞数量、外周血中EPO含量及改善脾脏T淋巴细胞CD4^(+)、CD8^(+)分型(P<0.05、0.01),改善毛细血管流速、降低不同切速下全血黏度,并延长TT(P<0.05、0.01),抑制巴豆油引起的耳肿及醋酸诱发的疼痛反应(P<0.05、0.01)。结论痹祺胶囊具有明显的益气养血、活血化瘀及抗炎镇痛作用,并为明确其功能药味奠定药效基础。Objective To explore the pharmacodynamic effect of Biqi Capsule(痹祺胶囊)on benifiting qi and nourishing blood,promoting blood circulation to dissipate blood stasis,and anti-inflammation and analgesia.Methods The effects of benifiting qi and nourishing blood,promoting blood circulation and removing blood stasis of Biqi Capsule were respectively observed in rat models of qi and blood deficiency and microcirculation disturbance.The anti-inflammatory effect of Biqi Capsule was observed by acute otoedema model in mice.The analgesic effect of Biqi Capsule was observed by hot plate/writhing model in mice.The animals were respectively divided into blank group(except for writhing experiment),model group(except for hot plate experiment),positive drug group,Biqi Capsule low-dose group(equivalent to clinical dosage),Biqi Capsule medium-dose group(equivalent to two times of clinical dosage),Biqi Capsule high-dose group(equivalent to four times of clinical dosage).Samples were collected 1 h after the last administration of Biqi Capsule,the number of peripheral blood cells in the whole blood was detected,the content of erythropoietin(EPO)in serum was detected by ELISA,and spleen CD4^(+)/CD8^(+)ratio was detected by flow cytometry,which were used to preliminatively evaluate the effect of benifiting qi and nourishing blood of Biqi Capsule.The flow velocity of mesenteric capillaries of rats was detected,the viscosity of whole blood was analyzed,thrombin time(TT)kit was used to analyze the coagulation time of serum,so as to preliminically evaluate the effect of Biqi Capsule on promoting blood circulation and removing blood stasis.Results Biqi Capsule low-dose group(equivalent to clinical dose)had significant effects of benifiting qi and nourishing blood,antiinflammatory and analgesic effects(P<0.05,0.01),the effects of promoting blood circulation and removing blood stasis was not obvious.Biqi Capsule medium-dose group(equivalent to two times of clinical dose)showed significant anti-inflammatory and analgesic effects(P<0.05,0.0
