纯氧和空气复苏患儿24个月随访观察

目的 探讨纯氧和空气复苏对新生儿发育的影响,为新生儿复苏用氧选择提供依据.方法 对2005年1月-2007年1月在保定市妇幼保健院进行窒息复苏的30例患儿在24个月时进行随访,依据复苏用氧浓度分为纯氧复苏组(20例)和空气复苏组(10例),内容包括出生时胎龄、出生体重、身长、头围、阿氏评分(1 min,5 min)、心率(1 min,5 min)、随访时体重、身长、头围及运动发育标志(坐、爬、站、走时间).结果 出生时患儿身体数据差异无统计学意义,24个月随访,患儿身高、体重、头围及运动发育标志差异均无统计学意义(P>0.05).结论 空气复苏对新生儿窒息患者是安全有效的.     

Working‐correlation‐structure identification in generalized estimating equations

Selecting an appropriate working correlation structure is pertinent to clustered data analysis using generalized estimating equations (GEE) because an inappropriate choice will lead to inefficient parameter estimation. We investigate the well‐known criterion of QIC for selecting a working correlation structure, and have found that performance of the QIC is deteriorated by a term that is theoretically independent of the correlation structures but has to be estimated with an error. This leads us to propose a correlation information criterion (CIC) that substantially improves the QIC performance. Extensive simulation studies indicate that the CIC has remarkable improvement in selecting the correct correlation structures. We also illustrate our findings using a data set from the Madras Longitudinal Schizophrenia Study. Copyright © 2008 John Wiley & Sons, Ltd.

桡骨远端关节内骨折外固定器治疗的相关机制和原则探讨

目的 分析和探讨桡骨远端关节内骨折外固定器治疗的相关机制和原则.方法 笔者采用Orthofix外固定器和国产组合式外固定器治疗桡骨远端关节内骨折45例46肢,以齐藤英彦法对资料完整的37例38肢病例进行分型,分析其影像学表现、损伤和治疗相关机制以及特点.结果 各型复位方向和外固定腕关节位置均与致伤暴力方向相反.骨折愈合时间平均为43 d(37～62 d),平均随访时间14个月(3～56个月),按Dienst标准评估腕关节功能及疗效:优21例22肢,良10例10肢,可6例6肢.结论 闭合复位外固定能很好地解决桡骨远端关节内骨折的治疗问题,特别适用于粉碎型关节内骨折.其治疗原则是复位方向及腕关节外固定位置与损伤机制、移位情形相反,个别骨折块辅以切开复位时须强调有限切开,必须重视部分病例伴有的同侧桡骨中远段骨折和同侧尺骨远段骨折的处理.     

Trans fat intake lowers total cholesterol and high-density lipoprotein cholesterol levels without changing insulin sensitivity index in Wistar rats

Epidemiologic studies have demonstrated that trans fat intake increases the risk of some chronic diseases. We hypothesize that trans fat intake would increase the risk of cardiovascular disease and type 2 diabetes mellitus by changing the lipid profile in plasma, the secretion of adipokines in adipose tissue, and the insulin sensitivity. Accordingly, the major objective of present study was to investigate the effect of dietary intake of trans fat on lipid profile, insulin sensitivity, and adipokine levels in plasma. Two groups of Wistar rats were fed a diet containing 4.5% trans fat or a control diet containing no trans fat for 16 weeks. Fasting glucose level was monitored every 2 weeks. At the end of feeding experiment, blood, heart, kidney, liver, omental adipose tissue, and semitendinosus muscle were collected. The trans fat content in organs, lipid profile, adipokine, insulin, and glucose levels in plasma were analyzed. The trans fat content in adipose tissue, heart, kidney, liver, and muscle of rats fed trans fat were 169.9, 0.6, 1.2, 1.7, and 2.5 mg/g samples, respectively. The trans fat content in these organs contributed to 15.9%, 1.2%, 2.3%, 4.3%, and 6.1% of the total fat, respectively. The plasma glucose level, insulin level, and insulin sensitivity index were not significantly different between the trans fat and control groups. The results indicated that trans fat intake might not be related to insulin resistance. However, lipid profile and plasma adipokine levels were significantly changed after trans fat feeding. The trans fat fed group showed significantly lower total cholesterol and high-density lipoprotein cholesterol levels than the control group. The decreased high-density lipoprotein cholesterol level may indicate the detrimental effect of trans fat intake on lipid profile. Adiponectin and resistin levels were significantly higher in the trans fat group than the control group. Leptin levels were significantly lower in the trans fat group than the control group. The results indicated that dietary intake of trans fat can significantly change the adipokine levels, but the possible links between adipokine level change caused by trans fat intake and metabolic effects of this change need further investigations.     

王成荣治疗子宫内膜异位症“火热致瘀”理论探讨

王成荣研究员长于以中医药诊治子宫内膜异位症（EMT），根据其临床经验认为“火热致瘀”是EMT的基本病因、病机，且火热与瘀血互为因果、恶性循环，致使EMT病程缠绵不愈、反复复发。王老据此提出“清热解毒、化瘀散结”的治疗法则，为治疗EMT开辟了另一思路和理论。
