中国近代西医产科学史

本文阐述了中国西医产科学的发展历史。由于传统封建思想的阻碍,我国现代产科学的起步较晚,１９１１年在福建省建立了我国第一所产科病房。１９３０年以前孕产妇及新生儿死亡率比英美高４～５倍,１９３０年后,建立助产学校,开展孕期保健及骨盆测量,不断改进对病理妊娠的诊断及妊娠合并症的处理,这些均促进了中国近代西医产科学的进步,也为建国后的发展奠定了基础。     

Early one-stage orthotopic jejunal pedicle-graft interposition in long-gap esophageal atresia

Since 1988, four children with long-gap esophageal atresia have undergone one-stage orthotopic jejunal pedicle-graft interposition at the age of 2 to 3 months. Obtaining enough jejunal length was no problem and major early complications did not occur. In one patient stenosis of the distal anastomosis was problematic and required corrective surgery. None of the patients demonstrated jejunitis as a result of gastroesophageal reflux. With follow-up periods of 12, 27, 46, and 60 months, all patients are doing well. It is concluded that the jejunum is a better esophageal substitute than is generally appreciated.     

Identification of the central vestibular projections in man: a positron emission tomography activation study

The cerebral representation of space depends on the integration of many different sensory inputs. The vestibular system provides one such input and its dysfunction can cause profound spatial disorientation. Using positron emission tomography (PET), we measured regional cerebral perfusion with various vestibular stimulations to map central vestibular projections and to investigate the cerebral basis of spatial disorientation. We showed that the temporoparietal cortex, the insula, the putamen, and the anterior cingulate cortex are the cerebral projections of the vestibular system in man and that the spatial disorientation caused by unilateral vestibular stimulation is associated with their asymmetric activation.     

上海市儿童单纯性肥胖的调查

目的了解上海市学龄儿童肥胖发生率、肥胖对血压的影响以及肥胖影响因素,为预防儿童肥胖制订防制策略及措施提供基础资料。方法整群抽取１７５１名７～１１岁学龄儿童,测量身高、体重及血压等指标,并按统一编制的调查表进行问卷调查。结果肥胖检出率１４．０５％,其中男性高于女性,分别为１５．６７％和１２．２６％,差别有显著性（Ｐ＜０．０５）。肥胖儿童高血压检出率４．８８％,明显高于非肥胖儿童０．１９９％,差别有高度显著性（Ｐ＜０．０１）。喜食肥肉及油腻性食物、吃饭速度快者,肥胖检出率高。结论上海市儿童单纯性肥胖检出率似接近发达国家水平,肥胖儿童中高血压者明显增多。应指导家长对儿童进行合理饮食,平衡膳食,减少肥胖症发生。     

综合治疗对脑梗塞相关危险因素的影响

目的　探讨综合治疗对脑梗塞复发的相关危险因素的影响。方法　随机选择85 例脑梗塞伴各类危险因素患者在综合治疗前后,对他们进行血压、空腹血糖、胆固醇、甘油三酯及血液流变学等8 项指标的测定。结果　经过1 ～3 年临床观察随访,有50 % 以上高血糖、高血脂、高粘滞血症患者检验指标趋于正常,94 .3 % 的高血压得到控制与稳定,经t 检验,血液流变学4 项P 值< 0 .05 ,差异有显著意义,高血压、空腹血糖、胆固醇、甘油三酯的P 值< 0 .01 ,差异有非常显著意义。结论　综合治疗对控制相关危险因素,预防脑梗塞复发有重要临床意义     

Poorer nutritional status of the older-generation in a Japanese farming village, as related to fewer types of food consumed

This study was carried out to determine whether the most recent nutritional improvements in Japanese farming villages were due to improvement in the diet of the young only or across all ages. Food duplicates for 24 h were collected. The number of food items and the adequacy of each nutrient level were compared between subgroups, by age of cooking and those eating meals. The older-generation used and ate fewer food items resulting in poorer nutrition. The most recent improvement in nutrition in the farming villages of Japan was found mainly to affect the younger-generation with the older-generations being more poorly nourished.     

Sleep, age, and shiftwork experience

The effects of age and shiftwork experience (never, past, present) on sleep were studied in a sample of 3236 wage earners and retired workers by means of a questionnaire. The sample was composed of 32-, 42-, 52-, and 62-year-old subjects, and included both sexes and various occupational statuses. Age resulted in a continuously increasing frequency of sleep disturbances and hypnotic use, except for difficulty getting back to sleep and early awakening, which peaked at 52 years and then decreased at 62 years, thus suggesting a 'retirement effect'. Current and past shiftworkers reported more problems with falling asleep and early awakening than subjects who had never worked on shifts. This is a likely explanation of why the effect of age was massive in the latter group and much less pronounced in the former groups. There were no clear effects of the length or recency of shiftwork experience. This finding does not support the hypothesized permanent effect of shiftwork experience on subsequent sleep. Females had higher complaint rates at every age. There was little interaction between age and sex, but women were affected more by shiftwork as they got older, particularly as to hypnotic consumption. Some of the results support the hypothesis that a selection process excludes workers who are no longer able to cope with the demands of shiftwork.     

Soluble E-selectin correlates with disease activity in cyclosporin A-treated patients with atopic dermatitis

BACKGROUND: The expression of adhesion molecules on endothelial cells regulates leukocyte migration. The level of soluble adhesion molecules which are shed into the circulation is known to reflect the degree of inflammation, and this level can therefore be used as an indicator of disease activity. The objective of this study was first to investigate the relationship between sE-selectin levels and disease activity parameters (scores of extent, severity, itch, and sleep) in atopic dermatitis (AD) patients, and second to determine the effect of therapy with an immunosuppressive drug (cyclosporin A) on sE-selectin levels. METHODS: Fourteen patients with severe AD and 41 healthy controls were studied. sE-selectin was measured by ELISA both 2 weeks before therapy with cyclosporin A and after 16 weeks of treatment. RESULTS: At baseline, the level of sE-selectin was significantly higher in patients with AD than in healthy control subjects (P<0.0001). After treatment of AD with cyclosporin A, there was a significant reduction of the sE-selectin levels (P<0.0001). In addition, changes in sE-selectin levels significantly correlated with changes in disease activity parameters such as severity (P<0.002) and extent of disease (P<0.049). CONCLUSIONS: Soluble E-selectin is a new serologic marker in AD which reflects disease activity. Therefore, soluble E-selectin may be a useful parameter in the monitoring of this disease.
