为了探讨较大长宽比的超高层框-筒结构加强层数量的确定以及加强层构件的布置，并得到既能满足结构需要、又尽量降低由加强层引起结构竖向刚度和内力突变的不利影响的加强层布置方案，以青岛海天中心T2塔楼作为研究对象，基于ETABS软件建立三维结构模型进行分析。在对比了传统原则布置加强层方案和改进方案后，提出基于该结构的一种较大长宽比超高层框筒结构加强层的设置原则：在刚度较小的方向上布置伸臂桁架和腰桁架，刚度较大的方向不布置伸臂桁架，只布置一跨或两跨腰桁架，这样布置既能满足结构对侧移和层间位移角的需求，又能使层间位移角突变和内力突变降低，同时减小加强层处两主轴方向的刚度差异，对结构最有利。

Based on the FVCOM three-dimensional finite volume ocean model, combined with the Jelesnianski empirical wind field model and ECWMF background wind field superimposition to form a synthetic wind field, the hydrodynamic characteristics of the Liaoning coast of the North Yellow Sea during the transit of Typhoon "Rumbiya" were studied, and the influence of different typhoon parameters such as typhoon track, moving speed, maximum wind radius, central pressure, and maximum wind speed on storm surge in the Northern Yellow Sea was analyzed. The results show that, the extreme storm surges decreases with the westward shift of typhoon track in the study area. With the increase of typhoon moving speed, the extreme storm surges reduces, and the duration of high water level decreases significantly. The extreme storm surges and the duration of high water level increases with the increase of the radius of maximum wind speed. The extreme value of storm surge is positively correlated with the maximum wind speed, and the change of the maximum wind speed has no obvious effect on the duration of high water. The storm surge increases as the central pressure decreases. The study results can provide some reference for storm surge disaster protection along the Liaoning coast of the North Yellow Sea.

Objective To explore the lipid-lowering effect of Qige Decoction before and after compatibility through the combination of pharmacodynamics and liver metabolomics, and to provide new research strategies for exploring the scientific notation of traditional Chinese medicine compatibility. Methods According to the pharmacodynamic strategy, three groups of drug administration were set up as Qige Decoction group, Astragali Radix-Puerariae Radix group, and Pericarpium Citri Tangerinae group. Four indices of blood lipids, serum biochemical indicators, and liver morphology and pathology were used to evaluate the intervention effect of Qige Decoction on hyperlipidemic rats. Liver metabolomics technology was used to analyze the effects of Qige Decoction on metabolites before and after compatibility, and multivariate statistical analysis was used to evaluate the differences between groups in terms of differential metabolites and metabolic pathways. Results Compared with the model group, the callback abilities of four indices of blood lipid in the Qige Decoction group were higher than those in Astragali Radix-Puerariae Radix group and Pericarpium Citri Tangerinae group, among which the total cholesterol (TC) and triglyceride (TG) levels in the Qige Decoction group decreased (P<0.05). A total of 86 potential biomarkers were identified by liver metabolomics, with 23, 13, and 7 metabolites being significantly different in the Qige Decoction group, Astragali Radix-Puerariae Radix group, and Pericarpium Citri Tangerinae group, respectively (P<0.05). Metabolic pathway analysis of 29 specific biomarkers with significant callback effects showed that they were related to glycerophospholipid metabolism, linoleic acid metabolism, α-linolenic acid metabolism, sphingolipid metabolism. arachidonic acid metabolism, and unsaturated fatty acid biosynthesis. Qige Decoction mainly regulates glycerophospholipid and linoleic acid metabolism, and uniquely acts on sphingolipid metabolism. Conclusion Qige Decoction has more lipid-lowering targets after compatibility, with better lipid-lowering effects than the Astragali Radix-Puerariae Radix group and Pericarpium Citri Tangerinae group. This study provides experimental evidence and research strategies for further revealing the scientific notation of traditional Chinese medicine compatibility. [ABSTRACT FROM AUTHOR]

The prediction of subway passengers' walking time during exit is an important basis for urban traffic operation and management. Accurate prediction can help alleviate subway congestion, optimize subway services, and improve passenger satisfaction. Firstly, video analysis software was used to extract the walking time and several characteristic variables of passengers during exit from surveillance videos. Secondly, in order to screen out the factors that have a significant impact on walking time, correlation analysis and optimal scaling regression model were used for factor analysis, and genetic algorithm was used to extract the optimal feature combination. Finally, the extracted features were used as input vectors and the Extreme Gradient Boosting model was used to predict walking time, with mean absolute error as the evaluation index. The experimental results show that the method proposed in this paper has good effect in predicting the behavior of subway passengers during exit, with a mean absolute error of 1. 55 s, lower than the unoptimized Extreme Gradient Boosting model (1. 87 s), support vector machine (2. 03 s) and random forest (1. 96 s) models.

目的 对比观察胸腔镜手术和开胸手术用于Ⅲ型先天性食管闭锁 (CEA) 的治疗效果。方法 Ⅲ型CEA 患儿139例, 按手术方式的不同分为开胸手术组75例和胸腔镜手术组64例。开胸手术组接受开胸手术治疗, 胸腔 镜手术组接受胸腔镜手术治疗, 记录并比较两组患儿的手术时间、手术切口长度、术中出血量、呼吸机辅助通气时 间、重症监护时间、术后完全肠内营养时间、术后完全肠内营养奶量热卡、胸腔引流管留置时间、住院时间等资料, 以 及肺部并发症、胸壁畸形、吻合口瘘、气管软化、复发性气管食管瘘 (rTEF) 等术后并发症发生情况。结果 139例患 儿均通过手术治疗完成食管闭锁和气管食管瘘修复, 其中135例患儿顺利康复出院, 4例患儿死亡, 开胸手术组和胸 腔镜手术组各2例。胸腔镜手术组手术切口长度、术中出血量、呼吸机辅助通气时间、重症监护时间、术后完全肠内 营养时间、胸腔引流管留置时间、住院时间均低于开胸手术组 (P均<0. 05), 而手术时间、术后完全肠内营养奶量热 卡均高于开胸手术组 (P<0. 05)。胸腔镜手术组肺部并发症发生率、胸壁畸形发生率均低于开胸手术组 (P 均< 0. 05)。结论 胸腔镜手术和开胸手术治疗Ⅲ型CEA的疗效相当, 但胸腔镜手术治疗Ⅲ型CEA具有手术创伤小、术 后恢复快、术后并发症发生率低的优点。 [ABSTRACT FROM AUTHOR]

目的　探讨高血压患者住院期间血压波动性与左心室肥厚 (LVH)的关系。方法　选择原发性高血压患 者2 110例。采用独立于均值的变异性 (VIM)、平均真实变异性 (ARV) 和变异系数 (CV) 描述血压波动性, 通过心脏 彩超评估LVH。分别计算SBP和DBP的VIM、ARV、CV, 并按四分位数划分为四个区间。以第一个四分位区间作为 参考, 借助 3种 Logistic 回归模型, 采用逐步调整混杂因素的方法评估血压波动性与高血压患者 LVH 的关联关系。 结果 2 110 例高血压患者中, 共发现 LVH 600 例。当借助 ARV 评价 SBP 波动性时, ARV 升高会增加高血压患者 LVH的发生概率 (P均<0. 05); 而借助VIM和CV评价SBP波动性时, VIM或CV升高不会增加高血压患者LVH的发 生概率 (P均>0. 05)。当借助VIM、ARV、CV评价DBP波动性时, 三者升高均不会影响高血压患者LVH的发生概率 (P 均>0. 05)。结论　高血压患者住院期间血压波动性与 LVH 的关系仍不确定, 仅借助 ARV 评价 SBP 波动性时, ARV升高会增加高血压患者LVH的发生概率。 [ABSTRACT FROM AUTHOR]
