| 目的 探讨低温条件下兔肾实质弹性的变化。方法：将20只新西兰兔平均分为5组：第1组为对照组,第2组-5℃~-14℃低温处理4h,第3组-5℃~-14℃低温处理8h,第4组-15℃~-24℃低温处理4h,第5组-15℃~-24℃低温处理8h。每组实验兔处理后进行二维超声和声辐射力脉冲成像(Acoustic Radiation Force Impulse, ARFI)技术检查,观察肾实质的回声,测量肾实质的剪切波速度(Shear Wave Velocity ,SWV)。结果：各组实验兔肾实质的回声无明显改变,与对照组相比,其余各实验组的SWV值均增大(P＜0.05)；与第2组相比,第4、5组的SWV值增大(P＜0.05)；与第3组相比,第4、5组的SWV值增大(P＜0.05)；与第4组相比,第5组的SWV值增大(P＜0.05)。结论：声脉冲辐射力技术可以反映低温条件下兔肾实质弹性的改变,可以为临床研究低温导致肾脏损伤的早期诊断提供有意义的信息。 |

| Abstract: |
| Objective To study the change of elasticity in rabbits’ kidney in low temperature conditions. Methods 20 New Zealand rabbits were randomly divided into five groups，4 rabbits in each group .The first group was considered as control group which was under room temperature conditions .The second group was treated under-5℃~-14℃for 4hours.The third group was treated under-5℃~-14℃for 4hours.The fourth group was treated under-15℃~-24℃for 8hours.The fifth group was treated under-15℃~-24℃for 8hours．The echo of kidney were evaluated by two-dimensional ultrasound and shear wave velocity(SWV) were quantitatively analyzed by Acoustic Radiation Force Impulse (ARFI) technique after treatment .
Results No significant changes were found in the echo of kidney in any group. Compared with the control group，the SWV of the other groups were significantly increased (P＜0.05). Compared with the second group，the SWV of the fourth and fifth group were significantly increased (P＜0.05). Compared with the third group，the SWV of the fourth and fifth group were significantly increased (P＜0.05). Compared with the fourth group，the SWV of the fifth group were significantly increased (P＜0.05).Conclusions Acoustic Radiation Force Impulse technique can reflect the change of elasticity in rabbits’ kidney in low temperature conditions and provide useful information for the early diagnosis of renal damage caused by low temperature for clinical research． |
