心理干预对维持性血液透析患者影响的随机对照研究

将77例维持性血液透析患者随机分为干预组或对照组。对照组接受常规的血液透析并按医嘱服用重组人促红细胞生成素（rhEPO）;干预组在此基础上,还接受渐进性肌肉放松训练和脑波同步治疗。采用SCL-90量表和SF-36问卷,在干预前、后3天内分别对两组进行测量,同时检测血常规、肾功能及透析间期体重增加量与干体重的比值(IWGR%)。70例患者（干预组36例,对照组34例）完成了实验。结果发现,经过心理干预,干预组的心理健康状况、总体生活质量、血红蛋白（HB）、红细胞计数（RBC）、红细胞压积（HCT）以及透析前血清钙(Ca²⁺)显著高于对照组;透析前血清尿素氮（BUN）、磷 (PO^3-₄)、钾（K⁺）水平以及透析间期体重增加量与干体重的比值（IWGR%）显著低于对照组;两组透析前的血清肌酐（Scr）差异无显著性意义。

Quantum Information Entropies on Hyperbolic Single Potential Wells

In this work, we study the quantum information entropies for two different types of hyperbolic single potential wells. We first study the behaviors of the moving particle subject to two different hyperbolic potential wells through focusing on their wave functions. The shapes of these hyperbolic potentials are similar, but we notice that their momentum entropy densities change along with the width of each potential and the magnitude of position entropy density decreases when the momentum entropy magnitude increases. On the other hand, we illustrate the behaviors of their position and momentum entropy densities. Finally, we show the variation of position and momentum entropies Sx and Sp with the change of the potential well depth u and verify that their sum still satisfies the BBM inequality relation.

应用扩展的UML活动图建模审计专家经验

计算机审计专家经验来源于实践,应用于实践,但目前还没有对专家经验进行建模的统一建模语言.由于模型中的语法语义不一致、不明确,极大妨碍了审计业务人员对专家经验的理解、掌握和应用.统一建模语言(UML)已经成为事实上的信息系统领域建模语言标准.扩展UML活动图将其应用于审计专家经验建模,并给出了具体应用案例.应用扩展的活动图建模专家经验具有简单、清晰、标准化、国际化的优点,并能被不同领域的专家接受和理解.

Investigation Driven by Network Pharmacology on Potential Components and Mechanism of DGS,a Natural Vasoprotective Combination,for the Phytotherapy of Coronary Artery Disease

Phytotherapy offers obvious advantages in the intervention of Coronary Artery Disease (CAD), but it is difficult to clarify the working mechanisms of the medicinal materials it uses. DGS is a natural vasoprotective combination that was screened out in our previous research, yet its potential components and mechanisms are unknown. Therefore, in this study, HPLC-MS and network pharmacology were employed to identify the active components and key signaling pathways of DGS. Transgenic zebrafish and HUVECs cell assays were used to evaluate the effectiveness of DGS. A total of 37 potentially active compounds were identified that interacted with 112 potential targets of CAD. Furthermore, PI3K-Akt, MAPK, relaxin, VEGF, and other signal pathways were determined to be the most promising DGS-mediated pathways. NO kit, ELISA, and Western blot results showed that DGS significantly promoted NO and VEGFA secretion via the upregulation of VEGFR2 expression and the phosphorylation of Akt, Erk1/2, and eNOS to cause angiogenesis and vasodilation. The result of dynamics molecular docking indicated that Salvianolic acid C may be a key active component of DGS in the treatment of CAD. In conclusion, this study has shed light on the network molecular mechanism of DGS for the intervention of CAD using a network pharmacology-driven strategy for the first time to aid in the intervention of CAD.
