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)     

发育期大鼠高热惊厥前后海马γ-氨基丁酸B受体亚基表达的变化

目的：研究高热惊厥(febrile seizures，FS)对发育期大鼠脑内γ-氨基丁酸(γ-aminobutyric acid，GABA)B受体亚基GABABR1与GABARR2蛋白表达的影响。方法：采用热水浴诱导大鼠高热惊厥模型。隔日诱导惊厥1次，共诱导10次，末次惊厥后24h处死大鼠。发育期大鼠随机分为3组：对照组(n＝24)，1次高热处理组(n＝28)，10次高热处理组(n＝40)。高热处理组根据是否出现惊厥再分为1次高热惊厥组(FS1，n＝16)与1次高热未惊厥组(F1，n＝12)，10次高热惊厥组(FS10，n＝15)与10次高热未惊厥组(F10，n＝13)。采用免疫组化方法观察不同次数高热惊厥大鼠脑内GABABR1与GABABR2蛋白表达的变化。结果：FS10大鼠海马齿状回、CAl-CA3区GABABRl和GABABR2蛋白表达明显低于F10、F1、FSl和对照组；F10大鼠上述脑区GABABRl和GABABR2蛋白表达低于F1、FS1和对照组；F1及FS1大鼠与对照组相比差异无显著性；海马各区GABABR1与GABABR2表达的改变大部分平行，但10次高热惊厥后GABABR2在CA1—CA3区下降更明显，而GABABR1在齿状回下降更明显。结论：反复高热惊厥及反复高热均可使发育期大鼠脑内GABABR亚基蛋白表达降低，高热惊厥的影响较单纯高热更为明显，提示GABABR亚单位与发育期大鼠高热惊厥及其脑损伤密切相关。GABABR1与GABABR2改变的不平行可能与受体亚单位组合的可塑性改变有关，这种改变可能导致抑制功能的改变。     

Study on therapeutic mechanism of Neiyifang in treating endometriosis

Objective: To observe the clinical effect of Neiyifang (NYF) in treating endometriosis and to explore its therapeutic mechanism through observing its influence on plasma β-endorphin (β-EP) in different menstrual stages and levels of prostaglandins (PGs) in menstruation.Methods:NYF was administered to 104 patients with endometriosis one dose daily with 3 successive menstrual cycles as one therapeutic course. Peripheral blood β-EP level in follicular, luteal and menstrual stages, as well as PGF_2α, PGE2, thromboxane B₂ and 6-keto-PGFl α levels in menstrual stage were detected by RIA, and controlled with those in 15 healthy persons.Results: (1) The total effective rate of NYF was 81.3% and it showed significant effect in improving patients’ clinical symptoms and physical signs; (2) In menstrual stage, the levels of β-EP, 6-keto-PGF_α/ TXB₂ were lower(P <0.05) and levels of PGF_2α, PGE₂, TXB₂ and 6-keto-PGF_1α were higher (P< 0. 05) in patients than those in control, and the higher the level of PGE₂, the severer the menalgia, (3) NYF could increase levels of β-EP, 6-keto-PGF_1α, and reduce levels of PGF_2α, PGE_2α in menstrual stage of patients (all P<0.05).Conclusion: (1) NYF has good clinical effect in treating endometriosis; (2) Patients’ symptom of menalgia is closely related with the excessive high levels of PGF_2α and PGE₂, PGI₂/TXA₂ ratio disturbance, and excessive low level of β-EP; (3) NYF could significantly decrease the PGE₂, PGF_1α levels, increase the 6-keto-PGF_1α/TXB₂ ratio and the level of β-EP, so as to alleviate the menalgia in patients with endometriosis.

棕榈油对成人血脂和血小板功能的影响

报道了棕榈油（ＰＡ），花生油（ＰＥ）对血清总胆固醇水平（ＴＣ）在５．５～７．０ｍｍｏｌ／Ｌ的受试者血脂和血小板功能的影响。５１名受试者（男３１人，女２０人，年龄３０～６６岁之间）分为两组，一组男１５人，女１１人，称ＰＥ组；另一组男１６人女９人，称ＰＡ组，预备期３周，膳食以当地日常食用的花生油烹调，实验期６周。ＰＡ组受试者食用以棕榈油烹调的实验膳；ＰＥ组受试者仍食花生油烹调的膳食。脂肪约占膳食能量的３０％，其中６０％～６５％来自实验油。实验结果表明：与起始值相比，６周末ＰＡ组受试者血清ＴＣ，低密度脂蛋白胆固醇（ＬＤＬ－Ｃ）和总胆固醇与高密度脂蛋白胆固醇比值（ＴＣ／ＨＤＬ－Ｃ）显著下降，血浆血栓素Ｂ２（ＴＸＢ２）／６－酮前列环素Ｆ１α、（６－ｋｅｔｏ－ＰＧＦ１α）比值显著下降，全血血小板聚集率未见显著变化。ＰＥ组受试者的血脂、血浆ＴＸＢ２、６－ｋｅｔｏ－ＰＧＦ１α及全血血小板聚集率等指标均未出现显著变化。提示，棕榈油作为我国居民家庭烹调用油并不会增加发生心血管疾病的危险。     

乙型脑炎、麻疹胎传母体抗体的调查

86对母婴血清标本用间接酶联免疫测定法(ELISA)测定了乙型脑炎抗体,118对用血凝抑制(血抑)试验测定了麻疹抗体。结果发现,脐血乙型脑炎抗体阳性率为79.1％,母血为74.4％,几何平均滴度在脐血显著高于母血(t=5.1857,P<0.01),比值为1.2∶1。脐血和母血的麻疹血抑抗体阳性率分别为86.4％及84.8％,几何均值也是前者高于后者(t=4.0349,P<0.01),比值为1.3∶1。 108份婴儿血清标本测定结果显示,0～3个月婴儿乙型脑炎抗体阳性率为35％,4～9个月仅为13％,10个月及以上的婴儿全部阴性。此结果与近年上海市小于1岁组乙型脑炎发病率最高相一致,提示应考虑提早乙型脑炎疫苗的接种年龄。
