简介：画院与院画,是两个既密不可分,又各有指向的概念。前者多指画院机构机制,后者多指与画院有关的画家、画作、画风。两宋绘画之所以臻造中国绘画之鼎盛,与当时的画院机制关系密切;研究两宋乃至元明绘画,也不能绕开南宋院画。院画是相对文人画而言的一种画体,有时特指画院画家的作品。南宋定鼎临安,杭州相应地成为文化艺术新都,高宗重建画院,广征艺术人才,院画遂重新焕发生机,并呈现出对北宋绘画有承有变的特色。

简介：摘要：房屋建筑对于人们来说至关重要，但房屋建筑在经过长时间使用后，其质量必然会下降，尤其是混凝土结构会逐渐发生改变，如果不及时修缮，不仅会缩短房屋建筑的使用寿命，还会导致其功能无法实现。因此，本文以上海市第一妇婴保健院西院整体大修项目2号楼修缮工程为例，对结构加固技术在建筑工程中的应用进行分析，希望为相关行业提供借鉴。

简介：AbstractPlacentation and tumorigenesis have many common features. Human placentation builds a maternal-fetal connection, circumvents maternal immune rejection of the fetus, and utilizes mechanisms that support tumorigenesis, such as proliferation, invasion, angiogenesis, and immune tolerance. Trophoblasts of the human placenta mimic the behavior of malignant cells, proliferating and invading the uterine decidua until reaching the myometrium and remodeling the spiral arteries that establish a new vascular system and escape the maternal immune response. These processes are under precise temporal and spatial regulation, and their dysregulation is associated with different pregnancy syndromes, including preeclampsia (PE), a pregnancy syndrome that is the leading cause of maternal and perinatal mortality and morbidity. At present, the precise mechanisms underlying the development of PE remain unclear. Here, we summarize and dissect the features between physiological placentation and pathological tumorigenesis to explore the pathogenesis of PE - which we believe to be the result of insufficient placentation, compared to the overaggression of tumorigenesis - to provide novel strategies to prevent and treat PE.

简介：AbstractBackground:The dermoscopic features of rosacea have already been reported. However, the current findings are incomplete, and little is known about phymatous rosacea. Hence, this study aimed to summarize and compare the dermoscopic features and patterns of three rosacea subtypes (erythematotelangiectatic [ETR], papulopustular [PPR], and phymatous [PHR]) in the Chinese Han population and to evaluate whether these features differ with patients’ genders, ages, and durations.Methods:Dermoscopic images of 87 rosacea patients were collected in non-polarized and polarized dermoscopy contact modes at 20-fold magnification. Dermoscopic features, including vessels, scales, follicular findings, and other structures, were summarized and evaluated.Results:The reticular linear vessels and red diffuse structureless areas of ETR were distinctive. For PPR, red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules were typical dermoscopic criteria. The common dermoscopic features of PHR were: orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines. The following features statistically differed among the three rosacea subtypes: reticular linear vessels (P < 0.001), unspecific linear vessels (P= 0.005), linear vessels with branches (P < 0.001), yellow scales (P = 0.001), follicular plugs (P < 0.001), perifollicular white color (P < 0.001), red diffuse structureless areas (P = 0.022), orange diffuse structureless areas (P < 0.001), red focal structureless areas (P = 0.002), orange focal structureless areas (P = 0.003), white lines (P < 0.001), follicular pustules (P < 0.001), and black vellus hairs (P < 0.001).Conclusions:The dermoscopic patterns of ETR are red diffuse structureless areas and reticular linear vessels. For PPR, the pattern comprehends combinations of red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules. Meanwhile, PHR is characterized by remarkable orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines.
