米索前列醇用于晚期妊娠引产随机对照研究 总被引:2,自引:0,他引:2
为探讨米索前列醇用于晚期妊娠引产的效果及安全性 ,采用随机对照研究的方法对 2 85例足月孕妇 (孕周 38~ 42 )进行观察研究 ,米索前列醇组 140例 ,用 2 5μg米索前列醇 (以下简称米索 )阴道后穹隆上药 ;对照组 145例 ,催产素静脉滴注引产。结果 :米索引产组 (实验组 )引产成功率 97.14% ,明显高于对照组 82 .75 % (P<0 .0 5 ) ;实验组诱导产兆时间及总产程的时间明显短于应用催产素的对照组 ,差异有统计学意义 (P<0 .0 1)。两组的胎儿、新生儿情况、产后出血、产道撕伤、产后感染均无显著性差异。结论 :2 5μg米索阴道用药用于晚期妊娠引产的方法简单、可靠、安全 ,值得推广。 相似文献

A method is described for investigating life course influences on health in early old age. The lives of some 300 individuals at present aged 65-75 y have been reconstructed from the archived records of a pre-WWII survey, in which they took part as children, and from lifegrid interviews with the same individuals 60 y later. Despite loss to study at several points those interviewed are shown to be representative of the British population socio-demographically, in comparison with the 1931 and 1991 decennial censuses, and physically, in comparison with the Health Survey for England. Bias is conservative because the most disadvantaged were disproportionately affected by loss to follow-up through death and because non-responders to interview were more disadvantaged as children than the interviewees. Representativeness and conservative bias, it is argued, justify the use of these data for investigating life course influences on health in early old age. 相似文献

眶上神经的走行层次及其临床意义 总被引:1,自引:0,他引:1
目的探讨眉区和额部不同手术层面眶上神经的保护方法。方法在15例成人头部标本上,对眶上神经在眉区和额部的行程、走行层次和入肌点的位置进行解剖观测。结果眶上神经出眶上孔后,以52.8±7.4°角向外上经额肌筋膜附着处入帽状腱膜下隙,达发际附近穿帽状腱膜和额肌至皮下。眶上神经起始部直径1.4±0.3mm,本干入肌点至眶上孔的直线距离为40.2±9.1mm,水平距离和垂直距离分别为30.5±8.8mm和33.8±8.4mm。结论根据手术层面的不同,额眉区的深层面手术应注意保护眶上神经 相似文献

Franz M Lieberz K Schmitz N Schepank H 《Social psychiatry and psychiatric epidemiology》1999,34(12):651-656
Background: Our epidemiological study demonstrates the spontaneous long-term course of predominantly psychosocially influenced (“psychogenic”)
disorders (neurotic spectrum disorders, personality disorders, stress reactions and somatoform disorders) in a representative
community sample of the normal adult population of Mannheim, an industrial and university town in Germany. The natural spontaneous
course of these disorders in a population sample over a long period remains largely unknown. Method: Beginning in 1979 (n
t1 = 600) a random population sample was investigated three times over a mean period of approximately 11 years. The last follow-up
study ended in 1994 (n
t3 = 301). The follow-up sample was representative of the t1 sample. Psychodynamically trained and clinically experienced interviewers
used a semi-structured interview and standardized clinical and psychometric instruments. Psychogenic impairment was assessed
using a standardized expert rating (Impairment Score, IS). Results: The mean sum-score of psychogenic impairment after 11 years exceeded the value at t1. The case rate (point prevalence, ICD
diagnosis + clinical cut-off/IS) increased from 21.6% at t1 to 26.2% at t3 in the investigated follow-up sample. Intra-individual
correlation of psychogenic impairment between t1 and t3 was high (r = 0.55). We found strong evidence for an unfavorable long-term course of psychogenic impairment and only a weak tendency
(23.1%) for spontaneous remission of clinically relevant psychogenic impairment. Within a regression model clinical variables,
childhood development conditions and personality traits at t1 predicted psychogenic impairment at t3. Conclusion: All clinical variables conclusively indicate an unfavorable spontaneous long-term course of psychogenic impairment. Together
with the well-known high prevalence of psychogenic disorders in the normal population, this underlines the need for early
therapeutic and preventive intervention.

Application of Akaike's information criterion (AIC) in the evaluation of linear pharmacokinetic equations 总被引:13,自引:0,他引:13

According to linear pharmacokinetics, the time course of plasma concentration of a drug, Cp,is expressed by a sum of exponential functions, Cp=

.This article describes a statistical technique to estimate the number of exponential terms, n,for the time course of drug by the application of Akaike's information criterion (AIC). Plasma concentrations of ethoxybenzamide, sulfisoxazole, bishydroxycoumarin, and diazepam measured following bolus intravenous injection were used as clinical examples for this method. Selection of models is compared between the AIC method and an Ftest method at significance levels of 5% and 1%. 相似文献
