Angiolymphoid hyperplasia with eosinophilia (ALHE), also named epithelioid hemangioma (EH), is an inflamed vascular tumefaction of uncertain pathogenesis, characterized by proliferation of histiocytoid endothelial cells with prominent lymphocytic and eosinophilic infiltration. Although considered a benign condition, it may recur in up to one-third of cases in the absence of complete surgical excision. The pathogenesis of ALHE/EH is still controversial. However, reaction to trauma and arteriovenous shunting are considered relevant. Histologically, ALHE/EH may be differentiated from other vascular neoplasms by its several unique characteristics including prominent proliferation of plump endothelial cells, and accompanying eosinophilic and lymphocytic inflammation, often with formation of lymphoid follicles. Surgery is the mainstay of treatment and various other treatment strategies have been used with varying results.

A new marine hazard of golden tides caused by floating brown macroalgae-Sargassum occurred in the Yellow Sea in December 2016. An economic loss of 0.5 billion CNY (about 73 million USD) was estimated due to damaged seaweed aquaculture in the Jiangsu Shoal, China. In this study, images from the new Chinese satellite of Gaofen (GF) with high-resolution optical cameras are used to retrieve the drifting path of floating Sargassum and its origin. A southward drifting path of floating Sargassum in the western Yellow Sea is identified for the first time, and the initial site of bloom occurrence is near the eastern end of the Shandong Peninsula, China, implying the origin of this hazard of floating Sargassum. The scale of this Sargassum bloom event in the Jiangsu Shoal is also evaluated using a linear mixing model suitable for high-resolution images. The result shows that the total area of Sargassum-containing pixels in the GF-1WFV images on 31-Dec-2016 was more than 46 km 2 ; and according to the estimation by the linear mixing model, the total area of sea surface completely covered by Sargassum was above 8.8 km 2. The approach and the results presented in this work should contribute to future study and management of golden tides in Chinese coastal waters.

Urban agglomerations have become a new geographical unit in China, breaking the administrative fortresses between cities, which means that the population and economic activities between cities will become more intensive in the future. Constructing and optimizing the ecological security pattern of urban agglomerations is important for promoting harmonious social-economic development and ecological protection. Using the Harbin-Changchun urban agglomeration as a case study, we have identified ecological sources based on the evaluation of ecosystem functions. Based on the resistance surface modified by nighttime light (NTL) data, the potential ecological corridors were identified using the least-cost path method, and key ecological corridors were extracted using the gravity model. By combining 15 ecological sources, 119 corridors, 3 buffer zones, and 77 ecological nodes, the ecological security pattern (ESP) was constructed. The main land-use types composed of ecological sources and corridors are forest land, cultivated land, grassland, and water areas. Some ecological sources are occupied by construction, while unused land has the potential for ecological development. The ecological corridors in the central region are distributed circularly and extend to southeast side in the form of tree branches with the Songhua River as the central axis. Finally, this study proposes an optimizing pattern with "four belts, four zones, one axis, nine corridors, ten clusters and multi-centers" to provide decision makers with spatial strategies with respect to the conflicts between urban development and ecological protection during rapid urbanization.
