地方主导型产业政策加深了“行政区经济”的市场壁垒和地方保护,严重阻碍全国统一大市场建设。当前迫切需要以中央主导型产业政策推进全国统一大市场建设。重点方向是通过缓解要素市场和中间品市场交易壁垒来降低生产端的市场交易成本,通过缓解商品市场分割来降低消费端的市场交易成本。中央主导型产业政策推进全国统一大市场建设,具体在于促进要素自由流动和公平竞争,消除地方政府使用产业政策搞“自我小循环”的各种因素;充分发挥中央主导型产业政策的“统一”作用,降低地方主导型产业政策的“分割”性;积极推动地方政府之间的沟通交流,将区域协调发展战略的实施作为开展全国统一大市场建设的推进器。

Infiltration by monocytes of the central nervous system and its role in multiple sclerosis: reflections on therapeutic strategies

Neural Regeneration Research 2025年第3期20卷 779-793页

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

用传播的方式促进从生产到消费转换的行为皆为存在意义上的广告,广告的本体是本质与价值的统一。本体的坚守要建立开放的认识观,在不变的广告本质中解释变化着的广告形态,而非用未触及本体的不确定认识窄化新的广告事实。彰显广告价值需深耕数字广告实践,用创意提升广告的社会吸引力,建构多主体参与的沟通网络。彰显广告价值还需要在理论层面,以本体观为支点,立足于本土广告实践,重新组织数字广告研究范畴,使用大数据技术与混合研究法探究新问题,为广告学知识体系的建构提供框架与方向。

Analytical model test of methods to find the geometry and velocity of magnetic structures

It is important to determine the dimensionality and velocity information in the study of spatial magnetic structures. Many data analysis theories/techniques are based on the assumption of one or two dimensions. For example, the Grad-Shafranov(GS)reconstruction method assumes a dimensionality of two or less. The Minimum Direction Derivative(MDD) method provides an indication of the dimensionality. For the structure velocity, the components in each dimensionality can be calculated by SpatioTemporal Difference analysis(STD). In order to improve the convenience of use of MDD method, a new parameter Dm quantifying the dimensionality based on MDD eigenvalues is introduced in this paper. The influences of noise/turbulence,separation distance and tetrahedron configuration on MDD and the evaluation of Dmare systematically tested using two analytical models for magnetic structures, representing a magnetic mirror and magnetic flux rope. We tested and gave the threshold values of three quality indicators for MDD results using the flux rope model. We also show that the error induced by turbulence is comparable to that of random noise when the turbulence scales are less than the spacecraft separation. Besides, the accuracy of STD velocity estimation will also be influenced by turbulence for cases with excessively high data time *** using Dm, we show that an ideal model of a mirror-like structure can be divided into one dimension(1-D) and three dimension(3-D) regions. This restricts the applicability of the GS method in mirror-like structures. For example, in a given reconstruction range, the GS error increased from less than 7% to more than 15% by using the data along trajectories in 1-D and 3-D regions as predicated by Dm. Thus, it is important to estimate the structure dimensionality, which can be further used to estimate the reliability of the GS reconstruction map.
