Abstract: Zeolite HZSM-5 calcined at different temperatures were studied by29Si MAS NMR and EPR method. It was concluded that in certain temperature range, dealumination did not necessarily occur simultaneously with framework dehydroxylation and thus framework Lewis acidic sites emerged. Two processes may be operative with one of them being predominant at different temperatures.

We used the surface-pretreated graphite paper(Gp)as a carrier and loaded BiOCl with high selectivity to Cl^(-)on its surface by solvothermal method to form BiOCl@Gp *** morphology,structure,and composition of the materials were characterized by scanning electron microscopy and nitrogen adsorption/desorption,and the results showed that the spherical BiOCl particles were uniformly dispersed on the surface of the Gp,forming a mesoporous BiOCl@Gp composite with a specific surface area of 22.82 m^(2)/g and a pore volume of 0.043 cm3/***,cyclic voltammetry and electrochemical impedance spectroscopy were used to test the electrochemical properties of the composites,and the stability of BiOCl and the high conductivity of Gp were synergistic,the BiOCl@Gp exhibited a specific capacitance of 30.2 F·g^(-1) at a current density of 0.5 A·g^(-1),and the selectivity of the BiOCl@Gp materials for Cl^(-)was significantly higher than that of SO_(4)^(2-),NO_(2)^(-),and HCO_(3)^(-).Therefore,BiOCl@Gp composite electrode materials can be used for the selective adsorption of Cl^(-)in wastewater,in order to achieve efficient wastewater recycling.

This paper presents a debugging system for multi-pole array acoustic logging （MPAL） tools. The debugging system proposed in this study can debug the MPAL tool system, sub-system and local electronics. In the test equipment, we have used principal and subordinate structures, and interconnected the host computer and the front-end machine via Ethernet. The front-end machine is based on the ARM7 （advanced reduced instruction set computing （RISC） machine） technique, the processor of which runs an embedded operating system, namely, uClinux OS. We have analyzed the system telecommunication, human-machine interface circuit, transmitter mandrel interface circuit, receiver mandrel interface circuit, and board-level test interface circuit. The software used in the system consists of the embedded front-computer software and the host application software. We have explained in detail the flow chart of the boot loader in the embedded front-computer software. The host application software is composed of four application subroutines, which match with the functional modules of the system hardware. A net communication program based on the server^client mode is implemented by means of socket programming and multi-thread programming. Test results indicate that the data transmission rate of the system is higher than 1 MB/s, which completely meets the current requirements of the data transmission rate between the tool system and the wireline telemetry device. Application of the debugging system, which includes multiple level test methods, shows that the proposed system can fully meet the test requirements of MPAL at various levels.

长期服用免疫抑制剂导致的免疫功能低下状态、反复住院及广谱抗生素的使用、移植相关糖尿病的存在、遗体捐献的增加等因素导致实体器官移植(solid organ transplantation,SOT)受者侵袭性真菌病(invasive fungal disease,IFD)的发生风险日益增加,且近年来SOT受者IFD的流行病学也在不断改变。了解SOT受者IFD的流行病学现状、熟悉IFD的新型诊断技术、掌握新型抗真菌药物特性,有助于进一步改善受者预后。本文针对SOT受者IFD的发病率、致病菌构成、新型诊断技术及近年上市的全新抗真菌药物等方面进行简要阐述,以期为临床提供参考。

A quinoline-based colorimetric chemosensor （QDB） for Cu2＋ was synthesized by coupling quinoline-2- carbaldehyde with 4-（dimethylamino）benzohydrazide. Although most transition metal cations can cause redshiffs in the UV-vis spectrum of QDB, the response of the chemosensor for Cu2＋ can be easily distinguished because it exhibits the largest redshift together with a color change from colorless to red in response to Cu2＋. Other metal ions have no effect on the specific response of QDB to Cu2＋. The significant redshift and color change were attributed to Cu2＋-induced deprotonation of NH in the sensor.

目的基于分子药理学方法研究一种中药灌肠制剂对小鼠溃疡性结肠炎的保护及辅助治疗作用。方法构建葡聚糖硫酸钠盐诱导的溃疡性结肠炎小鼠模型,随机分为正常对照组、模型对照组、美沙拉嗪组、美沙拉嗪+灌肠液组,除正常对照组外,其余各组小鼠每天自由饮用4%葡聚糖硫酸钠盐溶液7 d。美沙拉嗪+灌肠液组每天灌胃给予0.52 g·kg^(-1)美沙拉嗪,且每天早晚用自制中药制剂灌肠;美沙拉嗪组每天灌胃给予0.52 g·kg^(-1)美沙拉嗪,且每天早晚用0.9%氯化钠溶液灌肠;正常对照组和模型对照组每天用0.9%氯化钠溶液灌胃,且每天早晚用0.9%氯化钠溶液灌肠,连续14 d后,取结肠组织冷冻备用。结果溃疡性结肠炎可使小鼠体质量显著下降,美沙拉嗪可以帮助小鼠减少体质量下降趋势,美沙拉嗪+灌肠液组效果优于美沙拉嗪组。苏木精-伊红染色法染色及组织学评分结果显示,美沙拉嗪能有效降低小鼠结肠组织的组织学评分,合用灌肠液可以加强这一作用;采用酶联免疫吸附测定方法检测小鼠结肠组织中肿瘤坏死因子-α、干扰素-γ以及白细胞介素-6的含量,灌肠液能增强美沙拉嗪对炎性因子的下调作用;采用蛋白质免疫印迹试验法检测小鼠结肠组织中凋亡基因cleaved caspase-3,Bax,Bcl-2的表达情况,灌肠液可增强美沙拉嗪对cleaved caspase-3、Bax蛋白的上调作用和对Bcl-2蛋白的下调作用。结论联合应用中药灌肠液能增强美沙拉嗪对小鼠溃疡性结肠炎的治疗作用、对炎性因子和细胞凋亡的抑制作用,为临床联合应用提供理论依据。
