通心络胶囊对冠心病治疗效果的临床对照观察

目的观察通心络胶囊对冠心病（CHD）常见临床症状的改善效果。方法对照组维持原有药物治疗不变,治疗组在此基础上加服通心络胶囊4粒/次,3次/日,疗程4周。病人接受观察前进行常规化验检查,检测心率、血压、心功能等指标。疗程结束时对上述指标再进行检查,并观察病人的临床症状改善情况。结果两组病人的胸痛、胸闷、气憋、心悸、乏力等常见临床症状均有改善,且治疗组明显优于对照组（P〈0.05）;治疗组每搏量和心排血量的较对照组提高较为明显（P〈0.01）。结论加服通心络胶囊治疗CHD能增强西药的治疗效果,进一步改善CHD病人的常见临床症状。     

NMDA受体介导了加兰他敏对阿尔茨海默病大鼠认知功能的改善

目的研究加兰他敏对阿尔茨海默病(AD)大鼠认知功能的影响及NMDA受体在其中的作用。方法雄性SD大鼠65只,随机分为假手术、链脲菌素(STZ)组,加兰他敏、MK-801和犬尿烯酸3个治疗组。侧脑室注射STZ制备大鼠AD模型,水迷宫试验测定大鼠的学习记忆能力。3个治疗组分别给予加兰他敏、MK-801 加兰他敏、犬尿烯酸 加兰他敏,共6周。结果术后第10天各组潜伏期明显延长,过平台次数明显减少,差异均无统计学意义。治疗6周后加兰他敏组潜伏期缩短,过平台次数增加,与STZ组比较,有显著差异,而MK-801和犬尿烯酸组潜伏期和过平台次数与STZ组比较,无明显差异。结论加兰他敏对AD大鼠的认知功能具有明显的改善作用,而应用NMDA受体阻断剂后其治疗作用消失。说明NMDA受体介导了加兰他敏对AD大鼠认知功能的改善。     

Improved bioavailability and clinical response in patients with chronic liver disease following the administration of a spironolactone: β-cyclodextrin complex

Aims To compare the absorption and clinical effect of spironolactone from an inclusion complex with β-cyclodextrin (SP-COMP) to Aldactone tablets (ALD) in chronic liver disease.
Methods Patients, admitted with chronic liver disease, completed a randomized crossover steady state study. They received their spironolactone dose as either daily SP-COMP or ALD for 7 days. Serial blood samples were drawn over a 24  h period from day 7 of each therapy. Accurate fluid balance was recorded on days 5–7 and 12–14. Thirteen (six females) whose mean (s.d.) age and weight was 58.4(9.3) years and 74.3(19.0)  kg completed the study.
Results The mean (95% confidence limits) relative bioavailability for SP-COMP (compared with ALD) from steady state serum concentrations of canrenone, 6β-hydroxyl 7α-thiomethyl spironolactone and 7α-thiomethyl spironolactone was 310.0 (265.4, 336.7), 233.4(212.9, 250.8) and 254.8(230.8, 279.0)%, respectively. Improvements in clinical status and fluid balance occurred over the last 3 days of SP-COMP with a mean (s.d.) net loss, in fluid balance, of 1370(860)ml compared with a gain of 228(936)ml during ALD.
Conclusions Better absorption of spironolactone from the spironolactone: β-cyclodextrin complex formulation should lead to a reduction in dosage and perhaps a more consistent effect in patients with chronic liver disease.     

社会支持对考试应激的影响

目的了解社会支持对考试应激的影响。方法采用焦虑自评量表和社会支持量表分别对７２７个学生考试前１个月、考试期间考试焦虑分数及社会支持情况进行调查，比较分析考试焦虑分数与社会支持因素的关系。结果考试焦虑分数与客观支持、来自同学和老师的主观支持以及社会支持的利用度成反比。结论家长和学校给予学生足够的社会支持，以及让学生参加适当的社会活动，培养他们利用社会支持的能力，有助于让学生减缓考试应激的水平

西宁地区冠心病113例临床分析

本文通过西宁地区１１３例住院冠心病人的临床分析，认为西宁地区冠心病患病率低，患者年龄大，男性患病率高于女性，而且绝经期后的高龄女性患者患病率仍然远比男性低，这些与低海拔地区不同。而冠心病各型的分布、临床症状、病死率等与低海拔地区相似。     

Intrauterine position affects motoneuron number and muscle size in a sexually dimorphic neuromuscular system

The intrauterine position occupied by a rodent fetus influences the amount of testosterone to which it is exposed before birth. Animals that are gestated between two male fetuses (2M) are exposed to higher circulating levels of testosterone than are animals positioned between two female fetuses (2F) and there are reliable differences in the reproductive physiology and behavior of 2M and 2F animals when adult. To determine whether intrauterine position modifies development of the central nervous system, we examined the sexually dimorphic spinal nucleus of the bulbocavernosus (SNB) in male and female gerbils from known intrauterine positions. We found that adult 2M female gerbils had 16% more SNB motoneurons than did 2F females. 2M males did not differ from 2F males in SNB motoneuron number, but the bulbocavernosus muscle, which is innervated by SNB motoneurons, was approximately 50% larger in 2M than in 2F males. These data indicate that intrauterine position can influence the morphology of the sexually dimorphic SNB neuromuscular system.
