Topical imiquimod treatment of cutaneous vascular disorders in pediatric patients: clinical evaluation on the efficacy and safety

Objective:To evaluate the clinical effect of topical imiquimod treatment on cutaneous vascular disorders in pediatric patients.Methods:A retrospective investigation was conducted in 25 pediatric patients with cutaneous vascular disorders,including 19 infantile hemangiomas(IHs)(12 superficial/7 mixed type),5 nevus flammeus(NF),and 1 pyogenic granuloma(PG).Imiquimod 5% cream was applied every other day for 4 to 16 weeks(average 9.6 weeks).Results:Of the 19 IHs treated,an overall efficacy of 52.6% was achieved,with a clinical resolution rate of 15.8%,excellent rate of 26.3%,and moderate rate of 10.5%.The superficial type responded the best at 66.7%,while the mixed type showed only 28.6% effectiveness,which was predominantly from their superficial parts.No obvious response was noted in the 5 patients with NF.Side effects were observed in 78.9% of the patients,mostly mild to moderate local irritations and occasionally severe reactions such as thick crusting and ulceration.Systemic side events were observed in 4 IH patients including fever and digestive tract reactions.No recurrence was observed during the follow-up examination.Conclusions:Topical imiquimod could be an alternative option for the treatment of uncomplicated superficial IHs with satisfactory tolerability.     

Study on shift schedule saving energy of automatic transmission of ground vehicles

To improve ground vehicle efficiency,shift schedule energy saving was proposed for the ground vehicle automatic transmission by studying the function of the torque converter and transmission in the vehicular drivetrain.The shift schedule can keep the torque converter working in the high efficiency range under all the working conditions except in the low efficiency range on the left when the transmission worked at the lowest shift,and in the low efficiency range on the right when the transmission worked at the highest shift.The shift quality key factors were analysed.The automatic transmission's bench-test adopting this shift schedule was made on the automatic transmission's test-bed.The experimental results showed that the shift schedule was correct and that the shift quality was controllable.

听力正常耳鸣患者治疗前后诱发性耳声发射的临床研究

目的:分析耳鸣与耳蜗毛细胞早期损害的关系,以及听力正常耳鸣患者治疗后基本痊愈和显效的病耳耳蜗毛细胞恢复情况。方法:40例(66耳)纯音听力正常的耳鸣患者,行诱发性耳声发射检查:瞬态耳声发射(TEOAE)和畸变产物耳声发射(DPOAE)检查,并对耳鸣患者给予相应治疗,对基本痊愈和显效的病耳治疗前DPOAE或TEOAE未通过的复查DPOAE或TEOAE。结果:①治疗前TEOAE检查28耳通过,38耳未通过;DPOAE检查34耳通过,32耳未通过;②经治疗,38耳治疗前TEOAE检查未通过的患耳基本痊愈和显效的病耳有15耳,复查TEOAE,3耳通过;32耳DPOAE检查未通过的患耳基本痊愈和显效的病耳有13耳,复查DPOAE,4耳通过。结论:部分听力正常的耳鸣患者已有耳蜗毛细胞的损害,而且不易恢复。     

现代护理视野下的《医护礼仪与形体训练》模块教学探讨

传统教学方法对教师和学生造成束缚,而模块式教学体现了以人为本的教学思想。在高职护理专业《医护礼仪与形体训练》中采用模块式教学,尤其在训练模块教学,注重了教学方法的改革;注重了对学生综合能力的培养,做到了学以致用,为学习者提供了思维的空间和实践的新天地,调动了他们学习的积极性、主动性,为今后上岗就业打下了良好的基础。

晚期子宫内膜癌治疗方法与预后分析

目的:探讨晚期子宫内膜癌临床特征及预后相关因素.方法:回顾性分析我院1995.1～2005.1月间收治的39例晚期子宫内膜癌患者临床病理资料和随访结果.结果:①39例患者中,Ⅲ期25例(64.1%),Ⅳb期14例(35.9%);手术治疗35例,单纯放疗3例,单独孕激素治疗1例;5年生存率21.8%.结论:子宫浆膜受侵、子宫外多处癌灶、宫旁组织受侵犯、宫旁淋巴管或血管有癌栓及淋巴结癌转移仍是影响晚期子宫内膜癌预后的重要因素,Ⅳ期患者易盆腹腔复发和肺转移,预后更差.     

影视欣赏与跨文化交际教学

大部分人对于跨文化交际教学中的电影教学存在一个共同误区,认为电影是一个传授手段,利用影片教学就是放放电影,其效果十分有限。而实际上,如果我们把影片视为一个实践手段,一个自我评估手段,影片教学这个方法的效果也许不是那么有限。在教学进行到一定程度的时候播放了《刮痧》这部影片,学生运用所学知识对此进行跨文化差异分析,把影片教学当作一个实践手段和评估手段,不仅解答了学生对与该课程实际意义的困惑,而且进一步激发了学生学习跨文化交际学的兴趣。

Impacts of consolidation procedures on colour and absorption kinetics of carbonate stones

The aim of this research work was to test the influence of stone properties, consolidation product, and application procedure on the potential harmfulness of consolidation on carbonate stones as assessed through the impacts on colour and water absorption kinetics. This article contributes to understanding the immediate and delayed impacts of consolidation treatments through the assessment of colour variation and modification of water absorption kinetics. The investigation was carried out on two limestones having a porosity of 10 and 27%, which were treated with three consolidating products (ethyl silicate, acrylic, and epoxy resins) using three treatment procedures: capillary absorption, brush, and full immersion. All products showed negative impacts at different degrees. We could show that their impact on a given stone depends not only on the consolidant type, but also on the treatment procedures. We demonstrated this way that the assessment of the potential harmfulness of a consolidation treatment for a specific intervention should be carried out in conditions as similar as possible to those expected to occur in practice and should never be based on extrapolations made from any other different conditions. The results also contribute to the definition of standard testing protocols in stone consolidation, privileging the application of a consolidant by direct contact capillary absorption when reproducibility is pursued, or by brushing when the potential highest impacts on colour are the target to evaluate.
