云南省卫生资源配置标准的弹性系数研究

目的　在进行云南省区域分类基础上制定云南省区域卫生资源配置标准标志值后 ,根据云南省各个地区的特点增加不同弹性系数。方法　采用流行病学研究方法 ,收集和分析云南省不同地州市 1990～ 1999年有关人口、社会经济状况及卫生经费的投入、居民健康状况、居民文化、生活水平、少数民族状况、旅游地区、边境线长短及贫困状况等资料。结果　研究结果表明曲靖地区、玉溪市、保山地区增加弹性系数最少 ,分别为 0 67%、 1 5 8%和1 68% ,怒江州、迪庆州和西双版纳州增加弹性系数最多 ,分别为 11 15 %、 10 2 5 %和 9 84 %。其它地区的弹性系数分别为昆明市 5 88% ,昭通地区 2 3 1% ,楚雄州 2 3 0 % ,红河州 7 0 3 % ,文山州 5 5 3 % ,思茅地区 7 4 3 % ,大理州4 94 % ,德宏州 6 78% ,丽江地区 4 3 5 % ,临沧地区 6 13 %。结论　云南省区域卫生配置标准的弹性系数研究为云南省卫生资源区域分类配置标准提供了科学依据 ,不同弹性系数体现了云南省不同地区的卫生资源区域分类配置标准的公平性、合理性及实用性     

33例精神分裂症患者氯丙嗪治疗前后血小板聚集功能

本文对精神分裂症患者用氯丙嗪治疗前后PAg(T)功能进行观察及BPRS评定,发现精分症患者PAg(T)功能明显高于对照组,用氯丙嗪治疗1个月后,BPRS评定分值下降,患者临床症状消除,而PAg(T)第一时相无变化,第二时相明显升高,说明氯丙嗪聚药物可促发血小板释放内源性致聚物质,同时也说明患者PAg(T)异常不仅仅是情绪应激所致,更重要的是血小板生理功能异常。     

Recurrent lens binding and central island formations in a fast-responding orthokeratology lens wearer.

A 12-year-old girl with a history of fast myopia progression underwent advanced orthokeratology (ortho-k) treatment and suffered from recurrent lens binding and central corneal staining. The problem could not be fixed by lens fenestration and refitting with a less aggressive lens (three-zone ortho-k) design. After refitting with a lower target advanced ortho-k lens, these complications were no longer occurring, and the amount of power reduction was greater than expected considering the target designed for the refitted lenses. During the following 15 months of ortho-k lens wear, there was no clinically significant change to her refractive error. The patient and her parents were happy with the outcome, although the refractive error was not totally eliminated and she still needed to wear spectacles for clear vision. Possible etiologies of the complications are discussed.     

Efficacy of minor analgesics in primary dysmenorrhoea: a systematic review

Objective To quantify the efficacy and safety of naproxen, ibuprofen, mefenamic acid, aspirin and acetaminophen (paracetamol) in the treatment of primary dysmenorrhoea through a systemic overview of randomised controlled trials.
Methods MEDLINE, EMBASE and the Science Citation Index were searched for randomised controlled trials. Efficacy was assessed by measurement of pain relief, requirement for rescue analgesics, restriction of daily life and absence from work or school. The rate ratios of side effects were used to assess safety.
Results Fifty-six trials describing 55 comparisons of analgesics with placebo and 12 direct comparisons with other analgesics met our inclusion criteria. Women taking naproxen were over three times more likely to have at least moderate pain relief than those taking placebo. Ibuprofen, mefenamic acid and aspirin were also superior to placebo but acetaminophen was not. The requirement for rescue analgesics, restriction of daily life and absence from work or school were less frequent with naproxen and ibuprofen than placebo but not with aspirin or acetaminophen. Direct comparisons did not show any difference between naproxen and ibuprofen. Side effects occurred more frequently only with naproxen when compared with placebo.
Conclusion Naproxen, ibuprofen, mefenamic acid and aspirin are all effective in primary dysmenorrhoea. Ibuprofen appears to have the most favourable risk-benefit ratio. Acetaminophen appears to be less effective than nonsteroidal anti-inflammatory drugs, but there was only one trial meeting our inclusion criteria and further studies are required.     

吗啡对机械通气病人的应用

为获得病人在接受呼吸机期间充分的镇静、良好的耐管并与呼吸机合拍达到满意的治疗效果，对６０例不同年龄的患者在进行呼吸机支持治疗期间，采用平均０４５ｍｇ／（ｋｇｄ）的吗啡量持续微量泵静脉注入，间断辅助安定的方法．用药后连续２ｈ观察血压、心率、呼吸、意识等变化．结果：在用药期间病人血压、心率、呼吸平稳，保持清醒，安静耐管，解决了病人与呼吸机拮抗的矛盾．结果表明：该法在临床上有广泛使用价值

非痉挛型脑瘫的立体定向手术治疗(附16例报告)

目的探讨立体定向核团毁损术及脑深部电刺激术治疗非痉挛型脑瘫的疗效。方法将16例非痉挛型脑瘫病人分成三组：A组为肌张力障碍型，11例；B组为肌张力障碍合并震颤型，3例；C组为共济失调合并震颤型，2例。采用通用DT评分量表（GPS）评估病肢功能。分别采用立体定向核团毁损术及脑深部电刺激术治疗。术后随访1年，评估症状改善情况。结果A组肌张力障碍改善率为0—58．3％，平均17．1％；B组肌张力障碍改善率6．7％～25．0％，震颤改善率66．7％～75．0％；C组共济失调无明显变化，震颤改善率12．5％～25.0％。结论立体定向手术是治疗肌张力障碍型及震颤型脑瘫的可选择手段。     

视盘血管炎——关于混合型的研讨

对６０例（６３眼）视盘血管炎的临床分型进行了探讨，结果表明，除分为Ⅰ、Ⅱ两型外，尚存在混合型，当视盘睫状血管炎性病变波及中央静脉，或两个血管系统同时受炎症侵犯时，即可再现混合型的临床表现，视盘明显水肿，视网膜静脉迂张，散在渗出，出血，动脉狭细。眼底荧光血管造影可见视盘荧光早期充盈明显迟缓，后期渗漏面积〉２．０ＰＤ，视网膜循环时间延长，混合型兼有Ⅰ，Ⅱ两型的临床特征，应作为一个独立类型存在，同时观察
