大学生手机短信消费心理研究

通过自编调查问卷，对400名大学生的手机短信消费情况进行调查和分析，结果发现：①手机短信已成为当代大学生普遍流行的一种交际手段，并更多地在较亲密的群体内部使用，方便和费用低是大学生选择短信进行交际的主要原因；②大学生的手机短信消费具有显著的性别和年级差异；③部分大学生在短信消费中形成了一定的手机依赖和幻听等心理和行为问题。

[目的]了解肿瘤用药的消费现状及发展趋势，为临床合理用药提供依据。[方法]对本院1996年-2002年抗肿瘤药、生物反应调节剂和升白细胞药的用药情况进行统计分析，以药品的年消耗金额作统计。[结果]抗肿瘤药、生物反应调节剂和升白细胞药分别占全部药品年消耗总金额的24．24％～33．73％、15．80％～23．33％和5．86％～9．11％。[结论]抗肿瘤药、生物反应调节剂和升白细胞药是用于肿瘤治疗的主要药品，尤其是抗肿瘤天然药物有着广阔的应用前景。     

论公费医疗大额死亡病例的资源消耗与医学目的

从北京市公费医疗大额消耗的９２例死亡病例的费用结构及住院城数的统计，提示由住院日地长，贵重卫生资源的盲目过量投入等而致。这与中国国情不符。因此，医学目的概念应更新，以及应如何正确对待死亡病例的医疗服务值得进行讨论。     

Local blood flow and metabolism of the tongue before and during panting in the dog

Summary The effects of hyperthermia on blood flow and oxygen consumption of the tongue were investigated in anesthetized dogs. For comparison, blood flow through the skin and deep muscle of the hind leg was also measured in some animals. Increasing blood temperature revealed a biphasic response of lingual blood flow. At 41°C blood temperature respiratory frequency was twice that of control and there was a reduction of lingual blood flow, while resistance of the lingual bed was increased significantly. The arterio-venous oxygen difference (AVDO₂) of lingual blood was markedly increased at this level and the of the tongue was like-wise significantly greater than control. At 41.9°C, the steep increase of respiratory frequency was accompanied by a marked fall in lingual resistance as evidenced by a four-fold increase of lingual blood flow. The systemic AVDO₂ rose at this temperature, while the lingual AVDO₂ fell dramatically. There was no further increase of lingual . At both temperature levels the blood flow through the skin did not change substantially, while the deep muscle blood flow slightly increased. The mean arterial pressure showed a progressive fall during hyperthermia. It is assumed that the decrease of lingual blood flow at elevated blood temperature without panting is due to a redistribution of cardiac output to areas other than the tongue. The increase of lingual blood flow without an additional increase of lingual during panting may be explained solely as a mechanism for heat dissipation. The fact that the decrease of lingual resistance was demonstrated in immobilized animals concomitant with high frequency phrenic burst activity suggests that the decrease of lingual resistance and panting may be induced by a common central integrating mechanism.     

Effect of hypothermia on renal sodium reabsorption

Summary The relationship between sodium reabsorption and oxygen consumption was studied in an isolated rabbit kidney preparation perfused with blood at 37, 28 and 19° C. When the temperature was lowered from 37° C to 28° C and to 19°C the rate of oxygen consumption and of the maximal P.A.H. excretion (Tm P.A.H.) decreased more than that of sodium reabsorption.TheQ ₁₀ for sodium reabsorption is about 1.8, while that for maximal P.A.H. excretion is 2.5. Some hypothesis on the possible mechanisms of the lowQ ₁₀ of the Na⁺ reabsorption are forwarded.Preliminary reports have been published [Boll. Soc. Ital. Biol. Sper.43, 1019–1023 (1966) and44, 1784–1787 (1967);45, 860–862 (1969) and45, 863–865 (1969)].     

健康婴幼儿早期教育的效果及影响因素

目的:探讨健康足月婴幼儿早期教育(简称早教)的效果及其影响因素,为开展健康足月婴幼儿早教工作提供理论和实践依据.方法:以自愿来早教中心进行早教的健康足月婴幼儿52名为实验组.另选择与其基本条件相同的婴幼儿52名为对照组.实验组除进行早教的各项培训工作外,还于培训前和培训3、6、9个月后各测评发育商(DQ)1次,以评定早教的效果.对照组无早教,于入组时和9个月后各测评DQ 1次.结果:①实验组经培训9个月后,其DQ平均值提高21.9±13.6分,高于对照组观察9个月后DQ平均值提高分3.0±3.0,差异有统计学意义(t=9.757,P＜0.001).②实验组培训前DQ值有23例低于中等水平;培训后有27例高于中等水平,其中8例DQ≥130.③多元逐步回归分析结果表明,影响DQ增加的主要因素是完成家庭训练作业的程度(R2=0.57),其次是到早教中心训练的次数(R2=0.019),再次是性别(R2=0.016).结论:早教对健康足月婴幼儿的大脑发育、智能发展、运动发育具有显著效果,是提高婴幼儿DQ的有效措施.

秩和的分布,区间估计和假设检验的探讨

目的 探讨秩和比的分布理论及建立区间估计和假设检验方法。方法 假设各变量相互独立,观察单位某变量取值是随机的,则其秩的分布为均匀分布,秩和的分布是m个独立同分布变量之秩的和。结果 当m和n较小时,如m<3,秩和的分布呈单峰对称分布;m和n不太小时,秩和的分布迅速逼近正态分布。结论 对秩和与秩和比可以应用正态分布理论作区间估计和假设检验。
