目的分析丙泊酚-瑞芬太尼静脉维持麻醉与静吸复合维持麻醉在颅脑肿瘤手术中的应用效果。方法回顾性分析选择郑州市中心医院2020年3月至2021年6月期间收治的126例颅脑肿瘤手术患者作为研究对象,根据麻醉方案不同将患者分为对照组与观察组,每组各63例。对照组给予丙泊酚+瑞芬太尼静脉维持麻醉;观察组则采用静吸复合维持麻醉。比较麻醉效果和患者手术状况,即各时刻血流动力学指标、拔管时间、术中苏醒时间、不良反应、视觉模拟评分(VAS)等。结果比较T0、T1、T2、T3、T4、T5时间点,组间患者平均动脉压(MAP)、心率(HR)、脑电双频指数(BIS)指标,差异无统计学意义(P>0.05),观察组苏醒时间、拔管时间低于对照组(P0.05);观察组VAS评分低于对照组,睡眠评分高于对照组(P0.05)。结论颅脑肿瘤手术患者接受静吸复合维持麻醉,其效果比丙泊酚+瑞芬太尼静脉维持麻醉效果更理想,且对患者术后恢复无较大影响,可确保麻醉安全性。

In this paper, we study how adaptive coupling with time-periodic growth speed (TPGS) affects the spiking synchronization of weighted adaptive Newman-Watts Hodgkin-Huxley neuron networks with time delays. It is found that the neuronal spiking intermittently exhibits synchronization transitions between desynchronization and in-phase synchronization or anti-phase synchronization as TPGS amplitude or frequency is varied, showing multiple synchronization transitions. These transitions depend on the values of time delay and can occur only when time delay is close to those values that can induce synchronization transitions when the growth speed is fixed. These results show that the adaptive coupling with TPGS has great influence on the spiking synchronization of the neuronal networks and thus plays a crucial role in the information processing and transmission in neural systems.

A huge amount of waste printed circuit boards(WPCBs) was produced while the electronic manufacturing industry developed rapidly. WPCBs mainly consist of organic compounds, which makes it possible to prepare them into porous carbon as valuable adsorbent. However, WPCBs are also rich in valuable *** makes up the most of these metals. It is worth studying whether the residual metal will affect the application of carbon materials. In this study, the porous active carbon(AC) was prepared from WPCBs as an adsorbent. Sulfadiazine(SD), a widely detected antibiotic contaminant, was used as a target *** acid(HNO_(3)) was used to modify AC(AC-HNO_(3)) to remove the residual Cu. The experiment results showed that the adsorption kinetics of SD by AC(k = 0.0025) and AC-HNO_(3)(k = 0.0029) can be described better using a pseudo-second-order kinetic equation. The adsorption isotherms of AC and AC-HNO_(3) on SD could be fitted by the Langmuir model. AC had a larger adsorption capacity than AC-HNO_(3). Density functional theory(DFT) calculation results suggested that the-OH group and Cu on the surface of AC could be the adsorption sites and promote the SD adsorption. This work provides practical methods to recycle WPCBs into wealth and realized waste control by waste.

Developing selectively targeted photothermal agents to reduce side effects in photothermal therapy remains a great challenge. Inspired by the key role of endoplasmic reticulum in the protein synthesis and intracellular signal transduction, particularly for the immunogenic cell death induced by endoplasmic reticulum stress, we developed an endoplasmic reticulum-targeted organic photothermal agent(Ts-PTRGD) for enhancing photothermal therapy of tumor. The photothermal agent was covalently attached with 4-methylbenzenesulfonamide and cyclic Arg-Gly-Asp(c RGD) peptide for realizing the targeting of endoplasmic reticulum and tumor cell. Owing to its amphiphilic properties, it readily self-assembles in water to form nanoparticles. The photothermal agent possesses excellent photophysical properties and biological compatibility. In vitro and in vivo experiments demonstrate that it can actively target endoplasmic reticulum and effectively ablate tumor with near-infrared laser.

Polarization and conductance losses are the fundamental dielectric attenuation mechanisms for graphene-based absorbers, but it is not fully understood in revealing the loss mechanism of affect graphene itself. For the first time, the reduced graphene oxide(RGO) based absorbers are developed with regulatory absorption properties and the absorption mechanism of RGO is mainly originated from the carrier injection behavior of trace metal Fe nanosheets on graphene. Accordingly, the minimum reflection loss(RLmin) of Fe/RGO-2composite reaches-53.38 dB(2.45 mm), and the effective absorption bandwidth achieves 7.52 GHz(2.62 mm) with lower filling loading of 2 wt%. Using off-axis electron hologram testing combined with simulation calculation and carrier transport property experiments, we demonstrate here the carrier injection behavior from Fe to graphene at the interface and the induced charge accumulation and rearrangement, resulting in the increased interfacial and dipole polarization and the conductance loss. This work has confirmed that regulating the dielectric property of graphene itself by adding trace metals can not only ensure good impedance matching, but also fully exploit the dielectric loss ability of graphene at low filler content,which opens up an efficient way for designing lightweight absorbers and may be extended to other types materials.
