新时代以来,我国公共政策的内容、过程、机制都有较为明显的变化,“五年规划”作为中国政策的核心,反映我国新时代公共政策特点的变迁。党和国家领导人关于规划建议说明稿为研究政府政策特点提供了分析素材。从内容分析和功能分析两个维度构建分析框架,对“九五”计划至“十四五”规划建议说明稿文本进行话语分析,可以发现新时代以来我国公共政策的科学化和民主化得到进一步提升,折射出政策的前瞻宏观性,总体呈现三大特点。在政策主体上加强主体间的上下联动,党的领导贯穿公共政策始终;在过程中走向决策流程规范化和制度化,问题导向与目标导向相结合;在结果上实现政策内容产出的均衡全面,政策学习更为积极主动。“五年规划”建议说明稿的话语变迁及其折射出的我国公共政策的特点变迁,受到内容性逻辑和任务性逻辑的双重影响。

Background In bypass surgery for moyamoya disease (MMD), the superficial temporal artery’s (STA) pressure needs to surpass that of the cortical M4 recipient of the middle cerebral artery (MCA), boosting cerebral blood flow into the MCA and enhancing cerebral circulation. This study investigates the STA-MCA arterial pressure parameters and gradients during bypass surgery, aiming to deepen our understanding of hemodynamic shifts pre- and *** DSA imaging data were prospectively collected from patients diagnosed with bilateral MMD who underwent STA-MCA bypass surgery between 2022 and 2023 and stratified according to the Suzuki stage. The mean arterial pressure (MAP) of the donor and recipient arteries was directly measured during the STA-MCA bypass procedure, and these data were statistically analyzed and *** Among 48 MMD patients, Suzuki grading revealed that 43.8% were in early stages (II and III), while 56.2% were in advanced stages (IV, V, and VI). Predominantly, 77.1% presented with ischemic-type MMD and 22.9% with hemorrhagic type. Pre-bypass assessments showed that 62.5% exhibited antegrade blood flow direction, and 37.5% had retrograde. The mean recipient artery pressure was 35.0 ± 2.3 mmHg, with a mean donor-recipient pressure gradient (δP) of 46.4 ± 2.5 mmHg between donor and recipient arteries. Post-bypass, mean recipient artery pressure increased to 73.3 ± 1.6 mmHg. No significant correlation (r= 0.18,P= 0.21) was noted between δP and Suzuki *** Our study elucidated that cerebral blood pressure significantly decreases beyond the moyamoya network at the distal M4 segment. Furthermore, we observed bidirectional flow in MCA territories and a significant positive pressure gradient between the STA and M4 segments. The lack of correlation between Suzuki stages and M4 pressures indicates that angiographic severity may not reflect hemodynamic conditions before surgery, highlighting the need for customized surgical appr

C/O能谱测井是确定含油饱和度的主要测井方法,在随钻条件下可以通过记录非弹性散射伽马能谱,根据C/O值来确定原始地层的含油饱和度。利用蒙特卡罗方法模拟水平井条件下不同岩性、孔隙度、饱和度、井眼尺寸、钻井液性质以及钻井液侵入、地层水矿化度、泥质含量、油气类型和源距时的非弹性散射伽马能谱,研究C/O值与含水饱和度、孔隙度的关系以及各种因素对测井响应的影响。在水平井条件下C/O值与含水饱和度呈线性相关,油基钻井液和石灰岩地层的C/O值大;井眼尺寸越小、地层水的矿化度越高、骨架中泥质越多以及源距越大时,地层的C/O值越大;钻井液侵入随着侵入深度、岩性、孔隙度和钻井液类型的不同对C/O的影响规律不同。钻井液侵入越浅、井眼尺寸越小、孔隙度越大、油质越重,利用C/O能谱测井识别地层流体越有利。
