血浆血栓素B2和6-酮-前列腺素F1α水平与新生儿窒息关系

为观察不同程度窒息新生儿血浆血栓素B2(TXB2)和6-酮-前列腺素F1α(6-Keto-PGF1α)含量变化及其规律,选择对照组20例,轻度窒息组19例,重度窒息组21例,均在生后6 h内取股静脉血2 ml,进行放射免疫分析.结果TXB2及其与6-Keto-PGF1α比值在对照组分别为(202.42±53.91)pg/ml、1.81±0.61,轻度窒息组分别为(646.29±121.66)pg/ml、3.73±1.27,重度窒息组分别为(1443.27±254.61)pg/ml、6.83±2.39,三组方差分析,组间差异有显著性(F值分别为286.19,49.78,P＜0.001);6-Keto-PGF1α升高,三组分别为(117.22±33.14)Pg/ml、(184.73±52.65)pg/ml、(223.45±63.48)pg/ml(P＜0.05).提示窒息新生儿血浆TXB2和6-Keto-PGF1α含量及两者之比明显升高,重度窒息组比轻度窒息组升高明显;与对照组相比,其升高程度与窒息程度有关.     

Identifying Risk Drinking in Expectant Fathers

Abstract: Background: Identification of risk drinking in expectant fathers may be helpful as an important part of efforts to minimize maternal alcohol use, and as an opportunity to inform them about a problematic practice during a critical developmental stage for the couple. The purpose of this study was to evaluate the T‐ACE screening questionnaire, which asks about t olerance to alcohol, being a nnoyed by other's comments about drinking, attempts to c ut down, and having a drink first thing in the morning (“ e ye‐opener”), in the male partners of pregnant women who themselves were T‐ACE positive. Methods: Two hundred fifty‐four male partners were asked to complete the T‐ACE embedded in a health survey, the Alcohol Use Disorders Identification Test (AUDIT), and other questions about their alcohol use in the past 30 days when their pregnant partners had a median gestation of 11.5 weeks (T₁). After delivery, male partners again completed the T‐ACE and quantity‐frequency questions (T₂). The predictive ability of the T‐ACE and AUDIT was compared, using risk drinking (>4 drinks/day or >14 drinks/week) as the criterion standard. Results: A substantial minority of male partners had risk drinking, 31 percent at T₁ and 25 percent at T₂. Although the AUDIT was better than the T‐ACE as an independent predictor of risk drinking, the latter was most accurate when the tolerance threshold exceeded 2 drinks, the same established for pregnant women. The sensitivity (T₁ = 84.6%, T₂ = 82.8%) and specificity (T₁ = 43.8%, T₂ = 51.1%) of the T‐ACE at this threshold compared favorably with those of the AUDIT at the standard cut point of 8. Conclusions: The T‐ACE may be a practical way for clinicians to identify risk drinking in both pregnant women and expectant fathers. (BIRTH 33:2 June 2006)     

儿科背式输液架的研制与应用

输液架是医院不可缺少的工具之一，国内医疗单位使用的输液架多种多样，但仅适用于病房使用，而适合儿科患儿移动的背式输液架甚少。针对以上缺陷，我们自行设计了一种可调式背式移动输液架，已应用于500例儿科患儿，效果较好。现介绍如下。

小儿糖尿病血胰岛细胞抗体与胰岛素自身抗体

报道并分析20例小儿糖尿病患儿的临床资料及血胰岛细胞抗体(ICA)及胰岛素自身抗体(IAA)的测定资料。在20例患儿中,临床表现多不典型。在酮症酸中毒的治疗中小剂量胰岛素疗法方法简便,安全可靠,并发症少。本组患儿ICA阳性率55%,IAA阳性率30%,经卡方检验均显著高于对照组,推测病毒感染引起自身免疫反应,产生ICA及IAA而致本病发生。     

DNA-Methylierung von monohalogenierten Methanen in F-344 Ratten

Monohalogenated methanes (methyl chloride, methyl bromide and methyl iodide) are mutagenic and carcinogenic. The possible mechanism of these effects, DNA methylation, was studied. DNA adducts from orgnas of F344 rats exposed to these chemicals were separated and identified with high performance liquid chromatography (HPLC) and gaschro-matography/massspectrometry (GC/ MS). DNA adducts, 7-methylguanine (7-MeG) and O⁶-Methylguanine(0⁸-MeG), incorporation of¹⁴C into de novo synthesis of nucleobases could be observed in enzymatic DNA hydrolysates by HPLC and determination of the radioactivity in the fractions. The formation of DNA add,ue,ts in the studied organs was only quantitatively different. The formation of O⁶-MeG was further pioved by analysing the acidic hydrolysates using HPLC with non-radioactive O⁶MeG as internal standard. 7-MeG and 3-MeA were identified with GC/MS analysis.
