| 方法 | Cellular impedance assay
VEC proliferation was assessed using a cellular impedance assay. VECs were seeded into 8-well E-plates (ACEA Biosciences, Inc., San Diego, CA, USA) at a density of 7,500 cells/well and cultured overnight. Cells were cultured with complete medium, supplemented with 0.1% dimethyl sulfoxide (DMSO) as a control, the PPARγ agonist rosiglitazone (10 μM) or the PPARγ antagonist T0070907 (15 μM) respectively, as previously described. Cellular proliferation was dynamically monitored using the iCELLigence(TM) real-time cell analysis (RTCA) system (ACEA Biosciences, Inc.) at 37°C in a 5% CO2 atmosphere for 100 h. The cell index, which reflects the adhesion, proliferation and viability of the cells through electrical impedance across interdigitated microelectrodes integrated on the bottom of the E-plates, was automatically calculated for each E-plate well using RTCA software version 1.2 (Roche Diagnostics, Basel, Switzerland) and graphs were generated in real-time using the iCELLigence(TM) system (30,31). Each treatment was performed in duplicate and three independent experiments were conducted. |

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
