Purpose:Intramedullary nailing is the preferred internal fixation technique for the treatment of subtrochanteric fractures because of its biomechanical advantages. However, no definitive conclusion has been reached regarding whether combined cable cerclage is required during intramedullary nailing treatment. This study is performed to compare the clinical effects of intramedullary nailing with cerclage and non-cerclage wiring in the treatment of irreducible spiral subtrochanteric ***:Patients with subtrochanteric fractures admitted to our center from January 2013 to December 2021 were retrospectively analyzed. The patients were enrolled in the case-control study according to the inclusion and exclusion criteria and divided into the non-cerclage group and the cerclage group. The patients'' clinical data, including the operative time, intraoperative blood loss, hospital stay, reoperation rate, fracture union time, and Harris hip score, were compared between these 2 groups. Categorical variables were compared using Chi-square or Fisher''s exact test. Continuous variables with normal distribution were presented as mean ± standard deviation and analyzed with Student''st-test. Nonnormally distributed variables were expressed as median (Q1, Q3) and assessed using the Mann-Whitney test. Ap < 0.05 was considered ***:In total, 69 patients were included in the study (35 patients in the non-cerclage group and 34 patients in the cerclage group). The baseline data of the 2 groups were comparable. There were no significant difference in the length of hospital stay (z = -0.391,p = 0.696), operative time (z = -1.289,p = 0.197), or intraoperative blood loss (z = -1.321,p = 0.186). However, compared with non-cerclage group, the fracture union time was shorter (z = -5.587,p < 0.001), the rate of nonunion was lower (χ2= 6.030,p = 0.03), the anatomical reduction rate was higher (χ2= 5.449,p = 0.03), and the Harris hip score was higher (z =-2.99,p = 0.003) in

泛素化修饰是植物蛋白质翻译后修饰的重要组成部分,通过对蛋白质的选择性降解,参与调控植物生长发育和多种逆境胁迫反应。泛素化修饰反应由3种关键酶协同作用完成。泛素分子通过与泛素激活酶的巯基酯键连接从而被激活,被激活的泛素分子再与泛素结合酶形成复合体,最后在泛素连接酶的作用下完成与靶蛋白的结合。随着蛋白质组学测序技术的不断发展,人们对泛素化修饰的研究更加普遍和深入。大量被泛素化修饰的蛋白及其修饰位点被鉴定出来,有助于深入了解蛋白质的调控机制,进一步解析蛋白质的功能。本文介绍了泛素-蛋白酶体系统的反应过程,泛素化修饰关键酶的结构、数量及分类,并重点围绕泛素激活酶、泛素结合酶和泛素连接酶在植物应对非生物及生物胁迫中的功能研究开展论述,同时也对植物泛素化修饰关键酶的功能研究所面临的问题进行总结,并对泛素化修饰与其他修饰之间的串扰进行了讨论与展望,对于泛素化修饰在植物逆境胁迫领域的深入研究具有重要意义。

The plane strain asymmetrical rolling was analyzed using slab method. The contact arc was replaced by parabola, and the constant surface friction status was adopted during the analysis. The deformation area was divided into three zones according to the direction of the friction. Then, the three zones were studied, respectively. A rolling force model and a rolling torque model were developed based on the analysis, and they were used to analyze the influ- ence of asymmetrical rolling factors on deformation area and unit pressure if they had good precision which was determined by comparing the calculated results with the measured ones.

The processing conditions of the texture formation and deep drawability of a Ti-IF steel strip hot-rolled in ferritic region and subsequently annealed were investigated. The r-value increases with the decrease of reheating temperature, and finish rolling temperature and the increase of reductions in ferritic region. For lubricated ferritic rolling and annealing, the r-value is raised up to 1.75, and elongation rate is over 50% at the finish rolling temperature of 650 ℃, which is suitable for DDQ grade products. However, the r-value is below 1.0 in the case of unlubricated rolling. The X-ray diffraction was used to analyze the textural characteristic of samples. For samples subjected to lubricated rolling and annealing, the strong { 111 }//ND recrystallization texture is distributed homogeneously along the thickness direction, and the intensity of { 110} recrystallization texture is very low even in surface. However, for unlubricated samples, the {111} texture is distributed inhomogeneously and is weak along the thickness direction, and （110}//ND recrystallization texture is strong, which deteriorates the formability.

The texture evolution of ferritic hot rolled Ti-IF steel during cold rolling was investigated in which the reduction was from 15% to 85 %. It was found that α fibre texture was monotonously intensified with the increase in the cold rolling reduction, while y fibre texture changed in a different way. When the cold rolling reduction was in the range of 15 % -- 35 % or 45 % -- 75 %, γ fibre texture was strengthened ; however, when the cold rolling reduction was 35 %- 45 % or 75 %- 85%, the intensity of 7 fibre was reduced. The 7 fibre displayed a maximum intensity for the reduction of 75%, and the highest average plastic strain ratio was simultaneously obtained owing to the favorable recrystallization texture.

The texture evolution in a high strength Ti-IF steel during the processing of hot rolling, cold rolling, and annealing is studied. For comparison, both ferrite rolling and austenite rolling are employed. It is found that the texture type is the. same after ferrite rolling and austenite rolling, but the texture intensity is much higher in the ferrite rolled sample. Furthermore, texture characteristics at the surface are absolutely different from those at the mid sec tion in both ferrite rolled and austenite rolled samples, as well as under the cold rolled and annealed conditions. The shear texture { 110 } 〈001 〉 disappears and orientation rotates along { 110 } 〈001 〉→ { 554 } 〈 225 〉→ { 111 } 〈 112 〉→{111}〈110〉→{223}〈110〉 during cold rolling. Compared to the austenite rolled sample, the properties of the cold rolled and annealed sheet which is subjected to ferrite rolling are higher.

Ablotlc stress, such as salt, drought and extreme temperature, can result in enhanced production of reactive oxygen species （ROS）. Plants have developed both enzymatic ROS-scavenging and non-enzymatic ROS-scavenging systems. The major ROS-scavenging enzymes of plants include superoxide dismutase （SOD）, ascorbate peroxldaae （APX）, catalaae （CAT）, glutathione peroxldaae （GPX） and peroxiredoxina （Prxa）. In the present work, we identified a gene encoding chloroplast-located peroxiredoxin Q, SsPrxQ, from Suaeda salsa L. located at chloroplast. Overexpression of SsPrxQ In Arabidopsis leads to an increase In salt and low-temperature tolerance.
