中国近代西医产科学史

本文阐述了中国西医产科学的发展历史。由于传统封建思想的阻碍,我国现代产科学的起步较晚,１９１１年在福建省建立了我国第一所产科病房。１９３０年以前孕产妇及新生儿死亡率比英美高４～５倍,１９３０年后,建立助产学校,开展孕期保健及骨盆测量,不断改进对病理妊娠的诊断及妊娠合并症的处理,这些均促进了中国近代西医产科学的进步,也为建国后的发展奠定了基础。     

谷子种子经高空气球搭载后的遗传变异研究

目的 选育出高产、蛋白质和用脂肪含量高的谷子品（系）种。方法 利用高空气球搭载谷子的干种子,在高空飘游８ｈ后回收种植,对其植物学特性及进行分析研究。结果 种子发芽率比对照低５．２％,发芽热比对照高２１．１％。ＳＰ１代植株高度比对照低６．８ｃｍ,旗叶面积比对照高２５％,穗重比对照高１５．９％;ＳＰ３代大穗型株系性状相对稳定,其中ＳＰ３－２的种子蛋白质和脂肪含量均高于对照经高空气球搭载后的ＳＰＥ－３５     

持续性正加速度致意识丧失的机理及其监测

正在加速度引起的意识丧失（Ｇ－ＬＯＣ）是当胶威胁飞行安全的主要因素。综述了Ｇ＿ＬＯＣ的机理及其生理监测,慢增长率正加速度导致的意识丧失的机理主要大脑缺血／缺氧;快增长率正加速度导致物意识丧失可能与颅内高应力有关,但缺直接的实验证据。用于Ｇ－ＬＯＣ监测的生理指标中,眼水平动脉血压、脑氧饱和度等可能具有重要作用。

国产生长激素治疗生长激素缺乏症的疗效观察

了解国产人生长激素（ｈＧＨ）的治疗效果。方法：对１５例未经生长激素治疗的生长激素缺乏症（ＧＨＤ）病人（均经精氨酸和可乐宁两项生长激素激发试验明确诊断,生长激素峰值均小于 １０ μｇ／Ｌ）应用国产分泌型基因重组人生长激素（ｒｈＧＨ）进行治疗,剂量为０．１ｕ／（ｋｇ·ｄ）睡前脐周皮下注射,治疗时间６个月。结果：１５例ＧＨＤ病人６个月身高平均增长（６．３４±０．９４）ｃｍ,生长速度由治疗前的（３．３３±０．４９）ｃｍ／年增加到治疗后的（１２．６８±１．８６）ｃｍ／年。结论：国产人生长激素治疗效果达到国外同类产品水平,而价格仅为进口产品的１／６左右。可安全有效地用于治疗ＧＨＤ身材矮小病人。     

Smoking and Exposure to Occupational Hazards in 8,304 Workers in Guangzhou, China

This cross-sectional study aimed to describe the pattern ofsmoking in relation to occupational hazard exposure in a workingpopulation in Guangzhou, China. In 1994, data on smoking andoccupational hazard exposure from occupational health recordsof 8,304 subjects aged 35 years or older from 47 randomly selectedfactories were studied. About 49% of the men and 55% of thewomen were exposed to dust, chemicals or other hazards. Theprevalence of smoking was 56.1% in men and in women. The prevalenceof smoking in men was higher in those who were younger, withprimary education or who were workers. In women, those who wereolder, with primary education or in management jobs had highersmoking prevalence. In men and women, subjects who were exposedto occupational hazards had higher smoking prevalence: the highest(71.6%) was found in male workers exposed to dust. Urgent tobaccocontrol measures are needed to prevent the epidemic of smoking-relatedand occupation-related diseases in the workplace in China.     

Dietary salt and blood pressure

Research evidence on the role of dietary sodium in the etiology and pathogenesis of hypertension is briefly reviewed. This matter is assuming new importance at present, given new data on the efficacy of normalization of blood pressure for adults with so-called "mild" hypertension (average diastolic 90-104 mm Hg), hence the need for safe nutritional-hygienic alternatives to years-long drug treatment for millions of people with such hypertension. Two trials by the authors deal with some unresolved questions in this area. The first, a preliminary study, involved 21 lacto-ovo-vegetarian high school students living in a boarding school. With decrease in daily Na intake from 216 to 72 meq for the experimental compared with the control group, red blood cell Na concentration was significantly lower in the former; systolic pressure was slightly but not significantly lower. The second trial, the Primary Prevention of Hypertension, involves over 200 hypertension-prone persons aged 30-44, and explores the ability in the experimental group to reduce blood pressure and prevent development of hypertension by safe nutritional-hygienic means (weight reduction, dietary Na decrease, avoidance of excess alcohol, rhythmic exercise). Initial results at 6 months are presented. Trials on the prevention and control of hypertension by nonpharmacologic means, including reduced Na intake, and involving analyses of the inter-relationships among dietary Na, other dietary factors, Na metabolism, and blood pressure in samples from different population strata, are an important present-day research need.
