Zolpidem induced nocturnal sleep‐related eating disorder (NSRED) in a male patient

Nocturnal Sleep‐Related Eating Disorder (NSRED) is a well‐documented sleeping disorder where the person is reported to experience bizarre eating behavior during sleep. Although various causes are implicated in this disorder, role of drugs cannot be ruled out. Here we narrate an interesting rare case report of a drug‐induced new onset NSRED, where a 45‐year‐old man on zolipdem performed an unexpected and bizarre eating behavior during somnambulistic state, type of which has not been reported earlier in the literature. The case falls under even rarer category as such behavior in sleep is reported mainly in woman. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009     

152例老年高血压病的诊治体会

目的:观察中西医结合治疗老年高血压的疗效。方法:将152例老年高血压患者随机分成两组,对照组76例采用西药治疗,治疗组76例除用西药治疗外辅助中药治疗。结果:治疗组显效30例,有效44例,总有效率97.4%;对照组显效24例,有效40例,总有效率为84.2%。结论:中西医结合治疗老年高血压有较好的疗效。     

水稻亚种间杂种优势利用研究

本试验探讨了华南双季稻区利用亚种同杂种优势的特点和问题,结果表明:当前,两系亚种问杂种一代主要存在的问题是结实率低和谷草比低;籼粳交杂种易受环境条件的影响;每穗实粒数和单株有效穗数是决定单株产量的重要因子;每穗实粒数增加的关键在于结实率的提高,本文还就提高结实率和谷草比等问题提出了意见。     

A Biomechanical Double Sac (Pericardium-Pebax) for Specially Shaped Artificial Ventricles: A Computerized Study to Evaluate Its Mechanical and Volumetric Properties

Abstract: For original ovoid shaped artificial ventricles. a biomechanical double sac consisting of a biological sac (porcine pericardium) as the blood contact interface and a synthetic sac (Pebax 3533) as the mechanical support to assume systolic-diastolic dynamic constraints was conceived. The volumetric and mechanical properties were assessed with a three-dimensional modeling of Pebax sacs and computerized simulations of their systolic distortions for both right and left ventricular configurations. The stresses and strains of these sacs were represented as quantitative mappings for a maximum end-systolic state and were below the respective threshold values above which the Pebax material is jeopardized for permanent structure impairment. After fatigue tests applied on Pebax strips under the alleged working conditions of Pebax sacs, the material structure was unchanged and maintained its intrinsic mechanical properties. The theoretical maximum stroke volumes were 74.4 cm³ and 62.4 cm for the left and right ventricular configurations, respectively. With these mechanical and volumetric features, the biomechanical double sac concept was considered valid and could be provided for a consequent specific total artificial heart.     

动态监测胃黏膜内pH值对胆源性胰腺炎外科治疗的价值

目的探讨胃黏膜内pH值对胆源性胰腺炎病情预后评估及在决定手术冶疗中应用的价值。方法对确诊的146例胆源性胰腺炎患者经鼻插入胃黏膜二氧化碳张力计（TRIP-NGS导管）测定胃黏膜内pH值，每隔12小时测定一次，并进行APACHEⅡ评分，将2组数据与外科治疗进行相关分析。结果①pH值变化反映胆源性胰腺炎病情发展变化，与器官衰竭数呈负相关；②外科干预治疗与内科治疗比较差异有统计学意义（P〈0．05）；③pHI〉7．25与pH〈7．25患者开腹手术病死率和细菌培养阳性率比较差异有统计学意义（P〈0．05）。结论pH值对胆源性胰腺炎外科治疗有指导意义。外科处理原则是：①胆道无梗阻，以内科保守治疗为主；②伴胆道梗阻，先行经内镜十二指肠乳头括约肌切开术、经内镜鼻胆管引流术、B超导引引流、腹腔灌洗等，如胆道引流不畅或pH值持续下降，则开腹手术。     

CT图象的面罩式覆盖法定量诊断脂肪肝

目的　探讨脂肪肝的脂肪浸润程度的无创性检查方法及临床意义。方法　用 GE 30 0 0 I CT机扫描 36例脂肪肝患者肝脏、脾脏 ,用 CT机配备软件处理数据 ,面罩式覆盖法计算肝脏各个层面的脂肪面积与对应层面肝脏面积 ,并得出比值 (脂肪浸润指数 )。用生化仪检测肝功能指标。肝穿刺病理检测肝组织内脂肪浸润程度。结果　平均脂肪浸润指数与肝功能状态呈显著正相关 ,亦与肝穿刺的病理结果呈正相关 (r=0 .86 5 ,P<0 .0 1)。结论　 CT图象面罩式覆盖法对脂肪浸润的定量分析是诊断脂肪肝可靠的无创性检查方法 ,对非均匀性脂肪肝该方法优于肝穿刺
