运动性疲劳中医肾虚证的辨证分型及其诊断标准

目的：阐明运动性疲劳中医肾虚证的主要证候及辨证标准。 方法：于2003-07／2004-01选择湖南省水上运动训练基地的皮划赛艇运动员和省体工大队的田径运动员共199名为研究对象。将中医辨证理论方法与流行病学调研疗法有机结合，统一诊断标准和资料处理方法，分析肾虚各证候构成比，进行聚类分析，观察单一症状出现频次、症状组合出现频次。 结果：纳入受试对象199名，均进入结果分析。①肾虚常见证候有腰脊酸痛，头晕目眩，精神疲倦，四肢乏力，胫膝酸软，气短自汗，五心烦热，口干少津，畏寒肢冷，小便清长，夜尿频多，少寐多梦。②肾虚各证候构成比：肾气虚（51．26％）、肾阴阳两虚（37.69％）、肾阳虚（6.53％）、肾阴虚（4．52％）。③聚类分析：第一类为腰脊酸痛，精神疲倦，四肢乏力，气短自汗；第二类为头晕目眩，胫膝酸软，畏寒肢冷，小便清长，夜尿频多；第三类为五心烦热，口干少津；第四类为少寐多梦。④参与组合频次大于50％的症状主要是：精神疲倦、四肢乏力、腰脊酸痛、头晕目眩、气短，这5个症状也是单个症状频次大于80％的。 结论：运动性疲劳中医肾虚证的常见证候为肾气虚、肾阴阳两虚、肾阳虚、肾阴虚。而肾气虚是运：动性疲劳中医肾虚的主要证候。精神疲倦、四肢乏力、腰脊酸痛、头晕目眩、气短这5个症状可以作为运动性疲劳肾气虚辨证标准中的主要症状。     

诱导型一氧化氮合酶在单侧输尿管梗阻大鼠肾脏的表达

目的:探讨诱导型一氧化氮合酶(iNOS)在单侧输尿管梗阻(UUO)大鼠术侧肾脏的表达.方法:建立左侧输尿管梗阻模型(UUO组),设假手术组为对照.3 d后应用逆转录-聚合酶链反应(RT-PCR)检测iNOS的mRNA水平.结果:与对照组相比,UUO组大鼠肾脏出现明显病理变化,并且其iNOS mRNA表达明显增加.结论:iNOS参与UUO的发生和发展的病理过程.     

Morphology and distribution of neurons and glial cells expressing beta-adrenergic receptors in developing kitten visual cortex.

The morphology and distribution of cells expressing beta-adrenergic receptors has been studied in developing kitten visual cortex using a monoclonal antibody which recognizes both beta-1 and beta-2 adrenergic receptors. We found specific populations of neurons and glial cells which express beta-adrenergic receptor immunoreactivity in the kitten visual cortex. In adult animals, the receptors are most concentrated in the superficial and deep cortical layers (layers I, II, III and VI). About 50% of the stained neural cells in adult cat visual cortex are glial cells. Most of the immunoreactive neurons in layers III and V are pyramidal cells while those in layers II and IV are more likely to be nonpyramidal cells. In neonatal kittens, staining is weaker than that in adult cats and it appears to be concentrated in neurons of the deep cortical layers and in the subcortical plate and white matter. Only a few immunoreactive glial cells were found at this age. Receptor numbers increase after birth and by 24 days of age, the laminar distribution of beta-adrenergic receptors approaches that of adult animals. Immunoreactive glial cells in the white matter show a progressive increase in number throughout postnatal development.     

脉冲Nd：YAG激光照射对大鼠炎症牙龈组织的作用

患实验性牙龈炎的大鼠牙龈（６例）经脉冲掺钕钇铝柘榴石激光（Ｎｄ：ＹＡＧ激光）照射后进行光镜及超微结构观察。目的在于了解低能量Ｎｄ：ＹＡＧ激光照射对牙龈炎症的治疗作用。炎症牙龈经输出能量为１．５Ｗ，脉冲数为２０ＰＰＳ的激光照射后与对照组相比较，形态学上有如下变化：上皮细胞无变性；牙龈上皮层数较炎症时减少；上皮下炎细胞浸润明显减少；上皮细胞间隙变小；上皮下结缔组织内产生大量的排列致密的胶原纤维。结果提     

Toluene vapor exposure and urinary excretion of hippuric acid among workers in China.

A factory survey was conducted in three provinces in China from 1985 to 1989. The time-weighted average toluene concentrations in breathing zone air were monitored by diffusive sampling, whereas hippuric acid (HA) concentrations in shift-end urine samples were measured by high performance liquid chromatography (HPLC). Exposed workers (456 men and women) were those for whom toluene (up to 548 ppm toluene) accounted for greater than or equal to 90% of total exposure (by vapor concentration in ppm), whereas 517 nonexposed controls were recruited from the same factories or from factories of the same region. There was a linear correlation between the intensity of toluene exposure and HA concentration in the shift-end urine. Comparison of the results with findings in the literature shows that the toluene-induced increase in urinary HA concentration among workers in China is significantly smaller than the published values, whereas HA concentrations in urine samples from nonexposed controls are comparable to the levels previously reported.
