With the ever increasing scholarly exchange between Mainland China and the rest of the world, the environment of research in Mainland China has become more open and quality of research significantly enhanced. Consequently, the publication of primary research sources has also broadened in scope and extends further back into history. Research materials are published in more diverse genres and languages. This article intends to synthesize the trends in recent developments in the publication of research materials in Mainland China.頁次：84-88

通过粗粒化分子动力学模拟，在高分子链与纳米棒间的不同相互作用强度、不同高分子链刚性，且在同时考虑单分散和双分散共混高分子链条件下，研究了高分子链在纳米棒界面区域的吸附行为。对于柔性环形高分子链，增强高分子链与纳米棒间的相互作用有利于提高纳米棒对高分子链的吸附。当高分子链与纳米棒间的相互作用强度较弱时，增强高分子链刚性会诱导高分子链套在纳米棒上形成规则的自组装结构。对环/线高分子链共混情况，当高分子链与纳米棒间的相互作用较弱时，随着链刚性的增强，环形高分子链优先占据纳米棒界面区域；当高分子链与纳米棒间的相互作用较强时，随着链刚性的增强，纳米棒界面区域由优先吸附环形高分子链转为优先吸附线形高分子链。研究结果有助于进一步了解高分子链与纳米棒的复合材料，为改善纳米复合材料的性能提供理论支持。

[Objective] To explore the trade-off and synergistic relationship between land use and ecosystem services in Yidu City, and optimize this relationship through multi-scenario simulation.[Method]Multi-objective planning and patch generation land use simulation model (PLUS) were used to construct three future development scenarios.The land use structure, spatial layout and ecosystem service value of Yidu City under different scenarios in 2030 were evaluated using InVEST model. [Result] Under the scenario of low-carbon development, the land use structure of Yidu City was the most reasonable, the spatial layout was the most intensive, and the ecosystem service value was the highest. Compared to other scenarios, the low-carbon development scenario performed better in terms of coordination and sustainability between land use and ecosystem services. [Conclusion] The low-carbon development scenario provides the best coordination path between land use and ecosystem services in Yidu City. [ABSTRACT FROM AUTHOR]

Objective To investigate the therapeutic effect of cholesterol sulfate(CS)on the Hashimoto's thyroiditis mouse model. Methods Female NOD. H-2h4 mice were fed with 0.05% NaI in different periods and treated with CS by intraperitoneal injection for two consecutive weeks. HE staining was used to visualize and score the degree of lymphocyte infiltration in the thyroid; serum levels of thyroglobulin antibody(TgAb), thyroid peroxidase antibody(TPOAb), thyroxine(T4), and thyroid stimulating hormone(TSH)were detected by ELISA. The proportions of B cells and Treg, Th17, Th1, and Th2 cells were analyzed by immunofluorescence staining flow cytometry. Results HE staining showed that the inflammatory score of thyroid tissue in mice after intraperitoneal injection of CS in the 8-week group and the 16-week group decreased significantly(P<0.05). In the 64-week group, there was no significant difference between the treatment group and the induction group(P=0.31). Serological analysis showed that after CS intervention, the levels of TgAb and TPOAb in mice induced by 0.05% NaI significantly lowered(P<0.05)in the 8-week group and the 16-week group, while thyroid function(TSH and T4 levels)of the mice changed significantly only in the 16-week group. Flow cytometry analysis showed that in the 8-week group, after CS intervention the proportions of B lymphocytes and Th1, Th2, Th17 and Treg cells in mice were significantly changed(P<0.05). Conclusion CS has significant therapeutic and remission effects on the early and middle stages of Hashimoto's thyroiditis. [ABSTRACT FROM AUTHOR]

For the application service of weather real-time data, 1 km resolution multi-source fusion analysis grid product (ART_1 km) developed by the National Meteorological Information Center was used as the grid background field, and the meteorological element values of any coordinate point were obtained through interpolation. By adopting the FastAPI high-performance web framework and OAuth2. 0 open authorization standard, a weather live service (Weather LBS) was designed and implemented based on any location. After deployment testing, the results show that the service has fast response speed, high security, and is convenient to use. It is published according to the meteorological unified service interface community(MUSIC) standard and can be called by third-party applications to achieve real-time query of weather information at any location by users. This service has been applied to systems such as meteorological data access and weather WeChat mini programs for the 14th National Games, achieving good service results. [ABSTRACT FROM AUTHOR]

The mapping of soil properties based on mathematical model has the characteristics of high efficiency, high speed and low cost, which makes up for the deficiency of spatial interpolation which ignores the categorical or qualitative variables such as soil type, vegetation type and environmental factors closely related to soil properties. In order to improve the accuracy of soil properties mapping and reduce the influence of uncertain factors, it is a new idea to make rational use of categorical variables in continuous soil properties mapping. In this study, total carbon mapping of soil in Yushu City, Qinghai Province was taken as an example, and weighted variables were constructed by soil type, geomorphic type and other categorical variables together with DEM and NDVI respectively, to explore the feasibility and practicability of weighted variables in soil properties mapping. The results show as follows. (1) The total carbon content of the soil in Yushu City is 19.60—120.55 g·kg–1, the average is 55.80 g·kg–1, the standard deviation is 19.22 g·kg–1, and the coefficient of variation is 34.44%, which is a medium degree of spatial variability. (2) The weighted variable model is superior to the similar model established by the digital elevation model, slope, aspect and other conventional variables. The overall importance of weighted variable is higher than that of conventional variable. The importance of weighted variable constructed by geological type, soil type, vegetation type and DEM is much higher than that of DEM itself. (3) The all-variable multiple regression model is the best model to predict soil total carbon content. The cumulative importance of the weighted variables in the all-variable multiple regression model is 0.55, and the prediction results are in line with the geosciences law and actual situation in the study area. In conclusion, weighted variables are a new way to make effective use of classified variables, which provides a new method for obtaining soil properties mapping variables, and its feasibility and practicability have been verified to some extent in this study.

采用耗散粒子动力学模拟方法研究了刚柔三嵌段共聚物(coil-rod-coil，CRC)在溶剂环境下的自组装.通过观察C4R8C4共聚物囊泡结构形成的动力学过程，发现体系先自组装成球形或柱状胶束，然后逐渐融合为盘状结构，再进一步弯曲形变，形成闭合的双层膜囊泡结构.当共聚物浓度为6%〜25%时，C4R8C4自组装成不同尺寸的囊泡相，其均方半径〈D2〉随共聚物浓度的增加而增大，而双层膜厚度T基本保持不变.最后，改变溶剂性质，从亲棒到中性再到亲链，体系自组装结构从囊泡相转变为球形胶束相.尤其在等效的中性溶剂环境下，体系呈现层状结构，其中棒与棒嵌段呈高度有序的液晶相排列.
