Acta Mechanica Sinica 2012年第5期28卷 1271-1276页

作者： Chang yi wang Department of Mathematics Michigan State University

The starting flow due to a suddenly applied pressure gradient in a parallel plate channel which is rotating as a system is studied. Exact analytic series solutions to the unsteady Navier-Stokes equations are found by both the Laplace transform method and the separation of parameters method, the latter is shown to be superior. Rotation not only induces a secondary transverse flow but also alters the character of the transient flow rate and velocity profiles. Back flow and inertial oscillations occur, especially at higher rota- tion rates.

为探究岩脉侵入角度对隧道开挖的影响,文章以泸石高速石棉隧道开挖时地层遭遇不同角度岩脉侵入为工程背景,通过UDEC离散元计算,总结岩脉侵入角度对隧道开挖的影响,给出有效处理措施,并得出以下结论:岩脉和被侵入岩体界面易发生塑性滑移,隧道开挖后岩脉区围岩变形最大,且岩脉区围岩有开裂、滑移和隆起现象,围岩变形随角度的减小而减小。边墙与仰拱连接处轴力、剪力、弯矩均最大,安全系数最小,三种工况均在0.3左右。衬砌轴力、剪力的最大值随角度减小而增大,弯矩受角度的影响较小。岩脉区域的安全系数在向着岩脉倾斜方向更小。岩脉侵入区域隧道开挖应采用岩脉区域局部注浆、封闭仰拱、增大衬砌厚度三种方法来加固围岩和提高衬砌承载能力。

背景:激素性股骨头坏死与成骨细胞铁死亡密切相关,鹿角多肽可以通过抑制成骨细胞铁死亡,促进成骨细胞的存活与功能的建立,具有治疗激素性股骨头坏死的潜力,但其对成骨细胞铁死亡的调控机制尚未明确。目的:探究鹿角多肽抑制地塞米松诱导成骨细胞铁死亡的作用机制。方法:①采用不同浓度梯度的鹿角多肽与地塞米松干预MC3T3-E114细胞,CCK-8法检测细胞活性,确定鹿角多肽与地塞米松的作用浓度;②采用不同质量浓度梯度鹿角多肽干预被地塞米松(800μmol/L)处理后的MC3T3-E114细胞,分为空白对照组、地塞米松组、地塞米松+鹿角多肽组,采用CCK-8法计算不同质量浓度鹿角多肽对地塞米松(800μmol/L)干预MC3T3-E114细胞增殖的影响;③借助试剂盒检测空白对照组、地塞米松组、地塞米松+鹿角多肽组中超氧化物歧化酶活性及谷胱甘肽、丙二醛、脂质过氧化物、细胞铁、活性氧含量的变化,并应用Western blot检测谷胱甘肽过氧化物酶4、溶质载体家族7成员11蛋白的表达,验证鹿角多肽抑制铁死亡的通路。结果与结论:①CCK-8法检测细胞活性,结果确定后续实验选择以鹿角多肽(10 mg/mL)和地塞米松(800μmol/L)干预MC3T3-E114细胞处理24 h;②地塞米松干预后,丙二醛、脂质过氧化物、细胞铁、活性氧含量均升高(P<0.01),谷胱甘肽含量、超氧化物歧化酶活性均降低(P<0.01),谷胱甘肽过氧化物酶4、溶质载体家族7成员11蛋白表达降低(P<0.05-0.01);鹿角多肽干预后,上述各指标变化明显被逆转(P<0.05-0.01);③结果表明,鹿角多肽可能通过调控溶质载体家族7成员11/谷胱甘肽过氧化物酶4轴抑制成骨细胞铁死亡,发挥对激素性股骨头坏死的治疗作用。
