Observation on 108 Normal Ophthalmic Arteries in 80 Patients by Digital Subtraction Angiography

By digital subtraction angiography(DSA), the authors made observations on 108 normal ophthalmic arteries in 80 patients with regard to the origins, courses, branching, morphology and anastomoses of the vessels. The merits and demerits of DSA in observing the ophthalmic artery were discussed. Eye Science 1994; 10: 157- 162.     

氟对人体T细胞数目的影响及硼砂拮抗作用的观察

将３８例地氟病人分为硼砂治疗组和治疗对照组，通过对病人外周血Ｔ淋巴细胞亚群含量的检测，观察了氟对人体Ｔ３、Ｔ４、Ｔ８淋巴细胞含量的影响以及硼砂的拮抗作用。结果表明，在本研究条件下，地氟病人外周血Ｔ３、Ｔ４淋巴细胞数目明显减少，硼砂对此变化无明显的拮抗作用。     

汽车驾驶员心电多相频谱分析

对１１７例汽车司机应用ＨＢＤ－１心电多信息诊断仪进行心电多相频谱分析，其功率谱，传递相移，幅度直方图等五项指标总分阳性率明显高于对照组，随着驾车年限的增加，总分阳性率有升高趋势，心电频谱分析对２３０例冠心病病人阳性检出率８４．７８％。研究认为汽车司机是易发高血压，冠心病的危险人群，该方法在冠心病的环境流行病学研究中具有重要的临床，亚临床意义。     

An analytical framework of physician productivity and variation in utilization.

The utilization of medical services by patients is an important determinant of doctor productivity, but this factor does not appear to have been given much attention in previous studies. In order to answer the question of why is there a wide variation in doctor output at low level medical facilities in China, an analytical framework of doctor productivity and utilization is developed. The simulation model is used to produce data that can be analyzed by such a framework. Great uncertainty about patient flows is one reason for the average lower and varying doctor productivity in lower level health facilities. Until uncertainty can be reduced, more flexibility is needed at the lower level to cope with changing utilization patterns and patient characteristics. The management by doctors of non-patient care activities (preventive programmes, medical research, teaching, and administration) is crucial to any approach to using doctor resources more effectively and efficiently.     

人乳头瘤病毒感染超微结构观察

本文对5例典型尖锐湿疣标本及10例可疑人乳头瘤病毒感染标本进行透射电子显微镜观察。结果典型尖锐湿疣标本中仅1例于细胞核内见到人乳头瘤病毒,排列规则呈结晶状。其余14例标本的细胞内均见不同程度的由病毒感染所引起的非特异性病理变化。本文对人孔头瘤病毒及受感染细胞的超微结构进行了初步探讨。     

Effect of cholestyramine on the formation of pigment gallstone in high carbohydrate diet-fed hamsters.

This study was designed to investigate the effect of cholestyramine on the formation of pigment gallstones in high carbohydrate diet-fed hamsters and whether that effect occurred because of cholecystokinin action. Forty seven hamsters were divided into three groups: group I(n = 16) was fed on normal rodent chow(43% carbohydrate), group II(n = 14) was fed on a high CHO diet(65% carbohydrate), group III(n = 17) was fed on a high CHO diet containing 4% cholestyramine. Gallstones developed in 0% of group I, 42.9% of group II and 5.9% of group III(P < 0.05, group II vs III). To evaluate the chronic status of cholecystokinin level, the wet weight of pancreas and the average area of pancreatic acinar in microscopic high power field were measured. There was no significant difference between group II and group III in pancreatic weight and average area of pancreatic acinar(P > 0.05). In gallbladder bile analysis, there was also no significant difference between group II and group III in cholesterol, phospholipid, total calcium, total bilirubin and bile acid levels. In conclusion, cholestyramine decreases the frequency of pigment gallstone formation in high CHO diet-fed hamsters, but it is not clear whether the mechanism of cholestyramine decreasing the gallstone formation is due to the action of cholecystokinin.     

植物神经癫痫52例脑电图分析

报道52倒6个类型植物神经癫痫,重点分析了脑电图的变化,脑电图异常率100％,69.4％的病例出现两侧阵发性4～7Hzθ节律及6和14Hz阳性棘波,提示中线深部有功能紊乱,亦支持丘脑及脑干部有病变。此外蝶骨电极能提高脑电图对本病的阳性诊断率,值得采用。本文证明脑电图对植物神经性癫痫与非癫痫的鉴别诊断,具有肯定的价值。     

在医疗纠纷案件中医疗机构应注意的问题

我们广大医疗机构,特别是三级甲等医院承担着繁重的医疗、保健和防疫等任务,许多医务人员是满负荷甚至超负荷地工作,出个把失误在所难免,作为法官,我个人对这些都能理解,但是作为患者,疾病对于他们来讲就是一件大事,有些甚至是天塌下来的事。他们抱着对医疗机构、医生的信任前来就医,把自己的生命健康交到医生手上,如果因为医生的疏忽导致不良损害的发生,对这个患者来说,就是100%,不仅造成患者本身的痛苦和伤害,还可能会对患者家庭、甚至社会造成损害,所以必须最大限度地避免由于我们的问题造成患者的不良损害的发生。     

A systematic review of outcomes assessed in randomized controlled trials of surgical interventions for carpal tunnel syndrome using the International Classification of Functioning, Disability and Health (ICF) as a reference tool

Background  

A wide range of outcomes have been assessed in trials of interventions for carpal tunnel syndrome (CTS), however there appears to be little consensus on what constitutes the most relevant outcomes. The purpose of this systematic review was to identify the outcomes assessed in randomized clinical trials of surgical interventions for CTS and to compare these to the concepts contained in the International Classification of Functioning, Disability and Health (ICF).
