肾综合征出血热病毒气溶胶的物理稳定性实验研究

本文采用荧光素钠正常鼠脑悬液做模拟示踪物质，对肾综合征出血热病毒气溶胶在空气中的物理稳定性进行了测定，并与其生物稳定性做了比较。结果表明：病毒气溶胶的粒子大小在１ｕｍ左右，它随气溶胶的胶龄增长而减少，且其分散度变窄。初始气溶胶的物理回收率及其各胶龄的物理存留率均明显地高于它的生物回收率和生物存活率。本文还就肾综合征出血热病毒气溶胶的物理稳定性和生物稳定性，对本病空气传播的影响进行了讨论。     

Effect of linoleic acid, linoleic acid anilide, and arachidonic acid on the expression of adhesion molecules on human neutrophils

The effects of linoleic acid, linoleic acid anilide, and arachidonic acid on the expression of CD11b/CD18, CD11c/CD18 integrins and l-selectin on human neutrophils were studied by flow cytometry in a whole blood assay. None of these compounds had any effect on the basal expression of CD11b, CD11c, or l-selectin in the concentration range of 20–100 μM. However, linoleic acid at a concentration of 1000 μM slightly up-regulated CD11b and CD11c by a factor of 2.1 and 1.7, respectively. Linoleic acid, linoleic acid anilide, and arachidonic acid did not affect the formyl-methionyl-leucyl-phenylalanine induced up-regulation of CD11b or CD11c. However, linoleic acid and linoleic acid anilide slightly inhibited the phorbol myristate acetate (PMA)-induced expression of CD11b, which was decreased by 27 and 21% at concentrations of 100 and 1000 μM, respectively. Likewise, arachidonic acid at 40 μM inhibited the PMA-induced expression of CD11b by 19%. Our results suggest that linoleic acid, linoleic acid anilide, and arachidonic acid do not dramatically affect the expression of leukocyte adhesion molecules in a whole blood assay.

Clinical study of Tuina on tension-type headache with syndrome differentiation

本研究采用六点行为评分法和Stead的诊断表计分法.对治疗组和对照组150例患者进行客观、科学的疗效评定.提示"通脉调气"腹部推拿法在治疗紧张性头痛的疗效上远远高于常规推拿法.同时认为消除由"头痛-肌收缩一头痛"程序而引起过度防御反应是疗效显著提高的理论基础.     

从脾论治磺脲类降糖药继发性失效

对 64例 2型糖尿病继发磺脲类降糖药失效患者 ,在继续口服磺脲类药的基础上加用健脾中药 ,结果显效 1 5例 ,有效 3 6例 ,无效 1 3例 ,总有效率 85 .2 4% ;治疗前后血糖明显下降 ,有显著性差异 ( P<0 .0 0 1 )     

晚期肺癌的中医证候研究

目的　探讨晚期肺癌的主要中医证候。方法　采用回顾性与前瞻性相结合的方法进行临床观察。结果　经 χ2 检验 ,不同中医证候的晚期肺癌组之间有显著性差异 (P <0 0 1) ,而血瘀证、气虚证、痰证、阴虚证最为多见 ;晚期非小细胞肺癌与晚期小细胞肺癌的中医证型没有显著性差异。结论　晚期肺癌的中医证候以血瘀证、气虚证、痰证、阴虚证为主 ;晚期非小细胞肺癌与小细胞肺癌的中医证候无明显差异。     

急性白血病肺部感染病机分析

对54例急性白血病并肺部感染患者临床观察分析发现,急性白血病合并肺部感染的病机与一般肺部感染有本质的不同。本病的发生以气血亏虚严重、精血化生衰竭为主要原因。故应以益气、养阴、补血为治疗大法。对化疗期间病人要注意调理脾胃,顾护胃气,以后天养先天。造血功能抑制的患者,切忌一味攻伐,折伤正气。     

机体阴阳交感现象的熵变分析

借用非平衡热力学理论,分析自然界水火运动的规律,得出结论——阴阳交感过程是熵减少过程,阴阳反作过程是熵增加过程;机体的许多阴阳变化也遵循同一规律。并在此基础上论证了新陈代谢过程是机体从外界输入负熵以抵消体内正熵产生的过程,从而推知阴阳交感现象发生的原因是新陈代谢。     

超声观察银屑病中医分型的血管变化研究

目的　探讨银屑病中医分型皮损处与正常皮肤处血管血流的变化情况。方法　将 3 0例寻常型斑片状银屑病按中医辨证分型 ,超声观察患者正常皮肤处及皮损处浅层动脉血管、静脉血管血流情况。结果　“血热型”皮损处及正常皮肤处动脉血管增大、扩张、血流加快 ;“血瘀型”及“血燥型”未发现异常。结论　银屑病动脉血管及静脉血管增大、扩张、血流加快与中医分型“血热型”密切相关 ,这些将有助于临床根据中医分型进行辨证施治     

Sinoatrial Node Electrogram Studies in Patients with Sick Sinus Syndrome

Sinoatrial node electrogram (SNE) was recorded successfully in recent years, using transvenous electrode catheter. Via SNE and intratrialelectrogram (IEG), one could measure sinoatrial conduction time(SACT) directly, observe sinoatrial node (SN) potential changes in cadiac cycles, diagnose some sinus arrhythmias which couldn't be confirmed by surface ECG. All these could offer accurate evidence for differential diagnosis of sick sinus syndrome (SSS). The authors recommend a modified method for the location of the electrode catheter, by which one can increase success rate of obtaining stable SNE. Using this method, the authors recorded SNE in 10 cases with SSS successfully.
