The Endometrial Cancer (EC) is the most common gynecologic malignancy that starts in the endometrium of women. Carcinogenesis of EC is associated with several critical regulatory molecules, which involve in different signaling pathways. A number of signaling pathways have been identified to be involved in the multiple-step development of EC, including PI3K/AKT/mTOR signaling pathway, WNT/β-catenin signal transduction cascades (including APC/β-catenin pathway), MAPK/ERK pathway, VEGF/VEGFR ligand receptor signaling pathway, ErbB signaling pathway, P53/P21 and P16INK4a/pRB signaling pathways. This review mainly focuses on the molecular signaling pathways relevant to human endometrial cancer and discusses those critical capabilities of transforming endometrial cells, including evading apoptosis;enhancing cell proliferation;blocking differentiation;and inducing angiogenesis.

金属空气电池的负极与电解液在停机期间一直接触发生腐蚀反应,这严重影响了金属空气电池的保质期。通过对常规金属空气电池结构简单改进,利用启普发生器原理解决金属空气电池的停机腐蚀问题。以铝箔为负极搭建结构改进前后的金属空气电池单池进行间断性恒流放电来测试电池停机寿命,并通过失重实验、析氢损耗测试实验对电池负极的停机腐蚀情况进行定量研究。结果显示,当负极为0.25 mm厚铝箔时,金属空气电池结构改进前后的停机寿命分别为4和21 d;改进结构后的金属空气电池负极在相同时间内的停机腐蚀量远小于常规金属空气电池负极;对单池而言,产生固液分离所需的氢气只需要消耗约0.0380 g的铝,约为一般商用铝负极的0.038%。

“中国式现代化”“中华民族伟大复兴”是分别从中国现代化史、中华民族发展史视角提出的既有联系又有区别的两个概念，均生成于改革开放初期。两大话语有“分”,有着相对独立的酝酿、生成、建构过程：“中国式现代化”概念在上世纪70年代末提出后大致呈现为出场——退场——重启的脉络，被写入党代会报告已到了40余年后的中共二十大；“中华民族伟大复兴”语词在上世纪80年代初出现报章后，很快即被写入十三大报告，并一路攀升为高频使用的热门词。又有“合”,体现为社会主义初级阶段历史定位、中国特色社会主义总任务、新征程中国共产党中心任务与实现伟大梦想“关键在党”表述上的“四个耦合”。有必要在整合以往现代化话语(“工业化、四个现代化、社会主义现代化”)与民族复兴话语(“站起来、富起来、强起来”)的基础上，建构“以中国式现代化推进中华民族伟大复兴”的历史叙事。

Purpose:To investigate the association between high anisometropia and the area of choroidal neovascularization (CNV) induced by krypton laser in guinea pigs and better understand the pathogenesis and prevention of myopic CNV. Methods:.Nine 3-week old male guinea pigs with anisometropia > 6.00D were randomly assigned to three groups according to examination date after laser photocoagulation (7d, 14d and 28d). All animals underwent refraction. The eye with higher myopia was used as the experimental eye, and the other as the control eye..All eyes received repeated multi-wavelength krypton laser photocoagulation treatments (wavelength: 532 nm; laser power: 400 mW; spot diameter: 50 μm; exposure time: 0.1s). Fundus photography and indocyanine green angiography (ICGA) were performed. Afterwards, the animals were sacrificed immediately,.and the eyes were enucleated and processed for histopathologic examination and flat mounts. Results: CNV appeared at 7d after laser treatment. The area of CNV peaked at 14d, and decrease in area and the presence of scarring was noted at 28 d..CNV was present in 66.7% of eyes by ICGA at 14 d..CNV could be observed under light microscopy at all three time points..At 14 d,.flat mount showed the neovascular plexus around the lesion. Semi-quantitative analysis revealed that the area of CNV in treated eyes was greater than that of control eyes. Conclusion:.Since the mechanism of CNV in this study resembles that of CNV in pathological myopia, this model can be used to investigate the etiology, pathogenesis and treatment of CNV in pathological myopia.

青藏高原东北部新生代构造演化对理解高原隆升和变形模式具有重要意义,而目前对于该地区挤压应力方向转变过程仍存在很大争议.本文对柴北缘逆冲带北西部骆驼泉剖面新生代地层开展系统磁组构(本文特指磁化率各项异性)研究,以揭示该地区挤压应力方向的转变特征.系统岩石磁学结果表明,骆驼泉剖面新生代样品中主要磁性矿物是顺磁性组分和赤铁矿以及少量磁铁矿.通过对磁组构特征分析及其与古水流方向对比表明,骆驼泉剖面新生代地层磁组构主要为初始变形磁组构,可用于指示沉积成岩时期的挤压应力方向.磁组构结果揭示,骆驼泉地区挤压应力方向在上干柴沟组下部沉积时期为NNE-SSW向,而上干柴沟组上部和油砂山组沉积时期转变为NE-SW向.结合柴北缘逆冲带已有磁组构结果指出,该地区早期N-S向或NNE-SSW向挤压应力可能与印度—欧亚板块早新生代以来近N-S向碰撞挤压过程有关,指示印度—欧亚碰撞的挤压应力自下干柴沟组下部沉积时期就已传播至高原东北部地区;而后期NE-SW向挤压应力方向与该地区现今GPS揭示的上地壳运动方向一致,可能与该时段高原东北部巨型走滑断裂构造体系(尤其是阿尔金断裂)有关.此外,柴北缘逆冲带新生代挤压应力方向转变在其北西部起始于上干柴沟组下部沉积时期,而南东部起始于上油砂山组下部沉积时期,与地震反射剖面揭示的断裂活动等地质证据共同揭示柴北缘逆冲带新生代的构造活动自靠近阿尔金断裂的北西部向南东部传播和扩展.综合分析青藏高原东北部地区挤压应力方向转变和其他地质证据发现,挤压应力方向转变显示出自柴北缘逆冲带北西部向东、西和南向扩展特征,与阿尔金断裂在上干柴沟组下部-上油砂山组下部沉积时期剪切应力集中于断裂本身,而上油砂山组下部沉积以来开始散布于高原东北部内部地区的两阶段走滑活动相关.
