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)     

甲状腺~(99)Tc~mO_4~-显像冷结节的临床诊断价值

目的　探讨甲状腺99TcmO-4 显像冷结节对不同性质甲状腺疾病的诊断价值。方法　采用静脉注射99TcmO-4 185MBq ,2 0min后甲状腺前位静态显像 ,采集总计数 1× 10 6。显像显示甲状腺结节局部放射性分布缺损或低于正常甲状腺组织则定性为冷结节。结果　 34 2例甲状腺99TcmO-4 显像发现冷结节 85例 ,发生率为2 4.9% ,85例冷结节中 ,37例 (4 3.5 % )为甲状腺瘤 ,15例为甲状腺癌 (17.6 % ) ,2 0例 (2 3.5 % )为结节性甲状腺肿 ,8例 (9.4% )为甲状腺炎 ,4例 (4 .7% )为单纯性甲状腺囊肿 ,1例 (1.3% )为甲状腺外肿物。结论　冷结节在甲状腺99Tcm O-4 显像时较为常见 ,且不同性质甲状腺疾病的冷结节及其周围组织有一定的特征性表现 ,因此99TcmO-4显像冷结节对甲状腺腺瘤、甲状腺癌、甲状腺囊肿、甲状腺炎等常见疾病具有较高的临床价值。     

928株革兰阴性杆菌耐药性监测

目的：了解青岛地区临床分离的重要革兰阴性杆菌的耐药情况以指导合理用药。方法：2001年青岛3家医院临床分离的5种革兰阴性杆菌用Kirby-Bauer法进行药敏试验。结果：5种病原菌均占3家医院革兰阴性杆菌分离率的前5位，大肠埃希菌对氟喹诺酮类药物的耐药率达60％－87％，细菌对亚胺培南均呈高度敏感，但铜绿假单胞菌耐亚胺培南株占25．8％，头孢他啶的抗菌活性是三代头孢菌素中最高的；复方酶抑制剂表现出良好的抗菌活性。结论：细菌耐药问题仍是目前临床的严重问题，地域性的耐药性监测是必要的。     

心理因素对小学生脑力工作能力影响的研究

采用横断面研究方法，对180名小学三年级学生脑力工作能力与其智力、性格、学习动机等心理因素和学习、睡眠时间等作息因素的关系进行分析研究。验证了学习、睡眠时间是影响学生脑力工作能力重要的外部因素；脑力工作能力与智力和学习成绩呈正相关。学生自身的心理因素中，学习动机对脑力工作能力有重要影响，所以激发和强化学生的学习动机，是保持和提高学生学习工作能力的有效手段；而性格内外向性、情绪稳定性等因素，对脑力工作能力的影响不明显。     

Diagnosis of ligament rupture of the ankle joint: Physical examination, arthrography, stress radiography and sonography compared in 160 patients after inversion trauma

We prospectively enrolled 160 consecutive patients with inversion trauma of the ankle in a diagnostic protocol that included physical examination within 2 days and at 5 days after trauma, arthrography, stress radiography, and ultrasonography. 135 patients had pathological lateral ligament laxity on the later physical examination or lateral ligament rupture diagnosed on arthrography and they were operated on. 122 of these patients had ligament ruptures.

At clinical follow-up after a minimum of half a year, all of the patients who were not operated on had stable joints without signs of previous ligament ruptures.

Delayed physical examination at 5 days after the injury led to the highest overall sensitivity (96%) and specificity (84%) for the detection of a ligament rupture. Additional diagnostic procedures, at a considerable cost, yielded little additional information.     

离体牙上釉珠的观测与临床意义

本文从12379枚离体牙上观测了釉珠的发生率、发生部位、形态、直径大小。结果釉珠的发生率为2.49％,以上颌第三磨牙发生率最高,下颌第一磨牙次之。最常发生的部位是在冠颈部的根分叉处,上颌磨牙的釉珠多呈园形,下颌磨牙釉珠多呈梭形。釉珠最大直径为3.2mm,最小为0.5mm,平均为1.56mm。结合文献认为釉珠是一种牙齿形态发育异常,它对牙周病的发生、发展、治疗与预后有重要影响,口腔科医师对这种牙齿形态变异应予以重视。     

转hCTLA4Ig树突状细胞诱导T细胞免疫耐受的实验研究

目的　通过逆转录病毒载体将人CTLA4Ig转染DCs ,探讨转人CTLA4Ig(hCTLA4Ig)树突状细胞 (DCsRev)诱导T细胞免疫耐受的可能性。方法　通过重组逆转录病毒将目的基因hCTLA4Ig转染到大鼠骨髓来源的DCs中 ,通过流式细胞检测目的基因hCTLA4Ig表达及DCs表面分子的改变 ;通过混合淋巴细胞反应 (MLR)检测DCsRev抑制T细胞免疫反应的能力。 结果　重组逆转录病毒转染DCs的最大效率为 91 2 5 % ;在功能上 ,DCsRev不但丧失了刺激MLR的能力 ,并且能够强烈抑制MLR中反应T细胞的增殖 ,而且抑制率与加入DCsRev的数量和DCsRev预处理反应T细胞的时间长短有关。具体来说 ,DCsRev数量在 10 3 ～ 10 4之间时 ,抑制率与剂量呈正相关 ,最高为 71 96%。而当DCsRev数量达到 5× 10 4抑制率下降为 5 9 2 %。在 12～ 48h之间 ,随着预处理时间的延长 ,抑制率却不断下降 ,预处理 12h抑制率最高 ,为 99 6%。但不做预处理 ,在反应开始时同时加入DCsRev ,则抑制率明显降低 ,仅为 5 9 2 %。对腹腔注射DCsRev大鼠脾T淋巴细胞体外分析表明 ,DCsRev也能在动物体内诱导耐受 ,但这种免疫耐受状态不能维持终身。结论　通过逆转录病毒载体将人CTLA4Ig转染DCs,不但DCs表面CD86分子被CTLA4Ig有效的封闭 ,并且能够诱导抗原特异性T细胞的免疫耐受
