Results: Tubulointerstitial damage index, tubulointerstitial fibro- sis index, and expression of TGF-β1 in group U were significantly higher than those in group S (P.01). These indexes were obviously lower in group A than those in group U (P.05). TDI and TFI positively correlated with expression of TGF-β1 respectively.

对U形渠道量水槽进行了选型，在选型的基础上，提出以U形渠道直壁式量水槽作为本研究的优选体型，并对U形渠道直壁式量水槽的体型、喉道长度、喉道宽度、过渡段长度、水尺位置、设计方法进行了优化研究，所得结果已在工程实践中应用，取得了良好的经济效益和社会效益。

Firstly, saltating sand grains in various height layers mostly rotate clockwise; the rate of counterclockwise rotation changes from 16.7 to 33.3% for three different friction wind speed (u*= 0.67, 0.83, and 0.87 m/s). However, their mean rotational speeds were not significantly different, irrespective of whether the grains rotated clockwise or counterclockwise. The mean counterclockwise rotational speeds of sand grains for friction wind speed u*= 0.67, 0.83, and 0.87 m/s were 427, 519, and 604 rev/s, versus 429, 522, and 609 rev/s, respectively, in the clockwise direction.
