目的探讨相关知识宣教在无痛肠镜检查患者中的需求现状及应用效果。方法选取行无痛肠镜检查的患者230例，对无痛肠镜检查相关知识的需求情况进行调查；将上述患者随机分为对照组90例和观察组140例，其中对照组给予无痛肠镜检查基础护理，被动回答患者提出的问题；观察组在对照组基础上给予患者及家属主动的、针对无痛肠镜相关知识需求情况系统的、有计划的知识宣教和心理支持。比较2组患者护理前后对知识的掌握情况、检查配合情况以及患者满意度。结果患者及家属对无痛肠镜检查的安全性最为关心，其次是检查前后的注意事项和配合要点，而对麻醉方式的相关知识则相对关注少些。检查前2组患者对无痛肠镜检查相关知识了解程度均较初诊时有明显提高，但观察组患者掌握情况明显优于对照组；观察组患者在检查中配合程度明显优于对照组，检查时间亦明显缩短；观察组患者及家属对护理的满意度明显高于对照组。结论无痛肠镜检查患者对检查的安全性、检查前后注意事项以及配合要点相关知识的需求最为迫切，为患者进行系统的知识宣教对保持检查质量，提高患者的满意度有积极的意义，值得临床推广。

Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

S and Co co-doped carbon catalysts were prepared via pyrolysis of MOF-71 and thiourea mixtures at 800℃at a mass ratio of MOF-71 to thiourea of 1:0.1 to effectively activate peroxymonosulfate(PMS)for methylene blue(MB)*** effects of two different mixing routes were identified on the MB degradation ***,the catalyst obtained by the alcohol solvent evaporation(MOF-AEP)mixing route could degrade 95.60%MB(50 mg/L)within 4 min(degradation rate:K=0.78 min^(-1)),which was faster than that derived from the direct grinding method(MOF-DGP,80.97%,K=0.39 min^(-1)).X-ray photoelectron spectroscopy revealed that the Co-S content of MOF-AEP(43.39at%)was less than that of MOF-DGP(54.73at%),and the proportion of C-S-C in MOF-AEP(13.56at%)was higher than that of MOF-DGP(10.67at%).Density functional theory calculations revealed that the adsorption energy of Co for PMS was -2.94 eV when sulfur was doped as C-S-C on the carbon skeleton,which was higher than that when sulfur was doped next to cobalt in the form of Co-S bond(-2.86 eV).Thus,the C-S-C sites might provide more contributions to activate PMS compared with ***,the degradation parameters,including pH and MOF-AEP dosage,were ***,radical quenching experiments and electron paramagnetic resonance(EPR)measurements revealed that ^(1)O_(2)might be the primary catalytic species,whereas·O~(2-)might be the secondary one in degrading MB.

为了研究沙棘茶水溶性多糖(WPHT)对衰老模型小鼠体内抗氧化能力的影响。本实验通过连续颈部皮下注射D-半乳糖(0.5g/(kg.d))建立小鼠亚急性衰老模型,第11天开始同时灌胃给予沙棘茶水溶性多糖10、50、100mg/(kg.d),40d后检测各实验组血浆超氧化物歧化酶(SOD)活性、丙二醛(MDA)的含量和肝脏匀浆液中SOD活性、过氧化氢酶(CAT)活性和MDA的含量。结果表明,50mg/(kg.d)和100mg/(kg.d)的WPHT可以提高血浆中SOD活性和肝脏匀浆液中的SOD和CAT活性,降低血浆和肝脏匀浆液中的MDA含量,与衰老模型组相比差异显著(P<0.05)。说明WPHT可以提高D-半乳糖致亚急性衰老小鼠的抗氧化能力。
