环孢霉素A滴眼治疗角膜移植排斥反应

应用0.5％环孢霉素A(cyclosporin A,CsA)滴眼治疗穿透性角膜移植术后发生免疫排斥患者16例(16只眼),治愈9只眼,好转6只眼,无效1只眼。随访5～24个月,其中2只眼因停药复发,1只眼于拆线后复发,继续用药或增加给药次数后治愈。研究表明0.5％CsA滴眼剂治疗术前移植床条件较好,角膜移植术后发生免疫排斥的病例可得到良好疗效;而对术前移植床条件较差,角膜移植术后发生免疫排斥的病例有一定的疗效。作者对眼局部应用CsA治疗角膜移植排斥的疗效和作用机理进行了讨论。     

肝病患者血清透明质酸放射免疫测定的临床分析

检测256例肝病患者HA,结果表明各肝病组均增高,幅度从慢迁肝到慢活肝至肝硬化呈递增,其数值的高低可反映肝脏病变的程度。根据HA与中医血瘀证关系的分析,HA的增高与血瘀证存在明显的正相关关系。     

A型肉毒杆菌毒素治疗麻痹性斜视

采用眼外肌注射A型肉毒杆菌毒素的方法,治疗17例(18只眼)麻痹性内斜视患者。最大的肌肉麻痹作用发生于注射后7～14天,最大斜视矫正度为50-,随访时间为4～20周,5例最终获得双眼视。未见全身副作用。认为,这种疗法可在部分患卉中替代斜视矫正术。     

Partial splenic embolization for hypersplenism concomitant with or after arterial embolization of hepatocellular carcinoma in 30 patients

Purpose To study the value of partial splenic embolization (PSE) for the treatment of hypersplenism in patients undergoing embolization of hepatocellular carcinoma (HCC). Methods Transcatheter hepatic arterial embolization (THAE) combined with PSE was performed in 30 patients with HCC complicating liver cirrhosis, portal hypertension, and hypersplenism. Gelfoam sponge was used as the embolic material for PSE and limited to 100–150 pieces. Results More than 50% of splenic parenchyma was infarcted in 27 patients. Leukopenia and thrombocytopenia were corrected by PSE in 25 of 27 patients with hypersplenism. In 26 patients with esophageal varices, including 5 patients with bleeding, no rebleeding occurred during a 6–17 month follow-up. Hypersplenism was not corrected in 2 of 3 patients whose infarcted splenic parenchyma was less than 50%. No splenic abscesses or other severe complications were observed. Of the 30 patients treated, 19 are still alive after 1 year. Conclusions THAE combined with PSE is a safe and effective measure for patients with HCC.     

The effectiveness of 'nursing beds': a review of the literature

A literature search was conducted to identify 'nursing led in-patient units' where the nurse is the designated leader of the clinical team. The review concentrates on studies which have attempted to measure the impact of nursing-led in-patient units and reviews both the methodology and outcomes. Three major bodies of work were identified. Lydia Hall's evaluation of the Loeb Center for Nursing and Rehabilitation (USA) is reviewed in some detail. This work was the model for 'nursing beds' at the two Oxfordshire Nursing Development Units (UK) in the 1980s. Studies evaluating these centres are reviewed and reports of similar UK units discussed. A third body of work evaluates a nurse-managed critical care environment. Common features include a case mix based on nursing need with nurses having authority to admit and discharge patients. While results are generally favourable, with improved patient independence, fewer readmissions, lower mortality and cost savings reported in some or all of the studies, all studies reviewed demonstrate the difficulties of applying an experimental model to real life clinical services. Methodological limitations render firm conclusions difficult. Techniques adopted from studies in field settings, the so-called 'quasi-experiment', are advocated as a remedy, as is further study of the process of care in investigating this model of care delivery.

目的:了解已婚育龄妇女避孕措施的变化趋势,为指导计划生育服务工作提供科学依据。方法:收集1983~2005年苏州市已婚育龄妇女避孕方法的资料,并用统计软件对其变化趋势进行了分析。结果:已婚育龄妇女节育率在88.38%~92.94%范围波动,长效避孕措施现用率从75.19%下降至71.27%,而短效避孕措施从12.86%上升至17.11%。宫内节育器的现用率从50.09%上升到66.50%;避孕套从1.94%上升到14.21%;其他避孕方法的现用率均呈下降趋势,其中女性绝育现用率从24.42%下降到4.50%。结论:节育率维持在较高水平;长效避孕措施现用率下降而短效避孕措施现用率上升;避孕方法使用趋于多样化,需要提供满足个性化需求的指导和服务。     

Milgram and Tuskegee—Paradigm Research Projects in Bioethics

This paper discusses the use of the Milgram obedience experiments and the Tuskegee syphilis study in the bioethical literature. The two studies are presented and a variety of uses of them identified and discussed. It is argued that the use of these studies as paradigms of problematic research relies on a reduction of their complexity. What is discussed is thus often constructions of these studies that are closer to hypothetical examples than to the real studies.     

Rapidly progressive parkinsonism in a self-reported user of ecstasy and other drugs.

A 38-year-old man developed parkinsonism that progressed to Hoehn and Yahr stage 5 within 4 years of onset. Response to ropinirole deteriorated, levodopa was not tolerated, and subthalamic nucleus stimulation has provided only partial relief of symptoms. He reported heavy use of Ecstasy through most of his twenties and thirties. His neurological problems may be unrelated to his drug use, but it is also possible they represent an idiosyncratic reaction.     

美托洛尔治疗高血压病的疗效及其耐受性

原发性高血压患者425例(男252,女173;年龄60±s12a)采用美托洛尔100mg,po,每晨1次,4wk为一个疗程。总有效率82.4％,治疗2wk后血压继续下降,心率并不继续减慢。不良反应主要为心率减慢后的症状及神经系症状,停药率6.4％。60a以上的患者总有效率及停药率与中、青年患者无明显区别。故美托洛尔同样适用于老年人。
