中药蒸汽眼罩的制作与应用

现代生活节奏加快,人们用眼过度,导致许多人患出现眼部疲劳、易流泪、黑眼圈等眼部不适,为解决这一问题,经过研究与分析,笔者研制出了一款"中药蒸汽眼罩"。本款蒸汽眼罩选用了菊花、金银花、决明子、丹参、远志、忍冬藤、夜交藤、菟丝子,八种明目安神且无不良反应的中草药,通过蒸汽,可以将有效成分传导至眼部肌肤。本团队将"中药蒸汽眼罩"投入使用,使用者对于"中药蒸汽眼罩"最满意的前五点分别是:包装拆开方便性、发热温度、发热时长、眼罩材质、贴肤性,94%的使用者会考虑长期使用"中药蒸汽眼罩"来缓解眼部不适。本产品具有创新性,将中草药与蒸汽眼罩有机结合,可以有效缓解以上症状。     

久罚不倒的高通何以神通广大?

2月10日,芯片巨头高通公司方宣布接受中国国家发改委9.75亿美元的罚款,并将对中国市场的智能手机专利授权作出多项调整,包括专利费调整、取消专利反授权。在国际IT市场监管游戏中,高通算是“老油条”了,被处罚也不是第一次。此次在中国市场遭遇天价罚单之前,高通在其他经济体曾遭遇过多次反垄断调查。2005年,博通在美国起诉高通违反反垄断法和专利侵权,高通最终扔下8.91     

电子报尿器的制作与应用

婴儿排尿次数较多,婴儿排尿后,如不及时更换尿布,容易诱发婴儿湿疹,且使婴儿睡眠不好,影响其身体健康.为此,我们根据低频振荡电路工作原理,制作了电子报尿器,当尿布湿后,可立即发出声响,从而提醒父母或护理人员及时更换尿布.现将其制作及应用介绍如下.     

应用组织芯片技术研究光暴露皮肤与非光暴露皮肤中PCNA的表达

目的:比较光暴露与非光暴露皮肤中增殖细胞抗原的表达。方法:组织芯片按文献报道方法制备,用免疫组化链霉素亲和素-生物素法(Streptavidin-Peroxidase SP法)检测,一抗为1:100鼠抗人单克隆抗体。结果:36例光暴露皮肤组织中14例(38.9%)阳性;19例非光老化皮肤中18例(94.7%)阳性(χ2=4.2,P<0.01)。结论:光暴露部位皮肤组织PCNA蛋白表达较非光暴露部位皮肤组织表达明显减少。日光对细胞增殖因子的表达起抑制作用。推测日光对皮肤组织的增生能力有阻滞作用,加速皮肤老化。     

基牙损伤后保留烤瓷冠制作桩钉体会

烤瓷冠制作完成后,病人佩戴使用过程中经常会发生基牙受损出现龋坏或基牙劈裂折断,以往都需重新制作桩钉后再重新做烤瓷冠,这样既浪费工时又给病人带来巨大的经济损失.近几年来,我们采用保留原烤瓷冠倒作桩钉的方法进行修复,取得了较满意的临床效果.现将基牙受损后保留烤瓷冠制作桩钉操作步骤与方法及制作要领分述如下:     

多媒体课件的制作及其在临床麻醉教学中的应用

如何结合本专业特点和学生实际情况，设计和制备适合本专业特点的多媒体课件，就成为每个担任教学任务的教师提高教学质量，高效率利用多媒体技术开展教学的重要任务。经过几年的探索与实践，我们制作的全身麻醉气管插管术多媒体课件，在教学过程中不断总结、更新、充实，取得了良好效果。     

制作细粒棘球绦虫原头蚴染色标本方法的初探

目的 探索制作结构清晰、颜色鲜明、能长期保存的细粒棘球绦虫原头蚴标本的方法。方法 孔雀绿染色法：将原头蚴分别用1％、2％和4％孔雀绿水溶液，在室温或36℃染色24h、48h和72h。结果 4％孔雀绿水溶液，36℃，染色48h为最佳条件。染色后原头蚴头钩呈亮绿色，而吸盘和实质部分无色透明，标本的对比性和立体感强。结论 用孔雀绿染色法制作原头蚴标本在临床诊断和教学中有实用价值。     

马鞍型糜芯围领的制作与应用

颈椎前后路开窗减压植骨融合术是手术治疗颈椎骨折合并脱位、颈椎骨折合并脊髓损伤、颈椎间盘突出等病症最为常用和有效的手术方法之一。为了提高手术疗效，增加患者的舒适感，我们于1999年自行设计制作了马鞍型糜芯围领，经过6年临床应用效果良好，未发生植骨块滑脱或移位，枕部、下颌部、耳部及肩胛部血肿及压疮的发生率也由使用颈托时的46．36％降至0，现报道如下。     

表达谱基因芯片筛选体外循环前后心肌细胞因子的变化

Objestive Systemic inflarmmation may be triggered by injury, hypothermia, ischemia-reperfusion and the contact of the blood with foreign body during cardiopulmonary bypass (CPB). To determine the application values of gene chip technique in the clinical practice and the study of cardiovascular stagery, as well as to provide clues to the study of inflammatory responess during CPB, microarry for gene expression profiles was used to identify the differences in the gene expression of myocardium between pre-and post- CPB. Methods Six adult patients who underwent CPB from March to May in 2003 were involved. Samples of right atrium were col- lected before and at immediate end of CPB. BD AtlasTM cDNA Expression Arrays was used to identify the differences in the gene ex- pression of cytokines. The results were compared with that of semi-quantative RT-PCR. Resellts The mean age of 6 patients (5 males and 1 female) was (32.67± 11.72) years. The baseline heart function was gradeⅡin 3 cases and grade Ⅲ in 3 other cases. The baseline left ventricular ejection fraction(LVEF)was (58.17±7.91)%. The mere duration was (91.67±43.88) minutes for CPB and was (58.67±43.46) minutes for aorta blocking. The minimum nasopharynx/rectal temperture was (29.37±1.90)℃/ (32.15±1.52)℃. Gene expression profiles of cytokines in the myocardium pre- and post-CPB were analysed successfully. The ex- pression of IL-6, IFN-γ,Wnt5a, TNFRSF1B, a member of tumor necrosis factor receptor superfamily, PIGF and MFNG in the myo- cardium were unpregulated after CPB. Conclusion Microarray technique is applicable in the study of cytokines changes dying CPB. cDNA microarray identified pleliminarily the differences in the gene expression between pre- and post-CPB. These genes may be in- valved in inflammation and other psthophysiological responses incuced by CPB. The myocardiym is probably one of the major sources of cytokines during CPB. Further study may be helpful in understanding the llngthe development of inflammation during CPB, and eventually, reducing the post-operative complications.
