眼内异物合并外伤性白内障的联合手术治疗：附88例分析

眼内异物合并外伤性白内障是眼外伤常见的致盲原因之一,各地报告的致盲率为20%～48.9%。本文对88例眼内异物合并外伤性白内障患者采用联合手术治疗,收到较好疗效,术前视力0.05以下占85.2%,术后矫正视力0.05以下占27.3%,矫正视力0.06～1.5占73.7%,其中矫正视力0.6～1.5者占22.8%。根据异物的性质、在眼内部位和晶体损伤情况选择不同的手术方式一次联合手术摘出异物和白内障,术后采用中西药配合治疗。联合手术可提高疗效,减少术后并发症.减少手术次数,减轻病人的痛苦,缩短病程,减少医疗费用.眼科学报1993;9:216—218.     

Effects of ethmoidal nerve stimulation on respiration-related neurones in the dorsal medulla of the cat

Stimulation of the nasal mucosa produces a number of respiratory reflexes the afferent limb of which is provided by the ethmoidal nerve, a branch of the trigeminal nerve. In the cat this nerve terminates within the trigeminal nucleus. It has no direct projection to brainstem respiratory centres. This study examines the response of respiratory-related neurones in the nucleus of the solitary tract (NTS) to ethmoidal stimulation. It demonstrates that these neurones show both excitatory and inhibitory responses to ethmoidal stimulation. Thus, the NTS appears to be involved in respiratory reflexes initiated by stimulation of the nasal mucosa.

conference report: Mental health and intellectual disability: an international perspective

The present paper reports on the inaugural meeting of the Mental Health Special Interest Research Group (SIRG) of the International Association for the Scientific study of Intellectual disability which was held at Fitzwilliam College, Cambridge, UK, in March 1998. The meeting was organized in conjunction with the Ninth Annual SIRG on ageing and intellectual disability. Representatives from North America, several European and Scandinavian countries, Australia, and Israel attended. Two broad themes had been determined prior to the meeting: ‘Improving the detection of mental health problems’ and ‘Research strategies for identifying risk factors for mental health problems’. In the presentations and subsequent discussions, it was apparent that there were extrenely diverse perspectives both across and within the different countries represented. Not only were individuals' experiences very different, but most strikingly, the theoretical frameworks were very diverse. This was partly a function of there being understandable differences in perspectives across disciplines, but at its most marked, there were fundamental differences in the way both intellectual disability and mental health were conceptualized.     

Functional restoration in chronic low back pain

Conventional treatments have not slowed down the ever expanding low back pain (LBP) problem. Traditional treatment has most probably contributed to the growth of the problem. Therefore, in a search for new solutions, 'functional restoration' has been devised. In connection with chronic LBP the term has been associated with a full-day program lasting from 3 to 5 weeks. it includes multidisciplinary treatment of patients in groups with intensive physical and ergonomic training, psychological pain management, back school, as well as teaching in social/work related issues. The key concepts are 'acceptance of the pain', 'activity', 'self-responsibility', 'multidisciplinary' and 'quantitative functional evaluation (QFE)'. The latter is aimed so that the participants can feel the physical improvement, encouraging them to be able to go back to work, or at least to lead a more active life style. Several controlled studies suggest a lasting effect in terms of regaining their ability to work and improving pain behavior for a good part of disabled chronic LBP patients. However, it is noteworthy that randomized studies seemingly show poorer results than studies not employing randomized controls.     

全喉切除术中保留甲状软骨膜对手术进程和术后恢复影响的探讨

目的：探讨保留甲状软骨膜对全喉切除手术进程和病人术后恢复情况的影响。方法：在甲状软骨膜下游离甲状软骨并切断其上角。不结扎和切断舌骨下肌群和喉上动脉。保留之甲状软骨膜用以加强修复咽壁黏膜。结果：本组病例较经典全喉切除术手术时间缩短30min以上。手术中出血在100ml以下。患者术后第2d下床活动，第4d开始进食流质。手术创口均一期愈合。结论：全喉切除术中保留甲状软骨膜可有效地简化手术步骤，减少创伤和出血。利用甲状软骨膜加强咽壁黏膜缝合口，进一步减少了咽漏的发生.     

装潢居室空气中挥发性化学物的遗传毒性研究

目的探讨装潢居室空气中挥发性化合物的遗传毒性.方法采用小鼠骨髓嗜多染性红细胞微核试验和小鼠精子畸形试验检测居室装潢后空气中挥发性化合物的遗传毒性.结果该化合物对小鼠呼吸系统有明显的刺激作用,与阴性对照组比较,高、中、低剂量组的微核率、精子畸形率均有显著差异性.结论居室装潢后室内空气中挥发性化合物具有遗传毒性作用.
