关键词： 肿瘤相关抑郁   柴胡类方   理论   临床应用  

摘要： 随着我国肿瘤发病率不断高发,肿瘤年轻化趋势正在上升,随之肿瘤引起的相关抑郁也在不断蔓延。近年来,许多文献报道临床运用柴胡类方治疗肿瘤相关抑郁取得良好疗效。在中医学中,肿瘤相关抑郁可归为“郁证”,认为郁证以机体气机异常变化为主,而柴胡类方剂以调节少阳气机为主。基于此,本文围绕《内经》“凡十一藏取决于胆”以及三焦展开探讨,以揭示柴胡类方治疗肿瘤相关抑郁的理论依据,并分析柴胡类方剂的涵义及临床应用,以期为临床提供依据。

摘要： A total solar eclipse occurred on April 8, 2024, across the United States, with obscuration rates ranging from 20-100% at different locations. We study the ionospheric Total Electron Content (TEC) response to the eclipse using data from 51 ground-based GPS stations. We find a significant depletion in TEC of up to 65%, with larger depletion rates occurring along the path of totality. We also observe a time delay between the maximum TEC depletion and the time of maximum obscuration, ranging from 8 to 80 minutes, with longer delays occurring at stations with lower obscuration rates. Both time delay and TEC depletion rates are found to vary with latitude, with slightly longer delays at lower latitudes and higher TEC depletion rates at mid-latitudes. The TEC depletion rate also increased with local time, showing a higher decrement after noon compared to before. The spatiotemporal variation in TEC closely followed the eclipse's path, indicating a positive correlation with the movement of the moon's shadow. Monitoring rate of TEC change during such rare events is crucial for enhancing our understanding of ionospheric dynamics, which can be very helpful to improve the accuracy of global communication and navigation systems.

摘要： We present light curve solution of V458 Mon firstly by using the Wilson-Devinney code. The total eclipse and deep minima of the light curves of V458 Mon enable us to determine reliable orbital parameters of the binary system. The solution suggests that V458 Mon is a low mass ratio binary system with about 0.2 possessing a moderate degree of contact. The long-term period investigation showed that the period of V458 Mon is increasing at dP / dt = +2 . 59 x 10 -7 days / yr, which could be the reason of mass transfer from the less massive component to more massive primary one, together with a periodic change. The oscillation in orbital period may be due to an unseen tertiary companion with the mass about M 3 = 1 . 8 M ae . After removing these change, there is still a weak cyclic change maybe due to magnetic activity. With the increase in orbital period of binary, the separation increases and mass ratio decreases which eventually leads V458 Mon towards merger.

摘要： Resonant orbits (ROs) within the Earth-Moon system exhibit periodic motion characterized by a simple integer relationship with the lunar period. These orbits hold significant applications for space situational awareness and the design of transfer orbits in cislunar space. However, due to the expansive scale and extended periods associated with Earth-Moon ROs, the resulting eclipse durations often exceed spacecraft power and thermal system capabilities. This paper conducts an analysis of shadow distribution and eclipse durations within the Earth-Moon 3:2 resonant orbit family. The investigation utilizes relative velocity with respect to the lunar shadow, highlighting the imperative need for eclipse mitigation. The study then proceeds to derive eclipse mitigation methods, specifically employing cross-track maneuver and phasing maneuver techniques. These strategies are applied to mitigate and avoid both Earth and lunar shadows, considering different initial solar phases and eclipse occurrence locations. Simulation results conducted within the circular restricted three-body problem (CRTBP) indicate that the eclipse mitigation strategy via cross-track maneuver incurs a lower Delta V\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\Delta V$$\end{document} cost, remaining within the range of 20 m/s. Furthermore, the stability of the resonant orbits post cross-track maneuver is examined.

摘要： Mitigating solar eclipses presents a formidable challenge in the design of spacecraft orbits, particularly in the case of a distant retrograde orbit (DRO), which is susceptible to significant solar eclipse threats. This paper undertakes a comprehensive analysis of the occurrence characteristics and patterns of both Moon and Earth eclipses on a DRO. The proposed approach involves a two-stage design procedure, encompassing initial orbit selection and orbit extension. The initial orbit selection method primarily focuses on mitigating Earth eclipses by employing the out-of-plane motion inherent in a DRO. The study meticulously explores the influence of three pivotal elements - amplitude, period, and initial phase - on the efficacy of Earth eclipse avoidance. Concurrently, when faced with unavoidable solar eclipses of the initial orbit, a series of tiny maneuvers are systematically applied to extend the baseline orbit. The parameter design space is discretized, and a tree search method is employed to identify viable maneuver sequences. The research successfully achieves the long-term stabilization of the baseline DRO, ensuring that solar eclipses do not exceed 2 h in 10 years. The proposed method's robustness and applicability are substantiated through validation under the ephemeris model.

摘要： Solar activities play an important role in the variation of the Atmospheric Electric Field (AEF), and affect the Global Electric Circuit (GEC). The relationship between the variation of the AEF and solar activities is focused in the present study. It includes the variation in the AEF with respect to sunspot numbers, direct and indirect radiations, and solar flares during the decline phase of solar cycle 24 from 2015-2019 for Islamabad (ISL) observatory in detail, and partially for Muzaffarabad (MZF) observatory. A few of them had good relationship with the atmospheric electric field. The solar eclipse effect on the atmospheric electric field for the Muzaffarabad station is also presented in this work. A significant increase was observed during the eclipse period which led to decrease in electrical conductivity of atmospheric electric field as compared to alternate days for the same period.

摘要： 建设新型智慧城市是提高治理能效、推进数字化发展的必然选择。评价新型智慧城市建设效率是衡量实际建设效果、识别短板与重点的关键，能为高效推进智慧城市建设提供依据。基于投入-产出视角构建新型智慧城市建设效率评价指标体系，并结合内生方向距离函数和两期卢恩伯格分解指数，分析山东省16个地级市在2019—2022年间新型智慧城市建设绩效水平及其变动。研究发现：全省整体的建设效率较高但部分城市呈明显下降趋势，城市层面效率差异逐渐扩大，投入资源利用率普遍不高，产出维度技术退步是使效率逐年退步的主因。基于此，提出了强化效率导向性评估、优化统筹协调机制和加强区域技术创新合作的政策建议。
