Objective To determine the optimal model for the evaluation of pharmacodynamics of Fangji Huangqi Decoction. MethodsBy changing the doses and times of doxorubicin and the intervention of Fangji Huangqi Decoction and a series of test drugs, the effects of different doses and times of doxorubicin on the model were explored, and body weight, organism index, urine protein quantitation, renal histopathology results, and serum biochemistry can be regarded as evaluation indexes. Results For M1(5 + 2) mg/kg model, the mortality rate of rats was higher. For M2(6 mg/kg) model, the mortality rate was up to 20%, and the indicators reflecting renal function did not callback, but instead it showed much higher levels than the model group after receiving the test drug. For M3(4 + 2) mg/kg model, the callback of part of the indexes, such as lung and kidney organ index, serum total triglyceride, and total protein levels, occurred after receiving the test drug, but the curative effect is not ideal. For M4 or M4'(4 + 1) mg/kg model, the quantitative level of urinary protein in model rats was significantly different from that in the control at the 14 th d, and the sustained and stable growth trend was observed; Moreover, the indicators mentioned above have different degrees of callback with high-, middle-, and low dose of Fangji Huangqi Decoction. Conclusion The final model weight of the rats was determined to be about 300 g, and the cumulative dose of doxorubicin was 5 mg/kg tail intravenous injection of doxorubicin was adopted as follows: on the 1 st d of the experiment, 4 mg/kg doxorubicin was injected, and followed another 1 mg/kg at intervals of 1 week, which was the best way to evaluate the pharmacological effect of the related drugs derived from the Fangji Huangqi Decoction and the middle dose was the best.
