The study of carbon budget and carbon compensation zoning is of great significance in formulating strategies to adapt to the low-carbon development of each region, promoting synergistic management of regional ecological environment, and realizing high-quality develop‐ ment. This paper takes 56 municipal units in the Yellow River Basin as the study area, and by constructing a conceptual structure of carbon income and expenditure as well as carbon compensation zoning of the cities in the basin, it studies the spatio-temporal differentiation law of carbon income and expenditure as well as carbon compensation zoning of the urban agglomerations in the Yellow River Basin by using methods such as the centralization index and the location-con‐ strained multivariate spatial clustering, and then it provides constructive theoretical solutions for the low-carbon development strategy in the process of urbanization. The study shows that: (1) the cities in the Yellow River Basin from 2000 to 2020 are characterized by obvious geographical differentiation of carbon expenditure and revenue, specifically, the carbon expenditure and revenue centralization index of the study area fluctuates up and down around the warning line of 0. 4, and the overall curve shows an obvious fluctuating upward trend. (2) The spatial and temporal variation of carbon income and expenditure among cities in the Yellow River Basin is remarkable, and the data show that carbon emissions in the Yellow River Basin show a structure of "low in the west and high in the east and central parts of the country", with the high-value centres in Gansu, Shaanxi and Shandong provinces in 2000, and then the number of high-value areas of carbon emissions has increased year by year, while at the same time, the absorptive capacity of carbon sinks in each city is roughly equal. (3) Based on the framework of carbon offset zoning, the study area is divided into five types of carbon offset spatial optimization zones, and suggestions are made for green and low-carbon development planning in different types of zones. (4) In the future, the study will refine the spatial scale of the study area, explore the balance of carbon budget and carbon compensation of smaller units, and strive to explore the optimization of the green and low-carbon development mode of small areas, so that the energy conservation and emission reduction and green development of small areas can lead the cities in the region to achieve the dual-carbon goal.

Objective To evaluate clinical efficacy of artificial perfusion combined with interception basket in ureteral calculi lithotripsy. Methods Clinical data of 151 patients with ureteral calculi who underwent surgical treatment were retrospectively analyzed. They were divided into the observation group (artificial perfusion combined with interception basket) and control group (conventional perfusion pump) . The operation time, intraoperative blood loss, proportion of stone escape, stone re-intervention and complications were observed in two groups. Results There were no significant differences in operation time, intraoperative blood loss and incidence of complications between two groups (all P > 0.05) . The proportion of stone escape and stone re-intervention in the observation group were significantly lower than those in the control group, and the differences were statistically significant (both P < 0.05) . Conclusion Artificial low-pressure perfusion combined with interception basket in ureteral stone lithotripsy can reduce the proportion of stone escape and residual stone re-intervention and improve the stone clearance efficiency.

巨噬细胞是体内的一种固有免疫细胞，通过抗原提呈及吞噬作用，在人体免疫中发挥重要作用。巨噬细 胞的极化是巨噬细胞的显著特征，也是巨噬细胞在微环境中受到各种刺激因子发挥不同作用的基础。M1、M2表型 是巨噬细胞极化的两个方向，M1/M2极化的不平衡在炎症反应与疾病进展中起重要作用。巨噬细胞自身的物质代 谢可通过影响其极化状态来决定其不同的功能，葡萄糖、脂肪酸、氨基酸、铁、维生素等物质的代谢调控了自身极 化。细胞内代谢是一个完整同一的过程，各代谢途径间相互作用，存在复杂的调节机制，本文聚焦于巨噬细胞物质 代谢对自身极化的调控作用。巨噬细胞显示出不同的葡萄糖代谢类型，M1巨噬细胞以糖酵解为主，M2巨噬细胞则 利用氧化磷酸化供能。脂肪酸也能提供能量并参与了巨噬细胞的活化。精氨酸在 M1和 M2巨噬细胞内通过不同 的代谢方式产生不同的代谢产物，从而造成巨噬细胞功能的差异。巨噬细胞极化与铁代谢的差异调节密切相关，并 参与体内多种疾病的改变。维生素是巨噬细胞极化的重要调节剂。 [ABSTRACT FROM AUTHOR]
