Comparison of histopathological characteristics of allograft biopsy between responder and non-responder to antiproteinuric effect of angiotensin-converting enzyme inhibitor (ACEI)

Abstract:  Angiotensin-converting enzyme inhibitor (ACEI) has become recognized as agents that have renoprotective effects in the treatment of progressive renal diseases including post-transplant kidneys. Previously we demonstrated the safety and effectiveness of ACEI treatment on the hypertensive proteinuric post-transplant patients ( N  = 10) who had been followed up for 12 months. However, not all patients show good response in urinary protein reduction. We aimed to analyse the histopathological factor(s) affecting the responsiveness of proteinuria to ACEI treatment. Fourteen post-transplant patients with proteinuria who were treated with ACEI and underwent allograft biopsy were analysed. Eight patients showed 50% or more reduction in proteinuria (responder). The other 6 patients showed less (< 50%) reduction in proteinuria (non-responder). There was no difference in clinical characteristics (BP, renal function, donor age, recipient body mass index), dietary sodium or protein intake, and diuretic use between the two groups. As a histopathological characteristic, glomerular size in responder group was significantly larger than that in non-responder group. This suggests that the large glomerular size at least partly contributes to the responsiveness in urinary protein reduction to ACEI treatment in kidney allograft recipients with proteinuria.     

肺结核病人健康教育现状调查与影响因素分析

目的　调查活动性肺结核病人在诊断前接受结核病知识的教育现状 ,分析病人接受结核病知识与社会经济因素的影响。方法　对 2 0 0 0年全国结核病流行病学抽样调查中的 1 2 78名活动性肺结核病人进行社会经济个案调查 ,调查以问卷的形式进行。结果　 1 2 78例肺结核病人在诊断前有 5 1 4例接受过不同形式的健康教育 ,占 40 2 % ,男性接受健康教育比例为 41 8% ,女性为 3 6 9%。各年龄组接受健康教育比例 <1 5岁组最低为2 5 9% ,其次是 65～年龄组为 3 0 9%。随着病人文化程度的增高和家庭人均年收入的增高 ,接受健康教育比例增高。肺结核病人各种职业的分类中 ,无工作者接受健康教育比例最低为 3 5 5 % ,其次为农林牧渔劳动者。按照病人是否有症状、有症状后是否就诊及最后诊断为肺结核病人的 3个过程接受不同形式的健康教育的频率 ,均以广播电视、健康教育和亲友教育为主。结论　在开展健康教育活动中 ,应注意对儿童和老年人群 ,对于文化程度低、家庭经济收入低、无工作者和农林牧渔劳动者等重点人群的教育     

Agilent 2100 Bioanalyzer在人乳头瘤病毒检测中的应用

目的：探讨Agilent2100Bioanalyzer芯片分析系统（简称Bioanalyzer)在人乳头瘤病毒（HPV）的PCR检测和分组中的应用。方法：先分别进行通用引物介导PCR（GP－PCR）和型特异性引物介导PCR，扩增HPV高保守区（L1区）的共同序列和各型（包括HPV6，11，16和18型）的特型性序列，然后分别用常规的琼脂糖凝胶电泳技术和Bioanalyzer对PCR产物进行检测，并比较两种检测方法的准确度，重复性和灵敏度。结果：Bioanalyzer在确定片段长度时的准确度和重复性比琼脂糖凝胶电泳高，前者的准确度在95％以上，后者仅为85％，Bioanalyzer的检测灵敏度比琼脂糖凝胶电泳高100倍，结论：Bioanalyzer芯片分析系统结合PCR方法可对HPV进行特异，准确，稳定，灵敏的检测和型别鉴定，具有重要的推广价值。     

The dental management of patients with bipolar disorder

Bipolar disorder (manic depressive disease) affects 1% of the United States population. These persons suffer from prolonged episodes of extreme elation and depression. There is a significant incidence of dental pathosis and a need for dental care among these patients. The medications used for the treatment of this disease, their physiologic effects, and their interactions with the drugs used in dentistry are reviewed.     

急性软脑膜微循环障碍实验模型的研究

本文报道应用高分子右旋糖酐制成软脑膜微循环障碍的动物实验模型。软脑膜微循环障碍模型的标志;软脑膜微血管血流速度减慢,血液流态呈粒状流或絮状流,血细胞聚集。 将98只家兔分成甲、乙二组。甲组38只,静脉注射平均分子量为25万的高分子右旋糖酐,乙组60只,静脉注射平均分子量为49万的高分子右旋糖酐。实验结果发现,甲组38只家兔仅28只可复制成软脑膜微循环障碍的实验模型,模型复制成功率为73.6％;乙组60只家兔,59只可形成软脑膜微循环障碍实验模型,成功率为98.3％。本实验证明复制动物模型以49万分子量的高分子有旋糖酐为宜。 本实验模型可用于脑微循环障碍和改善脑微循环药物的研究工作。
