Results: in contrast with model group, SSM can (1) increase the survival rate of ARF in rats, cut down Scr and BUN at 24hr, improve renal function, slightly surpass Vp in its therapeutic effect;(2) mitigate the extent of renal pathologicchanges, decrease the numbers of renal tubule necroses and casts;(3) protect renal ultrastructure such as microvilli, mitochondria, endoplasmic reticulum of TEC, podocytic process of glomerulus epithelial cell,endothelial cell etc, better than Vp;(4) enhance SOD activity, lower MDA contents in renal cortex;(5) enhance NO contents in serum, reduce ET levels in plasma;(6) evidently cut down TNF- a contents in serum, superior to Vp;(7) antagonize calcium overload in TEC;(8) alleviate renal pathological changes in ARF metaphase (at 3d), advance regeneration and recovery of TEC, restore renal structure in ARF convalescence (at 5d), and better than Vp;(9) increase the expression of TEC PCNA and prepro EGFmRNA in ARF metaphase.

结果：与模型组相比，SSM能(1)提高ARF大鼠的存活率，降低24hr时Scr及BUN，改善肾功能，其疗效略优于维拉帕米；(2)减轻ARF肾脏病变程度，减少24hr肾小管坏死数及管腔内管型数；(3)对肾脏的超微结构如肾小管上皮细胞微绒毛、线粒体、内质网、肾小球上皮细胞足突、内皮细胞等形态结构均有一定的保护作用，其疗效略优于维拉帕米；(4)提高肾皮质SOD活性，降低MDA含量；(5)提高血清NO水平，同时降低血浆ET含量；(6)显著降低血清TNF-α的水平，疗效明显优于维拉帕米；(7)拮抗小管上皮细胞[Ca~(2+)]_i的升高；(8)使ARF中期(第3d时)肾组织病变较同期其它两组明显减轻，并使肾小管细胞再生修复提前，至ARF恢复期(第5d时)肾组织结构恢复重建良好；作用明显优于维拉帕米；(9)促进ARF中期肾小管上皮细胞PCNA的表达及EGF前体mRNA的合成，从而增加EGF的合成释放，而维拉帕米无此作用。

Project activities included a nationwide survey on the driver's safety belt use rate of the passenger car, the test-driving of COROLLA of TOYOYA, which have equipped with the SBR system and the questionnaire form the drivers in the test. Base on the data, we get the effectiveness of the SBR system to the people of different classification, such as age, income and education etc. The results indicated that the most effective and acceptable safety-belt reminder system concept was one that was adaptive, that is, one that changes its signal type and presentation modality depending on belt use behavior over some metric. Ultimately, base on the fatal data of passenger car driver in the traffic accident of our country and the relationship of the safety belt use rate between the dead driver and the rate in our research, we got the number of life that can be saved in the traffic accident when the SBR system was used, and then the economic losing related was calculated.

首先，通过实地拍摄得到了国内乘用车的安全带佩戴率数据；其次，通过对安装了安全带提醒装置的丰田花冠试验车的试驾调查，得到了安全带提醒装置对安全带使用的提高率，然后，利用Visual Basic对试驾问卷数据进行了处理，全面分析了安全带提醒装置对各类人群的不同效果；最后，以我国道路交通事故中轻、微型车辆驾驶员死亡人数为基础，参考交通事故中死亡驾驶员佩戴率与实际调查佩戴率之间的拟合关系以及使用安全带后驾驶员的存活率，得到了安全带提醒装置对减少国内交通事故中死亡人数的效果，然后基于所能挽救生命数量，对安全带提醒装置在降低国内交通事故中的经济损失方面的效果进行了分析。
