摘要：In this study,the enhancement of catalytic activity of ceria when modified with co-catalysts such as graphitic carbon nitride and silver was establishe *** material was synthe sized using phytogenic combustion method,a green alternative to the traditional preparative *** catalyst was characterized using XRD,FTIR,SEM,EDX,XPS and TEM *** synergistic effect of the composite CeO2/g-C3 N4/Ag was tested for catalytic reduction of 4-nitrophenol in the prese nce of sodium *** reaction was carried out at room tempe rature without any light source or exte rnal *** individual and combined effects of four parameters,viz.,concentration of 4-NP,amount of catalyst,amount of NaBH4 and time for the reduction of reduction 4-NP were investigated using Box-Behnken design of response surface methodology(RSM).This statistical model was used to optimize the reaction conditions for maximum reduction of *** optimum conditions for the reduction reaction are found to be 0.01 mmol/L 4-NP,15 mg catalyst,20 mg NaBH4 and 13.7 min time interval.

摘要：目的:探索个体针刺疗法作为常规治疗的辅助手段在精神分裂症患者中的效果;采用探索性病例研究的方法,使用定量和定性评价工具,以便能够对针刺治疗此类患者的确切疗效作出科学评价,并对未来采用针刺治疗此类患者的试验设计提供方法学建议。方法:共纳入11例精神分裂症患者,在予以10周的针刺治疗前,治疗过程中及治疗后分别采用多种有效的定量和定性评价工具对患者进行多方面的评价。这些评价手段包括对针刺治疗、全科医生及精神科医生病历的整理回顾。分析定性资料以评价受试者向研究者及其临床医生和护理人员报告的内容的可靠性。结果:11名受试者中共有8名完成了1个疗程的针刺治疗,全部11名受试者都报告了针刺治疗的积极作用,包括精神分裂症症状的改善,缓解药物的副作用,对精力、内在动机、睡眠、成瘾症状及其他身体机能的促进作用。但是,受试者向研究者和针刺医生报告的信息在不同治疗阶段有一定差别,且往往不一致;在研究结束后,受试者向研究者报告了更多的信息。结论:本研究表明,在常规疗法之外辅以针刺治疗能够给精神分裂症病人带来一定益处。对数据的三角测量表明了受试者报告内容的某些不一致性,而这些可以通过多种研究方法的混合使用得以克服。通过对数据的比较,推荐在将来的研究设计中使用阳性与阴性症状量表、针刺临床试验干预措施报告标准以及在问卷中增加对药物副作用、运动、睡眠以及日常作息的调查。在将来的研究中还应充分考虑到,恢复期患者容易复发,应该让他们可以方便地获得帮助。
