人体脚长、脚掌宽与身高相关关系的研究

对489名男女青年进行了脚长、脚掌宽与身高的测量,并记录相关数据,将测量数据输入计算机中进行回归分析,得出脚长、脚掌宽推测身高的直线回归方程,利用脚长推测身高:男性:y=93.55+3.26x,女性:y=130.53+1.41x;利用脚掌宽推测身高:男性:y=130.79+4.18x,女性:y=137.99+2.72x。结果表明,人体脚长、脚掌宽与身高存在一定的线性关系。     

理解政策、把握市场是企业发展基础

纵观医药营销的发展脉络,相继出现过＂产品为王＂、＂利润为王＂、＂医生为王＂、＂渠道为王＂、＂品牌为王＂和＂终端为王＂等理论,但是随着新医改的推进,＂招标＂、＂配送＂、＂物价＂、＂目录＂,成为医药营销的先决条件。在新医改背景之下,2009年医药营销已进入＂政府关系为王＂的时代。所以理解政策与把握市场成为各企业的头等大事。     

男性会阴部手术后伤口暴露疗法与伤口细菌感染和愈合情况的研究

目的 探讨男性会阴部手术后伤口暴露疗法的可行性.方法 选择450例男性会阴部手术患者,其中250例术后伤口采用暴露疗法,200例术后伤口采用传统包扎疗法,术后观察伤口细菌感染和愈合情况,统计出伤口甲级愈合率,伤口细菌感染率,采用x2检验,用SPSS 17.0统计软件计算.结果 伤口甲级愈合率暴露疗法组为92.8%,明显高于包扎疗法组的91.5%（x2=12.2,P〈0.01）.伤口细菌感染率暴露疗法组和包扎疗法组相近（x2=0.06,P〉0.05）.结论 男性会阴部手术后伤口采用暴露疗法不会增加伤口细菌感染率,且伤口甲级愈合率明显提高.

Oestrogen and the cardiovascular system: the good, the bad and the puzzling

The concept that oestrogen replacement therapy is cardioprotective has been challenged recently by the negative results of randomized clinical trials in coronary heart disease. These data have come at a time of rapid advances in our understanding of the cellular mechanisms of oestrogen. In particular, the cloning of the classical oestrogen receptor (ERalpha), the identification of a novel ER isoform (ERbeta), the availability of specific ERalpha and ERbeta knockout mice models, and the elucidation of receptor functions and signalling pathways linked to non-genomic actions of oestrogen are helping to unravel this complex biology. In this article, these advances will be discussed with particular emphasis on the regulation of nitric oxide synthesis by oestrogen. Furthermore, the puzzling issues that have emerged and the potential for development of novel and specific therapeutic approaches will be highlighted.     

Clinical use of the polymyxins: the tale of the fox and the cat

Background

There is a need to identify practice patterns of polymyxin use, quantify gaps in knowledge, and recognize areas of persistent confusion.

Effect of reserpine on the acetylcholine content of the heart, the ileum and the hypothalamus of the dog

The effect of intravenous administration of reserpine in 10 dogs was studied on the acetylcholine content of the sino-atrial node, the right auricle and the right ventricle of the heart, the ileum and the hypothalamus of dog. The general sedation, the bradycardia, and the purgative effects of reserpine were also noted. Tissues were removed for estimation of acetylcholine when bradycardia was maximal. Reserpine increased the acetylcholine content of all the tissues studied. The increase in the peripheral tissues was greater than in the hypothalamus. The bradycardia and the purgative effects of reserpine may be related to the increase of the acetylcholine content of the sino-atrial node and the ileum.     

Organic acid transport to the blood from the corpus striatum, the thalamus and the cerebellum of the rat

Conscious rats were given intracerebral injections by preplaced microsyringes. The injectates were 0.3-0.5 microliters of 125I- and 131I-o-iodohippurate. One hour after injection the isotopes present in the unopened cranial cavity were measured by gamma spectrometry. Some animals received 200 mg/kg probenecid intraperitoneally and this reduced the rate of absorption from injectates into the corpus striatum to 65.7 +/- 12.6% of control; from injectates into the cerebellum to 57.1 +/- 9.8% of control. Dye injections showed that injections into the cerebellum did not remain in the parenchyma, in contrast to injections into the corpus striatum or thalamus. Probenecid was also given as 2.9% solution, pH 7, mixed with the iodohippurate in the microsyringe. It had no effect on injections into the cerebellum, reduced the rate of absorption from the corpus striatum to 80.9 +/- 3.2% of controls and that from the thalamus to 88.3 +/- 2.2%. The results indicate parenchymal probenecid-sensitive transport of iodohippurate from the corpus striatum and thalamus but failed to settle the matter for the cerebellum.

求医疗保险客观规律之真务参保人员身体健康之实

我国医疗保险制度改革已经走过了十年风雨历程,大体经历了四个阶段：1994年开始在镇江、九江(简称“两江”)试点。1996年扩大试点范围(全国参与试点的是40多个城市),1998年国务院作出《关于建立城镇职工基本医疗保险制度的决定》,在全国范围内建立与社会主义初级阶段生产力水平相适应、覆盖全体城镇职工的、社会统筹和个人帐户相结合的基本医疗保险制度。这标志着一项崭新的制度建设、一项宏大的社会系统工程将在中国大地上屹然耸立。

A view from the other side: the hope in the eyes of the healer

A physician affected by amyotrophic lateral sclerosis (ALS) explores the meaning of his disease. The deterioration of his physical health and of his independence provided a new and deeper view of healing, as well as a new mission for his medical profession. He has become at the same time a “voice for the voiceless” and a source of hope and inspiration for patients and health professionals alike. Espousing the principle that healing is always possible even when the disease is incurable, the author proposes a three-prong approach to healing: symptom management, allegiance to the patient up to the ends, and common search of meaning. He emphasizes that both patients and health care workers need to be healed.
