This may be explained by follows: First, Decoction Shenkangling can regulate the homeostasis of NEI network and reduce the increased activity of NF-κB to restrain the action of inflammatory-sclerotic media; Second, it can redress the disequilibrium of the ratio of TXA2/PGI2 to reform the hypercoagulable state; Third, it can enhance albumin and reduce cholesterol and triglyceride; Fourth, it can amend the renal damage and protect the function of renal tubule and stroma to prevent the transformation from MCD to FSGS; Last, it can lessen urine protein in AN rats markedly and relieve the side effects of prednisone.4. NF-κB, TXA2 and PGI2, along with the renal pathomorphology and so on can all be the indexes of the diagnosis of Symptom of "Kidney Deficiency and Blood Stasis" and the application of Methods of "Benefiting the kidney and Promoting blood circulation" in TCM.5. The curative effects on AN rats by treatment of integrating Traditional Chinese Medicine with prednisone are much better than using prednisone only. And the curative effects on AN rats by treatment of matching Decoction Shenkangling, having the function of "Benefiting the kidney and Promoting blood circulation", with Prednisone are much better than using Prednisone only.6. When it referred to decreasing urine protein, cholesterol and triglyceride and increasing albumin, Decoction Zhibodihuang excesses Decoction Taohongsiwu. However, when it referred to regulating the disequilibrium of TXA2/PGI2 and meliorating renal lesion, Decoction Taohongsiwu exceeds Decoction Zhibodihuang.7. The curative effects on AN rats by treatment of matching Methods of "Benefiting the kidney and Promoting blood circulation" with Prednisone overmatches using Prednisone matching Method of "Benefiting the kidney" or Method of " Promoting blood circulation" only.

益肾活血中药肾康灵能显著改善AN鼠的肾虚血瘀证的临床表现和实验指标，这可能与中药肾康灵能调理AN鼠机体的NEI网络功能稳态，降低异常升高的NF-κB活性，抑制免疫炎症/硬化介质环节，纠正失衡的TXA2/PGI2，改善AN鼠血液高凝状态，提高AN鼠的血清Alb，降低Ch和TG，减轻AN鼠的肾脏组织病理学变化，保护肾小管－间质功能，阻止MCD向FSGS转化；显著减轻AN鼠的尿蛋白水平以及减轻激素副作用有关。4、NF-κB、 TXB2和6-keto-PGF1α以及肾脏病理形态学改变等，都可作为中医肾虚血瘀证诊断和益肾活血法应用的客观指标。5、中西医结合干预AN鼠疗效优于单纯激素治疗；强的松配合益肾活血中药肾康灵组的综合疗效显著优于单纯强的松组。6、知柏地黄汤组在降低尿蛋白、提高血清Alb、降低Ch和TG疗效上优于桃红四物汤组；桃红四物汤组在纠正失衡的TXA2/PGI2和减轻肾脏病理损害方面优于知柏地黄汤组。7、激素配合益肾活血法干预AN鼠在一定程度上优于激素配合益肾法或活血法。
