Through sorting out the data of urban renewal units in Shenzhen from 2010 to 2016, this paper quantitatively analyzed the spatial characteristics of urban update from two dimensions of location conditions and functional attributes, using social network analysis, community discovery and other *** research found that:(1) the urban functional network formed based on the update unit had obvious spatial agglomeration and hierarchical characteristics, forming the central-peripheral structure of "two mains and five sections", covering basically all the developed areas of Shenzhen city, and presenting the overall spatial structure of "dense west and sparse east";(2) based on the functional space of urban update unit, five relatively closely connected community groups were formed, whose characteristics mainly included:spatial integration, spatial coupling and spatial spillover effect;(3) the spatial structure formed by urban updates basically conformed to the spatial structure defined in the plan of "the 10 master plan".

To the Editor:Osteoarthritis(OA)is a disease associated with high morbidity and ***,typically measured as a body mass index(BMI)≥30 kg/m2,is a well-known risk factor for the onset of OA and its related complications.[1]Interestingly,these two diseases may have common underlying mechanisms which contribute to the pathogenesis,such as genetic changes,and these mechanisms have not yet been fully *** expression profiling is a powerful tool used to systematically identify the molecular features underlying genetic variations associated with complex multifactorial diseases such as *** addition,it has been shown the significance of gene expression in understanding the mechanisms in the pathogenesis of obesity and OA.[2]This study hypothesized that hub genes could explain the relationship between obesity and ***,identifying that these genes are involved could provide insights into the detailed regulatory mechanisms of obesity on OA.

肝内胆管癌(ICC)是指起源于肝内二级胆管及其分支的腺癌,恶性程度高,预后差。根治性手术切除是目前可能治愈ICC的唯一方式,但只有部分患者符合手术指征,而即使进行了手术切除,也有约60%的患者会在1~2年内复发。新辅助治疗与辅助治疗是IC... 详细信息

肝内胆管癌(ICC)是指起源于肝内二级胆管及其分支的腺癌,恶性程度高,预后差。根治性手术切除是目前可能治愈ICC的唯一方式,但只有部分患者符合手术指征,而即使进行了手术切除,也有约60%的患者会在1~2年内复发。新辅助治疗与辅助治疗是ICC围术期重要的治疗手段,其目的是减少术后复发,改善术后生存。本文旨在阐述ICC的新辅助治疗和辅助治疗的现状及研究进展。

This study aimed to investigate the effect of varying pyrite(Py)content on copper(Cu)in the presence of different regrinding conditions,which were altered using different types of grinding media:iron,ceramic balls,and their mixture,followed by flotation in the cleaner *** flotation performance of rough Cu concentrate can be improved by changing the regrinding conditions based on the Py *** electron microscopy,X-ray spectrometry,ethylenediaminetetraacetic acid disodium salt extraction,and X-ray photoelectron spectroscopy studies illustrated that when the Py content was high,the use of iron media in regrinding promoted the generation of hydrophilic Fe OOH on the surface of Py and improved the Cu *** ceramic medium with a low Py content prevented excessive Fe OOH from covering the surface of chalcopyrite(Cpy).Electrochemical studies further showed that the galvanic corrosion current of Cpy-Py increased with the addition of Py and became stronger with the participation of iron media.

对鄂西晚二叠世地层划分的新认识

武汉工程大学学报 1992年第2期26卷 51-54页

作者：林昱宣武汉化工学院矿山系

在鄂西、松(滋)宜(都)地区松木坪原下三叠统大冶组底砾岩中,首次发现晚二叠世的旋齿鲨化石和火山碎屑物,从而把该层砾岩划归二叠系顶部,改称“顶砾岩”为好,在本区此层相当于大隆组,而把原长兴组划归吴家坪组上段。
