Macrophage is the key innate immune effector in first-line defense against the pathogens, and can be polarized into different phenotypes to regulate a variety of immunological functions. However, the plasticity of macrophage is extraordinarily recruited, activated, and polarized under pathological conditions,playing paramount roles in occurrence, development, and prognosis of various chronic diseases, such as rheumatoid arthritis(RA), atherosclerosis(AS), and cancer. To this end, macrophage has become an important therapeutic target for etiological treatment of these diseases. Meanwhile, with the development of nanotechnology, various nano-drug delivery systems have been explored to target macrophages for disease modulation, displaying unique advantages to address both pharmaceutic and biopharmaceutic limitations of various drugs. This review aims to summarize the recent progress of macrophage-targeted nanomedicine for chronic diseases immunotherapy. First, the origin, polarization and biological functions of macrophages have been introduced, in which macrophages can differentiate into different phenotypes in response to physiological stimuli to play various immunological roles. Then, the macrophage disorder has been reviewed in related with various chronic diseases, and several representative diseases, including AS, RA, obesity, and cancer, have been discussed in detail to elucidate the pathological contributions of macrophages for disease progress. Next, strategies to regulate macrophages for diseases immunotherapy, such as macrophages depletion, macrophage reprograming, inhibition of macrophage recruitment,are summarized, and particular attention has been paid on bio-functional nanomaterials to engineer macrophages via different mechanisms. Further, methods for macrophage-targeting delivery nanosystems are discussed based on both passive and active targeting approaches. Finally, the perspective is speculated for potential clinical translation, and there still has

【目的】寻找阳光玫瑰葡萄理想安全的破眠方法以及探究其破眠机制。【方法】以阳光玫瑰葡萄冬芽为试材,通过研究类休眠阶段和生理休眠阶段不同破眠处理对葡萄萌芽率、成花率和花穗质量的影响,并通过转录组测序筛选可能影响葡萄冬芽萌发的关键基因。【结果】在萌芽前1个月对阳光玫瑰葡萄冬芽进行单氰胺处理、石硫合剂+1-氨基环丙烷羧酸(ACC)处理,均能使萌芽提前,显著提高萌芽率,不影响成花率及花穗质量。通过分析转录组数据,筛选了PYL4、PP2C24、PP2C8、PP2C37、PP2C25、SAPK2等差异表达基因,这些基因可能通过参与激素信号传导、氧化应激等途径影响葡萄芽的萌发。【结论】5°Bé石硫合剂+0.25 mg·mL-1ACC是阳光玫瑰葡萄打破休眠的一种安全、有效的处理方法。

Vascular smooth muscle cell(VSMC) proliferation and migration are pivotal for the pathogenesis of atherosclerosis and post-angioplasty restenosis. We have recently reported that a disintegrin and metalloproteinase with thrombospondin motifs-7(ADAMTS-7), a novel metalloproteinase, contributes directly to neointima formation by mediating VSMC migration. However, whether ADAMTS-7 affects VSMC proliferation remains unclear. In this study, we found that luminal adenoviral delivery of ADAMTS-7 aggravated intimal hyperplasia 7 d after injury, paralleled by an increased percentage of PCNA-positive cells in both intima and media. In contrast, perivascular administration of ADAMTS-7 si RNA, but not scrambled si RNA to injured arteries attenuated intimal thickening at day 7, paralleled with reduced intimal VSMC replication, without alteration of VSMC proliferation in the media. In accordance, [3H]-thymidine incorporation assay in primary cultured rat VSMCs revealed an enhanced replication rate(by 61%) upon ADAMTS-7 overexpression and retarded proliferation(by 23%) upon ADAMTS-7 si RNA administration. Our data demonstrates that ADAMTS-7 promotes VSMC proliferation both in vitro and in vivo. ADAMTS-7 may therefore serve as a novel therapeutic target for atherosclerosis and post-angioplasty restenosis.

随着“一带一路”倡议的推进,中国海外利益的范围和深度正在迅速拓展.中国企业公民“走出去”成为常态,如何保护他们安全与合法权益已经成为中国外交不容回避的重要课题。警务外交正是应运而生的一种海外利益保护的新手段。本文尝试从警务外交的概念切入,探讨警务外交在当今时代背景下的特殊意义,并在分析当前海外利益保护现状的基础上,从深入发展职业外交、拓宽执法合作渠道、加强专业技术合作、推进国际执法话语权建设等方面提出强化警务外交的现实路径,呼唤进一步发挥警务外交的作用,以回应我国急剧增长的海外利益保护需求。

难民问题是长期存在的，在中东地区尤为明显。在全球治理中，国际社会通过多层次、多领域的合作，取得了明显的成效。然而一些障碍性因素的存在使得这一问题难以从根本上得到解决。在这个问题上中国与西方国家不同，西方国家一般注重问题表面治理，而中国更加注重的是根本问题的解决。中国在中东难民问题治理中，通过单边援助与双边对话以及多边会议等多重机制在解决中东难民问题上发挥着不可替代的作用。
