本文旨在研究高原低氧暴露后小鼠海马组织铁死亡的发生情况及相关通路的变化。采用海拔4010 m的高原环境建立低压性缺氧模型,用HE染色观察小鼠海马组织形态学变化,用免疫组织化学染色法观察海马组织脂质过氧化水平,用试剂盒测定海马组织丙二醛(malondialdehyde,MDA)、还原型谷胱甘肽(glutathione,GSH)和Fe^(2+)水平,用Western blot检测海马组织中谷胱甘肽过氧化物酶4(glutathione peroxidase 4,GPX4)、溶质载体家族7成员11(solute carrier family 7 member 11,SLC7A11)、铁蛋白重链1(ferritin heavy chain 1,FTH1)、转铁蛋白1(ferroportin 1,FPN1)、转铁蛋白受体1(transferrin receptor 1,TfR1)、铁死亡抑制蛋白1(ferroptosis suppressor protein 1,FSP1)和长链脂酰辅酶A合成酶4(acyl-CoA synthetase long chain family member 4,ACSL4)蛋白表达水平。结果显示,与平原对照组比较,高原低氧暴露1、3、7和14 d组小鼠海马齿状回均出现明显的病理损伤,排列紊乱,核固缩明显。与平原对照组比较,高原低氧暴露增加小鼠海马齿状回4-羟基壬烯醛(4-hydroxynonenal,4-HNE)和海马MDA含量,显著降低海马GSH含量;高原低氧暴露14 d组小鼠海马Fe^(2+)含量显著增加。与平原对照组比较,高原低氧暴露小鼠海马GPX4、FTH1、FPN1、TfR1和FSP1蛋白表达水平均显著下调,SLC7A11蛋白表达水平仅在高原低氧暴露7 d组显著下调,ACSL4蛋白表达水平仅在高原低氧暴露14 d组显著上调。以上结果提示,高原低氧暴露14 d可减少小鼠海马GSH合成,下调GPX4表达,导致GSH代谢紊乱,抑制铁储存和铁外排,促进脂质过氧化反应发生,同时抑制还原型辅酶Q10(CoQ10H2)抗脂质过氧化作用,这可能导致小鼠海马组织中细胞铁死亡发生。

The pier, placed at the outlet of the pressure flow section, is an effective design to deal with the problems of the manufacture and operation of the gates fbr a discharge tunnel with high water head. It is crucial to control the water-wing, induced by this type of the pier. Through observing the phenomena of the water-wing, the reason of the water-wing inception, i.e., the concave of the flow surface, was presented, and a type of the new pier with bottom underlay was designed. The hydraulic characteristics of the pier, including the variations of the water-wing features, both length and height, with the water head, as well as with the concave depth, and with the height of the bottom underlay, and the variations of the concave depth with the height of the bottom underlay, were investigated by physical model experiments. The results show that the approach of the modification of the concave through the structures with the bottom underlay-type pier is remarkably effective in the water-wing control.

Objective Waist circumference, waist-to-hip ratio and waist-to-height ratio, which are the indicators or measures of abdominal adiposity, have long been hypothesized to increase the risk of stroke; yet evidence accumulated till date is not conclusive. Here, we conducted a dose-response meta-analysis to summarize evidences of the association between these measures of abdominal adiposity and the risk of stroke. Methods PubMed and Web of Science databases were searched from inception to May 2015. Two investigators independently conducted the study selection and data extraction. Dose-response relationships were assessed by the generalized least squares trend estimation, while the summary effect estimates were evaluated by the use of fixed- or random-effect models. Subgroup and sensitivity analyses were performed to assess the potential sources of heterogeneity and the robustness of the pooled estimation. Publication bias of the literature was evaluated using Begg＇s and Egger＇s test. Results Altogether 15 prospective cohort studies were identified in this study. The summary of relative risks （95% confidence intervals） of stroke for the highest versus the lowest categories was 1.28 （1.18-1.40） for waist circumference, 1.32 （1.21-1.44） for waist-to-hip ratio, and 1.49 （1.24-1.78） for waist-to-height ratio. For a 10-cm increase in waist circumference, the relative risk of stroke increased by 10%; for a 0.1-unit increase in waist-to-hip ratio, the relative risk increased by 16%; and for a 0.05-unit increase in waist-to-height ratio, the relative risk increased by 13%. There was evidence of a nonlinear association between waist-to-hip ratio and stroke risk, Pnonlinearity=0.028, Conclusion Findings from our meta-analysis indicated that waist circumference, waist-to-hip ratio, and waist-to-height ratio were positively associated with the risk of stroke, particularly ischemic stroke.
