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.

The push-pull framework provides a useful approach for examining the tourist motivation. This paper takes the world heritage-Huangshan Mountain as a sample. From the two different aspects of pull and push factors, the underlying features of visitors′ motives to Huangshan Mountain are analyzed with the help of factor analysis. As a result, five push factors and four pull factors are identified. Further analyses investigate differences in the push and pull factors among different socio-demographic subgroups with one-way ANOVA analysis. The result of the study affords us useful references for development, protection and marketing expansion of mountain resorts.

The title complex [(ArO)2(THF)Sm(μ-OH)]2?2THF (Ar = C6H2-tBu3-2,4,6) was obtained by the hydrolysis of divalent (ArO)2Sm(THF)3?THF in toluene. It crystallizes in monoclinic, space group P21/c with a = 14.7968(14), b = 18.6981(15), c = 16.8264(17) ?, β = 109.366(2)°, V = 4392.0(7) ?3, Z = 2, C88H150O10Sm2, Mr = 1668.78, Dc = 1.262 g/cm3, F(000) = 1764 and μ(MoKα) = 1.377 mm-1. The final R and wR are 0.0318 and 0.0749, respectively for 9038 observed reflections with I > 2σ(I). The complex possesses a dimeric structure with two centrosymmetric hydroxyl bridges. The samarium atom is coordinated by five oxygen atoms to form a distorted square pyramidal geometry with the average Sm–O(Ar) distance of 2.1757(19) ?. There are H-bond interactions be- tween the molecules.
