了解北京市农村居民医疗费用情况。方法：分4个季度调查农村居民医疗卫生服务需要及利用情况，同时调查三级医疗机构门诊及住院病人的医疗功用。结果：农村居民年人均医疗费用80．95元，其中老年人为166．01元，居民年人均医疗费用最高的疾病为感冒及心脑血管病。结论：建议加强农村老年保健工作，发展和完善农村合作医疗制度。     

Leukemia clusters around nuclear facilities in Britain

He bas been retained for the defense by British Nuclear Fuelsplc in two suits in which leukemia and non-Hodgkin's lymphoma have been alleged to result from radiation exposures due to the operation of the nuclear reprocessing plant at Sellafield. This paper has been sent to the senior authors of the papers reporting clusters of leukemia or other malignancy in the vicinity of nuclear facilities in Britain and their comments invited. Subject to considerations of space and CCC style, these comments will be published as submited.     

How Cluster Headache is Explained as an Intracavernous Inflammatory Process Lesioning Sympathetic Fibers

SYNOPSIS
A large body of evidence points to an inflammatory process in the cavernous sinus and tributary veins as being primarily responsible for cluster headaches. The inflammation obliterates the venous outflow from the cavernous sinus on one side and injures the through-running sympathetic fibers to the eye, upper eye lid, forehead skin, and the intracranial internal carotid artery and its branches. The active period ends when the inflammation is suppressed and the sympathetic fibers partially or fully recover. Evidence is presented that the symptoms suggestive of an enhanced parasympathetic activity during attacks may alternatively be explained as local pain fiber activation or a stasis in the outflow from the cavernous sinus. Vasodilator agents like nitroglycerin induce an attack by enhancing the venous load on the cavernous sinus. Constriction of the proximal intracranial internal carotid artery, spontaneously induced by tressful pain activation of the perivascular sympathetic nerves, or by exogenous administration of serotonin 1 D-like receptor agonists or oxygen, terminates the venous load and thus the pain and associated symptoms.     

大叶牛奶菜孕甾甙成分研究

用硅胶层析及反相硅胶层析法，从大叶牛奶菜（MarsdeniakoiTsiang）抗生育活性的甲醇提取物中分离获得一孕甾四糖甙。经化学反应，波谱分析，酸碱降解及其水解产物的鉴定，确定其结构为12-0-cvnnamyl-dihydrosarcostin-3-0-β-D-glucopyranosyl（l→4）-0-3-0-methyl-6-deoxy-β-D-allopyranosyl(1→4)-0-β-D-oleandropyranosyl(1→4)-0-β-D-cymaropyranoside,命名为大叶牛奶菜甙庚（marsdekoisideG）。经系统文献检索证明其为首次自该植物中分离得到。     

氟西汀治疗持续的躯体形式疼痛障碍的成本-效果分析

目的 初步探索氟西汀治疗持续的躯体形式疼痛障碍(PSPD)的成本-效果分析.方法 将80例PSPD患者随机分为氟西汀组和安慰剂组,每组各40例,分别服用氟西汀胶囊(20 ms/d)和安慰剂胶囊(1粒/d)8周,研究者和患者双肓.调查入组前后直接医疗成本,计算两组患者入组前后共4个月的成本与效果比值.结果 (1)氟西汀组有效率为40%,安慰剂组有效率为8%.(2)氟西汀组和安慰剂组成本与效果比值分别为0.53万元(5345元)和1.83万元(18 345元).(3)敏感度分析,氟西汀组和安慰剂组的成本与效果比值分别为0.40万元(4033元)和1.22万元(12 188元).结论 应用氟西汀治疗PSPD的成本与效果比值较低,具有较好的药物经济学价值.

战伤绿脓杆菌感染源及防治研究

本文对云南老山前、后方医院环境及战伤感染标本中绿脓杆菌(简称PA)进行调查,对所分离的333株PA进行血清学分型及药物敏感性测定。结果可看出除炸伤时创口易被泥土中PA污染外,前、后方医院环境也是感染源之一。提示各级医疗单位在战伤救治中对PA的监控十分重要。本文结果直接有益于前、后方医院对战创伤PA的防治。     

对医院药事管理委员会系统工程管理的初探
