The National Summit on Preconception Care: A Summary of Concepts and Recommendations

The Centers for Disease Control and Prevention (CDC) and 35 partner organizations have engaged in developing an agenda for Preconception Health. A summit was held in June 2005 to discuss the current state of knowledge regarding preconception care and convene a select panel to develop recommendations and action steps for improving the health of women, children, and families through advances in clinical care, public health, and community action. A Select Panel on Preconception Care, convened by CDC, deliberated critical related issues and created refined definition of preconception care. The panel also developed a strategic plan with goals, recommendations, and action steps for improving preconception health. The recommendations and action steps are specific to the implementation of health behavior, access, consumer demand, research, and surveillance activities for monitoring and improving the health of women, children and families. The outcome of the deliberations is the CDC publication of detailed recommendations and action steps in the Morbidity and Mortality Weekly Report series, Recommendations and Reports.

Pelvic granulocytic sarcoma

 Granulocytic sarcoma is an uncommon extraskeletal tumor most frequently associated with leukemia. We present a case of bone location with unusual pattern in a patient with no evidence of myeloproliferative disorder at presentation or follow-up.     

Erythrodermic bullous pemphigoid

We report a case of erythrodermic type of bullous pemphigoid which is a rare variant of bullous pemphigoid. Our patient had a peculiar clinical presentation with bullae, erosions and extensive erythrodermic areas, and distinct direct immunofluorescent findings which included linear IgG and C3 deposits in the basement membrane and also IgG in the intercellular spaces. Very high levels of serum IgE were also detected in our patient.     

冠状动脉手术复查患者中无症状性颈部血管杂音对颈动脉疾病的预测价值

目的:在接受冠状动脉搭桥术(CABG)的患者中研究无症状性颈部血管杂音对检测颈内动脉疾病的预测价值。设计:一项前瞻性队列研究。背景:三级转诊大学医院。患者:连续153例施行CABG的患者,平均年龄57岁,既往无脑血管病史。干预措施:患者行详细的术前检查,包括冠状动脉造影和颈动脉     

多巴酚丁胺负荷对缺血性扩张型心肌病患者左心室充盈的影响：病理生理学及预后意义

目的：本研究旨在探讨多巴酚丁胺对缺血性心肌病（ICM）患者左心室（LV）充盈功能的影响，并确定峰值负荷时限制性充盈型（RFP）是否具有预后预测价值。背景：ICM患者峰值负荷时RFP的预后价值尚属未知。方法：在静息和负荷情况下，采用多普勒超声心动检查研究了69例ICM患者；RFP定义为跨二尖瓣E／A比≥1．0、等容舒张时间（IVRT）〈80ms及E波减速时间（EDT）〈120ms。结果：69例患者中有42例静息时出现RFP，其中有24例患者负荷情况下转变为非RFP（EA），18例患者RFP持续存在（EE）；69例患者中27例静息和峰值负荷时均无RFP（AA）。     

Immunochemical characterization of cytochrome P-450 isozymes responsible for benzene oxidation in the rat liver

The contribution of cytochrome P-450 isozymes to benzene metabolismin liver microsomes from fed, fasted, pyrazole-, pbenobarbital(PB)- and ethanol-treated rats and in respective isocaloriccontrols was investigated using monoclonal antibodies (mAbs).Clone 1-7-1 mAb did not inhibit benzene metabolism, whereasclone 2-66-3 inhibited only in PB-induced microsomes at a highconcentration of benzene (6.26 mM), and clone 1-91-3 mAb inhibitedbenzene metabolism in all cases. The degree of inhibition wasas follows: fed isocaloric control PB < fasted < pyrazole ethanol. The pattern of inhibition was similar with clone 1-91-3for low (0.23 mM) and high concentrations of benzene, exceptin PB-induced mkrosomes. Western blot analysis showed that clone1-7-1 mAb did not bind any liver mkrosomal protein in the regionof cytochrome P-450s, whereas with clone 2-66-3 a clear-cutband was seen only in liver microsomes from PB-treated rats,with clone 1-98-1, a band was detected in mkrosomes from alltreated groups, in the following order: PB = isocaloric control< fed < fasted < pyrazole < ethanol. These resultsindicate that (i) cytochromes P-450b,e and P-450J contributeto benzene metabolism in rat liver; (ii) the former has a lowaffinity to benzene and is induced by PB; and (iii) P-450J hasa high affinity to benzene and is induced by 1-day fasting,pyrazole and ethanol, but decreased by PB treatment.
