不同部位鼻中隔偏曲的鼻内镜手术矫正

近年来随着鼻内镜手术的不断普及,鼻内镜技术被广泛应用于鼻中隔手术。鼻中隔矫正手术的目的、适应证以及手术方法较过去有了明显不同。传统的鼻中隔黏膜下矫正术由于视野狭小,能见度差,术野暴露不充分,在对高位、后段和不规则的复杂鼻中隔偏曲患者施行手术时,常易出现矫正不彻     

代孕技术中的伦理道德及法律问题

新近发展的代孕技术给众多不孕夫妇带来为人父母的喜悦之时,也对人们传统的生殖伦理观念形成冲击并挑战现存法律制度.人们不仅要肯定代孕技术的合理性,也要警惕其所产生的潜在的破坏性影响.合理利用该技术和制定相应的法规是避免出现伦理和社会混乱的有效途径.

《护理学基础》教学中应用多媒体技术的利弊

随着计算机和网络技术日新月异的发展，计算机的普及应用，计算机辅助教学特别是多媒体课件的应用在护理教育中越来越受重视。然而我们在《护理学基础》教学中推广使用时发现：多媒体教学存在弊端，其效果不尽人意，不如教学者期望的那样高。因此，有必要对多媒体技术应用在《护理学基础》教学中的利弊进行探讨，报道如下：     

重复使用固相放免双抗体快速检测HBVm

固相放射免疫分析方法无需加分离剂，是一种操作简便，快速的新型放射免疫分析方法。但由于原材料缺乏，试剂的来源不足，致使这项实验免疫技术在常规应用中受到一定限制。本文参考ch’ng SL（Lancet1986）等的报告，对固相放免两步夹心法检测待检血清中病毒性乙型肝炎抗原抗体系统血清各标志物（HBVm）阴性的聚苯乙烯固相抗体和^125I-标记抗体重复使用，采用一步夹心法技术进行观察，结果令人满意，现报告如下。     

护患间如何交流

护患交流是特殊环境下人与人之间的交流，交流能否达到预期的目的和效果，关键在于护理工作者如何为自己和患者确定一个适当的角色，工作中有以下认识和体会。     

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.

左室舒张功能不全57例临床分析

近年来，由于细胞分子生物学、心导管、超声多普勒技术等方面的进展，对充血型心力衰竭（CHF）的认识有了较和更新大的改进，已将左心功能不全区分为收缩功能不全和舒张功能不全，虽然两者在临床上均表现为体循环和肺循环淤血，但两者引起心衰病理生理学变化特点却截然不同，所以两者的治疗有着更本的区别，其中舒张性功能不全是一种相对常见、预后不良的临床综合征。有大约1／3的慢性心力衰竭病人属于这种类型。现将我院57例患者分析如下。     

直径≤5cm的卵巢包块304例临床分析

近年来妇科门诊发现的直径≤5cm的卵巢包块病例数明显上升，其中包括卵巢肿瘤和卵巢瘤样病变。以往认为对诊断不明的直径≤5cm的卵巢包块可以短期观察，但随着医疗技术的进步，特别是腹腔镜的广泛应用，早期明确诊断及治疗已成为可能。我们对直径≤5cm的卵巢包块患者的临床资料进行了回顾性分析，现报道如下。
