Treatment of ulcerative colitis by traditional Chinese medicine and dynamic study of immune functions

The effect of the traditional Chinese medicinal herbs enema and enteric-coated capsules in the treatment of ulcerative colitis (UC) were compared in 260 cases. The immune complexes and the dynamic change of autoantibodies were monitored in 28 out of the 260 cases before and after treatment. The following results were observed. (1) There was no significant difference in the total effective rate between the enema group and the oral capsule group (93.3% and 87.5% respectively), but the recovery rates of purulent hemafecia, mucusfecia and erosion accompanying colitis, etc. in the former group were higher than those in the latter (P less than 0.01). (2) The circulating immune complexes were found 43 times above the normal range in 17 cases with positive rate 60.7%, and tended to decrease as the condition became better after treatment. Antinuclear antibodies were determined by the indirect fluorescent immune method and the indirect enzyme labelling method and the positive rates were 53.6% and 64.7% respectively, both being much higher than those in the controls (P less than 0.01).     

Intrapartum fetal heart rate patterns and neonatal intraventricular hemorrhage

A goal for the obstetrician and neonatologist is to screen for risk factors associated with intraventricular hemorrhage (IVH) in the low-birthweight infant. Perinatal events that lead to neonatal metabolic and cardiovascular derangements seem to provoke IVH, and conflicting reports have implicated labor as being contributory. A fetal heart rate (FHR) abnormality during premature labor may be a predictor of subsequent neonatal IVH. For this reason, 5 years of FHR tracings at two university medical centers were reviewed for inborn infants who were delivered after premature labor and weighed less than or equal to 2000 gm. Sixty-four infants developed IVH, but pre-existing labor with a discernible FHR pattern was recorded in only 38 (59%) cases. Interpretations were reassuring in 17 (45%) cases, suspicious in 7 (18%) cases, and ominous in 14 (37%) cases. This proportion of FHR patterns was not significantly different from a matched group of premature infants without IVH during the same period. Interpretations of intrapartum FHR patterns of low-birthweight infants are limited, especially before 30 weeks gestation, and not useful in predicting neonatal IVH.     

抓住机遇构建和谐发展的疾病防控体系

近几年，国家加强了对突发公共卫生事件应急反应能力的要求，人民群众的防病意识不断增强，疾病控制中心传统工作模式受到了极大挑战。吉林省疾病预防控制中心作为省直卫生系统人事制度改革试点单位，于2003年11月初开始，历经2个月时间圆满完成了单位人事制度与分配制度改革工作，取得了令人满意的效果。现将我们的做法与体会总结如下。     

Treatment of severe diarrhoeal dehydration in hospital and home by oral fluids

This paper reports on 1330 infants, from birth to 24 months old, suffering from diarrhoea and moderate to severe dehydration who were hospitalized in Tehran University Hospital over a period of 11 months. Fifteen per cent of them had signs of shock and 36% had marasmus. All patients were treated orally in two phases: rehydration therapy and maintenance therapy. For rehydration, an isotonic fluid (sodium 80 mmol l-1, potassium 20 mmol l-1) was administered at a rate of 40 ml kg-1 h-1 until all signs of dehydration disappeared. Following complete hydration, the patients were discharged and maintenance therapy was performed at home, by mothers, administering Maintenance Solution (sodium 40 mmol l-1, potassium 30 mmol l-1) ad libitum. Intravenous fluids were not used, even in severe dehydration. The efficacy and safety of this regimen were confirmed by rapid and successful rehydration in 99.7% of the patients and correction of a wide variety of electrolyte abnormalities present on admission, though some relapsed. The study suggests that this protocol could be employed in varied types and severities of dehydration and electrolyte abnormalities, and could also be used in both well nourished infants and in those with severe marasmus. It also demonstrates that mothers can serve as effective health workers and can perform successful maintenance therapy. Nine per cent of treated children required readmission to hospital within 24 h of discharge and a further 8% were hospitalized elsewhere with recurrent symptoms.
