米非司酮合并米索前列醇房事后避孕临床多中心研究

在黄体早、中、晚期应用米非司酮合并米索前列醇与单用米非司酮进行房事后避孕临床多中心比较性研究。５４１名自愿接随机序号参加本研究的健康、月经规律妇女，组Ⅰ口服米非司酮２５ｍｇ，ｑ１２ｈ共４次，第三天上午加服米索前列醇０．４ｍｇ，妊娠率为０．４％。组Ⅱ单服米非司酮２５ｍｇ，ｑ１２ｈ，共４～６次，妊娠率为３％。二者差异有显著性（Ｐ＜０．０５）。两者引起出血类型和时间均与正常月经相似，且无明显副反应发生，错过了服用传统房事后避孕药时，采用本研究的方法可不考虑性生活时间、次数。这种方法提供了一种新型有效避孕方法。     

An exploratory analysis of risk factors for childhood malignant germ-cell tumors: report from the Childrens Cancer Group (Canada,United States)

A study of 105 patients with childhood malignant germ-cell tumors (MGCT) and 639 community controls was conducted utilizing a large epidemiologic database collected by the Childrens Cancer Group from 25 member institutions in the United States and Canada. This study was designed to explore the risk factors of this malignancy whose etiology remains poorly understood. A structured, self-administered questionnaire was used to collect exposure information, and data were analyzed using an unconditional logistic regression model with adjustment for relevant confounders. Consistent with the findings from studies of adult MGCT, gestational age was associated inversely with risk of MGCT, with a 70 to 75 percent reduction in risk for children born at term compared with those born pre-term. Parental, particularly maternal, self-reported exposure to chemicals or solvents (odds ratio [OR]=4.6, 95 percent confidence interval [CI]=1.9–11.3) and OR=2.2, CI=1.1–4.7 for maternal and paternal exposure, respectively) and plastic or resin fumes (OR=12.0, CI=1.9–7.5.0 [maternal] and OR=2.5, CI=1.0–6.5 [paternal]) were associated with elevated risk of MGCT. New findings, not reported previously, include a positive relationship of MGCT risk with birthweight and prolonged breastfeeding, an inverse association between MGCT risk and number of cigarettes smoked by the mother during pregnancy, and a 3.1-fold increased risk (CI=1.5–6.6) associated with maternal urinary infections during index pregnancy. Although these findings need confirmation from future studies, they suggest a potential influence of in utero exposure to maternal endogenous hormones, parental environmental exposures, and maternal diseases during pregnancy in the development of childhood MGCT.Drs Shu, Nesbit, and Robison are affiliated with the Department of Pediatrics, Medical School, University of Minnesota, Minneapolis, MN, USA.

Identification of potent and novel alpha4beta1 antagonists using in silico screening

The antigen alpha4beta1 (very late antigen-4, VLA-4) plays an important role in the migration of white blood cells to sites of inflammation. It has been implicated in the pathology of a variety of diseases including asthma, multiple sclerosis, and rheumatoid arthritis. We describe a series of potent inhibitors of alpha4beta1 that were discovered using computational screening for replacements of the peptide region of an existing tetrapeptide-based alpha4beta1 inhibitor (1; 4-[N'-(2-methylphenyl)ureido]phenylacetyl-Leu-Asp-Val) derived from fibronectin. The search query was constructed using a model of 1 that was based upon the X-ray conformation of the related integrin-binding region of vascular cell adhesion molecule-1 (VCAM-1). The 3D search query consisted of the N-terminal cap and the carboxyl side chain of 1 because, upon the basis of existing structure-activity data on this series, these were known to be critical for high-affinity binding to alpha4beta1. The computational screen identified 12 reagents from a virtual library of 8624 molecules as satisfying the model and our synthetic filters. All of the synthesized compounds tested inhibit alpha4beta1 association with VCAM-1, with the most potent compound having an IC(50) of 1 nM, comparable to the starting compound. Using CATALYST, a 3D QSAR was generated that rationalizes the variation in activities of these alpha4beta1 antagonists. The most potent compound was evaluated in a sheep model of asthma, and a 30 mg nebulized dose was able to inhibit early and late airway responses in allergic sheep following antigen challenge and prevented the development of nonspecific airway hyperresponsiveness to carbachol. Our results demonstrate that it is possible to rapidly identify nonpeptidic replacements of integrin peptide antagonists. This approach should be useful in identification of nonpeptidic alpha4beta1 inhibitors with improved pharmacokinetic properties relative to their peptidic counterparts.
